Stormwater Management

If you know that your project will add more than 500 square feet of new and/or redeveloped impervious area (such as paving or new roof area) then we suggest that you contact staff from the Bureau of Environmental Services to discuss your options for dealing with the stormwater discharge. This advice also applies if your project would change the way stormwater is currently discharged off the site. You can reach BES staff at (503) 823-7761.
