3. Kenyon Bluff SubdivisionCITY OF CHANHASSEN PC DATE: March 16, 2004 CC DATE: April 12, 2004 REVIEW DEADLINE: May 14, 2004 CASE #: 03-22 SUB/Planning Case 04-03 BY: A1-Jaff STAFF REPORT Z PROPOSAL: Preliminary Plat to Subdivide a 2.16 Acre Lot into Three (3) Single-Family Lots with a Variance, Kenyon Bluff LOCATION: Lots 1 and 2, Pleasant View. Northwest of Pleasant View Road. APPLICANT: CBR Development. LLC Tom Rollings 4550 Weston Lane N. Plymouth, MN 53446 (612) 770-8885 PRESENT ZONING: RSF, Single Family Residential District 2020 LAND USE PLAN: Residential Low Density (Net Density 1.2 - 4.0 units per acre) ACREAGE: 2.16 acres DENSITY: 1.38 Units per Acre Gross 1.8 Units per Acre Net SUMMARY OF REQUEST: Subdivision of 2.16 acres into 3 single-family lots, vacation of a portion of Oak Grove Avenue and a variance to allow a private street to serve the development. Notice of this public hearing has been mailed to all property owners within 500 feet. Staff is recommending approval of the request. LEVEL OF CITY DISCRETION IN DECISION-MAKING: The City's discretion in approving or denying a preliminary plat is limited to whether or not the proposed plat meets the standards outlined in the Subdivision Regulations and Zoning Ordinance. If it meets these standards, the City must approve the preliminary plat. This is a quasi-judicial decision. The City's discretion in approving or denying a variance is limited to whether or not the proposed project meets the standards in the Zoning Ordinance for a variance. The City has a relatively high level of discretion with a variance because the applicant is seeking a deviation from established standards. This is a quasi-judicial decision. Location Map 400 Pleasant View Road City of Chanhassen Planning Case No. 04-03 Pleasant View Road 400 Pleasant View Road Lotus Lake N Kenyon Bluff-Planning Case No. 04-03 March 16, 2004 Page 2 PROPOSAL/SUMMARY The applicant is proposing to subdivide 2.16 acres into 3 single family lots. The property is zoned RSF, Single Family Residential District. The site contains a single family home which is proposed to be demolished. Access to the site is gained via an existing driveway off of Pleasant View Road. Lores Lake An abandoned right-of-way is located northeast of the subject site. The applicant is requesting vacation of the right-of-way. Staff is recommending approval of the vacation with the condition that a drainage and utility easement be maintained over the vacated portion (the vacation of the right-of-way requires City Council action only). Approval of the subdivision will be contingent upon approval of the vacation. The variance in this application is to allow a private street to serve this development. The subdivision ordinance requires a variance be granted in order to allow a private street. Staff is recommending approval of the variance to minimize grading and for safety reasons. This issue is discussed in detail later in the report. Staff has been working with the applicant for several months. Several development scenarios were examined including a four-lot subdivision. Staff directed the applicant to show how the site would develop if a public street was constructed. Sheet 1 of 1 (Preliminary Grading/Public Road Concept) shows the site served via a public street. This concept mass grades the site, removes most of the vegetation and utilizes retaining walls. Kenyon BlufJ:Planning Case No. 04-03 March 16, 2004 Page 3 The average lot size is 27,860 square feet with a resulting gross density of 1.38 units per acre and net density of 1.8 units per acre. The site is located northwest of Pleasant View Road. All three lots meet the minimum area, width, and depth requirements of the Zoning Ordinance. The site contains a bluff along the southwest comer. The required setbacks will be maintained from the edge of the bluff. The site has mature trees which the applicant is making an effort to preserve. In reviewing this plat, staff worked with the applicant to acquire additional right-of-way for Pleasant View Road. The current right-of-way is deficient in width. In summary, staff believes that the proposed subdivision is well designed. Minor revisions will be required. We are recommending that it be approved with a variance to allow a private street with conditions outlined in the staff report. PRELIMINARY PLAT The applicant is proposing to subdivide a 2.16 acre site into 3 single-family lots. The gross density of the site is 1.38 units per acre and net density is 1.8 units per acre. All three lots exceed the minimum 15,000 square feet of area, with an average lot size of 27,860 square feet. All three proposed lots meet the minimum width, and depth requirements of the Zoning Ordinance. A bluff occupies the southwest portion of proposed Lot 1. The ordinance requires all structures to maintain a 30-foot setback from the top of the bluff. The plans indicate that this setback can be accommodated and no grading is proposed within that area. Staff notes that the proposal is consistent with the Comprehensive Plan and generally consistent with the Zoning Ordinance. WETLANDS There are no wetlands on this site. Erosion and Sediment Control Inlet control is needed following installation of inlet structures. Inlet control methods will be varied before and after pavement of the street. Before pavement, inlet protection could consist of heavy-duty mono-mono silt fence with 4-foot spacing of metal T-posts and 1" rock around silt fence material. After pavement, compost socks, sand bags or rock and wire could be used as temporary inlet control. Silt fence should be provided as needed to prevent sediment from leaving the site. Erosion control blanket should be installed on all slopes greater than or equal to 3:1. All exposed soil areas must have temporary erosion protection or permanent cover for the exposed soil areas year round, according to the following table of slopes and time frames: Kenyon Bluff-Planning Case No. 04-03 March 16, 2004 Page 4 Type of Slope Time Steeper than 3:1 7 days 10:1 to 3:1 14 days Flatter than 10:1 21 days (Maximum time an area can remain open when the area is not actively being worked.) These areas include any exposed soil areas with a positive slope to a storm water conveyance system, such as a curb and gutter system, storm sewer inlet, temporary or permanent drainage ditch or other natural or man made systems that discharge to a surface water. Street cleaning of soil tracked onto public streets should include daily street scraping and street sweeping as-needed. Surface Water Management Fees Water Quality Fees Because of the impervious surface associated with this development, the water quality fees for this proposed development are based on residential single family development rates of $1,028/acre. Based on the proposed developed area of approximately 1.92 acres, the water quality fees associated with this project are $1,974. Water Quantity Fees The SWMP has established a connection charge for the different land uses based on an average citywide rate for the installation of water quantity systems. This cost includes land acquisition, proposed SWMP culverts, open channels, and storm water ponding areas for runoff storage. Residential single family developments have a connection charge of $2,545 per developable acre. This results in a water quantity fee of approximately $4,886 for the proposed development. SWMP Credits This project does not propose the construction of NURP ponds and is therefore not eligible for SWMP credits. At this time, the estimated total SWMP fee, due payable to the City at the time of final plat recording, is $6,860. Other Agencies The applicant shall apply for and obtain permits from the appropriate regulatory agencies (e.g., Riley-Purgatory-Bluff Creek Watershed District, Minnesota Pollution Control Agency, Minnesota Department of Natural Resources (for dewatering)) and comply with their conditions of approval. GRADING, DRAINAGE & EROSION CONTROL The existing site has tree cover over approximately one acre of area. The existing bluff limit line follows the entire west side of proposed Lot 1 and the private street. The plans propose to grade about 50-60% of the site for the new house pads and private street. The proposed grading will prepare the site for full basement and walk-out house pads. Drainage swales have been proposed Kenyon Bluff-Planning Case No. 04-03 March 16, 2004 Page .5 along the sides of the houses to maintain the neighborhood drainage pattern through the properly. The plan proposes a retaining wall for tree protection on Lot 1. The applicant should be aware that any retaining wall over 4 feet in height must be designed by a Structural Engineer registered in the State of Minnesota. Also, it will require a building permit from the Building Department. Staff is concerned with the proposed grading in the rear yard areas of Lots 1 and 2. There is a steep slope (3:1) in the rear yard of Lot 1 which drains toward the house pad. Staff has concerns about the ability of stormwater to safely drain around the house pad at the elevations shown. Staff would recommend that either the house pad be raised one foot in elevation or that a small, 2 to 3-foot retaining wall be installed to better facilitate drainage away from the house. Also, the proposed rear yard of Lot 2 is a steep, vertical drop of over 20 feet from the house pad to Pleasant View Road. In order to provide a usable rear yard area, staff would recommend that a flatter, 10:1 slope be used for the first 15 feet off the rear house pad along with a 4-foot retaining wall. The existing site drainage is encompassed within two different drainage areas. The site drains off site to the east and west directions toward Pleasant View Road. Under developed conditions, the applicant is proposing to capture all of the rear yard drainage from Lot 1, all of the street drainage and all of the front yard drainage from the tots. This stormwater will be conveyed via storm sewer to an existing pond at the comer of Horseshoe Lane. The proposed storm sewer must be designed for a 10-year, 24-hour storm event. To better treat the stormwater, the applicant is proposing a stormceptor manhole to provide additional water quality treatment of the stormwater. Tree preservation fencing must be installed at the limits of tree removal. All disturbed areas, as a result of construction, shall be seeded and mulched or sodded immediately after grading to minimize erosion. A 75-foot minimum rock construction entrance must be added to the entrance that will be accessed during construction. If importing or exporting material for development of the site is necessary, the applicant will be required to supply the City with a detailed haul route and traffic control plan. UTILITIES The plans propose on extending sewer and water from Pleasant View Road on the east side of the parcel. Overall, the utility layout looks fine. Upon completion of the utility improvements, the utilities will be turned over to the City of Chanhassen for maintenance and ownership. According to the City's Finance Department records, the parcel was previously assessed for one sanitary sewer and water hookup. Since the developer will be responsible for extending lateral sewer and water service to the lots, the sanitary sewer and water connection charges will be waived. However, the sanitary sewer and water hookup charges will still be applicable for each of the new lots. The 2004 trunk hookup charge is $1,458 for sanitary sewer and $2,814 for water-main. Sanitary sewer and water-main hookup fees may be specially assessed against the parcel at the time of building permit issuance. All of these charges are based on the number of SAC units assigned by the Met Council. Kenyon Bluff-Planning Case No. 04-03 March 16, 2004 Page 6 Public utility improvements are required to be constructed in accordance with the City's latest edition of Standard Specifications and Detail Plates. Detailed construction plans and specifications must be submitted at time of final plat for review. The applicant is also required to enter into a development contract with the City and supply the necessary financial security in the form of a letter of credit or cash escrow to guarantee installation of the improvements and the conditions of final plat approval. Permits from the appropriate regulatory agencies will have to be obtained, including but not limited to the MPCA, Department of Health, MCES, and Watershed District. STREETS The plans propose accessing the lots via a private street from the south side of the parcel off of Pleasant View Road. The applicant is proposing a 30-foot private street easement with a 20-foot pavement width. The plans propose a 10% slope private street with a half hammerhead turnaround. The proposed hammerhead turnaround configuration has been reviewed and approved by the City's Fire Marshal. In addition, the private street must be built to a 7-ton design. The developer will be required to submit inspection reports certifying this. Also, the existing driveway to the site off of Pleasant View Road must be removed. Pleasant View Road is designated as a collector road in the City's Comprehensive Plan. Current city code requires that collectors have a right-of-way width of 80 feet or 40 feet from the right- of-way centerline. Due to the existing environmental features (bluff's, trees, Lotus Lake) around Pleasant View Road and the tight space constraints of the area, it is unlikely that Pleasant View Road will ever be upgraded to the full width of current City standards for collector roads. As such, staff does not feel that a full 40 feet of right-of-way from the centerline of Pleasant View Road is needed with this development. In keeping with the dedicated right-of-way width for Pleasant view Road of previous plats to the east of this site, staff has recommended that the applicant dedicate the necessary right-of-way to obtain a 33-foot width from the centerline of Pleasant View Road for a total width of 66 feet. The applicant has shown this on the plans. VACATION OF RIGHT-OF-WAY The applicant is requesting to vacate a portion of Oak Grove Avenue. Currently, no street exists in that area. The grades in the area are steep making a street connection unlikely. Staff is recommending approval of the vacation since the right-of-way is not needed. The City will retain a drainage and utility easement over the sanitary sewer line. Ax/ Kenyon Bluff-Planning Case No. 04-03 March 16, 2004 Page 7 PARK DEDICATION Kenyon Bluff lies within the park service area of North Lotus Lake Park. Future residents of this subdivision will easily be able to access the park via Pleasant View Road. No sidewalks or trails are currently available along Pleasant View Road. It is unlikely that these amenities will be constructed in the future even though a pedestrian route along Pleasant View Road is identified in the Comprehensive Plan. The topography of the area and curvilinear nature of the road would present nearly insurmountable challenges to the construction of a trail or sidewalk. However, if an effort to construct a sidewalk along Pleasant View Road was ever undertaken, the 18 feet of additional right-of-way being acquired as a part of this subdivision could accommodate the improvements required of such a project. It is recommended that the applicant pay park fees in lieu of land dedication or trail construction on two of the three lots. One lot is exempt from these charges due to the existing single family home on the property. The park fee on two single-family homes totals $5,600 and is payable at the time of platting. TREE PRESERVATION/LANDSCAPING The tree calculations shown on the plans have been revised by the applicant (see memorandum dated March 5, 2004 from Schoell and Madson, Inc.). Tree Preservation Tree canopy coverage and preservation calculations for the Kenyon Bluff development were submitted by the applicant and are as follows: Total upland area (including outlots) Baseline canopy coverage Minimum canopy coverage required Proposed tree preservation 93,932 SF or 2.16 ac. 62% or 58,316 SF 46% or 43,208 SF 31% or 28,702 SF The developer does not meet minimum canopy coverage allowed, therefore the difference is multiplied by 1.2 to calculate the required replacement plantings. Difference in canopy coverage Multiplier Total replacement Total number of trees to be planted 14,506 SF 1.2 17,407 SF 16 trees A replacement planting plan must be submitted to the city for approval. Included in the plan shall be location, species and size of replacements. All replacements must meet minimum size requirements. Kenyon Blqlf-Planning Case No. 04-03 March 16, 2004 Page 8 Bufferyard plantings are required along Pleasantview Road. Requirements are as follows: Location Required Proposed Lot 3 - bufferyard B - 2 overstory trees 0 overstory 25' width 4 understory trees 0 understory 215' length 9 shrubs 0 shrubs Existing vegetation and grade changes are sufficient buffers for lots 1 and 2 along Pleasantview Road.

SUBDIVISION - FINDINGS The proposed subdivision is consistent with the zoning ordinance; Finding: The subdivision meets all the requirements of the RSF, Residential Single Family District and the zoning ordinance if the private street variance is approved. The proposed subdivision is consistent with all applicable city, county and regional plans including but not limited to the city's comprehensive plan; Finding: The proposed subdivision is consistent with the comprehensive plan and subdivision ordinance. The physical characteristics of the site, including but not limited to topography, soils, vegetation, susceptibility to erosion and siltation, susceptibility to flooding, and storm water drainage are suitable for the proposed development; Kenyon Bluf/'-Planning Case No. 04-03 March 16, 2004 Page 9 Finding: The proposed site is suitable for development subject to the conditions specified in this report The proposed subdivision makes adequate provision for water supply, storm drainage, sewage disposal, streets, erosion control and all other improvements required by this chapter; Finding: The proposed subdivision is served by adequate urban infrastructure. 5. The proposed subdivision will not cause environmental damage; Finding: The proposed subdivision will not cause significant environmental damage subject to conditions of approval. The proposed subdivision contains adequate open areas to accommodate house pads. 6. The proposed subdivision will not conflict with easements of record. Finding: The proposed subdivision will not conflict with existing easements, but rather will expand and provide all necessary easements. The proposed subdivision is not premature. A subdivision is premature if any of the following exists: Lack of adequate storm water drainage. Lack of adequate roads. Lack of adequate sanitary sewer systems. Lack of adequate off-site public improvements or support systems. Finding: The proposed subdivision will have access to public utilities and streets. VARIANCE FINDINGS VARIANCE Section 18-57. Streets. (r) Private streets serving up to four (4) lots may be permitted in the A2, RR, RSF and R4 if the criteria in variance section 18-22 are met and upon consideration of the following: (1) The prevailing development pattern makes it unfeasible or inappropriate to construct a public street. In making this determination, the city may consider the location of existing property lines and homes, local or geographic conditions and the existence of wetlands. (2) After reviewing the surrounding area, it is concluded that an extension of the public street system is not required to serve other parcels in the area, improve access, or to provide a street system consistent with the comprehensive plan. Kenyon Bluff-Planning Case No. 04-03 March 16, 2004 Page 10 (3) The use of a private street will permit enhanced protection of the city's natural resources, including wetlands and protected areas. Staff reviewed the two possible plat layouts for the site and considered individual driveways off of Pleasant View Road. Staff believes that the best option from a safety and environmental standpoint is the private street option. The option of all the lots accessing directly from Pleasant View Road with three separate driveways is not recommended from a safety standpoint. Each of the separate accesses creates a potential conflict point with traffic on Pleasant View Road, a collector street. The second option of a public street and cul-de-sac serving the parcel requires severe grading of the site. The plans show retaining walls around the perimeter of the site from 2 to 28 feet in height for this option. The final option of a private street serving three lots is the most environmentally friendly with minimal retaining walls and yet does not add any additional access points to the site off of Pleasant View Road. Staff is recommending approval of the private street. VARIANCE FINDINGS Sec. 18-22. Variances. The city council may grant a variance from the regulations contained in this chapter as part of the plat approval process following a finding that all of the following conditions exist: VARIANCE FINDINGS WITHIN SUBDIVISONS The city may grant a variance from the regulations of the subdivision ordinance as part of the plat approval process following a finding that all of the following conditions exist: 1) The hardship is not a mere inconvenience. Finding: The hardship is not a mere inconvenience. The proposed private street preserves significant site features. 2) The hardship is caused by the particular physical surroundings, shape or typographical conditions of the land. Finding: The hardship is caused by the particular physical surroundings, shape and topographical conditions of the land. 3) The conditions upon which the request is based are unique and not generally applicable to other property. Finding: The conditions upon which the request is based are unique and not generally applicable to other properties due to the unique site features. The granting of the variance will not be substantially detrimental to the public welfare and is in accord with the purpose and intent of this chapter, the zoning ordinance and Kenyon Blu~:Planning Case No. 04-03 March 16, 2004 Page 11 comprehensive plan. Finding: The granting of a variance will not be substantially detrimental to the public welfare and is in accord with the purpose and intent of this chapter, the zoning ordinance, and comprehensive plan. The applicant is proposing to access the site via a private street. This option will minimize grading and tree removal as well as provide less potential conflict with vehicles on Pleasant View Road. The applicant's request is reasonable. Staff is recommending approval of this request. RECOMMENDATION Staff recommends the Planning Commission adopt the following motions: VACATION OF RIGHT-OF-WAY (City Council motion only). "The City Council approves the partial vacation of Oak Grove Avenue as shown on plans dated received February 26, 2004, with the following conditions: 1.

February 19, 2004 Sharmeen Al-Jaff City of Chanhassen 7700 Market Boulevard Chanhassen, MN 55317 Dear Sharmeen: This letter is to grant the City of Chanhassen the additional 60 day requirement (until May, 29, 2004) to process my subdivision application (site located at 400 Pleasant View Road). It is my understanding that the application will be appearing before the Planning Commission on March 16, 2004 and before the City Council on April 12, 2004. Sincerely, Tom Rolling PROJECT NARRATIVE FOil KENYON BLUFF 400 PLEASANT VIEW ROAD CHANHASSEN MINNESOTA CITy OF CHANHASSEN RECEIVED FEB 2 6 20O4 CHANHASSEN PLANNING OEP? Project Description: Tom Rollings is requesting the development of three single-family residential lots with a private road at 400 Pleasant View Road. The development is consistent with the surrounding single- family neighborhoods. The 2.1-acre site currently contains a single-family resident, located near the center of the site, with two accessory structures located to the north of the home. The existing home and out buildings will be removed as part of this project. The property abuts Pleasant View Road along the southern and eastern edge. Oak Grove Avenue, an undeveloped platted right-of-way, borders the north property line. Access to the present home is from the southeast comer of the lot. The topography of the site slopes down from north to south with a high elevation of 983 feet in the northeast to a low elevation around 940 feet in both the southwest and northeast comers. There is a bluff in the southwest comer of the site. Project Data: Zoning Standards The property and surrounding lands are zoned Residential Single Family (RSF) and guided for low density residential. The proposed lots will meet all of the required setbacks and zoning standards for the RSF zone with a private street. The proposed lots will exceed the minimum lot size of 15,000 square feet with sizes ranging from 18,471 square feet to 43,213 square feet. The buildable area within each of the lots exceeds the space necessary for a 60 X 60 foot building pad. The subdivision plan includes building footprints of 80 X 45 feet. This size more accurately demonstrates the building pad anticipated for the site. Private Road A private road will access the three lots. The road will enter the site west of the current driveway. This location aligns with the western access of Horseshoe Curve and provides 150 feet of sight distance from the driveway and the curve in Pleasant View Road. The drive will be constructed per city standards with a grade no greater than 10% and a paved width of 20 feet. A hammerhead turn-around will be constructed at the north end of the drive for emergency vehicle access. The drive will be within a 30-foot easement and will be privately maintained. Tree Canopy There are 145 trees on the site. The trees are generally located along the perimeter of the property with heavier groupings within the southwestern bluff area and the northwest and northeast comers. Few trees exist in the central area of the site where most of the development will occur. The proposed development will require the removal of 42 trees. This is less than half of the trees to be removed ifa public road was required. The development will meet the tree canopy requirements of the zoning ordinance. Tree Canopy Currently Tree Canopy to Remain Tree Canopy Required by Ordinance 40,952 sq. ft. (45% of site) 29,090 sq. ft. (71% of existing canopy) 14,333 sq. ft. (35% of existing canopy) Bh~f The bluff in the southwest comer contains approximately 12,780 square feet of area. The subdivision provides the required 20-foot bluff impact zone and 30-foot setback. The bluff will be preserved and protected as part of the subdivision. Previous plans had noted a possible bluff in the northeast comer of the site. This was based on ariel topography that did not show the existing neighboring driveway and retention wall. After resurveying and field verifying the grades in this area it was discovered that the current slopes do not constitute a city defined bluff. Grading Site grading will be required for the construction of the private drive and the building pads. Due to the natural topography of the site minimal grading would be required for the construction of the walkout style homes. This preserves the existing terrain along the eastern side of the site. Although the private drive will require cuts up to 10 feet there is minimal impact to the site. The use of retaining walls is not proposed except for tree preservation. Project Requests Approval of a three-lot subdivision with a private road. Approval of a variance for a private road. Vacation of Oak Grove Avenue. Variance A variance is requested for the construction of a private drive as a shared access for the three lots. A private road is better suited for the development than a public road. To create the preferred sight distances and building locations a public road would need to be placed along the northern edge of the site. This is in an area that contains a nicely wooded slope. To grade a public road through this area would not only destroy the natural amenities that the development is trying to preserve, but it would negatively impact the character of the neighboring lots. This is demonstrated by the attached concept plan showing how the development of the site with a public road. The issues with a public road are: · At a 7% grade, the road will require cuts in the existing slopes up to 30 feet. · The required cuts will require the construction of 30-foot retaining walls along the northern edge of the site, adjacent the neighbor's driveway. · Retaining walls will be needed along the edge of the bluff to provide adequate building pads and bluff preservation. · It will remove all of the vegetation within the wooded area in the northeast comer of the site. · It will negatively impact the character of the neighborhood. · It will require removing 88 of the existing 145 trees. The use of a private road is beneficial to the city and the site by eliminating multiple accesses onto Pleasant View Road, reduces grading impacts and preserves trees. The variance request meets the six required findings as follows: 1. Undue Hardship. The undue hardship is created by the topography of the site. A private road is not necessary for the development of the three lots ~vithin this site. It is possible to serve the site with three separate driveways or by a public road. Three driveways were not desirable due to the number of accesses onto Pleasant View Road and tree loss. A plan has been submitted that shows three lots being served by a public road. However, the steep grades and significant tree loss caused the public road to be environmentally damaging to construct. It is believed that a private drive will better serve the three lots and will minimize the grading impacts and tree loss. 2. Not applicable to other properties with same zoning This site is unique due to: 1) the steep topography, 2) having Pleasant View Road abutting two sides and 3) the inability to extend a public road past the site borders. Because of the site topography the private road will minimize the grading and tree loss within the site. The private road will also eliminate the number of driveways entering onto Pleasant View Road, which is expected to carry more traffic in the future. The ability to serve three lots with a single access than three accesses allows the development to improve traffic conditions in the area. Due to the location of the site and it's surrounding area it is not feasible to extend a public road beyond the borders of the site to serve any future developments. 3. Purpose is not to add value to the property Individual driveways without the use of a private road can achieve the same number of lots as allowed by city codes. The private road reduces grading and the number of accesses onto Pleasant View Road. 4. Not a self-created hardship The hardship is created by existing conditions. The development proposes to minimize the impacts to the existing conditions by using a private road. 5. Not detrimental to public welfare or surrounding properties. The use of the private road creates a public benefit by reducing the grading impacts and by minimizing the number of driveways onto Pleasant View Road. o Not impair adequate light, air, traffic congestion, or property value nor endanger public safety. The private road maintains the same number of lots and development impacts that is allowed without the variance. Approving the private road will help in traffic congestion and public safety by reducing the number of driveways onto Pleasant View Road, especially in this area where several roads intersect near a curve. R-O-W Vacation Oak Grove Avenue is a platted 15-foot undeveloped right-of-way located along the northern lot line. The road does not provide any practical benefit to the city or future access to the surrounding area.

The existing bluff limit line follows the entire west side of the proposed Lot 1 and the private street. The plans propose to grade about 75% of the site for the new house pads and a proposed private street with a half hammer- head turn around. The proposed grading will prepare the site for full basement and walk-out house pads. Drainage swales have been proposed along the sides of the houses to maintain the neighborhood drainage pattern through the property. The plan proposes a retaining wall for tree protection on Lot 1. The applicant should be aware that any retaining wall over 4 feet in height must be designed by a Structural Engineer registered in the State of Minnesota. Also, it will require a building permit from the Building Department. Staff is concerned with the proposed grading in the rearyard areas of Lots 1 and 2. There is a steep slope (3:1) in the rearyard of Lot 1 which drains toward the housepad. Staff has concerns about the ability of stormwater to safely drain around the housepad at the elevations shown. Staff would recommend that either the housepad be raised one foot in elevation or that a small, 2- to 3-foot, retaining wall be installed to better facilitate drainage away from the house. Also, the proposed rearyard of Lot 2 is a steep, vertical drop of over 20 feet from the housepad to Pleasant View Road. In order to provide a usable rearyard area, staff would recommend that a flatter, 10:1 slope be used for the first 15 feet off the rear housepad along with a 4-foot retaining wall. The existing site drainage is encompassed within two different drainage areas. The site drains off site to the east and west directions toward Pleasant View Road. Under developed conditions, the applicant is proposing to capture all of the rearyard drainage from Lot 1, all of the street drainage and all of the front-yard drainage from the lots. This stormwater will be conveyed via storm sewer to an existing pond at the corner of Horseshoe Lane. The proposed storm sewer must The City of Chanhassen · A qrowinq .... cornmunity w, ith clean lakes quality schools Sharmeen A1-Jaff March 8, 2004 Page 2 be designed for a 10-year, 24-hour storm event. To better treat the stormwater, the applicant is proposing a stormceptor manhole to provide additional water quality treatment of the stormwater. Tree preservation fencing must be installed at the limits of tree removal. All disturbed areas, as a result of construction, shall be seeded and mulched or sodded immediately after grading to minimize erosion. A 75-foot minimum rock construction entrance must be added to the entrance that will be accessed during construction. If importing or exporting material for development of the site is necessary, the applicant will be required to supply the City with a detailed haul route and traffic control plan. UTILITIES The plans propose on extending sewer and water from Pleasant View Road on the east side of the parcel. Overall, the utility layout looks fine. Upon completion of the utility improvements, the utilities will be turned over to the City of Chanhassen for maintenance and ownership. According to the City's Finance Department records, the parcel was previously assessed for one sanitary sewer and water hookup. Since the developer will be responsible for extending lateral sewer and water service to the lots, the sanitary sewer and water connection charges will be waived. However, the sanitary sewer and water hookup charges will still be applicable for each of the new lots. The 2004 trunk hookup charge is $1,458 for sanitary sewer and $2,814 for water- main. Sanitary sewer and water-main hookup fees may be specially assessed against the parcel at the time of building permit issuance. All of these charges are based on the number of SAC units assigned by the Met Council. Public utility improvements are required to be constructed in accordance with the City's latest edition of Standard Specifications and Detail Plates. Detailed construction plans and specifications must be submitted at time of final plat for review. The applicant is also required to enter into a development contract with the City and supply the necessary financial security in the form of a letter of credit or cash escrow to guarantee installation of the improvements and the conditions of final plat approval. Permits from the appropriate regulatory agencies will have to be obtained, including but not limited to the MPCA, Department of Health, MCES, and Watershed District. STREETS The plans propose on accessing the lots via a private street from the south side of the parcel off Pleasant View Road. The applicant is proposing a 30-foot private street easement with a 20-foot pavement width. The plans propose a 10% slope private street with a half hammer-head turn around. The proposed hammerhead turnaround configuration has been reviewed and approved by the City's Fire Sharmeen A1-Jaff March 8, 2004 Page 3 Marshal. In addition, the private street must be built to a 7-ton design. The developer will be required to submit inspection reports certifying this. Also, the existing driveway to the site off of Pleasant View Road must be removed. Pleasant View Road is designated as a collector road in the City's Comprehensive Plan. Current city code requires that collectors have a right-of-way width of 80 feet or 40 feet from the right-of-way centerline. Due to the existing environmental features (bluffs, trees, Lotus Lake) around Pleasant View Road and the tight space constraints of the area, it is unlikely that Pleasant View Road will ever be upgraded to the full width of current City standards for collector roads. As such, staff does not feel that a full 40 feet of right-of-way from the centerline of Pleasant View Road is needed with this development. In keeping with the dedicated right-of-way width for Pleasant view Road of previous plats to the east of this site, staff has recommended that the applicant dedicate the necessary right- of-way to obtain a 33-foot width from the centerline of Pleasant View Road for a total width of 66 feet. The applicant has shown this on the plans. RECOMMENDED CONDITIONS OF APPROVAL 1. Submit a 30-foot wide private cross access easement against all three lots at time of final plat recording. Permits from the appropriate regulatory agencies will have to be obtained, including but not limited, to the MPCA, MN Department of Health, MCES, and Watershed District. The storm sewer must be designed for a 10-year, 24-hour storm event. Submit storm sewer sizing calcs and drainage map for staff review and approval at time of final plat. The applicant should be aware that any retaining wall height more than 4 feet in height must be designed by a Structural Engineer registered in the State of Minnesota. Also, it will require a building permit through the City's Building Department. 5. Tree preservation fencing must be installed at the limits of tree removal. 6. Show all of the existing and proposed utility easements on the utility plan. On the grading plan: a. Show all existing and proposed easements. b. Show the benchmark used for the site survey. c.

Inlet control methods will be varied before and after pavement of the street. Before pavement, inlet protection could consist of heavy-duty mono-mono silt fence with 4-foot spacing of metal T-posts and 1" rock around silt fence material. After pavement, compost socks, sand bags or rock and wire could be used as temporary inlet control. Silt fence should be provided as needed to prevent sediment from leaving the site. Erosion control blanket should be installed on all slopes greater than or equal to 3:1. All exposed soil areas must have temporary erosion protection or permanent cover for the exposed soil areas year round, according to the following table of slopes and time frames: Type of Slope Time Steeper than 3:1 7 days 10:1 to 3:1 14 days Flatter than 10:1 21 days (Maximum time an area can remain open when the area is not actively being worked.) These areas include any exposed soil areas with a positive slope to a storm water conveyance system, such as a curb and gutter system, storm sewer inlet, temporary or permanent drainage ditch or other natural or man made systems that discharge to a surface water. Street cleaning of soil tracked onto public streets should include daily street scraping and street sweeping as-needed. Surface Water Management Fees Water Quality Fees Because of the impervious surface associated with this development, the water quality fees for this proposed development are based on residential single family r I The City of Chanhassen · A gre'¢,,ung son/ra.Jrdt, wi h clean lakes quality, schools a charming downtown, thriviug businesses, winding trails, and beautiful parks A great place to lye 'werk ahd [)lay Sharmeen A1-Jaff March 3, 2004 Page 2 of 3 development rates of $1,028/acre. Based on the proposed developed area of approximately 1.92 acres, the water quality fees associated with this project are $1,974. Water Quantity Fees The SWMP has established a connection charge for the different land uses based on an average citywide rate for the installation of water quantity systems. This cost includes land acquisition, proposed SWMP culverts, open channels, and storm water ponding areas for runoff storage. Residential single family developments have a connection charge of $2,545 per developable acre. This results in a water quantity fee of approximately $4,886 for the proposed development. SWMP Credits This project does not propose the construction of NURP ponds and is therefore not eligible for SWMP credits. At this time, the estimated total SWMP fee, due payable to the City at the time of final plat recording, is $6,860. Other Agencies The applicant shall apply for and obtain permits from the appropriate regulatory agencies (e.g., Riley-Purgatory-Bluff Creek Watershed District, Minnesota Pollution Control Agency, Minnesota Department of Natural Resources (for dewatering)) and comply with their conditions of approval. SUBDIVISION: RECOMMENDED CONDITIONS OF APPROVAL 1. Inlet control shall be provided following installation of inlet structures. 2.
