§ 20-1556. Impervious surface, lot coverage and slopes.

(a)

To the greatest extent possible, all development shall minimize the amount of lot coverage by clustering development, using common access drives and utility corridors and minimizing building footprint size. Roads, walkways, bike trails, and parking areas must be designed parallel to natural contours with consideration to maintaining consolidated areas of natural topography and vegetation. Management of surface runoff caused by impervious surfaces shall be designed using practices delineated in the city's surface water management plan.

(b)

Within the secondary zone of the BCO district, areas with average slopes exceeding 25 percent shall be preserved in their natural state and maintained as permanent open space. Areas with average slopes less than 25 percent but greater than ten percent shall not exceed 25 percent lot coverage. Lot coverage for areas where average slopes are less than ten percent shall be governed by the underlying zoning district.
