The Evolution of Stormwater Management
In September, the New York City Department of Environmental Protection (DEP), in partnership with the Water Research Foundation, released Innovative & Integrated Stormwater Management, an examination of stormwater programs from around the globe (DEP 2017). To develop the most effective stormwater management program possible, DEP looked to its peers in other municipalities to understand which methods have been successful in implementing stormwater management programs and meeting regulatory requirements. Service providers can use the information in the report to cost-effectively improve the health of local waterbodies and deliver related benefits to their communities.
Over 34 communities participated in this project, providing details on their experiences with National Pollutant Discharge Elimination System Municipal Separate Storm Sewer Systems (NPDES MS4) permit compliance, Consent Decree compliance, flood reduction programs, and other integrated stormwater management initiatives. Insights from this report will inform the future development of DEP’s programs and initiatives as the city strives to proactively manage stormwater and wastewater in a more holistic manner.
The report topics encompass the U.S. Environmental Protection Agency (EPA)-recommended NPDES MS4 requirements and additional requirements commonly found within NPDES MS4 permits. Additional topics that are critical to stormwater program success, or those that can result in progressive and innovative water quality solutions, are also covered in the report. The specific report topics include:
• Innovative stormwater planning, policy, and regulations
• Public involvement and education programs
• Illicit discharge detection and elimination programs
• Construction and post-construction stormwater management programs
• Municipal facilities pollution prevention programs
• Industrial and commercial stormwater management programs
• Floatables and street litter reduction programs
• Structural stormwater controls
• Stormwater monitoring
• Funding sources and financial incentive programs.
Case studies are presented for communities with progressive programs in each topic area.
