GLRPPR Sector Resource: Accelerating Cost-Effective Green Stormwater Infrastructure: Learning from Local Implementation

Title:
Accelerating Cost-Effective Green Stormwater Infrastructure: Learning from Local Implementation

Abstract:
Ineffective stormwater management is a serious problem nationwide. Conventional strategies based around "gray" collection and conveyance systems--networks of gutters, storm drains, and sewers--have not solved persistent stormwater problems. Instead they have shifted, and in many cases exacerbated, the impacts of stormwater runoff, trading urban flooding for pollution and physical alteration of nearby rivers, streams, lakes, and estuaries. Communities searching for cost-effective solutions to their stormwater woes are increasingly recognizing the benefits of a more holistic management approach that employs a locally tailored mix of stormwater control measures, including green stormwater infrastructure (GSI). Well-implemented GSI keeps stormwater local. It works by infiltrating or evaporating precipitation where it falls or capturing it for later use. The goal is to minimize the quantity and maximize the quality of urban runoff that flows to local waters. GSI is a critical tool for solving stormwater management challenges. However, it is evolving technology with inconsistent performance and uncertain costs. Addressing knowledge gaps through enhanced learning from local implementation efforts would speed cost-effective deployment. The EPA and state water quality authorities are already beginning to require GSI for Clean Water Act compliance in some stormwater permits and combined sewer overflow (CSO) consent decrees. A natural extension would be to add or expand associated monitoring and reporting requirements. This report outlines key actions regulators can take to drive GSI information collection and sharing to accelerate cost-effective GSI deployment.
