Swale Demonstration Project

 

WSU Spokane County Extension and Spokane County Stormwater Utility are conducting a demonstration project involving bio-infiltration swales.  Twelve swales in Spokane County were selected for the project. All of the swales are located in residential front yards, and all property owners agreed to participate in the project by allowing their swale to be excavated, refilled with an engineered soil mix, and then planted with either turfgrass or alternative plants.

 

The project team hopes that this demonstration project contributes to our technical understanding of swales, raises awareness of their value in protecting our water quality, and tests the viability and effectiveness of alternative plants versus turfgrass in swales.
