B. Minimize Water Runoff & Concentration . All built-upon area shall be designed and located to minimize stormwater runoff impact to the receiving waters and minimize concentrated stormwater flow. C. Open Space Area . The remainder of the tract/property shall remain as an open space area in a vegetative or natural state. Where the development has pending corporative property owners’ association (homeowners’ association), the title of the open space area shall be conveyed to the homeowners’ association and is not incorporated, a maintenance agreement shall be filed with the property deed(s).
(4) Buffer Areas Required . The following buffer requirements shall apply:
A. Riparian Buffers . A minimum 50 feet vegetative buffer for development activities is required along all intermittent and perennial waters indicated on the most recent versions of U.S.G.S. 1:24,000 (7.5 minute) scale topographic maps identified as a blue line stream, or as determined by Wake County Soil maps, or as may be determined by local studies and documentation. Desirable artificial stream bank or shoreline stabilization is permitted. B. Protection of Buffers . No new development or expansion is allowed in the buffer except for water dependent structures and public projects such as road crossing, greenways and sewer and water utility lines where no practical alternative exists. These activities should minimize built-upon surface area, direct run-off away from the surface waters and maximize the utilization of stormwater best management practices ( BMPs). (5) Rules Governing the Interpretation of Watershed Area Boundaries . Where uncertainty exists as to the interpretation of the boundaries of the watershed areas, as shown on the watershed map, the following rules shall apply: A. Visual Boundaries . Where area boundaries are indicated as approximately following streets, alleys, railroad or highway centerlines thereof, such lines shall be construed to be said boundaries of the watershed area. B. Lot Line or Surveyed Line . Where area boundaries are indicated as approximately following lot lines, such lot lines shall be construed to be said boundaries of the watershed area. However, a surveyed plat prepared by a registered land surveyor may be submitted to the Town as evidence that one (1) or more properties along these boundaries do not lie within the watershed area.
