-194- Site Plan Review: Ramsey Townhomes Page 2 of 5 November 3, 2000 Revised November 17, 2000 10. Setbacks: In the interpretation of the R-3 Urban Residential setback requirements, it would appear that in this case the rear yard setback is from 40 feet from the outer boundaries of Lot 1. Because such a significant amount of the site is encumbered with wetlands and a collector street, staff is recommending applying the 25-foot minimum setback to the structures. Ali of the proposed structures meet the 25-foot setback. A variance is required to reduce the 40- foot max/mum'rear yard setback to the 25-foot minimum setback. Densit'v: The site plan is proposing to construct a total of.31 townhome units on Lot I. TNs equates to a gross density of 2.7 units per acre. In the current draft comprehensive plan, this property is targeted for high-density residential development and high density development has been established at a maximum of 7 units per acre. Access: The entire development has access provided at a single point. The interior roadway with/n the development will be 24-foot wide private streets. Parking will need to be restricted on both sides of the private streets with signs and painted curbing. It is also recommended that B6/12 curbing replace the surmountable curb and gutter proposed. Access for emergency vehicles should be provided at least at one, and preferably at both ends of the cul-de-sacs. Grading. and Drainage: The grading plan proposes draining both the north and south ends of the site overland to catch basins located in the east/west access road into the site. These catch basins in turn are proposed to be discharged directiy into a storm sewer provided within Sunwood Driv.e. Calculations must be submitted to ensure that the runoff generated by the development will be sufficient to be handled by the storm sewer provided in Sunwood Drive. A permit must be obtained from the Lower Rum River Water Management Organization for this development. REU Number: According to the calculations for impervious area, provided to us by Hakanson Anderson, the R.EU for tiffs property would be 10.18. This results in a storm .drainage utility charge of $256.54/quarter. TNs would be equally distr/buted amongst the 30 dwelling un/ts in the development. Each dWelling unit- would rgceive a quarterly storm drainage utility bill of $8.54. This does not include any internal sidewalks so if these are added in the future the REU would increase accordingly. Wetlands: The lands west of Sunwood Dr/Ye are predominately occupied by DNR protected wetland 658W and are proposed to be encumbered by a drainage and utility easement. Landscaping: Thirteen summit ash trees are shown for the proposed 30 towr&ome un/ts. In order to meet minimum requirements, 19 additional trees wiI1 need to be planted in the front I I I I I I I I I'
