Funded through the Washington State Department of Natural Resources, the Puget Sound Urban Tree Canopy and Stormwater Management Handbook provides an overview of both the general and stormwater reduction benefits of urban tree canopy. The goal of the handbook is to promote tree planting and tree retention as a green stormwater infrastructure strategy.  The intent is to encourage dialogue between urban forestry and stormwater management professionals and support engagement among these groups with policymakers and implementers, builders and developers, and property owners to achieve this goal.
