Alpine Woods Preliminary Plat Review Revised: April 23, 2004 of 4 1. Staff suggests that the public street between CR 57 and Uranium Street be named !55th Lane NW. If the stub street south of 154th Court is to be included in the plat it should be named 153rd Court NW. 2. Uranium Street (the northerly stub street) must be provided with a temporary road easement having a radius of 60 feet, and a temporary paved cul de sac having a radius of 50 feet. The plan submitted proposes that these dimensions be 55 feet and 40 feet, respectively. It is suggested that the bulb be offset to the north or the south and that one of the above lots be platted as an outlot until the street is extended northward. The temporary bulb may also be located on the property to the north if an appropriate easement can be obtained. 3. Similar to item #2 above, if 153rd Court is to be Platted is must also contain a temporary cul de sac. Alternatively, this future street could be platted as an outlot. 4. Information on the horizontal and vertical curves for the street must be submitted. 5. A sidewalk pedestrian ram should be added to the sidewalk crossing from 155th Lane to Uranium Street. This may require that the drivewayto the existing home on Lot 2 Block 4 be relocated slightly to the north. 6. The storm line CB7 to CB8 must be changed from a 12 inch pipe to a 15 inch pipe. The line f?om CB 11 to CB 12 may be a 12 inch pipe. 7. The two inlets into Pond A should be combined, or the inlet/outlet arrangement should be redesigned to reduce the potential for short circuiting. Access to Lots: The proposal includes a public road that gains access to the plat from 153rd Lane NW and CSAH 57 (Sunfish Lake Blvd.). The Sunfish Lake Blvd. access will be directly across the street from an access to the Alpine Acres townhome development. The proposal also provides for a future connection to the remainder of High Point 2nd Addition to the north. Staff has submitted the preliminary plat to Anoka County for review and comment. The right-of- access along Sunfish Lake Blvd. will need to be dedicated to Anoka County. All existing residences to remain after platting will need to be rerouted to the local residential street. It should be anticipated that additional turn lanes will be required by the County as a condition for the access onto CR57. Noise Mitigation: The review letter from Anoka County notes that residential noise standards may be exceeded and that County policy prohibits the expenditure of highway funds for noise mitigation efforts. The City should consider whether to require an analysis of the potential for the noise standards being exceeded, and requiring the developer to install appropriate noise mitigation measures, or whether the City wishes to adopt a policy similar to that of the Couhty to prohibit the expenditure of funds for noise mitigation measures adjacent to County highways. Staff recommends the latter option. Either such a policy should be adopted prior to final plat approval, or the development agreement should contain a provision for analysis and mitigation with regard to noise standards. Utilities: All lots are proposed to be served by municipal sewer and water which would access the plat from the Alpine Acres development to the east. A 30-inch sanitary sewer has been brought to the west side of Sunfish Lake Blvd at a point approximately 70 feet north of 155th Lane. The sanitary sewer utility plan shows this trunk sewer to be extended along CR57 to the north line of the plat, and then west to the west plat boundary. The exact route for the extension of the trm~ sewer
