Prelirnirzary Plat and Site Plan Review: Ebony Woods August 31, 2006 Revised: SePterrrber• 22, 2006, December Z0, 2006 Page 3 of 6 October 10, 2006 work sessio~a: consider using different colors for each building, other materials to make them appear to be 3 distinct builduigs rather than 6 separate units. Add stone to the elevations. Some concern about six units versus four units. November 14, 2006 Cou~zcil nieeti~.g: looking for higher-end architecture, possibly staggering buildings to avoid long wall of ants. Still some concern about six unts versus four uluts. Staff recommended wrapping the brick and shakes around the sides of the building. The most recent submittal (marked as 3ra submittal in the Council case) shows the brick and shakes wrapped around the sides of the building as requested by Staff. Staff continues to have some concerns about the dominance of the garages on the units and will be seeking additional direction from the City Council on the elevations. 9: Streets: All six units will have direct access to Ebony Street, a dedicated and improved public street. Ebony Street is not a collector street for which driveway accesses are restricted or limited. City Staff fords this access plan acceptable plan acceptable. Street and sidewalk impacts caused by the development will need to be restored by the Developer. 10. Grading and Drainage: A drainage and grading plan dated August 3, 2006 has been prepared for this development by Brad C VJilkening PE. This plan proposes that drainage from the development will be drained to Ebony Street which in turn drains to the Mississippi River. The Mississippi River Overlay District regulations state that it must be shown that the proposed development will not increase the runoff rate or decrease the natural rate of absorption of storm water. The Department of Natural Resources has commented that the additional runoff from this site should receive treatment before flowing to the Mississippi River. Staff recommends that a detention pond be considered in the center of the site which could overflow into the catch basin located on the east side of Ebony Street. An effort should be made to locate this pond such that it would have minimal impact to the significant trees located on the site. In addition staff offers the following comments on the grading plan: • All grades must have a minimum slope of 1%. Several areas have grades which are below this minimum. Any lots havuzg grades flatter than 2% will require a certificate of grading prior to the issuance of a certificate of occupancy. • Contours shall be provided for a distance of 100 feet beyond the boundary of the site. • If a pondis added to the plan the location and elevation of the emergency overland flow outlet shall be identified. • Pre and post runoff calculations should be provided. • A table specifying the following information should be added to the grading plan: house type, garage elevation, minimum floor elevation, lowest floor opening, street centerline grade, and backyard and front yard slopes. • A permit for this development will be required from the Lower Rum River Water Management Organization. A revised grading and drainage plan is required as part of the final plat submittal. -237-
