-286— Preliminary Plat: Skyline Pointe June 30, 2006 Revised August 4, 2006 Page 2of8 Access and Streets: Skyline Pointe proposes to gain access off of both 151 Lane and Alpine Drive. The intersection of Alpine Drive and the street labeled as Pointe Drive has been moved west to establish a distance of 250 feet from the intersection of Alpine Drive and Nowthen Boulevard. Additionally, a series of private streets are proposed to access the proposed townhomes. The road labeled Kingsway Circle is a permanent cul -de -sac that is approximately 550 feet in length, and conforms to City Code. All streets must follow the City Street Naming Grid. Please revise Pointe Drive to Osmium Street. Please revise North Stering Drive to 151 Circle and Kingsway Circle to Potassium Circle. Sidewalks: Sidewalks are required on at least one side of all public streets. A sidewalk is proposed along the north side of 151 Lane from the west plat boundary to Nowthen Boulevard and along the east side of Pointe Drive. Traffic Generation Analysis: The traffic generation report has been submitted for the proposed Skyline Pointe Development. The report indicates that this development will produce 350 additional cars per day, half of which will enter onto 151 Lane. However, the majority of cars will pass the intersection of 151 Lane and Nowthen Boulevard. Anoka County's Highway Department will also have the opportunity to comment regarding this development. It should be expected that the County will require the construction of turn lanes on Nowthen Boulevard (CSAH 5). Grading: A two sheet grading and drainage plan has been prepared by LHB Inc. Staff has reviewed this plan and offers the following comments: • The emergency overflow elevations do not appear to appear accurately of the plan. • Spot elevations are requested along the paths and at the street to help determine yard grades to insure adequate drainage. • Street high points and slopes grades should be added to the plan. Drainage and Stormwater Management: The drainage from the proposed development is directed into three distict ponding systems prior discharge into wetland 114P which borders the site on the west and north. Drainage from the southernmost portion of the site is directed into ponds A 1 and A2 prior to overflow into the wetland to the west. The drainage system proposed would include the redirecting the catch basin which currently drain 151 Lane into the drainage and utility easement that is located on lot 3 block 1 of the Juskiewicz Addition adjacent to the proposed development. This existing storm sewer would be abandoned. The middle portion of the proposed development would drain to Pond B and also overflows into wetland 114P. The northerly portion of the site drains into Pond c l and overflows northward across Alpine Drive into a segment of Wetland 114 P. A permit must be obtained from the Lower Rum River Water Management Organization. Utilities: The development will be served by municipal sanitary sewer and watermain. The sanitary sewer will be extended to the site from the trunk sewer line which is located
