15-3739 May 18,2015 Page 7 of 9 Lot 1, Block 3: The lot is shown to have 3.01 total acres and 2.85 dry, buildable acres in area. It is proposed to have approximately 220 feet of frontage on Hunter Drive where it will gain access. It appears that all building setbacks could be met for a principal structure on this lot. Much of this lot is covered with established prairie vegetation; there is a wetland on the eastern lot line. Applicant's Conservation Design Report Comments: Prairie grass preservation area over tlie first 1 SO'from the western boundary going east except for septic usc�ge. 30' preservation from the eastern boundary for prairie also. Buffer trees are also to be plante�l by deveJoper. Lot is accessed from Hunter Drive. Lot 2, Block 3: Like Lot 1, Block 3, this lot will front and gain access via Hunter Drive. It is shown to have approximately 270 feet in width and has 2.95 total acres of which 2.61 are dry. It also is currently primarily established prairie vegetation and has a wetland along the rear (east) lot line and along the south lot line. It appears that building setbacks can be met for a principal structure on this property. Applicant's Conservation Design Report Comments: Prarie grass preservation over the first l50'from the western boundary going east exceptJ'or septic purposes. Also a 40' southern boundary and a 30'easterly boundary shall be in place to furtlzer preserve the prarie. The developer is to p/ant trees to protect and preserve the valuable view corridor that's been enjoyed for 50+years. Access is from Hunter Drive. Road Layout and Standards There are two proposed private road corridors (Outlot E and Outlot F) serving the proposed subdivision. Both are shown to be 50 feet in width. Both proposed roads are shown with a 100' diameter cul-de-sac as required by the Subdivision Ordinance and the CMP for a local private road. The standard paved width for the road in Outlots E and F would be 24 feet with an 80 foot diameter paved cul-de-sac. Proposed Outlot F appears to require significant filling & grading and has potential impact on the septic sites for Lot 5. Total length of road in Outlot F is about 1550', exceeding the code standard maximum length of 1000'. The driveway to serve Lot 2 Block 2 adds an additional 600 feet. While applicant has suggested that use of the existing roadbed is desired, the minimum width for the entire road should be no less than 24 feet, as noted in the City Engineer's comments. The 30' access corridor shown for Lot 2 Block 1 would function as the access to the back lot. For Lot 2 Block 2 the access corridor has been widened to allow for flexibility in driveway placement to avoid tree removal. Road Improvements and/or Easements Needed The City will require a Road, Drainage and Utilities Easement over the private roads. Standard perimeter drainage and utility easements will be required along all property boundaries in the plat as well as Conservation and Flowage Easements over any delineated wetlands and drainageways.
