This document summarizes a study on the cost-effectiveness of various stormwater management practices for reducing nitrogen, phosphorus, and total suspended solids in the Chesapeake Bay watershed. The study found that pet waste programs, sewer repair, and illicit discharge detection were among the most cost-effective practices for nitrogen and phosphorus reduction. Urban stream restoration and dry pond retrofitting were among the most cost-effective for reducing total suspended solids. Applying the study's findings to the City of Richmond, scenarios that incorporated more approved practices and city constraints had significantly lower estimated costs for meeting pollution reduction targets.
