The Meadow: Final Plat Review February 22, 2006 2of$ The request to rezone the new residential lots to Planned Unit Development will permit the flexibility in lot sizes. The minimum lot width is 80 feet; the lot widths range from 58 feet to 146 feet in width; the majority of the lots are at least 70 feet in width; this flexibility in lot width was also approved as part of the rezoning to Planned Unit Development. Density: The R-1 Residential regulations for the MUSA area allow a net density of 3 units per acre or 4 units per acre as a Planned Unit Development. The residential portion of the plat (46 new lots and 3 existing residential lots) consists of approximately 21.5 acres. The goss density for the residential section of the project is approximately 2.3 units per acre. Net density is typically calculated as the total plat area minus any wetlands on the site. There are no wetlands on the site and therefore the net density is 2.3 units per acre. Easements: The existing trail easement along Alpine Drive is being preserved. There is an existing easement for the overhead power lines along Alpine Drive that is also shown on the final plat. All building pads are appropriately located outside of these easements. The standard I0 foot (5 feet on common property lines) drainage and utility easements are being shown on the final plat. Traffic Analysis Report: The City Charter requires a traffic analysis report for this development. The traffic analysis report indicates turn lanes w/Il be required at the intemection of Sunwood Drive and CSAH 5 (Nowthen Boulevard). This intersection is not adjacent to the site so the work may have to be undertaken as a city- county project. The Study also indicates part of CSAH 5 will need to be upgraded to 4 lanes in the future. Grading and Drainage Plans: The final grading and drainage plans have been reviewed. Detailed comments are contained in the attached plan review memo from Leonard Linton to Keith Willenbring, dated February 2I, 2006. General comments are outlined below. The City of Ramsey does not require rock construction entrances as they are ineffective with the native soils. The erosion control plan must be revised to require daily sweeping of adjacent streets during active construction and as directed by the City. The drainage from the back yards of Block 3 is directed off site without rate control. The drainage from the back yards of Block 4 is also directed off site without rote control. The outlet pipe from Ponding Basin No. 2 is directed off site to a pond in a drainage and utility easement. The emergency overflow shown does not discharge to a drainage and utility easement. Ponding basin No. 2 and the existing pond must provide storage for back to back 100 year storms with out discharge. Several of these comments were provided during the preliminary plat review. They must be addressed prior to approval of construction plans. -130-
