Final'Plat and Site Plan Review Shade Tree Cottages June 9, 2006 Page 2 of 4 requirement, the proposed development would need to provide a minimum of I4 acres of private open space. It would seem appropriate to only credit 50% for the wetlands when calculating private open space area. The fmai site plan is sl~owing a total of 50.2% private open space area. 6. Utilities. This development will be served with municipal sewer and water. Detailed comments regarding the utility plans are included in the Engineer's Memo dated June 9, 2006. 7. Access and Streets, The development is proposing to connect to Radium Street in Halls Dover Acres to the north and to Potassium Street from the south. Potassium Street is currently unpaved and will be upgraded to an urban section in order to serve this development and the Rum River Meadows development. The construction of Potassium Street 'grill be a coordinated project between Shade Tree, National Growth, and the City of Kamsey. The Costs for acquiring and constructing Potassium will be cost shared in the following manner: City of Ramsey- 50%, Shade Tree Commun/ties -25%, National Growth, LLC -25% The private street is 635 feet long. City Code states private streets over 300 feet in length must be 32 feet wide. The development is being processed as a PUD and deviations are permitted. The deviation from private street standards allows a slightly larger green area between the existing residential development and the proposed single unit detached town_home units. The 28 foot wide street will be acceptable if is posted for no parking on one side of the street. The public street servicing the single family homes is proposing to be 660 feet in lengxh, which exceeds the City's 600 foot maximum cul-de-sac length. Again this development il proposing to be processed as a PUD and therefore deviations are permitted. A temporary access plan will need to be approved by the City as the streets and utilities are constructed in order to ensure access for the existing residents of Potassium St. Additional comments about the street plan are contained in the Engineer's Memo dated June 9, 2006 8. Grading and Drainage. Grading, Drainage and Utility plans dated May 19, 2006 have been prepared by Midwest Land Surveyors and Engineers. We have some specific cormments regarding these plans: The plans show retaining walls adjacent to the private street. The city requires engineered plans for retaining wails four (4) feet tall and b_igher and the installation of fences at the top of the retaining wail. The watermain shown on the plans is PVC. The city standard for watermain is DIP. Th/s must be revised on the final plans. · A permit must be obtained from the Lower Rum River WMO to insure the adequacy of the storm water system and erosion control measures. · Additional comments about the ~ading and drainage plans are contained in the Engineer's Memo dated June 9, 2006 9. Wetlands: Staff is pleased to see that wetland buffers are proposed around most of the wetlands within this site. Areas that do not have sufficient existing vegetation (either trees or a dense layer of perennial grasses that have been uncultivated for at least ten years) shall be seeded in accordance with Mn/DOT's seed -260-
