Planning Commission Report Silver Lake Commons Development Review • Planning Case No. 487-97 July 16, 1997 Page 3 The second concern regarded a lack of calculations to indicate that the storm sewer under the southernmost drive (not shown on plans) could accommodate 100-year flows. The applicant has verified that the size of the pipe is adequate and will provide calculations to support this assertion before your meeting. Landscape Plan: The plans submitted by the applicant on July 1, 1997 include a revised landscape plan which shows some of the changes that were suggested at your June 18, 1997 meeting. With regard to the specific plantings, only two changes still need to be made. First, the plan does not show any landscaping fronting Highway 10 south of the access drive. Depending upon availability, the applicant will need to show a row of Dwarf Korean Lilac – trees or Anthony Waterer Spirea in this location. Second, •R; 2 e �O Regal Elms should � the be replaced with Hackberry, as was 7 - � suggested by the City Forester Rick Wriskey. Staff ' recommends making four other changes to the landscape ' t y` �0 and site plan. First, the 26-unit -' y� garage building should be � --c`, positioned 18 feet to the east so that plots of greenspace I e9 • % . remain at either end. This may result in the loss of the seen 111 existing elm tree shown on the plans. If this tree can not be I retained, a flowering snow crab should be planted in its eti ' "n� place and additional flowering snow crab should be planted t _ in the newlycreated greenspace. t e , This greenspace could be1. l S,p used for parking stalls if needed in the future. Second, a seC•MNC '� — — �– s gate should be added to the chain link fence at its - "°" �—LINE.OF 0 northernmost point along Eastwood Road to allow for Figure 2 Proposed sod line pedestrian access and a possible school bus stop. A path should be added linking the parking area to Eastwood Road. Third, staff recommends that the sod line (denoted by the thin dashed line) be realigned to encompass the play structure as shown in Figure 2 above. Last, the three black hills spruce proposed along Eastwood drive in the seeded play area should be moved closer to the fenceline to allow for a larger, unimpeded play area. Access: The Minnesota Department of Transportation(MnDOT) is requiring that the applicants add a right turn lane off of Highway 10 to the development and an acceleration lane for right-turns exiting the development. The letter from MnDOT is attached. To do this and to remove the existing driveway and culvert, the applicants will need to obtain a permit from MnDOT. This shall be done prior to the City issuing building permits for this project. Parking: The parking ratio required for multiple family residential units is 2.5 spaces per unit, with one of the • spaces in covered parking. The total number of spaces required for this project would be 56 garages and 84 surface spaces, for a total of 140 spaces. The applicants propose 57 covered garage spaces, one more than what is required for the proposed 56 units (40 units Red Oak
