runoff limits technical committee

Stormwater runoff from impervious surfaces is perhaps the greatest threat to imperiled fishes in the Etowah basin in Georgia. The HCP Runoff Limits program requires that in the most sensitive watersheds, the volume of runoff from new development must match that of the site in an undeveloped, forested condition. For moderately sensitive watersheds and designated development nodes, the runoff limits are higher. The limits are based on studies of sensitive fish tolerances and the distributions of imperiled fish species in the Etowah, and are intended to provide assurance that development impacts will not exceed the thresholds that these species can tolerate. Although the program will compel significant changes in stormwater management practices in the basin-including widespread use of infiltration-its performance standards are straightforward and only simple engineering calculations are required. It is being supported by development of a design manual and training program.
