Department of Water Resources Urban Streams Restoration Program Working Together To: • Restore Watersheds • Reduce Property Damages • Renovate Town Centers
Traditional Stream Management • Historically delegated to single purpose agencies with specific goals (i.e. flood control, water conveyance, mosquito abatement, minimizing creek corridor to maximize development). • Ecosystem health generally a priority only in park areas.
Limitations of Single Purpose Flood Control Projects • High costs • Long timeframes • Maintenance costs • Little regard for environmental quality • Possible violation of environmental laws • Unsafe during high water events • Potential fragmentation of communities
USRP Program Background • Created in response to limitations of single-purpose flood control projects and traditional stream management practices • Enabling legislation: Urban Creek Restoration and Flood Control Act of 1985 • Authorized DWR to make grants and provide technical assistance to local governments and organizations for multi-objective projects
Program Objectives • Assist communities in reducing damages from stream bank and watershed instability and floods • Restore environmental and aesthetic values of streams • Encourage stewardship and maintenance of streams by the community
Potential Benefits of Urban Stream Restoration • Reduce flood damage and erosion • Re-establish fish and wildlife habitat • Improve water quality • Increase groundwater recharge • Provide educational/recreational opportunities • Provide focal point for urban revitalization • Encourage community stewardship
Projects Funded by USRP • Creek cleanups • Bioengineering bank stabilization • Vegetation management • Channel reconfiguration to improve geomorphology • Land/right of way purchases • Daylighting
Case Studies • Dry Creek, Roseville • Fresno River, Oakhurst • Poinsett Park, El Cerrito
Dry Creek, Roseville • 2-phase project consisting of an erosion assessment/management plan and restoration • Channel reconfiguration, bank stabilization and revegetation at three key sites • Improved fish passage • Collaborative effort between the City of Roseville and the Dry Creek Conservancy
After Darling Way Site Before
Fish Passage Improvement • Adelante • Spawning gravels and resting habitat • Downstream of Darling Way site • Easier migration access – modifications to banks and stream around sewer line
Fish PassageBefore and After After Before
Fresno River, Oak/China Creeks, Oakhurst • Project Background • Rural foothills community near Yosemite • Development around waterways destabilized banks and increased flood damage to surrounding homes and businesses • Oakhurst River Parkway Committee formed to address issues • Funding and restoration activities pursued in a community-wide effort, with assistance from multiple agencies, businesses, and citizens
Project Activities • stream restoration • erosion control • trail system stabilization • creek clean-ups • vegetation management • community education
Poinsett Park, Project Background • City’s storm drain system inadequate, resulting in localized flooding • City commissioned study to evaluate pipe conditions and develop master plan of corrections • Local residents approved $6.3 million bond to finance repairs • City chose stream restoration alternative over pipe repairs in some locations • Short-term increased costs for restoration, but long-term decreased costs for pipe repairs • DWR grant was to finance a demo “daylighting” project at Poinsett Park for the restoration alternative
