Delta Ecosystem Enhancement Programmatic Mitigation

The Delta Ecosystem Enhancement Section works hand-in-hand with the Department of Fish and Wildlife's Delta Levees Program and DWR's Delta Levees and Environmental Engineering Branch to develop cost-effective and environmentally superior habitat mitigation options for local agencies participating in the Delta Levees Program.

By taking a "Programmatic" approach to mitigation, the Program takes advantage of many possible mitigation opportunities for the participating local agencies. These can include purchasing existing credits from Delta bank sponsors, developing Program-owned mitigation sites to benefit all participating local agencies, and also allowing the local agencies to mitigate for their own needs on island or tract as appropriate.

As a result of the Bulk Acquisition of Mitigation Credit PSP, the Program now owns and is ready to resell to participating local agencies the following credits:


Mitigation Credit Description Quantity Unit Cost
Shaded Riverine Aquatic 4000 linear feet $61/lf
Riparian Forest (Floodplain Riparian Restored) 50 credits $62,295/Credit
Scrub-shrub (Floodplain Riparian Restored) 38 credits $62,295/Credit
Freshwater Marsh (Floodplain Mosaic Wetlands Restored) 2.5 credits $120,000/Credit

Details on the steps required to purchase credits through the Bulk Credit Program can be viewed in the letter (PDF, 556KB) to the local agencies from the Delta Levees Program dated December 5, 2012. Participating local agencies will be notifying RD 830, Jersey Island, as well as contacting Westervelt Ecological Services at (916) 646 – 3644 to initiate the purchase of credits through the program.

The Delta Ecosystem Enhancement Section's Role in Habitat Mitigation

Through the Delta Levees Program, DWR provides financial assistance to local reclamation districts in the Sacramento -San Joaquin River Delta for levee maintenance and repair. All habitat impacts associated with levee improvements must be mitigated. AB 360 specifies four main habitat types. Mitigation for levee improvement impacts requires the creation of terrestrial or freshwater habitats.

With the recent increase in Delta levee improvements due to funds provided through Propositions 1E and 84 and the time-sensitive nature of these improvements for the purposes of public safety, the Delta Ecosystem Enhancement Section seeks to proactively address mitigation requirements in advance of actual construction of the levee improvements (i.e., address mitigation needs in a programmatic fashion, rather than on a project-by-project basis).

The Bulk Acquisistion of Mitigation Credits

The Department of Water Resources, Delta Levees Program, released the final grant award for the Bulk Acquisition of Mitigation Credits application solicitation. Reclamation District 830, Jersey Island, has been awarded $6 million in grant funds for the purchase and resale of mitigation credits from the Cosumnes Floodplain Mitigation Bank to local agencies participating in the Delta Levees Program that require mitigation. Guidelines and description of enabling legislation (California Water Code, Sections 12300-12314) are available on the Delta Levees Special Projects webpage, at www.water.ca.gov/floodsafe/fessro/levees/special_projects/special_projects.cfm.

For more information about the bulk acquisition of mitigation credits, now known as the Bulk Credit Program, see the original Project Solicitation Package (PDF, 274KB), released in October 2011.
