Abstract
Storm Drain System Inventory for NPDES Permit Compliance
Track: Water Distribution, Wastewater, and Stormwater
Author(s): Douglas Brice, Heather Kelley
The California Department of Transportation (Caltrans), in order to meet the requirements of the Clean Water Act and the nine state Regional Water Quality Control Boards (RWQCBs), enlisted Burns & McDonnell to field inventory all stormwater features contained within Caltrans property for Districts 4 and 12. Stormwater inlets, outfalls, discharge points, drainage areas, and facilities (i.e., maintenance stations, park and rides, etc.) were inventoried using a combination of submeter GPS units, pen-based computers, laser range finders, and digital cameras. The project serves as a tool for the National Pollution Discharge Elimination System (NPDES) permit compliance process. The project encompassed 900 highway miles in the San Francisco Bay Area as well as 310 miles in Orange County (Southern California). The accumulated data set gives Caltrans engineers a clear vision of existing storm water features and allows them to identify sites where best management practices (BMP) could be employed.
