Novato Creek WatershedUpper Watershed Restoration Opportunities
Anatomy of a Watershed Headwaters Valley Floor Estuary Riparian Forest Bay
Major Novato Creek tributaries • Novato Creek- • Bowman Canyon • Vineyard-Warner • Wilson • Arroyo Avichi • Cheda Creek • Arroyo San Jose • Pacheco Creek
Upper watershed land use is primarily agriculture and open space Bowman Canyon
Valley floor land use is primarily residential with scattered park lands
Beneficial Uses Water Quality Water Supply Wetlands Wildlife Protection Recreation Agriculture
Hamilton and BMK 5 Restoration Total Project Conceptual Design • Scan pdf 2600 Acres
Flood History • Significant flooding in 1955,1982, 1983 1986, 1995, 1998, 2005-06

Novato Creek-late 1880’s • Novato Creek has been navigable since the mid 1870’s when 23 ton schooners made weekly trips to San Francisco “California • Tidal influence extended through and upstream of Nave Shopping Center • In 1880 the creek was dredged to keep the wharf open “Solferno”
Tidal marshlands and sloughs were diked and drained for agriculture around the 1860's
Geomorphic Channel RestorationDesign Considerations • Maintain Active Channel Width • Consider Both Banks • Consider Upstream & Downstream Effects • Retain Native Vegetation • Moderate to Gradual Bank Slope • Incorporate Native Vegetation into Design • Invasive Species Have Poor Rooting Strength-Replace with Native Plants
Biotechnical Bank StabilizationIncorporating Native Plants into the design process
Creek Wildlife • Salt Marsh Harvest Mouse • River Otter • Muskrat • Blue Heron • Clapper Rail • Jack Rabbit • Songbirds

Friends Of Novato Creek Introduction Background, Challenges and Opportunities
Friends of Novato Creek Watershed • Founded as a 501c3 Non Profit Corporation in 2001 – Received ruling 2006 • Members of the local communities, FNC members are teachers, engineers, contractors, students, lawyers, biologists, business owners . • Monthly meetings, semi annual trainings and events, including storm drain painting , creek cleanups, invasive species removals, water monitoring and creek walks.
FNC Mission • Organized for the protection, restoration, and improvement of the Novato Creek Watershed. • To build community awareness through programs in partnership with the local community
Public Outreach & Education Signage Creek Cleanups Citizen Water Monitoring Educational Programs Research Projects Riparian Restoration FNC Programs:
Historic Monitoring & Data Citizen Water Quality Monitoring Concerns- pesticides, sediment, pathogens Water Quality
Novato Creek Invasive weeds • Himalayan Blackberry • Giant Reed • Ivy (German, English, Cape) • Pepper weed
Citizen Monitoring – Benthic Macroinvertebrates • FNC has trained 15 volunteers / Conducted 2 trainings • 2006 - conducted monitoring of 5 sites including water quality, BMI collection, and physical habitat • Data pending
Benthic Macroinvertebrate Monitoring Data Collection
FNC-Next Steps • Increase efforts to build awareness of the watershed (literature / sign projects • Presentations in local schools and work with local youth organizations • Work with Marin County & City of Novato • Continue to develop water monitoring program
Novato Creek Challenges • Flooding • Water Quality • Channel management • Habitat, sensitive species, and fisheries • Bank erosion and stream stability • Illegal camp sites • Groundwater • Invasive weeds • Invasive species-partnered w/ Romberg Tiburon Ctr to monitor Harris Mud Crab
Novato Watershed Planning Documents • City of Novato General Plan • Draft Marin Countywide Plan & Watershed Management Plan • NBWA Watershed Stewardship Plan and IRWMP • Marin County Flood Control and Water Conservation District-Technical Studies • San Francisco Bay Watershed Plan • State of CA Basin Plan-TMDLs & 303d listings • Phase II NPDES Storm Water Permit and MCSTOPPP stormwater management plan
