7, 10. .Access to Lots: Alt lots in tile plat would be accessed by interior streets; no lots would have direct access onto State Hwy. #47. Street. s. In accordance with tile approved preliminary plat, the dead-end extension of Argon Street N.W., south of 147th, is approved at a length of approximately 850 feet. The City's transportation plans call for a 120 foot right-of-way for ma)or arterial, which would require the developer to dedicate 60 feet from the center of T.H. #47. The preliminary plat shows 50 feet is proposed to be dedicated. In light of the fact that ,:10 feet of park has been dedicated adjacent to the right-of-way, Staff feels the 50 foot dedication for T.H. #47 will be adequate. In accordance with Staff's recommendation, the plat has been designed to provide a street outlet from this subdivision onto T.H. #47 that will align with the future intersection of Sunfish Lake Drive and T.H. 847. Park Dedication. The proposed plat was reviewed by the Park and Recreation Commission on February 11. It is recommended that park dedication consist of land dedication and development of 8 foot wide hardsurface trails from the southwest corner of the pla~ travelling north and east through the plat to connect with Juniper Woods. Park dedication credit will be given for all areas dedicated for trail purposes outside of street right-of-way and the value of constructed improvements. Any remaining park dedication due would be satisfied by the developer continuing the constructed trail improvements from the north boundary of Amber Ridge, through Juniper Woods to 153rd. Landscaping. In accordance with the City's request, the grading plan does indicate that a six (6) foot berm to buffer the single family homes and trail from Hwy. #47 will be provided. The developer is in the process of preparing a landscape plan for the berm which will include tree plantings as part of the City's ReLeaf Grant. Drainage and Wetlands. A grading and drainage plan has been prepared which provides for collection and transmission of storm water to sedimentation basins and low wetlands prior to ultimate discharge into the Rum River via two outfalls. The drainage plan, as well as the proposal for filling and replacing 0.14 acres of non-protected wetland has been sent to the Lower Rum River Water Management Organization (LRRWMO) for permitting. Approval of the subdivision drainage plan and wetland mitigation is anticipated within the easement provisions of the final plat document. However, in the event additional easements are necessary to facilitate the drainage provisions required, the development a~eement requires the developer to convey by separate document any additional easements that may be required. Extension of Sanitary Sewer. In order to service approximately fifteen (15) lots in the northwest corner of the plat, it will be necessary to extend a trunk sewer by gravity flow. The necessary sanitary trunk sewer is identified on the City's comprehensive sewer plan. We therefore recommend that this trunk sewer be extended by the Developer with a credit for the cost of the installation being given against the amount of trunk sewer and water charges. The proposed development agreement addresses the details for determining the basis of the credit and the terms for payment to the City of the anticipated trunk charge balance,
