Staff is also recommending that the applicant address noise impacts to the development due to its proximity to Highway 5. FINAL PLAT PROPOSAL /SUMMARY The applicant is requesting final approval for a Planned Unit Development to rezone 12.34 from Agricultural Estate, A2, to Planned Unit Development, PUD (final reading) and final plat of Outlot A, Autumn Ridge Addition, creating 25 lots for Autumn Ridge 2nd Addition. The development consists of a site plan for a residential medium density development consisting of 1 two -unit, 2 three -unit, 2 four -unit structures, 1 six -unit structure and 9 eight -unit structures subject to the plans dated June 21, 1995, revised September 21, 1995 prepared by Passe Engineering, Inc. WETLANDS The site is bordered by a DNR protected wetland (10 -210W) along its westerly border. A buffer - strip. has =been. - incorporated -into the - grading - plan - providing: a,- 20�faota erage width:adjacent�the wetland. The City's trail meanders through the buffer area and therefore additional buffer areas should be set aside to incorporate the trail. The overall average should be 28 feet versus 20 feet. 7 Don Ashworth, City Manager ' February 22, 1996 Autumn Ridge 2nd Addition Final Plat Page 11 Another wetland is located in the northeast corner of the site and is characterized as an ag /urban wetland. This basin, which is approximately 0.3 acres, will be filled as a result of the proposed development. Mitigation for this wetland is permitted under Wetland Alteration Permit No. 95- 4. SURFACE WATER MANAGEMENT PLAN (SWMP) Water Quality ' The applicant has supplied detailed construction plans for stormwater management of this site. pp pp p g ' The plans propose a regional stormwater treatment pond to be constructed just west of the development adjacent to the wetlands. The pond is being constructed within the City's park land. The pond is designed in accordance with the City's Surface Water Management Plan and will serve both phases of Autumn Ridge 1 st and 2nd Additions. Since the pond is being constructed within the City's park land, the applicant will be responsible for compensating the City for use of the park land. Based on the SWMP land dedication chart, the property value for ' this type of land use is $24,000 per acre. This results in the applicant owing the City $12,000 for the use of the park land for ponding. This fee should be collected at time of final plat recording. Since the applicant is constructing the pond, stormwater quality connection fees will be waived. ' Stormwater Quantity Fees The project will be charged a water quantity connection fee based on medium density land use. The applicant will receive credit against the fee for providing the outlet control structure in the regional stormwater pond. The connection charge for medium density development has been ' established at $2,975 per developable acre. Based on 12.3 acres of development and applying the credit for the stormwater outlet control structure, the applicant is responsible for a water quantity connection charge of $33,092. These fees are payable to the City at time of final plat ' recording. DRAINAGE Staff has received detailed drainage and pondmg calculations. Storm drainage improvements are ' proposed to convey runoff from the site to the regional stormwater pond for pretreatment prior to discharging into the wetlands. During plan review, staff found that a couple of additional catch - basins - are - needed -as well- as- shifting.> the- stor- mwater- p©ndMslightly- to -aliaw €or- the•tr- ail - adjacent ' to Coulter Boulevard. These changes will be incorporated into the final construction plan review process. Overall, the drainage plan is in general conformance with the City's SWMP. 1 Don Ashworth, City Manager February 22, 1996 Autumn Ridge 2nd Addition Final Plat Page 12 GRADING Both Autumn Ridge 1 st and 2nd Additions are proposed to be graded this spring. The grading plan has been modified to incorporate berms along Coulter Boulevard, Galpin Boulevard, and Trunk Highway 5. The grading plan will need to be modified to provide a boulevard area along the north side of Coulter Boulevard for the trail as well as additional berming. EROSION CONTROL The applicant's engineer has developed a sediment and erosion control plan in accordance with the City's Best Management Practice Handbook. Type III erosion control fence will be installed adjacent to the wetlands. The regional stormwater pond will be graded first to act as a sediment basin until the site is fully graded and revegetated. All disturbed areas as a result of construction are proposed to be reseeded and mulched within two weeks after grading is completed. Additional erosion control measures will be employed around catch basins to protect them during construction until the streets are paved. UTILITIES Detailed construction plans were submitted to staff for review and formal approval by the City Council. Staff has reviewed the construction plans and finds them in general accordance with City standards. Staff has returned the initial set of construction plans to the applicant's engineer for additional revisions. Upon completion and acceptance of the utilities, the City will own and maintain the utility systems. Drainage and utility easements have been dedicated on the final plat over the utility areas. STREETS The applicant has also submitted street construction plans and specifications for Coulter Boulevard in conjunction with Autumn Ridge 2nd Addition. Coulter Boulevard is proposed to be constructed from Galpin Boulevard (County Road 19) to the west edge of Block 1. The plans for Coulter Boulevard are subject to MnDOT State Aid approval. A condition has been placed in the PUD /development contract that final plat approval is contingent upon the applicant receiving ' the^ necessary pconstruction*pplan- appprovals from MnDOT State -Aid of€rce. MnDOT has - already approved the alignment of Coulter Boulevard. Since Coulter Boulevard will eventually be extended to Trunk Highway 41 in the future, a condition shall be placed in the PUD /development agreement notifying property owners that Coulter Boulevard will be extended in the future. i1 d I"1 �J Don Ashworth, City Manager February 22, 1996 Autumn Ridge 2nd Addition Final Plat Page 13 ' The interior streets are fairly well laid out from a traffic circulation standpoint. The interior streets all connect back out to Coulter Boulevard. All of the streets which branch off Coulter Boulevard are proposed to be private streets and not maintained by the City. The private streets shall be constructed in accordance with the City's private driveway ordinance. The minimum street width for multi - family zoning is 24 feet face -to -face with concrete curb and gutter. Some of the driveways, serving four or fewer units, will be 20 feet wide. Parking will be prohibited on all of the private streets as well as Coulter Boulevard. The City Council should adopt a resolution prohibiting parking along Coulter Boulevard. Since there will be ublic improvements constructed in conjunction with this development, the P p J p applicant will be required to enter into a PUD /development agreement with the City and provide the necessary financial security and administration fees. Street lighting is also required within the development and along Coulter Boulevard. Staff will work with the applicant to develop a street lighting plan and the applicant shall be required to incorporate it into the street construction plans. MISCELLANEOUS t MnDOT's policy is to assist local governments in promoting compatibility between land use and highways. Residential land use adjacent to highways will usually result in complaints about traffic noise. The Minnesota Pollution Control Agency has established noise standards and the U.S. Department of Housing and Urban Development also has guidelines. Traffic noise from this highway could exceed noise standards established by these agencies. MnDOT policy regarding new developments adjacent to existing highways prohibits the expenditure of highway funds for noise mitigation measures. MnDOT will not be constructing any noise abatement structures as part of the upcoming T.H. 5 project. The developer should assess the noise situation and take the action deemed necessary to minimize the impact of any traffic noise. LANDSCAPING AND TREE PRESERVATION The site is primarily devoid of trees except in the northeast corner and near the wetlands. The rsignrfteant -tree °inventory -of- the - site -veriftes--rhese° tree- typesrectnsisting- of-maples,-oaks, box elder, and elm. Conifers have been planted in the area of the farmstead. City ordinance requires a canopy coverage of 20 percent for medium density residential developments. The only significant tree preservation proposed on the site is in the northeast Don Ashworth, City Manager February 22, 1996 Autumn Ridge 2nd Addition Final Plat Page 14 corner of the property and along the northern portion of the site within the Highway 5 right -of- way. Additional trees have been preserved along Galpin Boulevard and in the southwest corner of the site due to site revisions. The landscaping plan provides 256 trees which would exceed the fore station/replacement requirements. There are 13 different tree species included in the plant schedule. Of the total number of trees provided, 69 trees are ornamentals (27 percent), 127 are conifers (50 percent), 4 are primary species (2 percent), and 56 are secondary species (22 percent). Staff has two concerns with the landscaping plan. The first is the distribution of tree species. Only 24 percent of the trees are either primary or secondary species, half the trees are conifers, and 27 percent are ornamentals. The second issue of concern is that the landscape screening for this development is being provided primarily by the evergreens that are being preserved within the Highway 5 right - of -way. To resolve both of these issues, staff is recommending that a more equitable distribution of trees be incorporated into the landscaping plan, specifically 20 percent ornamentals, 30 percent primary and secondary and 50 percent conifers, and that additional groupings of evergreens be planted along the northern project boundary to prepare for the possible future removal of the evergreens with the widening of Highway 5. Conifer trees shall average seven feet with a minimum height of six feet. PARKS AND RECREATION The Park and Recreation Commission met on August 22, 1995 to discuss this development. They recommended the following conditions: 1. Full park dedication fees shall be collected per city ordinance. 2. Trail fees for Autumn Ridge 2nd Addition, and retroactively for Autumn Ridge 1 st Addition, be waived in consideration of trail construction. This trail construction shall be completed per city specifications within an alignment approved by the city.
