  1. Department of Water Resources Urban Streams Restoration Program Working Together To: • Restore Watersheds • Reduce Property Damages • Renovate Town Centers

  2. 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.

  3. 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

  4. 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

  5. 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

  6. 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

  7. Projects Funded by USRP • Creek cleanups • Bioengineering bank stabilization • Vegetation management • Channel reconfiguration to improve geomorphology • Land/right of way purchases • Daylighting

  8. Case Studies • Dry Creek, Roseville • Fresno River, Oakhurst • Poinsett Park, El Cerrito

  9. 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

  10. Project Location

  11. After Darling Way Site Before

  12. Adelante Site, Before

  13. Adelante Site, After

  14. 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

  15. Fish PassageBefore and After After Before

  16. Fresno River, Oak/China Creeks, Oakhurst

  17. 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

  18. Project Activities • stream restoration • erosion control • trail system stabilization • creek clean-ups • vegetation management • community education

  19. Before, ~1996 After, June 2000

  20. Poinsett Park, El Cerrito

  21. 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

  22. Before, 1995 After, 2000

  23. Healthy Streams, Vibrant Communities
