As a condition of grant funding, the project must also provide ADA compliance and serve the public welfare. The project is almost entirely located within the NCDOT and Town of Waxhaw street rights -of -way. The right of way width is typically 60 feet but varies in some locations. For purposes of the permit, 60 feet will be used to compute the property area. Since the sidewalk runs with the roadway, the length of the sidewalk will be used to determine the area of the project and impervious area. The sidewalk will largely be built to match the existing grade and maintain existing swales and flow patterns. In some cases, offsite runoff enters the right of way, flows across the sidewalk and into the existing grass swale adjacent to the roadway. In other cases, the roadway runoff flows across the sidewalk and existing grassed shoulder by way of sheet flow. The runoff from the proposed sidewalks discharges to two main streams, an un-named tributary to Twelve Mile Creek and Rone Branch, both of which flow to Twelve Mile Creek in the Catawba River basin. The sidewalks grouped together geographically as Kensington Elementary sidewalks flow to the un-named tributary of Twelve Mile Creek. The sidewalks grouped together geographically as Waxhaw Elementary sidewalks flow to Rone Branch through multiple drainageways. Rone Branch discharges to Twelve Mile Creek. The drainage areas are computed from the USGS map at the most downstream point of proposed construction. Because space in the right of way is limited, existing drainage patterns are utilized as well as existing grassed swales and shoulders. There is little additional room to install water quality treatment trains or devices between the sidewalk (which is typically immediately inside the right of way) and the edge of the roadway pavement. For safety, the shoulder area is reserved for vehicle emergencies and to provide a separation between pedestrian sidewalk users and automobile traffic. It is also impractical to re- route flows for treatment due to the linear and limited nature of the right of way and adjacent property. The most practical method of water quality treatment is to utilize the existing grassed conveyance. -974'-)..i O/v ,;&7'1745L,h ®ENR North Carolina Department of Environment and Natural Resources Division of Water Quality Beverly Eaves Perdue Coleen H.
