Delta Levees Program Habitat Banking

The Delta Levees Program, encompassing 1,100 miles of levees, aims to protect local land uses and regional infrastructure while addressing salinity intrusion. With historical flooding challenges and significant habitat impacts—such as freshwater marshes and riparian forests—the program is guided by legislative mandates requiring no net loss of habitat. Collaborative partnerships with Reclamation Districts, DFG, and DWR enhance funding for habitat banking, focusing on regional conservation. Key challenges include strategic site selection and funding management solutions to ensure enduring habitat protection.

  1. Delta Levees Program Habitat Banking

  2. 1100 miles of levees in Delta

  3. Protecting local land use

  4. Protecting regional infrastructure

  5. Reducing salinity intrusion Max Intrusion 1921-1943 Max Intrusion 1944-1990

  6. Many areas now below sea level

  7. Most areas have flooded at least onceHistorical breaches since 1900

  8. Major habitats affected by levee projects • Freshwater Marsh • Scrub-Shrub • Riparian Forest • Shaded Riverine Aquatic

  9. Legislature requires habitat protection 1988 - No net loss of habitat (SB34) 1995 - Net long-term improvement (AB360)

  10. Delta Levee ProgramCollaborative Partnership Reclamation Districts Delta Levees Program DFG DWR

  11. Increased concern and visibility

  12. Increased levee funding

  13. Habitat banking • Pool mitigation from multiple projects • Regional – bigger picture • Advanced – before impacts

  14. Similar to other approaches • Mitigation and conservation banking • For jurisdictional wetlands, T&E • Regional conservation plans (HCP/NCCP) • Regional analysis and mitigation • Mostly private development driven

  15. Several key challenges • Selecting strategic locations • Coordinating with other efforts • Funding habitat before impacts • Funding perpetual management

  16. Coordination with others • Bay Delta Conservation Plan • 5 NCCP/HCPs • Ecosystem Restoration Program • 4-Pumps Agreement • OCAP – State Water Project env’l permitting • others

  17. Several key challenges • Selecting strategic locations • Coordinating with other efforts • Funding habitat before impacts • Funding perpetual management

  18. Banking options • Existing commercial habitat banks • DWR-sponsored bank or local levee-district bank • Customized commercial bank
