Wetland Riparian Area Protection Policy
Clean Water Act Section 401 – Certification and Wetlands Program
State Wetland Definition and Procedures for Discharges of Dredged or Fill Material to Waters of the State
The State Water Resources Control Board (State Water Board) adopted a State Wetland Definition and Procedures for Discharges of Dredged or Fill Material to Waters of the State (Procedures), for inclusion in the forthcoming Water Quality Control Plan for Inland Surface Waters and Enclosed Bays and Estuaries and Ocean Waters of California. The Procedures consist of four major elements: 1) a wetland definition; 2) a framework for determining if a feature that meets the wetland definition is a water of the state; 3) wetland delineation procedures; and 4) procedures for the submittal, review and approval of applications for Water Quality Certifications and Waste Discharge Requirements for dredge or fill activities.
The State Water Board adopted the Procedures to address several important issues. There is need to strengthen protection of waters of the state that are no longer protected under the Clean Water Act (CWA) due to U.S. Supreme Court decisions, since the Water Boards have historically relied on CWA protections in dredged or fill discharge permitting practices. Second, there is inconsistency across the Water Boards in requirements for discharges of dredged or fill material into waters of the state, including wetlands. There is no single accepted definition of wetlands at the state level, and the Water Boards may have different requirements and levels of analysis with regard to the issuance of water quality certifications. Finally, current regulations have not been adequate to prevent losses in the quantity and quality of wetlands in California, where there have been especially profound historical losses of wetlands.
The Procedures, formerly known as the Wetland Riparian Area Protection Policy, has been renamed in order to communicate that the Procedures apply to all discharges of dredged or fill material to waters of the state, not just wetlands.
The Office of Administrative Law (OAL) approved the Procedures on August 28, 2019. Pursuant to the Procedures, the effective date is nine months upon OAL approval. Accordingly, the Procedures will be effective May 28, 2020.
The State Water Resources Control Board issued a Notice of Decision on August 30, 2019.

- Board Presentation (PPT)
- 2007 April-May - Wetland and Riparian Area Protection Proposed Policy
- Executive Order W-59-93 (signed by Governor Pete Wilson on August 23, 1993) established state policy guidelines for wetlands conservation. The primary goal of this policy is to ensure no overall net loss and to achieve a long-term net gain in the quantity, quality, and permanence of wetland acreage in California. The federal wetlands policy, representing a significant advance in wetlands protection, was unveiled by nine federal agencies on August 24, 1993.
- Compensatory Mitigation Study Now Available
The State Water Resources Control Board has released a comprehensive study that evaluates the effectiveness of the State's wetland regulatory program. The study found that the permit compliance was generally met and that overall wetland acreage was being maintained; however, the biological health of the these replacement wetlands was low. The study is titled "An Evaluation of Compensatory Mitigation Projects Permitted Under Clean Water Act Section 401 by the California State Water Resources Control Board, 1991-2002" by Richard F. Ambrose and Steven F. Lee of the University of California, Los Angeles, and John C. Callaway of the University of San Francisco.
