Preliminary Plat Review: .Alpine Meadows January 31, 2002, Revised March 28, 2002 Page 3 of 4 and the T.H.: #47 service road, which in mm drains overland to protected Wetland #658W.. This wetland has an outlet to the Rum River. Storrnwater generated from the development should be routed tO the e,-dsring pond. From review of the drainage ptan, it appears the development meets this requirement. A grading plan has been submitted with the preliminary plat. Under City Ordinances, all yard g'rades shall be no tarter than one percent. Grades between one and t,a.o percent require a certificate of grading before the units can be funy constructed. The grading plan · proposes grades of less than one percent behind Lots 14-22, Block I and Lots 9, 10, I3, 14, 17,-and 18, Block 2. These ~ades must be modified to a mirJmum of one percent. Critical swale =.re'aries should be annotated to the grading plan at the ex-tension of each end The no~heast comer of the parcel will have standing water as it will remain lower than the surrounding and proposed grades. The ~ading plan should be modified to correct th/s deficiency. Based on an inspection of the National Wetland Inventory map, there appears to be no wetlands on this property. This project is also subject to the review and permitting process of the Lower Rum River Watershed Management Organization CLR.R.WMO). Please contain Steve .rankowski to discuss the submittal deadlines and requirements for the LRRWNfO, . Traffic Generation Analysis: The City may require a traffic, analysis to be conducted for the development if it is deemed necessary. Utilities and Water Usage: The development will be served By municipal water and sanitary sewer. Currently, utilities exist on the property. However, they are without drainage and utility easements. The final piat shall show drainage and utility easements of 'sufficient width where sewer and water lines are located. It appears that Lots 14 through 22, Block 1, may encroach in the easement width necessary to protect the e,,dsting 15-inch srorrn sewer. From staff' review, it appears that it may be difficult to have decks on the units in Lots I4-22. Please contact City Engineer Steve Jankowsld regarding the required. widths of the easements. Park and Trail Dedication: The Park Commission has reviewed the proposed subdivision and is requiring that park dedication fees in the amount of $1700 per unit be collected in lieu of land dedication; thai trail fees in the amount of $400 per unit be collected; that the developer indicate an area within the subdivision of common open space that can be used for active or passive recreation, and that the applicant dedicate through a separate recordable document a twenty-foot trail easement parallel with State Hwy. 47. -12-
