The property is zoned RR, Rural Residential and the proposal calls for rezoning it to RSF, Residential Single Family. The average lot size is 31,986 square feet with a resulting gross density of 1.04 units per acre. All lots meet the minimum requirements of the zoning ordinance as relates to the area, width and depth. 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 43%or 4.84 acres. Additional tree replacement will be required. Some of the parcels are shown as custom graded lots. The type of future home is not shown on the plat. This will result in additional tree removal and staff can not assess the extent of grading impact on the trees without this information. This application appeared before the Planning Commission and City Council in 1995 under a different applicant(Mr. Michael J. Byrne). The 1995 plan reflected 23 homes and, after numerous revisions, resulted in 18 home sites, massive retaining walls,mass grading in some areas,and excessive tree removal. The applicant eventually withdrew his application. Loscheider Custom Homes, Inc. decided to purchase and subdivide the property. The new proposal contains an in depth analysis and comprehensive forest management plan for the site. This plan does not attempt to preserve any more or less canopy than the previous plan, however,the applicant has invested time and effort in preparing a forest management plan for the site and the future development. The overall number of lots has been reduced from 18 to 17 single family lots. Staff must point out that Lot 6, Block 2,has enough area to be further subdivided in the future and the development could result in 18 lots. This will also translate into additional grading and tree loss. Due to the topography and tree coverage on the site, staff recommended the applicant utilize private driveways, increased number of homes to be served via private driveways, reduced front yard setbacks, narrower right-of-way and steeper grades on the street to minimize impact on the site. The 20 foot front yard setback variances on three of the lots is promoting the preservation of trees and wetlands. The ordinance requires a 30 foot front yard setback. We believe it is warranted. The 10 foot side yard setback on Lot 6, Block 2,will minimize impact on trees located to the west of the lot. The zoning ordinance requires a 20 foot side yard setback on flag lots. The street grade on Lakeway Drive is 10%. The ordinance allows a maximum grade of 7%. The public right-of-way is 50 feet wide and the ordinance requires a minimum of 60 feet. This variance will minimize grading. The last variance deals with the number of lots served via a private driveway. Currently, there are three lots proposed to be served via Lakeway Court. The property located to the east of the subject site has the potential for subdivision and could result in two additional lots. The only access to the two potential lots is via Lakeway Court. The total number of lots that will be served via the private driveway is five. Requiring the applicant to build a City Street will result in excessive grading and loss of mature trees. To date, the City has not approved such a variance, and though staff is cautious not to set a precedent, we believe in this case the variance is warranted. It is highly unlikely that we will encounter a second request similar to this one. Lake Lucy Estates May 20, 1998 Page 3 The property to the west of the subject site has the potential for subdivision also. The only access to this property will be via the subject site. The applicant is stubbing Lakeway Lane to the edge of the westerly property line. The rezoning of the property from Rural Residential to Residential Single Family District is in compliance with the comprehensive plan and staff is recommending approval of it. Utilities must be extended over the property located to the west of the subject site. The applicant must acquire all necessary easements from the owners of the property. The development contains two existing home sites(Tichy and Christensen). Both of these home sites are currently on their own well and septic system. The existing home on the westerly portion of the site is proposed to be removed. The other home(Tichy) is proposed to remain on Lot 4,Block 3. Both on-site well and septic systems will have to be abandoned in accordance with the city and sate health codes in conjunction with this development. The well and septic on the Christensen site will have to be abandoned in conjunction with site grading. The well and septic system on the Tichy property (Lot 4, Block 3)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. Staff is recommending approval of this application with variances and conditions outlined in the staff report. BACKGROUND This application first appeared before the Planning Commission on April 5, 1995. The subdivision included 23 single family lots but through work with the applicant,the total number of lots dropped to 18 single family lots (copy attached). The application included the following requests: 1. Rezoning of 14.53 acres of property zoned RR, Rural Residential to RSF, Residential Single Family 2. Preliminary Plat to Subdivide 14.53 Acres into 18 single family lots and two outlots, Lake Lucy Estates 3. A Variance to Allow a 20 Foot Front Yard Setback, a 10% street grade, and a 50 Foot Wide Right-of-Way, a 10 foot side yard setback, and five homes to be served via a private street. 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 reappeared before 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. Lake Lucy Estates May 20, 1998 Page 4 On May 17, 1995, the Planning Commission reviewed a plan that incorporated most of staffs recommendations. The proposal was approved with conditions. On June 12, 1995,the application appeared before the City Council. After discussion and listening to residents and comments from the City Council, the applicant withdrew his application prior to the City Council's vote. REZONING 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. 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 1.04 units per acre and 1.87 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 consistent with the Comprehensive Plan. PRELIMINARY PLAT The applicant is proposing to subdivide an 16.40 acre site into 17 single family lots. The density of the proposed subdivision is 1.87 units per acre net after removing the roads (2.08 acres) and wetlands(3.39 acres). All lots exceed the minimum 15,000 square feet of area, with an average lot size of 31,986 square feet. The width and depth of the lots meets ordinance requirements. There are a total of three lake lots shown on the plan. However, Lot 6, Block 2 has an area of 101,372 square feet and a width of 303 feet. The ordinance requires a minimum lot area of 20,000 square feet for riparian lots. This parcel has the potential for future subdivision. There is a side yard variance associated with this lot. The ordinance requires all riparian lot to maintain a 20 foot side yard setback. The majority of mature trees are located along the east side of the property. Allowing a 10 foot side yard setback will maximize the distance between the house pad on the subject lot and the trees. Staff is supporting a 10 foot side yard setback on the westerly lot line of Lot 6, Block 2. 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 on the plan(Lot 7 and 10, Block 2, and Lot 3,Block 3). The street alignment could be modified slightly to the east, closer to Lot 7, and the retention pond moved to the west between Lots 3 and 4,Block 2, to minimize impact to trees located on Lot 7,Block 2. Lots 5, and 6,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 9 and 10,Block 2 and Lot 1, Block 3. 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 9 and 10, Block 2 and Lot 1, Block 3. 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. Lake Lucy Estates May 20, 1998 Page 5 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. GRADING The plans have incorporated many design changes that staff had proposed previously. Those changes include custom grading wooded lots, increasing the street grade (Lakeway Drive)up to 10%to conform better with the existing ground contours which results in less grading, adjusting building pad locations and/or changing dwelling types to conform with existing ground. However, staff believes there still are modifications that can be completed to improve the overall site and reduce grading and tree loss. One such change would be to shorten the cul-de-sac and shift it easterly approximately 20 feet. In addition, relocate the proposed stormwater pond to the west side of the cul-de-sac and lower the cul-de-sac grade a minimum of one foot. This will result in saving significant oak trees which lie on the easterly side of the proposed cul-de-sac within the proposed stormwater basin. The west of the cul-de-sac is basically void of vegetation and may add an amenity to the proposed dwelling. One drawback of relocating the stormwater pond would be the lowest floor elevation on Lot 4, Block 2 would be affected. The City and Watershed both have a restriction that requires a lowest floor elevation of a building adjacent to a stormwater pond or wetland be two feet above the high water level. The grading plan also proposes custom- graded lots in the wooded areas with the exception of Lots 7 through 10, Block 2 where mass grading will occur to prepare house pads and Lakeway Court. The sanitary sewer is proposed along Lakeway Court which would take a swath a minimum of 40 feet wide due to the depth of the sewer regardless. Staff has learned from previous developments that front yard trees over time eventually die due to construction impacts. Therefore, staff is comfortable with the proposed grading of these lots in an effort to minimize tree impacts on the back portion of these lots. As you will note, the grading plan incorporates grading outside of the 50-foot wide right-of-way. City Ordinance requires a subdivision to dedicate 60-foot wide right-of-ways and 60-foot wide radius in a cul-de-sac. The plans are proposing a 50-foot wide right-of-way and 50-foot wide radius cul-de-sac. Staff believes that a 60-foot wide right-of-way could be dedicated without impacting too many of the lots; however, given the very steep terrain on the northerly half of the project,the additional right-of-way would increase the setbacks for the homes thus creating additional fill for driveways and dwellings which, in turn,would affect existing tree canopy coverage. Therefore, staff is comfortable with permitting a 50-foot wide right-of-way; however, the cul-de-sac will need to be 60-foot radius to provide adequate room for snow storage and utility improvements. According to the grading plan it appears the site will be short on material. Staff anticipates the applicant will need to import material to develop the site. The applicant will need to supply the City with a haul route and traffic control plan for review and approval prior to site grading commencing. In an effort to reduce grading and tree loss, staff is recommending that a retaining wall be incorporated in the northwest corner of Lakeway Drive and Lakeway Lane. In addition, retaining walls could be further extended along private driveways to minimize grading and tree loss as well. Lakeway Court also needs to provide for a temporary turnaround acceptable to the City's Fire Marshal. The temporary turnaround could be created on one of the lots(Lot 1, Block 3 or Lot 10, Block 2)until the Morin's subdivide when a permanent would then be required. The southerly private street(Lakeway Drive at the end of the cul-de-sac) is proposed to serve Lots Lake Lucy Estates May 20, 1998 Page 6 5 and 6, Block 2. However, Lot 6 is a very large lot and has the potential for further subdivision. The Fire Marshal may also require an acceptable turnaround if the driveway exceeds 150 feet in length. This will require additional grading and tree loss on Lot 6 if it is further subdivided in the future. The plans propose to fill up to four feet of material in this area to prepare the house pads and private driveway(Lakeway Drive). This is also necessary to provide adequate cover for the sanitary sewer to service these lots. In addition, fill material will give the ability to create lookout or walkout-type dwellings without further grading towards the wetland. The grading plan needs to incorporate dwelling types along with garage and first floor and lowest floor elevations for staff to review. Without this information it is relatively difficult to determine full grading impacts on the project. Custom-graded lots will require detailed grading (with two- foot existing and proposed contours), drainage,tree removal and erosion control plans at time of building permit application for City staff to review and approve. Building pad locations designated on the custom-graded lots are seldom used. The house configuration and soil factors will govern the location. Therefore, tree canopy loss may or may not be accurate and in most instances it is not. Tree loss is generally 10%to 15%higher due to construction activities outside of the home and generally impacts trees 20 feet away from the foundation. Retaining walls are a practical way of minimizing grading and tree loss. The applicant should be aware that retaining walls in excess of four feet in height will required building permits and engineered drawings. A soils report was prepared for the applicant by Braun Intertec. A summary of the results of the soils evaluation indicated soil borings typically encountered a one to four-foot layer of topsoil at the surface. Below the topsoil most of the borings encountered glacially deposited soils. Layers of alluvial deposits were encountered above the glacial till into the boring. Groundwater was encountered at four of the six boring locations. At these locations groundwater was encountered 4 to 11 feet below the surface or above elevation 950.5 to 965.5. The soil report also supplied recommendations which indicated the topsoil, the alluvial soil and some soft glacial soils found in the borings are considered unsuitable for supportive proposed loads due to high organic content and/or associated compressibility under fill and building loads. To prepare for construction the report recommended removal of these soils and any existing fill in the building or oversized area. In the streets,the soil should be removed at least three feet below the proposed roadway subgrade elevation. The excavations would then be backfilled with engineered fill as needed to achieve the building and/or street subgrade elevation. The report also indicated the natural clays on the site will be suitable for reuse as fill but will require drying to achieve compaction requirements. The City's typical street section requires a two-foot sand subcut underneath the standard pavement section in order to prepare the street in accordance with the City's typical urban street section. Typically,with the soil conditions on hilly terrain,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. Storm sewer and tree fencing needs to be denoted on the final grading and drainage plans prior to final plat approval. Typically, in a development like this the developer is also the builder. However, in this case staff is unsure whether the actual developer will be building the homes. Past experience has educated staff to make things as clear as possible with regards to grading and tree removal limits in the conditions of approval. Apparently,communication is lost between the developer and builder and prospective home buyer at time of building permit application. The City has envisioned one way of constructing a home on the lot; however, the prospective home buyer has another and seldom Lake Lucy Estates May 20, 1998 Page 7 do they correspond. Therefore, staff is recommending that tree removal grading limits should be specifically addressed on each of the custom-graded lots so as any prospective home buyers will know exactly what they are able to do to the lot. 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. UTILITIES Municipal sanitary sewer service is proposed to be extended from the Coey parcel which was 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. The sanitary sewer has been extended through the Pointe Lake Lucy development and deadended at the property just east of the development(Morin's). The exact alignment of the sewer line has been staked in the field up to the Morin's property previously by staff and the property owner. The alignment minimizes tree loss and impacts to the wetlands and Morin's property. The applicant will need to adjust their plans to incorporate this alignment. In addition,the necessary utility easement for this extension needs to be acquired in order to proceed with the project. Without the sewer, this project should be considered premature for development. A condition has been added in the staff report that preliminary and final plat approval will be contingent upon sanitary sewer being extended through the Morin's property. At the time the Morins subdivide their parcel and connections are made to the sewer line,the applicant will be entitled to a refund of a portion of the connection charge the City will impose at time of building permit. Staff recommends that the individual sewer and water service be field verified prior to construction to determine a location on each lot which minimizes tree loss. The applicant should also be advised that,based on the soils report, there may be some areas of unsuitable material where the pipe will need to be place on pilings or significant subgrade correction performed prior to installation of the pipe. Municipal water service is available to the site from Lake Lucy Road. The plans propose on extending water service throughout the development. Detailed street and utility 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 latest edition of the Standard Specifications and Detail Plates. Final construction plans and specifications will need to be submitted to the City a minimum of three weeks prior to final plat consideration for staff review and City Council formal 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 final plat conditions of approval and installation of the public improvements. The development contains two existing home sites (Tichy and Christensen). Both of these home sites 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 4,Block 3. Both have on-site well and septic systems that will need to be abandoned in accordance with the City and State building codes in conjunction with this development. The well and septic on Lot 1, Block 2 will have to be abandoned in conjunction i Lake Lucy Estates May 20, 1998 Page 8 with demolition of the home. 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 need to be designed and constructed to service the Morin's property as well as the properties to the west of the site and north of Lake Lucy Road. The applicant has not provided sewer and water extension west of the development. Staff will be reviewing the need for providing utility service to the adjacent parcels. The applicant shall be responsible for extending sanitary sewer service west of the site and north of Lake Lucy Road in a location determined by staff. 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. The applicant is proposing to dedicate on the final plat an additional 7 feet of right-of-way to meet the City's design criteria along Lake Lucy Road. Street right-of-way on the public street within the plat has been reduced from the 60-foot requirement to 50 feet wide in an effort to reduce grading and tree loss. Staff has evaluated this compromise and believes the reduced right-of-way may be warranted except for the cul-de-sac diameter. The plans are also incorporating the use of private driveways to service portions of the development and adjacent parcels. City ordinance provides for up to four homes to be serviced off a private driveway. A turnaround acceptable to the City's Fire Marshal will also have to be provided. The private driveways will reduce impacts to the wetlands and minimize tree loss versus a public street. Staff believes the use of a private driveway to service Lots 5 and 6, Block 2 may be warranted to reduce impacts to the area. The construction of a public street in this area would destroy the natural features. In addition,Lots 5 and 6,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. If a public street was required to serve Lots 5 and 6, Block 2 there would be only two lots created at the end on Lot 6, Block 2 due to setbacks from the street and wetlands. Lot 5, Block 2 would not meet code requirements. Therefore, an argument could be made for not allowing Lot 6, Block 2 to future subdivide. Another private street is proposed to service three lots (Lots 9 and 10, Block 2 and Lot 1,Block 3) and the Morin's parcel to the east. The Morin's and staff have previously 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 Morin's are not in favor of the turnaround at this time, a temporary turnaround could be developed on Lot 10,Block 2 or Lot 1, Block 3 until the Morin's are ready to subdivide. Future access was also considered for the parcel west of the development(Randall). The Randall's parcel currently gains access from Lake Lucy Road via a long gravel driveway. Part of the driveway is actually located within the proposed subdivision through Lots 1, 2 and 3,Block 1. The Randall's driveway access onto Lake Lucy Road is across from Yosemite. This intersection Lake Lucy Estates May 20, 1998 Page 9 has substandard sight distance which makes it difficult to safely turn to and from the property. Eventually, when the Randall parcel further subdivides, staff will recommend that the driveway access onto Lake Lucy Road be eliminated and the driveway be relocated to access Lakeway Lane. It appears the Randall 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 1 to provide future access to the site. Lot 1, Block 2 will also be accessed from this street. A sign will be required on the barricades as wells as a condition in the development contract indicating that "Lakeway Lane may be extended in the future". Staff has reviewed the street grades and alignment and believes,with the exception of the cul-de- sac, no further modifications are available to minimize tree loss and grading. These changes were also discussed in the grading portion of this report, i.e. retaining wall in the northeast corner of Lakeway Drive and Lakeway Lane and revise cul-de-sac configuration and relocation of stormwater pond. All lots are proposed to access the interior streets and not directly onto Lake Lucy Road. The existing driveway to Lot 4, Block 3 is proposed to be relocated to Lakeway Drive. This will result in the necessity to change their street address. 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. Street grades range from 1%to 10%which exceeds City Ordinance. City Ordinance requires street grades to be between 0.75%and 7%. Staff believes that a 10%street grade may be warranted in this situation to better conform to existing terrain and minimize grading and tree loss. However, staff is recommending that a 3%or less landing minimum length of 75 feet be designed at the intersection of Lake Lucy Road and Lakeway Drive to provide adequate sight lines and acceleration onto Lake Lucy Road. Staff believes that this can be easily accomplished. MISCELLANEOUS The final plat will need to dedicate a 60-foot radius on the cul-de-sac. In addition, drainage and utility easements shall be dedicated over the stormwater pond and any utility improvements which lie outside the City's road right-of-way. The minimum easement width shall be 20 feet wide depending on the depth and location of the utility or stormwater pond basin. WETLANDS There are 2 wetlands delineated on-site and they are as follows: 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 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 Lake Lucy Estates May 20, 1998 Page 10 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. Wetland Buffers The City wetland ordinances requires a buffer strip and buffer strip monumentation along wetlands. The buffer strip width required for natural wetlands is 10 to 30 feet with a minimum average width of 20 feet. The principal structure setback for these wetlands is 40 feet measured from the outside edge of the buffer strip. The applicant has proposed a buffer strip of 10 feet along Lots 10,9,8,7 and 4. Lot 6 is shown with a thirty foot buffer to accomplish the 20 ft. average and lot 5 has a sharp transition from 30 to 10 feet. City staff would recommend that the lot 5 buffer be adjusted so that there is a smoother transition along the Lot 5 property line. Such sharp transitions in buffer zones have resulted in buffer removal in the past. Lake Access There are three lots on this site that would meet the 90 foot width requirement for access to Lake Lucy. However,to access the lake, each of these properties must impact the wetland to get to the Lake. In the extreme case Lot 6 must go through 350 feet of wetland to reach the ordinary high water level. Staff recommends that all of these lots access the lake at the point of least impact to the wetland on a shared dock. The location of this dock would be on Lot 6. SURFACE WATER MANAGEMENT PLAN(SWMP) 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, (or$9,184 for the 11.48 acres) for single-family residential developments may be waived if the applicant provides water quality treatment according to the City's SWMP standards. To receive this credit the applicant must provide the City with plans for a stormwater quality pond 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. PARK DEDICATION Full park and trail fees shall be collected per city ordinance in lieu of land acquisition and/or trail construction. The existing house located on Lot 4, Block 3, is exempt from these fees. If the Lake Lucy Estates May 20, 1998 Page 11 home is demolished and a new residence is built,the site would then be subject to these fees. TREE PRESERVATION/LANDSCAPING Tree canopy coverage and preservation calculations for the Lake Lucy Estates development are as follows: Total upland area 11.17 ac or 486,565 SF Total canopy area (excluding wetlands) 9.51 ac or 414,256 SF Baseline canopy coverage 85% Minimum canopy coverage allowed 55% or 6.14 ac/267,610 SF Proposed tree removal 42% or 4.67 ac/203,425 SF Proposed tree preservation 43% or 4.84 ac/210,830 SF Developer does not meet minimum canopy coverage allowed,therefore the difference is multiplied by 1.2 to calculate the required replacement plantings. Difference in canopy coverage 56,780 SF Multiplier 1.2 Total replacement 68,136 SF Total number of trees to be planted 63 trees A replacement planting plan must be submitted to the city for approval. Included in the plan shall be location, species and size of replacements. All replacements must meet minimum size requirements. The applicant has requested that replacement plantings vary in size, from seedling to the 2 %i minimum required by ordinance. Staff supports the request for trees planted in excess of the 63 required. Of the 63 trees required, staff recommends the minimum required size is upheld. The applicant's tree canopy preservation and replacement calculations stated that 19 trees were to be replaced. This erroneous calculation was based on incorrect removal and preservation percentages. The applicant has prepared a solid and comprehensive forest management plan for the site. Tree survey results, woodland condition and replacement plantings plans are all covered in detail. The applicant appears prepared to properly handle the development of the property and its woodlands. The plan states that trees will be and have been assessed for preservation based on their condition, location, age,and species. This technique will serve to avoid the mistakes made by developers in wooded areas in the past where inappropriate trees are preserved only to die once construction has finished. Staff recommends tree removal limits for each lot be established as shown on the grading and tree preservation plans submitted by the applicant. It appears a 20 foot removal limit from the building pad would be coincide with tree removal shown on the applicants' plans. Tree loss/preservation for the development is comparable to the loss associated with the previous Byrne application. The current applicant has not preserved significantly any more or less of the woodlands than the previous proposal. What this applicant has done,however, is invested time Lake Lucy Estates May 20, 1998 Page 12 and effort into preparing a forest management plan for the site and the future development. 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. This plan should show the type and size of trees proposed to be planted as well as the location of any berms along Lake Lucy Road.

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. 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 is attempting to minimize impact on the property and staff is making recommendations that should be incorporated into the plan. 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. 5. The proposed subdivision will not cause environmental damage; Lake Lucy Estates May 20, 1998 Page 14 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. 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 April 24, 1998, for the following: a. A 20 foot front yard setback for Lot 7 and 10, Block 2, and Lot 3, Block 4. 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 6, Block 2. 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 Lake Lucy Estates May 20, 1998 Page 15 city finds the following conditions to exist: 1. The prevailing development pattern makes it not feasible 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, 9,and 10, Block 2, and Lot 1,Block 3. Private streets will minimize impact on the vegetation and preserve site grades. Lakeway Court will serve 5 lots,however,we believe in this case a variance is appropriate. BUILDING OFFICIAL COMMENTS Dwelling Types. The type of dwelling is necessary to enable the Inspections Division and Engineering Department to perform a satisfactory plan review of the structure at the time of building permit issuance. For the same reason, proposed lowest level floor elevation, entry floor elevation (not top of block)and garage floor elevation is required to be indicated on the proposed pad location. Standard designations (FLO or RLO, R, SE, SEWO, TU, WO) must be shown for proposed dwelling types. These standard designations lessen the chance for errors during the plan review process. The memo explaining these designations is enclosed. Demolition Permits. Existing structures on the property which will be demolished will require a demolition permit. Proof of well abandonment must be furnished to the City and a permit for septic system abandonment must be obtained and the septic system abandoned prior to issuance of a demolition permit. A house moving permit is required if a structure is to be moved to another location within the City. House moving permits must be approved by the City Council. A road use permit is required to move a structure over City roads. Retaining Walls. Retaining walls over 48" high from the base of their footings require a building permit and inspections. RECOMMENDATION Staff recommends the Planning Commission adopt the following motion: "The Planning Commission recommends approval of rezoning 16.40 acres of property zoned RR, Rural Residential to RSF, Residential Single Family(95-1 REZ); Preliminary plat(95-3 SUB) to subdivide 16.40 Acres into 17 single family lots,with variances(a 20 foot front yard setback for Lots 7 and 10,Block 2, and Lot 3, Block 3, a 10 percent street grade and a 50 foot wide right-of- way, Five homes accessing via a private street, and a 10 foot side yard setback for the west side of Lot 6, Block 2),Lake Lucy Estates,as shown in plans dated April 24, 1998, with the following conditions: Lake Lucy Estates May 20, 1998 Page 16 1.

Those changes include custom grading wooded lots, increasing the street grade (Lakeway Drive) up to 10% to conform better with the existing ground contours which results in less grading, adjusting building pad locations and/or changing dwelling types to conform with existing ground. However, staff believes there still are modifications that can be completed to improve the overall site and reduce grading and tree loss. One such change would be to shorten the cul-de-sac and shift it easterly approximately 20 feet. In addition,relocate the proposed stormwater pond to the west side of the cul-de-sac and lower the cul-de- sac grade a minimum of one foot. This will result in saving significant oak trees which lie on the easterly side of the proposed cul-de-sac within the proposed stormwater basin.The west of the cul-de-sac is basically void of vegetation and may add an amenity to the proposed dwelling. One drawback of relocating the stormwater pond would be the lowest floor elevation on Lot 4, Block 2 would be affected. The City and Watershed both have a restriction that requires a lowest floor elevation of a building adjacent to a stormwater pond or wetland be two feet above the high water level. The grading plan also proposes custom-graded lots in the wooded areas with the exception of Lots 7 through 10, Block 2 where mass grading will occur to prepare house pads and Lakeway Court. The sanitary sewer is proposed along Lakeway Court which would take a swath a minimum of 40 feet wide due to the depth of the sewer regardless. Staff has learned from previous developments that front yard trees over time eventually die due to construction impacts. Therefore, staff is comfortable with the proposed grading of these lots in The City of Chanhassen.A growing community with clean lakes,quality schools,a charming downtown,thriving businesses,and beautiful parks.A great place to live,work,and play. Sharmin Al-Jaff Lake Lucy Estates Preliminary Plat Review May 14, 1998 Page 2 an effort to minimize tree impacts on the back portion of these lots. As you will note, the grading plan incorporates grading outside of the 50-foot wide right-of- way. City Ordinance requires a subdivision to dedicate 60-foot wide right-of-ways and 60-foot wide radius in a cul-de-sac. The plans are proposing a 50-foot wide right-of-way and 50-foot wide radius cul-de-sac. Staff believes that a 60-foot wide right-of-way could be dedicated without impacting too many of the lots; however, given the very steep terrain on the northerly half of the project, the additional right-of-way would increase the setbacks for the homes thus creating additional fill for driveways and dwellings which, in turn, would affect existing tree canopy coverage. Therefore, staff is comfortable with permitting a 50-foot wide right-of- way; however, the cul-de-sac will need to be 60-foot radius to provide adequate room for snow storage and utility improvements. According to the grading plan it appears the site will be short on material. Staff anticipates the applicant will need to import material to develop the site. The applicant will need to supply the City with a haul route and traffic control plan for review and approval prior to site grading commencing. In an effort to reduce grading and tree loss, staff is recommending that a retaining wall be incorporated in the northwest corner of Lakeway Drive and Lakeway Lane. In addition, retaining walls could be further extended along private driveways to minimize grading and tree loss as well. Lakeway Court also needs to provide for a temporary turnaround acceptable to the City's Fire Marshal. The temporary turnaround could be created on one of the lots (Lot 1, Block 3 or Lot 10,Block 2) until the Morin's subdivide when a permanent would then be required. The southerly private street(Lakeway Drive at the end of the cul-de-sac) is proposed to serve Lots 5 and 6, Block 2. However, Lot 6 is a very large lot and has the potential for further subdivision. The Fire Marshal may also require an acceptable turnaround if the driveway exceeds 150 feet in length. This will require additional grading and tree loss on Lot 6 if it is further subdivided in the future. The plans propose to fill up to four feet of material in this area to prepare the house pads and private driveway (Lakeway Drive). This is also necessary to provide adequate cover for the sanitary sewer to service these lots. In addition, fill material will give the ability to create lookout or walkout-type dwellings without further grading towards the wetland. Sharmin Al-Jaff Lake Lucy Estates Preliminary Plat Review May 14, 1998 Page 3 The grading plan needs to incorporate dwelling types along with garage and first floor and lowest floor elevations for staff to review. Without this information it is relatively difficult to determine full grading impacts on the project. Custom- graded lots will require detailed grading (with two-foot existing and proposed contours), drainage, tree removal and erosion control plans at time of building permit application for City staff to review and approve. Building pad locations designated on the custom-graded lots are seldom used. The house configuration and soil factors will govern the location. Therefore, tree canopy loss may or may not be accurate and in most instances it is not. Tree loss is generally 10% to 15% higher due to construction activities outside of the home and generally impacts trees 20 feet away from the foundation. Retaining walls are a practical way of minimizing grading and tree loss. The applicant should be aware that retaining walls in excess of four feet in height will required building permits and engineered drawings. A soils report was prepared for the applicant by Braun Intertec. A summary of the results of the soils evaluation indicated soil borings typically encountered a one to four-foot layer of topsoil at the surface. Below the topsoil most of the borings encountered glacially deposited soils. Layers of alluvial deposits were encountered above the glacial till into the boring. Groundwater was encountered at four of the six boring locations. At these locations groundwater was encountered 4 to 11 feet below the surface or above elevation 950.5 to 965.5. The soil report also supplied recommendations which indicated the topsoil,the alluvial soil and some soft glacial soils found in the borings are considered unsuitable for supportive proposed loads due to high organic content and/or associated compressibility under fill and building loads. To prepare for construction the report recommended removal of these soils and any existing fill in the building or oversized area. In the streets, the soil should be removed at least three feet below the proposed roadway subgrade elevation. The excavations would then be backfilled with engineered fill as needed to achieve the building and/or street subgrade elevation. The report also indicated the natural clays on the site will be suitable for reuse as fill but will require drying to achieve compaction requirements. The City's typical street section requires a two-foot sand subcut underneath the standard pavement section in order to prepare the street in accordance with the City's typical urban street section. Typically,with the soil conditions on hilly terrain, 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 Sharmin Al-Jaff Lake Lucy Estates Preliminary Plat Review May 14, 1998 Page 4 an acceptable means of controlling sump pump discharge from the homes as well as improve the street subgrade. Storm sewer and tree fencing needs to be denoted on the final grading and drainage plans prior to final plat approval. Typically,in a development like this the developer is also the builder. However, in this case staff is unsure whether the actual developer will be building the homes. Past experience has educated staff to make things as clear as possible with regards to grading and tree removal limits in the conditions of approval. Apparently, communication is lost between the developer and builder and prospective home buyer at time of building permit application. The City has envisioned one way of constructing a home on the lot; however, the prospective home buyer has another and seldom do they correspond. Therefore, staff is recommending that tree removal grading limits should be specifically addressed on each of the custom- graded lots so as any prospective home buyers will know exactly what they are able to do to the lot. 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. UTILITIES Municipal sanitary sewer service is proposed to be extended from the Coey parcel which was 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. The sanitary sewer has been extended through the Pointe Lake Lucy development and deadended at the property just east of the development(Morin's). The exact alignment of the sewer line has been staked in the field up to the Morin's property previously by staff and the property owner. The alignment minimizes tree loss and impacts to the wetlands and Morin's property. The applicant will need to adjust their plans to incorporate this Sharmin Al-Jaff Lake Lucy Estates Preliminary Plat Review May 14, 1998 Page 5 alignment. In addition, the necessary utility easement for this extension needs to be acquired in order to proceed with the project. Without the sewer, this project should be considered premature for development. A condition has been added in the staff report that preliminary and final plat approval will be contingent upon sanitary sewer being extended through the Morin's property. At the time the Morins subdivide their parcel and connections are made to the sewer line,the applicant will be entitled to a refund of a portion of the connection charge the City will impose at time of building permit. Staff recommends that the individual sewer and water service be field verified prior to construction to determine a location on each lot which minimizes tree loss. The applicant should also be advised that, based on the soils report, there may be some areas of unsuitable material where the pipe will need to be place on pilings or significant subgrade correction performed prior to installation of the pipe. Municipal water service is available to the site from Lake Lucy Road. The plans propose on extending water service throughout the development. Detailed street and utility 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 latest edition of the Standard Specifications and Detail Plates. Final construction plans and specifications will need to be submitted to the City a minimum of three weeks prior to final plat consideration for staff review and City Council formal 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 final plat conditions of approval and installation of the public improvements. The development contains two existing home sites (Tichy and Christensen). Both of these home sites 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 4, Block 3. Both have on-site well and septic systems that will need to be abandoned in accordance with the City and State building codes in conjunction with this development. The well and septic on Lot 1, Block 2 will have to be abandoned in conjunction with demolition of the home. 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. • Sharmin Al-Jaff Lake Lucy Estates Preliminary Plat Review May 14, 1998 Page 6 The sanitary sewer to serve this development will need to be designed and constructed to service the Morin's property as well as the properties to the west of the site and north of Lake Lucy Road. The applicant has not provided sewer and water extension west of the development. Staff will be reviewing the need for providing utility service to the adjacent parcels. The applicant shall be responsible for extending sanitary sewer service west of the site and north of Lake Lucy Road in a location determined by staff. 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. The applicant is proposing to dedicate on the final plat an additional 7 feet of right-of-way to meet the City's design criteria along Lake Lucy Road. Street right-of-way on the public street within the plat has been reduced from the 60-foot requirement to 50 feet wide in an effort to reduce grading and tree loss. Staff has evaluated this compromise and believes the reduced right-of-way may be warranted except for the cul-de-sac diameter. The plans are also incorporating the use of private driveways to service portions of the development and adjacent parcels. City ordinance provides for up to four homes to be serviced off a private driveway. A turnaround acceptable to the City's Fire Marshal will also have to be provided. The private driveways will reduce impacts to the wetlands and minimize tree loss versus a public street. Staff believes the use of a private driveway to service Lots 5 and 6, Block 2 may be warranted to reduce impacts to the area. The construction of a public street in this area would destroy the natural features. In addition, Lots 5 and 6,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. If a public street was required to serve Lots 5 and 6, Block 2 there would be only two lots created at the end on Lot 6, Block 2 due to setbacks from the street and wetlands. Lot 5, Block 2 would not meet code requirements. Therefore, an argument could be made for not allowing Lot 6, Block 2 to future subdivide. Another private street is proposed to service three lots (Lots 9 and 10, Block 2 and Lot 1,Block 3) and the Morin's parcel to the east. The Morin's and staff have previously 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 Sharmin Al-Jaff Lake Lucy Estates Preliminary Plat Review May 14, 1998 Page 7 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 Morin's are not in favor of the turnaround at this time, a temporary turnaround could be developed on Lot 10, Block 2 or Lot 1, Block 3 until the Morin's are ready to subdivide. Future access was also considered for the parcel west of the development (Randall). The Randall's parcel currently gains access from Lake Lucy Road via a long gravel driveway. Part of the driveway is actually located within the proposed subdivision through Lots 1, 2 and 3, Block 1. The Randall's driveway access onto 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 Randall parcel further subdivides, staff will recommend that the driveway access onto Lake Lucy Road be eliminated and the driveway be relocated to access Lakeway Lane. It appears the Randall 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 1 to provide future access to the site. Lot 1, Block 2 will also be accessed from this street. A sign will be required on the barricades as wells as a condition in the development contract indicating that "Lakeway Lane may be extended in the future". Staff has reviewed the street grades and alignment and believes, with the exception of the cul-de-sac, no further modifications are available to minimize tree loss and grading. These changes were also discussed in the grading portion of this report, i.e. retaining wall in the northeast corner of Lakeway Drive and Lakeway Lane and revise cul-de-sac configuration and relocation of stormwater pond. All lots are proposed to access the interior streets and not directly onto Lake Lucy Road. The existing driveway to Lot 4, Block 3 is proposed to be relocated to Lakeway Drive. This will result in the necessity to change their street address. 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. Street grades range from 1% to 10% which exceeds City Ordinance. City Ordinance requires street grades to be between 0.75% and 7%. Staff believes that Sharmin Al-Jaff Lake Lucy Estates Preliminary Plat Review May 14, 1998 Page 8 a 10% street grade may be warranted in this situation to better conform to existing terrain and minimize grading and tree loss. However, staff is recommending that a 3% or less landing minimum length of 75 feet be designed at the intersection of Lake Lucy Road and Lakeway Drive to provide adequate sight lines and acceleration onto Lake Lucy Road. Staff believes that this can be easily accomplished. MISCELLANEOUS The final plat will need to dedicate a 60-foot radius on the cul-de-sac. In addition, drainage and utility easements shall be dedicated over the stormwater pond and any utility improvements which lie outside the City's road right-of-way. The minimum easement width shall be 20 feet wide depending on the depth and location of the utility or stormwater pond basin. RECOMMENDED CONDITIONS OF APPROVAL 1. The applicant will need to develop a sediment and erosion control plan in accordance with the City's Best Management Practice Handbook and the Surface Water Management Plan requirements for new developments. The plan shall be submitted to the City for review and formal approval. Type III erosion control fence shall be used adjacent to the wetlands and Type 1 erosion control fence shall be used adjacent the grading limits. 2. All areas disturbed as a result of construction activities shall be immediately restored with seed and disc-mulched or wood-fiber blanket or sod within two weeks of completion of each activity in accordance with the City's Best Management Practice Handbook. 3. All utility and street improvements shall be constructed in accordance with the latest edition of the City's Standard Specifications and Detail Plates. Detailed street and utility plans and specifications shall be submitted for staff review and City Council approval three weeks prior to final plat consideration. 4. Wetland buffer areas shall be surveyed and staked in accordance with the City's wetland ordinance. The City will install wetland buffer edge signs before accepting the utilities and will charge the applicant$20 per sign. Sharmin Al-Jaff Lake Lucy Estates Preliminary Plat Review May 14, 1998 Page 9 5. The applicant shall provide detailed storm sewer calculations for 10-year and 100-year storm events and provide ponding calculations for stormwater ponds in accordance with the City's Surface Water Management Plan for the City Engineer to review and approve prior to final plat approval. The applicant shall provide detailed pre-developed and post developed stormwater calculations for 100-year storm events and normal water level and high water level calculations in existing basins, created basins, and or creeks. Individual storm sewer calculations between each catch basin segment will also be required to determine if sufficient catch basins are being utilized. In addition,water quality ponding design calculations shall be based on Walker's Pondnet model. 6. The applicant shall enter into a development contract with the City and provide the necessary financial security to guarantee compliance with the terms of the development contract. 7. The applicant shall apply for and obtain permits from the appropriate regulatory agencies, i.e. Carver County,Watershed District, Metropolitan Waste Control Commission, Health Department,Minnesota Pollution Control Agency, Minnesota Department of Natural Resources, Army Corps of Engineers and Minnesota Department of Transportation and comply with their conditions of approval. 8. The appropriate drainage and utility easements should be dedicated on the final plat for all utilities and ponding areas lying outside the right-of-way. The easement width shall be a minimum of 20 feet wide. Consideration shall also be given for access for maintenance of the ponding areas. A 40- foot wide drainage and utility easement will be required over the utilities located within Lakeway Court. 9. No berming, retaining walls or landscaping will be allowed within the right- of-way. 10. The lowest floor elevation of all buildings adjacent to the wetlands or storm water ponds shall be a minimum of 2 feet above the 100-year high water level. 11. A water quality pond shall be provided on the west side of the cul-de-sac to pretreat runoff prior to discharging into the wetlands.

The stormwater pond shall be designed and constructed with a 75%phosphorus removal efficiently. A landscape plan providing upland and wetland plants to naturally blend the pond into the surroundings is recommended. 12. Existing wells and/or septic systems on site will have to be properly abandoned in accordance to City and Minnesota Department of Health codes/regulations. The existing home (Tichy) on Lot 4, Block 3 shall be connected to the City's sanitary sewer system within 30 days after the system becomes operational. Connection to City water is not required unless the well on Lot 4, Block 3 fails. 13. The proposed single-family residential development of 11.48 developable acres is responsible for a water quantity connection charge of$22,730. These fees are payable to the City prior to the City filing the final plat. The water quality fees will be waived if the applicant provides for on-site stormwater treatment. 14. The applicant shall report to the City Engineer the location of any drain tiles found during construction and shall re-locate or abandon the drain tile as directed by the City Engineer. The construction plans shall include a drain tile system behind the curbs and gutters on those lots which are not adjacent to a wetland or storm pond. 15. All lots shall take direct access to the interior street system and not Lake Lucy Road. Lot 4, Block 3 shall relocate their driveway from Lake Lucy Road to Lakeway Drive. In addition, the street address for this lot shall be changed accordingly. 16. Lots 1 through 3, Block 1, Lots 1 through 3, Block 2, and Lots 1 through 3,Block 3 shall be custom graded at time of building permit issuance. A detailed grading (with two-foot contours), drainage, tree removal and erosion control plan shall be submitted with the building permit application for review and approval by the City engineer prior to issuance of a building permit for the lot. Sharmin Al-Jaff Lake Lucy Estates Preliminary Plat Review May 14, 1998 Page 11 17. The grading,drainage,and construction plans shall be revised incorporating the following changes that conform better with the existing grades and minimize grading and tree loss: a) Tree protection fencing. b) Retaining wall along the northeast corner of Lakeway Lane and Lakeway Drive to reduce grading and minimize tree loss. c) Shorten and lower cul-de-sac and increase radius to 60 feet. d) Relocate stormwater pond to west side of cul-de-sac. e) Provide "Y" or "T" temporary turnaround on Lakeway Court. f) Denote dwelling type on all lots including garage,first and lowest floor elevation. g) Label height of retaining walls. h) Provide drain tile behind the curb for those lots not adjacent to wetlands or stormwater pond. i) Design private driveway (Lakeway Drive)to drain partially back to cul-de-sac. j) Add outlet control structure to pond. k) Revise sanitary sewer alignment through Morin's parcel and provide sanitary sewer service to parcel to the west per staff. 18. Preliminary and final plat approval shall be contingent upon sanitary sewer service being extended to the plat from the Coey property (Point Lake Lucy)to this site and the applicant obtaining a drainage and utility easement from the Morins. 19. All private streets shall be designed and constructed in accordance to City Ordinance No. 209 and a turnaround acceptable to the City's Fire Marshal.

Analysis: Dwelling Types. The type of dwelling is necessary to enable the Inspections Division and Engineering Department to perform a satisfactory plan review of the structure at the time of building permit issuance. For the same reason, proposed lowest level floor elevation, entry floor elevation (not top of block) and garage floor elevation is required to be indicated on the proposed pad location. Standard designations (FLO or RLO, R, SE, SEWO, TU, WO) must be shown for proposed dwelling types.These standard designations lessen the chance for errors during the plan review process. The memo explaining these designations is enclosed. Demolition Permits. Existing structures on the property which will be demolished will require a demolition permit. Proof of well abandonment must be furnished to the City and a permit for septic system abandonment must be obtained and the septic system abandoned prior to issuance of a demolition permit. A house moving permit is required if a structure is to be moved to another location within the City. House moving permits must be approved by the City Council. A road use permit is required to move a structure over City roads. Retaining Walls. Retaining walls over 48"high from the base of their footings require a building permit and inspections. Recommendations: The following conditions should be added to the conditions of approval. 1. Revise the preliminary grading & erosion control plan to show the proposed dwelling pads with standard designations and indicate the lowest level floor, entry level floor and garage floor elevations. This should be done prior to final plat approval. 2. Obtain demolition permits. This should be done prior to any grading on the property. 3.

LAKE LUCY ESTATES Chanhassen, Minnesota by Contractor Property Developers Company April 24, 1998 PROPOSAL This project is proposing to develop 17 single family lots on 16.40 acres. The project requires the following approvals: 1. Rezoning of property zoned RR, Rural Residential to RSF, Residential Single Family. 2. Preliminary Plat/Subdivision of the property. 3. Variances to allow 20 foot front yard setbacks on 3 lots, a 10%street grade,a 50' wide right- of-way,a 50' radius cul-de-sac R.O.W.width,and five homes to be served via a private street. SITE CONDITIONS Land Use The 16.40 acre site(14.56 acres located above the OHW level) is located south of Lake Lucy Road, north of Lake Lucy: and southeast of the intersection of Yosemite Avenue and Lake Lucy Road. The site currently is made up of two lots with two existing single family homes. Surrounding land uses include the Shadow Ridge Subdivision to the north(RSF, Residential Single Family), Lake Lucy to the south, and RR, Rural Residential land use to the east and west. The City of Chanhassen 2000 land use plan has identified the subject property as well as the properties located to the east and west as Residential- Low density(net density range 1.2-4 units per acre). Natural Environment Site topography ranges from elevation 956.1 at Lake Lucy to a high point of 1036,adjacent to Lake Lucy Road. Much of the change in elevation and steep slopes occur on the northern half of the site. The southern half of the site gradually slopes to Lake Lucy. The site contains two wetlands that have a combined total of approximately 3.39 acres that are located on the site. The wetland that is located along the east property line is characterized as an inland shallow fresh marsh. Approximately 1.79 acres of the wetland is located on the property. The second wetland that is found to the south is part of the natural wetland complex that borders the Lake Lucy shoreline,above the OHWL of Lake Lucy. Approximately 1.60 acres of the wetland is located on the property. The majority of the site is wooded. The most prevalent tree species found on the site is Ash which makes up approximately 30%of the total tree canopy. The next most prevalent tree species is the Box Elder(16.3%)followed by Oak(13.7%), Linden (8.4%), Elm (7.2%), Hickory (5.8%), Aspen (5.5%), and Pin Cherry(5.3%). Apple,Cottonwood, Hackberry, Ironwood and Willow percentages are below 5%of the total tree inventory. CITY of CHPNHASSEN APR 2 41998 _ ��CFT There is a significant area made up of invasive Buckthorn/Amur maple that is found on the lower portion of the site that is included in the tree canopy(9.51 acres-April 7, 1998)that has been determined by the City. In addition,there are areas of diseased Oak and other canopy areas that have been impacted by part use of off-road recreation vehicles. These areas reduce the quality of the forested area and are discussed in greater detail an attached forest management plan prepared for the development. Site Access and Utilities The proposed site access is from Lake Lucy Road. Lake Lucy Road is classified as a collector street in the City's Comprehensive Plan. The existing two properties that make up the site are currently unsewered and have private septic sewer systems. An 8"sanitary sewer stub exists approximately 200' away from the eastern property line of the subject site. Municipal water service is available to the site from Lake Lucy Road. No storm sewer system currents exists on site. The majority of the storm water drains naturally from Lake Lucy Drive to the wetland on the eastern border of the proposed development. PROPOSED DEVELOPMENT Rezoning The proponent is requesting a rezoning to RSF, Residential Single Family District and subdivide the property into 17 lots. As previously stated,this request for rezoning is in compliance with the Comprehensive Plan and the City of Chanhassen 2000 Land Use Plan which identifies the property as Residential Low Density(Net Density 1.2 -4 units per acre). The subdivision of 17 lots will establish a density of 1.16 units per acre. Variances The proponent is requesting variances to allow 20' front yard setbacks on 3 lots, 10% street grade, a 50' wide R.O.W. and 50' cul-de-sac R.O.W. width and 5 homes to be served by a private street. These variances are requested to reduce grading and subsequent tree lots,due to the particular physical surroundings, shape and topographical conditions of the land. SITE ACCESS Site access will come from Lake Lucy Drive. All of the proposed lots will be served by Lakeway Drive and private drives that access it. None of the lots will have direct lot access to Lake Lucy Drive. Lakeway Drive is proposed as an ±850' long cul-de-sac with a 50' wide right-of-way and a 50' radius for the right-of-way at the turnaround. A 50' public street right-of-way and roadway stub will be established by this development which allows for future development of the property to the west(Willis Property). One of the lots(Lot 1, Block 2)will have lot access from this stub which is to be named Lakeway Lane. UTILITIES AND DRAINAGE Sanitary sewer is available at the west boundary of the Point Lake Lucy subdivision. This will be extended weterly across the Morin property to the site. An 18 inch watermain is located in Lake Lucy Road. A lateral line will extend into the site and provide opportunity for future looping to the west. Storm water runoff will be collected into a storm sewer system and be directed to a stormwater treatment pond at the end of the cul-de-sac and next to a wetland The proposed development utilizes private streets that access Lakeway Drive and serve 5 lots. The private drive will have a right-of-way width of 30', and pavement width of 20'. Lakeway Drive will serve Lots 5,6 of Block 2, and Lakeway Court serves Lots 9, 10 of Block 2 and Lot 1 of Block 3. The Moran parcel to the east of the development may be further subdivided in the future by others into 2 additional lots and be served by Lakeway Court. The site grading is intended to minimize site alteration,preserve the natural features of the site and yet allow for the creation of lots. Use of retaining walls has been minimized to the greatest extent possible yet used in a few key areas. Tree preservation was a prime concern. Canopy removal has been minimized when possible and prudent to do so. Areas at quality,healthy trees were given the greatest priority. Areas of invasive, exotic species and older,diseased trees were considered expendable. The attached Forestry Manage Program explains the existing forest condition,plan to reverse the current forest degradation and intent to help re-establish a healthy, native forest environment.

Westwood Professional Services, Inc. (612)937-5150 FOREST MANAGEMENT PLAN LAKE LUCY ESTATES, CHANHASSEN, MINNESOTA April, 1998 PROJECT PURPOSE, DESCRIPTION, AND WOODLAND IMPACTS The Lake Lucy Estates is a proposed single family residential development located on approximately 14.56 acres with 11.17 acres of upland in Chanhassen,Minnesota. The development proposes to provide 17 single family residences. The site is located in the S '/2 of Section 2,T 116 N,R 23 W,City of Chanhassen,Carver County,Minnesota (Exhibit 1). The property is bordered on the south by Lake Lucy,on the north by Lake Lucy Road and on the east and west by private residences. The total area of canopy on the property is approximately 9.51 acres(per City calculation 4/22/98)or 85%of the site. The baseline canopy coverage(minimum coverage to remain after development)is 55%or 5.23 acres. The proposed impacts are 4.67 acres(49%)canopy removal and 4.84 acres(51%)of canopy remaining. This results in 0.39 acres of canopy that need to be replaced. Replacement requirements are calculated by multiplying the replacement acres by 1.2. This results in 0.78 acres of canopy to be replaced. Replacement trees are required at a rate of 40 trees per 1 acre of removed canopy;therefore,the required number of replacement trees for the proposed impact is 19 trees. However,the project proposes to actually provide more trees and shrubs in association with forest under-planting and landscaping efforts. We propose a variety of sizes from seedlings(underplanting)to 2 '/2 inch diameter. The quantity and/or value will be at least equivalent to the required replacement. WOODLAND OVERVIEW The woodland on this property is quite diverse in terms of species,size,and condition. The forest is comprised of approximately 30%ash, 16%box elder, 14%oak, 8%linden,7%elm, 6%hickory,6%aspen,5%cherry,and scattered ironwood,cottonwood,apple,willow,spruce,cedar and hackberry. In general,the oaks represent the trees of largest diameter and apparent canopy dominance;however,the ash and box elder appear better suited for larger areas of the site which experience periods of wet conditions. Significant areas of recent ash and box elder establishment exist on the property. There is a moderate buckthorn problem in the understory of the forest and shrubs and saplings dominate in areas adjacent to Lake Lucy in the southern part of the property. Tree Survey Results Woodland areas were inventoried in connection with a previous project proposal. This data was evaluated and additional site visits were made to collect more information and confirm the accuracy of the available tree survey. As the survey and subsequent site visits indicate,the woodland on this property is in a stage of transition. A large portion of the oaks in the dominant canopy are in a declining state of health due to over maturity,wet conditions, and Armillaria root rot. The dieback of the oaks is slowly opening up the forest establishment of ash,box elder and buckthorn. Ash and box elder are better suited for the wet conditions occurring on portions of the site and buckthorn is a very aggressive,invasive exotic. There are two pockets of oaks occurring on the property. One pocket is located in the southeast corner of the site and is comprised of small diameter(<10")oaks. The second pocket is located in the central portion of the site and is comprised of large diameter(>18")oaks. The small diameter oak pocket is in fairly good health while the large diameter pocket shows significant signs of decline and dieback due to various pathogens including Armillaria root rot. Westwood Professional Services, Inc. (612)937-5150 Lake Lucy Estates Page 2 Forest Management Plan April 1998 These observations suggest that preservation efforts within this woodland developed in support of activities such as construction be focused on the small diameter pocket of oaks as well as any individual large diameter oaks not exhibiting serious dieback symptoms. It is also suggested that restoration efforts be focused on establishing desirable tree regeneration and understory composition in the area of oak and canopy dieback. DESIGNATED WOODLAND AREAS Location and size of Replacement/Forestation tree planting areas The required number of replacement trees for the proposed 0.39 acres of excess impact is 19 trees. However,the project proposes to actually provide more trees and shrubs in association with forest under-planting and landscaping efforts This site represents a unique opportunity for the developer,the City of Chanhassen,and the neighborhood surrounding Lucy Lake. The woodland on this property shows a history of productive hardwood growth and development. The level of productivity has declined in recent years dues to dieback of the overstory due to disease and decadence and a lack of desirable,viable tree regeneration in the understory to fill the resulting gaps. Other minor impacts have combined to start a transitional trend in this woodland. Impacts such as moderate to heavy recreation use and trail development,historic orchard management,and moderately wet conditions in association with Lake Lucy and the wetland have created conditions less suitable for oak dominance and which facilitate buckthorn invasion. If left to develop without disturbance,it is highly probably that this woodland would slowly transform from a mature oak woodland to a mixed lowland hardwood stand to a ash and box elder dominated forest with significant areas of buckthorn brush and a understory consisting almost exclusively of invasive exotic species. The opportunity for the parties involved is to restore this woodland and reverse the transition. It is requested that the City support the developer's proposal to do reforestation and replacement planting on the site using planting materials averaging less than 2.5 inches in diameter. The developer proposes to do some understory planting using small diameter seedlings and saplings. These understory plantings will consist of native trees and shrubs that represent high quality species suited to the site and providing more of the natural diversity of a Minnesota forest with greater ecosystem functionality. It is the desire of the developer that they understory plantings be established as advanced regeneration to help insure that oak and other hardwoods will remain a part of the forest canopy even as the current specimens dieback. It is also the intention of the developer to reestablish shrub diversity on this site as desirable understory material,wildlife habitat,water quality protection,and competition for the invading common buckthorn. By properly designing,planting,protecting,maintaining,and managing the proposed understory planting,it is the intention of the developer to help restore this woodland to a more functional example of a native Minnesota hardwood forest.

(612)937-5150 Lake Lucy Estates Page 6 Forest Management Plan April 1998 METHODS OF TREE PROTECTION Tree protection methods to be implemented on the Lake Lucy Estates site follow recommendations and guidelines set forth in Protecting Trees from Construction Damage,Minnesota Extension Service Publication#FO-6135-S (Miller,et.al. 1995,). As grading limits are staked in the field,the trees anticipated to be impacted by these activities will be assessed and marked for removal or preservation as determined by their location,general health,condition,and potential to present a hazard in an area with increased levels of human occupation. Location of all protective fencing Protective fencing will be installed as recommended per Minnesota Extension Service Publication#FO-6135-S (Miller,et.al. 1995)or as deemed necessary by contractors and site developers. Protective fencing will be established in accordance with the above cited recommendations for all trees in proximity to disturbance activities and marked in the field as feasible and desirable to preserve. Special construction methods to be utilized Special construction methods are not anticipated at this time. However,if situations develop recommendations will be followed as outlined in Minnesota Extension Service Publication#FO-6135-S(Miller,et.al. 1995)or as deemed necessary by contractors and site developers. Location of all retaining walls Retaining walls to be established on the property will be identified on site plans and built in such a manner as to reliably protect the tree resource by protecting as much of the critical root radius as is feasible. Statement explaining why replacement trees are necessary Site development plans will include activities which necessitate the removal of some trees. These development activities are necessary to meet project goals and provide housing to meet local market demands. The establishment of ponding on the site will protect the quality of the local water resource and help prevent any water level increases on the site which would further reduce the suitability of the site as oak woodland habitat. • -Rationale for selection of replacement/forestation trees Trees to be used in replacement and forestation were selected primarily on the basis of suitability to site conditions. Only native species will be used and predominantly species already present on the site to help retain and restore the historic forest composition on the site. High quality hardwoods such as hackberry,basswood,cherry,and ironwood were selected for their superior growth form and desirability as both forest and boulevard trees. Bicolor oak were selected in addition to other oak species already occurring on the site because of their reduced susceptibility to oak wilt and their greater tolerance of the moderately wet habitat occurring in planting areas adjacent to Lake Lucy. By maintaining a variety of oak species on the site there is a reduced likelihood of any single pathogen causing an epidemic in the forest. Sugar maple and birch are both native species which are a natural component of mature oak woodlands with moderately wet pockets. The coniferous species,including black spruce and white pine,were selected to be used in areas were higher levels of screening and view preservation are required. It is suggested that some of the replacement requirements be met through the use of innovative planting designs and materials. One of the desires of the project proposer is to design a planting plan which actual improves the current woodland in terms of regenerative capacity,dominance of high-quality species in both the canopy and understory, Westwood Professional Services, Inc. (612)937-5150 Lake Lucy Estates Page 7 Forest Management Plan April 1998 and overall canopy health. It is suggested that these goals can be met by removal of diseased oaks during construction,and establishing replacement trees to consist in part of understory plantings of tree seedlings. The goal of project designers is to establish tree species such as various oaks,maples and ironwood in the understory to help combat the buckthorn invasion and provide replacement canopy for future oak dieback. Installation design would include the establishment of protective measures such as plastic tubing or mesh to prevent rodent,rabbit and deer damage to the seedlings;however,seedlings would be planted in such numbers as to allow some loss without significantly impacting the ability of surviving seedlings to meet project goals. CONTROL OF EXOTIC SPECIES It is recognized that buckthorn occurs on the property in such a degree as to limit the establishment and regeneration of desirable,native shrub and tree species. It is the desire of the developer to determine a method of effective and economic control of buckthorn. At this time such a method has not been identified for the property. It will be difficult to effectively,efficiently,and economically control buckthorn on this site because of the fairly large area of woodland that would need to be treated,proximity to water resources,and the abundance of a buckthorn seed source in the immediate vicinity. It is not recommended that buckthom controls be initiated until all or the vast majority of site disturbance and proposed landscaping has been completed. Attempts to control buckthorn before project completion have a reduced likelihood of success due to the presence of appropriate seedbeds for buckthorn invasion. Project developers will continue to investigate new buckthorn controls that are being developed and their applicability for treatment of this property. It is anticipated that development of some areas will remove buckthorn from these areas and quick establishment of sod and other ground covers will limit buckthom reestablishment. It is also anticipated the understory restoration efforts will establish some more desirable seed sources in the area for native species and also provide competition to slow the invasion of common buckthorn. The extent of buckthom on the site will be reinvestigated during and following the various phases of development. Westwood Professional Services, Inc.

The intention of this visit was to assess the accuracy and acceptability of the wetland delineation and assess the condition and composition of the wooded portion of the property. A wetland delineation was prepared for the property by Peterson Environmental Consulting,Inc. The final wetland report submitted to the City of Chanhassen is dated March 22, 1995. The project manager was Scott Krych. Conversations with the Water Resources Coordinator for the City of Chanhassen indicate that the City still accepts this delineation and will not require a new delineation be performed at this time. During the site review on April 1, 1998, several wetland delineation flags were observed and appeared to correspond consistently and correctly with the wetland edge as was evidenced by distinct contrasts in vegetation types, topography,and hydrology. Before examining the woodland resource on the property, several sources of information were reviewed. In 1995,a tree survey was completed for the property. The survey recorded a diverse mix of tree species including willow, ash,linden(basswood),box elder,red oak,red cedar,elm,hackberry,hickory,black oak, scotch pine, and ironwood. Conversations with the forester for the City of Chanhassen and a memo dated March 23, 1995 dispute the accuracy of the black oak observations. Previous documentation concerning the woodland on this property disagrees on the extent of canopy coverage.The various calculations are as follows: Canopy Percent of Total Canopy to Canopy Total Canopy Total Date/Author of Coverage Upland' be Removed Remaining to Replace Replacement Calculation (acres) (acres) (acres) (acres) Trees 9.11 79% 5.28 3.83 1.74 70 Applicant, 3/23/95 8.35 73% 5.89 2.46 3.38 135 City, 3/23/95 7.45 N/A 3.58 3.87 1.63 65 Unknown,5/17/95 Observations on the property indicate that the density of the canopy varies greatly throughout the property. Also, the forest is criss-crossed with trails which reduces the amount of area effectively covered by tree ' Upland Area was calculated as 11.48 acres(Applicant,March 23, 1995). Memorandum - CPDC April 6, 1998 Page 2 canopy. Rough estimates indicate that the basal area in the well-stocked areas of the woodland ranges from about 100 square feet per acre in a small pocket of mature oak to as high as 130 square feet in another area with smaller diameter ash. Previous observations of these woods, as reported in the various documents, appear to have neglected mention of the condition of these woods in terms of disease or insect stress. The general condition of this woodland is difficult to access because it varies greatly throughout. The "best"area in terms of desirable species which are healthy and presumably vigorously growing is located in a narrowing between the wetland to the north and Lake Lucy to the south, in the southeast corner of the property. Another pocket of woodland located in a diagonal band between the wetland and the southernmost residence on the property exhibits characteristics of a mature oak woodland; however, this pocket also shows signs of disease and insect stress. Areas between and surrounding these two pockets are largely populated with small diameter box elder, ash, and aspen. The woodland situated between the wetland and Lake Lucy is of primary importance because it consists generally of oak and basswood of moderately small diameter(6-12"). There is less indication of the diseases evidenced in other parts of the property. These trees are presumably vigorously growing and healthy enough to withstand moderate disturbance. The woodland located between the wetland and the residence is of interest because it is the one area on the site containing large diameter oaks. Most canopy trees in this area are over 20" in diameter. If one just looks at this area of woodland in a horizontal fashion, it is aesthetically pleasing. However, by looking over one's head, it is quickly noted that the crowns of many of these majestic oaks are plagued with dead branches and broken limbs. The oaks in this area vary greatly in their condition and degree of health. There are some individuals which have little or no crown dieback,but the majority have significant decay and low probability of long-term survival or successful regeneration. The selection of viable trees to be preserved in this area will be difficult. The woodlands located between these two pockets are an indication of what the entire forested area may convert to if or when the oak canopy thins due to decadence and disease. It is feasible to presume that this forest is currently in a state of transition. Ecologically speaking, there are several scenarios to consider about the history and potential future of this woodland. Firstly, this is a mesic site with abundant water and clayey soils. These are atypical conditions for an oak dominated forest. Secondly, oak on the site is highly unlikely to remain a major component in the canopy through the next generation of trees. Thirdly, the most likely successors to oak in the canopy are ash,box elder and aspen. Lastly, it is likely that buckthorn will continue to increase its presence in the understory. Therefore, if left alone this woodland will slowly but surely convert from a oak forest to a shrubby ash and box elder woods with a buckthorn understory. Observations were made of several diseases and other damaging agents operating in this woodland. These agents and the species most affected are listed below: • Armillaria mellea (shoestring root rot) (oak) • termites (oak, large diameter trees) • Eutypella canker(maple) • bacterial wetwood (elm) • Rhizosphaera needlecast(spruce) • smooth patch(oak) • white pine blister rust(white pine) Westwood Professional Services, Inc. (612)937-5150 Memorandum-CPDC April 6, 1998 Page 3 Some of these diseases, such as smooth patch and bacterial wetwood, are highly unlikely to cause tree mortality and are generally undesirable only because of the aesthetic degradation they cause. Rhizosphaera needlecast observed on the property was occurring on large spruce in the front yards of current residences. Through properly applied and timed pruning and spraying, this problem can also be limited to the loss of only a few lower branches. The white pine blister rust was observed on yard trees of the adjacent property. This observation does not directly affect the trees currently occurring on the property,but is important to note when selecting new species to be planted in the area. The most serious indications of forest decline in this woodlot are the termites and shoestring root rot. The termites were observed in the base of a large,nearly dead oak tree. The presence of these insects indicates that some of the trees on the property that may appear structurally sound and stable may in fact have severely degraded support in the main stem and base. These trees may be highly susceptible to wind throw and pose a hazard in a setting with high levels of human activity. These trees also have large, dead limbs in their crowns which could cause damage or be hazardous to prune. Trees infested with termites are unlikely to survive even low or moderate levels of disturbance within the critical root zone. Evidence of shoestring root rot(Armillaria mellea)was found throughout the wooded portion of the property. Shoestring root rot is a fungus that attacks the "circulatory system" of the tree. Outbreaks are most common on both red and white oaks, but ash and maple can also be infected. The fungus grows through the soil and attacks the roots of stressed trees. The fungus causes girdling of the stem, root and shoot dieback, and even death if site conditions are not changed. The oak species on the property show the most signs of root rot infection. There is extensive crown dieback occurring. Large, dead branches are in the crowns of most large diameter(>20") oaks on the property. It is probably that these oaks are succumbing to root rot because they are being stressed by the flooded or waterlogged conditions on much of the property. The fact that the oaks are being so heavily affected by a stress related fungus is an indication that this species is ill-suited for the conditions occurring on this property. Conversations with the pathology professor at the University of Minnesota indicate that it is unlikely that the oaks will survive the root rot if the stress factor is not alleviated. Conversations with the DNR Area Hydrologist indicate that the recent development in the Lake Lucy area may be increasing runoff levels to the wetland and lake and causing water levels to slowly increase. These possible changes in water table could be closely related to the stress exhibited by the oaks on the property and the appearance of woodland transition. If a trend of water level increase is suspected, it expected that the site will continue to become less suitable for continuation as oak habitat. The continuing and increasing water stress will keep the remaining oaks in a state of stress and highly susceptible to two-lined chestnut borers and root rot. It is evidenced that this area was once grazed. This landuse facilitated the invasion of exotic, noxious plants such as common buckthorn. Also the criss-crossing trails through the woodland have probably assisted the introduction of buckthorn and exposure of viable seedbeds. The invasion of buckthorn in the understory functions to limit the viability of tree regeneration in the forest floor. „� Westwood Professional Services, Inc.

The intention of this review was to assess the grading limits and tree preservation potential for the project There are several rules of thumb when selecting trees to be preserved during construction`; 1. Favor preservation of smaller diameter trees; 2. Favor preservation of species best suited to site; 3. Favor species less susceptible to any diseases or insect problems on the site; 4. Favor a variety of species; and 5. Favor groups rather than individuals. In short, "Favor the best; Remove the rest". There is little point to making extravagant efforts to protect trees during construction if actual tree survival is highly unlikely. The money would be better spent purchasing high quality planting material to be established following construction. Because the woodland on this site has a diverse mix of species, it is important to note that not all trees have the same level of tolerance for disturbance in the root zone. For open grow trees, such as those located in the front lawns or backyards of the current residences, the dripline or edge of the tree canopy is a fair indication of the "protected root zone". For trees grown in a forested or closed canopy condition, the protected root zone is best calculated on the basis of diameter(dbh). The protected root zone for forest trees is equal to the dbh, in inches, multiplied by 1.5 which gives an answer which should be interpreted as a radius in feet. Examples include: Protected Root Zones for Example DBHs. dbh (inches) Protected Root Zone (feet) 6 9 12 18 18 27 24 36 36 54 Much of the information in this memo is taken from the Minnesota Extension Service publication FO-6135-S, entitled Protecting Trees from Construction Damage(Miller, et al. 1995). Memorandum- CPDC April 8, 1998 Page 2 The protected root zone is the area where disturbance should be minimized to the extent possible. The amount of disturbance that a tree will tolerate before becoming stressed and increasingly susceptible to pathogens varies by species and condition. Some trees are highly sensitive to disturbance while some healthy trees of disturbance tolerant species have been known to survive after losing up to 50% of their root systems. Examples of tolerance levels for tree species occurring on this site include; Root Severance Tolerance Levels for Various Tree Species. Tolerant Intermediate Sensitive cedar spruce ironwood ash hickory white oak aspen basswood black oak box elder cherry cottonwood elm hackberry maple red oak Compaction/Flooding Tolerance Levels for Various Tree Species. Tolerant Intermediate Sensitive cedar elm aspen spruce hackberry cherry ash hickory ironwood box elder basswood cottonwood red oak maple white oak black oak If a species is considered "tolerant" it may be possible to disturb up to 25% of the area within the protected root zone. For"intermediate" species, it is recommended that no disturbance occur within the protected root zone, and for"sensitive" species, it may be necessary to restrict construction levels and activities even beyond the protected root zone. Another thing to consider during construction is relocation of smaller diameter trees. Healthy, small trees of intermediate or tolerant species may survive transplanting. On this site, it is not recommended that excessive efforts be made to preserve large diameter oaks located in low lying areas adjacent to the wetland. This is the area of the site with the most evidence of root rot infection of the oaks. Also, oak is ill-suited for the wet conditions along the wetland. Beyond simply selecting trees to be preserved during and following construction, it will be important to minimize all activities in the areas of selected trees. Driving and parking heavy machinery within the protected root zone of these trees can not be allowed. The soil compaction that would result from such activities would increase root stress to the point of negating any preservation efforts. The rule of thumb on this site during construction will have to be "if the machine is in the shade, it's in the wrong place". Up to 95% of a tree's root system is located in the upper three feet of soil. Any rutting, compaction, excavation, or trenching in this area has a large, negative impact on the likelihood of tree survival. r Westwood Professional Services, Inc. (612)937-5150 MEMORANDUM TO: Sharmin Al-Jaff, Planner II FROM: Jill Kimsal,Forestry Intern DATE:March 23, 1995 SUBJ: Tree Inventory and Preservation, Point Lake Lucy West, Michael Byrne The applicant submitted a tree inventory survey and canopy coverage calculations for the development. The inventory failed to list all trees 12 inches in diameter and larger. Upon inspection of the site, staff found many trees that failed to be shown on the inventory. Therefore, the submitted inventory does not present the true image of the woodlands on site. Before approval of the development is granted, a revised tree inventory denoting all trees 12 inches and larger on site must be submitted. The site is heavily wooded with a wide range of species and age classes. Large, mature oaks exist throughout the site as well as thick stands of young ironwoods, aspens, ash, elms, and cottonwoods. There is a range of ages in all species on site implying that the woodlands are fertile and productive. One interesting find on the tree survey is the existence of a 24" Black Oak. While this tree is the most common upland oak in the eastern United States, its presence in Chanhassen is unique since the range of this species only extends to the three most southeastern counties in Minnesota. The tree is nearly identical in appearance to red and pin oaks, common to this area, but differs from them in the shape of the acorn. On inspection of the site, no acorns could be found to support or refute the claim. In the absence of the City's verification, however, the benefit of the doubt should be granted and measures taken to plan the preservation of such a rare and unique tree. Development in the southern portion as specified in plans would not be an option. Alternatives must be considered that would not allow development within a distance of 1 1/2 times the dripline from the tree. According to applicant, existing tree canopy covers 9.11 acres out of the total 11.48 of upland acres. Therefore the existing canopy coverage would be 79%. The City's tree protection ordinance states that 46%of the existing canopy remain or 4.19 acres. The developer plans on removing 5. 28 acres of canopy during construction which would leave only 3.83 acres. The 1.45 acres that are lost are multiplied by 1.2 as specified in the tree preservation ordinance to calculate the reforestation requirements. A total of 1.74 acres or approximately 70 trees would have to be planted to meet city standards. Staff calculation of the site figured canopy coverage at 73%, or 8.35 acres. The developer is required to maintain 46%, 5.28 acres, canopy coverage after development. Canopy removal due to development was calculated to be 5.89 acres, leaving only 2.46 acres remaining. Replacement requirements would be for 1.2 times 2.82 acres for a total reforestation of 3.38 acres, or 135 trees. Since calculations of canopy coverage and removal differ significantly, applicant will need to verify calculations. Alignment of the city sewer lines is recommended along the northern edge of the wetland on the east side of the development. This route can be aligned so as to avoid a number of large trees and to take advantage of an existing cleared path. The site will be irrevocably changed by development. Because of extensive grading few, if any, trees will be able to be saved within the grading limits. Only those on the outer edges will be left relatively unaffected. The applicant has proposed boulder walls to preserve some of the larger trees on site. Applicant will need to show elevations of all trees that are planned to be preserved. Mature trees with grade changes of more than 4 feet inside 50%or more of their dripline will not be recommended for preservation. So little of the original grades and environment will be retained that the future health of the remaining trees within grading limits must be carefully planned. Lake Lucy Estates May 17, 1995 Page 12 TREE PRESERVATION/LANDSCAPING The 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 removal of canopy coverage has not changed significantly. Where applicable, homes have been moved either closer or farther from the street in order to avoid individual or stands of 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 Lots 9 and 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 insure 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 are usually 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. Whether or not it will live because of the shift depends on the treatment it receives during construction, as is the case with all preserved trees in the development. It's important that preservation of trees in the development does not become a tree by tree issue at the time of construction. Trees in front yards are much more difficult to protect during construction as well as trees near cuts or fills. To avoid tree conflicts and attempt to save as many trees as possible, a tree removal plan must be clearly identified. Preservation areas are one alternative, they provide coverage of large wooded areas, but also allow for significant removal and prove difficult to regulate after the Certificate of Occupancy is issued. Another alternative is a numbered inventory which authorizes tree removal by number prior to construction. This is valuable for saving trees that would otherwise fall outside of a preservation area but are not within the construction limits. An encumbrance is that excellent judgement and foresight must be used in order to realistically decide which trees should be saved. This can be a difficult task. 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.

Periodic occurrences of decline and death of oaks over widespread xz.t,•�: s areas have been rccorded since 1900. These outbreaks, variously „,,' •.' ; named Oak decline, Oak dieback, or oak mortality, are caused by a complex interaction of environmental stresses and pests and given the name oak decline. `~" =f tt��k�, tr. • Hosts h .;� . I, Although the most frequent outbreaks of oak decline have been in "w , yc southern New England, the Middle Atlantic States, and the � n-. • Southeastern States, the disease has occurred throughout the range of oak in both forest and urban situations (fig. 1). It is not limited to any ;* �' g•= - r' : one species or species group. Outbreaks have been most frequent and , t -trm-,;+ severe among red (Quercus rubra), scarlet (Q. coccinea), pin (Q. �'- _-=' s ti' palustris), and black oak (Q. velutina) in the red oak group and ,.;. ' . among white (Q. alba)and chestnut oak(Q.prinus) in the white oak ,.`A' ;"'''''•. group. Other important tree species that have suffered serious declines include ash, birch, beech, and maple. http://winow.ncfes.umn.edulfidl-oakdcline'oakdecline.htm 1/30/9S FIDL - Oak Decline Page 2 of 6 ' i `� ,- i n �A —-- i wtr-.1 3-, .4.,0 iit I ,f, ' 2..........4--_, - ....._ A...:Ift. __.__ 1 4 s.

I I T ille 1 C o,r-:�,0„y _� --L Q OQ\ ry 1 Disease Progression Trees are weakened by environmental stresses such as drought, waterlogging, or frost or by pests such as defoliating or sucking insects. Weakened trees are then invaded and killed by insects and diseases that cannot successfully attack healthy trees. Usually the progression of decline is slow, occurring over several years. Trees affected by oak decline show a general and progressive dying back from the tips of the branches. (See cover.) Other symptoms include production of chlorotic, dwarfed, and sparse _ foliage; development of sprouts on main branches and stem; and premature autumn leaf color and leaf drop. Often, growth is reduced before the appearance of symptoms. The amount of food stored as starch is reduced, especially in the roots. The Initiating stress factors associated most frequently with oak decline are drought, frost injury, or insect defoliation. Trees on ridge tops and in wet areas suffer most severely from drought. Frost often affects trees growing in valleys and frost pockets. Defoliated trees that refoliate the same season may exhibit dieback symptoms the next year. Other factors such as leaf diseases and soils that are waterlogged, compacted, or shallow have occasionally been implicated in oak decline. Waterlogging is especally important in the heavier clay soils of the Midwest. Stress facton may be more frequent and severe in urban forests, where trees are often subjected to disturbances assoiated with human activities. These stress factors often weaken trees so much that they succumb, sometimes suddenly, to the root killing and girdling actions of insects and diseases. The two major pests associated with oak decline are Armillaria mellea (Vahl: Fr.), a root disease commonly called armillaria root rot, and Agrilus bilineatus (Weber), the twolined chestnut borer. http://willow.ncfes.umn.edu'fidl-oakdcline'oakdecline.htm 1/30/9S FIDL - Oak Decline Page 3 cel - • r�1i . .ti ' s liti j1fAs. .Yi.:;W•. . • rv" ,. <!41/ 6.

' produces rootlike structures -rhizomorphs-which grow through the ` soil and over the surface of healthy tree roots (fig.2). When trees are r _ stressed, chemical changes occurring in the roots allow the fungus to . infect and kill them. Continued infection will eventually result in girdling of the large buttress roots and root collar(fig. 3).This,in Figure 5-Adult of the turn, kills the tree.

The combined actions of the borer in girdling action. the stem and the fungus in the roots can bring about rapid decline and death. As dieback and reduced growth continue, larger branches die and form the characteristic stag-headed crown (fig. 8). Foliage is mainly limited to sprouts on the larger branches and main stem. http: v.illow.ncles.umn.edu/fidl-oakdcline'oakdechne.htm 1/30/9S FIDL - Oak Decline Page 4 of 6 Figure 7-Four --•: Figure 8-A •-._ larval stages of A. zz.' stag-headed oak with bilineatus. -�- rt,'�,�1,.

Indeed, stress, if sufficiently severe or prolonged, can result in tree mortality. However, the continued decline and death of stressed oaks usually results from lethal attacks by armillaria root rot and twolined chestnut borers. Final symptoms of oak decline primarily reflect the root killing and girdling effects of these organisms. In attacked trees, leaves sometimes fail to develop in the spring or wilt shortly alter budbreak; sometimes they wilt or brown suddenly in the latter part of the growing season. A characteristic of Oak decline is that it may develop suddenly on many trees in the area affected by the initiating stress factor. Within the affected areas. howevcr, decline and mortality occur in patterns, which my reflect the intensity and seveity of the stress, the distribution of the hosts, the aggressiveness of armillaria root rot, and the abundance of twolined chestnut borers, coupled with site features such as poor or excessive soil drainage and frost pockets (fig. 9). :y 1: .. -��-_�' �✓, _ • ,- �,p� Yom.�.t '.�..;�Yiy�� ''� ':=-;.,r;i M��," y 'frog:'„-•:_.:�•.?;,•%..97F X3: "' ' '''- ' ^moi `� ''' t" Figure 9-Pockets of oak 71:-...t...10'7%-...1„..,-;0,,,,F, 'l am .,-. ,, mortality resulting from the . ._ - :ti. . .''711. 1-i5A' 7-.:11 ti I► -_f� ''y3 � „.."... 1 ,..,c1 ,,... vi,:ri,-7.*:.,1 �Ytrialf` ��� }`�'� }yy ;:moi interaction of stress, insects, .

For example, symptoms only on white oaks or only on red oaks might suggest that preferential insect defoliation was the cause. Frost may be implicated if damage is limited to trees growing in depressions or valley bottoms. Symptom development can also indicate the stage of decline and approximate beginning of the problem. The age of bole sprouts and patterns of radial and terminal growth can be used to estimate the date of the events that triggered their development. Although some trees die soon after being stresed, others may not succumb for 5 years or more. The timng of peak mortality, if known, can give some indication of when the stress may have occurred. For example, mortaity is usually highest 2 years after heavy insect defoliation. Such tree growth information, when coupled with an analysis of weather and forest records, can be used to develop a composite picture of the cause and stage of the oak decline problem. http:-1«•illo v.ncfes.umn.edu'fid!-oakdcline'oakdecline.htm 1/30/95 FIDL- Oak Decline Page 5 of In the diagnosis of oak decline, it is important to determine if stress factors are associated with the specific problem and, at the same time, to rule out the involvement of primary pathogenic organisms such as the oak wilt fungus. Oak wilt caused by the fungus Ceratocystis fagacearum (Bretz)Hunt has been reported from the Lake States east to Pennsylvania and south to Terxas. It has not been found in New England,New York, or New Jersey. All oak species are susceptible to the fungus. Red oaks are more susceptible than white oaks. Differences Between Oak Decline and Oak Wilt Oak Decline. Within both red and white oak groups, oak decline is characterined by(1) progressive terminal branch dieback; (2)branch and bole sprout and staghead development; (3) sudden foliage wilt and browning,but no leaf drop; (4) fans and rhizomorphs of A. mellea often present beneath bark of roots and root collars on dying trees; (5) galleries and exit holes of A. bilineatus often present in stems of dying or dead trees (6) decline found throughout the range of oak; (7)mortality related to site features, tree stress, and affects of insets and diseases; and (8) tree mortality peaking 2 to 5 years following stress. Oak wilt in the red oak group. In the red oak group, oak wilt is characterized by(1) leaf wilt and drop over entire crown, (2) leaf portions bronzing or browning, (3)rapid tree mortality, (4) no progressive branch dieback, (5) formation and then death of short-lived sprouts in the season after infection, and (6)vascular streakikg (dark longitudinal streaks) found occasionally in outer growth ring. Oak wilt in the white oak group. In the white oak group, oak wilt is characterized by(1) leaf wilt on scattered branches that die back and form sprouts and(2)vascular streaking common in outer growth ring. Some trees may continue to wilt and die back until all branches and sprouts are dead, yet other trees may survive. In both red and white oaks, armillaria root rot and twolined chestnut borers are not usually associated with trees dying of oak wilt In oak wilt, unlike oak decline, isolated trees or small pockets of trees can be diseased with no history of environmental stress. The infection centers are not related to site features. Laboratory diagnosis is usually required to conclusively identify oak wilt-diseased trees. Control The unique relationship of cause and affect and patterns of distribution of oak decline must be considered, and control efforts should focus on reducing or preventing the predisposing stree factors. In the forest, factors such as drought and frost cannot be controlled. However, management can reduce their effects. Thinning can reduce competition for moisture and nutrients and promote better physiological condition of the remaining trees. Silvicultural practices designed to encourage species best adapted to the site can help reduce the effects of drought or frost. Removal of weak and dying trees may also reduce or delay population buildup of the twolined chestnut borer. Stress from insect defoliation can be reduced or eliminated in high-value forest stands by spraying the trees with insecticides. Landowners can get specific information on insecticides available for control from cooperative extension agents or local forestry officials. In urban sites, additional control measures are feasible. Moisture shortages can be alleviated by watering, mulching to reduce competition from sod, and reducing or avoiding soil compaction. Trees can also be treated to control sucking and defoliating insects and disease http://willow.ncfes.umn.edu/fidl-oakdcline/oakdecline.htm 1/30/98 FIDL- Oak Decline Page 6 of 6 organisms that cause defoliation. Nutritional deficiencies can be corrected by fertilizing. These practices eliminate some forms of stress and promote good physiological condition. Oak dellne is Initiated by stresses,which can disappear before effects are manifested.A systematic evaluation of the problem can usually reveal the initiating factors and the agents responsible for mortality. Practices to promote good tree health can reduce the potential impacts of damage by oak decline.

Zastrow and Trenten L. Martyr ABSTRACT. In May 1987, 2-0 red oak (Quercus rubra) seedlings were planted in two separate trials and protected with 1.2 meter plastic tree shelters on a variety of forested sites and vegetative cover types. Additional 2-0 red oak seedlings with plastic tree shelters were planted in similar fashion in May 1988. Initial survival of the planted stock was excellent, but decreased dramatically over time as overhead competition increased. In May 1989, 1-0 red oak seedlings were established in an old field situation. Three treatments were compared; protection of the seedling with a 1.2 meter plastic tree shelter, protection of the seedling with a rigid plastic mesh, and no protection of the seedling as a control situation. After two years, survival is significantly higher in both of the protected seedlings and height growth is significantly higher in the plastic tree shelters. INTRODUCTION The establishment and maintenance of red oak (Quercus rubra) on private and public lands is vital for wildlife habitat and forest products. The specific ecological natural-regeneration requirements of red oak has led to numerous research trials and stand prescriptions to supplement natural regeneration of red oak (Johnson et. al. 1984; Johnson 1984; Johnson 1985; Lorimer 1989). The continual lack of consistent success in natural and artificial regeneration of red oak has been attributed to slow initial seedling growth (Lorimer 1989), acorn predation (Auchmoody 1990), seedling browse by deer and small mammals (Hannah 1987), and competition of surrounding vegetation (Johnson et. al. 1989). This lack of regeneration success in red oak has provided emphasis for other artificial regeneration trials in the Lake States. One of these alternatives is the use of plastic tree shelters. The use of tree shelters by Tuley (1983) in Great Britain identified a technique to establish and protect oak seedlings. Follow-up studies in Great Britain identified the following benefits of tree shelters: increased survival and height growth, protection from browsing, easy location of planted stock, effectiveness of herbicide application to target species, and creation of a greenhouse effect within the shelter (Potter 1988). A disadvantage of tree shelters is the cost associated with the purchase and establishment in forest plantings (Jamil et. al. 1991). An applied Lake States study in Michigan documented an increased height growth of red oak in shelters (Lantagne et. al. 1991).

Presented at The Oak Resource in the Upper Midwest Conference,Winona,MN,Junc 3-6, 1991. The Oak Resource in the Upper Midwest 199 Tree shelters are made of a translucent, polypropylene plastic, 1.2 m high and 8-12 cm wide in diameter. These shelters are designed to last five to seven years under field conditions. Wooden stakes, preferably white oak (Quercus alba) approximately 1.2 meter long are utilized to anchor the shelter. A plastic fastener is used to attach the shelter to the stake, after the stake is driven in the ground next to a seedling. This paper presents observations and results of tree shelter trials established on several public lands in central Wisconsin. METHODS TRIAL #1 In 1937, 240 2-0 red oak seedlings were hand planted in the Mead Wildlife Area in central Wisconsin. The intent of this trial was to observe red oak seedling responses in shelters compared to nonsheltered seedlings in a variety of vegetative covertypes. Observational plots of ten sheltered seedlings and ten nonsheltered seedlings were established on twelve different sites within the property. The sites were generally Rietbrock silt loams, and Meadland loams, and habitat types were generally Acer-Hydrophyllum (Kotar et. al. 1988). The twelve sites demonstrated a range of vegetative covertypes including a sod field, fresh aspen (Populus grandidenta and Populus tremuloides) clearcuts, established one to two year old aspen reproduction stands, and several brush openings created by older herbicide treatments. Seedlings planted without a tree shelter were marked with a flagged metal stake. Initial survival was measured after the first growing season in September 1987, and in September 1990. TRIAL #2 In 1937, 196 2-0 red oak seedlings with tree shelters were hand planted on a site on the Marathon County Forest, central Wisconsin. This trial was established as an underplanting of a red oak stand. The intent of this trial was to observe sheltered trees under a high shade crown controlled canopy. The stand was treated with a shelterwood harvest in 1986 with a 70 percent crown closure residual. The site is a Mosinee sandy loam and the habitat type is Acer-Quercus-Viburnum (Kotar et. al. 1938). Survival was measured during the third growing season of June 1989 and in September 1990. TRIAL #3 In 1938, 200 sheltered 2-0 red oak seedlings were hand planted in the Mead Wildlife Area in fresh aspen clearcuts. The intent of this trial was to observe initial sheltered oak seedling development with aspen competition. Incorporation of a future oak component within aspen stands is desirable both from a forestry and wildlife management objective. A total of six observational plots were established with plots ranging in size from 24 planted sheltered seedlings to 60 planted sheltered seedlings. The sites were primarily Rietbrock silt loams and habitat types were Acer-Hydrophyllum, (Kotar et. al. 1988). In September 1990, after the third growing season, survival was assessed. . , . 200 The Oak Resource in the Upper Mid;zst TRIAL #4 In May 1989, 450 1-0 red oak seedlings were hand planted in Council Grounds State Park, in central Wisconsin. The intent of this trial was to compare survival and height growth of sheltered seedlings and nonsheltered seedlings in an old field situation. The planting design contained ten completely randomized replications with three treatments per replication, and 15 trees per treatment. The plots established were on a Newood-Pence sandy loam soil type and Acer-Tsuga/Maianthemum habitat type (Note: habitat type adjacent to field reflective of site.) Site preparation targeting grass control for all replications consisted of four pounds a.i.per acre of Simazine in a spot application treatment. Further grass control in the second growing season was accomplished with a spot application of Fusilade at a rate of 1/2 pound a.i. per acre. Within each replicated plot, three treatments were compared including 1) protection of the seedling with a plastic tree shelter, 2) protection of the seedling with a rigid plastic mesh, and 3) a control where.seedlings had no protection. Survival and dieback of the seedlings were measured and compared in April of 1990. Dieback was only measured on seedlings that survived. Height growth was measured in September of 1990 after the second growing season. RESULTS TRIAL #1 Initial overall survival, after the first growing season in September 1987 for sheltered trees was 89 percent while for nonsheltered trees survival was 86 percent (Table 1). Initial browse damage occurred on 10 percent of the nonsheltered stock. In September 1990 seedlings established utilizing tree shelters had overall survival decrease to 37 percent (Table 1). Nonsheltered seedlings could generally not be relocated due to mortality, heavy competition and the natural degradation of the flagged metal stakes that marked their location. Those plots with a canopy of young trees or brush overtopping were generally dead or dying. Competition for sunlight in these plots was very high. Individual oak seedlings were noted to maintain their vigor only if sunlight was available. An example of this was in a field plot where six out of ten trees in shelters were alive. Of the nonsheltered trees on this plot only one tree was surviving. All of the nonsheltered trees or remaining stems had severe browse damage. It should be noted that as individual trees grew out of the four foot shelter, browsing above shelters occurred. The Oak Resource in the Upper Midwest 201 TRIAL #2 Survival during the third growing season of June 1989 indicated a total of 87 percent were alive (Table 1). It was noted that understory vegetation was becoming a significant competitor at this time. Survival in September 1990 showed a decrease to 58 percent. Understory competition of stump and stool sprout red maple (Acer rubrum), previously cut in the shelterwood harvest, was overtopping many of the sheltered seedlings. Overtopped seedlings predominantly reflected loss in vigor and mortality. TRIAL #3 In September 1990, after the third growing season, total survival was 46 percent (Table 1). Generally, with these plantings occurring in fresh clearcuts from 1988, vigorous aspen sprouts and other woody vegetation [red maple, blackberries (Rubus spp.), etc.] overtopped the red oak sheltered seedlings.

Height growth was measured in September 1990 after the second growing season. First year survival of seedlings with plastic tree shelters was 98.7 percent. The rigid plastic mesh provided similar results with 94 percent survival, whereas the survival of the control seedlings was only 64 percent. Survival was 34.7 percent greater in the plastic tree shelters as compared to the control. There was no significant difference in survival of the seedlings protected by plastic tree shelters or the rigid plastic mesh. 202 The Oak Resource in the Upper Midwest Height growth after the second growing season of seedlings in plastic tree shelters was 44.3 cm compared to a height of 28.3 cm in the rigid plastic mesh and 24.9 cm in the control seedlings. Height growth was significantly greater in the seedlings in plastic tree shelters then in either of the other two treatments. Dieback of surviving seedlings was on 3.4 percent in the plastic tree shelters, 10.6 percent in the rigid plastic mesh and 60.4 percent in the control (Table 2 and Figures 2A and 2B). Table 2.

Second year height growth of planted red oak seedlings with three treatments for seedling protection. DISCUSSION The trials in this study have demonstrated several benefits in artificial regeneration of red oak seedlings similar to other studies in England and the Lake States (Potter 1988; Lantagne 1990; Teclaw and Isebrands 1991). These include increased initial survival, increased initial height growth, vigor decline with increased overstory competition for sunlight, protection from animal browse, and an increased ability for seedling relocation. Seedlings protected from browse with either the plastic tree shelter or the rigid plastic mesh had similar survival, but the growth of the seedlings was significantly greater in the plastic tree shelters. This is attributed to the enhanced microenvironment created by the plastic tree shelter. Although initial survival and growth of seedlings protected by a plastic tree shelter is encouraging in forested sites, subsequent overtopping competition must be controlled to realize future benefits. Survival over time in all of the forested situations decreased due to competition. This scenario is similar to other natural and artificial regeneration studies, indicating the need to control competition (even when using tree shelters) to have a significant number of red oak seedlings survive and become established. The Oak Resource in the Upper Midwest One of the intriguing findings of the old field trial was the reduction of dieback of seedlings protected with plastic tree shelters as compared to the control. In the spring of 1990 only 3.4 percent of the seedlings in the plastic tree shelters exhibited dieback, whereas 60.4 percent of the control seedlings had some dieback. This is quite the opposite of what was expected, with the plastic tree shelters creating a greenhouse effect and prolonging the growing season of the seedlings, theoretically making them more susceptible to fall frosts. Reasons for this are unknown, but it could be postulated that the seedlings in the plastic tree shelters had better growing conditions throughout the year, were more vigorous, were less susceptible to desiccating winter winds, and less susceptible to a winter dieback of the main stem. CONCLUSION Tree shelters improve height growth and survival in the initial years of red oak seedlings when compared to nonsheltered seedlings. In the forest trials, survival consistently was excellent after the first growing season, but decreased over time due to overtopping competition. Planting oak seedlings with shelters in heavy competition for sunlight is not recommended unless these seedlings can be released. Protection from animal browse is a benefit and dieback appears to be significantly less in sheltered seedlings. The use of plastic tree shelters can assist in the establishment of red oak seedlings.

If there have been problems with compliance and unacceptable work up to this point, corrective measures shall be taken prior to accepting plant stock. HOW A four step process is used in measuring objective criteria to determine whether or not plant stock is physically acceptable upon delivery, initial installation, replacement installation, and upon final acceptance. The criteria are defined in the four sets of guidelines which follow in this section. 1) ACCEPTING DELIVERY OF PLANT STOCK. 2) ACCEPTING PLANT TYPE AND FORM. 3) ACCEPTING PLANT SIZE. 4) ACCEPTING PLANT HEALTH AND VIGOR. • WHY It is necessary to have clearly defined and objective standards and criteria which can be measured as a basis for all landscape project work to ensure that: Landscape Contractors, Material Suppliers and Mn/DOT Personnel know exactly what the Project expectations and requirements are. Inexperienced personnel can carry out their responsibilities and perform in a consistent and satisfactory manner. - . High levels of "quality" in materials and work are promoted and obtained. The landscape design intent is satisfied. 7B-1 ACCEPTING PLANT STOCK DELIVERY WHAT Prior to acceptance, the Contractor must provide: - A 3 day notice prior to the expected date of plant material delivery. - A dated, current year Minnesota Nursery Stock Dealer or Grower Certificate/Certificate of Nursery Inspection. - A final (revised if changes occurred) Certificate of Compliance. - Bill of lading or invoices to validate the Certificate of Compliance. Plant stock with identification labels attached to all individually shipped plants and/or all bundles, bales, flats, or boxes of plants. The specified plant material (no substitutions unless authorized). Good quality plant stock in good condition. Proper storage, transport, and handling must be evident. See Appendix D for the Minnesota Nursery Law/The Plant Pest Act for further explanation of certification and plant care, storage, and handling requirements prescribed by State law. HOW 3 Day Notice The 3-day notice must be written and it is recommended that the Contractor send the notice by facsimile transmission and an accompanying phone call for verification with the Project Engineer or Inspector. Nursery Stock Dealer/Grower Certificate A copy of the Dealer or Grower Certificate must be provided by the landscape Contractor if the certificate was not provided at the Pre-Construction conference or prior to plant delivery.

Ilik ! / - I Plants are labeled by either a �/ common name or botanical name. For example: ft/ < < {t , ' The common name is: L—Y s.stir 4404 °'�` Marshall's seedless ash /-7--- 111 (1/1/, Q The botanical name is: . . . ef orGenus = Fraxinus Species = pennsylvanica '1-iir Variety = 'Marshall's Seedless' Plants must be labeled - Reject plants labeled differently from the plants specified unless a substitution has been authorized. Plant stock substitutions should not be authorized unless the Contractor has provided written documentation to the Engineer that the plants cannot be obtained in full or split orders from Mn/DOT's Partial List of Nursery Stock Growers and Suppliers (Appendix E). If Mn/DOT's Landscape Unit verifies that the specified plant stock is not available, the Landscape Unit will recommend substitutions or waiting until the next acceptable plant installation period to obtain the specified plant stock. Storage, transport, and handling If all the plant stock documentation is acceptable, examine the plant stock for proper storage, transport, and handling in the truck before it is unloaded. Plant stock must arrive in good condition. Plants are perishables and a perfectly acceptable plant can become worthless in a short time through improper care. Determine that bare root material was protected against drying out during transport. To remain viable and healthy, roots must be kept covered with a suitable moisture- holding material (moist mulch, straw, soil, etc.), or refrigerated (34 to 38 degrees F.) and humidified (90 to 95% relative humidity). Feel the roots and scrape some with a fingernail to ensure that the woody tissue is pliable and whitish colored rather than dried out and darker colored. Determine that plant material has been adequately protected against damaging climatic conditions such as sun, wind, or freezing temperatures. Some bare root plants require "sweating" before planting because they do not come out of dormancy easily. For a list of the plants that require "sweating" and for procedural information, see Initial Planting Operation Installation Requirements, section 7H. 7B-8 ' Plants transported in an open vehicle must have a 1vit t y �• protective covering over the plants. Open vehicle--plants must be covered Plants transported in closed vehicles must have adequate ifn ventilation to prevent overheating damage or sweating ` _ which prematurely breaks their dormancy. Deciduous 1111' ; plants must arrive in a dormant condition unless specified Closed vehicles otherwise.

The foliage must be wrapped to prevent the leaves from drying during transport. • If storage, transport and handling of plant stock are Protect leaves during acceptable, inspect plants for compliance and acceptance transport either in the delivery truck or as they are unloaded. - Accept only specified plants that meet the criteria for type, form, size, health and vigor following in this section of the Guidelines. Allow plenty of time to inspect the plants and do not rush since this is the most important part of landscape project inspection. Often an entire semi-truck load of plants is delivered at one time. Begin by looking at individual plants or by opening bundles of bare root plants. Look at a representative sampling. If you see numerous problems, examine all plants very closely--many or all of the plants may be unacceptable. Although the Contractor may be capable of bringing unhealthy, undersized, poorly formed, or otherwise substandard plants into compliance by the end of a 2-year Plant Establishment Period, these plants will not be accepted for initial plant installation. 7B-9 my ,, - /, yrs, / . �,,, According to the Minnesota Nursery Law/The Plant , k2IieVi' '��' Pest Act, nsery stock held, spp , and stored • y. for sale, until subsequently being planted, must be ~; % "�, : watered and protected so the roots are moist at all ?)" • . - - ' •.-�:_}- times.

Plants with dry roots may fail to grow roots are always cool and moist normally or die, depending on the length of time, extent of injury and species (See Appendix D). A "reefer"or refrigerated truck is a good way to keep plants cool, •. moist, and dormant until it is time to plant. tyzy M ry Reject unacceptable plants as they arrive, and before they Closed refrigeration are installed, whenever possible. WHY A 3 day notice is needed to allow the Engineer to schedule enough time and personnel to properly inspect all plant material. Contractors operating without a current Nursery Stock Dealer or Grower's Certificate are in violation of State law and Mn/DOT exposes itself to liability and punitive action by permitting them to perform work. Accepting plants without all acceptable plant stock documentation poses serious and unacceptable risks that may not show up as dead, dying, or diseased plants until after final acceptance of the Contract. Plants originating and grown outside acceptable hardiness zones and acceptable Midwest and northern growing ranges will not reliably survive in Minnesota. An EXCEPTION exists: Plants, seed, or root and graft stock from the acceptable (midwest and northern source) hardiness zones area, if they are Minnesota zone hardy, can be grown or used for propagation outside the acceptable source and hardiness zones area and can then be brought back and planted in our area with reliable survival. Timing of transport may be critical to prevent potential injury from cold weather to unacclimated plants being moved through or between seasonally varied geographic areas. Bills of lading or invoices must be checked to verify the accuracy of the Certificate of Compliance since Contractors continually seek and often switch to different suppliers to obtain better quality plants, cheaper plants, or better payment terms. 7B-10 Potential problems with uncertified plants may not show up as serious problems until after the Contract period ends or they may show up as serious disease and insect problems that endanger plants in the adjacent area. Therefore, uncertified plants cannot be accepted. Without labels, it is difficult to properly identify many plants and their varieties, especially when they are dormant, therefore unlabeled plant stock must not be accepted. Requiring written documentation and verification that specified plant stock is unavailable before authorizing substitutions, provides fairness relative to unsuccessful bidders who may have added extra costs for materials that are more expensive due to limited availability. This procedure also makes every reasonable effort to obtain the specified plants and to avoid compromising the design intent. 7B-11 THE LAKE LUCY ENVIRONMENT PRESERVATION COMMITTEE April 24, 1998 Mr. Homer Tompkins President Contractors Property Developers Company 9110 83rd Avenue North Brooklyn Park, MN 55445 Mr. Richard A. Loscheider President Loscheider Custom Homes 1607 Florida Avenue North Golden Valley, MN 55427 Dear Mr. Tompkins & Mr. Loscheider, Thank you for holding the neighborhood meeting on April 9th regarding the proposed development for the north shore of Lake Lucy. Your presentation was well organized, and all of you appeared to be truly interested in the input of the neighbors affected by this project. Per your request, we would like to comment on the plan that you presented. We ask that you consider our comments and serious concerns, and integrate them into the final plan that you present to the Planning Commission, and ultimately to the City Council. If possible, we would appreciate another presentation prior to any submission of your preliminary plat. We want you to understand that we are not opposed to this property being developed. We acknowledge that, subject to city ordinances, a property owner has the right to develop his/her property. We are, however, steadfast in our commitment that the property be developed with an appreciation and sensitivity to the surrounding neighborhood. This will make your project a success, and will also benefit the adjacent property owners and the city as a whole. The plan that you presented on April 9th appears to be quite similar to the final plan that was withdrawn by Mike Byrne due to the neighbors' and the City Council's concerns about it. The primary difference is that you appear to have the experience and financial wherewithal to carry it through to completion. We were pleased to see that you had reviewed the chronology surrounding the development of this project, and have thought about one of the key issues, i.e., the removal of existing, mature tree canopy. But let us briefly review our list of major concerns and our suggestions to improve this plan: 1. Lot Size A number of your proposed lots are only 15,000 to 20,000 square foot lots, and most of these are backed up along the Randall's 12+ acre lot. This density is inconsistent with not only the Randall's property, but also with all of the surrounding properties. Apart from Pointe Lake Lucy, most, if not all, other homesites along the east, west, north sides, and across from the south shore are 5 or more acres. Even Pointe Lake Lucy (which had a much different original terrain......high, wide, flat and relatively open) has a density of 1.71 units per acre. Given the uniqueness of the parcel you are looking to develop (as further discussed below), a minimum (not average) lot size of no less than 44,000 square feet, or 1 acre, would be more consistent with the surrounding lots in this neighborhood. We envision a development somewhat like "The Frontier", the Streeter and Associates development on the East Side of Chanhassen. This development utilizes the mature trees and natural rolling terrain to enhance its beauty and value. 2. Homesites Along the Lakeshore Our concerns with having four homes along the lake stem from the following long-term impacts: a. Up to 9' of fill is required for these homesites to be buildable, thereby creating potential erosion and excessive runoff of water and fertilizers into an already nutrient-rich bay. This would also create an unsightly transition with the adjoining properties to the east and west. b. There appears to be a natural spring in this area which is quite active particularly in the Spring (no pun intended). c. Unlike the Pointe Lake Lucy development, there would be very little setback of the homes from the wetland area, thereby providing virtually no natural buffer for such runoff. d. This area is an active and sensitive wildlife corridor. The environmental impact of disturbing this area with 4 homesites should be seriously considered. 3. Clearing and Grading of a Significant Portion of the Site • As you indicated at the neighborhood meeting, the unique topography of this site makes it "very difficult to develop". According to your proposed plan, to do so requires the removal of a significant amount of existing vegetation, including many mature trees. Your forester. while quite thorough and knowledgeable, said that many of the trees around the inland marsh were in various stages of disease or instability. However, no real estimates could be given for the ultimate life span of these "threatened" trees. We are not attempting to "hug" every tree, but your plan (given that it is based upon Mr. Byrne's old plan) would remove upwards of 72% of the existing tree canopy! And this doesn't even account for the trees near the grading limits that would have questionable survival possibilities. We don't think this reasonable and consistent with the surrounding neighborhood. Also, due to the difficulty of developing this parcel, shouldn't more thought and consideration be given to minimizing the clearing and grading than would otherwise be given to a typical developable property? One unique characteristic of the property is the distinct "valley", or basin that runs from Lake Lucy Road down towards the lake. This basin naturally attracts the runoff of water from the parcel, and happens to be where the road is being proposed. This, along with all of the other clearing and grading, will likely cause the runoff of water to impact Lake Lucy quite dramatically. While you have provided a Walker Pond for the retention of such runoff, we doubt that it is adequate to handle downpours and snow melts. It will also not handle the runoff from the homes along the lake. The excess water from these properties will either flow directly into the lake or into the inland shallow fresh marsh.... and then into Lake Lucy. Our concerns involve the fluctuations in the water level of Lake Lucy when these events occur, together with the impact of the nutrient runoff into the already nutrient-rich marsh and lake. These are our major concerns. Since you've reviewed the file on this property at City Hall, you can see that these are not new concerns. Additionally, these concerns were not only voiced by the neighbors immediately surrounding this property, but were also echoed by the people who reside along the east shore of Lake Lucy, i.e., the Greenwood Shores residents who are also affected. Once again, we are not opposed to the property being developed. It will be developed! And from what we've seen of your group and your product, we believe that your organizations are qualified to do so. With consideration of our concerns, we will support your efforts to develop it. We also desire a win-win situation and outcome. Thank you again for soliciting our input upfront. With due consideration being given to our concerns, we believe a new development can be created on this property which is consistent with the type of natural, sensitive and sensible environment we sought in choosing this neighborhood for our own families.

There is potential future expansion area which would expand the footprint of the building on the southeast portion, towards Audubon Road. The building is proposed to be constructed using rock face block. The PUD requires that all walls shall be given added architectural interest through building design or appropriate landscaping. Horizontal bands and windows accentuate the building. The building footprint is constrained by the shape of the parcel, so the proposal is essentially a rectangle. The applicant does provide variation in the facade of the building to compensate for the ordinary shape. The proposal contains three loading dock areas. Two loading docks are located along Lake Drive West and the third is situated at the intersection of Lake Drive West and Audubon Road. The preliminary plat for Chanhassen Business Center was approved on January 13, 1992. The subject building is proposed to be constructed on Lot 1, Block 1, Chanhassen Business Center 4th Addition, which was approved April 13, 1998. Staff believes that the proposed development meets the standards established as part of the PUD and is recommending approval of the site plan subject to the conditions contained in this report. BACKGROUND On January 13, 1992, the City Council approved the preliminary plat for the Chanhassen Business Center as shown on the attached site plan. The PUD was amended on February 8, 1993 to allow for a church as a permitted use and the final plat for phase I of the project was approved. On April 24, 1995, the Chanhassen Business Center 2nd Addition, subdividing Outlot C into 7 lbts, was approved by the City. On September 25, 1995, the City Council approved the replat of Outlot A into 4 lots, Chanhassen Business Center 3rd Addition. The City Council approved Chanhassen Business Center 4th Addition on April 13, 1998. The Chanhassen Business Center is an industrial/office park on 93.7 acres. The original plat consisted of 12 lots and 2 outlots. The ultimate development for this proposal was to have a total of 700,000 square feet of building area with a mix of 20%office, 25% industrial and 55% warehouse. Eden Trace May 20, 1998 Page 3 GENERAL SITE PLAN/ARCHITECTURE OVERVIEW The proposed building is situated between Lake Drive West and Audubon Road on a triangle- shaped parcel. Access is gained off of Lake Drive West. Parking is located to the north, west and west of the proposed building. Direct views of the loading docks, which are located to the northwest and northeast of the proposal, will be screened by the landscaping. The location of the docks are constrained or limited by the shape of the parcel and the future expansion of the building towards Audubon Road. The applicant is proposing to add landscaping along the parameter of the site to maximize the screening of the loading docks. The building height is 19 feet. It is located 100 feet from property line abutting Audubon Road and 94 feet from Lake Drive West. The 7,500 sq. ft. building is also located 100 feet from the property line abutting Audubon Road, because of the shape of the lot. The materials used on the structure will be rock face block accented by horizontal bands. The building is essentially a rectangle, however, the applicant creates the illusion of a varied faced through smooth face block accents. The applicant has not shown the trash enclosure location. Staff discussed this issue with the applicant and was informed that it will be located inside the building. The overall design is of a high quality providing variation and detail on the facade of the building. DEVELOPMENT STANDARDS The development standards will remain the same as previously approved with the PUD. a. Intent The purpose of this zone is to create a PUD light industrial/office park. The use of the PUD zone is to allow for more flexible design standards while creating a higher quality and more sensitive proposal. All utilities are required to be placed underground. Each lot proposed for development shall proceed through site plan review based on the development standards outlined below. b. Permitted Uses The permitted uses in this zone should be limited to light industrial, warehousing, and office as defined below. The uses shall be limited to those as defined herein. If there is a question as to whether or not a use meets the definition, the City Council shall make that interpretation. Eden Trace May 20, 1998 Page 4 1. Light Industrial. The manufacturing, compounding,processing, assembling,packaging, or testing of goods or equipment or research activities entirely within an enclosed structure, with no outside storage. There shall be negligible impact upon the surrounding environment by noise, vibration, smoke, dust or pollutants. 2. Warehousing. Means the commercial storage of merchandise and personal property. 3. Office. Professional and business office, non-retail activity. FINDING: The proposed uses of light industrial, warehouse and office are consistent with the parameters established as part of the PUD. c. Setbacks In the PUD standards, there is the requirement for landscape buffering in addition to building and parking setbacks. The landscape buffer on Audubon Road is 100 feet. The PUD zone requires a building to be setback 50 feet from the required landscape buffer and public right-of-ways. There is no minimum requirement for setbacks on interior lot lines. The following setbacks shall apply from the right-of-way: Building Parking Required (interior road system) 25' 15' Required (exterior road system) 100' 100' Required (interior lot lines) 10' 0' Provided Lake Drive West 75' 25' Provided from Audubon Rd. 160' 100' Provided from interior lot lines 10' 10' FINDING: The proposed development meets or exceeds the minimum setbacks established as part of the PUD.

Staff has estimated the required parking at 38 spaces. The applicant has provided Eden Trace May 20, 1998 Page 6 4 spaces. The applicant has shown that future parking will be located on the northeast portion of the building. The proposed parking exceeds the ordinance requirements. Building Square Footage Breakdown for entire development Office 20% 120,700 sq. ft. Manufacturing 25% 150,875 sq. ft. Warehouse 54.09% 326,425 sq. ft. Church 0.91% 5,500 sq. ft. Total 100% 603,500 sq. ft. FINDING: The proposed development meets the development standards established as part of the PUD. The city has previously approved the following square footage within the Chanhassen Business Center: church- 5,500 square feet; office - 54,303 square feet (National Weather Service, Power Systems, Paulstarr Enterprises and Construction Heaters, KNS Investments, Postal Service and Matthews); and warehouse - 74,192 square feet (Power Systems, Paulstarr Enterprises, Postal Service, Construction Heaters and Matthews). e. Building Materials and Design 1. The PUD requires that the development demonstrate a higher quality of architectural standards and site design. All mechanical equipment shall be screened with material compatible to the building. 2. All materials shall be of high quality and durable. Masonry material shall be used. Color shall be introduced through colored block or panels and not painted block. 3. Brick may be used and must be approved to assure uniformity. 4. Block shall have a weathered face or be polished, fluted, or broken face. 5. Concrete may be poured in place, tilt-up or pre-cast, and shall be finished in stone, textured or coated. 6. Metal siding will not be approved except as support material to one of the above materials or curtain wall on office components or, as trim or as HVAC screen. 7. All accessory structures shall be designed to be compatible with the primary structure. Eden Trace May 20, 1998 Page 7 8. All roof mounted equipment shall be screened by walls of compatible appearing material. Wood screen fences are prohibited. All exterior process machinery, tanks, etc., are to be fully screened by compatible materials. 9. The use of large unadorned,prestressed concrete panels and concrete block shall be prohibited. Acceptable materials will incorporate textured surfaces, exposed aggregate and/or other patterning. All walls shall be given added architectural interest through building design or appropriate landscaping. 10. Space for recycling shall be provided in the interior of all principal structures for all developments in the Business Center. FINDING: The applicant is proposing the use of rock face block with smooth face block accents. The PUD requires that all walls shall be given added architectural interest through building design or appropriate landscaping. The building design is of a high quality and meets the intent of the PUD design requirements. f. Site Landscaping and Screening 1. All buffer landscaping, including boulevard landscaping, included in Phase I area to be installed when the grading of the phase is completed. This may well result in landscaping being required ahead of individual site plan approvals but we believe the buffer yard and plantings, in particular, need to be established immediately. In addition, to adhere to the higher quality of development as spelled out in the PUD zone, all loading areas shall be screened. Each lot for development shall submit a separate landscaping plan as a part of the site plan review process. 2. All open spaces and non-parking lot surfaces shall be landscaped, rockscaped, or covered with plantings and/or lawn material. 3. Storage of material outdoors is prohibited unless it has been approved under site plan review. All approved outdoor storage must be screened with masonry fences and/or landscaping. 3. The master landscape plan for the CBC PUD shall be the design guide for all of the specific site landscape developments. Each lot must present a landscape plan for approval with the site plan review process. 4. Undulating or angular berms 3' to 4' in height, south of Lake Drive along Audubon Road shall be sodded or seeded at the conclusion of Phase I grading and utility construction. Eden Trace May 20, 1998 Page 8 The required buffer landscaping may be installed in phases, but it shall be required where it is deemed necessary to screen any proposed development. All required boulevard landscaping shall be sodded. 5. Loading areas shall be screened from public right-of-ways. Wing walls may be required where deemed appropriate. FINDING: Existing conditions on site include boulevard trees planted along Audubon Road and Lake Drive West. No tree removal will take place. Existing trees located in proposed construction areas will be transplanted to permanent locations. Since the commercial development is along Audubon Road bufferyard B plantings are required. g. Signage 1. All freestanding signs be limited to monument signs. The sign shall not exceed eighty (80) square feet in sign display area nor be greater than eight (8) feet in height. The sign treatment is an element of the architecture and thus should reflect with the quality of the development. The signs should be consistent in color, size, and material throughout the development. The applicant should submit a sign package for staff review. 2. Each property shall be allowed one monument sign located near the driveway into the private site. All signs require a separate permit. 3. The signage will have consistency throughout the development. A common theme will be introduced at the development's entrance monument and will be used throughout. 4. Consistency in signage shall relate to color, size, materials, and heights. FINDING: The applicant has not provided details regarding signage for the site. All signs must receive a permit prior to installation. h. Lighting 1. Lighting for the interior of the business center should be consistent throughout the development. 2. A decorative, shoe box fixture (high pressure sodium vapor lamps) with a square ornamental pole shall be used throughout the development area for area lighting. 3 Lighting equipment similar to what is mounted in the public street right-of-ways shall be used in the private areas. Eden Trace May 20, 1998 Page 9 4. All light fixtures shall be shielded. Light level for site lighting shall be no more than 1/2 foot candle at the property line. This does not apply to street lighting. FINDING: The applicant has not provided lighting details or calculations for this development. However, city ordinance and the PUD standards provide sufficient control to assure compliance to an established standard. GRADING & DRAINAGE SITE GRADING The site was previously graded in conjunction with Chanhassen Business Center 15` Addition. Upon review of the preliminary grading plan, it appears building and parking areas will blend into the existing land form. The site will be re-graded to prepare the building pads and parking lot areas. If exporting or importing of earthwork materials is necessary, a haul route and traffic control plan will need to be submitted to the City for review and approval prior to construction commencing. The site contains an existing earth berm along Audubon Road. The berm will not be disturbed as a result of this project. The top of berm will be approximately three feet above the first floor elevation. Staff believes that the berm should be extended northerly to wrap around the corner of the site to help screen the east side of the building and parking lots from Audubon Road. DRAINAGE In conjunction with Chanhassen Business Center, a comprehensive storm water drainage system was constructed to address runoff from this site. No on-site ponding will be required with this development. The plans propose on utilizing existing and/or proposed stormwater services to convey stormwater runoff from the site into the City's storm drainage system. The applicant's engineer has submitted to the City detailed storm drainage calculations and a drainage area map for a 10 and 100-year storm event,24-hour duration for staff review and approval. STREETS The project is proposed to be accessed through a new driveway access off of Lake Drive West. Staff has reviewed the location of the driveways and are comfortable with the location. The parking lot provides adequate traffic circulation around the building site. A future parking area is Eden Trace May 20, 1998 Page 10 proposed in the easterly corner of the site; however, no layout is shown. There is an existing 6- foot wide concrete sidewalk on the north side of Lake Drive West. All driveway access points on Lake Drive West shall incorporate the City's industrial driveway detail apron (Detail Plate No. 5207). This will also decrease the driveway radii onto Lake Drive West. There are existing City street lights along Lake Drive West that are not shown on the plans. The developer should verify that the access points will not be in conflict with the City's street lights. The applicant shall be responsible for any relocation of street lights in conjunction with site improvements. UTILITIES Municipal utility service is available from Lake Drive West. The plans propose on extending sanitary sewer and water service from Lake Drive West. According to city records, there are no sanitary sewer services extended to the property line. The plans propose on cutting open Lake Drive West and extending a sanitary sewer service from the existing sewer manhole. To reduce impact to the street and traffic staff is recommending an inside drop into the manhole. This will minimize the trench width. In addition, the contractor will be able to maintain one lane of traffic along Lake Drive West. Staff is also recommending Lake Drive West be restored in kind within seven days after construction commences on the sewer service. A $2,500 escrow will be required to guarantee restoration of Lake Drive West. No open trenches will be permitted overnight. The site does have water service extended to the property line from Lake Drive West. The proposed sanitary sewer and water improvements shall be installed by the developer and/or their assignee. The utility improvements with the exception of a portion of the storm sewer will be considered private and not maintained by the City. These utilities will be inspected by the City's Building Department. The utility improvements shall be constructed in accordance with the City's latest edition of Standard Specifications and Detail Plates and/or State Plumbing Codes. This property has been previously assessed for sewer and water improvements under City Project No. 91-17. However, according to city ordinance,the property may be subject to additional sewer and water hookup charges at time of building permit issuance. Sewer and water hookup charges are determined based on the number of sewer availability charges (SAC units) which is determined by the Metropolitan Council Environmental Services upon plan review of the building. The applicant and/or contractor applying for the building permit will be responsible for the sanitary sewer and water hookup charges. 1998 hookup charges for sanitary sewer and water are $1,216 and$1,584, respectively, per unit. Eden Trace May 20, 1998 Page 11 MISCELLANEOUS The applicant should be aware that no construction activities may commence on the site until the final plat and development contract for Chanhassen Business Center 4th Addition has been recorded. EROSION CONTROL The preliminary erosion control plan is in general conformance with the City's Best Management Practice Handbook. Catch basins shall also be protected with hay bales and silt fence or rock construction dikes. In addition, erosion control fence will need to be installed along the easterly property line for extension of the existing berm. LANDSCAPING Landscaping requirements for the development include parking lot landscaping and buffer yard plantings. The parking lot area is 21,128 square feet. The minimum required amount of landscaping for the parking lot is 1,690 sq. ft. and 7 overstory trees. The applicant meets the landscaping requirement in both area and number of trees. Since the commercial development is along Audubon Road bufferyard B plantings are required. The planting area is 50 feet in width,but the minimum bufferyard standard of 30 feet width will be applied. For every 100 feet, one overstory, 2 understory and 2 shrubs are required. Frontage along Audubon is approximately 460 feet, therefore buffer yard plantings must include at least 5 overstory trees, 9 understory and 9 shrubs. The applicant has proposed 5 overstory, 15 evergreens, and 3 understory. Staff feels the absence of shrubs in the plantings is compensated for by the evergreen plantings and that the buffer yard is adequate. Staff recommends the three additional trees be planted in the eastern corner of the property to help screen the parking lot from Audubon Road and incoming traffic. These trees should be an extension of the bufferyard plantings and not interfere with any plans for future expansion of the parking lot. LIGHTING/SIGNAGE The applicant has not provided lighting details or calculations for this development. The applicant has not provided signage details for the project. However, city ordinance and the PUD standards provide sufficient control to assure compliance to an established standard. Eden Trace May 20, 1998 Page 12 SURFACE WATER MANAGEMENT PLAN (SWMP) 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. SWMP water quality charge is $4,633/acre for industrial developments. The fees were paid at the time when Chanhassen Business Center 4th Addition was platted. The applicant has provided on-site water quality ponds in accordance to the SWMP in Chanhassen Businesses Center 2nd Addition; therefore,these fees have been waived. 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. Industrial developments have a connection charge of$4,360 per developable acre. The fees when paid at the time when Chanhassen Business Center 4th Addition was platted. INSIDE PARKING At grade overhead doors raise a concern that motor vehicles may be parked in the building. There are specific code requirements if this occurs. The plumbing code requires a flammable liquids separator if vehicles are parked in the building, and the building code requires a one-hour fire- resistive occupancy separation between a parking area and a warehouse, office, manufacturing facility or storage facility. The Inspections Division interprets parking as being overnight parking. The presence of a motor vehicle in the building during the operation of the facility does not trigger the additional code requirements. PERMIT REQUIREMENTS Plans are often bid before the building code plan review is done by the Inspections Division reviewer, making changes necessary for code compliance difficult and expensive to incorporate later. Accordingly,the developers and designers my desire should meet with Inspections as early as possible to discuss commercial building permit requirements and the code review process. Eden Trace May 20, 1998 Page 13 SITE PLAN FINDINGS In evaluating a site plan and building plan, the city shall consider the development's compliance with the following: (1) Consistency with the elements and objectives of the city's development guides, including the comprehensive plan, official road mapping, and other clans that may be adopted; (2) Consistency with this division; (3) Preservation of the site in its natural state to the extent practicable by minimizing tree and soil removal and designing grade changes to be in keeping with the general appearance of the neighboring developed or developing or developing areas; (4) Creation of a harmonious relationship of building and open space wi:h natural site features and with existing and future buildings having a visual relationship to the development; (5) Creation of functional and harmonious design for structures and site features, with special attention to the following: a. An internal sense of order for the buildings and use on the sit and provision of a desirable environment for occupants,visitors and general community; b. The amount and location of open space and landscaping; c. Materials,textures, colors and details of construction as an expression of the design concept and the compatibility of the same with adjacent and neighboring structures and uses; and d. Vehicular and pedestrian circulation, including walkways, in:erior drives and parking in terms of location and number of access points to the public streets,width of interior drives and access points, general interior circulation, separation of pedestrian and vehicular traffic and arrangement and amount of parking. Eden Trace May 20, 1998 Page 14 (6) Protection of adjacent and neighboring properties through reasonable provision for surface water drainage, sound and sight buffers, preservation of views, light and air and those aspects of design not adequately covered by other regulations which may have substantial effects on neighboring land uses. Finding: The proposed development is consistent with the comprehensive plan, the zoning ordinance, the design guidelines established as part of the Chanhassen Business Center PUD with the modifications outlined in the staff report, and the site plan review requirements. The site has few existing natural amenities due to previous development in the area. The site design is compatible and harmonious with the approved industrial developments throughout the City.

Upon review of the preliminary grading plan,it appears building and parking areas will blend into the existing land form. The site will be re-graded to prepare the building pads and parking lot areas. If exporting or importing of earthwork materials is necessary, a haul route and traffic control plan will need to be submitted to the City for review and approval prior to construction commencing. The site contains an existing earth berm along Audubon Road. The berm will not be disturbed as a result of this project. The top of berm will be approximately three feet above the first floor elevation. Staff believes that the berm should be extended northerly to wrap around the corner of the site to help screen the east side of the building and parking lots from Audubon Road. DRAINAGE In conjunction with Chanhassen Business Center,a comprehensive storm water drainage system was constructed to address runoff from this site. No on-site ponding will be required with this development. The plans propose on utilizing existing and/or proposed stormwater services to convey stormwater runoff from the site into the City's storm drainage system. The applicant's engineer has submitted to the City detailed storm drainage calculations and a drainage area map for a 10 and 100-year storm event, 24-hour duration for staff review and approval. The City of Chanhassen.A growing community with clean lakes,quality schools,a charming downtown,thriving businesses,and beautiful parks.A great place to lire,work,and play Sharmin Al-Jaff Quantum Controls Site Plan Review May 12, 1998 Page 2 STREETS The project is proposed to be accessed through a new driveway access off of Lake Drive West. Staff has reviewed the location of the driveways and are comfortable with the location. The parking lot provides adequate traffic circulation around the building site. A future parking area is proposed in the easterly corner of the site; however, no layout is shown. There is an existing 6-foot wide concrete sidewalk on the north side of Lake Drive West. All driveway access points on Lake Drive West shall incorporate the City's industrial driveway detail apron (Detail Plate No. 5207). This will also decrease the driveway radii onto Lake Drive West. There are existing City street lights along Lake Drive West that are not shown on the plans. The developer should verify that the access points will not be in conflict with the City's street lights. The applicant shall be responsible for any relocation of street lights in conjunction with site improvements. UTILITIES Municipal utility service is available from Lake Drive West. The plans propose on extending sanitary sewer and water service from Lake Drive West. According to city records, there are no sanitary sewer services extended to the property line. The plans propose on cutting open Lake Drive West and extending a sanitary sewer service from the existing sewer manhole. To reduce impact to the street and traffic staff is recommending an inside drop into the manhole. This will minimize the trench width. In addition, the contractor will be able to maintain one lane of traffic along Lake Drive West. Staff is also recommending Lake Drive West be restored in kind within seven days after construction commences on the sewer service. A $2,500 escrow will be required to guarantee restoration of Lake Drive West. No open trenches will be permitted overnight. The site does have water service extended to the property line from Lake Drive West. The proposed sanitary sewer and water improvements shall be installed by the developer and/or their assignee. The utility improvements with the exception of a portion of the storm sewer will be considered private and not maintained by the City. These utilities will be inspected by the City's Building Department. The Sharmin Al-Jaff Quantum Controls Site Plan Review May 12, 1998 Page 3 utility improvements shall be constructed in accordance with the City's latest edition of Standard Specifications and Detail Plates and/or State Plumbing Codes. This property has been previously assessed for sewer and water improvements under City Project No. 91-17. However, according to city ordinance, the property may be subject to additional sewer and water hookup charges at time of building permit issuance. Sewer and water hookup charges are determined based on the number of sewer availability charges (SAC units) which is determined by the Metropolitan Council Environmental Services upon plan review of the building. The applicant and/or contractor applying for the building permit will be responsible for the sanitary sewer and water hookup charges. 1998 hookup charges for sanitary sewer and water are $1,216 and $1,584, respectively, per unit. MISCELLANEOUS The applicant should be aware that no construction activities may commence on the site until the final plat and development contract for Chanhassen Business Center 4'h Addition has been recorded. EROSION CONTROL The preliminary erosion control plan is in general conformance with the City's Best Management Practice Handbook. Catch basins shall also be protected with hay bales and silt fence or rock construction dikes. In addition, erosion control fence will need to be installed along the easterly property line for extension of the existing berm. RECOMMENDED CONDITIONS OF APPROVAL 1. All driveway access points onto Lake Drive West shall incorporate the City's industrial driveway apron (Detail Plate No. 5207). The developer shall be responsible for relocating any conflicting street lights along Lake Drive West. 2. Rock construction entrances shall be maintained by the applicant until all parking lots are paved with a bituminous surface. In addition, all catch basin inlets shall be protected with silt fence, rock filter dikes, or hay bales as well. Sharmin Al-Jaff Quantum Controls Site Plan Review May 12, 1998 Page 4 3.

Coffman Development is now requesting approval of the plat with a few minor modifications. These include elimination of the two existing homes,the addition of a cul-de-sac island, different house elevations, and elimination of wetland replacement. The applicant is proposing to develop an 8 lot single family subdivision. This subdivision is a replat of Lots 19-27 in the Minnewashta Park Addition, which was platted and recorded on November 14, 1887. The proposed development also includes a request to vacate and abandon the unimproved right-of-way from this original plat known as "Minnewashta Avenue." Two of the proposed 8 lots will contain the existing homes presently located upon Lots 1 and 3,Block 2 owned by Mrs. Neumann and Ann& Arnold Weimerskirch (daughter and son-in-law of Mrs. Neumann). The proposed access to the development will occur from the proposed 360'cul-de-sac which aligns as an extension of Tanagers Lane to the north. Access to Lot 1, Block 1 along the easterly edge of the property will be the only lot which will gain its access from Piper Ridge Lane. In general, the overall density and large lot single family use of the land is found to be a quality approach to land development in an area that may be classified as "sensitive" from an environmental perspective. The applicant is requesting a conditional use permit for a recreational beachlot. The beachlot does meet the standards to allow 3 docks with 3 boats. Staff is recommending that there be one dock with eight slips to lessen the impacts to the wetland. The applicant is also requesting a wetland alteration permit. Another engineering issue is the location of the storm water ponds. Staff is requesting that they be relocated. BACKGROUND The subject property was a portion of the Minnewashta Park Addition platted in the late 1800's. The portion of the original plat has remained on the books since this time and was never developed according to the plat of record, except with regard to the homes built upon the two lots in the development which presently access Sandpiper Lane via a private drive. Minnewashta Avenue is a platted,undeveloped right-of-way which circumscribes the perimeter of the Lake Minnewashta wetlands area. This roadway was never built from a practical engineering perspective as well as from a strong ecological rationale. To staffs knowledge,there have been no other formal development proposals for this property. SUBDIVISION DESIGN The subdivision is laid out so that there is minimal street improvements planned, large lot features,preservation of wetland areas,etc. The variances identified in this proposal are limited to the following: 1. Street ROW width at 50'vs. the 60' required. Olivewood Subdivision June 3, 1998 Page 3 2. Lot 1, Block 2 existing house front setback 17'vs. 30' required. This home will be removed and the applicant is requesting that a 20' variance be granted. Staff supports this variance because it preserves trees to the rear of the lot.

The proposed subdivision is consistent with the zoning ordinance; Finding: The subdivision meets all the requirements of the RSF, Residential Single Family District and the RD Shoreland Zoning District for Lake Minnewashta. The variances requested are reasonable to protect natural features on the site. 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 applicable land use plan element of the City's Comprehensive Plan. 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 is suitable for development The design works to preserve the natural features of the 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 is served by adequate urban infrastructure, including sewer, water and storm water improvements and streets. 5. The proposed subdivision will not cause environmental damage; Finding: The proposed subdivision is not anticipated to cause environmental or structural damage provided. 6. The proposed subdivision will not conflict with easements of record. Finding: The proposed subdivision will not conflict with existing easements, but rather will expand and provide all necessary easements and vacate and abandon an inappropriate unimproved right-of-way. As a part of this application, a paper street will be vacated. 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 is provided with adequate urban infrastructure Olivewood Subdivision June 3, 1998 Page 5 including proper storm water drainage. SHORELAND REQUIREMENTS The entire development falls within the Shoreland Zoning District of Lake Minnewashta, which is entitled a Recreational Development Lake. All lots meet the minimum 20,000 sq. ft. lot size requirement where adjacent to the lakeshore. The upland area of the lot is the standard imposed by the DNR relative to meeting the minimum lot size area requirements in the Shoreland District. According to the DNR,the upland portion of the lot begins at the OHW (ordinary high water elevation)which is 944.5' (NGVD, 1929) for Lake Minnewashta(please reference the letter from Joe Richter of the DNR dated April 18, 1994). For Lot 2, and all other proposed lots with lake frontage, the OHW level occurs out into the wetland areas. Therefore, all lots are found to be in compliance with the minimum shoreland lot area requirements. These same provisions hold true for the recreational beachlot which will have a total lot area in excess of 70,000 sq. ft., but below the 233,805 sq. ft. gross area which follows the shoreline as identified on the preliminary plat. Based upon these requirements as established by the DNR, staff recommends that the applicant resubmit the lot area calculations based upon a property line which follows the OHW Elevation of 945' (NGVD, 1929). LANDSCAPING/TREE PRESERVATION Tree canopy coverage and preservation calculations for the Olivewood/Neumann property were incorrectly calculated for the original staff report. Correct calculations are as follows: Total upland area (including outlots) 301,756 SF Total canopy area (excluding wetlands) 189,600 SF Baseline canopy coverage 63% Minimum canopy coverage allowed 46% or 138,808 SF Proposed tree preservation 34% or 96,700 SF The applicant does not meet minimum canopy coverage allowed,therefore the difference is multiplied by 1.2 to calculate the required replacement plantings. Difference in canopy coverage 42,108 SF Multiplier 1.2 Total replacement 50,530 SF Total number of trees to be planted 46 trees A replacement planting plan must be submitted to the city for approval. Included in the plan shall be location, species and size of replacements. All replacements must meet minimum size requirements. The applicant has proposed two retaining walls within the development for tree preservation. One is shown on Lot 1, Block 2 and the other on Lot 5,Block 2. If the walls are used to save groupings of trees,they are generally successful. If, however,the walls are used to protect a single tree,the effort is usually in vain. Staff will support the use of a wall on Lot 5,but views the retaining wall on Lot 1 as unnecessary since it appears to be protecting a single tree. The Olivewood Subdivision June 3, 1998 Page 6 applicant may still wish to install both walls, but the city is not concerned with the Lot I wall. Tree conservation easements have been proposed on all lots. No easement documentation has been submitted and staff is reluctant to support preservation easements without reviewing the easement conditions. The applicant will need to submit sample easement restrictions. Tree protection fencing will be required around all trees to be saved on each lot. Prior to grading and excavation for homes on each lot, fencing shall be installed to protect the preservation easement and any other trees to be preserved on the lot. WATER RESOURCES Lake Minnewashta is a Department of Natural Resources (DNR)protected water(10-9P). Therefore, development around the lake will have to meet the DNR's shoreland ordinance requirements. The lake is designated as a recreational lake and this requires a minimum structure set back of 75 feet. Alteration of vegetation and topography shall be regulated to prevent erosion into the lake, fix nutrients, and preserve shoreland aesthetics and wildlife. Limited clearing of trees and shrubs and cutting,pruning,and trimming of trees is allowed to provide a view of the water from the principal dwelling site and to accommodate the placement of stairways and landing,picnic areas, access paths,beach and watercraft access areas, and permitted water oriented accessory structures or facilities. If an area is to be filled for a beach, a DNR permit was secured with the previous application. This permit needs to be renewed. WETLANDS The following is a discussion of the two wetlands associated with the proposed project: A wetland designated by the City as natural surrounds the proposed project on the west and south side and lies adjacent to Lake Minnewashta. The wetland is identified in the City's Surface Water Management Plan(SWMP)as A4-6(2). The wetland is superficially characterized in the SWMP as a wooded swamp (Circular 39; Types 7) or as a seasonally flooded palustrine forested wetland(Cowardin PFO 1 C). The value and function of this wetland as identified in the City's Wetland Ordinance highly discourages alteration to this wetland. A wetland designated by the City as agricultural/urban is located in the northeast corner of the proposed project(Lot 1,Block 1). The wetland is identified in the SWMP as A4-6(1). The wetland is superficially characterized in the SWMP as a combination of inland shallow and deep fresh marsh and wooded swamp(Circular 39; Types 3/4/7) or as a seasonally flooded palustrine emergent/forested wetland(Cowardin PEM/FO 1 C). The value and function of this wetland as identified in the City's Wetland Ordinance may allow some alteration to the wetland under the use of the Wetland Conservation Act's (WCA) sequencing criteria. City Wetland Ordinance-Permit Requirements The City will require a wetland alteration permit for any impacts to associated wetlands. In general the ordinance follows the guidelines of the WCA with the additional requirement of a Olivewood Subdivision June 3, 1998 Page 7 buffer strip and a structure setback from the buffer strip. The structure setback and buffer strip widths are as follows: Wetland Buffer Strip Buffer Strip % Native Structure Setback from Type Minimum Vegetation in Outer Edge of Buffer Average Width Buffer Strip Strip Natural 10 - 30 ft 20 ft Required 40 ft Ag/Urban 0-30 ft 10 ft Optional 40 ft WCA The WCA permanent rules have been effective since January 1, 1994 and the City of Chanhassen is the Local Governing Unit(LGU) administering the WCA permit process. The replacement requirement is not longer necessary because the legislature amended the WCA to allow for 2,000 sq. ft. of alteration without replacement. The LGU may not consider or approve a wetland replacement plan unless the it finds that the applicant has demonstrated that the activity impacting a wetland complies with the principles associated with sequencing(WCA rule 8420.0520). If this is considered a minor project by the LGU,however, where the functions and values lost due to the proposed drain or fill are less than that of the proposed replacement, an elaborate search for practicable alternatives will not be required. Clean Water Act Section 404 The discharge of dredged or fill material into any wetland or water area requires authorization, under Section 404 of the Clean Water Act from the Corps of Engineers. The Corps has issued a nationwide Section 404 permit for up to a half acre of fill in isolated wetlands without notification to the Corps and between a half acre and three acres in such basins with predischarge notification [(see 33 CFR 330.5 (a)(26)(ii)]. For impacts to areas between a half acre and three acres, the Corps requires that the applicant demonstrate that the impact cannot be avoided or minimized before considering compensatory mitigation. The wetland for the proposed project can be considered isolated if the impact to the wetland is less than 10,000 square feet. Staff believes impact to the wetland can be avoided by adjusting the lot lines to the south which may eliminate one lot. GRADING The preliminary plans propose grading for the street,utilities and storm pond. The lots are proposed to be custom graded at time of building permit issuance except for Lots 1 and 3, Block 2. On these lots the existing homes will be razed. Detailed grading(with two-foot contours), drainage, tree removal and erosion control plans will be required at time of building permit application for staff to review and approve. The plans propose a stockpile area on Lot 2,Block 1. Staff assumes this area will be used as a staging area when foundations are dug and the excess material will be deposited for use later. Olivewood Subdivision June 3, 1998 Page 8 The stockpile will be required to be removed at the time the last home site is developed. Security will be required to guarantee removal upon completion of the project. In the interim, erosion control measures will need to be maintained. Staff will place a condition in the development contract that this stockpile is a temporary situation and must be removed or reshaped into small berms. The plans propose to save a 12-inch maple tree on the southeast corner of Lot 1,Block 2 which results in a steep bank adjacent the street. Staff commends the applicant for trying to save the tree;however, experience from past projects suggests that this tree will not survive due to construction activities and therefore should be removed and the boulevard graded per the City's standard street section. A small portion of the wetland on Outlot A is proposed to be filled as a result of street grading. Staff believes the boulevards in this area could be reduced to five feet wide with a 3:1 slope to the wetlands to help minimize filling/impacts to the wetlands. The plans propose a water quality pond to be constructed on Lots 3 and 4, Block 2. The dike around the pond is proposed to be built with excavated material from the pond. Staff is concerned that the material used to build the dike may not be structurally sound to prevent the dike from failing in the future. Staff recommends that structural fill material be used to construct the dike. 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, (or$4,424)for single-family residential developments may be waived if the applicant provides water quality treatment according to the City's SWMP standards. To receive this credit the applicant must provide the City with plans for a stormwater quality pond 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 23.95 acres;however,only 5.53 acres is developable land. Therefore,the proposed development would then be responsible for 5.53 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. DRAINAGE Olivewood Subdivision June 3, 1998 Page 9 The wetland located on Lot 1 currently drains through a culvert underneath the existing driveway on Lot 1,Block 2 along Minnewashta Avenue to Lake Minnewashta via an open ditch. This culvert will be eliminated so that the discharge from the wetland outlet will be rerouted through the proposed storm sewer system in the street. The plans propose on conveying stormwater runoff through a series of catch basins which carry the storm runoff to a stormwater pond for pretreatment prior to discharging into the wetland. Stormwater calculations for ponding and piping shall be submitted to the City for review and approval. Stormwater ponds shall meet Walker standards. The storm sewers shall be designed for a 10-year storm event. EROSION CONTROL Erosion control measures need to be incorporated on the plans around the wetland area and stockpile area as well as the stormwater retention pond. The applicant will need to develop a sediment and erosion control plan in accordance with the City's Best Management Practice Handbook (BMPH). The plan shall be incorporated into the fmal grading plan and submitted to the City for review and formal approval with final plat consideration. UTILITIES The site is located within the City's Urban Service Area. Sanitary sewer and water service is available from Sandpiper Lane. The applicant is proposing on extending the sewer and water lines into the site. The utility installation shall be in accordance with the City's latest edition of the Standard Specifications and Detail Plates. The applicant will be required to enter into a development contract with the City and provide the necessary financial security to guarantee installation of the public improvements and conditions of final platting. Final construction plans must be submitted to the City three weeks prior to final plat consideration for review and formal approval by the City Council. There are two existing homes on the parcel. According to the city's records, one home is connected to city sewer and the other one is not. Both homes will be razed. The existing wells and septic system on the site will have to be abandoned in accordance with state and city codes. STREETS The preliminary plat proposes a 50-foot right-of-way along with a 60 foot radius on the cul-de- sac. The city's ordinance requires that a 60-foot wide right-of-way with a 60-foot radius on the cul-de-sac for residential urban development. The applicant is requesting the reduced right-of- way to minimize the impact to the wetland on Outlot A and save trees on Lot 1, Block 2. Staff feels that due to the close proximity of the wetland on Outlot A and the trees on Lot 1,Block 2 along with the existing right-of-way in the neighborhood, the street right-of-way may remain at 50 feet. An island is proposed within the cul-de-sac to reduce impervious surface. Due to the reduced turnaround space available, a No Parking Zone has been established in these cul-de-sacs. The City Council will need to approve a resolution establishing a No Parking Zone in the cul-de-sac. Olivewood Subdivision June 3, 1998 Page 10 The plans will need to include traffic signage for review and approval by the city. The developer is responsible for the cost of the signs and the city will install at no cost. The street appears to be a continuation of Tanagers Lane south of Sandpiper Lane, therefore, it may be prudent to require the street be named Tanagers Lane to maintain a consistency in street names and addresses. The applicant is also requesting vacation of Minnewashta Avenue which exists as a paper street and is located in Lake Minnewashta. The street will never be built and therefore vacation of Minnewashta Avenue is recommended. RECREATIONAL BEACHLOT CONDITIONAL USE PERMIT The development proposal includes a conditional use permit request for a private recreational beachlot. The beachlot area contains a total of 233,805 gross sq. ft. with a total net upland area of 45,165 sq. ft. excluding wetland area. The lot area calculation will need to be recalculated as previously identified. The private beachlot would include a boardwalk which will extend 190' across the wetlands and into the lake area where a common dock would be located with 8 boat slips. Staff strongly supports the combined approach to providing a common lake access via a single boardwalk through the lake wetlands area. This proposal as presented complies with the requirements prescribed by the city's beachlot requirements and the standards as set forth by the DNR. The location selected for dock access is also the most practical from a positioning point as being the shortest path through this important ecological area.

One-third of the park and trail cash contribution shall be paid contemporaneously with the filing of the subdivision plat. The balance,calculated as follows, shall be paid at the time building permits are issued: rate in effect for residential single family property when a building permit is issued minus the amount previously paid. Current residential single family park and trail fee rates are$900.00 and$300.00 per home, respectively. Section 20-232, General Issuance Standards 1.

Reduced tree conservation easement on Lot 1, Block 2, by 1 ,920 square feet A front set back variance was previously approved for the existing home on Lot 1 , Block 2. A 20-foot front set back is requested for the proposed home and is necessary to provide a 60-foot deep house pad. The alternatives to this variance are a variance in the 40-foot wetland buffer set back in the rear yard or shifting the street farther east. The later would result in additional filling of wetland. The construction of a new house on Lot 1 , Block 1 also requires a reduction in the tree conservation easement in the rear yard. The easement line is shown about 20 feet behind the 60-foot by 60-foot pad. The plan requires 812 square feet of wetland filling. Current WCA rules allow filling of up to 2,000 square feet without wetland replacement. Therefore, the wetland mitigation previously shown in Outlot A has been deleted.

I— CHANHASSEN PLANNING COMMISSION REGULAR MEETING MAY 6, 1998 Chairman Peterson called the meeting to order at 7:05 p.m. MEMBERS PRESENT: Allyson Brooks, Matt Burton, Craig Peterson, LuAnn Sidney, Alison Blackowiak, and Ladd Conrad MEMBERS ABSENT: Kevin Joyce STAFF PRESENT: Kate Aanenson, Planning Director; Sharmin Al-Jaff, Planner II; Dave Hempel, Asst. City Engineer; and Phillip Elkin, Water Resource Coordinator BLOOMBERG COMPANIES REQUESTING SITE PLAN REVIEW TO REMODEL A PORTION OF THE FRONTIER BUILDING, WHICH IS PART OF THE ENTERTAINMENT COMPLEX, LOCATED JUST EAST OF THE CHANHASSEN CINEMA. Public Present: Name Address Nancy Mancino 6620 Galpin Avenue Vernelle Clayton 422 Santa Fe Circle Robert Davis 9973 Valley View Fred M. Oelschlager 7410 Chanhassen Road Clayton T. Johnson 1808 Hillside Lane Sharmin Al-Jaff and Dave Hempel presented the staff report on this item. Peterson: Other comments to staff? You talked about architecturally you said that...the recommendations are relatively vague in the conditions. Can you expand upon it a little bit more as far as what you were looking for when you talked about the roof...is that really it or how do you see the building? You define it that significant and architectural differences between...where are you at in that recommendation? Al-Jaff: Well right now the roof edge proposed it has one large roof with no breaks in it whatsoever. It lacks in architectural interest. We don't want to design the building for the applicant but we're making suggestions and one of them would be for instance utilizing dormers. That would give the roof line some interest. The same is used on Country Suites. You can also find something similar on the Dinner Theater so those would be just suggestions. Also with the brick. Right now you have veneer brick along the bottom of the building only. That could be extended up higher. You can see that along the Frontier building facing West 78`h. That would give additional architectural interest to the building. Some type of siding has to take place along Planning Commission Meeting - May 6, 1998 the alley. Again, that hasn't changed. It's still corrugated metal and staff does not believe that this is, what the applicant is proposing,we don't believe is an acceptable solution. Our conditions of approval basically addresses the roof as well as the addition of some type of siding. Peterson: Other questions of staff? Conrad: Sure. ...and this probably doesn't have anything to do with the application right now but do we have, is there a bigger vision for that back side area of the Dinner Theater? You know we've got a neat parking lot there now and the back side of the Dinner Theater is really pretty ugly and there seems to be, it seems to be an area that has some potential. It could be an entertainment area. There could be more than what we're just talking about right now but do we have a vision for that? It just looks outstanding. It looks like it's a cul-de-sac with all sorts of potential. To block off really the back side of the Dinner Theater, which is a functional area. Which is a working area,but in front of that,towards the parking lot, is anything happening? Aanenson: I can address that in a couple of ways. One, I think they've attempted to screen, such as the outdoor storage for Maytag and the dumpster so that's going to help to clean up some of the back but as you go further down, as you pointed out, one of the things that we are looking at now, which you may not be aware of. We undertook a parking study looking at the mix of uses and the potential for additional development back behind the Dinner Theater which would help screen and we want to still enhance the back of that. The applicants may want to talk to what they're looking at as far as further enhancing that property specifically but they are working to screen and enclose some of those storage areas and again put in additional development on the back of that area. Conrad: And it's an aside. It really has nothing to do with what we're talking about but it just looked like great potential. We have an entertainment area back there and you can put, theoretically we can put something up to screen the Dinner Theater and the working parts of that, yet making it something really quite attractive in that area. Anyway, that's an aside. The vision for the alley. What's our vision? You know the hotel side of it's not a pretty thing either so what are we doing? Are we cleaning up one side, the corrugated side versus the other side or what are we going to end up with? Al-Jaff: The alley will be paved. The sidewalk. Conrad: The gravel will go, okay. Al-Jaff: That will go. It is intended to be pedestrian friendly. Heavily traveled. Conrad: And the wall, on the inside of that whatever, what's happening to that wall? It is a pretty ugly wall there so. On the Country Suites side. Al-Jaff: On Country Suites? 2 Planning Commission Meeting - May 6, 1998 Conrad: Yeah. There's an office and there's a pretty ugly wall there so we're making recommendations to the Dinner Theater side but I'm just curious what we're doing to the other. I'm trying to set a standard you know as I, we take a look and making them upgrade it. This one side is bad and the other side is good, you know what have we accomplished? Al-Jaff: When Timber Lounge went in the, we completed the wall was stucco. Conrad: You took it back about 20 feet or so. Al-Jaff: Yes. Conrad: And the rest of the wall between that and the entertainment center is pretty bleak. So I'm just, my question is, what's happening to that? Is it staying that way? Is that the way it is is my question? Al-Jaff: We're talking about the wooded, the area... Conrad: It looks like concrete block and I'm not sure if I've got a good... Well the cinema has some really nice concrete to the surface of it but between that and the front of. Al-Jaff: That will be restored as part of the cinema. Conrad: It will be? Al-Jaff: It will be restored, yeah. Conrad: Okay. So our vision is a walking alley? Aanenson: Right. That's why we put the lights in there so people can park in the front. Go to the Timber Lounge and we wanted to make it inviting... Conrad: ...okay. And that's still our vision? Aanenson: Yes. Conrad: That's what we want to do? Okay. Aanenson: That was our concern about this side to making sure we still have that continuity and I think that kind of goes back to Alison's question that she had last week and how does this tie into the vision and I'm not sure that was articulated last time. How this works into the vision we had before of keeping that. Conrad: Okay. Next question. Do we care about TIF? Aanenson: No. 3 Planning Commission Meeting- May 6, 1998 Conrad: We don't. Aanenson: I think you should know that it's there but that's ultimately for the Council... Conrad: We don't care if they're got money. Aanenson: That's always been the planning, Council. Information to know but it's really the Council's decision ultimately. We're holding this to the standards that we believe it should meet. The Council will ultimately... Conrad: So we don't care if they get money from, it's not our job. Okay. What governs the metal wall? What is the ordinance...? Al-Jaff: The site plan standards, architectural standards prohibit corrugated,prohibits metal. You can use it as an accent or...top of the roof but that's it. It's... Conrad: Site plan standards. What's that? Aanenson: The zoning ordinance. It is in the zoning ordinance for design. Conrad: Okay. Last question. What governs the signage and the location of signage? You're recommending bringing it down. Aanenson: That's in the sign ordinance. Al-Jaff: And there is a variance... Conrad: We're letting them have it. We're just questioning where it should be? Al-Jaff: Correct. One of the conditions of approval of the variance is to bring it down. Conrad: And if we didn't like to bring it down, how could we rationalize not bringing it? How could we rationalize leaving it where they proposed it? What would give us the feeling that we could not follow the ordinance? Aanenson: If we were to go through the variance procedure and the criteria you'd look at that. Maybe you would say because this building's so architecturally significant that it merited something, a different type of a treatment. Some criteria such as that. I guess that's what we're saying is not there. Conrad: We need a positive. We need something. 4 Planning Commission Meeting - May 6, 1998 Aanenson: Well there's a hardship such that there's absolutely no other way to do it. That they would be denied something that everybody else has a right to visually see a sign. Something like that. Conrad: Could it be that? As we take it under, and you once take it off the roof, which is what they've done on the other side which would be real, that would be the integrity of the building. Aanenson: Although what they did do some different architectural treatments such as dormers that may be more difficult to put those up there. Also, they're significantly higher on the back side than they are on the front side. I understand what you're saying, that it would mirror what's happening on the front but these are a lot higher. Our sign ordinance only allows, the highest sign we allow is 20 feet and that's where these are. So it's really almost like a free standing sign. I'm not sure where your sight line's going to be. 20 feet seems pretty high for that type of traffic but. Conrad: You can't see the sign from the street?... Aanenson: No, I'm not saying. I'm not sure that that's, are they marketing to Highway 5? Are people... Conrad: No, we're giving them. They don't have a street frontage and so...there's no visibility except in the parking lot. Al-Jaff: The parking lot, you will be able to see... Burton: Yeah, I'm looking at the staff report and it talks about lighting and then it talks about the lights on the east side. No, on the west side. Are there any other... Al-Jaff: The applicant is not proposing any light fixtures on any other elevation. As far as parking lot lights, those are already there and they were constructed as part of the cinema. Burton: You don't think that...lighting on the east side, on the front or south?... Peterson: Questions? Blackowiak: I have another quick question. One of the conditions talks about the brick being higher. Can you define that? Do you have a specific height in mind or? Al-Jaff: Well it would be extended up to the roof line, similar to what you see along the north elevation facing West 78th Street on the Frontier Building. Peterson: Other questions? Burton: Yeah, one more. On the same condition...that would minimize the appearance of the corrugated metal and I believe I'm correct in that...whole side covered. 5 Planning Commission Meeting- May 6, 1998 Al-Jaff: Correct. Peterson: Any other questions? Seeing none, would the applicant or their designee wish to address the Planning Commission tonight? Clayton Johnson: Hi, I'm Clayton Johnson again from the Bloomberg Companies and I thought before Bob Davis runs throughout plan, I did want to give you,have an opportunity to answer your questions that were asked last time. I felt the public hearing was closed and there were a number of questions that were asked that we didn't get a chance to address and one of them seems to be we can't seem to bury this old entertainment center and I tried to make the point and is that the entertainment complex, as it was presented, is dead. It never got built. And our plan is a totally new plan that, a plan for the Frontier Building. It's the first time it's been presented. I think we've been characterized as all of a sudden changing the plan. We never changed the plan. We are a new applicant with a new use for all the Frontier Building. And there are several things about the old plan that you all raised concerns about that you know you don't like the new plan as well, or functional that relates to the use that we have found. And you know if you have any questions about that, the issue of TIF and some of those things, you know I'd like to be able to answer those. Some of those were asked last time. You must have concerns. Conrad: TIF is not our job. And to be honest with you, I don't know what the entertainment part was. Clayton Johnson: Yeah,as far as the vision, we've got a vision for the balance of the property to the rear. It's been, we've presented it on more than one occasions to the HRA. It involves, Herb's always envisioned an office use on a part of that property and I don't know if you're familiar with the current MLT proposal but basically that's an out growth of Herb's vision. A complimentary use to the Dinner Theater with the parking that is already there for the Dinner Theater would be able to be used during the day. We also envision further retail uses on the east side. However we didn't,you know we're not able to address those. There are current leases on those properties. Those tenants have rights and by agreement we presented this as a phased project and we're dealing with the Frontier Center right now. The east elevation is being addressed. You know the parking lot made that east elevation very visible. There's no question about that. And over there we were faced with four different types of material that we were trying to cover. So the decision was made to panel or to side that whole thing because it really was the only solution that would have been attractive. On the alley side on the other hand though,we simply disagree. You know the code issue is on new structures. This is an existing structure and very honestly we just have a very honest disagreement about what would look better. Herb thinks that a combination of the structural field panel with the billboards that we're going to erect there,and the way it's painted out, is going to look better than siding it. And it's about a $7,000.00 issue. We will side the building but we think it's a mistake. We think that siding on that big structure and that little alley is going to be less attractive. But that's not, that's just a judgment call. Otherwise I'd like Bob Davis to run through, I think the last time, parts of the presentation got missed and so Bob's going to run it through real quick for you. 6 Planning Commission Meeting - May 6, 1998 • Bob Davis: Good evening, I'm Bob Davis. I'm back. Our program here is to rework a building that is 33 years old. Was a lumber yard. It was a steel,metal structural building. I don't want to argue the point. The metal has been there 33 years. We think we can live with it in the alley. We hope you can live with it in the alley. It's not a driving street. We are adding a sidewalk down the alley. People can cross over. But let me go on with some of the items that we're covering here. The design is based on a retail space, what the owner would like to do, and the character of the Frontier complex. And let me go a different direction and remind you what the other buildings look like. Can you focus on the... One of the things that you'll see is a mansard, on almost all of these facades and the last work that Bloomberg did was the High Timber Lounge and that has the high mansard. It has the signs in front of it. Let me pass this around so you can get a good close-up look of it. On this building we're using the same architectural feature of the mansard roof. We're using the same sign pattern. We're raising, or rather lowering the glass on the existing old lumber yard building is 16 feet high. We're lowering it to 10 feet. We're bringing the mansard up here to lower the appearance of the building. This is a structural metal building that in all purposes here on the south side is being covered up. We think it's retail friendly. There are some tenants that would like to lease space here. If we go to the top elevation, the east elevation,as Clayton mentioned there were three different kinds of material on that side. There's some block. There's some wood. There's some metal. The solution is to side that whole panel. It's far more visible to the parking lot. Actually both parking lot areas, but the alley we feel that the metal siding which has been there, can remain. It's a narrow alley. It's not our vision that people would drive down that alley. But if people choose to walk, there is some interest created by these billboards which would have a theme of the history of the community. Let's look at the colors. ...we're looking at a silver, gray on that area where the side is. We're looking at a teal color, which is this color accent for the doors and trim. The brick is a red brick, similar color... building in front. If we take a look at that,the brick does not go higher than the, the brick has columns but it isn't a high wall of brick anymore. The whole brick idea is the same panel that is used all the way around the complex as a wood siding that comes up...and it's 30 inches high and...all around that whole block area. I think it's inappropriate to carry the brick all the way up. I would not choose to do it. I guess I don't want to argue the point... It's a building that really needs a new life. I think all the landscape questions you had last time have been resolved. If you take a look at this. We're quite intensively landscaping three of the corners... This is the alley here from the main street side down to where the cinema entrance is across the way here. This is where the sidewalk is added. The front of this building would be the south side and the entrance of the retail space has sidewalks. The suggestion about flower boxes I think is a good idea. Something that certainly this time of year, if somebody will maintain, could be a nice spark of color. This area will be highly landscaped...and I think we all agree that we're screening the air conditioning units. We're screening the dumpster areas and we're screening some of the loading docks. I'd just like to ask if there any other questions that I can help clarify? Does anybody have anything that needs further explanation? Conrad: Talk to me about signage a little bit. Do you want to talk about that now or should we do it later? Bob Davis: Yes. I think we're matching the High Timber Lounge signage. That has a high mansard roof. The signage is up high. I think this is the place to put the signage. It's on a 7 Planning Commission Meeting- May 6, 1998 parking lot, it's not on the street. If you take the cue from all this other frontier complex, the signs are the same. We're matching what we're doing in the high, what we did on the High Timber Lounge. I think it's inappropriate to pull them down under the mansard. Clayton Johnson: ...we're designing a retail building with a lot of flexibility. The whole... In other words, we don't know exactly how many square feet... One of the reasons for putting the signs on the roof is because we don't know how many tenants we're going to have and how many signs. Once you go to the suggestion,and to bring the signs down below the mansard, you end up with three spaces because there are posts that allow for three spaces. If we were to do that, then we'd have to have the flexibility of going over and putting the signs on the wall, because we don't know how many tenants... So that's one of the reasons. Vernelle did you have... Vernelle Clayton: ...You talked about the signage being, I think it's a real part of architectural element. I guess I'd disagree with the staff report. I think if the signs were on the mansard roof it could be considered to do that. I also, from a perspective,and this frequently unless they're talking about the development and this particular case of while historically I would assume the same thing for the same building. This time I am involved in working with someone who is wanting to be a tenant there and signage is very important to them. They are not at all happy with having signs under the, what we're calling the mansard roof and I don't believe it's a roof but under the mansard. It's not very visible. It's not going to be very easy to have attractive looking signs. There's going to be no background for the signs because behind the sign will be the clutter of the windows and so forth. And visibility is important. If you go out, if you go and sit in the back of that parking lot, coming off Pauly Drive,they will want to be able to be seen from people driving up, not only once you get to the parking lot. So I think that the building will look better with the signs on the roof. I think the mansard will look better with the signs on it and I think it will look better for the building because all the rest of the signs are on what we are calling roofs. Now as I said, I don't think that the roof, I think it's just an attachment to the wall which historically all mansards are anyway. They're not roofs. They're walls. They were made originally to avoid having to pay taxes on wall space in Europe so they really are walls but I guess I just want to be clear that it will be a disadvantage and a hardship for the tenant if they don't have signage that is easily seen because that's a remote spot. I also wanted to mention something about the alley while I have a chance. Historically I've been involved in two projects that related to the alley. Always it was seen...pedestrian oriented walkway. On the last go around, when we talked...kind of lumped together as a"entertainment complex". Which started out as kind of an acronym and kind of got to be...but there's nothing that says that legally it is. We just kind of called it that. At that time the alley was perceived to be something that we would hope to be a little bit fanciful. Kind of fun. At the time we were at the dialogue during the presentation as it were, that based on the comments...even graffiti,planned graffiti... So to summarize then,I think this is,his ideas of the representations of some of our history, with the train,the farmer, and the Indians I guess, or whatever they are. Frontiersmen,okay. Yes. Are kind of a good,a nice kind of fun, intervening kind of thing and I'd like to see those there. I think they're kind of cute. The other side of the wall,just to be perfectly,to clarify, the other side of the wall, everything that is opposite that is the cinema. The hotel starts farther to the north. That's all cinema. They're going to paint it. I think they're past the rough spots and it 8 Planning Commission Meeting- May 6, 1998 will be painted. So it's not going to be anything really gussied up. It's just going to be painted. So we need a balance. And whether you like the corrugated or not, I think the corrugated with the signs, with those, are a lot more fun, I'm sorry, than a flat surface of wood boards. Peterson: Other questions of the applicant from fellow commissioners? ...can answer it obviously. One of the staffs conditions that I alluded to earlier was their condition about adding architectural interest to the mansard roof. Can somebody respond to that? I mean are you thinking of entertaining that idea? No pun intended there. Bob Davis: No. It would be truly a fake dormer for nothing, would serve no purpose. I mean if I can see it was a ventilation for something or it was a window to someplace or, the one on the Dinner Theater actually has a function. I don't want to get caught up on just adding something because somebody thinks it looks better than somebody thinks it looks. I think we need to take the direction from the owner of the building, from the retail tenants who are here and from the frontier complex itself, which really started the idea of the wood shingle roof and shingle mansard. And it's 35 or 40 years old. Peterson: Not putting words into your mouth, you're saying that architecturally right now, the way you presented it is where you want it to be. Bob Davis: Yes it is. Peterson: A number of the conditions that the staff has presented, you're still not in support of is what I'm hearing, right? Bob Davis: I think my charge was here, not to be argumentative. Peterson: ...clarification is where we're at. Bob Davis: But no, I stand on that...what is the dormer for? Aanenson: To add interest to the building. We have fake dormers throughout the entire community. We have them on the hotel next door. I mean your picture doesn't go to the building next door which has pitched roofs. We put them on the new hotel going in. We have fake windows over there too. It's to add architectural interest instead of the mansard roof. I mean people do that all the time. Bob Davis: I think I'll let the owner of the building, if you want to negotiate that, I'll let it go there. Clayton Johnson: I ran it by Herb tonight. You know I guess what do you do? Do you tell Picasso to make the ears bigger on the drawing? I don't know. I'm in the middle but basically we presented that and Herb's vision is that's his architectural vision. And he doesn't, you know the dormers on the Dinner Theater are functional. They're offices. There are windows. I don't know what they did on the hotel. We didn't build the hotel but yes. I ran it by him. You know 9 Planning Commission Meeting-May 6, 1998 there are things that we're willing to compromise and things we're not. We unfortunately, you do have to understand the economics a little bit because there is this conception, or there is this perception the city's going to pay for it. The first thing that happens is, we spend a half a million dollars, $550,000.00 remodeling the building. The second thing that happens is are taxes go from $25,000.00 to $75,000.00 a year. We have to make an economic judgment that what we do to that building is going to functional and going to be of interest and going to be rentable. So when it comes to that, and I'm faced with making the economic decision, who do I rely on? I will rely on Herb. That was the whole purpose of bringing the people here the other night. They weren't here to offer testimonials of Herb. They were here as neighbors saying we like his architecture. We're happy with his design and as an officer of the company I have to bet on that. We are going to be dependent on the financial success and we have had a long history of building buildings that people like and will occupy. So I don't know what more to say. It's an honest disagreement. We're not disagreeing to be disagreeable. It's an honest disagreement. Peterson: Other questions of the applicant? Seeing none, this is not open for a public hearing so I'm just looking for comments from my fellow commissioners. Fred Oelschlager: Can I just say one thing about, Hempel right? Hempel: Yeah. Fred Oelschlager: I'm Fred Oelschlager with Bloomberg Companies. I've been with him for 40 years and to address the questions you had about the sheeting of the water coming down the side of the building. Sharmin and I talked about that I think the first part of the week and shortly after our conversation Steve Kirchman called me because I did talk to him and bring it up to him and so forth. And we had about a 15 minute conversation on the phone about the sheeting of the water on the alley side of that building. And the reason there's gutters and will be gutters on the east side is because we have an erosion problem if we don't have gutters on the east side. That's the Dinner Theater side. Steve basically does not have any problem, in our conversation with the sheeting of the water coming off of that balen roof, which is an oval roof. It comes off uniform. It doesn't shoot out more than about a foot to 18 inches when it does come down. He wanted to know the volume of water that would come off of there. We're researching that right now. He is not insistent upon a gutter. He says it's not necessary. If we have a problem and gutters would have to be used somewhere in the future, we could address it at that time. As of now, the water would come off in a sheet. Hit this flume and still come out every 30 foot intervals underneath the sidewalk into the alley, like the cinema is doing right now. Clayton Johnson: And into the storm sewer... Fred Oelschlager: Right, right, because there are storm sewers... So if that answers your question about whatever. Okay. Peterson: Do you want to respond? 10 Planning Commission Meeting - May 6, 1998 Hempel: Mr. Chairman. I guess I'll disagree a little bit with that. During the summertime and so forth I'll agree but during the late winter, early spring where we do get a lot of freeze/thaw, that dripping will have icicles. You'll have icicles dropping off the roof as well onto a sidewalk area so I guess I would strongly recommend the use of downspout roof gutters is the recommendation. And also there is a storm sewer down the alleyway. They're not proposing to tie into it. It's simply a gutter drain underneath the sidewalk and flow out into the alleyway which is acceptable. The cinema's doing it that way but I would think from an icicle standpoint, that you'd want to look at doing something with that. Fred Oelschlager: Can I just rebuttal on one thing. I meant to mention that at the top here also. ...because water can't away...sheeting operation like that...never have any problems on that building. We did have icing on the cinema building...but putting a gutter on the alley side would cause more... I mean I've been here 40 years, I know what that roof does... Peterson: ...another disagreement. Fred Oelschlager: Well Steve,when I talked to Steve he said if we do have problems...and maybe we can make adjustments at that time. Peterson: LuAnn, do you want to start this one out? Sidney: Sure. I'd be happy to. I had a lot of thoughts about this application and I guess maybe I'll start off with kind of the overall issue that I'm kind of wrestling with and I think the applicant has talked a lot about blending architecture. You know continuation of the architecture from the rest of the complex and I guess I'm having a hard time with that because on the south side of the building now we started a different type of architecture with the cinema and I would think that that would be the focal point where your architecture would tie in to any other buildings that would be developed in that area. So I think the idea that, you know the architecture should reflect the Dinner Theater architecture, I'm not sure if I'm really convinced that it should. And I see this building as a transition between the cinema and the Dinner Theater style of architecture. And at this point I see it more closely tied to what you've already done and it, to me it isn't really showing some you know new type of innovative design that would kind of enhance that south side of that whole complex. So I guess what I'm trying to say is that I'm a little concerned about still the overall architecture and your insistence on a mansard roof but you know I can see where, you know I can live with it but I'm still rather confused by it not tying in with the cinema. Fred Oelschlager: Can I put... Peterson: Let's go through all the comments. I don't think we're going to get response to every one of them so. Sidney: So I guess that's my overall concern and I think when this was presented to the HRA and City Council, you know you were to the point where you were talking about colors of bricks and basic architecture was discussed at that time and I see what was presented at that point, tying more into what the cinema has developed into at this point. So I'd like to jump to a few other 11 Planning Commission Meeting - May 6, 1998 points, specific ones about the corrugated metal. I'm concerned that, I don't think we want that on the side of the building to be visible. We can see it in your photo and we're remarking about that and I don't think it really adds to the appearance of the building. And so I would really want to see us strive for a higher quality material on that side of the building. A few other things. I guess my concern, I guess there's a lot of concern about the signage and I think I'm in agreement with the applicant at this point because I do think the building needs to be really supported by a visible sign. It's in a remote location. I think the applicant does need a break in terms of signage. I'll see if there are some other things that I could comment on here. Maybe I'll leave it at that and have the other commissioners comment. Peterson: Thank you. Matt. Burton: I sort of feel like I'm being pressured to like something that I really don't like...like very much. As we discussed at the last meeting, this is anticipated to be one of the most frequented areas of the city. I think the staff has...held it to higher standards, sort of like the theater and what I think the entertainment complex was envisioned to be. And I don't see this design meeting those higher standards and in terms of just general appearance and design and materials, as LuAnn mentioned, I do not like the corrugated metal on the side. I think that putting, finishing the side really almost anyway it would be an improvement to what's proposed. I find the front to be unappealing. I don't think taking the 78`h Street Frontier complex look around to the back translates very well aesthetically. I think, I tried to figure out why and I think it's just because it's so much bigger in the back and so much higher that it just, I don't believe it works and I know that's a fundamental disagreement that you have with a lot of the comments that have been made. I think that the mansard look,and I don't know if I'm using the right terminology but the big, the mansard hanging off the, over the roof on the south,to me it looks dated also and I look at what was given to us and what was the prior application and I find that significantly more appealing and I also,when I look at that I see without the mansard there and having...wall, you could lower the sign so I think that, those two could go hand in hand. So I guess that's basically it. I just don't really like much about it at all. I agree that the staff's recommendation of the brick veneer should be elevated if this is the plan that we have. And I agree with the staff conditions, but based upon what I'm seeing here, I don't believe that I could support this plan because I just don't think it fits at all into what's envisioned for that area of the city. Peterson: Thank you. Alison. Blackowiak: I still don't know how I'm ultimately going to vote tonight. I have been struggling with this as well. And again architecturally maybe I just don't like it but I guess that's not my main problem. My problem is how does it fit in with the area. Mr. Johnson said that the original plan was dead. That this is not the original plan but although we're not supposed to consider TIF, they were given money based on an original plan and I, I don't know. As a taxpayer I just have a problem giving money to something that I really don't like. And I don't know. I don't want to get into that right now. The mansard roof I don't really think fits with the cinema. We've got an area right now. I think we need to think about how it ties in with the whole southern exposure. This would probably, and if it had a northern exposure. If it looked out onto the parking lot to the north. If it looked out onto the parking lot to the east maybe. But on the 12 Planning Commission Meeting-May 6, 1998 south I don't think it really fits. Matt made a good point about the size of the building and I think that's part of the problem. When you look at how tall the building is, adding a roof,or the mansard in front, is just going to make it look taller and I don't know if that's really what we want to have. It's,aesthetically I'm having a problem with the look of the building. I do agree with the staffs recommendations. I agree that if we do go with this plan,we need to have the brick go all the way to the top. I do not like the corrugated metal on the west side. I do believe we should have some sort of a water catch system, whether it's downspouts or whatever because I'm not convinced that we're not,pedestrians going down that area aren't going to get drenched at any given point from water sheeting off the building. I don't know. I don't think it fits well with the existing cinema and unfortunately the cinema got there first and maybe is tending to set the standard for that area. I don't know if that's good or bad but I think I would like to see this tie in more with the cinema than with the Dinner Theater. Peterson: Allyson. Brooks: Well, I think something really needs to be done with the building as it is now. I mean it really is an eyesore. I'm not overwhelmed with this design. I'm not under whelmed with this design. I think I'm like Alison. I have really mixed feelings. I would love to see something happen in that area. This gives me kind of a bland feeling. I don't think, if we go with this design,to me the signage is okay on the roof. I don't really have a problem with it. I do agree with Vernelle that people do need to see the signs somehow. And for the rest of the recommendations that the planning staff has, I do think we should go with the planning staff. I think they have,they really do have good vision for our community and that we should continue to follow their direction. Peterson: Ladd. Conrad: Isn't it a nice testimonial? Boy,this is sort of...we get into architecture and stuff like that. Thank you for coming back and making the presentation better. I feel better about it. I felt you made some changes and that helps. These are tough issues you know we get into. Architect versus some standards and it gets messy. I can't really figure out some of this stuff. I just can't . so I mean I have to roll with the staff report. I'm not convinced that the alley is going to be, you know I wouldn't make the alleyway a big deal because the flip side of an alley is not a big deal. We're not going to have a beautiful alleyway,walkway there but staff report I think covers it. I really do. I'm comfortable with that. The only thing that I disagree with on the staff report is the signage. Just,we all have personal opinions on this whole thing so that's why we can't even talk about it. You know we've got to rely on the staff to help and stuff but the nice thing about architecture is difference. It's not the sameness. At one point in time we were going to have the whole city being a frontier style city. Isn't it nice that it's not. You know just, so to think that we should match the entertainment center,no. That's boring. That really is boring. I think the variety back there, I think this is fine. Is this my choice? Probably not but that's not my business. I think it will add some variety back there and that's okay. I'm more interested in how else we can, what else we can do back there. I think that's a bigger issue but at hand, you know staff report's fine. Other than the signage, I'm not comfortable with the applicant's signage, yet I don't want to bring it down below the roof. I think that will hide them. I think that's a problem. 13 Planning Commission Meeting - May 6, 1998 I think that destroys some of the visibility and signage is so major in these buildings. It is just a big deal so I'm sort of begging the question here and,not begging the question. I think the staff report is pretty close to being what we should follow. Peterson: Well,you've obviously heard opinions. Across the board from staff. From fellow commissioners and I guess I too have opinions. I'm struggling as to how to articulate them and I think that in many ways we're tasked by the City Council to offer our opinions and recommendation about a lot of different things within the zoning and architectural consistency and compatibility and I think that's really what you're hearing tonight. And we're dealing with Herb's opinion tonight. You guys may not even agree with him. What we're trying to do is listen to your comments. Listen to staff's comments and sort through what's best for the city in that area. And as I gather that, I'll get to you in a second. I'll get to you in a second. Let me finish my comments. As I get to that, and my opinion is not dissimilar to some of my fore colleagues in that architectural compatibility, I just don't see it fitting in to what I envision for that area. Whether you call it the entertainment complex is dead. I don't know if anything is dead. Something will go there and we're going to be asked for our opinion on that also. And I clearly do think that Ladd's comment about Chanhassen was once going to be a frontier city, now aren't we glad it's not. Some people may be glad. Some people may not be. And I think that there's a balance and I think right now where I'm at is that the balance is, this is not the way that I see that area going. I would not support the development...as presented without adhering to the staff's comments in totality. That means that I have a difficult time approving this because the staff is asking for some architectural change that I don't see. I can't approve something that is being asked for in a pretty generic sense. Those are my comments. I saw a hand in the audience. I'd be happy to entertain. Joseph Boyer: I really didn't come here,to this meeting for this but anyway I just wanted to offer my comments. I've been in the building business in this area for 55 years and my family continues on and we have dealt with the Bloomberg Companies and Herb Bloomberg and all their designs and their architecture of their buildings has been excellent. If Herb Bloomberg told me he could make a corrugated building look like a crown jewel, I'd have to believe him. Because this man is that kind of a person and I think what they're giving you is another Bloomberg good design. Very functional,well designed building because that's been their nature. That's their character. That's the way they've always worked. That's my experience with Mr. Bloomberg. Thank you. Peterson: Thank you for those comments. Hearing all the comments from the fellow commissioners,may I have a motion and a second please. Conrad: I'd make the motion that the Planning Commission approve the site plan for the Frontier Building, 98-7 SPR with a variance to allow signs on a building that does not have direct frontage on a public street as shown on the site plan dated March 23rd, 1989. And revised on April 27th, 1998, with the conditions as listed in the staff report dated May 6th with the following changes. That we strike the first line in condition number 6 and that we add a condition number 15 that the applicant work with the City Engineer on the appropriate roof drainage on the west side of the building. 14 Planning Commission Meeting- May 6, 1998 Peterson: Is there a second to that motion? Brooks: I'll second it. Peterson: Any discussion? I don't know how I want to either ask for a friendly amendment or not. On condition number 12, that's a huge condition and I have a hard time voting, passing this onto Council and basically saying let them deal with it. Conrad: Absolutely Craig. Peterson: I think, that's my only concern. On that note I will ask for a. Conrad: Can I respond? The Council will have opinions. Why keep it here? We don't know what...we can't guide these folks and the City Council and the Bloombergs but... Peterson: We've done our civic duty. With that may I ask for a vote. Conrad moved, Brooks seconded that the Planning Commission recommends approval of the site plan for the Frontier Building (98-7 SPR) with a variance to allow signs on a building that does not have direct frontage on a public street, as shown on the site plan dated march 23, 1989, and revised on April 27, 1998, with the following conditions: 1. All existing and proposed roof top equipment shall be screened from views, specifically from Highway 5. 2. The applicant must obtain a sign permit prior to erecting any signage on the site. 3. The letters and logos shall be restricted to 30 inches in height. All individual letters and logos comprising each sign shall have a minimum depth of five inches and shall be constructed with a translucent facing over neon tube illumination. Tenant neon illuminated signage shall consist of store identification only. Copy is restricted to the tenant's proper name and major product or service offered. Corporate logos, emblems, and similar identifying devices are permitted provided they are confined within the signage band and do not occupy more than 15% of the sign area. The applicant shall consider utilizing a font/sign style that is compatible with the building. 4. The applicant and/or their assignee shall be responsible for any additional sewer and water hook up charges associated with remodeling the building based on the number of SAC units determined by the Metropolitan Environmental Sewer Commission. 5. Fire Department recommends the following policies be followed (copies attached). Policy#01-1990 Policy #02-1990 15 Planning Commission Meeting- May 6, 1998 Policy#04-1991 Policy#06-1991 Policy#07-1991 Policy#29-1992 Policy#34-1993 Policy#36-1994 Policy#40-1995 Policy#44-1997 6. The west elevation shall be redesigned in a fashion that would minimize the appearance of the corrugated metal. The brick on the building shall be extended higher. 7. The applicant shall enter into a site plan agreement with the City and provide the necessary financial security in the form of a letter of credit or cash escrow to guarantee compliance with the conditions of approval. 8. The applicant shall add some architectural interest to the mansard roof along the south elevation. This could be done in the form of dormers. 9. The applicant shall add flower boxes around the base of the columns along the south elevation. 10. The design should be revised to collect the roof runoff into downspouts and conveyed underneath the sidewalk. 11. The applicant shall work with the City Engineer for the appropriate roof drainage on the west side of the building. All voted in favor,except Burton and Peterson who opposed, and the motion carried with a vote of 4 to 2. Burton: Basically I articulated earlier. Even with the staff's recommendations, I still don't think it fits in to the area back there. I just have too many problems with this design in that location. Peterson: ...the simple fact is, I want to be sure we get Council's attention that it needs some more work. Motion carried. PUBLIC HEARING: THE CITY OF CHANHASSEN (LGU) DURING THE YEAR 1998 HEREBY PROVIDES NOTICE THAT IT HAS APPLIED FOR A WETLAND ALTERATION PERMIT AS PART OF THE 1998 TRAIL PROJECTS. THIS APPLICATION PROPOSED TO IMPACT 1.4 ACRES OF WETLANDS ALONG PORTIONS OF HWY 7, GALPIN BOULEVARD, POWERS BLVD, GREAT PLAINS BLVD,AND PIONEER TRAIL. THE PROPOSED IMPACT FROM THE TRAIL PROJECTS WILL BE MITIGATED BY 16 Planning Commission Meeting- May 6, 1998 THE CREATION OF NEW WETLANDS AND WETLAND CREDITS FROM THE CITY'S WETLAND BANK. Public Present: Name Address Eileen&Joseph Boyer 3630 Virginia Avenue Jim Sommers 8683 Chanhassen Hills Drive No. Chris Hol 8687 Chanhassen Hills Drive No. Phillip Elkin presented the staff report on this issue. Peterson: Questions of staff? Conrad: Impact on a high grade wetland? Elkin: No. They're all, they all have been either impacted by agriculture or most have been impacted by road construction. Conrad: The BluffCreek wetland Phillip is, what is that? That's the biggest one. Elkin: Right. Conrad: What kind of wetland is that? Elkin: That's still ag urban. If you look down there,they still farm as much as they can. It's just been classified a wetland because over the years the draintiles have broken and it no longer drains effectively to farm so it's a very low grade wetland. Dominated by reed canary grass. I haven't been up here for a while. I wanted to talk. Peterson: Let him go. Other questions? This item is open for a public hearing. May I have a motion and a second please.

REQUEST FOR A CONDITIONAL USE PERMIT AND SITE PLAN REVIEW TO ALLOW A GOLF IMPROVEMENT CENTER/DRIVING RANGE TO BE LOCATED SOUTH OF THE INTERSECTION OF GREAT PLAINS BLVD. AND TH 212 ON PROPERTY ZONED A2,AGRICULTURAL ESTATE DISTRICT, RSS GOLF IMPROVEMENT CENTER. Peterson: Item number 3, RSS Perma Green has been deleted from tonight's public hearings. Aanenson: If I can just comment on that. Because we do have to notice and we wouldn't make the time limit for the 20`h, it will be on the June 3`d meeting. At that time, it does require a conditional use for altering the flood plain. It does require interim use permit for the golf. It does require a wetland alteration permit and also they're asking for some variances to the code so there's about 6 items that we'll be doing. It's pretty complex even though it's a small use. So because we hadn't noticed all those issues, and to meet the legal requirement, it's going to be another cycle so it will not be on in 2 weeks but rather a month. We have had two very productive meetings trying to resolve some of the issues and I think we're moving in the right direction. We do think it's a reasonable use of the property but we want to make sure that we have a good enough understanding of the issues so we can appropriately mitigate the impacts of that. NEW BUSINESS: Aanenson: I had tentatively looked at putting on the comprehensive plan public hearing next, in two weeks. We do not have all the information back from the consultants doing the traffic study and the sewer comp plan final data. We are typing it into an easy to read format...make sure you have enough time to read through that before we call the public hearing. Right now we have that scheduled for the first item in June. That meeting. I propose to take as many meetings as we need to get through that. It may take two. It may take three. • APPROVAL OF MINUTES: Commissioner Blackowiak noted the Minutes of the Planning Commission meeting dated April 15, 1998 as presented. ONGOING ITEMS: Aanenson: As long as Phil's here, I'd like to let him tell you a little bit. We had a work session, he talked about the project he was going to do on Lake Susan and that's been underway and it's pretty exciting so maybe he can take a couple minutes and talk about it. Elkin: All right. You may have read in the paper,we've been,an ongoing project with Lake Susan this winter. We took out part of the problem with Lake Susan is there's very little game fish, very eutrophic or a lot of algae. We've been trying to get the algae under control so we did harvest 20,000 pounds of carp this winter along with 10,000 pounds of bullhead and nets were put out this spring and we have taken an additional 30,000 pounds of bullheads. They were all 19 Planning Commission Meeting - May 6, 1998 about the same size. Stunted growth. A quarter pound. We got those out. The alum treatment came. Before the alum treatment was done, we had a seci disc reading of 2 Y2 feet. A seci disc is the white, black and white disc you put in the water to judge the, you drop it in until it disappears and that determines, gives you a rough idea of how much algae clarity is in the water. A week after the alum treatment we could see all the way to the bottom of the lake, so 17 feet. So it did increase dramatically. Unfortunately, it hasn't maintained that. We don't know how much it's declined but with all the sun and very little rain, it's subject or conducive to a large number of algae growth so it's still very clear. You can, it's very noticeable if you walk around the lake how far you can see out compared to years past but we have noticed some more vegetation taking hold where it hadn't been before so it's looking good so we're real excited about that and keep, if you get a chance go down there and look off the dock and you can, it's a noticeable difference. Peterson: They were water skiing on Sunday. Elkin: All right, great. Peterson: With wetsuits on. Aanenson: If you go out to the pier, you can see to the bottom off the pier so I'd encourage you to take a walk, take a look at it. Elkin: If you also have a chance, we did some plantings on the wetlands across from Applebee's and we did that on Arbor Day. I was out there today and four lilies are coming up so it's, we have about 7 different types of species out there that we planted so that's another thing to look for so. Peterson: On the west side? Elkin: Both sides. All along, in the water. We planted from about the edge of the water to about 4 feet deep. And then we planted a strip of wild flowers along the whole perimeter of the wetland so. We need rain. Peterson: Not to wash it away though. Elkin: No, that's right. Peterson: Open discussion? Burton: Is there going to be any construction activity at all that you're aware of at the Villages? Is there anything, I just never see anything going on out there. Aanenson: Yeah. They do have the projects approved. They're in for building permits. Working through that. There's a couple issues that need to be ironed out as far as some utility stuff but. 20 Planning Commission Meeting- May 6, 1998 Blackowiak: You said they. Houlihan's or? Aanenson: Famous Dave's. Those two. Blackowiak: Oh Famous Dave's,okay. Brooks: Any of the retail sites coming in? Aanenson: I haven't talked to Vernelle about the leasing. How that's going but I don't think that they're ready for that phase yet. Two restaurants are coming in... Conrad moved, Peterson seconded to adjourn the meeting. All voted in favor and the motion carried. The meeting was adjourned at 8:17 p.m. Submitted by Kate Aanenson Planning Director Prepared by Nann Opheim 21
