CHANHASSEN PLANNING COMMISSION REGULAR MEETING JUNE 21, 2016 Chairman Aller called the meeting to order at 7:00 p.m. MEMBERS PRESENT: Andrew Aller, John Tietz, Maryam Yusuf, Nancy Madsen, and Steve Weick MEMBERS ABSENT: Mark Undestad and Mark Randall STAFF PRESENT: Bob Generous, Senior Planner; MacKenzie Walters, Planner; and Alyson Fauske, Assistant City Engineer PUBLIC PRESENT: Dan Kurth 742 Tilia Lane Jeff Kleiner 655 Carver Beach Road Phil Hanson 621 Carver Beach Road Ken Vermeer 730 Preakness Lane PUBLIC HEARING: BANDIMERE PARK: INTERIM USE PERMIT FOR GRADING AT BANDIMERE PARK ON PROPERTY ZONED AGRICULTURAL ESTATE DISTRICT (A-2) LOCATED AT 9405 GREAT PLAINS BOULEVARD. APPLICANT/OWNER: CITY OF CHANHASSEN. Fauske: Thank you Chairman Aller, members of the Planning Commission. It's my pleasure to provide you some background information on the interim use permit request. The applicant is the City of Chanhassen. The interim use permit is to request grading in excess of 1,000 cubic yards. Anything less than 1,000 cubic yards staff is able to do administratively so we're here tonight to hold the public hearing for the proposed improvements. This item is scheduled to go to the City Council on July 11, 2016. The location of the site, it's on the west side of 101. South of Highway 212 and north of Pioneer Trail over near the Lake Riley area. Little bit of background on the subject area. The Bandimere Community Park, there was a referendum in 1998 to acquire the original piece of the park property. Subsequently additional funds were acquired in order to start installing some improvements and most recently these 2 parcels on the northwest side of the park were acquired shifting the access from, it was a location somewhere in here, up to the north at a location where there is better sight distance. As such the parks department along with the parks and recreation committee, in following with their master plan have proposed some improvements to the addition of Bandimere Park in which they need to do some grading. There was a stockpile that was installed in the area during the 101 improvement project so this interim use permit is to remove some of the material that was placed with that Chanhassen Planning Commission — June 21, 2016 • project, and then of course prep the area for the proposed improvements. The proposed improvements on the site, I took the layout and overlaid it on the aerial just to give you a little bit of a frame of reference. It might be off just a little bit but you'll get an idea of where the proposed improvements are proposed. Parking lot with some lighting in this area here. A hockey pavement area at this location with a bituminous trail connecting to the two, and then also to the existing trail system. There's a pipeline easement at this location so there's a little bit of grading proposed within the pipeline easement but that's certainly a site characteristic that dictates what can be done in that area. The pipeline companies don't allow structures within their easement and they certainly, and they're also very cautious about construction that occurs within the easement. The proposed improvements as I mentioned require some grading. The stockpile area that I previously mentioned is in this location so we have about 9 feet of cut from what's currently out in that location with wetland area over here. They have some surface stormwater management features both to the west of the parking lot and to the north of the hockey area. And then they've also included their subgrade preparation for these improvements in their calculations so it's an export of material from the site. They have not yet identified where the material will be going. That will be up to the contractor to determine so we don't have that set at this time. Staff has reviewed it. We have a recommendations for approval within the staff report. It's a fairly straight forward review. Therefore staff has a recommendation to adopt the, or pardon me. To approve the interim use permit for grading in excess of 1,000 cubic yards and with that I would be happy to answer any questions that the commission might have at this time. Aller: Great. Before we go to any questions that anybody might have I'd like to remind those of you at home as well as those in the audience that on our website we have these items and these reports for you to take a look at rather than go through each individual recommendation which there are numerous recommendations here. We'll hit those that are requiring questions to be answered on and those would be discussed but otherwise you can find those on those reports and it's on the website for your perusal and again you can look at those either tonight at this point in time or before this matter goes to City Council for final action. So with that does anybody have any questions based on the report and the presentation? Madsen: I have a question. Aller: Sure. Madsen: There was a mention of a warming house or proposed warming house and I could not locate it on the plans. Just curious where that was going to be located. Fauske: I didn't either. Madsen: Maybe it's not yet determined. 2 Chanhassen Planning Co• ission — June 21, 2016 • Fauske: Oh I believe it's right in this location here. Let's see Sheet C4 is what I'm looking at and that's what I gleaning from Sheet G4. The street plan. It looks like there's a roof structure located just to the southwest. On the southwest side of the hockey arena. I believe that would be an appropriate place for the warming house. Madsen: Okay, thank you. Fauske: You're welcome. Aller: And then just quickly is the grading going to be done all at once or is it going to be phased? Fauske: It will be all done at once. Aller: And then the grading plans, the hydrology isn't fixed at this point in time. They'll be, if this moves forward be required to come forward with new numbers and fulfill those requirements and recommendations. Fauske: Correct and staff does not anticipate any issues with getting those 2 documents in alignment with each other. Aller: Any other questions at this time based on the report? Seeing none I will ask the applicant, well it's us. Fauske: I have no further. Aller: No further information. Fauske: Ways to address the council further. Aller: So we'll move straight to the public hearing and have an opportunity for individuals in the audience to come forward and speak either for or against an item or ask questions so we can get it answered for you. So any individual wishing to come forward can do so at this time. So please come forward. State your name and address for the record. Ken Vermeer: My name is Ken Vermeer and I live in 730 Preakness Lane, Chanhassen, Minnesota. Aller: Welcome. Ken Vermeer: Do we have any idea of how much in excess of 1,000 cubic yards we're going to be grading? 3 Chanhassen Planning Commission — June 21, 2016 • e Aller: If you could answer that, that would be great. Fauske: Certainly Chairman Aller. I'd be happy to. 'They've estimated about 6,000 cubic yards of removals and then additional 2,000 to 3,000 cubic yards for the subgrade correction of the parking lot and the hockey area. We were looking at it today. Those numbers to me seem a little bit high so we've been talking to the engineer to just go over his calculations and make sure we're on the same page as far as how much material we're looking at here. Ken Vermeer: And did you state earlier that the 6,000 cubic yards then that are coming out of there don't have a destination yet? Fauske: At this time they do not. The way the contract documents for this project have been written is that the material becomes the property of the contractor and so the contractor would then identify where they're taking it to. Typically when we have a project such as this we request haul routes to ensure that we have the truck traffic moving through an appropriate area using the appropriate roads and we also ensure that if they are moving, if the material is staying within Chanhassen that the site they're taking it to has the appropriate permits in place in order to place that material there. Ken Vermeer: Very good, thank you. Aller: Thank you. Appreciate the questions. Any other individual wishing to come forward? Ask a question. State your position either for or against. Seeing no one come forward I'll close the public hearing at this point in time and open it for commission discussions. Anybody wish to comment on it at this point? Based on the report or the questions and answers that have been provided. I remember going out to this site a couple years ago on a joint trip with the Environment and Parks and Rec Commission and kind of seeing where it was headed and so I'm glad to see that it's moving forward for municipal purposes in fairly quick fashion. I'm sure the residents there will be happy to have these improvements finalized and the ability to use the park for all these great uses so with that I'll entertain a motion. Yusuf: Okay I'll make the motion. Aller: Commissioner Yusuf. Yusuf. The Chanhassen Planning Commission recommends that the City Council approve the Interim Use Permit to permit grading in excess of 1,000 cubic yards and adopts the Findings of Fact and Recommendations. Aller: I have a motion. Do I have a second? Madsen: Second. 4 Chanhassen Planning Co• ission — June 21, 2016 • Aller: Having a motion and a second, any further discussions? Yusuf moved, Madsen seconded that the Chanhassen Planning Commission recommends that the City Council approve the Interim Use Permit to permit grading in excess of 1,000 cubic yards to include parking lot alterations, storm water improvements and the grading of a hockey rink, plans prepared by Hoisington Koegler Group, Inc. dated May 29, 2016 and subject to the following conditions and adoption of the Findings of Fact and Recommendations: The grading plan, hydrologic map and storm water model shall be revised to be consistent with each other. 2. The plan must obtain appropriate permits from the Riley Purgatory Bluff Creek Watershed District. 3. The plan set must be revised to show the correct proposed slope from the parking lot to the north wetland. 4. A buffer must be established and maintained around the wetland and monuments must be installed. The plan shall be revised to show the first floor elevation of the proposed warming house. 6. Emergency Overflow locations and elevations shall be shown on the grading plan. 7. Autumn Blaze maples shall not be included in the planting plan. An alternate species, approved by the City, shall be provided. 8. Signed, professional design and building permit required for any retaining walls exceeding 48 inches in height. All voted in favor and the motion carried unanimously with a vote of 5 to 0. Aller: This matter again will be before the City Council on July 11, 2016. Moving onto item 2 on tonight's calendar.

APPLICANT: CASTLE GATE CONSTRUCTION. OWNER: TRAVIS SENEFELDER. 1(-°-/(i Chanhassen City Council 11, 2016 • Mayor Laufenburger: Any other visitors that would like to speak at this time? Very well, let's move on to our next item. BANDIMERE PARK: REQUEST FOR INTERIM USE PERMIT FOR GRADING ON PROPERTY ZONED AGRICULTURAL ESTATE DISTRICT (A21 LOCATED AT 9405 GREAT PLAINS BOULEVARD. APPLICANT/OWNER: CITY OF CHANHASSEN. Mayor Laufenburger: Is that you Mr. Oehme? Paul Oehme: It is. Mayor Laufenburger: Alright, welcome. Good evening Mr. Oehme. Paul Oehme: Good evening Mayor, City Council members. This is an interim use permit application request for Bandimere Park improvements for 2016. As you know Bandimere Park is located just south of Lyman Boulevard here and off of 101. One of our main parks for the community. The improvements that are being proposed include the parking lot which is 23 stalls right here. There's a hockey rink with lights and a paved hockey rink and permanent boarding around it. There's also exterior hockey rink as well. There's trail included. Parking and street lights in the parking lot and stormwater improvements to take care of this stormwater associated with the new runoff. The reason for the interim use permit application is excavation amount. The material that's going to be hauled off. Trucked off site is in excess of 1,000 cubic yards so that's the reason for the improvements. The improvements are I think are planned for 2016 so the parks department is going to be soliciting bids to make those improvements this year yet so with that brief background on the project itself. Todd Hoffman the Park Director is here to answer any questions you may have about the specific project but staff is recommending that the interim use permit be approved for this project. I would stand for questions. Mayor Laufenburger: Alright, any questions for Mr. Oehme? Councilwoman Ryan. Councilwoman Ryan: Actually for Mr. Hoffman about the project itself. Two questions. Will the park still be open while some of the work is going on? Todd Hoffman: It will be. Councilwoman Ryan: It will. Todd Hoffman: The project site is nicely isolated and the entry for construction is near the front of the park so the park will remain open and operational during construction. Councilwoman Ryan: And was there a decision, is it going to be temporary warming house? There won't be a permanent structure. Chanhassen City Council —July 11, 2016 • Todd Hoffman: There will not be a permanent structure there. Currently it will be brought on site for the 2 month time period and then moved away. Councilwoman Ryan: Okay, thank you. That's it Mayor. Mayor Laufenburger: Alright. Any other questions? Any comment or motion? Councilwoman Ryan: I'll make a motion. Mayor Laufenburger: Councilwoman Ryan. Councilwoman Ryan: I make a motion that the City Council approves the interim use permit to permit grading in excess of 1,000 cubic yards and adopts the Findings of Fact. Mayor Laufenburger: Is there a second? Councilman Campion: Second. Mayor Laufenburger: Thank you Mr. Campion. Any further discussion? Councilwoman Ryan moved, Councilman Campion seconded that the City Council approves the interim use permit to permit grading in excess of 1,000 cubic yards to include parking lot alterations, stormwater improvements and the grading of a hockey rink, plans prepared by Hoisington Koegler Group, Inc. dated May 20, 2016 subject to the following conditions and adopts the Findings of Fact: I .

ARBOR GLEN: REOUEST FOR REZONING FROM AGRICULTURAL ESTATE DISTRICT (A-2) TO PLANNED UNIT DEVELOPMENT -RESIDENTIAL (PUD -R): CONDITIONAL USE PERMIT FOR DEVELOPMENT WITHIN THE BLUFF CREEK CORRIDOR• AND SUBDIVISION WITH VARIANCES CREATING 21 LOTS AND 4 OUTLOTS APPLICANT• ARBOR GLEN OF CHANHASSEN, LLC. OWNER_: GIANETTI PROPERTIES, LLC. Mayor Laufenburger: Do we have a staff report Ms. Aanenson? Kate Aanenson: Yes, thank you Mayor members of the City Council. This application has a couple of, it's numerous applications in one case. The conditional use permit, a PUD rezoning and a preliminary plat with variance. This item went to the Planning Commission actually last year in September and since that time the applicant has continued to extend the approval process while working through some design issues, most specifically regarding the watershed district so it looks like we're on course now to work through that and I think the good news on this project is it's just north of the Fox Glen so it's nice to tie those two projects. Fox, not Fox Glen. Mayor Laufenburger: Woods. Kate Aanenson: Thank you. Fox Woods. So it'd tie those projects kind of closer together when we talk about trails but I'll go through that in a minute. So the subject site is located on the comer, the southwest comer of Lyman Boulevard and 101. The thing I want to talk most about this project, it's a challenging piece of property and I'll go through a couple more slides explaining that but there's a 34 foot change in elevation. There's a big wetland to the south. In 2008 this is just a portion of the study area that we did in that neighborhood because the park and ride was going in and we had the old, what we called the business fringe which allowed high density and some multi -family so this is when Kwik Trip went in so the neighbors down there were concerned about all the changes happening with 212 going in so we hired a consultant and we worked and came together with a plan and looking at this site, which was guided for low density single family. Looking at that now was that the highest and best use? So a twin home project was approved. After that somebody bought it speculating on getting commercial zoning. That project never was applied for but someone did come in with an application for commercial uses on there. Some Walgreen's and that kind of thing. The challenges here is that it's got the one access point in and there's a barrier here so with the change in grade so there really is one way in and one way out so in looking at this study area the recommendation that came back was • CITY OF CHANHASSEN CARVER AND HENNEPIN COUNTIES, MINNESOTA INTERIM USE PERMIT #2016-16 1.

CHANHAS§JNMAXNWG COMMISSION BY: Its Chairman /(o- / (,-7 CHANHASSEN PLANNING COMMISSION REGULAR MEETING NNE 21, 2016 Chairman Aller called the meeting to order at 7:00 p.m. MEMBERS PRESENT: Andrew Aller, John Tietz, Maryam Yusuf, Nancy Madsen, and Steve Weick MEMBERS ABSENT: Mark Undestad and Mark Randall STAFF PRESENT: Bob Generous, Senior Planner; MacKenzie Walters, Planner; and Alyson Fauske, Assistant City Engineer PUBLIC PRESENT: Dan Kurth 742 Tilia Lane Jeff Kleiner 655 Carver Beach Road Phil Hanson 621 Carver Beach Road Ken Vermeer 730 Preakness Lane PUBLIC HEARING: BANDIME_RE PARK: INTERIM USE PERMIT FOR GRADING AT BANDIMERE PARK ON PROPERTY ZONED AGRICULTURAL ESTATE DISTRICT (A-2) LOCATED AT 9405 GREAT PLAINS BOULEVARD. APPLICANT/OWNER: CITY OF CHANHASSEN. Fauske: Thank you Chairman Aller, members of the Planning Commission. It's my pleasure to provide you some background information on the interim use permit request. The applicant is the City of Chanhassen. The interim use permit is to request grading in excess of 1,000 cubic yards. Anything less than 1,000 cubic yards staff is able to do administratively so we're here tonight to hold the public hearing for the proposed improvements. This item is scheduled to go to the City Council on July 11, 2016. The location of the site, it's on the west side of 101. South of Highway 212 and north of Pioneer Trail over near the Lake Riley area. Little bit of background on the subject area. The Bandimere Community Park, there was a referendum in 1998 to acquire the original piece of the park property. Subsequently additional funds were acquired in order to start installing some improvements and most recently these 2 parcels on the northwest side of the park were acquired shifting the access from, it was a location somewhere in here, up to the north at a location where there is better sight distance. As such the parks department along with the parks and recreation committee, in following with their master plan have proposed some improvements to the addition of Bandimere Park in which they need to do some grading. There was a stockpile that was installed in the area during the 101 improvement project so this interim use permit is to remove some of the material that was placed with that Chanhassen Planning Commission — June 21, 2016 project, and then of course prep the area for the proposed improvements. The proposed improvements on the site, I took the layout and overlaid it on the aerial just to give you a little bit of a frame of reference. It might be off just a little bit but you'll get an idea of where the proposed improvements are proposed. Parking lot with some lighting in this area here. A hockey pavement area at this location with a bituminous trail connecting to the two, and then also to the existing trail system. There's a pipeline easement at this location so there's a little bit of grading proposed within the pipeline easement but that's certainly a site characteristic that dictates what can be done in that area. The pipeline companies don't allow structures within their easement and they certainly, and they're also very cautious about construction that occurs within the easement. The proposed improvements as I mentioned require some grading. The stockpile area that I previously mentioned is in this location so we have about 9 feet of cut from what's currently out in that location with wetland area over here. They have some surface stormwater management features both to the west of the parking lot and to the north of the hockey area. And then they've also included their subgrade preparation for these improvements in their calculations so it's an export of material from the site. They have not yet identified where the material will be going. That will be up to the contractor to determine so we don't have that set at this time. Staff has reviewed it. We have a recommendations for approval within the staff report. It's a fairly straight forward review. Therefore staff has a recommendation to adopt the, or pardon me. To approve the interim use permit for grading in excess of 1,000 cubic yards and with that I would be happy to answer any questions that the commission might have at this time. Aller: Great. Before we go to any questions that anybody might have I'd like to remind those of you at home as well as those in the audience that on our website we have these items and these reports for you to take a look at rather than go through each individual recommendation which there are numerous recommendations here. We'll hit those that are requiring questions to be answered on and those would be discussed but otherwise you can find those on those reports and it's on the website for your perusal and again you can look at those either tonight at this point in time or before this matter goes to City Council for final action. So with that does anybody have any questions based on the report and the presentation? Madsen: I have a question. Aller: Sure. Madsen: There was a mention of a warming house or proposed warming house and I could not locate it on the plans. Just curious where that was going to be located. Fauske: I didn't either. Madsen: Maybe it's not yet determined. 2 Chanhassen Planning Commission — June 21, 2016 Fauske: Oh I believe it's right in this location here. Let's see Sheet C-4 is what I'm looking at and that's what I gleaning from Sheet C-4. The street plan. It looks like there's a roof structure located just to the southwest. On the southwest side of the hockey arena. I believe that would be an appropriate place for the warning house. Madsen: Okay, thank you. Fauske: You're welcome. Aller: And then just quickly is the grading going to be done all at once or is it going to be phased? Fauske: It will be all done at once. Aller: And then the grading plans, the hydrology isn't fixed at this point in time. They'll be, if this moves forward be required to come forward with new numbers and fulfill those requirements and recommendations. Fauske: Correct and staff does not anticipate any issues with getting those 2 documents in alignment with each other. Aller: Any other questions at this time based on the report? Seeing none I will ask the applicant, well it's us. Fauske: I have no further. Aller: No further information. Fauske: Ways to address the council further. Aller: So we'll move straight to the public hearing and have an opportunity for individuals in the audience to come forward and speak either for or against an item or ask questions so we can get it answered for you. So any individual wishing to come forward can do so at this time. So please come forward. State your name and address for the record. Ken Vermeer: My name is Ken Vermeer and I live in 730 Preakness Lane, Chanhassen, Minnesota. Aller: Welcome. Ken Vermeer: Do we have any idea of how much in excess of 1,000 cubic yards we're going to be grading? Chanhassen Planning Commission — June 21, 2016 Aller: If you could answer that, that would be great. Fauske: Certainly Chairman Aller. I'd be happy to. They've estimated about 6,000 cubic yards of removals and then additional 2,000 to 3,000 cubic yards for the subgrade correction of the parking lot and the hockey area. We were looking at it today. Those numbers to me seem a little bit high so we've been talking to the engineer to just go over his calculations and make sure we're on the same page as far as how much material we're looking at here. Ken Vermeer: And did you state earlier that the 6,000 cubic yards then that are coming out of there don't have a destination yet? Fauske: At this time they do not. The way the contract documents for this project have been written is that the material becomes the property of the contractor and so the contractor would then identify where they're taking it to. Typically when we have a project such as this we request haul routes to ensure that we have the truck traffic moving through an appropriate area using the appropriate roads and we also ensure that if they are moving, if the material is staying within Chanhassen that the site they're taking it to has the appropriate permits in place in order to place that material there. Ken Vermeer: Very good, thank you. Aller: Thank you. Appreciate the questions. Any other individual wishing to come forward? Ask a question. State your position either for or against. Seeing no one come forward I'll close the public hearing at this point in time and open it for commission discussions. Anybody wish to comment on it at this point? Based on the report or the questions and answers that have been provided. I remember going out to this site a couple years ago on a joint trip with the Environment and Parks and Rec Commission and kind of seeing where it was headed and so I'm glad to see that it's moving forward for municipal purposes in fairly quick fashion. I'm sure the residents there will be happy to have these improvements finalized and the ability to use the park for all these great uses so with that I'll entertain a motion. Yusuf. Okay I'll make the motion. Aller: Commissioner Yusuf. Yusuf: The Chanhassen Planning Commission recommends that the City Council approve the Interim Use Permit to permit grading in excess of 1,000 cubic yards and adopts the Findings of Fact and Recommendations. Aller: I have a motion. Do I have a second? Madsen: Second. Chanhassen Planning Commission — June 21, 2016 Aller: Having a motion and a second, any further discussions? Yusuf moved, Madsen seconded that the Chanhassen Planning Commission recommends that the City Council approve the Interim Use Permit to permit grading in excess of 1,000 cubic yards to include parking lot alterations, storm water improvements and the grading of a hockey rink, plans prepared by Hoisington Koegler Group, Inc. dated May 29, 2016 and subject to the following conditions and adoption of the Findings of Fact and Recommendations: The grading plan, hydrologic map and storm water model shall be revised to be consistent with each other. 2. The plan must obtain appropriate permits from the Riley Purgatory Bluff Creek Watershed District. The plan set must be revised to show the correct proposed slope from the parking lot to the north wetland. 4. A buffer must be established and maintained around the wetland and monuments must be installed. 5. The plan shall be revised to show the first floor elevation of the proposed warming house. 6.

Planning Commission Bandimere Park Interim Use Permit — Planning Case 2016-16 June 21, 2016 Page 2 of 4 APPLICABLE REGULATIONS Chapter 7, Article II, Excavating, Mining, Filling and Grading Chapter 19, Article VII, Surface Water Management Chapter 20, Article IV, Division 5, Interim Use Permits Chapter 20, Article X, "A-2" Agricultural Estate District BACKGROUND Bandimere Park is a community park. The original 32 acres of property for Bandimere Community Park were acquired in 1988 after a park improvement referendum in which two of four questions passed. Nine years later, another park referendum was approved authorizing the initial construction of the park. Most recently, another 4.5 acres of land has been added to the park along with a new main park entrance being constructed. DISCUSSION The applicant is requesting an interim use permit to grade more than 1,000 cubic yards for site improvements. The proposed project includes parking lot alterations, storm water improvements and the grading of a hockey rink site.

A small southwest portion of the site drains toward a wetland south and west of the proposed grading area. The proposed grading plan would largely maintain the existing drainage patterns. Two treatment basins are proposed, one within the new parking lot island and one north of the ice rink. The plan does not show all new impervious directed toward the treatment basins, but attempts to collect untreated runoff from existing impervious to treat the required amount of runoff. The grading plan, hydrologic map and storm water model shall be revised to be consistent with each other. The plan must obtain appropriate permits from the Riley Purgatory Bluff Creek Watershed District. The slopes of the stormwater pipe outlets into the wetland will likely require modification to accomplish rate control per the Watershed District's permitting process. Per conversations between staff the engineer for this application, the proposed slope from the parking lot to the wetland will not be as steep as shown in the plan set. The plan set must be revised to show the correct proposed slope. A buffer must be established and maintained around the wetland and monuments must be installed The plan shall be revised to show the first floor elevation of the proposed warming house. Emergency Overflow locations and elevations shall be shown on the grading plan. UTILITIES The plan shall be revised to show the locations of draintile cleanouts. LANDSCAPING Minimum landscaping requirements for the parking lot expansion at Bandimere Park include installing a landscape peninsula and 2 overstory trees. One peninsula has been provided as well as 6 overstory trees.

John M. Molinaro Minn. Reg. No. 45831 Date: Bandimere Park — City of Chanhassen PE Project #: 116037 Page 1 Date: 5/12/16 1. Introduction The following is a hydrology summary for the construction of a paved outdoor ice skating rink with warming house and a parking area at Bandimere park. The site is located 1,000 ft south of Lyman Blvd. along Great Planes Blvd. in Chanhassen, Minnesota. ll. Existing Site Conditions A. Current Land Use The site is currently a filled area creating a flat surface for park improvements. The previous land use was a single family home, which has been removed. The site consists of 1.9 acres that will be altered in the project. B. Topography - Existing Hydrology The site has been filled from previously existing conditions, where the slope from the north wetland is roughly at a 4:1 up to a flat area on top. The site was not filled over the existing pipeline. The current drainage is all directed to the north wetland. The soils that were used to create the flat area consist of topsoil and alluvial clays. The Surface Waters & Wetland Areas that receive stormwater within one mile are shown in the Drainage Maps in APPENDIX A. C. Special or Impaired Waters A special and impaired waters search was completed using the MPCA search engine ( http://pca- gis02.pca.state.mn.us/CSW/index.htmI ) on March 23, 2016. The project has a discharge point within one mile of, and flows to, a special water listed in Appendix A, Part B of the NPDES Construction Site General Permit. The project does have a discharge point within one mile of, and flows to, a water listed as impaired under Section 303(D) of the Federal Clean Water Act. Waterbody ID Name of Waterbody Type Special Water Impaired Water Pollutants Approved TMDL Site Discharges to D. Soils 07020012-710 Bluff Creek Impaired Stream No Yes Fish Bioassessments Turbidity No Haugo Geotechnical Services completed an exploration report in January 2016. Five soil borings were completed for this project, each extending to a nominal depth up to 15 feet below the ground surface. The borings found topsoil, clayey fill and buried top to depths Y: foot to 16 feet of fill generally over native clay till soils. The existing fill soils and topsoil are judged to be potentially compressible and generally unsuitable for pavement support. The underlying alluvial and clay till soils appear generally suitable for pavement support. Bandimere Park — City of Chanhassen PE Project #: 116037 Page 2 Date: 5/12/16 A review of the USDA Natural Resources Conservation Services Soils Survey Map (See Appendix H) indicated the following soils on site: Soil Symbol and Soil Name % of Hydrologic T Representative value Erosion Site Soil Group Kf factor Potential % Sand % Silt L -Glencoe clay loam, 0 Slight to 1 percent slopes Glencoe 80 C/D .28 5 22.0 45.0 33.0 KB2-Lester-Kilkenny loams, 2 to 6 percent Slight slopes, eroded B 23.5 Lester, eroded 60 .24 5 39.2 37.3 Kilkenny, eroded 40 C/D .24 5 38.0 36.0 26.0 KC2-Lester-Kilkenny loams, 6 to 12 percent Slight slopes, eroded Lester, eroded 60 B .24 5 39.2 37.3 23.5 26.0 Kilkenny, eroded 40 C .24 5 38.0 36.0 NC3-Lester-Kilkenny clay loams, 6 to 12 percent Slight slopes, severely eroded Lester, severely 60 B 24 4 34.0 37.0 29.0 eroded 28.5 Kilkenny, severely 40 C .24 4 34.2 37.3 eroded TB-Terril loam, 2 to 6 Slight percent slopes Terril 80 B .28 5 46.0 33.0 21.0 Hydrologic soil groups are based on estimates of runoff potential. Soils are assigned to one of four groups according to the rate of water infiltration when the soils are not protected by vegetation, are thoroughly wet, and receive precipitation from long -duration storms. The soils in the United States are assigned to four groups (A, B, C, and D) and three dual classes (A/D, B/D, and C/D). The groups are defined as follows: Group A. Soils having a high infiltration rate (low runoff potential) when thoroughly wet. These consist Bandimere Park - City of Chanhassen PE Project* 116037 Page 3 Date: 5/12/16 mainly of deep, well drained to excessively drained sands or gravelly sands. These soils have a high rate of water transmission. Group B. Soils having a moderate infiltration rate when thoroughly wet. These consist chiefly of moderately deep or deep, moderately well drained or well drained soils that have moderately fine texture to moderately coarse texture. These soils have a moderate rate of water transmission. Group C. Soils having a slow infiltration rate when thoroughly wet. These consist chiefly of soils having a layer that impedes the downward movement of water or soils of moderately fine texture or fine texture. These soils have a slow rate of water transmission. Group D. Soils having a very slow infiltration rate (high runoff potential) when thoroughly wet. These consist chiefly of clays that have a high shrink -swell potential, soils that have a high water table, soils that have a claypan or clay layer at or near the surface, and soils that are shallow over nearly impervious material. These soils have a very slow rate of water transmission. If a soil is assigned to a dual hydrologic group (A/D, B/D, or C/D), the first letter is for drained areas and the second is for undrained areas. Only the soils that in their natural condition are in group D are assigned to dual classes. III. Proposed Site Conditions & Design Considerations A. Proposed Development The proposed development consists of an outdoor ice skating rink with warning house and a parking area. The parking area is located on the western portion of the improved site while the ice rink is located on the eastern porion. Each side of the development will have a storm water treatment basin to provide the storm water management requirements of Riley Purgatory Bluff Creek Watershed District. The design constraints of the north entrance of the parking area was not easily captured by the layout/location of the treatment basin. To capture the correct impervious surface area, a curb cut was made allowing existing street runoff to enter the west basin. The curb cut was placed so that the area of existing street surface entering the basin equaled the amount of proposed parking surface that was not captured. The table below provides information on the estimated acreage of land cover before and after project development.

Proposed Topography The proposed drainage patterns will be reflective of the existing drainage pattens when possible. The drainage maps are shown in Appendix A. C. Design Requirements The Riley Purgatory Bluff Creek Watershed District requires all improvements to meet their Rule J — Stormwater Management requirements. They are listed as follows: 1. Rate Control Riley Pur¢atory Bluff Creek Watershed District Limit peak runoff flow rates to that from existing conditions, at all point leaving the site, for the: 2 year: 10 year: 100 year: 100 year: 10 -day snowmelt: 2. Water Quality Riley Purgatory Bluff Creek Watershed District Provide for at least sixty percent (60 percent) annual removal efficiency for total phosphorous, and at least ninety percent (90 percent) annual removal efficiency for total suspended solids from site runoff. To meet the NPDES Construction Stormwater Permit the permanent sedimentation basins must • The basin must have a permanent volume of 1800 cubic feet of storage below the outlet pipe for each acre that drains to the basin. • The basin must be designed to provide live storage for a water quality volume (calculated as an instantaneous volume) of one (1) inch of runoff from the new impervious surfaces created by the project. • Basin outlets shall be designed such that the water quality volume is discharged at no more than 5.66 cubic feet per second (cfs) per acre of surface area of the pond. The basin's water quality volume is calculated as 1 inch of runoff from the new impervious surfaces created by the project. 3. Volume Control Riley Purgatory Bluff Creek Watershed District Provide for the abstraction onsite of 1.1 inches of runoff from impervious surface of the parcel; i. Where infiltration or filtration facilities, practices or systems are proposed, pretreatment of runoff must be provided. ii. The bottom of infiltration facilities must be at least three feet above seasonal high water table. To meet the NPDES Construction Stormwater Permit the infiltration systems must: • Be design so that the water quality volume of one (1) inch of runoff from the new impervious surfaces created by the project is retained on site (i.e. infiltration or other volume reduction practices) and not discharged to a Surface Water. Bandimere Park — City of Chanhassen PE Project #: 116037 Page 5 Date: 5/12/16 • Discharge the water quality volume routed to the system through the soil surface or filter media within 48 hours or less. • Verify soil type and to ensure a minimum of three (3) feet of separation from the seasonally saturated soils (or from bedrock) and the bottom of the proposed infiltration/filtration system. D. Proposed Hydrology Two filtration/stormwater basins are proposed to treat the runoff for the improvements. Basin WP treats the parking area before discharging to the north wetland complex, Basin EP treats the ice skating area before discharging to the north wetland complex.

A brief summary of our results and recommendations is presented below. Additional details regarding our procedures, results and recommendations follow in the attached geotechnical exploration report. Five soil borings were completed for this project, each extending to a nominal depth up to 15 feet below the ground surface. The borings found topsoil, clayey fill and buried top to depths '/s foot to 16 feet of fill generally over native clay till soils. Portions of the fill soils were dark brown to black in color and had variable penetration resistance values (N -Values). Both the existing fill soils and topsoil are judged to be potentially compressible. Groundwater was encountered in SB -4 at a depth of 11 1h feet while drilling and not encountered after drilling to the cave in depth of 11 feet. Groundwater was not encountered in the remaining four soil borings while drilling or after drilling. The existing fill soils and topsoil are judged to be potentially compressible and generally unsuitable for pavement support. The underlying alluvial and clay till soils appear generally suitable for pavement support. We anticipate soil corrections consisting of removing the existing fill and topsoil and placing engineered fill to establish pavement grades. SB4 performed at the east car parking lot entrance encountered existing fill soils which extended deeper than 16 feet and a portion of the car parking lot will likely be supported by existing fill soils.

Associated with the improvements is the construction of underground utilities and stone water ponds. Pioneer Engineering requested a geotechnical exploration to evaluate the suitability of site soil conditions to support the proposed pavements and to provide recommendations for site development. 1.2 Purpose The purpose of this geotechnical exploration was to characterize subsurface soil and groundwater conditions and provide recommendations for site development. 1.3 Site Description The site is situated east of the access road off Great Plains Boulevard to Bandimere Park, west of a large grass field and north of a car parking lot Based on a review of historical aerial photographs, a building once existing on the area that is proposed to be the park area, The existing structures were recently removed from the southeast comer of the site, prior to our site work. A gas line ems southeast to northwest across the center of the site. The property is generally open, grass covered and relatively flat. The ground surface elevation at our soil boring locations ranged from about 912 to 914 feet mean sea level. 1.4 Scope of Services Our services were authorized by Pioneer Engineer and performed in accordance with HGTS Proposal #15-0878, dated December 7, 2015 and under the terms of our General Conditions. Our scope of services was limited to the following tasks: • Completing five (5) standard penetration test soil borings, each to a nominal depth of 10 to 15 feet. • GPS soil boring locations and elevations. • Visually/manually classify samples recovered from the soil borings. • Performing laboratory testing on select soil samples. • Preparing soil boring logs describing the materials encountered and the results of groundwater level measurements. • Preparing an engineering report describing soil and groundwater conditions, and providing recommendations for site development. 1.5 Documents Provided We were provided with a concept plan of the court and parking lot improvements prepared by the City of Chanhassen, labeled review and dated May 13, 2015. The concept plan indicates a 80 feet by 176 feet concrete pavement hockey/pickleball court, 65 feet by 90 feet grass skate area, 28 car stall bituminous pavement parking lot with two entrances, segments of bituminous trails and a bituminous shelter pad. Grading or utility plans were not available at this time. 1.6 Locations and Elevations The boring locations were selected by jointly by Haugo GeoTechnical Services (HGTS) and Pioneer Engineering. The approximate location of the soil borings are shown on Figure 1, "Soil Boring Location Sketch", in the Appendix. The sketch was prepared by HGT'S using an aerial photograph from the Hennepin County GLS website as a base. Ground surface elevations at the boring locations were obtained by HG`S using GPS measuring equipment. Elevations were based on MN County Coordinates System mean sea level using the GEOID09 (Conus) model. GPS coordinates at the boring locations are provided in Figure 2 in the Appendix. 2.0 FIELD PROCEDURES Five (5) standard penetration test borings were performed on December 22, 2015 by HG`S with a rotary drilling rig, using continuous flight augers to advance the boreholes. Representative samples were obtained from the borings, using the split -barrel sampling procedures in general accordance with ASTM Specification D-1586. In the split -barrel sampling procedure, a 2 -inch O.D. split -barrel spoon is driven into the ground with a 140 - pound hammer falling 30 inches. The number of blows required to drive the sampling spoon the last 12 inches of an 18 -inch penetration is recorded as the standard penetration resistance value, or "N" value. The results of the standard penetration tests are indicated on the boring log. The samples were sealed in containers and provided to HGTS for testing and soil classification. A field log of each boring was prepared by the HGTS drill crew. The logs contain visual classifications of the soil materials encountered during drilling, as well as the driller's interpretation of the subsurface conditions between samples and water observation notes. The final boring logs included with this report represent an interpretation of the field logs and include modifications based on visual/manual method observation of the samples. The soil boring logs, general terminology for soil description and identification, and classification of soils for engineering purposes are also included in the appendix. The soil boring logs identify and describe the materials encountered, the relative density or consistency based on the Standard Penetration resistance (N -value, "blows per foot") and groundwater observations. 2 The strata changes were inferred from the changes in the samples and auger cuttings. The depths shown as changes between strata are only approximate. The changes are likely transitions, variations can occur beyond the location of the boring. 3.0 RESULTS 3.1 Soil Conditions Soil borings 1 and 5 encountered approximately 7 and soil boring 4 encountered greater than 16 feet of previously placed fill soils. The fill soils consist mainly of dark brown, grey and/or black sandy lean clay, clayey sand and/or silty sand. Penetration resistance values (N -Values), shown as blows per foot (bpf) on the boring log, within the existing fill soils were variable and ranged from 4 to 10 bpf. Underlying the fill soils at soil boring 5 or at the surface of soil borings 2 and 3, approximately 1 to 4 feet of clayey topsoil was encountered. The topsoil was dark brown to black in color and judged to be slightly organic. Underlying the existing fill soils and/or topsoil, soil borings 1 thru 3 and 5 generally encountered native alluvial lean clay and/or sandy lean clay glacial till soils extending to the termination depths of the soil borings. The N -values indicate the clays to be generally medium to stiff. 3.2 Groundwater Groundwater was encountered in soil boring SB -4 at a depth of it 1/2 feet (corresponding to an elevation of about 902) while drilling and not encountered after drilling to the cave in depth of 11 feet. At the other four soil borings groundwater was not encountered while drilling or after drilling to the cave in depths of 8 to 13 feet. The approximate water level of Lake Riley to the east of the site is about 875 feet, The groundwater encountered at boring SB -4 appears to be perched groundwater. However, the borings were completed in clayey soils and it may take several hours or days for groundwater to reach its hydrostatic level in an open borehole. Groundwater monitoring wells or piezometers in conjunction with deeper soil borings would be required to more accurately determine water levels. Seasonal and annual fluctuations in the groundwater levels should be expected. 3.3 Laboratory Testing Laboratory moisture content tests were performed on selected samples recovered from the soil borings. Table 1 below summarizes the results of the laboratory tests. Results of the laboratory moisture content tests are also shown on the boring logs adjacent to the sample tested. 3 Table 1. Summary of Laboratory Tests Boring Number Sample Number Depth (feet) Moisture Content (%)* SB -1 S•25 71h 22 SB -2 S-17 5 23% SB -3 S-3 5 201/2 SB -4 S-9 21h 17 SB -5 S-31 5 21 'Moisture contents tests were rounded to the nearest 1h percent 3.4 OSHA Soil Classification The existing fill soils and glacial till soils encountered in the borings generally correspond to the ASTM Classifications CL. The soils identified in the borings will generally be Type B soils under Department of Labor Occupational Safety and Health Administration (OSHA) guidelines. 4.0 DISCUSSION AND RECOMMENDATIONS 4.1 Proposed Construction The City of Chanhassen is proposing to construct a concrete pavement hockey/pickleball court, bituminous pavement 28 car stall parking lot and bituminous trails at Bandimere Park in Chanhassen, Minnesota. Associated with the improvements is the construction of underground utilities and storm water ponds. Grading or utility plans were not available at this time. We have attempted to describe our understanding of the project. If the design or location of the proposed pavements change, we should be informed. Additional analyses and revised recommendations may be necessary. 4.2 Discussion Soil borings 1, 2 and 5 were performed in the proposed concrete pavement court area and encountered about 11/2 to 9 feet of fill and/or topsoil over alluvial clays and/or clay till soils. Soil borings 3 and 4 performed in the proposed bituminous pavement parking lot encountered about 4 feet of topsoil over alluvial/clay till soils at soil boring 3 and greater than 16 feet of fill soils at soil boring 4. Portions of the fill soils were dark brown to black in color and had variable penetration resistance values (N -Values). The existing fill soils and topsoil are judged to be potentially compressible and generally unsuitable for pavement support. The underlying alluvial and clay till soils appear generally suitable for pavement support We anticipate soil corrections consisting of removing the existing fill and topsoil and placing engineered fill to establish pavement grades. Soil boring 4 performed at the east car parking lot entrance encountered existing fill soils which extended to a depth of 16 feet and a portion of the car parking lot will likely be 4 supported by the existing fill soils. There is a risk of pavement settlement due to consolidation of the existing fill soils in this area. Groundwater was encountered in soil boring 4 at a depth of 11 Ih feet while drilling and not encountered after drilling to the cave in depth of 11 feet. At the other four soil borings groundwater was not encountered while drilling or after drilling to cave in depths of 8 to 13 feet. If pockets of groundwater are encountered we anticipate the volume to be small and able to be removed with sumps or pumps. 4.3 Paved Court & Parking Lot Preparation Excavations A structure formerly existed in the southeast corner of the property. We recommend all remnants of the former structure including footings, floor slabs, foundation walls and underground utilities, if encountered, be removed from within the proposed pavement and oversize areas. Likewise we recommend that all vegetation, existing fill soils, topsoil and soft clays be removed from the proposed pavement and oversize areas. Table 2 below summarizes the anticipated excavation depths at the boring locations. Excavation depths may vary and could be deeper.

Due to the N -Value of 4 near the surface, we recommend reworking a minimum of the upper 3 feet of the subgrade. Additionally, to further evaluate the suitability of the existing fill soils, if necessary, tests pits could be performed prior to or at the time of construction to further evaluate the quality of the fill in the pavement areas. Compaction bests could be performed on the fill within test pits confirm compaction is a minimum of 95 percent of Standard Proctor. Oversizing In areas where the excavations extend below the proposed pavement elevations, the excavation requires oversizing. We recommend the perimeter of the excavation be extended a foot outside the proposed footprint for every foot below pavement grade (1H:1V oversizing). The purpose of the oversizing is to provide lateral support of the pavements. Fill and backfill placed on slopes must be "benched" into the underlying suitable soil to reduce the potential for slip planes to develop between the fill and underlying soil. We 5 recommend "benching" or excavating into the slope at 5 feet vertical intervals to key the fill into the slope. We recommend each bench be a minimum of 10 feet wide. Fill Material Fill required to attain site grades may consist of any debris -free, non-organic mineral soil. Portions of the removed existing fill soils could be reused as engineered fill but will likely require moisture conditioning (drying). Constructing the pavements with a 2 foot thick sand subbase would provide a more stable and less frost susceptible pavement subgrade. We recommend using sand with less than 12% passing the #200 sieve, such as MN/DOT 3149.2B2 (Select Granular Borrow). If the sand sub -base is used we recommend the sub -base extend to 2 feet beyond the outside edges of the curbs/pavements for frost and drainage uniformity. Sand layers outside the pavements/curbs should be capped with slow draining soil to reduce surface water infiltration. If a sand sub -base is used in the pavement areas, drainpipes (finger drains) should be installed to remove infiltrating water. The finger drains should be connected to the catch basins. The slope of the bottom of the sub -cut should be such that water is directed to the drainage areas. The sub -cut bottom should not include depressions that can act as reservoirs for water collection. Backfilling We recommend that engineered fill placed to establish pavement grades be compacted to a minimum of 95 percent of its standard Proctor maximum dry density. The upper 3 feet of fill and backfill should be compacted to a minimum of 100 percent of its standard Proctor maximum dry density. We recommend compacting the backfill at moisture contents within a range of 1 percentage point above and 3 percentage points below its optimum moisture content. Granular fill classified as SP or SP -SM can be placed within 65 percent to 105 percent of its optimum moisture content as determined by the standard Proctor. All fill should be placed in thin lifts and be compacted with a large self-propelled vibratory compactor operating in vibratory mode. 4.4 Pavement Recommendations R -Value testing was beyond the scope of this project. The soil borings generally encountered existing fill and clay till soils consisting of predominantly of sandy lean clay soils near the surface corresponding to the ASTM Classifications CL. We assume the sandy lean clays will mainly comprise the pavement subgrades and recommend using an R -Value of 12 for pavement design. We recommend a light duty bituminous pavement section for the car parking lot consist of 1 % inches of bituminous wear, 2 Ih inches of bituminous base and 8 inches of aggregate base and the bituminous trail/bituminous shelter pad consist of 3 inches of bituminous wear and 6 inches of aggregate base. We recommend the concrete pavement section for the hockey rink/pickleball courts be at least 6 inches thick. We recommend the concrete be reinforced with rebar and have control joints with a maximum 10 foot by 10 foot grid. Additionally, we recommend a minimum of 6 inches of sub -base material be placed below the rink/concrete slab, consisting of imported Sand subgrade meeting MN/DOT specification 3138 (Class 5). Prior to placing the aggregate base (Class 5) we recommend observing a test roll of the subgrade soils with a loaded tandem truck to identify soft, weak, loose or unstable areas that may require additional subcuts. We recommend aggregate base meeting MN/DOT specification 3138 for Class 5 aggregate base. We recommend the aggregate base be compacted to 100 percent of its maximum standard Proctor dry density. We recommend that the bituminous wear and base courses meet the requirement of MN/ DOT specification 2360. We recommend the bituminous pavements be compacted to at least 92% of the maximum theoretical density. The hockey rink/pickleball courts will be a concrete slab and the car parking lot will include concrete curb and gutter. We recommend specifying concrete that has a minimum 28 day compressive strength of 3,900 psi. We recommend specifying 5 to 8 percent entrained air for exposed concrete to provide resistance to freeze -thaw deterioration. We recommend slump, air content and compressive strength testing of Portland cement concrete. 4S Utilities We anticipate new underground storm sewer utilities will be installed as part of the project. We anticipate that the utilities will be supported by engineered fill and/or glacial till soils which in our opinion are suitable for pipe support. We recommend removing all topsoil, existing fill soils, soft clays or other unsuitable soils, if encountered, beneath utilities prior to utility placement. We recommend bedding material be thoroughly compacted around the pipes. We recommend trench backfill above the pipes be compacted to a minimum of 95 percent beneath pavements, the exception being within 3 feet of the proposed pavement subgrade, where 100 percent of standard Proctor density is required. In landscaped areas we recommend a minimum compaction of 90 percent. Groundwater only encountered in soil boring 4 at a depth of 11 rh feet while drilling. This groundwater appears to have been perched with a sand seams of the soil. If groundwater is encountered during utility installations, we assume the volume of water will be relatively small and able to be removed with sumps or pumps 7 5.0 CONSTRUCTION CONSIDERATIONS 5.1 Excavation The existing fill soils and glacial till soils encountered in the borings generally correspond to the ASTM Classifications CL. The soils identified in the borings will generally be Type B soils under Department of Labor Occupational Safety and Health Administration (OSHA) guidelines. Temporary excavations should be constructed at a minimum of 1 foot horizontal to every 1 foot vertical within excavations. Slopes constructed in this manner may still exhibit surface sloughing. If site constraints do not allow the construction of slopes with these dimensions then temporary shoring may be required. 5.2 Observations A geotechnical engineer or qualified engineering technician should observe the excavation subgrade to evaluate if the subgrade soils are similar to those encountered in the borings and adequate to support the proposed construction. 5.3 Backfill and Fills Site soils that will be excavated and reused as backfill and fill appear to be above their assumed optimum moisture content We anticipate it will be necessary to moisture condition (dry) these soils to achieve the recommended compaction. We recommend that fill and backfill be placed in lifts not exceeding 4 to 12 inches, depending on the size of the compactor and materials used. 5.4 Testing We recommend density tests of backfill and fills placed during construction of the pavements. Samples of the proposed materials should be submitted to our laboratory prior to placement for evaluation of their suitability and to determine their optimum moisture content and maximum dry density (Standard Proctor). 5.5 Winter Construction If site grading and construction is anticipated to proceed during cold weather, all snow and ice should be removed from cut and fill areas prior to additional grading and placement of fill. No fill should be placed on frozen soil and no frozen soil should be used as fill or backfill. Concrete delivered to the site should meet the temperature requirements of ASPM and/or ACI. Concrete should not be placed on frozen soil. Concrete should be protected from freezing until the necessary strength is obtained. Frost should not be permitted to penetrate below the footings. 6.0 PROCEDURES 6.1 Soil Qassification The drill crew chief visually and manually classified the soils encountered in the borings in general accordance with ASPM D 2488, "Description and Identification of Soils (Visual - Manual Procedure)". Soil terminology notes are included in the Appendix. The samples were returned to our laboratory for review of the field classification by a geotechnical engineer. Samples will be retained for a period of 30 days. 6.2 Groundwater Observations Immediately after taking the final samples in the bottom of the borings, the hole was checked for the presence of groundwater. Again, at the end of the drilling day, the borings were rechecked for the presence of groundwater with the levels and time delay being noted on the boring logs. 7.0 GENERAL 7.1 Subsurface Variations The analyses and recommendations presented in this report are based on data obtained from a limited number of soil borings. Variations can occur away from the borings, the nature of which may not become apparent until additional exploration work is completed or construction is conducted. A reevaluation of the recommendations in this report should be made after performing on-site observations during construction to note the characteristics of any variations. The variations may result in additional foundation costs and it is suggested that a contingency be provided for this purpose. It is recommended that we be retained to perform the observation and testing program during construction to evaluate whether the design is as expected, if any design changes have affected the validity of our recommendations, and if our recommendations have been correctly interpreted and implemented in the designs, specifications and construction methods. This will allow correlation of the soil conditions encountered during construction to the soil borings and will provide continuity of professional responsibility. 7.2 Review of Design This report is based on the design of the proposed pavements as related to us for preparation of this report. It is recommended that we be retained to review the geotechnical aspects of the design and specifications. With the review we will evaluate whether any changes have affected the validity of the recommendations and whether our recommendations have been correctly interpreted and implemented in the design and specifications. 0 7.3 Groundwater Fluctuations We made water level measurements in the borings at the times and under the conditions stated on the boring logs. The data was interpreted in the text of this report. The period of observation was relatively short and fluctuations in the groundwater level may occur due to rainfall, flooding, irrigation, spring thaw, drainage, and other seasonal and annual factors not evident at the time the observations were made. Design drawings and specifications and construction planning should recognize the possibility of fluctuations. 7.4 Use of Report This report is for the exclusive use of the City of Chanhassen, Pioneer Engineering and their design team to use to design the proposed structures and prepare construction documents. In the absence of our written approval, we make no representation and assume no responsibility to other parties regarding this report. The data, analysis and recommendations may not be appropriate for other structures or purposes. We recommend that parties contemplating other structures or purposes contact us. 7.5 Level of Care Haugo GeoTechmcal Services, LLC has used the degree of skill and care ordinarily exercised under similar circumstance by members of the profession currently practicing in this locality. No warranty expressed or implied is made. 10 APPENDIX = Approximate Boring Location HaugoGeoTechnical Services.

They highlight soil limitations that affect various land uses and provide information about the properties of the soils in the survey areas. Soil surveys are designed for many different users, including farmers, ranchers, foresters, agronomists, urban planners, community officials, engineers, developers, builders, and home buyers. Also, conservationists, teachers, students, and specialists in recreation, waste disposal, and pollution control can use the surveys to help them understand, protect, or enhance the environment. Various land use regulations of Federal, State, and local governments may impose special restrictions on land use or land treatment. Soil surveys identify soil properties that are used in making various land use or land treatment decisions. The information is intended to help the land users identify and reduce the effects of soil limitations on various land uses. The landowner or user is responsible for identifying and complying with existing laws and regulations. Although soil survey information can be used for general farm, local, and wider area planning, onsite investigation is needed to supplement this information in some cases. Examples include soil quality assessments (http://www.nres.usda.gov/wps/portal/ nres/main/soils/health/) and certain conservation and engineering applications. For more detailed information, contact your local USDA Service Center (http:// offices.sc.egov.usda.gov/locator/app?agency=nres) or your NRCS State Soil Scientist (http://www.nres.usda.gov/wps/portal/nres/detail/soils/contactus/? cid=nres142p2_053951). Great differences in soil properties can occur within short distances. Some soils are seasonally wet or subject to flooding. Some are too unstable to be used as a foundation for buildings or roads. Clayey or wet soils are poorly suited to use as septic tank absorption fields. A high water table makes a soil poorly suited to basements or underground installations. The National Cooperative Soil Survey is a joint effortof the United States Department of Agriculture and other Federal agencies, State agencies including the Agricultural Experiment Stations, and local agencies. The Natural Resources Conservation Service (NRCS) has leadership for the Federal part of the National Cooperative Soil Survey. Information about soils is updated periodically. Updated information is available through the NRCS Web Soil Survey, the site for official soil survey information.

The map unit descriptions, along with the maps, can be used to determine the composition and properties of a unit. A map unit delineation on a soil map represents an area dominated by one or more major kinds of soil or miscellaneous areas. A map unit is identified and named according to the taxonomic classification of the dominant soils. Within a taxonomic class there are precisely defined limits forthe properties of the soils. On the landscape, however, the soils are natural phenomena, and they have the characteristic variability of all natural phenomena. Thus, the range of some observed properties may extend beyond the limits defined for a taxonomic class. Areas of soils of a single taxonomic class rarely, if ever, can be mapped without including areas of other taxonomic classes. Consequently, every map unit is made up of the soils or miscellaneous areas for which it is named and some minor components that belong to taxonomic classes other than those of the major soils. Most minor soils have properties similar to those of the dominant soil or soils in the map unit, and thus they do not affect use and management. These are called noncontrasting, or similar, components. They may or may not be mentioned in a particular map unit description. Other minor components, however, have properties and behavioral characteristics divergent enough to affect use or to require different management. These are called contrasting, or dissimilar, components. They generally are in small areas and could not be mapped separately because of the scale used. Custom Soil Resource Report Some small areas of strongly contrasting soils or miscellaneous areas are identified by a special symbol on the maps. If included in the database for a given area, the contrasting minor components are identified in the map unit descriptions along with some characteristics of each. A few areas of minor components may not have been observed, and consequently they are not mentioned in the descriptions, especially where the pattern was so complex that itwas impractical to make enough observations to identify all the soils and miscellaneous areas on the landscape. The presence of minor components in a map unit in no way diminishes the usefulness or accuracy of the data. The objective of mapping is not to delineate pure taxonomic classes but rather to separate the landscape into landforms or landform segments that have similar use and management requirements. The delineation of such segments on the map provides sufficient information for the development of resource plans. If intensive use of small areas is planned, however, onsite investigation is needed to define and locate the soils and miscellaneous areas. An identifying symbol precedes the map unit name in the map unit descriptions. Each description includes general facts about the unit and gives important soil properties and qualities. Soils that have profiles that are almost alike make up a soil series. Except for differences in texture of the surface layer, all the soils of a series have major horizons that are similar in composition, thickness, and arrangement. Soils of one series can differ in texture of the surface layer, slope, stoniness, salinity, degree of erosion, and other characteristics that affect their use. On the basis of such differences, a soil series is divided into soil phases. Most of the areas shown on the detailed soil maps are phases of soil series. The name of a soil phase commonly indicates a feature that affects use or management. For example, Alpha silt loam, 0 to 2 percent slopes, is a phase of the Alpha series. Some map units are made up of two or more major soils or miscellaneous areas. These map units are complexes, associations, or undifferentiated groups. A complex consists of two or more soils or miscellaneous areas in such an intricate pattern or in such small areas that they cannot be shown separately on the maps. The pattern and proportion of the soils or miscellaneous areas are somewhat similar in all areas. Alpha -Beta complex, 0 to 6 percent slopes, is an example. An association is made up of two or more geographically associated soils or miscellaneous areas that are shown as one unit on the maps. Because of present or anticipated uses of the map units in the survey area, it was not considered practical or necessary to map the soils or miscellaneous areas separately. The pattern and relative proportion of the soils or miscellaneous areas are somewhat similar. Alpha - Beta association, 0 to 2 percent slopes, is an example. An undifferentiated group is made up of two or more soils or miscellaneous areas that could be mapped individually but are mapped as one unit because similar interpretations can be made for use and management. The pattern and proportion of the soils or miscellaneous areas in a mapped area are not uniform. An area can be made up of only one of the major soils or miscellaneous areas, or it can be made up of all of them. Alpha and Beta soils, 0 to 2 percent slopes, is an example. Some surveys include miscellaneous areas. Such areas have little or no soil material and support little or no vegetation. Rock outcrop is an example.
