Delta Ecosystem Enhancement
The Delta Ecosystem Enhancement Section is an interdisciplinary team of scientists, engineers, and land managers, who develop, enhance and maintain ecologically effective habitat through the following efforts:
Coordination of environmental compliance requirements for the Delta Levees Programs, including habitat mitigation;
Implementation of the Delta Levees Programs' ecosystem enhancement mandate; and
Coordination with other local, state and federal entities to improve habitat conditions in the Delta and Suisun Marsh.

- About Us
For more information about the policy framework in which the Delta Ecosystem Enhancement team works, see About Delta Ecosystem Enhancement.
Water Code 12314(c) states that Delta Levees Program projects will not result in a net long-term loss of riparian, fisheries, or wildlife habitat. For further information about significant habitat, see Delta Levee's Significant Habitat Types.
Past Projects - In the past, most local agency mitigation obligations have been met through individual on-island mitigation projects.
Bulk Credits - Delta Levees Program purchased mitigation credits from the Cosumnes Floodplain Mitigation Bank through Reclamation District 830 , Jersey Island, for purchase by participating local agencies.
Planning Efforts - Delta Ecosystem Enhancement and California Fish and Wildlife staff are looking to create a mitigation site specific to the Delta Levees Program
Delta Ecosystem Enhancement develops and implements a variety of projects providing habitat enhancement in the Delta and Suisun Marsh. For more information, see Delta Ecosystem Enhancement, Enhancement Projects.
