Numerous issues were raised by the Planning Commission, residents, and staff. These issues included excessive grading, tree loss, environmental concerns, and variances. The applicant listened to the issues and attempted to address them through a revised plan. The application was revisited by the Planning Commission on May 3, 1995. At that meeting, staff prepared a sketch plan to act as a guideline to improve the plat. The recommendation in the re port was based on the layout pre pare d by staff rather than the plan pre pare d by the applicant. The Planning Commission unanimously agreed that the plan was not ready to be sent to City Council. Action on the application was tabled and the applicant was directed to modify the plans and incorporate recommendations made by staff. On May 17, 1995, the Planning Commission reviewed a plan that incorporated most of staff's recommendations. The proposal was approved with conditions. This staff report has been modified to address the changes. PROPOSAL /SUMMARY The applicant is proposing to subdivide 14.53 acres into 18 single family lots and two outlots The property is zoned RR, Rural Residential and the proposal calls for rezoning it to RSF, Residential Single Family. The average lot size is 30,122 square feet with a resulting gross density of 1.2 units per acre. Most lots meet the minimum requirements of the zoning ordinance with the exception of Lot 2, Block 2. This lot has an average depth of 123 feet. The zoning ordinance requires a minimum depth of 125 feet. These variances can be easily eliminated by shifting Lakeway Drive to the east. The site is located south of Lake Lucy Road and north of Lake Lucy. Access to the subdivision will be provided via a public street /cul -de -sac south of Lake Lucy Road to service the proposed lots, as well as internal private streets. The majority of the site is wooded with a diverse range of species and ages. According to the proposed plans, the minimum tree canopy to be maintained is 46% or 5.23 acres. Staff calculated 1.32 acres of trees to be removed in excess of the minimum requirements. Additional tree replacement will be required. In reviewing this plat, staff worked with the applicant and offered some suggestions to minimize the impact on the natural features of the site. Some of these options were locating a storm pond on the site, moving the cul de sac to the west to avoid some mature trees, custom grading house pads, and using variances to minimize impacts on the site. The applicant incorporated these suggestions into the plans, however, additional work was required to further improve the plan. Staff then prepared a modified sketch plan to give the applicant additional direction and recommendation to further improve the plat. The applicant 7 1 Lake Lucy Estates 1 May 17, 1995 Page 3 1 incorporated these suggestions into the revised plans. Staff has offered additional suggestions to reduce the height of some retaining walls, minimize grading, and reduce impact on some mature trees. 1 Changes that took place include the following: 1 * The ultimate number of lots to be served via Lakeway Court which is a private street is five vs. three. * The previous plan showed 10 lots with a 20 foot front yard variance. The 1 current plan shows a total of 3 lots with a 20 foot front yard setback variance. * Tree plan has been revised by saving trees in clusters as well as individual trees. However, the overall tree loss has not been reduced. 1 * Grading has been reduced through custom grading of the lots and shifting house pads and dwelling type on the lots. * Filling on Lots 6 and 7 has been reduced. The type of home is designated as a 1 lookout rather than a walkout, which requires less fill. The revised plans are another step in the right direction; however, additional revisions could 1 be incorporated to further improve the plan. Staff will be providing recommendations to minimizes grading and variances. Staff is recommending approval of this application with conditions outlined in the staff report. 1 REZONING i The applicant is proposing to rezone the property from RR, Rural Residential to RSF, Residential Single Family. The area to the north is zoned Residential Single Family to the east and west is zoned Rural Residential and is guided for Residential Low Density. 1 The 2000 Land Use Plan shows this area designated for development as Low Density Residential, 1.2 - 4.0 units per acre. The applicant's proposal has a gross density of 1.2 units 1 per acre and 1.98 units per acre net after the streets and wetlands are taken out. This area is in the MUSA area. Staff is recommending approval for rezoning to RSF 1 consistent with the Comprehensive Plan. 1 PRELIMINARY PLAT The applicant is proposing to subdivide an 14.53 acre site into 18 single family lots and two outlots. The density of the proposed subdivision is 1.98 units per acre net after removing the 1 roads (2.28 acres) and wetlands (3.16 acres). All lots exceed the minimum 15,000 square feet of area, with an average lot size of 30,122 square feet. The depth of the lots meet ordinance 1 requirements with the exception of Lot 2, Block 2. This parcel has an average depth of 123 1 Lake Lucy Estates May 17, 1995 Page 4 feet. The ordinance requires a minimum lot depth of 125 feet. The applicant shall adjust the plan to eliminate the lot depth variance. The previous plan submitted by the applicant reflected four walkout lots along the lakeshore. Two of those lots have been revised to show lookout -type dwellings verses walkouts. This will reduce the amount of filling required on the site. The house pad on lot 7, Block 2, has been shifted closer to the westerly property line. This will result in saving a number of mature trees along the east property line. Staff is supporting a 10 foot side yard setback on the westerly lot line of Lot 7, Block 2. This will push the house pad even further away from the cluster of trees located along the southeast corner of the site. Some of the recommendations attached to this proposal will reduce the fill on some lots and shifts the house pads into areas that would further minimize impact on the tree canopy. The 20 foot front yard setback variances on some of the lots is promoting the preservation of trees and wetlands. We believe it is warranted. There are a total of three 20 foot front yard setback variances as was shown in the sketch plan prepared by staff. The street grades and alignment could be modified slightly to the south, closer to Lot 9, to minimize impact to trees located on Lot 4, Block 1 and within the proposed alignment of Lakeway Court. Lots 5, 6, and 7, Block 2, located to the south of the cul -de -sac, are proposed to be served via a private street, as well as homes proposed on Lots 10 and 11, Block 2 and Lot 2, Block 1. The lower portion of the property located to the east of the subject property (Morins) can only gain access to a public street through the subject property. The adjacent property has the potential to subdivide into three lots. Two of those lots will utilize the same driveway as proposed Lots 10 and 11, Block 2 and Lot 2, Block 1. The ordinance allows a maximum of 4 homes to be served via a private drive. The plan proposes 5 lots to be served via a private street. This will minimize grading and preserve trees in that area. Staff supports granting a variance to allow up to five lots accessing a private street. Lots 5 and 6, Block 2, show a 20 foot front yard setback. The zoning ordinance requires all neck lots or lots served via a private driveway to have a 100 foot width. The ordinance further states that the 30 foot front yard setback shall be measured from the point where the lot achieves that 100 foot width. The setback for Lots 5 and 6, Block 2, can and must be revised to reflect a 30 foot front yard setback. Although the proposal is consistent with the Comprehensive Plan, and generally consistent with the Zoning Ordinance, we believe that revisions as recommended within this staff report should be made to minimize impacts to the natural features of the site. WETLANDS There are 2 wetlands delineated on -site and they are as follows: Lake Lucy Estates May 17, 1995 Page 5 Wetland A is a natural wetland located on the property just east of Lots 8 through 11 along the southeastern portion of the property. The wetland is approximately 5.3 acres and is characterized as an inland shallow fresh marsh. Approximately 1.7 acres of the wetland is t located on the property. Wetland B is the natural wetland complex that borders the Lake Lucy shoreline. The wetland ' is above the ordinary high water elevation for Lake Lucy, and therefore, is not within DNR jurisdiction. Approximately 1.4 acres of the wetland is located on the property. L I Since both of the wetlands are classified as natural, the buffer strip required shall be 10 to 30 feet wide with an average width of 20 feet. It is recommended that any disturbed areas of the buffer strip be seeded with a mixed variety of natural upland vegetation. Although these wetlands will not be filled or excavated as a result of the development, erosion control and maintenance on the erosion control is a key factor in protecting wetlands. Type III erosion control shall be provided around the wetland at the start of construction and maintained until vegetation is fully re- established. SURFACE WATER MANAGEMENT PLAN (SWMP) The City has adopted a Surface Water Management Plan (SWMP) that serves as a tool to protect, preserve and enhance water resources. The plan identifies, from a regional perspective, the storm water quantity and quality improvements 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 the 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. The development will be required to be constructed in accordance with the City's Surface Water Management Plan. Storm Water Quality Fees The SWMP has established a water quality connection charge for each new subdivision based on land use. Dedication shall 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 market values of land in the City of Chanhassen plus a value of $2.50 per cubic yard for excavation of the pond. The City has had discussions with the applicant's engineer on the water quality ponding. The proposed SWMP water quality charge of $800 /acre for single- family residential developments may be waived if the applicant provides water quality treatment according to the City's SWMP standards. The C Lake Lucy Estates May 17, 1995 Page 6 stormwater quality pond shall be designed to retain up to 75% phosphorus according to the Walker Pondnet model. Storm Water Quantity Fees The SWMP has established a connection charge for the different land uses based on an average city -wide rate for the installation of water quantity systems. This cost includes land acquisition, proposed SWMP culverts, open channels and storm water ponding areas for runoff storage. Single family residential developments will have a connection charge of $1,980 per developable acre. The total gross area of the property is 16.34 acres; however, 4.86 acres is wetland. Therefore, the proposed development would then be responsible for 11.48 acres resulting in a water quantity connection charge of $22,730. This fee will be due payable to the City at time of final plat recording. GRADING & DRAINAGE The applicant has incorporated many design changes that staff had proposed previously. Some of the changes include custom grading the wooded lots, increasing the street grades up to 10% to conform better with the existing ground contours which results in less grading, adjusting of building pad elevations and /or changing the dwelling types to conform with the existing ground to minimize grading, modify the street and cul -de -sac alignment to accommodate a water quality storm pond (Walker basin) for pretreatment of storm water prior to discharging into the wetlands, adjusting lot lines and building types where significant trees can be saved, combine the sanitary sewer alignment from Morin's property with the private street (Lakeway Court). The plans have been prepared with a 50 -foot right -of -way, again, which is less than the City's standard right -of -way in an attempt to preserve trees and lessen the amount of grading. Staff believes that this compromise in right -of -way width will reduce grading and minimize impacts to the site. Another alternative would be to reduce the building setbacks. Staff has also worked on the street grades which we believe will minimize grading, trees loss, and the amount and height of retaining walls. The applicant should incorporate street grades throughout to conform better with the existing terrain. Staff would be happy to work with the applicant's engineer to assure that this is accomplished. Staff also considered shifting the intersections of Lakeway Court and Lakeway Drive as well as Lakeway Lane and Lakeway Drive southerly by approximately 20 feet to match existing grades better and lessen the sanitary sewer depth. Lakeway Court is currently proposed with up to 7% street grades. The relocation of Lakeway Court further to the south will, however, result in the loss of an additional 14 -inch oak tree on Lot 9, Block 2 but will in return save two significant oak trees which are proposed to be lost on Lot 4, Block 1 (24 -inch and 26 -inch oaks). Lakeway Court also needs to provide for a turnaround acceptable to the City's Fire Marshal. A temporary turnaround could be created on site (Lot 2, Block 1 or Lot 11, Block 2) until the Morins further subdivide. Lake Lucy Estates ' May 17, 1995 Page 7 The southerly private street ( Lakeway Drive at the end of the cul -de -sac) is proposed to serve Lots 5, 6 and 7, Block 2. The applicant has revised the grading plans to limit fill to only the house pad areas and the service drive. Previously, the applicant had proposed up to 8 feet of fill in this area. Staff has reviewed this proposal and believes the applicant has minimized ' the impact to this area short of reducing the number of overall lots at the end of the cul -de- sac. In order to provide sanitary sewer service to Lots 5, 6, and 7, Block 2, up to 4 feet of fill will be required to provide adequate cover to prevent freezing. The homes in the cul -de- sac (Lots 5, 6, and 7, Block 2) have been designed to eliminate the need for an ejector pump as well. House dwelling types on Lots 6 and 7 have been revised from walkouts to lookouts ' to further minimize grading. Surface water runoff from Lakeway Drive will drain between Lots 5 and 6, Block 2 towards ' Lake Lucy. Staff feels there is a more than adequate buffer to pretreat the amount of runoff generated from the additional homesites prior to discharging into Lake Lucy. The applicant has further designed the stormwater basin located on Lot 3, Block 2 which is proposed to ' convey and pretreat stormwater runoff from the street and front yard areas of the subdivision. This pond will then outlet underneath Lakeway Drive easterly back to the wetlands to assure recharging of the wetlands. At the Planning Commission meeting residents were concerned ' about the runoff being directed back into the wetland and being detrimental to wetland. Staff believes that it is necessary to route the treated stormwater runoff back to recharge the wetland. The exact location of the outlet pipe underneath Lakeway Drive is subject to ' change. Staff will locate in the field a path for the storm sewer to minimize impacts to the existing vegetation. This typically is done in conjunction with review of the final construction plans. ' Other concerns from the residents were location of numerous existing groundwater springs, storm sewer calculations, water quality, environmental impacts, erosion control measures, ' height of the retaining walls. The plans as submitted do not show erosion control fence; however, staff will require fencing around the perimeter of the grading limits on the final grading plans. Storm sewer calculations are typically not submitted for staff review and approval until the final construction plans are prepared. Typically with preliminary plat approval, there are numerous revision in grading and lot layouts that will change the storm sewer calculations. Staff is confident that there is adequate room being provided for the ' stormwater pond to pretreat the runoff prior to discharging into the wetlands in accordance with the City's SWMP. Within the City of Chanhassen groundwater is evident typically with each development. This groundwater is not necessarily springs. The City with its rolling ' terrains and heavy clay soils frequently contain areas of groundwater. Subdivisions typically deal with groundwater through the use of either storm sewers or draintile systems to convey the runoff to the stormwater ponds and /or wetlands to maintain the groundwater migration pattern. Lake Lucy Estates May 17, 1995 Page 8 The applicant is proposing boulder retaining walls up to 12 feet in height along Lakeway Lane /Drive (Lot 3, Block 3). Staff believes that with revised street grades, these retaining walls can be reduce in half. This will also minimize impact to existing trees adjacent to boulder retaining walls. To preserve existing vegetation, staff is proposing the homesites on Lots 3 and 4, Block 1 and Lots 8, 9, and 10, Block 2 be built lower than the street to reduce the amount of fill required in the front yards. Typically, staff has reservations regarding placing the homesite lower than the street due to drainage concerns, however, a grading and drainage plan could be developed with each individual homesite to ensure proper drainage around the structures. A good example of this within the City is along Bighorn Drive within the Shadowmere subdivision. Staff has also further reviewed access and utility service to the "Willis parcel" west of this development. It appears the parcel may be further subdivided once sewer and water is available to the parcel. The applicant has incorporated staffs' recommendation by providing a 50 -foot right -of -way ( Lakeway Lane) to extend utility and street service. The Willis parcel would be required to access this street pending further subdivision of the parcel. Drainage off Lakeway Court is proposed to drain to a low point between Lots 10 and 11, Block 2. Staff believes the road should be tilted to provide sheet drainage across the street between the house pads towards the wetlands. Most of this runoff is from backyards or lawn areas which requires minimal treatment. The buffer strips between the houses and the wetlands will be sufficient in pretreating runoff prior to reaching the wetlands. Typically, with the soil conditions on hilly terrains, ground water may be of concern. The City requires a drain tile system behind the curb and gutter for homes which are not adjacent to a wetland /pond. The drain tile system provides an acceptable means of controlling sump pump discharge from the homes as well as improve the street subgrade. The building setback lines, buffer strips, and tree fencing needs to be denoted on the final grading and drainage plans prior to final plat approval. EROSION CONTROL Erosion measures and site restoration shall be developed in accordance with the City's Best Management Practice Handbook (BMPH). Staff recommends that the City's Type III erosion control fence which is a heavy duty silt fence be used around the wetlands for maximum protection. The final grading plan shall incorporate erosion control fence around the perimeter of the grading limits. In addition, tree preservation fencing should be denoted on the grading and drainage plan as well. 7 Lake Lucy Estates May 17, 1995 Page 9 ' UTILITIES Municipal sanitary sewer service is proposed to be extended from the Coey parcel which was ' recently subdivided into Point Lake Lucy. The Coey parcel is located approximately 200 feet east of this site. The sewer line to date has not been extended to service this parcel from the Coey parcel. Sanitary sewer is proposed to be extended this spring, early summer through the ' Coey parcel and deadend at that the property just east of the development ( Morin's). The exact alignment of the sewer line has now been staked in the field up to the Morin's property. The alignment minimizes tree loss and impacts to the wetlands and Morin's property. The ' applicant has been working with the Morins to acquire the necessary utility easement for this extension in order to proceed with the project. The sanitary sewer will need to be extended through the Coey and Morin properties. Without the sewer, this project would be considered ' premature for development. A condition has been added in the staff report that final plat approval will be contingent upon sanitary sewer being extended through the Coey and Morin properties. The plans have relocated the sanitary sewer line to follow Lakeway Court in an ' effort to minimize impacts to the existing vegetation. Municipal water service is available to the site from Lake Lucy Road. The plans propose on ' extending water service throughout the development. Detailed construction plans and specifications will be required in conjunction with final plat approval. The construction plans and specifications shall be prepared in accordance with the City's 1995 edition of the Standard ' Specifications and Detail Plates. Final construction plans and specifications will be subject to City Council approval. The applicant will be required as a part of final plat and construction plan approval to enter into a development contract and provide the City with financial ' securities to guarantee conditions of approval and installation of the public improvements. The development contains two existing homesites (Tichy and Christensen). Both of these ' homesites are currently on their own well and septic system. The existing home on the westerly portion of the site (Lot 1, Block 2 - Christensen's) is proposed to be removed. The other home (Tichy) is proposed to remain on Lot 1, Block 1. Both on -site well and septic ' systems will have to be abandoned in accordance with the City and State health codes in conjunction with this development. The well and septic on Lot 1, Block 2 will have to be abandoned in conjunction with site grading. The well and septic system on the Tichy ' property (Lot 1, Block 1) may be delayed since the construction activities appear not to impact the systems. However, city ordinance requires properties within 150 feet of a municipal sewer system must be connected to the City's system within 12 months after the ' system becomes operational. Connection to City water is not required until the well fails. ' The sanitary sewer to serve this development will be designed and constructed to service the Morin's property as well as the properties to the west and north of the site. The applicant has shown sewer and water extension west of the cul -de -sac towards the Willis property. Staff ' has reviewed the utility service to the Willis parcel and feel Lakeway Lane is the appropriate Lake Lucy Estates May 17, 1995 Page 10 extension point for utility service. The sanitary sewer elevation should be at 996.0 at the end of Lakeway Lane. This can easily be changed on the plans and is typically reviewed during the final construction plan review process. STREETS Access to the development is proposed from Lake Lucy Road. This road is classified in the City's Comprehensive Plan as a collector street. Street right -of -way on the public street has been reduced from the 60 -foot requirement to 50 feet wide to reduce grading and tree loss. Staff has evaluated this compromise with the revised plans and believes the reduced right -of- way is warranted. The plans are also incorporating the use of private streets to service portions of the development and adjacent parcels. City ordinance provides up to four homes to be serviced off a private street. A turnaround acceptable to the City's Fire Marshal will also have to be provided. The private street will reduce impacts to the wetland and tree loss versus the public street. Staff believes the use of private streets to service Lots 5, 6 and 7, Block 2 is warranted to reduce impacts to the area. The house pad on Lot 7, Block 1 has been relocated westerly as shown on staffs layout to minimize grading and tree loss. The use of a public street in this area would destroy the natural features. In addition, Lots 6 and 7, Block 2 would be marginal lots due to setback requirements from wetlands and the street. Staff believes the applicant has followed the layout prepared by staff to minimize the environmental concerns. Another private street is proposed to service three lots (Lots 10 and 11, Block 2 and Lots 2, Block 1) and the Morin's parcel to the east. The Morins and staff have reviewed the development potential of the Morin's parcel and it appears that the site may be further subdivided into two additional lots. Therefore the private street ( Lakeway Court) as proposed would be serving up to five homes which exceeds the City's ordinance. Staff believes there is no other way to create a street system to serve these lots which would minimize impacts and therefore recommends a variance be granted for up to five (5) homes accessing Lakeway Court. A turnaround which meets the City Fire Marshal's requirements will be necessary at the end of Lakeway Court. If the Morins are not in favor of the turnaround at this time, a temporary turnaround could be developed on Lot 2, Block 1 or Lot 11, Block 2 until the Morins are ready to subdivide. Future access was also considered for the parcel west of the development (Willis) which is currently for sale. The Willis parcel currently gains access from Lake Lucy Road via a long gravel driveway. Part of the driveway is actually located within the proposed subdivision and is shown through Lots 1, 2 and 3, Block 3. The Willis driveway access on to Lake Lucy Road is across from Yosemite. This intersection has substandard sight distance which makes it difficult to safely turn to and from the property. Eventually, when the Willis parcel further subdivides, staff will recommend that the driveway access on to Lake Lucy Road be eliminated and the driveway be relocated to access Lakeway Lane. It appears the Willis property has ability to further subdivide into more than four lots. The applicant has proposed a 31 -foot wide City street and 50 -foot wide public right -of -way between Lot 1, Block 2 and Lake Lucy Estates May 17, 1995 Page 11 Lot 3, Block 3 to provide future access to the site. Lot 1, Block 2 will also be accessed from this street. ' Staff has reviewed the street grades in detail and believes further modifications are warranted to minimize tree loss, grading and the height and number of retaining walls. Staff has provided the applicant's engineer with some street grades to incorporate. Due to the short t turnaround time the current plans do not reflect staffs street grade changes. These changes should only improve the overall development by minimizing grading. These types of modifications are typically done during the construction plan review process. All lots except for Lot 1, Block 1 are proposed to access the interior streets and not Lake Lucy Road. Private driveway maintenance and access agreements will need to be incorporated into covenants to permit access to the lots adjacent to private driveways as well as the Morin parcel. ' DOCKING ISSUES ON LAKE LUCY The issue of lake access has been considered and the following options are available for ' residents. 1. No more than one dock shall be permitted on any lakeshore site. No dock shall exceed six feet in width and no dock shall exceed the greater of the following lengths; 50 feet or the minimum straight -line distance necessary to reach a water depth of 4 ' feet. 2. Intensive removal or alteration of vegetation is not allowed. Furthermore, impacts to wetlands, if any, would have to be mitigated if the altered area is over 400 square feet. 3. Land owners can share a dock b Yplacing the dock on the property line. ' 4. A beachlot can be created if the developer dedicates the land for it. 5. Any dock will have to receive City and DNR approval. PARK DEDICATION The Park and Recreation Commission reviewed this application on March 28, 1995 and recommended full park and trail fees be collected per city ordinance in lieu of land acquisition and /or trail construction. They also recommended that the existing house located on Lot 15 be exempt from these fees. If the home is demolished and a new residence is built, the site would then be subject to these fees. Lake Lucy Estates May 17, 1995 Page 12 TREE PRESERVATION /LANDSCAPING A revised development plan for Lake Lucy Estates has been submitted by the applicant. Custom grading on home sites should help preserve wooded areas on each lot. Changes have been made in the positioning of homes and streets although the total canopy coverage removal has not changed significantly. Where applicable, the applicant has attempted to move homes either closer or farther from the street in order to avoid trees. Accommodations such as this could be applied to additional lots. In Lot 2, Block 3, pulling the home a minimum of five feet closer to the road would give the ash trees in the rear at least 15 feet from the grading limits. On Lot 10 in Block 2, moving the building pads closer to the roadway would give additional distance from the grading limits to the very large oaks that exist on the lots. The same is true for the 32 inch oak on Lot 11, Block 2. Sliding the building pad to the east would ensure a reasonable amount of space between the grading limits and the tree. To assume that the shaded areas on the tree inventory denote the extent of tree loss in the development is unrealistic. Additional trees that are near the grading limits will have questionable survival possibilities. At least ten trees on the survey appear to be near enough to the grading limits that preserving them will be difficult, although they are shown as being saved. Case in point is a 30 inch Linden that will sit on a corner approximately 7 feet from a 12 foot retaining wall and 10 feet from a 10 foot retaining wall. Severance of roots that close to such a large tree can be fatal. Shifting the entrance of Lakeway Lane to the south may help the tree's odds. Twenty feet from the base to the retaining wall would give the tree the extra distance it may need to survive. Since the applicant's removal plan is somewhat ambiguous and the site is so heavily wooded, staff recommends each tree twelve inches and larger be inventoried as to species, diameter and number. The number shall correspond to the tagged numbers attached to each significant tree. The inventory will be used to develop a tree removal plan prior to construction that specifically designates all removals and saves. On a wooded site such as Lake Lucy Estates, development will always have a heavy impact. Removal of nearly half the existing canopy will not only change the appearance of the site, but the climate as well. Trees on this property have long been protected from extreme wind and sun by the dense canopy coverage and have developed in an environment with cooler soil temperatures and higher humidity than there will be after development. Due to these conditions, a plan detailing the care of trees to be preserved will be necessary. The applicant must establish a Woodland Management Plan, as requested by ordinance, outlining preservation techniques to be used and reasons for species choice and placement of required reforestation trees. This plan will be used to assess the applicant's construction process and enforced accordingly. Tree preservation fencing must be used in addition to the silt fence in Lake Lucy Estates May 17, 1995 Page 13 all wooded areas during the preliminary grading for the road. The developer shall be held responsible for all trees on site until development has been completed. Canopy coverage on the site is 7.45 acres. Removal of the canopy due to grading and construction will be 3.58 acres, leaving 3.87 acres on site. The minimum requirement of canopy coverage to maintain is 5.23 acres. The applicant exceeds the minimum by 1.36 acres and therefore must replace the loss times 1.2. The reforestation requirement for Lake Lucy Estates is 1.63 acres or 65 trees. A replacement plan incorporating the 65 trees designated for reforestation will be required. Staff recommends caliper replacement of trees lost in excess of the tree inventory plan at two times the diameter. The Landscaping and Tree Preservation requirements state that a landscape buffer is required when a subdivision plat is contiguous to a collector street. Required buffering shall include berms and landscape materials consisting of a mix of trees and shrubs and /or a tree preservation area. The plan must identify plant material locations along Lake Lucy Road as well as planting within each front yard. Appropriate financial security will be required.

Lake Lucy Estates May 17, 1995 Page 15 FINDINGS SUBDIVISION 1. The proposed subdivision is consistent with the zoning ordinance; Finding: The subdivision requires variances to meet the requirements of the RSF, Residential Single Family District. 2. The proposed subdivision is consistent with all applicable city, county and regional plans including but not limited to the city's comprehensive plan; Finding: The proposed subdivision is consistent with the comprehensive plan density designation for low density. 3. The physical characteristics of the site, including but not limited to topography, soils, vegetation, susceptibility to erosion and siltation, susceptibility to flooding, and storm water drainage are suitable for the proposed development; Finding: The proposed site has a significant tree coverage and rolling topography. The applicant will be changing the site characteristics in order to develop it. The plans can be revised to make the subdivision more suitable for this site. 4. The proposed subdivision makes adequate provision for water supply, storm drainage, sewage disposal, streets, erosion control and all other improvements required by this chapter; Finding: The proposed subdivision will be served by a public street and infrastructures contingent upon acquiring an easement through the Morin's parcel. Public sewer and water systems, storm sewers and erosion control measures are proposed in accordance with city requirements. ' 5. The proposed subdivision will not cause environmental damage; Finding: The proposed subdivision will need to be revised as discussed in the ' staff report and in the conditions of approval. Grading and tree removal must be minimized. ' 6. The proposed subdivision will not conflict with easements of record. Lake Lucy Estates May 17, 1995 Page 16 Finding: The proposed subdivision will not conflict with existing easements, but rather will expand and provide all necessary easements. 7. The proposed subdivision is not premature. A subdivision is premature if any of the following exists: a. Lack of adequate storm water drainage. b. Lack of adequate roads. C. Lack of adequate sanitary sewer systems. d. Lack of adequate off -site public improvements or support systems. Finding: The proposed subdivision will be provided with adequate public infrastructure with the extension of the sanitary sewer from the east. VARIANCE As part of this plat approval, a variance to allow 20 foot front yard setbacks, a 10 percent street grade, five homes accessing via a private street, and a 50 foot wide right -of -way is requested. The City Council may grant a variance from the regulations contained in the subdivision chapter as part of a plat approval process following a finding that all of the following conditions exist: 1. The hardship is not a mere inconvenience. 2. The hardship is caused by the particular physical surroundings, shape or topographical conditions of the land. 3. The condition of conditions upon which the request is based are unique and not generally applicable to other property. 4. The granting of a variance will not be substantially detrimental to the public welfare and is in accord with the purpose and intent of this chapter, the zoning ordinance and comprehensive plan. Finding: Staff recommends the variances be approved as shown in plans dated May 8, ' 1995, for the following: a. A 20 foot front yard setback for Lot 3, Block 1, Lot 8, Block 2, and Lot 3, ' Block 3. b. A 10 percent street grade and a 50 foot wide right -of -way C. Five homes accessing via a private drive. d. A 10 foot side yard setback for the west side of Lot 7, Block 2. Lake Lucy Estates May 17, 1995 Page 17 PRIVATE STREETS As part of this subdivision, the applicant is requesting the use of private streets to service ' portions of the site. The subdivision ordinance allows up to four lots to be served by a private street if the city finds the following conditions to exist: 1. The prevailing development pattern makes it infeasible or inappropriate to construct a public street. In making this determination, the city may consider the location of existing property lines and homes, local or geographic conditions and existence of ' wetlands. 2. After reviewing the surrounding area it is concluded that an extension of the public ' street system is not required to serve other parcels in the area, improve access, or to provide a street system consistent with the comprehensive plan. 3. The use of a private street will permit enhanced protection of wetlands and mature trees. Finding: The applicant is utilizing two private streets to access Lots 5, 6, 7, 10, and 11 Block 2 and Lot 2, Block 1. Private streets will minimize impact on the vegetation and preserve site grades. It will require 5 lots to be served via the private street, however, we believe in this case a variance is appropriate. ' PLANNING COMMISSION UPDATE: This application first appeared before the Planning Commission on April 5, 1995. Numerous issues were raised by the Planning Commission, residents, and staff. These issues included ' excessive grading, tree loss, environmental concerns, and variances. The applicant listened to the issues and attempted to address them through a revised plan. i The application was revisited by the Planning Commission on May 3, 1995. At that meeting, staff prepared a sketch plan to act as a guideline to improve the plat. The recommendation in ' the report was based on the layout prepared by staff rather than the plan prepared by the applicant. The Planning Commission unanimously agreed that the plan was not ready to be sent to City Council. Action on the application was tabled and the applicant was directed to ' modify the plans and incorporate recommendations made by staff. On May 17, 1995, the Planning Commission reviewed a plan that incorporated most of staffs recommendations. The proposal was approved with conditions. Issues that were raised at that meeting included the following: L ISSUE: The Planning Commission directed staff to advise the City Council on the appropriateness of allowing variances to the applicant on a house on Lot 7, Block 2. A second related question raised at the meeting was if the applicant would be able to create four buildable lots along the lake without a private street. FINDING: Granting a 10 foot side yard setback along the west property line will allow the house to be located away from the easterly portion of the lot which is heavily wooded. In this case a variance is appropriate. Staff believes that if a tree preservation easement outside the grading limits was granted, then a private driveway is warranted. If the applicant intends to remove the trees on Lot 7 and grade outside the grading limits, then the applicant is not entitled to a private street. ISSUE: The Planning Commission directed the applicant to work with staff regarding the appropriateness of shifting Lakeway Lane and Court to the south. FINDING: The applicant has submitted a revised plan for staffs review. The changes and staffs findings on that plan will be incorporated in the final plat staff report. ISSUE: The Planning Commission directed staff to present to the City Council a monitoring program for erosion control to ensure minor impact to the lake during construction. FINDING: The applicant will be required to use erosion control along the lake. Also, when the applicant enters into a development agreement with the city, he will have to ' Lake Lucy Estates May 17, 1995 Page 18 ISSUE: The subdivision ordinance states that if a development is proposed adjacent to a lake, or will affect the usage of the lake, the applicant shall provide the city with a list of property owners abutting the lake at the time of application. The city shall provide mailed notice to the lake homeowners as in compliance with the procedures. The ordinance also states that notice requirement and ' procedures set forth in this chapter in excess of those required by state law are directory. Failure to comply with such procedures will not invalidate the proceedings. State law requires mailings be sent to homeowners within 500 , feet. The requirement to mail notices to all property owners abutting the lake is in excess of state law requirements. Staff mailed notices to property owners within 500 feet only. Neighbors requested that a notice be sent to all property , owners adjacent to the lake. FINDING: A notice was mailed to all property owners adjacent to Lake Lucy on May 18, ' 1995. ISSUE: The Planning Commission directed staff to advise the City Council on the appropriateness of allowing variances to the applicant on a house on Lot 7, Block 2. A second related question raised at the meeting was if the applicant would be able to create four buildable lots along the lake without a private street. FINDING: Granting a 10 foot side yard setback along the west property line will allow the house to be located away from the easterly portion of the lot which is heavily wooded. In this case a variance is appropriate. Staff believes that if a tree preservation easement outside the grading limits was granted, then a private driveway is warranted. If the applicant intends to remove the trees on Lot 7 and grade outside the grading limits, then the applicant is not entitled to a private street. ISSUE: The Planning Commission directed the applicant to work with staff regarding the appropriateness of shifting Lakeway Lane and Court to the south. FINDING: The applicant has submitted a revised plan for staffs review. The changes and staffs findings on that plan will be incorporated in the final plat staff report. ISSUE: The Planning Commission directed staff to present to the City Council a monitoring program for erosion control to ensure minor impact to the lake during construction. FINDING: The applicant will be required to use erosion control along the lake. Also, when the applicant enters into a development agreement with the city, he will have to 7 11 J 7 Lake Lucy Estates May 17, 1995 Page 19 abide by the following condition: Site Erosion Control. Before the site is rough graded, and before any utility construction is commenced or building permits are issued, the erosion control plan, shall be implemented, inspected, and approved by the City. The City may impose additional erosion control requirements if they would be beneficial. All areas disturbed by the excavation and backfilling operations shall be reseeded forthwith after the completion of the work in that area. Except as otherwise provided in the erosion control plan, seed shall be certified seed to provide a temporary ground cover as rapidly as possible. All seeded areas shall be fertilized, mulched, and disc anchored as necessary for seed retention. The parties recognize that time is of the essence in controlling erosion. If the Developer does not comply with the erosion control plan and schedule of supplementary instructions received from the City, the City may take such action as it deems appropriate to control erosion at the Developer's expense. The City will endeavor to notify the Developer in advance of any proposed action, but failure of the City to do so will not affect the Developer's and City's rights or obligations hereunder. No development will be allowed and no building permits will be issued unless the plat is in full compliance with the erosion control requirements. Erosion control needs to be maintained until vegetative cover has been restored, even if construction has been completed and accepted. After the site has been stabilized to where, in the opinion of the City, there is no longer a need for erosion control, the City will authorize the removal of the erosion control, i.e. hay bales and silt fence. The Developer shall remove and dispose of the erosion control measures. The City also requires a detailed grading, drainage, and erosion control plan in conjunction with final plat consideration. ISSUE: The Planning Commission directed staff to review the impact of construction on springs on the site. FINDING: Small springs or ground water are not uncommon within the city. In the past, many farmers and developers installed drain tiles to convey and maintain the flow of water through a property. During construction, the city requires drain tiles to be maintained by rerouting them into the storm drainage systems. ISSUE: The applicant is opposed to granting a tree conservation easement on wooded areas outside the grading limits. He believes that this will limit building pads to specific locations and limit the house size. He also wants flexibility in house pad locations on the lots. FINDING: Staff discussed this issue with the applicant and informed him that we are open to alternatives that would guarantee the preservation of trees. Staff asked the applicant to submit a written proposal outlining how the tree preservation will Lake Lucy Estates May 17, 1995 Page 20 be accomplished. The applicant is working on a proposal. As to flexibility in the location of house pad outside the grading limits shown on the grading plan, there are some house pads that can be shifted around, however, all the lake lots must comply with the proposed grading plan received May 8, 1995. This is the best alternative that would minimize tree loss and grading in that area. Staff will work with the applicant to identify which lots may have the flexibility in house pad locations. This will be done prior to final plat approval.

The wetland is approximately 5.3 acres and is characterized as an inland shallow fresh marsh. ; ,Approximately 1.7 acres of the wetland is located on the property. Wetland B is the natural wetland complex that borders the Lake Lucy shoreline. The wetland is above the ordinary high water elevation for Lake Lucy, and therefore, is not within DNR jurisdiction. Approximately 1.4 acres of the wetland is located on the property. Since both of the wetlands are classified as natural, the buffer strip required shall be 10 to 30 feet wide with an average width of 20 feet. It is recommended that any disturbed areas of the buffer strip be seeded with a mixed variety of natural upland vegetation. Although these wetlands will not be filled or excavated as a result of the development, erosion control and maintenance on the erosion control is a key factor in protecting wetlands. Type III erosion control shall be provided Sharmin Al -Jaff May 10, 1995 Page 2 around the wetland at the start of construction and maintained until vegetation is fully re- established. SURFACE WATER MANAGEMENT PLAN (SWMP) The City has adopted a Surface Water Management Plan (SWMP) that serves as a tool to protect, preserve and enhance water resources. The plan identifies, from a regional perspective, the storm water quantity and quality improvements 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 the 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. The development will be required to be constructed in accordance with the City's Surface Water Management Plan. Storm Water Quality Fees The SWMP has established a water quality connection charge for each new subdivision based on land use. Dedication shall 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 market values of land in the City of Chanhassen plus a value of $2.50 per cubic yard for excavation of the pond. The City has had discussions with the applicant's engineer on the water quality ponding. The proposed SWMP water quality charge of $800 /acre for single- family residential developments may be waived if the applicant provides water quality treatment according to the City's SWMP standards. The stormwater quality pond shall be designed to retain up to 75% phosphorus according to the Walker Pondnet model. Storm Water Quantity Fees The SWMP has established a connection charge for the different land uses based on an average city -wide rate for the installation of water quantity systems. This cost includes land acquisition, proposed SWMP culverts, open channels and storm water ponding areas for runoff storage. Single family residential developments will have a connection charge of $1,980 per developable acre. The total gross area of the property is 16.34 acres; however, 4.86 acres is wetland. Therefore, the proposed development would then be responsible for 11.48 acres resulting in a water quantity connection charge of $22,730. This fee will be due payable to the City at time of final plat recording. 1 Sharmin Al -Jaff May 10, 1995 ' Page 3 I GRADING & DRAINAGE The applicant has incorporated many design changes that staff had proposed previously. Some ' of the changes include custom grading the wooded lots, increasing the street grades up to 10% to conform better with the existing ground contours which results in less grading, adjusting of building pad elevations and /or changing the dwelling types to conform with the existing ground to minimize grading, modify the street and cul -de -sac alignment to accommodate a water quality storm pond (Walker basin) for pretreatment of storm water prior to discharging into the wetlands, adjusting lot lines and building types where significant trees can be saved, combine the sanitary ' sewer alignment from Morin's property with the private street (Lakeway Court). The plans have been prepared with a 50 -foot right -of -way, again, which is less than the City's standard right -of- way in an attempt to preserve trees and lessen the amount of grading. Staff believes that this ' compromise in right -of -way width will reduce grading and minimize impacts to the site. Another alternative would be to reduce the building setbacks. ' Staff has also worked on the street grades which we believe will minimize grading, trees loss, and the amount and height of retaining walls. The applicant should incorporate street grades ' throughout to conform better with the existing terrain. Staff would be happy to work with the applicant's engineer to assure that this is accomplished. Staff also considered shifting the intersections of Lakeway Court and Lakeway Drive as well as Lakeway Lane and Lakeway Drive ' southerly by approximately 20 feet to match existing grades better and lessen the sanitary sewer depth. Lakeway Court is currently proposed with up to 7% street grades. The relocation of Lakeway Court further to the south will, however, result in the loss of an additional 14 -inch oak tree on Lot 9, Block 2 but will in return save two significant oak trees which are proposed to be lost on Lot 4, Block 1 (24 -inch and 26 -inch oaks). Lakeway Court also needs to provide for a turnaround acceptable to the City's Fire Marshal. A temporary turnaround could be created on site (Lot 2, Block 1 or Lot 11, Block 2) until the Morins further subdivide. The southerly private street (Lakeway Drive at the end of the cul -de -sac) is proposed to serve Lots 5, 6 and 7, Block 2. The applicant has revised the grading plans to limit fill to only the house pad areas and the service drive. Previously, the applicant had proposed up to 8 feet of fill in this area. Staff has reviewed this proposal and believes the applicant has minimized the ' impact to this area short of reducing the number of overall lots at the end of the cul -de -sac. In order to provide sanitary sewer service to Lots 5, 6, and 7, Block 2, up to 4 feet of fill will be required to provide adequate cover to prevent freezing. The homes in the cul -de -sac (Lots 5, 6, and 7, Block 2) have been designed to eliminate the need for an ejector pump as well. House dwelling types on Lots 6 and 7 have been revised from walkouts to lookouts to further minimize grading. Surface water runoff from Lakeway Drive will drain between Lots 5 and 6, Block 2 towards Lake ' Lucy. Staff feels there is a more than adequate buffer to pretreat the amount of runoff generated Sharmin Al -Jaff May 10, 1995 Page 4 from the additional homesites prior to discharging into Lake Lucy. The applicant has further designed the stormwater basin located on Lot 3, Block 2 which is proposed to convey and pretreat stormwater runoff from the street and front yard areas of the subdivision. This pond will then outlet underneath Lakeway Drive easterly back to the wetlands to assure recharging of the wetlands. At the Planning Commission meeting residents were concerned about the runoff being directed back into the wetland and being detrimental to wetland. Staff believes that it is necessary to route the treated stormwater runoff back to recharge the wetland. The exact location of the outlet pipe underneath Lakeway Drive is subject to change. Staff will locate in the field a path for the storm sewer to minimize impacts to the existing vegetation. This typically is done in conjunction with review of the final construction plans. Other concerns from the residents were location of numerous existing groundwater springs, storm sewer calculations, water quality, environmental impacts, erosion control measures, height of the retaining walls. The plans as submitted do not show erosion control fence; however, staff will require fencing around the perimeter of the grading limits on the final grading plans. Storm sewer calculations are typically not submitted for staff review and approval until the final construction plans are prepared. Typically with preliminary plat approval, there are numerous revision in grading and lot layouts that will change the storm sewer calculations. Staff is confident that there is adequate room being provided for the stormwater pond to pretreat the runoff prior to discharging into the wetlands in accordance with the City's SWMP. Within the City of Chanhassen groundwater is evident typically with each development. This groundwater is not necessarily springs. The City with its rolling terrains and heavy clay soils frequently contain areas of groundwater. Subdivisions typically deal with groundwater through the use of either storm sewers or draintile systems to convey the runoff to the stormwater ponds and /or wetlands to maintain the groundwater migration pattern. The applicant is proposing boulder retaining walls up to 12 feet in height along Lakeway Lane/Drive (Lot 3, Block 3). Staff believes that with revised street grades, these retaining walls can be reduce in half. This will also minimize impact to existing trees adjacent to boulder retaining walls. To preserve existing vegetation, staff is proposing the homesites on Lots 3 and 4, Block 1 and Lots 8, 9, and 10, Block 2 be built lower than the street to reduce the amount of fill required in the front yards. Typically, staff has reservations regarding placing the homesite lower than the street due to drainage concerns, however, a grading and drainage plan could be developed with each individual homesite to ensure proper drainage around the structures. A good example of this within the City is along Bighorn Drive within the Shadowmere subdivision. Staff has also further reviewed access and utility service to the "Willis parcel" west of this development. It appears the parcel may be further subdivided once sewer and water is available to the parcel. The applicant has incorporated staffs' recommendation by providing a 50 -foot ' Sharmin Al -Jaff May 10, 1995 Page 5 right -of -way ( Lakeway Lane) to extend utility and street service. The Willis parcel would be required to access this street pending further subdivision of the parcel. Drainage off Lakeway Court is proposed to drain to a low point between Lots 10 and 11, Block 2. Staff believes the road should be tilted to provide sheet drainage across the street between the house pads towards the wetlands. Most of this runoff is from backyards or lawn areas which ' requires minimal treatment. The buffer strips between the houses and the wetlands will be sufficient in pretreating runoff prior to reaching the wetlands. Typically, with the soil conditions on hilly terrains, ground water may be of concern. The City requires a drain tile system behind the curb and gutter for homes which are not adjacent to a ' wetland /pond. The drain the system provides an acceptable means of controlling sump pump discharge from the homes as well as improve the street subgrade. The building setback lines, buffer strips, and tree fencing needs to be denoted on the final grading and drainage plans prior to final plat approval. EROSION CONTROL Erosion measures and site restoration shall be developed in accordance with the City's Best Management Practice Handbook (BMPH). Staff recommends that the City's Type III erosion control fence which is a heavy duty silt fence be used around the wetlands for maximum protection. The final grading plan shall incorporate erosion control fence around the perimeter of the grading limits. In addition, tree preservation fencing should be denoted on the grading and drainage plan as well. I UTILITIES � i Municipal sanitary sewer service is proposed to be extended from the Coey parcel which was recently subdivided into Point Lake Lucy. The Coey parcel is located approximately 200 feet east of this site. The sewer line to date has not been extended to service this parcel from the Coey parcel. Sanitary sewer is proposed to be extended this spring, early summer through the Coey parcel and deadend at that the property just east of the development ( Morin's). The exact alignment of the sewer line has now been staked in the field up to the Morin's property. The alignment minimizes tree loss and impacts to the wetlands and Morin's property. The applicant has been working with the Morins to acquire the necessary utility easement for this extension in order to proceed with the project. The sanitary sewer will need to be extended through the Coey and Morin properties. Without the sewer, this project would be considered premature for development. A condition has been added in the staff report that final plat approval will be contingent upon sanitary sewer being extended through the Coey and Morin properties. The Sharmin Al -Jaff May 10, 1995 Page 6 plans have relocated the sanitary sewer line to follow Lakeway Court in an effort to minimize impacts to the existing vegetation. Municipal water service is available to the site from Lake Lucy Road. The plans propose on extending water service throughout the development. Detailed construction plans and specifications will be required in conjunction with final plat approval. The construction plans and specifications shall be prepared in accordance with the City's 1995 edition of the Standard Specifications and Detail Plates. Final construction plans and specifications will be subject to City Council approval. The applicant will be required as a part of final plat and construction plan approval to enter into a development contract and provide the City with financial securities to guarantee conditions of approval and installation of the public improvements. The development contains two existing homesites (Tichy and Christensen). Both of these homesites are currently on their own well and septic system. The existing home on the westerly portion of the site (Lot 1, Block 2 - Christensen's) is proposed to be removed. The other home (Tichy) is proposed to remain on Lot 1, Block 1. Both on -site well and septic systems will have to be abandoned in accordance with the City and State health codes in conjunction with this development. The well and septic on Lot 1, Block 2 will have to be abandoned in conjunction with site grading. The well and septic system on the Tichy property (Lot 1, Block 1) may be delayed since the construction activities appear not to impact the systems. However, city ordinance requires properties within 150 feet of a municipal sewer system must be connected to the City's system within 12 months after the system becomes operational. Connection to City water is not required until the well fails. The sanitary sewer to serve this development will be designed and constructed to service the Morin's property as well as the properties to the west and north of the site. The applicant has shown sewer and water extension west of the cul -de -sac towards the Willis property. Staff has reviewed the utility service to the Willis parcel and feel Lakeway Lane is the appropriate extension point for utility service. The sanitary sewer elevation should be at 996.0 at the end of Lakeway Lane. This can easily be changed on the plans and is typically reviewed during the final construction plan review process. STREETS Access to the development is proposed from Lake Lucy Road. This road is classified in the City's Comprehensive Plan as a collector street. Street right -of -way on the public street has been reduced from the 60 -foot requirement to 50 feet wide to reduce grading and tree loss. Staff has evaluated this compromise with the revised plans and believes the reduced right -of -way is warranted. The plans are also incorporating the use of private streets to service portions of the development and adjacent parcels. City ordinance provides up to four homes to be serviced off a private street. A turnaround acceptable to the City's Fire Marshal will also have to be provided. Sharmin Al -Jaff May 10, 1995 Page 7 The private street will reduce impacts to the wetland and tree loss versus the public street. Staff believes the use of private streets to service Lots 5, 6 and 7, Block 2 is warranted to reduce impacts to the area. The house pad on Lot 7, Block 1 has been relocated westerly as shown on staffs layout to minimize grading and tree loss. The use of a public street in this area would destroy the natural features. In addition, Lots 6 and 7, Block 2 would be marginal lots due to setback requirements from wetlands and the street. Staff believes the applicant has followed the layout prepared by staff to minimize the environmental concerns. Another private street is proposed to service three lots (Lots 10 and 11, Block 2 and Lots 2, Block 1) and the Morin's parcel to the east. The Morins and staff have reviewed the development potential of the Morin's parcel and it appears that the site may be further subdivided into two additional lots. Therefore the private street ( Lakeway Court) as proposed would be serving up to five homes which exceeds the City's ordinance. Staff believes there is no other way to create a street system to serve these lots which would minimize impacts and therefore recommends a variance be granted for up to five (5) homes accessing Lakeway Court. A turnaround which meets the City Fire Marshal's requirements will be necessary at the end of Lakeway Court. If the Morins are not in favor of the turnaround at this time, a temporary turnaround could be developed on Lot 2, Block 1 or Lot 11, Block 2 until the Morins are ready to subdivide. Future access was also considered for the parcel west of the development (Willis) which is currently for sale. The Willis parcel currently gains access from Lake Lucy Road via a long gravel driveway. Part of the driveway is actually located within the proposed subdivision and is shown through Lots 1, 2 and 3, Block 3. The Willis driveway access on to Lake Lucy Road is across from Yosemite. This intersection has substandard sight distance which makes it difficult to safely turn to and from the property. Eventually, when the Willis parcel further subdivides, staff will recommend that the driveway access on to Lake Lucy Road be eliminated and the driveway be relocated to access Lakeway Lane. It appears the Willis property has ability to further subdivide into more than four lots. The applicant has proposed a 31 -foot wide City street and 50 -foot wide public right -of -way between Lot 1, Block 2 and Lot 3, Block 3 to provide future access to the site. Lot 1, Block 2 will also be accessed from this street. Staff has reviewed the street grades in detail and believes further modifications are warranted to minimize tree loss, grading and the height and number of retaining walls. Staff has provided the applicant's engineer with some street grades to incorporate. Due to the short turnaround time the current plans do not reflect staffs street grade changes. These changes should only improve the overall development by minimizing grading. These types of modifications are typically done during the construction plan review process. ' All lots except for Lot 1, Block 1 are proposed to access the interior streets and not Lake Lucy Road. Private driveway maintenance and access agreements will need to be incorporated into covenants to permit access to the lots adjacent to private driveways as well as the Morin parcel.

It appears that recommendation #4 from my earlier memo is the only item that has been addressed, so the other comments and renumbered recommendations are repeated below. Analvsis: Elevations. Proposed lowest floor level elevations, top of foundation elevations and garage floor elevations are required in order to insure adequate plan review by the Public Safety and Engineering Departments. Dwelling Type. The proposed type of dwelling designations are necessary to enable the Inspections Division, Planning Department and Engineering Department to perform a satisfactory plan review of the structure at the time of building permit issuance. Standard designations' (FLO or`RLO R, SE, SEWO, TU, WO) must be used for proposed dwelling types. These standard designations `lessen the chance for errors during the plan review process. I -have included the 1993 memo which lists and explains these designations. Soils Report. In addition, a soils report showing details and locations of house pads and verifying suitability of natural and fill soil is required for plan review purposes. Demolition Permits. Existing structures on the property which will be demolished will require demolition permits. Proof of well abandonment must be furnished to the City and a permit for septic Sharmin Al -Jaff May 9, 1995 Page 2 system abandonment must be obtained and the septic system abandoned prior to issuance of a demolition permit. Recommendations: 1. Revise Grading and Drainage Plan to indicate lowest floor level elevation, top of foundation elevation and garage floor elevation. This should be done prior to final plat approval. 2. Revise the Grading and Drainage Plan to show standard designations for dwellings. This should be done prior to final plat approval. 3. Submit soils report to the Inspections Division. This should be done prior to issuance of any building permits. 4. Obtain demolition permits. This should be done prior to any grading on the property. enclosure: 1/29/93 Dwelling Type Designation memo g: \safety \sak \memos \plan \1klcyest.sj2 CITY OF CHANHASSEN 690 COULTER DRIVE • FO.

Mancino: Are there any questions of staff at this point? I just have one. Sharmin, the retaining walls around Lot 1, Block 2 that are on the east side. Front of that lot. They are 300 and 400 feet long. Are those the ones that are 12 feet tall at this point? Al -Jaff: Actually the 12 foot retaining wall is on Lot 3, Block 3. 1 Planning Commission Meeting - May 17 1995 an gCo g y , Mancino: Okay. Do you have any idea how tall the ones are that are around Lot 1? Are ' those fairly tall, do you know? ' Al -Jaffa It's anywhere between 4 feet and 11 feet. Mancino: Okay, thank you. Any other questions? Does the applicant wish to address the Planning Commission? Michael Byrne: Madam Chair, members of the Planning Commission. My name is Michael Byrne. I reside at 5428 Kimberly Road in Minnetonka. I first want to say thank you to staff for... especially Mr. Hempel, who has been very clear, concise and... Dave is busy welcoming his first born son tonight so he's not here to hear this. This is the third time this and as you ' stated... staffs given the recommendations to the Council. I don't wish to re -read through the staff report. It's painfully concise... worked on quite hard. I was told when we started this by commissioners, to make sure I work with staff. To be very clear. To work... Sometimes it's ' been very difficult to balance ... I want to mention first of all, there was concern about the maintaining of the area during construction and after construction of the wetlands along number 1, Lake Lucy and number 2 ... pond. I can only reiterate what the staff had indicated... ' that we'll be using the best program. In addition to that, the mulching and seeding... licensed landscaper... Part of the program will be a doubling of the ... in the drainage areas. The plans that you showed, or are looking at, does not unfortunately show a silt fence. That is an error on ... part and we apologize. But that did show on a previous... staff knows very well where it's going. We were going to be asking the staff if they wanted us to follow more closely the contour or the grading line or ... and we'll take their recommendation in whichever direction they wish us to go. The changes you've seen, both in lot lines, grades, house spots, have all been recommended to us by staff.. One of the things that you asked specifically was about the change in the boulder walls. On Wednesday, Dave Hempel did a extensive review from 1 the grades on the site and recommended to us after he had seen our plan, changing those grades. Moving them in certain areas from ... to 10% over an approximately 230 foot distance. The wall that you were referring to, were reduced approximately half of that. The movement of the entrance of Lakeway Lane and Lakeway Court southerly was an attempt to avoid certain trees on Lot 3, Block 3. We're at the point now, if we move a line 10 feet, 20 feet, we're hitting 3 trees to the south to preserve 3 trees to the north because that's how close we're balancing this. The same goes for the movement of Lakeway Court. That movement will hit 3 trees to save 3 trees. You can tell by that it's getting very finely balanced. Very ' finely tuned ... know we've achieved what the staff hopes to achieve. That is to do as much, the least amount of possible damage to the site. There was concern that one of the commissioners that staff was designing the project for us. That's a question I can't really ' answer. At what point does the staffs recommendations stop and our drawings start. The ' 2 1 Planning Commission Meeting - May 17, 1995 staff report is so intense and so accurate... and I will await to hear the other commentaries before I come back to you. If there's any questions... Mancino: Any questions from commissioners? I just have one Mike. On my sheets, what I'm seeing in front of me is, the dates on the first three are 7- 12 -94. So am I looking at the right one? In the lower right hand corner. Michael Byrne: That's when, that's the original draft possibly of just the contour lines. Mancino: Well actually you know what? This is interesting. In the lower right hand corner it has 7 -12 -94 and then on the left hand corner it has revision dates on it. 1, 2, 3, 4, I just want to make sure, could you come and look at this and make sure that this is the, I don't know. Does everyone else have the same? Farmakes: Same here. Michael Byrne: This is what you're looking at here? Mancino: Now I look down here, and here was the date. And then I looked over there. Michael Byrne: 7 -12 -94 undoubtedly was the time that the contour lines for this entire area were started. Mancino: And then the other dates are the overlays? Michael Byrne: Not all the overlays. There's been approximately 15 different variations that have been worked on. Major ones and the ones that have been submitted to the city are the only ones probably here. Mancino: Okay, I understand now. Thank you. Michael Byrne: Do you have any other questions at this point? Mancino: Thank you. May I have a motion to open the public hearing? Meyer moved, Far-makes seconded to open the public healing. All voted in favor- and the motion carried. The public healing was opened. Mancino: Okay, this is open for a public hearing. Those who wish to address the Planning Commission, please come up. State your name and address. 3 C u n I Planning Commission Meeting - May 17, 1995 Al Weingart: Good evening. My name is Al Weingart. I think you've seen me before and you're probably getting tired of seeing me up here but appreciate the opportunity to speak before you again. I live at 5330 St. Albans Bay Road in Shorewood and I am the current owner of the Lake Lucy peninsula and soon to be buying... Steller Court. I'm not going to take up a lot of time here with what we've already talked about in prior Planning Commission meetings as well as, you have voluminous amount of materials we've provided you. If you'd put up my slide too. My slide on, I want to only put this up there for the purpose of reiterating again that our group is fairly serious about what we're doing here. We tend to continue to be so. I'm not going to go through all this but basically we have been all over this project from day one as far as trying to impress upon not only the applicant, Mr. Byrne, but also upon staff as well as upon you and we've met with many of you. We've had you out there. We've had the Mayor. I've spoken to the Mayor and a few City Council people about what's going on here so everybody seems to be fairly well informed and hopefully have receive copies of most of this stuff, but if anybody has any question about it, you certainly can ask for copies. So but the effect on us is primarily aesthetically, environmentally and economically. Those three things we feel we are somewhat at risk with respect to this project. Continuing examples of why we feel we're at risk, or not at risk but at least be influenced by. Being at risk might be a little bit strong but influenced by it, is basically one example, and this is the only example I'm going to put up relative to what we talked about before, and that is essentially the tree canopy calculations. The point here is not to show the fact that we're taking down more trees than we were the last time we talked about this issue, but primarily to emphasize the fact that they're taking 2/3 of the trees on the whole site and if that's not abusive, then I guess I would find a hard time understanding what might be. So I guess we're trying to impress upon you the impact this is going to have, not only on the properties that the developer's trying to develop here but also our own properties that surround this property. And the financial impact as well the aesthetic impact and the environmental impact to that whole area. The sensitivity that it has to Lake Lucy and the wetlands that support a group of wildlife around there and also the aesthetic nature of the property. So that's the point of showing you this that 66% of that environment, at least the tree cover, is going to be taken away. And what we're asking you to do tonight is basically to deny this application and send it onto City Council. The reasons for the denial can be a number of them from the standpoint of you don't really have a preliminary plat, like I talked about last time. I think that's arguable and you probably won't agree with me on that but there still are certain provisions in the city ordinance that would not qualify this as being a full preliminary plat. There's still a lot of drawings that have to be done on this, from what Sharmin was telling us and so that would be one argument I guess. The variances, in my opinion anyway, are a privilege and not a right and the applicant makes the argument that he has been through a lot of reiterations on this. However, basically it comes down to the fact that we've gone from mass grading to something that 66% which is going away. So if that's an improvement, then I'm missing something. Another one would be the detrimental impact to the wetlands 4 1 Planning Commission Meeting - May 17, 1995 from the runoff of the water into the wetlands, not into Lake Lucy. I know on my property when it went before you and the City Council, there were a number of provisions put in there to restrict what I could do on my property relative to runoff, etc. One of them being that I cannot put salt on my driveway in any way because it would leech into the lake. We have 10% grades here. That water's going to run right into the lake and into the wetlands. That would be something maybe you ought to consider to think about relative to the property like this. That it's particularly... graded severely. And if nothing else, basically this is the kind of development that is just not good public policy period and that's a very broad argument, I understand but it's just one of those developments that, it could be done a lot better. It could be done economically for the developer. Which we realize it's got very excellent piece of property there that he can get high dollar for if he would just take some of the recommendations of people who have tried to offer them to him who know something about the economics. And that's all I'm really going to say now. Just that we'd appreciate a consideration of denial and let City Council deal with this at this point. Thank you. Are there any questions? Thank you. Mancino: Thank you. Anyone else? Joe Morin: Madam Chairman, members of the Planning Commission. My name is Joe Morin. I live at 1441 Lake Lucy Road, Chanhassen. We have the property immediately to the east of the proposed development. First of all I want to thank the staff very much for their tremendous efforts. The diligence that they've put in. I truly appreciate the work they've done in trying to preserve the environment, in a sense with one hand tied behind the back, since they were operating under the constraint of working within a number of lots that Mr. Byrne had originally proposed. Even under that constraint they've made ... to the existing plan. If it wasn't for their efforts, we would still be looking at mass grading on 95% of the site. And as Al points out, now we're losing only 66% but that's still a significant change. I think credit for the progress that's been done to this point is due strictly to the staff. I'm disappointed that the developer has shown any creativity in taking their recommendations and extending that even further. ...value the property and the amenities certainly could be realized with a lot fewer lots there. Progress has been made but I don't believe that sufficient progress has yet been made. I don't want to take up a lot of your time tonight repeating the points I've already made but I do want to tick off a few major items. I still believe that there's still excessive density for this site. It's not compatible with the development going on on the east property line. The Mason Homes development. There are still 11 variances on 8 of the lots, although staff is requiring that most of these be eliminated. The springs on the property has still not been identified or located or even addressed by the applicant. Last Friday Eric Rivkin and I met up with our children and he showed me the springs. One of the springs running right out of the ground. It's in the area of Lot 6, which is probably in the buffer zone. It may not impact the development but still, the deer and the other wildlife within that I 1 U Planning Commission Meeting - May 17, 1995 area ... water, at least one of the conditions ought to be to put a fence around it to protect it from the bulldozers and from the fill. There's still 4 to 5 feet, perhaps more by the lake. You still have the impact of the fill on the pond and the lake. The impact of big houses in the middle of a wildlife migration zone. We still have 15, 16, 17,000 square .foot lots on steep, heavily wooded terrain. 12 foot high retaining walls. 300 feet long walls, maybe 4 to 11 feet high in places. I'm not sure if shifting it south is going to affect all of these or not. Some, they probably can be reduced somewhat but it's some of the staffs recommendations. There's still excessive tree loss. It's even worst than what Al described. If you read the front page of the staff report. The staff notes that at least 10 trees on the survey appear to be near enough to the grading limits that preserving them will be difficult, although they are being shown as being saved. These are 150 year old trees. They're irreplaceable. There's still an impact on the wildlife. The applicant hasn't even talked about this. I think that this development still is abusive to the environment. I want to make just two more points. There's still too many lots in the southern region of the development and I want to focus on this for just a moment. What the overhead here shows is the no variance plan. The plan that the applicant was asked to put together showing what could be done if no variances were allowed. I put this up during our last meeting but I want to highlight that there's no access to that top lot, which is shown in there. There's no access so that is not buildable. The dashed line that you see is the 50 foot buffer zone. He cannot, the homes must be pushed back from that 50 foot buffer zone. The point I'm making is that in that southern area the applicant can only access 3 lots. He cannot get 4 homes down there without a private street. Now per city ordinance, use of a private street can be allowed if the use of a private street will permit enhanced protection of wetlands and mature trees. Now clearly the applicant is using a private drive in this area simply to gain an additional lot at the expense of the natural environment. So my final two points are these. Number one, staff is recommending approval with conditions. Now if approval with conditions is granted, we request that the additional condition be added that Lot 6 be eliminated. Point number 2, my final point is however we believe that the ordinance about preserving and protecting the natural amenities such as vegetation, wetlands, steep slopes and water courses is being violated with this proposed plan. On that basis we request that this application be denied. Thank you. Mancino: Anyone else like to address the Planning Commission? Michael Byrne: Madam Chair. On the point ... he's using the figure which ... the tree removal process Mr. Thornton has... calculation. The ordinance lays out a replacement program which calls for 1.2... Our own covenant restrictions exceed those by 50 %... Mr. Weingart also made a note that water rushing down a 10 foot ... flow immediately into Lake Lucy. I believe he's forgetting about the ... pond. He indicates that this site will be detrimental and environmentally ... Mr. Morin brings up the fundamental cry that the site would be better with bigger lots and more expensive... As I asked Mr. Morin... because Mason Homes is aware of Planning Commission Meeting - May 17, 1995 the economics ... it doesn't work that way. We're trying to use very attractive sites to create very attractive homesites for... custom homes. — creating $250,000.00 lots on this site is not even reasonable or ... statements made over the last 3 meetings have had... melodrama. Normally at this point in time I would have asked Dave Hempel to identify within the staff report, which I believe he would have argued that Mr. Hempel has answered continually some of these questions about, number one. Some of the requirements for example ... they have been done. Mr. Hempel has indicated because of the changes that are going to be continuing to make... final plat, those calculations he would accept ... We've done our necessary preliminary... The soils examinations are done before the final plat. Mr. Hempel in the staff report has continually brought that up. I can only depend on what staff.. In conclusion, I'm asking for approval... your job has always been and remains the same. To evaluate the staffs efforts and recommendations. The presentations ... to make your decision. I think we've done the best that we can in this situation with the limitations that we have ... thank you for your time. Mancino: Thank you. Do we have a motion to close the public hearing? Oh excuse me, one more. Joe Morin: Would it be okay if I just... Mancino: Joe, would you come on up and state your name and address again. Joe Morin: My name's Joe Morin, 1441 Lake Lucy Road. The only thing I wanted to address is, as you can see there are several homes immediately adjacent to the pond and also immediately adjacent to the lake. Runoff from those homes runs directly into Lake Lucy. The storm sewer... Secondly, Mike, Mr. Byrne eluded to the Mason Home density. If we were to apply the same density calculations to the development on the west, there would be 4 to 6 new homes in that area. Now obviously this plan is much more environmentally sensitive than is the site that Mason Homes is developing so one would expect even a greater degree of care and diligence and sensitivity to the environment. We're not seeing it here. I'm trying not to be ... but there's value in this property that extends beyond the economic value and there is in fact economic value that could be traded here above and beyond what will be traded when the environment is destroyed. That's all I want to say right now. Thanks. Mancino: Thank you. May I have a motion to close the public hearing. Skubic moved, Fwmakes seconded to close the public healing. All voted in favor and the motion carried. The public healing was closed. Mancino: Comments from the commissioners. Questions and comments. Jeff. 7 Planning Commission Meeting - May 17, 1995 Farmakes: I'm not going to make any comments on this. Mancino: Bob. Skubic: This is a particularly difficult development for me. I'm relatively new at this and I've had the benefit of looking at it from developments that have been completed and I look at this development for. Audience: Louder please. Skubic: I've had the opportunity to look at completed developments and now I get the chance to look at development before completion but I haven't had the benefit of seeing a development before and afterwards so I'm a little hard pressed to make a good judgment on this one but. There are a number of variances on this development. In my short experience here I have not had a proposal, seen a proposal that was this difficult and required as many variances as this. There is certainly justification for that. It is difficult grades to work with. We have the lakefront and so forth but I get the sense that this is like putting a square peg in a round hole. It just isn't right. That's all. Mancino: Ladd. Conrad: Well we've seen this 3 times. I think staff had a chance to look at it 3 times and work with it every day. Issues the neighbors bring up we have ordinances for. There's a couple that we don't. Staffs job is to interpret the ordinances and my cut at it is they have done that. Unfortunately, when you have a sensitive area, there's not an ordinance for that and it's tough to develop one. We don't have one. I think the staff report is appropriate. Staff is interpreting the ordinances as they are and interpreting them fairly. It's probably not my druthers to develop the site this way but I think again our job is to make sure that staff is interpreting these properly. There are some variances and I think we don't have to grant them but I think the variances do create a better project. There are probably 4 points if we approve this that I would want to have incorporated into a motion. One of them would be for the applicant to work with the staff in terms of shifting Lakeway Lane and Court to the south. See if there is value in doing that. A real issue for me is the lake. And the sensitivity of that lake to this development and there is just no way you can prevent the lake from being contaminated by the development but I guess I'd like to put some kind of a monitoring, a special monitoring. I'm never sure what occurs out of the city for projects like this in terms of monitoring to make sure our ordinances are enforced and this probably deserves some special note and some special attention so I think we need that kind of review and that's not to say we distrust what's going on but I think just because you have other contractors involved, we should have maybe special review of what's going on. An issue that was not 8 Planning Commission Meeting - May 17, 1995 addressed by the engineer is the impact on the springs. I think that deserves an engineering comment by the time it gets to City Council. And then I think I'd like to have staff advise the Council on the appropriateness of developing Lot 7. Those are my comments. Mancino: Mike. Meyer: I think Ladd really hit all of my points so no comments at this time. Mancino: Okay. I would like to add to Ladd's, the appropriateness of developing Lot 7. Also, can you hear me now? Audience: No. Mancino: Can you hear me now? To also look at the appropriateness of that private, getting a variance to Lakeway Drive. Whether that should be and meet the ordinance of a private drive and why we're allowing a private drive there. A private road versus not on Lakeway Drive. Al -Jaff: Do you want me to address? Mancino: Yes, please. Al -Jaff: The applicant showed us a plan with zero variances. It is possible to serve those lots with a full fledged street. There is one lot that is questionable along the lake. Mancino: I think it would be worth it to show the differences to the Council. Al -Jaff: Okay, we can do that. Mancino: And have them look at that. Al -Jaff: It would basically preserve trees. Additional trees if we served it via a private street versus a full fledged street. But again, as mentioned earlier, one of the lots is questionable as to whether it could remain or not. Mancino: Okay. Sharmin, and just a few little questions. Lakeway Drive and Lakeway Court, is that enough of a difference in names and Lakeway Lane, for the Fire Marshal? Al -Jaff: He was comfortable with it. I brought it to his attention. E ' Planning ommission Meeting - May 17 1995 $ g Y Mancino: Okay, thank you. Couple other questions that I have, have to do with the proposed alignment of the city sewer and water to the Willis property, where it's located. Can that be moved so that it aligns itself with Lakeway Lane and doesn't create another pathway or ' swath? Al -Jaff: In the grading section of the staff report, it is recommended that the utilities be moved so that they align with Lakeway Lane. But the condition didn't make it to, or the request didn't make it to the conditions of approval. We will work with the applicant on realigning that. Another thing that I might mention is, where the utilities are proposed are ' also at the same area where the retention pond is proposed to be located. So that area is going to be disturbed regardless. ' Mancino: Oh, okay. So then... And can we also add in our conditions something about the existing driveway easement for the Willis property to remain an easement? Al -Jaff: Okay. Mancino: Until it is developed and then it will get it's access from Lakeway Lane. Is there ' also in the recommendation Sharmin, about Lakeway Court and what happens to the turn around when it, where it is next to the Morin property. What happens? Is the turn around within the, on the eastern side. Al -Jaff: What staff is recommending, the applicant provides a temporary turn around on Lot 2, Block 1 and Lot 11, Block 2. However, if the Morin's want to grant an easement at this time to provide the turn around, staff would advise it. Rather than creating a turn around now and then in the future and when they develop their property it would be vacated on this plat and then re- created again on the adjacent. Mancino: And is that stated such in the recommendation 31? Al -Jaff: Actually it's condition number 25 and it's the last sentence. It says a temporary turn around may be permitted on Lot 2, Block 1 or Lot 14, Block 2 until the Morin's parcel further ' subdivides. It's a private matter whether the Morin's wish to grant an easement at this point. Again, staff would recommend that they do. ' Joe Morin: Madam Chair, would you like us to respond? Mancino: No. I'll wait and let you do that with staff. Thank you Joe. On recommendation ' number 4. 10 11 Planning Commission Meeting - May 17, 1995 Al -Jaff: Number 4? Mancino: Yes, about the snow fence. I would like it to be very clear that I think the snow fence should be placed and inspected and approved by staff along the edge of the tree preservation easement prior to grading. So that it's all set up. It's inspected. It's approved before any machinery gets on there and starts grading. Secondly, I'd like to make sure we are granting numerous variances on this. Almost like a PUD. I'd like to make sure that we do have conservation easements on all areas outside the grading limits. And that the reason for the conservation easements is that they are to be maintained as natural woodlands. That's what's there. That means that the dead fall stays. That means that it keeps it's natural habitat for the wildlife. And it's also stated very much in our tree preservation ordinance that we talked about it and the task force, each member that not only did we want the bigger trees saved, but we were looking ahead to the future. To the future of the next generations that will be here and need those saplings and that underbrush saved too. So that we have a next generation of trees. Those are all my comments. May I have a motion? Conrad: Sure. Madam Chairman, you did make a note of the alignment of the sewer. Was that still an applicable or appropriate? Mancino: I will let staff and the applicant decide that. Conrad: Okay, so that one's eliminated. Madam Chair again, you were talking about an existing, you wanted an existing driveway for the Willis property to remain an easement. Is that what your wording was? Mancino: Yes. Conrad: Until when? Mancino: Until that property develops. Conrad: How come? Mancino: Because at the time that property develops and subdivides, it will gain it's access from Lakeway Lane. They want to, staffs position from reading the report and please correct me if I'm misinterpreting it, is when the Willis property does subdivide, that the entrance off of Lake Lucy Road is a substandard site view? Al -Jaff: Correct. 11 1 1 1 C Planning Commission Meeting - May 17, 1995 Mancino: And that you would prefer. Al -Jaff: That at the time of the Willis property subdividing, and adding more traffic onto Lake Lucy, then it would be required to utilize Lakeway Lane. I would also request that, that came from Jill Willis and the applicant was working with her and last, to my knowledge, agreed to allow. Michael Byrne: Sharmin, our intention is to agree to a temporary driveway. At such time as the ... or the subsequent owner of that property... Al -Jaff: Okay. So everybody has agreed to permit this driveway to continue until such time when it's subdivided. Conrad: Is it worthwhile getting it into the motion? Al -Jaff: Sure. While this was being discussed I wrote something so if you want me to. Conrad: See what I do. Okay. I'll make a motion. Planning Commission recommends approval of Rezoning 14.53 acres of property zoned RR, Rural Residential to RSF, Residential Single Family (95 -1 REZ), Preliminary Plat #95 -3 SUB, to subdivide 14.53 acres into 18 single family lots and two outlots with variances, (a 20 foot front -yard setback for Lot 3, Block 1, Lot 8, Block 2, and Lot 3, Block 3, a 10% street grade and a 50 foot wide right - of-way, five (5) homes accessing via a private street, and a 10 foot side yard setback for the west side of Lot 7, Block 2), Lake Lucy Estates, as shown in the plans dated April 25th. Are we sure? Al -Jaff: May 8th. I'm sorry. Conrad: May 8, 1995, with the conditions listed in the staff report with the following additions. Point 32. The applicant will work with the staff regarding the appropriateness of shifting of Lakeway Lane and Court to the south. Condition 33. Staff is to present to the City Council with a monitoring program for erosion control to insure minor impact to the lake during construction. Point number 34. Staff to review the impact of the springs by construction and report to the City Council. Point number 35. Staff to advise City Council on the appropriateness of allowing variances to applicant on house on Lot 7. Point number 36. That the existing driveway of the Willis property to remain an easement until the property is developed. Point number 37. That the conservation easement should be encouraged on all areas outside of the grading limits as presented by the applicant. And then a minor revision to point number 4 in the staff report that says a snow fence shall be placed 12 Planning Commission Meeting - May 17, 1995 and inspect and approved by staff along the edge of the tree preservation easements prior to the grading. Mancino: Do I hear a second? Meyer: Second. Mancino: Any discussion?

Mancino: Are there any questions of staff? Meyer: Sharmin, the conditions as they are outlined here, do they correspond to your plan? Al -Jaff: Mainly yes, they do. Meyer: So what this is translating into is what you have laid out here? 1 ' Al -Jaff: Correct. There are a few conditions that address the applicant's plan; however, what we are trying to achieve here is to incorporate staffs plan because is significantly reduces ' grading on the site. There are details that need to be worked out. Meyer: OK. Mancino: I have a couple questions. Can you talk a little bit about the entry into the western property, how that changes? And the retaining walls that I saw on the preliminary plat from ' the applicant? And is there a difference between what staff proposed versus that one? Al -Jaff: The difference between the property to the east and the property to the west is the property to the east actually had a surveyor go out there, look at potential sites that could be located on their parcel and we know exactly how many homesites they could get. ' Mancino: OK. ' Al -Jaff: We have not been able to get that from the applicant to the west. The more staff looked at the Willis property, the more we believed that you could get maybe more than four homes on the site. If we allowed a private drive to access the Willis property which is what ' was shown previously on the previous plat, that would have limited the number of homes to four unless the City grants a variance. We didn't want to put ourselves in that predicament; therefore, what we are recommending is a 50 -foot right -of -way through the Willis property ' that would service the entire site now. The Willis property will continue to gain access off of Lake Lucy until such time when she decides to subdivide. ' Mancino: And you want to close that access off of Lake Lucy when the Willis property is subdivided? Because I go down Lake Lucy quite a bit and there is no other way to access the Willis property because isn't, it doesn't go, its a wetland or, I'm not sure what it is on ' that... Al -Jaff: It is a wetland... ' Mancino: Through the whole length of that property that abuts Lake Lucy, is that correct? ' Hempel: The driveway basically follows the ridge line that bisects the parcel... further review after you extend sewer and water to the parcel... Staff felt that right now we have to ... 4.5 on tape ... Mancino: Would there be significant retaining walls with this... ' Hempel: There would be retaining walls at the intersection of the public street there as proposed on the grading plans where you can see ... 5.5 on the tape ' Mancino: Sure. ' Hempel: I would like to just touch on one other point... about private driveways. You may recall the previous submittal, the initial submittal, showed the private driveway going off to the east of the Morin's property similar to what is seen here in staffs layout. ...there is two groups of significant trees right in the area where the private driveway comes out on the public street. In this proposal, as with the other ones, it is kind of a trade -off. Do we lose one group of trees and save the other group or vice versa? Looking at this scenario I felt that this would allow the sewer lines also to go under the private driveway... While the value of saving trees is about equal in both scenarios, but this had greater benefit because it had run the utility lines through the rear yards... Mancino: Aren't you on more level ground, too? Hempel: You're following the grade of the hillside versus going up the hill. Mancino: With a 3% to 7% difference in grade. I just have one more question and that is Lots 9 and 10 again on the applicant's plat were walkouts. Now that has changed to lookouts. Does that mean that it requires less fill in that area because it is a lookout versus a walkout? Hempel: Yes, about a foot or two less fill in that area. The only other concern we had was the sanitary sewer elevation is very shallow and in a lookout -type home the lower level... Mancino: Any other questions of staff? Nutting: Sharmin, I guess, just to help me kind of bring things together. The applicant has submitted a revised plan attempting to incorporate various changes that came through staff and the Planning Commission at the initial meeting. Staff has concluded that there are good efforts towards obtaining the goals but haven't quite met the spirit and so staff has come up with an alternate layout. Is it the assumption that the developer has embraced staffs plan? Al -Jaff: We'll let the applicant answer that. Dave met with the applicant this afternoon briefly around 5:00 today and he agreed to incorporate some of the suggestions that we had; however, there were others that he didn't believe they would work out, so... Nutting: So the applicant is not putting forth this plan for approval. Staff is putting forth this plan for approval. OR Meyer: Sharmin, could you clarify that street grade of 10 %, is that Lakeway Drive from the cul -de -sac? Al -Jaff: Correct. Meyer: Do I understand correctly that you said there are only three lots that require a 20 -foot front yard setback? Al -Jaff: We haven't worked out the details. The plans that staff put together need to be fine - tuned and we believe the applicant should be doing that. From the layout that was put together, yes, we believe only two or three of the units will require a variance, a front -yard setback variance and not ten. 3 Meyer: OK. Thank you. ' Mancino: Thank you. Does the applicant wish to address the Planning Commission? Michael Byrne: Madam Chair, members of the Planning Commission, my name is Michael Byrne and I reside at 5428 Kimberly Road in Minnetonka. Could not hear tape at this point. The question was asked, "Does the developer approve of staffs ... your last location on ... The cul -de -sac going north ... from staff in that area. As a matter of fact, the southerly alignment of ' Lakeway Court was a part of our proposal at one time or another. They have implied there was a decision that we had to work with staff ...Tape was not clear. If you look at your copies of the plan, the grading plan and ... tape was not clear. Mark Gronberg conducted the ' redesign... If you will note ... we submitted 14... If you will note on version 14 Mark accomplished the process of rearranging the lot line to grade. The three -level road was the major reason for the improvement working from tree loss, major tree loss... Subsequently, with the reshowing of the grading lines... Mr. Gronberg, as you will note on your grading plan, tried to design a 30 -foot northerly as recommended at that time to avoid alot of trees. Obviously, with the straight line road we're going to lose some trees. Another question was ' asked if the staff designed the project. No, staff does not design the project. They have taken at least 13 different versions and is trying to take the best of each to accomplish their goals and maintain as much tree coverage as you can. I have to bring this conversation to a real sharp point right away. Both the staffs goals and ours are quite similar in the sense that you are trying to save as much trees as you can and still maintain financial... We're working and will work... There is a concept plan in the sense that I am going to develop the site to be ' sold to builders who build with custom homes. Families that wish to have their homes in the woods. That's why I purchased the site. Once you are in the woods you are going to cut trees down but the concept of being in the woods also includes having trees behind the house, in front of the house, and on the sides of the house, ideally. As I spoke with Mr. Conrad, your ordinances are not really designed for that purpose. The new ordinance, for example, six months ago calls for tree conservation. As staff tries to make this tree conservation easement as large as possible, this tends to move the house toward the street and create a little townhome and that's not what I'm trying to do. The process we are going through is to find a ' balance of what I hope to be in the woods and the staffs focusing to create as large a tree conservation easement as possible. I think we are able to work with that. I haven't seen anything yet that tells me otherwise. I have one question and brings up my point very clearly. If you look at your color diagrams, there is two of them, one showing the grading on the lake. If you look at the first one which is Lake Lucy Estates you will note the building pads are as far apart as we could get them. The easterly one is as far east as we can get it ' and the westerly one is as far west as we can get it. Lot 8 had to an approximately 180 -foot area where you can move the house back and forth to balance. That was done for two reasons. Number one, the neighbors had indicated that they wished to see less intense use of ' their shorelines. These are going to be large homes. There's no question about that. Building pads of 80 feet to 85 feet by 50 are not going to be uncommon. With staffs proposal, which is the second one, you'll see two building pads approximately 20 feet apart. While it does in fact save some of the tree plantings, we've got 7 over lots that are deep in the... Their pads are totally surrounded. That's what we're trying to do is we're trying to put house pads in trees. It irritates people, some, it irritates the neighbors. I can understand that, but what we are trying to do is create in the woods a process here with... putting two vaulted homes 20 feet apart, I don't think it will detract. It will create a mass on the... I could only ask that you look at provision 27... I'm asking you confirm... Two reports that are on ... tape was not clear at this point... That's the other part of ... As we work with custom homeowners, these are the people that are going to try to place their home in the site given the limitations of sideyard, frontyard and rearyard, etc. We try to reinforce with them saving the best of the site. The tree can't be... We wish to do those after we sit down with staff... each individual lot. We've done this before and its not... If you read the entire package you will notice the difference on lot widths. I believe that's page 3. Staff has ... tape was not clear at this point... I placed Exhibit A in there. There was some question in the staff report about the sewer easement... I would welcome any questions from you now. Mancino: Excuse me. Mike, I just have a question. This was prepared yesterday for us? Michael Byrne: Yes. Mancino: I appreciate it. Michael Byrne: We received staffs revision on Friday... Mancino: Are there any questions for Mr. Byrnes? Thank you. Can I have a motion to open the public hearing? moved, Mancino seconded to open the public hearing. All voted in favor and the motion caned. The public hearing was opened. Mancino: This is open for a public hearing. Anyone who would like to come up and address the Planning Commission may. Alan Weingart: Madam Chair. Commissioners. My name is Alan Weingart and I own the peninsula on Lake Lucy and will be buying 1695 Steller Court in September and currently reside at 5330 St. Albans Bay Road in Shorewood and we have a group of us here tonight that have obviously some strong feelings about what's being proposed. Did everyone of you get a copy of Eric Rivkin's letter that he faxed to you yesterday or today? I just wanted to be sure that you received it from him and, if not, let us know and we will get you a copy. We've chosen someone to speak to some of the things that are in there. I guess I have a, I question I have is what was just given to you? Is something new? Al -Jaffa I haven't seen it. I don't know. Mancino: This is what Mike delivered to our homes. Alan Weingart: OK. So you have not seen that? Mancino: Staff has not seen it. Alan Weingart: Well, we're sort of segregating the various things that we want to talk about here tonight amongst a few of us and I probably have the most tedious and boring aspect of 5 this to talk about because as Mike was saying, he started to quote ordinances and basically it sounded like we have a case of martyrdom here where the ordinances are forcing him to tear down trees and make small lots. What he's getting to is a situation where we have to look at this thing on a very technical ordinance basis and technical analysis of what the ordinances will allow or won't allow and it is unfortunate that we have been pushed to the situation where everything is coming down to what are technicalities of the ordinance. Usually, it is my understanding the process between Planning Commission, staff, residents and applicant is typically one of give and take and we haven't seen a whole lot of give and take in this particular situation. So, if the applicant in this case wishes to push things to the technical aspects of what the ordinance says or doesn't say, then 1 guess I would like to look at what those technical rights, or what the technical obligations are under the ordinance relative to what you guys have received and kind of go through this. It sounds like Mike is seeking to have his application approved subject to the conditions that are laid out in the staff report except for lots along the lake and we're asking for it to be tabled because, from an ordinance standpoint, we don't think that what you have in front of you right now constitutes what the ordinance calls a preliminary plat. The ordinance basically says that the Planning Commission is to make a recommendation on the preliminary plat which assumes that the preliminary plat is in existence, that there is one and right now, based upon various conditions in the staff report, it doesn't appear to us that there is any kind of preliminary plat on this to make a recommendation and, therefore, I think the applicant deserves the opportunity to go back and incorporate the various comments that staff has made, also hopefully some of them that we have made and that you will make and come back with a plat, a preliminary plat that qualifies underneath the technical provisions of the ordinance so that you guys can have something to recommend, approve, deny, or whatever and you have ample time to do that. To support that intention I guess is... I'd like to have Sharmin put this up on the overhead. I have copies of this too that I can give to you. This basically, uh, oh boy. Do you want copies? Let me get you copies. Basically what we're saying here is that you don't have a preliminary plat. Therefore, we can't really make a decision one way or another. That's our contention, anyway. The reason that we can't because basically the various things I have listed here, No. I - Lot dimensions and revised layout. Well, Sharmin mentioned that she doesn't have the lot dimensions and revised layout because it hasn't been drawn yet. She has a sketch of what it would, should look like and according to the technical verse of the ordinance you got to have a plat that has lot dimensions and revised layout. You have to show location and width of right -of -way to the Willis property and Lakeway Court. It doesn't appear that we have that now. We have a private drive as opposed to a 50 -foot street. Not to bore you with all these but basically the name of Outlot A isn't mentioned. I mean, we're talking technicalities here and if that's the game that's going to be played, that's the game unfortunately we have to play. Accurate soil reports, compliance with minimum setbacks on revised plan... There is no revised grading plan because of the grades that are coming off of Lakeway Court. We don't know what that looks like and how the sewer goes underneath it or not. We just don't know that. The reforestation plan, I'll get to that in a minute and, of course, the replatting with the, and the reassessment of the requested variances. We don't know how those variances are going to be impacted on the property because we haven't seen a drawing of what the impact of that is. So these are the kinds of things that we don't think we have complete preliminary plat similar to the ordinance. Therefore, I don't think we can make a decision to approve something that we don't have enough information about. Now what Sharmin is saying is it's merely a matter of degree, too. There are conditions that can C.1 be approved if you in fact have a preliminary plat. But what we have here, in my opinion, are a lot of requirements that are not met. There is a difference between conditions and requirements and that is the distinction I think is important in this particular case. Changed tape at this point. Alan Weingart: ...is the tree canopy and we don't have a reforestation plan. Mike even admitted that he doesn't know what kind of trees are going to be taken down and there's no way to know without having a new plan drawn relative to reforestation. In this particular case based upon the staff reports, there's a total acreage of 14.5 acres plus the wetlands gives us the buildable acreage and roads and the canopy ordinance requires % maintained to b n be be allowing 5.2 acres in this case. The required canopy to reduced by what staff feels is the applicant's additional canopy that he is going to remove... So now we're down to the canopy that's being? acres m ainta i ne d d trees4 Now I don'tlknowbu�ldu buildable acres. Therefore, he is removing a little over st sounds a bit unreasonable. Maybe the applicant should take a look at the site and figure out that, it doesn't take alot to figure out, that maybe this isn't the kind of site to put that much density of ... homes into having to remove obvious even the note at the botto Just frustrates me I guess because it Just seems where they indicated in the staff report that "realistically, more trees may ultimately be removed than is shown on the grading and tree inventory survey ". So, I think 62% is probably the minimum here and its... from there. Anyway, if any of you have any questions on the technical aspects of this stuff I would be happy to attempt to address them. This may not be the case but we have plenty of time between now and May 17 to discuss whether or not these various things are being to allow the appl gto met and I come back with plans that, Commission has asked for t in our opinion, constitute a preliminary plat and also give us time to respond to those. Maybe not through a public hearing but through correspondence and I think that's only fair to both sides to do that. So, any questions for me? OK. Mancino: Thank you. Anyone else? Joe Morin: Madam Chair, members of the Planning Commission. My name is Joe Morin and I live at 1441 Lake Lucy Road. I own the parcel immediately to the west of the, to the east of the proposed development taking place. At the last hearing of this proposal the proposal was so far off that the applicant did not make an attempt to present it for consideration and during that discussion Mr. Conrad detailed 5 major points which were not adequately addressed by the applicant's initial submittal. These were the water quality pond, sensitivity to the physical characteristics of the site, storm damage, environmental damage and variances. Nancy Mancino cited ordinances about preserving and protecting natural amenities on the site such as vegetation, wetlands, steep slopes, water courses and other members of the Planning Commission were in agreement that these issues were not adequately addressed. What I want to do tonight is to kind of outline or use Mr. Conrad's 5 major points as a guide to quickly highlight as many specific areas as I can where these concerns are still not adequately addressed. The first area, water quality pond. This is an improvement to what was originally submitted since there is a water quality pond; however, there are numerous springs that Eric Rivkin spoke of at his last meeting that are in this general location pretty 7 Ll 1 r,, 1 n close to where this water quality pond is being proposed. All I can say is pretty close because Eric spoke of them as bubbling out of ground when he was cross - country skiing through there and he spoke of them as being right in this general area near Lot 6 and near the area where the proposed pond is going in. These springs have not been located, they have not been identified and they have not even been addressed at all by the applicant and I don't what impact to put in a holding pond near a natural spring is going to have or, for that matter, trying to install a building pad. So I think that is something that is significantly missing. The second item related to the water quality pond is a matter of personal interest to me. I need to understand... staff has managed to take this time to speak to many of us and members of the Planning Commission which also have this concern but the ponding area is located to the west of the proposed road but there's a pipe going under the road back into the existing pond on the site and the overflow water from the holding pond is being dumped into the larger or bigger pond which has a direct flow right into Lake Lucy and my questions here is why not have the overflow go into the large vegetation acreage to the east and allow a better sense of filtration... OK. Major point No. 2 relates to sensitivities to the physical characteristics of the site. I am very happy to see a cul -de -sac and the road realigned. I think that was a bit of a no- brainer to move the cul -de -sac over and not within the middle of a grove of trees and that was a good thing to do. The realignment of the road also compensated significant trees. I acknowledge that. But there are still significant problems remaining. In the applicant's proposal, and I couldn't tell from the staffs proposal, but in the applicant's proposal there are three 15,000 square foot lots on very steep terrain. If you have your maps in front of you or if Sharmin could put a map up on the overhead you could see that in Block 1, Lots 3 and 4 are 15,000 square feet and located in extremely, that's Block 2, Lots 5, right? That also is in a very extremely sensitive terrain area. In Block 1 if Sharmin could show Lots 3 and 4 right where all those high - density contour lines come together and also they are very heavily wooded as well. I guess I have a question, Sharmin. In your experience, has anyone ever submitted a plan showing 15,000 square -foot lots on this kind of terrain with this kind of tree cover. Al -Jaff: I haven't reviewed a plan with that type of terrain and a 15,000 square -foot lot. I personally have not. Joe Morin: OK. The other area I want to point out is right near Lot 4 and between Lots 4 and 5 there's a 14 -foot elevation difference between the two sites. In fact, Lot 4 is surrounded on three sides with retaining walls 14 to 17 feet high. We're talking about sensitivity to physical characteristics of the site. The private drive going into the Willis property that was shown here and I think that's going to be changed but that shows 13 to 14- foot retaining walls on either side of that private drive and, of course, more important, inadequate access to her property. Now, I'm pleased that the developer, or the applicant is wanting to accept the changes that staff has made. I don't know if the changes that staff has made are an improvement. I can't tell from the layout. But I do have some grave concerns about the way that the terrain, the natural terrain and steep slopes are being torn up in this area. Sharmin, if you could show the drawing that you had before showing the point of setbacks. The point I'm trying to make here and that staff recognizes is that when you have 20 -foot setbacks and you have houses that close to the road on either side you have kind of a tunnel effect. Now, Mike is trying to create an environment that's in the woods. I would expect an in- the -woods kind of environment would put homes in the woods you would have 8 some with trees in the front and some forward. Obviously you would have few lots if you wanted an in -th -woods kind of environment. This submittal by the way does not in any way to me show an in- the -woods kind of consideration. What I'm showing here is part of the plan the applicant submitted at the request of staff to show what could be accomplished if no variances were granted. The lot shown to the top of the page, Lot 9, has no access to it. There is no access there. There is also grading and fill right up to the edge of the wetland here all along the wetland in fact. But there is no access to that point... The applicant can't get to that site without a variance. Now, how many houses he could get on without variances is still a matter of dispute. I understand from the staff report they said probably 4 less than what is submitted. Certainly, if you can't access to a site you can't build. What this one shows is the applicant's current design for Lot 10. I'm going to point out a few things here related to sensitivity and physical characteristics. You'll notice right along the wetland area all along in here there's 10 feet of fill right up to the edge of the wetland. You'll notice that right in the center of this driveway is the loss of that 24" oak that we spoke of. We've been out to the site many times. This is a tree that could easily be saved with just a minimum amount of consideration for this area. With respect to this site there is an ironwood, 12" ironwood here that's not identified on the applicant's plan. We were out there with Jill, the City Forester and the DNR Forester whose had 40 years of experience in this, in forestry and he said this is a very tree. An ironwood doesn't usually get to be that big. It's a very old tree. He also identified another oak in here. He said that was a 12 " oak. All along here are 10 ", 11 ", 9" oaks. There's a whole grove of oak trees in this area. Many of them are on my property right in here. And these oaks will be damaged with this kind of a plan that the applicant has submitted. The applicant is filling 9 feet of fill on this site. 9 feet of fill going right up to my property line here. But 9 feet of fill more importantly between this pond and this lake. He's also showing... a 10 -foot setback from the property line. ...asking for a variance? If the ordinance is 20. I'm gravely upset by this. Putting 9 feet of dirt and then a house on top of that in an area that's this sensitive to the environment I think is a desecration. The basements of all of those sites located in that southern area are at a elevation of 972 roughly and the natural contour's at 964. This could require 8 feet of fill for Lots 7 and 8, 8 1 /2 feet of fill for Lot 9 and 10 feet of fill for Lot 10. I think that staffs plan is alot better in that these work in this area. It's a heck of a lot, a huge improvement over what the applicant proposed. I don't believe that, I think a sensitive plan of these lower sites would have one or two houses there, one or two houses and homes without basements so that no fill at all would be required. I don't believe that this plan adequately addresses the Planning Commission's concerns about sensitivity to the physical characteristics of the site. The third major point is with storm drainage. Now the applicant's proposal, Sharmin mentioned a 10% grade in part of the areas 14% grade. Sharmin, if you could put the applicant's sketch up there again. I don't know if 14% is even reasonable whether it meets the City standards or not. I'll let you be the judge of that. My concern with this kind of a layout is the flow of uncontrolled and untreated runoff coming from the street coming from the properties north of that road that's Lakeway Court flowing at a 10% to 14% grade straight into my property in an area that is already low and takes a certain amount of time in the spring to dry up I think I don't need anymore water from... and this is not addressed. The impact of flowing into our properties is not addressed in this plan. The applicant has still not submitted a plan showing storm sewer calculations. He has still not addressed the concern expressed by Mr. Conrad about erosion control on the southern part of the site which he is still showing as 8 to 9 feet of fill such as previously mentioned. He has not addressed how the lake and pond will be protected either G 1 I 1 1 1 before construction, during construction or after construction. I don't think the applicant has adequately addressed this point either. The fourth major point, environmental damage, who knows what the impact of 8 to 9 feet of fill and dirt will be on the pond and the lake. We don't know that. But the impact of a big house out there after you level all the forest on 9 feet of dirt in the middle of a wildlife migration area which is a travel zone for the entire area, not just our area but the broad areas I spoke of this last time surrounding us, I think its still abusive to the environment. I talked about cutting into the slopes pretty severely. I'm not sure if staffs plan will minimize that or not. I don't believe that the... calculations have been done correctly or are missing. I think there's an issue there. Certainly there is significant tree loss removing 7 acres of trees. Speak of being sensitive to environmental damage I think that's horrible. I still believe there is excessive density for the site. There ought to be 4 to 6 less homes. If you want an in- the -woods kind of environment you have to have fewer homes. With the density that he has, he has to chop down all the trees. I believe that this is a very rare and very unique site. The man from the DNR with 40 years of experience, those are his words. He said this is... We don't see... like this. We don't see oaks like this. Gayle and I took a bike ride out to Eden Prairie around Rice Marsh Lake and we looked at the big woods that they have there that they've been struggling so hard to preserve. This is something like we already have right here in Chanhassen. I think that this is such a unique site that it needs special considerations in its development and that significant pieces ought to be left alone and the design ought to be sensitive to that. Eric spoke of the other environmental issues. He did send a letter to the members of the Planning Commission but you haven't received that yet. I hope that you do take what he says under consideration. He's talking about destruction of valuable natural habitat necessary to support abundant wildlife. He speaks of a beaver lodge newly constructed this year 150 feet from where the applicant wants to level the woods. He talks about the beaver depending on small caliper trees and not being afraid to take the landscape trees that Mike plants. He talked about many too -tall houses close to the lake referring to aesthetics and so on. Natural, year - around springs. He address that. And the storm pond's relationship to the spring and the stormwater flows on the site and he speaks to the developer that the applicant not be unresponsive to staffs and resident's input. I know, I've seen the wildlife there. The fox, mink, deer, beaver. These are the large mammals. Eric spoke of 14 different species of mammals. The red -tail fox, great- horned owls on the property. I saw them there just a few days ago. ... woodpecker, a dozen great blue herons underneath the large canopy trees where they're nesting. Migrating water fowl such as loons. We've heard loons this spring. We've seen pelicans out on the lake. Other waterfowl basically too numerous to mention that nest here and make their homes. This is what Eric spoke of and this is part of the aesthetic enjoyment that the entire community sees for this property. The lack of erosion control and drainage pipes. I have serious concerns for this. This is a very important watershed area. This is the headwaters of Lake Lucy which is the headwaters of the entire chain of lakes, the Riley chain of lakes. And so pollution into this area not only affects Lake Lucy but everything downstream. The development that's occurring here is in a natural basin. The Mason homes development is high on a ridge where they have pulled their homes away from this natural basin. They left it natural. My home is high on the basin. The Tichy home is also high on the basin. Christensen's and the Willis property are also high up on the basin but now we're taking about developing down into this basin and Lake Lucy gets most of its flow from groundwater seepage and runoff from this area and we better be real careful about what we do there. I don't think that, I believe that a much higher standard of care must be 10 exercised in this area and I don't believe the expectations of the Planning Commission have been met yet with this plan or with staffs plan either for that matter. The fifth major point was variances. I'm going to go over that very quickly because Al talked about them. There are several variances that area being requested. The question is has the applicant earned the right to these variances? Has the applicant earned the right to private driveways and so on? I really worry about the history of this applicant. I don't know that he has experience with this size of a development, let alone a development that requires this degree of sensitivity. I have very grave concerns about the wherewithall to complete the development which is sensitive to the area. Even this could be mitigated if he at least was cooperative with the planning staff. But I'm worried about the history of him using variances simply to cram in more lots and not preserving the environment. So, I'm worried about that and I'm worried about his lack of cooperation. There are numerous citations that we have in the letter that was sent to each of you showing his unwillingness to work with the concerns of the staff, the concerns of the Planning Commission and the concerns of the neighbors and local residents. He didn't even take notes at our neighborhood meeting. Sharmin, have you ever in your experience encountered a more uncooperative residential developer? Mancino: Mr. Morin, all those... Joe Morin: Is that a fair question? Mancino: No. That is not a fair question. Any questions should be directed towards me. Thank you. Joe Morin: I would ask you the same question... If you think it's inappropriate I'll... Mancino: It's inappropriate. Thank you. Joe Morin: I think that staffs layout has some improvements. I think the applicant's reaction to it is very disappointing but not unexpected. I appreciate the long hours and hard work that staff has put in and overtime to try to get to an acceptable plan. Unfortunately, I don't think we're there. What we have here is a layout and a sketch. We have the document that was submitted to Planning Commission members but not the staff. I have no... We have kind of a hybrid between a sketch and recommendations of staff and the applicant's choosing not to accept so I'm really not sure what we have. I want to conclude with just making two points here. Number 1: As I tried to show I don't think your concerns have been adequately addressed by the applicant. I think that staffs layout is better but undefined. I'm still confused by this hybrid of the south and north and the unknown document. Number 2: The applicant, I'm upset by his not agreeing to the changes recommended by staff. I think its still a plan even in its hybrid form that's unacceptable to staff. I think its unacceptable to the Planning Commission. I hope it is. Its unacceptable to the residents and will most certainly be sent back by the City Council. This forum is here to stay. Gayle and I just... that anything looking like this request that a preservation easement be placed over all the property outside all of the grading limits. We request that Lot 10 be eliminated. We request that homes without basements be placed in southern area if any homes are put down there at all. We request that Lakeway Court be realigned the way staff has proposed and the rest of the project be re- engineered as shown in the staff layout. Finally, Gayle and I can accept the 11 development next door. We'll even profit from the development next door. But we don't want it rushed into the City Council in this form. We believe that the site deserves a better effort. A much better effort. We believe that the City Council should be presented a clean plan. A complete plan. A plan that is much more responsive to all of our concerns and we request that this application be tabled. Thank you. Mancino: Thank you. Anyone else like to approach the Planning Commission? Jill Willis: Hi. My name is Jill Willis. I'm the property that's to the west. I have a couple of questions I would like to just coincide on Al's and Joe's comments. Sharmin, could you put up the... Tape ended at this point. Submitted by Kate Aanenson Planning Director Prepared by Kim Meuwissen 12 Planning Commission Meeting - April 5, 1995 9.

Conrad: Just one question of staff. Any applicant has the right to bring a plat in front of us. Al -Jaff: Correct. Conrad: Whether it meets our standards or not. We are obligated to look at that, even though it's obviously missing some things that we require by ordinance. Correct? Al -Jaff: Correct. I mean we could have said that this was an incomplete application. However, we just wanted to get the thoughts of the Planning Commission. We wanted to 10 t P 1 Planning Commission Meeting - April 5, 1995 make sure we're moving on the same track. And we wanted to get your input on it. But yes, you do have to review the application. Mancino: With that, is the applicant here and would you like to make a presentation? Michael Byrne: Madam Chair, members of the Commission. My name is Michael Byrne. I reside at 5428 Kimberly Road in Minnetonka. Normally under the circumstances ... speaking to his proposal. That is not our intention ... We are working with staff and staff has been very gracious in working with us. We are in mid stream ... We met with the neighbors last night and learned a lot of commentary. Madam Chair was there so she... I don't want to take a lot of your time since...I wish however to garner as much information from you as possible... You will hear from the neighbors. Mr. and Mrs. Morin ... I can only ask that we continue to have the opportunity to work with staff and working with... I had made plans with Alan Olson myself but Sharmin from staff has stole my thunder already. To give you an idea of the... The changes that we're trying to make to this proposal are going to be hard. This is a very, very difficult subdivision. We have somewhere between 72 to 78 percent coverage of trees. We have terrain changes. We have ponds ... We really do wish for you to listen to those comments... await for any questions you have. Mancino: Any questions? Conrad: Not right now. Mancino: Thank you. May I have a motion to open up the public hearing please? Nutting moved, Conrad seconded to open the public hewing. All voted in favor and the motion cwiied. The public hewing was opened. Al Weingart: My name is Al Weingart. I currently reside at 5320 St. Albans Bay Road over in Shorewood. I recently purchased the island peninsula out in Lake Lucy and also will be purchasing the Sanda home which is at 1685 Steller Court. That's the Sanda home. And relative to my intentions with respect to the island, you guys went through it and the City Council and they approved a plat of a roadway that goes out there that will only service a single family home so my intention all along, after that process was over was always to put a single family home at some point. No immediate plans to do so, but that is why we're buying the Sanda house is to give us some time to acclimate ourselves to the neighborhood and what not. It's a fairly big project so it's going to take some time and more importantly money. General concerns from a personal standpoint are that, the concerns about the economic impact that such a development, as was originally proposed, will possibly have on my property, which is a selfish interest. And of course... shared by many people in the neighborhood. And 11 Planning Commission Meeting - April 5, 1995 also on the quality and the level of Lake Lucy. I have a real concern about the level of Lake Lucy, not only from Mike's development but also from the standpoint of some of the other developments around Lake Lucy because my driveway doesn't sit much above the ordinary high water mark and I don't want to be using a boat to get to it. So those are the personal concerns that I have about this particular development. I'm not opposed to development. I just wanted some sensitivity relative to those kinds of things looked at. Overall I think my concerns would be to preserve the natural, sort of preserve, nature preserve setting of that whole area of that north shore. We don't have a lot of lakes in Chanhassen and I think the city character of the lakes, would surround the lake changes dramatically although I'm not naive enough to think that it wasn't going to be developed or shouldn't be developed. That's not our position at all. Just that it be developed responsibly. Also there's, as you may know, there's some wildlife in that area, both on the island and all along this shore it's heavily forested. I think Eric Rivkin will talk a little bit later about some of that but that is a concern. There is a buffer zone that, where this wildlife seems to migrate to and from across all of that all the way out to the western part of Chanhassen so that is a concern. Again I want to reiterate we're not opposed to development at all. We had a meeting last night, and Mike was gracious enough to call with all the homeowners and we have some Minutes put together that Joe will distribute to you and they can ... comments so we're here to kind of give you those rather than sit here and reiterate what's in that packet. Sharmin, could you put this up? Al -Jaff: I sure can. Al Weingart: This, again this is a bit preliminary but my point of putting this up here is just to emphasize, it's backwards. What the initial thrust of this whole development has been and what we've done. You've got a copy of this in a March 28th letter that I distributed that Joe and I ... distributed to you and basically the second portion is what, at that point in time, was deemed to be graded to accommodate the home sites. That means all the trees and the slopes would be impacted by the grading. And this initially of course shocked us because really it amounts to about 80% or 90% of the lot. What isn't graded, it consists of very steep slopes, a buffer zone around the wetland and wetlands themselves. And so that kind of caught our attention and that's what caused us to create a bit of an organization here to just make sure that what is done here is done with some sensitivity. Some of the points on this are that what we're concerned about is really four things generally. The areas along the right hand side. Right along the water front, or the lakeshore if you will. I'll call it lakeshore. Basically it's very low. There is a proposal to range from 8 foot of fill to be put in there to build up those lots in order so they can have walkouts and look -outs. That I understand may be being revised to 3 to 4 feet but nonetheless when you fill that site, basically you've got to get rid of all vegetation because you fill with dirt on top, so that's a concern. Between the wetland, the inside wetland. That pond. The big pond and the lake. It's a very sensitive area in there. 12 1 Planning Commission Meeting - April 5, 1995 It's very low. That is, and over to the top. That is an area that's particularly I think critical and I think Eric may be able to speak a little bit to that. This plat here and in subsequent to the conversation plat I guess, whatever it was, had a lot of variances, or needs a lot of variances to accommodate the number of homes that are being put in here. Particularly the private drives that are necessary for that, and I think those should be taken a look at very carefully to make sure that we're not impacting something by putting too many homesites. And I know the pads aren't necessarily the ... factor of this whole but it still defies my logic a bit that the more homes that you have in a situation, obviously the more trees that go down and the more slopes that get graded and so that explanation of the pads aren't really that important has not really flown with me and I wish somebody would articulate that to me... That proposal incorporates taking down some very large trees, 24 inch plus in diameter trees and particular in the cul -de -sac area. I don't know how much concession Mike is going to do to move that cul- de- sac ... to avoid those trees. I haven't heard anything ... but that would be something that we would like to see... Basically the issues we'd like the Planning Commission to consider would be to, a reduction in the tree loss. A reduction in the grading of the site. Custom grading of the lot which last night Mike had agreed to. Reduction in the number of lots. Focus on the retention pond location. There's a retention pond that sits right next to the wetland. A pond there and we're concerned about it's ability to hold water and not dump it into the wetland pond which flows directly into Lake Lucy. And probably some of the most severe concerns of our's happen to be, and these were brought up last night in the homeowners meeting, were the number of lots that are on the lake, or even the fact that there's any lots on the lake. To have those things moved back away from the lake. They're awfully close to filling with a lot of fill there and there's a lot of wildlife and other types of concerns about what impact it will have, not only on that situation but also on Lake Lucy itself from... standpoint. And I would encourage any of you who haven't walked the site to do so because I think you can't really appreciate the undulation of the land and trees and everything until you've been out there. And I encourage you and whoever else is involved in the process to do that. That's all I have right now. Any questions? Mancino: Any questions? Thank you. Al Weingart: Thank you very much. I Mancino: Anyone else? Joe Morin: Madam Chairperson and members of the Planning Commission. My name is Joe Morin. I live at 1441 Lake Lucy Road. Last time I was here about a month ago I spoke to you, mainly in support of the development going in to the east of my property line. It was not complete support. I had some concerns. Those concerns have been taken care of by the developer. Tonight I'm here before you speaking mainly in opposition to the plan proposed 13 L Planning Commission Meeting - April 5, 1995 on the west of my property. The differences in the developments, although as Mike last night told the neighbors, he was patterning his development after the Mason Homes development. The differences are dramatic, notwithstanding the name that he's chosen. Also the character of the land is quite dramatic. I would like to just kind of show a little overview of some of the differences. The Mason Homes development is laid out on a ridge. Mason Homes took great consideration from the recommendations of the staff to reduce some of the grading originally proposed. They reduced the number of lots which reduced the impact on our property. The President has agreed to move some pine trees between our property and some of the adjacent homes to further reduce the impact on us. So our relationship there has been quite good. The topography is significantly different, as the staff report points out. The Mason Homes development is on a ridge, whereas the Tichy, Byrne development is located kind of in more of a ravine area, which is also heavily wooded. Sharmin, if you could put up that. These are some numbers that I gleaned from the staff report. The bottom line here is that in the Coey property, buildable acreage, I think I can read that from here. Is 11.1 acres. And the buildable acreage on the Tichy /Christensen property is 7.97. Now I want to emphasize and stress here that it's not the number of lots that's my main concern but rather how the land is treated. I'm only showing this to kind of emphasize the differences in the two developments. If we use the same ratio and apply it to the Tichy /Christensen property as the Mason Homes development used in creating their plat. That would suggest that 13 to 14 building sites would be compatible. Not as a compatible development. Not even considering the more difficult terrain that we have to deal with on that site. The status of the development to the east of my property is, the neighbors are, I don't plan to speak for all of them but in large part, most neighbors are well satisfied with what went on there. And to the west of my property, most neighbors are very unhappy about what's proposed. So, I want to also emphasize that I'm not opposed to development to the west. In fact, Gayle and I will benefit from a development to the west greatly but we want to see a good development, and we would rather have no development than what we see being proposed right now. The intentions that we have with respect to our property, I want to make that clear. We have 3 potential sites, 3 developable sites on our property, one of which we have already developed. That's our present home. When we put our home in, we built it, I cleared the area by hand. There were no significant trees that were removed. There's no grading for the site required except to put in our driveway. We designed the home with the site in mind and took about 3 years before we actually, after owning the property, before we actually built a home on this site. The second site is located a little bit southwest of our existing home and in that area, I have to acknowledge that there is one significant tree. That staff asked us for conceptual plan potential homesites so we don't know exactly how that, where that tree fits in the site but it is something that is a concern to us. The third site on our property is south of the slew area, which is again more south and east of our existing home. And that's in a natural clearing so the only brush that would need to be removed, I think right now from my walking the site, although I'm not exactly certain where the boundaries are, it looks like it's mainly ... and 14 P1 in - S 1995 Planning Commission Meeting April , buckthorn. So the net impact on our 5 acres from any future development plans that we would have would be removal of basically one significant tree. Possibly removal, but we'll do our very best to avoid that. Although like I said, we have not platted the property. We don't know what the implications are for the runoff and so on from that kind of development. I think 3 homes on 5 acres is something quite reasonable, and in dealing with the character of the property, we've taken great care to avoid any tree loss or any other ... impact to the ' environment. Now the main concerns with what's proposed there. Not with the number of lots, as I said before but rather how the land is treated and Al has spoke to many of the concerns that I share with both Al and the rest of our neighbors there. I'm not opposed to ' Mike Byrne developing but I do object to the callousness with which the, and the insensitivity of the design process that's used and the results of the plan that's being proposed. I don't feel that it does deal sensitively with the environment, and that's of grave concern to me. Ironically one of my biggest concerns is in the area furthest from my house, and that's in an area where Al spoke of where right between these large ponds on our property and on Tichy's property, and the lake, the plan is to bulldoze the area, putting in up to 8 feet of fill and erecting a house on top of that 8 feet of fill. Not only is there tremendous destruction to the local environmental there, and Eric will speak to that later. But it's a major block and impediment to the wildlife migration path. Sharmin, if you could put up the, well that's a ' little bit of a representative drawing but. Al -Jaffa Like that? Joe Morin: A little bit. In that proposed Lot 10 there, the end lot. The land is very much constricted in that area but the wetland area to the east and to the west widens broadly in I those areas and on the Mason ... as you travel further west there's a very large wildlife wetland area. And so I see that as a very constrictive impediment to the free travel of the wildlife. Not just for this site but for the whole region. The whole area. Not to mention that a home r positioned on top of 8 or 10 of fill would be a tremendous eye sore for the whole area. Now my other concerns I share with the neighbors. I share with Al. We brought those out in our meeting with Mike last night. Mike didn't take any notes during that meeting but Al and I i consolidated our notes and put together the Minutes of the meeting and I'd like to provide each of you with a copy so that this can also be, and Mike with a copy, so that this ' neighborhood input can be considered in the further improvement of the plan. We also have copies for people who participated in the meeting and any other neighbors who are interested in obtaining copies of the Minutes, they can call myself or Al. Again, I don't want to take a ' whole lot of your time reiterating concerns that are already documented in these Minutes, so thank you very much. Mancino: Appreciate it. Thank you. Anyone else like to speak? ' 15 Planning Commission Meeting - April 5, 1995 Eric Rivkin: My name is Eric Rivkin. I live at 1695 Steller Court, which is just to the west of this development about 400 or 500 feet, and I share lakeshore on the other side of the island. Opposite side... I'm also Co- Chairperson of the Lake Lucy Homeowners Association. I went to the neighborhood meeting last night. I've read some of the concerns that Al and Joe have had. I've read the staff report. I used to own Joe's lot, sandwiched inbetween both of these developments, and I know both pieces of land ... very intimately because I had owned it for a year. Picked lots of raspberries there. Watched a lot of wildlife and meditated out there. It's really quite a place. I think this is somewhat of an inaccurate depiction of the lake. That edge right there, that you see between the water and the land is really the edge of cattails. The actual high water mark goes more around here. You can connect the dots I guess. It goes around here and goes way up in here. The proposed setbacks from here really put a strain of the water quality of the development. It's very clear right now. There's a lot of beavers and muskrats that excavate this area. They depend on a corridor between here and a pond to be able to traverse. The whole area around here, around Lake Lucy and this side of the lake primarily is basically a giant wildlife refuge. There's flocks right now of Great Blue Herons that do nest in there. There is a rookery here. They nest in the large tree canopy that surrounds this pond. If that integrity of that tree canopy is destroyed, which it will be on this side of this lot, I talked to wildlife biologists today, who works for the St. Paul Parks System and she has manages the park at Crosby Farm where they have migratory waterfowl there all the time. And she said if these are disturbed, they're very sensitive to being disturbed and they will leave the nesting sites. So we will lose that. It's an environmental impact that is serious. The other particulars from the environmental issues. There's many water ... I'm concerned about. I saw a plan Michael produced last night that had a Walker Pond or something next to here. I want to comment that I think is potentially disastrous. We have, I know that 4 years ago when Willow Ridge was proposed, there was a lot of talk about, it was an experiment. This Walker Pond concept. There was a pond put right on the edge of this giant 1.4 acre pond, which is about the same size as this one. And the theory was that the water would drain into there. Hold the sediment. Hold the nutrients before it would dump itself into there. Well, the water level was planned to rise. Well the whole thing, including the Walker Pond, is all underwater as the same continuous lake right now. So there is no benefit derived from this Walker Pond. The same thing is proposed here. The same detriment will happen. The water quality will not improve. It will go down. If that is, the difference between this and the Willow Ridge is they have 3 or 4 Walker Ponds for that whole development. This has one and it was located right smack in the middle of the most sensitive part of this development. Or sensitive part of the drainage. Highest impact. Potential impact it would have on water quality. This pond drains into Lake Lucy with a running stream right now. There's water flowing in it now? From what I heard. Joe Morin: Oh yeah. 16 J 1 0 I r r Planning Commission Meeting - April 5, 1995 Gayle Morin: Almost all the time. Eric Rivkin: Almost all the time. There's springs that feed into this, okay. And there's no filtration between here and Lake Lucy. You dump high nutrient loading into this storm sewer system here, it's going to go right into Lake Lucy. Unfiltered where you cannot harvest the nutrients, the phosphorous away. So it's lacking in design and I need to state that on record so that Mr. Byrne will take that and hire the appropriate resources to make sure that it meets ordinances when it comes to water quality interception. There are springs in the area. There's running springs that come flowing out sprinkled all throughout the Lake Lucy area. I think there's one here. From what I remember, there was one over on Jill Willis. There's several on Jill Willis' property. There's one right here ... because I saw it coming right through the snow. I think there's one or two right here. I think engineering wise, Mr. Byrne is going to discover that if he puts a house there, I don't think he will be able to. There are running springs that keep the deer, who come and nest there ... or bed down every single night in this region. There also, I don't think that it was very sensitive to put a cul -de -sac right in the middle of a grove of mature oak trees when 30 feet from there, you could just move it and terminate it likewise. The impact of putting large amounts of fill on here will destroy the natural, I guess filtration that would be left between here and there on the development. I think this would be a good place to have maybe your retention pond and open space that would be left for wildlife. This was brought up in a neighborhood meeting last night as a strong suggestion that was agreed upon by all the residents. And I think the economic impact of doing something like that, reducing the number of lots to maybe 9 or 10 where you have an amenity that would improve the value of the homes to the point where I don't think he's really going to lose any money. I developed some land in Minnetonka, 4 acres and put 6 lots in. It had 90% of the existing tree canopy was preserved because I wrote in the covenants, and I suggested this to Mike last night. We had covenants that would say the developer, which is me, would have right of refusal for any builder to come in and cut a tree. I would say it can be cut or it can't be cut. Or I can approve your design with this house so you can tuck it in here and there. Whatever. But that kind of environmental sensitivity is lacking here. If Mr. Byrne doesn't have it himself, I suggest that he retain the services of a developer and we suggested to him a name that, retain the services of some professional who can satisfy that type, to design it environmentally properly. Well, let me get back to my sheet here. The oaks. As you heard, almost all the oaks on this place are red oaks. I had a red oak on my place when I put my house in. I was trying to be very, very careful not disturbing out to the tree line and I like the idea of having them report 1 1/2 times the drip line and not disturbing key trees. Well, destroy all the trees ... but in order to, I've seen houses by a sensitive builders go right up within 10 feet of a dripline and not destroy a tree because they knew how to build next to it. It's possible to do that here. You just need some talent to make it happen. I'm concerned about the fact that the trees themselves are home to many species of animals. The holes and they come in trees ... but also the mallard ducks. They eat the acorns and the 17 Planning Commission Meeting - April 5, 1995 mallards, and I know I'm right about this, they flock there by the hundreds during migration and they do nest there. Every single year. They need the food. They need the perch space. They need the tree canopy. They need those oaks intact as much as possible. And I don't think that, I would have to believe that there's enough teeth in the ordinances we have to say no to this level of destruction. Simply saying to the developer it's okay to destroy everything as long as you replant or, just does not meet the intent of the comprehensive plan. And I think that Mr. Byrne can take that and use that as an important thing to preserve. There is beaver sitting right there on the site, in the lagoon to the south of the property. They've been cutting down some saplings on the island and on Christensen's property. Byrne's property right now. And right between the pond and the lake. Now if you put houses in there, some neighbor's going to get in a house and want to shoot them and they need to live. They need to, we have to ... to the needs of the beavers here and there's a beaver lodge in that lagoon right now. It's been there for many years and they keep building new ones all the time. Every year they try to come back. And they need to live so we have to... Well, thank you very much. Mancino: Thank you. Anyone else? Would you like to come up? Thank you. If you could give your name and address. Jill Willis: My name is Jill Willis and I own the property adjacent to the ... Tichy property and essentially I just want to say for the record that there are... development as has been proposed would be pretty tragic... Mancino: Thank you for your comments. Anyone else? May I have a motion? Conrad moved, Nutting seconded to close the public healing. All voted in favor and the motion carried. The public hearing was closed. Mancino: Thank you. Comments from the commissioners. Ladd? Conrad: I'm going to speak in a two part. The first part relates to our subdivision ordinance, and then the second part relates to my personal feelings in how I'd like to see this property develop. In the subdivision ordinance I think there are, at least there are 7 major points that the staff has outlined and basically this development, or proposed development, misses the first 5. From the standpoint of variances. From the standpoint of water quality pond that should be there. From the standpoint of sensitive to the physical characteristics of the site. From the standpoint of storm drainage. From the standpoint of environmental damage. And these are not, I guess I'm not saying that personally, there are not personal comments. They're just my review of the ordinance versus the project and the project fails in 5 out of 7. Maybe the reason I started this conversation off with why is this here. In terms of how it 18 ' Planning ommission Meeting - April 5 1995 g g P , should be developed. I'm going to echo a couple things that staff has said. I think staff has done a good job of reviewing this. I think they've given us good input. I'm pretty comfortable with that staff is trying to guide this. So I think the developer, the owner, I think as you work with staff, they're really going to represent a great deal of, at least my philosophy and I think it's philosophy that's carried out through the ordinance. The subdivision ordinance. So it's not Willy nilly. It's not personal opinion. I think it's substantial defensible, solid guidelines. In terms of how, what I would recommend. In terms of my concerns as to how you make this a development that works. We know that developments can work. We've seen them in the neighborhood. We've seen the neighborhood actually support them so I don't think the neighbors are out to say, don't develop. They're not. I didn't hear any of the neighbors say that. I think it's how we do it. And I've got a couple observations and the first one's going to reflect staffs comment. I won't approve any variances unless we see an environmental sensitivity. Just flat out, I'll trade. I'll do some horse trading. But right now it's all one sided. I'm real nervous about the 8 feet of fill on the south part. Regardless. 8 feet next to the lake for so many reasons. Now maybe it's not 8 feet. Maybe it's 4. So we'll find out. We don't have a real plan in front of us but even real well designed water quality ponding has problems. And so when we start hauling in 4 to 8 feet of fill for 4 lots, that's a lot of fill right next to the water. It's just extremely nervous about that. I don't know how you manage it during the fill. I don't know how you manage it after the fill, to tell you the truth. Erosion control. The impact on the natural habitat. It seems abusive to me. But most importantly I don't know how you manage ' 8 feet of fill going in there to not impact the lake. And Dave will say, engineering we can do anything. Obviously there has to be some storm water ponding. Storm water ponding on site. Obviously. I don't like to look at plans that don't even have it. It says hey, it's not a real plan. This is a game we're playing here. The site, as I saw it, looked like every street was aimed for a tree over 24 inches. And I say that in jest. I don't want to be perceived as taking shots here but, I'm not going to force somebody to preserve every tree on this site, and you don't have to and nobody does. But when I see all the major trees on this site that are coming down, it's bad design. So that, and I know you can fix that. So I won't even extend my conversation that I know we can miss those trees. Custom grading has to be done on ' every lot. And the cul -de -sac has to be moved. Those are my comments. Mancino: Thank you. How did you say what I had written down? Ron. Nutting: Yeah. Very well done Ladd. I guess one initial comment I would like to make is I ' do appreciate the developer's comments about, I guess first in holding the neighborhood meeting. The projects that get to this point without the neighborhood meetings really seem to not go anywhere. And holding that meeting I think was a good start. As well as the expression of willingness to work with staff and make revisions to the plan. I'm not a developer. I rely on staff and I think staff does a good job, for the most part. No, staff does ' 19 C Planning Commission Meeting - April 5, 1995 do a very good job. So when I read the staff report, as well as walk the site, and maybe just to echo one of Ladd's comments. The area where the cul -de -sac is and the grove of trees at that location. Without greater sensitivity to tree preservation, as you acknowledged, the site is heavily wooded. Trees will go down. There's no question about that. We're not here to save every tree but just to responsibly assist in the responsible development of the site. I would echo all of Ladd's comments and again I can't comment further because I'm not sure what we're going to be looking at, and as you acknowledged, but I think the neighbors comments bear some review and the process but I think staff has done a very good job in trying to shape the thing, the plan so that as Ladd puts it, variances require some effort towards I guess sensitivity is really a big issue so those are my comments. Mancino: Thank you. Mike. Meyer: Really just to echo the same thing that Ladd has said already. I can't really add anything to it but just go on record as saying that I agree with him 100 %. Mancino: Alright. Did you get his comments Mr. Byrne? Michael Byrne: Yes. Mancino: Did you get his comments were the same? Thank you. I also echo, would like to comment on the same concerns that I have. I'd like to add just a few more. One are the retaining walls that I saw on the plans, knowing that they're not final but if there are going to be retaining walls in the next version that we see, I'd like to know a little bit more about them. These were 100 to 400 feet long. So I'd like to see, why are they there? What are they preserving? How high are they? How are they going to be constructed? From an engineering point of view, and from an environmental point of view. Because I think that we had, or what I saw were 8 of them. My other concern is about the accesses to the properties on the east and on the west, and that would be the Willis' and Morin's. And I would like to see the developer and staff work with the property owners on both sides as far as where exactly those access points will be. Not only for roadway but for sewer and water. And I would like to make sure that all parties, if we get there, are in agreement on where those are. And that they do take into the environmental concerns that we have. And I have some concerns about the construction of a private street. Making sure that we do not limit, on either side of the property that's going to be developed, what the other owners can do. That means that if there's a limit to 4 houses on private drives, that it comes back to us. If we want to see 5, that there are very clear illustrations as to how that is preserving that area. I concur with Ladd that I need a very good explanation, something that I can understand about the necessity for the amount of fill in the southern portion of this property. Not only having to do with walkouts but having to do with sewer. And some other options besides that amount 20 1 Planning Commission Meeting - April 5, 1995 of fill. The location and the size of the retention pond I would like to have staff and the applicant work together to locate it in an area that will not destroy significant tree coverage, and at the same time will be effective storm water quality treatment pond. And it would be my recommendation to staff and City Council that maybe you consider conferring with or getting a second opinion from an outside expert on that. Not only the location but how effectively it will work. 100% of the time... And I guess just in summary I would like to say that I would just like to see the plat comply more with the subdivision ordinance 18- 60(d). Lots shall be placed to preserve and protect amenities. Natural amenities such as vegetation, wetlands, steep slopes, water courses and historic areas. And I'd like to see this comply with that ordinance. Those are my comments. Conrad: I'd like to make a motion Madam Chairman, I'd recommend that the Planning ' Commission tables action on Rezoning #95 -1 and Subdivision #95 -3 and to have the applicant work closely with staff to resolve some of our concerns. Mancino: Do I have a second? Nutting: Second. Conrad moved, Nutting seconded that the Planning Commission tables action on Rezoning ' 495 -1 and Subdivision #95 -3 and to have the applicant wont closely with staff to resolve the issues outlined by the Planning Commission.
