Sunset Weir and Pumps Fish Passage Geotechnical Investigations (Streambed Alteration Agreement EPIMS Notification No. SUT-58514-R2)

The California Department of Fish and Wildlife has authorized geotechnical investigations for the Sunset Weir and Pumps Fish Passage Project under Streambed Alteration Agreement EPIMS Notification No. SUT-58514-R2, issued to the Sutter Extension Water District pursuant to Section 1602 of the Fish and Game Code. The work involves two mud-rotary borings conducted over water at Paseo Road in Live Oak, California, to collect subsurface soil samples and Standard Penetration Test (SPT) data to inform the design of new pump station and intake structures following the planned removal of Sunset Weir. The borings will utilize casing advancers to stabilize boreholes below the water table and comply with ASTM D1586 for SPT sampling, using a 140-pound hammer to drive a split-spoon sampler 18 inches into the soil, with energy efficiency monitored to ensure data reliability. The project is exempt from CEQA review under Class 6 for information collection activities and is scoped to support hydraulic modeling and foundation design without altering the surrounding aquatic environment beyond what is necessary for data acquisition. No formal procurement contract or financial value is established, as this is a regulatory notification rather than a competitive procurement, and all work is conducted by the project applicant under oversight from CDFW. The effort is administratively managed by CDFW’s Region 2 – Northern Central office in Rancho Cordova, with Elaine Jeu designated as the primary point of contact for environmental compliance, while Lynn Phillips serves as the applicant’s representative. Although no contract clauses, payment details, delivery schedules, or evaluation criteria are specified, the activity is strictly limited to field investigations and sample collection consistent with state environmental and geotechnical standards. No packaging, labeling, shipping, or security requirements are imposed, and no socioeconomic certifications, UEI numbers, or contractual representations are required. The work location is clearly defined as Live Oak, CA 95953, with all technical outputs expected to be delivered at the site under government observation. The project does not involve competitive bidding, nor does it include option periods, key personnel designations, or special clauses beyond compliance with ASTM D1586 and Fish and Game Code Section 1602, reflecting its nature as a regulatory permit for non-disruptive data gathering in support of future infrastructure modifications.
