Post Construction Runoff Control/Land Development Provisions
WHY IS THIS IMPORTANT?

The process of developing land into subdivisions, shopping centers, or office parks typically has a tremendous impact upon the quality of streams in the vicinity of the development both during and after the construction phase. Every time rain falls on a development, it washes off oils, bacteria, litter, sediment, fertilizers, and chemicals from streets, parking lots, lawns, dumpster pads, and metal roofs. Knowledgeable design of developments can solve the problem of contaminated runoff at the source. Georgia’s local governments can guide their new development to meet these concerns.


Some examples of land development provisions that can be made to protect Georgia water quality include density and infill zoning, limiting the amount of impervious surfaces in parking lots, roofs, streets, etc., limiting curbing of streets, incorporating vegetated swales, treatment of “hot spots” such as dumpster pads, providing biking and walking paths for non-automotive transportation alternatives, and using porous pavement materials. Many of these land development provisions can be adopted into community plans and implemented by modifying zoning ordinances.
