Fax: 952.227.1404 Additionally, there was some question as to quality of the trees in the areas that would be removed Staff met with Alan Olson, Regional Forester for the DNR, to discuss this question. Mr. Olson made a site inspection on September 10, 2004. His assessment of the site was one of remnant, Big Woods forest in good condition with little rot and a large number of hardwood trees in the 30 -inch size class. He specifically noted the northwestern forested area as being of high- quality, large diameter sugar maple and basswood trees. According to the plans, The City of Chanhassen • A growing community with clean lakes, quality schools, a charming downtown, thriving businesses, winding trails, and beautiful parks. A great place to live, work, and play. Staff has since reviewed the existing topography of TH 212 adjacent to the site. It Planning 8 Natural Resources appears that there is a low point in TH 212, approximately one-half mile east of pPe p pP y Phone: 952.227.1130 the site, at an elevation of 710. This low point is west of Dell Road, which is the Fax: 952.227 1110 closest intersecting street east of the site. The elevation of TH 212 west of the site only drops to an elevation of 722, which means that TH 212 would flood on the Public works 1591 Park Road east side of the site before flooding on the west. The road flooding east of the site Phone: 952.227.1300 would prevent any vehicular movement to Dell Road but residents could still Fax: 952.227.1310 travel to/from the site from the western side via TH 101 north. Senior Center Phone: 952 227,1125 Staff has also reviewed the comments from the Lower Minnesota River Fax 952227.1110 Watershed District. Based on this review, staff is recommending the addition of Web Site condition 32: "The applicant's engineer must work with City staff to revise the www.ci chanhasseo.maus drainage calculations per City standards and NURP requirements."

The wooded area within the grading limits had a greater mix of species and more size classes, i.e., had a greater range of diameters. While this area is of good quality, it is not of the caliber of the northwestern area. Mr. Olson suggested that the developer look at harvesting the trees within the grading limits. Based on this comment, staff is recommending the addition of condition 31: "The harvesting of timber shall be limited to the area within the grading limits."

LEVEL OF CITY DISCRETION IN DECISION-MAKING: The City has limited discretion in approving or denying interim use permits, based on whether or not the proposal meets the conditional use permit standards outlined in the Zoning Ordinance. If the City finds that all the applicable conditional use permit standards are met, the permit must be approved. This is a quasi-judicial decision. Location Map Moon Valley Gravel Mine Restoration Interim Use Permit City of Chanhassen Planning Case No. 04-27 6 %owTy F f 3 Subject Site c dDm I G I S � I � I i I I i I I i Moon Valley Gravel Mine IUP Planning Case No. 04-27 August 17, 2004 Page 2 PROPOSAUSUMMARY The applicant is requesting an interim use permit to permit the excavation, grading, and restoration of the existing mining pit and a future development area west of the mining pit. Interim use permits are processed in the same manner as conditional use pernits. The operation will require the removal of approximatelyl.8 million cubic yards of material from the site. The project site is adjacent to the Richard T. Anderson Conservation Area in Eden Prairie. To the south across Highway 212 are the Minnesota Valley Wildlife Refuge and the Minnesota River. To the north are the Hennepin County Regional Trail and the Settlers West subdivision. Access to the site is proposed via Highway 212 (Flying Cloud Drive). The proposed site grading and slope restoration will prepare the site for future development when urban services are available, stabilize the site to reduce run-off and erosion, and permit the vegetation, especially the trees, to grow between now and the time the site is developed. The previous approved site grading plan would have graded the site out to Highway 212, created a usable development area of 8.5 acres and altered bluff area in both the northwest and southwest comers of the property. In an effort to try and preserve more of the mature trees on the site, staff is recommending that the grading on the eastern side of the creek end at the proposed high -point elevation in the usable area of 756. With the exception of the bluff area, this area could be included in the calculation of developable area at the time of development review. In addition to the mining operation, the site has been used as a rifle -range. Due to the mining use of the property, the fact that materials have been brought in to the site and the potential problems from lead in the soil from the gun range operation, staff is recommending that a Phase I Environmental Audit be performed on the property. Staff is recommending approval of the interim use permit subject to the recommended conditions of approval. APPLICABLE REGULATIONS Chapter 7, Article III. Excavating, Mining, Filling and Grading Sections 20-231 through 20-237, Conditional Use Permits BACKGROUND May 1990, the city adopts an ordinance requiring persons engaging in earthwork activities to obtain a permit. September 1990, Moon Valley initiates a lawsuit claiming that the City did not have the authority to require Moon Valley to obtain a permit. In April 1991, the court ruled that the City can require Moon Valley to obtain a permit. Moon Valley Gravel Mine IUP Planning Case No. 04-27 August 17, 2004 Page 3 June 22, 1992, the Chanhassen City Council approves an earth work permit for the mining operation. August 1993, the court upheld the 100 -foot setback requirement for mining operations to the property fine and addressed the establishment of a restoration fund. January 1994, the City Council further considers the earthwork permit in light of the court order from August 1993. February 1996, the City executes an earthwork permit agreement resolving the mining operation and restoration. DISCUSSION GRADING/DRAINAGE/EROSION CONTROL The applicant is requesting an interim use permit to excavate approximately 1.8 million cubic yards of material from the site. The goal of the grading is to restore the severe erosion areas on the site and to leave the site in a condition that will allow future multi -family housing to be developed. The applicant is proposing to grade down at steep, 40% (2.5:1) slopes from the high points on the north and south sides of the property. This will allow a relatively flat area with a gentle slope of 4% (25:1) to be developed in the center of the property. The flat area will be developed into multi -family housing sites when municipal sewer and water is extended to the area in the future. In addition, the severe rutting and erosion gullies that currently exist on the site will be restored. Permanent vegetation will be developed over all bare soil areas. Previously, a restoration plan for the main pit area east of the creek had been prepared in 1992 and approved by the city for this site. The 1992 plan proposed to grade approximately 3 acres of bluff area with 3.9 acres of tree removal. The current proposal has approximately 2.6 acres of bluff grading and 7.3 acres of tree removal. While the new plan does result in more tree loss, the impact to the bluff area is less than the previously approved plan. Also, the amount of usable or developable area has been increased from approximately 8.5 to 14 acres. In an effort to try and preserve more of the mature trees on the site, staff is recommending that the grading on the eastern side of the creek end at the proposed high -point elevation in the usable area of 756. This would preserve approximately 1.6 acres of additional tree canopy while decreasing the bluff impact from 2.6 to 2.4 acres. Terminating the grading at the high -point would more closely follow the natural drainage pattern in the area. It would also alleviate the need for additional storm sewer in the future in order to capture the drainage and route it back to Pond 2. The usable area available would still be 12.4 acres which is nearly four acres greater than the 1992 plan. The existing site generally drains from the north to the south. There is an existing creek/wetland which runs through the center of the site. Eventually, the entire site drains to the Minnesota River valley through existing culverts under TH 212. Under proposed conditions, the entire graded site area will drain to the two proposed ponds on either side of the creek which divides the site. Pond 1, on the west side of the creek, will outlet to the adjacent creek and Pond 2 will outlet to the TH 212 ditch. As in the existing state, the treated storm water will then drain to the Minnesota River valley under TH 212. Details for the proposed pond outlets should be Moon Valley Gravel Mine IUP Planning Case No. 04-27 August 17, 2004 Page 4 submitted for review by the City. Each of the proposed ponds has been designed to NURP standards and sized for the future developed state of the site. The submitted drainage calculations show that the existing 10- and 100 -year runoff rates are being met, per City Code. On-site ponding should be adjusted, if necessary, at the time of site development to meet the City's requirements for proposed build -out conditions. In the future, when a development proposal is submitted, drainage and utility easements over the ponds and creek will be required. Erosion control has been shown on the plan in accordance with the City's Best Management Practices Handbook (BMPH). Staff would recommend additional Type 1 silt fence in the southeast comer of the site around the grading limits and around the proposed pond outlet apron. All disturbed areas as a result of construction are required to be reseeded and mulched within two weeks of site grading. If erosion control measures installed in conjunction with this interim use permit are deemed by the City to be ineffective, the City will inform the applicant in writing of any deficiencies. The applicant will be required to remedy the deficiencies prior to site development. The required remedy(ies) may include, but are not limited to: increased frequency of plantings, additional erosion control blanket, or terracing of the northernmost slope to permanently break up the length of the slope. Phasing is a very important management tool for erosion control. Stabilization of the toe (first 150 feet of the slope) is needed immediately upon final grade. Stabilization should be done in phases. Large portions of the site should not be left exposed over weekends or during forecasted heavy rains. The slopes should be tracked with a dozer at all times. The dozer should be run perpendicular to the slope to track the slope. The northeast "corner" of the slope will be an area of instability because storm water will concentrate in the Swale and possibly form a gully. (This area is north of soil boring 18, south of soil boring 14 and in-between soil borings 10 and 15. ) A terrace, turf reinforcement mat and slope drain will likely be needed in this area to promote long term stability. Due to the steep slopes and long runs of the slope, straw fiber rolls may be needed to aid in stabilization of all the slopes with the MN DOT Category 3, 2S wood fiber blankets. The fiber rolls would help break up the length of slope and minimize erosion potential of the slope with the erosion control blankets. Six-inch fiber rolls are needed every 15 to 20 feet. Proper blanket application is crucial for this site. The blankets must make 100% contact with the soil and stapled according to manufactures specifications. The staple pattern is vital to proper blanket function. The blankets should be head trenched as well. Geotextile and riprap or geogrids or other approved stabilization is needed to provide toe protection; there is a chance the toe of the 2.5 to 1 may start head cutting without toe protection. The seed mix specified (MIN DOT 500) should be changed to MIN DOT Native mix 340 (Sandy Mid Height, dry conditions — i.e. south facing slope). An application rate of 16 pounds per acre is recommended (20 pounds per acre for hydoseeding or broadcasting). Depending on the final soil used, blanket application may be difficult. If the soil is too sandy, stapling the blanket over long runs will be futile. 'Terracing' blankets or using strips of blankets with a heavy application of the seed mix (20 pounds per acre) and hydromulch will be needed. Silt fence should be installed at least 25 feet away from the toe of the slope to provide storage and allow the silt fence to function properly. As stated on the plan, the temporary sediment Moon Valley Gravel Mine IUP Planning Case No. 04-27 August 17, 2004 Page 5 basins must be installed prior to grading activities. Berms may be needed to divert runoff into the basins along TH 212. Subsurface storm water movement should be considered with surface movement of storm water. When considering storm water management, installation of draintile at the toe should be considered to reduce any future possibility of sloughing due to saturation from ground water or slope seepage. It is currently unclear where the applicant will be hauling the excess material to. The grading is proposed to be a phased operation with the 15` phase beginning this fall. It is anticipated that the Ist phase will begin on the eastern edge of the site and will restore the slope coming down from the Settlers West development to the north. The applicant should be aware that if the excess material is transported to another site in Chanhassen, a separate grading permit will be required for the other property. Permitted hours of operation will be 7:00 a.m. to 6:00 p.m., Monday through Friday, and 9:00 a.m. to 5:00 p.m. on Saturday with no work permitted on Sunday or legal holidays. Staff has not yet received a proposed haul route as required. Staff is recommending that the applicant provide a proposed haul route for review and approval. In addition, appropriate signage for hauling along TH 212 will be required. Staff is recommending that the interim use permit expire five years from the date of approval from the City Council. Annually, a grading permit shall be required. The permit maybe renewed, however, on an annual basis subject to City staff review of conformance with the conditions of the interim use permit and approval of the annual permit. The applicant will need to request a formal extension 60 days prior to the expiration date. Financial security to guarantee restoration and erosion control measures will be required with the permit. The permit is also subject to administration fees. The administration fees are based on the number of cubic yards of material being graded. The fees are taken from the Uniform Building Code Appendix, Chapter 33. Based on 1.8 million cubic yards of material, the applicant must pay the City $7,124.00 prior to the City signing the permit. LANDSCAPING AND TREE PRESERVATION The applicant is proposing to remove 13 acres of trees off the site due to grading operations. The site currently has 34 acres of trees, much of them in bluff areas. Staff is proposing that grading at the western end of the mining area be stopped at the 956 contour. This would save approximately 1.4 acres of trees. These trees may later be removed for development, but do not appear to be a necessary item at this point. Tree removal calculations are not required for the site restoration since is it not a subdivision application. The calculations will be required at the time of site development. Restoration of the slopes will require seeding, fiber blankets and tree planting. The applicant has proposed wood fiber blankets for erosion control. Staff recommends that MNDOT Native Mix 340 be used for the seeding. This seed mix contains mid -height grasses recommended for sandy and/or dry areas. All restored slopes shall be planted with trees. The trees shall be bare -root, native species, one-half to one -inch in diameter, five to ten foot spacing in a random pattern from the top to the toe of the slope. The trees are to be planted closely assuming a 10-20% normal loss due to environmental conditions and stock vigor. The area to be planted is approximately Moon Valley Gravel Mine IUP Planning Case No. 04-27 August 17, 2004 Page 6 21.86 acres. The approximate number of trees needed is 9,531 to 38,080, depending on the spacing. Tree preservation fencing must be installed at the edge of grading limits. According to ordinance, when the site is developed for residential or office, none of the wooded areas on bluffs will be counted towards canopy coverage for the site. Additional plantings will be required at the time of site development. RECOMMENDATION Staff and the Planning Commission recommends that City Council adopt the following motion: "The Chanhassen City Council approves Interim Use Permit Planning Case #04-27 to permit grading, excavation and slope restoration as proposed on the plans prepared by Sathre-Bergquist, Inc., dated 7/16/04, subject to the following conditions: 1.

On August 17, 2004, the Chanhassen Planning Commission met at its regularly schedule meeting to consider the application of Beatrice Zwiers and Moon Valley Aggregates, Inc. for an interim use permit for the property located at 100 Flying Cloud Drive. The Planning Commission conducted a public hearing on the proposed interim use was preceded by published and mailed notice. The Planning Commission heard testimony from all interested persons wishing to speak and now makes the following: FINDINGS OF FACT 1. The property is currently zoned A-2, Agricultural Estate District. 2. The property is guided by the Land Use Plan for Residential Medium and High Density. 3. The legal description of the property is: All that part of Government Lot 1, Section 36, Township 116, Range 23, Carver County, Minnesota, which lies northerly of Trunk Highway No. 212; and, 27 acres in the west half of northeast 1/4 south of the railroad and north of Trunk Highway No. 212, Section 36, Township 116, Range 23, Carver County, Minnesota; 1 acre in Government Lot 3 north of Trunk Highway 212 being that part of the northwest 1/4 of the northeast 114 and the northeast r/4 of the northwest 1/4 in Government lots 2 & 3, Section 36, Township 116, Range 23, Carver County, Minnesota. 4. When approving a conditional use permit, the City must determine the capability of a proposed development with existing and proposed uses. The general issuance standards of the conditional use Section 20-232, include the following 12 items: a. Will not be detrimental to endangerthe public health, safety, comfort, convenience or general welfare of the neighborhood or the city through the stabilization and re - vegetation of the slope and the reduction in site erosion. b. Will be consistent with the objectives of the city's comprehensive plan and the zoning code by creating a future development area that may be developed consistently with the land use designation of the property and through the protection and stabilization of the slopes. The earthwork will be maintaining the site in a form suitable for residential use which is compatible with the Comprehensive Plan and this chapter. C. Will be designed, constructed, operated and maintained so to be compatible in appearance with the existing or intended character of the general vicinity and will not change the essential character of that area because the site will be re -vegetated and the slopes stabilized reducing site erosion. The aesthetics of the site will be enhanced with the elimination of the of the gullies/ravines in the site and the establishment of site vegetation. d. Will not be hazardous or disturbing to existing or planned neighboring uses because the grading and drainage will be contained within the site perimeters. Additionally, hours of operation are limited and specific conditions of approval will be in place and enforced by the city. e. Will be served adequately by essential public facilities and services, including streets, police and fire protection, drainage structures, refuse disposal, water and sewer systems and schools; or will be served adequately by such facilities and services provided by the persons or agencies responsible for the establishment of the proposed use since development of the site will be delayed until urban services are available. The use is temporary which does not need to be served by public facilities and services. The proposed grading will prepare the site for future development. The development of the site will require additional city review and approval. f. Will not create excessive requirements for public facilities and services and will not be detrimental to the economic welfare of the community since this is a temporary use. When the site is developed in the future, the development will enhance the city's economic welfare.. g. Will not involve uses, activities, processes, materials, equipment and conditions of operation that will be detrimental to any persons, property or the general welfare due to excessive production of traffic, noise, smoke, fumes, glare, odors, rodents, or trash. The proposed grading could result in a temporary increase in traffic, noise and fumes. The conditions of the approval will provide standards by which the activities should be minimized. h. Will have vehicular approaches to the property which do not create traffic congestion or interfere with traffic or surrounding public thoroughfares. Through the use of signage, limits on the hours of operation, and if traffic becomes congested additional limits on the hours of hauling operation could be instituted, potential traffic problems will 9 be mitigated. i. Will not result in the destruction, loss or damage of solar access, natural, scenic or historic features of major significance. The proposal will result in the removal of some existing canopy. However, the site will be re -vegetated and there will be less bluff impact vis -ii -vis the previously approved gradingtrestoration plan for the site. j. Will be aesthetically compatible with the area since the grading and re -vegetation of the site will improve the site aesthetics. k. Will not depreciate surrounding property values since the plan will improve the site and its impacts on the surrounding properties. 1. Will meet standards prescribed for certain uses as provided in, Chapter 7, Article III of the Chanhassen City Code. The planning report #04-27 dated August 17, 2004, prepared by Matt Saam, et al, is incorporated herein.

GAplanVorms\Development Review Application.DOC N The Pemtom Land Company 7597 ANAGRAM DRIVE CITY OF C ANHASSEN EDEN PRAIRIE, MINNESOTA 55344 IVED (952) 937-0716 • FAX (952) 937-8635 JUL 2 1 2004 CHANHASSEN PLANNING DEPT TO: Honorable Mayor, Members of the City Council, Chairperson and Members of the Planning Board and Professional Staff— City of Chanhassen SUBJECT: Moon Valley DATE: July 20, 2004 We are pleased to present to you a proposal for the Moon Valley Gravel Pit restoration. BACKGROUND: The Moon Valley Property, for you history types, was one of the early downhill ski areas developed in the fifties with a rope tow. The rope tow used an old tractor engine with pulleys made from car tire rims mounted on poles. Subsequent to that, the owners mined the rich gravel prevalent on the Minnesota River Bluff. The pit has also housed a high-powered rifle, pistol, and trap range. The proposal is submitted in accordance with the Settlers West Developer's Agreement whereas the current uses would discontinue and a modification to the existing restoration plan would be approved by the City showing the lower plateau being graded in such a way to provide slope stabilization, erosion control measures, and a storm water management plan. The proposal is being presented to the City with the consideration that the area will be rezoned medium/high density residential and office/industrial from its current A2 and BF zoning as guided by the City of Chanhassen Comprehensive Plan. Currently, an end use grading plan prepared by Sathre — Bergquist, Inc.in 1992 (the "1.992 Plan") has been approved by the City. This plan restores all the mined slopes, provides storm water ponding, and provides for approximately 8.5 acres of useable area for future building. This plan proposes grading 3 acres of existing wooded bluff and an additional .9 acres of trees. We do not believe that 8.5 acres of buildable area for medium to high density residential is adequate for this property to meet the goals of the City's Comprehensive Plan. In addition, the 1992 Plan adversely impacts the existing bluff area and results in a circular valley that does not allow for use of the natural beauty prevalent on the site. Therefore, our goal in the design of the submitted Grading Plan is to impact less existing bluff area than the currently approved plan and provide for more buildable area consistent with the Comprehensive Plan. The plan we submitted meets both of these goals. The useable area has been increased from 8.5 acres to 18 acres, 14 acres east of the creek and 4 acres west of the creek, and the bluff impact is only 2.6 acres instead of 3 acres. The impacted bluff area has been reconfigured to minimize the impact on the aesthetic beauty of the site. The proposed grading plan does impact the existing tree coverage. The proposed plan removes 7.3 acres of trees instead of 3.9 acres in the 1992 Plan east of the creek. The grading west of the creek would impact approximately 4.8 acres of trees. We would work with the City to establish a reforestation plan to meet any mitigation requirements of the Tree Ordinance THE PROPERTY: The land area consists of approximately 75 acres of steep slopes straddling a creek meandering southerly to the Minnesota River. Settlers West, a community of 58 homes currently under construction, is located along the northerly boundary. The Eastern portion of the site on the upper plateau abuts land in Eden Prairie that includes Settlers Ridge, a residential community of 220 homes, and the lower mined area of the site abuts the Richard T. Anderson Conservation Area. The entire northwest boundary of the site is along the Hennepin County Regional Railway Corridor. Extensive frontage along Highway 212 defines the southerly boundary of the site. PLAN: The lower area is proposed to be developed per the Comprehensive Plan at a future date when utilities are available to serve this area. The proposed plan at this point in time is to grade the site to create plateaus with average slopes of 4% or less where future medium to high density residential could be constructed in the future, while providing the necessary erosion protection, restoration, and storm water ponding. This grading restoration will prevent further unsightly and detrimental erosion from the site, as it currently exists. The plan as shown provides for attractive views of the Minnesota River Valley. Access will be provided from two points: one along Highway 212 near the existing entrance to the mine area and gun range, and another west of the creek in which a pleasant meandering private road would be constructed in the future traversing the hillside to reach a plateau with a beautiful view of the river valley. Extensive studies are underway regarding trees, topography, bluffs, utility service, wetlands, and storm water. Through the development review and approval process we will work with the City's goals in all of these areas and strive to exceed their vision for the guided uses of this property. We respectfully request your approval of this outstanding new neighborhood.

August 4, 2004 Robert Generous, Senior Planner City of Chanhassen 7700 Market Boulevard Chanhassen, MN 55317 Re: Moon Valley Gravel Mine Restoration Mr. Generous: The SWCD has reviewed the Moon Valley Gravel Mine Restoration plan. Please consider the following erosion control recommendations and comments. This site poses very challenging erosion and sediment control management. Erosion Control 1. If feasible, it is recommended to terrace the northern -most slope. In some areas the slope of 2.5 to 1 is over 500 feet long; controlling erosion and long term stability is going to be difficult. The engineers should take a look at the slope and determine the feasibility of breaking up the length of slope permanently. 2. Phasing is a very important management tool for erosion control. Stabilization of the toe (first 150 feet of the slope) is needed immediately upon final grade. Stabilization will need to be done in phases. Large portions of the site should not be left exposed over weekends or during forecasted heavy rains. 3. The slopes should be tracked with a dozer at all times. The dozer should be run perpendicular to the slope to track the slope. Tracking the slope is a passive, cheap erosion control method. 4. The NW `corner' of the slope will be an area of instability because stormwater will concentrate in the swale and possibly form a gulley. This area is north of soil boring 18, south of soil boring 14 and in-between soil borings 10 and 15. A terrace, turf reinforcement mat and slope drain will likely be needed in this area to promote long term stability. 5. Due to the steep slopes and long runs of the slope, straw fiber rolls may be needed to aid in stabilization of all the slopes with the MN DOT Category 3, 2S wood fiber blankets. The fiber rolls would help break up the length of slope and minimize erosion potential of the slope with the AN EQUAL OPPORTUNITY E?IWLOYER erosion control blankets. Please see attached straw fiber roll detail for a visual representation. Six-inch fiber rolls are needed every 15 to 20 feet. See attached fact sheet. 6. Proper blanket application is crucial for this site. The blankets must make 100% contact with the soil and stapled according to manufactures specifications. The staple pattern is vital to proper blanket function. The blankets should be head trenched as well. 7. Geotextile and riprap or geogrids or other approved stabilization is needed to provide toe protection; there is a chance the toe of the 2.5 to I may start head cutting without toe protection. 8. The seed mix specified (MN DOT 500) should be changed to MN DOT Native mix 340 (Sandy Mid Height, dry conditions —i.e. south facing slope). 16 pounds per acre application rate is recommended. 20 pounds per acre is needed for hydoseeding or broadcasting. 9. Depending on the final soil used, blanket application may be difficult. If the soil is too sandy, stapling the blanket over long runs will be futile. `Terracing' blankets or using strips of blankets with a heavy application of the seed mix (20 pounds per acre) and hydromulch will be needed. Sediment Control 1. The silt fence should be installed at least 25 feet away from the toe of the slope to provide storage and allow the silt fence to function properly. 2. As stated on the plan, the temporary sediment basins must be installed prior to grading activities. Berms may be needed to divert runoff into the basins along 212. Stormwater Management Subsurface stormwater movement should be considered with surface movement of stormwater. When considering stormwater management, installation of draintile at the toe should be considered to reduce any future possibility of sloughing due to saturation from ground water or slope seepage. If there are any questions please call the SWCD office Sincerely, Aaron Mlynek, CPESC Urban Conservation Technician cc.

The plans that were reviewed included the grading, drainage, and erosion control plan dated July, 16, 2004, and a Stormwater Calculations report dated July 21, 2004. Both were prepared by the Sathre-Bergquist firm. Hydrolocy and water Quantity r@lated comments are as follows: 1. The curve number selection of 69 for existing conditions seems high given the sandy soils prevalent on the site. The curve number should be lowered to 61 to better reflect current site conditions. 2. The curve number selected for proposed land use conditions appears low. (CN=76) For clarity and to better model small storm runoff from the site, the proposed medium density/high density residential areas should be modeled separately from the overall watersheds, rather than lumping them together. This will assist in future reviews in determining if the proposed development is consistent with the current proposal. 3. Times of concentration used in the model from the sheetflow calculations appear to be too long, resulting in underestimated peak discharges. The Manning's "n" value used in the calculations corresponds to dense grass conditions, which are likely optimistic given the slopes of the site. A better estimate can be made using either short grass or unpaved conditions to be conservative, especially given the steep slopes on the project site. 4. Overall, the rate controls provided by the proposed ponds meets the 10 year and 100 year predevelopment discharge rates. However, it does not meet the 2 -year predevelopment discharge rate. This could be accommodated by installing a small orifice and overflow weir outlet control structure without drastically raising the high water levels from the 10 and 100 year events. Changes resulting from comments #1-3 may change these results. 5. Drainage to Pond 1 from a portion of WS -5P is not accounted for in the rate control calculations provided for Pond 1. Although this area is not proposed for development, runoff from this area will affect pond operation.

Watershed WS -1 P does not have clearly defined drainage boundaries. Although it does not enter the portion of the site that is to be regarded, it will need to be better defined in order to quantify whether or not flooding will occur over TH212. 7. The proposed drainage diagram appears to show runoff from the Settlers West Development on top of the bluff draining to a concentrated point at the top of the proposed 2.5 :1 constructed slopes. These concentrated flows must be avoided and prevented in order to prevent severe erosion of the steep slopes. Runoff may need to be piped down the face of the slope at this location. 8. The west end of watershed WS -3P will naturally drain to the channel/wetland to the west, while the ultimate proposed plan indicates it will be directed east to Pond 2. Water quality treatment should be provided prior to discharging to the channel/wetland complex. A temporary sediment basin may need to be installed in this location until final development occurs and redirects runoff to Pond 2. 9. It is not clear how runoff from watershed WS -6P will be directed to the proposed Pond 1. The grading plans show sheet flow to the south, where it will intersect the proposed site access road. Based solely on contours, it appears runoff will sheetflow over the road and then will continue on to TH 212. Details regarding how water will be directed to Pond 1 should be included for review. 10. No details regarding the proposed pond outlets were submitted for review. At a minimum, they must provide skimming up to the 5 -year storm event. 11. The plans do not make it clear how runoff from watershed WS -5P leaves the site. High water levels at any proposed or current outlet may affect the high water levels in Pond 1. 12. The steep slopes proposed for the site (2.5H:1 V) will require substantial efforts be placed on erosion control during construction and vegetation establishment. The site should be thoroughly reviewed for erosion control measures as the current single lines of silt fence shown on the plan are likely not enough given the height and length of the proposed slopes. Water quality related comments are as follows: 13. The stormwater ponds should be designed to achieve a 60% reduction in average annual phosphorus loads. No details regarding the proposed nutrient removal efficiency of the ponds were provided. 14. Pond 1 appears to have a wet volume of 0.71 acre-feet and a mean depth of 2.45 feet. The minimum recommended mean depth is 3 feet for a water quality pond, in order to prevent scour and re -suspension of captured sediment. Bonestroo, Rosene, Anderlik and Associates, Inc.

The wet volume of Pond 1 is sufficient to retain the runoff from a 2.5 -inch storm over the watershed WS -6A - However, grading plans reflect that a portion of drainage from watershed WS -5P will be routed into Pond 1. Although this area is not proposed for development, it is important to capture the runoff contribution from this area for water quantity and quality calculations (see comment number 5). The drainage area routed to Pond 1 must be clarified and the wet volume must be equivalent or greater to the volume of runoff from a 2.5 -inch storm over the tributary area. Refer to comment number 2 regarding curve number modeling when re -calculating wet volumes. 16. Pond 2 appears to have a wet volume of 3.68 acre-feet and a mean depth of 3.83 feet. These parameters appear satisfactory. However, refer to comment number 2 regarding curve number modeling to verify wet volume requirements are met. In addition, refer to comment number 8 regarding the drainage area to Pond 2; the calculated drainage area to Pond 2 should be re-evaluated. 17. Overall, given the intent of the development (residential) and sandy nature of the existing soils, alternative stormwater management approaches (such as infiltration to reduce runoff volume) are encouraged for this proposed development.

The Minnesota Department of Transportation's (Mn/DOT's) functional engineering units and related areas have reviewed the plan. Please address the following issues before any further development: Pond #2 and possibly Pond #1 outlet into TH 212 right-of-way. Therefore a drainage permit will be required. Mn/DOT has received the drainage comps and maps and will retain them for use when reviewing the drainage permit. Please direct questions concerning this issue to Derek Beauduy (651-634-2233) of Mn/DOT'S Water Resources section. Since the intended long term use of this property is residential, please submit detailed information on any proposed access to TH 212 at the very early stages of the development process. Early Mn/DOT involvement in identifying a preferred access location will assure that safety and site distance issues are addressed. This will help avoid redesign work later in the development process. Please direct questions concerning this issue to Area Engineer Lynn Clarkowski (651-634-2103). ■ Any use of or work within Mn/DOT right of way requires a permit. Please direct questions regarding permit applications to Keith VanWagner (651-582-1443) of Mn/DOT's Permits section. As a reminder, please address all initial future correspondence for development activity such as plats and site plans to: Development Reviews Coordinator Mn/DOT - Metro Division Waters Edge An equal opportunity employer 1500 West County Road B-2 Roseville, Minnesota 55113 Mn/DOT document submittal guidelines require three (3) complete copies of plats and two (2) copies of other review documents including site plans. Failure to provide three (3) copies of a plat and/or two (2) copies of other review documents will make a submittal incomplete and delay Mn/DOT's review and response to development proposals. We appreciate your anticipated cooperation in providing the necessary number of copies, as this will prevent us from having to delay and/or return incomplete submittals.

Sacchet: Matt, do you want to give us your staff report, please? Planning Commission Meeting — August 17, 2004 Saam: Sure. Thank you Mr. Chairman and Planning Commissioners. First of all, let's get acquainted with where this site is located. If you will look on your monitor, the site is in the south end of Chanhassen immediately north of 212 along the eastern city limits of Chanhassen and just south of the recently approved Settlers West development. A little bit of history on this site: In past years, some 20 to 30 years ago, the site was used for, among other things, a rifle range and a ski hill. Most recently it has been used for a mining pit. In 1996, the City approved a grading plan and restoration plan for the site with the property owners the Zwiers. The plan is shown on your monitor. Basically, what the plan did is it concentrated on the east half of the site east of an existing wetland that goes through the site. The plan allowed the applicant to grade down at 2.5 to 1 slope to have somewhat of a developable area in the middle of the site approximately 8.5 acres. What I would like to highlight is the plan allowed the applicant to go in the bluff areas along the southwest corner here and the northwest corner. A little over 3 acres, I think the narrative says. It also impacted some trees. In looking at this, the applicant would now like to modify this plan to restore the site using some of the same guidelines, the 2.5 to 1 slopes and whatnot. So we now arrive with the current plan. The current plan, while it does utilize the eastern half of the site, also goes clear over to an existing creek or wetland and then also even farther west than that to the far western comer of the property that the Zwiers own. Again, staying with the previously approved plan in 1996 what that's done is proposing is to grade down at 2.5 to 1 slopes to this time vegetate the hill putting a wood -fiber blanket on it in addition to trees that staff is recommending. Some of the differences that I would like to highlight between this plan and the old plan, that the amount of bluff impact on this plan. The old plan went into this upper comer right here. This plan isn't doing that. They're limiting the amount of bluff impact that they have; however, with that they are proposing to go farther to the west here into more trees, approximately 7.3 acres. By doing that it provides the applicant with more developable area which, of course, is the ultimate goal here and the amount is plus or minus 14 acres on this eastern half. It wouldn't be developed until sewer and water got to the site in approximately 10+ years, around 2015. It's currently in the comprehensive plan to receive sewer and water. The development would come back at a later time. At this time they are only looking to grade the site and restore the site. One of the things that staff is recommending... if you could zoom in here Justin, just a bit. This western edge just along the creek, the applicant has a high point in here at which he quits filling and then starts dropping down again toward the creek. Staff is recommending that at about that high point we stop the grading operation. That would preserve more of the trees in this area. It would also preserve a little over half a bluff area so we would get additional trees that are preserved. We would also preserve the natural drainage of this area since it slopes down toward the creek. We want to preserve that to protect this wetland and creek area. We believe, as I said, it more closely follows the existing drainage and would eliminate the need for additional stone sewer in this area when it would be developed in the future because since its dropping off you would have to capture that water in storm sewer and route it all the way back over to this pond right here. The applicant is proposing in terms of drainage two ponds on the site which would be sized for full development of the site. We are assuming that basically the whole flat area would be multi -family housing which the land use guides it. So we would be set up in terms of ponding and drainage for future development. Erosion control is a big issue on this site. That's one of the City's goals with the site is to restore it and the applicant has done a fairly good of showing major silt fence of course on the site and then a lot of wood -fiber blanket on the steep slopes. We may have to upgrade the type of blanket 2 Planning Commission Meeting —August 17, 2004 because of the very steep slopes and the amount of water that would be coming off there. Overall, the grading plan looks good from an erosion control standpoint. I would like to point out there are two, the site is right here. Erie Avenue, a private street, is kind of in the middle of the site. There are two existing lots which are highlighted on your monitor that are privately owned. The Zwiers don't own them. So to complete the grading plan that they are proposing those lots would either have to be bought or some way come into play with this grading plan. We did put in a condition that access to the lots will have to be maintained throughout this process, at least until the Zwiers or somebody else would purchase them to bring them into the development. With that, we are recommending approval with the conditions outlined in the staff report and I would be happy to take any questions. Sacchet: Thank you, Matt. Questions for staff? Do you want to start Dan? Keefe: I have a couple of questions. Can we just go back to the erosion control just for a little bit and just comment a little bit more on what you think really needs to be done because just in looking at it, its really steep. From what we saw there's a lot of rutting going on and you feel that wood -fiber with, and there were a lot of trees called out for on the plan. Will it be enough to kind of stabilize that? Saam: The term wood -fiber blanket is really a general type term. There are specific categories based on steepness and the amount of velocity that the water can speed up to coming down the hill so it will have to be a certain type of blanket. It will have to be stapled in so it holds on the slope. The blanket will have to come in contact with the slope at all times. Also, the areas at the bottom of the slope right around here where my finger is going, specifically in this comer here, this is kind of a swale or ditch if you can imagine coming down the slope where the water would be concentrated. That will be a big area where erosion could occur so we will have to stabilize that. I think the staff report goes into some detail on that. They also have to put in sediment basins to control the drainage on the site but I think we can work through it. Is it your typical one? No, definitely not but I think there are items that we can use in terms of blankets and different types of silt fences and bales that we can use on this site. Keefe: Is the highlighted area, the green area that you got there, is that where most of the trees would be or are we looking throughout the site? Because I think he called for, I don't remember, is it 20,000 trees? Is it mostly on the hillside or is it in the flat area? Saam: That's my understanding. It's the smaller, bare root I think they call them? I'm not a forester. They are smaller type trees. I think the applicant's done some of that work before me. They can go into some detail. It is my understanding they would all have to be hand placed in there. With that slope I think the most you could get up there is bobcats and that sort of thing so we are not talking about any big spade coming in there or anything like that. Keefe: Can you comment a little bit more about the trees that would be removed? I can't speak to the quality but it seems like the whole area hasn't been really maintained all that well for a number of years. The quality of the trees in the areas that they would be removed, it guess it would be the center area, any comments in regards to that whether they are poor quality with all 3 Planning Commission Meeting — August 17, 2004 the rutting which has gone on out there. Are we looking at trees that are falling down a lot? Any comments you can make on that? Saam: Just a couple. Again, I'm not a forester; I'm not a tree expert. Just from visiting the site there are certain areas with what I would call nice trees and there are some other areas where I would say they are more of the scrub -type variety. Kate, would you have anything to add? Aanenson: Again, I think if that was a trade-off as we go out and visit the site to look at if there are areas ... I think that is one of the points the applicant brought out. When you look at the one knoll, maybe its not as good there but certainly on the top one back towards the creek, the trees, while they may not be as high quality, they are preserving the existing slope and providing some habitat. I think that staff's position is for maybe looking at the one finger or knoll that sticks out, maybe that might not be as high quality. Could that maybe be removed? Maybe originally the applicant chose not to remove it but we would treat that as a minimum ... that creek, preserve that instead. Saam: Just adding off that. That's a good point. With staff's recommendation to save what I'll call the western half going down to the creek, if we could save the existing vegetation there it would greatly minimize erosion and that type of thing, no matter the variety of the trees. Keefe: I have one last question. In regards to the 1.8 million cubic feet of material that would be removed, could you give us a sense of where that on this plan, is it throughout the entire plan or are we talking just in the flat area and does that consist of what? Are we just pushing the dirt around in there that we are going to remove that is sort of the topsoil? Are we talking digging down? Saam: There is a number of questions in there but it is my understanding that the 1.8 million number is the excess number that they would have. In other words, the number that would have to be hauled out. As far as where they are cutting, this are is being cut down. Initially, up here they are restoring the existing cliffs out there where the erosion has been happening, but then as you go down into here they are cutting at 2.5 to 1 and that's to get this plateau area for future development of the site. Sacchet: Thanks, Dan. Bethany, any questions? Tjornhom: I have a couple of questions. Looking at the map, where does the creek start? Does it just start where that little circle is? Does it just start there like all the sudden there is a creek or is it fed by something else? Saam: This up here I think you're referring to? This is the Hennepin County Regional Corridor or LRT Trail. There is drainage from Settlers West which eventually comes down there. It's a ditch -type system, I'll call it. Everything in this area eventually goes to the Minnesota River valley so its all tributary to that and that's what I would call this, the beginning of that wetland. Tjomhom: With the grading and you've mentioned when it gets to that slope by the creek, you're going to stop the grading, correct? Planning Commission Meeting — August 17, 2004 Saam: Yes. Tjornhom: So then you won't have erosion going into the creek? Is that happening now? Is there erosion going into the creek now? Saam: No, that's not my understanding. Where the erosion is happening now is inside the site. Basically, it's been carved out. It's kind of like a bowl now with very steep slopes, 1 to 1 or more in areas. Tjomhom: So right now the creek is protected and its not really... Saam: Yes, as far as I can tell the existing creek is protected. Tjomhom: That way then, even after the grading is done and... Saam: Correct. That's what we are recommending. Tjomhom: OK. I have a question with the trucking also. That's a lot of trucks coming in and out with fill and without fill. How long do you think it will take? Saam: That was a big concern of ours when we talked to the applicant, too. As the staff report says, the applicant is proposing a five year kind of phasing plan for the project and because of the amount of excess that will have to be trucked out, frankly it will take probably that long to find homes for 1.8 million cubic yards. A rough number that we use in engineering is 10 cubic yards per truck. Maybe you'll get some more if it's bigger than that but usually you get 10 to 12 so that's quite a few trucks going out of there. Maybe that thing can go into this but they are planning to do it in phases so maybe it's a fifth of that number, 30,000 to 40,000 one year that's trucked out and so on over five years. Tjomhom: This is a crazy question but, is this a seasonal operation or will this be happening in the wintertime also? Saam: That's a good question. I would guess it's without snow but maybe that's something we should ask the applicant. I haven't asked that. Tjomhom: OK. And this is just for my information also, where all the gravel is obviously what is up against, what they will be filling up against, is there a problem putting dirt along that gravel wall? Will that settle any way or how does that work? Saam: There's always that potential but they will have to compact it and use certain construction techniques to make sure that it all doesn't slough off in a rainstorm maybe. Tjomhom: That's what I was thinking. 5 Planning Commission Meeting — August 17, 2004 Saam: And that's why it's key to have the erosion control in place before really the big operation starts. That's why you want to have your perimeter silt fence up and sediment -type basin so if say it would slough off it wouldn't leave their site and it would just be their problem to put back into place because what we don't want is for it to affect Minnesota river valley or neighbors. Tjornhom: Will they kind of wrap or put something on that gravel before they would start to put fill up against it or no? Saam: Wrap I don't think would be the right word. Running dozers perpendicular to the slope, certain construction techniques to make sure that it gets compacted. Tjornhom: So no material or anything to hold in place? Saam: Material? Dirt. Yes. Tjomhom: I guess that's why I'm trying to figure out. When you put the dirt and sand together they compliment each other where all of the sudden, sand is obviously more porous than dirt is and so when sand is taking in more water will that start to erode the dirt from the hill? Saam: I guess I'm not following you. What they'll do is remove the topsoil wherever there is some and fill in with the existing dirt on the site. If they find other sand that will go back in but it's predominately clay is out there among other things. I know there's been some filling of a lime particulate out there. Maybe the applicant's environmental engineer can go into that a little more too. Tjornhom: OK. That's all. Sacchet: Thanks, Bethany. Kurt? Papke: Just two questions. To follow on the fill issue; if it's going to take five years to get rid of all the fill, does the applicant complete their grading job and then make a big mountain in the middle of the plateau that has to be managed over five years and where does the fill come from during that five years or does the grading happen over five years? Saam: The five years is the applicant's proposal or schedule to complete this entire operation but what we are proposing is on an annual basis they obtain a grading permit from us and this is an interim use permit, but maybe we'll need an interim grading plan to show are they going to work in this comer now and, if they are, how is that going to be stabilized? Maybe we will need erosion control there that will come down in the future. Is that getting at what your question was? Papke: So the grading will be sequenced and so as the grading is done the fill will be removed so we won't end up with a mountain of gravel for five years? That's kind of what I was getting to. Planning Commission Meeting — August 17, 2004 Saam: Correct. As I said earlier, maybe they'll take out 30,000 to 40,000 a year over phases. Papke: But it won't accumulate in one spot either during that period of time? Saam: Again, they have an excess so they can spread it out if they finish in the fall, reseed it, and then maybe they won't come back until the next spring. We need additional information right now from the applicant to get an idea of what the sequencing or phasing is. Papke: The only other question I had is on the reforestation, raising 10,000 seedlings out there with deer eating their dinner every night off the seedlings and so on can be a real challenge. Is there any kind of plan in place for how we maximize the survival rate of whatever goes in there? Is there a part of the plan that addresses that? Aanenson: I believe the Forester did talk to the applicant this afternoon about the tubex trees. It is the assumption that we're putting in more smaller sapling types and that they would also be in tubes and that would protect them from the deer and the rabbits and that they would be protected as we move along with a security, to make sure that they survive. Papke: Is there any kind of black dirt going in? Right now you would be planting trees and gravel in essence. Saam: No. What we require, as we do with every new development, the four to five inches of black dirt at the surface and then they vegetate on that. If they don't have it on site they'll have to haul in some black dirt eventually. Papke: OK. That's all. Sacchet: Thanks, Kurt. Craig, any questions for staff? Claybaugh: Most questions have been asked. Did the City Forester have any specific comments? I assume she's been out to the site? Aanenson: Her comments are in the staff report and again, the goal that we looked at and going back to the original plan that was approved through litigation was just, we said re-establish the slope. The City's goal is to get trees back on the slope and that's what the applicant wants to do too. Then the property does become part of the MUSA and it is available or ripe for development. Then they've got the vegetation in place. So we've recommended a variety of different saplings. We've put a lot in there, 20,000. I think they were a little shocked at that. We're looking at six to eight inches tall and that gives us a higher survival rate, the spacing requirements and issues ... Not all of them will survive but ... comprise between that but we think that's very doable. Claybaugh: Kurt asked the first half of the question of just getting those seedlings the best start possible. Is there a monitoring process in place? Planning Commission Meeting — August 17, 2004 Aanenson: I think that was the first issue that we had. We did go with the applicant and looked at some of their other sites that they've done that are on very steep slopes because we wanted to increase our confidence that this was the right way to go so we did look at some other projects and believe that it can be successful. Claybaugh: This may be a question better suited for the applicant but I'll go ahead and throw it by and you can check right over what you have there. Actually, at 30,000 to 40,000 cubic yards per year they will be out there a lot longer than five years to export over a million yards. You've got the first phase coming up. I don't know if you know how many cubic yards are involved with that or what kind of a timeline is associated with that? Saam: I'm sorry. My math was off. It would have been about 300,000 to 400,000. The timeline again is five years. Claybaugh: This first phase. I'm trying to break it down a little bit so we can get a little better perspective so it... Saam: Sure. Let me try to highlight that as much as I know and the applicant can add anything he wants. As far as we know, they want to get started along this northeast comer. Claybaugh: Down at the toe for Settlers Ridge, correct? Saam: Yes, at the southern end of Settlers West to get that established and then I believe its basically moving from east to west after that. Claybaugh: Again, I'll come back to the question that Kurt asked. Are they planning on staging any of this material, of this excess on site or are they looking at exporting it as them move it to avoid handling the material twice? Saam: That I don't have a handle on. Maybe that's something that the applicant can add. Claybaugh: They already covered the topsoil element... that's really all the questions I have. Thanks, Matt. Keefe: Known environmental issues that are out there. I see that a phase I is called for. Do we know of anything significant? Saam: In the environmental assessment the phase I is related to, we know a rifle range of shooting range was at one time going on at the site so we are thinking there may be some lead - type contaminants so we just want to have an assessment done to see what that will shake out. Sacchet: Actually, I have a couple questions, too. One thing, and I don't know whether this can be answered, somewhere I picked up on a, I think it was a DNR map, that in that area we have some of the original growth left in terms of the trees which is actually very special from an environmental viewpoint. I don't think it's mentioned in the staff report but I wondered do we have any knowledge about this at this point? It was one of my concerns I brought up when we Planning Commission Meeting — August 17, 2004 looked at Settlers West and I think I would like to also consider that point in the context here, if indeed there is such a point. Is that not something that has come up to your attention so far? Saam: No, not to my attention and we did send it out to review agencies so maybe we haven't heard back from the DNR yet. Sacchet: OK. In terms of the math of what we are actually doing, and obviously I'm mostly interested in the math of how much trees we're cutting, personally. We're cutting 7.3 acres just on the east side of the creek, that's correct? Saam: Yes. The 7.3 is... Sacchet: ... what they're proposing. Saam: Yes. Currently and that's only on the east side. That's a good point. Along the west side of the creek there's another... Sacchet: ... there's another 4 acres, right? Saam: Yes. 4.2. Sacchet: Now, one thing I'm confused and you explained a little bit how you were proposing to reduce a little bit the tree impact by the slope on down on the other side to what's the creek. Staff report has two different figures. On page 3 it says 1.6 acres and page 5 it says 1.4 acres will be saved. Which one is the accurate figure, do we know? Because I was just curious do we have a clear idea of how much we are saving? It's not a huge difference. Saam: This is a blow-up, a 50 -scale plan of just the eastern half of the site and what I did here was draw in red basically the line of where we are proposing the grading would stop. Sacchet: And that would be the existing 756 contour? Saam: Yes. Their last proposed contour would be this, and you can't see it, but it's the 756. So west of this line on this area, that would be preserved. I actually used an instrument, we have to calc up that area, and I came up with 1.6 acres. Jill has 1.4 so it's right around that 1.5 acres of preserve area. Sacchet: OK. Good. Has that been discussed with the applicant or is this a new... Aanenson: He's aware of... Sacchet: You make a point that then there would be trees cut for the construction at that point, if any, where the buildings go, like a custom -grading type of approach. Is that the idea? Saam: I haven't seen any development plan per se with building pads and that sort of thing unless the applicant has something to share tonight I haven't seen it to that much detail. 0 Planning Commission Meeting — August 17, 2004 Sacchet: We're not to that level... OK, that's fine. Now, one question I have with creating those 2.5 to 1 slopes, we're actually creating new bluffs, is that accurate? Does that meet, how steep is a bluff? Saam: Yes, that's a good point and it's something, I didn't think of it in that fashion but yes, that slope is 40%, I believe, and our bluff ordinance says 30% with a 25 -foot elevation difference. Sacchet: I was just wondering if my memory was accurate. 30 -something percent. So really all these slopes are going to be considered bluffs? Aanenson: Yes. Saam: Yes, but again, we are restoring a bad situation, by that erosion we'd be vegetating that area. Sacchet: So once they are revegetated would they fall under our bluff ordinance? Saam: Look at Kate for an interpretation. Aanenson: I'm not sure if it's pertinent to the discussion in the opinion of ... (the tape was changed at this point)... density credits nor are they taking any density credit for that area. Sacchet: Well the concern is that bluff has special setback requirements, doesn't it? Aanenson: Yes. Sacchet: We'll cross this bridge when we get to it. Aanenson: I'm not sure it's going to impact it in that format. It doesn't have development density right on that part. The only part we did talk about is if we want to guide the berm because the ordinance doesn't address tree removal except for the fact that you replace it. But it does address the slope issue. Keefe: Would the bluff, now assuming you make bluffs, right? When they come in and presuming somebody wants to develop it then they would have to deal with the bluff setback. Is that kind of what you're? Sacchet: Well I wonder what, I mean that is something to be certainly considering because that may be an impact that... Aanenson: It's a 30 -foot setback. More than likely that type of product is going to have something... Sacchet: It's going to have room around anyhow. Alright. We'll deal with it when we get there. For ignoramuses like myself, what's a dozer? 10 Planning Commission Meeting — August 17, 2004 Saam: I'm sorry, a bulldozer. Sacchet: As in bulldozer? Saam: Yes. Sacchet: It says here the slope should be tracked with a dozer at all times. Saam: Yes. Sacchet: So, a visible dozer. Just to beclear. A lot of the conditions, let's quickly go through these things, too. One, condition 6 talks about an escrow letter of credit to be required for $619,000. How is that figure calculated? Saam: It was just grabbed out of the air. I'm kidding. We got a cost estimate from the applicant's engineer as we always do. In terms of the overall grading of the site what it would take then we review that, tack on 10% and that's how we arrive at that figure. Sacchet: OK. So that's a calculated figure. Aanenson: Let me qualify that, too. I think one of the things that we are looking at if we do a phasing plan that we probably have a rolling letter of credit which we do on a lot of other big projects is when there is open landscaping, if there is so much open land we just move that to the different phases and that would be something that we'd probably look at with this project, too. If we're doing it in a five-year, where we would have just the amount in escrow needed for that portion to re-establish, if that makes some sense. Sacchet: OK. The trees we're requiring, the staff report talks about between 9,531 and 38,080 trees which is a pretty big range and in the condition you say approximately 20,000. There seems to be a big range. Are you not comfortable being more specific or what does it depend on? Aanenson: The note that I have from the Forester was that 20,000 is what she's recommending for replacement. Sacchet: OK. So the 20,000 is the figure we're going to go with? Aanenson: Correct. Sacchet: OK. Those two properties, 230 and 240 Erie Avenue, at this point they are being left alone? Aanenson: Correct. 11 Planning Commission Meeting — August 17, 2004 Sacchet: OK. In terms of the Comprehensive Plan, and I think that's going to start wrapping up my questions, we obviously have a juggle here between a relatively bad situation with an abandoned rifle range and a mine with a lot of erosion, and on the other hand, we have a relatively sensitive natural environment around it. I assume with staff bringing this forward you believe this is consistent with the Comprehensive Plan in terms of the objectives of being compatible with the revegetation and ultimately with not destroying any natural scenic or historic features of any significance? Could you speak of that just a little bit? Aanenson: Yes. Let me just kind of refrain this. When the applicant came in to do Settlers West, what we decided on that is we wanted to, as a part of that, was to get rid of some of the problems that were on the bottom, this piece that we're talking about tonight. Specifically, the shooting range, the cell tower, those were the things that were a nuisance and actually the gravel mining operation itself, and re-establish the slope that eroding terribly and actually get better vegetation on the slopes. That was the overriding goal. Ultimately, while doing the grading we're still a number of years, at least 10 years out, before municipal services are there so if we can get the slopes re-established and the vegetation growing, we think that makes sense to get the site cleaned up and re-establish that slope for Settlers West and the other Settlers side. We think that is a good thing. Saam: I'll just add one more thing. Again, let me reiterate, this applicant has the right to do that initial grading plan which went into the bluff, didn't take out as many trees but took out more of the bluff. We didn't really have a reforestation plan it is my understanding with the original 19% plan. Jump ahead to now, we are getting a revegetation plan, not as much bluff destruction, with staffs recommendation not as much tree removal. Still quite a bit but not as much. Sacchet: So you believe it's a healthy balance? Aanenson: Correct. Saam: We do. Sacchet: My last question, I believe this was the letter actually from the applicant, it makes a point that extensive studies are underway regarding trees, topography, bluffs, utility services, wetlands and storm water. It might be more of a question for the applicant but have you seen any of those? Saam: I guess I'm not sure if he's referring to the feasibility type study. Certainly the City isn't for this area right now. Sacchet: We'll let the applicant speak to that one. That's all the questions. Thank you very much. With that, I would like to ask the applicant if you want to come forward, if you want to add some more and share your vision with us here. Please, if you can state your name and address for the record. Herbst: Good evening. Dan Herbst of The Pemtom Company at 7640 Crimson Bay in Chanhassen. Good evening Mr. Chair, members of the Planning Board and professional staff. 12 Planning Commission Meeting — August 17, 2004 also want to introduce Justin Larson. You met him during our Settlers West. Justin's with Sathre-Bergquist. His sidekick has got his kid playing hockey tonight, Bob Payette, so he's missing. I'm also fortunate to have Jim Aiken with us, an environmental engineer with McCain & Associates, does all kinds of environmental issues throughout the state, public and private, and also Dan Cook from The Pemtom Company. The reason I'm here is that I was able to acquire the upper plateau from Mrs. Zwiers and came before and got Settlers West approved and it was very important to me, not only what happened up above, but what was going to happen down below because I had a vested interest in it. I negotiated with her a five-year option because I, like you, want to see that restored and I want to see it revegetated and, as I got into it, she asked me if I would take it a step further and said what is the City's Comprehensive Plan here and what can I expect to do with this piece in the future. I think to just fulfill the requirements of restoration and do the 1992 plan that was in your 1996 settlement I think wouldn't do justice to the site or to your Comprehensive Plan. As I indicated to you out in the field, you took a very bold approach with guiding 70 plus acres of that site for high-density housing. I think there is some real potential to do something very creative there. Although you didn't see any progress out there tonight, I feel there has been great progress. We were able to start our development up on top and as you know the erosion that has been coming off that bluff where Settlers West is, hopefully a month from now when we do that berm up on top and put in the storm sewer system, all of the erosion that's been coming off of that northeast corner will be eliminated. We got that transmission tower removed to the great pleasure of people in Chanhassen and people at Settlers Ridge on the east. We got the range shut down. We got the dumping and filling stopped and now I think, although you didn't see any of that, to me that's been great progress because I've been listening to the range and watching things erode out there and gotten many letters in your file also from the City of Eden Prairie. They paid dearly for the Richard J. Anderson Conservation Area and that's been eroding through the years and the owner, who is now deceased, was not being very cooperative with the City. I think we've got all that in place now. We've got a developer's agreement with you. We've got a developer's agreement with Eden Prairie. Now we want to move forward and I think this is the first step. I take the blame for comparing what I submitted to you to the 1996 plan and comparing the development potential of that plan to what we are proposing because I don't think, again, that does justification to the site. Tonight I think it's important that we deal with what I've submitted and talk through our phasing plan and talk to the issues you have, but then come back to you with additional studies about trees; however, there is old growth there, what kind of trees are there and then come back to you with what may potentially happen on that site. I don't know, it will probably be a few years down the road when you are going to be looking at redoing your Comprehensive Plan but we want to be very much a part of that. As ugly as that place looks, I'm really excited about it. We were all looking to the north and to the west but if you turned around and saw the beautiful views and you saw the potential there to create some plateaus for housing, it could be a very, very unique site, something that you don't have in the City. I think if we work for that vision, work for that dream, I think we could really, really have something there. I don't want to go through all the arithmetic because you have it in front of you but yes, the original plan had less bluff than we are proposing now being, had more bluff being damaged but more trees. I love trees. I spent millions and millions of dollars in my life replanting trees and, to be honest with you, I've had greater success planting and growing than I have trying to maintain trees. All of the goals I have for that site are the same as yours. I would like to maybe, should be just go through some of your questions with the trees? Let's start with the trees because I know they are all important to 13 Planning Commission Meeting — August 17, 2004 all of us but you know I've been working with Jill and Kate, very sensitive people to the tree issues, and you get mixed readings every time you go to get opinions. We called one DNR individual and he said, as indicated in your site tonight, we have too many trees up there. Let's look at planting some unique prairie grasses. I said I don't think they're going to buy into that deal. Then I talked with the other lady at the DNR today and she said she would really like to see about 500 of bare -root or root stock planted per acre which would be about 10,000 trees. She has them available on a first-come, first-served basis. There are no guarantees but she has some 6:42" material which we could buy from her. She's recommending that we do a mixture of an oak and my favorite little tree is that eastern red cedar. It's a very tough tree and we're talking about putting on a southern face slope. Although I think we kept talking about granular material out there, there really isn't much good granular material left out there. It's all been picked over for the last 75 years and what's there is very, very marginal. In fact, some of the banks you were looking at weren't granular at all. It was basically clay material. That is going to be a good basis for us to do a restoration and do the build up of those 2.5 to 1 slopes and the 40% slope there and then I think you've got some very stiff requirements for us from that and from the Carver people of how we're going to re -seed that and protect. I took staff out to Settlers Ridge and showed them similar banks along the Flying Cloud Airport. We did some 2.5 slopes out there. We put fiber blanket in and we put bare root in there and it's doing quite well. I'm very proud of it. We took the extra step. We didn't just plant it in the ground. We put the base material on it. We put the tubes on it. We put the stakes. You also need a lot of luck when you've got that kind of drainage sloping. You need moisture at the right time of the year but I think we can do a good job. Also, we had some very severe sloping at Settlers Ridge, the project to the east. A very severe ravine, much more severe than we're dealing with here and I've taken most of your staff out there. Those have no trees on them but the vegetation from the fiber blanket and the natural material that's coming back in from whatever it is, weeds, or whatever is doing a wonderful job and is very, very, very attractive so it's done quite well. Anyway, when I read the staff report I had the same issue. What's gong on here? 9,500 to 40,000 roughly in trees. I think, in my mind the DNR submittal would be very good, 10,000 trees, but if Jill's insisting on going for the 20,000 and we can make a good buy on those next spring and we could do it in phases, again I want to do a great job there on those trees. The trees will be important once we get it all established but we've got to get those hills established first, we've got to get the fiber blanket set, we've got to get the grass to grow before we start marching up there with people and disturbing that and start to plant trees because we can't a machine or a bobcat up there. On the grading issue, we have no intentions that I'm aware of mining that site and stockpiling in the middle. As you know, that dirt business, to move it twice is a costly deal. I think we've like to do it in the five phases we talked about and for my own self -interests I want to get Settlers Ridge and Settlers West taken care of, this phase of this neighborhood. This is pretty much established already although it exceeds, it's a little steeper than 40% but we build there second and protect the parkland there and then move our way through five years hopefully if we can find a home for that material and do this in stages. I think it's easy to look at this site and say gee, I don't want to lose all those trees and I want to do that. I may want to limit the development area and hopefully when you come in with a plan you'll open it up and take another look at it. I think there is some danger to shrinking what we have here. Ordinances get stricter and all of us get tougher on our requirements of how we develop things but I do think I was anemic here in what I submitted to you. I think I really should have submitted to you a visionary type plan where we could fulfill your Comprehensive Plan and put a, this proposal only has 18 usable acres and we'd 14 Planning Commission Meeting — August 17, 2004 have a hard -press knowing what I know in the marketplace today to probably even get 200 housing units up there. That really isn't a real creative plan in my mind. We can't get a good mixed use. It's going to be also tough with 200-300 housing units to bring that pipe from 101 all the way down to this site and justify that so I think we want you to work with us and come up with a visionary type plan. I would like to expand in the future with you, in discussions with you, the development area. If we are able to get a good plateau up there, maybe 25 acres of land to use instead of the 18 we could come up with a good mixed use. Some of the land that's not shown on the plans to the west is guided Office/Industrial. I think you can vision neighborhood commercial and office. Some of the things you saw in a grand scale at Edinborough, on a smaller scale here. That type of product is going to be great for the City. It's going to fulfill some of your housing needs that we're going to have to convince you of that. It's going to give you additional park fees. It's going to give you additional revenue stream. Most of these townhouse projects, I talked with Gordon Hughes today, the City Manager of Edina, again he'd like to bring her back there and tell you what they did but, very little of what's out there is maintained by the City of Eden Prairie except those bridges going over the streets. All of the interior streets serving all of those condominiums and townhouses, the senior high rise, the offices, the retail and the theatre, are all privately maintained so the revenue stream coming into the city is phenomenal because you don't have the revenue going out. I think we can show you the numbers on that eventually if we can get the densities and the land mass to create a great plan for you. Any other questions? Sacchet: Questions for the applicant? Keefe: Are you OK in establishing the ponding now or later on? Herbst: No, I think the ponding has to come in real early. We didn't take you around, we didn't have time for that but there is some slurry areas out there now that have been holding runoff but I think we want to fix those up. Keefe: OK. If I'm looking at pond one, access to the two existing homes, it isn't clear to me exactly how, I think they stay and you ... their access would be through the first pond. That's how it appears on the plan and I'm curious to... Herbst: That's probably at least five years out. The grading, as I see would occur here, this pond will take care of all their farms through here. This would be obviously before we could go into here. We've got to work out a hardship situation with the two homeowners and then we've got to come in with a specific use plan for that because, this is showing the ultimate use with a driveway going up to the site and more ponding coming here before it gets to the creek. That pond is just there to pick up the drainage so it wouldn't get to the creek. Keefe: It is a part of what we are approving? Herbst: Correct. Keefe: It needs to be worked out in terms of where the exact location of the pond would be? 15 Planning Commission Meeting — August 17, 2004 Herbst: It cannot be accomplished until we, there's easements, that the two homeowners that live there have a legal interest in so we have to treat those homeowners fairly. We have to work out that easement deal. Sacchet: Has there been any discussion with those homeowners? Herbst: Dan Cook has talked to I think both of them and I'm not in the position since I'm on the option end of things to be purchasing the property but I think as we move there Mrs. Zwiers and myself have got to work something out with those homeowners. Sacchet: So that's still to come basically? Herbst: Yes. Sacchet: Sony, I didn't mean to interrupt. Any other questions? Claybaugh: With respect to your phase I, could you give us a little bit of a overview in terms of timeline in what you see going out for export, just to put that in perspective? Herbst: I would, I'm just guessing, and maybe I'll let Justin answer that but I want that done this fall because I've got housing up on top and it's not a real large site. It's pretty steep but I would like to come in and get the permit for that and bond for that and have that accomplished this year because of what's going on up above. Quantities and material, do you know what's in that first phase? Justin Larson: In the first phase we haven't really ... but I think it would be probably minimal, to tell you the truth just because of the way the slope is... Herbst: Probably under 100,000 yards I'm guessing. Sacchet: So what you're saying is the first phase you pretty much balance the material? Larson: That's right. I don't think until we start going west that I don't think the earthwork will be extensive as far as having to export. Claybaugh: In terms of your months of operation from year to year over the five years, what do you anticipate? Herbst: Well, I think it depends on how granular it is. To me, it doesn't look real granular. Unless it's granular, it's hard to work with during the frost season but that phase I that you're asking about is very important for me to get done this year if at all possible. Claybaugh: I'm just trying to get into the quantities that you would be exporting and the effect that may or may not have on... 16 Planning Commission Meeting — August 17, 2004 Herbst: I would doubt if there's any export there in that first or second phase. There's enough up and down material out there that we got to get balance out and get this pond taken care of before we're going to start looking at going down the road. Claybaugh: Have you exported this kind of quantity on any other projects that you've done? Herbst: I have not. We're grading over a couple billion yards out at the airport right now but it's balancing. Last year I think I told you I had a 100,000 on that first site at Hennepin Village and even though it was granular, it's difficult. Sometimes having excess material is a blessing but mostly I found it to be a curse. Claybaugh: That actually just generates a little bit more concern that there's only 100,000 going out in phase I. That puts the bulk of the material on the other phases. Have you considered what kind of impact any whole schedule would have on how you would tackle that? Herbst: I'm going to leave that to probably the grading contractors. I think we can work with Matt on that. He's probably more experienced with large quantities like this before. Claybaugh: Nicely deferred. Herbst: I have not experienced that so I want to be honest with you. Papke: I'm not sure if this is a staff or an applicant question but one of the things we haven't touched on yet is how much of this is visible from the LRT trail? There's some of the most spectacular vistas in Chanhassen are on that trail and I'm sure, I know there's like a park bench up on the trail there where you can look down into Shakopee and I'm having difficulty visualizing where some of those site points are in relationship to this because I would hate to see us end up with what is now a beautiful, the most beautiful view in Chanhassen looking down on something that isn't attractive. Herbst: If your talking about up above, I guess you've got to pick a point, but the trail itself you can see it right here, more than 100 feet down below this right now. The trail is very recessed... Papke: But there are a couple of spots where it peeks out there and I'm not sure exactly where. Herbst: When you start up at the trail when I've jogged it or walked it, you can look down, you're kind of looking more very southwesterly down that chute to Shakopee and I don't think anything here is going to be impacting that. Papke: That was my major question. So none of this is visible from the trail? Aanenson: Ultimately, when it's developed you may see something but the goal was to revegetate it so you kind of catch up with that but as far as knocking down the bluff, that was one of the reasons why we pulled back the one slope on the other side of the creek. When your even on Erie, you can't see your crossing, you still wouldn't be able to see. And that's the topographic break that we're trying to maintain. 17 Planning Commission Meeting — August 17, 2004 Papke: OK. Herbst: As you know it's pretty severely cut. Everytime Igo down there I say how in the world could they do this with horses? It was a major, major cut so it's very recessed. Sacchet: I asked you this question when we looked at the site earlier tonight and I would like you to address this for the whole meeting for the record also. Why do we have 1.8 million cubic yards of material that have to leave the site? Why can't it be balanced more on site? Herbst: I think that was the fust question I had. The engineer said it's just truly impossible. If you were to put this material back in, all you would have was, the bluff probably came way, way out at one point in time and dropped way down. If you were to try and balance the material and leave that 1.8 on the site there would be at some point in time you're just going to push that bluff further and further out towards 212 and you're not going to have any land left to use. As you know, your standards, we're even showing I think a 4% rise stepping up this thing and we're still taking out that many. If we were to make it a little more level there would be a lot more material coming out of there. It's very close to what was approved in your original plan to restore that site. Sacchet: Do you remember how much would have to come out with the original plan? Herbst: 1.8, believe it or not it's pretty close. Sacchet: So it's pretty much the same amount. That actually stayed the same even though you are doing a larger space? Herbst: Yes. Sacchet: That's a very good reference point. Herbst: From what I talked to you about tonight is pushing the envelope a little more. Sacchet: Right, right. What's your, do you have a sentiment about the proposal staff made that the grading towards the creek on the east side of the creek that you would stop at, what was the elevation, 756 and kind of leave the other side untouched for now? Do you think that's a good idea? Is that creating a problem? Herbst: I think that it's a catch 22. I think it makes sense because Bob Generous and Kate make a statement in there that we could still use that area but it's a product that makes it more complicated by going up vertically. Even at Edinborough and Centennial Lakes the only vertical product I had was that senior rise, that building there. That's a very tough market. People are comfortable with three floors, sometimes four, but after that it gets to be a real market grind. In fact, some of that product, the first phase of Edinborough was basically designed with some walkout to that four-story to kind of discourage the elderly from buying them because they wanted to cater to young people to keep them there. That's what Edina was lacking was housing IV Planning Commission Meeting — August 17, 2004 for people that want to work there and I think you start pushing that product up and you lose that market appeal. Sacchet: So what I hear you say is you're OK with this for now since it's going to be calculated into the buildable area? Herbst: I don't want to see it shrink because it could come back to bite us. Sacchet: I wouldn't really shrink your buildable area. Herbst: Yes, it does. It shrinks the amount of land that would be open for buildable area... Sacchet: It does shrink. Yes, that's right. It shrinks it by 1.4 or 1.6 or something like that. Herbst: When you get old you hate shrinkage. Sacchet: So that's contrary to your aim. I understand. Are you OK with the conditions basically? The escrow amount? Herbst: The issue I've worked out with Matt, letters of credit. Most cities allow us to do development bonds and there are not as expensive but a letter of credit is very costly so I've talked with Matt. A $620,000 letter of credit up front would make Mrs. Zwiers probably have to put in escrow at a bank $620,000 cash or, if its stocks and bonds, probably $800,000-$900,000 before banks can issue that letter. If we can do this in sequence of maybe a fifth of this or enough to cover each phase 110%... Sacchet: So you would like to do it in phases, sequencing it? Herbst: Yes, and the same with the trees. If we could do the trees, and if Jill could talk to the same people that I did today, too, and if we can make that kind of buy, that's a great buy for trees. ...in the future, that could get very costly if we were to have to put 38,000 trees out there. At the price of what I paid last year that could be a 1.9 million dollar deal. ...Hennepin Village. Sacchet: The last question Dan, ...(the tape was changed at this point)... stormwater. Can you give us a little bit more meat to that one? Herbst: I think most of its done except a tree survey but we have got a good stormwater plan worked out, we've got good contours for you, we've got a good storm pond system set up and I think the data that's on the site now is, we're light years ahead of where we were six months ago. Some other things we've got to do as we work on this plan with you is we've got to work out some access issues with MnDOT and that's another thing we haven't addressed. Sacchet: Alright. I think that's all the questions we have for you. Thank you very much for your presentation. This is a public hearing so I would like to invite anybody who wants to address this item, wants to add your view to it, any comments, please come forward. Any takers? Please state your name and address for the record please. 19 Planning Commission Meeting — August 17, 2004 Spiess: My name is Mike Spiess at 470 Flying Cloud Drive. Per the map I'm actually a little bit west of what they're proposing so a lot of my questions did get addressed; however, some of the things I'm hoping the applicant would be willing to do is keep us in mind when they are moving into the western part of that because it's going to, there's a lot of dust and stuff that will be kicked up. Ideally, there are things we can do as homeowners to limit the effects to our houses. I know I've talked to my other neighbors. We don't see this as a problem. We'd like to work with them however we can, asking that they keep us in mind, too because we are existing. We aren't part of what we currently see here but we are. One of the other questions I had is on the, I know they own a little bit more land than what is currently being proposed here. It's probably only another couple of acres possibly which would be directly in front of the three houses that aren't listed here. I'm just wondering if there is anything in place for that currently. If that's going to be part of this or not. There was something else but for the life of me I can't remember what it is right now. Sacchet: Kate, do you want to just address his concern, his question? Aanenson: Again, there are conditions for grading and we do have that in here. I was just checking with Matt on that too regarding hours of operation and there are standards as part of the interim use permit and that's why there are securities so those are enforced. As far as again, the overall grading, ultimately it is the City's goal as we update the City's Comprehensive Plan which has to be done in 2008, we did provide a phasing plan and we anticipate that this area will be coming in approximately 2015. But again, we kind of go back and re-examine that. We guided the rest of this area for industrial. There are some industrial uses along 212 and we want to make sure that there is adequate access based on our understanding that if 212 gets built, this would become a county road and we want to provide access. The county doesn't want every individual driveway so ultimately, everybody has benefited, not the exclusivity of one person. We would work through those issues as we're updating the Comprehensive Plan. We want to do a corridor study and look at how all these properties connected and link to each other as we provide municipal services which would be sewer and water and road access so that discussion will be coming up again. This plan doesn't propose any development now. We're just trying to fix some other issues. Spiess: OK. And that was my other question is this is strictly grading? This is nothing else at this point? Aanenson: That's correct. Any plan that would come forward requires a public hearing before the Planning Commission. Spiess: OK. That's all I had. Thank you very much. Sacchet: Anybody else who wants to address this item please come forward. State your name and address for the record please and let us hear what you have to say. Tester: I'm Dan Tester and I live at 230 Flying Cloud Drive. I'm one of these houses, this one right here, this is where I'm at. I've been in there almost 27 years and I realize that progress 20 Planning Commission Meeting — August 17, 2004 coming all over and I don't know, I guess I'm concerned as where my family is going to be with all this and what the plans are with my property and what's going to go on with that and also, with all the construction and stuff, I'm concerned with the quality of our living there. Our quality of our life while this is all going on too. Also, this pond here looks like its right in my driveway and I don't know how I'm going to get in and out of there. Anyways, I don't, it's been a quiet, nice neighborhood all these years or most of the years, not the last few, but I kind of hate to ... I wish it wasn't all happening. I would like to just live out the rest of my life there, get the place paid off and stay. I don't know. So anyways, I'm just concerned as to what's going to happen to my place, where we fit in. So anyways, I don't know what else to say. It's happening and it's kind of different experiences for us. Sacchet: Well, can we respond to that? Saam: I'll just suggest a couple of things and then Kate can add anything she wants. Two of our conditions were specifically meant for the two residences, the 230 and 240 residences. Access to their houses has to be provided at all times and we're talking about doing this in a phasing approach and what staff would envision is phasing plans that would show each phased approach and when he gets to the west side, if the Zwiers or Mr. Herbst doesn't have control of those properties, then those properties would have to be left out. The driveways will have to be shown how they're going to access off the proposed street or whatever so we won't forget about these residences. Sacchet: Kate, do you want to add anything? Aanenson: Part of the reason why we felt strongly about on the other side of the creek, that gives them a level of protection. The one -and -a -half acres that we talked about as we drove down that street, you can see that there is kind of a natural, topographic break, the creek and then the bluff rising up. Again, as Matt indicated, and everything behind this, if this property was not to be blended, the people on Erie, because ultimately this could be happening as one. If that doesn't happen, then we would make sure that the break was such that there's not such a severe, and obviously the stormwater pond couldn't go there. That would be phase one so I think one of the conditions that we, what we probably should put in here is that we evaluate each year kind of see where we're at as those phasing plans come forward and see if we are on task. And that would give them an opportunity, the homeowners, to see where they are and it sounds like there are some negotiations going on and we certainly would be happy to ... make sure they understand. Sacchet: OK. And I would expect that the creek area is something that we would try to preserve from every angle from the developer as well as from the City's side. Aanenson: Absolutely. Sacchet: It is not inconceivable that those properties could stay if it turns out that way. On the other hand, I'm sure there will be discussions and options explored as this moves forward. We are really not in a position to really answer your question, what's going to happen? Ultimately, you decide that because you're the property owner for that particular piece. I would expect that over time different options will become more clear as the phases come further that direction of 21 Planning Commission Meeting — August 17, 2004 the grading. In the meantime, you don't have the shooting next door anymore or the hauling and mining. You may have some grading. I'm not going to judge which one is better but I probably personally would know which one I prefer. The hearing is still open if anybody else wants to come forward and address this item, please do so. State your name and address for the record please. Ford: My name is Lonnie Ford. I live at 450 Flying Cloud Drive. I've only lived there for maybe three years now. My one concern is your flooding. When I moved in the river had flooded over and took out 212. You couldn't get at it. I can figure that it's still going to do that seeing how in 1965 it was way up here. Among all the wildlife issues that they've had listed for that area in the first place. This whole area that you're talking about was all deemed a wildlife refuge area. Is that null and void now? Aanenson: That area is not a wildlife... everything south of 212 is part of the wildlife refuge. It's on the south side of 212 and it's not the City's intention to provide any municipal services south of 212 because most of that is in the flood plain and this area here that would be developed, it would be above the bluff. Ford: It's clearly above. Are you having access only from 212 to these houses? Aanenson: That would be correct. Ford: And when 212 floods again, what are you going to do? Aanenson: It's the same situation that would happen... Ford: We don't have a problem getting to our homes. It's a little past that towards Lion's Tap I would say that it does flood out across 212, but that was only three years ago and the water level didn't get that high. I don't know if they called 1965 a 100 -year flood or not. I would consider that if it was going to flood again and a lot more than it did before, you are going to have some trouble. Aanenson: Sure. Again, right now the goal is to get the slope re-established and we're not looking at a development proposal but that's something, certainly as it moves forward, that we look at access points on that property. Ford: You're not drawing in a new road off of 4? Aanenson: Right now we're just using an access to get in there to mine and extract the material for this development proposal. Ford: That's my only questions. Sacchet: Thank you. It's a very good point that needs to be looked at. Anybody else want to address this item? If not, I'll close the public hearing. I thank you very much for all your 22 Planning Commission Meeting — August 17, 2004 comments and aspects of very good points you brought up. I appreciate it. Now I'll bring it back to the Commission for discussion and comments. Claybaugh: Well, certainly going out on site and reviewing the site personally, it's in dire straits of help, sooner being better. I think it's a responsible, measurable response and I'm very supportive. Sacchet: Thanks, Craig. Bethany, likewise? Tjornhom: Likewise. Except that I do want to add that I hope that as the City and developers work together they do whatever the neighbors and the homeowners during this whole process. Sacchet: Dan, anything to add? Keefe: I support the proposal. I just had a couple of questions. One is in regards to any DNR report. Would we add something like that as a condition to this in terms of any...? Aanenson: There is a 60 -day comment period. Anything that they would submit to us between now and when it goes to City Council we would certainly add that. Keefe: OK. In regards to the, I think number 30, which is the tree, the range ... I guess what we would be approving is that they are going to plant trees. Is there any more specificity around that? Sacchet: Well the condition asked for 20,000 trees..Jor 7 by 7 spacing. It's relatively specific. Aanenson: I think the clarity that the City Forester provided to the applicant was the size and species type and I think there is concurrence on that and what we were looking at is 6 to 8 inches. These are actually seedlings and that may be again put with tubes so they're protected. So I think there is concurrence on that and we gave them a price on that and I think it's significantly less than what they thought originally. Again, that breaks down based on what we can get at bulk from the DNR and they want us, this is a site that they've identified that they want to look at that... Keefe: There's a fair amount of discussion around phasing. Does that mean we would require in regards to paving or review or... Aanenson: I think you should add a condition. Saam: I do believe we tried to address that. Condition number 3. I'll just read it. It says, "The interim use permit shall be approved for a period of five (5) years from the date of City Council approval. Annually, the grading permit must be renewed. The applicant will need to request a formal extension 60 days prior to the expiration date of the permit." So what we were looking for, kind of proposing was that the entire plan would be approved by yourselves and Council and then staff would annually review a grading permit for the site unless you wanted to get into more detail. 23 Planning Commission Meeting — August 17, 2004 Sacchet: Does that address your phasing concern? Because I was wondering about that too, personally. Keefe: I think so. Claybaugh: I have a ... question. Sacchet: Go ahead, Craig. Claybaugh: What would you see being in terms of supporting documents for that application? Saam: Sure. It would be a phased grading plan, and interim grading plan for the area they're proposing to grade and work on say, next year, they would have to supply that plan. We would have to review it based on this plan and make sure it conforms. Claybaugh: At which point you could review how it would affect neighbors, haul routes, and so on and so forth. Aanenson: Exactly. Quantities to be moved, landscaping. I think if that's something that you wanted to put on a administrative or if you want to just see that for your edification we could include that in the packet so you could see what we've issued. Claybaugh: It sounds like number 3 would be satisfactory. Sacchet: Sounds good. Anything else, Dan? Keefe: No. Sacchet: There are a couple of things and I think we all touched on them to some extent. One aspect is the tree aspect which we can't really tack to this one. That's something that we'd have to look at more in detail when more granularity for the project comes about and the concern if the DNR has anything to say. To me personally I think it's important to establish how special the tree gulf is and where it is. Is it all being touched by this project? I think that's something that should be established before it goes to Council. The phasing, ideally I would like to know a little more about it. We all know we have to start somewhere and I think you have a clear vision in terms of the direction we're going in with and we feel comfortable with that. As a matter of fact, I think it's an excellent direction you're taking. The concern from the neighbor about the flooding I think is quite significant, even though it's clearly above the flooding plain where this grading and all would take place. But in terms of the access, if the flooding indeed could make that place landlocked. I think that's something that needs to be looked at in terms of how we deal with that. The neighbors' concern, those two properties, I would think that's something to work out over time. I don't know if from a City viewpoint we can get more involved with it except that we put some protection in there in terms of access and we saw we all have a common interest in preserving the natural area, especially around the creek there. I think that's how far we can go with that from a City viewpoint. In terms of the contamination, lead contamination FM Planning Commission Meeting — August 17, 2004 from the rifle range, I assume that's being covered by state regulations. That's not something we have to get involved as a City, is it? Aanenson: In the Phase I environmental audit of how their going to manage that. That was the other condition that... Sacchet: There is a condition for that in there? Which one is that? Saam: Condition number 5. Phase I environmental audit. That will shake out any contaminants... Sacchet: OK. That takes care of that. So the one that maybe I would like to add is the concern about establishing the tree line original growth there that needs to be looked at and I don't know whether we need to say something about the flooding of access but I think that would probably be worthwhile. I wanted to mention as something that needs to be studied. I don't think we would make it a condition but it's something that just to anchor it in that it's being looked at? Saam: Mr. Chair? Sacchet: Yes? Saam: I'm just writing down my notes. Staff, we'll take a look at 212 and those elevations. My guess or hunch is that if one and either the east side of 212 or the west side is flooded the other one was able to be passed because there are other residences around 212, not just on the south side but on the north and I guess I haven't heard of them being landlocked during, I think we flooded three years ago in 2001 so that's something... Sacchet: I think the comment of the resident was flooded further east if I understood correctly what you said so it was open to the west I presume based on what I heard you say. Ford: Yes. Sacchet: OK. Alright, so that helps. I think that's all the comments I have. I really support this. I think it's in very good hands. Very convincing presentation from the applicant's side. I want to thank you for that. With that, I'm willing to take a motion. Papke: I'll go ahead. The Planning Commission recommends approval of Interim Use Permit Planning Case #04-27 to permit grading, excavation and slope restoration as proposed on the plans prepared by Sathre-Bergquist, Inc., dated 7/16/04, subject to the following conditions as presented by staff 1 through 32. Sacchet: Actually, it's 3 through 32. Aanenson: Yes. Papke: Pardon me. It's 3 through 32. 25 Planning Commission Meeting — August 17, 2004 Sacchet: We have a motion. Is there a second? Keefe: Second. Sacchet: We have a second. Any friendly amendments? Papke: Friendly amendment. Sacchet: Go ahead, Kurt. Papke: Friendly amendment that we strike condition number 29 because it's redundant with condition number 16. Sacchet: That's acceptable. Abight. Any other friendly amendments? Do we want to have a friendly amendment that access concerns in view of flooding will be further studied? Papke: That's acceptable. Sacchet: And another friendly amendment that, how do we say that, further special concern will be given in case there is original growth established on the site. Papke: Kate, with that 60 -day review is that necessary? Aanenson: I guess the concern is that the DNR has additional comments that you may want to inject or did you want the Council to review those? Sacchet: Yes. That's kind of where I'm going with this. Aanenson: OK. So if the DNR does comment on any natural gulf areas you want those to be incorporated? Sacchet: Basically my intent is that question is cleared up before it goes to Council. That's really what I'm shooting for with this. Papke: If you find that necessary, it's acceptable. Sacchet: OK. So we have a motion, we have a second, we have some friendly amendments. Everybody in favor say aye. Opposed? Motion carries 5 to 0. Papke moved, Keefe seconded that the Planning Commission recommends approval of Interim Use Permit Planning Case #04-27 to permit grading, excavation and slope restoration as proposed on the plans prepared by Sathre-Bergquist, Inc., dated 7/16/04, subject to the following conditions: 26 Planning Commission Meeting — August 17, 2004 NOTE: The conditions in the staff report were incorrectly numbered 3-32 (original condition number shown below in parenthesis) but have been renumbered as 1-30. 1.

Sacchet: In summary for Council, I want to point out that we're very impressed with the applicant's vision and direction that he's taking with this. We believe this is in good hands. We went to look at the site and certainly appreciate the effort to start cleaning this up in a sensible good manner that is not just cleaning up but actually leading to what ultimately can become a very positive development for the future, a little ways out in the future. That's one of the aspects I personally have been most impressed with. To actually see how far this is thought through and then in how far the situation really reaches to become a really solid foundation for a good development at some point, not that far in the future but still decent ahead and that is also part of the value that we see that the natural environment can somewhat stabilize before that is going to take place with the significant slopes that have to be dealt with there. A very difficult challenging situation with extreme slopes, with extreme erosion, with contamination of lead, a lot of significant hurdles to overcome. We have some concerns about the impact on the natural environment but I think the applicant is very sensitive in terms of how this is being approached. The concern of the neighbors that live there in the middle, there are two properties in the middle, that's definitely something that needs to be considered, at this point kind of an exception. Whether it remains and exception or not, that's going to be up to those residents to decide. Certainly, the preservation of the creek area seems to be a common thing that everybody seems to agree that's important to maintain and we are comfortable with the aspect of phasing this in starting on the northeastern corner and then coming from the eastern side further towards the west. There is concern with exporting this huge amount, tremendously big amount of material in terms of if that's going to be affecting the traffic situation or if it's going to access 212 even with the consideration that 212 will off-loaded once the highway, the actual 212 highway is going to be built. That will certainly help. But even with that, it's an issue that needs to be looked at. A lot of these aspects will be addressed after we move forward and then see more what exactly is going to come about and we look forward to further discussion with the applicant on where this is going. Anybody want to add something to the summary? Claybaugh: I do. I would direct it to Kate. I don't know if it would be appropriate, but is there anything from the City's standpoint we can do to facilitate just in terms of the two neighbors O Planning Commission Meeting —August 17, 2004 specifically that they are duly communicated to rather... it's troubling to see someone come up and appear that blindsided. Sacchet: Yes. I think that's important that we anchor that in. I would expect that certainly the applicant will work with those neighbors as the whole region clearer. Claybaugh: I recognize that the applicant has an option and it's inappropriate perhaps for him to be communicating but there certainly needs to be something facilitated for those neighbors. Sacchet: Good comment, Craig. I appreciate that. Anybody else want to add any of the highlights to the summary for Council? No? OK. With that, I thank you very much. Good luck with your project. You want to add something? Herbst: Thank you very much for coming to the site and for the... deliberations. Are you open to some of the items we looked at... Sacchet: Yes. What I would encourage you is maybe set up with staff a discussion. We do that with developers at times. We have discussions where we can talk about... Herbst: But not get into it here. Sacchet: No. I would definitely not consider that issue. As a matter of fact, I'm personally not interested in... Thank you very much. Anybody want to note the minutes? APPROVAL OF MINUTES: Commissioner Tjomhom noted the verbatim and summary minutes of the Planning Commission meeting dated August 3, 2004 as presented. Sacchet: Minutes have been noted. Meeting has been adjourned. Thank you very much.

Schwalbe, Administrator Cell (952) 221-1089 We have previously mailed this letter of comments on the above referenced project. However, at that time we were unable to get board input due to the deadline. We are re -submitting the previous letter dated August 14, 2004 under the new date of August 31, 2004 and including the board's comments on page three. The Lower Minnesota River Watershed District (LMRWD) thanks you for the opportunity to review the Moon Valley Gravel Mine in Chanhassen. We are submitting a summary of our engineering review of the grading, drainage, and erosion control plan for the Moon Valley Gravel Mine located in Chanhassen, Minnesota. The plans that were reviewed included the grading, drainage, and erosion control plan dated July, 16, 2004, and a Stormwater Calculations report dated July 21, 2004. Both were prepared by the Sathre-Bergquist firm. Hydrology and water quantity related comments are as follows: 1. The curve number selection of 69 for existing conditions seems high given the sandy soils prevalent on the site. The curve number should be lowered to 61 to better reflect current site conditions. 2. The curve number selected for proposed land use conditions appears low. (CN=76) For clarity and to better model small storm runoff from the site, the proposed medium density/high density residential areas should be modeled separately from the overall watersheds, rather than lumping them together. This will assist in future reviews in determining if the proposed development is consistent with the current proposal. 3. Times of concentration used in the model from the sheetflow calculations appear to be too long, resulting in underestimated peak discharges. The Manning's "n" value used in the calculations Page I of 3 Scott County Government Center 2004 Ih Avenue West Shakopee, MN 55379 Phone: (952) 496-8842, Fax: (952) 496-8844 E-mail terrysWowernrn.cony Lower Minnesota River Watershed District corresponds to dense grass conditions, which are likely optimistic given the slopes of the site. A better estimate can be made using either short grass or unpaved conditions to be conservative, especially given the steep slopes on the project site. 4. Overall, the rate controls provided by the proposed ponds meets the 10 year and 100 year predevelopment discharge rates. However, it does not meet the 2 -year predevelopment discharge rate. This could be accommodated by installing a small orifice and overflow weir outlet control structure without drastically raising the high water levels from the 10 and 100 year events. Changes resulting from comments #1-3 may change these results. 5. Drainage to Pond 1 from a portion of WS -5P is not accounted for in the rate control calculations provided for Pond 1. Although this area is not proposed for development, runoff from this area will affect pond operation. Modeling of peak flows and rate control for the 2, 10, and 100 year events should be re-evaluated with a revised watershed for Pond 1. 6. Watershed WS -1 P does not have clearly defined drainage boundaries. Although it does not enter the portion of the site that is to be regarded, it will need to be better defined in order to quantify whether or not flooding will occur over TH212. 7. The proposed drainage diagram appears to show runoff from the Settlers West Development on top of the bluff draining to a concentrated point at the top of the proposed 2.5 :1 constructed slopes. These concentrated flows must be avoided and prevented in order to prevent severe erosion of the steep slopes. Runoff may need to be piped down the face of the slope at this location. 8. The west end of watershed WS -3P will naturally drain to the channel/wetland to the west, while the ultimate proposed plan indicates it will be directed east to Pond 2. Water quality treatment should be provided prior to discharging to the channel/wetland complex. A temporary sediment basin may need to be installed in this location until final development occurs and redirects runoff to Pond 2. 9. It is not clear how runoff from watershed WS -61P will be directed to the proposed Pond 1. The grading plans show sheet flow to the south, where it will intersect the proposed site access road. Based solely on contours, it appears runoff will sheefflow over the road and then will continue on to TH 212. Details regarding how water will be directed to Pond 1 should be included for review. 10. No details regarding the proposed pond outlets were submitted for review. At a minimum, they must provide skimming up to the 5 -year storm event. 11. The plans do not make it clear how runoff from watershed WS -51P leaves the site. High water levels at any proposed or current outlet may affect the high water levels in Pond 1. 12. The steep slopes proposed for the site (2.5H:1V) will require substantial efforts be placed on erosion control during construction and vegetation establishment. The site should be thoroughly reviewed for erosion control measures as the current single lines of silt fence shown on the plan are likely not enough given the height and length of the proposed slopes. Water quality related comments are as follows: 13. The stormwater ponds should be designed to achieve a 60% reduction in average annual phosphorus loads. No details regarding the proposed nutrient removal efficiency of the ponds were provided.

Pond 1 appears to have a wet volume of 0.71 acre-feet and a mean depth of 2.45 feet. The minimum recommended mean depth is 3 feet for a water quality pond, in order to prevent scour and re -suspension of captured sediment. In addition, at the LMRWD's Board of Manager's meeting held on August 18, 2004, the board made a motion of additional comments as follows: It was moved and seconded to: 1. Send the letter out with recommendations that the Pemton Land Company's plan be altered to meet these requirements laid out in the August 14, 2004 memorandum and Pemtom Land Company should reply to the District for each item in the memorandum. 2. Encourage the City of Chanhassen to work with us in the development of a mutually acceptable agreement to enforce the provisions of the LMRWD 509 Plan and express the expediency of getting the plan in place. If we can't reach a mutual agreement, then the LMRWD will be forced to adopt rules to enforce stormwater management within the City of Chanhassen, 3. We want to hear back from you that through your permitting process you have implemented these standards and if not, why not, and have them send us a copy of the final permit with a plan or conditions adopted.

Prior to that meeting and recommendation, members of the Staff and Planning Commission conducted a field trip to the Moon Valley site and viewed the effects of mining over seventy years. The application we submitted provides for 18.4 acres of useable land out of a total of 70 acres. The City Council had great foresight by recommending high-density housing/office/commercial for this location in the Comprehensive Plan. Although the site speaks little to a high quality mix use development today, the future for this site and for the city is truly bright. I asked the Planning Commission to challenge the quality of the trees that exist on the site and the artificial bluff created by mining and to not compare the reuse of this land to a typical development on native terrain. We discussed how the City of Edina became actively involved in the acquisition and development of the Hedberg gravel and concrete operation that is now the home of the magnificent mixed use of Centennial Lakes and Edinborough. This project is considered one of the premiere mixed uses in our country consisting of office, theater, retail, restaurants, and many alternative housing lifestyles surrounding a lake, fountains, parks, and trails. Even though we are only requesting approval of our current application, we ask you, as we asked the Planning Staff and Commission, to think outside of the box and to envision a much larger use exceeding 25 acres or more. After the restoration of the site is completed according to the terms and conditions of your approval, we would like to come before you at a future date with concepts that would greatly expand the amount of land to be used and allow a fulfillment of the City's Comprehensive Plan. I have attached some talking points that I presented to the Planning Commission on August 17, 2004 and a copy of the Urban Land Institute's article on Edinborough and Centennial Lakes. Honorable Mayor, Members of the City Council, and Professional Staff September 27, 2004 Page 2 We respectfully request the approval of the submitted interim use permit.

The Contamination Cleanup Grant Program was created by the legislature in 1993 to provide funds for cleaning contaminated sites. The Program was amended in 1997 to allow DEED to grant funds for contamination investigation and RAP development. The investigation grant funds are intended to jump-start the environmental remediation process so that properties believed to be polluted can be cleaned and redeveloped. APPLICATION DEADLINES: The Contamination Investigation and RAP Development Grant Program operates on a semiannual grant cycle in conjunction with the Contamination Cleanup Grant Program. Deadlines for making application are November 1 and May 1 of each year. Complete applications must be received at DEED by 4 p.m. on either date. In the event that these days fall on a weekend, the deadline will be the following business day. You must submit the original application and 2 copies. NOTE: If you are applying for investigation funds for more than one site, a separate application must be completed for each site. FUNDING AVAILABILITY: Up to $500,000 of the total $16.7 Million available for the Contamination Cleanup Grant Program for the 2004 - 2005 biennium is available for investigation and RAP development grants. ELIGIBLE COSTS: The legislation allows DEED to award grants for up to $50,000, or 75% of the total investigation cost, whichever is less, for investigating for contaminants and developing a RAP. No more than $250,000 per fiscal year may be awarded for investigation grants. Applicants may be at the beginning of the investigation process and apply for all investigation and RAP development costs up -front. Or, if an applicant has completed and financed a portion of the investigation on their own, they may apply for reimbursement of the incurred and financed costs along request for the remainder of the investigation and RAP development costs. If the entire investigation is complete, you should not apply through the investigation program but may apply for cleanup funds if site cleanup is necessary. LOCAL MATCH REQUIREMENT: The applicant must pay for at least one-quarter of the total estimated investigation costs as a local match. At least twelve percent of the local match must come from unrestricted funding sources. Investigation FY 04 - FY 05 ELIGIBLE APPLICANTS: Eligible applicants include statutory or home rule charter cities, counties, housing and redevelopment authorities, economic development authorities, and port authorities. (Note: A site may be publicly or privately owned.) QUALITY SITE ASSESSMENTS: Applicants must work with the Minnesota Pollution Control Agency (MPCA) in assessing the site and developing a RAP. Requiring applicants to follow the MPCA investigation and RAP development guidelines ensures that the state is paying for quality site assessments and allows the applicant to qualify for a Contamination Cleanup Grant (which requires an approved RAP from the MPCA). The MPCA has guidance documents and fact sheets available for performing investigations. The guidance documents should be followed throughout the investigation and RAP development process. For more information or to get copies of these documents you may contact the MPCA at 651-296-7291. QUALIFYING SITES: A site qualifies for a Contamination Investigation and RAP Development Grant if the following criteria are met: 1) If you are an applicant from the Twin Cities Metropolitan Area, your municipality must be participating in the Metropolitan Council's Local Housing Incentives Program. For more information on this program, call Guy Peterson at 651-602-1418. 2) It is expected that the site will be improved with building or other improvements. If the investigation identifies the need to remediate, it is expected that cleanup will be accomplished so that the site can be developed. The improvements should provide public benefit such as a tax base increase, new jobs, or other public benefits. Final development of polluted sites could include, for example, commercial, industrial, office or housing development. Housing developments should include an affordability component. There should either be affordable units on the site, or units committed to another site within the applicant's jurisdiction. Housing developments that do not include any affordable units (on- or off- site) may not be considered for funding under this program. "Affordability" is defined using U.S. Housing and Urban Development and/or Metropolitan Council standards, determined by the municipality. GRANT AWARD CRITERIA: The law directs DEED to make grants for sites that provide the highest return in public benefits for the public costs incurred. In order to evaluate the applications for public benefits with respect to the costs incurred, the law further specifies priorities which DEED must consider. The legislative priorities listed below have been assigned maximum point values in order to systematically award grants in each cycle: MPCA review of the potential threat to human health and the environment that would be reduced or eliminated by investigation and cleanup. Maximum = 30 points. 2. The social value to the community that will result from testing, cleaning, and redeveloping the site. Social value includes the time frame, the number of new and retained jobs, the importance of the proposed public facilities, the removal of blighting influences at the site, the readiness of the project, the development potential and the financial health of the project. Maximum = 55 points. Investigation 111 FY 04 -FY 05 3. The potential increase in the property tax base of the local taxing jurisdiction. Maximum = 30 points. 4. The probability that the site will be investigated for contamination without the use of government money. Maximum = 10 points. The amount of investigation costs for the site. Maximum = 10 points. 6. The amount of the commitment of the municipality or other local resources to pay for part of the investigation costs. Maximum =10 points.

Attach an accurate and legible site and location map that shows: a) The current condition of the site including labeled structures; b) The proposed development of the site including labeled structures; and c) The suspected location(s) of contamination. See Attachment A - also includes land use and planning maps. Please attach photographs, in addition to maps, if they are available. 7. Acreage of Site 39.8 Sq. Ft. of Site 1,733,695 8. Zoning/Land use: A. Current: Industrial_ Commercial Residential Mixed use Other (specify) X (Agricultural)_ B. What the is expected zoning/land use after investigation and cleanup: Industrial Commercial _ _ Residential X Mixed Use X Other (specify) The Property is an integral part of several properties that will be developed concurrently as part of an overall development plan. A property to the southwest, also owned by Zweirs has been proposed for commerciallresidential development by Pemtom Land Company and is included in the discussion of the development plans for the Property. The total project will be approximately 75 acres, including 43 acres of open landlsceniclbluff/recreational. Of the 32 acres developed, 25 acres will be a mixture of low and high density housing with 7 acres reserved for integrated office/retail. 9. Current economic condition: Vacant lot X Developed site_ (explain below) 10. If the site is currently developed with unoccupied buildings, how long have the buildings been vacant? Approximately 15 years 11. Please describe the condition of any buildings on the Site? Most of the site is undeveloped mine land, several structures related to gun range and mining are still present. A. The old house was built in 1956 and is dilapidated, structurally failing, and will need to be Investigation FY 04—FY os abated and demolished B. Gun range office and firing house are non -domicile shelters with post and 2x4 construction C. The scale house is a mobile home trailer that can be removed from the site. D. Fugitive dumping and miscellaneous semi -truck trailers are stored on the Property along US 212. This area will also require some investigation and clean up. 12. Please describe how Site redevelopment will spur adjacent development? The former gun range and mine are currently a source of erosion and blight. The increase in high-density residential housing will support the local tax base and invigorate existing and proposed new business along Flying Cloud Drive. The residential development on the Property has been proposed as part of comprehensive mixed use development including a new business commercial corridor west of the site. The actual development of the property will not occur until sewer and water are connected at the site, however, the schedule for sewer and water can be moved up if the clean up is completed sooner. It is critical that investigation and clean up begin early because the slope restoration and grading of the site will require five years before development can begin. This is because the engineering estimates call for over 1,000,000 cubic yards of fill to be removed from the site. This large volume of soil will require several years to be trucked off of the site. In order to begin removing the soil, each area of the site must be investigated and cleaned up. An interim use permit has been approved by the Chanhassen City Council as the first part of future development. Future phases of development cannot be finalized until appropriate approvals are granted by the City of Chanhassen. A copy of the Interim Use Permit Letter is included as Attachment B. II. SITE HISTORY 13. Please attach a brief synopsis on the history and general background of this site. This includes but is not limited to former uses and occupants of the site, suspected causes of contamination, etc. Also describe the current condition of the site and include a description of existing structures and existing occupants of the site. See Attachment C. III. CONTAMINATION INVESTIGATION INFORMATION 14. Current status of the investigation. A. Is the site enrolled in the MPCA VIC Program? Yes B. Has a Phase I Environmental Site Assessment been completed? No — A Phase I is in progress; as required by the Interim Use Permit (Attachment B) general a site reconnaissance and preliminary site investigation have been completed to focus specifically on the lead issue on portions of the Property that are likely to have negligible impact from past shooting on the Property. Reports are included in Attachment D. If so, attach a copy of the Phase I to this report. investigation FY oa —FY 05 C. Do you have an approved work plan to begin implementation of a Phase II? No D. Has any of the work plan been implemented? No E. Please provide copies of any approval and/or comment letters you have received from the MPCA VIC Program and also provide copies of any reports documenting investigation activities that have been conducted at the site to date. 15. If any soil or water samples have already been collected, briefly summarize the identified contamination at the site to date (identified compounds, concentration, etc.). Also summarize the objective of the future planned investigation. Soil lead concentrations were detected at 680 mg/kg in one sample located near the trap range above the Tier 1 SRV of 400 mg/kg. Other samples within the shotfall zone are below Tier I SRV criteria. Future investigation will collect more datafrom near the firing line of the trap range, the backstop berms of the rifle ranges, and near sedimentation ponds and basins that collect runoff from these areas. Some groundwater investigation will be required due to evidence of sandy (permeable) soil and shallow groundwater near the base of the bluff nearest to the Minnesota River Wildlife Refuge. The goal of investigation is to assess impact on human health and the environment as well as to define areas of potential lead and other contamination so that appropriate clean up strategy can be employed. At this stage it is believed that some lead recycling and other metal recovery will be possible. Otherwise, excavation combined with off-site disposal and on-site stabilization are treatment methods that are often utilized for small -arms firing range (SAFR) sites. Due to the nature and distribution of lead discharged at the Trap Range, the potential area of impact is large and there will be a significant quantity of soil sampling required to reliably assess environmental risk as well as engineering needs. IV. COST ANALYSIS BUDGET 16. What are the total investigation and RAP development costs? $116,200 Due to the large area of the site that requires investigation, the total costs of the project are likely to far exceed the budget shown below for DEED committed funds. The DEED Grant budget request has been allocated to the largest portion of the project expense, which is for the Phase II Investigation. 17. How much are you requesting from DEED? ('Phis amount cannot exceed $50,000 or 75% of the total cost, whichever is less.) 50,000 Complete the budget table below. If you have already completed a Phase I investigation, you may include that cost in your budget in addition to the future investigation & RAP development costs to be incurred.

Are any costs listed in this budget eligible for funding from other funding sources? Yes 19. If any of the activities listed above are partially or fully completed, how were those activities financed? Owner (Zwiers) FINANCING 20. Please submit an audit, or financial statement if an audit is not available, from the municipality in which the site is located. 21. Is there a possibility that the site will be cleaned up without DEED money? _X_ Yes —No Explain your above yes or no answer. The property owner has agreed to conduct investigation and clean up actions that are economically justified for the Site. As with many properties, the minimum cost threshold for investigation and clean up is to bring soil concentrations down to levels consistent with the current land use (in this case mining/gun range). However, this level of cleanup would not be suitable for residential land use. With the DEED grant, the investigation and clean up can be expanded to accommodate a land use and development plan that will have a significant positive societal and economic impact for the community. Without DEED assistance, there are barriers to development that may result in less desirable land use and/or less favorable development plans. V. SITE VALUE 22. What is the current assessed value of the site? $ 688,000 Investigation FY 04 -FY 05 23. What is the estimated assessed value of the site should contamination be found and remediation completed? $ 688.000 There is no evidence that the current assessed value includes a reduction for environmental impairment. What is the estimated assessed value of the site after redevelopment? $ $6,000,000 A. How were these figures determined? Current data from Carver County Assessor and the purchase offer price from Pemtom Land Company is assumed to be the developed site value in the first year after redevelopment. After that, the sold units will contribute to the total taxable property base. B. Who determined them? Compiled by James Aiken (McCain) from the sources indicated above. VI. REDEVELOPMENT POTENTIAL 24. Explain the likely use of the site after investigation and cleanup. The Property is a key piece of a broader development strategy proposed for the 212 corridor along the Minnesota River. Since the development plan is predicated upon the availability of the Property for development, the financial aspects for the entire project is described herein. The land use will be mixed use with residential and office/retail opportunities. The project will be modeled after the existing Hennepin Village project by the same developer and located in Eden Prairie. Key elements will include a diverse mixture of affordable and market housing combined into a transit friendly, affordable community along a major collector road. A unique element of the development will be the availability of affordable housing in a bluff view setting that is that is typically only available to the upper -end market. Additionally, the proximity to the Minnesota Wildlife Refuge, the development provides a well-connected green belt and for recreation and wild life habitat. The Property will increase the acreage of undeveloped scenic bluff propedy, connect the Richard T. Anderson Conservation Area to the east to the LRT/Regional Trail and Outlot G of the Settler's West Subdivision to the north. 25. If the site will be redeveloped for residential use, provide the following data: TOTAL # OF RENTAL UNITS TO BE DEVELOPED Monthly rental cost per unit $ Number of affordable units Construction cost per unit $ Current market for rental units indicates that this will not be a primary goal of the project.

These opportunities require that adequate land be designated for medium and high density land uses. The city will seek to discourage the conversion of these areas to lower density uses to ensure that the goal of housing diversity can be met regardless of temporary market fluctuations. Housing Action Plan The city will continue to uphold the housing goals and policies of the comprehensive plan. In addition, the city will pursue other resources for providing life -cycle and affordable housing. Policies As state and federal funding permits, efforts should be made to provide low and moderate housing where needed, to provide balance to the generally high cost of new housing. New construction programs may provide a source of such housing. The city should promote the use of state and federal programs designed to reduce land costs for developers of low and moderate income housing. Natural Resources Groundwater Protection The City has been actively involved in the removal of leaking underground storage tanks and the treatment of contaminated soils that result. The City has undertaken this on several properties that were subject to redevelopment activities has cooperatively worked with private individuals who have encountered such problems. It is anticipated that these efforts will continue. Policies Develop plans and ordinances designed to protect the Minnesota River corridor taking the old Hwy. 212/169 route into consideration. Work with the U. S. Fish and Wildlife Service and Minnesota Department of Natural Resources to expand, protect and promote utilization of the resource by Chanhassen residents. Encourage and assist businesses, organizations, and private citizens in their efforts to beautify and otherwise enhance the environment. Continue to follow the recommendations outlined in the Surface Water Management Plan; providing 100 -year flood protection for all persons and property, protect and improve water quality within Chanhassen lakes, streams, wetlands, and in the Minnesota River by mitigating both point and non -point sources of water pollution and to protect and rehabilitate wetlands to maintain or improve their function and value. Work for approval of a Comprehensive Wetland Management plan for state approval. Once the plan is in place, follow recommendations for the reclassification and improvement of Ag/urban wetlands. o y- z7 4:4 MEMORANDUM TO: Todd Gerhardt, City Manager CITYOF FROM: Kate Aanenson AICP, Community Development Director CHANIIASSEN DATE: May 23, 2005 7700 Market Boulevard — y/ PO Bos 147 SUBJ: Moon Valley Contamination Clean-up Grant Chanhassen, MN 55317 Administration Phone: 952.227.1100 BACKGROUND Fax: 952.227.1110 Building Inspections On September 27, 2004 the City Council approved the Interim Use Permit for Phone: 952.227.1180 Moon Valley.

Legal description of the site: Government Lot 1, excluding 5.95 acres south of northerly right of way for Highway 2121169 in Section 36, Township 116N, Range 23 West, Carver County. 6. Attach an accurate and legible site and location map that shows: (Appendix A Figure 1,2)) a) The current condition of the site including labeled structures; (App A. Figure 3) b) The proposed development of the site including labeled structures; and (A. Figure 4) c) The suspected location(s) of contamination. (App A, Figure 5) See Attachment A — also includes land use and planning maps. Please attach photographs, in addition to maps, if they are available. 7. Acreage of Site 39.8 Sq. Ft. of Site 1.733.688 8. Zoning/Land use: A. Current: Industrial_ Commercial Residential Mixed use Other (specify)X (Agricultural)_ The site is currently operated as a mine and former gun range as a non -conforming pre-existing land use. B. What is the expected zoning/land use after investigation and cleanup: Industrial Commercial _ _ Residential X Mixed Use Other (specify) Of the 39.8 acres on the Site, approximately 15 acres will be developed for residential use consisting of about 225 high-density condominiums or town homes. The remaining 24.8 acres will be reserved as open space and protected scenic bluff under City Ordinance. The Site is the cornerstone of a development that will be conducted jointly on several properties within the overall development plan. The property to the southwest, including portions that are also owned by Zweirs, has been proposed for commerciaLlresidential development by Pemtom Land Company (Attachment E). Because this development will likely not be feasible without the Site as its centerpiece, the overall plan is included, but described separately from the Site in the discussion of the development plans for the Property. The total project will be approximately 75 acres, including 43 acres of open land, scenic bluff, and recreational land use. Of the 32 acres developed, 25 acres will be a mixture of low and high density housing with 7 acres reserved for integrated office/retail. The total number of residential units will be 375. 9. Current economic condition: Vacant lot X Developed site (explain below) Investigation 4 FY 04 -FY 05 10. If the site is currently developed with unoccupied buildings, how long have the buildings been vacant? Approximately 15 years 11. Please describe the condition of any buildings on the Site? Most of the site is undeveloped mine land, several structures related to gun range and mining are still present. A. The old house and former ski chalet was built in 1956 and is dilapidated, structurally failing, and will need to be abated and demolished B. Worker trailer in parking lot is dilapidated and will be abated and demolished. B. Gun range office and firing house are non -domicile shelters with post and 2x4 construction C The scale house is a mobile home trailer that can be removed from the site. D. Fugitive dumping and miscellaneous semi -truck trailers are stored on the Property along US Highway 212. These areas/buildings will be included in the investigation and clean up. 12. Please describe how Site redevelopment will spur adjacent development? The former gun range and mine are currently a source of erosion and blight. The erosion from the former mine face, the former gun ranges, and various soil stockpiles, is a potential risk to surface water in an ecologically sensitive area (near the Minnesota Valley National Wildlife Refuge). The bare ground surfaces, abandoned structures, fugitive dumping and debris also present an eyesore that discourages local development and investment. The proposed development will include a mixture of affordable and market rate residential housing that will support the local tax base and invigorate both existing business along Flying Cloud Drive as well as spur investment and jobs to support the new residential base. The current and future commercial districts are shown on Figures 6 and 7 of Attachment A. Business in the adjacent communities of Eden Prairie, Shakopee, and Chaska will also benefit from the influx of new customers from the residential development at the Site. The residential development on the Property has been proposed as part of comprehensive mixed use development including a new business commercial corridor west of the site. The actual development of the property will not occur until sewer and water are connected at the site, however, the schedule for sewer and water can be moved up if the clean up is completed sooner. It is critical that investigation and clean up begin now because the slope restoration and grading of the site will require at least five years before development can begin. This is because the engineering estimates call for over 1,000,000 cubic yards of fill to be removed from the site. This large volume of soil will require at least five years to be trucked off of the site. In order to begin removing the soil, each area of the site must be investigated and cleaned up. An interim use permit has been approved by the Chanhassen City Council as the first part of future development. Future phases of development cannot be finalized until appropriate approvals are granted by the City of Chanhassen and the MPCA. A copy of the Interim Use Permit Letter is included as Attachment B. II. SITE HISTORY Investigation 0 0 FY 04—FY 05 13. Please attach a brief synopsis on the history and general background of this site. This includess but is not limited to former uses and occupants of the site, suspected causes of contamination, etc. Also describe the current condition of the site and include a description of existing structures and existing occupants of the site. A summary of the Site history is included in Attachment C. III. CONTAMINATION INVESTIGATION INFORMATION 14. Current status of the investigation. A. Is the site enrolled in the MPCA VIC Program? B. Has a Phase I Environmental Site Assessment been completed? Yes. A copy is included in Attachment D along with the Preliminary Site Investigation (PSI). The PSU was conducted to facilitate immediate erosion control on the Upper Mine Slope and transfer of Outlot G to the City of Chanhassen, and obtain letter of assurance under the VIC program. Copies of the MPCA letters to MVA and the City of Chanhassen are also included in Attachment D. The investigations indicate that severalacres of the site may be impacted by lead above the Tier I SRV value of 400 mg/kg. Also, erosion from areas of anticipated high lead concentrations (e.g. backstop berms) has moved soils down slope. Therefore, extensive sampling will be required to assess the extent and magnitude of lead contamination. The sandy soils and shallow groundwater at the downgradient edge of the property also indicate that groundwater and surface water quality must be assessed. In addition, there are old buildings that may have asbestos and lead, there are above ground storage tanks, fugitive dumping, several partially buried drums, and stockpile areas of lime sludge and construction debris that will be investigated. If so, attach a copy of the Phase I to this report. C. Do you have an approved work plan to begin implementation of a Phase II? No D. Has any of the work plan been implemented? No E. Please provide copies of any approval and/or comment letters you have received from the MPCA VIC Program and also provide copies of any reports documenting investigation activities that have been conducted at the site to date. (See Attachment D) 15. If any soil or water samples have already been collected, briefly summarize the identified contamination at the site to date (identified compounds, concentration, etc.). Also summarize the objective of the future planned investigation. Soil lead concentrations were detected at 680 mg/kg in one sample located near the trap range above the Tier] SRV of 400 mg/kg. Other samples from the northern and eastern edges of the shotfall zone are below Tier 1 SRV criteria Future investigation will collect more data from near the firing line of the trap range, the maximum accumulation zone, the backstop berms of the rifle ranges, and near sedimentation lnve tigatim 0 FY 04 -FY 05 0 ponds and basins that collect runoff from these areas. In accordance with MPCA guidelines this will require over 100 near -surface soil samples for metals parameters. Up to 10 deep (50 to 100 feet) soil borings are proposed to assess the quality and soil conditions at the final grade elevations proposed for the development. Groundwater investigation may be required due to evidence of sandy (permeable) soil and shallow groundwater near the base of the bluff nearest to the Minnesota River Wildlife Refuge. A goal of the investigation is to assess impact on human health and the environment as well as to define areas of potential lead and other contamination so that appropriate lead recycling/clean up strategy can be employed. It is believed that some lead recycling and other metal recovery will be possible in the pistol and rifle ranges where there is approximately 50% of the soil surface is composed of lead slugs and or bullet fragments. Another goal of the investigation is to collect sufficiently detailed data that will allow for cost- effective soil separation and recycling. Recycling of the lead rather than landfilling is consistent with Carver County and SWHCB strategic solid waste management objectives. The investigation will also provide information that will be used to guide excavation and potential corrective actions. Because off-site disposal and on-site stabilization are often utilized for small -arms firing range (SAFR) sites, investigation sample frequency must be sufficient to accurately identify contaminated areas and avoid treatment and disposal of clean soil. Due to the nature and distribution of lead discharged at the Trap Range, the potential area of impact is large and there will be a significant quantity of soil sampling required to reliably assess environmental risk as well as engineering needs. IV. COST ANALYSIS BUDGET 16. What are the total investigation and RAP development costs? $122,200 Due to the large area of the site that requires investigation, the total costs of the project are likely to far exceed the amount of the requested DEED -committed funds. The DEED Grant budget request has been allocated to the largest portion of the project expense, which is for the Phase H Investigation. 17. How much are you requesting from DEED? (This amount cannot exceed $50,000 or 75% of the total cost, whichever is less.) $ 50,000 BUDGET SOURCES & USES Eligible Activities for Investigation and RAP Development % Complete Date(s) Completed mnvyy DEED Request+ Local Match # 1 TBD_+ Local Match # 2 TBD= Total Phase I ESA 100 11/04 0 0 0 4,000 Preliminary Site Investigation 100 10/6/04 0 0 0 15,000 Phase II Work Plan 20 0 0 0 5,000 Kase H Investigation/Report 0 50,000 6250 6250 62;500 Owner -funded Phase II Remainder 0 0 0 0 28,500 FS/RAP Development 0 0 0 0 7,200 Total - Investigation & RAP Development: $122,200 18. Are any costs listed in this budget eligible for funding from other funding sources? Yes tnvmfigation 0 FY 04 -FY 05 0 19. If any of the activities listed above are partially or fully completed, how were those activities financed? The preliminary site investigation and Phase I ESA were financed directly by the Property owner (Zwiers) in order to initiate filling of the Upper Mine Slope and donation of Outlot G to the City of Chanhassen. I VzF410[ [!1 20. Please submit an audit, or financial statement if an audit is not available, from the municipality in which the site is located. Audit information has been provided to DEED from the City of Chanhassen. 21. Is there a possibility that the site will be cleaned up without DEED money? _X_ Yes —No Explain your above yes or no answer. Eventually the site will be developed, but without some funding the site is likely to continue to languish. The location and proximity to the Metro area would suggest that the Site would eventually be developed because of the location and the eventual addition of sewer and water service. However, the contamination and amount of earthwork required presents a significant economic barrier to development. The property owner has agreed to conduct investigation and clean up actions that are economically justified for the Site. As with many properties, the minimum cost threshold for investigation and clean up is to remediate soil down to levels consistent with the current land use. In this case, the current land use is essentially industrial due to the pre-existing (non -conforming) use as a mine pit/gun range. An industrial(commercial level of cleanup would not be suitable for residential land use and the proposed development plan. With the DEED grant, the investigation and clean up can be expanded to accommodate a land use and development plan that will have a significant positive environmental, societal, and economic impact for the community. Without DEED assistance, there are barriers to development that may defer development into the next decade and result in less desirable land use and/or less favorable development plans. V. SITE VALUE 22. What is the current assessed value of the site? $ 818,000 23. What is the estimated assessed value of the site should contamination be found and remediation completed? $ 818,000 There is no available evidence that the current assessed value includes a reduction for environmental impairment. What is the estimated assessed value of the site after redevelopment? $ $6,000.000 A. How were these figures determined? Current data from the Carver County Assessor's Office; the purchase offer price from Pemtom Land Company is assumed to be the developed site value in the first year after redevelopment. After that, the sold units will contribute to the total taxable property Investigation 0 FY 04 -FY 05 base. 0 B. Who determined them? Compiled by James Aiken (McCain) from the sources indicated above. VI. REDEVELOPMENT POTENTIAL 24. Explain the likely use of the site after investigation and cleanup. The Property is a key piece of a broader development strategy proposed for the U.S. Highway 212 corridor along the Minnesota River. Since the development plan is predicated upon the availability of the Property for development, the financial aspects for the entire project as well as the Site are described herein. The land use on the Site will be high- density residential, the larger project will be mixed use with residential and office/retail opportunities. The overall project will be modeled after the existing Hennepin Village project by the same developer and located in Eden Prairie. Key elements will include a diverse mixture of affordable and market housing combined into a transit friendly, affordable community along a major collector road. A unique element of the development (particularly at the Site) will be the availability of affordable housing in a bluff view setting that is that is typically only available to the upper -end market. Additionally, the proximity to the Minnesota Valley National Wildlife Refuge will provide a well- connected wild life habitat corridor and recreational opportunities. The Property will actually increase the acreage of undeveloped scenic bluff property, and connect the Richard T. Anderson Conservation Area to the east to the LRT/Regional Trail and Outlot G of the Settler's West Subdivision to the north. The proximity to these highly desirable natural features provides significant investment incentive for business to support the development. The Site itself would be the residential anchor of the development with approximately 15 developable acres and about 225 units. 25. If the site will be redeveloped for residential use, provide the following data: TOTAL # OF RENTAL UNITS TO BE DEVELOPED Monthly rental cost per unit $ Number of affordable units Construction cost per unit $ Current market for rental units indicates that this will not be a primary goal of the project. TOTAL # OF OWNER -OCCUPIED UNITS TO BE DEVELOPED 225 (on Site) 375 (total) Purchase price per unit/home $175,000 $300,000 Number of affordable units/homes 34 @ $175,000 to $193,700 Construction cost per unit: $145,00i to $220,000 Av-raze)_ * Housing developments should include an affordability component. According to Met Council (Guy Peterson), homes that cost $193,700 or less in 2004 were considered "affordable." The City of Investigation 0 FY 04 - FY 05 0 Chanhassen also has other development areas that meet this affordability component. 26. What are the current property taxes on the site? $16,636 27. What are the projected property taxes for the site when the site is cleaned and developed? According to the Carver County Auditor's Office (952)-361-1960 estimated that the 2004 property tax on a $220,000 homesteaded property located at the Site would be $3080 per unit. Assuming that there would be 225 units on site the tax would be $693,000. The increase in property tax revenue would be about $675,000 per year. For the entire project, the property tax revenue would be $1,155,000. JOB CREATION & RETENTION 28. Project the number of new full-time jobs that will be created after cleanup and development of the site. Total New Jobs: On Site: 0 Total development: 29 The Site will be used for residential, so there is no job creation anticipated on Site. However, as previously noted, the Site is the centerpiece of a larger development plan that will create new jobs and business opportunity. Using the Hennepin Village development (Attachment E) as a guide, the development might include a gas/convenience store, three general retail businesses, a retaiUmedical office, a bank branch office, and a fast food restaurant. The following assume that I full time and three to four part-time positions are created for each operation. Additional staffing needs are not included as these positions may be filled with transfers from other locations. NEW JOBS TABLE Position Title Total # of Full -Time Jobs Total # of Part- Time Jobs Annual Wage per Job Expected Hiring Date Retail/Office 3 9 40,000 2009 Medical Office 1 3 50,000 2009 Bank 1 3 45,000 2009 Gas/Convenience 1 3 35,000 2009 Fast Food 1 4 35,000 2009 29.

All voted in favor and the motion carried unanimously with a vote of 4 to 0. E. APPROVAL OF MODIFICATION TO THE CURRY FARMS PARK MASTER PLAN. Councilman Lundquist: Thank you Mr. Mayor. I had a brief discussion with Mr. Gerhardt this afternoon and just wanted to put that out on the public record as we have over the past year or so talked about ballfields in the city. This is one where it may appear on the surface that we're taking a playground structure and putting it over the top of a ballfield and just wanted to have Mr. Gerhardt go through his explanation that he walked me through today to talk about the practicality that this ballfield is actually, can be used widely and that this actually would be a better use for it at this park overall than the way it's slated right now. Todd Gerhardt: We also have our Park and Rec Director, Todd Hoffman here. He might be a little better served in explaining his report. Todd, what I talked about this afternoon was the elimination of that park and how we have not scheduled practices in that area. You want to go about your policy and field usage. Todd Hoffman: Sure, thank you. Mayor, members of the council. Curry Farms Park is a neighborhood park and we do not schedule practices in this location. The ballfield, you're actually correct. We don't want to go backwards in ballfield construction or maintenance in our city, but in this particular case we have an opportunity to really improve the overall master plan for Curry Farms Park. The ballfield is in a remote location. Somewhat wet and the playground that's currently situated on your plan. Right now in it's current location is at the bottom of a sliding hill used by the neighborhood and does not allow for a run out at the bottom of the sliding hill. These other things that you're seeing changed on the plan, we eliminated a trail section because of the wet terrain. This basketball court actually is over here. This playground, we want to move it on top of the ballfield. Eliminate the ballfield and then just leave it green space. Currently in all of our neighborhoods, new neighborhood park plans we do not include ballfields. The maintenance is just too excessive. We just plan for a green field. Open green field for the kids to play on. Softball, soccer or other play field activities, so in this case we're taking away the baseball but it's not heavily used at the current time. Councilman Lundquist: Todd, can you talk about the other structures that are nearby, the ponds and other things, the short fence and all those things that collect foul balls in the pond instead of staying in the field of play so to speak. Todd Hoffman: Absolutely. Curry Farms Park is, it's nickname is Sinking Park. We have a sink hole currently in this location. Thank you. This area of the park is sinking and so if you hit into the right foul line of the ballfield you're going to be in a swamp currently. 2 • • 6 `f 2-7 CITY OF CHANHASSEN CARVER AND HENNEPIN COUNTIES, MINNESOTA DATE: May 23, 2005 RESOLUTION NO: 2005-U MOTION BY: Lundquist SECONDED BY: Peterson RESOLUTION APPROVING THE CONTAMINATION CLEANUP GRANT APPLICATION AND COMNHTTING LOCAL MATCH AND AUTHORIZING CONTRACT SIGNATURE FOR MOON VALLEY ENVIRONMENTAL CLEANUP BE kT RESOLVED by the City Council of the City of Chanhassen as follows: 1.

We put down silt fence last week, but had some weather delays until Monday. We completed the lead screening in the rifle range berms on Tuesday and started excavating and stockpiling soils for the rifle and pistol ranges. I would say that we recovered about a ton of lead. The first test results from the floor of the rifle range should be back tomorrow morning. We have not started stabilization of the berm soils or excavation of the trap ranges yet. Should get to those tomorrow weather permitting. If you plan to visit let me know so I can meet you out there. Otherwise, Nick Bonow is the on-site manager and his cell number is 612-916-4404.

Schwalbe, Administrator Cell (952) 221-1089 We have previously mailed this letter of comments on the above referenced project. However, at that time we were unable to get board input due to the deadline. We are re -submitting the Previous letter dated August 14, 2004 under the new date of August 31, 2004 and including the board's comments on page three. The Lower Minnesota River Watershed District (LMRWD) thanks you for the opportunity to review the Moon Valley Gravel Mine in Chanhassen. We are submitting a summary of our engineering review of the grading, drainage, and erosion control plan for the Moon Valley Gravel Mine located in Chanhassen, Minnesota. The plans that were reviewed included the grading, drainage, and erosion control plan dated July, 16, 2004, and a Stormwater Calculations report dated July 21, 2004. Both were prepared by the Sathre-Bergquist firm. Hydrology and water quantity related comments are as follows 1. The curve number selection of 69 for existing conditions seems high given the sandy soils Pl©yc Co,tyN4i7„G prevalent on the site. The curve number should be lowered to 61 to better reflect current site conditions. 2. The curve number selected for proposed land use conditions appears low. (CN=76) For clarity and to better model small storm runoff from the site, the proposed medium density/high density residential areas should be modeled separately from the overall watersheds, rather than lumping them together. This will assist in future reviews in determining if the proposed development is consistent with the current proposal. 3. Times of concentration used in the model from the sheetflow calculations appear to be too long, resulting in underestimated peak discharges. The Manning's "n" value used in the calculations Page 1 of 3 Scott County Government Center 200 4rh Avenue West Shakopee, MN 55379 Phone: (952) 496-8842, Fax: (952) 496-8844 E-mailtertys@lowermn.com SCANNED 0 0 Lower Minnesota River Watershed District corresponds to dense grass conditions, which are likely optimistic given the slopes of the site. A better estimate can be made using either short grass or unpaved conditions to be conservative, especially given the steep slopes on the project site. 4. Overall, the rate controls provided by the proposed ponds meets the 10 year and 100 year prdevelopment discharge rates. However, it does not meet the 2 -year prdevelopment discharge rate. This could be accommodated by installing a small orifice and overflow weir outlet control structure without drastically raising the high water levels from the 10 and 100 year events. P5. Changes resulting from comments #1-3 may change these results. Drainage to Pond 1 from a portion of WS -5P is not accounted for in the rate control calculations not proposed for , runoff from this area 0aaffect pond operation. Modeling of peakprovided for Pond 1. Although this area'flows and rate control for he 2,110, and 100 year eventsll should be re-evaluated with a revised watershed for Pond 1. Watershed WS -1 P does not have clearly defined drainage boundaries. Although it does not enter the portion of the site that is to be regarded, it will nneer�],I be better defind- in order to quantify ��y�'^``````��y��""""`` — whether or not flooding will occur over TH212. A,b1>Q,tUcP �f j . �i�f(,a, 7. The proposed drainage diagram appears to show runoff from the Settlers West Development on top of the bluff draining to a concentrated point at the top of the proposed 2.5 :1 constructed slopes. These concentrated flows must be avoided and prevented in order to prevent severe erosion of the steep slopes. Runoff may need to be piped down the face of the slope at this location. 8. The west end of watershed WS -3P will naturally drain to the channel/wetland to the west, while the -j" ultimate proposed plan indicates it will be directed east to Pond 2. Water quality treatment should r� be provided prior to discharging to the channel/wetland complex. A temporary sediment basin may need tbe instna�ll�dn ,i� this �} ti�onunt,i�ll �fwal development occurs and redirects runoff to Pond 2. �o� tnl� l �I -' d 9. It is not clear how runoff from watershed WS -6P will be directed to the proposed Pond 1. The j grading plans show sheet flow to the south, where it will intersect the proposed site access road. Based solely on contours, it appears runoff will sheetflow over the road and then will continue on to TH 212. eta I r�rdi t�ir wml directed to to Po 1 should be included for review. � I�e�9 h iui� � � h 10, No details regarding the propo ed pond outlets were sub ded for,review. Ata minimum, t ey � t provide skimming up to the 5 -year storm event. The plans do not make it clear how runoff from watershed WS -5P leaves the site. High water levels at any proposed or current outlet may affect the high water levels in Pond 1.rr�i/I(In� . The steep slopes proposed for the site (2.5H:1V) will require substantial efforts be placed on erosion control during construction and vegetation establishment. The site should be thoroughly reviewed for erosion control measures as the current single lines of silt fence shown on the plan are likely not enough given the height and length of the proposed slopes. Water quality related comments are as follows: 13. The stormwater ponds should be designed to achieve a 60% reduction in average annual 60-110S�C phosphorus loads. No details regardin the proposed nutrient removal efficiency of the ponds were provided.

The minimum recommended mean depth is 3 feet for a water quality pond, in order to prevent scour and re -suspension of captured se iment. In addition, at the LMRWD's Board of Manager's meeting held on August 18, 2004, the board made a motion of additional comments as follows: It was moved and seconded to: 1. Send the letter out with recommendations that the Pemton Land Company's plan be altered to meet these requirements laid out in the August 14, 2004 memorandum and Pemtom Land Company should reply to the District for each item in the memorandum. 2. Encourage the City of Chanhassen to work with us in the development of a mutually acceptable agreement to enforce the provisions of the LMRWD 509 Plan and express the expediency of getting the plan in place. If we can't reach a mutual agreement, then the LMRWD will be forced to adopt rules to enforce stormwater management within the City of Chanhassen. 3. We want to hear back from you that through your permitting process you have implemented these standards and if not, why not, and have them send us a copy of the final permit with a plan or conditions adopted.

Stat. § 115B.178 that certain actions proposed to be taken by the city of Chanhassen (the City) at the Moon Valley/Outlot G site, located at the address referenced above (the Site), will not constitute conduct associating the City with the release or threatened release of hazardous substances, pollutants, or contaminants at the Site for the purpose of Minn. Stat § 11513.03, subd. 3(4) (2004). The Minnesota Pollution Control Agency (MPCA) staff in the Voluntary Investigation and Cleanup (VIC) Unit has reviewed the documents submitted for the Site. A gravel mine operated at the Site from the 1940s to approximately 2002. Portions of the Site were also used as a rifle range, a pistol range, and a trap range from the mid-1960s to July 2004. The gravel mining and gun range operations were concentrated in the southern two-thirds of the Site (the Moon Valley parcel). Outlot G, which comprises the northern one-third of the Site, is primarily an undeveloped wooded parcel, except for a small area in the southeast comer that was mined for sand and gravel. The City will be acquiring Outlot G through a charitable donation and plans to preserve that area as greenspace. Although Outlot G is beyond the zone of maximum accumulation for lead shot originating from the trap range, a few pellets were observed on the g ound in Outlot G. The concentration of lead in surface soil samples collected from Outlot G was greater than background conditions in isolated samples but still much less than the Residential Soil Reference Value. For the purpose of this No Association Determination, the Identified Release consists of lead detected in soil on Outlot G. Based upon a review of information provided to the MPCA VIC Program, and subject to the conditions set forth in this letter, a determination is hereby made pursuant to Minn. Stat. § 115B.178, subd. 1 that the Proposed Actions listed below will not associate the City with the Identified Release for the purpose of Minn. Stat. § 11513.03, subd. 3(4) (2004). This determination applies only to the following Proposed Actions: • Acquisition of Outlot G; • Use of Outlot G as a park preserve and open space; and • Construction of recreational trails across Outlot G. 520 Lafayette Rd.

The Proposed Actions shall be carried out as described herein; 2. The City shall cooperate with the MPCA, its employees, contractors, and others acting at the MPCA's direction, in the event that the MPCA takes, or directs others to take, response actions at Outlot G to address the Identified Release or any other as yet unidentified release or threatened release of a hazardous substance, pollutant, or contaminant, including, but not limited to, granting access to Outlot G so that response actions can be taken; and 3. The City shall avoid actions that contribute to the Identified Release or that interfere with response actions required under any MPCA-approved response action plan to address the Identified Release. Pursuant to Minn. Stat. § 115B.178, subd. 1, when the City takes the Proposed Actions in accordance with the determinations in this letter, subject to the conditions stated herein, the Proposed Actions will not associate the City with the Identified Release for the purpose of Minn.

Sin Robert Generous, AICP Senior Planner c: Matt Saam, Assistant City Engineer Dan Herbst, The Pemtom Land Company g:\plan\2004 planning cases\04-27 - moon vaaey gravel minelapproval leVc.doc CITY OF CHANHASSEN CARVER AND HENNEPIN COUNTIES, MINNESOTA FINDINGS OF FACT AND RECOMMENDATION IM01i 0`4 _ z.�] Application of Beatrice Zwiers and Moon Valley Aggregates for an Interim Use Permit to permit grading, excavation and slope restoration. On August 17, 2004, the Chanhassen Planning Commission met at its regularly schedule meeting to consider the application of Beatrice Zwiers and Moon Valley Aggregates, Inc. for an interim use permit for the property located at 100 Flying Cloud Drive. The Planning Commission conducted a public hearing on the proposed interim use was preceded by published and mailed notice. The Planning Commission heard testimony from all interested persons wishing to speak and now makes the following: FINDINGS OF FACT 1. The property is currently zoned A-2, Agricultural Estate District. 2. The property is guided by the Land Use Plan for Residential Medium and High Density. 3. The legal description of the property is: All that part of Government Lot 1, Section 36, Township 116, Range 23, Carver County, Minnesota, which lies northerly of Trunk Highway No. 212; and, 27 acres in the west half of northeast'/4 south of the railroad and north of Trunk Highway No. 212, Section 36, Township 116, Range 23, Carver County, Minnesota; 1 acre in Government Lot 3 north of Trunk Highway 212 being that part of the northwest'/4 of the northeast'/4 and the northeast'/4 of the northwest 'Ain Government lots 2 & 3, Section 36, Township 116, Range 23, Carver County, Minnesota. 4. When approving a conditional use permit, the City must determine the capability of a proposed development with existing and proposed uses. The general issuance standards of the conditional use Section 20-232, include the following 12 items: a. Will not be detrimental to endangerthe public health, safety, comfort, convenience or general welfare of the neighborhood or the city through the stabilization and re - vegetation of the slope and the reduction in site erosion. WANNEp b. Will be consistent with the objectives of the city's comprehensive plan and the zoning code by creating a future development area that may be developed consistently with the land use designation of the property and through the protection and stabilization of the slopes. The earthwork will be maintaining the site in a form suitable for residential use which is compatible with the Comprehensive Plan and this chapter. C. Will be designed, constructed, operated and maintained so to be compatible in appearance with the existing or intended character of the general vicinity and will not change the essential character of that area because the site will be re -vegetated and the slopes stabilized reducing site erosion. The aesthetics of the site will be enhanced with the elimination of the of the gullies/ravines in the site and the establishment of site vegetation. d. Will not be hazardous or disturbing to existing or planned neighboring uses because the grading and drainage will be contained within the site perimeters. Additionally, hours of operation are limited and specific conditions of approval will be in place and enforced by the city. e. Will be served adequately by essential public facilities and services, including streets, police and fire protection, drainage structures, refuse disposal, water and sewer systems and schools; or will be served adequately by such facilities and services provided by the persons or agencies responsible for the establishment of the proposed use since development of the site will be delayed until urban services are available. The use is temporary which does not need to be served by public facilities and services. The proposed grading will prepare the site for future development. The development of the site will require additional city review and approval. f. Will not create excessive requirements for public facilities and services and will not be detrimental to the economic welfare of the community since this is a temporary use. When the site is developed in the future, the development will enhance the city's economic welfare.. g. Will not involve uses, activities, processes, materials, equipment and conditions of operation that will be detrimental to any persons, property or the general welfare due to excessive production of traffic, noise, smoke, fumes, glare, odors, rodents, or trash. The proposed grading could result in a temporary increase in traffic, noise and fumes. The conditions of the approval will provide standards by which the activities should be minimized. h. Will have vehicular approaches to the property which do not create traffic congestion or interfere with traffic or surrounding public thoroughfares. Through the use of signage, limits on the hours of operation, and if traffic becomes congested additional limits on the hours of hauling operation could be instituted, potential traffic problems will be mitigated. i. Will not result in the destruction, loss or damage of solar access, natural, scenic or historic features of major significance. The proposal will result in the removal of some existing canopy. However, the site will be re -vegetated and there will be less bluff impact vis -A -vis the previously approved gradingtrestoration plan for the site. j. Will be aesthetically compatible with the area since the grading and re -vegetation of the site will improve the site aesthetics. k. Will not depreciate surrounding property values since the plan will improve the site and its impacts on the surrounding properties. 1. Will meet standards prescribed for certain uses as provided in, Chapter 7, Article III of the Chanhassen City Code. 5. The planning report #04-27 dated August 17, 2004, prepared by Matt Saam, et al, is incorporated herein.

Commissioner Keefe asked about erosion control and tree planting/removal as well as where on the plan the grading is actually going to take place and how much material is going to be removed. Commissioner Tjornhom asked • Planning Commission SuX — August 17, 2004 • where the creek on the site started and if it would be protected from erosion, if there would be a lot of trucks accessing the site, how long the grading operation would take, if there will be wintertime operations and how the material would be compacted. Commissioner Papke asked about how the site would be graded and whether or not there would be a mountain of fill sitting on the site over the five years. He also questioned the reforestation and if there was a plan to insure the survival of the seedlings. Commissioner Claybaugh asked if there was a monitoring process in place for the seedlings and for clarification on the amount of material to be exported and the phasing plan. Commissioner Keefe asked about environmental issues. Commissioner Sacchet asked about environmental status of some original tree growth, the amount of trees being cut, the creation of new bluffs, how the security amount was calculated, verification of the number of trees recommended for replacement, if the proposal is consistent with the City's Comprehensive Plan and if staff has seen any studies from the applicant regarding trees, topography, bluffs, utility services, wetlands and storm water. Matt Saam and Kate Aanenson responded to the Commissioners' questions. The applicant, Dan Herbst of The Pemtom Company, addressed the Planning Commission and answered questions from the Commission.

Sacchet: Matt, do you want to give us your staff report, please? Planning Commission Meg — August 17, 2004 0 Saam: Sure. Thank you Mr. Chairman and Planning Commissioners. First of all, let's get acquainted with where this site is located. If you will look on your monitor, the site is in the south end of Chanhassen immediately north of 212 along the eastern city limits of Chanhassen and just south of the recently approved Settlers West development. A little bit of history on this site: In past years, some 20 to 30 years ago, the site was used for, among other things, a rifle range and a ski hill. Most recently it has been used for a mining pit. In 1996, the City approved a grading plan and restoration plan for the site with the property owners the Zwiers. The plan is shown on your monitor. Basically, what the plan did is it concentrated on the east half of the site east of an existing wetland that goes through the site. The plan allowed the applicant to grade down at 2.5 to 1 slope to have somewhat of a developable area in the middle of the site approximately 8.5 acres. What I would like to highlight is the plan allowed the applicant to go in the bluff areas along the southwest comer here and the northwest corner. A little over 3 acres, I think the narrative says. It also impacted some trees. In looking at this, the applicant would now like to modify this plan to restore the site using some of the same guidelines, the 2.5 to 1 slopes and whatnot. So we now arrive with the current plan. The current plan, while it does utilize the eastern half of the site, also goes clear over to an existing creek or wetland and then also even farther west than that to the far western corner of the property that the Zwiers own. Again, staying with the previously approved plan in 1996 what that's done is proposing is to grade down at 2.5 to 1 slopes to this time vegetate the hill putting a wood -fiber blanket on it in addition to trees that staff is recommending. Some of the differences that I would like to highlight between this plan and the old plan, that the amount of bluff impact on this plan. The old plan went into this upper corner right here. This plan isn't doing that. They're limiting the amount of bluff impact that they have; however, with that they are proposing to go farther to the west here into more trees, approximately 7.3 acres. By doing that it provides the applicant with more developable area which, of course, is the ultimate goal here and the amount is plus or minus 14 acres on this eastern half. It wouldn't be developed until sewer and water got to the site in approximately 10+ years, around 2015. It's currently in the comprehensive plan to receive sewer and water. The development would come back at a later time. At this time they are only looking to grade the site and restore the site. One of the things that staff is recommending ... if you could zoom in here Justin, just a bit. This western edge just along the creek, the applicant has a high point in here at which he quits filling and then starts dropping down again toward the creek. Staff is recommending that at about that high point we stop the grading operation. That would preserve more of the trees in this area. It would also preserve a little over half a bluff area so we would get additional trees that are preserved. We would also preserve the natural drainage of this area since it slopes down toward the creek. We want to preserve that to protect this wetland and creek area. We believe, as I said, it more closely follows the existing drainage and would eliminate the need for additional storm sewer in this area when it would be developed in the future because since its dropping off you would have to capture that water in storm sewer and route it all the way back over to this pond right here. The applicant is proposing in terms of drainage two ponds on the site which would be sized for full development of the site. We are assuming that basically the whole flat area would be multi -family housing which the land use guides it. So we would be set up in terms of ponding and drainage for future development. Erosion control is a big issue on this site. That's one of the City's goals with the site is to restore it and the applicant has done a fairly good of showing major silt fence of course on the site and then a lot of wood -fiber blanket on the steep slopes. We may have to upgrade the type of blanket 2 Planning Commission Meg — August 17, 2004 because of the very steep slopes and the amount of water that would be coming off there. Overall, the grading plan looks good from an erosion control standpoint. I would like to point out there are two, the site is right here. Erie Avenue, a private street, is kind of in the middle of the site. There are two existing lots which are highlighted on your monitor that are privately owned. The Zwiers don't own them. So to complete the grading plan that they are proposing those lots would either have to be bought or some way come into play with this grading plan. We did put in a condition that access to the lots will have to be maintained throughout this process, at least until the Zwiers or somebody else would purchase them to bring them into the development. With that, we are recommending approval with the conditions outlined in the staff report and I would be happy to take any questions. Sacchet: Thank you, Matt. Questions for staff? Do you want to start Dan? Keefe: I have a couple of questions. Can we just go back to the erosion control just for a little bit and just comment a little bit more on what you think really needs to be done because just in looking at it, its really steep. From what we saw there's a lot of rutting going on and you feel that wood -fiber with, and there were a lot of trees called out for on the plan. Will it be enough to kind of stabilize that? Saam: The term wood -fiber blanket is really a general type term. There are specific categories based on steepness and the amount of velocity that the water can speed up to coming down the hill so it will have to be a certain type of blanket. It will have to be stapled in so it holds on the slope. The blanket will have to come in contact with the slope at all times. Also, the areas at the bottom of the slope right around here where my finger is going, specifically in this corner here, this is kind of a swale or ditch if you can imagine coming down the slope where the water would be concentrated. That will be a big area where erosion could occur so we will have to stabilize that. I think the staff report goes into some detail on that. They also have to put in sediment basins to control the drainage on the site but I think we can work through it. Is it your typical one? No, definitely not but I think there are items that we can use in terms of blankets and different types of silt fences and bales that we can use on this site. Keefe: Is the highlighted area, the green area that you got there, is that where most of the trees would be or are we looking throughout the site? Because I think he called for, I don't remember, is it 20,000 trees? Is it mostly on the hillside or is it in the flat area? Sawn: That's my understanding. It's the smaller, bare root I think they call them? I'm not a forester. They are smaller type trees. I think the applicant's done some of that work before me. They can go into some detail. It is my understanding they would all have to be hand placed in there. With that slope I think the most you could get up there is bobcats and that sort of thing so we are not talking about any big spade coming in there or anything like that. Keefe: Can you comment a little bit more about the trees that would be removed? I can't speak to the quality but it seems like the whole area hasn't been really maintained all that well for a number of years. The quality of the trees in the areas that they would be removed, it guess it would be the center area, any comments in regards to that whether they are poor quality with all Planning Commission Meegg — August 17, 2004 • the rutting which has gone on out there. Are we looking at trees that are falling down a lot? Any comments you can make on that? Seam: Just a couple. Again, I'm not a forester; I'm not a tree expert. Just from visiting the site there are certain areas with what I would call nice trees and there are some other areas where I would say they are more of the scrub -type variety. Kate, would you have anything to add? Aanenson: Again, I think if that was a trade-off as we go out and visit the site to look at if there are areas ... I think that is one of the points the applicant brought out. When you look at the one knoll, maybe its not as good there but certainly on the top one back towards the creek, the trees, while they may not be as high quality, they are preserving the existing slope and providing some habitat. I think that staff's position is for maybe looking at the one finger or knoll that sticks out, maybe that might not be as high quality. Could that maybe be removed? Maybe originally the applicant chose not to remove it but we would treat that as a minimum ... that creek, preserve that instead. Saam: Just adding off that. That's a good point. With staff's recommendation to save what I'll call the western half going down to the creek, if we could save the existing vegetation there it would greatly minimize erosion and that type of thing, no matter the variety of the trees. Keefe: I have one last question. In regards to the 1.8 million cubic feet of material that would be removed, could you give us a sense of where that on this plan, is it throughout the entire plan or are we talking just in the flat area and does that consist of what? Are we just pushing the dirt around in there that we are going to remove that is sort of the topsoil? Are we talking digging down? Saam: There is a number of questions in there but it is my understanding that the 1.8 million number is the excess number that they would have. In other words, the number that would have to be hauled out. As far as where they are cutting, this are is being cut down. Initially, up here they are restoring the existing cliffs out there where the erosion has been happening, but then as you go down into here they are cutting at 2.5 to 1 and that's to get this plateau area for future development of the site. Sacchet: Thanks, Dan. Bethany, any questions? Tjornhom: I have a couple of questions. Looking at the map, where does the creek start? Does it just start where that little circle is? Does it just start there like all the sudden there is a creek or is it fed by something else? Saam: This up here I think you're referring to? This is the Hennepin County Regional Corridor or LRT Trail. There is drainage from Settlers West which eventually comes down there. It's a ditch -type system, I'll call it. Everything in this area eventually goes to the Minnesota River valley so its all tributary to that and that's what I would call this, the beginning of that wetland. Tjornhom: With the grading and you've mentioned when it gets to that slope by the creek, you're going to stop the grading, correct? 4 Planning Commission MelIg — August 17, 2004 • Saam: Yes. Tjomhom: So then you won't have erosion going into the creek? Is that happening now? Is there erosion going into the creek now? Saam: No, that's not my understanding. Where the erosion is happening now is inside the site. Basically, it's been carved out. It's kind of like a bowl now with very steep slopes, 1 to 1 or more in areas. Tjomhom: So right now the creek is protected and its not really... Saam: Yes, as far as I can tell the existing creek is protected. Tjornhom: That way then, even after the grading is done and... Saam: Correct. That's what we are recommending. Tjomhom: OK. I have a question with the trucking also. That's a lot of trucks coming in and out with fill and without fill. How long do you think it will take? Saam: That was a big concern of ours when we talked to the applicant, too. As the staff report says, the applicant is proposing a five year kind of phasing plan for the project and because of the amount of excess that will have to be trucked out, frankly it will take probably that long to find homes for 1.8 million cubic yards. A rough number that we use in engineering is 10 cubic yards per truck. Maybe you'll get some more if it's bigger than that but usually you get 10 to 12 so that's quite a few trucks going out of there. Maybe that thing can go into this but they are planning to do it in phases so maybe it's a fifth of that number, 30,000 to 40,000 one year that's trucked out and so on over five years. Tjornhom: This is a crazy question but, is this a seasonal operation or will this be happening in the wintertime also? Saam: That's a good question. I would guess it's without snow but maybe that's something we should ask the applicant. I haven't asked that. Tjornhom: OK. And this is just for my information also, where all the gravel is obviously what is up against, what they will be filling up against, is there a problem putting dirt along that gravel wall? Will that settle any way or how does that work? Saam: There's always that potential but they will have to compact it and use certain construction techniques to make sure that it all doesn't slough off in a rainstorm maybe. Tjornhom: That's what I was thinking. Planning Commission MedOg — August 17, 2004 • Saam: And that's why it's key to have the erosion control in place before really the big operation starts. That's why you want to have your perimeter silt fence up and sediment -type basin so if say it would slough off it wouldn't leave their site and it would just be their problem to put back into place because what we don't want is for it to affect Minnesota river valley or neighbors. Tjomhom: Will they kind of wrap or put something on that gravel before they would start to put fill up against it or no? Saam: Wrap I don't think would be the right word. Running dozers perpendicular to the slope, certain construction techniques to make sure that it gets compacted. Tjomhom: So no material or anything to hold in place? Saam: Material? Dirt. Yes. Tjomhom: I guess that's why I'm trying to figure out. When you put the dirt and sand together they compliment each other where all of the sudden, sand is obviously more porous than dirt is and so when sand is taking in more water will that start to erode the dirt from the hill? Saam: I guess I'm not following you. What they'll do is remove the topsoil wherever there is some and fill in with the existing dirt on the site. If they find other sand that will go back in but it's predominately clay is out there among other things. I know there's been some filling of a lime particulate out there. Maybe the applicant's environmental engineer can go into that a little more too. Tjomhom: OK. That's all. Sacchet: Thanks, Bethany. Kurt? Papke: Just two questions. To follow on the fill issue; if it's going to take five years to get rid of all the fill, does the applicant complete their grading job and then make a big mountain in the middle of the plateau that has to be managed over five years and where does the fill come from during that five years or does the grading happen over five years? Saam: The five years is the applicant's proposal or schedule to complete this entire operation but what we are proposing is on an annual basis they obtain a grading permit from us and this is an interim use permit, but maybe we'll need an interim grading plan to show are they going to work in this corner now and, if they are, how is that going to be stabilized? Maybe we will need erosion control there that will come down in the future. Is that getting at what your question was? Papke: So the grading will be sequenced and so as the grading is done the fill will be removed so we won't end up with a mountain of gravel for five years? That's kind of what I was getting to. 0 Planning Commission Meegg — August 17, 2004 • Saam: Correct. As I said earlier, maybe they'll take out 30,000 to 40,000 a year over phases. Papke: But it won't accumulate in one spot either during that period of time? Saam: Again, they have an excess so they can spread it out if they finish in the fall, reseed it, and then maybe they won't come back until the next spring. We need additional information right now from the applicant to get an idea of what the sequencing or phasing is. Papke: The only other question I had is on the reforestation, raising 10,000 seedlings out there with deer eating their dinner every night off the seedlings and so on can be a real challenge. Is there any kind of plan in place for how we maximize the survival rate of whatever goes in there? Is there a part of the plan that addresses that? Aanenson: I believe the Forester did talk to the applicant this afternoon about the tubex trees. It is the assumption that we're putting in more smaller sapling types and that they would also be in tubes and that would protect them from the deer and the rabbits and that they would be protected as we move along with a security, to make sure that they survive. Papke: Is there any kind of black dirt going in? Right now you would be planting trees and gravel in essence. Saam: No. What we require, as we do with every new development, the four to five inches of black dirt at the surface and then they vegetate on that. If they don't have it on site they'll have to haul in some black dirt eventually. Papke: OK. That's all. Sacchet: Thanks, Kurt. Craig, any questions for staff? Claybaugh: Most questions have been asked. Did the City Forester have any specific comments? I assume she's been out to the site? Aanenson: Her comments are in the staff report and again, the goal that we looked at and going back to the original plan that was approved through litigation was just, we said re-establish the slope. The City's goal is to get trees back on the slope and that's what the applicant wants to do too. Then the property does become part of the MUSA and it is available or ripe for development. Then they've got the vegetation in place. So we've recommended a variety of different saplings. We've put a lot in there, 20,000. I think they were a little shocked at that. We're looking at six to eight inches tall and that gives us a higher survival rate, the spacing requirements and issues ... Not all of them will survive but ... comprise between that but we think that's very doable. Claybaugh: Kurt asked the first half of the question of just getting those seedlings the best start possible. Is there a monitoring process in place? Planning Commission Meelog — August 17, 2004 • Aanenson: I think that was the first issue that we had. We did go with the applicant and looked at some of their other sites that they've done that are on very steep slopes because we wanted to increase our confidence that this was the right way to go so we did look at some other projects and believe that it can be successful. Claybaugh: This may be a question better suited for the applicant but I'll go ahead and throw it by and you can check right over what you have there. Actually, at 30,000 to 40,000 cubic yards per year they will be out there a lot longer than five years to export over a million yards. You've got the first phase coming up. I don't know if you know how many cubic yards are involved with that or what kind of a timeline is associated with that? Saam: I'm sorry. My math was off. It would have been about 300,000 to 400,000. The timeline again is five years. Claybaugh: This first phase. I'm trying to break it down a little bit so we can get a little better perspective so it... Saam: Sure. Let me try to highlight that as much as I know and the applicant can add anything he wants. As far as we know, they want to get started along this northeast corner. Claybaugh: Down at the toe for Settlers Ridge, correct? Salm: Yes, at the southern end of Settlers West to get that established and then I believe its basically moving from east to west after that. Claybaugh: Again, I'll come back to the question that Kurt asked. Are they planning on staging any of this material, of this excess on site or are they looking at exporting it as them move it to avoid handling the material twice? Saam: That I don't have a handle on. Maybe that's something that the applicant can add. Claybaugh: They already covered the topsoil element... that's really all the questions I have. Thanks, Matt. Keefe: Known environmental issues that are out there. I see that a phase I is called for. Do we know of anything significant? Saam: In the environmental assessment the phase I is related to, we know a rifle range of shooting range was at one time going on at the site so we are thinking there may be some lead - type contaminants so we just want to have an assessment done to see what that will shake out. Sacchet: Actually, I have a couple questions, too. One thing, and I don't know whether this can be answered, somewhere I picked up on a, I think it was a DNR map, that in that area we have some of the original growth left in terms of the trees which is actually very special from an environmental viewpoint. I don't think it's mentioned in the staff report but I wondered do we have any knowledge about this at this point? It was one of my concerns I brought up when we Planning Commission McAg — August 17, 2004 • looked at Settlers West and I think I would like to also consider that point in the context here, if indeed there is such a point. Is that not something that has come up to your attention so far? Saam: No, not to my attention and we did send it out to review agencies so maybe we haven't heard back from the DNR yet. Sacchet: OK. In terms of the math of what we are actually doing, and obviously I'm mostly interested in the math of how much trees we're cutting, personally. We're cutting 7.3 acres just on the east side of the creek, that's correct? Saam: Yes. The 7.3 is... Sacchet: ...what they're proposing. Saam: Yes. Currently and that's only on the east side. That's a good point. Along the west side of the creek there's another... Sacchet: ...there's another 4 acres, right? Saam: Yes. 4.2. Sacchet: Now, one thing I'm confused and you explained a little bit how you were proposing to reduce a little bit the tree impact by the slope on down on the other side to what's the creek. Staff report has two different figures. On page 3 it says 1.6 acres and page 5 it says 1.4 acres will be saved. Which one is the accurate figure, do we know? Because I was just curious do we have a clear idea of how much we are saving? It's not a huge difference. Saam: This is a blow-up, a 50 -scale plan of just the eastern half of the site and what I did here was draw in red basically the line of where we are proposing the grading would stop. Sacchet: And that would be the existing 756 contour? Saam: Yes. Their last proposed contour would be this, and you can't see it, but it's the 756. Sc west of this line on this area, that would be preserved. I actually used an instrument, we have to calc up that area, and I came up with 1.6 acres. Jill has 1.4 so it's right around that 1.5 acres of preserve area. Sacchet: OK. Good. Has that been discussed with the applicant or is this a new... Aanenson: He's aware of... Sacchet: You make a point that then there would be trees cut for the construction at that point, if any, where the buildings go, like a custom -grading type of approach. Is that the idea? Saam: I haven't seen any development plan per se with building pads and that sort of thing unless the applicant has something to share tonight I haven't seen it to that much detail. 0 Planning Commission Mee* — August 17, 2004 • Sacchet: We're not to that level... OK, that's fine. Now, one question I have with creating those 2.5 to 1 slopes, we're actually creating new bluffs, is that accurate? Does that meet, how steep is a bluff? Saam: Yes, that's a good point and it's something, I didn't think of it in that fashion but yes, that slope is 40%, I believe, and our bluff ordinance says 30% with a 25 -foot elevation difference. Sacchet: I was just wondering if my memory was accurate. 30 -something percent. So really all these slopes are going to be considered bluffs? Aanenson: Yes. Saam: Yes, but again, we are restoring a bad situation, by that erosion we'd be vegetating that area. Sacchet: So once they are revegetated would they fall under our bluff ordinance? Saam: Look at Kate for an interpretation. Aanenson: I'm not sure if it's pertinent to the discussion in the opinion of ... (the tape was changed at this point)... density credits nor are they taking any density credit for that area. Sacchet: Well the concern is that bluff has special setback requirements, doesn't it? Aanenson: Yes. Sacchet: We'll cross this bridge when we get to it. Aanenson: I'm not sure it's going to impact it in that format. It doesn't have development density right on that part. The only part we did talk about is if we want to guide the berm because the ordinance doesn't address tree removal except for the fact that you replace it. But it does address the slope issue. Keefe: Would the bluff, now assuming you make bluffs, right? When they come in and presuming somebody wants to develop it then they would have to deal with the bluff setback. Is that kind of what you're? Sacchet: Well I wonder what, I mean that is something to be certainly considering because that may be an impact that... Aanenson: It's a 30 -foot setback. More than likely that type of product is going to have something... Sacchet: It's going to have room around anyhow. Alright. We'll deal with it when we get there. For ignoramuses like myself, what's a dozer? 10 Planning Commission MeeQ —August 17, 2004 • Saam: I'm sorry, a bulldozer. Sacchet: As in bulldozer? Saam: Yes. Sacchet: It says here the slope should be tracked with a dozer at all times. Saam: Yes. Sacchet: So, a visible dozer. Just to beclear. A lot of the conditions, let's quickly go through these things, too. One, condition 6 talks about an escrow letter of credit to be required for $619,000. How is that figure calculated? Saam: It was just grabbed out of the air. I'm kidding. We got a cost estimate from the applicant's engineer as we always do. In terms of the overall grading of the site what it would take then we review that, tack on 10% and that's how we arrive at that figure. Sacchet: OK. So that's a calculated figure. Aanenson: Let me qualify that, too. I think one of the things that we are looking at if we do a phasing plan that we probably have a rolling letter of credit which we do on a lot of other big projects is when there is open landscaping, if there is so much open land we just move that to the different phases and that would be something that we'd probably look at with this project, too. If we're doing it in a five-year, where we would have just the amount in escrow needed for that portion to re-establish, if that makes some sense. Sacchet: OK. The trees we're requiring, the staff report talks about between 9,531 and 38,080 trees which is a pretty big range and in the condition you say approximately 20,000. There seems to be a big range. Are you not comfortable being more specific or what does it depend on? Aanenson: The note that I have from the Forester was that 20,000 is what she's recommending for replacement. Sacchet: OK. So the 20,000 is the figure we're going to go with? Aanenson: Correct. Sacchet: OK. Those two properties, 230 and 240 Erie Avenue, at this point they are being left alone? Aanenson: Correct. 11 Planning Commission Meeh — August 17, 2004 • Sacchet: OK. In terms of the Comprehensive Plan, and I think that's going to start wrapping up my questions, we obviously have a juggle here between a relatively bad situation with an abandoned rifle range and a mine with a lot of erosion, and on the other hand, we have a relatively sensitive natural environment around it. I assume with staff bringing this forward you believe this is consistent with the Comprehensive Plan in terms of the objectives of being compatible with the revegetation and ultimately with not destroying any natural scenic or historic features of any significance? Could you speak of that just a little bit? Aanenson: Yes. Let me just kind of refrain this. When the applicant came in to do Settlers West, what we decided on that is we wanted to, as a part of that, was to get rid of some of the problems that were on the bottom, this piece that we're talking about tonight. Specifically, the shooting range, the cell tower, those were the things that were a nuisance and actually the gravel mining operation itself, and re-establish the slope that eroding terribly and actually get better vegetation on the slopes. That was the overriding goal. Ultimately, while doing the grading we're still a number of years, at least 10 years out, before municipal services are there so if we can get the slopes re-established and the vegetation growing, we think that makes sense to get the site cleaned up and re-establish that slope for Settlers West and the other Settlers side. We think that is a good thing. Saam: I'll just add one more thing. Again, let me reiterate, this applicant has the right to do that initial grading plan which went into the bluff, didn't take out as many trees but took out more of the bluff. We didn't really have a reforestation plan it is my understanding with the original 1996 plan. Jump ahead to now, we are getting a revegetation plan, not as much bluff destruction, with staff's recommendation not as much tree removal. Still quite a bit but not as much. Sacchet: So you believe it's a healthy balance? Aanenson: Correct. Saam: We do. Sacchet: My last question, I believe this was the letter actually from the applicant, it makes a point that extensive studies are underway regarding trees, topography, bluffs, utility services, wetlands and storm water. It might be more of a question for the applicant but have you seen any of those? Saam: I guess I'm not sure if he's referring to the feasibility type study. Certainly the City isn't for this area right now. Sacchet: We'll let the applicant speak to that one. That's all the questions. Thank you very much. With that, I would like to ask the applicant if you want to come forward, if you want to add some more and share your vision with us here. Please, if you can state your name and address for the record. Herbst: Good evening. Dan Herbst of The Pemtom Company at 7640 Crimson Bay in Chanhassen. Good evening Mr. Chair, members of the Planning Board and professional staff. 12 Planning Commission Meet — August 17, 2004 • also want to introduce Justin Larson. You met him during our Settlers West. Justin's with Sathre-Bergquist. His sidekick has got his kid playing hockey tonight, Bob Payette, so he's missing. I'm also fortunate to have Jim Aiken with us, an environmental engineer with McCain & Associates, does all kinds of environmental issues throughout the state, public and private, and also Dan Cook from The Pemtom Company. The reason I'm here is that I was able to acquire the upper plateau from Mrs. Zwiers and came before and got Settlers West approved and it was very important to me, not only what happened up above, but what was going to happen down below because I had a vested interest in it. I negotiated with her a five-year option because I, like you, want to see that restored and I want to see it revegetated and, as I got into it, she asked me if I would take it a step further and said what is the City's Comprehensive Plan here and what can I expect to do with this piece in the future. I think to just fulfill the requirements of restoration and do the 1992 plan that was in your 1996 settlement I think wouldn't do justice to the site or to your Comprehensive Plan. As I indicated to you out in the field, you took a very bold approach with guiding 70 plus acres of that site for high-density housing. I think there is some real potential to do something very creative there. Although you didn't see any progress out there tonight, I feel there has been great progress. We were able to start our development up on top and as you know the erosion that has been coming off that bluff where Settlers West is, hopefully a month from now when we do that berm up on top and put in the storm sewer system, all of the erosion that's been coming off of that northeast corner will be eliminated. We got that transmission tower removed to the great pleasure of people in Chanhassen and people at Settlers Ridge on the east. We got the range shut down. We got the dumping and filling stopped and now I think, although you didn't see any of that, to me that's been great progress because I've been listening to the range and watching things erode out there and gotten many letters in your file also from the City of Eden Prairie. They paid dearly for the Richard J. Anderson Conservation Area and that's been eroding through the years and the owner, who is now deceased, was not being very cooperative with the City. I think we've got all that in place now. We've got a developer's agreement with you. We've got a developer's agreement with Eden Prairie. Now we want to move forward and I think this is the first step. I take the blame for comparing what I submitted to you to the 1996 plan and comparing the development potential of that plan to what we are proposing because I don't think, again, that does justification to the site. Tonight I think it's important that we deal with what I've submitted and talk through our phasing plan and talk to the issues you have, but then come back to you with additional studies about trees; however, there is old growth there, what kind of trees are there and then come back to you with what may potentially happen on that site. I don't know, it will probably be a few years down the road when you are going to be looking at redoing your Comprehensive Plan but we want to be very much a part of that. As ugly as that place looks, I'm really excited about it. We were all looking to the north and to the west but if you turned around and saw the beautiful views and you saw the potential there to create some plateaus for housing, it could be a very, very unique site, something that you don't have in the City. I think if we work for that vision, work for that dream, I think we could really, really have something there. I don't want to go through all the arithmetic because you have it in front of you but yes, the original plan had less bluff than we are proposing now being, had more bluff being damaged but more trees. I love trees. I spent millions and millions of dollars in my life replanting trees and, to be honest with you, I've had greater success planting and growing than I have trying to maintain trees. All of the goals I have for that site are the same as yours. I would like to maybe, should be just go through some of your questions with the trees? Let's start with the trees because I know they are all important to 13 Planning Commission Mee* — August 17, 2004 • all of us but you know I've been working with Jill and Kate, very sensitive people to the tree issues, and you get mixed readings every time you go to get opinions. We called one DNR individual and he said, as indicated in your site tonight, we have too many trees up there. Let's look at planting some unique prairie grasses. I said I don't think they're going to buy into that deal. Then I talked with the other lady at the DNR today and she said she would really like to see about 500 of bare -root or root stock planted per acre which would be about 10,000 trees. She has them available on a first-come, first-served basis. There are no guarantees but she has some 6:42" material which we could buy from her. She's recommending that we do a mixture of an oak and my favorite little tree is that eastern red cedar. It's a very tough tree and we're talking about putting on a southern face slope. Although I think we kept talking about granular material out there, there really isn't much good granular material left out there. It's all been picked over for the last 75 years and what's there is very, very marginal. In fact, some of the banks you were looking at weren't granular at all. It was basically clay material. That is going to be a good basis for us to do a restoration and do the build up of those 2.5 to 1 slopes and the 40% slope there and then I think you've got some very stiff requirements for us from that and from the Carver people of how we're going to re -seed that and protect. I took staff out to Settlers Ridge and showed them similar banks along the Flying Cloud Airport. We did some 2.5 slopes out there. We put fiber blanket in and we put bare root in there and it's doing quite well. I'm very proud of it. We took the extra step. We didn't just plant it in the ground. We put the base material on it. We put the tubes on it. We put the stakes. You also need a lot of luck when you've got that kind of drainage sloping. You need moisture at the right time of the year but I think we can do a good job. Also, we had some very severe sloping at Settlers Ridge, the project to the east. A very severe ravine, much more severe than we're dealing with here and I've taken most of your staff out there. Those have no trees on them but the vegetation from the fiber blanket and the natural material that's coming back in from whatever it is, weeds, or whatever is doing a wonderful job and is very, very, very attractive so it's done quite well. Anyway, when I read the staff report I had the same issue. What's gong on here? 9,500 to 40,000 roughly in trees. I think, in my mind the DNR submittal would be very good, 10,000 trees, but if Jill's insisting on going for the 20,000 and we can make a good buy on those next spring and we could do it in phases, again I want to do a great job thereon those trees. The trees will be important once we get it all established but we've got to get those hills established first, we've got to get the fiber blanket set, we've got to get the grass to grow before we start marching up there with people and disturbing that and start to plant trees because we can't a machine or a bobcat up there. On the grading issue, we have no intentions that I'm aware of mining that site and stockpiling in the middle. As you know, that dirt business, to move it twice is a costly deal. I think we've like to do it in the five phases we talked about and for my own self -interests I want to get Settlers Ridge and Settlers West taken care of, this phase of this neighborhood. This is pretty much established already although it exceeds, it's a little steeper than 40% but we build there second and protect the parkland there and then move our way through five years hopefully if we can find a home for that material and do this in stages. I think it's easy to look at this site and say gee, I don't want to lose all those trees and I want to do that. I may want to limit the development area and hopefully when you come in with a plan you'll open it up and take another look at it. I think there is some danger to shrinking what we have here. Ordinances get stricter and all of us get tougher on our requirements of how we develop things but I do think I was anemic here in what I submitted to you. I think I really should have submitted to you a visionary type plan where we could fulfill your Comprehensive Plan and put a, this proposal only has 18 usable acres and we'd 14 Planning Commission MeeQ —August 17, 2004 • have a hard -press knowing what I know in the marketplace today to probably even get 200 housing units up there. That really isn't a real creative plan in my mind. We can't get a good mixed use. It's going to be also tough with 200-300 housing units to bring that pipe from 101 all the way down to this site and justify that so I think we want you to work with us and come up with a visionary type plan. I would like to expand in the future with you, in discussions with you, the development area. If we are able to get a good plateau up there, maybe 25 acres of land to use instead of the 18 we could come up with a good mixed use. Some of the land that's not shown on the plans to the west is guided Office/Industrial. I think you can vision neighborhood commercial and office. Some of the things you saw in a grand scale at Edinborough, on a smaller scale here. That type of product is going to be great for the City. It's going to fulfill some of your housing needs that we're going to have to convince you of that. It's going to give you additional park fees. It's going to give you additional revenue stream. Most of these townhouse projects, I talked with Gordon Hughes today, the City Manager of Edina, again he'd like to bring her back there and tell you what they did but, very little of what's out there is maintained by the City of Eden Prairie except those bridges going over the streets. All of the interior streets serving all of those condominiums and townhouses, the senior high rise, the offices, the retail and the theatre, are all privately maintained so the revenue stream coming into the city is phenomenal because you don't have the revenue going out. I think we can show you the numbers on that eventually if we can get the densities and the land mass to create a great plan for you. Any other questions? Sacchet: Questions for the applicant? Keefe: Are you OK in establishing the ponding now or later on? Herbst: No, I think the ponding has to come in real early. We didn't take you around, we didn't have time for that but there is some slurry areas out there now that have been holding runoff but I think we want to fix those up. Keefe: OK. If I'm looking at pond one, access to the two existing homes, it isn't clear to me exactly how, I think they stay and you ... their access would be through the first pond. That's how it appears on the plan and I'm curious to... Herbst: That's probably at least five years out. The grading, as I see would occur here, this pond will take care of all their farms through here. This would be obviously before we could go into here. We've got to work out a hardship situation with the two homeowners and then we've got to come in with a specific use plan for that because, this is showing the ultimate use with a driveway going up to the site and more ponding coming here before it gets to the creek. That pond is just there to pick up the drainage so it wouldn't get to the creek. Keefe: It is a part of what we are approving? Herbst: Correct. Keefe: It needs to be worked out in terms of where the exact location of the pond would be? 15 Planning Commission Meet — August 17, 2004 • Herbst: It cannot be accomplished until we, there's easements, that the two homeowners that live there have a legal interest in so we have to treat those homeowners fairly. We have to work out that easement deal. Sacchet: Has there been any discussion with those homeowners? Herbst: Dan Cook has talked to I think both of them and I'm not in the position since I'm on the option end of things to be purchasing the property but I think as we move there Mrs. Zwiers and myself have got to work something out with those homeowners. Sacchet: So that's still to come basically? Herbst: Yes. Sacchet: Sorry, I didn't mean to interrupt. Any other questions? Claybaugh: With respect to your phase I, could you give us a little bit of a overview in terms of timeline in what you see going out for export, just to put that in perspective? Herbst: I would, I'm just guessing, and maybe I'll let Justin answer that but I want that done this fall because I've got housing up on top and it's not a real large site. It's pretty steep but I would like to come in and get the permit for that and bond for that and have that accomplished this year because of what's going on up above. Quantities and material, do you know what's in that first phase? Justin Larson: In the first phase we haven't really ... but I think it would be probably minimal, to tell you the truth just because of the way the slope is... Herbst: Probably under 100,000 yards I'm guessing. Sacchet: So what you're saying is the first phase you pretty much balance the material? Larson: That's right. I don't think until we start going west that I don't think the earthwork will be extensive as far as having to export. Claybaugh: In terms of your months of operation from year to year over the five years, what do you anticipate? Herbst: Well, I think it depends on how granular it is. To me, it doesn't look real granular. Unless it's granular, it's hard to work with during the frost season but that phase I that you're asking about is very important for me to get done this year if at all possible. Claybaugh: I'm just trying to get into the quantities that you would be exporting and the effect that may or may not have on... 16 Planning Commission McAR — August 17, 2004 • Herbst: I would doubt if there's any export there in that first or second phase. There's enough up and down material out there that we got to get balance out and get this pond taken care of before we're going to start looking at going down the road. Claybaugh: Have you exported this kind of quantity on any other projects that you've done? Herbst: I have not. We're grading over a couple billion yards out at the airport right now but it's balancing. Last year I think I told you I had a 100,000 on that first site at Hennepin Village and even though it was granular, it's difficult. Sometimes having excess material is a blessing but mostly I found it to be a curse. Claybaugh: That actually just generates a little bit more concern that there's only 100,000 going out in phase I. That puts the bulk of the material on the other phases. Have you considered what kind of impact any whole schedule would have on how you would tackle that? Herbst: I'm going to leave that to probably the grading contractors. I think we can work with Matt on that. He's probably more experienced with large quantities like this before. Claybaugh: Nicely deferred. Herbst: I have not experienced that so I want to be honest with you. Papke: I'm not sure if this is a staff or an applicant question but one of the things we haven't touched on yet is how much of this is visible from the LRT trail? There's some of the most spectacular vistas in Chanhassen are on that trail and I'm sure, I know there's like a park bench up on the trail there where you can look down into Shakopee and I'm having difficulty visualizing where some of those site points are in relationship to this because I would hate to see us end up with what is now a beautiful, the most beautiful view in Chanhassen looking down on something that isn't attractive. Herbst: If your talking about up above, I guess you've got to pick a point, but the trail itself you can see it right here, more than 100 feet down below this right now. The trail is very recessed... Papke: But there are a couple of spots where it peeks out there and I'm not sure exactly where. Herbst: When you start up at the trail when I've jogged it or walked it, you can look down, you're kind of looking more very southwesterly down that chute to Shakopee and I don't think anything here is going to be impacting that. Papke: That was my major question. So none of this is visible from the trail? Aanenson: Ultimately, when it's developed you may see something but the goal was to revegetate it so you kind of catch up with that but as far as knocking down the bluff, that was one of the reasons why we pulled back the one slope on the other side of the creek. When your even on Erie, you can't see your crossing, you still wouldn't be able to see. And that's the topographic break that we're trying to maintain. 17 Planning Commission MeeQ — August 17, 2004 • Papke: OK. Herbst: As you know it's pretty severely cut. Every time I go down there I say how in the world could they do this with horses? It was a major, major cut so it's very recessed. Sacchet: I asked you this question when we looked at the site earlier tonight and I would like you to address this for the whole meeting for the record also. Why do we have 1.8 million cubic yards of material that have to leave the site? Why can't it be balanced more on site? Herbst: I think that was the first question I had. The engineer said it's just truly impossible. If you were to put this material back in, all you would have was, the bluff probably came way, way out at one point in time and dropped way down. If you were to try and balance the material and leave that 1.8 on the site there would be at some point in time you're just going to push that bluff further and further out towards 212 and you're not going to have any land left to use. As you know, your standards, we're even showing I think a 4% rise stepping up this thing and we're still taking out that many. If we were to make it a little more level there would be a lot more material coming out of there. It's very close to what was approved in your original plan to restore that site. Sacchet: Do you remember how much would have to come out with the original plan? Herbst: 1.8, believe it or not it's pretty close. Sacchet: So it's pretty much the same amount. That actually stayed the same even though you are doing a larger space? Herbst: Yes. Sacchet: That's a very good reference point. Herbst: From what I talked to you about tonight is pushing the envelope a little more. Sacchet: Right, right. What's your, do you have a sentiment about the proposal staff made that the grading towards the creek on the east side of the creek that you would stop at, what was the elevation, 756 and kind of leave the other side untouched for now? Do you think that's a good idea? Is that creating a problem? Herbst: I think that it's a catch 22. I think it makes sense because Bob Generous and Kate make a statement in there that we could still use that area but it's a product that makes it more complicated by going up vertically. Even at Edinborough and Centennial Lakes the only vertical product I had was that senior rise, that building there. That's a very tough market. People are comfortable with three floors, sometimes four, but after that it gets to be a real market grind. In fact, some of that product, the first phase of Edinborough was basically designed with some walkout to that four-story to kind of discourage the elderly from buying them because they wanted to cater to young people to keep them there. That's what Edina was lacking was housing M Planning Commission MeeQ— August 17, 2004 • for people that want to work there and I think you start pushing that product up and you lose that market appeal. Sacchet: So what I hear you say is you're OK with this for now since it's going to be calculated into the buildable area? Herbst: I don't want to see it shrink because it could come back to bite us. Sacchet: I wouldn't really shrink your buildable area. Herbst: Yes, it does. It shrinks the amount of land that would be open for buildable area... Sacchet: It does shrink. Yes, that's right. It shrinks it by 1.4 or 1.6 or something like that. Herbst: When you get old you hate shrinkage. Sacchet: So that's contrary to your aim. I understand. Are you OK with the conditions basically? The escrow amount? Herbst: The issue I've worked out with Matt, letters of credit. Most cities allow us to do development bonds and there are not as expensive but a letter of credit is very costly so I've talked with Matt. A $620,000 letter of credit up front would make Mrs. Zwiers probably have to put in escrow at a bank $620,000 cash or, if its stocks and bonds, probably $800,0004900,000 before banks can issue that letter. If we can do this in sequence of maybe a fifth of this or enough to cover each phase 110%... Sacchet: So you would like to do it in phases, sequencing it? Herbst: Yes, and the same with the trees. If we could do the trees, and if Jill could talk to the same people that I did today, too, and if we can make that kind of buy, that's a great buy for trees. ...in the future, that could get very costly if we were to have to put 38,000 trees out there. At the price of what I paid last year that could be a 1.9 million dollar deal. ...Hennepin Village. Sacchet: The last question Dan, ...(the tape was changed at this point)... stormwater. Can you give us a little bit more meat to that one? Herbst: I think most of its done except a tree survey but we have got a good stormwater plan worked out, we've got good contours for you, we've got a good storm pond system set up and I think the data that's on the site now is, we're light years ahead of where we were six months ago. Some other things we've got to do as we work on this plan with you is we've got to work out some access issues with MnDOT and that's another thing we haven't addressed. Sacchet: Alright. I think that's all the questions we have for you. Thank you very much for your presentation. This is a public hearing so I would like to invite anybody who wants to address this item, wants to add your view to it, any comments, please come forward. Any takers? Please state your name and address for the record please. 19 Planning Commission Meeo — August 17, 2004 • Spiess: My name is Mike Spiess at 470 Flying Cloud Drive. Per the map I'm actually a little bit west of what they're proposing so a lot of my questions did get addressed; however, some of the things I'm hoping the applicant would be willing to do is keep us in mind when they are moving into the western part of that because it's going to, there's a lot of dust and stuff that will be kicked up. Ideally, there are things we can do as homeowners to limit the effects to our houses. I know I've talked to my other neighbors. We don't see this as a problem. We'd like to work with them however we can, asking that they keep us in mind, too because we are existing. We aren't part of what we currently see here but we are. One of the other questions I had is on the, I know they own a little bit more land than what is currently being proposed here. It's probably only another couple of acres possibly which would be directly in front of the three houses that aren't listed here. I'm just wondering if there is anything in place for that currently. If that's going to be part of this or not. There was something else but for the life of me I can't remember what it is right now. Sacchet: Kate, do you want to just address his concern, his question? Aanenson: Again, there are conditions for grading and we do have that in here. I was just checking with Matt on that too regarding hours of operation and there are standards as part of the interim use permit and that's why there are securities so those are enforced. As far as again, the overall grading, ultimately it is the City's goal as we update the City's Comprehensive Plan which has to be done in 2008, we did provide a phasing plan and we anticipate that this area will be coming in approximately 2015. But again, we kind of go back and re-examine that. We guided the rest of this area for industrial. There are some industrial uses along 212 and we want to make sure that there is adequate access based on our understanding that if 212 gets built, this would become a county road and we want to provide access. The county doesn't want every individual driveway so ultimately, everybody has benefited, not the exclusivity of one person. We would work through those issues as we're updating the Comprehensive Plan. We want to do a corridor study and look at how all these properties connected and link to each other as we provide municipal services which would be sewer and water and road access so that discussion will be coming up again. This plan doesn't propose any development now. We're just trying to fix some other issues. Spiess: OK. And that was my other question is this is strictly grading? This is nothing else at this point? Aanenson: That's correct. Any plan that would come forward requires a public hearing before the Planning Commission. Spiess: OK. That's all I had. Thank you very much. Sacchet: Anybody else who wants to address this item please come forward. State your name and address for the record please and let us hear what you have to say. Tester: I'm Dan Tester and I live at 230 Flying Cloud Drive. I'm one of these houses, this one right here, this is where I'm at. I've been in there almost 27 years and I realize that progress 20 Planning Commission Meel* — August 17, 2004 • coming all over and I don't know, I guess I'm concerned as where my family is going to be with all this and what the plans are with my property and what's going to go on with that and also, with all the construction and stuff, I'm concerned with the quality of our living there. Our quality of our life while this is all going on too. Also, this pond here looks like its right in my driveway and I don't know how I'm going to get in and out of there. Anyways, I don't, it's been a quiet, nice neighborhood all these years or most of the years, not the last few, but I kind of hate to ... I wish it wasn't all happening. I would like to just live out the rest of my life there, get the place paid off and stay. I don't know. So anyways, I'm just concerned as to what's going to happen to my place, where we fit in. So anyways, I don't know what else to say. It's happening and it's kind of different experiences for us. Sacchet: Well, can we respond to that? Saam: I'll just suggest a couple of things and then Kate can add anything she wants. Two of our conditions were specifically meant for the two residences, the 230 and 240 residences. Access to their houses has to be provided at all times and we're talking about doing this in a phasing approach and what staff would envision is phasing plans that would show each phased approach and when he gets to the west side, if the Zwiers or Mr. Herbst doesn't have control of those properties, then those properties would have to be left out. The driveways will have to be shown how they're going to access off the proposed street or whatever so we won't forget about these residences. Sacchet: Kate, do you want to add anything? Aanenson: Part of the reason why we felt strongly about on the other side of the creek, that gives them a level of protection. The one -and -a -half acres that we talked about as we drove down that street, you can see that there is kind of a natural, topographic break, the creek and then the bluff rising up. Again, as Matt indicated, and everything behind this, if this property was not to be blended, the people on Erie, because ultimately this could be happening as one. If that doesn't happen, then we would make sure that the break was such that there's not such a severe, and obviously the stormwater pond couldn't go there. That would be phase one so I think one of the conditions that we, what we probably should put in here is that we evaluate each year kind of see where we're at as those phasing plans come forward and see if we are on task. And that would give them an opportunity, the homeowners, to see where they are and it sounds like there are some negotiations going on and we certainly would be happy to ... make sure they understand. Sacchet: OK. And I would expect that the creek area is something that we would try to preserve from every angle from the developer as well as from the City's side. Aanenson: Absolutely. Sacchet: It is not inconceivable that those properties could stay if it turns out that way. On the other hand, I'm sure there will be discussions and options explored as this moves forward. We are really not in a position to really answer your question, what's going to happen? Ultimately, you decide that because you're the property owner for that particular piece. I would expect that over time different options will become more clear as the phases come further that direction of 21 Planning Commission Mee4k — August 17, 2004 • the grading. In the meantime, you don't have the shooting next door anymore or the hauling and mining. You may have some grading. I'm not going to judge which one is better but I probably personally would know which one I prefer. The hearing is still open if anybody else wants to come forward and address this item, please do so. State your name and address for the record please. Ford: My name is Lonnie Ford. I live at 450 Flying Cloud Drive. I've only lived there for maybe three years now. My one concem is your flooding. When I moved in the river had flooded over and took out 212. You couldn't get at it. I can figure that it's still going to do that seeing how in 1965 it was way up here. Among all the wildlife issues that they've had listed for that area in the first place. This whole area that you're talking about was all deemed a wildlife refuge area. Is that null and void now? Aanenson: That area is not a wildlife... everything south of 212 is part of the wildlife refuge. It's on the south side of 212 and it's not the City's intention to provide any municipal services south of 212 because most of that is in the flood plain and this area here that would be developed, it would be above the bluff. Ford: It's clearly above. Are you having access only from 212 to these houses? Aanenson: That would be correct. Ford: And when 212 floods again, what are you going to do? Aanenson: It's the same situation that would happen... Ford: We don't have a problem getting to our homes. It's a little past that towards Lion's Tap I would say that it does flood out across 212, but that was only three years ago and the water level didn't get that high. I don't know if they called 1965 a 100 -year flood or not. I would consider that if it was going to flood again and a lot more than it did before, you are going to have some trouble. Aanenson: Sure. Again, right now the goal is to get the slope re-established and we're not looking at a development proposal but that's something, certainly as it moves forward, that we look at access points on that property. Ford: You're not drawing in a new road off of 4? Aanenson: Right now we're just using an access to get in there to mine and extract the material for this development proposal. Ford: That's my only questions. Sacchet: Thank you. It's a very good point that needs to be looked at. Anybody else want to address this item? If not, I'll close the public hearing. I thank you very much for all your 22 Planning Commission Meell — August 17, 2004 • comments and aspects of very good points you brought up. I appreciate it. Now I'll bring it back to the Commission for discussion and comments. Claybaugh: Well, certainly going out on site and reviewing the site personally, it's in dire straits of help, sooner being better. I think it's a responsible, measurable response and I'm very supportive. Sacchet: Thanks, Craig. Bethany, likewise? Tjornhom: Likewise. Except that I do want to add that I hope that as the City and developers work together they do whatever the neighbors and the homeowners during this whole process. Sacchet: Dan, anything to add? Keefe: I support the proposal. I just had a couple of questions. One is in regards to any DNR report. Would we add something like that as a condition to this in terms of any...? Aanenson: There is a 60 -day comment period. Anything that they would submit to us between now and when it goes to City Council we would certainly add that. Keefe: OK. In regards to the, I think number 30, which is the tree, the range ... I guess what we would be approving is that they are going to plant trees. Is there any more specificity around that? Sacchet: Well the condition asked for 20,000 trees..Jor 7 by 7 spacing. It's relatively specific. Aanenson: I think the clarity that the City Forester provided to the applicant was the size and species type and I think there is concurrence on that and what we were looking at is 6 to 8 inches. These are actually seedlings and that may be again put with tubes so they're protected. So I think there is concurrence on that and we gave them a price on that and I think it's significantly less than what they thought originally. Again, that breaks down based on what we can get at bulk from the DNR and they want us, this is a site that they've identified that they want to look at that... Keefe: There's a fair amount of discussion around phasing. Does that mean we would require in regards to paving or review or... Aanenson: I think you should add a condition. Saam: I do believe we tried to address that. Condition number 3. I'll just read it. It says, "The interim use permit shall be approved for a period of five (5) years from the date of City Council approval. Annually, the grading permit must be renewed. The applicant will need to request a formal extension 60 days prior to the expiration date of the permit." So what we were looking for, kind of proposing was that the entire plan would be approved by yourselves and Council and then staff would annually review a grading permit for the site unless you wanted to get into more detail. 23 Planning Commission Mee* — August 17, 2004 • Sacchet: Does that address your phasing concern? Because I was wondering about that too, personally. Keefe: I think so. Claybaugh: I have a ... question. Sacchet: Go ahead, Craig. Claybaugh: What would you see being in terms of supporting documents for that application? Saam: Sure. It would be a phased grading plan, and interim grading plan for the area they're proposing to grade and work on say, next year, they would have to supply that plan. We would have to review it based on this plan and make sure it conforms. Claybaugh: At which point you could review how it would affect neighbors, haul routes, and so on and so forth. Aanenson: Exactly. Quantities to be moved, landscaping. I think if that's something that you wanted to put on a administrative or if you want to just see that for your edification we could include that in the packet so you could see what we've issued. Claybaugh: It sounds like number 3 would be satisfactory. Sacchet: Sounds good. Anything else, Dan? Keefe: No. Sacchet: There are a couple of things and I think we all touched on them to some extent. One aspect is the tree aspect which we can't really tack to this one. That's something that we'd have to look at more in detail when more granularity for the project comes about and the concern if the DNR has anything to say. To me personally I think it's important to establish how special the tree gulf is and where it is. Is it all being touched by this project? I think that's something that should be established before it goes to Council. The phasing, ideally I would like to know a little more about it. We all know we have to start somewhere and I think you have a clear vision in terms of the direction we're going in with and we feel comfortable with that. As a matter of fact, I think it's an excellent direction you're taking. The concern from the neighbor about the flooding I think is quite significant, even though it's clearly above the flooding plain where this grading and all would take place. But in terms of the access, if the flooding indeed could make that place landlocked. I think that's something that needs to be looked at in terns of how we deal with that. The neighbors' concern, those two properties, I would think that's something to work out over time. I don't know if from a City viewpoint we can get more involved with it except that we put some protection in there in terms of access and we saw we all have a common interest in preserving the natural area, especially around the creek there. I think that's how far we can go with that from a City viewpoint. In terms of the contamination, lead contamination RM Planning Commission Mee* — August 17, 2004 • from the rifle range, I assume that's being covered by state regulations. That's not something we have to get involved as a City, is it? Aanenson: In the Phase I environmental audit of how their going to manage that. That was the other condition that... Sacchet: There is a condition for that in there? Which one is that? Saam: Condition number 5. Phase I environmental audit. That will shake out any contaminants... Sacchet: OK. That takes care of that. So the one that maybe I would like to add is the concern about establishing the tree line original growth there that needs to be looked at and I don't know whether we need to say something about the flooding of access but I think that would probably be worthwhile. I wanted to mention as something that needs to be studied. I don't think we would make it a condition but it's something that just to anchor it in that it's being looked at? Saam: Mr. Chair? Sacchet: Yes? Saam: I'm just writing down my notes. Staff, we'll take a look at 212 and those elevations. My guess or hunch is that if one and either the east side of 212 or the west side is flooded the other one was able to be passed because there are other residences around 212, not just on the south side but on the north and I guess I haven't heard of them being landlocked during, I think we flooded three years ago in 2001 so that's something... Sacchet: I think the comment of the resident was flooded further east if I understood correctly what you said so it was open to the west I presume based on what I heard you say. Ford: Yes. Sacchet: OK. Alright, so that helps. I think that's all the comments I have. I really support this. I think it's in very good hands. Very convincing presentation from the applicant's side. I want to thank you for that. With that, I'm willing to take a motion. Papke: I'll go ahead. The Planning Commission recommends approval of Interim Use Permit Planning Case #04-27 to permit grading, excavation and slope restoration as proposed on the plans prepared by Sathre-Bergquist, Inc., dated 7/16/04, subject to the following conditions as presented by staff 1 through 32. Sacchet: Actually, it's 3 through 32. Aanenson: Yes. Papke: Pardon me. It's 3 through 32. 25 Planning Commission Mee* — August 17, 2004 0 Sacchet: We have a motion. Is there a second? Keefe: Second. Sacchet: We have a second. Any friendly amendments? Papke: Friendly amendment. Sacchet: Go ahead, Kurt. Papke: Friendly amendment that we strike condition number 29 because it's redundant with condition number 16. Sacchet: That's acceptable. Alright. Any other friendly amendments? Do we want to have a friendly amendment that access concerns in view of flooding will be further studied? Papke: That's acceptable. Sacchet: And another friendly amendment that, how do we say that, further special concern will be given in case there is original growth established on the site. Papke: Kate, with that 60 -day review is that necessary? Aanenson: I guess the concern is that the DNR has additional comments that you may want to inject or did you want the Council to review those? Sacchet: Yes. That's kind of where I'm going with this. Aanenson: OK. So if the DNR does comment on any natural gulf areas you want those to be incorporated? Sacchet: Basically my intent is that question is cleared up before it goes to Council. That's really what I'm shooting for with this. Papke: If you find that necessary, it's acceptable. Sacchet: OK. So we have a motion, we have a second, we have some friendly amendments. Everybody in favor say aye. Opposed? Motion carries 5 to 0. Papke moved, Keefe seconded that the Planning Commission recommends approval of Interim Use Permit Planning Case #04-27 to permit grading, excavation and slope restoration as proposed on the plans prepared by Sathre-Bergquist, Inc., dated 7/16104, subject to the following conditions: FM Planning Commission Mee* — August 17, 2004 0 NOTE: The conditions in the staff report were incorrectly numbered 3-32 (original condition number shown below in parenthesis) but have been renumbered as 1-30. 1.

Sacchet: In summary for Council, I want to point out that we're very impressed with the applicant's vision and direction that he's taking with this. We believe this is in good hands. We went to look at the site and certainly appreciate the effort to start cleaning this up in a sensible good manner that is not just cleaning up but actually leading to what ultimately can become a very positive development for the future, a little ways out in the future. That's one of the aspects I personally have been most impressed with. To actually see how far this is thought through and then in how far the situation really reaches to become a really solid foundation for a good development at some point, not that far in the future but still decent ahead and that is also part of the value that we see that the natural environment can somewhat stabilize before that is going to take place with the significant slopes that have to be dealt with there. A very difficult challenging situation with extreme slopes, with extreme erosion, with contamination of lead, a lot of significant hurdles to overcome. We have some concerns about the impact on the natural environment but I think the applicant is very sensitive in terms of how this is being approached. The concern of the neighbors that live there in the middle, there are two properties in the middle, that's definitely something that needs to be considered, at this point kind of an exception. Whether it remains and exception or not, that's going to be up to those residents to decide. Certainly, the preservation of the creek area seems to be a common thing that everybody seems to agree that's important to maintain and we are comfortable with the aspect of phasing this in starting on the northeastern comer and then coming from the eastern side further towards the west. There is concern with exporting this huge amount, tremendously big amount of material in terms of if that's going to be affecting the traffic situation or if it's going to access 212 even with the consideration that 212 will off-loaded once the highway, the actual 212 highway is going to be built. That will certainly help. But even with that, it's an issue that needs to be looked at. A lot of these aspects will be addressed after we move forward and then see more what exactly is going to come about and we look forward to further discussion with the applicant on where this is going. Anybody want to add something to the summary? Claybaugh: I do. I would direct it to Kate. I don't know if it would be appropriate, but is there anything from the City's standpoint we can do to facilitate just in terms of the two neighbors 29 Planning Commission Meet— August 17, 2004 • specifically that they are duly communicated to rather ... it's troubling to see someone come up and appear that blindsided. Sacchet: Yes. I think that's important that we anchor that in. I would expect that certainly the applicant will work with those neighbors as the whole region clearer. Claybaugh: I recognize that the applicant has an option and it's inappropriate perhaps for him to be communicating but there certainly needs to be something facilitated for those neighbors. Sacchet: Good comment, Craig. I appreciate that. Anybody else want to add any of the highlights to the summary for Council? No? OK. With that, I thank you very much. Good luck with your project. You want to add something? Herbst: Thank you very much for coming to the site and for the... deliberations. Are you open to some of the items we looked at... Sacchet: Yes. What I would encourage you is maybe set up with staff a discussion. We do that with developers at times. We have discussions where we can talk about... Herbst: But not get into it here. Sacchet: No. I would definitely not consider that issue. As a matter of fact, I'm personally not interested in... Thank you very much. Anybody want to note the minutes? APPROVAL OF MINUTES: Commissioner Tjomhom noted the verbatim and summary minutes of the Planning Commission meeting dated August 3, 2004 as presented. Sacchet: Minutes have been noted.
