Summary: Landing Page for the studies
(Site Construction to begin June 2024; Sampling August 2024-September 2024)
This effectiveness study will evaluate the infiltration ability and treatment efficacy of two non-vegetated bioretention cells. to 1) determine how the infiltration behaviors of non-vegetated cells change with respect to season and in the presence of deicer, and 2) determine if the pollutant removal efficiencies are impacted with respect to variable temperature, pollutant loading rates, and pollutant species across the seasons and in the presence of deicer. The objective of this study is to determine the effectiveness of a non-traditional approach to bioretention design that would be easier to maintain and less costly to install. The study is being performed cooperatively by the City of Spokane, the City of Spokane Valley, and Spokane County.
– NOTE: Ecology review of the QAPP is not complete; therefore, the final QAPP is not yet ready to be posted.
