Post-Construction Stormwater Management

WWE’s work on stormwater quality management has earned the firm a national reputation in this area of our practice. As one of the co-developers of the International Stormwater Best Management Practices (BMP) Database, WWE has assisted with compiling and analyzing data for more than 750 BMP monitoring sites across the country. This has given us excellent familiarity with performance expectations for different types of BMPs and insight into design details that can contribute to the success or failure of a stormwater quality management project.

WWE has led the way with Green Infrastructure (GI) Low Impact Development (LID) in the mountain west, working with the Mile High Flood District on criteria for our climate, monitoring innovative practices around the Denver metropolitan area and nationally, and continually networking with colleagues around the country to stay on the cutting edge of stormwater treatment practices. While passive treatment technologies (BMPs, LID, and GI) are suitable for stormwater quality treatment on many sites, in some cases, numeric stormwater discharge standards may apply (in particular for industrial sites). In these cases, WWE has extensive expertise in evaluating both passive and active treatment systems to achieve permit compliance.

Construction Stormwater Management

The key to the management of stormwater from construction sites is the minimization of erosion and offsite sediment transport. WWE has a long history in erosion and sediment control; we were advising clients on ways to minimize excess erosion and manage sediments from construction activities long before there were widespread regulatory requirements to do so.

Now there are federal, state, and local regulations requiring detailed construction-phase stormwater plans for sites disturbing one acre or more (and for some smaller sites near waterways). WWE’s multiple Certified Professionals in Erosion and Sediment Control (CPESCs)—some of whom are also P.E.s, along with many of our other staff who are geologists, soil scientists, engineers, and aquatic life scientists—are able to address clients’ construction-phase needs ranging from small utility projects to large-scale land development activities.

WWE has national and international experience dealing with erosion issues and has developed hundreds of Stormwater Management Plans (SWMPs) for construction activities, Stormwater Pollution Prevention Plans (SWPPPs) and Grading, Erosion and Sediment Control Plans (GESCs). All of these plans outline the best management practices (BMPs) to minimize the potential for adverse impacts to water quality during construction.

WWE assists new clients who have received a Notice of Violation (NOV) and helps existing clients to avoid NOVs.

Industrial Stormwater Management

WWE has experience working with a broad range of industry types, assisting clients with stormwater management and compliance at both small and large facilities. Our projects range from assisting family-owned industrial businesses with industrial stormwater permit requirements to advising large multi-national corporations on options for advanced stormwater treatment.

WWE CEO Jon Jones has served as an advisor to the EPA on a variety of stormwater management issues, including Jon’s review of the draft version of the EPA document Wet Weather Research Plan and Stormwater Pollution Prevention for Industrial Activities (1996). He is now serving on an expert panel addressing stormwater management and treatment issues at the Santa Susana Field Laboratory, a former rocket-testing facility located outside of Los Angeles.

Other industrial stormwater clients include U.S. Department of Energy facilities, ExxonMobil, Arch Coal Company, Boeing, and the Coors Brewing Company.
