Providing public involvement and educational opportunities Designing, constructing and maintaining stormwater quantity and quality facilities, and Implementation of Erosion Prevention and Sediment Control inspection and enforcement. Our goal is to clean all catch basins every year. The City has no dry wells or sumps. A sump is deep, perforated manholes, which collect run-off and debris. Your private drainage can take various routes before it reaches the public system.
Most properties drain to the curb.
The City is responsible for runoff from City streets. Private drainage responsibilities include keeping runoff from crossing neighbor's property, and directing the runoff to an approved discharge point. The City does have some mapping of private drainage systems. For the most part, these systems don't show on City drainage maps. Other times of the year, you can drop off materials at two sites in the Portland area.
