The Stream Restoration Program’s objective is to create a stable stream system that decreases property loss from erosion and increases the beneficial uses of our waterways.

The Stream Restoration Program utilizes stream stabilization techniques such as reinforced earth bank reconstruction, limestone rock grade controls to stabilize the channel slope and rock weirs to capture sediments and redirect flows. Native materials and vegetation are used to the greatest extent possible to enhance the natural creek setting.

What is happening to our creeks?
Erosion is part of a natural channel cycle, but in an urban environment the historical erosion rates spike due to the increase volume of stormwater runoff. In order to compensate for the additional stormwater volume, creeks get deeper and wider (channel enlargement) through erosion. As channels enlarge in an urban environment, residential and commercial property, bridges, roadways, and utilities are threatened.

History
The Stream Restoration Program was created in 1994 to provide stream erosion control services. The Watershed Protection Master Plan was completed in 2001. As part that effort, 17 watersheds were assessed for erosion problems and stream stability. The watershed erosion assessments identified localized erosion problems, unstable stream reaches and threatened structures.

Program Services
The Stream Restoration Program services include stream stability assessment (understanding the problem), planning (prioritizing problems and projects), solution development (in-house design or consultant services), implementation (in-house construction or capital projects) and technical assistance (sharing expertise and experience).
