Using Low-impact Development Strategies to Mitigate Heat Island Effect in Receiving Waters

Abstract

Stormwater temperature is an essential but overlooked aspect of the urban stormwater condition. As urbanization occurs, the surrounding environment’s surface, air, and water are altered. Heated stormwater runoff flows across the hardscape into receiving waters and potentially increases the base temperature of surface water in lakes, streams, bays, and estuaries. The amount of heat transferred, and the degree of thermal pollution is of great environmental importance. The main purpose of this research is to develop design models for standard stormwater control measures that can be used to mitigate heat island effects and maintain the required thermal temperature in a receiving stream. This project engages controlled laboratory tests to assess low-impact development (LID) stormwater control measures to reduce the thermal impact of stormwater runoff. This project hypothesizes that pervious surfaces and rain gardens/bioretention can be used to mitigate thermal temperatures in stormwater runoff.
