Meins Landing Levee Improvement Project Geotechnical Investigation

The California Department of Water Resources is advancing the Meins Landing Levee Improvement Project with a geotechnical investigation using hand augers at a site one mile west of Birds Landing in Solano County, bounded by County Road No. 249 and Montezuma Slough. This pre-design activity, scheduled for August 2025, involves drilling up to 51 geobore holes to collect subsurface data critical for engineering design, including the construction of a setback levee and restoration of 52 acres of tidal marsh habitat. The project is being managed under the California Environmental Quality Act (CEQA), with a Class 6 Categorical Exemption applied to the hand augering work, and requires full compliance with state historic preservation protocols through the use of DPR 523A/B forms to document and evaluate cultural resources such as historic levee segments and parallel ditches. Historical significance is assessed against the California Register of Historical Resources Criteria 1 through 4, while mitigation measures mandate immediate work stoppage and consultation with the Native American Heritage Commission if human remains or culturally significant artifacts are encountered. The procurement is listed as a forecast with no formal solicitation number, contract value, or pricing details available, and no federal acquisition regulation clauses or standard contract provisions have been incorporated. The only recognized attachments are the DPR 523 cultural resource inventory forms, which include location data, photographs, and historical condition assessments. Inspection and acceptance are conducted by the California Department of Water Resources at the project site, ensuring compliance with CEQA guidelines and state cultural resource procedures rather than federal technical or quality standards. There are no specified contract types, payment offices, invoicing methods, or contracting officer roles identified, and no socioeconomic, small business, or entity certifications are required or provided. Submissions must include a Notice of Exemption, cover letter, site map, and Cultural Resources Technical Memorandum, to be delivered physically to the Office of Land Use and Climate Innovation in Sacramento or the Solano County Clerk of the Board in Fairfield, though no submission deadline or electronic filing system is stated. The contract remains in a planning and data-gathering phase, with no firm performance period, delivery schedule, or financial obligation yet established.
