CAS-12_PRESERVE AT RICE LAKE-JOHN KNOBLAUCH",NE501 o P Minnesota Department of Transportation Metropolitan District P Waters Edge Building 1500 County Road B2 West Roseville, MN 55113 July 23, 2014 Sharmeen Al-Jaff City of Chanhassen 7700 Market Boulevard PO Box 147 Chanhassen, MN 55317 ciTvRECEI EN JUL 2 81014 Ot%ASft DEPT SUBJECT: Preserve at Rice Lake, MnDOT Cooperative Construction Review North side of US 212, East of MN 101 Chanhassen, Carver County Control Section 1013 Dear Ms. Al -Jaffa MnDOT has reviewed the latest plans for the US 212 noise wall for the Preserve at Rice Lake development and has the following comments: Additional Information Needed: For safety reasons, the developer will not be permitted to access the site directly from US 212. The developer will need to stage construction from the local roads and from within the development. MnDOT will need to see the construction limits as well as a traffic control plan for access during construction. If it is determined that the wetlands cannot be avoided during construction, temporary impact permits will likely be needed from the Corp of Engineers and MnDOT through the Wetland Confirmation Act. Please submit a copy of the latest sediment/erosion control plan showing how the wetlands in MnDOT right-of-way will be protected during construction. MnDOT received a few noise wall offsets but more information is needed to review the wall in relationship to TH 212. Submit the clear zone calculations and cross sections of the wall showing the wall's relationship to the edge of TH 212 travelway. Currently Under MnDOT Review: MnDOT recently received the updated noise wall foundations report. The review of this report will be expedited and comments will be provided soon. MnDOT is currently reviewing the impact to trees within our right-of-way. The review of this information will also be expedited and comments will be provided soon. If vegetation is impacted, there may be a cost associated with any removals. There also could be special vegetation protection measures required to protect vegetation which will remain following the project. Design: Plan sheet 3 calls for Noise Wall Type No. 2. Noise Wall Type No. 1 is the only wall type that accepts a rubrail. Plan sheet 7 notes that rubrail is to be installed on Noise Wall Type No. 1 but Sheet 10 shows the rubrail attached to Noise Wall Type No. 2. Please revise the conflicting information. Both MnDOT Standard Plans 5-297.661 for Wood Planking Noise Barrier with Concrete Posts and 5-297.678 for Glue Laminated Rubrail (Concrete Posts) have been revised. MnDOT recommends that this plan include the most recent set of standard plans. When there are modifications to the MnDOT standard plans show the change with a cloud around the change or note it with an asterisk and a note. For questions concerning these comments, please contact Nancy Jacobson (651-234-7647) in MnDOT Metro District's Design Section. Drainage: There needs to be a minimum gap of two inches and a maximum gap of 4" under the noise wall to facilitate drainage. Bridges: The yellow highlighted areas of the attached specifications need to be completed and information filled in. Since the noise wall is to be constructed in MnDOT right of way, the paint color of the wall needs to be coordinated with MnDOT (Bridge Office or Landscape Architecture Unit). The Bridge Office Contact is Melissa Schultz (651-366-4465). Review Submittal Options: MnDOT's goal is to complete the review of plans within 30 days. Submittals sent electronically can usually be turned around faster. Submit one of the following: 1. One pdf version of the plans. MnDOT accepts plans at metrodevreviews.dot@state.mn.us, provided that each e-mail is less than 20 megabytes. 2. Three sets of full size plans. Submitting seven sets of full size plans will expedite the review process. Send plans to: MnDOT — Metro District Planning Section Development Reviews Coordinator 1500 West County Road B-2 Roseville, MN 55113 3. One compact disk. 4. Plans can also be submitted to MnDOT's external FTP site. Send files to: ftp://ftp2.dot.state.mn.us/nub/incoming/MetroWatersEdge/Planning.

Box 147 Chanhassen, MN 55317 RECEIVES, SEP 16 2013 CITY OF CHANHASSEN RE: City of Chanhassen Preserve at Rice Lake Comprehensive Plan Amendment - Administrative Review Metropolitan Council Review File No. 20265-6 Metropolitan Council District No 4 Dear Mr. Generous: The Metropolitan Council received the City's Preserve at Rice Lake plan amendment on August 23, 2013. The amendment reguides 13.23 acres from Residential Low Density to Residential Low and Medium Density. The subject property is located north of Highway 212 and southeast of the intersection of West 86th Street and Tigua Lane. The purpose of the amendment is to allow dual guiding of property to accommodate a 16 -unit detached housing development Council staff finds the amendment meets the Comprehensive Plan Amendment Administrative Review Guidelines adopted by the Council on July 28, 2010. The proposed amendment does not affect official forecasts or the City's ability to accommodate its share of the region's affordable housing need. Therefore, the Council will waive further review and action; and the City may place this amendment into effect. Staff also offers the following advisory comment: The Council encourages efforts to promote the efficient use of water to protect and enhance the region's water supply sources. New development and redevelopment always provide opportunities to implement new water conservation and stormwater management strategies as part of construction and site landscaping. The Council's Conservation Toolbox and Stormwater Reuse Guide may be useful tools to reduce per capita water demand. Both can be found on the Council's Water Supply Planning website at htip://www.metrocouncil.org/Wastewater- Water/Plannin Water-Supply-Plannina/Guidance-and-Planning-Tools asR . The amendment, explanatory materials, and the information submission form will be appended to the City's Plan in the Council's 'Iles. If you have any questions please contact Angela R.

All voted in favor and the motion carried unanimously with a vote of 5 to 0. Mayor Furlong: Thank you everyone. We'll look forward to getting those responses and then we will see this back at our next meeting, is that right Mr. Gerhardt? I think you mentioned August 11t1. Oh, Mr. Sticha. Greg Sticha: You will not see this back at the August 11 t1 meeting. The bonds will actually be issued by the Carver County CDA. This is giving them the authority to go ahead and use our G.O. to go ahead and do that so we won't be awarding the bid of the bonds. Mayor Furlong: Okay. Greg Sticha: That will be done by them so, but we'll get you that information first thing in the morning in regards to the $128,000. Mayor Furlong: Is that going to meet everybody's expectations? Okay, thank you. Thank you for the clarification. Greg Sticha: Yep. Mayor Furlong: With that let's move on to the next item of business. INC.: A. CONSIDER APPROVAL OF FINAL PLAT. B. CONSIDER APPROVAL OF DEVELOPMENT CONTRACT, DRAINAGE AND UTILITY EASEMENT, TRAIL EASEMENT, AND CONSTRUCTION PLANS AND SPECIFICATIONS. Mayor Furlong: Let's start with a staff report please. Kate Aanenson: Thank you Mayor, members of the City Council. There's actually two items before you tonight. One is approval of the final plat and the second action item would then be approval of development contracts and drainage easements, trail easement and construction plans and specifications. Typically final plats are on consent but this has been almost a year since you've seen it so we thought we'd give you an update on the project. Mayor Furlong: Thank you. Kate Aanenson: Again it's located off of West 861. How you get access from 101 just north of 212. So for the background on this, what you saw almost a year ago when you approved, that would be August 12t1 of 2013 you approved multiple applications including a rezoning, a variance. Excuse.rezoning for a PUD. We actually changed that to get the lot size configuration to a medium density. A variance for the length of the cul-de-sac. We did site plan review because in the medium density we do require site plan review. Also wetland alteration permit to provide access road coming in off of 86t1 Street and then the subdivision for the 16 lots and 2 outlots and all this was predicated on the Metropolitan Council approving a Land Use Amendment so we did do dual guide this one too, and that was approved back in R1 SCANNED Chanhassen City Council — July 28, 2014 the fall of 2013 so what you're seeing tonight, all these things play into this project but what you're seeing again tonight is the final plat itself. So with that this is the layout of the plat with these 16 lots and 2 outlots. The trail access. We do have homes that we looked at that were being sited on this project and I just want to point out for example on Lot 3, there's each of the, you have a variety of choices to pick from but Lot 3 is a little bit more constrained as far as the number, or the choices of home plans that could go on there. Under the PUD a 30% hard cover so if you look at the plans, the house models that were presented at that time, the purchaser would have to be very careful in considering, and we hope with the direction of the developer that we're working to get the right sized homes on the lots so the homeowner has you know the expectation that they may be able to put a deck or some other things on the home that we don't maximize it right out of the gate. Again that Lot #5 would probably be the most challenging as far as the home choice so just want to apprise you of that. One of the other issues that's still outstanding is the noise wall. When we, the wetlands were originally put in place this area shown here on the wall, the wetland was a little bit greater so they needed additional encroachment from MnDOT. The applicant's aware of that but that is still document that still needs to come forward before this can actually get executed so if you were to approve this tonight those things would still before the staff would release that, would have to get that put in place. So with that there are again there's two motions. The motion for the final plat subject to the conditions in the staff report and then approval of the development contract and I'd be happy to answer any questions that you have. Mayor Furlong: Thank you. Any questions for staff? Councilwoman Ernst. Councilwoman Ernst: Kate can you tell me with the 800 foot setback, what is the surface going to be there? Is that going to be impervious with that, where that bare is? Kate Aanenson: The hard cover? The street? Councilwoman Ernst: Yeah. Kate Aanenson: That's what this is for. The length of the cul-de-sac, yes. Councilwoman Ernst: Oh okay. Kate Aanenson: It's for the street. Councilwoman Ernst: It's a private street, okay. Kate Aanenson: Yeah it's just for the length of the cul-de-sac. Councilwoman Ernst: Okay. Kate Aanenson: Yes. Councilwoman Ernst: Thank you. Mayor Furlong: Thank you. Councilman Laufenburger. Councilman Laufenburger. Thank you. Kate can you speak to the Findings of Fact, and let me give you specifically there are some, some of the Findings of Fact where you identify this condition no longer applies or this condition still applies. Can you talk fust of all a little bit, how is that a Findings of Fact no longer applies? Does that mean something has been resolved or can you just explain that? 12 Chanhassen City Council — July 28, 2014 Kate Aanenson: Sure. On this I would say we call those actually, the word we use is say findings. It's not Findings of Fact. It would be a finding of the condition of approval. The reason we do that is we like to be able to track for you if there's something that came up that was maybe a resident brought up or the council had a lot of interest in, we want to show you how that was modified. A lot of this is not only for the developer's edification but for the staff. If we go back and look at it, how it changed over time. For example tree locations. We might say that the road was changed so that is no longer applicable. There's some hydraulic issues that were addressed that we got additional information on. In this case that did happen. Some piezometers in getting additional water bounce in the area. Councilman Laufenburger: So over time as this project continues, as you continue to interact with the developer on the proposed project some of these things, based on decisions that are made, the findings are no longer important. Is that what you're saying? Kate Aanenson: Correct. It's like a checklist for the developer. For this project to go forward these things need to be met and a lot of them have been checked off so we show you that it's been met. Or it's been modified or it no longer applies. So that way we kind of streamline some of those conditions down. Councilman Laufenburger: Okay. I apologize for not bringing this to your attention earlier today but could you go to page 4. Kate Aanenson: Certainly. Councilman Laufenburger: Item 4(d). And what I notice is that the (d), it says this condition still applies but the sub -items i, ii, and iii, those conditions no longer apply. So are the sub -conditions i, ii and iii, are they not rolling up to d? Do you understand what I'm saying? Kate Aanenson: Yes Councilman Laufenburger: Now I'll give you some time to review that. Kate Aanenson: Yes, I'll let the City Engineer would like to comment on it too but what it's talking about is provide calculations or model demonstrating the City's requirements so the developer, they probably have submitted those calculations. Councilman Laufenburger: Okay. Kate Aanenson: So then that would eliminate some of the need for iron infiltration or, because there's other ways to approach stormwater management so some of those may have been. Councilman Laufenburger: Okay so it's, what you're saying is the items i, ii, and iii may not be, in this case may not be a summary or a roll up to item (d), is that what you're saying? Kate Aanenson: That's correct. They could operate independently. Councilman Laufenburger: Independently, okay. Kate Aanenson: That's correct. Councilman Laufenburger: Okay. Alight. That clarifies it, thank you very much Kate. 13 Chanbassen City Council — July 28, 2014 Kate Aanenson: It's very complex and honestly you know with 5 years we try to have a legacy. If someone went back to look at this project in 5 years, let's say it didn't get built out. Someone could really go through all the details here and really track what we were trying to accomplish. Councilman Laufenburger: Okay. Thank you very much Kate for taking that time to explain. Thank you Mr. Mayor. Mayor Furlong: Thank you. Any other questions for staff? Mr. Knoblauch, the applicant's here this evening. Anything you'd like to address the council this evening? Welcome. John Knoblauch: Good evening Mayor, council. Just one item that. Mayor Furlong: I'm sorry, if you could just introduce yourself. John Knoblauch: I'm sorry, John Knoblauch of 1450 Knob Hill Lane in Chanhassen. The, couple things. You know apologize for the kind of the delay in the project. My father, who was kind of my, I don't know if you want to call him my partner but my backer passed away in late October last year so we've kind of had a shifting of the guard a little bit if you will and so we didn't move the project along as fast as obviously we would have liked to. But now it's a little more pertinent that we would really like to grade this project on the drier part of the year and with MnDOT's got just a couple of is to cross and I's to dot here on their noise wall, that at least I'm aware of. Other than that it's very, very close to I think to meet all the requirements we've accomplished up to this point. But to get this graded in a drier part of the year I think is important just because of the wetland as is, which has been approved there by Outlot B. It's going to be best to do that in the drier part of the year, which is September. August, September, October so we really would like to get this project underway. Get blacktop in obviously before the cold sets in, which is doable right now but if we go too much farther we'll probably get into some tougher weather. As far as MnDOT, the only thing that's left on their plate right now that I'm aware of is they sent two items over. One is we had to alter the wall to go out of, and make sure we didn't go into a wetland. And so the noise wall had to be altered and all they're waiting on now, we've got it basically out of their clear zone of the road but all they're waiting now is just a small cross section drawing which I thought we'd actually have today but should have in the next few days. They actually have approved the location of the wall but the, they want to see a cross section of how the new wall, it's got a part, it's got a bumper rail on it because it got too close, it's not very close to the road but because the grade tips down we had to put a bumper on it so they're just waiting to see that cross section and then we should be good to go. Mayor Furlong: Good. John Knoblauch: Any questions? Mayor Furlong: Thank you. Any questions for Mr. Knoblauch? No, very good. Thank you. John Knoblauch: Okay. Mayor Furlong: Bring it back to council for discussion then. Any thoughts? Comments? My understanding is that this has been a challenge for everybody involved and we knew that back when we dealt with this project or worked on it about a year or so ago with the location of the freeway and the wetlands and all the other issues taking place. It's quite a challenge so I'd like to thank everybody from Mr. Knoblauch and staff for working together and finding a solution here so that what appears to be a very nice development can go forward. So with that if there are no other comments, we have a couple motions. I think we can take these as a single motion, unless there's any objections so we have motion 14 ..t Chanhassen City Council — July 28, 2014 1(a) and then I (b). Or excuse me, yep. Items I (a) and 1(b). Would anybody like to make a motion? Mr. Laufenburger. Councilman Laufenburger: Thank you Mr. Mayor. I move that the Chanhassen City Council grants approval for 1(a), final plat for Preserve at Rice Lake as shown on the plans dated Received June 13, 2014 and subject to the conditions of approval in the staff report, and that we grant approval for 1(b). Development contract, drainage utility easement, trail easement and construction plans and specifications for Preserve at Rice Lake conditioned upon the applicant supplying the City with a cash escrow or letter of credit for $1,113,979.19 and pay a cash fee of $183,479.13. Councilwoman Ernst: Second. Mayor Furlong: Nobody should accuse as of not being precise. Is there any discussion to the motion? Thank you for the second so quickly. Any discussions to the motion? Seeing none we'll proceed with the vote. Councilman Laufenburger moved, Councilwoman Ernst seconded that the Chanhassen City Council grants final plat approval of Planning Case #2013-12 for Preserve at Rice Lake to subdivide 13.22 acres into 16 lots and 2 outlots as shown in plans dated Received June 13, 2014, subject to the following conditions: Planning Department Conditions All lots must comply with the following table: COMPLIANCE TABLE 15 Area Width Depth Maximum (square feet) (feet) (feet)Hardcover Notes (square feet 60 at PUD 10,000 building 100 30 percent setback Ll Bl 10,085 129 122 3,025 Wetland L2 Bl 10,001 90 108 3,000 Wetland L3 Bl 11,324 152 109 3,397 Wetland L4 Bl 10,281 76 143 3,084 Wetland L5 Bl 10,103 70 146 3,031 L6 Bl 10,301 63 134 3,090 L7 Bl 10,017 62 128 3,005 L8 Bl 10,000 62 128 3,000 Wetland L9 Bl 10,187 62 129 3,056 Wetland L10 Bl 10,024 63 123 3,007 Wetland Lll Bl 12,083 65 (building 116 3,625 Wetland setback L12 BI 10,017 65 (building 118 3,005 Wetland setback 108 (building Wetland, * area of neck Ll B2 14,085* setback) 132 4,225 (4,961 sq. ft.) excluded from lot area calculations L2 B2 10,781 91 106 3,234 Corner lot 15 Chanhassen City Council — July 28, 2014 Wetland setback: 20 -foot buffer, 30 -foot principal structure, 15 -foot accessory structure.

Advanced warning and speed advisory signs are required where the design speed is less than 30 mph. 2. The site plan and HydroCAD model must be revised to address the following comments: a. Peak discharge rates are proposed to increase at the following locations: i. Runoff leaving the western portion of Wetland A for the 2, 10 and 100 year design events. ii. Runoff leaving the site to the north of the eastern portion of Wetland A for the snowmelt event. iii. Runoff leaving the site to the north of the western portion of Wetland A for all events. b. The applicant must provide calculations (or submit a model) demonstrating that the city's requirements for water quality are satisfied. 3. The developer shall replace the 18" culvert north of the site with a new pipe that provides the same capacity. 4. The lowest floor elevation of Lots 1 and 2, Block 1 need to be adjusted to maintain three feet of separation from the groundwater. 5. If groundwater is encountered during site construction the lowest floor elevations must be adjusted so that there is a minimum three-foot separation. 6. The developer must acquire any necessary permits from MnDOT for grading or drainage. 7. It is difficult to discern between the proposed contours, lot lines and setback lines. The developer's engineer is requested to change the drawing line weights. 8. Some homes may choose to install a privately -owned and maintained booster to provide a higher water pressure. 9. The owner of Lot 11, Block 1, Preserve at Rice Lake must be recorded in favor of 8591 Tigua Lane to allow for the water service installation. This easement shall be recorded with the final plat. 10. An Encroachment Agreement shall be recorded against Lot 11, Block 1, and Outlot A, Preserve at Rice Lake with the final plat to allow for the private water service to 8591 Tigua Lane. 11. Final Plat approval is contingent upon filing the drainage and utility easement on the property to the north, 8591 Tigua Lane. 12. A portion of the trunk sewer and water hookup fees (WAC and SAC, respectively) must be paid in cash with the final plat: WAC 16 units x $1,886/unit = $30,176 SAC 16 units x $664/unit = $10,624 The remainder of the WAC and SAC fees and the MCES SAC fee shall be paid with the building permit application at the rate in effect at that time. 17 Chanhassen City Council — July 28, 2014 13. The proposed location of the catch basin on the east side of the cul de sac must be shifted so that it will not conflict with the pedestrian ramp to the trail between Lots 11 and 12, Block 1. 14. The Agreement between the City and MnDOT to allow for the construction of the noise wall within MnDOT right of way must be executed before the final plat is recorded. 15. A trail easement between Lots 11 and 12, Block 1, must be filed with the final plat. 16. The applicant must apply for and receive an NPDES permit from the Minnesota Pollution Control Agency and provide evidence to the city prior to grading the site. 17. The following changes need to be incorporated into the SWPPP before any site grading can occur: a. The sheet labeled Appendix C-1: Erosion and Sediment Control Plan shall show erosion control blanket covering the disturbed areas adjacent to the road crossing the wetland and above the 894' contour for the most southwesterly pond. b. All erosion control blanket except in the overland emergency overflow areas shall either be netting free or use jute netting or another biodegradable material approved by the City. c. Topsoil shall be stripped and stockpiled in a berm on the up -gradient side of the silt fence. This shall be indicated on Appendix C-1: Erosion and Sediment Control Plan. d. Sheets LA and L-2 shall be added to the SWPPP after Appendix C-2 as these are part of the Final Stabilization Plan for the site. Water Resources Coordinator Conditions 1.

Furlong, Mayor (Published in the Chanhassen Villager on December 18, 2014) ?aax"wc Cr e,�r, �.cC 1 Graham Environmental Services, Inc. CI7YOFCHANHASSEN RECEIVED APR 19 2013 Nk%`HA"IP{/6tlfiIRyBwi f Chanhassen Site Wetland Delineation Report May 24, 2011 Looking West Across the Site From Wetland C Wetland Delineation Report Chanhassen Site Chanhassen, Minnesota May 24, 2011 Background Graham Environmental Services, Inc. (GES) was retained to complete a site evaluation for jurisdictional wetlands on a parcel located in part of the NW'/4 NE'/4 and part of the NE'/4 NSW'/4 of Section 24, T1 16N, R23W, Carver County. The site lies immediately north of Highway 212 and south of W. 86th Street in the City of Chanhassen (Figure 1). As shown on the U.S.G.S. Quadrangle map (Figure 2), the topography on the site is rolling. On April 28 and May 4, 2011, GES conducted an evaluation of the site and delineated five wetlands within the project vicinity as shown on a recent aerial photograph in Figure 3. Methodologies The site was assessed for wetlands using the on-site methods contained in the "Routine Determinations" section of the U.S. Army Corps of Engineers "Wetlands Delineation Manual' (Technical Report Y-87-1, 1987), as well as "Interim Regional Supplement to the Corps of Engineers Wetlands Delineation Manual: Midwest Region" (U.S. Army Corps of Engineers, 2010). This is the methodology currently used to determine wetlands by the U.S. Army Corps of Engineers for implementation of Section 404 of the Clean Water Act and by Local Government Units under the Wetland Conservation Act. GES classified the wetlands under the U.S. Fish and Wildlife Service (FWS) Cowardin system, Circular 39 and Eggers and Reed methodologies. Soil colors described herein follow Munsell Soil Color Charts. Hydric soil properties described follow Field Indicators of Hydric Soils in the United States (Untied States Department of Agriculture, Natural Resources Conservation Service. 2010. Field Indicators of Hydric Soils in the United States, Version 7.0. L.M. Vasilias, G.W. Hurt and C.V. Noble (eds.). USDA, NRCS, in cooperation with the National Technical Committee for Hydric Soils). Wetland Delineation Report Chanhassen Site — Chanhassen, MN May 24, 2011 Page 2 of 7 Results GES identified five wetlands within the property boundaries as discussed below. Wetland A Wetland A is located across much of the northern portion of the site. The wetland is bounded by relatively gradual grades on all sides except the west which is defined by a constructed berm. The upland/wetland boundary was investigated along a single transect on the southern boundary. A drainage ditch drains the wetland and flows to the east. Dominant vegetation in the wetland includes reed canary grass (Phalaris arundinacea) and sandbar willow (Salix interior). Upland vegetation is dominated by Kentucky bluegrass (Poa pratensis) and Canada goldenrod (Solidago canadensis). Soils were evaluated by digging soil pits along a transect perpendicular to the wetland/upland boundary and examining the profile's texture, color, and redoximorphic characteristics. Soils in the wetland in Transect 1 are described as 10 YR 3/2 loam over 10YR 5/1 silt loam with 10YR 4/6 mottles over 10YR 3/1 silt loam with 10YR 4/6 mottles over N 2/0 silt loam. Surface water measured approximately three inches in depth. Upland soils at Transect 1 are described as 10YR 3/2 sandy loam over 10YR 4/3 sandy loam. No free water or saturation was observed in the upland soil pit. The jurisdictional boundary was established where the soil profile in the upland soils demonstrates a lighter matrix tone, there is a change in plant communities, hydrology indicators are absent in the upland and a change in topography occurs. The National Wetlands Inventory map (Figure 4) is generally consistent with our wetland delineation. Like the NWI, we would classify the wetland as seasonally flooded palustrine emergent drained (PEMCd) under the Cowardin system which would equate to Type 3 inland shallow fresh marsh under the Circular 39 system and Shallow Marsh (1313) under the Eggers and Reed system. The Carver County Soil Survey (Figure 5) shows the soils in the vicinity of Wetland A to be Glencoe clay loam and Hamel loam. The Minnesota Department of Natural Resources Protected Waters Inventory (Figure 6) does not map Wetland A as a protected water or wetland.

Dominant vegetation in the wetland includes box elder (Acer negundo), green ash (Fraxinus pennsylvanica), common buckthorn (Rhamnus cathartica) and lake sedge (Carex lacustris). Dominant upland vegetation includes green ash and Kentucky bluegrass. Soils were evaluated by digging soil pits along a transect perpendicular to the wetland/upland boundary and examining the profile's texture, color, and redoximorphic characteristics. Soils in the wetland are described as 10YR 2/1 silt loam over 10YR 5/1 clay loam. Surface water was estimated to be approximately two inches in depth. Upland soils at Transect 1 are described as 10YR 3/2 silt loam. No free water or saturation was observed in the upland soil pit. The jurisdictional boundary was established where the soil profile in the upland soils demonstrates a lighter matrix tone, there is a change in plant communities, hydrology indicators are absent in the upland and a relatively abrupt change in topography occurs. The National Wetlands Inventory map (Figure 4) is generally consistent with our wetland delineation. Like the NWI, we would classify the wetland as seasonally flooded palustrine emergent (PEMC) under the Cowardin system which would equate to Type 3 inland shallow fresh marsh under the Circular 39 system and Shallow Marsh (136) under the Eggers and Reed system. The Carver County Soil Survey (Figure 5) shows the soils in the vicinity of Wetland B Transect 1 to be Hamel loam. The Minnesota Department of Natural Resources Protected Waters Inventory (Figure 6) does not map Wetland B. Wetland C Wetland C is a small wetland in the southeastern part of the site. Dominant vegetation in the wetland includes reed canary grass. Upland vegetation is dominated by green ash, smooth brome (Bromus inermis) and Canada goldenrod. Soils were evaluated by digging soil pits along a transect perpendicular to the wetland/upland boundary and examining the profile's texture, color, and redoximorphic characteristics. Soils in the wetland are described as 10YR 2/1 silt loam with 10YR 4/6 mottles over N 2/0 silt loam over 10YR 4/1 clay loam with 10YR 4/6 mottles. Surface water was estimated to be Wetland Delineation Report Chanhassen Site — Chanhassen, MN May 24, 2011 Page 4 of 7 approximately two inches in depth. Upland soils at Transect 1 are described as 10YR 3/2 silt loam over N 2/0 silt loam. No free water or saturation was observed in the upland soil pit. The jurisdictional boundary was established where the soil profile in the upland soils demonstrates a lighter matrix tone, there is a change in plant communities, hydrology indicators are absent in the upland and a change in topography occurs. The National Wetlands Inventory map (Figure 4) is generally consistent with our wetland delineation. We would classify the wetland as saturated palustrine emergent drained (PEMBd) under the Cowardin system which would equate to Type 2 inland fresh meadow under the Circular 39 system and Fresh (Wet) Meadow (156) under the Eggers and Reed system. The Carver County Soil Survey (Figure 5) shows the soils in the vicinity of Wetland C Transect 1 to be Hamel loam. The Minnesota Department of Natural Resources Protected Waters Inventory (Figure 6) does not map Wetland C. Wetland D Wetland D is a small wetland in the southern part of the site which drains to Wetland C via a shallow, excavated drainageway. Dominant vegetation in the wetland includes reed canary grass, box elder and staghorn sumac (Rhus hirta). Upland vegetation is dominated by staghorn sumac, smooth brome and Kentucky bluegrass (Poa pratensis). Soils were evaluated by digging soil pits along a transect perpendicular to the wetland/upland boundary and examining the profile's texture, color, and redoximorphic characteristics. Soils in the wetland are described as 10YR 3/1 silt loam with 10YR 4/6 mottles over 10YR 4/2 silt loam with 10YR 4/6 mottles over 10YR 5/1 silt loam with 10YR 4/6 mottles. Free water was observed approximately eight inches below the surface in the wetland soil pit. Upland soils at Transect 1 are described as 10YR 3/2 silt loam over 10YR 4/2 silt loam with 10YR 4/6 mottles. No free water or saturation was observed in the upland soil pit. The jurisdictional boundary was established where the soil profile in the upland soils demonstrates a lighter matrix tone, there is a change in plant communities, hydrology indicators are absent in the upland and a change in topography occurs. The National Wetlands Inventory map (Figure 4) is generally consistent with our wetland delineation. We would classify the wetland as saturated Wetland Delineation Report Chanhassen Site — Chanhassen, MN May 24, 2011 Page 5 of 7 palustrine emergent drained (PEMBd) under the Cowardin system which would equate to Type 2 inland fresh meadow under the Circular 39 system and Fresh (Wet) Meadow (15B) under the Eggers and Reed system. The Carver County Soil Survey (Figure 5) shows the soils in the vicinity of Wetland D Transect 1 to be Hamel loam. The Minnesota Department of Natural Resources Protected Waters Inventory (Figure 6) does not map Wetland D. Wetland E Wetland E is a very small wetland in the northwestern part of the site. The wetland appears to have been historically connected to Wetland A but is not separated by an upland berm. Dominant vegetation in the wetland includes American elm (Ulmus americana), eastern cottonwood (Populus deltoides), and box elder. Upland vegetation is dominated by box elder and common buckthorn. Soils were evaluated by digging soil pits along a transect perpendicular to the wetland/upland boundary and examining the profile's texture, color, and redoximorphic characteristics. Soils in the wetland are described as 10YR 2/1 silt loam over 10YR 4/1 silt loam with 10YR 4/6 mottles. Surface water was estimated to be approximately two inches in depth. Upland soils at Transect 1 are described as 10YR 2/1 silt loam over 10YR 5/4 clay loam fill. No free water or saturation was observed in the upland soil pit. The jurisdictional boundary was established where the soil profile in the upland soils demonstrates a lighter matrix tone, there is a change in plant communities, hydrology indicators are absent in the upland and a change in topography occurs. The National Wetlands Inventory map (Figure 4) does not appear to map Wetland E. We would classify the wetland as saturated palustrine deciduous forested (PF01 B) under the Cowardin system which would equate to Type 1 lowland hardwoods under the Circular 39 system and floodplain forest (3A) under the Eggers and Reed system. The Carver County Soil Survey (Figure 5) shows the soils in the vicinity of Wetland E Transect 1 to be Hamel loam. The Minnesota Department of Natural Resources Protected Waters Inventory (Figure 6) does not map Wetland E. Wetland Delineation Report Chanhassen Site — Chanhassen, MN May 24, 2011 Page 6 of 7 Ground photos of each wetland are included in Figures 7 — 11. Detailed information regarding each wetland's vegetation, soils and hydrology is included in the attached data forms (Appendix A). Regulatory Jurisdiction Minnesota DNR Public Waters The Minnesota DNR Protected Waters and Wetlands inventory (Figure 6) does not map any protected waters or wetlands within the site. The Minnesota DNR is represented on the Wetland Conservation Act Technical Evaluation Panel and, as such, would have input regarding any WCA actions on the on-site wetlands. Minnesota Wetland Conservation Act The jurisdictional wetlands that were identified on the subject parcel are subject to the Wetland Conservation Act Rules Chapter 8420. Under these rules, an approved replacement plan is required for activities that would fill or drain wetlands. Federal Regulatory Jurisdiction Several of the wetlands on the site appear to have surficial hydrologic connections to federal navigable waters. Therefore, we would anticipate that these basins are within the jurisdictional reach of the Corps of Engineers under Section 404 of the Clean Water Act. We would recommend obtaining a jurisdictional finding from the Corps prior to commencement of any activities near the wetlands. Delineation Concurrence Concurrence with our findings should be obtained from the U.S. Army Corps of Engineers (if they assert jurisdiction) and City of Chanhassen before any earthwork is undertaken which could affect the delineated wetlands or other waters on the site. Wetland Delineation Report Chanhassen Site — Chanhassen, MN May 24, 2011 Page 7 of 7 The information contained herein represents our findings during wetland delineation activities conducted on April 28 and May 4, 2011 at the referenced site.

I am concerned about what will happen to the pond area and the tree line between my place and this area. There is a lot of wildlife in this area and do not want this to be affected. Also this will decrease the value of my home. The reason I bought this place was because it backed up to a natural area. We CAN NOT destroy these areas.

Box 147 Chanhassen, MN 55317 RECEIVED SEP 1 G 2.013 CITY OF CHANHASSEN RE: City of Chanhassen Preserve at Rice Lake Comprehensive Plan Amendment - Administrative Review Metropolitan Council Review File No. 20265-6 Metropolitan Council District No 4 Dear Mr. Generous: The Metropolitan Council received the City's Preserve at Rice Lake plan amendment on August 23, 2013. The amendment reguides 13.23 acres from Residential Low Density to Residential Low and Medium Density. The subject property is located north of Highway 212 and southeast of the intersection of West 86th Street and Tigua Lane. The purpose of the amendment is to allow dual guiding of property to accommodate a 16 -unit detached housing development. Council staff finds the amendment meets the Comprehensive Plan Amendment Administrative Review Guidelines adopted by the Council on July 28, 2010. The proposed amendment does not affect official forecasts or the City's ability to accommodate its share of the region's affordable housing need. Therefore, the Council will waive farther review and action; and the City may place this amendment into effect. Staff also offers the following advisory comment: The Council encourages efforts to promote the efficient use of water to protect and enhance the region's water supply sources. New development and redevelopment always provide opportunities to implement new water conservation and stormwater management strategies as part of construction and site landscaping. The Council's Conservation Toolbox and Stormwater Reuse Guide may be useful tools to reduce per capita water demand. Both can be found on the Council's Water Supply Planning website at http://www.metrocouncil.org(Wastewater- Water/Plannin ater-Supply-Planning/Guidance-and-Planning-Tools aspx. The amendment, explanatory materials, and the information submission form will be appended to the City's Plan in the Council's files. If you have any questions please contact Angela R.

Sincerely, Sharmeen AI- & Senior Planner 952.227.1134 From: K B rmailto:kabll(o)msn.com] Sent: Monday, January 07, 2013 7:37 PM To: AI-Jaff, Sharmeen Subject: RE: development of area 5 of 86th st Hi, I looked at the plans. Why destroy part of the wetland area by putting a road thru it, what if that pond flooded, there is no other way out. Wouldn't a better plan be to put the road across from from lot 6 and 7, shorter road to development it doesn't destroy a good piece of the wetland. It doesn't impact our neighborhood, although traffic would increase along 86th st plus it would then cost less. Leave the wetland area alone. Another point to make would be the noise from 212. I hear traffic from my place, there is no noise reduction wall along this section, there's only a fence, that would have to be built. I would never buy anything in that area because of that. When I purchased my townhouse, I paid at least $5-6,000 more for the exact layout as another in this area because of the wooded area behind it. Like I said this will decrease the value of our property along Rice Court. Plus I like the privacy here as do my neighbors. We enjoy watching the wildlife. I have lived here since these townhomes have been built because of this, almost 17 yrs. There have been too many areas in Chanhassen that have been clear cut , beautiful old trees cut down. This needs to stop, We need to protect these areas.

Mr. John Knoblauch The Preserve at Rice Lake — Planning Case 2013-12 August 14, 2013 Page 3 Advanced warning and speed advisory signs are required where the design speed is less than 30 mph. 4. The site plan and HydroCAD model must be revised to address the following comments: a. Peak discharge rates are proposed to increase at the following locations: i. Runoff leaving the overall site for the snowmelt events. ii. Runoff leaving the western portion of Wetland A for the 2, 10 and 100 year design events. iii. Runoff leaving the site to the north of the eastern portion of Wetland A for the snowmelt event. iv. Runoff leaving the site to the north of the western portion of Wetland A for all events. b. The drainage areas and/or curve number in the HydroCAD model must correspond to the Drainage Area and Curve Number Table. c. Directly connected impervious areas must be modeled separately rather than included in the composite Curve Number computation. d. The applicant must provide calculations (or submit a model) demonstrating that the city's requirements for water quality are satisfied. i. If the event -based NURP standard cannot be achieved by dead pool storage, then (P8 or other) calculations should be based on equivalent annual removal efficiencies. ii. If an iron -enhanced filtration system is included in the design, calculations should be provided demonstrating the water quality treatment benefits of the BMP. Detailed plans of the system should be submitted for review with the calculations. iii. The report notes that the east pond is able to remove 87.8% of the phosphorus load. This removal efficiency appears excessively high. It is anticipated that there is either an error with the model inputs or the calculation was performed for a particular rainfall event rather than annualized removal efficiency. 5. The developer shall obtain off-site easements over the existing swale and 18" culvert. 6. The developer agreed to replace the 18" culvert north of the site with a new pipe that provides the same capacity. 7. The HydroCAD model must be revised so that the impervious surface of the lots is 30%. 8. If groundwater is encountered during site construction the lowest floor elevations must be adjusted so that there is a minimum three-foot separation. Mr. John Knoblauch The Preserve at Rice Lake — Planning Case 2013-12 August 14, 2013 Page 4 9. The grading plan must be revised to address the following comments: a. The developer must obtain a MnDOT permit for the proposed grading within the MnDOT right-of-way. b. It is difficult to discern between the proposed contours, lot lines and setback lines. The developer's engineer is requested to change the drawing line weights. 10. Some homes may choose to install a privately -owned and maintained booster to provide a higher water pressure. 11. The watermain shall be 8 -inch PVC (C-900). 12. Prior to final submittal the developer must obtain all necessary easements to install the sanitary sewer off-site, to the north. 13. A portion of the trunk sewer and water hookup fees must be paid in cash with the final plat in the rate in effect at that time. 14. The proposed location of the catch basin on the east side of the cul de sac must be shifted so that it will not conflict with the pedestrian ramp to the trail between Lots 11 and 12, Block 1. 15. Street and utility plan and profile construction plans must be submitted with the final plat. 16. Outfalls into the easterly pond must be minimized to the greatest extent practicable. 17. Plan shall show proposed pond maintenance access and landscaping must not interfere with pond maintenance access. 18. The applicant must apply for and receive an NPDES permit from the Minnesota Pollution Control Agency and provide evidence to the city prior to grading the site. 19. The Surface Water Pollution Prevention Plan (SWPPP) must be prepared as a standalone document and submitted to engineering for review and comment prior to final plat approval. This SWPPP shall include a narrative, plan set and applicable details. 20. The SWPPP must include the required elements as listed in Part III of the National Pollution Discharge Elimination System General Permit Authorization to Discharge Stormwater Associated with Construction Activity (NPDES Construction Permit) and in the MPCA SWPPP checklist. 21. A detailed erosion prevention and sediment control plan must be submitted for review and approval per the requirements of Section 19-145 of Chanhassen City Code and the NPDES Construction Permit. This should include, among the other listed requirements, all temporary and permanent best management practices. Mr. John Knoblauch The Preserve at Rice Lake — Planning Case 2013-12 August 14, 2013 Page 5 22. There is significant evidence of gully erosion at both off-site discharge locations. Rates must be reduced below existing discharge rates or efforts must be taken to stabilize these discharge points to prevent further channel incision and head cutting. 23. Wetland buffers are required around all wetlands on site. Extend buffer around wetland E. 24. Wetland buffer must be extended through all disturbed areas. A detailed vegetation management plan must be developed showing how these areas will be permanently stabilized. 25. A vegetation establishment and management plan must be developed and submitted for review for all areas preserved as open space including those areas graded for the construction of stormwater management practices and the installation of utilities that are above the normal water level prior to final plat approval. 26. Minnesota Department of Transportation right-of-way is outside of the City of Chanhassen's WCA jurisdiction as MnDOT is their own LGU. Chanhassen's review of wetland boundaries ended at the property limits. The applicant must get all appropriate approvals from MnDOT for work on the sound wall. 27. The development must comply with the MN Rules Chapter 6120 and the DNR must issue their concurrence to this effect. 28. Estimated Surface Water Management Connection charges due at the time of final plat are $69,983.50.

INC: REQUEST FOR A LAND USE MAP AMENDMENT FROM RESIDENTIAL -LOW DENSITY TO RESIDENTIAL -LOW AND MEDIUM DENSITY: REZONING FROM SINGLE-FAMILY RESIDENTIAL (RSF) AND MIXED LOW DENSITY RESIDENTUL (R4) TO PLANNED UNrr DEVELOPMENT- RESIDENTUL (PUD -R): PRELIMINARY PLAT OF 13.22 ACRES INTO 16 LOTS AND 2 OUTLOTS WITH VARIANCES; SITE PLAN REVIEW; AND WETLAND ALTERATION PERMIT. Kate Aanenson: Thank you Mayor, members of the City Council. This item also was heard by the Planning Commission on July 16m and they did recommend approval. The subject location is actually at the end of West 86d'Street, abutting against 212. The existing condition of the site is, it's encumbered by a wetland. It's actually in shoreland district of Rice Marsh Lake which I'll show in a little bit more detail. There's 13 acres of wetland. We did talk about this in the concept, when this came in because it was a little bit problematic to try to get the lot sizes to work on there so we actually up zoned this property. In an up zoning we still had to maintain the 4 units an acre and you'll see how that plays out as we move through the design of the project itself. So as I mentioned it's in the shoreland district, so you can see the different tiers of the shoreland district where it has different requirements for building within, lot size requirements so again in order to accomplish what the developer wanted to do, we had to go to the medium density allowed the small lot sizes and allowed some flexibility within the shoreland district requirements. So anything within that 1,000 square feet, even if it's a portion of a lot falls within the shoreland district. So as I stated the existing land use was low density and the zoning then was RSF and R-4 which did allow the 15,000 square foot lots or for the twinhomes also in the R4. So to accomplish again what the developer wanted to do, we have to do an up zone to get to the medium density so this application, as you just stated Mayor, includes a land use amendment, a rezoning, a subdivision, variance, 27 SCANNED Chanhassen City Council —August 12, 2013 site plan approval and a wetland alteration permit. So what we'll be doing then is actually changing the land use to the medium density and then the rezoning would then be for the PUD so again this is an item that would have to go up to the Met Council then for approval, just as you did tonight approving the apartment ones. This will have to go through that same process. So the proposed rezoning as I stated would then be to the PUD. So the PUD in looking at what the, in order to accomplish the goals of the developer then would be to give the setback variance from Highway 212. We have a longer cul-de-sac length. Reduced front and side yard setbacks. Reduced road width right -0f --way. A 10,000 square foot lot minimum. A 60 foot lot width. 100 foot lot depth and then a 30% hard surface coverage. Elimination of a sidewalk and so the developer would get enhanced, provide enhanced environmental features and then the sound wall along 212 would also then be constructed tying into the Mission Hills subdivision sound wall. Mayor Furlong: Ms. Aanenson, real quick question if you go back up to that slide. While it calls for a 60 foot lot width and 100 foot lot depth, that's only 6,000 square feet. Kate Aanenson: That's the minimums. They will be 10,000 square foot minimum lot size. Mayor Furlong: Okay, so the lot size would say, there would be no 60 by 100? Kate Aanenson: I'll spend a little bit, no there will not. The house plans will not fit on there and I'll show a little bit more in detail on that and that's part of the attributes that we put into the PUD ordinance to make sure all the houses that were proposed fit on the lots. Mayor Furlong: Thank you. Kate Aanenson: So then this would become then the PUD standards looking again what the developer wanted to do so we have the setback from the 212. We have perimeter setbacks. Front yard setbacks. The 25 feet. Then we have a 5 and a 10 which we've done in some of the other RLM districts. Minimum 15 but some at 5 and a 10. The rear yard allowing some 15 foot for accessory structures. Then each individual lot be at 30%. Some more detail was actually put to that, in that 30% calculated the different house plans and how they fit on each lot so that was the one issue that we want to make sure it's clear to the developer that not all the house plans presented will fit on all the lots so we want to make sure that the buyers going into this type of a home, the square footage and the type of home that these are, understand that there's limited ability to add to these lots. For example we calculated typically what the driveway hard cover, because the proposal that was put in by the applicant just included the square footage of the home so we also have to add for the driveway hard cover and then a back patio or something like that so those were all contributed to, or added to, to get to what we believe is a reasonable use so taking the minimum 10,000 square foot lot. Mayor, that's where that comes in. So that would be the minimum. And then the minimum 60 foot so some of these may be narrow but then they would be deeper so that kind of goes into how those different house plans fit on those lots. So then this then becomes the ordinance that we would be adopting with this. So the subdivision itself includes the 12 lots and, excuse me. 16 lots. Yeah, 16 single family lots and then the long cul-de-sac which was the variance. Then there were some other impacts to the wetland but I'm going to turn some of the specific environmental features over to the city engineer, but these would be the lots themselves and the orange is actually showing the trail that would connect down to the trail that we'll be discussing later tonight. But on the typical setbacks again I just want to show this illustratively how we looked at that. Giving the variance on the 25 foot front yard, and this is a building envelope and I would say that none of those lots out there are perfect squares. They're all different shapes but this is illustratively how it would look. So within that we identified which houses could fit on each and those were shown in your civil plans that were included in the packet. The different types of houses that would go on those lots. Again we've used this before and then this would, this is what was shown in your packet, the different style homes. Again I just want to 28 Chanhassen City Council — August 12, 2013 point out that those square footage that were shown on there do not include what we added for a driveway and then for additional hard cover so we've identified which houses would go on each lot and those again would be part of the requirements so we just want to make sure that the buyer going in there isn't thinking that they have the ability to add a big addition on in the future because there isn't that much room on these lots to accomplish that. So with that I'll turn it over to the city engineer to kind of go through some of the engineering issues. Paul Oehme: Thank you Ms. Aanenson. Noise wall will be required by the developer to be constructed for this development to meet the PCA requirements for residential homes. The proposed noise wall will be consistent or similar to what's currently out there today basically on the west property line. It's a wood, timber noise wall constructed with the 212 project. The noise wall would be built on an existing berm that is currently along the south edge of the property which is in MnDOT right-of-way. The City would have to enter into a cooperative agreement with MnDOT for construction and future maintenance of this wall, consistent with the walls that were constructed with the 212 project so. As Ms. Aanenson had indicated, the wetlands on this parcel are significant. About 27% of the property is encumbered by wetlands. We have worked with the developer to try to minimize the amount of impacts to the wetlands as much as we can. The impacts currently that only exist for this plan are circled here in the yellow. Those wetlands would be mitigated, either on site or through a bank process. The City has worked again with the developer on profiles of the roadway too to try to minimize the impacts to this, to the wetlands as well. Drainage for this development is probably one of the most challenging that we've worked on in the last couple of years here. With the wetlands in the area, the lack of city infrastructure to facilitate the storm water conveyance system on and off the property, but we did come up with I think a workable plan at this time. A majority of the current runoff does head to the, or a large portion of the property currently heads off to the east to the MnDOT property at this location. With the proposed development a lot more of the surface runoff will be heading north to a, through private property. Through a culvert that is in disrepair and across another property and then down to Rice Marsh Lake eventually so there are two storm sewer ponds proposed for this development. Infiltration basin and again we are trying to work around the wishes of the developer and try to limit the amount of impacts to this area as much as we can. Storm water. So one of the conditions that is in your packet for consideration is to obtain that storm sewer easement through the property just adjacent to the north there to fix the culvert that's currently in disrepair. So with that, moving on to ground water. Staff did work with a developer on taking piezometer readings or water table readings in this area. As we had indicated there's lot of wetlands out here. High water tables so we were concerned about what the finished floor elevations would be in relation to the ground water to meet our 3 foot minimum separation requirement. As indicated again the developer has raised the road up and some of the lots in this area to try to accommodate the high water tables in this area. It is our proposal that if, when the buildings are being excavated, the footings established, that the building officials look at you know where the water tables at that current time and potentially make adjustments to those final grades if necessary. With that. Kate Aanenson: With that we'd be happy to answer any questions that you would have on the project itself. Mayor Furlong: Alright, thank you for the report. Questions for staff. Councilman McDonald: I've got just one question. You had mentioned during the presentation that you know the buyers of the home would be informed that you know they're not going to be able to add a lot because, add additional features to the home. How are we going to do that because we've had trouble before in other areas of the city and getting that word across. Kate Aanenson: That's a challenge. If you look at the house plans that are on here, these are very nice homes on lots that you know can accommodate the houses but not a lot of extra so we were hoping that 29 Chanhassen City Council —August 12, 2013 certainly the developer, the builder would communicate that well, as we would on the permit when they come through and that's the best thing that we can do to try to communicate that. Not all of the applicants look at the builders but we try to communicate to them. Councilman McDonald: Okay, thank you Mayor Furlong: Other questions. Ms. Aanenson, there were modifications to this plan that's before us this evening since we saw it in concept and also since the Planning Commission. Could you just summarize for us those changes. Kate Aanenson: I believe the. Mayor Furlong: At least since the Planning Commission if we can't compare it to the concept. Kate Aanenson: Yes. This is probably the best one to look at. There was actually a sidewalk proposed on the site that I think was causing a lot of consternation of access to that. Because of the length of the cul-de-sac and the actual maintenance, when you get up into this area as you're not going past any houses and the fact that it may not be maintained, we decided to eliminate that sidewalk so that would be one of the biggest changes. I think some of the. Paul Oehme: The trail location Kate Aanenson: The trail, yes. Sorry, the trail location. That moved too and I think that's probably more illustratively at this one too. Mayor Furlong: Okay. Kate Aanenson: So again there is a long list of things that need to be done yet before this project go forward the least of which needs to be the Comp Plan amendment to accomplish this goal and then just all the other permitting things. There's, the developer has some work to do just kind of crossing the t's, dotting the I's to make this go forward so, it can be accomplished but. Todd Gerhardt: Over 42? Kate Aanenson: I think so. I think we beat that one. Mayor Furlong: Is there, the variance relates to the length of the street being proposed, the cul-de-sac, is that correct? Kate Aanenson: Correct. Mayor Furlong: Is there a reasonable way to service this property without doing that? Kate Aanenson: No, we looked at, you've got a single property owner to the north you know and so it would be problematic. Those are long, large lots but they're going to have trail on the back sides of those so there really is no good way to service those. Again looking at the density, we think that it should be okay. Mayor Furlong: Okay, so it's not just a preference to design it this way. There really is no reasonable 30 Chanhassen City Council —August 12, 2013 Kate Aanenson: Correct. If there was another reasonable way then we would certainly have tried to make that happen. Mayor Furlong: Okay. Alright, thank you. Any other questions for staff? Is the applicant here this evening? Mr. Knoblauch, if you'd like to address the council. Good evening. John Knoblauch: Good evening council, Mayor. I'm John Knoblauch, 1450 Knob Hill Lane, Chanhassen. I'm developer and builder of, working on the Preserve with staff here. Just a couple comments. The, unfortunately this drawing I kind of giggle about. There's actually only, if you look at the actual standing water is really only where that Outlot A is. The other wetlands are seasonal wetlands. C and D on the south end. There's also a wetland, a significant wetland on the east side right at the MnDOT property on the east side. Just a mention on the borings that were done. We've been watching the piezometer readings for ground water. 14 and 7 have shown higher levels than any of the other piezometers that have been on site. Fortunately 1 through 12 are all full walkout lots. At least proposed full walkouts. Typically when I build houses, full walkouts are not as likely to have water issues as a lookout or a full basement so I believe with exterior drain tiling, interior drain tiling, I don't see any issues there on those lots. We have raised 4 of the lots to make dang sure that we got the 3 foot ground separation right now and we did test right after our, I think we had a 4 inch and then we had 5 1/2 in 3 days and we did test right after that too so we're pretty comfortable with our ground water information that we have at this point. The only wetland impact, or the only wetland alteration is the road entry. We've moved the cul-de-sac to the north to avoid any impact at all that, so really it's just basically to access the property we literally have to impact that wetland on the west side. The sound wall that is proposed, we're working with Shirley Walker who is the engineer who did the wall on the, she did the 3,000 foot wall on the townhome site and so she is very good at what she does and she's working with ITCO to finish the wall design, which actually we did get a final plan today on that and that will be submitted to MnDOT shortly. I believe this week. One of our disappointing things with MnDOT right now is that they reneged on allowing us to landscape the north side of the berms that are there. I would hopefiilly encourage Jill Sinclair, the City Forester to, I would ask them to try to reconsider to allow us to put some plantings. We had a number of plantings we wanted to move on site. There's about 60 cedar trees that we'd like to save that are anywhere from 6 to 10 feet and I was going to hire a tree mover to save those and put them on the berm. Instead we had to kind of incorporate them in the rest of the project but we would like to landscape the berms if we could get MnDOT to agree to that but I don't know how hopeful that is. As far as the single family lots that are proposed here, I just think it's a very good use for the site. Twinhomes, townhomes, you know more pressure in this area. This is a dead end area. The acreage site to the north are bigger lots. You've got Mission Hills with nice homes. You've got the townhomes there. This is a good use of this parcel. As far as the 10,000 square foot lots, I've been building in Shakopee for about 22 years now. We're very accustomed to 10,000 square foot lots. We build mostly in Shakopee from 8,800 to 10,000. They actually don't have, one subdivision we were in there is 400 lots and there was nothing over 11,000 square feet so we're very comfortable building in this square footage. These lots are, the pad areas are 55 to 60 and will support a decent three car garage. I believe our drawings show a 30 foot 3 car. A lot of the national builders build 28 foot 3 cars so we definitely feel there's adequate space on all these lots and they do vary a little bit and we'll bring in some different architecture if we, on the different type of lots that are there. There's some longer ones up front there that will be real nice homes. We'll be able to show a lot of house on those instead of garage, which a lot of folks don't like as much garage to see so. You know as far as you know Chanhassen is concerned, the neighbors are definitely in favor of this. It really more was a twinhome site but with the lack of single family lots we feel this would be a great time for this project to move forward. Any questions? Mayor Furlong: Questions for Mr. Knoblauch? No. Thank you. 31 Chanhassen City Council — August 12, 2013 John Knoblauch: Yep Mayor Furlong: Comments or questions for staff. Okay, let's bring it to council for discussion. Thoughts and comments. Mr. Laufenburger. Councilman Laufenburger: Yeah, no questions but I just, my observations are that staff and Mr. Knoblauch have worked very hard to prepare this property for what I think will be a very, very good addition for homes and I just think it's going to be wonderful. I'm assuming Mr. Oehme that that cul-de- sac is going to have a large enough range so that you could turn around an emergency vehicle or anything like that. Paul Oehme: That's correct. It will be our standard cul-de-sac diameter. Councilman Laufenburger: Yeah, I think it's just going to be wonderful and certainly the noise wall will be necessary. I was going to ask Mr. Knoblauch, is that berm, is the berm, is it cyclone fence across the top of the berm right now? John Knoblauch: There's just a regular 6 foot chain link. Councilman Laufenburger: Chain link fence, okay. John Knoblauch: It's now a black chain link that I think was provided originally by MnDOT. Councilman Laufenburger: And you would replace that with a noise wall, is that correct? John Knoblauch: Yeah, that's correct. Varies from. Mayor Furlong: Mr. Knoblauch, if you could come up to the microphone for people watching at home. John Knoblauch: Yeah, the noise wall, the plan that's proposed right now varies on the west berm it's 8 foot tall which puts the height of it at 926 elevation and right at this point it actually goes up 2 feet from the 7 foot off the townhome wall and you know the nice thing about that is right now the homes, if they don't get any higher, that's why we don't, I don't want the homes to get too high because right now on the first I think 8 lots, if they were two story style homes the upper windows wouldn't he able to see over the wall and that'd be a nice feature for those folks. And this will he a huge help for the townhomes that get a little bit of noise from, coming from the east to the west. I think that's where there's going to be a huge benefit. We're also closing up, a lot of people call it the hole but we're closing up the hole with about a 20 foot wall between the two berms and that's where we seem to get a lot of noise kind of shooting through there. We think that's going to be a huge benefit. You know as far as to the east, the trail's really going to be a big plus for a lot of the folks. You know I can see some folks making a nice loop off that trail, looping back around. I think Todd would refer to that more later but the Mission Hills folks will have a really nice, about a mile loop to make to get, from their homes to go around. I think it's going to be a huge benefit for everybody involved over there. Councilman Laufenburger: Well let me just continue. Thank you Mr. Knoblauch. My observations are that you've done a good job to prepare this and thought of everything and looks like the adjustments that you've made have been very accommodating so I think this is a good project. Look forward to it. John Knoblauch: Thank you. 32 Chanhassen City Council — August 12, 2013 Mayor Furlong: Good. Thank you. Any other comments? Ms. Aanenson, if I could follow up, or Mr. Oehme. One of the two. One of the comments that Mr. Knoblauch made, and I forgot to ask questions when I asked if there were any questions and that relates to the plantings that he wanted to do on the, I guess north side of the wall. Is that strictly a MnDOT? Kate Aanenson: Yes. We worked, if you go, the one on Lakeside that was also adjacent to, we actually changed our PUD standards on that because we had a greater setback and we said why are we setting this so back, far back from the wall if they landscape it so we were able to work with that. It really comes down to, they want the City in the first position. We don't necessarily want to be in the first position on some of that responsibility so it's just something. Mayor Furlong: First position with regards to? Kate Aanenson: They would transfer the ownership to the City to maintain that and we would want to transfer it to the HOA so those are some of the concerns we just need to work through. Mayor Furlong: So it's the maintenance of the landscaping? Kate Aanenson: Yes. Mayor Furlong: Okay. So if I understand, MnDOT's willing to allow it if the City takes responsibility for it? Paul Oehme: I have not had that conversation with MnDOT but I'm assuming that's what they've said in the past. Typically they don't like to enter into agreements with thud parties, developers, HOA's. They like to deal with the cities directly so we can make calls to MnDOT and see if they'd be willing to work with us on additional plantings out there. Kate Aanenson: Yeah we'll work, similar to what we did on the other one. We'll see where it goes. Mayor Furlong: Thank you. Sony for that interruption. Comments from the council. Other comments? No, Mr. Laufenburger I think said it well and recognized the hard work on both the part of Mr. Knoblauch and the staff. I know this has been many meetings and many people have been involved trying to do what's best for this site and this looks like a very good result from that and so I think for all the reasons that were stated tonight and considered the last time this came forward through the Planning Commission and council, I think it's a good project and deserves our support. If there are no other comments, would somebody be interested in making a motion? Mr. Laufenburger. Councilman Laufenburger: Thank you Mr. Mayor. Mr, Mayor I move that the Chanhassen City Council approves the Land Use Map Amendment from Residential Low Density to Residential Low and Medium Density, rezoning from Single Family Residential (RSF) and Mixed Low Density Residential (R4) to Planned Unit Development -Residential (PUD -R), subdivision of the 13.22 acres into 16 lots and 2 outlots with variances, site plan review and wetland alteration permit subject to the conditions of the staff report and adoption of the attached Findings of Fact. Mayor Furlong: Thank you. Oh, Mr. Gerhardt? Todd Gerhardt: Just one modification to that. Instead of subdivision can you replace that with Preliminary Plat? Councilman Laufenburger: So moved 33 Chanhassen City Council — August 12, 2013 Mayor Furlong: So replace? Todd Gerhardt: Subdivision of 13.22 acres. Mayor Furlong: It would be. Todd Gerhardt: Preliminary Plat of 13.22 acres Mayor Furlong: Okay, thank you. The motion's been made with a substitution or the alternate language suggested by Mr. Gerhardt. Is there a second? Councilwoman Ernst: Second. Mayor Furlong: Thank you. Motion's been made and seconded. Any discussion? Seeing none we'll proceed with the vote. Resolution #201340: Councilman Laufenburger moved, Councilwoman Ernst seconded that the City Council approve the land use map amendment from Residential — Low Density to Residential — Low and Medium Density with the following condition, and adoption of the attached Findings of Fact and Recommendation: 1.

All relocated trees shall be warranted for two seasons and replaced by developer if dead or dying within that time period. Advanced warning and speed advisory signs are required where the design speed is less than 30 mph. 4. The site plan and HydroCAD model must be revised to address the following comments: a. Peak discharge rates are proposed to increase at the following locations: i. Runoff leaving the overall site for the snowmelt events. ii. Runoff leaving the western portion of Wetland A for the 2, 10 and 100 year design events. iii. Runoff leaving the site to the north of the eastern portion of Wetland A for the snowmelt event. iv. Runoff leaving the site to the north of the western portion of Wetland A for all events. b. The drainage areas and/or curve number in the HydroCAD model must correspond to the Drainage Area and Curve Number Table. c. Directly connected impervious areas must be modeled separately rather than included in the composite Curve Number computation. d. The applicant must provide calculations (or submit a model) demonstrating that the city's requirements for water quality are satisfied. i. If the event -based NURP standard cannot be achieved by dead pool storage, then (P8 or other) calculations should be based on equivalent annual removal efficiencies. ii. If an iron -enhanced filtration system is included in the design, calculations should be provided demonstrating the water quality treatment benefits of the BMP. Detailed plans of the system should be submitted for review with the calculations. iii. The report notes that the east pond is able to remove 87.8% of the phosphorus load. This removal efficiency appears excessively high. It is anticipated that there is either an error with the model inputs or the calculation was performed for a particular rainfall event rather than annualized removal efficiency. 5. The developer shall obtain off-site easements over the existing swale and 18" culvert. 6. The developer agreed to replace the 18" culvert north of the site with a new pipe that provides the same capacity. 36 Chanhassen City Council — August 12, 2013 7. The HydroCAD model must be revised so that the impervious surface of the lots is 30%. 8. If groundwater is encountered during site construction the lowest floor elevations must be adjusted so that there is a minimum three-foot separation. 9. The grading plan must be revised to address the following comments: a. The developer must obtain a MnDOT permit for the proposed grading within the MnDOT right-of-way. b. It is difficult to discern between the proposed contours, lot lines and setback lines. The developer's engineer is requested to change the drawing line weights. 10. Some homes may choose to install a privately -owned and maintained booster to provide a higher water pressure. 11. The watermain shall be 8 -inch PVC (C-900). 12. Prior to final submittal the developer must obtain all necessary easements to install the sanitary sewer off-site, to the north. 13. A portion of the trunk sewer and water hookup fees must be paid in cash with the final plat in the rate in effect at that time. 14. The proposed location of the catch basin on the east side of the cul de sac must be shifted so that it will not conflict with the pedestrian ramp to the trail between Lots 11 and 12, Block 1. 15. Street and utility plan and profile construction plans must be submitted with the final plat. 16. Outfalls into the easterly pond must be minimized to the greatest extent practicable. 17. Plan shall show proposed pond maintenance access and landscaping must not interfere with pond maintenance access. 18. The applicant must apply for and receive an NPDES permit from the Minnesota Pollution Control Agency and provide evidence to the city prior to grading the site. 19. The Surface Water Pollution Prevention Plan (SWPPP) must be prepared as a standalone document and submitted to engineering for review and comment prior to final plat approval. This SWPPP shall include a narrative, plan set and applicable details. 20. The SWPPP must include the required elements as listed in Part III of the National Pollution Discharge Elimination System General Permit Authorization to Discharge Stormwater Associated with Construction Activity (NPDES Construction Permit) and in the MPCA SWPPP checklist. 21. A detailed erosion prevention and sediment control plan must be submitted for review and approval per the requirements of Section 19-145 of Chanhassen City Code and the NPDES 37 Chanhassen City Council — August 12, 2013 Construction Permit. This should include, among the other listed requirements, all temporary and permanent best management practices. 22. There is significant evidence of gully erosion at both off-site discharge locations. Rates must be reduced below existing discharge rates or efforts must be taken to stabilize these discharge points to prevent further channel incision and head cutting. 23. Wetland buffers are required around all wetlands on site. Extend buffer around wetland E. 24. Wetland buffer must be extended through all disturbed areas. A detailed vegetation management plan must be developed showing how these areas will be permanently stabilized. 25. A vegetation establishment and management plan must be developed and submitted for review for all areas preserved as open space including those areas graded for the construction of stormwater management practices and the installation of utilities that are above the normal water level prior to final plat approval. 26. Minnesota Department of Transportation right-of-way is outside of the City of Chanhassen's WCA jurisdiction as MnDOT is their own LGU. Chanhassen's review of wetland boundaries ended at the property limits. The applicant must get all appropriate approvals from MnDOT for work on the sound wall. 27. The development must comply with the MN Rules Chapter 6120 and the DNR must issue their concurrence to this effect. 28. Estimated Surface Water Management Connection charges due at the time of final plat are $69,983.50. Provide area of wetland buffer and preservation/volume reduction area after development to accurately calculate credit. 29. Fifty -percent (50%) of park fees shall be collected in consideration for the dedication of Outlots A and B. The park fees shall be collected in full at the rate in force upon final plat submission and approval. At today's rate these fees would total $46,400 (16 lots X $5,800 per lot/2). 30. Wetland nomenclature on plan set shall be amended to correspond with HydroCAD drainage report and wetland replacement application. 31. The land owner and the selected contractor must provide a Landowner Statement and Contractor Responsibility for Work in Wetlands or Public Waters form to the City prior to working on the road crossing into the site. This form is available on the Board of Soil and Water Resources website. 32. A detailed planting schedule and maintenance plan must be provided for the preservation/volume reduction area. 33. Preservation/volume reduction area shall be protected from construction traffic, material stockpiling and other construction related activities during site development. These protection measures shall be shown in plans. 38 Chanhassen City Council —August 12, 2013 34. Signs shall be placed along the preservation/volume reduction area to protect the area from encroachment after build out. 35. Seeded areas within the outlots shall be established and managed according to guidelines and policies developed by the Minnesota Board of Soil and Water Resources as are available on their website. 36. Construction of the 8 -foot wide neighborhood trail connection from the public street to the southeast comer of the property. 37. The applicant shall comply with all MnDOT requirements for any work within their right-of- way, i.e. noise wall, landscaping, etc. All voted in favor and the motion carried unanimously with a vote of 5 to 0. Councilman Laufenburger moved, Councilwoman Ernst seconded that the City Council approve the Variances to allow a reduced setback from Highway 212 and a cul-de-sac that exceeds 800 feet in length as shown in plans dated received August 5, 2013 with the following conditions and adoption of the attached Findings of Fact and Recommendation: 1. Approval of the variances is contingent upon approval of the Land Use Plan Amendment, Subdivision, Site Plan Review, Rezoning and Wetland Alteration Permit. All voted in favor and the motion carried unanimously with a vote of 5 to 0. Councilman Laufenburger moved, Councilwoman Ernst seconded that the City Council approve the site plan for a medium density development as shown in plans dated received August 5, 2013 with the following conditions and adoption of the attached Findings of Fact and Recommendation: 1. Approval of the Land Use Amendment subject the Metropolitan Council determination of consistency with system plan. 2. Adoption of the Chanhassen PUD Ordinance, which shall be created to govern the site and design standards. 3. Execution of the Site Plan Permit. 4. Approval of the final plat and execution of the development contract. All voted in favor and the motion carried unanimously with a vote of 5 to 0. Councilman Laufenburger moved, Councilwoman Ernst seconded that the City Council approve the wetland alteration permit as shown in plans dated received August 5, 2013 with the following conditions and adoption of the attached Findings of Fact and Recommendation: 39 Chanhassen City Council — August 12, 2013 1.

These signs shall be placed concurrent to the installation of erosion prevention and sediment control BMPs except when grading is proposed at a buffer monument location. 3. The plan must meet the sequencing requirements of the Minnesota Wetland Conservation Act. This can be accomplished by locating the sidewalk to the north side of the proposed road and extending the regional connection between lots 1 I and 12 of Block 1. 4. A completed Application for Withdrawal of Wetland Credits Form shall be provided with the Minnesota Local/State/Federal Application for Water/Wetland Projects as well as a signed and executed purchase agreement between the applicant and the bank holder. 5. Wetland nomenclature on plan set shall be amended to correspond with HydroCAD drainage report and wetland replacement application. 6. Approval of the Wetland Alteration Permit is contingent upon approval of the Land Use Plan Amendment, variances, Rezoning, Site Plan Review, Final Plat, and execution of the Development Contract. All voted in favor and the motion carried unanimously with a vote of 5 to 0. Mayor Furlong: Thank you very much everyone. Appreciate your continued hard work. Let's move now to the next item on our agenda. RICE MARSH LAKE TRAIL IMPROVEMENTS: CONSIDER AWARD OF BID. Todd Hoffman: Thank you Mayor, members of the council. Tonight we bring you good news on two separate park projects. The first being the Rice Marsh Lake trail. The photo we see there is the current connection point within the city of Eden Prairie. This is a bridge right down at Highway 212 within the city of Eden Prairie and this was the last segment that they completed two summers ago. Mayor Furlong: Is that a back of a sign that says. Todd Hoffman: Trail to be continued in the future. Mayor Furlong: Thank you. Todd Hoffinan: And the immediate segment coming directly at us will be another Eden Prairie segment of trail which they are currently under contract with, with another contractor and so both the City of Eden Prairie and the City of Chanhassen will be working simultaneously to complete these final segments of the Rice Marsh Lake trail, which when complete will be a 3 mile trail loop around Rice Marsh and will really just be one of the nicest trail experiences in the southwest metro, if not in the metropolitan area in it's entirety and so we're very happy about the bid award. So the City of Chanhassen project is to construct 4,200 feet of pedestrian trail and it starts at our current terminus point near Mission Hills Drive.

PROPOSAL/SUMMARY The request consists of multiple applications to facilitate the development of a 16 -lot subdivision to house detached homes: Land Use Map Amendment from Residential -Low Density to Residential -Low and Medium Density; Rezoning from Single Family Residential (RSF) and Mixed Low Density Residential (R4) to Planned Unit Development -Residential (PUD -R); Subdivision of 13.22 acres into 16 lots and 2 outlots with Variances; Site Plan Review; and Wetland Alteration Permit. The site is located north of Highway 212 and southeast of the intersection of West 86th Street and Tigua Lane. Planning Commission Preserve at Rice Lake — Planning Case 2013-12 July 16, 2013 Page 3 of 37 The property is currently zoned RSF — Single Family Residential District and Mixed Low Density Residential District. With the adoption of the 2030 Comprehensive Plan in 2008, the City Council guided the site Residential Low Density. The following is a summary of the requests: 1. Land Use Map Amendment: The first request is to amend the land use plan from Residential -Low Density to Residential -Low and Medium Density. 2. Rezoning: The second request is to rezone the property from Single Family Residential (RSF) and Mixed Low Density Residential (R4) to Planned Unit Development - Residential (PUD -R); and set standards that will govern the development. Since this land is within the shoreland district, the applicant is preserving 50% of the site as open space. 3. Subdivision: The third request is to subdivide 13.22 acres into 16 lots and 2 outlots. There is no minimum lot size in this district. The lot area ranges between 10,000 and 12,723 square feet. The maximum hard surface coverage permitted per lot may not exceed 30%. The applicant submitted a number of typical house designs he intends to build on the proposed lots. Some of the parcels are limited to a single design. A table that lists the maximum hard surface permitted per lot will be incorporated into the standards for this development. 4. Variance: The fourth request is to allow reduced setbacks from Highway 212 and length of a cul-de-sac. There will be a noise wall that will separate this development from the highway. City code requires a minimum setback of 50 feet along the perimeter of a planned unit development. The applicant is requesting a 30 -foot setback. Also, the proposed cul-de-sac is approximately 1,400 feet long, which exceeds the 800 -foot maximum length stipulated in the City Code. Based on the lot configuration and wetland conditions on the site, staff supports the proposed variance. 5. Site Plan Review: The fifth request is to approve a site plan for a medium density development. 6. Wetland Alteration Permit: The sixth request is to allow wetland impacts for the construction of a roadway and trails. Some of these impacts cannot be avoided while others can be avoided. Staff is recommending approval of the proposed development subject to the conditions of the staff report.

Planning Commission Preserve at Rice Lake — Planning Case 2013-12 July 16, 2013 Page 6 of 37 On February 11, 2013, City Council approved transmittal for jurisdictional review the land use amendment from Residential — Low Density to Residential — Low and Medium Density. The 60 - day review period ended April 13, 2012. There were no negative comments received. LAND USE MAP AMENDMENT The applicant is requesting a comprehensive plan land use map amendment from Residential — Low Density to Residential — Low and Medium Density. This land use will permit additional flexibility in the design and development of the site and is compatible with the surrounding land uses, which are guided Residential — Medium Density to the west, Residential — Low Density to the north, Parks and Open Space to the east and Highway 212 to the south. Existing Land Use APPLICABLE REGULATIONS Proposed Land Use The city is acting within its legislative capacity in making amendments to the comprehensive plan. As part of the process, the city will be making a policy decision. Approval of the development is contingent upon approval of land use amendment. ANALYSIS Part of the difficulty in developing this site are the wetlands that are located on the property, as well as its location within the Rice Marsh Lake Shoreland Overlay District. The site is accessible via 86`s Street/Tigua lane and would follow an old farm access road through the wetland complex. This type of land use, a mix of Residential Low and Medium Density, permits Planned Unit Developments with clustered homes and no minimum lot size. This will allow staff to work with the applicant to maximize preservation and enhancement of natural features. It also allows the city to determine the best type of housing development (attached versus detached housing). Planning Commission Preserve at Rice Lake — Planning Case 2013-12 July 16, 2013 Page 7 of 37 Existing Conditions The goal is to allow the development with minimum impact to the natural features of the site. Staff found that in this situation the application of standard Single Family Residential regulations would be impractical due to 1) the desire to build single-family detached homes on the site, 2) the presence of the 15,000 square -foot minimum lot size for non -riparian lots and 90 -foot frontage, and 3) wetlands. Staff finds that a preferred alternative to achieve this goal would be to guide the site Residential Medium Density. This category allows the clustering of homes with no minimum lot size or frontage. In this case, the homes will be placed in locations that will have the least impact on the natural features and will allow the applicant the opportunity to enhance the wetlands and surrounding buffer. At the same time, the developer would be able to build the single-family detached homes. The following elements of the comprehensive plan discuss land use policies that should be evaluated in changing the land use. Chanter 2 Land Use Element 2.5.2 Residential — low density The dominate type of development within the residential district is low-density, single-family detached housing. Net densities within this category range from 1.2 to 4.0 units per acre. For projection of land demand, an average density of two dwelling units per acre was used. There are several zoning applications within the low density including RSF (Residential Single Family), R- 4 (Mixed Low Density), RLM (Residential Low and Medium Density), and PUD -R (Planned Unit Development -Residential). Planning Commission Preserve at Rice Lake — Planning Case 2013-12 July 16, 2013 Page 8 of 37 2.5.3 Residential — Medium density The medium density designation is intended to accommodate multiple units including duplexes, townhouses and lower -density apartments or condominiums. A net density range of 4.0 — 8.0 units per acre is covered by this category with an expected density of 6.0 units per acre. The zoning options in the medium density land use include R4 (Mixed Low Density), RLM (Residential Low and Medium density), R-8 (Mixed Medium Density Residential) and PUD -R (Planned United Development -Residential). Medium density is viewed as transitional use between low density and Commercial, office or high-density areas. Comprehensive Plan Goals and Policies 4.6 Housing Goals and Policies Goals: Provide housing opportunities for all residents, consistent with the identified community goals: • A variety of housing types for all people in all stages of the life cycle. • A community of well-maintained housing and neighborhoods, including ownership and rental housing. • Housing development that respects the natural environment of the community while striving to accommodate the need for a variety of housing types and costs. • The availability of a full range of services and facilities for its residents, and the improvement of access to a linkage between housing and employment. • Housing development methods such as PUDs, cluster development, and innovative site plans and building types, should be encouraged to help conserve energy and resources for housing. REZONING Justification for Rezoning to PUD The applicant is requesting to rezone 13.23 acres from Single Family Residential (RSF) and Mixed Low Density Residential (R4) to Planned Unit Development -Residential (PUD -R). The project consists of 16 single-family homes. The review criteria are taken from the intent section of the PUD Ordinance. For a property guided Medium Density Residential, zoning consistent with the land use includes RLM, Residential Low and Medium Density District, R-8, Mixed Medium Density Residential District or PUD -R, Planned Unit Development — Residential. Since the developer wanted a development of single-family detached housing, the R-8 district did not work because it does not permit single-family detached homes. Initially, the developer tried to use the RLM district as well as the RSF district; however, due to site topography, shoreland overlay district and the location of wetlands, the developer could not meet the minimum standards for the lots and many lot width and area variances would have been required. Since the PUD -R district creates its own Planning Commission Preserve at Rice Lake — Planning Case 2013-12 July 16, 2013 Page 9 of 37 standards, we were able to accommodate the development while preserving significant environmental features. If the property was reguided to medium density residential, the developer must maintain a minimum density of 4.0 units per acre. As proposed, the net density of the project is 4.0 units per acre. Section 20-501. Intent Planned unit developments offer enhanced flexibility to develop a site through the relaxation of most normal zoning district standards. The use of the PUD in this instance is to allow for lot dimension flexibility. In exchange for this enhanced flexibility, the City has the expectation that the development plan will result in a significantly higher quality and more -sensitive proposal than would have been the case with the other more standard zoning districts. The proposed development provides a compatible development with the surrounding development and is consistent with the comprehensive plan subject to the conditions of approval. The proposed rezoning assists in the furtherance of the following land use goals of the City of Chanhassen Comprehensive Plan: • Development will be encouraged within the MUSA line. • The plan should seek to establish sufficient land to provide a full range of housing opportunities. • The city will seek opportunities to provide transitions between different uses of different types. • Development should be phased in accordance with the ability of the city to provide services. The proposed rezoning assist in the furtherance of the following housing goals of the City of Chanhassen Comprehensive Plan: • A balanced housing supply with housing available for people of all income levels. • A variety of housing types for people in all stages of the life -cycle. Housing development that respects the natural environment of the community while striving to accommodate the need for a variety of housing types and costs. Planning Commission Preserve at Rice Lake — Planning Case 2013-12 July 16, 2013 Page 10 of 37 Staff is proposing the following development standards govern the development of the property. DEVELOPMENT DESIGN STANDARDS PRESERVE AT RICE LAKE a. Intent The purpose of this zone is to create a PUD for a single-family detached development. The use of the PUD zone is to allow for more flexible design standards while creating a higher quality and more -sensitive proposal. The PUD requires that the development demonstrate a higher quality of architectural standards and site design. Except as modified by the Preserve at Rice Lake development standards, the development must comply with the Residential Low and Medium Density District, RLM. b. Permitted Uses The permitted uses in this zone shall be limited to single-family detached houses and their ancillary uses. The type of uses to be provided on common areas shall he low -intensity neighborhood - oriented accessory structures to meet daily needs of residents. Such uses may include development signage, garden, gazebo, maintenance shed, picnic shelter, permanent open space, playground equipment and trails. C. Setbacks The PUD ordinance requires setbacks from roadways and property lines. The following table displays those setbacks. *Lot coverage may not exceed those established in the compliance table.

The proposed subdivision makes adequate provision for water supply, storm drainage, sewage disposal, streets, erosion control and all other improvements required by this chapter; Finding: The proposed subdivision is served by adequate urban infrastructure. 5. The proposed subdivision will not cause environmental damage; Finding: The proposed subdivision will not cause significant environmental damage subject to conditions of approval. The proposed subdivision contains adequate open areas. 6. The proposed subdivision will not conflict with easements of record. Finding: The proposed subdivision will not conflict with existing easements, but rather will expand and provide all necessary easements. The proposed subdivision is not premature. A subdivision is premature if any of the following exists: a. Lack of adequate storm water drainage. b. Lack of adequate roads. C. Lack of adequate sanitary sewer systems. d. Lack of adequate off-site public improvements or support systems. Finding: The proposed subdivision will have access to public utilities and streets. VARIANCE The applicant is requesting a reduced setback from Highway 212. City Code requires all buildings to maintain a 50 -foot setback from arterial or collector streets. The reason behind the variance request is the fact that there will be a noise wall that will separate the subject site from the highway. The applicant is requesting structures maintain a 30 -foot setback from the north property line. The applicant is also requesting a variance for the length of the cul-de-sac serving the subject site and a reduced width of 28 feet for approximately 400 feet. City Code limits the length of a cul-de-sac to 800 feet. The proposed cul-de-sac is approximately 1,400 feet long, which exceeds the 800 -foot maximum length stipulated in the City Code. Based on the lot configuration and wetland conditions on the site, staff supports the proposed variance. Planning Commission Preserve at Rice Lake — Planning Case 2013-12 July 16, 2013 Page 15 of 37 The setback variance is addressed under City Code Chapter 20 -Zoning, Sec. 20-58. The variance for the length of the cul-de-sac is addressed under City Code Chapter 18 -Subdivisions, Sec. 18-22. Variance Findines — Setback. Chapter 20 Section 20-58 of the City Code provides the following criteria for the granting of a variance: a. Variances shall only be permitted when they are in harmony with the general purposes and intent of this Chapter and when the variances are consistent with the comprehensive plan. Finding: The 50 foot perimeter setback was established to separate potentially incompatible uses. In this area a noise wall will separate the uses. Additional setbacks are not necessary. b. When there are practical difficulties in complying with the zoning ordinance. "Practical difficulties," as used in connection with the granting of a variance, means that the property owner proposes to use the property in a reasonable manner not permitted by this Chapter. Practical difficulties include, but are not limited to, inadequate access to direct sunlight for solar energy systems. Finding: The wetlands on the property and the location of the Highway 212 right-of- way create a practical difficulty in locating houses at the 50 foot setback. In this area a noise wall will separate the uses. Additional setbacks are not necessary. c. That the purpose of the variation is not based upon economic considerations alone. Finding: The purpose of the variance is not based on economic considerations alone. The applicant is proposing to construct single-family home on residential property at a typical building setback. d. The plight of the landowner is due to circumstances unique to the property not created by the landowner. Finding: The alleged difficulty or hardship is not a self-created hardship. The wetlands on the property and the location of the Highway 212 right-of-way create unique circumstances for the placement of homes. e. The variance, if granted, will not alter the essential character of the locality. (Similar home sizes) Finding: The home will be located in the interior of the proposed development and will be compatible with the other homes. Planning Commission Preserve at Rice Lake — Planning Case 2013-12 July 16, 2013 Page 16 of 37 f. Variances shall be granted for earth sheltered construction as defined in Minnesota Statutes Section 216C.06, subdivision 14, when in harmony with this Chapter. Finding: This does not apply to this request. Variance Findings—Length of cul-de-sac, Chanter 18 Section 18-22 of the City Code provides the following criteria for granting a variance: The city council may grant a Variance from the regulations contained in this chapter as part of the plat approval process following a finding that all of the following conditions exist: a. The hardship is not a mere inconvenience; Finding: The hardship is not a mere inconvenience, but is due to the property being accessed from West 86`h Street and then meandering around the wetlands. No additional street access is available to the property due to the wetlands. b. The hardship is caused by the particular physical surroundings, shape or topographical conditions of the land; Finding: The hardship is caused by the particular physical surroundings, shape or topographical conditions of the land with wetlands located to the north, south and east and west of the site. c. The condition or conditions upon which the request is based are unique and not generally applicable to other property; Finding: The condition or conditions upon which the request is based are unique and not generally applicable to other property since it is located on property that is hemmed in by wetlands. d. The granting of a variance will not be substantially detrimental to the public welfare and is in accord with the purpose and intent of this chapter, the zoning ordinance and comprehensive plan. Finding: The granting of a variance will not be substantially detrimental to the public welfare and is in accord with the purpose and intent of the subdivision ordinance, the zoning ordinance and the comprehensive plan. SHORELAND REGULATIONS The site is located within the Rice Marsh Lake Shoreland Overlay District (area located within 1000 feet from the High Water Level of a lake) and is subject to the standards and requirements of the Department of Natural Resources (DNR) and City Code. The intent of the shoreland rules are to protect the habitat, viewscape and water quality of the waters of the state by setting design standards to this end. Planning Commission Preserve at Rice Lake — Planning Case 2013-12 July 16, 2013 Page 17 of 37 This property lies within the Shoreland Management District and is subject to the Planned Unit Development (PUD) requirements. The applicant must demonstrate that by granting the flexibility that comes with a PUD, enhancements are made that would not be seen with a straight single-family residential development plan. Given that wetlands are protected under Chanhassen City Code, the Minnesota Wetland Conservation Act, and in many instances the Federal Clean Water Act, the act of preserving wetlands is not a benefit that would not otherwise be realized. Further, the proposed buffer areas are the minimum required and would be the same with a straight subdivision. There is no enhancement being proposed. All stormwater management is contained within the outlot areas. This is standard practice. However, these Oudot areas are considered to be the 50% open space as required by the Shoreland PUD rules in their entirety despite the construction of structures. These ponds would be required under a straight subdivision as well. The creation of these ponds results in significant disturbance within the areas to be preserved as naturalized open space. It is imperative that seed mixes and species composition are suited to the site characteristics. These characteristics can differ markedly within a small distance as exposure, proximity to water features and soil characteristics change. The selection of one seed mix for all areas typically does not result in successful plant establishment, especially in the absence of a long-term management plan — typically three (3) to five (5) years. The MN/DOT seed mixes have been phased out and have been merged with the BWSR seed mixes. Seed mix 34-181 would be better suited to areas that are expected to receive periodic inundation such as the margin of the pond Normal Water Level and the edge of the wetlands. In the wetland buffer areas and the emergency overflow areas for the ponds, seed mix 34-262 or similar would be more likely to realize a successful establishment. The disturbed upland areas would be well suited to seed mix 35-241. The forb content of this last seed mix could be left out in those areas where extensive forestation is to occur.

Unlike single-family lots that fall within the shoreland district and are guided low density, there are no minimum lot widths or areas for medium density lots within a shoreland district. Other design standards apply to these lots as follows: The development must comply with the MN Rules Chapter 6120 and the DNR must issue their concurrence to this effect. An adequate stormwater management and erosion/sediment control plan must be provided. These will be addressed under a separate heading. DNR regulations (section 6120.3800, subp. 5. B. (2) (a)) require that "at least 50 percent of the total project area within the shoreland district, which extends 1,000 feet out from the edge of the lake, must be preserved as open space". The total area of the site is 13.23 acres. The applicant is proposing to maintain 57% of the site as open space which exceeds the DNR requirements. WETLAND PROTECTION Graham Environmental Services, Inc. (GES) performed an on-site wetland determination and boundary delineation on April 28 and May 4, 2011. This was reviewed by city staff as the local government unit (LGU) responsible for administration of the Wetland Conservation Act and submitted to the technical evaluation panel for comment. Based upon review of the delineation, the boundaries were approved excepting that Wetland C and Wetland D were determined to be part of the same basin and Wetland B was expanded to the north. The current plan submittal appears to accurately reflect these modified boundaries. The plan set was provided by Probe Engineering Company, Inc. on behalf of J&S Ventures. While is plan shows the required buffer around wetlands A through D but fails to show a buffer around wetland E. All wetlands, including wetland E, require the establishment of buffer areas and setbacks per Section 20-411 of Chanhassen City Code. Any wetland buffer areas that are disturbed do not meet the requirement for native vegetation as stated in §20-411, or which contains noxious weeds must have a detailed vegetation management plan and that plan must be followed. These areas must be identified as buffer on the plan. P, to show a buffer around wetland E.

Planning Commission Preserve at Rice Lake — Planning Case 2013-12 July 16, 2013 Page 19 of 37 The submitted plan defines the extent of three two impact areas. eW de --e `kthe- -s-'I. These impacts are a result of the proposed road alignment to access the property. The site is inaccessible without some wetland impact. The proposed road alignment does minimize the wetland impacts to the greatest extent practicable when considering road design standards and wetland configuration. Wetland buffer must be established on the side slopes of the road where it crosses the wetland. Section 20-401(b) reads that "The intent of this article is to avoid alteration and destruction of wetlands. When this is not feasible, mitigation must be provided to recreate the function and value of the lost or altered wetlands." Section 20-410(b)(4) reads that "Ibe size of the altered area shall be limited to the minimum required for the proposed action." Minnesota Rules 8420 (the Minnesota Wetland Conservation Act) regulates the protection of wetlands within the state of Minnesota. Section 8420.520 SEQUENCING stipulates that an LGU "must not approve a wetland replacement plan unless the local government finds that the applicant has demonstrated that they have met the sequencing requirements of the Wetland Conservation Act." The first goal must always be to avoid a wetland impact. Minnesota Rules 8420.520 Subp. 3 C. reads as follows: (2) The local government unit must determine whether any proposed feasible and prudent alternatives are available that would avoid impacts to wetlands. An alternative is considered feasible and prudent if it meets all of the following requirements: (a) it is capable of being done from an engineering point of view; (b) it is in accordance with accepted engineering standards and practices; (c) it is consistent with reasonable requirements of the public health, safety, and welfare; (d) it is an environmentally preferable alternative based on a review of social, economic, and environmental impacts; and (e) it would create no truly unusual problems. Minnesota Rules 8420.0520 Subp. 3 C. goes on to say: (4) If the local government unit determines that a feasible and prudent alternative exists that would avoid impact to wetlands, it must deny the replacement plan.

Planning Commission Preserve at Rice Lake — Planning Case 2013-12 July 16, 2013 Page 22 of 37 DRAINAGE AND GRADING The developer hired Kallio Engineering to perform a hydrology analysis of the site. The study includes the off-site drainage from the west and north. Runoff from the eastern half of the street and the eastern lots is proposed to be treated in the proposed pond east of Lot 11, Block 1. A portion of the street is proposed to drain to the proposed pond in the southwest comer of the property. Runoff from the fust 230 feet of the proposed street south of the intersection with Tigua Lane is not proposed to be treated on-site. The developer's engineer that prepared the hydrology report has included this runoff in the analysis. The following comments pertain to the hydrology analysis provided by the developer: a. Peak discharge rates are proposed to increase at the following locations: 1. Runoff leaving the overall site for the 2 year (2.8"` and snowmelt events. 2. Runoff leaving the western portion of Wetland A the site for eaeh the 2, 10 and 100 year design events. 3. Runoff leaving the site to the north of the eastern portion of Wetland A for the snowmelt event. 4.

If the event -based NURP standard cannot be achieved by dead pool storage, then (P8 or other) calculations should be based on equivalent annual removal efficiencies. 2. If an iron -enhanced filtration system is included in the design, calculations should be provided demonstrating the water quality treatment benefits of the BMP. Detailed plans of the system should be submitted for review with the calculations. 3. The report notes that the east pond is able to remove 87.8% of the phosphorus load. This removal efficiency appears excessively high. It is anticipated that there is either an error with the model inputs or the calculation was performed for a particular rainfall event rather than annualized removal efficiency. The developer shall obtain off-site easements over the existing swale and 18 -inch culvert. The developer has agree to replace the 18 -inch culvert with a new pipe that provides the same capacity. The HydroCAD model assumed 3,500 sf of impervious surface on each lot, which averages 32% impervious surface over all lots. Article VIII Planned Unit Development, Section 20-505 of the City Code allows for 30% overall hard surface coverage of the lots within medium density residential developments. The HydroCAD model must be revised accordingly. Staff calculated that the minimum and maximum evemll impervious surface of each lot the 16 lots will be ° based on the house styles provided by the developer and the lot sizes proposed. The results are summarized below: Smallest Largest House House Lot Footprint Footprint 1 28.7% 28.7% 2 28.9% 30.2% 3 25.5% 29.9% 4 29.4% 29.4% 5 29.9% 29.9% 6 28.1% 29.3% 7 28.9% 28.9% 8 29.9% 28.9% 9 28.4% 29.7% 10 28.9% 28.9% 11 24% 26.5% 12 28.9% 31.4% Planning Commission Preserve at Rice Lake — Planning Case 2013-12 July 16, 2013 Page 24 of 37 Block 2 Smallest Largest House House FLot--1 Footprint Footprint 1 20.6% 22.7% 2 28.1% 29.2% 3 28.9% 28.9% 4 28.9% 28.9% As shown in the table, the proposed house for Lot 3, Block 1 exceeds the maximum allowable impervious surface. Also note that for some lots the largest home style noted on the plan exceeds the maximum allowable impervious surface. For the remainder, This calculation included one, 100 square foot landing and a five -foot -wide sidewalk from the driveway to the front door on each lot. This means there will be minimal opportunity for homeowners in the development to build patios, sport courts, or other amenities. Based on the submittal, the pond design does not provide additional storage to warrant impervious surface in excess of 30%. Additionally, the majority of patios, sport courts, etc. are constructed in the backyards. All backyards within Block 1 drain north and offsite, therefore increasing the allowable impervious surface in the backyards would further increase the peak discharge rates offsite and the downstream risks of erosion and localized flooding. Further, these backyard areas are immediately adjacent to an area that is intended to use vegetation management to reduce the volume of runoff. It has been staffs' experience that homeowners have a certain expectation for outdoor landscaping and other amenities and will often unwittingly encroach into undeveloped adjoining property. If this occurs, the volume reduction and rate control benefits of this area will be lost further increasing the rate and volume downstream and the subsequent risks. During pre -submittal meetings with the developer, city staff expressed concern of potential high groundwater elevations within the development. The developer responded by installing six piezometers on the site that allow for the measurement of static water pressures. Though groundwater was not encountered when soil borings were taken, groundwater is present in all piezometers. The developer provided the piezometer readings from May and June, 2013 which were unseasonably wet months. The lowest floor elevations shown on the grading plan provide three feet of separation from the highest readings. If groundwater is encountered during site construction, the lowest floor elevations must be adjusted so that there is minimum a three-foot separation. The highest recorded piezometer reading was 900.5 feet at B 14, installed between Lots 11 and 12, Block 1. Twelve feet (12') of cut is proposed at the storm water pond located 100 feet west of B 14. It is unknown if the groundwater will flow into the storm water pond. If it does, the removal efficiency may decrease and peak discharge rate out of the pond may increase.

ROADWAYS The property lies north of Highway 212, east of County Road 101 and south of West 86th Street. The proposed access on West 86th Street is located so as to minimize wetland impacts. To further reduce wetland impacts, staff supports a reduced right-of-way width (50 feet, with a 15 - foot front yard drainage and utility easement) and a reduced street width (28 feet) for the portion of the road that does not have any lots adjacent to it (approximately 400 feet). The remainder of the street and right-of-way shall meet the City s minimum requirements. The proposed street curves do not meet a 30 mph design speed; advanced warning and speed advisory signs would be required. The proposed cul-de-sac is approximately 1,400 feet long, which exceeds the 800 -foot maximum length stipulated in the City Code. Based on the lot configuration and wetland conditions on the site, staff supports the proposed variance. Planning Commission Preserve at Rice Lake— Planning Case 2013-12 July 16, 2013 Page 26 of 37 UTILITIES A 12 -inch trunk watermain extends from the townhome development to the west to the Reflections development south of Highway 212. The developer proposes to extend lateral watermain from this trunk line to service the development. Based on the proposed elevations of the homes, the operating water pressures within the homes will meet the minimum required per 10 States Standards; however, some homes may choose to install a privately -owned and maintained booster to provide a higher water pressure. The watermain shall be 8 -inch PVC (C-900). The developer proposes to extend lateral sanitary sewer from the existing 8 -inch lateral sanitary sewer north of the site. The developer is required to get the all necessary easements over the sanitary sewer pipe to complete this work prior to final plat submittal. Street and utility plan and profile construction plans must be submitted with the final plat. The proposed location of the catch basin on the east side of the cul de sac must be shifted so that it will not conflict with the pedestrian ramp to the trail between Lots 11 and 12, Block 1. A portion of the trunk sewer and water hookup fees must be paid in cash with the final plat in the rate in effect at that time. The property was assessed $8,700 for the 2006 Trunk Watermain Extension. This assessment was certified to Carver County property taxes; therefore, the final payment will be made with the second half taxes or when the property is final platted, whichever event takes place first.

This fee is broken into water quality and water quantity and is based upon net developable acreage and a multiplier intended to reflect the anticipated burden the land use will place upon the storm sewer system relative to other land uses. Credit is then given for storm water management best management practices at a rate of % the water quality rate per acre treated. The estimated total Storm Water Management Connection fee is 67,483.50. The following table shows the calculations. Buffer areas with proper demarcation, protection and vegetative management are deducted from the calculated area. Not only is the protection and enhancement of open space a necessary component of the PUD process, it serves as a financial incentive for proper protection and management. EROSION PREVENTION AND SEDIMENT CONTROL Peak discharge discharge rates are increased at both places where drainage will leave the site. In both instances the outlet channel has become incised and headcuts are forming within the _. channel. At the outfall downstream of the driveway, a surge basin was ;V ! installed at some point in the past. The channel has since worked around _ either side of the surge basin as illustrated in the photograph to the Y�• n } left. The other channel is incised. The depth of this incision will increase and will almost certainly accelerate as the discharge rate and, therefore, the scour force within the channel increases. In both instances, this channel discharges to Rice Marsh Lake and the resulting erosion will lead to increased sediment deposition into the Planning Commission Preserve at Rice Lake— Planning Case 2013-12 July 16, 2013 Page 28 of 37 lake. The shoreland PUD standards require that erosion control and storm water management facilities "be designed, and their construction managed, to minimize the likelihood of serious erosion occurring either during or after construction......" Efforts must be taken to reduce the rate of runoff or assure that the channels are stabilized to prevent further degradation. By procuring an easement over the existing 12" and 18" outlets and the accompanying channel, the liability of maintenance can be borne by the city rather than the private land owners to the north of the site which accept this discharge. The applicant must work with the landowner to procure an easement over this channel. The total disturbed area is unknown but is certainly greater than one acre in size. Given the total disturbance it must be compliant with the National Pollution Discharge Elimination System General Permit Authorization to Discharge Stormwater Associated with Construction Activity (NPDES Construction Permit). As part of this permit, the applicant is required to develop a Surface Water Pollution Prevention Plan (SWPPP) with three elements: a narrative, plan sheets and standard detail plates. Each of these elements requires specific content. Section 19-145 of Chanhassen City Code requires that the construction is compliant with the NPDES Construction Permit and the SWPPP is provided to the City for review and comment. The current submittal is lacking the majority of the required SWPPP content. There is no standalone erosion prevention and sediment control plan included in the plan set. The Minnesota Pollution Control Agency has developed a checklist to determine if the required content is included. Rather than enumerate the deficiencies, the applicant and their consultant are referred to this document, as well as and Part III, pages 6 —15 and Part IV of the NPDES Construction Permit.

As the new NPDES Construction Permit is now in force, the applicant must comply with the conditions set forth in that permit and provide the SWPPP for city review and approval prior to final plat approval. COMPREHENSIVE PARK PLAN The city's comprehensive park plan calls for a neighborhood park to be located within one-half mile of every residence in the city. The proposed Preserve at Rice Lake development would not meet this guideline. The nearest park is Rice Marsh Lake Park which is located approximately one mile away if utilizing the city's pedestrian trail network. COMPREHENSIVE TRAIL PLAN The city's comprehensive trail plan calls for the future completion of a Rice Marsh Lake Trail to be constructed around the perimeter of the lake. This proposed subdivision should provide for Planning Commission Preserve at Rice Lake — Planning Case 2013-12 July 16, 2013 Page 29 of 37 and construct a trail connection to this future trail starting at the public street and extending to the southeast corner of the property. This trail connection should be situated in a public outlot or trail easement. The developer- shall pay fW4 par4 fees in effeet at the fime ef final plat appr- LANDSCAPING AND TREE PRESERVATION The applicant has provided a tree inventory and removal plan for the subdivision. Bufferyard plantings are required for this development along Highway 212. Tree preservation calculations for the development are shown below. Total upland area (excluding wetlands) 413,111 SF or 9.48 ac. Total canopy area (excluding wetlands) 66,600 SF or 1.52 ac Baseline canopy coverage 16% Minimum canopy coverage allowed 25% or 103,277 SF Proposed tree preservation 4% or 16,820 SF The developer does not meet minimum canopy coverage allowed. Additional plantings will be required to bring the baseline canopy coverage up to the minimum required. Required plantings 87 trees (66600-16820)x1.2 54 trees required (103277-66600) 33 trees required The applicant has proposed 48 53 new trees and 30 44 transplanted evergreens in the landscape plan for a total of 97 trees. The applicant is required to provide bufferyards along Highway 212. The minimum plantings required and the applicant's proposed quantities are shown in the table below.

The following is a summary of the traffic noise assessment which was conducted by David Braslau Associates, Inc.: a. Traffic noise levels have been predicted for the Preserve at Rice Lake location north of TH 212 in Chanhassen, Minnesota. b. The analysis has been performed for 16 receptor locations both at the ground floor and upper or second -story level. c. A noise wall on top of the existing berms that will extend the existing noise wall to the west is proposed. d. The top of the wall elevation is 924 and the wall varies in height from 8 feet on the west to 10 feet on the east, with a higher wall between the berms and on the east end, where a short wrap-around wall is proposed. e. With the wall, all of the ground level receptors are predicted to be below the daytime L10 65 dBA standard for residential land uses. All second -story receptors are also predicted to be below the standard except the two closest, which are estimated to be only 2 dBA over the daytime standard. f. Nighttime (6-7 am) levels at all of the receptor sites are estimated to be over the L10 55 dBA standard. g. However, exceptions to the noise standards permit the NAC -2 or Commercial Noise Standard to be applied which is LI O 70 dBA, providing certain conditions are met. With appropriate home construction, these conditions should be met so that all receptor sites will be in compliance with the state noise standards. RECOMMENDATION A.

The applicant must provide calculations (or submit a model) demonstrating that the city's requirements for water quality are satisfied. i. If the event -based NURP standard cannot be achieved by dead pool storage, then (P8 or other) calculations should be based on equivalent annual removal efficiencies. ii. If an iron-enbanced filtration system is included in the design, calculations should be provided demonstrating the water quality treatment benefits of the BMP. Detailed plans of the system should be submitted for review with the calculations. iii. The report notes that the east pond is able to remove 87.8% of the phosphorus load. This removal efficiency appears excessively high. It is anticipated that there is either an error with the model inputs or the calculation was performed for a particular rainfall event rather than annualized removal efficiency. 7. The developer shall obtain off-site easements over the existing swale and 18" culvert. 8. The developer agreed to replace the 18" culvert north of the site with a new pipe that provides the same capacity. 9. The HydroCAD model must be revised so that the impervious surface of the lots is 30%. 10. If groundwater is encountered during site construction the lowest floor elevations must be adjusted so that there is a minimum three-foot separation. 11.

The Subdivision Ordinance directs the Planning Commission to consider seven possible adverse affects of the proposed subdivision. The seven (7) affects and our findings regarding them are: a. The proposed subdivision is consistent with the zoning ordinance; b. The proposed subdivision is consistent with all applicable city, county and regional plans including but not limited to the city s comprehensive plan; c. The physical characteristics of the site, including but not limited to topography, soils, vegetation, susceptibility to erosion and siltation, susceptibility to flooding, and storm water drainage are suitable for the proposed development; d. The proposed subdivision makes adequate provision for water supply, storm drainage, sewage disposal, streets, erosion control and all other improvements required by this chapter; e. The proposed subdivision will not cause environmental damage; f. The proposed subdivision will not conflict with easements of record; and g. The proposed subdivision is not premature. A subdivision is premature if any of the following exists: 1) Lack of adequate storm water drainage. 2) Lack of adequate roads. 3) Lack of adequate sanitary sewer systems. 4) Lack of adequate off-site public improvements or support systems. 6. The Zoning Ordinance directs the Planning Commission to consider the following when evaluation a Site Plan: a. The proposed site plan is consistent with the elements and objectives of the city's development guides, including the comprehensive plan, official road mapping, and other plans that may be adopted; b. The proposed development is consistent with the site plan review requirements of city code; c. The proposed site plan preserves a portion of the site in its natural state to the extent practicable by minimizing tree and soil removal; d. The proposed site plan creates a harmonious relationship of building and open space with natural site features and with existing and future buildings having a visual relationship to the development; e. The proposed site plan creates a functional and harmonious design for structures and site features, with special attention to the following: 1) An internal sense of order for the buildings and use on the site and provision of a desirable environment for occupants, visitors and general community; 2) The amount and location of open space and landscaping; 3) Materials, textures, colors and details of construction as an expression of the design concept and the compatibility of the same with adjacent and neighboring structures and uses; and 4) Vehicular and pedestrian circulation, including walkways, interior drives and parking in terms of location and number of access points to the public streets, width of interior drives and access points, general interior circulation, separation of pedestrian and vehicular traffic and arrangement and amount of parking. £ The proposed site plan protects adjacent and neighboring properties through reasonable provision for surface water drainage, sound and sight buffers, preservation of views, light and air and those aspects of design not adequately covered by other regulations which may have substantial effects on neighboring land uses. 7.

The proposed development will not be hazardous or disturbing to existing or planned neighboring uses. e. The proposed development will be served adequately by essential public facilities and services, including streets, police and fire protection, drainage structures, refuse disposal, water and sewer systems and schools; or will be served adequately by such facilities and services provided by the persons or agencies responsible for the establishment of the proposed use. f. The proposed development will not create excessive requirements for public facilities and services and will not be detrimental to the economic welfare of the community. g. The proposed development will not involve uses, activities, processes, materials, equipment and conditions of operation that will be detrimental to any persons, property or the general welfare because of excessive production of traffic, noise, smoke, fumes, glare, odors, rodents, or trash. h. The proposed development will have vehicular approaches to the property which do not create traffic congestion or interfere with traffic or surrounding public thoroughfares. i. The proposed development will not result in the destruction, loss or damage of solar access, natural, scenic or historic features of major significance. j. The proposed development will be aesthetically compatible with the area. k. The proposed development will not depreciate surrounding property values. 1. The proposed development will meet standards prescribed for certain uses as provided in the Conditional Use article. 8. Variance Findings — Section 20-58 of the City Code provides the following criteria for the granting of a variance: The fourth request is to allow reduced setbacks from Highway 212 and length of a cul-de-sac. There will be a noise wall that will separate this development from the highway. The City code requires a minimum setback of 50 feet along the parameter of a planned unit development. The applicant is requesting a 30 -foot setback. a. Variances shall only be permitted when they are in harmony with the general purposes and intent of this Chapter and when the variances are consistent with the comprehensive plan. Finding: The 50 -foot perimeter setback was established to separate potentially incompatible uses. In this area a noise wall will separate the uses. Additional setbacks are not necessary. b. When there are practical difficulties in complying with the zoning ordinance. "Practical difficulties," as used in connection with the granting of a variance, means that the property owner proposes to use the property in a reasonable manner not permitted by this Chapter. Practical difficulties include, but are not limited to, inadequate access to direct sunlight for solar energy systems. 4 Finding: The wetlands on the property and the location of the Highway 212 right-of- way create a practical difficulty in locating houses at the 50 -foot setback. In this area a noise wall will separate the uses. Additional setbacks are not necessary. c. That the purpose of the variation is not based upon economic considerations alone. Finding: The purpose of the variance is not based on economic considerations alone. The applicant is proposing to construct single-family home on residential property at a typical building setback. d. The plight of the landowner is due to circumstances unique to the property not created by the landowner. Finding: The alleged difficulty or hardship is not a self-created hardship. The wetlands on the property and the location of the Highway 212 right-of-way create unique circumstances for the placement of homes. e. The variance, if granted, will not alter the essential character of the locality. (Similar home sizes) Finding: The homes will be compatible with the surrounding area. f. Variances shall be granted for earth sheltered construction as defined in Minnesota Statutes Section 216C.06, subdivision 14, when in harmony with this Chapter. Finding: This does not apply to this request. 9. The city may grant a Variance from the regulations contained in the subdivision ordinance as part of the plat approval process following a finding that all of the following conditions exist: a. The hardship is not a mere inconvenience, but is due to the property being accessed from West 86th Street and then meandering around the wetlands. No additional street access is available to the property due to the wetlands; b. The hardship is caused by the particular physical surroundings, shape or topographical conditions of the land with wetlands located to the north, south and east and west of the site; c. The condition or conditions upon which the request is based are unique and not generally applicable to other property since it is located on property that is hemmed in by wetlands; d. The granting of a variance will not be substantially detrimental to the public welfare and is in accord with the purpose and intent of the subdivision ordinance, the zoning ordinance and the comprehensive plan. 10. The planning report #2013-12, dated July 16, 2013, prepared by Sharmeen AI-Jaff, et al, is incorporated herein.

It is located southeast of Tigua Lane and West 86`" Street, just north of Hwy 212. The property is 13.23 acres. We are requesting a re -zoning to a PUD. The site has 163,187 sq. ft. of delineated wetlands of which only 14,095 sq. ft. would be impacted. We are proposing to satisfy the 2:1 wetland mitigation requirements by purchasing wetland credits from a wetland bank. The development utilizes a portion of the upland arca to create 16 lots ranging in area from 10,004 to 18,303 Sq. Ft. The overall proposed density of the le'iots on 13.23 acres is 1.2 units per acre. This proposal leaves 3.65 acres of upland included open space. The proposed rezoning of the site is to a,PUD. The PUD designation is to allow for deviations from zoning requirements in order to provide a better development while being sensitive to the wetlands and working around the site constraints. The PUD process allows the City the flexibility to create better developments by deviation from standard zoning code requirements in exchange for the expectation that the development will result in better land use taking into account the environmental features of the property. Benefits to this PUD: r`1 Ys_ 1. The site is essentially clustered. This clustering allows for the creation and preservation of open�space within the subdivision. The development proposes to retain 57.2% open -space versus the 50% minimum required. With the application of clustering the lots, the natural features and beauty of the site can be preserved. This project will have the gross density is a 1.2 units per acre, and the average lot size will be '/4 acre. 2. The vast majority of the existing wetlands will remain untouched. The main impact is due to the necessity of the access road, without which the parcel could not be developed. All wetlands have appropriate buffer areas which will be contained within outlots to be deeded to the city. The developer will place a sign or post indicating conservation area at the rear lot comers of those lots abutting the wetland outlot. 3. Behind lots 4 thin 8, Block 1, between the minimum wetland buffer strip and the rear property lines, we are proposing to keep this area as an enhanced preservation area. This would effectively enlarge the buffer area and help filter the rear yard 4. 5. R I 0 runoff from the wetland. This would enhance and help protect the natural wetland beauty of the site. The developer is currently working with the adjacent land owner to the north in an effort to connect into sanitary sewer service via a manhole located on the landowner's lot. The original plan for this project called for connecting to a manhole approximate 200 feet north of the northeast corner of the property. This original plan would have required the removal of significantly more trees in this area, and would be a large impact to the high quality wetland on the east end of the parcel. We are also in discussions with this land owner to provide them a water service hook up to City water. Installation of a noise wall. As the developer we will be installing an extensive noise wall along Hwy 212 which will not only lessen the highway traffic noise for this property but for the adjacent properties as well. The wall will be constructed to match that of the adjacent existing wall. The wall will be constructed in the MnDOT right-of-way. MnDOT is aware of this proposal and is not opposed to the wall or plantings. Clustering the lots allows for reduced hard sw-ike area. While there are no individual lot hard surface requirements, the`calculations below demonstrate this claim. Street Pavement Area 43,183LS' Ft.. Sidewalk & Future Trail ilk 0,713 Sq. Driveway t Sq , (Est. 1,000 per lot) Bldgs, Porch, Patios etc. 4A'O(b' Ft. (Est. 2,500 per lot) i�Yd e i Total Hard Cover Is 109,896 Sq. Ft. (19.07%) We also are pfoposing additional treesoverand above what is minimally required. Minimally required are 87 trees and 46 shrubs. We are proposing planting 12 (13 % more) trcgs and 54 additional ornamental grasses. Added to the shrubs, this is a 117% increase. The trees and grasses will enhance the streetscape and provide a visuallypifying element. Mail Boxes. A custom designed mail box will be constructed. These will be grouped to minimize street impact and to comply with the US postal service requirements. Placement and design must have final approval by the post office prior to installation. Street Element Plantings. The additional Prairie Fire crabapple trees and Purple Foliage switch grass placed approximately every 50 feet along the main entrance and at the trailhead will help to make a unified appearance for the subdivision while helping to make a visual transition from the natural landscape to the urban maintained landscape. The plant materials are native in appearance but by using them often and in a uniform pattern, the image will be one of design and not random as in nature. 10. We are proposing a 5' wide sidewalk. This sidewalk will not only be used by the residents but we believe it will be mostly used by the surrounding neighborhood as access to the future park trail to the east. This side walk will make the pedestrian feel more like they are on a continuation of the park trail to the east, instead of walking through someone's front and side yards to get to the trail. Lastly, it should be a very safe trail to walk on because on the south side of the cul de sac there are only 3 driveways. 11. Staff is also asking that the trail extension be located between Lots 11 and 12 to avoid a small wetland impact. Doing this would not be a problem except that we feel that this route not only makes the pedestrian experience not as pleasant with less of a secluded walk, but it is also more intrusive for the adjacent residences. We feel the trail as shown allows a more open view public access while still protecting the adjacent resident's privacy. We also believe that the future trail can be constructed to rninimithe wetland impact. We will construct the sidewalk section within the right of way, and the rest is shown as future trail. It is our understanding that if we construct the sidewalk as shown on the plan then eventually the City Parks Department will construct tl trail portion from the cul de sac to the east, shown as future trail. fRc•, This property is both beautiful with its wetlands and natural areas, anoet has had many constraints that make it difficult to develop. This very beautiful singf� family development will provide the best situation for land use for this parcel, while still preserving a large portion for open space. This development also at the same time creates a buffering with the impact of the highway and mipimizing the impact to adjacent existing neighbors. We ask the City to approve this preliminary plat of The Preserve at Rice Lake so that this subdivision can and will be an amenity to the City of Chanhassen and the surrounding residentj~borhoods for many years to come.

Before any further development, please address the following issues: Proposed Noise Wall.- Consistent all.Consistent with MnDOT's May 5, 2008 letter to John Klingelhutz, MnDOT will "grant permission for the construction and placement of noise mitigation on MnDOT right-of- way with the following conditions: 1. All MnDOT construction specifications and requirements are met; 2. Submission of noise mitigation plans. The noise mitigation plans shall contain the necessary documentation showing the effectiveness of the mitigation (a.k.a. a. "Noise Study); 3. The noise mitigation plans meet MPCA standards for noise reduction; 4. The noise mitigation design is of the same nature, or consistent with, existing MnDOT noise mitigation in the vicinity; 5. All future maintenance and ownership agreements are in place; and 6. All Appropriate permits are acquired." The details concerning these six items will need to be addressed in a Cooperative Construction Agreement between the City of Chanhassen and MnDOT. For consistency with the noise wall to the west and to avoid confusion, MnDOT is willing to take over ownership of the wall following construction. Additionally, as is typical with new wall construction, MnDOT will address issues such as graffiti on the US 212 side and the City will need to address such issues on the portion of the wall facing away from US 212. Please note that permanent structures and landscaping will be prohibited on MnDOT right-of-way due to potential drainage issues. MnDOT is allowing the noise wall to be constructed on MnDOT property because of the unique circumstances associated with this development. Future noise walls built for development adjacent to US 212 will not be allowed on MnDOT right-of-way. To initiate the cooperative construction agreement, please contact MnDOT Metro District's Area Engineer, Diane Langenbach at 651-234-7721. Water Resources: A MnDOT drainage permit may be required. It is MnDOT s policy that current drainage rates to MnDOT right-of-way must not be increased. To determine if a drainage permit is needed, please provide a grading plan showing existing and proposed contours. Also provide drainage area maps for the proposed project showing existing and proposed drainage areas with flow directions indicated by arrows. This information should be submitted to: Hailu Shekur Water Resources Engineering 1500 West County Road B2 Roseville, MN 55113 If it is determined that the project does drain to Mn/DOT right-of-way, a drainage permit will be required to ensure that current drainage rates to Mn/DOT right-of-way will not be increased. The drainage permit application, including the information below, should be submitted to: Minnesota Department of Transportation Metropolitan District - Permit Office 1500 W. County Road B-2 Roseville, MN 55113 The following information must be submitted with the drainage permit application: 1) A grading plan showing existing and proposed contours, 2) Drainage area maps for the proposed project showing existing and proposed drainage areas. Any off-site areas that drain to the project area should also be included in the drainage area maps. The direction of flow for each drainage area must be indicated by arrows, 3) Drainage computations for pre and post construction conditions during the 2, 10, 50 and 100 year rain events, and 4) An electronic copy of any computer modeling used for the drainage computations.

John Knoblauch ��S Ur�Tt�/SiT-N'� APPLICATION FOR PUD REZONING & PRELIMINARY PLAT REVIEW Chanhassen City Staff Planning Department May 20, 2013 J & S Venturesl Inc. is proposing a 16 lot single family development called Preserve at Rice Lake. It is located southeast of Tigua Lane and West 86th Street, just north of Hwy 212. The Aacent property is developed as single family homes to the north and northeast and as townhomes to the west. The property is 13.23 acres and is currently zoned for townhomes. We are requesting a re -zoning to a PUD for single family homes. The PUD designation is to allow for deviations from zoning requirements in order to provide a better development while being sensitive to the wetlands and working around the site constraints. The PUD process allows the City the flexibility to create better developments by deviation from standard zoning code requirements in exchange for the expectation that the development will result in better land use taking into account the environmental features of the property. This parcel is not unusual but it does have some major physical constraints to work around. The site has 163,187 sq. ft. of delineated wetlands. It is also located between an existing highway, existing homes, and a wetland. The site was originally part of a tree farm and there are a few remaining trees along with many new volunteer growth cedars Great care has been given to the property and surrounding proWrties in designing this development. The development utilizes a portion of the upland area to create 16 lots ranging in area from 10,000 to 19,056 Sq. Ft. The overall proposed density of the 16 lots on 13.23 acres is 1.2 units per acre. The impact on the wetland is minimal. Only 12.252 N. ft. of the entire 163,187 N. ft. will be impacted. We are proposing to satisfy the 2:1 wetland mitigation requirements by purchasing wetland credits from a wetland bank. This proposal leaves 3.58 acres of upland included open space. One of the questions that staff has asked is how this development benefits the City and how does the reduction in code requirements make this a better development overall. We believe that the PUD not only allows creative use of the land but it provides for a better development in the following wa}_s. 1. The development design promotes site clustering. This clustering allows for the creation and preservation of open space within the subdivision. The development proposes to retain 57.2% open space versus the 50% minimum required. With the application of clustering the lots, the natural features and beauty of the site can be preserved. This project will have the gross density is a 1.2 units per acre, and the average lot size will be''/s acre. 2. With the reduction of density on the site, we believe there will also be the reduction in need for City services such as police, fire, and other emergency vehicles. 3. The length of the cul-de-sac is somewhat long compared to the number of homes it serves. By annroving single family homes for this pronertv it will also reduce traffic counts on the adiacent roadways. 4. The vast majority of the existing wetlands will remain untouched. The main impact is due to the necessity of the access road, without which the parcel could not be developed. All wetlands have appropriate buffer areas which will be contained within outlots to be deeded to the city. The developer will place a sign or post indicating conservation area at the rear lot comers of those lots abutting the wetland outlot. 5. Behind lots 4 thru 8, Block 1, between the minimum wetland buffer strip and the rear property lines, we are proposing to keep this area as an enhanced preservation area This would effectively enlarge the buffer area and help filter the rear yard runoff from the wetland. This would enhance and help protect the natural wetland beauty of the site. 6. The developer is currently working with the adjacent land owner to the north in an effort to connect into sanitary sewer service via a manhole located on the landowner's lot. The original plan for this project called for connecting to a manhole approximate 200 feet north of the northeast corner of the property. This original plan would have required the removal of significantly more trees in this area, and would be a large impact to the high quality wetland on the east end of the parcel. We are also in discussions with this land owner to provide them a water service hook up to City water. 7. Installation of a noise wall. As the developer we will be installing an extensive noise wall along Hwy 212 which will not only lessen the highway traffic noise for this property but for the adjacent properties as well. The wall will be constructed to match that of the adjacent existing wall. The wall will be constructed in the MnDOT right-of-way. MnDOT is aware of this proposal and is not opposed to the wall. 8. Clustering the lots allows for reduced hard surface area. While there are no individual lot hard surface requirements, the calculations below demonstrate this claim. Street Pavement Area 44,631 Sq. Ft. Future Trail 3,303 Sq. Ft. Driveway within RIW 4,800 Sq. Ft. (Est. 300 Sq. Ft. per lot) 30% Hard Cover per Lot. 52,272 Sq. Ft. Total Hard Cover 105,006 Sq. Ft. (18.22%) 9. We also are proposing additional trees over and above what is minimally required. Minimally required are 87 trees and 46 shrubs. We are proposing planting 12 (13 % more) trees and 54 additional ornamental grasses. Added to the shrubs, this is a 117% increase. The trees and grasses will enhance the streetscape and provide a visually unifying element. 10. Mail Boxes. A custom designed mail box will be constructed. These will be grouped to minimize street impact and to comply with the US postal service requirements. Placement and design must have final approval by the post office prior to installation. 11. Street Element Plantings. The additional Prairie Fire crabapple trees and Purple Foliage switch grass along with the American Lindens placed approximately every 50 feet along the main entrance and at the trailhead will help to make a unified appearance for the subdivision while helping to make a visual transition from the natural landscape to the urban maintained landscape. The plant materials are native in appearance but by using them often and in a uniform pattern, the image will be one of design and not random as in nature. 12. We are proposing an 8' wide bituminous trail from the cul de sac to the southeast comer of the property. This property is both beautiful with its wetlands and natural areas, and yet has had many constraints that make it difficult to develop. This very beautiful single family development will provide the best situation for land use for this parcel, while still preserving a large portion for open space. This development also creates a buffer between the highway and the adjacent existing neighbors. We ask the City to approve this preliminary plat of The Preserve at Rice Lake so that this subdivision can and will be an amenity to the City of Chanhassen and the surrounding residential neighborhoods for many years to come. Sincerely, John Knoblauch Vice President J & S Ventures Inc. r CITY OF CHANHASSEN CARVER AND HENNEPIN COUNTIES, MINNESOTA FINDINGS OF FACT AND RECOMMENDATION 11►R7A Application of J & S Ventures 1, Inc. and Chestnut Group, LLC for a Land Use Map Amendment from Residential -Low Density to Residential -Low and Medium Density; Rezoning from Single Family Residential (RSF) and Mixed Low Density Residential (R4) to Planned Unit Development -Residential (PUD -R); Subdivision of 13.22 acres into 16 lots and 2 outlots with Variances; Site Plan Review; and Wetland Alteration Permit.

Variance Findings — Section 20-58 of the City Code provides the following criteria for the granting of a variance: The fourth request is to allow reduced setbacks from Highway 212 and length of a cul-de-sac. There will be a noise wall that will separate this development from the highway. The City code requires a minimum setback of 50 feet along the parameter of a planned unit development. The applicant is requesting a 30 -foot setback. a. Variances shall only be permitted when they are in harmony with the general purposes and intent of this Chapter and when the variances are consistent with the comprehensive plan. Finding: The 50 -foot perimeter setback was established to separate potentially incompatible uses. In this area a noise wall will separate the uses. Additional setbacks are not necessary. b. When there are practical difficulties in complying with the zoning ordinance. "Practical difficulties," as used in connection with the granting of a variance, means that the property owner proposes to use the property in a reasonable manner not permitted by this Chapter. Practical difficulties include, but are not limited to, inadequate access to direct sunlight for solar energy systems. 11 40 J Finding: The wetlands on the property and the location of the Highway 212 right-of- way create a practical difficulty in locating houses at the 50 -foot setback. In this area a noise wall will separate the uses. Additional setbacks are not necessary. c. That the purpose of the variation is not based upon economic considerations alone. Finding: The purpose of the variance is not based on economic considerations alone. The applicant is proposing to construct single-family home on residential property at a typical building setback. d. The plight of the landowner is due to circumstances unique to the property not created by the landowner. Finding: The alleged difficulty or hardship is not a self-created hardship. The wetlands on the property and the location of the Highway 212 right-of-way create unique circumstances for the placement of homes. e. The variance, if granted, will not alter the essential character of the locality. (Similar home sizes) Finding: The homes will be compatible with the surrounding area. f. Variances shall be granted for earth sheltered construction as defined in Minnesota Statutes Section 216C.06, subdivision 14, when in harmony with this Chapter. Finding: This does not apply to this request. 9. The city may grant a Variance from the regulations contained in the subdivision ordinance as part of the plat approval process following a finding that all of the following conditions exist: a. The hardship is not a mere inconvenience, but is due to the property being accessed from West 86h Street and then meandering around the wetlands. No additional street access is available to the property due to the wetlands; b. The hardship is caused by the particular physical surroundings, shape or topographical conditions of the land with wetlands located to the north, south and east and west of the site; c. The condition or conditions upon which the request is based are unique and not generally applicable to other property since it is located on property that is hemmed in by wetlands; d. The granting of a variance will not be substantially detrimental to the public welfare and is in accord with the purpose and intent of the subdivision ordinance, the zoning ordinance and the comprehensive plan.

PROPOSAL/SUMMARY The request consists of multiple applications to facilitate the development of a 16 -lot subdivision to house detached homes: Land Use Map Amendment from Residential -Low Density to Residential -Low and Medium Density; Rezoning from Single Family Residential (RSF) and Mixed Low Density Residential (R4) to Planned Unit Development -Residential (PUD -R); Subdivision of 13.22 acres into 16 lots and 2 outlots with Variances; Site Plan Review; and Wetland Alteration Permit. The site is located north of Highway 212 and southeast of the intersection of West 86`" Street and Tigua Lane. Planning Commission Preserve at Rice Lake — Planning Case 2013-12 July 16, 2013 Page 3 of 31 The property is currently zoned RSF — Single Family Residential District and Mixed Low Density Residential District. With the adoption of the 2030 Comprehensive Plan in 2008, the City Council guided the site Residential Low Density. The following is a summary of the requests: 1. Land Use Map Amendment: The first request is to amend the land use plan from Residential -Low Density to Residential -Low and Medium Density. 2. Rezoning: The second request is to rezone the property from Single Family Residential (RSF) and Mixed Low Density Residential (R4) to Planned Unit Development - Residential (PUD -R); and set standards that will govem the development. Since this land is within the shoreland district, the applicant is preserving 50% of the site as open space. 3. Subdivision: The third request is to subdivide 13.22 acres into 16 lots and 2 outlots. There is no minimum lot size in this district. The lot area ranges between 10,000 and 12,723 square feet. The maximum hard surface coverage permitted per lot may not exceed 30%. The applicant submitted a number of typical house designs he intends to build on the proposed lots. Some of the parcels are limited to a single design. A table that lists the maximum hard surface permitted per lot will be incorporated into the standards for this development. 4. Variance: The fourth request is to allow reduced setbacks from Highway 212 and length of a cul-de-sac. There will be a noise wall that will separate this development from the highway. City code requires a minimum setback of 50 feet along the perimeter of a planned unit development. The applicant is requesting a 30 -foot setback. Also, the proposed cul-de-sac is approximately 1,400 feet long, which exceeds the 800 -foot maximum length stipulated in the City Code. Based on the lot configuration and wetland conditions on the site, staff supports the proposed variance. 5. Site Plan Review: The fifth request is to approve a site plan for a medium density development. 6. Wetland Alteration Permit: The sixth request is to allow wetland impacts for the construction of a roadway and trails. Some of these impacts cannot be avoided while others can be avoided. Staff is recommending approval of the proposed development subject to the conditions of the staff report. Planning Commission Preserve at Rice Lake — Planning Case 2013-12 July 16, 2013 Page 4 of 31 EXISTING CONDITIONS The subject site is located north of Highway 212 and southeast of the intersection of West 86i° Street and Tigua Lane. The site has an area of 13.2 acres. It contains multiple wetlands and is within the Rice Marsh Lake Shoreland Overlay District. Access is gained via West 8e Street. The property to the west is zoned PUD and guided Residential Medium Density. It contains the Mission Hills Development, a mix of low and medium density residential development. The property to the north is zoned Single Family Residential and is guided Residential Low Density. It contains single-family homes. The property to the east is zoned High Density Residential District and is guided Parks and Open Space. This land is within the Highway 212 right-of-way. Planning Commission Preserve at Rice Lake — Planning Case 2013-12 July 16, 2013 Page 5 of 31 The project proposes 16 single-family lots. The house pad widths including the garage will range between 50 and 60 feet. The front yard setback will be 25 feet while the side yards will be 10 feet on the house side and 5 feet on the garage side, which is permitted under the PUD ordinance. TYP.

On January 28, 2013, the City Council reviewed the concept plan for The Preserve at Rice Lake - Plannutg Case #2013-02. Planning Commission Preserve at Rice Lake — Planning Case 2013-12 July 16, 2013 Page 6 of 31 On February 11, 2013, City Council approved transmittal for jurisdictional review the land use amendment from Residential — Low Density to Residential — Low and Medium Density. The 60 - day review period ended April 13, 2012. There were no negative comments received. LAND USE MAP AMENDMENT The applicant is requesting a comprehensive plan land use map amendment from Residential — Low Density to Residential — Low and Medium Density. This land use will permit additional flexibility in the design and development of the site and is compatible with the surrounding land uses, which are guided Residential — Medium Density to the west, Residential — Low Density to the north, Parks and Open Space to the east and Highway 212 to the south. Existing Land Use APPLICABLE REGULATIONS Proposed Land Use The city is acting within its legislative capacity in making amendments to the comprehensive plan. As part of the process, the city will be making a policy decision. Approval of the development is contingent upon approval of land use amendment. ANALYSIS Part of the difficulty in developing this site are the wetlands that are located on the property, as well as its location within the Rice Marsh Lake Shoreland Overlay District. The site is accessible via 8e Street/Tigua lane and would follow an old farm access road through the wetland complex. This type of land use, a mix of Residential Low and Medium Density, permits Planned Unit Developments with clustered homes and no minimum lot size. This will allow staff to work with the applicant to maximize preservation and enhancement of natural features. It also allows the city to determine the best type of housing development (attached versus detached housing). Planning Commission Preserve at Rice Lake — Planning Case 2013-12 July 16, 2013 Page 7 of 31 Existing Conditions The goal is to allow the development with minimum impact to the natural features of the site. Staff found that in this situation the application of standard Single Family Residential regulations would be impractical due to 1) the desire to build single-family detached homes on the site, 2) the presence of the 15,000 square -foot minimum lot size for non -riparian lots and 90 -foot frontage, and 3) wetlands. Staff finds that a preferred alternative to achieve this goal would be to guide the site Residential Medium Density. This category allows the clustering of homes with no minimum lot size or frontage. In this case, the homes will be placed in locations that will have the least impact on the natural features and will allow the applicant the opportunity to enhance the wetlands and surrounding buffer. At the same time, the developer would be able to build the single-family detached homes. The following elements of the comprehensive plan discuss land use policies that should be evaluated in changing the land use. Chanter 2 Land Use Element 2.5.2 Residential — low density The dominate type of development within the residential district is low-density, single-family detached housing. Net densities within this category range from 1.2 to 4.0 units per acre. For projection of land demand, an average density of two dwelling units per acre was used. There are several zoning applications within the low density including RSF (Residential Single Family), R- 4 (Mixed Low Density), RLM (Residential Low and Medium Density), and PUD -R (Planned Unit Development -Residential). Planning Commission Preserve at Rice Lake — Planning Case 2013-12 July 16, 2013 Page 8 of 31 2.5.3 Residential — Medium density The medium density designation is intended to accommodate multiple units including duplexes, townhouses and lower -density apartments or condominiums. A net density range of 4.0 — 8.0 units per acre is covered by this category with an expected density of 6.0 units per acre. The zoning options in the medium density land use include R4 (Mixed Low Density), RLM (Residential Low and Medium density), R-8 (Mixed Medium Density Residential) and PUD -R (Planned United Development -Residential). Medium density is viewed as transitional use between low density and Commercial, office or high-density areas. Comprehensive Plan Goals and Policies 4.6 Housing Goals and Policies Goals: Provide housing opportunities for all residents, consistent with the identified community goals: • A variety of housing types for all people in all stages of the life cycle. • A community of well-maintained housing and neighborhoods, including ownership and rental housing. • Housing development that respects the natural environment of the community while striving to accommodate the need for a variety of housing types and costs. • The availability of a full range of services and facilities for its residents, and the improvement of access to a linkage between housing and employment. • Housing development methods such as PUDs, cluster development, and innovative site plans and building types, should be encouraged to help conserve energy and resources for housing. Justification for Rezoning to PUD The applicant is requesting to rezone 13.23 acres from Single Family Residential (RSF) and Mixed Low Density Residential (R4) to Planned Unit Development -Residential (PUD -R). The project consists of 16 single-family homes. The review criteria are taken from the intent section of the PUD Ordinance. For a property guided Medium Density Residential, zoning consistent with the land use includes RLM, Residential Low and Medium Density District, R-8, Mixed Medium Density Residential District or PUD -R, Planned Unit Development — Residential. Since the developer wanted a development of single-family detached housing, the R-8 district did not work because it does not permit single-family detached homes. Initially, the developer tried to use the RLM district as well as the RSF district; however, due to site topography, shoreland overlay district and the location of wetlands, the developer could not meet the minimum standards for the lots and many lot width and area variances would have been required. Since the PUD -R district creates its own Planning Commission Preserve at Rice Lake — Planning Case 2013-12 July 16, 2013 Page 9 of 31 standards, we were able to accommodate the development while preserving significant environmental features. If the property was reguided to medium density residential, the developer must maintain a minimum density of 4.0 units per acre. As proposed, the net density of the project is 4.0 units per acre. Section 20-501. Intent Planned unit developments offer enhanced flexibility to develop a site through the relaxation of most normal zoning district standards. The use of the PUD in this instance is to allow for lot dimension flexibility. In exchange for this enhanced flexibility, the City has the expectation that the development plan will result in a significantly higher quality and more -sensitive proposal than would have been the case with the other more standard zoning districts. The proposed development provides a compatible development with the surrounding development and is consistent with the comprehensive plan subject to the conditions of approval. The proposed rezoning assists in the furtherance of the following land use goals of the City of Chanhassen Comprehensive Plan: • Development will be encouraged within the MUSA line. • The plan should seek to establish sufficient land to provide a full range of housing opportunities. • The city will seek opportunities to provide transitions between different uses of different types. • Development should be phased in accordance with the ability of the city to provide services. The proposed rezoning assist in the furtherance of the following housing goals of the City of Chanhassen Comprehensive Plan: • A balanced housing supply with housing available for people of all income levels. • A variety of housing types for people in all stages of the life -cycle. Housing development that respects the natural environment of the community while striving to accommodate the need for a variety of housing types and costs. Planning Commission Preserve at Rice Lake — Planning Case 2013-12 July 16, 2013 Page 10 of 31 Staff is proposing the following development standards govern the development of the property. DEVELOPMENT DESIGN STANDARDS PRESERVE AT RICE LAKE a. Intent The purpose of this zone is to create a PUD for a single-family detached development. The use of the PUD zone is to allow for more flexible design standards while creating a higher quality and more -sensitive proposal. The PUD requires that the development demonstrate a higher quality of architectural standards and site design. Except as modified by the Preserve at Rice Lake development standards, the development must comply with the Residential Low and Medium Density District, RLM. b. Permitted Uses The permitted uses in this zone shall be limited to single-family detached houses and their ancillary uses. The type of uses to be provided on common areas shall be low -intensity neighborhood - oriented accessory structures to meet daily needs of residents. Such uses may include development signage, garden, gazebo, maintenance shed, picnic shelter, permanent open space, playground equipment and trails. C. Setbacks The PUD ordinance requires setbacks from roadways and property lines. The following table displays those setbacks. *Lot coverage may not exceed those established in the compliance table.

There are added amenities to the surrounding neighbors. e) The proposed use can be accommodated with existing public services and will not overburden the city's service capacity. Finding: The site is located within the Municipal Urban Service Area. The proposed use can be accommodated with existing public services and will not overburden the city's service capacity. f) Traffic generation by the proposed use is within capabilities of streets serving the property. Finding: Traffic generation by the proposed use is within capabilities of streets serving the property. Planning Commission Preserve at Rice Lake — Planning Case 2013-12 July 16, 2013 Page 13 of 31 SUBDIVISION REVIEW The developer is proposing to subdivide 13.23 acres into 16 lots and two outlots. The outlots contain wetlands, storm ponds and open space. The applicant intends to dedicate the outlots to the city. Staff believes that these outlots should be preserved as permanent open space. There are no minimum lot area or minimum lot dimensions under the medium density planned unit development district. The hard surface coverage of the individual lots may not exceed 301/0. Staff prepared a table that includes the maximum square footage of hard surface on each individual lot. Subdivision Findings 1. The proposed subdivision is consistent with the zoning ordinance; Finding: The subdivision meets all the requirements of the Planned Unit Development and the zoning ordinance subject to conditions. 2. The proposed subdivision is consistent with all applicable city, county and regional plans including but not limited to the city's comprehensive plan; Finding: The proposed subdivision is consistent with the comprehensive plan and subdivision ordinance contingent upon approval of the comprehensive plan amendment and conditions. 3. The physical characteristics of the site, including but not limited to topography, soils, vegetation, susceptibility to erosion and siltation, susceptibility to flooding, and storm water drainage are suitable for the proposed development; Finding: The proposed site is suitable for development subject to the conditions specified in this report. Planning Commission Preserve at Rice Lake — Planning Case 2013-12 July 16, 2013 Page 14 of 31 4. The proposed subdivision makes adequate provision for water supply, storm drainage, sewage disposal, streets, erosion control and all other improvements required by this chapter; Finding: The proposed subdivision is served by adequate urban infrastructure. 5. The proposed subdivision will not cause environmental damage; Finding: The proposed subdivision will not cause significant environmental damage subject to conditions of approval. The proposed subdivision contains adequate open areas. 6. The proposed subdivision will not conflict with easements of record. Finding: The proposed subdivision will not conflict with existing easements, but rather will expand and provide all necessary easements. 7. The proposed subdivision is not premature. A subdivision is premature if any of the following exists: a. Lack of adequate storm water drainage. b. Lack of adequate roads. C. Lack of adequate sanitary sewer systems. d. Lack of adequate off-site public improvements or support systems. Finding: The proposed subdivision will have access to public utilities and streets. VARIANCE The applicant is requesting a reduced setback from Highway 212. City Code requires all buildings to maintain a 50 -foot setback from arterial or collector streets. The reason behind the variance request is the fact that there will be a noise wall that will separate the subject site from the highway. The applicant is requesting structures maintain a 30 -foot setback from the north property line. The applicant is also requesting a variance for the length of the cul-de-sac serving the subject site. City Code limits the length of a cul-de-sac to 800 feet. The proposed cul-de-sac is approximately 1,400 feet long, which exceeds the 800 -foot maximum length stipulated in the City Code. Based on the lot configuration and wetland conditions on the site, staff supports the proposed variance. The setback variance is addressed under City Code Chapter 20 -Zoning, Sec. 20-58. The variance for the length of the cul-de-sac is addressed under City Code Chapter 18 -Subdivisions, Sec. 18-22. Variance Findines — Setback. Chapter 20 Section 20-58 of the City Code provides the following criteria for the granting of a variance: Planning Commission Preserve at Rice Lake — Planning Case 2013-12 July 16, 2013 Page 15 of 31 a. Variances shall only be permitted when they are in harmony with the general purposes and intent of this Chapter and when the variances are consistent with the comprehensive plan. Finding: The 50 foot perimeter setback was established to separate potentially incompatible uses. In this area a noise wall will separate the uses. Additional setbacks are not necessary. b. When there are practical difficulties in complying with the zoning ordinance. 'Practical difficulties," as used in connection with the granting of a variance, means that the property owner proposes to use the property in a reasonable manner not permitted by this Chapter. Practical difficulties include, but are not limited to, inadequate access to direct sunlight for solar energy systems. Finding: The wetlands on the property and the location of the Highway 212 right-of- way create a practical difficulty in locating houses at the 50 foot setback. In this area a noise wall will separate the uses. Additional setbacks are not necessary. c. That the purpose of the variation is not based upon economic considerations alone. Finding: The purpose of the variance is not based on economic considerations alone. The applicant is proposing to construct single-family home on residential property at a typical building setback. d. The plight of the landowner is due to circumstances unique to the property not created by the landowner. Finding: The alleged difficulty or hardship is not a self-created hardship. The wetlands on the property and the location of the Highway 212 right-of-way create unique circumstances for the placement of homes. e. The variance, if granted, will not alter the essential character of the locality. (Similar home sizes) Finding: The home will be located in the interior of the proposed development and will be compatible with the other homes. f. Variances shall be granted for earth sheltered construction as defined in Minnesota Statutes Section 216C.06, subdivision 14, when in harmony with this Chapter. Finding: This does not apply to this request. Variance Findings — Length of cul-de-sac. Chapter 18 Section 18-22 of the City Code provides the following criteria for granting a variance: Planning Commission Preserve at Rice Lake — Planning Case 2013-12 July 16, 2013 Page 16 of 31 The city council may grant a Variance from the regulations contained in this chapter as part of the plat approval process following a finding that all of the following conditions exist: a. The hardship is not a mere inconvenience; Finding: The hardship is not a mere inconvenience, but is due to the property being accessed from West 86d' Street and then meandering around the wetlands. No additional street access is available to the property due to the wetlands. b. The hardship is caused by the particular physical surroundings, shape or topographical conditions of the land; Finding: The hardship is caused by the particular physical surroundings, shape or topographical conditions of the land with wetlands located to the north, south and east and west of the site. c. The condition or conditions upon which the request is based are unique and not generally applicable to other property; Finding: The condition or conditions upon which the request is based are unique and not generally applicable to other property since it is located on property that is hemmed in by wetlands. d. The granting of a variance will not be substantially detrimental to the public welfare and is in accord with the purpose and intent of this chapter, the zoning ordinance and comprehensive plan. Finding: The granting of a variance will not be substantially detrimental to the public welfare and is in accord with the purpose and intent of the subdivision ordinance, the zoning ordinance and the comprehensive plan. SHORELAND REGULATIONS The site is located within the Rice Marsh Lake Shoreland Overlay District (area located within 1000 feet from the High Water Level of a lake) and is subject to the standards and requirements of the Department of Natural Resources (DNR) and City Code. The intent of the shoreland rules are to protect the habitat, viewscape and water quality of the waters of the state by setting design standards to this end. Planning Commission Preserve at Rice Lake — Planning Case 2013-12 July 16, 2013 Page 17 of 31 This property lies within the Shoreland Management District and is subject to the Planned Unit Development (PUD) requirements. The applicant must demonstrate that by granting the flexibility that comes with a PUD, enhancements are made that would not be seen with a straight single-family residential development plan. Given that wetlands are protected under Chanhassen City Code, the Minnesota Wetland Conservation Act, and in many instances the Federal Clean Water Act, the act of preserving wetlands is not a benefit that would not otherwise be realized. Further, the proposed buffer areas are the minimum required and would be the same with a straight subdivision. There is no enhancement being proposed. All stormwater management is contained within the outlot areas. This is standard practice. However, these outlot areas are considered to be the 50% open space as required by the Shoreland PUD rules. The creation of these ponds results in significant disturbance in the areas to be preserved as naturalized open space. A detailed management plan shall be included to manage these disturbed areas to meet with the intent of the open space preservation. Unlike single-family lots that fall within the shoreland district and are guided low density, there are no minimum lot widths or areas for medium density lots within a shoreland district. Other design standards apply to these lots as follows: The development must comply with the MN Rules Chapter 6120 and the DNR must issue their concurrence to this effect. An adequate stormwater management and erosion sediment control plan must be provided. These will be addressed under a separate heading. DNR regulations (section 6120.3800, subp. 5. B. (2) (a)) require that "at least 50 percent of the total project area within the shoreland district, which extends 1,000 feet out from the edge of the lake, must be preserved as open space". The total area of the site is 13.23 acres. The applicant is proposing to maintain 57% of the site as open space which exceeds the DNR requirements.

Planning Commission Preserve at Rice Lake — Planning Case 2013-12 July 16, 2013 Page 18 of 31 WETLAND PROTECTION Graham Environmental Services, Inc. (GES) performed an on-site wetland determination and boundary delineation on April 28 and May 4, 2011. This was reviewed by city staff as the local government unit (LGU) responsible for administration of the Wetland Conservation Act and submitted to the technical evaluation panel for comment. Based upon review of the delineation, the boundaries were approved excepting that Wetland C and Wetland D were determined to be part of the same basin and Wetland B was expanded to the north. The current plan submittal appears to accurately reflect these modified boundaries. The plan set was provided by Probe Engineering Company, Inc. on behalf of J&S Ventures. While it does show all wetlands and their accurate boundaries, it does not provide unique nomenclature. As such, references to specific wetland basins refer back to the approved delineation and are summarized in the following figure. The plan shows the required buffer around wetlands A through D but fails to show a buffer around wetland E. All wetlands require the establishment of buffer areas and setbacks per Section 20-411 of Chanhassen City Code. Any wetland buffer areas that are disturbed do not meet the requirement for native vegetation as stated in §20-411, or which contains noxious weeds must have a detailed vegetation management plan and that plan must be followed. The submitted plan defines the extent of three impact areas. A fourth impact is inevitable based upon the proposed future trail alignment. Two impacts (both to Wetland A) are a result of the access road into the site. The proposed impacts to Wetland C are a result of the chosen trail alignment and can be avoided through a reconfiguration of the trail alignment or by moving the cul-de-sac farther north. Section 20-401(b) reads that "The intent of this article is to avoid alteration and destruction of wetlands. When this is not feasible, mitigation must be provided to recreate the function and value of the lost or altered wetlands." Planning Commission Preserve at Rice Lake — Planning Case 2013-12 July 16, 2013 Page 19 of 31 Section 20-410(b)(4) reads that "The size of the altered area shall be limited to the minimum required for the proposed action." Minnesota Rules 8420 (the Minnesota Wetland Conservation Act) regulates the protection of wetlands within the state of Minnesota. Section 8420.520 SEQUENCING stipulates that an LGU "must not approve a wetland replacement plan unless the local government finds that the applicant has demonstrated that they have met the sequencing requirements of the Wetland Conservation Act." The first goal must always be to avoid a wetland impact. Minnesota Rules 8420.520 Subp. 3 C. reads as follows: (2) The local government unit must determine whether any proposed feasible and prudent alternatives are available that would avoid impacts to wetlands. An alternative is considered feasible and prudent if it meets all of the following requirements: (a) it is capable of being done from an engineering point of view; (b) it is in accordance with accepted engineering standards and practices; (c) it is consistent with reasonable requirements of the public health, safety, and welfare; (d) it is an environmentally preferable alternative based on a review of social, economic, and environmental impacts; and (e) it would create no truly unusual problems. Minnesota Rules 8420.0520 Subp. 3 C. goes on to say: (4) If the local government unit determines that a feasible and prudent alternative exists that would avoid impact to wetlands, it must deny the replacement plan. The applicant was made aware of this law on several occasions including meetings on January 2, 2013 and February 13, 2013, as well as in the staff report reviewing the concept plan dated January 15, 2013. Specifically, the location of the sidewalk and the subsequent trail extension was discussed. It was pointed out that by moving the sidewalk to the north side of the proposed road and having it connect with the regional trail between lots 11 and 12, both wetland impacts could be avoided to wetland C/D and would be feasible and prudent under the previous five criteria. Wetland impact avoidance is not the sole reason for realignment of the trail. This configuration would also provide for more cost-effective and efficient maintenance of the access to the regional trail; it would give direct access to the residents the sidewalk is meant to serve; the regional trail would not be subject surface flow over the trail creating potential safety risks; the city would save on the expense of installing a boardwalk over the wetland; and would allow for snow storage in an area that would otherwise be a trail adjacent to the wetland in question. The Minnesota Local/State/Federal Application for Water/Wetland Projects was submitted. This application did not include a sequencing discussion for the two impacts related to the trail as required by the Minnesota Wetland Conservation Act. The Application for Withdrawal of Planning Commission Preserve at Rice Lake — Planning Case 2013-12 July 16, 2013 Page 20 of 31 Wetland Credits Form as required in item 14 on page 5 was not included with the Wetland Application and has yet to be provided to the City. Item 11 on Page 4 requires that the proposed wetland impacts are listed individually. This was not done. For these reasons, this application is incomplete and fails to meet the sequencing argument necessary to justify the impact and subsequent replacement plan. The applicant must either move the trail to the north or show conclusively why that configuration would not meet the five (5) criteria listed in Minnesota Rules 8420.520 Subp. 3 C. (2). The applicant must supply a completed Application for Withdrawal of Wetland Credits Form. The applicant must show all proposed impacts related to this project on all pertinent plan sets and itemize them within the application. Wet/and Aheradon Permit Findings: a. The proposed development will not be detrimental to or degrade the public health, safety, comfort, convenience or general welfare of the neighborhood or the city. b. The proposed development will be consistent with the objectives of the city's comprehensive plan and this chapter. c. The proposed development will be designed, constructed, operated and maintained so to be compatible in appearance with the existing or intended character of the general vicinity and will not change the essential character of that area. d. The proposed development will not be hazardous or disturbing to existing or planned neighboring uses. e. The proposed development will be served adequately by essential public facilities and services, including streets, police and fire protection, drainage structures, refuse disposal, water and sewer systems and schools; or will be served adequately by such facilities and services provided by the persons or agencies responsible for the establishment of the proposed use. f. The proposed development will not create excessive requirements for public facilities and services and will not be detrimental to the economic welfare of the community. g. The proposed development will not involve uses, activities, processes, materials, equipment and conditions of operation that will be detrimental to any persons, property or the general welfare because of excessive production of traffic, noise, smoke, fumes, glare, odors, rodents, or trash. h. The proposed development will have vehicular approaches to the property which do not create traffic congestion or interfere with traffic or surrounding public thoroughfares. i. The proposed development will not result in the destruction, loss or damage of solar access, natural, scenic or historic features of major significance. j. The proposed development will be aesthetically compatible with the area. Planning Commission Preserve at Rice Lake — Planning Case 2013-12 July 16, 2013 Page 21 of 31 k. The proposed development will not depreciate surrounding property values. 1. The proposed development will meet standards prescribed for certain uses as provided in the Conditional Use article. Finding: As discussed above, the proposed impacts to Wetland C are a result of the chosen trail alignment and can be avoided through a reconfiguration of the trail alignment or by moving the cul-de-sac farther north. The applicant fails to meet the sequencing argument necessary to justify the impact and subsequent replacement plan. ROADWAYS The property lies north of Highway 212, east of County Road 101 and south of West 86th Street. The proposed access on West 86th Street is located so as to minimize wetland impacts. To further reduce wetland impacts, staff supports a reduced right-of-way width (50 feet, with a 15 - foot front yard drainage and utility easement) and a reduced street width (28 feet) for the portion of the road that does not have any lots adjacent to it (approximately 400 feet). The remainder of the street and right-of-way shall meet the City's minimum requirements. The proposed street curves do not meet a 30 mph design speed; advanced warning and speed advisory signs would be required. The proposed cul-de-sac is approximately 1,400 feet long, which exceeds the 800 -foot maximum length stipulated in the City Code. Based on the lot configuration and wetland conditions on the site, staff supports the proposed variance. RETAINING WALLS A retaining wall is proposed on the west side of the road, in the southwest comer of the site. The maximum height of the wall as shown on the grading plan is five feet; therefore, a building permit is required to construct the wall. Plans must be submitted with the permit application and must be signed by an engineer registered in the State of Minnesota. UTILITIES A 12 -inch trunk watermain extends from the townhome development to the west to the Reflections development south of Highway 212. The developer proposes to extend lateral watermain from this trunk line to service the development. Based on the proposed elevations of the homes, the operating water pressures within the homes will meet the minimum required per 10 States Standards; however, some homes may choose to install a privately -owned and maintained booster to provide a higher water pressure. The watermain shall be 8 -inch PVC (C-900). The developer proposes to extend lateral sanitary sewer from the existing 8 -inch lateral sanitary sewer north of the site. The developer is required to get the necessary easement to complete this work prior to final plat submittal. Planning Commission Preserve at Rice Lake — Planning Case 2013-12 July 16, 2013 Page 22 of 31 Street and utility plan and profile construction plans must be submitted with the final plat. A portion of the trunk sewer and water hookup fees must be paid in cash with the final plat in the rate in effect at that time. The property was assessed $8,700 for the 2006 Trunk Watermain Extension. This assessment was certified to Carver County property taxes; therefore, the final payment will be made with the second half taxes or when the property is final platted, whichever event takes place first.

This fee is broken into water quality and water quantity and is based upon net developable acreage and a multiplier intended to reflect the anticipated burden the land use will place upon the storm sewer system relative to other land uses. Credit is then given for storm water management best management practices at a rate of 50% the water quality rate per acre treated. The estimated total Storm Water Management Connection fee is 67,483.50. The following table shows the calculations. EROSION PREVENTION AND SEDIMENT CONTROL Peak discharge rates are increased at both places where drainage will leave the site. In both instances the outlet channel has become incised and headcuts are forming within the channel. At the outfall downstream of the driveway, a surge basin was installed at some point in the past. The channel has since worked around either side of the surge basin as illustrated in the photograph to the left. The other channel is incised. The depth of this incision will increase and will almost certainly Planning Commission Preserve at Rice Lake — Planning Case 2013-12 July 16, 2013 Page 23 of 31 accelerate as the discharge rate and, therefore, the scour force within the channel increases. In both instances, this channel discharges to Rice Marsh Lake and the resulting erosion will lead to increased sediment deposition into the lake. Efforts must be taken to reduce the rate of runoff or assure that the channels are stabilized to prevent further degradation. The total disturbed area is unknown but is certainly greater than one acre in size. Given the total disturbance it must be compliant with the National Pollution Discharge Elimination System General Permit Authorization to Discharge Stormwater Associated with Construction Activity (NPDES Construction Permit). As part of this permit, the applicant is required to develop a Surface Water Pollution Prevention Plan (SWPPP) with three elements: a narrative, plan sheets and standard detail plates. Each of these elements requires specific content. Section 19-145 of Chanhassen City Code requires that the construction is compliant with the NPDES Construction Permit and the SWPPP is provided to the City for review and comment. The current submittal is lacking the majority of the required SWPPP content. The Minnesota Pollution Control Agency has developed a checklist to determine if the required content is included. Rather than enumerate the deficiencies, the applicant and their consultant are referred to this document and Part III of the NPDES Construction Permit. Additionally, the new NPDES Construction Permit was approved on June 25, 2013 and will go into effect on August 1, 2013. It will be incumbent upon the applicant to determine if compliance with the new permit will be necessary or if this project will be permitted under the permit that expires on July 31, 2013. Staff will make available to the consulting engineer a redlined set of the current plans and an example of a SWPPP that was authored by the city. COMPREHENSIVE PARK PLAN The city's comprehensive park plan calls for a neighborhood park to be located within one-half mile of every residence in the city. The proposed Preserve at Rice Lake development would not meet this guideline. The nearest park is Rice Marsh Lake Park which is located approximately one mile away if utilizing the city's pedestrian trail network. COMPREHENSIVE TRAIL PLAN The city's comprehensive trail plan calls for the future completion of a Rice Marsh Lake Trail to be constructed around the perimeter of the lake. This proposed subdivision should provide for and construct a trail connection to this future trail starting at the public street and extending to the southeast corner of the property. This trail connection should be situated in a public outlot or trail easement. The developer shall pay full park fees in effect at the time of final plat approval. LANDSCAPING AND TREE PRESERVATION The applicant has provided a tree inventory and removal plan for the subdivision. Bufferyard plantings are required for this development along Highway 212. Tree preservation calculations for the development are shown below. Planning Commission Preserve at Rice Lake — Planning Case 2013-12 July 16, 2013 Page 24 of 31 Total upland area (excluding wetlands) Total canopy area (excluding wetlands) Baseline canopy coverage Minimum canopy coverage allowed Proposed tree preservation 413,111 SF or 9.48 ac. 66,600 SF or 1.52 ac 16% 25% or 103,277 SF 4% or 16,820 SF The developer does not meet minimum canopy coverage allowed. Additional plantings will be required to bring the baseline canopy coverage up to the minimum required. Required plantings 87 trees (66600-16820)x1.2 54 trees required (103277-66600) 33 trees required The applicant has proposed a total of 48 new trees and 50 transplanted evergreens in the landscape plan. The applicant is required to provide bufferyards along Highway 212. The minimum plantings required and the applicant's proposed quantities are shown in the table below. The applicant does not meet minimum requirements for bufferyard plantings along the south property line. All but a handful of trees are located offsite on MnDOT property. Staff recommends the landscaping be located on the applicant's property unless proof of MnDOT approval is given to the city. NOISE STUDY The developer has prepared a noise analysis for noise that will be generated by traffic on Highway 212. The analysis identified appropriate noise mitigation measures to meet noise standards for residential homes as specified by the Minnesota Pollution Control Agency. The wall is proposed to be in the MnDOT right-of-way, which shall be implemented by the developer. The following is a summary of the traffic noise assessment which was conducted by David Braslau Associates, Inc.: • Traffic noise levels have been predicted for the Preserve at Rice Lake location north of TH 212 in Chanhassen, Minnesota. • The analysis has been performed for 16 receptor locations both at the ground floor and upper or second -story level. • A noise wall on top of the existing berms that will extend the existing noise wall to the west is proposed. Required Proposed South property line - 15 overstory trees 7 overstory trees Hwy 212, bufferyard B, 31 understory trees 4 understory trees 956' 46 shrubs 50 transplant evergreens 36 shrubs The applicant does not meet minimum requirements for bufferyard plantings along the south property line. All but a handful of trees are located offsite on MnDOT property. Staff recommends the landscaping be located on the applicant's property unless proof of MnDOT approval is given to the city.

Planning Commission Preserve at Rice Lake — Planning Case 2013-12 July 16, 2013 Page 25 of 31 • The top of the wall elevation is 924 and the wall varies in height from 8 feet on the west to 10 feet on the east, with a higher wall between the berms and on the east end, where a short wrap-around wall is proposed. • With the wall, all of the ground level receptors are predicted to be below the daytime L10 65 dBA standard for residential land uses. All second -story receptors are also predicted to be below the standard except the two closest, which are estimated to be only 2 dBA over the daytime standard. • Nighttime (6-7 am) levels at all of the receptor sites are estimated to be over the L10 55 dBA standard. • However, exceptions to the noise standards permit the NAC -2 or Commercial Noise Standard to be applied which is L10 70 dBA, providing certain conditions are met. With appropriate home construction, these conditions should be met so that all receptor sites will be in compliance with the state noise standards. RECOMMENDATION A. COMPREHENSIVE PLAN AMENDMENT Staff recommends that the Planning Commission approve the land use map amendment from Residential — Low Density to Residential — Low and Medium Density with the following condition, and adoption of the attached Findings of Fact and Recommendation: Approval of the Land Use Amendment is subject to Metropolitan Council determination of consistency with system plan. B. REZONING Staff recommends that the Planning Commission approve the rezoning from Residential — Low Density (R4) and Mixed Low Density Residential (R8) to Planned Unit Development — Residential (PUD -R) with the following condition; and adoption of the attached Findings of Fact and Recommendation and attached ordinance rezoning the property. Approval of the Rezoning is contingent upon approval of the final plat and execution of the development contract. C. PRELIMINARY PLAT: Staff recommends that the Planning Commission approve the preliminary plat to subdivide 13.22 acres into 16 lots and 2 outlots as shown in plans dated received June 14, 2013 with the following conditions, and adoption of the attached Findings of Fact and Recommendation: L All lots must comply with the following table: Planning Commission Preserve at Rice Lake - Planning Case 2013-12 July 16, 2013 Page 26 of 31 COMPLIANCE TABLE Wetland setback: 20 ft. buffer, 30 ft. principal structure, 15 ft. accessory structure.

The applicant shall increase bufferyard plantings along the south property line to meet minimum requirements. 5. Advanced warning and speed advisory signs are required where the design speed is less than 30 mph. 6. The site plan and HydroCAD model must be revised to address the following comments: a. Peak discharge rates are proposed to increase at the following locations: i. Runoff leaving the overall site for the two-year (2.8 -inch) rainfall and snowmelt events. ii. Runoff leaving the wetland located on the western portion of the site for each design event. iii. Runoff leaving the site to the north for the snowmelt event. b. Use a pond in the model at the 18 -inch culvert located north of the site. c. The analysis should reflect any overtopping of the driveway or other overland flows that may occur. d. Due to the increased velocities through the 12 -inch culvert leaving the western wetland, the developer must provide a design to address associated erosion at this location. Any required improvements outside of existing easements shall require additional easements. e. The drainage areas and/or curve number in the HydroCAD model must correspond to the Drainage Area and Curve Number Table. f. Directly connected impervious areas must be modeled separately rather than included in the composite Curve Number computation. g. The applicant must provide calculations (or submit a model) demonstrating that the city's requirements for water quality are satisfied. i. If the event -based NURP standard cannot be achieved by dead pool storage, then (P8 or other) calculations should be based on equivalent annual removal efficiencies. ii. If an iron -enhanced filtration system is included in the design, calculations should be provided demonstrating the water quality treatment benefits of the BMP. Detailed plans of the system should be submitted for review with the calculations. iii. The report notes that the east pond is able to remove 87.8% of the phosphorus load. This removal efficiency appears excessively high. It is anticipated that there is either an error with the model inputs or the calculation was performed for a particular rainfall event rather than annualized removal efficiency. Planning Commission Preserve at Rice Lake — Planning Case 2013-12 July 16, 2013 Page 28 of 31 7. The HydroCAD model must be revised so that the impervious surface of the lots is 301/6. 8. If groundwater is encountered during site construction the lowest floor elevations must be adjusted so that there is a minimum three-foot separation. 9. The developer must provide additional information showing how the proposed "Preservation/Stormwater Volume Reduction Area" between the large wetland and the back of Lots 4-7, Block 1 will meet the minimum requirements. 10. Storm sewer sizing calculations must be submitted with the final plat application and shall include the existing storm sewer at Tigua Lane (approximately 280 feet east of the proposed street intersection). The existing 12 -inch reinforced concrete pipe north of Lots 7 and 8, Block 1 shall also be included in the analysis. 11. The grading plan must be revised to address the following comments: a. The developer must obtain a MnDOT permit for the proposed grading within the MnDOT right-of-way. b. The grading plan must be revised at the slope down from the street to the wetland at Station 3+00, and between Lots 3 and 4, Block 1 so the slope does not exceed 311: IV. c. The lowest openings of Lots 2 and 3, Block 2 must be at least one foot above the emergency overflow elevation. d. The minimum floor elevation of Lots 8, 9 and 10, Block 1 shall be 897.6'. e. The building envelope for Lot 3, Block 2 must not encroach into the drainage and utility easement. f. The sideyard drainage and utility easements between Lots 10 and 11, Block 1 must match what is shown on the plat. g. The building pad shown for Lot 1, Block 2 cannot accommodate any of the house styles provided and must be revised accordingly. h. It is difficult to discern between the proposed contours, lot lines and setback lines. The developer's engineer is requested to change the drawing line weights. 12. A building permit is required to construct the proposed retaining wall. Plans must be submitted with the permit application and must be signed by an engineer registered in the State of Minnesota. 13.

This should include, among the other listed requirements, all temporary and permanent best management practices. 21. There is significant evidence of gully erosion at both off-site discharge locations. Rates must be reduced below existing discharge rates or efforts must be taken to stabilize these discharge points to prevent further channel incision and head cutting. 22. A vegetation establishment and management plan must be developed for all areas preserved as open space including those areas graded for the construction of stormwater management practices that are above the normal water level. 23. Minnesota Department of Transportation right-of-way is outside of the City of Chanhassen's WCA jurisdiction as MnDOT is their own LGU. Chanhassen's review of wetland boundaries ended at the property limits. The applicant must get all appropriate approvals from MnDOT for work on the sound wall. 24. The development must comply with the MN Rules Chapter 6120 and the DNR must issue their concurrence to this effect. 25.

PUBLIC HEARING: PRESERVE AT RICE LAKE: REOUEST FOR LAND USE MAP AMENDMENT FROM RESIDENTIAI,LOW DENSITY TO RESIDENTIAL LOW AND MEDIUM DENSITY: REZONING FROM SINGLE FAMILY RESIDENTIAL (RSF) AND MIXED LOW DENSITY RESIDENTIAL (R4) TO PLANNED UNIT DEVELOPMENT -RESIDENTIAL (PUD -R): SUBDIVISION OF 13.22 ACRES INTO 16 LOTS AND 2 OUTLOTS WITH VARIANCES: SITE PLAN REVIEW: AND WETLAND ALTERATION PERMIT. APPLICANT: J & S VENTURES 1, INC.. PLANNING CASE 2013-12. Al-Jaf. . The subject site is located south, at the southeast intersection of Tigua Lane and West 86h Street, north of Highway 212. Staff would like to briefly go over the existing conditions of this specific site. It 22 SCANNED Chanhassen Planning Commission — July 16, 2013 is located north of Highway 212. The site has an area of 13.2 acres and it contains multiple bodies of wetlands. Access to the site is gained via 86d' Street. Another existing condition with the site is the fact that it falls within the shoreland overlay district of Rice Marsh Lake. This is Rice Marsh Lake. The entire area that is within 1,000 feet of this, of the ordinary high water mark of the lake is considered shoreland. And as you can see the portion of the site that is highlighted, shaded in this light blue in it's entirety falls within the shoreland overlay district. Every single parcel proposed on this site is within this overlay district with the exception of Lot number I but even then it, the overlay district touches it. The existing land use for this development is low density residential. That type of development would allow for single family homes as well as attached townhomes. Attached single family homes as long as the density does not exceed 4 units per acre. The current site has two zonings. The portion of the site to the west is currently zoned RSF while the eastern half is zoned R-4 which allows up to 4 units per acre. And briefly the property to the north of the site is zoned RSF, Residential Single Family. Property to the west contains townhomes and has an 8 unit per acre density. Property to the east is actually open space and to the south is the Highway 212. So the proposal before you will, has multiple components. The first one is a land use map amendment. There's a rezoning, a subdivision, a couple of variances, a site plan review as well as a wetland alteration permit and staff will briefly go through these different items. One of the first things that we looked at was, what was it that the developer was trying to achieve. The reason I went through, staff went through the background and features of the site is just to give you an idea of the environmental sensitivity of the site. With all of these items that we detailed, development becomes constrained. There are certain setbacks that the different ordinances, different agencies that have jurisdiction over this site would, that the applicant would need to meet. One of the main constraints was the fact that the applicant wanted to develop this site as a single family development and it would be a total of 16 lots. The lots were, that the applicant is proposing, typical parcel would have a 25 foot front yard setback, 30 foot rear yard and then as far as setbacks, the garage would have a 5 foot setback. The other side, living space would have a 10 foot separation between homes. Any two homes would have to maintain 15 feet so that's what they are trying to achieve. If we look under the, I mentioned this is in the shoreland overlay district. If we look at the shoreland overlay district requirements, they require that each parcel maintains a 90 foot frontage. 90 foot rear width. Each parcel has to maintain a 15,000 square foot minimum. With all of these requirements, plus we have the existing wetland setbacks. With all of these things we no longer have the flexibility that we were hoping for. We attempted to find some ways to meet the intent of the ordinance as well as facilitate this development and do our best to preserve the site. One of the options that worked best for the site would be to rezone the site to a medium, a planned unit development with an underlying zoning of medium density. A planned unit development would give us all the flexibility that we need. If we went with a planned unit development low density. Again we're back to the 15,000 square feet and our hands are tied. We don't have this flexibility that we are trying to achieve. We contacted the DNR, Department of Natural Resources and we tried to explain the situation. Familiarize them with the constraints of the site and one of the solutions that the City recommended to the DNR and talked about with them was re -guiding the property to medium density. Under our ordinances there is no minimum lot size under the medium density. If there is no minimum lot size, that will give us the flexibility that we need but at the same time we needed to make sure that we don't exceed the 4 units per acre. In order to achieve that we went with a planned unit development which allows us to draft an ordinance that dictates how many parcels you can have. What is the minimum lot size and the City will be able to achieve what this, what the intention was to develop this site. So with the subdivision, again 16 single family lots. Setbacks will be 25 feet front yard and 30 feet minimum in the rear. All of the parcels and the structures will have to maintain required setbacks from wetlands as well as have a wetland buffer. Minimum lot area on these, or minimum hard surface coverage on these parcels is actually 30%. The applicant submitted some house plans that could potentially be developed on these parcels. Not all of the house plans would fit on each parcel. Some of them such as Lots 1, 2 and 3, Block 1, there's only one house pad from what the applicant gave us that would fit on those. One of the other concerns was, as the developer builds the home and then the City is continuing to deal with homeowners, will they ask for a large patio than what the parcel can handle so to get to, to address this point staff listed under the 23 Chanhassen Planning Commission —July 16, 2013 ordinance, the planned unit development ordinance which will govern this development, we listed the maximum hard surface coverage permitted on each parcel. These are the homes that the applicant is proposing. Two car garage and they range, the homes range in size. In width between 50 and 60 feet depending on the type, depending on the parcel that we will be looking at. The setbacks currently under our planned unit development ordinance requirements, this development would need to maintain a 50 foot setback along the perimeter and the applicant would be able to meet all of these requirements with the exception of the area along Highway 212. There will be a wall that will separate this development from Highway 212 and that will be an adequate buffer. This setback is a buffer so it's a double buffer if you will in this case and staff is recommending that the setback variance be approved. Another variance that is requested with this development is the length of this cul-de-sac. The city code limits the length of a cul-de-sac to 800 feet. This one exceeds that, that length and typically we look at situations like this and say, will this road, if connected, how will it connect and we really have no way of reconnecting it. Looping it with 86th Street nor with Tigua Lane. Staff is recommending approval of the length of this variance as well. We address the rezoning of the site and explained why we are recommending approval of rezoning it to planned unit development. We also went over the guidelines and the ordinance that will govern this site. In order to allow this site to be a planned unit development with a medium density, the underlying zoning medium density, the zoning has to be consistent with the land use plan. The current land use plan guides this site for low density residential. The only, the planned unit development ordinance under the medium density specifically states that it has to, the land has to be guided medium density to allow that type of zoning so in order to stay consistent between the zoning ordinance and the land use map, and the land use we would need to amend the land use map. One of the benefits of rezoning the site to a planned unit development will be an extension of an existing noise wall and it will currently all there is, is a chain link fence and it is immediately next to a noise wall that is located between Highway 212 and the development to the west of the subject site which is Mission Hills. So again that wall will be extended along Highway 212. It will be within MnDOT right-of-way and there will need to be some agreements with MnDOT. All approvals would have to be granted in order for the wall to be built. At this point I would like to tum it over to Alyson with our engineering department to address drainage, grading and, before we go any further I just wanted to apologize. There was a section in the staff report addressing the grading that I failed to include. I have handed it out. It will be on the website and it will also be included in the staff report that will appear before the City Council. Aller: And for the record we have received a copy of the drainage and grading consisting of three pages. AI -Jaffa Correct. Aller: And it has been reviewed. AI -Jaffa The conditions will remain as is. They have been included. It's the discussion of the item that was omitted from the staff report. Aller: So again for everyone present or watching, this will be down on the website shortly so you can take a look at the discussion with regard to drainage and grading, if that's important to you. I know it's important to us so thank you. Fauske: Thank you Sharmeen. Staff just wanted to let the, show the Planning Commission what the drainage patterns are doing on this site. Under the current conditions as shown at the top here of the screen, the area outlined in purple currently drains to the north via the wetlands on the site and the area in blue here on the east side that drains to the east through the MnDOT right-of-way area and then to Rice Marsh Lake. Under the proposed development patterns the area in purple still drains to the north via the wetlands. This area, and I apologize if it's not really clear. This area where the arrow is going, they do show a proposed bioretention area. At this point they show it on the plan. Whether or not there's 24 Chanhassen Planning Commission — July 16, 2013 adequate separation from the proposed bioretention basin to the wetland elevation, we're unsure of if that would really function as that so for these purposes I did show it as draining to the wetland but that might change to a stormwater management facility. The area in pink indicates all the area on the site that drains to a pond that will be constructed with the development. There are two ponds proposed. One is a small pond on the southwest comer of the site and then the larger pond over on the east side of the site. And there again there's this area on the east side that would drain to the east side. Also of note is just the way the lay of the land and unfortunately we're not able to change the grades enough to be able to get this small sliver here. It's about 200 feet of street that would drain onto Tigua untreated and within the development ponds and one of the conditions in the staff report states that we need to get an analysis of that because there's, the current stormwater system on Tigua, from our observations and from what we've heard is at capacity and so we want to see if there's something that can be done to provide something like an inline treatment. Some kind of inline attenuation to prevent that peak discharge from going to the existing storm sewer system. Also in the staff report, with the hydrology analysis that was done, a section of the city code requires that the peak discharge rates for a proposed development cannot exceed the current conditions. In the discussion that we've had with the developer is that it's at each discharge point. So for example on the proposed condition here there's an existing peak discharge point at this location and at this location and under the proposed development conditions, depending on the type of event you're looking at, whether it's a 2 year event or a snow melt event, there is some peak discharge rates that will be exceeded. That being said there are some, in our review of the hydrology calculations that were done on the site, the developer's engineer had assumed 32% impervious on the home sites so taking that down to the 30% maximum that's allowed, we're not sure if that, it will certainly help. We don't know if that will bring it into compliance but that remains a condition of approval for the proposal. And in addition to, where those discharge points lie is there's a 12 inch culvert at this location and an 18 inch culvert at this location that would need to be included in the model because again there are concerns about the existing drainage patterns through that site. There's a ditch along the northern property line that is, after the rainy season that we've had this year has been flowing full so we want to make sure that, that there's some capacity there under the proposed development conditions. Additionally we talked to the developer about some concerns with some of the ground water. When the soil borings were taken there wasn't any ground water encountered at that time but with the way the drilling operations go, they put the drill down. They get the samples of the soil. They tell us what kind of soil they've encountered. They look and see if there's water present and then they back fill. The developer at these, these are the approximate locations but has installed pedometers to provide us with some ground water elevations and so he's provided between 4 and 5 readings for the site and so we have seen some ground water elevations come up and stabilize and so the developer's been working with us to adjust the low floor elevations of the adjacent homes so that there's 3 feet of separation. The reason we want to have a separation from that ground water to the lowest floor is, even if you do have a sump pump, draintile system, power failures, your sump pump fails, we want to provide that extra assurance for a property owner that there's some separation through there so that's why we're so closely monitoring these ground water elevations. Additionally one of the things, and it's just the nature of soils, we don't know what will happen but the area on the east side of the site here where the proposed pond is, is in close proximity of this boring 14 which has shown some higher ground water elevations. The pond area is actually will be about 12 feet of cut so I'm not sure if the ground water that's present in boring 14 will find it's way to that cut area. We're not sure but we did include that as a point of discussion in the staff report that if that's the case the pond design would not function as it is because it's not assuming a ground water flow into the system. So that's another element that unfortunately with the nature of soils is kind of a wait and see situation. The other element I would like to talk to you a little bit about is the wetlands. As Sharmeen had indicated there's a wetland alteration permit application along with this subdivision request. The area shown here in red is at the roadway location and that impact is shown at a location that the roadway design situated so that it would minimize that wetland impact. "There's just due to the site constraints unfortunately that's an impact that we just don't see as avoidable. Another impact that's shown on the proposal is that the cul- de-sac there on the very tip of the wetland here on the east side of the site. That impact, as indicated in Nk Chanhassen Planning Commission — July 16, 2013 the staff report, is avoidable if the trail moves to the north side of the street. The grades coming off of the road there could be adjusted so that that impact would go away. The trail would also move onto the side of the street where the homes are. There would be some snow storage provided at the cul-de-sac there next to the wetland so those are some reasons, some other reasons besides the wetland impact to look at relocating that trail to the north side. Additionally when you look at having that trail on the south side of the road, I apologize this isn't working. The future trail extension, there we go. The future trail extension to the east would also have an impact at this location. You know there's an opportunity to put, if there was a boardwalk in that would minimize the impact but that's an additional cost. There's also the high flows through the wetland, will that impact so those are all things that through the analysis, that was why the wetland application was denied based on the trail location so the condition of approval as stated in the staff report is to move the trail to the north side. Al-Jaff: Staff is recommending approval of this application to include a land use plan amendment, a rezoning, a subdivision, variances, site plan review and a wetland alteration permit with conditions. Again this has not been an easy site. We have been working on it for a very, very long time and I'm going to back track just one moment. There is a possibility, there is a way to achieve the 15,000 square foot lot area but that would mean extending lot lines into the wetlands. That is not what we want to end up with. Often we have seen people say, well I own the wetland and I can make some alterations so our intention is to preserve the site and again staff is recommending approval of the application and with conditions and we'll be happy to answer any questions. Aller: I think that report was very thorough for my purposes so I don't have any questions. Withrow: I have a question with regard to the comprehensive park plan. Is that an open issue to compliance? I'm just reading the staff report it indicates that the site is too far away. Al-Jaff Correct. One of the, we talked to the Park Director about this item and one of the things that they suggested was there is no place for an actual park within the immediate area. The trail, the sidewalk will connect to a trail and that trail is a regional trail. It will go underneath Highway 212 and will connect with the park along Lake Riley Boulevard and Lake Riley. I know I'm not answering your question but there isn't a park within the immediate area or a place to have one. Aller: I think that answers Hokkanen: Well I have a couple questions. Are we trying to squeeze too much into one space? What if we had one less lot in that span, would that create some of the, I mean there's so many conditions in, would that help? A]-Jaff: Any time you reduce lots, yes it will but it's a matter of can they meet the conditions of the ordinance that the City would be adopting and it's up to the applicant to demonstrate that they can do that. Aanenson: Can I just clarify that? We went through this in the preliminary. To get to medium density zoning you meet the minimum which is 4 units an acre which also is the maximum for low density so when we went through this in the preliminary process, because some of the size actually are four, four does allow for twinhomes which is a minimum lot of 10,000 square foot lots so we probably could do some twinhomes in there so looking at that, those are some of the factors that we went into ... 4 units an acre but that was the goal. AI-Jaff: As it is right now we are exactly at 4.002. Aanenson: Yeah, so then you weren't meeting density requirements. 26 Chanhassen Planning Commission — July 16, 2013 Hokkanen: Another question. The variance for the 800 length of the cul-de-sac, do we have another long cul-de-sac or multiple ones in Chanhassen? Aanenson: Highover. There's a few of them. Hokkanen: Right. Okay and then the curve with the 40 miles an hour, can you explain that? Fauske: Certainly. At this location the street design would not meet a 30 miles an hour design curve and so we just would require an advanced warning sign. The yellow caution sign so that drivers would know that it's not 30 miles an hour and they would have to slow down. And again that design is dictated based on the constraints of the site with the wetland and then the proximity to the 212 corridor. Aller: The cul-de-sac, has it been determined that that will safely handle the fire truck if needed? Fauske: The cul-de-sac is our standard diameter cul-de-sac and the cul-de-sac length, the reason we had included a limitation on the length in the city code is to limit the number of units on a cul-de-sac so that if there was an emergency where the access was cut off you would limit the number of residents that were inconvenienced by that. In this situation there is a ... supporting the variances. You have the first, I think it's 500 feet of the street does not have any homes on it and then you have a one sided benefit to the street for another 500 feet or so, so that's why we support that variance. Yusuf: So how long does this cul-de-sac end up being? Al -Jaffa 1,300. Yusuf. Did the staff consider having two accesses here? Maybe like a ring road with an access to, is it Tigua Lane? Fauske: When we look at that then we, there would be additional wetland impacts and we would not meet the sequencing requirements of minimizing impacts so that's a very good question. That was one of the reasons we didn't look at looping the street back. Yusuf: Thank you. Aller: Okay, which leads to the conditions as stated in the report and that we approve tonight would mandate that those sequences be met. Anything else? The applicant said he would like to come forward. Welcome sir. John Knoblauch: Good evening. I'm John Knoblauch, 1450 Knob Hill Lane, Chanhassen. We're the applicant and developer and this project, we started I think sometime in April or May of last year and very many drawings have been done. Staff has worked diligently to try to put their best foot forward to develop this parcel. We feel this is the best use of this parcel. A couple of pluses, we have hired Shirley Walker, an engineer that did the sound walls for 212 and she is working with MnDOT on the sound wall. Noise wall and that will be a huge asset for all the neighbors in that Mission Hills area and everybody to the north and also to the west. Part of the sound wall in what we call the hole is going to be about 20 feet high and there's a lot of noise that rides through that hole on the south side so that's going to dramatically help many of the neighbors far reaching from this development. The wetland, you know the main wetland is a Type 3 wetland. The two wetlands on the southeast there are Type I wetlands and both the wetland delineator and Terry, the LGU here in Chan has said that both, well especially the one next to Lot 1, Block 2 there, it's a very poor quality wetland. It's a seasonal wetland. It's got sumac in it and so we 27 Chanhassen Planning Commission — July 16, 2013 have a recent drawing that was just delivered to the City here I believe maybe 2 days ago where we've moved that cul-de-sac just a little bit and we've tweaked it to the north and we've also put a very small retaining wall, about a 35 foot retaining wall along the sidewalk. It's 2 to 3 feet high and that will completely eliminate that little red, what we call the point impact so we will actually not have any impact on that wetland and where you see the orange stripe for the, when it turns into a trail. By the way I'd like to define the, Alyson referred to it as a trail. I just want to make sure that the, on the drawings that are out there right now, all the way to the end of the cul-de-sac is a regular sidewalk so it's a regular 5 foot sidewalk. The 8 foot blacktop trail would start at where the road would, the cul-de-sac. So we're able to have no impact there. With a boardwalk we can cross that area between those two wetlands and have zero impact. Totally allowable with the LGU. I talked to him today and that would be an application that would be totally allowable and have zero impact. What I would like to see which would be smarter for the city of Chanhassen, and unfortunately we can't get to our laptop up right now but these two wetlands, the delineators that worked on these two wetlands, I'll go over and talk over here louder. In this area, right in here, this is basically, when this wetland has a bump it eventually flows over into this wetland and then eventually it goes through this area and dumps down into here and then goes north into Rice Lake. We are proposing the trail to go here. I know staff has talked about trying to put it on the north side to avoid this impact. We have not come up sequencing wise with a good way to get the trail to come through this area. Between this wetland and the ponding we need to do it's become very, very difficult to lay out. If I have pictures of this and really if you go out there, this has trees in it. It literally does not look like a wetland. It was really delineated, in my opinion as a convenience because the two were so close but if you walk out on the property this is very, very high ground right here. In my opinion, and also my wetland delineator which is Mike Gram from Wenck and also my engineer has said that if the trail were to go through this way, we would deal with a lot of ice and this is about a 6 foot drop that would go inbetween this V and then come back up. So in other words we either deal with a culvert, a much more problematic here or we deal with a much smaller culvert here and my suggestion just for maintenance is that somehow staff works, that we just try to avoid this wetland as much as we can. That staff tries to work it out that we're able to bank this area and put a culvert in here and have this blacktop. 8 foot through this area and the reasoning for that is maintenance so that your crews can get a snowplow back here and so forth so that's just some of my suggestions. We don't really know any other way to get the trail over to hook up to the new 3 mile connection which is the parks department's main goal. I wanted to show the National Wetland Inventory Map around Rice Lake Marsh. If you go to the National Wetland Inventory and you goggle it, right now the existing trail that goes around Rice Lake Marsh, there's about a mile and a half that's finished on the north side, as most of you maybe have walked it, and we're going to be, we would be a final link on the south end of Rice Lake that will eventually go through the MnDOT property. Right now about a mile of that trail goes through a PEMA wetland area according to the inventory. According to the National Inventory, there is no wetland between these two and so I would like, if you get a chance to pull that up and get a grip on the 3 mile trail because the wetland impacts that have been done on that existing trail are unbelievable. It's beyond what I could ever imagined. When I started to look around and really see what this trail was to do to this project, I just think it's miniscule in the realm of the overall trail system that's going to be put in. So we would like to see the trail stay where it is on our drawings. And the other thing is, most of the reasoning is that the trail will be just that more enjoyable. Walking between houses, we have a trail over at Knob Hill like that. You know it's looking in people's windows and you know up against a fence on a trail versus you know walking along a beautiful wetland, it's just a much more pleasant experience. And also the ground on the, along the MhWT right-of-way is higher. I think there'll be a lot less maintenance issues on that ground versus the ground that's to the north so our trail's all busted up right now from the heavy clay that we have in Chan and I'm pretty convinced that the soils are better the closer you get to the MnDOT right-of- way for that trail. So those are a couple of my comments as far as the trail location if this came to fruition and got approved, I'd like Planning Commission to look hard at that and possibly would be willing to visit the site and walk it to show you what we've got in mind with the trail. Thank you. in Chanhassen Planning Commission — July 16, 2013 Aller: Thank you. Questions? Okay, I'm going to open the public hearing. Any individual wishing to speak for or against the item, please step forward. Welcome sir. Troy Kakacek: Thank you. Troy Kakacek, 380 West 86h Street. I am right across the street from where the development's going. I guess I only have one clarification or question is, so as part of the, because there's multiple variances being requested here. So as part of the change, the zoning change from the single family, or residential single family to the, what's the zoning? Sorry. AI-Jaf£ Planned unit development. Troy Kakacek: The planned unit development. So as part of that and changing it from low to medium it all kind of, it's a package deal is kind of what I'm getting at so if we approve, if it's approved to do the plan and then the PUD eventually falls through like the plan itself, is it now considered medium density property for other uses outside of this current PUD? AI -Jaffa There is, as a condition of approval we have made a contingency so approval of the rezoning is contingent upon approval of the subdivision. Troy Kakacek: The subdivision, okay. And then okay, perfect. And then the subdivision currently sits, I couldn't see the current plans for the homes but they're all, the 16 lots are all single family detached homes? Al -Jaffa Correct. Troy Kakacek: With, I don't know what the square footage approximately was but I think they were all included in there and I couldn't read it, it was too small but so with that I'm very much for the single family homes. My only, you know my concern with how much is going into this approval. There's a lot going on so it is just no more townhomes in that area because it's all single family to the north and through Mission Hills so it's really, and it's a very quiet dead end road so with townhomes that would bring in significant traffic and also with the drainage that we're already kind of talking about. That would add to the drainage problems in that area through, because all of the current townhomes to the, it'd be the west drain down to that holding pond so everything, if it rains hard now it's kind of like a river going through my front yard. So I'm fine with single family, or for single family. Not for any change if this PUD does not go forward. Thank you. Aller: Thank you. Any additional comments? Welcome. Karen Blenker: Hi. I'm Karen Blenker and I live at 405 Rice Court and that backs right up to the road. The proposed road and the reason I bought my place was because of privacy and because of that wooded area and the wetland and you know I paid $5,000 more for that townhome compared to the exact same thing on the other side of the road so what is that going to do to the property values? And then also what is it going to do to the wildlife out there? And the wetlands and you know people putting chemicals on their lawn and it's draining into the wetlands and I guess I, I think we should preserve these areas, especially with all these wetlands and you know get back to the way of life and give back to nature and you know keep these areas the way they are so I guess that's my opinion. Aller: Thank you. John Knoblauch: Two comments I thought about was the one is that Knob Hill Lane where I live in the north part of Chanhassen, we're at 1,250 foot on our cul-de-sac. This is about 50 foot longer than Knob Hill. Secondly, we own about, how maybe wetlands do we own Joe out in western Minnesota? You 29 Chanhassen Planning Commission — July 16, 2013 know we have no intention of doing any damage to these wetland areas. All the wetland areas have a 30 foot buffer on the Type 3. Is it 25 or 30? AI-Jaff It's a 30 foot setback plus 16 1/2 foot average buffer. John Knoblauch: Okay so, we're hoping that there's a lot of filtration there before any lawn issues would come up and so we're pretty confident that with these buffer areas that are set up, and the rezoning provides for that, that these yards won't have a ton of impact. You know the nice wetland that's there, I think the wildlife will not change that dramatically. There's a few deer that live in there and the areas to the, especially to the east because that whole property to the east is actually going to be left fairly wild from the cul-de-sac to the east where the pond is and then over to the MnDOT property. Unfortunately this drawing really makes it look like we're, I don't know if there's another drawing but it looks like we're kind of building some lots inbetween a lake on an island. If you walk out on the parcel, this was a farmed parcel for years. They farmed right through those two blue wetlands to the southeast and he has a cattle walkway where the road is now and we encourage anybody to go out and take a walk back there and I think it will be a really nice site. One thing that I would also mention is that the homes that I've built in Shakopee for the last 17 years, we've been building on lots from 8,500 to 9,200 square feet and those homes are 2,700 to 2,900 square foot, two stories and these pads are actually bigger, believe it or not than those at 10,000 square feet and so if you think about it, the buildable area in this, on this drawing up here is 4 acres. It's an even 4 acres. Now keep in mind this site is 13.62 acres. Okay so that gives you a perception of really what's out there. I think this is the best thing that could come along rather than twinhomes. There was a couple twinhome plans that were looked at, that we looked at trying to do, and we still think this is the best scenario. Thank you. Aller: Thank you. Any additional individuals wishing to step forward? Yes ma'am. LuAnn Markgra£ I'm LuAnn Markgraf I live at 401 Rice Court. I would be the first townhouse unit that would be impacted by the entrance, and there's lots of trees and oaks right in the back of my unit and how much of that, is all of that going to disappear? And is it going to be looking at a sidewalk? Is there going to be a retaining wall? What is going to happen with that area? I noticed that there is going to be a street sign that is going to be going in that comer. In relation to that map, where is the sign going to go? So those are my biggest issues. Because it is a very quiet area and it's going to be impacted by you know more cars. They'll be having that speed limit sign up for people to show how fast they're going through there because people speed through there on 86" now as it is. So there's a lot of issues, and granted they live in a townhouse. Don't live in a single family home which I think John kind of, the last meeting last winter it was like oh the real estate market for the townhouses has just gone down the tubes. We don't really care about townhouses. What we care about is getting as much, as many units in that area as possible and not care about the townhouses that face the entrance and the only one entrance to this development, which is a big issue. So that's my comments. Aller: Thank you. John Knoblauch: May I address one? Aller: Sure, that would be great. John Knoblauch: Yeah, I've been well aware there's about 6 significant oak trees Aanenson: Mr. Chair, I'm sorry but we're having a difficult time hearing... Aller: Why don't you come up. 30 Chanhassen Planning Commission — July 16, 2013 John Knoblauch: Okay. Aller: Thank you. John Knoblauch: Yep, and backing up to their four, I believe it's a four isn't it? LuAnn Markgraf: Four units. John Knoblauch: Yeah the four unit, there is some significant, in the tree survey, I believe there's about 6 oaks there and my understanding is those will not be touched. They're pretty tight to the townhome property. One plus that I heard from one of the townhome owners is that right where the road is proposed there's 3 huge cottonwoods that basically clog their air conditioners every year and those 3 big cottonwoods would actually come down but the intention is the berm that's there now, next to the town, there's kind of a natural berm that comes up and the oaks that are on that are going to remain. Thank you. LuAnn Markgraf: What about the sign? Al -Jaffa There is a sign that is shown on the plans that is proposed to be located at this corner, which would be a southeast comer of the intersection of West 86"' and the proposed road. Staff is recommending that it meets all ordinance requirements pertaining to wetland setbacks, wetland buffer, property line setback, which would be 10 feet. It cannot be within sight distances and the area of the sign cannot exceed 24 square feet nor 5 feet in height. Aanenson: I just want to make sure we're talking about a development sign, not a stop sign Al -Jaffa Correct. Yes. John Knoblauch: We would like to do a stone for a sign. It's very, very small spot. It's a very small window on that front corner. I want to call it the southeast corner of the intersection. It looks like it'd be doable to get a stone, you know engraved stone. We don't have any intentions of having any large, you know some kind of a monument or anything. It would be pretty minimum for signage but it looks like there's a small spot there. We would like it on that side. Opposite of the townhomes. Thank you. Aller: Any other individuals? I will close the public hearing. Comments, questions. Hokkanen: Very thorough report. Yusuf: I don't have any questions. Aller: If we were to look at the, is there a way to leave open alternatives? I don't think there is. Aanenson: Well what I would suggest Mr. Chair, members of the Planning Commission is that you direct your motion and but maybe you can also direct staff to work between now and City Council to consider some of those alternatives to present to the City Council. You could word it such that ... if you wanted to approve it going that direction but consider the following things between now and then. Aller: Okay, and this is now ... to the commissioners. We've got the potential application of the sidewalk which I'm fully in favor of and the whole idea of a PUD is that the City gets certain things out of a PUD that it normally wouldn't under the zoning and that's the purpose of changing it. And so that would be one of my goals is to make sure that the City and the desires of the City to protect that wetland and those 31 Chanhassen Planning Commission — July 16, 2013 buffers is effectuated so I'm all for going ahead because I think there are enough protections here to vote in favor of moving forward the way it has been presented by staff but my thought is that if Terry and Water Resources and staff come up with a better plan, I don't want to forestall that and I don't want to have them need to come back so that would be my thought. Hokkanen: No, I agree. Aller: Because there are a number of conditions that we will be waiting for to be met as far as numbers to be crunched and water tables and things that would impact that specific requirement. So with that any other questions or comments? Withrow: No. Aller: I'd entertain a motion. And you add that in there... Hokkanen: Okay. Okay, the Chanhassen Planning Commission recommends approval of the Land Use Map Amendment from Residential Low Density to Residential Low and Medium Density. Rezoning from Single Family Residential and Mixed Low Density Residential to Planned Unit Development Residential. Subdivision of 13.22 acres into 16 lots and two outlots with variances. Site plan review and Wetland Alteration Permit subject to the conditions of the staff report and adoptions of the attached Findings of Fact and Recommendation including further review of the location of the trail within the wetlands. Or future recommendations of proper placement. Aller: That being a motion, do I have a second? Yusuf. Second. Aller: Any further discussion? Hokkanen moved, Yusuf seconded that the Planning Commission recommends the City Council approve the land use map amendment from Residential — Low Density to Residential — Low and Medium Density with the following condition, and adoption of the attached Findings of Fact and Recommendation: 1. Approval of the Land Use Amendment is subject to Metropolitan Council determination of consistency with system plan. All voted in favor and the motion carried unanimously with a vote of 4 to 0. Hokkanen moved, Yusuf seconded that the Planning Commission recommends the City Council approve the rezoning from Residential — Low Density (114) and Mixed Low Density Residential (R8) to Planned Unit Development — Residential (PUD -R) with the following condition; and adoption of the attached Findings of Fact and Recommendation and attached ordinance rezoning the property. 1. Approval of the Rezoning is contingent upon approval of the final plat and execution of the development contract. All voted in favor and the motion carried unanimously with a vote of 4 to 0. 12 Chanhassen Planning Commission - July 16, 2013 Hokkanen moved, Yusuf seconded that the Planning Commission recommends the City Council approve the preliminary plat to subdivide 13.22 acres into 16 lots and 2 outlots as shown in plans dated received June 14, 2013 with the following conditions, and adoption of the attached Findings of Fact and Recommendation: All lots must comply with the following table: COMPLIANCE TABLE Wetland setback: 20 ft. buffer, 30 ft. principal structure, 15 ft. accessory structure.

All relocated trees shall be warranted for two seasons and replaced by developer if dead or dying within that time period. 3. The applicant shall show proof to the city of permission by MnDOT to place landscape materials on state right-of-way. 4. The applicant shall increase bufferyard plantings along the south property line to meet minimum requirements. 5. Advanced warning and speed advisory signs are required where the design speed is less than 30 mph. 6. The site plan and HydroCAD model must be revised to address the following comments: a. Peak discharge rates are proposed to increase at the following locations: i. Runoff leaving the overall site for the two-year (2.8 -inch) rainfall and snowmelt events. ii. Runoff leaving the wetland located on the western portion of the site for each design event. iii. Runoff leaving the site to the north for the snowmelt event. b. Use a pond in the model at the 18 -inch culvert located north of the site. c. The analysis should reflect any overtopping of the driveway or other overland flows that may occur. d. Due to the increased velocities through thel2-inch culvert leaving the western wetland, the developer must provide a design to address associated erosion at this location. Any required improvements outside of existing easements shall require additional easements. e. The drainage areas and/or curve number in the HydroCAD model must correspond to the Drainage Area and Curve Number Table. £ Directly connected impervious areas must be modeled separately rather than included in the composite Curve Number computation. g. The applicant must provide calculations (or submit a model) demonstrating that the city's requirements for water quality are satisfied. i. If the event -based NURP standard cannot be achieved by dead pool storage, then (P8 or other) calculations should be based on equivalent annual removal efficiencies. ii. If an iron -enhanced filtration system is included in the design, calculations should be provided demonstrating the water quality treatment benefits of the BMP. Detailed plans of the system should be submitted for review with the calculations. 34 Chanhassen Planning Commission — July 16, 2013 iii. The report notes that the east pond is able to remove 87.8% of the phosphorus load. This removal efficiency appears excessively high. It is anticipated that there is either an error with the model inputs or the calculation was performed for a particular rainfall event rather than annualized removal efficiency. 7. The HydroCAD model must be revised so that the impervious surface of the lots is 30%. 8. If groundwater is encountered during site construction the lowest floor elevations must be adjusted so that there is a minimum three-foot separation. 9. The developer must provide additional information showing how the proposed "Preservation/Stormwater Volume Reduction Area" between the large wetland and the back of Lots 4-7, Block 1 will meet the minimum requirements. 10. Storm sewer sizing calculations must be submitted with the final plat application and shall include the existing storm sewer at Tigua Lane (approximately 280 feet east of the proposed street intersection). The existing 12 -inch reinforced concrete pipe north of Lots 7 and 8, Block I shall also be included in the analysis. 11. The grading plan must be revised to address the following comments: a. The developer must obtain a MnDOT permit for the proposed grading within the MnDOT right-of-way. b. The grading plan must be revised at the slope down from the street to the wetland at Station 3+00, and between Lots 3 and 4, Block 1 so the slope does not exceed 3H:1 V. c. The lowest openings of Lots 2 and 3, Block 2 must be at least one foot above the emergency overflow elevation. d. The minimum floor elevation of Lots 8, 9 and 10, Block 1 shall be 897.6'. e. The building envelope for Lot 3, Block 2 must not encroach into the drainage and utility easement. f. The side yard drainage and utility easements between Lots 10 and 11, Block 1 must match what is shown on the plat. g. The building pad shown for Lot 1, Block 2 cannot accommodate any of the house styles provided and must be revised accordingly. h. It is difficult to discern between the proposed contours, lot lines and setback lines. The developer's engineer is requested to change the drawing line weights. 12. A building permit is required to construct the proposed retaining wall. Plans must be submitted with the permit application and must be signed by an engineer registered in the State of Minnesota. 35 Chanhassen Planning Commission — July 16, 2013 13. Some homes may choose to install a privately -owned and maintained booster to provide a higher water pressure. 14. The watermain shall be 8 -inch PVC (C-900). 15. Prior to final submittal the developer must obtain the necessary easement to install the sanitary sewer off-site, to the north. 16. A portion of the trunk sewer and water hookup fees must be paid in cash with the final plat in the rate in effect at that time. 17. Street and utility plan and profile construction plans must be submitted with the final plat. 18. The Surface Water Pollution Prevention Plan (SWPPP) must be prepared as a standalone document and submitted to engineering for review and comment. This SWPPP shall include a narrative, plan set and applicable details. 19. The SWPPP must include the required elements as listed in Part III of the National Pollution Discharge Elimination System General Permit Authorization to Discharge Stormwater Associated with Construction Activity (NPDES Construction Permit) and in the MPCA SWPPP checklist. 20.

PUBLIC HEARING: 9150 GREAT PLAINS BOULEVARD: REOUEST FOR VARIANCE TO ALLOW AN ALTERNATIVE TO A SUBSURFACE TREATMENT SYSTEM (SSTS) ON PROPERTY ZONED AGRICULTURAL ESTATE (A2) AND LOCATED AT 9150 GREAT PLAINS BOULEVARD. APPLICANT: CITY OF CHANHASSEN. PROPERTY OWNER: JAMES D. WILSON, ET. AL, PLANNING CASE 2013-14. Aanenson: This is the Wilson Nursery piece. This is a request for a variance in the City Code to allow the installation of a sewage ... on property zoned Agricultural. The subject site is 38, I mean 39 acres and is seasonally used as a nursery site. It's guided low density in the 2030 Comprehensive Plan. This is the location of the subject site. Again it's almost 39 acres. It abuts Highway 101 where it just so happens that the City is doing an improvement project. This is kind of the engineered drawing of the improvement project. ...but as they were working in the, what they believed was the easement, existing septic site was in that easement area and was not... so it was accidentally hit so if you look at this map, which would be a little easier to read then the engineering plan ... it's right on the easement area so it was hit. ...so the resolution that we're proposing with this variance request is to put a holding tank in there. The City has adopted Carver County's ordinance for holding tanks and that's what we're referring to here so the recommendation would be to replace it with a holding tank so it has to be pumped regularly. We feel comfortable with this use as this, the Wilson Nursery property because it is a seasonal use. So no one's living there. It's used as part of the operation. The reason why another septic site could not be placed on this site is that the entire area's been compromised through the activity that's taken place with the landscaping business and then the ultimate grading of that right-of-way for the City's... There wasn't a good site to put that so this is in a future growth area. We do believe that within the next number of years they could potentially redevelop. Basically a lift station built off of Powers Boulevard immediately to the west of this property bringing sewer up ... but we do believe that is coming in in the near future so the staff 38 CITY OF CBANNA33EN 7700 Market Boulevard PO Box 147 Chanhassen, MN 55317 Administration Phone: 952.227.1100 Fax: 952.227.1110 Building Inspections Phone: 952.22T1 180 Fax: 952.227.1190 Engineering Phone: 952.227.1160 Fax: 952.227.1170 Finance Phone: 952.227.1140 Fax: 952.227.1110 Park & Recreation Phone: 952.227.1120 Fax: 952.227.1110 Recreation Center 2310 Coulter Boulevard Phone: 952.227.1400 Fax: 952.227.1404 Planning & Natural Resources Phone: 952.227.1130 Fax 9522271110 Public Works 7901 Park Place Phone: 952.227.1300 Fax: 952.2271310 Senior Center Phone: 952.227.1125 Fax: 952.227.1110 Website www.ci.chanhassen.mn.us MEMORANDUM TO: Todd Gerhardt, City Manager FROM: Sharmeen Al-Jaff, Senior Planner DATE: July 28, 2014 0� SUBJ: Preserve at Rice Lake Final Plat Approval — Planning Case 2013-12 PROPOSED MOTION "The Chanhassen City Council grants approval of the final plat for Preserve at Rice Lake as shown in plans dated received June 13, 2014 and subject to the conditions of approval in the staff report."

All relocated trees shall be warranted for two seasons and replaced by developer if dead or dying within that time period. Finding: This condition has been modified by adding the following language "All relocated trees shall be warranted for two seasons and replaced by developer if dead or dying within that time period. All overstory trees must be a minimum of 2.5" diameter and all understory trees must be a minimum of 1.5" diameter or 6' height." Advanced warning and speed advisory signs are required where the design speed is less than 30 mph. Finding: This condition still applies. 4. The site plan and HydroCAD model must be revised to address the following comments: a. Peak discharge rates are proposed to increase at the following locations: i. Runoff leaving the overall site for the snowmelt events. Finding: This condition still applies. ii. Runoff leaving the western portion of Wetland A for the 2, 10 and 100 year design events. Finding: This condition still applies. iii. Runoff leaving the site to the north of the eastern portion of Wetland A for the snowmelt event. Finding: This condition still applies. iv. Runoff leaving the site to the north of the western portion of Wetland A for all events. Finding: This condition still applies. b.

Directly connected impervious areas must be modeled separately rather than included in the composite Curve Number computation. Finding: This condition no longer applies. Mr. Todd Gerhardt Preserve at Rice Lake — Planning Case 2013-12 July 28, 2014 Page 4 of 21 d. The applicant must provide calculations (or submit a model) demonstrating that the city's requirements for water quality are satisfied. Finding: This condition still applies. i. If the event -based NURP standard cannot be achieved by dead pool storage, then (P8 or other) calculations should be based on equivalent annual removal efficiencies. Finding: This condition no longer applies. ii. If an iron -enhanced filtration system is included in the design, calculations should be provided demonstrating the water quality treatment benefits of the BMP. Detailed plans of the system should be submitted for review with the calculations. Finding: This condition no longer applies. iii. The report notes that the east pond is able to remove 87.8% of the phosphorus load. This removal efficiency appears excessively high. It is anticipated that there is either an error with the model inputs or the calculation was performed for a particular rainfall event rather than annualized removal efficiency. Finding: This condition no longer applies. 5. The developer shall obtain off-site easements over the existing swale and 18" culvert. Finding: This condition no longer applies. 6. The developer agreed to replace the 18" culvert north of the site with a new pipe that provides the same capacity. Finding: This condition still applies. 7. The HydroCAD model must be revised so that the impervious surface of the lots is 30%. Finding: This condition no longer applies. 8.

Finding: This condition no longer applies. 17. Plan shall show proposed pond maintenance access and landscaping must not interfere with pond maintenance access. Finding: This condition has been modified to read "An easement for trail and pond maintenance access between Lots 11 and 12, Block 1, must be filed with the final plat." 18. The applicant must apply for and receive an NPDES permit from the Minnesota Pollution Control Agency and provide evidence to the city prior to grading the site. Finding: This condition still applies. 19. The Surface Water Pollution Prevention Plan (SWPPP) must be prepared as a standalone document and submitted to engineering for review and comment prior to final plat approval. This SWPPP shall include a narrative, plan set and applicable details. Finding: This condition has been met. 20. The SWPPP must include the required elements as listed in Part III of the National Pollution Discharge Elimination System General Permit Authorization to Discharge Stormwater Associated with Constriction Activity (NPDES Construction Permit) and in the MPCA SWPPP checklist. Finding: This condition has been met. 21. A detailed erosion prevention and sediment control plan must be submitted for review and approval per the requirements of Section 19-145 of Chanhassen City Code and the NPDES Construction Permit. This should include, among the other listed requirements, all temporary and permanent best management practices. Finding: This condition has been met. 22. There is significant evidence of gully erosion at both off-site discharge locations. Rates must be reduced below existing discharge rates or efforts must be taken to stabilize these discharge points to prevent further channel incision and head cutting. Finding: This condition still applies. 23. Wetland buffers are required around all wetlands on site. Extend buffer around wetland E. Finding: This condition still applies. Mr. Todd Gerhardt Preserve at Rice Lake — Planning Case 2013-12 July 28, 2014 Page 7 of 21 24. Wetland buffer must be extended through all disturbed areas.

Finding: This condition has been met. 26. Minnesota Department of Transportation right-of-way is outside of the City of Chanhassen's WCA jurisdiction as MnDOT is their own LGU. Chanhassen's review of wetland boundaries ended at the property limits. The applicant must get all appropriate approvals from MnDOT for work on the sound wall. Finding: This condition still applies. 27. The development must comply with the MN Rules Chapter 6120 and the DNR must issue their concurrence to this effect. Finding: This condition still applies. 28. Estimated Surface Water Management Connection charges due at the time of final plat are $69,983.50. Provide area of wetland buffer and preservation/volume reduction area after development to accurately calculate credit. Finding: This condition still applies. 29. Fifty -percent (50%) of park fees shall be collected in consideration for the dedication of Outlots A and B. The park fees shall be collected in full at the rate in force upon final plat submission and approval. At today's rate these fees would total $46,400 (16 lots X $5,800 per lot/2). Finding: This condition still applies. 30. Wetland nomenclature on plan set shall be amended to correspond with HydroCAD drainage report and wetland replacement application. Finding: This condition has been met. Mr. Todd Gerhardt Preserve at Rice Lake — Planning Case 2013-12 July 28, 2014 Page 8 of 21 31. The land owner and the selected contractor must provide a Landowner Statement and Contractor Responsibility for Work in Wetlands or Public Waters form to the City prior to working on the road crossing into the site.

Seeded areas within the outlots shall be established and managed according to guidelines and policies developed by the Minnesota Board of Soil and Water Resources as are available on their website. Finding: This condition still applies. 36. Construction of the 8 -foot wide neighborhood trail connection from the public street to the southeast comer of the property. Finding: This condition has been modified to read "Construction of the 8 -foot wide neighborhood trail connection from the public street to the southeast corner of the property at connection point to existing trail." 37. The applicant shall comply with all MnDOT requirements for any work within their right-of- way, i.e. noise wall, landscaping, etc. Finding: This condition still applies. The final plat contained 16 lots and 2 outlots which is consistent with the preliminary plat. Mr. Todd Gerhardt Preserve at Rice Lake — Planning Case 2013-12 July 28, 2014 Page 9 of 21 FINAL PLAT The applicant is requesting final plat approval to subdivide 13.22 acres into 16 lots and 2 outlots. The site is zoned PUD, Planned Unit Development and is southeast of the intersection of Tigua Lane and West 86'x' Street, and north of Highway 212. J Block 1 a 9 10 ♦ 7 11 6 12 5 2 4 2 91 2 3 4 •1 :-- = The density is 1.2 units per acre gross and 4 units per acre net after removing the roads, storm ponds, wetlands and park. The applicant is proposing to develop the site in one phase. The outlots contain wetlands, storm ponds and open space. The applicant intends to dedicate the outlots to the city. All lots meet the minimum area, width and depth of the zoning ordinance requirements. All lots are proposed to contain single-family homes. The applicant submitted several home designs they intend to build. Access is gained off of an internal road. There is a variance attached to the application that deals with the length of the cube -sac serving this development. This variance was approved with the preliminary plat. All of the proposed lots meet the minimum width and depth requirements of the Zoning Ordinance. Staff notes that the proposal is consistent with the Comprehensive Plan and consistent with the Zoning Ordinance, with the recommended conditions. ROADWAYS The property lies north of Highway 212, east of County Road 101 and south of 86th Street. The proposed access on 86th Street is located so as to minimize wetland impacts. To further reduce wetland impacts staff supports a reduced right-of-way width (50 feet, with a 15 -foot front yard drainage and utility easement) and a reduced street width (28 feet) for the portion of the road that does not have any lots adjacent to it (approximately 400 feet). The remainder of the street and Mr. Todd Gerhardt Preserve at Rice Lake — Planning Case 2013-12 July 28, 2014 Page 10 of 21 right of way shall meet the City's minimum requirements. The proposed street curves do not meet a 30 mph design speed; advanced warning and speed advisory signs would be required. The proposed cul de sac is approximately 1,400 feet long, which exceeds the 800 -foot maximum length stipulated in the City Code. Based on the lot configuration and wetland conditions on the site, staff supports the proposed variance. DRAINAGE AND GRADING The developer hired Kallio Engineering to perform a hydrology analysis of the site. The study includes the off-site drainage from the west and north. Runoff from the eastern half of the street and the eastern lots is proposed to be treated in the proposed pond east of Lot 11, Block 1. A portion of the street is proposed to drain to the proposed pond in the southwest comer of the property. Runoff from the first 230 feet of the proposed street south of the intersection with Tigua Lane is not proposed to be treated on site. The developer's engineer that prepared the hydrology report has included this runoff in the analysis. The following comments pertain to the hydrology analysis provided by the developer: 1. Peak discharge rates are proposed to increase at the following locations: a. Runoff leaving the overall site for the snowmelt event. b. Runoff leaving the western portion of Wetland A for the 2-, 10- and 100 -year design events. c. Runoff leaving the site to the north of the eastern portion of Wetland A for the snowmelt event. 2. The applicant must provide calculations (or submit a model) demonstrating that the city's requirements for water quality are satisfied. The impervious surface of some lots may be at or near the maximum impervious coverage allowed once the home, driveway and required landings to exterior doors are constructed. Future home owners of these lots would have limited or no opportunities to construct other site amenities such as patios based on the plans provided. During pre -submittal meetings with the developer, city staff expressed concern of potential high groundwater elevations within the development. The developer responded by installing six piezometers on the site that allow for the measurement of static water pressures. Though groundwater was not encountered when soil borings were taken, groundwater is present in all piezometers. The developer's soils engineer took seven readings between May 1 and July 16, 2013. Readings were also taken on May 5 and June 24, 2014. Based on the readings from Boring #7 on May 5, 2014 the lowest floor elevation of Lots 1 and 2, Block 1 need to be adjusted to maintain three feet of separation from the groundwater. If groundwater is encountered during site construction the lowest floor elevations of adjacent lots must be adjusted to maintain minimum three feet of separation. Mr. Todd Gerhardt Preserve at Rice Lake — Planning Case 2013-12 July 28, 2014 Page 11 of 21 The developer proposes to mass grade the site. The developer must acquire any necessary permits from MnDOT for grading or drainage. It is difficult to discern between the proposed contours, lot lines and setback lines on the grading plan. The developer's engineer is requested to change the drawing line weights. UTILITIES A 12 -inch trunk watermain extends from the townhome development to the west to the Reflections development south of Highway 212. The property was assessed for this improvement. According to city records this assessment has been paid. The developer proposes to extend lateral watermain from this trunk line to service the development. Based on the proposed elevations of the homes, the operating water pressures within the homes will meet the minimum required per 10 States Standards; however, some homes may choose to install a privately -owned and maintained booster to provide a higher water pressure. The plan includes a water service to the property to the north of the plat located at 8591 Tigua Lane. This service will extend from the watermain within the cul de sac, through Lot 11, Block 1 and Outlot A. This service is not a public utility or a small utility (eg. gas, electric, phone); therefore, the platted side yard drainage and utility easement on Lot 11 is not the appropriate measure to allow for this water service. Upon consultation with the city attorney's office, an easement from the owner of Lot 11, Block 1, Preserve at Rice Lake must be recorded in favor of 8591 Tigua Lane to allow for the water service installation. This easement shall be recorded with the final plat. Additionally, an encroachment agreement is required for this water service as it will lie within the drainage and utility easement within Lot 11, Block 1 and Outlot A. The encroachment agreement shall be recorded against Lot 11, Block 1, and Outlot A, Preserve at Rice Lake with the final plat. The developer proposes to extend lateral sanitary sewer from the existing 8 -inch lateral sanitary sewer north of the site. Final plat approval shall be contingent upon filing the drainage and utility easement on the property to the north, 8591 Tigua Lane. A portion of the trunk water and sewer hookup fees (WAC and SAC, respectively) must be paid in cash with the final plat and are calculated as follows: WAC 16 units x $1,886/unit = $30,176 SAC 16 units x $664/unit = $10,624 The remainder of the WAC and SAC fees, along with the Met Council SAC fee shall be paid with the building permit application at the rate in effect at that time. The proposed location of the catch basin on the east side of the cul de sac must be shifted so that it will not conflict with the pedestrian ramp to the trail between Lots 11 and 12, Block 1. Mr. Todd Gerhardt Preserve at Rice Lake — Planning Case 2013-12 July 28, 2014 Page 12 of 21 NOISE WALL The developer proposes to construct a noise wall within MnDOT right of way. MnDOT requires that the City enter into a cooperative agreement in order to allow the wall within the right of way. After completing a wetland delineation as required by MnDOT, the noise wall plans were revised to reflect the wetland conditions and avoid impact. The revised noise wall plans have been submitted to MnDOT for review. To date, the city has not received the revised plans. MnDOT will not release the required noise wall agreement to the city for review and execution until their review is complete and all comments have been implemented. The deadline for MnDOT's review is July 22, 2014. At the time of writing this report, an update on MnDOT's review status and decision was not available. Approval of the noise wall plans and agreement with MnDOT will be on a future City Council agenda. This agreement must be executed before the final plat is recorded. The noise wall will be over the city's 12 -inch trunk water main that extends under Highway 212. The water main within the MnDOT right of way is within a 24 -inch steel casing; therefore, there would not be any impact to the wall should the water main ever need to be replaced.

This fee is broken into water quality and water quantity and is based upon net developable acreage and a multiplier intended to reflect the anticipated burden the land use will place upon the storm sewer system relative to other land uses. Credit is then given for storm water management best management practices at a rate of 50% the water quality rate per acre treated. The table to the left shows the calculations. Buffer areas with proper demarcation, protection and vegetative management are deducted from the calculated area. Not only is the protection and enhancement of open space a necessary component of the PUD process, it serves as a financial reward for proper protection and management. Before permits are issued for any lot adjacent to a wetland, the developer shall install wetland buffer signs at each lot comer and major angle point as shown on sheet Ll Landscape Plan / Planting Plan. A $750.00 security will be required at time of final plat to assure this is completed. Mr. Todd Gerhardt Preserve at Rice Lake — Planning Case 2013-12 July 28, 2014 Page 13 of 21 Before the final plat is recorded the DNR must approve the wetland vegetation management plan. Outlots A and B shall be deeded to the city. EROSION PREVENTION AND SEDIMENT CONTROL within the channel increases. Peak discharge rates are increased at both places where drainage will leave the site. In both instances the outlet channel has become incised and head cuts are forming within the channel. At the outfall downstream of the driveway, a surge basin was installed at some point in the past. The channel has since worked around either side of the surge basin as illustrated in the photograph to the left. The other channel is incised. The depth of this incision will increase and will almost certainly accelerate as the discharge rate and, therefore, the scour force In both instances, these channels discharge to Rice Marsh Lake and the resulting erosion will lead to increased sediment deposition into the lake. The shoreland PUD standards requires that erosion control and storm water management facilities "be designed, and their construction managed, to minimize the likelihood of serious erosion occurring either during or after construction..." Efforts must be taken to reduce the rate of runoff or assure that the channels are stabilized to prevent further degradation. The total disturbed area is approximately 8.5 acres which exceeds the one -acre threshold. Given the total disturbance it must be compliant with the National Pollution Discharge Elimination System General Permit Authorization to Discharge Stormwater Associated with Construction Activity (NPDES Construction Permit). As part of this permit, the applicant is required to develop a Surface Water Pollution Prevention Plan (SWPPP) with three elements: a narrative, plan sheets and standard detail plates. Each of these elements requires specific content. Section 19-145 of Chanhassen City Code requires that the construction is compliant with the NPDES Construction Permit and the SWPPP is provided to the City for review and comment. A draft Surface Water Pollution Prevention Plan (SWPPP) has been prepared and submitted. This plan shall be edited and updated throughout all phases of development including home construction. The primary contractor responsible for day-to-day operations of the site shall be identified and the SWPPP updated to reflect this prior to any disturbance on the site. This updated SWPPP shall be made available to the City at the pre -construction meeting. The following changes need to be incorporated into the SWPPP before any site grading can occur. Mr. Todd Gerhardt Preserve at Rice Lake — Planning Case 2013-12 July 28, 2014 Page 14 of 21 • The sheet labeled Appendix C-1: Erosion and Sediment Control Plan shall show erosion control blanket covering the disturbed areas adjacent to the road crossing the wetland and above the 894' contour for the most southwesterly pond. • All erosion control blanket except in the overland emergency overflow areas shall either be netting -free or use jute netting or another biodegradable material approved by the City. • Topsoil shall be stripped and stockpiled in a berm on the up -gradient side of the silt fence. This shall be indicated on Appendix C-1: Erosion and Sediment Control Plan. • Sheets L-1 and L-2 shall be added to the SWPPP after Appendix C-2 as these are part of the Final Stabilization Plan for the site. An escrow in the amount of $62,815 will be due with the final plat for erosion and sediment control. This amount was calculated based upon the estimated SWPPP quantities provided by the applicant. Clearing and grubbing and common excavation were deducted from this figure. Select granular topsoil was added to this based upon 70% of the lot area to a depth of 6 inches. WETLAND PROTECTION Graham Environmental Services, Inc. (GES) performed an on-site wetland determination and boundary delineation on April 28 and May 4, 2011. This was reviewed by city staff as the local government unit (LGU) responsible for administration of the Wetland Conservation Act and submitted to the technical evaluation panel for comment. Based upon review of the delineation, the boundaries were approved excepting that Wetland C and Wetland D were determined to be part of the same basin and Wetland B was expanded to the north. The current plan submittal appears to accurately reflect these modified boundaries. The plan set was provided by Probe Engineering Company, Inc. on behalf of J&S Ventures. The plan shows the required buffer around wetlands A through D but does not show a buffer around wetland E. All wetlands, including Wetland E, require the establishment of buffer areas and setbacks per Section 20-411 of Chanhassen City Code. Any wetland buffer areas that are disturbed, do not meet the requirement for native vegetation as stated in §20411, or which contains noxious weeds must have a detailed vegetation management plan and that plan must be followed. These areas must be identified as buffer on the plan. SHORELAND MANAGEMENT This property lies within the Shoreland Management District and is subject to the Planned Unit Development (PUD) requirements. The applicant must demonstrate that by granting the flexibility that comes with a PUD, enhancements are made that would not be seen with a straight single-family residential development plan. A detailed management plan, with scheduled maintenance activities, has been prepared as required with the preliminary plat approval conditions. This plan should be adequate to manage these disturbed areas to provide the aesthetic, ecological and water quality benefits for which the Mr. Todd Gerhardt Preserve at Rice Lake — Planning Case 2013-12 July 28, 2014 Page 15 of 21 open space is intended to provide. However, the Department of Natural Resources shall need to make such a determination. PARK DEDICATION Comprehensive Park Plan The city's comprehensive park plan calls for a neighborhood park to be located within one-half mile of every residence in the city. The proposed Preserve at Rice Lake development would not meet this guideline. The nearest park is Rice Marsh Lake Park which is located approximately one mile away if utilizing the city's pedestrian trail network. Comprehensive Trail Plan The city's comprehensive trail plan calls for the future completion of the Rice Marsh Lake Trail to be constructed around the perimeter of the lake. This proposed subdivision should provide for and construct a trail connection to this future trail starting at the public street and extending to the southeast corner of the property. This trail connection should be situated in a public outlot or trail easement. TREE PRESERVATION/LANDSCAPING The applicant has provided a tree inventory and removal plan for the subdivision. Bufferyard plantings are required for this development along Highway 212. Tree preservation calculations for the development are shown below. Total upland area (excluding wetlands) 413,111 SF or 9.48 acres Total canopy area (excluding wetlands) 66,600 SF or 1.52 acres Baseline canopy coverage 16% Minimum canopy coverage allowed 25% or 103,277 SF Proposed tree preservation 4% or 16,820 SF The developer does not meet minimum canopy coverage allowed. Additional plantings will be required to bring the baseline canopy coverage up to the minimum required. Required plantings 87 trees (66600-16820)x1.2 54 trees required (103277-66600) 33 trees required The applicant has proposed a total of 48 new trees and 50 transplanted evergreens in the landscape plan. The applicant is required to provide bufferyards along Highway 212. The minimum plantings required and the applicant's proposed quantities are shown in the table below. Mr. Todd Gerhardt Preserve at Rice Lake - Planning Case 2013-12 July 28, 2014 Page 16 of 21 The applicant does not meet minimum requirements for bufferyard plantings along the south property line. All but a handful of trees are located offsite on MnDOT property. Staff recommends the landscaping be located on the applicant's property unless proof of MnDOT approval is given to the city.

The proposed construction activity as shown in the final construction plans for this project include grading, erosion and sediment control, street construction, water and sanitary sewer, storm sewer, stormwater ponding, turf establishment, and all details necessary to construct this project The total estimated disturbed area is 8.5 acres and the estimated volume of earthwork to be moved on site is 30,000 CY The construction plans address foreseeable conditions and how to best manage the risk associated with the conditions. The Operator will be required to prepare a Site Plan when working around sensitive areas. Individual Site Plans will be incorporated into the SWPPP by amendment. Knowledgeable Person/Chain of Responsibilitv The Owner is responsible for compliance with all terms and conditions of the permit. The Owner will designate a SWPPP trained designer and inspector to oversee the implementation of the SWPPP. The Operator is the Contractor hired by the Owner to construct the project. The Operator will provide a SWPPP trained inspector to implement the installation, inspection and maintenance of the erosion prevention and sediment control BMPs of the SWPPP until construction is complete, the entire site has undergone final stabilization and the NOT has been submitted to the MPCA. This individual will be available to meet the MPCA on site within 72 hours upon request by the MPCA. Project Contacts Owner: SWPPP Designer: SWPPP Inspector: John Knoblauch, 612-490-4540 Curt Kallio, 612-418-6828 Once the identities of the responsible parties are known, the SWPPP will be amended to include this information in Appendix G. SWPPP Training The SWPPP has been prepared by a trained SWPPP designer. The Operator shall designate a SWPPP trained inspector and SWPPP trained installer to implement the SWPPP. Documentation of the training will be in Appendix G of the SWPPP and include the following: a. Names of the SWPPP Preparer, SWPPP Inspector, and SWPPP Installer b. Dates of training and name of instructor and entity providing the training c. Training content that commensurate with the individuals job duties and responsibilities including the number of hours of training Stormwater Design Calculations and Narrative Permanent stormwater management will be achieved by wet detention ponds. Appendix B includes the narrative, stormwater discharges, design requirements and calculations. Appendix B does not contain the actual HydroCAD modeling results, but they are available upon request. Maintenance of Permanent Stormwater Systems The City of Chanhassen will be responsible for the long term operation and maintenance of the Permanent Stormwater Management Systems including the storm sewer system and wet ponds. Preserve on Rice Lake — Chanhassen, MN Stockpiles will be covered or stabilized within (7) days after work has ceased. Final site stabilization of all exposed areas will be completed within (7) days after the construction activity in that portion of the site has temporarily or permanently ceased. SWPPP Components The erosion and sediment control plans which include the location and type of all temporary and permanent erosion prevention and sediment control BMPs along with details for the BMPs are shown in Appendix C. If additional BMPs become necessary during construction, the Owners SWPPP designer will recommend and/or approve such BMPs. Specifications for SWPPP related construction are reference in the individual plan sheets. Special Provisions if required, are found in Appendix G. The most current construction plans are hereby included into the SWPPP by reference and are not attached. The construction plans will be referred to as Appendix F. Estimated Quantities Estimated quantities for erosion and sediment control items are included in Appendix E. Impervious Surface The pre and post construction impervious surfaces are as follows: Pre -Construction = 0.0 acres Post -Construction = 2.50 acres Site Mao A site map with steep slopes, impervious surfaces, soil types, locations of potential pollutant generating activities, areas not to be disturbed, and buffer zones are included in Appendix A. A site map with existing and final grades, including dividing lines and direction of flow for all pre and post construction stormwater runoff drainage areas located within the project limits are included with the Stormwater Management Plan and Calculations in Appendix B. Maps of Surface Waters and Wetlands A map of all surface waters, existing wetlands, and stormwater ponds within one mile from the project boundaries that will receive stormwater from the construction site, during or after construction is shown in Appendix D. Special or impaired waters are idenfified on the map. Final stabilization Final site stabilization methods are shown in Appendix C. Soil Management Existing topsoil will be stripped and preserved. Soil compaction will be avoided in areas not needing to be compacted. All areas to have vegetation re-established will receive 6" of topsoil covering. Chemical treatments No chemical treatments systems are proposed Timing of Installation/Construction Staging Documentation of Infeasibility Construction is anticipated to begin in fall of 2013. Grading construction is anticipated to be completed in 2014. There is no infeasibility of constructing temporary sedimentation basins on this project. There is no infeasibility associated with available right-of-way. The rock construction entrance and inlet protection on Tigua Lane will be constructed before any other construction activity. The Operator will sweep tracked soils on paved surfaces. Environmental Review Stormwater Measures There are no stormwater pollution mitigation measures identified in environmental review, endangered species review, Perimeter controls will be placed before land disturbing activities. Temporary sedimentation basins will be constructed archeological or other required local, state or federal review conducted for the project. immediately after perimeter controls have been placed if required. Areas of grading are clearly marked in the plans by the "construction limits" notation. SWPPP Narrative — Page 1 Stormwater Pollution Prevention Plan (SWPPP) Narrative Karst Areas There are no known karst areas within this site. Impaired Waters and Total Maximum Daily Loads (TMDLsi There are no special or impaired waters located within 1 mile of the project limits that receive runoff from the project site. There are two impaired lakes within 1 mile of the project, but they do not receive runoff from the project site. Those lakes are listed below: Riley Lake: Impairments — Mercury in fish tissue, nutrientleutrophication biological indicators Lake Susan: Impairments — Mercury in fish tissue, nutrient/eutrophication biological indicators Environmentally Sensitive Areas There are existing wetlands surrounding the site that receive runoff from the site. Temporary sedimentation basins should be used to treat concentrated runoff from exposed areas prior to releasing it to the wetlands. Areas upslope of the existing wetlands need to be stabilized within 24 hours of final grading if a temporary sedimentation basin is not used. SWPPP Amendments The SWPPP will be amended as necessary when there is a change in design, construction, operation, maintenance, weather or seasonal conditions that has a significant effect on the discharge of pollutants to surface waters or underground waters. The SWPPP may also be amended when inspections or investigations by site Owner or operators, USEPA or MPCA officials indicate the SWPPP is not effective in eliminating or significantly minimizing the discharge of pollutants to surface waters or underground waters or that the discharges are causing water quality standard exceedances. Soil Types The soil types found on this project are primarily clay loams with a hydrologic soil group of B/C as shown in Appendix A. Due to the slopes on the site and the concentrated flows expected, these soils would be considered susceptible to erosion. These soils will also adhere to equipment and tires when wet so tracking is expected when there are wet conditions. Temporary Sedimentation Basins No designated temporary sedimentation basin locations are shown. The Operator will provided temporary sedimentation basins when mandated by the permit and should use them as a normal part of the grading operations when not required. Dewatering And Basin Draininq Dewatering is anticipated for some street construction and pipe installation. The Operator will provide a SWPPP amendment for proposed dewatering activities. Turbid or sediment laden waters related to dewatering or basin draining will be discharged to a sedimentation basin or storage tank. The discharge from the sedimentation basin or storage tank may be released to surface waters if the water has been visually checked to ensure adequate treatment has been obtained and nuisance conditions will not result from the discharge. If discharge water contains oil or grease, an oil water separator or suitable filtration device will be used prior to discharging the water. Discharge points will be adequately protected from erosion and scour. The discharge will be dispersed over natural rock riprap, sand bags, plastic sheeting, or other accepted energy dissipation measures. All water from dewatering or basin draining activities will be discharged in a manner that does not cause nuisance conditions, erosion in receiving channels or on downslope properties, or inundation in wetlands causing significant adverse impact to the wetland. If filters with backwash water are used, the backwash water will be hauled away for disposal, return the backwash water to the beginning of the treatment process, or incorporate the backwash water into the site in a manner that does not cause erosion. The backwash water may be discharged to the sanitary sewer if permission is granted by the sanitary sewer authority. The filters and/or media should be replaced or cleaned as necessary for adequate function. Preserve on Rice Lake — Chanhassen, MN Inspections and Maintenance The Operators SWPPP trained inspector will routinely inspect the entire construction site at least once every seven (7) days during active construction and within 24 hours after a rainfall event greater than 0.5 inches in 24 hours. Following an inspection that occurs within 24 hours after a rainfall event, the next inspection will be conducted within seven (7) days after the rainfall event. All inspections and maintenance conducted during construction will be recorded within 24 hours in writing and these records will be retained with the SWPPP. Records of each inspection and maintenance activity will include: a. Date and time of inspections b. Name of person(s) conducting inspections c. Findings of inspections, including the specific location where corrective actions are needed d. Corrective actions taken (including dates, times, and party completing maintenance (activities) e. Date and amount of all rainfall events greater than 1/2 inch (0.5 inches) in 24 hours. Rainfall amounts will be obtained by a properly maintained rain gauge installed onsite, a weather station that is within i mile of your location or a weather reporting system that provides site specific rainfall data from radar summaries. f. If any discharge is observed to be occurring during the inspection, a record of all points of the property from which there is a discharge will be made, and the discharge should be described (i.e., color, odor, floating, settled, or suspended solids, foam, oil sheen, and other obvious indicators of pollutants) and photographed. g. Any amendments to the SWPPP proposed as a result of the inspection will be documented as required in Part III.B. within seven (7) calendar days. Inspection Frequency Adjustment a. Where parts of the project site have permanent cover, but work remains on other parts of the site, inspections may be reduced to once per month in those areas of permanent cover. b. Where construction sites have permanent cover on all exposed soil areas and no construction activity is occurring anywhere on the site, the site will be inspected during non -frozen ground conditions at least once per month for a period of twelve (12) months. c. Where work has been suspended due to frozen ground conditions, the inspections may be suspended. The required inspections and maintenance schedule will begin within 24 hours after runoff occurs at the site or 24 hours prior to resuming construction, whichever comes first. Inspections and maintenance of temporary and permanent water quality management BMPs will be performed until another Permittee has obtained coverage under this Permit or the project has undergone Final Stabilization, and an NOT has been submitted to the MPCA. All erosion prevention and sediment control BMPs and Pollution Prevention Management Measures will be inspected to ensure integrity and effectiveness during all routine and post -rainfall event inspections. All nonfunctional BMPs will be repaired, replaced, or supplemented with functional BMPs by the end of the next business day after discovery. The following inspection and maintenance requirements will be complied with: a. All perimeter control devices will be repaired, replaced, or supplemented when they become nonfunctional or the sediment reaches (1/2) of the height of the device. These repairs will be made by the end of the next business day after discovery, or thereafter as soon as field conditions allow access. b. Temporary and permanent sedimentation basins will be drained and the sediment removed when the depth of sediment collected in the basin reaches (1/2) the storage volume. Drainage and removal will be completed within 72 hours of discovery, or as soon as field conditions allow access. c. Surface waters, including drainage ditches and conveyance systems, will be inspected for evidence of erosion and sediment deposition during each inspection. All deltas and sediment deposited in surface waters, including drainage ways, catch basins, and other drainage systems will be removed. Areas of exposed soil at removal locations will be re -stabilized. The removal and stabilization will take place within seven (7) days of discovery unless precluded by legal, regulatory, or physical access constraints. d. Construction site vehicle exit locations will be inspected for evidence of off site sediment tracking onto paved surfaces. Tracked sediment will be removed from all paved surfaces both on and off site within 24 hours of discovery, or if applicable, within a shorter time to comply with the permit. e. Streets and other areas adjacent to the project will be inspected for evidence of off site accumulations of sediment. If sediment is present, it will be removed in a manner and at a frequency sufficient to minimize off site impacts. SWPPP Narrative — Page 2 Stormwater Pollution Prevention Plan (SWPPP) Narrative All infiltration, filtration, and bioretention areas will be inspected to ensure that no sediment from ongoing construction activity is reaching the infiltration area, and that equipment is not being driven across those areas. Building products that have the potential to leach pollutants will be under cover (e.g., plastic sheeting or temporary roofs) to prevent the discharge of pollutants or protected by a similarly effective means designed to minimize contact with stormwater. Pesticides, herbicides, insecticides, fertilizers, treatment chemicals, and landscape materials will be under cover (e.g., plastic sheeting or temporary roofs) to prevent the discharge of pollutants or protected by similarly effective means designed to minimize contact with stormwater. Hazardous materials, toxic waste, (including oil, diesel fuel, gasoline, hydraulic fluids, paint solvents, petroleum based products, wood preservatives, additives, curing compounds, and acids) will be properly stored in sealed containers to prevent spills, leaks or other discharge. Restricted access storage areas will be provided to prevent vandalism. Storage and disposal of hazardous waste or hazardous materials will be in compliance with Minn. R. ch. 7045 including secondary containment as applicable. Solid waste will be stored, collected and disposed of property in compliance with Minn. R. ch. 7035. Portable toilets will be positioned so that they are secure and will not be tipped or knocked over. Sanitary waste will be disposed of properly in accordance with Minn. R. ch. 7041. Fueling and Maintenance of Equipment or Vehicles Spill Prevention and Response: Reasonable steps will be taken to prevent the discharge of spilled or leaked chemicals, including fuel, from any area where chemicals or fuel will be loaded or unloaded including the use of drip pans or absorbents unless infeasible. Fueling will be be done in a contained area unless infeasible. Adequate supplies will be available at all times to clean up discharged materials and that an appropriate disposal method is available for recovered spilled materials. Spills will be reported and cleaned up immediately as required by Minn. Stat. § 115.061, using dry clean up measures where possible. No fuel storage tanks in excess of 1000 gallons will be onsite during construction. All onsite fuel storage tanks shall have secondary protection for spills. Vehicle and Equipment Washing Washing of vehicles is limited to a defined area of the site. Runoff from the washing area will be contained in a sediment basin or other similarly effective controls and waste from the washing activity will be properly disposed of. Soaps, detergents, or solvents will be properly stored. No engine degreasing is allowed on site. Concrete and Other Washouts Waste Effective containment will be used for all liquid and solid wastes generated by washout operations (concrete, stucco, paint, form release oils, curing compounds and other construction materials) related to the construction activity. The liquid and solid washout wastes will not contact the ground, and the containment will be designed so that it does not result in runoff from the washout operations or areas. Liquid and solid wastes will be disposed of properly and in compliance with MPCA rules. A sign will be installed adjacent to each washout facility that requires site personnel to utilize the proper facilities for disposal of washout wastes. All concrete trucks shall have a self-contained collection system for washouts and no concrete trucks will be allowed to washout onto the site. Curb machines or concrete pavers may be washed out on site provided that it is done on the road grade and no washout water leaves the road grade. Final Stabilization All disturbed areas to be re -vegetated shall receive a minimum of 6" of topsoil, be seeded with Mn/DOT Seed Mixture 250 at 70 Ib/acre, and mulched with Type 1 mulch at 2 tons/acre, unless specified otherwise. A lawn seed mixture or sodding (type lawn) may be substituted in proposed lawn areas at the discretion of the Owner. Preserve on Rice Lake — Chanhassen, MN It is anticipated that sufficient topsoil will be obtained from excavations on-site. On-site topsoil shall be considered acceptable for re -use. If topsoil borrow is required, it shall meet the requirements of Mn/DOT 3577. All disturbed areas shall be stabilized within the time frames as specified in the NPDES Permit. The final as -built plan will verify drainage patterns as per the approved grading plan. Within 30 days after final site stabilization, the Owner shall submit a NOT. Final Stabilization is not complete until all of the requirements below are met: 1. All soil disturbing activities at the site have been completed and all soils are stabilized by a uniform perennial vegetative cover with a density of 70 percent of its expected final growth density over the entire pervious surface area, or other equivalent means necessary to prevent soil failure under erosive conditions. 2. The permanent stormwater management system is constructed, meets all requirements in Part III.D. of the permit and is operating as designed. Temporary or permanent sedimentation basins that are to be used as permanent water quality management basins have been cleaned of any accumulated sediment. All sediment has been removed from conveyance systems and ditches are stabilized with permanent cover. 3. All temporary synthetic and structural erosion prevention and sediment control BMPs (such as silt fence) have been removed. BMPs designed to decompose on site (such as some compost logs) may be left in place. 4. For residential construction only, individual lots are considered finally stabilized if the structure(s) are finished and temporary erosion protection and downgradient perimeter control has been completed and the residence has been sold to the homeOwner. Additionally, the Permittee has distributed the MPCA's "Homeowner Fact Sheet" to the homeowner to inform the homeowner of the need for, and benefits of, permanent cover. 5. For construction projects on agricultural land (e.g., pipelines across crop, field pasture or range land) the disturbed land has been returned to its preconstruction agricultural use. Transfer of Ownership If lots are sold and residential home construction is to begin prior to final site stabilization, a Notice of Termination/Permit Modification Form will be used to transfer the permit to the Owner of the lot.
