Emerging Water Quality Treatment and Flow Control Performance -- Trends for Low Impact Development Practices

Abstract

Curtis Hinman will discuss the problem of urban pollutants and stormwater conditions affecting water quality treatment in the Puget Sound and surrounding watersheds. Structural stormwater controls alone have limitations for protecting native characteristics of streams, lakes, wetlands, and Puget Sound. Hinman will present emerging trends in Low Impact Design (LID) flow control and water quality treatment performance: 1. Residential LID pilot flow control performance. Case studies will be presented and results described. 2. Pervious pavement flow control and water quality performance. Case studies will illustrate pervious pavement outcomes. 3. LID data gaps and future research.
