Project Composition

52 Implementation Projects Total

  • 17 - IRWM Proposition 50 Round 1
  • 4 - IRWM Proposition 50 Round 2
  • 18 - IRWM Proposition 84 Round 1
  • 13 - IRWM Proposition 84 Round 2
  • Total project cost: $80,544,371, spent locally using local supplies and services when possible

Project Type

  • 24 water/wastewater infrastructure projects (46%)
  • 43 water quality improvement projects (81%) – both instream water quality improvement and drinking water quality improvement projects
  • 24 water supply reliability projects (46%)
  • Note: several projects provided multiple benefits – both water quality and supply reliability benefits

Quantitative Benefits

Water Supply and Water Quality

  • 20 projects enhance instream flows by a conservative estimate of 1,908,326 gallons of water per day
  • 37 (71%) projects assist with TMDL implementation by decreasing sediment, nutrient, or pathogen loads or through increases to instream flows, helping to ameliorate increased water temperatures during summer months
  • 24 sediment reduction projects remove and/or stabilize over 910,945 cubic yards of sediment
  • Miles of road decommissioned – 78.56; 103.81 miles of road upgraded
  • Four projects avoid wastewater violations fines and penalties

Salmonid Habitat 

  • 38 projects (73%) protect or enhance North Coast coho, Chinook, and/or steelhead fisheries
  • 11 projects improve fish passage by opening at least 156.46 miles of instream habitat for spawning and rearing
  • 24 projects have habitat restoration components:
    • Install at least 64,947 native trees, shrubs, and grasses
    • Restore over 838 acres or riparian or wetland habitat
    • Restore/ enhance at least 91,256 linear feet (17.28 miles) of riparian habitat
  • 10 projects include invasive non-native plant removal; these projects collectively remove invasive plants from at least 514.20 acres
  • Ten projects have in place ongoing monitoring and data evaluation programs


  • 24 projects protect the agricultural and resource-dependent heritage of farmers, ranchers, Tribes, and other residents of the North Coast
  • 11 projects provide for social health and safety by improving access for emergency vehicles, improving impacted drinking water quality in econmically disadvantaged communities, and protecting public health through contaminant reduction
  • 52 (all) projects used local labor and supplies when possible and contribute to state goals for environmental justice and social equity

Content was developed from information provided by project proponents in reports, contracts, grant proposals, with research and analysis by ECONorthwest, an economics consulting firm. Consistent with widely accepted professional standards, ECONorthwest considered a broad suite of goods and services including those whose value comes from indirect or non‐use of resources. Where sufficient detail exists, project sponsors’ estimates of expected or realized benefits were used.
