Notice of Intent to Adopt a Mitigated Negative Declaration
Environmental Assessment/Initial Study for Delta-Mendota Canal Subsidence Correction Project
A joint Environmental Assessment (EA)/ Initial Study (IS) is being prepared by the San Luis & Delta-Mendota Water Authority (SLDMWA) and the United States Bureau of Reclamation. SLDMWA is the Lead Agency under the California Environmental Quality Act (CEQA) and Reclamation is the Lead Agency under the National Environmental Policy Act (NEPA).
The San Luis & Delta-Mendota Water Authority has released for a 30-day public review under CEQA: a draft EA/IS and a draft Mitigated Negative Declaration (MND) on the effects of the proposed subsidence correction project to restore the Delta-Mendota Canal (DMC) to its originally authorized conveyance capacity. The proposed project analyzed in this EA/IS would raise currently deficient canal lining, embankment, and other impacted structures to allow the DMC to convey its originally authorized capacity while satisfying current Bureau of Reclamation safety standards. Proposed project effects would occur within Alameda, San Joaquin, Stanislaus, Merced, Fresno, San Benito, and Santa Clara counties.
The documents are available for review at https://sldmwa.org/dmc-subsidence-project. Please contact Mr. Jacob Bejarano at (209) 832-6200, if you encounter difficulty accessing the documents or would like to request a CD copy. Written comments on the draft environmental document should be received by close of business March 14, 2023, and should be sent to:
Mr. Pablo Arroyave,
San Luis & Delta-Mendota Water Authority
P.O. Box 2157, Los Banos, CA 93635
or emailed to pablo.arroyave@sldmwa.org.
