Help Prevent Flooding in Portland

Help Prevent Flooding in Portland

During periods of excessive rainfall, snow, and ice melt, many areas of the City of Portland face a higher risk for flooding. To help prevent localized flooding, the Bureau of Development Services is recommending that storm drains are cleared to allow for sufficient erosion control or water drainage.

  1. Property owners should make sure the storm drains in front of their property are cleared and functioning to help avoid flooding. If a property you own or manage has surrounding storm drains, please ensure that those drains are clear.
  2. Contractors at construction sites should check the storm drains in the right-of-way frequently. BDS expects that the contractors with permits will inspect and maintain the site, and ensure that erosion control measures are in place and functioning. In situations where there is a potential for flooding, the contractor can remove the erosion control. The contractor is still responsible for offsite discharges.

For more information on stormwater drainage and tips on how to keep storm drains clean, visit the Portland Bureau of Transportation website.
