The City’s Bureau of Environmental Services has published an updated Stormwater Management Manual. The manual creates a guideline to help manage stormwater at development and improvement project sites in our community.
Previously updated in 2008, the manual teaches developers and property owners how to reduce the effects of stormwater runoff to help protect watershed health, water quality in rivers and streams, and groundwater as a drinking water source.
Stormwater management tools can include landscaped swales, stormwater planters, vegetative filters, and landscape or underground infiltration.
Thanks to Portland’s robust environmental programs and investments in our sewer infrastructure, our local waterways are cleaner and safer for people and fish.
The 2014 Stormwater Management Manual is available online: www.portlandoregon.gov/bes/SWMM. Free CDs with the manual are available at the Development Services Center (1900 SW 4th Avenue) or by calling (503) 823-7103.
