The parcel contains a large Class A wetland and part of the Hwy. 212 right-of-way. The applicant. is applying for preliminary plat approval and a wetland alteration permit to allow development within 200 feet of a Class A wetland. The applicant is proposing to subdivide 78 acres into 75 single 1 family lots. The 78 acres contains 34 acres which will contain the 75 single family lots, 23 acres of outlots and 20 acres of street right-of-way. The outlots are as follows: 1 Outlot A 23, 339 square feet and is a remnant piece with a large - drainage ditch going through it located between what is shown as South Road and Lyman Boulevard. Outlot B 21,254 square feet and will be used as a drainageway directing drainage into the Class A wetland and is located at the end and north of the South Road cul-de-sac. 1 Outlot C 410, 659 square feet and contains the Class A wetland located at the southeastern section of the property. Outlot D 564,249 square feet and contains the Hwy. 212 right-of-way and remaining property to the north of Hwy. 212. The street right-of-ways proposed for the plat contain the internal streets as part of the subdivision, proposed Hwy. 212, Lake Riley Boulevard and Lyman Boulevard. The single family lots are divided into 5 blocks. The net density of the proposed subdivision is 2.2 units per acre which meets the maximum of 3.4 units per acre for residential low density. The lot sizes range from 15,000 square feet to 38,976 square feet with an average lot size of 19,969 square feet. , The subdivision has gone through several revisions to meet the Zoning Ordinance requirements and to accommodate the Class A wetland. With the exception of 3 lots, all of the lots meet the Zoning Ordinance requirements and there will be no detrimental impact to the Class A wetland which will be preserved in it's natural state. I I 1 1 Lake Riley Hills John Klingelhutz October 3, 1990 ' Page 3 As part of the preliminary plat, the Park and Recreation Commission ' is recommending dedication of Lots 21-26, Block 3, for park land and staff is recommending additional right-of-way along the North Road, West Road, Lake Riley and Lyman Boulevard. As a result of the additional right-of-way along Lake Riley and Lyman Boulevard, most likely the 3 lots between South Road and Lyman Boulevard will be lost and Lot 1, Block 5 will become unbuildable with less than 50 feet of lot depth. ' The Subdivision Ordinance requires a 300 foot offset for any local street from the intersection. To meet the requirements of the Subdivision Ordinance, the South Road would have to be shifted approximately 60 feet to the north to maintain the 300 foot offset. With the addition of right-of-way on Lyman Boulevard and shifting South Road to the north to meet the Subdivision Ordinance, there is ' a possibility that the applicant would also be losing lots north of South Road and that any remaining lots in that area would have the building pads shifted closer to the wetland and the 75 foot ' setback. Due to the potential of the 300 foot offset requirement pushing development closer to the wetland, staff is in favor of granting a variance to the ordinance requirement and feels that the 240 feet that is being provided will still provide enough safe ' access for vehicles entering and leaving the site. The preliminary plat has several conditions of approval, with the majority of the conditions are the basic conditions that apply to all plats and will not result in significant change to the preliminary plat. Therefore, staff is recommending approval of the preliminary plat and wetland alteration permit with conditions provided by staff. STREETS ' The subdivision is being provided with internal streets for an east/west future connection and access from Lyman Boulevard. The ' subdivision also proposes 3 cul-de-sacs to access lots adjacent to the Class A wetland. All of the streets provide the required 50 feet of right-of-way. Staff is recommending that the right-of-way ' for the North Road and the West Road be increased to 60 feet as they are anticipated to function as collector streets in the future. This width will also facilitate the installation of a sidewalk. The preliminary plat should note the right-of-way dimensions of all streets. The right-of-way for the cul-de-sacs are a 50 foot radius and the ordinance requires a 60 foot radius for an urban cul-de-sac. The preliminary plat should be changed to reflect this. In comparing the proposed plat submitted with the County half- sections, staff is unable to determine whether a 33 foot wide I t Lake Riley Hills f John Klingelhutz October 3, 1990 Page 4 1 segment of land along the north half of Lyman Boulevard has been previously acquired as right-of-way or acquired by easement. Nevertheless, preliminary results contained in the Eastern Carver county Transportation Study (excerpts attached) point to traffic volumes in excess of 7,400 ADT for this roadway. It's characteristics rank it as a minor arterial, Class II which will require a 120 foot right-of-way (60 feet on each side of the centerline) . It is therefore necessary that a 60 foot wide right- of-way be granted along the southern border of the proposed plat. This width would also allow incorporation of the future trail along Lyman Boulevard. The aforementioned transportation study designated the segment of Lake Riley Boulevard north of Lyman Boulevard also as a minor arterial, Class II roadway. Therefore, a 120 foot wide right-of- way will also be required for this road segment. This width would incorporate the future trail. Thus a separate trail easement would not be necessary. The street widths provided in the preliminary is shown to be a 32 , foot face curb to face curb. This is equivalent to the city standard of a 35 foot back up curb to back up curb for an urban collector street. This standard is applicable to the North Road and West Road. The applicant should be advised that the Loop Road, South Road and South Cul-de-sac may be reduced in width to a 31 foot back up curb to back up curb if so desired. The intersection of South Road and West Road is located approximately 240 feet north of Lyman Boulevard. The ordinance requires that a minimum centerline offset distance of ' intersections be 300 feet. Therefore, the applicant will have to shift the intersection of South Road and West Road approximately 60 feet or receive a variance. The location of the South Road provides lots with adequate area for development without impacting the wetland. As previously stated, the city will be requiring an additional 27 feet along Lyman Boulevard to accommodate necessary road improvements. As a result, the applicant will probably loose 3 lots between Lyman Boulevard and South Road. Most likely shifting South Road further to the north, in addition to providing additional right-of-way will result in the loss of more lots and pushing other lots closer to the wetland. Since it will result in a more closer impact to the wetland due to the proximity of the homes and the street has an offset of 240 feet, staff would be in favor of a variance and allow South Road an offset of at least 240 feet. The City Engineering Department has agreed to support this alternative. ' Initially, the only access to the site will be from Lyman Boulevard. When future development occurs around this site, it is 11 11 Lake Riley Hills John Klingelhutz October 3, 1990 Page 5 anticipated that North Road will be extended both to the east and west and provide additional access points to the subdivision. Until the North Road is extended in the future, temporary cul-de- sacs will be required to be installed at the ends of the North Road. Barricades will also be required to be installed at the ' temporary cul-de-sacs and they will be signed designating them to be only temporary and a future road extension. Outlot D, which is being separated from the rest of the property by the improvements ' for Hwy. 212, is currently designated as unbuildable and will be platted in the future. At that time street connections to the site will be reviewed. ' There currently exists a private driveway along the easterly boundary of the proposed plat which services a house located in the northeast corner of the site. The residence driveway was constructed via a dike which bisects the wetland area. It is anticipated that the proposed Trunk Highway 212 improvement will require the removal of this house. In order to convert the wetland ' area back to it's original state as one whole wetland, staff is recommending that the gravel driveway be removed. Such efforts should be coordinated between the Department of Natural Resources, ' Corps of Engineers and Fish and Wildlife Service and with the City of Chanhassen. In preliminary discussions with DNR and Fish and Wildlife, it was stated that it would be preferred to have the original wetland re-established as one complete wetland. The plat ' is proposing to continue to service the house with the existing driveway through what is now being proposed as Lot 14, Block 2. A driveway easement shall have to be provided over Lot 14, Block 2 ' for access to the existing house. Since the driveway will be crossing over the end of North Road, the removal of the current dirt road through the wetland will not remove access to the house since access can now be obtained from the new North Road as part of ' the subdivision. UTILITIES ' A study has been authorized by the City Council, at the request of the applicant, to determine the feasibility of servicing this area ' with a watermain and sanitary sewer. A condition of this authorization was for the applicant to submit a $10,000 letter of credit or cash escrow to guarantee payment of expenses associated with the feasibility study. The security required has not yet been received and as a result, the study has not been initiated. The applicant does not want to submit a letter of credit or cash escrow until the application has gone through the Planning Commission in ' case it is recommended for denial or results in such extensive changes that the project is no longer feasible. Once it is clear that the project will move ahead, the applicant will submit the letter of credit for the feasibility study to be initiated and 1 I Lake Riley Hills I John Klingelhutz October 3, 1990 Page 6 ' understands that there will be no final plat approval until such a feasibility study is completed and it is determined how the watermain and sanitary sewer will be extended to the site. Staff is recommending that the applicant's engineer submit the flow calculations for the sanitary sewer system to verify pipe capacity and minimum score velocities through all of the sewer segments within the proposed subdivision. Staff is also recommending that the applicant's engineer verify that the existing lift station and 4" forcemain sewer to facilitate this subdivision is adequate in size and capacity. It should be noted that the entire development is proposed to be serviced by gravity sewer, however, the connection point for this system will be in the vicinity of Lyman Boulevard and Lake Riley Road and immediately upstream from an existing lift station and 4" forcemain. EASEMENTS All of the sanitary sewer and storm sewer extensions, will require the respective drainage and utility easements and shall be denoted as such on the plat. The proposed detention ponds and corresponding access ways will require easements. The temporary cul-de-sac at both ends of North Road will also require temporary easements to cover the portions outside of the platted right-of-way and shall exist until such time that the road extensions are constructed and the cul-de-sacs are removed. GRADING The plan is proposing to grade the southern two thirds of the site. , The final grading will be similar to the existing topography on the site which drains primarily southeast into the wetland area. The steepest slopes will be found in the rear yard areas of the lots surrounding the wetland area, specifically, Lots 30-35, Block 3, and Lots 4-8, Block 3. Special slope stabilization methods such as wood fiber blankets and Type III erosion control will be required in these areas. The applicant was requested to obtain and provide information from MnDOT detailing the current plan elevations for the corresponding segment of future roadway for the Hwy. 212 improvement. This information has not been submitted, however, some slope grading is shown on the plan. Staff stresses the need for the applicant to submit the requested information on the future Trunk Highway 212 • Project to verify the compatibility related to grades and elevations of these two projects. Staff recommends that the applicant also provide some sort of noise abatement measures such as earth berming immediately south of proposed T.H. 212 alignment. Staff has received a letter from MnDOT stating that the I I 11 Lake Riley Hills John Klingelhutz October 3, 1990 Page 7 improvements of Hwy. 212 and the subsequent proposal for a single family lot subdivision adjacent to it will require some form of noise abatement. MnDOT further stated that such improvements would not be paid for by MnDOT and are the responsibility of the applicant and/or City. ' DRAINAGE The majority of the site drains southeast into the wetland area. Detention ponds are proposed to be constructed in an effort to maintain the pre-developed runoff rate for the site. Staff is requesting that the applicant's engineer review the total capacity ' of these ponding basins needed to meet the predicted retaining requirements. Also, the configuration and location of the pond are such that access to the pond by the city for maintenance appears to ' be very difficult, if not impossible at all. Staff is recommending that the applicant provide a plan showing designated access points to these ponding basin areas and verifying that they will be able ' to be serviced by the city crews when necessary. Staff has also asked the applicant to verify the location of these ponding areas on site since they appear to be very close to the wetland edge and may in fact intrude upon some of the existing wetland vegetation. ' If such is the case, staff would be recommending that the ponding areas be relocated so that there is no disturbance to the existing wetland area. One suggestion would be to relocate the ponding area to a more central location such as between the South cul-de-sac and the loop cul-de-sac where they can be more easily accessed and maintain more distance from the wetland rather than being located ' completely around the wetland edge. Staff is also requesting that the applicant provide information on the existing drainage facilities such as culverts to and from the site. Specifically, the culvert under Lyman Boulevard which will intersect the South Road cul-de-sac and the outlet culvert to the wetland under Lake Riley Road. Staff anticipates a potential drainage problem with the westerly temporary cul-de-sac for North Road. This portion of the existing site did not previously drain off site to the west. The proposed street grading plans shows this cul-de-sac and the adjacent 100 ' feet of North Road to not be serviced by storm sewer. Staff recommends that this area be reviewed for storm sewer service. If storm sewer is not feasible, some sort of interim drainage proposal ' must be submitted that facilitates this lower area not being serviced by storm sewer. Staff suggests one alternative being a temporary overland drainage, via a swale, to the proposed ditch swale to the rear of Lots 10-14, Block 1. 11 I Lake Riley Hills I John Klingelhutz October 3, 1990 Page 8 I EROSION CONTROL The plans submitted display Type III erosion control over the entire area bordering the wetland area. Staff is recommending additional erosion control north of North Road. As mentioned previously, wood fiber blankets will be required as slope stabilization measures for all of the rear lots bordering the wetland area and on all the areas where slopes are 3:1 or greater. Silt fence erosion control should be installed around any and all proposed detention ponds on the project. The entire site should be reseeded and mulched immediately following completion of the grading operation. LANDSCAPING The applicant has shown on Sheet 2 of the plans areas of vegetation. Staff has requested that the applicant provide detailed information on the areas of vegetation as to the type of tree and size. The City will require tree removal plans for those lots with significant vegetation such as Lots 10-16, Block 3 and the city will require replacement for trees with a caliper of 4 and over (other than species of shrub trees such as box elder) . PARK AND RECREATION On September 25, 1990, the Park and Recreation Commission reviewed the Lake Riley Hills project (Attachment #2) . The Park and Recreation Commission recommended that Lots 21-26, Block 3 be dedicated as parkland. As part of the dedication, the applicant will reconfigure lot lines to allow for a contiguous southerly border and prepare the site according to a grading plan provided by the City. It was further recommended that the applicant construct a 5 foot wide concrete sidewalk along North Road and West Road and provide a 20 foot wide trail easement along Lake Riley Boulevard and Lyman Boulevard. In return for these requirements, the applicant will receive a $410 credit on park fees per unit and 100% credit on trail fees. The remaining $90 of park fees per unit will be collected as part of the building permit process. The Park and Rec Commission also stated that the park and trail requirements were for the parcel south of Hwy. 212 and that requirements for the parcel north of Hwy. 212 will be reviewed at the time it is .developed. The Park and Rec Commission has not determined which side of the street the sidewalk should be located and this will be determined by the Engineering Department. Also, the requirement of a 20 foot wide trail easement along Lake Riley Boulevard and Lyman Boulevard will not be necessary if the additional right-of-way, as requested by staff along both Lyman and Lake Riley Boulevard, is provided. I I II Lake Riley Hills John Klingelhutz October 3, 1990 I Page 9 The additional right-of-way requested by staff will also Iaccommodate any trail improvements along the roads. The following is a table of the lots and their compliance with the Zoning Ordinance. ICOMPLIANCE TABLE - LOT SIZES II The following are lots which do not comply with the Zoning Ordinance AREA WIDTH DEPTH IREQUIREMENTS (15, 000) (90' ) (125' ) BLOCK 1 Lot 11 26,840 89* 297 I BLOCK Lot 12 26,415 89* 297 4 Lot 5 16,841 147 113** 1 BLOCK 5 Lot 1 28,704 460 50** * Lot must be adjusted to provide 90' of lot frontage at the lot IIline ** Lot must be adjusted to provide 125' lot depth. IILot 5, Block 4 only has a depth of 113 feet which does not meet the ordinance requirements of a lot depth of 125 feet. The lot I configuration in Block 4 must be adjusted to provide Lot 5, Block 4 with the required lot depth. Several of the lots do not have the 90 feet of street frontage at the lot line but these are located along the outside of a curve and the ordinance allows for the 90 I feet width to be provided at the 90 foot setback. All of the lots in question do meet the 90 feet at the 30 foot setback. Lot 10, Block 1 is a triangular shaped lot and staff is recommending that I this lot be reconfigured to provide four sides to prevent any difficulty in meeting setbacks when the building permit is applied for. Lot 1, Block 5, contains a 28,704 square foot lot located U adjacent to Lake Riley. As will be covered in this report, future improvements to Lake Riley Boulevard requires 27 feet of additional right-of-way on both sides of the street. The additional 27 feet taken from Lot 1, Block 5 essentially makes it an unbuildable lot 1 with less than a 50 foot depth. Therefore, Lot 1, Block 5 should be designated as an outlot. IWETLAND ALTERATION PERMIT The proposed subdivision contains a large Class A wetland located in the southeast corner of the site. The wetland is of high II I Lake Riley Hills I John Klingelhutz October 3, 1990 Page 10 I quality and is approximately 91 acres in size. The Class A wetland • is also a protected wetland by the DNR. Any activity below the ordinary high water elevation, which alters the course, current or cross section of protected waters or wetland is under the jurisdiction of the DNR and may require DNR protected water permit. The applicant met on site with the DNR to determine the OHW, which is now set at 864 .7. Upon site inspection, it was determined that there was a fringe of wetland vegetation beyond the ordinary high water mark at approximately 866 elevation. Therefore, the wetland boundary shall be determined as the 866 elevation and will be protected by a drainage and utility and conservation easement and also shown as a "wetland" on the final plat. The applicant is providing a storm water sedimentation basins to prevent storm water from being directed directly to the wetland. This will prevent sedimentation and water level bounces that are detrimental to the basin's wildlife values and water quality. As mentioned previously, staff is recommending that the applicant stake the extent of the ponding areas on site to verify that the wetland fringe vegetation is not being altered or disturbed by the proposed ponding areas. Once it is ensured that the ponding areas are not impacting the wetland vegetation, staff is comfortable with the subdivision in that the proposal will not be impacting the wetland and will actually be resulting in some improvement once the gravel driveway dividing the wetland in two is removed. The applicant has adjusted the lot areas adjacent to the wetland I since the original submittal to provide for the 75 foot wetland setback. The majority of the lots adjacent to the wetland do provide adequate area for a single family residence and an attached deck or porch. Lots 34 and 35, Block 3 and possibly Lot 36, Block 3 will not have adequate room for a house and a deck. As done with previous subdivisions with wetlands, staff will recommend a condition that the applicant, as part of the development contract, record restrictions against each lot stating that there is a 75 foot setback from the wetland elevation of 866 contour and that this elevation shall be shown on all lot surveys when a building permit is submitted. If porch or patio doors are provided on the house plans, the lot survey will show how a deck can meet the required wetland setback. The proposed ponding areas adjacent to 111 the wetland will be shallow ditches which will most likely take on a wetland quality with wetland vegetation, Therefore, staff is recommending that in addition to the drainage easement that will be covering the ponding areas, a conservation easement be located over the ponding areas and wetland to ensure that the areas are not altered. I 1 I 11 Lake Riley Hills John Klingelhutz October 3, 1990 Page 11 RECOMMENDATION - PRELIMINARY PLAT Staff recommends the Planning Commission adopt the following motion: ' "The Planning Commission recommends approval of Preliminary Plat #90-10 for Lake Riley Hills as shown on the plans dated September 4, 1990, with a variance to permit a 240 foot offset between the ' intersection of South Road and Lyman Boulevard, with the following conditions: 1.

Approval is conditioned upon compliance with all conditions of ' the Wetland Alteration Permit. 17. The applicant shall look into the feasibility of turn lanes and turn lanes shall be added if city staff feels it is ' appropriate and necessary for safety to get people in and out of the new subdivision. ' 18. Outlot A in Block 3 shall be under ownership of adjoining properties. 19. Plans shall be drawn and submitted to city staff for approval to get a berm and screening along Lyman Boulevard between Lot 1, Block 1 and between Lots 1 and 2, Block 3. ' All voted in favor except for Erhart who opposed the motion because he did not believe that we have adequate assurances that services, both the transportation and sewer are adequate to see this as a positive development. I ■ I I Lake Riley Hills I John Klingelhutz October 3, 1990 Page 14 , CITY COUNCIL RECOMMENDATION Staff recommends the City Council approve Preliminary Plat for Lake Riley Hills Addition with staff's 15 conditions and the four additional conditions from the Planning Commission. RECOMMENDATION - WETLAND ALTERATION PERMIT In summary, the proposal will not be negatively impacting the Class I A wetland located on the site, and in fact, if the existing dirt driveway bisecting the wetland into 2 is removed, it will actually ultimately improve the wetland. Therefore, staff is recommending that the Planning Commission adopt the following motion: "The Planning Commission recommends approval of a wetland alteration permit for Lake Riley Hills subdivision as shown on plans dated September 4, 1990, with the following conditions: 1. The applicant shall provide a drainage, utility and a conservation easement over Outlot C and the proposed ponding areas and that the 866 contour shall be the edge of the protected wetland. I 2. Any surveys for lots adjacent to the Class A wetland will provide the 866 elevation with verification that the home and any further improvements such as porches or decks will maintain the 75 foot setback from the 866 contour. 3. A development contract will be recorded against the property and will protect both the Class A wetland and the ponding areas adjacent to the wetland with a conservation easement and not allow any alteration to these areas. " ' • PLANNING COMMISSION UPDATE On October 3, 1990, the Planning Commission recommended approval of ' the wetland alteration permit with staff's conditions and added the following condition: 4. The wetland alteration approval is conditioned upon compliance with all conditions of the preliminary plat #90-10. CITY COUNCIL RECOMMENDATION Staff recommends the City Council approve Wetland Alteration Permit request for Lake Riley Hills Addition with staff's 3 conditions and adding condition #4 as recommended by the Planning Commission.

This parcel of land is characterized by a rolling terrain , randomly spersed stands of trees and a large wetland area located in the southeast corner. The present use of this land is agricultural with field grasses and some row crops. The current zoning for this parcel is mixed low-density II residential and single-family. The proposed zoning would be a composite of single-family residential for the southern two-thirds of the property and high-density residential for the II northern one-third. A large strip of land located through the northern half of the site has been designated as a corridor for the future Trunk Highway 212 improvement project. The preliminary plat submitted proposes to plat the southern II two-thirds of the site as residential single-family lots with the northern portion, in and around the Trunk Highway 212 corridor , being platted as an outlot. I Grading The plan submitted proposes to grade the southern two-thirds of I the site. The grading scheme is proposed to be similar to that existing which drains primarily southeast into the wetland area. The steepest resulting slopes will be found on the rear yard I areas of the lots surrounding the wetland area. Special slope stabilization methods such as wood-fiber blankets and Type III erosion control will be required in these areas. II II II 1 1 Jo Ann Olsen September 25 , 1990 Page 2 In reviewing the grading plan , one major area of concern has arisen. This concern relates to the interfacing of this development with the proposed future Trunk Highway 212 highway improvement . The applicant was requested to obtain and provide information from MnDOT detailing the current right-of-way and ' plan elevations for this corresponding segment of future roadway. This information has not been submitted to date; however, some slope grading is shown on the plan. Staff stresses the need for the applicant to submit the requested information on the future ' Trunk Highway 212 project to verify the compatibility of these two projects related to right-of-way, grades and elevations . Staff recommends that the applicant also provide some sort of noise abatement measures such as earth berming immediately south • of the proposed Trunk Highway 212 alignment. ' The property lying north of the Trunk Highway 212 corridor, as mentioned previously, will be platted as an outlot and proposed for future high density residential zoning. No grading is proposed in this area at this time. A complete site plan review of this area will be made when a future proposal is submitted. Drainage ' As mentioned previously , the majority of the existing site and the proposed site drains southeast into the wetland area. A preliminary storm sewer plan has been submitted for this ' subdivision . A review has been made and the corresponding detail comments and corrections have been outlined on a plan set to be returned to the applicant ' s engineer for revisions. Storm sewer ' calculations and runoff rate requirements have also been submitted for review. The applicant will also need to submit these grading plans and drainage information to the Watershed ' District for review and approval . Detention ponds are proposed to be constructed in an effort to maintain the predeveloped runoff rate for the site. From ' preliminary review, 'staff is requesting the applicant' s engineer to review the total capacity of these ponding basins needed to meet the predicted retainage requirements. Another very ' important area of concern related to the detention ponds involves acquiring access to these ponds and their corresponding outlet structures for maintenance purposes . Staff recommends that the applicant provide a plan showing designated access points to ' these ponding basin areas . • Staff also requests that the applicant provide information on existing drainage facilities such as culverts to and from the site. Specifically, the culvert under Lyman Boulevard which will intersect with the South Road cul-de-sac and the outlet culvert for the wetland area under Lake Riley Road. I I Jo Ann Olsen September 25 , 1990 Page 3 Staff anticipates a potential drainage problem with the westerly temporary cul-de-sac for North Road. This portion of the existing site did not previously drain off-site to the west. The proposed street grading plan shows this cul-de-sac and the adjacent westerly 100 feet of North Road to not be serviced by storm sewer. Staff recommends that this area be reviewed for storm sewer service. If storm sewer is not feasible, some sort of interim drainage proposal must be submitted that facilitates this lower area not being serviced by storm sewer. Staff suggests one alternative being a temporary overland drainage, via a swale, to the proposed ditch swale through the rear lots of Lots 10 through 14 of Block 1 . Erosion Control ' The plans submitted display Type III erosion control over the entire area bordering the wetland area. Staff is recommending the addition of erosion control on the easterly end of the site north of North Road and on the westerly end of the site north of North Road. As mentioned previously, wood-fiber blankets will be I required as a slope stabilization measure for all of the rear lots bordering the wetland area and on all the areas where slopes are 3:1 or greater . Silt fence erosion control should be installed around any and all proposed detention ponds on the project. The entire site should be re-seeded and mulched immediately following the completion of the grading operation. Streets All of the streets within this proposed subdivision have a right-of-way scale dimension of 50 feet. Staff recommends that right-of-way for North Road and West Road be increased to 60 feet as they are anticipated to function as collector streets in the future. This width will also facilitate the installation of the required sidewalk. The dimensions for all streets shall be noted on the plat to confirm this . The right-of-way for the cul-de-sacs scale to be approximately 50-foot radiuses . Staff notes that the current radius of right-of-way for an urban cul-de-sac is to be 60 feet and that the applicant shall make this appropriate change. 1 A review of the street plan has been performed and corresponding detail recommendations have been noted on plan set to be returned to the applicant's engineer for revision. Street widths on the plans are shown to be 32 feet face-of curb to face-of-curb. This is equivalent to the City standard of 35 feet back-of-curb to back-of-curb for an urban collector street. While this standard is applicable to North Road and West Road, the applicant should be advised that the Loop Road, South Road and south cul-de-sac may be reduced in width to 31 feet back-of-curb to back-of-curb. I I 11 Jo Ann Olsen September 25 , 1990 Page 4 Staff would also like to note that the intersection of South Road and West Road will have to be shifted approximately 60 feet to ' the north. The centerline for South Road is located approximately 240 feet north of Lyman Boulevard. City Ordinance requires that the minimum centerline offset distance between intersections be 300 feet. Initially, the only access to the site will be via Lyman Boulevard. When future development occurs around this site, it ' is anticipated that North Road will be extended both to the east and to the west and provide additional access points to this subdivision. As mentioned previously, temporary cul-de-sacs will ' be installed at the current limits to North Road. Staff also recommends that barricades be installed at the ends of these cul-de-sacs and that they be signed designating them to be temporary pending future road extensions . The portion of the property north of the Trunk Highway 212 corridor to be platted at this time as an outlot will have future ' access from Tigua Lane. There currently exists a private driveway along the easterly ' boundary of this subdivision which services a farmhouse located in the northeast corner of the site. This driveway was constructed via a dike which bisects the wetland area. It is anticipated that the proposed Trunk Highway 212 improvement will require the removal of this farmhouse. In an effort to reunite the two wetland areas on either side of this private driveway, staff is recommending that the applicant pursue the possibility ' of removing this driveway and dike barrier by contacting and coordinating with the Department of Natural Resources. A temporary access to this farmhouse could be acquired along the property line between Lot 14 and Lot 13 of Block 2 until such ' time that the Trunk Highway 212 improvement project removes these structures . ' Utilities A review has been made of the sanitary sewer and watermain plans ' submitted in conjunction with the proposed subdivision. At the present time, a feasibility study has been authorized by the City Council, at the request of the applicant, to determine the feasibility of servicing this area with watermain and sanitary ' sewer . A condition of this authorization was for the applicant to submit to the City a $10,000 letter of credit or cash escrow to guarantee payment of expenses associated with this study (see ' attachment) . This security has not been received to date and as a result the study has not been initiated. Until the results of this study are known, it will be inappropriate to make any final approval of the subdivision proposal . I I Jo Ann Olsen September 25 , 1990 Page 5 Staff recommends that the applicant's engineer submit the flow calculations for the sanitary sewer system to verify pipe capacity and minimum score velocities through all the sewer segments within this proposed subdivision. Staff is also recommending that the applicant 's engineer verify that the existing lift station and 4-inch forcemain sewer to facilitate this subdivision is adequate in size and capacity. It should be noted that the entire development is proposed to be serviced through gravity sewer; however, the connection point for this system will be in the vicinity of Lyman Boulevard and Lake Riley Road immediately upstream from an existing lift station and 4-inch forcemain . Sidewalk 1 The applicant will be required to install a 5-foot wide concrete sidewalk along the boulevard area on the south side of the , proposed North Road and east side of West Road. The revised plan submittal should include this information. Easements ' All of the sanitary sewer and storm sewer extensions through the lot areas of the site will require the respective drainage and utility easements and shall be denoted as such on the plat. The proposed detention ponds and corresponding access ways will require pertinent easements . Staff also notes that the temporary cul-de-sacs at both ends of North Road will require temporary easements to cover the portions outside of the platted right-of-way and shall exist until such time that the road extensions are constructed and cul-de-sacs removed. In comparing the proposed plat submitted with the County half-sections , staff is unable to determine whether a 33-foot wide segment of land along the north half of Lyman Boulevard has been previously acquired as right-of-way or acquired by easement. Nevertheless , preliminary results contained in the Eastern Carver County Transportation Study (excerpts attached) point to traffic volumes in excess of 7 ,400 ADT for this roadway. Its characteristics rank it as a minor arterial, Class II which will require a 120-foot right-of-way (60 feet on each side of centerline ) . It is therefore necessary that a 60-foot wide right-of-way be granted along the southern border of the proposed plat. This width would also allow incorporation of the future 1 trail along Lyman Boulevard. The aforementioned transportation study designated the segment of Lake Riley Boulevard north of Lyman Boulevard as also a minor arterial, Class II roadway. Therefore, a 120-foot wide right-of-way will also be required for this road segment. This width would incorporate the future trail. Thus, a separate trail easement would not be necessary. 1 I 11 Jo Ann Olsen September 25 , 1990 Page 6 As mentioned previously , a temporary driveway easement will need to be acquired between Lots 13 and 14 of Block 2 in order to 1 provide a temporary access for the existing farmhouse. Recommended Conditions 1 . Further processing of this application cannot be made until the findings of the feasibility study are known and the City Council takes appropriate action to provide municipal water service to the site. 2 . The applicant shall provide current plan right-of-way, grade ' and elevation information for the future Trunk Highway 212 improvement for the segment of roadway through this subdivision. Noise abatement measures such as earth berming shall be shown on the plan along the southern border of the corridor . 3 . The applicant shall provide existing drainage facility ' information to and from the site (specifically the culvert under Lyman Boulevard) . ' 4 . The applicant ' s engineer shall verify the capacity of the proposed detention ponds and shall provide adequate access to these ponds for maintenance purposes . 5 . The storm drainage plan shall be modified to incorporate the runoff from the westerly temporary cul-de-sac on North Road. 6 . The applicant shall submit these plans to the Watershed District, PCA and Health Department for review and approval . ' 7 . The applicant' s engineer shall make the necessary changes as outlined on the remitted plan sheets reviewed dated September 24 , 1990 . 8. The applicant shall provide a registered engineer' s report on soils , footings and structural design and certification of a registered engineer verifying that the grading and drainage has been constructed according to the approved plans prior to the issuance of building permits. 9 . Wood-fiber blankets and Type III erosion control will be ' required for slope stabilization of all the rear lots bordering the wetland area and on all other areas where slopes are 3:1 or greater. 10 . The right-of-way dimension for North Road and West Road shall be 60 feet in width and the right-of-way dimension for the cul-de-sacs shall be a 60-foot radius. I I Jo Ann Olsen September 25 , 1990 1 Page 7 11 . The temporary cul-de-sacs on North Road shall be barricaded , I and signed designating them to be temporary in lieu of future road extensions . 12. The applicant shall grant a 60-foot wide right-of-way for Lyman Boulevard along the southern border of the plat and a 120-foot wide right-of-way along Lake Riley Boulevard. I 13 . The applicant shall contact the Minnesota Department of Natural Resources to investigate the possibility of removing the private driveway dike along the eastern borderline of the plat. 14 . The applicant shall construct sidewalk along the southern ' boulevard area of North Road and along the eastern boulevard area of West Road. 15 . The applicant shall provide the necessary drainage and i utility easements for the proposed storm sewer, sanitary sewer, detention pond and access areas within the plat. 16 . The applicant shall enter into a development contract with the City and provide the necessary financial securities associated with the project. I ktm Attachments 1 .

Box 89 Chaska , MN 55318 Re: Feasibility Study for Watermain Extension Project No. 90-10 Dear Mr. Klingelhutz : This letter is in follow-up to the City Council action of July 23 , 1990 wherein they accepted your request for a feasibility study to evaluate watermain extension to your property located in the northeast quarter of Section 24 near Lake Riley. The feasibility study was also directed to evaluate the extension of sanitary sewer service to this area. City Council conditioned their approval upon receipt of a $10,000 letter of credit or cash 1 escrow from you to guarantee payment of the expenses associated with this study. In discussion with Mr. Bill Engelhardt, this has verbally been communicated to you earlier but I thought I would document in writing that this study will not be initiated until such time as the City receives the financial security as required. I would anticipate the study would take from four to six weeks to be completed so you may want to factor this into your schedule. 1 If you have any questions in the meantime, please feel free to call .

Mr. John Klingelhutz , the applicant for this plat, was present at this meeting. Upon conclusion of their discussion the Commission took the following action. Commissioner Mady moved, Commissioner Robinson seconded ' to require Lots 21, 22 , 23 , 24, 25 and 26, Block 3 , Parcel 2 be dedicated as park land. As part of the dedication, the applicant will reconfigure lot lines to allow for a contiguous southerly border and prepare the site according to a grading plan provided by the City. It is further recommended that the applicant construct a 5 ft. wide concrete sidewalk along North Road and West Road and provide a 20 ft. wide trail easement along Lake Riley Road and Lyman Boulevard. In return for these requirements the applicant will receive a $410. 00 credit on park fees per unit and a 100% credit on trail fees. The remaining $90. 00 of the park fee per unit will be collected as part of the building permit process. All voted in favor and the motion carried. I I have attached a copy of the report presented to the Commission for this item. Your assistance in seeing that the wishes of the Park and Recreation Commission are fulfilled is appreciated. Lastly, it is important for all parties involved to realize that these park and trail requirements are for Parcel 2 only. Requirements for Parcel 1 would be addressed at the time it is developed. . 1 I CITY OF PRC DATE: 9-25-90 CC DATE: CUAHAEH r .' � �I STAFF REPORT il , PROPOSAL:P L: To subdivide 78.24 acres into 75 single family lots and 4 outlots.

Bandimere II f Park and Recreation Commission September 25, 1990 Page 3 dedication. Mr. John Klingelhutz, the applicant, has also been in contact with me concerning this subdivision. Mr. Klingelhutz initially was somewhat opposed to the dedication of park land. In concluding our conversation, he said he would like to review the proposal , but seemed open to the issue of land dedication. In conversations with both Mr. Klingelhutz and Engelhardt and Associates, the topic of sidewalks along North Road and West Road was discussed. It is apparent that pedestrian walkways in these locations would prove beneficial . Mark Koegler also mentioned the need for sidewalks along these routes when reviewing this new location for the proposed park. RECOMMENDATION Progress in solidifying negotiations to meet the recreational needs created by this development is significant. City Code allows for a requirement of 2 . 76 acres of land be dedicated for park purposes in the development of parcel II. Parcel I will be considered separately in the event of future development. Lots 21, 22 , 23 , 24 , 25 and 26 consist of 2 . 26 acres which represents 82% of the requirement. Therefore, it is recommended that the Park and Recreation Commission require Lots 21 , 22 , 23 , 24 , 25 and 26, Block 3 , Parcel II be dedicated as park land. As part of this dedication, the applicant will prepare the site according to a grading plan provided by the city. In return for this dedication, the applicant will receive a $410. 00 credit on park fees for each lot. The remaining $90. 00 per lot to be collected as part of the - building permit process. It is further recommended that the applicant construct a 5 ft. wide concrete sidewalk along North Road and West Road in lieu of trail fees. 1 1 1 I II ..

IAugust 8, 1990 IMs. JoAnn Olsen City of Chanhassen 1 690 Coulter Drive Box 147 Chanhassen, MN 55317 II Dear Ms. Olsen: RE: LAKE RILEY HILLS, LAKE RILEY (10-2P) ,2P) , CITY OF CHANHASSEN, CARVER COUNTY IIWe have reviewed the site plans (received July 9, 1990) for the above-referenced project (WZ NE4, Section 24, Township 116 North, iRange 23 West). and have the following comments to offer: 1) Protected wetland 10-213W (shown as outlot B) is on the 1 proposed site. Any activity below the ordinary high water elevation (OHW) , which alters the course, current, or cross-section of protected waters or wetlands, is under the jurisdiction of the DNR and may require a DNR protected waters II permit. No official OHW has been established for wetland 10-213W. Please contact this office if there is any question about whether proposed activities will be within protected I wetland 10-213W and we can make arrangements to estimate or officially determine, if necessary, the OHW. 2) DNR protected wetland 10-213W should be labeled as such in I future plans or plats and the OHW, if available, should be noted. I 3) The project is within the shoreland district of Lake Riley (10-2P) , which is classified as recreational development. The City should ensure that the project is consistent with the I local shoreland management ordinance. It does appear that the minimum lot sizes are met in the proposed plan. 4) There should be some type of easement, covenant or deed I restriction for the properties adjacent to the wetland areas. This would help to ensure that property owners are aware that the DNR and the Corps of Engineers have jurisdiction over the II area and that the wetlands cannot be altered without appropriate permits. IIRECEIVED AN EQUAL OPPORTUNITY EMPLOYER AUG 1 0 1990 ICITY OF CHANHASSEN I JoAnn Olsen August 8, 1990 Page Two 1 5) It appears that the stormwater is being routed directly to wetland 10-213W. Stormwater sedimentation/treatment basins, or other appropriate stormwater treatment features, should be included in the plan. If stormwater is routed directly to the wetland it can cause sedimentation and water level bounces that are detrimental to the basin's wildlife values and water quality. 6) If construction involves dewatering in excess of 10,000 gallons per day or 1 million gallons per year, the contractor will need to obtain a DNR appropriation permit. You are advised that it typically takes approximately 60 days to process the permit application. 7) Appropriate erosion control measures should be taken during the construction period. The Minnesota Construction Site Erosion and Sediment Control Planning Handbook (Board of Water & •Soil Resources and Association of Metropolitan Soil and Water Conservation Districts) guidelines, or their equivalent, should be followed.

We find the plat acceptable for further development with consideration of the following comments: •I - We request the developer to dedicate access control along the proposed CSAH 212 corridor prior to approval of the final plat. I - Residential development is a very sensitive land use. Future noise levels are expected to violate state standards. The Minnesota.Pollution Control Agency will most likely require that noise abatement be constructed to Imitigate noise pollution from TH 212. The City and developer should be aware that Mn/DOT will not provide noise abatement for new development I adjacent to corridorsthat have been officially mapped. We believe the City and developer should plan to provide noise abatement along TH 212 for this development. I - The proposed letting date for TH 212 in this area is fall of 1996. I - This development impacts DNR wetlands. DNR, Corps of Engineer and Riley-Purgatory-Bluff Creek Watershed District permits will be required.

BOX 147 • CHANHASSEN, MINNESOTA 55317 II (612) 937-1900 • FAX (612) 937-5739 1 August 17, 1990 1 t 1 Mr. Owen Carlson Engelhardt and Associates 1107 Hazeltine Boulevard Chaska, MN 55318 1 Dear Owen: The Planning and Engineering staff have made a review of the 1 amended plans for Lake Riley Hills. Previously, staff submitted comments on the first draft requiring additional information. The following is a list of items which still need to be provided before a complete plan reveiw can be conducted: 1. The ordinary high water mark of the wetland must be determined. The DNR can work with you to determine the OHWM. 2. Soil boring information is still required. 3. Erosion control should be shown as Type III, not Type I. 4. Temporary cul-de-sacs should be shown on all street ends. 5. Storm water calculations verifying surface water discharge is retained to predeveloped rate for 100 year, 24 hour storm. 1 6. Tie the site into Highway 212 improvement. 7. The Fire Department needs the following information: 1 a. Fire hydrants shown with '300 foot spacing. b. City approved street names. 1 c. Through streets with relation to West 86th Street. 8. Need record information on all existing city utilities that 1 are proposed to be connected to. 9. Provide information on all existing drainage facilities and 1 1 I Mr. Owen Carlson 11 August 17, 1990 Page 2 culverts on and immediately adjacent to the site. 10. Provide tree removal plan detailing what type and size of trees which will be removed. There is a stand of trees around the south and southeast side of the wetland which need to be included. General comments: 1. The slopes around the ponding areas and wetland are very steep ' and will require slope stabilization including wood fiber blanket. Staff feels the slope is too steep and lots are too close to the wetland resulting in back yards which cannot be ' used by the homeowner. For example, Lots 34 and 35, Block 3, will not be permitted decks due to the wetland setback. 2. The proposed ponding areas do not provide the City access points for maintenance. Combining the ponding areas into a more central accessible site might be preferred. Please submit revised plans with the above information and the City will then proceed with the application.

Dennis Baker 9219 Lake Riley Blvd. Jo Ann Olsen presented the staff report on this item . Vice Chairman ErharII called the public hearing to order .. Erhart: Is the applicant here? I Bill Engelhardt: Mr . Chairman, members of the Planning Commission , I 'm I Bill Engelhardt . I 'm representing John Klingelhutz tonight on a project he 's proposed . Erhart: Bill , can you hang on just one minute . Steve , what 's your I question? Emmings: I guess I 've got a problem looking at a new plan tonight . Unles you tell me that everything else in the staff report stays exactly the same except for 1 or 2 items . Olsen: I think what they 're just showing you is that they've adjusted the' lot lines to meet those requirements . Emmings: When we do a motion here , are we going to do it based on this II plan? So we 'll do it on the old plan? Olsen: Correct . i Emmings: And then you 'll show the City 'Council that he 's figured out a way to do it? Olsen: Right . I Emmings: Fine . It 's with the same conditions of approval . I Bill Engelhardt: I think it should be pointed out right up front, the conditions, the 15 conditions that the planning staff's put together and II the engineering staff, we have absolutely no problem with those . What we're talking about is not adjusting lots hudreds of feet or anything like that . The problem came up in this particular area . When we laid this out and you calculate it out, it comes out to 89.58 feet. It didn't meet the J1 90 feet so we had 3 lots that were 89.58 feet wide and we had to adjust th lots down so when we 're talking about lot adjustments, we're talking about tenths of a foot in some cases . We have the same number of lots. They all' meet the requirements. They all meet the 15,000 square feet. It 's just a matter of getting those adjusted to the 90 feet. The other thing that came up is an issue that came up after the fact after we had submitted all the plans and the staff was going to reviewing them, was the Carver County or Southwest Corridor road study. In that road study they're recommending th right-of-way widths for Lyman Blvd. being 120 feet . 60 feet on each side II Planning Commission Meeting October 3 , 1990 - Page 14 of the right-of-way . We have 33 feet on our property which meant we had to dedicate another 27 feet which caused a problem for these lots so we 've taken care of that . We 're going to dedicate the 27 feet along Lyman Blvd . . It also called out wider right-of-way on Lake Riley Road . We 're dedicating the 27 feet on east side of Lake Riley Road and that was after the fact . After everything had been submitted which meant that we use Lot 5 and that will be an outlot and then that will be an unbuildable lot. It doesn't meet the square footage requirements and doesn't meet the width. . . Down on Lyman Blvd . where we had to make the adjustment here , we're still able to maintain two lots which. . . The lot areas again are way over the 15 ,000 . In fact in meeting with the staff it was discussed that maybe Lot 1 could be bigger and Lot 2 . . .instead of having an outlot . Whatever the Planning Commission and the staff would like is fine with us. The Park Commission met and their discussion centered around taking Lots 21 thru 26 . It 's a straight line park . We have now done that which meant that we had to adjust again the lot lines on 20 and 19 in order to conform with the park . . .so we met the park need requirements and again we still met the minimum lot sizes . We 're over lot sizes on 20 and 19 . One of the ' requirements was to show easements and typically those easements are shown on the final plat . There 's a graphic I wanted to use in talking about , all of these easements will be granted on the final plat . The green ones are 1 for sanitary sewer . The yellow ones , excuse me are for sanitary sewer . Green is for storm sewer . The orange ones you see are for access into the ponding area so the City has access to them if they have to do any 1 maintenance . And the blue area shows where the ponding areas or the sedimentation areas are going to be and those easements have been platted • through the wetlands so that you'll have conservation all the way up to the wetlands in those particular properties . We 're not touching the wetlands . 1 We 're not going into the wetlands . We're not going into the fringe vegetation or whatever . We 're staying right on the outside . ' Wildermuth: On the previous map, what land is dedicated for park? The green? Bill Engelhardt: It 's Lots 21 , 22, 23, 24 , 25 and 26. What they wanted, what the Park Commission wanted was a straight line across here or a square in there and so what we did is we cut 21 in half and then we divied the land up , balanced the land between 19 and 20 so again, that was the ' adjustment we're talking about . This is an exhibit of the tree cover on the property . What you see in yellow to the areas that are going to be removed due to the grading. We've gone out and catalogued all the trees . There are some areas that are not going to be disturbed. This area in particular is not going to be disturbed. The major area of disruption for the trees is down around this cul-de-sac area. What we've done to catalogue those , we have 20 elm trees in this grove, 126 box elder , 42 ash and 42 oak . Then down in this area we have 22 elm, 126 box elder and 40 ash. We will be losing a 29 inch oak tree up in this area but the other oaks will be preserved, 4 of them . We're going to be losing box elder and a 4 inch oak in this area , 4 inch cedar and 2 box elders up in the roadway area . This little run of trees in here will be disturbed . . .6 inch apple tree , box elder , ash, 12 inch elm, box elder , box elder and a 16 inch ash . So what we 're proposing to do, we have a total of 126 what we 'll call significant trees and not meaning the box elder are no more significant but of the oak and the ash and the cedar and the apple, 126 trees that are going to. be removed and Mr . Klingelhutz has agreed that he will plant 3 I Planning Commission Meeting October 3 , 1990 - Page 15 i trees on every lot to balance that off . So we're talking about 3 times 73 or 210 . 1 Emmings: And those won't be box elders? Bill Engelhardt: Actually the project needs some trees . This area has no t tree cover and it benefits the developer to have the trees planted. He has his own tree spade and that type of stuff and he can do that so . . . Anothell concern that came up was the TH 212 right-of-way. This is not an easy piece of property to develop . As Jo Ann pointed out , we have TH 212 corridor cutting across the north half . We have a large wetland area that needs to be preserved and we have to work around and in order to get the II grades , there 's a lot of grading on this but actually to minimize the grading on it , the best layout we could come up with is what you see on the street configuration. The concern on the north side was how does the TH 212 corridor tie into the back of these lots . You have to understand that this center line is 400 feet across here so from the center line to the edge is over 200 feet and then you have another oh 100 feet of lot depth so you 're probably talking about a good 300 feet to the highway right-of-way . But what happens is in order to show this to you , as you come through from the east and go west , the highway grade is a little above the subdivision . Then there 's a very deep cut right through the middle an in fact this 15 feet , there 's 15 feet difference of elevation from the center line of the highway to the lot pads straight through the middle, of the property and then you come out of that cut towards the west edge . SO what I 've done is drawn 3 cross sections, AA, BB, and CC understanding tha A is on the eastern edge , B is through the middle and C is through the west . Those cross sections look like this . The question comes up on berming and noise abatement for the residential properties . On the Sectiol AA which is on the east property line we have an elevation , proposed elevation of TH 212 of 904 .3 at the right-of-way line this 897 so you can see that the highway is actually going to be higher than the property is that particular area but then as you move west, you get to about the middl of the property , we have an elevation of the highway at 901 .5 and the elevation at the right-of-way is 915.2 so there's almost 15 feet differencil in elevation . The house is going to be sitting here and the highway 's going to be way down here . As we go to the west, we come into a situation where you have an 898 at the center line of the highway and 902 which means that this property is a little bit higher but not as much as through the middle of the cut . What we propose to do on that is as it affects Lots 11 12, 13, and 14 on the east end and we can very simply berm that . We have plenty of material in this particular project . We'll berm that so we get sound barrier for those 3 lots. Then we get into that deep cut again and we don't need the sound barrier . Then when we get into Lots 1 , 2 , and 3 on this end we 're putting a berm in and we can utilize the tree planting, the operation that we have for some tree plantings and plant trees on top of II that too . I 'd anticipate that that berm in those areas will probably be about 8 feet high but we don't want to get it such that it's not going to be a straight up and down berm. It's going to have to be something that ' gives you rolling slopes that these property owners will be able to work with and have a nice back yard too. So the screening of the highway I think can be accomplished. That was a concern that Paul and Jo Ann had bu until they actually saw what those cross sections were like through this particular piece of property, berming is not as significant as what they had I think first imagined. Again, we have no problems with the 15 11 Planning Commission Meeting October 3, 1990 - Page 16 conditions . The conditions that are in your staff report , they 're not ' significant and I hope you understand that we 're not bringing forward a plat that 's completely reconfigured . It's a matter of adjusting some of these preliminary lot lines in order to meet the letter of the law in this case so we don't have to come and ask you for a variance and that 's not our intent with this particular plat . We 're not asking for any variances on it . We agree to all the conditions that the staff has recommended and ' we're more than willing to work with them and hopefully we'll have a good development for the City of Chanhassen. Erhart: Thanks Bill . Would you just remain up here . Maybe if you 'd sit in the front and save some time . Okay , we 'll open this up to public input at this time . If you 'd come on up . Ray? Ray Lewis: My name is Ray Lewis . I live at 9071 Lake Riley Blvd . and I have some . Erhart : Excuse me . The location of that is on Lake Riley . Can you point it out there? Ray Lewis: Right here . This shows the area around the development . First 1 of all I 'd like to say that in general I 'm in favor of the subdivision . I do have some concerns about some of the effects on the surrounding area that . . . I live approximately one block south of Lyman Blvd . on Lake Riley Blvd . . The concerns I have , first of all the first one is traffic . The traffic from the additional 76 or I guess 75 units is going to add significantly to the traffic that 's already carried by Lyman Blvd . and Lake Riley Blvd . and what I mean by this . Currently Lake Riley Hills is right ' here . The Lake View Hills , excuse me . Those of us that live on the south part of Lake Riley Blvd . south of Lyman Blvd . , the deadend down here for the Sunnyslope people , are forced to go up and use one of two choices for ' egress in this area . Either we can use Lyman Blvd. and go to the west or we can go around Lake Riley and then go the perimeter . Right here is the approximate location of the entrance to .Lake Riley Hills , this half section ' and Lyman Blvd . in this area up here, is actually an undeveloped road that has , it 's narrow . It has a lot of undulations, patches , bumps . It 's not a very well developed road and also Lake Riley Blvd. as it goes around the north part of the lake is also undeveloped. So I have a very big concern ' about the additional traffic flow that this is going to be putting on these undeveloped roads . The second thing is, and it 's somewhat related, is the intersection of TH 101 and Lyman Blvd. . If any of you are familiar with ' that intersection or aware of it, it's a very dangerous intersection . It 's a very sharp turn here. There's very often crops that hide the view and we 're just . . .use that intersection are waiting for a serious accident to happen there . What the subdivision is going to do is place an additional traffic load on that already dangerous intersection. The third thing is the storm water runoff . Now I read through the staff report and I noticed that a provision is made for holding ponds but the thing that concerns me is that there isn't, as the subdivision is very close to the wetlands area and I want to make sure that the ponds are properly designed so that no water runoff is allowed to go into either the wetlands area or into Lake Riley itself. And I guess the last thing I 'd like to bring up is recreational load on Lake Riley. Currently there's already some subdivisions that have outlot lake access . Lake Riley is kind of unique in the area because it is each year receiving considerably additional I Planning Commission Meeting October 3 , 1990 - Page 17 I recreational load from the . . .and from further development around the area . II It 's not a very big lake as far as recreational lakes go . It 's only 290 acres and I 'm very concerned that additional , significant additional recreational load is going to decrease the quality of use for those who access it both from the lakeshore owners and from the landing. So the following recommendations . Lyman Blvd . upgrade plan and schedule should be completed and approved with all assessments being fully disclosed prior to the development of this property . And I think since the main reason for , upgrading Lyman Blvd . will be the development . I think the development itself should bear a substantial part of the cost . Whatever cost is being assessed. The second thing , I think there should be a plan that's scheduled for the improvement of the TH 101/Lyman Blvd. intersection . I II think that 's essential regardless of whether the development goes in . It 's going to become even more critical if the Lake Riley Hills goes in . The third item is that I think the concept of holding ponds is a viable concep but I feel that the details that need to be carefully worked out along wit civil engineering calculations and should be submitted prior to approval . That includes calculations on flow, pond capacity and runoff . Then lastly I think that it 's important that there should be no special lake access priviledges , that is priviledges beyond those that are afforded to normal non-lakeshore residents of the city on an outlot basis to the subdivision . , I know that in talking with Jo Ann I know that that comes on under a separate permit but I feel that it should be coveted in this approval of the subdivision that there be no special . . . Erhart: Is that it Ray? 11 Ray Lewis: Yeah . ' Erhart: Okay . Would you leave that first one up on the screen then? The issues and I 'd ask , Paul could you maybe address those quickly? Krauss: Well actually, Ray could you put your suggestions and we can deal with it a little bit better that way . Erhart: Appreciate your bringing that in in that format Ray. Krauss: As to the question of Lyman Blvd. upgrading, clearly there's a problem on Lyman Blvd. . We recognize it. The County recognizes it and it 's being dealt with in the eastern Carver County Transportation Study which as a result we're taking substantial right-of-way from this project . This project is not the problem or the sole problem or the majority of the ll problem on Lyman Blvd. . The problem on Lyman Blvd. is that traffic is passing east/west through Eden Prairie and Chanhassen and those volumes are expected to grow particular when the Dell Road interchange opens up on TH II 212 . This project is giving up a substantial value in terms of lots that they will not be able to utilize in giving or in the City's taking of the right-of-way . At some point in the future there may well be an area wide assessment to accommodate improvements to this road. We're not certain ho � that project 's going to be done . We're in the process of developing a capital improvements plan to try to program improvements to Lyman but you have to coordinate with two counties and two cities to do that . We want til expedite that as much as possible and clearly this project is part of the problem but it is certainly not the sole problem. Planning Commission Meeting 9 October 3 , 1990 - Page 18 Erhart: Wait a minute here. Dell Road's going to intersect with Riley Lake Blvd . at some point or why is Dell Road an issue? Krauss: Well if you continue east through Eden Prairie ultimately , I believe you 'll be able to approach Dell Road which will have a new , Dell Road will have an interchange on TH 212. Erhart: Okay , but I mean without going down to Pioneer Trail? Krauss: Right . The plan is scheduled for TH 101 . Again , that's a fairly far removed from this project . It is a significant problem . Ray Lewis: Excuse me . Could I just answer number one? In talking with Jo Ann , I did understand that there was what I would call an indefined ' schedule plan to do that . My point here is that what we 're going to be doing with the development is we 're going to be adding 76 or 75 units worth of people turning right and left onto Lake Riley Blvd . in a very short period of time without a definite schedule of when the road 's going to be upgraded and I feel that the two should be tied together . Erhart : Say Ray , what I 'd like to do here is give Paul the floor and let ' him , if you would just take a seat for a second and let him respond to all the issues at once and then if we need to go , if you need to speak some more , we 'll go after that then . Krauss: As far as the TH 101/Lyman Blvd . intersection goes , that entire intersection 's going to be rebuilt with TH 212. Plans call for that construction to begin in 1993 so that 's a program improving that entire ' intersection will be coming out . TH 101 will be realigned and it should remove the problems in that area . Details of the storm water collection system . We do have calculations . Their engineers prepared it . Our ' engineer will be reviewing it . The storm water system there calls for storm water to be discharged into sedimentation basins which would then overflow into the wetlands which will then overflow into Lake Riley so there 's kind of a 3 level system to protect Lake Riley water quality in ' there and that 's all in the project as proposed and as reviewed in the planning report . As to lake access, there is no lake access being proposed from this development . I 'd be concerned that these residents be afforded ' the same rights to pursue lake access as anybody else would as allowed by the ordinance but they are not proposing any outlots as lake access . Ray Lewis: At this time? Krauss: Right . ' Erhart: What do envision where these would get favored treatment over any other resident Ray? ' Ray Lewis: Well for example in the case of Sunny Slope there was a outlot purchased on the shore and the residents. . .were promised lake access and there 's been a long term running dispute as to what that lake access should be . In other words , they have priviledges that other city residents do not have in terms of lake access through that lot . Erhart: Yeah , we 're real familiar with that. I Planning Commission Meeting October 3 , 1990 - Page 19 1 Emmings: Do they have lakeshore here on this property? I Olsen: Right . Emmings: How much do they have? That outlot? ' Olsen: The width on that? Emmings: How much of it is lakeshore? Krauss: That 's something that we need to have clarified . I was talking til the engineer about that tonight . It appears as though the lot located to the east of this site intervenes along the lakeshore but it 's a meander line so it 's kind of tough to say . To actually find out what we need for that southeast corner of that lot to be staked . If it 's in from the lake , , then it has no frontage . Emmings: And it 's not clear from looking at the survey. You should know too , to set your mind at ease somewhat , the beachlot ordinance we have now which wasn 't there I think at the time of that little lot was set aside down there on Lake Riley that 's been such a thorn in everybody 's side , is much more restrictive . They have to have a minimum of 200 feet of lakeshore . They have to have minimum depths and then they can only have one dock with 3 boats . So we 've got a much more restrictive ordinance now" than has ever been there before . Erhart: Okay . Is there any other public comments on the proposed subdivision? , Dennis Baker : My name is Dennis Baker and I live at 9219 Lake Riley Blvd. which is a couple hundred yards from the intersection in question at Lyman " and Lake Riley Blvd. . I 've lived there for 11 years and through that entire 11 years I have been taking segidisk readings for the PCA measuring the water quality of Lake Riley . I 've worked with the U.S. Geological Survey , Metropolitan Council , the Association. A number of groups studyinil the water quality . The water quality of Lake Riley has improved almost very , very little over the course of 11 years in spite of the fact that 11 years ago the sewer project was completed around the lake and we II anticipated a lot more improvement than we got. One reason for that lack of improvement is the U.S. Geological Survey determined that the eutrophication of Lake Riley was 95% caused by runoff. I contend that a holding pond during a heavy rain that will hold the excess water for whatever , even if it's 24-48 hours, is not going to absorb or have enough vegetation to absorb the additional phosphorous, etc. from lawn fertilizer that will come off of 75 15,000 foot lots so I would like to propose to th City Council that they ask the Department of Natural Resources to investigate what the environmental impact is of this project because that particular holding pond is one of only 3 on the lake and I think it can pretty easily be proven that there's precious few wetlands protecting Lake , Riley now . I think that a further study needs to be done in order to • determine , the engineer of the project had I don't think is sufficient to • determine the environmental impact of this 75 unit subdivision. Another comment I 'd like to make is the intersection of TH 101 and Lymah Blvd . is II an extraordinary concern. There's a lot of accidents there already . A lot 11 Planning Commission Meeting October 3 , 1990 - Page 20 of single car accidents . There 's been many cars that didn't make that curve and fortunately did not collide with another car . Right now it's extremely dangerous because of farm crops which happen to be Klingelhutz ' farm crops . Expressing their concern for the safety of the intersection on ' that intersection . The City hasn't done anything about it and I know people have called the City about the danger on that intersection . I mean you have to go , my wife just is scared everytime she comes through that ' intersection because you have to actually accelerate to come from TH 101 going south onto Lyman Blvd. and hope that there 's not a car speeding coming into that intersection from the south because if there is , you 're going to get nailed and the only way you get through it safely is to ' accelerate up that hill and onto Lyman Blvd. I don't think that , we talk about this particular issue and the previous issue , what we 're going to do ultimately relative to traffic on these projects . I know Chanhassen is ' eager to develop and I 'm as eager as everybody else in here to see Chanhassen grow but we 've got to be careful that we don 't outgrow our britches to the point where we make the community dangerous for it 's residents . Thank you . 11 Erhart: Thanks Dennis . Paul , would you respond to that first issue there? ' Krauss: Well the water quality one is one that we 've become increasingly aware of over the last year or two . Lake Riley has a series of problems that aren 't stemming exactly from the lake itself but as water is flushed ' into the lake . One of the problems that the Metro Council Hydrologist , Dick Osgood has identified is that storm water as it passes through Rice Marsh Lake is picking up sediments on the bottom of that lake that were deposited when there used to be a sewage treatment plant there and ' I believe a chicken farm or something like that and everytime it rains , that 's flushed into Lake Riley with some pretty disasterous results . Water quality is a sensitive issue throughout the city and the City Council has been working with staff and the City Council recently adopted a surface water utility program which is designed to deal with water quality issues in the city . To allow us to do planning to understand what exactly the ' problems are and to actually address solutions with capital improvements or treatment or weed harvesting and street sweeping and everything else . And we are also participating with a number of other governments on water quality issues . I 've been asked to serve on a technical advisory committee for the Metro Council that is trying to work with local governments to establish new regulations for runoff . That doesn't specifically deal with this particular subdivision. However , this particular subdivision is using ' the best availble technology that we have at this time . The water is being flushed into sedimentation basins. That's designed to capture the heavier materials . It does not do a very effective job on capturing nutrients . The water will then pass through the wetland. Wetlands do have an ability ' to filter nutrients to a large extent. Then it will pass out through into the lake . Possibly that is not enough but that is the best technology that we have to offer at this time . The reason why we're going through the ' surface water utility district and participating with the other governments as well is that we want to address this to a better extent . We want to address it comprehensively, not just for Lake Riley but for all the other ' water bodies in the city as well . Erhart: Currently you 're adding how many holding ponds? I I Planning Commission Meeting October 3 , 1990 - Page 21 Krauss: There 's two . Erhart: And what percentage of the water currently goes into the current pond off the site would you estimate? Folch: The predicted increase that needed to be retained back was 1 .75 1 acre feet of storage . I should have the calculations here on the existing . Erhart: I guess what I 'm trying to get a feel for , are we taking the holding pond, is the holding pond is going to keep the amount of direct flow into that existing wetland the same as what it is currently? Bill Englehardt: Yes . Yes it will . But the big difference is that beforil it goes into the wetland and before it goes into Lake Riley, you 're going to be polishing it almost like a treatment pond before it gets to Lake II Riley . I just want to point out that we 're sensitive to the issue of the loading on Lake Riley and that 's why we did put the holding ponds in there but your best cleaning agent for the water going into Lake Riley is your , wetlands . Your wetlands pick up most of the phospherous and most of the nutrients . The only thing they don't get is nitrates and it 's very seldom that the wetlands themselves , the vegetation will pull the nitrates out so those will pass through but I think what you have to remember in this I particular subdivision is we 're converting farmland now that is probably more heavily concentrated with nitrates due to farming than a residential subdivision would . Albeit you 're going to have grass in there and they 're going to be fertilizing their lawns but I think it can be shown by studies , that the heaviest loadings that you have is from the farm operation itself . So I think that if you really wanted to get down and look at the loading i this particular thing , you 're probably going to see less nitrate loading which is the most detrimental to Lake Riley than what you 're going to see with the subdivision . • Dennis Baker : Can you tell what percentage of that land is currently in I crops? Bill Engelhardt: I don't know . John, can you? , John Klingelhutz: I think about 60%. Bill Engelhardt: Okay , about 60% of it. So I think we're helping, we 're I going to help the situation. I really don't think we're going to hurt it and we are channeling our storm water runoff into the ponds prior to I entering wetlands . Prior to entering Lake Riley and as Paul said, that 's the best we can do right now. Dennis Baker: Is there any other alternative for drainage? 1 Bill Engelhardt: Not really. On this particular piece of property just the way it is . You have your wetlands with everything coming, the slopes ' all coming down to it . Dennis Baker : It 's a basin . , Bill Engelhardt: Right . It 's a big basin and we're preserving and maintaining easements all around that so those wetlands aren't going to be im 11 Planning Commission Meeting October 3 , 1990 - Page 22 touched. They 're going to stay there in their condition the way they are today . Erhart: Thanks Bill . Any other comments? Dave Nickolay: My name is Dave Nickolay . I live at 8500 Tigua Circle . I 'm curious why we were invited to the meeting when it appears that the development is all to the south of the new Hwy . 212 right-of-way . Krauss: All property owners within 500 feet of the property boundary are notified . The property boundary goes up to Tigua . It's going to be outlot ' correct . Nothing 's being proposed up there but you 're on the notification list because you 're within that 500 foot circle . ' Dave Nickolay: Okay , and I guess then my concern would be originally on the map that was sent, which was a very rough , it showed the property as I think was just shown here a little bit ago by the first gentleman , what is the plan for the land which would be north then of the proposed TH 212? Olsen: There are no plans at this time . They are showing it as R-12 zoning but that would require a rezoning and a lot of ether public hearings ' but at this time it 's an outlot . They 'd have to go through a whole other process . ' Erhart: And R-12 is what Jo Ann? Olsen: High density , apartments . Again , that 's just what they showed on their plan . It 's not even on the official application. Dave Nickolay: Was it in the original because this was a delayed process because I think it was up about a month or so ago and almost all the ' residents from Tigua were here at that meeting and was that a change in the plan? ' Olsen: Oh , no . It was tabled at that time because of the issues that we had on the single family lots but no , there has not been anything proposed throughout this application. Dave Nickolay: Is the land owned by the same people who are developing the land to the north? ' Olsen: It 's all one piece. Dave Nickolay: Okay . Are there plans to do something with the land to the north of that? ' John Klingelhutz: At this time, no. Dave Nickolay: That 's all I have . Thanks. Erhart: Okay, thank you . Another person here? ' Don Sitter : My name is Don Sitter . I live at the end of Lake Riley Blvd . and I 'm going to pretty much echo the same concerns we've heard before but ask a few more questions. Regarding the holding ponds , if those are I Planning Commission Meeting October 3 , 1990 - Page 23 1 capable of handling the runoff now, are there plans or ordinances or any kind of maintenance items that would take care of making sure that they stay in effect or that they are effective both today and 50 or however , 10 years from now so we make sure that the water quality of Lake Riley is maintained? I appreciate that they're at least concerned about the water I quality . I want to make sure it stays that way forever and I guess I 'll finish my other comments and maybe you can get some reaction. With regards to the Lyman Blvd . situation . I hear that we 're admitting that it 's already a problem and the traffic is already too much for that road and thll State and we 're going to further compound the problem and yet there 's no plans in place to rectify the problem . That really bothers me . I don't know why we can't stop somewhere along the line and say before we add morel problems to an already existing problem, that we can take care of it . I agree with the concerns about TH 101 and Lyman but at least you 've got a date . 1993 there will be some resolution . That 's a plan . That 's some I action being taken . I can live with that . Maybe we can do something temporary until 1993 comes along but are there any plans for Lyman Blvd . right now? That 's a pretty bad situation . And the other thing , on the lakeshore access . I 'm very much afraid that they're going to end up with some type of a beachlot or an outlot on there and have 75 homes being accessed to the lake and I understand there's ordinances in place but I also remember a little while ago when Lake Riley Woods was being developed' and the ordinances were just changed because they didn't meet that development . They required the houses to be so close to the beachlot itself and they said , well these houses aren't close enough so let 's just II change the ordinance and I 've seen those ordinances changed through the years and I think you spend a lot of time making the ordinances and if you stick by them , I think we could handle the situation . I 'm afraid that there 's going to be pressure on this one when that actually comes up and ordinances may be changed and then they're going to have another 75 homes with access to Lake Riley and the lake just can't handle anymore. We 're already in trouble as it is . Other than that , I understand the City 's growing and we have to have developments and I guess all and all I don't think it 's a bad development . I think there are some real concerns to make sure that the lake is protected but are we really looking at it for the long run . Thank you . Erhart: Thanks Don. I 'll respond again. As Paul indicated, that City Council here just passed an ordinance to create a utility for maintaining ' holding ponds and wetlands and use for storm water control . Don Sitter : And that includes money for maintaining on an ongoing basis? Erhart: Right . Number two, I think the Lyman Blvd. thing is going to be a big issue and I 'm sure the commissioners will address that here in the II questioning . Three , I guess maybe I can speak for the current Planning Commissioners . I don't think we're, I doubt seriously whether we're going to relax any time soon the requirements for beachlots. As Steve pointed out , it 's pretty severe and this one wouldn't qualify as it is now . ' Ellson: They don't have the 200 feet. Erhart: According to what I see here , there is no shoreline . Jo Ann , do II you have any additional thing to tell? I Planning Commission Meeting October 3 , 1990 - Page 24 I Olsen: We got some half sections that show that it does have shoreline and then the survey here doesn 't really actually show where the ordinary high water mark of Lake Riley is so there'd have to be , but even if it does , it doesn 't meet the square footage . It doesn 't have the lot depth and it would require a lot of variances which I don't think that we would be granting . Don Sitter : . . .variances is a piece of cake in Chanhassen . Erhart: I don 't think that 's true at all . Okay , we can deal again with the beachlot . Go ahead. Come on up. Norm Grant : I 'm Norm Grant . I live at 9021 Lake Riley Blvd . and I 'm just a stone's throw from the project . Two ideas really . One is Lyman Blvd . as I understand it and like you say , it 's going to be a big problem . Land has been dedicated for the widening of that , if I 'm understanding all of this right . but that 's something that 's down the road . A tentative or a preliminary solution, something we could do right now , I was talking with ' Fa:' earlier , was turn lanes . Something like that that would just make that a little bit safer area . If you 've driven Lyman Blvd. you know that it 's bad shape . It 's hilly . It 's in rough shape and I think turn lanes could be a solution at least , a temporary one for when ultimately there 's 11 enough development there that almost demands that something be done . Okay? And by the way , I think that 'd it be wise that that be part of the development plan or the platting of the proposal or however you describe ' that . Another idea I guess is the outlot . I sense that there 's something c-)ing on there that in the future could be trouble for Lake Riley . When I first saw that it appeared that it was a lot and probably a buildable one at that although with variances . Now because of dedication of lands for the widening of Lake Riley Blvd. , it appears that that 's destined to be some kind of an outlot and I guess I feel that in a couple years when there 's 75 families there demanding that they have lake access , their wishes probably will be met one way or another . If I saw the drawings accurately earlier , the widening was done on both sides of Lake Riley Blvd . . 27 feet I think into that outlot . What if the whole distance ' was taken from the other side of the road? Okay, leaving that lot basically intact and then potentially buildable . In my mind's eye , I 'd. rather see a single family home there. Okay? Somebody living there rather than having 75 potential families utilizing that property . Ideas I guess . Erhart: Okay , thanks Norm . Jo Ann, is there any comments on the TH 101 intersection turn lane idea? Olsen: That 's something that could be part of this development and we were just discussing it . That actually is a good idea . Turn lanes on Lyman . ' Krauss: On Lyman and leaving 'the site. Erhart: At the intersection? Olsen: Of the development . Erhart : Norm, that 's what you were talking about is turn lanes at the entrance? I Planning Commission Meeting October 3 , 1990 - Page 25 Norm Grant : Yeah . Erhart: Okay . Any other public comment? Emmings moved, Ahrens seconded to close the public hearing. All voted in I favor and the motion carried. The public hearing was closed. Erhart: Okay , let 's talk this one around a little bit . Joan , do you want to start down on your end? Ahrens: Back to the Lyman/TH 101 intersection. It seems to me , I drive that by there all the time and you can 't see around the corn. That 's the III biggest problem and John Klingelhutz owns the corner lots on there? Olsen: It might be another Klingelhutz . I Ahrens: Oh , someone said that earlier . Can't the City somehow require the lot owners to cut down the corn on those intersections to improve sight lanes based on public safety? I Krauss: We may be able to declare it a public nuisance. That ordinance is not very tight but we could look at that . I AJ-,rens: It wouldn 't cost the City much money I wouldn't think to solve t`,e , temporarily solve the problem until 1993 when the intersection there is completed . Erhart : Excuse me a second . I guess I 'd like to point out , I don't think there 's , let 's clarify that Jo Ann or Paul . When do you realistically see I this TH 101 intersection being put in, or even start construction? Krauss: Well it 's going to be tied to the realignment of TH 101 which is I tied to Hwy . 212 . The State has committed funds to start construction of TH 212 in 1993 . They're not specific on when that gets it out here . It 's probably going to be in 1994 by the time the work comes out this far . , We 've been trying , the City's been trying to expedite that project for years and at least there's finally funding for it. Erhart: I just didn't want to leave the impression with anybody that 19931 work was going to begin at improving those intersection. Go ahead Joan . Ahrens: Maybe cutting the corn down is a more viable solution. As far as the holding ponds go, I 'm going to have to go along with the City recommendation on that . . . .that the holding ponds that are proposed . . . In going through the report, there's a mention of sidewalks here along the north road and west road . I know the City has had problems before in other, developments . Curry Farms for one, stating- that there may be sidewalks there but not putting it onto the plat so the residents after the fact say we don't want sidewalks there . We didn't know about it. I Olsen: Right . I believe what we do now is that 's part of the construction of the street . The sidewalks are installed so whenever anyone purchases all lot , it 's there . Planning Commission Meeting October 3 , 1990 - Page 26 I Ahrens: And install . . .and they will be put in for the north road and west road? Olsen: Yes . Ahrens: I had a question about the utilities . There seemed to be a question about the calculations for the sanitary sewer system to verify site capacity and maybe . . . no idea what 's going on with that . A plan right now because of . . . Folch: Maybe I could just , I 'll briefly address that . That 's just a ' normal requirement that we have as one of the items we want to see for submittal at the time of final approval of construction plan documents . It was not a requirement at this time but we like to make the applicant aware that it is needed for the final stage . Erhart : I think to expand on that . I think there is an issue here with whether the existing sewer has the capacity , whether the existing pump ' station and force feed has the capacity service area . That 's the impression I get . • ' Ahrens: That 's the reason I brought it up is because I think . . . Bill Engelhardt : That was a question that came up . This particular land is served by a lift station and we checked the pumping records and the maintenance records of that lift station . That lift station runs 2 hours a day out of 24 which means that there 's adequate capacity . It 's not running anywhere near what it probably could be running to operate at a normal rate . As far as the 4 inch force main goes , for this particular type of development and number of units that go in there , what happens is that your 4 inch force main will see a little bit more velocity in it if anything . And if your pumps are going to generate , if you 're generating more flow , your pumps are going to be pumping a little bit more and they might pump at a little higher head which means you 're going to see a little bit more velocity but the flow is still going to get through there . It 's a pressure ' situation . It 's not a gravity flow where it 's going to get clogged so it 's going to get pushed through there. The bottom line is that the lift station has capacity for this particular development . It's only running 2 hours a day . Ahrens: Do you agree with that? Bill Engelhardt: That came right from the pumping records of the City . Erhart: Okay , thanks Bill . What is the City's position? ' Folch: Well I guess we'd have to take a closer look at that. That may be an issue that would be addressed in the feasibility report that is proposed to be conducted for servicing watermain and utilities to this subdivision . Bill Engelhardt: That really doesn't answer the question. The feasibility study that 's being proposed is to provide water service and Mr . Klingelhutz has agreed to pay for the feasibility study for the water service . When we get into the final design for the utilities in this particular property , you look at the heads and the design capacity of the pumps . If your pumps , I 1 Planning Commission Meeting October 3, 1990 - Page 27 1 if it appears that your pumps are going to have a problem with capacity , it 's a very simple matter of increasing the horse power or dropping a different pump to increase the horsepower and we would have to do that as part of the approval of the final construction plans for the sewer and water . What I 'm telling you is I don't anticipate that because the lift ' station right now is only running 2 hours out of the day, out of 24 hours which means that there 's plenty of capacity in those pumps and I really don't see it as being a problem . But if it does become a problem during the final design, then we change the pumps over to a different pump . The issue then becomes is the force main big enough with a bigger pump . It 's not that it 's big enough. It 's just that it's going to go through there faster is all . , Ahrens: I understood they . . .be a problem . My question was whether the City thought it was a problem . ' �olch: Well it 's my understanding from the City Engineer that the initial reouest for the study was strictly for the watermain service but that Gary' had mentioned that they also added on the scope of that report was to , include sanitary also specifically related to that lift station . Erhart: That 's the way i read the report . While we 're on the subject , dol any other commissioners have any comments on this particular or concerns about this sewer issue? I guess if you don't mind Joan, it just seems to me , whether it 's 2 hours or 4 hours , I don 't know what 's standard . It jus seems to me that the question that I would have , are we trying to tap into a system that just wasn 't designed to essentially a development like this cr are we tapping into a system essentially was to bandaid a problem we ha out on Lake Riley with sewers? With septic systems . Krauss: If I could , that 's basically one of the questions the feasibility study is designed to answered . That line down Lake Riley was initially 1 installed basically to serve the lakeshore homes but there is a lot of capacity left in it . . . .determine how much capacity there is . This site is within the MUSA line today. They are going to be petitioning the city for improvements . At that point we do the feasibility study which is on line to be done and the city determines the best way of serving this and other properties . The cost to them develop, the developer then decides if the cost benefit is there . You know they can still walk away from a project at that point . The improvements that would be installed , the watell improvements certainly are going to serve a number of other properties beyond the Klingelhutz site . Those properties may be subject to some area assessments or something else where they'd be brought into the process but they 're certainly a wide spread benefit that could potentially be had . But that 's a normal process. They petition. The feasibility study. The City Council acts on the best way of serving it and the developer decides if I they want to do the project. Erhart: Okay , well I guess I 'd sure like to see that that be looked at a little more comprehensive manner than just this item for this particular development . We 're just trying to tap into something that 's already undersized or wasn't intended for this , that it be looked at comprehensively because certainly that whole area around that intersection!' is going to require services . 11 11 Planning Commission Meeting October 3 , 1990 - Page 28 Ahrens : I don 't have anything else . Y 9 ' Erhart : That 's it? Ahrens: Yep . Erhart : Okay. Jim? ' Wildermuth: What is planned for the land west of the current development? Krauss: In terms of the Land Use Plan? Wildermuth: Right . Krauss: The draft Land Use Plan shows single family development immediately ' west of the site . It blends into I think medium density or commercial at the TH 101/212 interchange . 1 Wildermuth: I was wondering why the park group chose Lots 24 , 25 , 26 , 22 , 23 and why they wouldn 't come down to roughly where Block 1 lettering is on the map so that any future development to the west could benefit? Krauss: One of the things this would also be serving is existing and potential development to the east . Ultimately that east/west road labeled north road would be extended in both directions . There 's another high ' density site adjacent to the existing apartment complex and the thinking is that we 'd have this road extended over through there looping back out to Lake Riley Blvd . so they would have access to the park as well . Olsen: There 's also the Bandimere Park to the southwest . That 's going to be a larger community park . ' Wildermuth: That 's the undeveloped? • Olsen: Yeah , to the south of Lyman so they were looking at locating the park more to the east of this subdivision . Wildermuth: As you look to the east, how much of that wetland extends east? Does the wetland fade out? Krauss: No . It does extend to the east. In fact, one of the benefits of this development is that wetland is currently bisected by a driveway that ' was filled . Placed on fill right across the middle of the wetland. As a condition of approval for this project, that driveway is going to be pulled out of there and the wetland can function as a whole unit again and not a bisected water body . Wildermuth: That sounds pretty desireable but if that wetland, a good portion of that wetland lies to the east, it's going to be a long hike down to the parklands . I mean I don't know, this doesn't seem too logical to think that that parkland is going to serve much to the east . But that aside , moving on. Where are these proposed turn lanes Jo Ann that you were just referring to a few moments ago that you thought were a good idea? I Planning Commission Meeting October 3 , 1990 - Page 29 Krauss: What we 'd probably be looking at is something along those lines . Possibly being able to widened it out on this side as well so you can make , a turn in this way and out that way . Wildermuth: Who 'd stand the expense for that? A developer? ' Krauss: Yes . Wildermuth: Is Lyman Blvd. a county road or a city? 1 Olsen: At this point it 's not a city road . The County jurisdiction ends at TH 101 and then it becomes City jurisdiction. Wildermuth: Does the City have any plans for upgrading that? Krat•ss: Not at this point . ' Wildermuth: Everybody that spoke from the area has a concern there about Lyman Blvd . . I Krauss: The way that road improvements that benefit an area or a neighborhood typically occur is the City Council 's petitioned to do a feasibilty study on what the road upgrading might accomplish . We 'd be happy to receive a petition . . .City Council to take action on that . Wildermuth : So it behooves the residents in the area now to petition the I Council? Krauss: Yeah . One of the other issues we deal with too with Carver Count" and they with us , is jurisdiction . This road is carrying a substantial amount of traffic that 's generated from not only Chanhassen but around the area that 's just passing through . It 's projected that it will carry more in the future and we may wish, and we've talked with Carver County about this , to have the jurisdictional problems resolved that may ultimately become a county road. Wildermuth: Okay, so that would be one way for the area residents to address this Lyman Blvd. issue? Other than that , I like the proposed berming for TH 212. That looks like a good solution for the highway noise l pavement problem and it seems like holding ponds on the perimeter of the wetland are the State of the Art answer for storm water at this point . I don 't think there's anything, there isn't anything better on the horizon !' is there? Krauss: Well there's more active programs that a city could undertake and that we would intend on to take with the funding provided by the service water utility. Wildermuth: What would that be? I Krauss: Well it 's a range of things that would be considered from something as simple as making sure the streets are swept frequently , particularly before you have the first flush of organic material in the spring to the possibility of weed harvesting . The wetland capture through the weeds capture the nutrients but in the fall the cattails, which absorb I Planning Commission Meeting October 3, 1990 - Page 30 i some of it but the cattails die off and introduce the nutrients to some U extent back into the system . Weed harvesting is something that 's being done . Wildermuth: These are largely city responsibilities then? ' Krauss: Well these would become city programs and responsibilities in the future . That 's what 's envisioned . Right now nobody's doing it . Right now ' nobody has . Wildermuth: There 's nothing here that we could logically expect from the developer in addition to what he 's outlined? Krauss: No . Right . ' Wildermuth: Okay , I support the staff recommendation . Erhart : Okay , thanks Jim . Annette? 11 Ellson: I like the idea of adding the turn lanes . I like the idea of asking the property owner to cut back the corn . I don 't know that we can ' put that into the thing here but as far as solving these short range problems that people have on these streets . The park is dedicated and I 've often wondered this , doesn't mean it 's necessarily going to be built is that right? It 's just set aside at this point? Olsen: Right . And then there 's a separate fund. In addition to giving parkland they also have to give money and they're trying to work it so that ' ss the homes are built , that a park is there. Ellson: That seems to be a concern and a complaint continually from people in new developments . So that 's what I was just wondering . There's no way ' because it 's us building it , basically the city, that we can put anything in here that says it has to be paid in a year or something like that? I know it 's a continual problem that the parkland is set aside and then nobody has but that was just for my own info. I would go along with the staff 's recommendations . ' Erhart: Thanks Annette . Steve? Emmings: Let 's see . Outlot A in Block 3, Bill mentioned the possibility of connecting that to one of the other lots. I think that should be done so that somebody 's responsible for the maintenance and maybe the east end of it ought to be joined up to one lot and the west end of it should be joined up to another but otherwise we've got a piece of ground sitting there that nobody will be responsible for . So I think you've got to get rid of that outlot and join it up to other properties. As far as Lyman Blvd. goes , I guess I look at that a little bit the way, we have the same exact discussion on another scale with TH 5 all the time . We shouldn't be building all these houses out here because TH 5 can't handle the traffic but it 's sort of like cranking a car . You wind up getting the road because you 've got all the people living out here screaming about the fact that I/ they don 't have decent roads and to some extent I think you're going to wind up with your improvements on Lyman Blvd. faster as a result of projects like this . I don't think it 's good planning but I think that 's 11 I Planning Commission Meeting October 3 , 1990 - Page 31 kind of the way the world works . As far as the beachiot issue is concerned , I 'm confident that the Planning Commission as is presently constituted , will never weakened the beachiot but you know , it won't be th same Planning Commission here in a few months . Maybe who knows and that ordinance has been changed and changed and changed. The last changes we II did I think were good ones and the fact is , if they meet the requirements II of that ordinance they get the beachlot . We can't stop them from having it if they meet the requirements . We've got to treat everybody the same , but " if they don 't , they won't get it from us at least as we 're presently constituted . That should give you at least 5 minutes worth of comfort . Lake Riley is a recreational development lake is it not? Olsen: Exactly . Emmings: And it has a public access? i Olsen: On the Eden Prairie side . Emmings: I always like to tie together approvals and to do that with this'll one I would tie the preliminary plat approval . I 'd add a condition to that it is conditioned upon compliance with all conditions of the wetland alteration permit and similarly add a condition to the wetland alteration II permit . That it 's conditioned upon compliance with all conditions of the preliminary plat approval so those are tied together . Is something going to be recorded against each lot that borders the wetland? Eilse-n: Yes . Emmings: Okay , is that in here already? 1 Clser: I didn 't make it a specific condition but we do do that now . We record it against each lot . , Emmings: That 's a development contract and that doesn't record it against each lot . Something should be recorded against every lot to tell them there are prohibitions or we 're going to wind up with another , which one was it? Olsen: Yeah , with the wetland permit, the permit itself is recorded II against each lot and yeah , we could make that a condition . What happened in Curry Farms, it didn't go to all the adjacent lots. We do that now. Emmings: Should it be on here as a condition or will that automatically 1 happen? Olsen: we automatically do it but you can make it as a condition. I • Emmings: And the reason it didn't happen on Curry Farms was , if it's automatic? I Olsen: Well we 've learned our lesson. We went with only along the Class A wetland . We didn 't go along all the Class 8. Emmings: So should I be comfortable that it's going to happen or should I write it in as a condition? 11 Planning Commission Meeting October 3, 1990 - Page 32 I Olsen: I 've learned my lesson, yes . I think you could be comfortable . Emmings: Otherwise I agree with the conditions in the staff report . Erhart: Okay . A couple questions here. Is it clear in the conditions that we are requiring the berming along the future Interstate 212 that Bill described? ' Olsen: We do in condition number 8 state that noise abatement measures such as earth berming shall be shown on the plan . That they do have to provide something like that . Again, their plans have been. . . tErhart: Okay , do you feel that's strong enough language? Krauss : They will have it resolved before final plat . IErhart : Yeah , I was going to suggest that maybe the way to word it would be to some height above freeway center line at any point . I think Bill ' had mentioned 8 feet . You may want to use that kind of wording or something to but as long as you 're satisfied there , I won't dig into it any longer . We 're saying in the future Lyman Blvd . 's going to be a collector , or is it an arterial? Folch: I believe it 's designated or proposed to be a minor arterial Class 2 I believe . Yeah , that 's correct . ' Erhart : Well I think on Audubon Road where Lake Susan Hills West , 3rd Addition or 10th Addition or whatever it is where we have these houses right on Audubon Road without any berming or screening in the back of those lots , back to the yards , I think we were , somehow we overlooked something there because I 'm just aghasted at driving down there and seeing the backs of these houses essentially which are on a street which is going to be ' major . Emmings: We put a berm in there . ' Erhart: It isn 't there now . ' Emmings: I remember , if we're talking about the same place , there was a berm on that plan . Olsen: By the wetland I believe. 1 Emmings: Between the road and the houses . Olsen: By the wetland? Emmings: Yeah , well` the exit from that division goes out onto there. ' Erhart: We talked about this before and I just , it's hard for me to believe that we approved that the way it's going in and I would ask that the staff review the permit on that subdivision. Have you seen it? Emmings: I feel like I remember it when it was in here. Planning Commission Meeting October 3, 1990 - Page 33 I Erhart: But anyway . Krauss: You point though is well taken Mr . Chairman because there 's probably an analogous situation with having what may become a 4 lane street at some point . Erhart: You 're taking the words right out of my mouth. If you would look , at that , it only affects two lots now the way you 're proposing it . Emmings: Three really . ' Erhart: They 're eliminating, Lot 3 is eliminated . Emmings: Yeah , but then there's. . . Bill Engelhardt: It 'd be three lots . ' Erhart : Oh, oh okay yeah . The one Block 1 so three lots and I think we should Put some kind of a barrier between the road . What would you Propose? A berm? Screening? Okay . The names of the streets bothers me . 1 Are we going to leave them that way? Olsen: Those are just there . , Bill Engelhardt : I hope not . Erhart : Thank you . Loop cul-de-sac . Have we considered, what 's , controlling the elevation of hte wetland currently? What controls the water level? Sill Engelhardt: The DNR has got a high water mark set on that . We 've got it shown on the plan . Erhart: What 's the control structure? Olsen: There 's a culvert . , Erhart: Under TH 101? Olsen: Lyman . Or under Lake Riley . I Erhart: Has anybody considered raising the water level in that? From a lot sellability standpoint , just increasing the water a foot would make that not only a more aesthetically pleasing wetland but it also would improve it's nesting habitat without really taking up additional space or if we could take into special consideration, to use at it 's existing high water level and increase the level of the water in that wetland to improve it . I think it also would improve it 's ability to filter . Bill Engelhardt: Mr . Chairman, my experience always has been that the DNR does not look favorably upon changing those elevations, either by culvert or overland swale or whatever it is . My guess is that they probably aren 't going to let you touch that. They set that elevation , in fact that wetland!' was singled out as being purchased at one time by the DNR and those elevations were set so I don't think there's anything we can do about it . 1 Planning Commission Meeting October 3, 1990 - Page 34 Olsen: And it is a really , I think it does have a pretty good depth right now and it 's a high functioning wetland . 1 Erhart: I guess that's not my experience Bill . My experience is that if there is way to improve wetlands , the DNR has been not only willing to talk about it but will actually fund some of it. Olsen: I don't know that this one needs to be improved . In going out there with the DNR and the Fish and Wildlife Service , it was don 't touch you know . It's fine the way it is . Erhart: So you think that 's a waste of time to pursue that? ' Oiaen: Well we could look into it . I don 't know that it needs that improvement . ' Erhart : Okay . Why is Lot 5, Block 1 or am I reading that wrong? One of the conditions is that Lot 5 , Block 1 is not buildable? Owen: It should be Lot 1 , Block 5 . E-hart : Lot 5 , Block 1 shall be designated as an outlot and unbuildable? Olsen: Yeah , I 've got it . Erhart: Okay , Lot 1 , Block 5 . We are requiring that the developer replace trees over , good trees over 4 inches . Is that an ordinance? Is that in our what , clear cutting ordinance? Is that the ordinance or what is the ordinance that we 're using there? c)lsen: I 'm sorry , what? ' Erhart: We 're requiring the builder to replace all trees with caliper over 4 inches . All good trees over caliper of 4 inches . Olsen: The ordinance does allow for the replacement per caliper inch under the landscaping for tree removal . Erhart: Which ordinance? rOlsen: It 's under the landscaping? I believe it 's in the Zoning Ordinance under the landscaping section . Under tree removal . ' Erhart: In what Section? Olsen: Do you have the pages? It 's 1253, page 1253, Section 1179 . Erhart: In the Zoning or Subdivision Ordinance? ' 0. n: Zoning Ordinance . Page 1253, Section 20-1179. Tree Removal Regulations . Erhart: And does that include, let me see . Planning Commission Meeting October 3, 1990 - Page 35 Olsen: It says that the City may require replacement of removed trees on a caliper inch per caliper inch basis . At a minimum however , replacement trees shall conform to the planting requirements set in the. . . That 's where you have to do exterior landscaping and such and shade trees of 6 inches or more caliper shall be saved unless it can be demonstrated that there is no other feasible way. Erhart: Essentially aren't we talking about replaced trees where he 's putting in the streets and everything? , Olsen: What we usually do, we never go the caliper per caliper inch. I mean you would get 1 ,000 . He was saying if there was 170 trees being II removed but the caliper inches is you know, so what we usually do is work with the DNR forester and go out to the site and determine , you know what is being lost and how it 's best to replace those . We never go caliper per caliper inch replacement but it does give us flexibility to provide • something in the future that will replace what 's been lost . Erhart: Okay . Would we consider on this outlot , Block 5 , Lot 1 , would well consider turning that now unbuildable lot over to the City? Olsen: No , we haven 't considered that . I don't know actually what we would use it for . Erhart: For example down on Bluff Creek for example , and that was subdivided south of the golf course there . A lot of the , all the area in II the bluff land was turned over to the city for future whatever . Olsen: For nature and trails . , Erhart: Nature and whatever . It would seem to me that would give the City control over this lot . Also it would provide maybe some potential future again comprehensive use of what is a long unuseable , I shouldn't say unuseable . Now it 's unuseable shoreline . It could be something . I mean you could put a walking path through there or something . Olsen: It 's real , well . Erhart: Well you 'd be surprised what somebody, at some day when that areal all gets developed, you know you could just like the Lake of the Isles thing where it 's just a walking area . Not a beach but something useable and at this point it becomes an outlot that somebody , John will be paying taxes on it which he probably doesn't want to do if it 's of no economic value to him and this point might be an appropriate time to look at simply II turning it over to the City. So any other comments from the Commissioners on the idea? No? Okay . No positive ideas? Emmings: I don 't think it 's a bad idea . Erhart: You do? I Emmings: I do not think it 's a bad idea . I 'm sitting here looking at that piece of property and thinking he wouldn't have to buy much to the east and add a little something to it to have what he needs to put in a beachlot . The other thing is , maybe the neighbors who don't want to see that happen I I Planning Commission Meeting October 3, 1990 - Page 36 may want to go together and buy it themselves . That 's what occurred to me . Bill Engelhardt: Yeah Mr . Chairman , that 's a valuable piece of property . We don 't want to give it to the City. We'll hang onto it . ' Emmings: As long as we 're talking about it , is there any plans to do anything with that at this time? Bill Engelhardt: Not at all and there is none. There's nothing you can do with it . ' Emmings: Have you considered making it a beachlot? Bill Engelhardt: No . We haven't . You can't do anything with it but it's ' still a valuable piece of property . Mr . Klingelhutz wants to own that piece of property . If the City wants to buy it at it 's market rate , I 'm sure he would sell it to you but we aren't going to give it to you . Emmings: What 's the value Bill? Bill Engelhardt: I don't know. Emmings: No , no . I mean what 's the , how does it have value if he can 't use it for anything? I 'm just curious . Bill Engelhardt: The value is that he wants to own a piece of property on Lake Riley . Don Sitter : Who maintains that? Emmings: The owner . Don Sitter : The owner has . . . Erhart : Okay . I like the sidewalk plan and I agree with, as much as I just stated that I don 't think we give variances liberally , I think this one makes good sense I support the agreement with agreeing the variance . My overall comment on this plan is that I think what we 're doing here is that ' we 're developing this piece of property a little bit in advance of where our services are at the time . Not that doesn't mean that every development , that doesn't mean that developers don't have every right to do ' that but on the other hand, we have some mechanisms that allows them to contribute their share when they do that. I really think that as this gets moved on to Council , that we ought to take a look at two things here in a more comprehensive manner before this gets approved. One is the sewer , and ' I really think we ought to look at a plan for that whole area . The area south of essentially south of Lake Ann Interceptor down to where the end of the proposed addition to the MUSA line is to see what that sewer system l would look like . And I think this developer ought to be made to contribute to that plan at this time . Secondly, I think the City should proceed with the feasibility study for Lyman Blvd. . I think the one shocking thing on ' this whole development is that we 're going to put , not only are we going of put 75 additional households on a street that simply is not designed to do that . Not adequate to do that , but we 're going to put essentially for up to 10 years , perhaps even longer than 10 years, a cul-de-sac . If you I Planning Commission Meeting October 3, 1990 - Page 37 measure it from Lyman Blvd. to the east end of North Road, how long is it? 2 ,000-3 ,000 feet? I Olsen: Close to it . Erhart: 2,000 feet? I 've been here 4 years and anything over 1 ,000 feet I is , we've used that as a reason to force developers to come up with alternative access. And I 'm not against this plan. I think it 's a good plan . I think they 're using the land wisely . I think they've addressed I the runoff issues to the best, say to the same level as other developers are doing . I don't think that we should, I think now is the time to go in and collect monies to improve Lyman Blvd. . I really think it should be tied together because it's not reasonable to put this house on there on Lyman Blvd. in it 's current condition I don't think . Wildermuth: But the adjacent property owners petitioned the Council to do II that , then that will be addressed? If they don't petition the Council to do that , it won 't be addressed . Erhart: The City can proceed with this on their own . It doesn't require all Petition . Correct me if I 'm wrong . It doesn't require a petition of anybody . ' Olsen: The City can initiate it . Erhart: Yeah , we can initiate the feasibility study . ' Krauss: Yeah , the City can but you know the City likes to know that a neighborhood honestly wants a road to be improved before we go to the expense of figuring out how it 's done . Wildermuth: You have all the adjacent property owners . Erhart: But the neighborhood is the developer today. Krauss: I think it would not be unreasonable to ask the developer to commission the City to undertake that feasibility study in conjunction with the neighbors signing onto that but there are many instances where we hear that , and obviously we agree that there's a road improvement needed at some' point and we do agree with that here but when the plans are actually developed for the road improvement, the neighborhood turns out and says that we don 't want this and you know . It puts the city staff in an uncomfortable position of taking the lead on a project that 's to benefit for a neighborhood . We'd like to know that at least the neighborhood 's behind us looking into that improvement. Erhart: There is no neighborhood . The developer is the neighborhood and I he has access to the funds today . Wildermuth: The neighbors that we've heard from tonight . One of the things that we see, the more expense we tack on to a development like this for the developer , I think the lower quality, the lower caliber development w get in the end . If you look around town and look at the costs of land II and costs of some of these developments, I think we 're diluting the developer 's efforts by tagging him with a lot of additional expense . I • Planning Commission Meeting October 3 , 1990 - Page 38 Erhart: Yeah , I understand that but some day someone's going to pay for Lyman Blvd . improvement . Either you 're going to go in . Wildermuth: That 's right. The property owners are going to pay for it . Adjacent property owners . Erhart: And the thing is that that serves 75 lots here and if you let this go in without doing that today , then you 're never going to be able to ' collect from 75 lots . You 're going to go at . emmings: Why not? ' Erhart: Well you could but I 'm just saying it's easier to . Elison: That 's how . . .you have 75 more people who want it and hopefully we ' ll be . . . Erhart: Are you? Ellson: Your comment before was the 75 will be more clout to get it . 11 Ray Lewis: How many people want it now? Erhart: Well that 's not the issue . I 'm just trying to get some things in the Minutes here Ray and we 're not going to decide that here . So anyway , those are my comments . Is there any other discussion? Emmings: Yeah . I have one other question . Bill , I think last time , didn 't you engineer Timberwood? Didn't you present Timberwood to us? Bill Engelhardt: Timberwood Estates , yes . ' Emmings: I 'm just wondering if you 're going to come and help us when we have to face all those folks in the hearings on the Comprehensive Plan . Bill Engelhardt: As far as sewer goes? Emmings: No . ' Ellson: Development around it. ' Emmings: A whole bunch of other issues. I think that was the last time I saw you was on Timberwood and it kind of scares me when I see you now for some reason . ' Bill Engelhardt: At that time there were no plans for anything around there . ' Erhart: Okay , if there aren 't any more comments , I 'll entertain a motion . Emmings: I 'm going to move that the Planning Commission recommend approval I . of Preliminary Plat #90-10 for Lake Riley Hills as shown on the plans dated September 4 , 1990 with a variance to permit a 240 foot offset between the intersection of South Road and Lyman Boulevard with the conditions as set forth in the staff report changing to 15 so that we 've got Lot 1 , Block 5 . 1 Planning Commission Meeting October 3, 1990 - Page 39 Adding 16 which will state that approval is conditioned upon compliance with all conditions of the Wetland Alteration Permit . Adding a 17th condition that says that the applicant should look into the feasibility of !' turn lanes and turn lanes should be added if the City staff feels that it 's appropriate and necessary for safety to get people in and out of that new subdivision . Adding an 18th condition that would say that Outlot A in Block 3 shall be under ownership of adjoining properties in some manner . However the developer wants to divide it up. Adding a 19th condition that plans shall be drawn and submitted to the staff for approval to get a berm , and screening along Lyman Boulevard and between Block 1 , Lot 1 and Lots 1 and 2 in Block 3 . Erhart: Is there a second? , Wildermuth: Second . Erhart : Any discussion? Emmings moved, Wildermuth seconded that the Planning Commission recommend I approval of Preliminary Plat #90-10 for Lake Riley Hills as shown on the plans dated September 4, 1990 with a variance to permit a 240 foot offset between the intersection of South Road and Lyman Boulevard with the following conditions: 1 .

I Erhart: i oppose it on the basis that I don't believe that even though I like the plan , I don 't believe that we've done adequate assurances that II Services , both the transportation and sewer are adequate to see this as a positive development . Emmings: I 'd like to ask a question to follow up on what he just said . We 're doing a preliminary plat here . Before this is a done deal you 've got a feasibility study to do and you've got to do, there has to be final plat a?oroval also by the City Council and now if deficiencies were found in the' feasibility study . Krauss: They would be addressed prior to final plat approval . 1 Emmings: See there 's another plat of this . Just want to be sure . Erhart: Okay , now we have to deal with the wetland alteration permit . Is there any discussion on that from the Planning Commission members? If not . would someone make a motion to deal with the wetland alteration? Wildermuth: I 'll move that the Planning Commission recommend approval of II the Wetland Alteration Permit for Lake Riley Hills Subdivision as shown on plans dated September 4 , 1990 with the following conditions 1 thru 3 and adding condition 4 . Steve , what were those words? Emmings: It would just be conditioned upon compliance with all conditions of the preliminary plat approval . i Wildermuth: Those words . 4 Planning Commission Meeting 11 October 3, 1990 - Page 42 Erhart: Okay, is there a second?

PUBLIC HEARING: SITE PLAN AMENDMENT FOR A 4.260 SQUARE FOOT ADDITION TO THE EXISTING BUILDING ON PROPERTY ZONED IOP AND LOCATED AT 7870 PARK DRIVE . INDUSTRIAL INFORMATION CONTROLS. Sharmin Al-Jaff presented the staff report on this item . Vice Chairman Erhart called the public hearing to order . Erhart: Is the developer here, the building owner? Okay , do you have all the conditions? Have you seen all the conditions? Tom Ryan: Can I speak to a couple of them? Erhart: Alright . Go ahead . Tom Ryan: My name is Tom Ryan and I represent R.J . Ryan Construction, the ' general contractor for the building. There 's two issues that we 'd like to , a couple issues we'd like to address. The first regards the drainage problem which exists with the neighbor to the north . We feel it 's important that we go on record as stating that Industrial Information ' Controls and R .J . Ryan Construction did not cause the drainage problem which exists . The drainage problem which exists is a result of the failure of the previous engineering staff of the City of Chanhassen as well as the ' contractor for the Component Engineering building which allowed the water to run up against our property . In the interest of solving the problem we agreed with Component Engineering and the City staff that 's presently in place that because we have a lot of excess material , we would provide the I 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1
