LOCATION: West side of Galpin Boulevard (County Road 117) at the intersection of Lake Lucy Road - a portion of the SW 1/4 of Section 3, Township 116 North, Range 23 West. APPLICANT: Ed and Mary Ryan Charles W. Plowe Consulting Engineer 6730 Galpin Boulevard 9180 Lexington Avenue NE Excelsior, MN 55331 Circle Pines, MN 55014 (612) 943 -1410 PRESENT ZONING: ACREAGE: DENSITY: ADJACENT ZONING AND LAND USE: WATER AND SEWER: RR, Rural Residential 37.92 Acres gross: 1.24 units per acre net: 1.83 units per acre N - RR, single- family homes S - RR, single - family home E - RR, Galpin Blvd. and single- family homes W - RR, vacant Not available. Pending Lake Lucy Road extension approval. PHYSICAL CHARACTER.: The site is partially cultivated for hay. There are severe slopes throughout the site with elevation changes from 1046 feet to 980 feet, a natural wetland in the southwest corner of the development and two ag/urban wetlands along the eastern edge of the development. There are concentrations of trees to the north and east of the natural wetland, within the wetland, along the west and north boundary of the site, and around the existing homestead. The Lake Lucy Road extension is proposed through the site. ial - - 1.2 - 4.0 units [7 Shamrock Ridge ' August 17, 1994 Revised September 1, 1994 Update 9 /21/94 ' Page 2 PROPOSAL /SUMMARY ' The applicant is requesting the rezoning of 37.92 acres of property from RR, Rural Residential, to RI F, Residential Single Family, preliminary plat approval to subdivide 37.92 acres into 47 single-family lots, 2 outlots and 7 acres of right -of -way, and a wetland alteration permit to dredge and fill wetlands located on site. Rezoning of the property to RSF is consistent with ffie 2000 Land Use Plan designation of the property as Residential - Low ' Density. The Ryans contacted the city about the prospect of developing their property when the City ' Council was determining the location of Lake Lucy Road extension. They indicated to staff that they had no immediate plan to develop, but wanted to ensure that the location of Lake Lucy Road thro gh their property works the best for development of their property. Because ' the city does not have a conceptual approval process for a subdivision, they decided to gain preliminary plat approval from the city. Since beginning the process, the applicants have revised their int rtions, stating that they will develop the property in the immediate future. This property has some significant issues involved in its development including the Lake ' Lucy Road exte ision alignment, severe slopes, grading and drainage concerns, wetlands, tree preservation, and the interrelationship of this plat with the future development of surrounding lands. Staff believes that the subdivision, as proposed, is inconsistent with the existing land ' form. The steep slopes on the western half of the development make the development of this area problematic at best based on the development proposal due to the severe slopes. From a land use and site design standpoint, this portion of the property would be better accessed from ' the north, eliminating the need for excessive grading of the site. The proposed alignment for Lake Lucy Road does not correspond to staff's preferred alignment adjacent to the wetland located in the southwest corner of the site. ' Meanwhile, Geaach and Paulson have proposed a subdivision (Brenden Pond) to the west of the Ryans. The Mancinos, who own the! 'property to the north, are also concerned about the , impacts of these developments and how their property can be best accessed. Staff asked all these property owners to meet to try and' resolve how each development is best designed. Access between and through each parcel is a critical issue and it is the city's job to ensure t that the subdivisions do not land lock other parcels. In addition, access needs to be provided in a location that takes into consideration the natural features of the land. This has been a very difficult p ocess for staff. We have spent numerous hours exploring design options. All three affected parcels have been working with the city. The Lake Lucy Road alignment is such a significant issue and impacts this and adjoining ' developments t4 such an extent, that its alignment must be resolved. The city's preferred ' Shamrock Ridge August 17, 1994 Revised September 1, 1994 Update 9/21/94 Page 3 ' alignment for Lake Lucy Road is the southern alignment. Not only does this alignment provide a community view of the open space /wetland, but it also provides better access to the required stormwater ponding areas that will be provided adjacent to the wetland, it eliminates front facing lots on Lake Lucy Road in Shamrock Ridge and the Brenden Pond development to the west, and it reduces the amount of filling adjacent to the wetland by 10 feet (private ' road elevation 998 vs. Lake Lucy Road southern alignment station 13 +75 elevation 987.93). The southern alignment provides the applicant with two alternatives for the development of the western third of the project. Alternate 1 permits two cul -de -sacs running north from Lake Lucy Road. While allowing the development to be completed on its own time, it does not minimize the grading of the western part of the development. However, it does eliminate lots fronting directly onto the collector road. The use of private roads, which permits up to a 10 percent grade, to access to the north may alleviate some of the grading that would be necessary. Alternate 2 would outlot the western third of the development north of the Lake Lucy Road alignment until access could be provided from the property to the north. The southern alternative minimizes grading, protects trees, and provides spectacular home sites at the top of the hill. However, the development time frame for this portion of the property is indefinite and dependent on the development of the property to the north. Staff has discussed with the City Attorney the possibility of requiring the applicant to outlot the western third of the property until access could be provided from the north. His response ' was that if the applicant could provide a feasible alternative for development that met code requirements, then the city could not require this area to be an outlot. Based on this decision, staff reviewed both the applicant's development proposal and an alternative providing cul-de- sacs to the north of a southern Lake Lucy Road alignment. Based on this review, staff felt that the applicant's proposal was a better alternative and would result in less grading, tree preservation along the northern property line and a buffer from Lake Lucy Road for the property to the north. Staff is recommending numerous revisions for the subdivision that will make the development ' acceptable, if not optimal, based on the applicant's proposal. While staff still believes that the southern alignment for Lake Lucy Road is a better alignment for the community, should the City Council approve the applicant's proposal, we have developed revisions that improve the development. The approximate 546 feet of open space north of the proposed alignment ( Outlot B) does offer the city some benefit from the northern alignment of Lake Lucy Road, including landscape enhancement and buffering the impacts of Lake Lucy Road from the property to the north. 1 I Shamrock Ridge ' August 17, 1994 Revised September 1, 1994 ' Update 9/21/94 Page 4 BACKGROUNID , This property is currently being used as a, farmstead by the applicant. Their home is located in the southeastern portion of the property with the remainder being farmed. Staff has met , individually with the applicant's consulting engineer and surveyor to express our concerns about the initially proposed alignment of Lake Lucy Road which bisected the site and connected to the property to the west at the northwest corner of the property. At that time, , staff advised the engineer that the preferred alignment of Lake Lucy Road was at the bottom of the slope adJ ent to the natural wetland. Staff met on August 2, 1994 with the applicant and the abutting ' property owners in order to determine the appropriate locations for street connections and to discuss the issues involved in this development. Of special concern is the Lake Lucy Road extension location and providing convenient and feasible street access to the property to the orth. Since these meetings, the applicant has revised the plat by moving the Lake Lucy Road extension first sixty feet and then an additional 20 feet south of the northern property line. On August 17, 1 94, the Planning Commission tabled the proposed development in order to permit the applicant to revise the plans consistent with staff recommendations. At that time, ' the Planning Commission appeared to be of a consensus that the Lake Lucy Road alignment be revised to the south. While meeting some of the conditions of the original report, the applicant contimied to provide a northerly alignment for Lake Lucy Road. I Staff discussed tie following recommendations with the applicant's engineer, Chuck Plowe, on Tuesday, Au ust 30, 1994. Staff believes that as a compromise, the incorporation of these recommendation as well as the other conditions of approval, would make the proposed plat acceptable. The revised plans based on a, portion of these recommendations were presented to the Planning Commission at their September 7, 1994. ' 1. Extend Jennifer Way and utilities to the north property line (James Court is only the cul -de -sa ). Condition met at time of public hearing. r 2. Provide a private drive easement for Lots 12, 13, and 14, Block 2. (If such an access ' is not fea��sible for Lot 14, Block 2, then Lot 14 should be eliminated and Lots 12 and 13 made arger.) Condition met at time of public hearing. 3. Provide 3 to 1 slope on the north side of the Lake Riley Road right -of -way in the western third of the project. May ;require the realignment of the right -of -way 20 feet to the south. Condition not met at time of public hearing. ' 1 1 Shamrock Ridge August 17, 1994 Revised September 1, 1994 Update 9/21/94 Page 5 ' 4. Align the Lake Lucy Road and begin curve to the southwest to match the alignment in Brenden Pond to the west. Condition not met at time of public hearing. 5. Provide 60 foot right -of -way for Mary Bay and Gwendolen Court. Condition met at time of public hearing. ' 6. Provide a 4 to 1 slope to access the stormwater pond between Mary Bay and Gwendolen Court. Condition not met at time of public hearing. ' 7. Combine the drainage discharge pipe for Mary Bay and Gwendolen Courts into one discharge pipe. Condition not met at time of public hearing. 9. Delete ponding area on Lots 33 and 34, Block 1 and replace with a berm. Condition met at time of public hearing. ' 10. Look at the grading for Lots 4 through 8, Block 2 to promote stormwater drainage from the front to the rear, rather than concentrating stormwater flows to the rear of Lot 4. Condition not met at time of public hearing. 11. Verify the proper sizing of the stormwater ponds on site based on the surface water ' management plan. Condition not met at time of public hearing. The applicant has incorporated additional revisions into the plat that is being presented for ' City Council review and approval. Specifically, the applicant has curved the Lake Lucy Road alignment to meet the proposed alignment within the Brenden Pond development being proposed to the west. In addition, the applicant has replaced the western most cul -de -sac with a private road, reduced the total number of lots by one to 48, and moved the northern private road outside the 30 foot conservation easement. ' REZONING The property is designated as Residential - Low Density (net density range 1.2 - 4.0 ' units /ac.). The proposed rezoning of the property to Single Family Residential is consistent with this land use designation. Staff supports the requested rezoning. WETLANDS According to the wetland delineation performed by Arlig Environmental, Inc., three wetlands have been identified on -site and they are described as follows: Shamrock Ridge August 17, 1992, Revised Septem�er 1, 1994 Update 9/21/94 Page 6 Basin 1 is the 1 ge wetland located on the western boundary of the site. extends off -site o the west; approximately 4.7 acres of wetland is on -site. classified as a natural wetland under the City's Wetland Ordinance. it The wetland , The wetland is Basin 2 is located along the eastern edge ,of the property. The wetland is approximately 0.8 acre in size. The wetland is classified as, ag/urban under the City's Wetland Ordinance. It appears that this basin will be eliminated land converted into a stormwater treatment pond as a result of the pro osed development and the extension of Lake Lucy Road. As a result, the area filled will r' uire mitigation. The Army Corps of Engineers will require mitigation for fill and excavation at a ratio of 1:1. However, in accordance to state and local regulations, a ratio of 2:1 is required. Basin 3 is locat in the southeastern corner of the site. The wetland extends off -site to the south; approxim tely 0.4 acre of wetland Is on -site. This wetland is part of a wetland complex and it ains south into Basin 1.I The wetland is classified as ag/urban under the City's Wetland dinance. Regulations A replacement lan will be required as part of the State Wetland Conservation Act (WCA) and Wetland Ci�y Ordinance (CWO) requirements. The City administers the WCA. In addition to the replacement plan requirements, staff would like the following information as part of the wetland delineation report: a map with the locations of the wetland data points, at least one data sheet for each wetland identifying upland, and a map of the soils. The Army Corps of Engineers rs will also require a permit application for the alteration of wetlands. They should be contacted for their requirements. The WCA and tie CWO require a wetland replacement ratio of 2:1 for wetlands filled. The wetland replacei nent plan should be designed to meet the existing functions and values that have been removed as a result of filling in other wetlands. It is possible to replace the wetlands at a ratio of 1:1 in upland and a ratio of 1:1 as wetland restoration. The City is going to start a__IwIetland bank in the near future by restoring wetlands that have been drained. It may be possible to purchase banking points as part of the mitigation for this site. Staff thinks that wetland replacement should occur in the large wetland to the west rather than creating a small wetland adjacent to a large stormwater pond. The WCA was prudent. Alten wetland alterati vritten to replace wetland values where avoidance of activity is not feasible or itives for avoiding wetland impacts should be considered as part of the permit process. I�j r� I. ' Shamrock Ridge August 17, 1994 Revised September 1, 1994 ' Update 9/21/94 Page 7 ' In addition, to the requirements of the WCA, the CWO requires a buffer strip and buffer strip monumentation around the wetlands. The buffer strip width required for natural wetlands is 10 to 30 feet with a minimum average width of 20 feet and the buffer strip width required for ' an ag/urban wetland is 0 to 20 feet with a minimum average width of 10 feet. The principal structure setback is 40 feet measured from the outside edge of the buffer strip. The proposed grading plan will have to show the buffer strip and the appropriate house setbacks. ' SURFACE WATER MANAGEMENT PLAN (SWMP) ' The City has prepared a SWMP that is in the final stages of formal adoption. The SWMP will serve as a tool to protect, preserve, and enhance its water resources. The plan identifies the stormwater quantity and quality improvements from a regional perspective necessary to allow future development to take place and minimize its impact to downstream water bodies. In general, the water quantity portion of the plan uses a 100 -year design storm interval for ' ponding and a 10 -year design storm interval for storm sewer piping. The water quality portion of the plan uses William Walker Jr.'s Pondnet model for predicting phosphorus concentrations in shallow water bodies. An ultimate conditions model has been developed at each drainage area based on projected future land use, and therefore, different sets of improvements under full development were analyzed to determine the optimum phosphorus reduction in priority water bodies. ' In conjunction with final platting and the construction plan review process, staff will require the applicant to supply drainage plans providing the pre - developed and post developed ' drainage areas along with runoff calculations for pre - developed and post - developed conditions. Storm water runoff from the site shall maintain the pre - developed conditions for a 100 -year, 24 -hour storm duration. Water quality ponds shall be designed and constructed in ' accordance with the Walker Pondnet model which essentially uses a 2.5 -inch rainfall. In addition, detailed drainage plans and calculations indicating drainage to individual catch basins will also be required. The grading plan shall also reflect the normal and high water ' elevations in the wetlands and storm water ponds for both pre - developed and post - developed conditions. Water Quality The SWMP has established a user fee for water quality systems. The cash dedication will be equal to the cost of land and pond volume needed for treatment of the phosphorus load leaving the site. The requirement for cash in lieu of land and pond construction shall be based upon a schedule in accordance with the prescribed land use zoning. Values are calculated using the market values of land in the City of Chanhassen plus a value of $2.50 per cubic yard for excavation of the pond. If the applicant constructs the water quality basins, these fees will be waived and credit given for any oversizing. Shamrock Ridge August 17, 1994 Revised Septem)er 1, 1994 Update 9/21/94 Page 8 Water Ouantity The SWMP has established a user fee for different land uses based on an average, city-wide rate for the insullation of water quantity 'systems. This cost includes all proposed SWMP trunk systems, culverts, and open channels and stormwater ponding areas for temporary runoff storage. Single-family residential developments will have an assessment rate of $1,980 per acre. The proposed development would then be responsible for a water quantity assessment fee of $63,360 assuming 32 acres of developable land. The City will apply credits to the applicant's surf ce water quantity fees for construction of improvements in accordance with the SWMP whilh include such items as outlet control devices, trunk storm sewer pipes, ponding, etc. The exact fees will be determined after final review and approval of the construction plans and specifications and Lake Lucy Road assessment methodology if applicable. DRAINAGE The development is located within the Lake Lucy Watershed. The SWMP should be reviewed by the applicant's engineer and the site designed in accordance with the SWMP design to the extent feasibly possible. All runoff shall be pretreated before discharge to any of the existing etlands. Similar to Brenden Pond, Lake Lucy Road will intersect this parcel. The applicant's plans have included a segment of Lake Lucy Road; however, it does not correspond to the City's feasibility study. The Lake Lucy Road alignment is shifted northerly to facilitate two cul -de -sacs on the south' side of Lake Lucy Road adjacent to wetlands. A storm water retention pond to pretreat runoff from the cul -de -sacs and part of Lake Lucy Road is proposi A adjacent to the wetland. Another storm water treatment pond is proposed adjacent to Gal in Boulevard lying both inorth and south of Lake Lucy Road. Staff has recommended w the applicant's engineer to delete the southerly pond and extend storm sewer to the existing �ulvert underneath Galpir Boulevard.

Another one is located just northerly of the wetland areas. as proposed constructing two of the three ponding areas. The SWMP also 1 71 L �I �J ' Shamrock Ridge August 17, 1994 ' Revised September 1, 1994 Update 9/21/94 Page 9 ' proposes a third water quality basin at the end of the ravine in the southwest corner of this development and extends westerly into Brenden Pond. It may be feasible to consider ' combining the proposed pond between Gwendolen Court and Mary Bay with the proposed SWMP pond in the southwest corner and Brenden Pond. This area then could be utilized as a mitigation area. The applicant may be given credit for the oversizing of the storm water ' treatment ponds and any trunk storm sewer facilities they install in conjunction with the overall development. This will be further reviewed upon the final plat and construction plan and specification review process. Staff encourages the applicant's engineer to review the City's SWMP plan for appropriate sizing of the ponding areas and trunk storm sewers. The storm ponds should be designed with access in mind. A 4:1 side slope is required along/over the storm pipe which discharges into the pond. The pond should be designed and constructed ' with a 10:1 bench at the normal water level (NWL) for the first one foot (depth) of water and the remaining at 3:1. Another alternative would be to design the pond with 4:1 slopes overall. ' The plans have combined the storm sewer lines from Mary Bay and the westerly private driveway. However, staff is not satisfied with this proposal from a maintenance standpoint and believe better alternatives exist. Staff is confident with the upgrade of Lake Lucy Road and prior to final plat approval, this issue can be resolved. GRADING The site contains very steep slopes in the northwesterly portion of the site as well as a small ravine area. The slopes along the northerly portion are in the range of 20% to 30 %. With these types of slopes it is very difficult to prepare a site for streets and house pads without significant grading. Staff has reviewed the plan and has prepared a few options with what we believe would be a more feasible approach to developing the steeper part of the site (westerly 1/3). We believe if the parcel to the north (Mancino) was to develop prior to this development we would require that a street be extended to the northerly line of this plat for a future cul -de -sac to extend lots off of this high ridge. This would make use of the existing topographic features of the property without substantially altering the grades. This would also ' allow for Lake Lucy Road to be extended along the southerly portion of the site to maintain a sufficient buffer and setback below the proposed homes along the northerly portion of the development. It would also allow for sufficient wetland mitigation and storm water treatment ponds adjacent to the wetland. One of the drawbacks with regards to this approach would be the lack of benefit that this development would receive from Lake Lucy Road. It is the City's intent to partially assess the benefitting properties for the construction of Lake Lucy Road; however, in this segment where no direct benefit is received the City would have difficulty assessing a portion of Lake Lucy Road. However, the City may have alternative 11 Shamrock Ridge August 17, 1994 -I Revised Septe 1, 1994 Update 9/21/94 Page 10 financing methods such as State Aid to assist in developing the roadway system. Unfortunately, t4ese funds are encumbered for the next three years. The grading plan as revised with the Lake Lucy roadway alignment to the north has flattened the backslopes ftom. 2.5:1 to 3:1 with a boulevard area. The plans have also realigned Lake Lucy Road in art attempt to be compatible with Lake Lucy Road proposed within the Brenden Pond subdivision directly to the west. This should be made a condition of approval should this alignment still need to be adjusted. In addition, this alignment will not match with the development to a west ( Brenden Pond). Staff has been working with the applicant's engineer in realigning Lake Lucy Road to match to the west and provide appropriate boulevards and )ackslopes. This appears to have been achieved by slightly curving Lake Lucy Road southwesterly and shifting the street southerly. Lots 4, 5 and 13, Block 4 are proposed to be serviced off a private driveway off of Jennifer Way. The plans propose a street stub north towards the Mancino's. from Jennifer Way. The street could terminate at a point short of tt a tree line which would provide access to the last Lots 3, 4, 5, and 6, Block 4 and future exterision to Mancino's if desired. Staff is concerned with sight lines when exiting the westerly private driveway onto Lake Lucy Road due to a proposed berm. Staff recommends that the berm be relocated westerly to improve sight distance. The applicant is proposing water quality ponds adjacent to Galpin Boulevard. Galpin Boulevard is classified as a local collector street and will need additional right -of -way dedicated with this plat. According to Carver County, a minimum corridor of 100 feet should be reserved for uture upgrading to a four -lane street. The applicant is to dedicating an additional 17 fe t of right -of -way along Galpin Boulevard to fulfill the County's requirement. The backyard drainage from Lots 1 through 11, Block 3 will be directed to a wetland located in the southeast corner of the site. An interim sediment pond is proposed to treat runoff prior to entering the Staff is concen directs runoff e the applicant's drainage patter. yards to addres the grade to pr the home will 1 UTILITIES The sediment pond may be removed once the lots are revegetated. d about the grading behind Lots 4 through 8, Block 2.

Staff has recommended to igineer that this needs to be revised to promote a rear yard to front yard The engineer has proposed a storm sewer to convey runoff from these rear this. However, staff still encourages the applicant's engineer to rear design note a back to front drainage pattern. If the catch basin becomes plugged, subject to flooding. 0 1 ' Shamrock Ridge August 17, 1994 ' Revised September 1, 1994 Update 9/21/94 Page 11 ' As part of the City's Lake Lucy Road extension, the utilities will be brought to the intersection of proposed Pond View Court and Lake Lucy Road approximately 400 feet west ' of this development. Utilities are proposed to be extended along Lake Lucy Road. However, since there will be a gap between the plats, it will be necessary for the City and/or developer to extend Lake Lucy Road to service this development. Without that project, this development is premature. Staff has reviewed the access and utility service needs to the Mancino parcel and believes it is prudent, at this time, to require extension of utilities and street access north along Jennifer Way to potentially serve a portion of Mancino's. The applicant has extended Jennifer Way with utilities north for future service of the Mancino parcel. J F� L The existing home on Lot 14, Block 3 (Ryan's) is currently on a septic and well system. The house should be connected to the new sewer line within 30 days after the line becomes operational. The well may be utilized as long as it is on the same lot and functioning properly. Once the well fails or the property owner sells, the property shall be required to connect to city water per city ordinance. EROSION CONTROL The applicant will need to develop a sediment and erosion control plan in accordance with the City's Best Management Practice Handbook (BMPH). Type III erosion control fencing will be required around all wetlands being preserved. The steep slopes may also require some form of terraced erosion control fencing. The plan shall be submitted to the City for review and formal approval. The City has adopted a Best Management Practice Handbook which the applicant can purchase from the City at a cost of $25 to assist with the design process. STREETS Access to the development is proposed from Galpin Boulevard (County Road 117). Another access will also be extended from the west if the City continues with the extension of Lake Lucy Road. Lake Lucy Road may be built under the City's improvement project program if so petitioned by the applicant and authorized by the City Council. Lake Lucy Road is considered a collector street based on the City's Comprehensive Guide Use Plan. It is also part of the City's Municipal State -Aid Route. According to the City's subdivision ordinance, direct driveway access onto a collector street should be restricted or controlled whenever feasible. No lots are proposed to have direct access onto Lake Lucy Road. The alignment of Lake Lucy Road west of this development has not been finalized. The City has prepared a feasibility study for the extension of Lake Lucy Road from Trunk Highway 41 Shamrock Ridge August 17, 1994 Revised Septemt Update 9/21/94 Page 12 1, 1994 to Galpin Boulevard. There are two other parcels of land that are directly impacted by the future alignment of Lake Lucy Road. The first parcel is located just west of this development and proceeding ahead with a preliminary plat (Gestach parcel - Brenden Ponds). The other parcel ( Mancino) is located to the north of this development. Staff has reviewed with the property owners several options for access to the Mancino parcel from the Brenden Pond development an this development. Brenden Pond will be providing the Mancino parcel access to the we terly portion via private driveway. Staff has also met with the Ryans to discuss two pot( itial alignments for Lake, Lucy Road which impact this development. There is no clear -cut alignment of Lake Lucy Road that satisfies all of the property owners in this situation. The preliminary plat of Shamrock Ridge has utilized a northerly alignment of Lake Lucy Road thro gh their parcel. Staff has reviewed this preliminary plat and is unclear from a design standpa int if Lake Lucy Road will be compatible with the plat to the west (Brenden Pond). Staff has also reviewed the southerly alignment of Lake Lucy Road through this parcel which leaves the westerly portion of the site very difficult to develop due to very steep slopes. However, this alignment works well with the existing terrain and minimizes impacts to the wetlands. The resulting impact from the southerly alignment of Lake Lucy Road requires short, seep cul -de -sacs as well as tuck -under type homes to the north of Lake Lucy Road unless access is from the north (Mancinos). Staff still believes that the southerly alignment is the preferred alignment for Lake Lucy Road. The applicant is proposing to dedicate an 80 -foot wide right -of -way for the construction of Lake Lucy Road through the development. The plans also propose a 60 -foot wide right -of- way on all the s xeets and construction of the City's standard roadway section for the interior streets. Street grades range from 0.5% to 7% which is the City's maximum grade allowed. Detailed constru aion plans and specifications for the street improvements will be required as part of the final plat submittal. Access to the Mancino parcel shall be provided by extending Jennifer Way to the north of James Court and conditions stipulated in the development contract that this street may be extended in the future. A temporary cul -de -sac will be necessary at the end of Jennifer Way. No additional easements will be necessary and the turnaround can built within the proposed right -of -way. Conclusion Staff has reviei Lucy Road) shy northerly Lake with the inters( to provide acct parcel and still an appropriate I this plat submittal and still believes that the southerly alignment (Lake d be followed. However, as a compromise, staff would be open to a cy Road alignment if the applicant can revise Lake Lucy Road to match on proposed in Brenden Pond. Jennifer Way has been extended to the north to the Mancino parcel This leaves development flexibility to the Mancino ows both parcels (Brenden Pond and Ryan) to develop. Staff believes it is y to develop the westerly one -third of the Ryan development by accessing I l_ '1 d u ' Shamrock Ridge August 17, 1994 ' Revised September 1, 1994 Update 9/21/94 Page 13 ' from Mancinos. Due to steep grades, we believe that this site should be accessed from the north to retain its topographic features. H the Mancino parcel was the first to be developed, ' we would recommend that the Mancinos provide a street access to the south for development of this area due to the steep grades. Similarly, staff has required the Ryans to provide access to the Carlson parcel (south of Jennifer Way) due to the isolated parcel of land (surrounded ' by wetland). We feel that it is in the best interest of the City and property owners to make a development proposal which utilizes the existing topography. ' LANDSCAPING/TREE PRESERVATION A landscape buffer shall be required along the length of County Road 117, Galpin Boulevard, ' and along both sides of the Lake Lucy Road extension, section 18 -61 (a) (5). This buffer landscaping shall be developed as part of the preliminary and final plat submittal for city approval. Appropriate financial guarantees acceptable to the city shall be required. A 1 woodland management plan must also be prepared as part of the platting process. In addition, a landscape plan including the landscape buffer and forestation and replacement planting must be prepared and approved by the city. The choice of species in the preliminary landscaping plan are appropriate and acceptable, but small monocultures of trees have been created by grouping the similar species. Mixing a variety of species allows for diversity within your urban forest, thereby, increasing the overall health of it and reducing the chances of widespread outbreaks of disease. Symmetry along boulevards need not be lost by using diversity. Aesthetic avenues can be attained without the disadvantages associated with ' monocultures. Choosing trees of different species that will attain similar heights or have similar branching characteristics is an excellent alternative. ' The landscaping plan requires an additional 42 trees based on staff's analysis of the tree preservation, forestation, and replacement requirements for a total of 284 trees. Staff recommends that the additional 42 trees be incorporated in the landscaping plan as follows: 1. Nine trees staggered for a windbreak along the western property lines of Lots 1 and 2, Block 1. Windbreak trees shall include spruce (Black Hills, Norway, White). ' 2. Five trees grouped near the corners of Lots 4, 5, and 6, Block 1; 10 trees grouped along the rear lot lines of Lots 8, 9, 10, 11, and 12, Block 1; and 18 trees in groupings along the rear lot lines of Lots 2 through 11, Block 3. Rear yard tree selection shall be River Birch, Ohio Buckeye, Catalpa, Silver Queen Maple, White or Bur Oak, Hawthorne, Aspen, Arborvitae, and Balsam or White Fir. 1 In addition, the following tree conservation and forestation areas shall be dedicated as part of the final plat: a 30 foot easement along the northern boundary of the site; a thirty foot !J Shamrock Ridgel ' August 17, 1994 Revised September 1, 1994 , Update 9/21/94 Page 14 easement along Ihe western lot lines of Lots 1 and 2, Block 1; the southern 100 feet of the ' eastern 30 feet o Lot 4, Block 1; the southern 30 feet of the western 30 feet of Lot 5, Block 1; the northern 70 feet of the western 30 feet of Lot 6, Block 1; the eastern 30 feet of Lots 8 , and 9, Block 1; a western 30 feet of Lots 10, 11, and 12, Block 1; the eastern 30 feet of Lots 2 through 7 , Block 3; and the western 30 feet of Lots 8 through 11, Block 3. (Note: only the 30 foot easement along the northern property line is a conservation easement. The , remaining easement areas are for forestation and replacement purposes.) To provide slope stabilization north of Lake Lucy Road on Outlot B, Sumac shall be planted 7 feet on center. Such plantings shall be 'staggered to provide better stabilization and aesthetic appeal. Additionally, this areas ;must be mulched and seeded after grading. As P P ro osed, th re is very little tree preservation being done except for within the wetland ' area. Staff does not concur with the applicant's designation of trees to be saved. By viewing the landscaping plan and the grading plan, it is obvious that some of the trees in Lots 2, 3, 7, and 8, Block 1, Lots 2 and 3, Block 4, and Lots 6, 7, 9, and 13, Block 3 will not be "saved." Staff estimates tiat approximately one -third of the existing tree canopy is being preserved. In reviewing the applicant's tree preservation plans and baseline canopy coverage calculations, staff believes that the calculations are in error. In reviewing the tree plan, staff estimates that there is a 13 percent baseline canopy coverage (4.25 acres or 185,346 square feet in 32.63 acres of net developable land). Tree canopy within a designated wetland is excluded from ' calculation. The required post development canopy coverage is 25 percent or a total of 8.16 acres of tree c dopy. To meet the minimum canopy coverage requirements, the developer would need todvelop a forestation plan for 3.91 acres (8.16 - 4.25) which would require the planting of 156 gees (3.91 x 43,560 / 1,089). In addition, because the developer is removing canopy coverage that is required to meet their minimum canopy coverage, they must replace the removed c opy area at a rate of 1.2 times the canopy coverage area being removed. , Since the applic t did not provide these calculations, staff has estimated that the removed canopy coverage area is approximately 116,546 square feet. The replacement planting is then calculated at 13,855 square feet (116,564 x 1.2). The number of trees required for replacement planting is calculated at 128 (trees (139,855/1089). The total tree planting requirement as Fart of the development's'lorestation and tree replacement plantings is 284 , trees. PARKS AND RECREATION I The Park and R creation Commission met on July 26, 1994 to review this proposal. The Park and Recreation Commission recommended that the City Council require the following , conditions of ap�roval in regard to park and trails for the Shamrock Ridge plat: Shamrock Ridge August 17, 1994 Revised September 1, 1994 Update 9/21/94 Page 15 1.

WETLAND ALTERATION PERMIT Wetland Alteration Permit (Section 20 -407) 1 When approving a wetland alteration permit, the following principals shall be adhered to: I 1. Avoiding the direct or indirect impact of the activity may destroy or diminish the wetland. ' Finding: The applicant is proposing to fill a small perched wetland on the eastern end of the site. This wetland is isolated and has been altered in the past during agricultural practices. The applicant will be required to mitigate the wetland either through the enhancement of a wetland within the site or another within the watershed district as part of the city's wetland banking system. 2. Minimizing the impact by limiting the degree or magnitude of the wetland activity and its implementation. Finding: The applicant is proposing to fill a small perched wetland within the required alignment for Lake Lucy Road extension. This wetland is isolated and has been altered in the past during agricultural practices. The proposal minimizes the impact of the development while at the same time replacing and enhancing the wetland complexes. 3. Rectifying the impact by repairing, rehabilitating, or restoring the affected wetland activity and its implementation. � I Shamrock Ridg August 17, 199 Revised Septen Update 9/21/94 Page 20 1, 1994 Finding: The proposed wetland mitigation is to enhance and restore the natural appearance and the quality of the wetlands on site or within the watershed. Water quality ponding will be provided to filter stormwater prior to entering the wetland. 4. Reducin or eliminating the impact over time by preservation and maintenance operations during the life of the activity. Finding: The proposed alteration's will benefit the proposed development in the area by creating an enhanced and restored natural environment. Through the enhancement and long term protection of the remaining wetlands, the city is implementing its stormwater plan as well as improving the natural environment. Water quality ponding will be provided to filter stormwater prior to entering the wetland. 5. Replaces unavoidable impacts to the wetlands by restoring or creating substitute wetland veas having equal or greater public value as set forth in Minnesota Rules 8420.0530 to 8420.0630. Finding: The development's improvements will enhance the drainage facilities within the area and will be served by the appropriate public facilities. The applicant is proposing to fill a small parched wetland within the Lake Lucy Road extension alignment. This wetland is isolated and has been altered in the past during agricultural practices. The proposed wetland mitigation is to enhance and restore the natural appearance and the quality of thel wetlands in the area. Water quality ponding will be vrovided to filter storm water.

' Shamrock Ridge August 17, 1994 Revised September 1, 1994 Update 9/21/94 Page 21 The Planning Commission treated the entire development approval, rezoning, preliminary plat, and wetland alteration permit, as one package and therefore denied each element of the approval. The following issues were the basis of the Planning Commissions recommendation for denial: 1. Lack of sensitivity to the surrounding community. 2. Lack of environmental sensitivity: e.g. excessive grading, minimal tree preservation, 1 alteration of natural land form, not taking advantage of the natural assets of the land, and elimination of natural resource corridors. 3. Failure to incorporate primary location for Lake Lucy Road, i.e., the southern alignment. 4. Potential alternate site designs that could better protect natural amenities such as vegetation, wetlands, steep slopes, and water courses pursuant to Section 18 -60.

Scott: Questions? Harberts: I just have a point of discussion. You know I certainly respect the amount of time that staff and the applicant put on this. I know it takes a lot of work on the staff's time ' and I respect the time that the people have taken to come here to make comments. I feel, I guess I'm just looking at, in terms of time and good use of time, with all of those issues and not really having a complete packet. I guess I'm a little concerned about spinning my wheels because I don't know, I see some of these aren't maybe requirements with regards to lots. Things like that. I don't know if that's then going to change this drastically and it's gust, I guess I just don't like spinning my wheels with other things going on with my time. But anyway, that's just a point of discussion. Scott: Okay. Can I just ask a question? How many residents are here for this particular issue? Okay. Well we are scheduled to have a public hearing and we will have a public hearing. 24 Planning Commission Meeting - August 17, 1994 ' Aanenson: Can I make a point of clarification? Scott: Sure. , Aanenson: We ! ad the same issue at staff. These are three properties are very, very complex. The r anon we put it on, even though there's a lot of issues unresolved, we need to give them some direction... We came forward with our recommendation. There was no concurrence so 1 ve felt the best thing to do was to put it in front of the public and give them , some marching rders so they know so they're not spending their time ... so we are trying to make that, give them some clear direction on where to go with their plat so that's... Harberts: That's a good point. Thank you Kate. ' Scott: Okay, g iod. ' Harberts: I still think I'm spinning my wheels. , Scott: Okay. A ny other questions from the commissioners for staff. Would the applicant like to make, or their representative like to make a presentation? Please state your name and your address. Chuck Plowman: My name is Chuck Plowman, the project engineer representing the Ryans. Mary Ryan is he re this evening if there are any questions that I am unable to answer. Ed would have loved to be here but he was involved in an accident and he's still recuperating so he's not able to attend the meeting at this time. Let me start with just a little bit of the project background. nd. Lake Lucy Road, can you just put that map up there that shows the outlot. I'd like o see the one where Lake Lucy Road ends... specifically to give the Ryans an opportunity to evaluate their plat. See what might be most feasible and practical and ... involved mrith the properties. So we've been spending the last 3 months going over , different plans and different options and looking at exactly that. So what I'd like, I gave Dave a copy of something yesterday which is a modification for a lot of the things that we're talking about to ' ight and I think if you could just bear with me, I'll shed some light on a lot of things involved with bringing up some major issues. Let me just start with, the initial plat was submitted,'et me call it Plan A showing Lake Lucy Road up at the top. Staff told us that this was no ' a good plan because of ';the impacts on the environment and the excessive grade, actual gr�ding up into the property north of us. So we came back with trying to address those c ncerns. We did another plan, without much input from staff but just giving some, they gav ' us some direction and we just come up with a second drawing that we submitted to th4m prior to the last scheduled meeting that we were going to be on. That showed Lake Lucy coming right down the center of that corridor. And what I liked about , 25 1 Planning Commission Meeting - August 17, 1994 this one so much was that it was the most sensitive to the environment. ...all the trees along the north. Gave us long lots this way. Long lots this way. Stayed out of the wetlands. It was just the most favorable as far as environmentally concerned. It gave us some nice walkout lots here and some liveable lots here because we've got a lot of room in the back to do some grading. This was bumped down because staff said that we don't want all of these driveways connecting to Lake Lucy Road. So that brings us to the plan that we have before you tonight. This is almost identical to the one in your packet but there was a couple things done to it to address some issues ... Here we're 60 feet south of the property line with the beginning of the right -of -way of Lake Lucy Road. That enabled us to construct the road width along... boulevard and also a 3 to 1 slope and if we do get into the trees, it's very, very minor. And it also allows us to have two cul -de -sacs, one to the south and some very desirable lots looking over a wetland. This is what we're really studying the entire plat for what's economically favorable to the plat and also what's favorable to the environment. So we've come up with this plan. We are not encroaching on the wetlands. We're not taking out the trees. We're coming up with a favorable plan for development and we feel this is the plan that's best. Let me just talk a little bit about this. This is with the Lake Lucy Road going with this original alignment to the south. With the cul -de -sacs going to the north. We end up with tuck under lots. Two for sure, possibly more. We end up with destroying another tree ... because of the elevation of the road. The slope will require some wetland ... so this one's not favorable from a development standpoint. It is definitely not favorable from the environment standpoint. Let me just back up a little bit to the staff report. Let me just talk about Options A, B and C. Option A I believe was the one I just showed you. Option A was the... Okay, I really just went over that and described to you why that's not a good choice. Option B, which is the one that we just talked about, which we like. As far as the location of Lake Lucy Road. Option C is not at all favorable to the Ryan's because it's going to, this number of lots are going to be getting up here plus they're ready to develop now. They want to develop now. And initially we had hoped when we started a few months ago, they were looking only at the alignment and wanting to get some location or connecting point set. That has changed. They spent the money to have all this work done, and research done and they've got a different mind set. They do want to develop. They don't want to wait 2 years, 5 years, whatever. So they're here. They're here to get your approval so they can develop. So Option C is not a good option. And I was understanding it also is not very good for the future plans for a cul -de -sac to come down into this property through the trees so that to me would be another reason to not go with that one. Let me just touch on some of the issues. I know Dave's aware of some of them that I addressed. Things have been happening so fast. I get a short notice about some things that need attention and then Dave gets a short time to look at it so again, it's kind of works both ways. The 300 foot spacing from Galpin Blvd to the first street. The initial thought by staff was that this was going to have a ripple effect. It's going to change all these intersections. When in fact it didn't. This intersection moved I figure about more like 100 feet. 110 feet or something like that. But 26 Planning Commission Meeting - August 17, 1994 ' this one really didn't change all except for that moving over making these lots deeper and these were ex= sive before so they fit the plan. What we did also with that is, instead of having, see how the street is moving up and in fact it's going to the right. Once we switch , this street over, t was not workable doing it that way. Now we had a previous plan that showed it coming this way so this is going back to that plan ... Plan B so we kind of referred it 1 d think t k h be W did 1 another lot. N back to that on phis plan and it works much e did Generous: 75. Chuck Plowman: Yeah, so 10 %. We do have the issue of these lots fronting on Lake Lucy Road. The idea, of private drives is real negative for the same reasons that were mentioned before because who wants to live with a private drive, even if it's facing out, a private drive between these Domes is just not good. And we certainly don't want to do that. I guess what , I would like to task is that separation would be given a common drive for 2 of them instead of one for each bause I know the city does allow access to collector roads where there's not a good alternativ i. I think this is the case. where there is not a good alternative. We've done 27 1 ano er o ow we're down to major 19. We're moving in the ;wrong direction. So I guess the effect of the 300 feet was not a issue, and I know that's ... not only your's but mine. But that , wasn't-everything stayed the same... Along with this reconfiguration right here, the 17 foot by the way was also added to Galpin. The wetland setbacks. There was a drafting error on a couple lots which showed this pad down (here so it was ... and was obvious that it was too ' close to the we and but when in fact there is room there so that's not... The storm water treatment ponding area was also an issue'and before we turned the configuration things, we had no choices where the inlet and outlet was going but since then we reconfigured this, which allowed us to construct a pond in this fashion. And also discharging the storm sewer at this end of th pond. Outlets at this end of the pond. We have plenty of volume. As you can see it's quite large. So we do have an ideal situation with the discharge and the outlets ' being offset into the pond and that's what Dave was looking for. Something in that fashion. On the wetlands itself, can you differentiate between the green and the yellow? Okay, the yellow is actuary fill that's going into the wetland. This area is not filled because we're actually excavating in here. But wherever fill is taking place, you have to follow rules to mitigate for that. shy of being 2 tb The green areas are mitigation areas. And those areas sum up to a little 1. So we need to confer with Diane about what our options might be. , There's no cred�t given for storm water ponds according to the rules, even though we're creating wet pods, it doesn't apply for mitigation. The option I was looking at was ... the cul- de -sac a little bit. Reducing the fill so if'is workable because I did ... find where I can do that. ind Lower it down reduce the ... that 2 to I ratio. Time is running short so this is what I came with. I looked t the canopy coverage, because that was one of the things that they were looking for, anc I count 10 %. So there was an error made by one of the fellows ... came up , with, what was it? Generous: 75. Chuck Plowman: Yeah, so 10 %. We do have the issue of these lots fronting on Lake Lucy Road. The idea, of private drives is real negative for the same reasons that were mentioned before because who wants to live with a private drive, even if it's facing out, a private drive between these Domes is just not good. And we certainly don't want to do that. I guess what , I would like to task is that separation would be given a common drive for 2 of them instead of one for each bause I know the city does allow access to collector roads where there's not a good alternativ i. I think this is the case. where there is not a good alternative. We've done 27 1 Planning Commission Meeting - August 17, 1994 real well in keeping everything off ' p g ryth g o Lake Lucy Road. I thu�lc this is a piece of property that', ' no matter how you slice this up, it happens. You can't get away from it. Again I think I'm just going to reiterate but I feel this is the best plan. This is the plan we want and we want you to consider this for approval tonight contrary to what staff is recommending so all the ' actions from here are taken into account with some items I've clarified and addressed. Not to make it any lighter, I wanted to also mention the fact about the potential of using 50 foot right -of -ways. Staff discussed with us ... about doing that. I forget which layout we were ' looking at. But the advantage to 50 foot right -of -ways, for example here. We could use the 10 feet and pull this right -of -way in. Along with that we pulled the grading slope 10 feet in. It's a plus as far as... 60 foot right -of -ways are really something that have been used for many ' years and more and more we're going to 50 because the utilities are now going in a common trench so we don't need that room we used to have in the boulevards and the easements that they used to have for gas, telephone and electric. They're all going in one trench so the 50 foot right -of -way's working well. We can live with the 60 but I think if it's possible, we'd like the 50. I really had no further comments unless there's any other questions, I'd be happy to answer them. ' Scott: Good. Any questions for the applicant? ' Harberts: Could you just take one more minute and just kind of resummarize why you prefer the alignment of Lake Lucy? You know your preference as to why again. ' Chuck Plowman: Sure. This location of Lake Lucy Road was pulled away from the north property line so that we could preserve this tree line along this north property line, and I know the Mancino's are very concerned about that and... So this location allows us to build a ' road with the boulevard and ... it's very tight but I'm saying we can get ... in here and preserve the boulevard and save trees. On the other side, we're not encroaching onto the wetland with ' any fill. We do have a nice location here for a treatment pond and discharging runoff before it goes into the wetland. As far as the talk of there being mass grading, I've been involved with a few sites that are like this. There's going to be mass grading, I don't care how you look at it. And it's not a problem. You know we need to be sensitive to the trees. The wetlands. We can move a lot of dirt. It doesn't cost that much when it comes to developing land. I mean it's, there's a limit obviously but this isn't a problem as far as, you know if you move 2 feet of dirt, the tree's gone. If you move 10 feet, the tree's gone. It doesn't make any difference. ' Harberts: Thank you. Chuck Plowman: Do you want to hear the reasons why I don't like the other one? 28 Planning Commission Meeting - August 17, 1994 ' 1 Harberts: No. I got those down. I just wanted to again, just make sure I clearly understood the preference of why on that one. Thank you. , Chuck Plowman: Well obviously from a: developer's standpoint, we have lots that we can sell for a good price. If we put the cul-de -sacs up to the north, we lose lots or value. , Scott: Good, any other comments or questions? Good, thank you sir. This is a public hearing and can I have a motion please. ' Ledvina moved Nutting seconded to open the public hearing. All voted in favor and the motion carried. The public hearing was opened. ' Scott: The public hearing is now open. If you'd like to speak about this particular item, please step forward and give us your name and your address. Don't all stand up at once. ' Thank you sir. Steve Buresh: Steve Buresh again from 6651 Galpin Blvd. One small question. Now this is , also a proposed approval of a preliminary plat drawing for the area. Scott: Yeah. i d then a rezone from RR to RSF. Steve Buresh: light. Well that in fact is what I had the biggest problem with. This particular asking, for, which I guess has been revised down to 50 now, single family homes, i may fit in with the residential single family but the residential single family rezone does not fit in with this area at all. The area is large lot. The lots on Lake Lucy Highlands area are 2 1/2 acres. That 's probably some of the smallest lots in the area. And I think that if we , allow it to be subdivided as it is currently, we're totally going to destroy the look of the area. That's probably something that we want to attain at some point. I think we have to strongly , look at the people that are in the area now. What their wants and needs are but also consider the future obviously. We can't have all this land if it's not going to be developed at some point in time. That's just not feasible to believe that that can happen. But I guess my recommendation is not to rezone it as residential single family but in fact keep it as rural residential and work out some kind of agreement like we've done in the Lake Lucy Highlands area and I guess I wouldn't see a problem with it being even 1 1/2 acres per lot. This would fit, still fit in �th the aesthetics of the area and this particular location of this proposed development is fight in the middle of the' deer migration path. I know in fact because I wake up every morning and have deer crossing' my property. They go right into this area. This is going to destroy the wildlife in the area, but I'd like to reiterate that it's just destroys the aesthetic value of that area. So I strongly recommend that you do not rezone this as residential singl� family. Thank you. 29 1 ' Planning Commission Meeting - August 17, 1994 ' Scott: Okay. Kate, RSF. 15,000 square foot lots. This is approximately what, averages 20. ' Generous: 22. Scott: 22, okay. The reason why I brought that up is that, and this has been guided in our comprehensive plan as a RSF area. What the applicant could have done is put in 15,000 square foot lots and would have met the minimum requirement for lot size in a residential single family. So we feel that this is preferable. It's beyond what the minimum would be but your comments are appreciated. I think that development is going to happen and basically what we see, our position is that we try to get the best that we can for the city and it's very rare and I think since, in the last 2 years that I've been involved here, I don't think ' that we've put through a development that met the minimums. I don't think we really accept the minimums. We try to encourage better but no, you're comments are well taken because you know you're used to a certain type of lifestyle and what we're trying to do is trying to manage the land use as best we can but they always have to be subject to the ordinances that we deal with but thank you very much. Would anybody else like to speak at the public ' hearing? Yes sir. Peter Davis: Yes, I'm Peter Davis, 6640 Galpin Blvd. Could I ask that that map be put back ' up which showed the two different properties. I wanted to speak to several items, specifically I was encouraged to hear that there is a concern over the aesthetics and the ambience of the area. We just recently moved into the area. We knew that this development was about to ' take place. What I wanted to point out, and since some of you have started to walk the property and is generally aware of the aesthetics and what some of the unique features are. This gentlemen spoke of some of the migratory habits. There are a lot of ecosystems that are ' really coming into play here. Not only the deer but we have snow owls and bat populations. Pheasant runs that are taking place from across Galpin Lake Road where actually coming up from other wildlife areas to the northeast coming through this property and out into these ' wetlands and then going and spreading out back across Galpin in both directions. So what I wanted to point out was the fact there are actually quite a number of different ecosystems, both plant and wildlife that are going to be impacted by this development with all of the rapid that has been taking place in Chanhassen. I think it's very important that there's some considerations being made. We're very encouraged by the Mancino's efforts to set up some buffer zones and we would like to recommend that you actually consider some of the other teffects of grading, as I understand it, some of the mitigation land that would enable some of the protection for these migratory pattems that exist and cutting from the northeast to the southwest. Secondly I wanted to recommend that from an ambience standpoint in the area, the use of private drives. We currently share a private drive with the Mancino's that was, has subject to a lot of easements and what not and are finding that the arrangement to be quite ' workable. We want to encourage some of that kind of development because I think it adds to 30 Planning Meeting - August 17, 1994 the area. It promotes somewhat of a lower density which is why we actually chose to move out to this area. And lastly I wanted to speak to the nature of the development in terms of the overall road ' and density and I wanted, to encourage the city to do anything it could to accelerate any traffic work that was going to go on as was mentioned tonight to us earlier about the light a TH 5. Since that, there is quite a bit more traffic that is already coming , into some of the developments on the south. Thank you. Scott: Good, th ank you. Would anyone lelse like to speak? Yes sir. ' Sam Mancino: am Mancino, 6620 Galpin Blvd. To get back to a point we made earlier. We know that d 's ... potential to develop but we would like to revisit this plan for a moment ' because we are oing to... What I'd like to borrow these for a minute if I could. To remind you of the confi ;uration of our property. , The lines okay start immediately south of our property line. And there's a stand of trees along here that straddles either side of the line on that property an: I there's some bluffs here. When we first became aware of the Ryan's intent to develop, we 1 vent out and tried to understand the impact that that was going to have on us and understand t from an access point of view and a utility point of view, from land use ' point of view, and from conservation and things like that One of the things we had to understand first, what was going to go on next to us and what basically was the land use intent and a lot of the first things that we found was the original design pushed Lake Lucy ' Road up to the roperty line. That the intent was to grade basically all the way through the tree line and on this site plan that would put that grading about here where our house is. So that concerned i s to begin with. Just a little concern. Throughout the process of seeing the , plans start to evolve here, what we've seen is a continual kind of a paradon that was drawn originally on a at piece of property but has ultimately translated itself into turning the land into a flat land. They're trying to take all of the ground from here and transpose it over on ' this side by grading all the way up. And I think that what we've heard is just basically to maximize the number of lots, which is not our point to comment on other than it does tell us about the size, to shape and configuration of that and that it no way is that compatible with ' what we see going on up here. That we would like to argue against forcing any penetration at this point because we think we can access our property through here, ultimately migrate out through here ... for a connection at this point. We are concerned on a few other things. As their grading plan started to evolve, even! heir latest version which pushes the road down 60 feet, still has severe grading and as their 'engineer has said, we won't lose too many trees here but as he's also said, if you grade 2 feet you lose trees anyway. So what we would like to request is a 30 of easement, conservation easement along here. The consequence of their grading, any of he remaining trees on their property, which are indicated through this section , and show up on some of these plans, will all go away. They're not preserving a single tree that I'm aware 6f in this section of the property so at minimum we'd like to be able to request that this be a buffer be provided and that we be given an appropriate utility easement ' 31 ' ' Planning Commission Meeting - August 17, 1994 for the lot to the edge of the conservation easement for future access. We also agree with staff that in their current plan, I'm not sure if it will show it on here but what is shown as ' Lot 10 is an unbuildable lot and they're trying to build some very, very steep retaining walls and do some severe grading again on the premise that more lots equals more money and I'm not certain that that's an acceptable premise. It's possible but I'm not sure that I believe that. And that I think as another by product of this 60 foot piece, if you look at the grades here, it's probably very doubtful whether they'll be able to grade out and...encroaching on the ' required conservation land. Charles, is there anything that you'd like to add? Charles Stinson: I'd like to add to if I could. I think a lot of it, Charles Stinson. ' Minnetonka. I think the point being that we're real concerned about anything that happens across there, just as we're, I thought your comments on the last project were just very good as far as taking the time to identify really what's happening here because I think just having ' hiked this site and I think the same thing across there and I'd suggest that maybe if everybody could, it'd be really helpful because I think you can really see how the lay of the land is and what's going on and how both access. How important it is for the access points 1 here without disturbing the change of topography here as well as down here. That if you brought the utility lines, the utilities up here and here to the tree zone, we could have access here. But leaving everything unmolested so to speak, especially the road coming up. One ' thought I had and this isn't I talked to the Mancino's and I'm not having these comments representing them. They're just my own as a citizen but could you put that back up on the screen. Just a thought I had is that I believe there's always a winning solution for everybody, including the land owners and all the neighbors but it always takes a long time to get there. I think Sam had a great quote from Mark Twain that was, if I had more time I would have written a shorter letter, and I think it really applies to development. The longer you think ' about it, you can always find a simpler way of doing it than makes everybody happy. But I think one of the thoughts is, I think one nice thing about having a road at this point was the ' fact that, and I liked the other idea about the road coming up here instead of right here. I guess I'll do one thing at a time. I think the engineer's idea of coming up here I think was a good idea. Cul -de -sac this so you don't have a road here and I was dust wondering if you could do the same thing with that one. Cul -de -sac from here so you don't have anything so close to the intersection there, just as far as safety to that corner and you're just having the streets, two openings here. But the thought over here, the nice thing about having a little, and ' just for the citizens driving by as you're looking across the wetland and you're not doing anything to it and it's kind of a pleasant drive in the midst of a lot of development. The ideal thing for here would be perhaps some private drives or do some as private drives going ' up here. But the other thought is, I just whispered to the Mancino's to see if they'd be interested but you know there's a value that you put on on this piece of property that you're going to get from developing and selling it and if you back out the cost of what it costs for ' the roads and utilities, maybe there's a land value that the Mancino's would just buy from 1 32 Planning Commission Meeting - August 17, 1994 you and then yob wouldn't have to worry about developing it. I know you still have the pheasants running around and the deer and everybody'd be happy but I don't know if there's any, if that's possible to discuss about that but it just seems like there's a lot of development happening in a small area and that's it. Sam Mancino: Dne other thing that I'd 'like to add. Throughout this process I've appreciated the difficulty that staff has gone through in trying to put all these pieces together. They've worked awfully hard at it. They have made an alternative suggestion about C, about exactly a variation on their point which is as much as this area relates to development from that site, given sequencin , yes. This area up here does actually relate more to development but there's a definit 6 sequencing issue. We have had very little time since the report came out to think about how C would work. I know this was a sketch but when I actually put the pen and the ruler on it, we found that our house was actually right here and so we, before we comment on that we'd like to have a little time to understand the engineering implications of that kind of a p an. So we'd like to reserve comment on that at this particular time, if that would be okay. Scott: Good, thank you. Would anybody else like to speak at the public hearing? Okay, seeing none, may I have a motion to close the public hearing please. Ledvina moved, Nutting seconded to close the public hearing. All voted in favor and the motion carried The public hearing was closed. Scott: Matt. Ledvina: Okay, where do I start? Mr. Buresh made some comments as it relates to the zoning and the done change and I think you made some good points as it related to that but the other thing that I, another important factor we look at when dealing with zone changes and looking at the comprehensive plan for how this is developed in the ultimate relates to how is this goir g to fit in with the other ;parcels and as I look at this parcel, the Shamrock Ridge, you look at County Road, or Galpin here and in the future that area, or that road will be a 4 lane roa . So you have that as somewhat of a buffer between the other land use to the east. And then also I think the developer has done a reasonably good job of orienting the ponds, etc to provide some open space beyond that to the west before you actually get into the development area with the lots that are indicated. And even the lots along that side are fairly large size lots in comparison. They're above the average in size. So we understand the residents concerns as they relate to transition with density and I think we're trying to do as good a job as a can as it relates to the ultimate development for this area. So we try to work that into a.-count. Looking at the staff report and walking the area and kind of getting a feel for the relationship of this parcel with the other two parcels. This is, they're definitely 33 I. ' Planning Commission Meeting - August 17, 1994 all together and really you have to look at how it's going to work. I think the staff is re g Y Y g g pretty ' close in terms of their ideas on this. I would choose, or I feel that the Lake Lucy Road alignment as originally proposed by the city along the southern portion of the parcel, is the best alignment. The other mayor point that staff makes relates to the western 1/3 of the ' property. That essentially that arm west of the wetland area there. That appears to be premature in terms of the development of this area at this time and I would support that area being platted as an oudot at this time. I mentioned it with the other plat. I look at this ' extremely steep hill and it's, the views to the south over the wetland are really actually breath taking. It's a very beautiful area. I can, from my perspective, if I could see this whole area being graded flat and I don't know, I just can't see what would be gained by that process. So ' I think the road probably has the least impact on the area in it's proposed alignment. I did have one question for you Bob. As it relates to the tree stand on that western portion. I look at the tree inventory. I think it's, let's see. Something like 621. Is there 648? Somewhere ' in there. There's quite a few reasonably sized trees. Do you know if those trees will be saved with the alignment? The proposed alignment of Lake Lucy Road. The city's alignment. I know, I don't want to put you on the spot but I. Generous: No, I haven't really... ' Ledvina: Right, right. Well whatever. I think the possibilities of those trees being saved increase. I don't know for a fact but I think the possibilities increase there so, and that's something that I'd like to see looked at. I had a question about trails and that recreational ' opportunities. We have a trail proposed along Lake Lucy. Lake Lucy Drive. Is that on the south side or? ' Generous: North side. Ledvina: North side, okay. Are we proposing any trail or easement along the west side of ' the wetland area which you've identified as Outlot A? I know in the past we've done a lot of trails around wetlands and I'm just wondering, this is a pretty large wetland and I don't know ' if there's a good chance or an opportunity to have a trail around there and how that would fit into our trail needs. t Generous: I don't believe the Parks Department has looked at that. That's actually on the Carlson property so that hasn't been proposed with the development. This wetland continues over to the west. ' Ledvina: Right. Well, continues to the south where Outlot A is, yeah. Just a thought. I don't know if you would take a look at how that fits into the overall scheme because I know ' in the parcels further to the south towards TH 5, we've got trails that are along our wetlands 34 Planning Commission Meeting - August 17, 1994 ' there and those a nice amenities and if we could do something like that here, at least get an easement there, that might make some sense. Let's see. I guess I'm not going to look at a ' lot of the details but I would support the' staff recommendation of generally I think they've done a good jot of evaluating this and I think that this thing, this plat would need some work before it could Bally be considered tying, into the overall development of this area. ' Scott: What kir d of direction would you give? Ledvina: Well, I would give I think, just as I mentioned, I would prefer the feasibility study alignment. I w uld prefer that the western 1/3 of the parcel be platted as an outlot. And that area, that very s rep slope area be developed somehow. I know Mr. Mancino mentioned that ' the street goes rght through his house. Obviously we don't want that but maybe there's another alignme it to the west that might'work there. I definitely think that area should be served via acce s from the north. And as I look at it, maybe there's a possibility of serving it ' from the east somehow but by private drive as Mr. Stinson has mentioned. So I think those are the most im ortant things. I generally see a lot of grading that I don't think is necessary but it's not as tical in the eastern portion of the property as it is on the western portion of ' the property so aybe some, a little more sensitivity can be used in the grading processes if this is redeveloped. Scott: Good, Lidd. Conrad: I ask question of Dave. Is it real clear to you that Lake Lucy Road shouldn't be ' shifted to the north? Is there any solution? Hempel: I believe the City Council's already made that determination with the approval of... ' on June 13, 1994. They approved the feasibility study and authorized preparation of construction plans and specifications for Phase 1 which is only up to that intersection of the ' Brenden Pond but the intent is to continue with future phases on the southern realignment. Conrad: It surer seems like that portion on the western part of this plat relates more to the ' Mancino development than to this one. I support the staff recommendations. I think the developer shout , has to work. There's obviously a difference of opinion and I think staff brought up some, a lot of good points. I think they have to be ironed out before it comes ' back. Scott: Good, Ron. I Nutting: I also support staff recommendation. The applicant has attempted to address some of the issues tonight. I need to see staff's response to those items before responding to them. ' 35 t n t Planning Commission Meeting - August 17, 1994 I can't act in a vacuum and so I would support tabling this application and addressing it. It also, when you've got a key issue with just the southerly versus the northerly route of the road and it seems to, it appears from what was said here tonight that the southerly route is somewhat cast in. Aanenson: I don't want to differ with Dave but the Council did, they did leave an option on the Gestach- Paulson piece. That Outlot A that showed a portion over to the south so in deference to what the Ryan's are trying to do. There was some flexibility. We know it has to touch down on a certain point on Galpin Boulevard. There were two proposals shown. A northerly and southerly one in the original, in the original Lake Lucy alignment. A northerly and southerly alignment and they gave feasibility for the supplementary phase, they left the option out whether it goes to the north or to the south so I think their response that they were trying to decide what works best for them and they pushed it to the north. That's what they originally came in with. And we said it just didn't work because they're grading into the Mancino's property... Then we started moving up and down the property trying to figure out where it works best. And going back to what Matt said, you can see the dilemma we were in. Throwing out property lines. You just look at, how should this property best be served. That's what we came up with and that's, the problem is that the property lines don't follow the natural topography and as Mr. Plowman indicated, once you ... 2 feet, what's the difference. Well that's the problem. There are some unique natural features there that we're trying our best to try to maintain. And it's not a flat, square piece of property that you can lot out 15,000 square foot lots. It's got some unique features but they will respond to the option of, there are two options showed in the—study for Lake Lucy. One to the north and one south so that's what they were responding to and I just want to make sure that that was clear. And that's what we were asking your direction to give to them. Do you want to go to the north or to the south and our preference was, to keep it south. That's what...keep it towards the middle. Nutting: The impact if it was to the north on the previous applicant's proposal, just looking back at that. Do you have any drawings? If the road was to the north. Hempel: I'm sorry, which development? Aanenson: The Ryan's? Scott: Gestach? Nutting: No. ' Scott: Gestach- Paulson? 36 Planning Commission Meeting - August 17, 1994 Nutting: Paulso�. Aanenson: Y Generous: You d have lots on the south :side of the Lake Lucy Road and on the north side of Lake Lucy Roa . Aanenson: Streot front facing lots. Nutting: Okay. So you'd have the issue of private drive. Aanenson: Fro t facing lots on a collector street, yeah. Right. Nutting: I guess I would concur with staff's recommendation and Matt's observations as well in terms of the southerly route so I don't; have any other comments. Scott: Okay. Can I have a motion please? Ledvina: I wo Id move that the Planning Commission table Case #94 -7 SUB, is that right? Scott: Yes. Ledvina: Okay The Shamrock Ridge subdivision plan. w to table 94 -3 and then the rezoning and the wetland alteration permit? Scott: Do a eed g Pe Okay, why don 7t you add that. Ledvina: And I would add those under the items as well. Scott: Good. Can I have a second? Conrad: Scott: It's bee moved and seconded that we table the issue. Or all three of them. Is there any discussion. Ledvina move , Conrad seconded that the Planning Commission table action on Subdivision ;1-7, Rezoning #94 -3 and Wetland Alteration Permit #94 -3. All voted in favor and the otion carried. 37 1 Planning Commission Meeting - August 17, 1994 IScott: Oka thank you all for Okay, y o coming. J 38 HARLES W.

Box 147 Chanhassen, MN 55317 Re: SHAMROCK RIDGE PRELIMI ARY PLAT- single family residential Dear Mr. Generous, Enclosed are �opies of the revised preliminary plat drawings for your review. As we have discussed the alignment of Lake Lucy Road at the west end of Shamrock Ridge has not been changed from the northerly locations as shown on the previously submitted preliminary plat. The southerly alignment (option 1 of the feasibility report dated May 25, 1994) does not allow development of the westerly portion of Shamrock Ridge in a practical nanner. To develop cuidesac lots off of Lake Lucy Road with the southerly alignment would result in significant loss of trees along the north property line, require retaining wall construction and provide tuck under type lots of lower value than walkout lots overlooking the treed wetland area. In addition, some wetland fill would occur to construct Lake Lucy Road along the wetland. We feel the northerly alignment (option 2 of the feasibility report), as modified to sixty feet south of the north property line, is the location needed to provide a more feasible lot layout and reduces environmental impacts by preserving trees and avoiding wetland fill. We have made revisions and additions to the attached preliminary plans to address the i ems in your staff report. Please call me with any questions or comments regarding the above. Charles W.

The nent plan should be designed to meet the existing functions and values that have > a result of filling in other wetlands. It is possible to replace the wetlands at a rpland and a ratio of 1:1 as wetland restoration. The City is going to start a the near future by restoring wetlands that have been drained. It may be possible ling points as part of the mitigation for this site. Staff thinks that wetland uld occur in the large wetland to the west rather than creating a small wedand ge stormwater pond. tten to replace wetland values where avoidance of activity is not feasible or ies for avoiding wetland impacts should be considered as part of the wetland process. In addition, to the requirements of the WCA, the CWO requires a buffer strip and buffer strip monumentation around the wetlands. The buffer strip width required for natural wetlands is 10 to 30 feet with a minimum average width of 20 feet and the buffer strip width required for an ag /urban wetland is 0 to 20 feet with a minimum average width of 10 feet. The principal structure setba4 is 40 feet measured from the outside edge of the buffer strip. The proposed grading plan wi, l have to show the buffer strip and the appropriate house setbacks.

The SWMP will to protect, preserve, and; enhance its water resources. The plan identifies the itity and quality improvements from a regional perspective necessary to allow lent to take place and minimize its impact to downstream water bodies. In ;r quantity portion of the plan uses a 100 -year design storm interval for ponding sign storm interval for storm sewer piping. The water quality portion of the plan alker Jr.'s Pondnet model for predicting phosphorus concentrations in shallow n ultimate conditions model has been developed at each drainage area based on land use, and therefore, different sets of improvements under full development determine the optimum phosphorus reduction in priority water bodies. C L Bob Generous ' August 31, 1994 Page 3 ' In conjunction with final platting and the construction plan review process, staff will require the applicant to supply drainage plans providing the pre - developed and post developed drainage areas ' along with runoff calculations for pre - developed and post - developed conditions. Storm water runoff from the site shall maintain the pre - developed conditions for a 100 -year, 24 -hour storm duration. Water quality ponds shall be designed and constructed in accordance with the Walker ' Pondnet model which essentially uses a 2.5 -inch rainfall. In addition, detailed drainage plans and calculations indicating drainage to individual catch basins will also be required. The grading plan shall also reflect the normal and high water elevations in the wetlands and storm water ponds for ' both pre- developed and post - developed conditions. ' Water Quality The SWMP has established a user fee aR aOeSffient Fate for water quality systems. The cash dedication will be equal to the cost of land and pond volume needed for treatment of the phosphorus load leaving the site. The requirement for cash in lieu of land and pond construction shall be based upon a schedule in accordance with the prescribed land use zoning. Values are calculated using the market values of land in the City of Chanhassen plus a value of $2.50 per ' cubic yard for excavation of the pond. If the applicant is- prepeses -te constructs the water quality basins, these fees will be waived and credit given for any oveisizing. ' Water Quantity The SWMP has established a user fee an assessment rate for different land uses based on an average, city -wide rate for the installation of water quantity systems. This cost includes all ' proposed SWMP trunk systems, culverts, and open channels and stormwater ponding areas for temporary runoff storage. Single - family residential developments will have an assessment rate of $1,980 per acre. The proposed development would then be responsible for a water quantity as- ' sessment fee of $63,360 assuming 32 acres of developable land. The City will apply credits to the applicant's surface water quantity fees for construction of improvements in accordance with the SWMP which include such items as outlet control devices, trunk storm sewer pipes, ponding, ' etc. The exact fees will be determined after final review and approval of the construction plans and specifications and Lake Lucy Road assessment methodology if applicable. 1 DRAINAGE The development is located within the Lake Lucy Watershed. The SWMP should be reviewed by the applicant's engineer and the site designed in accordance with the SWAP design to the extent feasibly possible. All runoff shall be pretreated before discharge to any of the existing ' wetlands. Similar to Brenden Pond, Lake Lucy Road will intersect this parcel. The applicant's plans have included a segment of Lake Lucy Road; however, it does not correspond to the City's feasibility study. The Lake Lucy Road alignment is shifted northerly to facilitate two cul -de -sacs on the south side of Lake Lucy Road adjacent to wetlands. A storm water retention pond to pretreat runoff from the cul -de -sacs. and part of Lake Lucy Road is proposed adjacent to the Bob Generous August 31, 19� Page 4 wetland. Anot Ier storm water treatment pond is proposed adjacent to Galpin Boulevard lying both north and south of Lake Lucy Road'!. Staff has mcommended to the applicant's engineer to delete the southerly pond and extend storm sewer to the existing culvert underneath Galpin Boulevard. Th,� pl—ans; p-repose on the in!& and outlet disehafge points of the storm seweF system Depending on - he applicant's timing, they may petition the City, similar to the Brenden Ponds developer, for he construction of Lake Lucy Road through the parcel. This would be a 429 public improvement project whereby the drainage, utility and street improvements would be partially assess d back to the benefitting property owners. This alignment is also a State -Aid route where State-Aid funding may play a role to assist in the funding on the project. Unfortunately, state aid funds have been encumbered for the next three years. Another option would be for the applicant to construct the entire segment of Lake Lucy Road and be given credit for oversizing any utility lines and creditfor the trail system along Lake Lucy Road. According to the City's SN IMP, three storm water pretreatment ponds (Walker ponds) are proposed on the site. One is located just east of Galpin ,Boulevard at the intersection of Lake Lucy Road and The e-t e� tv ;e ere Galpin Boulevard. Another one is located just northerly of the wetland areas. The applicant has proposed constructing 'lire two of the three ponding areas. ' SWMP also proposes a thi water quality basin at ;the end of the ravine in the southwest corner of this development aind extends westerly into B'renden Pond. It may be feasible to consider combining the proposed pond between Gwendolen Court and Mary Bay with the proposed SWMP pond in the southwest comer and Brenden Pond.; 'Ibis area then could be utilized as a mitigation area. The applicant may be given credit for the oversizing of the storm water treatment ponds and any trunk storm sewer facilities they install in conjunction with the overall development. This will be further revie ed upon the final plat and construction plan and specification review process. Staff encourages the applicant's engineer'to review the City's SWMP plan for appropriate sizing of the ponding areas and trunk storm sewers. The storm ponds should be designed with access in mind. A 4:1 side slope is required along /over the storm pipe which discharges into the pond. The pond shout be designed and constructed with a 10:1 bench at the normal water level (NWL) for the first one foot (depth) of water and the remaining at 3:1. Another alternative would be to design the pond with 4 :1 slopes overall. GRADING The site contai . ravine area. TI types of slopes grading.

With these it is very difficult to prepare a site for streets and house pads without significant ias reviewed the plan and has prepared a few options with what we believe would ale approach to developing the steeper part of the site (westerly 1/3). We believe he north (Mancino) was to develop prior to this development we would require I� 1 Bob Generous August 31, 1994 Page S that a street be extended to the northerly line of this plat for a future cul -de -sac to extend lots off of this high ridge. This would make use of the existing topographic features of the property ' without substantially altering the grades. This would also allow for Lake Lucy Road to be extended along the southerly portion of the site to maintain a sufficient buffer and setback below the proposed homes along the northerly portion of the development. It would also allow for ' sufficient wetland mitigation and storm water treatment ponds adjacent to the wetland. One of the drawbacks with regards to this approach would be the lack of benefit that this development would receive from Lake Lucy Road. It is the City's intent to partially assess the benefitting properties for the construction of Lake Lucy Road; however, in this segment where no direct benefit is received the City would have difficulty assessing a portion of Lake Lucy Road. However, the City may does have alternative financing methods such as State Aid to assist in ' developing the roadway system. Unfortunately, these funds are encumbered for the next three years. ' The grading plan as proposed with the Lake Lucy roadway alignment to the north has very steep backslopes (2.5:1) adjacent to the ^ r-b .,.high are of areeptable. The City's typical street section ' requires a boulevard area and then 3:1 slopes. In addition, this alignment will not match with the development to the west (Brenden Pond). Staff has been woiiang with the applicant's engineer in realigning Lake Lucy Road to match to the west and provide appropriate boulevards and backslopes. This appears achievable by slightly curving Lake Lucy Road southwesterly and shifting the street south by approximately 20 feet The southerly alignment of Lake Lucy Road is still preferred by staff. The ^ plie . ; „ 34 slepe .immediately L.,,hind the ^ ._r. ' Thi ' •vill ~^* allow for- The proposed 8 -foot wide bike trail along the north side of the road may be realigned to assist in improving the side slopes as well. The use of retaining walls may also be employed to lessen the grading impacts; however, if this is done as a part of the City project ' it will increase costs significantly for the construction of these retaining walls and limit future street widening if so desired. The applicant is also proposing three lots to access off of Lake Lucy Road immediately across from Mary Bay Court. Staff believes that Lot 14 4-9 is an unbuildable lot due to the steepness of the grades and proximity of Lake Lucy Road. Lots 12 & and 13 9 may be serviced off a private driveway off of James Court which would modify the house design from a tuck -under which is not desirable to a walkout which is more valuable. Staff is also recommending extending a street stub north towards the Mancino's from James Court The street could terminate at a point short of the tree line which would provide access to the last lot (9) and future extension to Mancino's if desired. The applicant is proposing water quality ponds adjacent to Galpin Boulevard. Galpin Boulevard is classified as a local collector street and will need additional right -of -way dedicated with this ' plat. According to Carver County, a minimum corridor of 100 feet should be reserved for future upgrading to a four -lane street. T4erefer- , it i - The applicant is to dedicating an additional 17 feet of right -of -way along Galpin Boulevard to fulfill the County's requirement. ha _Additien, the first inteFseetien west ef Galpin Boulevard is too elose fr-ein a spaeing standpoint_.

EROSION CONTROL ' The applicant will need to develop a sediment and erosion control plan in accordance with the City's Best Management Practice Handbook (BMPH). Type III erosion control fencing will be required around all the nm wetlands being preserved. The steep slopes may also require some ' form of terraced erosion control fencing. The plan shall be submitted to the City for review and formal approval. The City has adopted a Best Management Practice Handbook which the ' applicant can purchase from the City at a cost of $25 to assist with the design process. STREETS ' Access to the development is proposed from Galpin Boulevard (County Road 117). Another access will also be extended from the west if the City continues with the extension of Lake Lucy ' Road. Lake Lucy Road may be built under the City's improvement project program if so petitioned by the applicant and authorized by the City Council. Lake Lucy Road is considered a collector street based on the City's Comprehensive Guide Use Plan. It is also part of the City's ' Municipal State -Aid Route. According to the City's subdivision ordinance, direct driveway access onto a collector street should be restricted or controlled whenever feasible. Staff believes that Lot 14 4-9, Block 2 located north of Lake Lucy Road, is not a buildable lot; however, Lots 12 9 and 13 -3, Block 2 should have a driveway access from James Court which would eliminate any driveway access onto Lake Lucy Road. Staff believes this is a feasible alternative to having direct access on to Lake Lucy Road and should be required as a Condition of Approval. The alignment of Lake Lucy Road west of this development has not been finalized. The City has prepared a feasibility study for the extension of Lake Lucy Road from Trunk Highway 41 to Galpin Boulevard. There are two other parcels of land that are directly impacted by the future alignment of Lake Lucy Road. The first parcel is located just west of this development and proceeding ahead with a preliminary plat (Gestach parcel - Brenden Ponds). The other parcel (Mancino) is located to the north of this development. Staff has reviewed with the property owners several options for access to the Mancino parcel from the Brenden Pond development and ' this development. Brenden Pond will be providing the Mancino parcel access to the westerly portion via private driveway. Staff has also met with the Ryans to discuss two potential alignments for Lake Lucy Road which impact this development. There is no clear -cut alignment of Lake Lucy Road that satisfies all of the property owners in this situation. The preliminary plat of Shamrock Ridge has utilized a northerly alignment of Lake Lucy Road through their parcel. Staff has reviewed this preliminary plat and finds numerous problems from a design standpoint which will have to be resolved, which may or may not thus potentially reduce the number of lots. The applicant's engineer will be supplying staff with a revised plat that addresses most of these Bob Generous August 31, 1994 Page 8 problems. Staf has also reviewed the southerly alignment of Lake Lucy Road through this parcel which leaves the westerly portion of the; very difficult to develop due to very steep slopes. However, this alignment works well with the existing terrain and minimizes impacts to the wetlands. The esulting impact from thei'southerly alignment of Lake Lucy Road requires short, steep cul -de -sa s as well as tuck -under type homes to the north of Lake Lucy Road unless access is from the no (Mancinos). Staff hits put together- thFee options that we see feasible fe-F . still believes that the ent is the preferred alignment for Lake Lucy Road. The proposed plan at this southerly align time still nee some minor alignment changes in order to achieve 3:1 backslopes along Lake Lucy Road and match the touchdown port on Brenden Pond (Gestach Paulson). The applicant's engineer and C i ty staff believe this can be accomplished if the northerly alignment is acceptable to the Planning Commission and City Council. The applicant is proposing to dedicate an 80 -foot wide right -of -way for the construction of Lake Lucy Road thrc ugh the development. The plans also propose a 60 -foot wide right -of -way on all the streets except for Mary Bay and Gwendolen Court; and construction of the City's standard roadway sectio: i for the interior streets. The right-of-way for Gwendolen Court and Mary Bay shall be widene� to 60 feet vs. 50 feet unless the applicant can demonstrate some benefits to the City. Street grades range from 0.5% to 7 % which is the City's maximum grade allowed. Detailed construction plans and specifications for the street improvements will be required as part of the final plat submittal. Show Access to the Mancino parcel shall be provided by extending Jennifer Way to the north side -ed through the n^4" end of James Court through Lot 9, Block Z, and conditions stipulated in the developme �t contract that this street may be extended in the future.

Ledvina: Bob, what led you to change your opinion as it related to the Lake Lucy alignment? What now makes this an acceptable proposal in terms of the alignment? ' Generous: It's the best we can get. Since they're not willing to go along with, the preferred development pattern would be to outlot that property but you cannot force them to do that ' provided they provide us with a feasible alternative. This way they at least leave in some of the topography whereas if they go in and have the southern alignment, they're going to ... so they can put their housing pads in and then we'll either have large retaining walls on that side or a steep slope there. J LI Aanenson: If I could just expand upon that. The intent was always to preserve the natural topography as much as possible and our first choice would be to ... property to the north. ...so this way we felt, at least we're getting preservation of that area by swinging the road to the south. Whatever you need to maintain the 3:1 slopes, that would give you the preservation area along the northern boundary ... So if they would be willing to wait until that did change, that would be the best way to do that but we can't force the issue. Generous: And we couldn't persuade them. Ledvina: Okay, thank you. Scott: I'm just taking a look at some of the preliminary grading plan and my big concern is we just had sent on a bluff protection ordinance and from visiting the site and from viewing this, it appears to me that there are some steep grades that fall within our bluff ordinance here and that's, I didn't go out and measure them but I'm going to need somebody to tell me that they have been measured and they don't, the bluff ordinance does not apply to the northerly section of this property. Generous: I did a cursory review. I did not measure all of it and at least the places where I ... it didn't meet the ... It has the elevation change but not the slopes. Scott: Okay. Questions? Comments? Would the applicant or their representative wish to make some comments? If yes, please identify yourself and give us your name and your address. Ed Ryan: My name is Ed Ryan and I'm the owner - developer of the property. And my wife Mary. I'm sorry I missed the last meeting. I had an accident on my property which I'm recovering from now and that's why I missed the last meeting so I apologize for that. Mary Oa Planning Co i, ssion Meeting - September 7, 1994 LJ and I have taker great care in developing our property. I mean we've been in Chanhassen for many years. W appreciate our property ivery much. And in working with staff and suggestions from our neighbors, during this whole process we've been focusing on a number of issues when we put our plans together; which have been revised many times. Tree preservation has always been a concern of our's, especially up along the north line. We have, , from the original proposal that we had a few weeks ago, we have dropped the road significant to the south to accommodate those grades and the sloping of the road. We've also in our proposal have tried to preserve the wetlands to the south. That whole wetland in there is a , natural wetland and by having the road to the north we don't do any disturbing of that roadway during the building process or the grading process so we felt that was important. We have large lot sizes and we tried to preserve the rolling topography of our property. It's ' a beautiful piece. Mr. Chair, I think you've seen it. It's very pretty, rolling type farm acreage. It has significant trees to the north and it has trees, significant concentration of trees in front of our property which we have preserved. We've also tried to take into account how Lake Lucy current is. This is going to be an extension of Lake Lucy and if you drive Lake Lucy from Pow rs to Galpin, you'll notice how that road curves and winds sort of gently and it rolls with the opography. It's not flat.'... It's not straight. That kind of roadway would be I think a disturbar ce to the neighborhood so I think this plan accommodates that. As the staff has outlined, they ould recommend approval of our plat, which would include the northern alignment if we would agree to all their recommendations. Chuck, our engineer, will be ' addressing some of those issues after I speak and we have met those or in the process of meeting all of those conditions. Still though we find that there is I think some general confusion regarding this whole city original feasibility study. And I think through the process , that we've gone through, we feel that the! original feasibility study that was addressed, it takes on a different light. ht. The study was prepared by Bill Engelhardt, as you know, and he's an independent consultant. An engineer that was asked to design a roadway from TH 41 to the touchdown spot where Lake Lucy is now. That's what he was asked to do. Now Bill was not charged wi developing a developable plan for the western property or for our property. He wasn't asket ' to do that. He was asked to find a way to connect these two. And he did so, and he did a fine job. However, as the western plat developed, this alignment changed and the reason i changed is because ownership changed with that western section. And so , the road had to be configured. Had to be changed. There were some modifications there. The original fear ibility study was reviewed by the City Council on June 13th. And at that meeting the sole southern alignment proposed for the property was changed to include the , northern alignment. This was called the 'supplemental feasibility study. That's what was approved by the City Council. At the Council meeting the city approved the study. Not the original feasibility study which showed al northern route and a southern route. And it , outlotted the eastern section of the western development so that, in their words, this will give maximum flexibility to the Ryans when their property would come to be platted. This is the history of that f asibility study. I'm sure. Bill did a fine job but he did not have a , Planning Commission Meeting - September -7, 1994 development in mind. He couldn't have. And we have. And with that development we've ' taken input from staff and our neighbors and other input to try to accommodate and make it a pleaseable plat and a nice development. Chuck, our engineer will share with you why the northern alignment is preferred. We feel it's preferred. And let me turn the podium over to ' him. Scott: Okay, thank you. ' Chuck Plowe: Mr. Chair, fellow members of the Commission, my name is Chuck Plowe and I'm the project engineer for Shamrock here representing Mr. and Mrs. Ryan. Do you want this just out front? Scott: I think you put that right in front of the podium or over to the side. Chuck Plowe: Allow me to hand out something that I J otted down in writing in regards to the reasons for the alignment that we prefer. Anyone else that wants copies, you're welcome to grab one. I think most of this has been covered in some fashion or another in this report but let me Just reiterate a little bit, and basically I've put down something in writing that I believe I've stated ... That southerly alignment we feel is not the appropriate location for the following reasons... Filling of the wetland will occur. The trees along the north, on the north property line will not be preserved. The final lot configuration, as you see these red lines on this particular plan here, which show Lake Lucy Road to the south, is less pleasing for the residential development within the community of Chanhassen. The residents would not enjoy the view of their backyards abutting the ... wetlands, and I think that's important. For the ' community I think it's important. The proposed northerly alignment of Lake Lucy Road, which is underlined here, will preserve the trees along the north and also will not impact the wetland in any way. And we've met all the staff conditions for their approval of the ' northerly route with the exception of a couple things Bob has mentioned that we need to look at a couple items as he has indicated tonight. But let me further go into this item with Lake Lucy Road to the south. I've drawn a line, you can see here. I call it Section DD. What I've done is along that line I'm showing on another drawing the existing ground line and the ' final ground line after development with the elevation of Lake Lucy Road being approximately like what staff had indicated in their report that it would be if it were along the southerly route. Existing ground line is the blue line. And proposed ground line is the, I call it the orange line. The bottom of the hill, being wetland area down here. Top of the hill being the treed area up here. Generally what happens here is we do encroach into the wetland with the roadway. But to construct a roadway with Lake Lucy Road being there, there's definitely going to be some fill into the wetland. In fact I shorten the boulevard up to 10 feet and there's still fill into the wetland. With 3:1 slope, which is... At the other end where we come up the hill with the lots, I've tried to show you, again to kind of give you a Planning physical feel f be about here of the house p into the trees haven't really So this is, I'm about it, how 1 Meeting - September 7, 1994 where things are. This is the center of the cul -de -sac street. The curb would 3 then the right -of -way, !front yard lot line and then the approximate location , And then the back yard with the 3:1 slope. As you can see, it extends up I it probably would be much worse than what I've even shown because I ien that ... back yards at all. It just immediately starts going up to the trees. ying to demonstrate to you in a more physical view, other than us just talking 3 fits. Scott: Can I ask you a question? On the, you see where the tree line is. And the existing, it appears to me t> at you're planning on grading into the trees on the north side of the property. Is that, or am I eading that incorrectly? Chuck Plowe: Scott: Yeah. Chuck Plowe: 'What would be correct. In order to avoid that we would have to raise this street up, fill ink) the wetland further. Some things would have to give someplace. Because we're using our maximum slopes at both; ends. This is going to probably require retaining walls to even do this. So I'm looking ati,a combination of retaining walls and going into the trees with the ading because we're probably going across the property lines into the property, although I haven't shown the property line on here. It's approximately right there. I guess that's about it. This is the tree line that I'm trying to show you there. The property line's not going to ... and it continues to rise. Any more questions on this? Scott: No. Chuck Plowe: ' just before the ] better with the 1 curved a little n flexibility to do together but we where we can d through the cul- lines and propo able to extend z actually from tk pretty nice lot a don't impact thi ['his is the northerly alignment which is the plan that I changed or resubmitted tst week. And we did do some curvature of the street to try and align it ature road that would connect it down here. As Bob indicated, it needs to be .ore than what we've shown it and I've discussed it with Dave. There is that. We didn't do a detailed study of exactly how everything hooked did start curving it where before it was straight. This lot is large enough this. When I compare it to the one we just looked at, I've drawn a line Ie -sac again. Generally falling the same location. Showing existing ground ed. Again the wetland is at the bottom of the hill. Trees up here. We are cul -de -sac here. Lake Lucy Road up on the hill. We are able to maintain curb ... to where we begin our 3:1 slope, we're 110 feet so we do have a id we do not encroach into the wetland with the bottom of the slope. We wetland with any fill. And again on this end we're not encroaching into the R IPlanning Commission Meeting - September 7, 1994 trees as well. Now as Bob indicated, there was a problem with this that didn't quite fit. As I understand you were saying there was still some problems here. Can I ask what those are? I guess what maybe you're getting at was that the boulevard wasn't the full 20 feet or 21 feet here. Okay. And that's true. I have about a 12 foot boulevard which allows ... a trail if it ' has to be on that side. But this street will meet State Aid standards. I did discuss with Dave the possibility of having the trail on the other side and that was a possibility and I think it would, appropriate decisions do that because when we're dealing with this kind of terrain and this kind of design, why not put it where there's less resistance. Why not go with the flow but in trying to put it up here would certainly be more difficult than putting it on the other side. I guess the point I'm trying to make is that when we compared the two, the north to the south, this is the environmentally favorable plan. I guess I can say it all I want but I was hoping I could show you. I don't know whether there's any real need to go into the items that Bob mentioned but we do have two pipes discharging into this pond here as we indicated ' and staff, we can combine those into one discharge pipe. That's not a problem. A 4:1 slope getting from the cul -de -sac down to the access there, would simply be a matter of adjusting a couple ... here so there's plenty of lining up from top to bottom to achieve a 4:1 slope and that's not a problem either. We've had, as you can see, gone along with a private drive in lieu of the lots fronting on Lake Lucy Road. We feel that ...and the lots are not going to be impacted doing it that way. As a matter of fact, Lot 14 is better than it was before as far as the grading's concerned. We eliminated some retaining walls which were difficult to fit a pad on that lot...because it was a driveway coming off of Lake Lucy Road in the back yard ... and difficult to work with. We've now eliminated the retaining wall so it's much better in that respect so Lot 14 actually became a more viable lot. That was my comments unless someone else had a question. ' Ledvina: I have a question Mr. Chair. Under staff recommendations related to eliminating driveways onto Lake Lucy Road. I guess how were we going to do that for Lots 4, 5 and 6 1 that you relabeled on, what block is that? Oh, just that area that you were talking about. Where does the private drive come from? Chuck Plowe: We are now extending, rather than having a cul -de -sac in here, we've been asked to extend the street for the future extension to the north. So we've done that and that actually made it a little easier for us to do what staff is asking us to look at. And so what we are proposing is to weave the driveway through the 130 feet of lots. Whatever that is. Ledvina: Oh, that didn't show up very well on my plan. Chuck Plowe: It is hard to see. 2 Planning Co 'ssion Meeting - September 7 1994 � P II Ledvina: Yes. ' Chuck Plowe: That, in most cases, is not fixed by Y an means. It would be ... minimum amount of trees ..That's what would happen there. This is only a concept. , Ledvina: But at represents about the only alternative for accessing those 3 lots then, is that right? Chuck Plowe: In lieu of going onto Lake Lucy Road. That was felt that that was a better option... , Scott: Good. y other questions or comments? Excuse me sir, are you a member of the applicant team? , Frank Kelly: Yes. Good evening. My name is Frank Kelly. I'm the attorney for the developer. Firs of all I wish to thank the members of your planning staff for working with us in trying to and solutions for the problems with this development. This is very complex and there's many problems connected with it and we appreciate the efforts that they have given us. We feel that we are ready to accept, and will accept all the suggestions and recommendatior s as set out by the Planning Department as shown on page 4 as well as the additional ones at were called to our attention, at our last meeting. And by accepting those recommendatior s, the planner indicates that... conditions would make the applicant's proposal acceptable. No we're not asking for any variances or changes or special privileges in platting the property ... of the city ordinance and in so doing, the plat, as far as the planner is concerned, wou d be acceptable to the plat. And if there are any required changes which the Planning Depar ent deems necessary during the course of development of the plat, we certainly will working with them ... to meet those and will meet those, whatever... However, we do ask that you consider this plat and make your recommendation on the plat to the Council favorably. There's nothing more that we can do than meet the requirements as recommended by the Planning Department, and we have done that. We only ask that you approve it subje�a to those recommendations. Without any reservation whatsoever. Thank you very much. Scott: Thank you. Would anyone else like to speak on behalf of the applicant? This is a public hearing. Can I have a motion to open the public hearing please? Ledvina move Conrad seconded to open the public hearing. All voted in favor and the motion carried, I, The public hearing was opened. 1 Planning Commission Meeting - September 7, 1994 I Scott: Can I see a show of hands for people who have come to speak at this particular public ' hearing? Okay, great. Step up.1dentify yourself. Name and address and we'd like to hear your comments. ' Sam Mancino: Sam Mancino, 6620 Galpin Blvd. We are the neighbors immediately to the north. I'd like to make a couple of comments—whichever way the plan is finally recommended. The first point has to do with the fact that with the grading here there are only a very few number of trees being preserved the way it's presently situation. There is a recommendation for a 30 foot tree preservation easement along the north property line. I want to just clarify that that is to be a 30 foot from the northern property line extending south for the full width, east to west, on that property line. The request that we would have is that any private drive that is intended to service the other lots, does not encroach on that...whether that is ... right -of -way for that private drive. Second point I'd like to raise is that we've been advised by a consulting engineer that a utility hook -up will be necessary to service our property if we ever choose to develop it, which we don't at this particular time. The easterly portion that will be shown as a right -of -way and utility hook -up will serve the eastern portion of our property as well but our western edge there is a requirement for another utility hook -up to avoid trenching the center of the ravine that goes through our property. We're told there are other ways to be able to do that but we haven't had a formal ... survey but we're requesting that. Perhaps Dave, you could help clarify whether that would be feasible. Hempel: The plan before you this evening show a street and utility extension over the eastern portion of the Mancino parcel with the extension of Jennifer Way. The Mancino parcel does have a high point at right about Lot 6 there's a high mound. Then it starts to gradually break off there... westerly boundary of the development. The existing ravine takes storm water drainage across the north, right to the west of this development. Actually... development and that area there is the low point of the neighborhood. And we 1 envision seeing extension of storm sewer along the ravine area and possibly sanitary sewer to service the adjacent parcel to the north. The Mancino parcel also will be serviced from the future sewer and water line provided in the subdivision before you here tonight called Brendon Ponds, which is the westerly portion of this site. We're providing at this time 2 out of the 3, what we believe are utility service connection points. Ledvina: Dave, with this development then, are we providing that western utility stub? don't see it here. Hempel: No we are not. We're providing an easterly connection. At this point we believe the appropriate time and place would be with the future development of the outlot that you'll see on the next subdivision called Brendon Ponds. At that time that parcel develops, that would be extended northerly. 8 Planning Commission Meetin g - September 7, 1994 P Ledvina: So w en that develops, that should provide adequate utility service that's needed here for this pa. 'on of the Mancino property? ' Hempel: That's correct. , Sam Mancino: The issue again we're not engineers but whether you trench through the middle of a wet.and ...or whether you take it off of another area that wouldn't violate that ravine quite so badly ... The third technical point that we'd like to question is that the future potential for road connection, which Will also serve to be our utility hook -up, which I believe comes in through Jennifer Way, will terminate at the edge of their private drive and will not be paved completely up to the edge...is that correct at this point? Hempel: That' our intent as long as we extend the street service from the edge of that 30 foot easement at this point and leave the option open. Whether to extend that street in the future ... or connect a street to service that..lot and private driveway. Provide both options. Sam Mancino: couple of other points., One, moving the road 60 feet south from where it ' was originally h itended. 60 feet from the 30 foot tree easement. We understand but don't believe it will h ld 3:1 slopes and be able to do what was originally intended, which is to provide the roac bed, the right -of -way and a trail system. And I guess the question of the trail system is at as this area develops, more kids are there. Their natural route would be to the north to the school and to put that roadway to the south would probably require to cross a major collector road. So that's a point that we would like to have considered because it bears on the grading end the setbacks... There was a request by staff for some planting of sumac and seeding of the graded property. I guess in addition to that we would request, because I'm not , sure how effective this seeding would be, or how quickly that will take root. The sumac will be a very good idea but we'd like to request some spruce and other conifers near the top of the slope to hold the soil. Also to be able to, there's a sound and visual buffer ... Those are really the techni al points I think that we'd like to mention at this time. I think there are some broader questions that we have. The thing that seems to be driving this development is the density. Thi -. need to get as many lots as possible and more density seems to get more grading and we don't believe that, the intent of the comprehensive plan probably took into account average situations. Didn't particularly take into account this topographical situation. I don't believe that this has the creativity applied to it to develop it to the sensitivity of the rest of the land. Another global, broader.- point is that we'd like to see Planning Commission recommend to Oty Council, in light of the development that we're going to see in this area, particularly wi this development, with the Gestach - Paulson, a noise and construction activity limitation that 1' mits it to weekdays so that there would be no noise generated weekends. That could eitht r the form of an ordinance or as a development contract because that would be good for all f the neighbors. I think that I'd like to invite our architect to help us do 9 � Planning Commission Meetin g - September 7, 1994 P I some thinking about this. Charles Stinson to address some of the things that we've seen at ' this presentation by their engineer. Charles Stinson: Hello. My name is Charles Stinson. I'm the architect working with the Mancino's. I specialize in custom homes on unique property and I get involved with some land planning on certain properties that, in which we're trying to save the trees and respond to the topography. I wonder if I could use the, your demonstration board for a minute. Just to clarify. I think Sam commented, covered everything about technically pretty well as far as the trying to keep the 30 foot preservation zone from the top and in doing so, and whatever we have on private drives here skate off of that zone because right now as private drives, if they went over it would wipe out all the trees in that area, which would mean that this property would have to come down this last lot. I guess Lot 1. I guess the other thing, just trying to clarify, and this is aside from that project. This being a guy that tries to save the natural topography whenever I can. Just to clarify the study that was shown as the bad alternative here I think the, what the city was actually recommending or the staff was that I ' think the southerly drive came up just a little bit higher so it wouldn't be quite as steep as this. And I think in showing this process here, I think if the road was a little bit over here, as they proposed, the grading wouldn't be quite so steep going down to the wetlands. There would be some fill here but I think this whole cut is just based on if there's a cul -de -sac going up there. If you're trying to put a road out there, then you're digging out the whole site but I think there's perhaps a whole nother option there that if we could save all that, save that and do some filling where the roadwork is here, then I'm just curious if the owners, developers and the engineer considered the fact that the possibility, if a road went on the southern area and you left all the wetlands the way we have and then at that point we perhaps this cul -de -sac came over this way to service the homes around here and then the private drives just went to the remainder of the out parcel and then leaving the natural topography and the views without getting into anything, was that one of the studies? "Ge,-ktttlr Ed-R-ym( ?): Not that I'm aware of. Chuck Plowe: Let me, I couldn't see exactly what you were just. Charles Stinson: Okay. Well, and maybe I'll go to the, some of the concern, on the plan that's proposed right now, there is a cut here which is substantial and pretty substantial going up to the trees. Does this show your property line or is this the property line? Chuck Plowe: This is the property line here. Charles Stinson: Okay. So you're saving the first 30 feet and then dropping down from there? 10 Planning Chuck Plowe: i'es. Meeting - September 7, 1994 Charles Stinson So there's a cut there but at the bottom of the property, the way it's proposed, or that road area. Not the entire property but this area we're concerned with. The fill that we're talking about is perhaps 8 .feet higher than the ceiling. About 20 feet of fill that would occur here? Chuck Plowe: �t the maximum point, that'd be in the very front of the house near the wetland ... 1l fee which is about where the road grade is when you... Charles Stinson So here would be cutting about 12 feet. Here you'd be putting back about 20 feet... I gues the thought I had was, and I'm not speaking for the Mancino's but I'm just on my own here. Thinking about the environment. If the road went to the south, kind of curving up here a little bit so there's enough grade for that wetland, would it be possible to take this cul-de-sac. Leave everything the way you have it here. There's maybe 10 feet of fill at this point but just taking this cul -de -sac over, feeding the lots here, here, here and here and then just have a private drive go in to more homes over here. Wouldn't that give you pretty close to your density or if this perhaps makes a few more valuable because they such views? Chuck Plowe: Well I think we avoid private drives as much as possible ... and that's a totally different concept than what we're looking at. If we did go along with private drives and eliminate the frontage on Lake Lucy Road, and we did look at several options too. As a matter of fact, v ve went through them with staff. We showed how they wouldn't work. Taking the roadl up into here and leaving Lake Lucy Road down there and that ended up getting a lot of drainage and also some lots with streets on both sides of them so that just didn't work outl Charles Stinson# Okay that, again I guess most of the developments I get I end up doing private drives, or a fair amount of private drives. The reason we do it, and many communities are getting more receptive to it, it's a way of saving more of the topography. More of the nataral grades etc. And that's again, just to go over that again, keeping it low, there would be ery little grading going down to the wetland. This would all be saved and the cul -de -sac c ming here and private d=ives. Perhaps this is a different concept of private drives and I'm i iot sure how you feel about it. We've done it quite successfully and if anybody's interested, I guess ... there's one on Oakland Road in Minnetonka that I did with Streeter and As ociates and it has worked out quite well. And that's it. Thank you. Scott: Good, you. Would anyone;' else like to speak at the public hearing? 11 i r. u u rl Planning Commission Meeting - September 7, 1994 Eric Rivkin: Hi. My name is Eric Rivkin, 6095 Steller Court. I'm about, I don't know, 1,000 yards east of the property and I look out onto it into the sunset. Beautiful sunset. It sets over the hills that they want to take down 80 feet or whatever. And I also am not opposed to the development but I think that it could, the Ryans could have maybe hired this wonderful architect here as an adjunct to their team, this planning team because I don't think it has enough regard for the natural landfonms and I'm opposed to the massive earth moving. I like you to favor the alignment for the road to the south. I think it should, I agree with them completely that the road could meander up a little ways so it isn't so straight but I don't think the plan has got, I don't think the plan's compatible with the surrounding developments. Lake Lucy Commons and these other large estates which have gone to great lengths in the community to maintain natural landforms and preserve forested areas, open spaces and wetlands. I think this is a butchering of the land, just plain and simple and I think much more sensitivity needs to be applied here. If they have to go back to the drawing board, I think maybe they should employ on their team an environmental designer because we have city codes that in my opinion, and I think maybe your opinion, would require them to meet these philosophies and I was one of the people that helped develop the comprehensive plan 5 years ago to try and get laws that would preserve, prevent this kind of thing from happening. The area between TH 41 and Galpin is a recognized natural resource corridor for wildlife who regularly travel in all seasons of the year between two great naturally preserved areas. Lake Minnewashta Park and the Lake Lucy area. And we all enjoy that in this northern part of Chanhassen and we want to see that preserved. I represent, as a Co -Chair of the Lake Lucy Homeowners Association and we enjoy wildlife. We have osprey. We have bald eagles. We have great blue herons. All kinds of wildlife. Fox and even an occasional, the DNR said a cougar. But anyway there's no natural corridor between these planned in this development and it will be too greatly disturbed and devastating. I don't think any authorization should be given to this development that destroys the natural features of land, be it corridor, wetlands, wildlife habitat or vegetation lowland form. I think the developer should be required to propose and concept to a plan which meets the city codes and protection of environmental features and relates to the site's natural resources. And above all gets respect as to the existing development pattern set in the community. I favor those ... lot sizes. I think that their, the access alternative from the north or this long private drive, I think it's a good alternative to consider to preserve that hillside, the top. I don't think it needs to be destroyed... I was at the top of that hill last night. I walked the site with the Mancino's and I don't think that there is any economical hardship in doing that. I would result in a lot less grading problems and if you look at Fox Hollow, there's plenty of examples of tuck under houses on top of hills that sell for a half a million dollars that have spectacular views of the Lotus Lake area. Here you can see 2 miles from the top of that hill. It's one of the highest points in Chanhassen... and it's absolutely magnificent and I don't think they'll have any problem with maybe even cutting down the lot density up there just to Lpreserve that and get their money of the property. The trail system. I paid $660.00 for a trail 1 12 Planning system which I trail, a real trail. natural area like will walk in pea more an amenity they do that app the Lake Lucy F connect with the with Lake Minn areas which woi the natural corri would satisfy th, for years ... at thi what kind of tre should have a re don't mean Dou and... conditions. rows and rows c corridors so the; to the tree cove drainage intends the road.

Anderson Lakes and in Jonathan where people ;e and harmony with nature. Enjoy the wildlife and everything. It's much to the community and will increase the lot values I think considerably if •oach rather than just blow it off as an afterthought. I think that by aligning .oad to winding around the southern portion gives it more opportunity to property to the west. Also for this corridor to, the trail system connect up ;washta would be perfect. So you could have spots to enjoy the wildlife ld be given to the public as conservation easements and sell this thing with tors and sell this thing with the trail system that people want and I think it community and needs and wants and desires for this that we've been having podium many times complaining about. Let's see. Trees. I don't know planting program they have but I think it's pretty clear in the code that we storation that should have native species only that is native to this area. I glas fir or Colorado spruce and things that are not suitable for the soil If there are, and I don't mean like army landscaping where you've got just ,f sumac but take the groves of trees and replant them and restore these ,'re intact and that the disturbance is at a minimum, both to the wetlands and . One question that I have for the developer, and the engineer. Is there any d to go east of Lake Lucy Road from there? Either under the road or over -use me, Galpin. es, to the Lake Lucy watershed... Eric Rivkin: Is there the surface area of water area, is there estimates of how much surface water there is ... to the Lake Lucy watershed? Is it existing? Plans for existing or go beyond that. Hempel: Mr. ( is in the proces wide comprehe comprehensive year that we're quality basins t County Road 1 water will incrt underneath Gal down to Lake ] iairman, maybe I can address that. The applicant's original design—the city of adopting the Surface Water Management Program which will provide city sive storm drainage which has water quality ... to preserve wetland areas as a plan. We're trying to implement that plan with this ponding. This is the first mplementing this program and this development is providing storm water treat storm water runoff and will better discharge the water underneath 7 to Galpin Blvd to drain towards Lake Lucy basin area. The volume of tse the velocity of water but will not restrict the impact to the culvert in Blvd. Potentially there will be a trunk storm sewer system from Galpin ucy with the remaining part... 13 1 71, 1� t Planning Commission Meeting - September 7, 1994 Eric Rivkin: Okay. I'd like to propose, I have a map that shows the watershed to Lake Lucy, okay. Can I put that up? . Scott: Sure, go ahead. ' Eric Rivkin: ...I want to show the engineer first. This shows the Lake Lucy watershed area. This is Galpin Road right here, CR 117. This is all the... Aanenson: I really think the questions are best directed to our engineer. Eric Rivkin: Okay, this is Lake Harrison. There's Galpin Blvd here. You could pass this map around while I'm talking. The point I'm trying to make here is that, the western part of Lake Lucy Highlands development runs into wetlands which are on my property and Prince's property and Class A wetlands and they're very sensitive. They've got rare plants in there. There's already a sedimentation problem now where the culvert is overflowing with sediments from the existing driveways and streets, whatever, sand you know from salting and stuff, and I want, as a representative of the Lake Lucy Homeowners Association, we would like to have a condition that prevents any additional water runoff from this development into the Lake Lucy watershed. You have plenty of mitigation area planned for this development and I think every bit of this water is going to carry pollutants from fertilizers from lawns and the nutrient runoff from development which is going to pollute the wetlands like you wouldn't believe. It's already over loaded. The culvert every spring, which is always full and has not been cleaned out by the city as it should have been and ... storm water management program and the conditions of the development, the Steller Court development which was passed in 1986. There's not supposed to be an increase more than 2 tons of sediment coming out of that culvert and I'm going to make sure that that is upheld. I don't think that engineering wise it's going to work by having any additional runoff, other than what is naturally occurring right now. And what is going off right now, even though there's fertilizers from the farms that are farming now, it is filtered by dirt and plants and vegetative material. If you're adding street runoff and we all know that that stuff is highly polluting and I do not want to see any more water coming from this development into the Lake Lucy Watershed. We've already got enough stress as it is. The Walker Ponds over at Willow Ridge do not work because you do not have natural vegetative areas surrounding the wetlands. The storm water just ran through the holding pond and then overflowed right into that big pond by Lake Lucy Road. And then into the Lake Lucy through an outlet through a massive 10 acre wetland and still caused algae growth. That's how much pollution there was from the development and it's still going on today. So I think it needs to be taken from a preventive stance and I recommend that no water or all the water in that development stay there and be dealt with and conclusively. Another thing about the wetlands, the material.-man made wetlands must be sure to make up for the ones that you're replacing. I noticed the mitigation areas with this 1 14 Planning Conuy#ssion Meeting - September 7, 1994 plan. Is that correct? Okay. I think whatever standards there are to help make sure that they are completely natural in development of ,...thank you. Scott: Thank you. u. Would anyone else like to speak at the public hearing? Yes sir. , Jerome Carlson: M name is Jerome Carlson. I live at 6950 Gal in Blvd or Road, Je y P depending upon which post office you talk to. In following the proposal to date, I'm struck over and over a ain by the feeling that there is nature and the development are not in sync. As I look aroun at development that's going around that area, Lundgren Bros as you know purchased the Song property and this is 100 plus acres ... and I believe the density that they achieved on that very interesting piece of property, which I think is fairly well known to this , commission, was about 1.1 houses per acre. We have 25 acres bordering TH 41, part of which the new Lake Lucy Road would come through, which is the old Westside Baptist parcel. And in reviewing that with a few different developers we have again arrived in terms of preserving th � naturalness of the land,= ,which is one of the perquisites frankly before I'm going to sell thz t property to anybody. You end up with about 1.1 houses per acre in the final analysis. You look at the Gestach and Paulson, all this terrain is the same. It's different , but it's the sam�. It's very hilly and it's',very interesting and it's very beautiful. The Gestach and Paulson, w �'ch is right on the north side, so I've talked about the south, the west and now the north s de of where we live. Th. ey have 25.85 acres with 3 outlots. They're looking at 21 single farr 'ly lots. So you throw in the 3 outlots and maybe that will bring it up to about 1.1 house per acre in the final analysis. It feels like there is almost some agreement that exists somewhere that dictates x number of lots and on and on and I submit to the Ryans and to this commission that there does not need to be an economic hardship concern in my view at all. I think that the property, if developed in a manner which fights nature less and leaves the natural beauty present, for a potential homeowner in fact increases the value of that property enormously for someone who desires that kind of a setting for a family home. And therefore I would really suggest that this commission take a look at what has been transpiring and what is transpiring, if you will, right'i4round that area as far as the type of land, the topography and how that has ended up equating to actual lots in the final analysis and I think you'll find that .1 is probably a fairly accurate number and the reason is because of the topography. d I submit that these other folks have worked hard at protecting it. I can tell you that the Lu dgren Bros have to the south of us because I've been a big part of that door having the process with th( Song's. I don't really want to live right next to, spent money and the i' a and the effort to protect the environment with our home site area there, which is subs tial. We've protected it 'I think as well as anyone can. And then have the field leveled off and fill with houses is destroying the flow and the rthym of that adjacent particular area. I just, I don't think it's necessary. I don't think there's an economic hardship question at stake at all. That there are buyers out there who will enjoy and will pay the price for that natural auty. And there are other areas that simply don't have that kind of terrain , 15 Planning Commission Meeting - September 7, 1994 to that extent. Severity at exists in that area. So I would ask that the commission tY ss on give that some thought and consider the ratio that has been working for other people in the immediate ' area as a maximum. And I don't know that that property even, I don't know what the ratio should be on this particular piece. 1.1 there may not be absolutely accurate. I haven't sat down and figured it out because it's not...Relative to the views from our property looking rnorth. Until there is more of a plan that exists and this commission and others perhaps are seriously interested in approving, I don't think I need to spend your time talking about whether or not some sort of tree barrier or some sort of screening is necessary or not from my point of view. But I don't know that that's been discussed at all up to this point and I would simply like to be on record as saying that may or may not be an issue ... spills down into something specific. Thank you. Scott: Thank you. Would anybody else like to speak at the public hearing? Yes sir. ' Peter Davis: My name is Peter Davis. I live at 6640 Galpin Blvd. I'd like to reiterate several of the points that have been raised by Sam Mancino and some of the others who 1 spoke here tonight. I'm representing myself as well as several neighbors who weren't able to make it to the hearing tonight who all have a deep concern over the original concept or design of this proposed subdivision. No one has an interest in standing in the way of the development because we all know it's coming. But it seems like in the case of some of the sections of the City Code, particularly when I call out Section 1860, which specifically says, it talks about the lots should be placed ... to protect natural amenities such as vegetation, wetlands, steep slopes, water courses and historic areas. I believe the intent of that, and I really kind of look at the intent as being lots should be placed. Not we'll take some land and we'll put as many lots on it. And I wanted to reiterate a deep concern that this seems to be driven from the standpoint of trying to increase the density for the number of homes rather than really trying to preserve that land and all of the other constituencies that represent an ecosystem or the wildlife as well as the aesthetics of the area that this... represents. That was really the extent of my comment. Was to reiterate the one section of the code as it related to sort of are lots and topography and coming in which order... subdivision. Scott: Okay, thank you. Any other comments? Yes sir. Marty Gustafson: Good evening. My name is Marty Gustafson. I live at 6691 Galpin, which is right on the northeast corner of Lake Lucy and Galpin Blvd. I'd just like to restate what the previous speakers have said. That the beauty of the land that the Ryan's own is in the rolling topography. And to go in and bulldoze that and just kind of level it all off, to me is just like raping the land. If you look at the development south. I can't recall the name of it but south of Prince's property, that land was pretty much flat to begin with and it just, it's ' not unpleasant but it's just boring. You know you've got a difference in elevation of 20 or 16 Planning fission Meeting - September 7, 1994 30 feet probabl' in the whole development and everybody can look out their front window into their neighbor's front window and right on down the street And it just, to me is boring. And most every night I can watch the deer walk through the Ryan's property and it's just the roll is just beau tiful to watch the sunset through the trees and I would hate to see that get leveled. My o er concern is drainage. If the wetlands are filled in, where's that water going to go? I imagine it's either going to go 'through my property or through Mezzenga's. Both of us abut Lake Lucy Road. Is there going to be massive trenching or digging? And if it is, it's all going d wn into Lake Lucy. You know that swamp is filling up fast The lake is filling up fast ji st because of all the vegetation. You can watch it from year to year. And pretty soon that s, there isn't going to be any water showing at all. So I would like to see whatever drainage is required stays on the property and not get drained off and create problems for someone else. Thank you very much. Scott: Would anybody else like to make any comments? Yes sir. Lynn Rothberger: Lynn Rotherberger. I'm at 6681 Galpin and really only had just one comment to m e. I've heard a lot of the speakers tonight speak of the surrounding properties. Lake. Lucy Highlands, etc and matching the topography that is there. It seems to me that there is minimum acreage requirement on that land of something about 2 1/2 acres and the plans d at I've seen, I don't see any attempts at all to be a match of that in the proposed devel pment and I just would have a concern about the density or the amount of density and po lation of housing that's going to come into that property. I too very much enjoy the wildlife and the sunsets and the topography itself and I guess I have to agree with all the rest of tt a speakers that you're going to have to pretty well flatten that out to put housing in them and that concerns me. Scott: And yottr comment, part of the matter in front of us is the rezoning of the property from RR to RS '-, which means Rural Residential which is big lots. RSF is 15,000 square foot minimums so that's part of the process. Good, thank you. Any other comments? Seeing none, m iiy I have a motion to close the public hearing? Ledvina motion i Conrad: I thins here. Staff has can be tweaked guess I'm not g quite a while. natural asset it Nutting seconded to close the public hearing. All voted in favor and the The public hearing was closed. it's, I don't want to get into details tonight I think there are a lot of details -lovered them. The applicant has covered them. There are a lot of things that with lots. A lot of things that can be tweaked based on staff report and I )ing to spend my time going through item by item because that would take think when you note what the property looks like, you know what a real > out there, and I don't see this plan really taking advantage of the natural 17 1 Planning Commission Meeting - September 7, 1994 assets so you know really bottom line, I have to turn it down. I'm not getting into the details in terms of the individual plan tonight. They preserve very few trees. There's massive 1 grading. They did not fit with the surrounding neighbors. And you know, those three things just all by itself Mr. Chairman make this, I don't think this is an appropriate subdivision at this time. The other thing that I'm concerned with, and I want to make it a natural amenity. tThe area is just so beautiful. I want to make sure that when it does develop, that our trail system is taken advantage of that throughout. That's real important so I think we not only have, the developer has an opportunity to not only make the money and not only do it well fitting with the natural environment, but also to give the community something in the process. And again, a lot of us have been out there. It is just a terrific area. It is one of those unique spots in Chanhassen and I don't think we, this plan meets any of our base criteria for a subdivision fitting with the natural surroundings so Mr. Chairman I'm going to be as brief as I can and say this subdivision should be turned down. Scott: Matt. Ledvina: Thank you. I have some questions for staff. Last time we met we discussed the feasibility study and I heard the applicant talk about a supplement feasibility study and preferred northerly route. Dave, could you give us a little more background and what was the actual feasibility recommendation. I don't want to get into it in real detail but I just want to understand exactly what was the preferred alternative. Hempel: The feasibility study looked at two alternatives for extending Lake Lucy Road from Trunk Highway 41 to Galpin Boulevard through what was called the Westside Baptist Church site which is on the far west side immediately adjacent to Trunk Highway 41. That was the ' particular parcel that was, the two alignments were discussed. The southerly alignment and northerly alignment. The southerly alignment was closer to Mr. Carlson's property and had a base and a slope and significant trees to the south of it. There was also a graded wetland that 1 was... The northerly alignment through that parcel with the existing driveway access on the site, it tended to meander the road a little bit more. The only alignment that I'm aware of through the Ryan parcel is a southerly alignment but potential for the northerly alignment was also given through this outlot of this Gestach - Paulson development, Brendon Pond to leave the flexibility for Lake Lucy Road to be extended through the Ryan parcel somewhere in this area. It wasn't officially mapped but the consulting engineer reviewed it and the proposal for the feasibility study showed the southerly alignment for the Ryan parcel. The two alignments that were reviewed by the City Council was the northerly and southerly alignment across and ' into the Westside Baptist site and the Gestach- Paulson site. It's leaving the opportunity open as you continue to the east. 1 18 Planning Co ; ssion Meeting - September 7, 1994 Ledvina: So th re really wasn't two alignments that were mapped out for this property, is that correct? There was only this southerly alignment? Hempel: As far as I'm aware... Ledvina: Okay. And then as it relates to the alignment, the applicant has suggested that that would amount to a wetland filling. Was at also identified in the feasibility study? Hempel: M understanding, based on the conversations with Bill Engelhardt that there was ' P Y no intention of IMing the wetland with the southerly. Ledvina: Okay. So in other words, it would be relatively easy to realign that roadway slightly to the north, whatever it takes, 10 or 15 feet or 20 feet, to avoid that wetland filling. So we're really not talking about trading off wetland filling in choosing that alignment, is that correct? Hempel: That' correct. Ledvina: Okay. Now I want to understand the conservation easement. You've got quite a long description here Bob and does it cover, does it indeed describe the northerly 30 feet of the plan? Generous: Yes. Ledvina: It does, okay. That's really all I need to know. Okay. Because it talks about a lot of different chunks here and that's the legalese of describing which lot that covers I'm sure. , Your recomme (Nation number 16, it says plat the land west of Lot 14, Block 2 as an outlot. Are you talking about, now I know this relates to the western portion of Outlot 6 as they've hand drawn it here. Now you're saying put a property line and make that long narrow chunk an outlot, is that correct? Generous: Co ect. Ledvina: Okay I wanted to make sure that was clear. Let's see. I think overall, I'm leaning towards some of the core issue as it relates to the development of the site as proposed. I woald agree with the commentors from the public. Also Ladd's comments. I feel that as we discussed and recommended the applicant pursue last time, we all agreed that ' the Lake Lucy oad alignment provide the most sensitive course for this road through this parcel of this si e. We suggested that the applicant go ahead and look at alternative ways of preserving that ull in that western portion of the property. And I do like the idea of going in ' 19 Planning Commission Meeting - September 7, 1994 with a street off of Jennifer Way with potentially some private drives. That way I think that could provide access to that area and again preserve that. I don't know procedurally how I ' would propose to do this. If we would add conditions and send it along or that in such a condition that we'd want to see it tabled or I'm just thinking out loud here a little bit on procedurally how this might be handled. But I think overall we need to have some work fdone on this plat before it can really be viewed as an acceptable environmentally sensitive proposal. Scott: What would you like to see? What would you suggest for the applicant? Ledvina: Well I don't, I'm suggesting that we table this and see a rework of the design for this western portion and we've made that suggestion previously and I don't know where the applicant is at with that but I'd be willing to look at it one more time. ' Scott: Ron. Nutting: Some of Matt's questions answered some of mine. I think there are a lot of details. I think the plan we're looking at is, I think counsel for the applicant has indicated that you know we're being asked to approve what staff has recommended and I don't think staff has recommended this as their first choice. They've done a second choice because there was not a willingness to look at the preferred southerly alignment of Lake Lucy Road. Having been to the site and looking at it and from our recommendations last meeting, the southerly alignment seems to make the most sense to me. With that in mind, and I guess I echo Ladd's comments and I think that of a lot of the citizens here. I don't think this development does the best job of dealing with the existing topography or the surrounding developments so whether it's a tabling issue or a chance to rework or that we deny it, I think that's maybe a procedural question that I'd put to my other members but I'm not ready to go forward with this plan. I am open to seeing a rework of the plan. Scott: And what sort of direction would you give? Nutting: Well, I can't develop it for them. I'm not a developer but what I see is not consistent with surrounding developments and topography. There have been some suggestions put forth but that's really for the developer and their advisors to look at. If it's an extension of James Court into the westerly portion of the land, I can't say for sure and I can't sit here and try to visualize it and say do this and all will be well. So I guess the main concern is just that it doesn't make sense with the land and the surrounding development. Scott: So you 'r e th inkin g primarily manly make be tter use of the existing topography? Is that one that you're getting? 20 Planning Comm2ssion Meeting - September 7, 1994 Nutting: Absol tely. Scott: Okay. Nutting: Which will impact density. There's a lot of issues there. Scott: Okay. Just a question. Kate, when was this preliminary plat and rezoning, when was that presented to staff because I know we've got a, we have two different timeframes that we deal with. Aanenson: The ordinance states that you have 45 days to make a recommendation to the City Council ... and I believe that date was August 17th. So accordingly... you have one more chance to review which is September 21st... Scott: Okay. I'm not going to echo any comments. I'd like to have a motion please. Unless you wan to discuss. Obviously tabling we'd get it back. We may see the same thing all over again. Denying it automatically sends it to the City Council with our comments on why we're deny g it so. Nutting: I would be open to tabling it. I think the property is going to be developed. I mean it's not a issue of developing it or not It's a question of getting something that makes sense so. Scott: Okay. 1 ou're thinking tabling? Conrad: Mr. Chairman, why don't you ask the developer what his choice is. Ed Ryan: Do y u want me to step up to the podium? Scott: No, that won't be necessary. Ed Ryan: I gu s I would prefer you approve it obviously but if you're not willing to approve it, I guess I'd prefer you deny and then we have the opportunity to go forward and that's what we ant. Scott: Okay. I have a motion please? Conrad: We do have a rezoning. I'll make the motion to deny the preliminary plat but do we need to discuss the rezoning issue? , 21 Planning Commission Meeting - September 7, 1994 IAanenson: Yeah. Scott: Yeah, we could not, this preliminary plat would not fit RR zoning so. Aanenson: If you don't approve the plat, then the Council wouldn't have. If the Council chooses to approve it, you haven't recommended on the rezoning... Conrad: Why should I recommend approval on the rezoning if I don't like what's going to ' go on it? Aanenson: You can make a different motion to ... whether you choose to approve or deny the Council's still going to make their own decision so in principal, if you want to go on record and make some recommendations ... but not to make any recommendation. ' Conrad: I'm not sure what signal I'm sending when. I not saying that this shouldn't be rezoned. It's just that this particular plat is not what I want to see so that's always been ' confusing to me. You know it's like what signal am I sending. Scott: Usually it's more consistent if both are acted upon the same way. ' Ledvina: Well if you look at as a package, I guess. Is that how you would prefer it? ' Aanenson: Yes. If you don't ...no matter what motion you state, whether you approve or deny the rezoning, Council still has the right to... ' Conrad: Well we'll just administratively go through this. I make a motion that we deny the rezoning of Case #94 -3 rezoning 37.92 acres from RR, Rural Residential to RSF, Single Family Residential. Scott: Okay. Is there a second? Nutting: Second. Scott: It's been moved and seconded that we deny the rezoning. Is there any discussion? Conrad moved, Nutting seconded that the Planning Commission recommend that the City Council deny Rezoning #94 -3 rezoning 37.92 acres from RR to RSF. All voted in favor and the motion carried. Scott: Can I have another please? 22 Planning Commission Meeting - September 7, 1994 Conrad: Yes, I make a recommendation the Planning Commission denies approval of Preliminary Pla #94 -7 based on our previous comments in terms of the plat's lack of sensitivity to the surrounding, which includes the mass grading. It's lack of sensitivity to the neighboring cor imunity and it's non, and the fact that it didn't incorporate our primary location for Lake Lucy Road. Scott: Okay. I9 there a second? Nutting: Conrad moved Nutting seconded that the Planning Commission recommend that the City Council d6y Preliminary Plat #94 -7 based on the previous comments regarding the plat's lack of s nsitivity to the surrounding area, mass grading and the location of Lake Lucy Road. 1 voted in favor and the motion carried. Scott: Counci an Mason, thank you for taking notes. Just a. Generous: There's a WAP, wetland alteration permit. Scott: Don't u e that acronym in that way again. Ledvina: I move that we deny, or we recommend denial of Wetland Alteration Permit Section 20 -407. Scott: Okay, isl there a second? Nutting: Ledvina moved, d Nutting seconded that the Planning Commission recommend that the City Council d ny Wetland Alternation Permit #94 -3. All voted in favor and the motion carried. Scott: Editorial comment. The reason why we're denying this and passing this on is that we did not believe that we're going to get anything better back from the applicant so we're basically dumping it on our colleagues in the City Council and I would encourage any of you to follow the issue because the final decision is not made here. It's made at the Council level and I'd like to thank you all for coming for this issue. 23 CHARLES W. PLOWS, CONSULTING ENGINEER 9180 LEXINGTON AVE. N.E, CIRCLE PINES, MN 55014 (612) 785 -1043 FAX 786 -6007 September 14,1994 ►`� Bob Generous ; . City of Chanhassen 690 Coulter Drive Chanhassen, MN 55317 Re: Shamrock Ridge, Preliminary Plat Dear Mr. Generous, Per our meeting on Monday, September 12, at your office we have made further changes to the plans for preliminary plat approval. It was staff's concern that the north boulevard area on Lake Lucy Road was not wide enough to comfortably provide space for the proposed 8 foot wide trail. To allow ample room it was agreed that the roadway would be shifted southerly. The roadway has been revised from 60 feet to 85 feet at it's closest point from the north property line. In conjunction with moving the roadway it was also agreed that a private drive in place of Gwendolen Court would be used. This will remove one lot and allow more room for spacing of four lots in this area and pull the toe of slope further away from the wetland. The connection of Lake Lucy Road to Brendon Pond was reviewed and a curved alignment as shown on the revised plan will provide an easy connection. - The private road serving Lots 4, 5 & 6, Block 4 has been moved outside of the tree preservation area along the north property line. The storm sewer discharge into the westerly treatment pond has been combined into one discharge pipe. A maximum 4:1 access slope to pond is being provided. There have been numerous changes made to the preliminary plat and grading plan to address requirements and concerns by staff. Enviromental concerns have been a priority as the process has progressed to this plan. Preservation of trees, wetlands and maintaining some of the large variations in elevation throughout the site has been a part of the present design. Mr. Ge page 2 Based on understar plat. Please ca Sincerely is 14,1994 iur September 12th meeting andthe attached revised plans it is our ing that staff will recommend approval of the proposed preliminary with any questions or comments regarding the above.
