Stream Maintenance Work to Commence in
Santa Rosa Creek, Prince Memorial Greenway

North side of Santa Rosa Creek Trail to be closed September 13 – October 1

(Santa Rosa, CA)  Sonoma County Water Agency work crews on September 13 will begin stream maintenance work in Santa Rosa Creek between Santa Rosa Avenue and Olive Street.  The work will include selectively thinning and removing non-native and invasive vegetation, and pruning native vegetation such as alders.  The maintenance work will improve creek conditions, habitat and flood protection in and around Santa Rosa Creek.  Work is expected to be completed by October 1.  The goal of the Stream Maintenance Program is to maintain flow conveyance within flood control channels and streams while protecting the environment by establishing mature, native vegetation. 

To ensure public safety and secure maintenance equipment, the north side of Santa Rosa Creek Trail will be closed between 8a.m. and 4p.m. during maintenance work. A detour to the path immediately south of Santa Rosa Creek will be implemented for continued access to the trail system. 

“It is our goal to keep streams both vibrant for wildlife while ensuring they continue to provide their vital flood protection role,” said Water Agency Stream Maintenance Coordinator Jon Niehaus. “The public is urged to keep clear of maintenance work and equipment as a safety precaution.”

By promoting and planting native vegetation, shaded canopies are created that help cool the water and shade out less desirable species of plants, which can catch debris and reduce the water carrying capacity of streams. Water Agency biologists and arborists survey maintenance sites for nesting birds and oversee vegetation removal activities.

The Water Agency performs maintenance on more than 80 miles of engineered flood protection channels countywide and is diligently working to complete its list of scheduled maintenance by mid-October; before the rainy season begins.  For a complete list of streams to be maintained this year, visit
