CAS-06_LAKE RILEY/RICE MARSH LAKE WATER QUALITY IMPROVEMENT FILE 1 OF 2Page 2 — Chanhassen Villager — Thursday, February 15, 2007 Chamber board maps out goals for upcoming year The 10 volunteer leaders that make up the 2007 Chanhassen Area Chamber of Commerce Board of Directors began the Planning process for 2007 back in the fall of 2006 during their strategic planning retreat. Re- cently, during the Chamber's Jan.23 luncheon meeting, Board Chair Mary Kay Rasmussen un- veiled the organization's goals for the year. The 2007 goals that are in- cluded in this year's program of work are outlined below: ■Redevelop the chamber's mem- bership investment schedule to offer increased flexibility by bundling chamber opportunities tailored to meet the individual needs and goals of our business members. ■ Align the Chanhassen Area Chamber of Commerce and Vis- itor's Bureau with the resources needed to enhance our business community that will allow us to further market the Chanhassen area and chamber member busi- nesses. ■ Provide educational and growth Opportunities for chamber mem- bers and members of the greater community. ■ Focus on strengthening part- nerships between the chamber, our city and state government officials plus enhance the op- portunities and partnerships between our schools and busi- ness community. ■ Recognize and celebrate some of the long-standing chamber member businesses that have helped the Chanhassen area become what it is today in an- ticipation of the Chamber's 5oth anniversary in 2010. In addition to the goals out- lined above, the chamber will Linda WALTON host in excess of 40 chamber - sponsored events during the year as well as continue to provide our members with marketing, networking, business referrals, legislative influence and a con- nections to our government. For those interested in what's happening in St. Paul during this legislative session, the chamber is for the second consecutive year providing our members the opportunity to learn the latest from the State Capitol through a legislative conference can series. A total of seven conference calls remain on the agenda with the next scheduled for Friday, Feb.16 beginning at 7:30 a.m. A "listen only" format will run from 7:30 to 7:45. At 7:45 a.m. alllines will be opened up to allow for the op- portunity to ask questions. The chamber office will be open at 7:15 a.m. Those interested in at- tending should arrive at least five minutes prior to the start time. For more information on the series and or for a list of confer- ence call dates, call the chamber at (952) 934-3903. Walton is the executive director of the Chanhassen Area Chamber of Commerce. Chamber supports retaining dinner theater The Chanhassen Area Chamber of Commerce Board of Directors in January unani- mously passed a resolution in support of keeping the Chanhassen Dinner Theatres in Chanhassen. According to the resolution: Whereas, the Chanhassen Area Chamber of Commerce recognizes that the Chanhassen Dinner Theatres provides an important cultural element to our community and, Whereas, the Chanhassen Area Cham- ber of Commerce understands that the Chanhassen Dinner Theatres contributes to the economic strength of our city and, Whereas, the Chanhassen Dinner Theatres adds to the viability of our downtown dis- trict, now, therefore, it is hereby resolved that the Chanhassen Area Chamber of Commerce supports continued efforts to retain the Chanhassen Dinner Theatres within Chanhassen. Pond project helps keep water clean By Teri Kelsh STAFF WRITER The Riley Purgatory Bluff Creek Watershed District is cleaning and expanding several stormwater ponds in Chanhassen to improve water quality in Rice Marsh Lake and Lake Riley. Work is already completed on three ponds in Rice Marsh Lake Park and one at West 78th Street and Chanhassen Road; and work just started on the last pond in the northwest corner of Highway 5 and Mar- ket Boulevard. The project involves up- grading the existing storm - water ponds by removing silt and whatever else that has accumulated in them over the years, said Lorie Haak, Chanhassen water resources coordinator. The overall cost of cleaning and upgrading the ponds is $1.1 million, said Bob Obermeyer, project engineer from Barr Engineering Company. The pond at Market Boule- vard is also being excavated to make it slightly larger and deeper to handle more storm water. It will also have a small area where a majority of the pollutants will be deposited, which will make it easier for city crews to routinely clean the pond. "A good portion of the storm water runoff from downtown Chanhassen goes through a network of pipes and empties into this pond. Over the years sand and trash builds up inplaces and then the pond doesn't function quite as well as it should," said Haak. There are 350 stormwater ponds in Chanhassen, and having them functioning prop- erly is crucial to having good water quality in lakes, rivers and streams, she said. All five ponds in the project collect storm water that emp- ties into Rice Marsh Lake and Lake Riley, and eventually into the Minnesota River. The ponds act as a trap filtering out pollutants picked up by the ini- tial surge of storm water. The sediments from the storm wa- ter settle to the bottom of the pond resulting in cleaner water when it leaves the pond. Crews have started excava- tion of the Market Boulevard pond, and residents may have VILLAGER PHOTO By TEPI KELSH Work is under way at the storm water pond in the northwest corner of Highway 5 and Market Boulevard Friday, Feb. 9. The work is part of an overall project initiated by the cities of Chanhassen and Eden Prairie to improve water quality in Lake Riley and Rice Marsh Lake. noticed a considerflble number of trucks hauling dirt from the site and traveling onto Market Boulevard. "The city's biggest concern is traffic in the area. We definitely see a need for the project; it ab- solutely needs to be done. People need to be aware of the work go- ing on because it's such a busy intersection," said Haak. Some traffic control measures are in place in the area including signs and flag men. Crews will be working longer hours on the pond then what's typically allowed for a construc- tion project in the city to decrease the overall duration of the proj- ect, said Bask. - "If it was closer to a residen- tial area it would be different, but the nearest residential area is probably a half -mile away," she said. Depending on weather condi- tions, the pond at Market Boule- vard should be complete in about two weeks, said Obermeyer. .

"I think it sucks," says the owner of Cy's Bar and Grill in Chaska. "Let the people make the choice. Let's vote on it." With that being said, Dircks says given the choice he would rather see a statewide ban than the way things are SMOKING BAN The Freedom to Breathe Act calls for an expanded smoking ban in indoor workplaces, including bars and restaurants and public transportation. Where you could smoke: It would be legal if you were a scientific study participant; in traditional Native American ceremonies; at private places such as your home and vehicle, if those are not used as a workplace; in hotel and motel rooms; and in tobacco product shops. It you violate it: Proprietors or building owners could face a misdemeanor charge if someone is smoking in their business. The smoker could face a petty misdemeanor_ Where should retail go? Council planning for future growth By Teri Kelsh STAFF WRITER The Chanhassen City Coun- cil is planning for commercial growth in the city and consider- ing how much growth should oc- cur outside the downtown area. A market study analysis conducted last year shows with the combination of Highway 212 and a boomingpopulation in the southwest suburbs, Chanhassen has the potential to attract more than 300,000 people living in nearby communities to shop in the city by 2010. We never wanted to be a regional draw, other than for the Arboretum and the dinner theater, but now we're actually thinking about it. It represents a paradigm shift," said Councilor Craig Peterson at a work session Monday night, Feb.12.

The construction is scheduled to start in early 2007 depending upon the weather. The excavation of the proposed pond would eliminate the existing property comers that may have been established in the wetland area. As part of this project, the District is hiring a registered land surveyor to establish on line property irons in your back yard adjacent to the existing trail. This work will be part of the project cost and there will be no charge to you. The Surveyor is scheduling this work for the first week in December. After the survey work is complete you will be supplied with a dimensioned drawing for your records. Please call me if you have any concerns or questions at 952-832-2857.

' The Owners and Contractor shall be responsible for full compliance with all of the terms and conditions of this SWPPP and the Project Specifications (Erosion Control Section 02373). 1.0 Project Information: Project Name: The proposed project is the Lake Riley/Rice Marsh Lake Water Quality Improvements Project being undertaken by the Riley -Purgatory -Bluff ' Creek Watershed District and the Cities of Chanhassen and Eden Prairie. Project Location: The project is located in the central portion of the City of Chanhassen and the west central portion of Eden Prairie. Sites are adjacent to Trunk Highway 5 and between Trunk Highway 5 and Lyman Blvd. on the south and between Dell Road on the east and Powers Blvd the west. There are five different proposed construction sites within this area. The proposed construction will take place within Sections 12 and 13 within Township 116 North, Range 23 West in Carver County and Hennepin County, Minnesota. All of the proposed construction sites are either adjacent to or within existing wetlands and near receiving waters. The purpose of the project is to maintain and improve the water quality of the downstream receiving water bodies, of Rice Marsh Lake, Lake Riley, and Riley Creek. Project Sites: 1. RM-1.1; Rice Marsh Lake Park and Dakota Lane. 2. RM-2.2; W. 78"' Street and Chanhassen Road 3. RM-2.5; Cheyenne Avenue and Dakota Lane 4. RM-2.6; Cheyenne Avenue and Dakota Lane 5. RM-6.5; Trunk Highway 5 and Market Blvd. 2 Project Size: The project will disturb a total of 9.5 acres of existing storm water ponds, wooded upland, wetland, and existing park land. The project will not increase the existing impervious surface with in the project area. Wetlands Mitigation: The proposed project provides replacement for the unavoidable wetland impacts, according to the WCA rules, to 142,950 square feet (3.28 acres) of wetlands associated with the project. The WCA requires a total of 285,900 square feet (6.56 acres) of wetland replacement to compensate for the wetland fill and excavation in and immediately adjacent to the five existing stormwater treatment areas. In addition, removal of accumulated sediment, to a depth no greater than the initial excavation, is proposed to take place in RM-2.5. The removal of this deposited sediment in a constructed stormwater basin qualifies for a No Loss Determination [Minnesota Rules 8420.0220 (f)]. Also, based on a review of historic photographs and precipitation data, it appears evident that the majority of Wetland RM-6.5 was created from historic upland area for purposes other than to create wetlands and therefore qualifies for WCA incidental exemption (Minnesota Rules 8420.0122, Subp. 5). The excavated stormwater pond/wetland has a current size of 146,670 square feet. However, the area of the historic Type 3 and Type 2 wetland, within the existing wetland area, had a total size of 54,895 square feet, Type 2 = 35,167 square feet; Type 3=19,728 square feet. The MnDNR has indicated that wetland impacts under their jurisdiction, impacts ' below an elevation of 877 M.S.L. within Rice Marsh Lake (Protected Water 10- IP), totaling 129,404 square feet (2.97 acres) will require replacement. These impacts may be compensated for by WCA and Corps required wetland mitigation ' and potential "self -mitigation" (1:1 ratio) for the excavation of the alteration/enhancement of stormwater treatment areas. ' Wetland mitigation planning was conducted in accordance with WCA replacement siting rules and guidelines from Section 404 of the Clean Water Act. The first consideration for wetland replacement was on -site, within the project areas. It is not feasible to include new wetland areas within the project area (that would adequately meet pretreatment requirements) because of current urbanization and current City plans for the west portion of Rice Marsh Lake Park. The next area that was ' considered for replacement was the minor watershed, which is the Riley -Purgatory - Bluff Creek Watershed. There are no wetland mitigation or banking opportunities ' available in the Riley -Purgatory -Bluff Creek Watershed. The next level for mitigation siting is within the major watershed. The Mueller wetland bank is one of four existing wetland banks located within the major watershed, Minnesota River — ' Shakopee, with sufficient credits available for sale to the public, and that has been approved by the Corps. The Corps has preliminarily indicated that all proposed project -related fill and ' excavation, within the existing/proposed five stormwater treatment areas will likely be regulated by the Corps, requiring compensation under the Clean Water Act. A total of 362,384 square feet (8.32 acres) of Corps -regulated wetland impacts is associated with the project. If wetland compensation is "in -place", "in -kind", and "in -advance", the Corps's minimum compensation ratio of 1:1 is acceptable. However, impacts proposed within Type 4 (71,909 square feet) and Type 6 (17,411 square feet) are planned to replaced "out -of -kind" (replaced with a different wetland type) with a replacement ratio is 1.5:1. Corps Impacts and Proposed Compensation wetland Type Type 2 Type 3 Type 4 Type 6 Impacts Required Impacts Required Impacts Required Impacts Required Compensation Compensation Compensation Compensation (1:1 ratio) (1:1 ratio) (1.5:1 ratio) (1.5:1 ratio) Totals (sq. 107,864 26,117 (17,411 fL) 86,968 86,%8 186,097 186,097 71,909 (71,909' 1.5) 17,411 • 15) Grand 362,384 406,995 Totals (sq. ft.) The mitigation for impacts under the Clean Water Act will be accomplished through a combination of wetland re-establishment/vegetation enhancement activities, and the purchase of wetland banking credits. A total of 295,419 square feet of stormwater management basins will be created/altered in five locations as part of the project. The Corps has indicated that a 50 percent credit for a total of 147,710 square feet (295,419 square feet./2) may be allowed. The remaining minimum mitigation requirement, 5.95 acres (259,335 square feet), is to be provided by the purchase of new wetland credits from the Mueller wetland bank, Account #1114. Mitigation for the proposed 3.28 acres of unavoidable WCA wetland impacts will include the purchase of 5.95 acres of new wetland credits previously mentioned above and public value credits, in the form of proposed new water quality treatment facilities within existing upland areas. A total of 0.84 acres (36,452 square feet) of new water quality treatment is proposed, which with the previously mentioned compensation meets the amount required by the WCA. The proposed wetland impact compensation amount will adequately compensate for 129,404 square feet (2.97 ac.) of MnDNR wetland impacts within their jurisdiction. Receiving Waters: The project is within the Riley -Purgatory -Bluff Creek Watershed District and will affect three receiving waters; Rice Marsh Lake, Lake Riley, and Riley Creek. All of these receiving waters are on the MPCA's Impaired Waters List but are not special waters. The purpose of this project is to maintain and improve the water quality of these lakes and stream. 4 Date of Construction: Construction is scheduled to start June 28, 2006 and continue over the winter months. Restoration will be completed in the spring 2007. Final completion is anticipated by June le, 2007. No construction activities shall commence until the permit coverage is in effect. Permit coverage will become effective seven (7) days after the postmarked date indicating when the Owner has mailed the completed NPDES Construction Activities application form to the MPCA. The installation and phasing of BMPs shall be discussed at the preconstruction meeting and installed before the start of any construction. 2.0 Contact Information: The following is a list of people that are responsible for this project and are knowledgeable and experienced in the application of erosion prevention and sediment control BMPs. They shall oversee the implementation of the SWPPP, inspection, and maintenance of erosion prevention, and sediment control BMPs before and during construction.

Final planting of shrubs, trees, and plants and restoration of disturbed area will be undertaken to complete the site. Remaining silt fencing will be removed after permanent cover has been established. 4.0 Erosion Prevention: t This project shall be executed in a manner to minimize erosion by using appropriate construction practices and phasing. Areas of the proposed sites and trees that will not be disturbed shall be delineated and marked prior to the start of construction ' Sediment control practices will be established on all down gradient perimeters prior to any land disturbing activities. At the beginning of the project, silt fences will be installed to prevent sediment from leaving disturbed areas. Once construction activities begin, ' temporary seeding/mulching of exposed soil areas will take place according to the MPCA guidelines for cover on exposed soils as stated below: ' Type of Slope Time (Maximum time an area can Remain open when the area Steeper than 3:1 7 days is not actively being worked.) ' 10:1 to 3:1 14 days Flatter than 10:1 21 days Weekly inspections of the site will take place or within 24 hours of a'/4-inch storm event of 0.25 inches or greater. Any repairs or corrective measures necessary to solve erosion problems will be completed within 24 hours. All erosion and sediment control practices shall remain in -place until final stabilization has been established. They shall be checked weekly to assure they are in proper working condition and not obstructing street drainage or causing street flooding. ' 5.0 Sediment Control Practices: ' All storm sewer inlets and outlets shall be protected by appropriate BWs during construction. These practices shall remain in place until the potential sources for discharging sediment to inlets have been stabilized. ' All temporary stockpiles and staging areas will have silt fence installed at their limits to prevent sediment from leaving the area All stockpiles that remain undisturbed ' for a period greater than one month shall be protected by covering with mulch, erosion mats, or plastic sheeting. Construction entrance, consisting of 1 %: to 2'/z inch washed rock pad and some with an additional bituminous landing will be built at the construction access point to each project to minimized vehicle tracking of sediment from the construction site. Construction entrances will be checked daily. If the rock becomes inundated with sediment, it will be cleaned or replaced. Streets leading to and from the construction entrance will be checked daily for evidence of off -site sediment tracking onto paved surfaces. These areas will be swept clean of any tracked materials as soon as possible and this work shall be completed within 24 ' hours of discovery. Sweeping shall extend to the extremity of any sediment tracking that occurs off site. ' 6.0 Dewatering and Basin Draining: Two of the sites RM-2.2 and RM-6.5 will have the existing basins drained prior to ' excavation. BMPs shall be used to prevent the transportation of sediments during pumping operations to draw down the basins. A Department of Natural Resources, Water Appropriation General Permit for dewatering and draining operations has been acquired for this project. Any dewaterng during the installation of utilities that may have turbid or sediment ' laden discharge water must be discharged to a detention basin for treatment. If this water can't be treated in a detention basin, it must be treated with appropriate BMPs such as dispersed over natural rock rip rap or sandbags. Any dewatering discharge can not adversely affect the receiving waters downstream of the construction site. ' 7.0 Inspection and Maintenance: The Site Supervisor and Contractor shall routinely inspect the construction site ' once every seven days during active construction and within 24 hours after a stone event of greater than ''/< inch rain within a 24 hour period. ' All erosion prevention and sediment control BMPs must be inspected to ensure integrity and their effectiveness. Any nonfunctional BMPs must be repaired, replaced or ' corrected with new practices. ' Silt fences will be repaired, replaced, or supplemented when they become nonfunctional or sediment has reached 1/3 the height of the fence. Accumulated silt will be ' removed and either is transported off -site or placed in protected areas that will not permit the sediment to impact other areas in the project site. These repairs shall be made within 24 hours of discovery, or as soon as field conditions permit. ' All inspections and maintenance conducted during construction will be recorded in writing and kept with the SWPPP until the end of the project. Records of each inspection and maintenance activities shall include the following and as specified in Section 02373 ' Erosion Control of the project specifications. Date and time of inspections: ' Names of persons conducting inspection: Findings of inspection, including recommendations for corrective actions: Corrective actions taken (including dates, time, party completing maintenance activities): Date and amount of all rainfall events of greater than Kinch in a 24 hours: Documentation of changes made to the SWPPP: Minnesota Pollution Control Agency's form Inspectors Log for MPCA Storm Water Permit may be used to record required inspections and rain fall events. See attached (Appendix D). 8.0 Pollution Prevention Management Measures: Solid waste such as collected sediment, asphalt and concrete millings, floating debris, paper, plastic fabric, construction and demolition debris and other wastes must be disposed of properly and must comply with MPCA disposal requirements. Hazardous materials use during construction on the development site; oil, gasoline, paint and hazardous substances must be properly stored, including secondary containment, to prevent spills, leaks or discharges. Any external washing of cement trucks, trucks and construction vehicles must be limited to a defined area of the site. 9.0 Final Stabilization: When construction activities have been completed on any of the sites, the final turf establishment shall be installed. All disturbed areas; side slopes, detention basin, and construction staging areas will be stabilized with the specified turf establishment per the plans and specifications. Methods to be used with this project shall be soding, seeding, mulching, and erosion mats for the permanent ground cover. All disturbed areas shall have a uniform perennial vegetative cover with a minimum density of 70 percent over the entire pervious surface area, or equivalent means necessary to prevent soil failure under erosive conditions. 10 1 1 1 1 1 1 The planned erosion controls measures shall be in -place at all the inlet and outlets. All permanent drainage culverts shall be checked and any accumulated sediment shall be removed from the culverts or receiving areas. The contractor shall remove all temporary synthetic and structural erosion prevention and sediment control BMPs. All silt fences, construction entrances, and other sediment controls shall be removed. Any accumulated sediment along silt fence shall be removed off of the project site and the ground established to preconstruction conditions. 10.0 Drawings and Specifications: The erosion control construction plan and details are on sheets C-02, C-06, C-08, C-10, C-13, and C-15 of the drawings.

The City of Eden Prairie submitted a similar petition concurrently. Several of the ponds will be constructed in conjunction with Trunk Highway 212 or future development. The remaining ponds are proposed to be part of this project, or have been eliminated due to the redesign of downstream facilities. In May 2005, a wetland delineation was completed by Barr Engineering. On June 23, 2005, City staff verified the delineated wetland boundaries. On July 28, 2005, City staff approved the wetland delineation for the areas where work will occur in conjunction with the proposed project. Two of the proposed ponds are within wetlands adjacent to Rice Marsh Lake. The Ordinary High Water Level (OHW) of Rice Marsh Lake is 877.0. Any wetland impacts occurring below the OHW require permits from the Minnesota Department of Natural Resources (DNR). WETLANDS Existing Wetlands Five wetland basins are proposed to be impacted within the project area. Basin RM-1.1 is located just south and west of Rice Marsh Lake Park. It is a Type 4/3/1 wetland adjacent to Rice Marsh Lake (DNR Protected Water 10-1P). The basin is dominated by reed canary grass, sandbar willow, cattail, black willow and box elder. Basin RM-2.1 is located adjacent to the railroad tracks, just north of Lotus Lawn and Garden. It is a Type 4 wetland dominated by open water and fowl bluegrass. Basin RM-2.5 is located just west of the Chanhassen/Eden Prairie border along a small ravine. It is a Type 4/6 wetland dominated by reed canary grass, box elder, red -osier dogwood, buckthorn, aspen and black willow. Basin RM-2.6 is located just south of Basin RM-2.5 adjacent to Rice Marsh Lake (DNR Protected Water 10-1P). It is a Type 4/2/3/6 wetland dominated by reed canary grass, Canada watermeal, sandbar willow and black willow. Basin RM-6.5 is located in the northwest quarter of Market Boulevard and Trunk Highway 101. It is a Type 4/3/2/6 wetland dominated by cattail, pondweed, reed canary grass, willow, red -osier dogwood and cottonwood. City Council Planning Case No. 06-06 April 10, 2006 Page 3 of 6 Wetland Impacts The proposed project proposes fill and excavation within all five wetland basins within the project area. Proposed wetland impacts are as follows: Basin 1.1 Excavation Excavation 'ype 3,4 or 5) (Not Type 3, 4 or 795 20,074 2.1 298 22,648 0 2.5 1,456 0 2,090 2.6 7,333 0 31,856 6.5 780 19,728 35,167 Total 10,592 43,171 89,187 The total amount of impact proposed by the project is 142,950 square feet (3.28 acres). Wetland Mitigation Wetland replacement is required at a 2 to 1 ratio (6.56 acres). The replacement of wetland will be accomplished through the withdrawal of 5.95 acres of New Wetland Credit (NWQ ;A,Atland credits from the Minnesota State Wetland Bank and the creation of 0.84 acres of Public Value Credit (PVC) through the construction of storm water ponds. The current proposal exceeds the required mitigation by 0.23 acres. ANALYSIS Initially, additional ponding sites were considered for this project. However, as the RPBCWD analyzed the sites, several sites were found to be unnecessary if existing downstream ponds were enlarged. By taking a more comprehensive regional ponding approach, the smaller ponds were eliminated. This reduced the cost of the project due to easement acquisition and site access difficulties. In addition, it will likely increase the effectiveness of the ponding while increasing the efficiency of future pond maintenance. The RPBCWD has not yet notified property owners near the proposed pond improvement projects of the work that will be done. The applicant must notify nearby property owners of the proposed project at least two weeks prior to beginning work. The notice should, at a minimum, provide a summary of the purpose of the project, the timeline for project completion, and contact information for someone with RPBCWD who is able to provide more information about the project. It is recommended that the applicant work with the City to identify property owners receiving notice and to provide a link to a project website from the City's website. The proposed project is dependent on access onto and across City property. The applicant should restore any disturbed areas and restore or replace any damage to infrastructure. Erosion Control All exposed soils from temporary haul routes, exposed slopes above the normal water level (NWL) and adjacent areas to the project must be temporarily stabilized and seeded within the 7, 14, 21 day time frames depending upon slopes. Any concentrated flow areas must receive City Council Planning Case No. 06-06 April 10, 2006 Page 4 of 6 temporary protection within 24 hours of connection to surface waters. Erosion control blanket should be used in concentrated flow areas and for slopes of 3:1. All remaining areas shall be mulched and seeded to control erosion. The applicant should provide information regarding the fate of the excavated/excess material, as well as the stabilization and/or containment of the material. Temporary energy dissipation should be installed at existing flared end sections to the bottom of the basin at the end of each day to protect against erosion. This could include temporary plastic sheeting or geotextile fabric secured to the soil. Sediment Control All existing outiets/proposed outlet structures should be temporary riser structures until the ponds and adjacent areas are stable. During excavation and work in the spring, rains may cause re -suspension of solids within the ponds. A temporary riser will ensure minimal sediment discharge will be possible. Street sweeping and scraping will be needed daily (potentially more often) during active haul times. A dedicated site pickup sweeper may be needed. Runoff Control/Dewaterine The applicant should provide details as to how dewatering will be accomplished for the basins in this project. A temporary standpipe and rock cone could be used to draw down the ponds, or a floating skimmer pump could be used. Initially the drawdown of the ponds will likely not be an issue. If it rains and re -suspension of sediment occurs the water will have to sit in the pond until it is clear enough to discharge to receiving waters. A standpipe and rock cone with the pump drawing water from the pipe would help minimize the lag time after a storm to begin drawing the ponds down again. The applicant should have a flocculent available on the project to facilitate sediment removal from sediment -laden water. Energy dissipation should be provided at all discharge points from dewatering pumps. Waters receiving dewatering discharges should be large enough to handle the volume and velocity of the water. Other A encies The applicant shall apply for and obtain permits from the appropriate regulatory agencies (e.g., Minnesota Pollution Control Agency (NPDES Phase II Construction Permit), Minnesota Department of Natural Resources (for dewatering; impacts below the OHW of Rice Marsh Lake), Minnesota Department of Transportation) and comply with their conditions of approval. City Council Planning Case No. 06-06 April 10, 2006 Page 5 of 6 FINANCING The cost of the improvements will be divided between the RPBCWD and the City. The City will be responsible for 75% of the costs for easement acquisition. RPBCWD will pay all other costs. The engineer's estimate for the construction of the 5 ponds is approximately $1,100,000. One easement will be necessary to complete this project. All other improvements are on City property. The total cost for easement acquisition is $15,000; the City's portion of the costs is 75% of that, or approximately $11,250. The City's portion of the improvement costs will be paid through the Surface Water Management Fund's Capital Improvement Program Property Acquisition item (SWMP-014). In 2006, $200,000 was allocated for the acquisition of property in accordance with the City's Comprehensive and Surface Water Management Plans.

December 9, 2005 Riley Purgatory Bluff Creek Watershed District C/o Mr. Bob Obermeyer, District Engineer Ban- Engineering Company 4700 W. 77th Street Minneapolis, MN 55435-4803 RE: Potential Wetland Impacts for the Lake Susan/Rice Marsh Lake Water Quality Improvement Projects Dear Mr. Obenneyer This letter serves as BWSR's official determination of wetland impacts related to the Lake Susan and Rice Marsh Lake Water Quality Improvement Projects. According to draft project plans presented by Mark Wilson and Bob Obermeyer of Barr Engineering, the District is proposing to treat stormwater runoff by increasing dead storage via berms and excavation within wetlands. The Minnesota Wetland Conservation Act (WCA) Rules Chapter 8420.0105 "Scope" section, states "...This chapter regulates excavation... in all wetland types if excavation includes filling or draining or results in conversion to nonwetland." In addition, according to the WCA definition of "project", "...A project may not be split into components or phases for the sole purpose of gaining additional exemptions " Therefore this project as proposed on the attached sheets would require sequencing and full 2:1 mitigation for all combined fill and excavation activities within the wetland boundary above the Ordinary High Water Mark (or for combined activities in their entirety if DNR categorically waives jurisdiction to WCA). Please feel free to contact me with additional questions.

Site RM-1.1 will include excavation, grading, and installation of a siltation sock system below the OHW so this will require a DNR Waters permit. I've talked to Larry Zdon (PCA, 651-297-8219); he says that the siltation sock system might be considered an Alternative Method by PCA--he couldn't make that determination, though, unless he sees details of the plans. Access to this site will be necessary for monitoring and maintenance.

The project proposes to construct new storm water basins and enhance existing basins to provide water quality treatment of storm water prior to reaching Lake Riley and Rice Marsh Lake. In your area, the project proposes to expand and deepen the existing open water area within Rice Marsh Lake. The edge of the open water area will not come any closer to the existing bituminous path than currently exists but the open water will extend further into the existing wetland. The enclosed drawing shows the location of both the existing and proposed open water area. All of the work will be within the existing drainage easement area on your property. Also, enclosed is the plan sheet that shows the overall relationship of the work to the surrounding area. It is anticipated that this work will not be undertaken until the 2006-2007 winter months. Frozen ground conditions are necessary for stability in excavating the open water. The bituminous trail will provide the access to the area for construction. We would be happy to meet with you to discuss the project further with you.

RELFA B C 0 1 2 3 NO Bf N APP DATE REVISION DESCRIPTION LUTE RELEASED �P City Council Meeting — April 10, 2006 about it was the understanding that we weren't the only source that they were coming to to try to get this project done and indeed they are receiving support from a variety of sources. The Met Council just a few meetings ago presented a $300,000 grant for this project to the City so I think that's important too that it takes a lot of people to get these things done and a lot of organizations. A year or so ago when we were asked to support the group and the development in the form of a letter for the application, it was kind of a trust us and I think we looked at it as an opportunity. As a city we've always looked at these more as opportunity driven then using a broad brush to meet these goals. And I think we're comfortable then saying that we do and I haven't seen anything over the last year with the site plan approval, especially in other things that we made a mistake then and I think this is just something, I'm glad to hear that this is something that we can support as a council. So with that we look forward to the ground breaking this fall and a nice new apartment building coming up in our city and also expanding some of the affordable units within our housing so. Appreciate everybody's effort on this from staff. Mr. Miller I know has spent a lot of time and Mr. Gerhardt and others and Ehlers and Associates and Sand Company as well. We appreciate all the effort that you put in to get us to this point so thank you very much for that. Any other comments? Questions. If not, is there a motion to approve? Roger Knutson: Recommended resolution. Councilman Lundquist: I would move approval of the attached resolution in the staff report to create Tax Increment Financing District #9. Councilman Labatt: Second. Mayor Furlong: Thank you. Is there any discussion on that motion? Resolution #2006-29: Councilman Lundquist moved, Councilman Labatt seconded that the City Council approve the resolution adopting a modification to the redevelopment plan for the downtown Chanhassen Redevelopment Project Area and establishing Tax Increment District No. 9 therein and adopting a tax increment financing plan therefore. All voted in favor and the motion carried unanimously with a vote of 4 to 0. LAKE RILEY/RICE MARSH WATER QUALITY IMPROVEMENT, APPLICANT STORM WATER PONDS FOR THE PURPOSE OF IMPROVING WATER QUALITY IN RICE MARSH LAKE AND LAKE RILEY WATERSHEDS. Lori Haak: Thank you Mayor Furlong and council members. The applicant, who is the Riley - Purgatory -Bluff Creek Watershed District is proposing the excavation and maintenance of 5 storm water ponds in the City of Chanhassen for the purposes of improving water quality in Rice Marsh Lake and Lake Riley, downstream. The wetland alteration permit is necessary because the applicant proposes the excavation and fill of existing wetlands to the order of 3.28 acres total in five locations. The applicant is proposing mitigation through the State Wetland Bank at a ratio of 2 to 1. The Planning Commission held a public hearing on March 21, 2006 to review the City Council Meeting — April 10, 2006 proposed wetland alteration. Several residents with property near the wetlands, adjacent to Rice Marsh Lake appeared to obtain additional information about the project. One property owner in particular, the owner of 8131 Dakota Lane expressed concern that the project proposed excavation on his property but that he had not received prior notification from the watershed district that the project would impact his property. His 8131 Dakota is located, it's the furthest left property that's outlined in red on the area photo here. That's correct, yes. During the Planning Commission meeting, the plat from the Hidden Valley subdivision was reviewed by staff and it was found that a drainage and utility easement covers the rear portion of the yard. Actually if you want to flip it over. Again the property at 8131 Dakota is the furthest to the left on your screen the utility easement, which contains the city's sanitary sewer, is located in the easement that is highlighted in orange and the drainage and utility easement is highlighted in pink on that drawing. So because there are existing drainage and utility easements in that location, the project does not propose impacts to property for which additional easements or land acquisition would be necessary. In response to the lack of communication with affected residents, the Planning Commission recommended adding a condition to the conditions of approval that would require the applicant to obtain all appropriate easements and permissions from affected property owners. Since that meeting city staff has spoken with the applicant regarding the concerns of the condition and the affected resident. The applicant has agreed to communicate with those 3 affected property owners prior to construction beginning. So even though we have the right to, or the applicant, or the public has the right to construct these ponds and in fact just expand an existing pond, they will be working, the applicant will be working with the residents in that area. The Planning Commission voted 5-0 to recommend approval of the proposed project subject to the conditions in the staff report, plus an additional condition 14 which reads, all appropriate easements and permissions must be obtained prior to commencing work. And with that staff and the Planning Commission recommend adoption of the motion as printed in the staff report, conditions 1 through 14. With that I'd be more than happy to take any questions you have. Mayor Furlong: Thank you. Any questions for staff? Just one and that corresponds to the last picture that was up on the table there with regard to the different easements. Seeing that now with the orange portion that delineates the utility, the sanitary sewer is there, is there any anticipation that there's going to be interruption in the service? Lori Haak: Not at all. Actually the existing trail, if we go back to the previous exhibit, is within the drainage and utility easement and all work would be done south of that trail. So, and actually in looking at the grading plans, staff has found that actually a good portion of that slope right along the trail will remain undisturbed, so. Mayor Furlong: And I guess that's in addition to not planning any interruptions, we're going to make sure we avoid them. Lori Haak: Absolutely. Mayor Furlong: Accidental ones. Lori Haak: Yes. 10 "WOA33 City Council Meeting — Ap•10, 2006 Mayor Furlong: Alright. Thank you. Any other questions for staff? On this. Councilman Labatt: Lori, what is the plan with the stuff that's removed from the ponds? Lori Haak: At this time the applicant has not selected a contractor and until that contractor is selected, they're not certain what the fate of that material will be, but one of the conditions in the staff report is that the city be made aware of that, not only the haul routes but also the final destination of that material. Mayor Furlong: This work is being done entirely by the watershed district, correct? And funded out of the watershed district. Lori Haak: That's correct. Mayor Furlong: It's an expansion of existing ponds... improve water quality downstream as well? Lori Haak: That's correct. Mayor Furlong: Okay, thank you. Lori Haak: And condition 6, Councilman Labatt is the condition that speaks to that. Mayor Furlong: Okay. Thank you. Is there any other questions or discussion? Any discussion on the matter? Councilman Labatt: No. Mayor Furlong: I think it's a good project. Councilman Lundquist: Yeah, just the communication piece I think is a good thing. I mean it never hurts to over communicate, especially when you haul in back hoes and bulldozers into somebody's back yard. It's usually good to let them know what's going on so. Mayor Furlong: Very good. Any other discussion or items? If not, is there a motion to approve? Councilwoman Tjomhom: Motion to approve the Wetland Alteration Permit #06-06 subject to the following conditions, 1 through 14. Mayor Furlong: Thank you. Is there a second? Councilman Lundquist: Second. Mayor Furlong: Made and seconded. Any discussion? 11 City Council Meeting — Ap�10, 2006 • Councilwoman Tjornhom moved, Councilman Lundquist seconded that the City Council approve Wetland Alteration Permit #06-06, subject to the following conditions: 1. Wetland replacement shall occur in a manner consistent with the Minnesota Wetland Conservation Act (MR 8420) at a ratio of 2:1. 2. The applicant shall notify nearby property owners of the proposed project at least two weeks prior to beginning work. The notice shall, at a minimum, provide a summary of the purpose of the project, the timeline for project completion, and contact information for someone with RPBCWD who is able to provide more information about the project. It is recommended that the applicant work with the City to identify property owners receiving notice and to provide a link to a project website from the City's website. 3. The applicant shall restore any disturbed areas and restore or replace any damage to infrastructure on City property. 4. All exposed soils from temporary haul routes, exposed slopes above the normal water level (NWL) and adjacent areas to the project shall be temporarily stabilized and seeded within the 7, 14, 21 day time frames depending upon slopes. Any concentrated flow areas shall receive temporary protection within 24 hours of connection to surface waters. 5. Erosion control blanket shall be used in concentrated flow area and for slopes of 3:1. All remaining areas shall be mulched and seeded to control erosion. 6. The applicant shall provide information regarding the fate of the excavated/excess material, as well as the stabilization and/or containment of the material. Temporary energy dissipation shall be installed at existing flared end sections to the bottom of the basin at the end of each day to protect against erosion. This could include temporary plastic sheeting or geotextile fabric secured to the soil. 8. All existing outlets/proposed outlet structures shall be temporary riser structures until the ponds and adjacent areas are stable. 9. Street sweeping and scraping shall be needed daily (potentially more often) during active haul times. A dedicated site pickup sweeper may be needed. 10. The applicant shall provide details as to how dewatering will be accomplished for the basins in this project. 11. The applicant shall have a flocculent available on the project to facilitate sediment removal from sediment laden water. 12 City Council Meeting — Ap9 10, 2006 12. Energy dissipation shall be provided at all discharge points from dewatering pumps. Waters receiving dewatering discharges should be large enough to handle the volume and velocity of the water. 13. The applicant shall apply for and obtain permits from the appropriate regulatory agencies (e.g. Minnesota Pollution Control Agency (NPDES Phase H Construction Permit), Minnesota Department of Natural Resources (for dewatering, impacts below the OHW of Rice Marsh Lake), Minnesota Department of Transportation, and comply with their conditions of approval. 14. All appropriate permissions and easements must be obtained prior to the undertaking of any construction. All voted in favor and the motion carried unanimously with a vote of 4 to 0. LIBERTY AT CREEKSIDE,1500 PIONEER TRAIL, APPLICANT TOWN & COUNTRY HOMES: REOUEST FOR REZONING OF PROPERTY FROM A2 TO PUD-R; SUBDIVISION WITH VARIANCES OF APPROXIMATELY 36.01 ACRES Public Present: Name Address Shawn Siders Town and Country Homes Kevin Clark Town and Country Homes Robert Nordby Town and Country Homes Bruce Jeurissen 1500 Pioneer Trail Kate Aanenson: The subject site located north of Pioneer Trail. West of the future Powers Boulevard. Oh, I need to use this so, if you don't mind. And Town and Country Homes is the applicant. This request is for 146 town home units and this item did appear before the Planning Commission on March 2151. Actually it appeared numerous months before that but there was a lot of work that needed to be done before we actually, were able to process the application. At the Planning Commission meeting, while they did vote 5-0 there were two main issues that they discussed. One was the access to the site. The two way access points, and the architecture. Existing site conditions, if you look at the property, the Jeurissen property has an existing driveway to the site that serves the homestead and that driveway shows up in this area, and that driveway is part of the MnDot agreement. It's allowed to maintain the use as a single driveway is typical. Once the use has changed and higher use is developed, it is the intent of that driveway to go away. The Planning Commission, this is the subject site again right here, and the issue that has come up on this property, it's providing a two way access and I want to spend a little bit of time on that issue in itself and go back and tie it back into the AUAR before we start talking 13 LqP rn L- ' ?e-a--E'j D meo /N6 9 A' .C.4- LNCs /N rQ-{N G — 1/D, N A q•Zo.o(, ,2PM —z•y—r,)4- IL GLOSU/Lrr- vt, CLoiuP.p - AotpC, A7 6eTrt F-Vpr- NITrPY CrTy IN AkDVANCF, No-CIw,N6 3 e"Oo&f+-Cy 6wr+E.f_ ,LL,-r P-A1>=6NCe- Pr-vNr; TR-alL� 2 •� � i2Av lri N G Lo-r FOt A Cr- f-SS .

PLANNING COMMISSION SUMMARY i 0l S1 o [ ni7onS. The Planning Commission held a public hearing on Ma h, 006 to review the proposed wetland alterations. Several residents with prope near the wetlands adjacent to Rice Marsh Lake appeared to obtain additional information about the project. The property owner at 8131 Dakota Lane expressed concern that the project proposed excavation on his property, but that he did not receive prior notification from the watershed district that the project would impact his property. The plat for the Hidden Valley subdivision was reviewed by staff during the meeting and it was found that a drainage and utility easement covers the rear portion of his yard. Because a drainage and utility easement was dedicated with the plat, the project does not propose impacts to the property for which additional easements or land acquisition would be necessary. In response to the lack of communication with affected residents, the Planning Commission recommended adding a condition to the conditions of approval that would require the applicant to obtain all appropriate easements and permissions from affected property owners. The Planning Commission voted 5 to 0 to recommend approval of the proposed project subject to the conditions of the staff report plus condition 14, which reads: "All appropriate easements and permissions must be obtained prior to commencing work."

The Planning Commission conducted a public hearing on the proposed development which was preceded by published and mailed notice. The Planning Commission heard testimony from all interested persons wishing to speak. The Planning Commission has made recommendations to the City Council. The Chanhassen City Council now makes the following: FINDINGS OF FACT 1) The properties are currently zoned RSF (Residential Single Family), BH (Highway and Business Services) and BN (Neighborhood Business). 2) The properties are guided by the Land Use Plan for commercial and parks/open space. 3) The properties are located in Chanhassen, Minnesota (Sections 12 and 13, Township 116 North, Range 23 West), Carver and Hennepin Counties: (a) One (1) storm water pond in the southeast quarter of the southeast quarter of Section 12; (b) One (1) storm water pond in the northwest quarter of the northwest quarter of Section 13; (c) One (1) storm water pond in the southwest quarter of Section 13; and (d) Two (2) storm water ponds in the southeast quarter of Section 13. 4) One natural wetland, one ag/urban wetland and one utilized wetland are located on the subject properties. 5) The total amount of wetland impact proposed is 142,950 square feet (3.28 acres). 6) The replacement of wetland at a 2:1 ratio will be accomplished through the withdrawal of wetland credits from the Minnesota State Wetland Bank and storm water ponding for public value credits. 7) Section 20-404 of the City Code stipulates that there should be no net loss of wetlands.

The City of Eden Prairie submitted a similar petition concurrently. Several of the ponds will be constructed in conjunction with Trunk Highway 212 or future development. The remaining ponds are proposed to be part of this project, or have been eliminated due to the redesign of downstream facilities. In May 2005, a wetland delineation was completed by Barr Engineering. On June 23, 2005, City staff verified the delineated wetland boundaries. On July 28, 2005, City staff approved the wetland delineation for the areas where work will occur in conjunction with the proposed project. Two of the proposed ponds are within wetlands adjacent to Rice Marsh Lake. The Ordinary High Water Level (OHW) of Rice Marsh Lake is 877.0. Any wetland impacts occurring below the OHW require permits from the Minnesota Department of Natural Resources (DNR). WETLANDS Existing Wetlands Five wetland basins are proposed to be impacted within the project area. Basin RM-1.1 is located just south and west of Rice Marsh Lake Park. It is a Type 4/3/1 wetland adjacent to Rice Marsh Lake (DNR Protected Water 10-1P). The basin is dominated by reed canary grass, sandbar willow, cattail, black willow and box elder. Basin RM-2.1 is located adjacent to the railroad tracks, just north of Lotus Lawn and Garden. It is a Type 4 wetland dominated by open water and fowl bluegrass. Basin RM-2.5 is located just west of the Chanhassen/Eden Prairie border along a small ravine. It is a Type 4/6 wetland dominated by reed canary grass, box elder, red -osier dogwood, buckthorn, aspen and black willow. Basin RM-2.6 is located just south of Basin RM-2.5 adjacent to Rice Marsh Lake (DNR Protected Water 10-1P). It is a Type 4/2/3/6 wetland dominated by reed canary grass, Canada watermeal, sandbar willow and black willow. Basin RM-6.5 is located in the northwest quarter of Market Boulevard and Trunk Highway 101. It is a Type 4/3/2/6 wetland dominated by cattail, pondweed, reed canary grass, willow, red -osier dogwood and cottonwood. City Council Planning Case No. 06-06 April 10, 2006 Page 3 of 6 Wetland Impacts The proposed project proposes fill and excavation within all five wetland basins within the project area. Proposed wetland impacts are as follows: Excavation Excavation Basin Fill (Type 3, 4 or 5) (Not Tvpe 3.4 t 1.1 725 795 20,074 2.1 298 22,648 0 2.5 1,456 0 2,090 2.6 7,333 0 31,856 6.5 780 19,728 35,167 Total 10,592 43,171 89,187 The total amount of impact proposed by the project is 142,950 square feet (3.28 acres). Wetland Mitigation Wetland replacement is required at a 2 to 1 ratio (6.56 acres). The replacement of wetland will be accomplished through the withdrawal of 5.95 acres of New Wetland Credit (NWC) wedead credits from the Minnesota State Wetland Bank and the creation of 0.84 acres of Public Value Credit (PVC) through the construction of storm water ponds. The current proposal exceeds the required mitigation by 0.23 acres. ANALYSIS Initially, additional ponding sites were considered for this project. However, as the RPBCWD analyzed the sites, several sites were found to be unnecessary if existing downstream ponds were enlarged. By taking a more comprehensive regional ponding approach, the smaller ponds were eliminated. This reduced the cost of the project due to easement acquisition and site access difficulties. In addition, it will likely increase the effectiveness of the ponding while increasing the efficiency of future pond maintenance. The RPBCWD has not yet notified property owners near the proposed pond improvement projects of the work that will be done. The applicant must notify nearby property owners of the proposed project at least two weeks prior to beginning work. The notice should, at a minimum, provide a summary of the purpose of the project, the timeline for project completion, and contact information for someone with RPBCWD who is able to provide more information about the project. It is recommended that the applicant work with the City to identify property owners receiving notice and to provide a link to a project website from the City's website. The proposed project is dependent on access onto and across City property. The applicant should restore any disturbed areas and restore or replace any damage to infrastructure. Erosion Control All exposed soils from temporary haul routes, exposed slopes above the normal water level (NWL) and adjacent areas to the project must be temporarily stabilized and seeded within the 7, 14, 21 day time frames depending upon slopes. Any concentrated flow areas must receive City Council Planning Case No. 06-06 April 10, 2006 Page 4 of 6 temporary protection within 24 hours of connection to surface waters. Erosion control blanket should be used in concentrated flow areas and for slopes of 3:1. All remaining areas shall be mulched and seeded to control erosion. The applicant should provide information regarding the fate of the excavated/excess material, as well as the stabilization and/or containment of the material. Temporary energy dissipation should be installed at existing flared end sections to the bottom of the basin at the end of each day to protect against erosion. This could include temporary plastic sheeting or geotextile fabric secured to the soil. Sediment Control All existing outlets/proposed outlet structures should be temporary riser structures until the ponds and adjacent areas are stable. During excavation and work in the spring, rains may cause re -suspension of solids within the ponds. A temporary riser will ensure minimal sediment discharge will be possible. Street sweeping and scraping will be needed daily (potentially more often) during active haul times. A dedicated site pickup sweeper may be needed. Runoff Control/Dewaterine The applicant should provide details as to how dewatering will be accomplished for the basins in this project. A temporary standpipe and rock cone could be used to draw down the ponds, or a floating skimmer pump could be used. Initially the drawdown of the ponds will likely not be an issue. If it rains and re -suspension of sediment occurs the water will have to sit in the pond until it is clear enough to discharge to receiving waters. A standpipe and rock cone with the pump drawing water from the pipe would help minimize the lag time after a storm to begin drawing the ponds down again. The applicant should have a flocculent available on the project to facilitate sediment removal from sediment -laden water. Energy dissipation should be provided at all discharge points from dewatering pumps. Waters receiving dewatering discharges should be large enough to handle the volume and velocity of the water. Other Agencies The applicant shall apply for and obtain permits from the appropriate regulatory agencies (e.g., Minnesota Pollution Control Agency (NPDES Phase II Construction Permit), Minnesota Department of Natural Resources (for dewatering; impacts below the OHW of Rice Marsh Lake), Minnesota Department of Transportation) and comply with their conditions of approval. City Council Planning Case No. 06-06 April 10, 2006 Page 5 of 6 FINANCING The cost of the improvements will be divided between the RPBCWD and the City. The City will be responsible for 75% of the costs for easement acquisition. RPBCWD will pay all other costs. The engineer's estimate for the construction of the 5 ponds is approximately $1,100,000. One easement will be necessary to complete this project. All other improvements are on City property. The total cost for easement acquisition is $15,000; the City's portion of the costs is 75% of that, or approximately $11,250. The City's portion of the improvement costs will be paid through the Surface Water Management Fund's Capital Improvement Program Property Acquisition item (SWMP-014). In 2006, $200,000 was allocated for the acquisition of property in accordance with the City's Comprehensive and Surface Water Management Plans.

According to draft project plans presented by Mark Wilson and Bob Obermeyer of Barr Engineering, the District is proposing to treat stormwater runoff' by increasing dead storage via beans and excavation within wetlands. The Minnesota Wetland Conservation Act (WCA) Rules Chapter 8420.0105 "Scope" section, states "...This chapter regulates excavation —in all wetland types if excavation includes filling or draining or results in conversion to nonwetland." In addition, according to the WCA definition of "project", `x...A project may not be split into components or phases for the sole purpose of gaining additional exemptions." Therefore this project as proposed on the attached sheets would require sequencing and full 2:1 mitigation for all combined fill and excavation activities within the wetland boundary above the Ordinary High Water Mark (or for combined activities in their entirety if DNR categorically waives, jurisdiction to WCA). Please feel free to contact me with additional questions.

Site RM-1.1 will include excavation, grading, and installation of a siltation sock system below the OHW so this will require a DNR Waters permit. I've talked to Larry Zdon (PCA, 651-297-8219); he says that the siltation sock system might be considered an Alternative Method by PCA--he couldn't make that determination, though, unless he sees details of the plans. Access to this site will be necessary for monitoring and maintenance.

PUBLIC HEARING: LAKE RILEURICE MARSH LAKE WATER OUALITY IMPROVEMENT: REOUEST FOR A WETLAND ALTERATION PERMIT FOR EXCAVATION AND MAINTENANCE OF FIVE (5) STORM WATER PONDS FOR THE PURPOSE OF IMPROVING WATER OUALPI'Y IN THE RICE MARSH LAKE AND LAKE RILEY WATERSHEDS, PLANNING CASE NO.06-06, RILEY-PURGATORY-BLUFF CREEK WATERSHED DISTRICT. Public Present: Name Address Ken & Liz Nystrom Bob Myers Kathy Slavics 8501 Tigua Lane 8131 Dakota Lane 8140 Dakota Lane Lori Haak presented the staff report on this item. Sacchet: Thanks Lori. Questions, Dan. Keefe: I've got a couple questions. First one, can you list, how does expanding, it looks like most of these ponds are going to be expanded and enlarged, right so how does that then translate to clearer water in Rice Marsh Lake? Are we going deeper? Maybe you can just show me, give me an example. Runoff goes in. Sand gets trapped wherever then it goes out. Real simple. Haak: Yeah, that's exactly right. I don't have to say much more than that. Yeah, the primary functions of storm water ponds is to trap the sediment, the big particles so not only trash but also the sand from road salt applications and things like that. The other is for nutrient removal, and so when you have, especially when you have a larger pond with a little bit more residents time, the very find particles can settle out and in fact vegetation has a big part to play in removing some of those nutrients before the water goes on to the next part in the system, whether it's Rice Marsh Lake or Lake Riley. So really by getting a big pond, what we're doing is consolidating... The original proposal for, that the watershed district brought forth included a lot of storm water ponds. Actually some in rear yards off of places like Marsh Drive and Lake Drive, off of commercial pieces and things like that, and what they were able to do by having a little bit more wetland impact, they were able to leverage a bigger area so for maintenance purposes and just construction feasibility purposes, they could consolidate those. In addition there's some evidence that regional ponding is more effective than water quality treatment so, that's kind of. Keefe: Where does all the fill go? 4 WANNE0 Planning Commission Meeting — March 21, 2006 Haak: That is up to the watershed district because they are the project proposers so, that is something that we conditioned. It's recommended as a condition by staff is that they cooperate with staff and let us know where that material is going. Keefe: Does it stay in the city here? Haak: Not necessarily. In some cases it does and in some cases it doesn't. It depends on the contractor they end up getting and where they have a home for that material. Keefe: Okay. And then just help me understand the wetland bank piece. If we're creating larger wetlands, are we creating larger wetlands or are we not creating? Haak: Actually these are wetland impacts because we're excavating wetland to turn it into storm water ponds. So the wetland banking. Keefe: Okay. Not one, they aren't the same? Haak: No, no. No, they have different regulatory standing so yeah. Keefe: Alright, so because we're impacting wetlands and turning them into storm water ponds, we essentially are reducing the amount of wetland right? Haak: Correct. And the required mitigation rate for wetland impacts is 2 to 1, so the watershed district is actually buying over 6 acres of credit in order to mitigate for this project, and those credits are already constructed. They're already in the state wetland bank so we're actually getting 2 to 1. Unfortunately it's not in Chanhassen, but we are getting some really good water quality improvements in the opinion of staff. Keefe: Okay, great. Sacchet: Any other questions? Jerry. McDonald: Yeah, I've got some questions. These retaining ponds are mainly to clear up the water going into Lake Riley, is that correct? Haak: Well Rice Marsh Lake and Lake Riley, correct yes. McDonald: And it's storm water that actually fills the ponds. Haak: Correct. McDonald: Now last year I know we had some problems with water over in this area as far as you know some flooding and everything. Is this going to help those types of situations? Haak: Well is there one specific pond that you're thinking of or? 0 0 Planning Commission Meeting — March 21, 2006 McDonald: No. In the area over around Lake Drive I believe, in that development when we had the big storm, there were some issues with water. Haak: Boy, I'm not. McDonald: Okay, I could be wrong but, will this begin to help some of those problems as far as keeping flooding down to a minimum? Haak: Well the great thing about two of these ponds is that they're adjacent to large water bodies that have a lot of holding capacity, so in keeping these ponds down lower in the watershed, we're able to storm much more water and yes, in excavating these there will be some water quantity benefit, but the primary benefit is going to be water quality in most cases. McDonald: Okay. And in relation to last year's storm, considered a 100 year event, how will these help the city as far as managing water during a storm of that kind of capacity and everything? Haak: Sure. The only one of these basins that I'm aware of that caused problems, or experienced any sort of problem in those two storms of last year is the Market Boulevard pond. There was some water that ran across Market Boulevard. Currently it runs under Market in most scenarios, toward the east. To the pond that's just right, just south of Applebee's and Walgreen's there, and in several cases, actually I think in both of those storms there was water in the street. Now that's again, that's the only one, and between Alyson and I we received a good number of calls on storm water and that's the only one that I'm aware of. In this case, I'm not sure that in a storm that large that this will help in a significant fashion, but there will be some benefit from that, from those excavations. Alyson, can you speak to that or are you aware of any additional problems? Fauske: The only other problem that I'm aware of was on south of Lake Drive East just off Cheyenne Avenue. That little eyebrow cul-de-sac area. There was a gentleman who we did go out and talk to. Basically the issue is, is his garage is lower than the street in the low point of the road drains towards the park back there and went through his back yard and so he had water going down his driveway. But I mean as far as speaking to these projects and the ability to help that situation, that's why we don't allow garages lower than the street anymore. Just because of situations like that where we have those huge events that our storm sewers aren't designed to handle that. McDonald: Okay. But will this improve our capability you know just any amount or? Fauske: Yes. McDonald: I have no further questions. Sacchet: Any questions? 0 A Planning Commission Meeting — March 21, 2006 Undestad: One quick one. The stone ponds, you know the other storm ponds throughout the City, do you have to come up here when you're going to start cleaning out, just for the maintenance and cleaning of those or just when you alter the wetland? Haak: Yes. There, that's a really good question and a lot of people, even in my position struggle with that. There are generally two kinds of storm water ponds in the city. There are the ones that were constructed in upland areas, in areas that were not wetlands. Have never been wetlands and only start to take on wetland characteristics when you excavate them. Those you basically can go in whenever you need to either make those bigger, as long as you're not impacting any additional wetlands, or just clean out the sediment. For those that were constructed, like these were, at least some of these were, actually all of these were constructed in wetlands already, and those when you make them bigger or you know extend the wetland impact, then you need to come and get all the appropriate approvals and get the technical folks from all the agencies to sign off on that as well so, it's just that second group that would need planning commission and city council approval. Undestad: Okay. Sacchet: Question Debbie? Larson: Well yeah. Just getting back to the pond that we have dug out, and I think we probably addressed this at another meeting but I'll bring it up again. How often do we go in and do maintenance on these ponds, especially ones within the city? And then I was noticing the one by Market Street, the smaller portion where the little, what do you call it, a bridge or, it seems like it's deeper on that end. So that's why you, but it will fill up at some point and that's when you have to go and dig it out again. Haak: That's correct. Larson: So when you get to that point is there another impact? Haak: No, the Wetland Conservation Act and the city allow for the maintenance... ponds for sediment removal because actually those affect the function and the value of that wetland. If you have let's say a very nice wetland and for some reason you've got a pipe going there that leads from a major road, if you've got a lot of sand and things like that that are spread on that road, they run off into that wetland. It's the activity of removing that deposited sediment from that wetland is exempt from the rules. So that's something that is anticipated by that Act. With regards to the city, we have about 400 storm water ponds in the city and we've recently completed an inventory of those and actually the State of Minnesota and the Environmental Protection Agency have recently, in 2003 was when the state law was, or rule was passed, that. Actually it wasn't a rule. It was a permit that was issued and that was done in 2003 that requires the inspection of all storm water infrastructure pipes and catch basins and storm water ponds on a 5 year basis. So we'll have to do, at least inspect 20% of our storm water ponds every year from now on. Now that we know where they are. Larson: So that's new? 7 0 0 Planning Commission Meeting — March 21, 2006 Haak: Exactly, yes. And actually the Planning Commission will be seeing our Surface Water Management Plan at the April 0 meeting. And actually holding a public hearing on that, and it's part of that and I'll go into greater detail then, but typically also to get to another question you asked was, the maintenance cycle for a storm water pond is anywhere from 10 to 20 years, depending on how much primarily again it's sand. That pond receives. Larson: Based on the need mainly. Haak: Exactly. Larson: Ahight, thanks. Sacchet: Yes Jerry, go ahead. McDonald: I hate to keep asking questions about the water and the capacity but you said a couple things I just want to get clear. The purpose of these ponds is to take care of the water quality within Rice Lake and Riley Lake. It is not to mitigate flooding in those types of issues, so the driver for maintenance is the purpose of clearing up water so, we're not looking to keep a certain depth in there for capacity, for flood run off or any of those things? Haak: Well there is, and that gets into a little bit of the engineering and the stone water facilities and I'm not the engineer here so Alyson will jump in and correct me if I'm going astray, but generally in storm water pond designs the area below the normal water level is the water quality volume, and that's what we're increasing, or the watershed district is proposing to increase in this project. The area above that normal water level is the flood control volume, so really you can only gain significant strives by raising that level which would be the 100 year level of that pond. So you get the, it's called dead storage below the normal level and you get the live storage, or the flood storage above that normal water level. And because in this case we're excavating out below the normal water level, that's where we're getting our water quality benefit, because that water is still, and it stays in the pond for longer. McDonald: Okay, thanks for clarifying that. Haak: Does that make more sense? McDonald: Yep. Sacchet: Just one quick question Lori. You mentioned a concern with Lake Riley water quality. Can you say a little more specifics about that. What type of issues did we encounter that this would be a good counter measure for. Haak: Sure. Primarily the issue that we've seen are you know the typical lake issues. The high phosphorous levels. The high chlorophyll levels, which results or you know which is an indicator of increased algae or duck weed, things like that in the pond. Or in the lake, I'm sorry. And additionally it would be that decreased visibility or the secchi depth. So if you're out Planning Commission Meeting — March 21, 2006 boating on Lake Riley and happen to go to Lotus Lake, Lotus Lake may be a little bit more clear at certain times of the year and Lake Riley might get a little bit greener. A little bit more green a little faster. Those types of things. So those are all the primary indicators of that water quality and it just compromises the usefulness of that water body, both for recreational purposes as well as for habitat for the plants and animals that live there. Sacchet: Thank you Debbie. This is a public hearing so I'd like to invite any residents that would like to address this issue in front of us. Is there anybody here? If you want to come up to the podium. Kathy Slavics: Do we have to come up? Sacchet: You have to come up, sorry. And if you want to pull the microphone up a little bit so it points, and if you want to tell us your name and address for the record, we'd appreciate that. Kathy Slavics: My name is Kathy Slavics and I live on Dakota Lane which is, my back yard backs up to St. Hubert's which is on Rice Marsh Lake, and I am not familiar with a lot of what's proposing but I'm curious with 212 coming in, and with Rice Marsh Lake expanding towards 212, how much are we going to be losing of kind of our buffer with noise and all of that because it looks like it's going to be expanded quite a bit. Sacchet: Do you want to say something about that Lori? Haak: Sure. Actually they're on Dakota and. Basically the existing pond, if you look, the existing pond is right here. So the expansion is primarily to the south and east. There is a small area of existing trees here that is proposed to be removed. But there also is an existing open water area, if you're familiar, can see it from your home probably up here. So it's just, the scale on this is 1 equals 60, so it's extending approximately 120 feet further south than the edge of the open water. So when you look at the entire, I'll go back to this one. When you look at the entire area as a whole, this is where the edge of the existing open water is, and you know the proposal is to extend it a little bit further south. So it still won't nearly go out to the main part of Rice Marsh Lake. And again the area that will be removed is kind of right in here. Kathy Slavics: Okay. And just out of curiosity do you know where the easement is that needs to be done on somebody's property? Haak: Actually there isn't. This is the Jerome property. All of these four, 1, 2, 3, 4 are all city owned. This is the one that has an easement so that property owner has already signed the easement is my understanding or that's in negotiations so. Kathy Slavics: So basically all of this area, I'm right here on the cul-de-sac. I have 2 % acres that back up to St. Hubert's. None of that will be changing? I mean I don't have to worry about, because I know part of my property is on the other side of the trail. Haak: Right, no. The only thing would be that there will be access across that trail but they would... 0 `J Planning Commission Meeting — March 21, 2006 Kathy Slavics: Right, and we have a couple easements in our back yard right now so. Haak: Yep, and that will stay, access will remain into the open part. Kathy Slavics: Okay. And I wonder too, we had a ton flooding all along here where 101, you know towards 101 that I wonder if, I mean hopefully that ... because we lost a lot of our trails, and do you know if this is affecting the proposed trails as far as going all the way around the lake? Haak: Ah no. The, whatever parks and recreation trail system they have worked out, this would not affect that. The Park Director has reviewed all of these plans. Kathy Slavics: Okay good, thank you. Sacchet: Thank you. Anybody else would like to address, please come forward and if you let us know your name and address. And pull the microphone towards you please. Bob Myers: Bob Myers, 8131 Dakota Lane. Could we put up the map or the, by Dakota Lane. Haak: Sure. Bob Myers: Currently these lots run into where the proposed pond to be expanded, is that correct? These are the corners of the lots. Haak: That's something we'll have to check into. Again this is a watershed district project and I assume that there were no impacts to private properties unless those lot lines. Bob Myers: I am the original owner of the land. I very well know where my property line is and these are the corners of my property. These are my neighbor's properties, and they are all impacted. Haak: We would need to check on that and determine whether or not there are drainage and utility easements existing or if in fact there, those property comers are appropriately shown. That's something again that I was not aware that, if that is indeed the case, we'll take a look at that. Sacchet: So what you're stating is that according to your knowledge some of this ponding would touch onto individual's properties. Bob Myers: Very much so. Sacchet: Okay. Bob Myers: Yes, the property lines, property actually now extends past where the existing pond is and into a private pond. 10 a Planning Commission Meeting — March 21, 2006 Sacchet: Yeah, that's definitely something that we need to look into. Bob Myers: It's actually shown on the map. So the map is drawn correctly, but the property lines on there. Haak: That's news to me. We'll check into that. Sacchet: We'll have to look into it. Thank you for bringing that to our attention. Bob Myers: Well my next question is then, there's property line markers for these lots and I'm wondering how those would be affected. Haak: Well that would, I'm sorry. Sacchet: Go ahead. Haak: If I may. That would depend on whether or not that is indeed the case. If that's the case then we would have to work with, or the watershed district would have to come up with a proposal for that so that would need to be addressed as a part of that, and you know certainly again if it's on your property they would need to communicate with you regarding that so, we'll look into that. Bob Myers: Alright, my next question is when is the start and finish of the construction. Haak: For these ... we're looking at winter construction because it minimizes the amount of impact to the rest of the water resource. Some of the others are waiting ... this construction season but again the property owners adjacent to these would be noticed prior to that construction. I believe, I forget exactly how we worded the condition. I think yes, at least 2 weeks prior to the beginning of work is what is recommended. Bob Myers: So most likely it won't be until next winter? Haak: For these along Rice Marsh Lake, that's correct. That's my understanding. Bob Myers: Okay. And my last question is that, will the property taxes of the people adjacent to the pond, are they affected in any way? Sacchet: Pond proximity tax. Do we have such a thing? Aanenson: Yeah, I'll speak to that issue. No, there's no assessments. No, the watershed district's paying for these projects with the city paying a small portion. Bob Myers: Okay, thank you. 0 Planning Commission Meeting — March 21, 2006 Sacchet: Thank you. Appreciate it. Anybody else would like to speak to this item? This is your chance to come forward. Seeing nobody else getting up, I will close the public hearing and bring it back to the commission. Lori, did I understand Alyson is actually going to look at this. Haak: Yes she is. Sacchet: What you propose, I mean this is pretty significant information that was potentially impacting this, isn't it? Haak: It is. Sacchet: So what would we do if this is the case? Aanenson: Well they would have to have permission to approve that pond. If that pond is on private property, they would have to get permission for that so. So it looks like we need some clarification. I think that can be resolved through a condition that appropriate easements are secured and access to property if there is an issue. Sacchet: We can add a condition to that effect. Aanenson: Correct. That's what I would recommend, yep. Yep, and then the watershed district also communicate to those property owners showing them where that property line is. Sacchet: Okay. Do we have any wisdom to share ladies? Aanenson: I still think it'd be a good condition to put in regardless. Sacchet: Did you want to say anything to this still Lori? Haak: Yes if I might. We have pulled the plat from the Hidden Valley subdivision, which. Aanenson: Can you zoom in on that Nann? Pull it towards you a little bit Lori and down. Haak: It's hard to see. I believe these are the lots in question through here. There is a utility easement for sanitary sewer that runs through the rear of those yards. In addition there's a utility and drainage easement that goes up to the southern edge of that area, so when this subdivision was platted, there was accommodation made for drainage and utility related improvements in these areas. That's why the city gets these easements is so that we can manage water in these areas. That being said, there is a public right to ponding or utilities within those area. That doesn't minimize the fact that it really is in the presence of the city, and especially when we do city projects, again this is not a city project, to work closely with the property owners so they know what to expect on their property because even though we do have the easement, there are property rights that are not conveyed with that easement. So that's the additional information that we can provide you. 12 0 0 Planning Commission Meeting — March 21, 2006 Sacchet: Can you point out on this plat where actually the pond is going to be. Where the current one is and how it expands. Just approximately. I think that'd be interesting for us. Also for the residents here. Over on the right edge. Haak: It's right in, the existing pond is right in here. The proposed pond is down through here. Sacchet: Okay. McDonald: So the pond really doesn't expand that much to the north. The expansion and everything is more to the south. Haak: That's correct. Actually, it's kind of interesting. As I look at this in more detail, again this is new to me so you'll have to excuse me here. The edge of the trail is at a certain elevation and actually the first let's say 20 feet south of the trail will remain the same. There will be excavation beginning approximately 20 feet from that south edge of the trail. So these lines here are the proposed contours and actually this is the middle of the existing open water it appears. So, and again you can't see those on the monitors or on television but here I can see that the contours that are existing, the deepest part is out here which is basically where that northern slope would begin being graded. So yes, the extension of the pond would really be south of where that existing open water is. Sacchet: Okay. Thank you. Haak: You're welcome. Sacchet: So we had a public hearing. We're discussing. Any comments or questions? Do we, ready for a motion? Keefe: I'll make a motion. The Planning Commission recommends the City Council approve Wetland Alteration Permit 06-06 subject to the following conditions 1 through 14. 14 being all appropriate permissions and easements must be obtained prior to the undertaking of any construction. Sacchet: Okay. We have a motion. Is there a second? McDonald: Second. Sacchet: Any further comments? Friendly amendments? No? Keefe moved, McDonald seconded that the Planning Commission recommends that the City Council approve Wetland Alteration Permit #06-06, subject to the following conditions: Wetland replacement shall occur in a manner consistent with the Minnesota Wetland Conservation Act (MR 8420) at a ratio of 2:1. 13 0 0 Planning Commission Meeting — March 21, 2006 2. The applicant shall notify nearby property owners of the proposed project at least two weeks prior to beginning work. The notice shall, at a minimum, provide a summary of the purpose of the project, the timeline for project completion, and contact information for someone with RPBCWD who is able to provide more information about the project. It is recommended that the applicant work with the City to identify property owners receiving notice and to provide a link to a project website from the City's website. The applicant shall restore any disturbed areas and restore or replace any damage to infrastructure on City property. 4. All exposed soils from temporary haul routes, exposed slopes above the normal water level (NWL) and adjacent areas to the project shall be temporarily stabilized and seeded within the 7, 14, 21 day time frames depending upon slopes.

McDonald: You mentioned about diversity and the way we're building all of this and one of the things that I guess we've had this discussion before but these things keep kind of coming at us piecemeal and then it's difficult to put them into the context of the overall plan. At one time that area down there, we were looking at more commercial development for tax purposes, and what I'm seeing now by looking at this, this is becoming pretty much residential and how does that impact you know our comprehensive plan and what we're looking for. Aanenson: Good question. This property over here would like to go more commercial. Probably do new urbanism, mixed use project. And this piece over here is still guided industrial. So this piece would switch, it's guided low or medium, so they're contemplating a switch to a different land use. McDonald: As far as the overall stock then of what we have available for development, you feel that we're still okay as far as what we set aside for commercial? The possibility here for commercial development. 15 A" Metropolitan Council March 20, 2006 Ms. Lori Haak City of Chanhassen 7700 Market Boulevard Chanhassen, MN 55317 RE: MCES MH casting Adjustment and Encroachment MCES Interceptor 8253-329, MH 62 Riley -Purgatory -Bluff Creek Watershed District, Chanhassen Dear Ms. Haak: Environmental Services RECEIVED MAR 2 3 2006 CITY OF CHANHASSEN The Metropolitan Council Environmental Services (MCES) has reviewed the connection permit you submitted regarding the above referenced project. A permit is not necessary for projects with only MH casting adjustments, but it has been helpful in this review. The plan sheet with details dated March 17, 2006 was reviewed for potential impacts to the regional disposal system. The plans depict a new gravel maintenance road to the east of MH 62. It appears that during your survey of the area, it was discovered that MH 62 was buried 8" below the existing grade. The proposed grade is approximately 4" higher. Your project will be raising the MH up to the proposed grade with a total adjustment of 12". We have reviewed the proposed adjustment and have no objection to it. Enclosed is MCES record plan sheet number 27, for the interceptor facility which depicts the MH structure. The plan also shows the removal of three 18" CMP culverts to be replaced by a new realigned 48" CPEP. There will be new riprap placed on MCES property. This encroachment was reviewed and was determined to be acceptable. A "Consent to Allow Encroachment Onto Sanitary Sewer Agreement' will not be necessary. It is required that the contractor contact Mr. Adam Winiarczyk at telephone number (651) 6024025 (7:30a.m. to 4:00p.m.) and make arrangements to have an inspector on site after the adjustment is made but prior to backfilling. A minimum 48-hour notice should be given. Please refer to this letter when requesting an inspection. If the MCES inspector is not notified prior to the backfrlling of the MH structure after the completion of the adjustment, the contractor/city will be required to pay all costs associated with re -excavation and inspection.

The City of Eden Prairie submitted a similar petition concurrently. Several of the ponds will be constructed in conjunction with Trunk Highway 212 or future development. The remaining ponds are proposed to be part of this project, or have been eliminated due to the redesign of downstream facilities. In May 2005, a wetland delineation was completed by Barr Engineering. On June 23, 2005, City staff verified the delineated wetland boundaries. On July 28, 2005, City staff approved the wetland delineation for the areas where work will occur in conjunction with the proposed project. Two of the proposed ponds are within wetlands adjacent to Rice Marsh Lake. The Ordinary High Water Level (OHW) of Rice Marsh Lake is 877.0. Any wetland impacts occurring below the OHW require permits from the Minnesota Department of Natural Resources (DNR). WETLANDS Existing Wetlands Five wetland basins are proposed to be impacted within the project area. Basin RM-1.1 is located just south and west of Rice Marsh Lake Park. It is a Type 4/3/1 wetland adjacent to Rice Marsh Lake (DNR Protected Water 10-1P). The basin is dominated by reed canary grass, sandbar willow, cattail, black willow and box elder. Basin RM-2.1 is located adjacent to the railroad tracks, just north of Lotus Iawn and Garden. It is a Type 4 wetland dominated by open water and fowl bluegrass. Basin RM-2.5 is located just west of the Chanhassen/Eden Prairie border along a small ravine. It is a Type 4/6 wetland dominated by reed canary grass, box elder, red -osier dogwood, buckthorn, aspen and black willow. Basin RM-2.6 is located just south of Basin RM-2.5 adjacent to Rice Marsh Lake (DNR Protected Water 10-1P). It is a Type 4/2/3/6 wetland dominated by reed canary grass, Canada watermeal, sandbar willow and black willow. Basin RM-6.5 is located in the northwest quarter of Market Boulevard and Trunk Highway 101. It is a Type 4/3/2/6 wetland dominated by cattail, pondweed, reed canary grass, willow, red -osier dogwood and cottonwood. Planning Commission Planning Case No. 06-06 March 21, 2006 Page 3 of 6 Wetland Impacts The proposed project proposes fill and excavation within all five wetland basins within the project area. Proposed wetland impacts are as follows: Basin Fill Excavation (Type 3,4 or 5) Excavation (Not Type 3, 4 or 5) 1.1 725 795 20,074 2.1 298 22,648 0 2.5 1,456 0 2,090 2.6 7,333 0 31,856 6.5 780 19,728 35,167 Total 10,592 43,171 89,187 The total amount of impact proposed by the project is 142,950 square feet (3.28 acres). Wetland Mitigation Wetland replacement is required at a 2 to 1 ratio (6.56 acres). The replacement of wetland will be accomplished through the withdrawal of wetland credits from the Minnesota State Wetland Bank. ANALYSIS Initially, additional ponding sites were considered for this project. However, as the RPBCWD analyzed the sites, several sites were found to be unnecessary if existing downstream ponds were enlarged. By taking a more comprehensive regional ponding approach, the smaller ponds were eliminated. This reduced the cost of the project due to easement acquisition and site access difficulties. In addition, it will likely increase the effectiveness of the ponding while increasing the efficiency of future pond maintenance. The RPBCWD has not yet notified property owners near the proposed pond improvement projects of the work that will be done. The applicant must notify nearby property owners of the proposed project at least two weeks prior to beginning work. The notice should, at a minimum, provide a summary of the purpose of the project, the timeline for project completion, and contact information for someone with RPBCWD who is able to provide more information about the project. It is recommended that the applicant work with the City to identify property owners receiving notice and to provide a link to a project website from the City's website. The proposed project is dependent on access onto and across City property. The applicant should restore any disturbed areas and restore or replace any damage to infrastructure. Erosion Control All exposed soils from temporary haul routes, exposed slopes above the normal water level (NWQ and adjacent areas to the project must be temporarily stabilized and seeded within the 7, 14, 21 day time frames depending upon slopes. Any concentrated flow areas must receive temporary protection within 24 hours of connection to surface waters. Erosion control blanket Planning Commission Planning Case No. 06-06 March 21, 2006 Page 4 of 6 should be used in concentrated flow areas and for slopes of 3:1. All remaining areas shall be mulched and seeded to control erosion. The applicant should provide information regarding the fate of the excavated/excess material, as well as the stabilization and/or containment of the material. Temporary energy dissipation should be installed at existing flared end sections to the bottom of the basin at the end of each day to protect against erosion. This could include temporary plastic sheeting or geotextile fabric secured to the soil. Sediment Control All existing outlets/proposed outlet structures should be temporary riser structures until the ponds and adjacent areas are stable. During excavation and work in the spring, rains may cause re -suspension of solids within the ponds. A temporary riser will ensure minimal sediment discharge will be possible. Street sweeping and scraping will be needed daily (potentially more often) during active haul times. A dedicated site pickup sweeper may be needed. Runoff Control/Dewaterin¢ The applicant should provide details as to how dewatering will be accomplished for the basins in this project. A temporary standpipe and rock cone could be used to draw down the ponds, or a floating skimmer pump could be used. Initially the drawdown of the ponds will likely not be an issue. If it rains and re -suspension of sediment occurs the water will have to sit in the pond until it is clear enough to discharge to receiving waters. A standpipe and rock cone with the pump drawing water from the pipe would help minimize the lag time after a storm to begin drawing the ponds down again. The applicant should have a flocculent available on the project to facilitate sediment removal from sediment -laden water. Energy dissipation should be provided at all discharge points from dewatering pumps. Waters receiving dewatering discharges should be large enough to handle the volume and velocity of the water. Other A encies The applicant shall apply for and obtain permits from the appropriate regulatory agencies (e.g., Minnesota Pollution Control Agency (NPDES Phase H Construction Permit), Minnesota Department of Natural Resources (for dewatering; impacts below the OHW of Rice Marsh Lake), Minnesota Department of Transportation) and comply with their conditions of approval. Planning Commission Planning Case No. 06-06 March 21, 2006 Page 5 of 6 FINANCING The cost of the improvements will be divided between the RPBCWD and the City. The City will be responsible for 75% of the costs for easement acquisition. RPBCWD will pay all other costs. The engineer's estimate for the construction of the 5 ponds is approximately $1,100,000. One easement will be necessary to complete this project. All other improvements are on City property. The total cost for easement acquisition is $15,000; the City's portion of the costs is 75% of that, or approximately $11,250. The City's portion of the improvement costs will be paid through the Surface Water Management Fund's Capital Improvement Program Property Acquisition item (SWMP-014). In 2006, $200,000 was allocated for the acquisition of property in accordance with the City's Comprehensive and Surface Water Management Plans. RECOMMENDATION Staff recommends the Planning Commission adopt the following motion: "ne Planning Commission recommends the City Council approve Wetland Alteration Permit 06-06 subject to the following conditions: 1. Wetland replacement shall occur in a manner consistent with the Minnesota Wetland Conservation Act (MR 8420) at a ratio of 2:1. 2. The applicant shall notify nearby property owners of the proposed project at least two weeks prior to beginning work. The notice shall, at a minimum, provide a summary of the purpose of the project, the timeline for project completion, and contact information for someone with RPBCWD who is able to provide more information about the project. It is recommended that the applicant work with the City to identify property owners receiving notice and to provide a link to a project website from the City's website. 3.

Approximate UTM coordinates for this area are Northing 458539, Easting 4966920. Approximate Decimal Degree coordinates for this area are Latitude 44.854488, Longitude-93.524720. The project area includes five work sites: one in Eden Prairie and Chanhassen and four others entirely in Chanhassen. See the attached maps and drawings for more information on the project location and features. Figures 1 and 2, attachments 2006-89-JJY, 4 of 10 and 5 of 10, show the location of the overall project area, Rice Marsh Lake and Lake Riley, and the five major work sites. DESCRIPTION OF PROJECT: In cooperation with the Cities of Chanhassen and Eden Prairie, the Riley -Purgatory -Bluff Creek Watershed District proposes to expand and improve existing storm water management basins and conveyance systems in Chanhassen and Eden Prairie. Although the project would alter 8.32 acres (fill in 0.35 acre and excavation and grading in 7.97 acres) of existing wetland, the affected wetland area is currently receiving untreated storm water. Most of this wetland has been altered to function as storm water management basins, and it has received storm water and sediment for CEMVP-OP-R (2006-89-JJY) SUBJECT: Notice of Application for Permit to Discharge Dredged and Fill Material a number of years. Not all of the area filled would be converted to upland. Compensatory mitigation measures (see below) are also part of the proposed project. Recent studies and computer modeling done for the applicant indicate that existing storm water management basins within the waters of Lake Riley and Rice Marsh Lake are inadequate to meet water quality management goals of the Watershed District. According to the applicant, both lakes currently do not meet desired water quality standards (see table 1, attachment 2006-89-JJY, 1 of 10). Although the current total phosphorus concentrations in Rice Marsh Lake and Riley Lake are lower now than when Rice Marsh Lake received effluent from two wastewater treatment plants, the lake sediments are still rich in phosphorus, particularly in Rice Marsh Lake. Ongoing and recent development is likely to contribute additional phosphorus and other pollutants to the lakes. During periods of summer anoxia (low oxygen) and greater runoff, Rice Marsh Lake contributes more phosphorus downstream in the watershed, to Riley Creek and Lake Riley. During dry years, the water quality of Lake Riley tends to decline. Consequently, the water quality of these lakes may decline unless remedial measures are taken. The current project is intended to improve the quality of the runoff going into each of these lakes. Based on its studies, the applicant believes that the most feasible, structural, best management practice to meet the water quality goals of the Watershed District and the two cities is to improve and expand existing storm water basins. This project includes five proposed improvements in existing wetlands that have been previously altered (excavated and connected to storm water outfalls or ditches) to serve as storm water management and water quality basins (see enclosed plans, attachments 2006-89-JJY, 4 of 10 through 10 of 10): 1. Upgrade an existing storm water management/water quality basin (identified as basin RM-1.1, occupying part of a 3.9-acre wetland) on the northwest side of Rice Marsh Lake, within Rice Marsh Lake Park, south of Dakota Lane (drawing W-01, attachment 2006-89-JJY, 6 of 10). This basin is a modified wetland that receives untreated storm water and is hydraulically linked to Rice Marsh Lake. It is a marsh with a forested, seasonally flooded fringe. (Fill impacts are 0.118 acre; excavation/grading impacts are 2.655 acres.) 2. Upgrade an existing storm water management/water quality basin (RM-2.2, a 1.8-acre wetland) on the north side of 78t' Street West, south of Twilight Trail, and west of 187`h Avenue (drawing W-02, attachment 2006-89-JJY, 7 of 10). This basin presently receives untreated storm water. It is a marsh and shrub can•. (Fill impacts are 0.007 acre; excavation impacts are 0.518 acre.) 3. Upgrade an existing storm water management/water quality basin (RM-2.5, a 0.08-acre wetland) on the north side of Rice Marsh Lake, located within Rice Marsh Lake Park, southwest of Poplar Circle and southeast of Cheyenne Avenue (drawing W-03, attachment 2006-89-JJY, 8 of 10). This basin receives untreated storm water and is hydraulically linked to Rice Marsh Lake. It is a marsh and shrub carr. (Fill impacts are 0.033 acre; excavation impacts are 0.073 acre.) 4. Upgrade an existing storm water management/water quality basin (RM-2.6, occupying part of a 3.5- acre wetland) on the north side of Rice Marsh Lake, located within Rice Marsh Lake Park, downstream of basin RM-2.5, southwest of Poplar Circle and southeast of Cheyenne Avenue (drawing W-04, attachment 2006-89-JJY, 9 of 10). This basin receives untreated storm water and is hydraulically CEMVP-OP-R (2006-89-JJY) SUBJECT: Notice of Application for Permit to Discharge Dredged and Fill Material linked to Rice Marsh Lake. It is a marsh and shrub carr. (Fill impacts are 0.164 acre; excavation impacts are 1.425 acres.) 5. Upgrade an existing storm water management/water quality basin (RM-6.5, a 3.4-acre wetland) northwest of the intersection of Trunk Highway 5 and Market Boulevard (drawing W-05, attachment 2006-89-JJY, 10 of 10). This basin receives untreated storm water. It is a marsh and shrub carr. (Fill impacts are 0.298 acre; excavation impacts are 3.269 acres.) Because the affected wetlands have received sediment for a number of years, the character of the wetlands has changed so that they have less open water and more emergent and woody plants. TOTAL AREA OF FILL/DREDGING: The total area directly affected by fill, excavation/grading, and redeposition of dredged material includes 8.32 acres (362,384 square feet) of wetland. This impact includes fill in 0.35 acre (15,460 square feet) of wetland, including riprap and temporary fills, plus excavation, grading, and shaping that may involve discharges of dredged material in 7.97 acres (143,388 square feet) of wetland. See table 2, attachment 2006-89-JJY, 2 of 10, for a summary of the proposed impacts. PROPOSED MITIGATION: Some of the affected area is wetland that has been degraded by construction of previous storm water ponds and discharges of untreated storm water. These wetlands would be altered to increase their storm water management functions and wildlife habitat values. Almost all of the affected wetland would remain wetland, although more of it would be shallow open - water wetland with emergent fringes, compared to the existing condition. Approximately 6.79 acres of storm water wetland would be planted and improved in five locations as part of this project. The applicant hopes to receive partial mitigation credit for this work. Following preliminary discussions with the Corps of Engineers, the applicant proposed the - compensatory mitigation summarized in table 3, attachment 2006-89-JJY, 3 of 10. The proposed mitigation includes plantings and other enhancements in 6.79 acres (295,419 square feet) of the excavated areas (including expansion of the existing storm water pond wetlands) and purchase of 5.95 acres of existing wet meadow and marsh credits from the Mueller Wetland Bank in Sibley County. The Corps of Engineers is studying the need for mitigation for the project impacts and will make the final determination on the need for mitigation. If the project is permitted, the permit may include measures to limit the drainage and/or to mitigate for any lost wetland area, functions, and values. VEGETATION IN AFFECTED AREA: The majority of the directly affected area is dominated by reed canary grass, cattail, black willow, shrub willows, and box elder. Some buckthorn is in at least one of the wetlands. Part of the affected area is open water with pondweeds and duckweed dominant. These species indicate that the affected wetlands exhibit relatively limited species diversity and that they have been disturbed and are now dominated by invasive and opportunistic species. SOURCE OF FILL MATERIAL: A relatively limited amount of fill is needed for this project. Fill material may be primarily material excavated on site or obtained at an off -site borrow area. If a new borrow area is opened for this site, it may require an archaeological survey. CEMVP-OP-R (2006-89-JJY) SUBJECT: Notice of Application for Permit to Discharge Dredged and Fill Material SURROUNDING LAND USE: Until relatively recently, much of the surrounding land use was predominantly agricultural, although the adjacent areas are now largely developed as residential and commercial. These developments contribute runoff to the Riley Creek watershed. POTENTIALLY TOXIC MATERIALS THAT COULD BE USED AT THE PROJECT SITE: No toxic materials are expected to be used at the site as part of the proposed project. PRECAUTIONS TO PROTECT WATER QUALITY: The project itself is intended to improve downstream water quality by removing phosphorus and other pollutants from the water discharged into Rice Marsh Lake, Lake Riley, and Riley Creek. During and after construction, silt fences, erosion control blankets, and plantings would be used to minimize erosion and sedimentation. 3. REPLIES/COMMENTS.

JURISDICTION. This project comes under the regulatory jurisdiction of the Corps of Engineers because Riley Creek is a tributary to the Minnesota River, a navigable water of the United States. REGULATORY AUTHORITY: This application will be reviewed according to the provisions of Section 404 of the Clean Water Act. Therefore, our public interest review will consider the guidelines set forth under Section 404(b) of the Clean Water Act (40 Code of Federal Regulations 230). THE APPLICANT HAS STATED THAT THE FOLLOWING STATE, COUNTY, AND/OR LOCAL PERMITS HAVE BEEN APPLIED FOR/ISSUED: Minnesota Department of Natural Resources Minnesota Pollution Control Agency Riley -Purgatory -Bluff Creek Watershed District City of Chanhassen City of Eden Prairie 6. STATE SECTION 401 WATER QUALITY CERTIFICATION. Valid Section 404 permits cannot be issued for any activity unless state water quality certification for the activity is granted or waived pursuant to Section 401 of the Clean Water Act. The state Section 401 authority in Minnesota is the Minnesota Pollution Control Agency (MPCA). The St. Paul District has provided this public notice and a copy of the applicant's Section 404 permit application form to the MPCA. If MPCA needs any additional information for the Section 401 application to be considered complete by MPCA, the MPCA has indicated that it will request such information from the applicant. It is the permit applicant's responsibility to ensure that the MPCA has received a valid, complete application for state Section 401 certification and to obtain a final Section 401 action from the MPCA. The MPCA has indicated that this public notice serves as its public notice of the application for Section 401 water quality certification under Minnesota Rules Part 7001. The MPCA has also indicated that the Section 401 process shall begin to commence upon the issuance date of this public notice unless the MPCA notifies both the St. Paul District and the permit applicant to the contrary, in writing, before the expiration date of this public notice. The MPCA has eliminated the staffing resources for the Section 401 certification program due to budgetary limitations. Due to staff reductions, MPCA intends to waive many Section 401 certification applications, with limited exceptions, but the MPCA reserves the right and authority to proceed differently if extreme or unique circumstances merit a different approach. In many cases, the waiver of Section 401 certification means that the MPCA has not reviewed federally permitted projects in detail for conformance with state water quality standards and that the MPCA has not made a determination of the proposal's compliance with state water quality standards. This waiver action, however, will not exempt the applicant from the responsibility of complying with all applicable water quality standards and requirements as contained in Minn. R. Ch. 7050 and all other applicable state rules regarding water quality. The applicant will need to make a self-determination of water quality compliance of their CEMVP-OP-R (2006-89-JJY) SUBJECT: Notice of Application for Permit to Discharge Dredged and Fill Material proposal. In the event of water quality violations caused by the applicant's project, enforcement action may be taken by the MPCA. Any comments relative to MPCA's intention to waive Section 401 certification for the activity proposed in this public notice may be sent to the following address: Minnesota Pollution Control Agency Regional Environmental Management Division Attention: Section 401 Certification 520 Lafayette Road, North St. Paul, Minnesota 551554194 7. HISTORICAL/ARCHAEOLOGICAL. This public notice is being sent to the National Park Service, the State Archaeologist, and the State Historic Preservation Officer to determine if any known cultural resources may be affected by the described work. Any unknown archaeological, scientific, or historical data could be lost or destroyed by the work described in the permit application. However, the latest version of the National Register of Historic Places has been consulted, and no listed properties (known to be eligible for inclusion, or included in the Register) are in the project area. 8. PUBLIC HEARING REQUESTS. Any person may request, in writing, within the comment period specified in this notice, that a public hearing be held to consider this application. Requests for public hearings shall state, in detail, the reasons for holding a public hearing. A request may be denied if substantive reasons for holding a hearing are not provided or if there is otherwise no valid interest to be served. 9. PUBLIC INTEREST REVIEW.

Have you been able to find the past development plans or any other information, which may give us a better idea if the following, proposed new/altered water quality pond locations, indicated below may have been historic wetlands? 2.1, 2.4, 2.8, and 6.9. Can you draft a letter indicating your decision concerning the wetland delineations you reviewed on June 23rd? Thanks!

I wouldn't be adverse to 6 am if we're not trampling through people's yards. Let me know.
