Staff. has contacted the State regarding their suggested for construction of a northbound bypass lane at 160~. First of all, they meant to say 157% not 160% And in subsequent conversations, it has been determined by Mn/DOT Staff and the City Engineer that the construction of a bypass lane at 157~' cannot be a contingency of the development as River Pines 5~' is not the only factor creating a need for the bypass lane and the cost of said construction is not proportionate to the benefit River Pines 5t~ would receive. Lot Size and Dimensions: In accordance with the approved preliminary plat, all of the lots meet the minimum area and width requirements. Grading and Drainage: A Final Grading Plan prepared by Passe Engineering has been submitted to the City. The plan indicates the addition of one pond east of Lithium Street N.W. to handle the increased runoff caused by the development. This pond as well as a 20. foot easement for access is being shown as a drainage and utility easement. The ponding calculations required at the time of preliminary plat approval have been provided but do not specify the water elevation for a 100 year elevation for Block 2. The lowest floor elevation shall be 2 feet above the 100 year elevation. The plan still needs to be reviewed and permitted by the Lower Rum River Water Management Organization (WMO). It should be noted that the W'MO has requested further information to justify curve numbers greater than 39 that are used for calculations for pre- development conditions on previous Ramsey subdivisions. No construction activity shall occur without evidence of a WMO permit. The City has enacted an ordinance that requires an elevation sUrVey at the time of footing inspection to ensure compliance with the approved final grading plan. The grading plan shalI identify which type of house style (i.e. walkout, lookout, rambler, otc) is permitted on each lot. No grades shall be flatter than 1%. Grades flatter than 2% will require a certificate of grading prior to an occupancy permit being granted. Lots 1, 2, 6 and 7 of Block 2 currently are shown to be flatter than 2%. The requirement for an elevation survey on all footing inspections and the requirement for a certificate of grading on lots with less than a 2% grade shall be stated on the final grading plan. The grading plan proposes to provide an overflow from the pond to the east. Discharge of water over T.H. #47 right-of-way will require a Mn/DOT permit as mentioned in their review letter. -163-
