Zoning File #1921 April 14. 1994 Page 4 Grading and Drainage The probable house location on Lot 1 is in mid to lower slope of a hill. The drainage area above that site is less than one-half acre, hence any drainage concerns can easily be dealt with at the time a new’ house is constructed. The standard perimeter drainage and utility easements will be required on the plat drawings. Wetland A wetland exists in the northwest quadrant of the property. A review of the area topographic maps suggests that this is a pothole that would overflow to the north at elevation 987.1* under the 100-year storm conditions. The City ’s topographic mapping and the City ’s wetland boundary as depicted on maps in 1975 do not coincide. Staff recommends that the wetland boundary tor purposes of defining a conservation and flowage easement (which is required) be defined at the 98'^.!’ elevation contour which likely will correspond fairly closely with the actual wetland as it currently exists. As always, a 26 setback would be required from that contour line for any construction, changes in grade, etc. Since no grading, filling or draining of this wetland is proposed (or allowed by the City), it does not require Wetland Conservation Act review by the Watershed District. Park Dedicalion Fee The new Lot 1 will be subject to the standard park dedication requirement. This will be presented to the Park Commission for review. Staff is unaware of any trail needs for this area and anticipates that the park dedication fee of 8% of the pre-development fair market value of Lot 1 will be required to be paid prior to final plat approval. Staff Recommendation The property appears to meet all pertinent code requirements for subdivision to create a new buildable lot. A variance should be granted for the front lot setback of the e.xisting house. Any recommendation for approval should include the following conditions: 1.Prior to preliminary plat review by the Council, applicant's surveyor to stake and define on the preliminary plat drawing the 987.1* contour. 2. Conservation and flowage easement required over wetland. 1
