Lake Berryessa East Side Road Seeding

The Department of the Interior Bureau of Reclamation is preparing to procure no-till native seeding services for approximately 383.8 acres at Lake Berryessa near Napa, California, with a sources-sought response due June 24, 2026. No set-aside applies. The Bureau is concurrently issuing a Request for Information (RFI) to gather market feedback and contractor capability data before releasing a formal solicitation.

Work is classified under NAICS 115112 (Soil Preparation, Planting, and Cultivating). Place of performance is the Lake Berryessa Field Office near Napa, California, with staging at the Eticuera Day Use Area. The contractor must provide all labor, supervision, native seed, equipment, tools, and materials to seed five paddocks along East Side Road using 100% native grass and wildflower seed containing a minimum of five government-approved species (including California Barley, Purple Needlegrass, Blue Wildrye, and Small Fescue). Seeding must occur during October–November only unless written authorization is obtained, with performance windows October 1–November 30, 2026 (base) and October 1–November 30, 2027 (option). Seeding must achieve within 3% of acreage with even distribution per native grassland restoration standards.

Contractors must conduct pre-construction biological surveys for California Red-legged Frog and Keck's checker-mallow within 14 days prior to work start, implement Worker Environmental Awareness Training, enforce a 10 mile-per-hour speed limit, prohibit work during or within 24 hours following rain of 0.5 inches or more, and fully decontaminate equipment and vehicles before site arrival. The contract will be firm-fixed price with separate option-year CLINs for individual paddocks determined by government monitoring results. Deliverables include biological survey reports, seed procurement documentation, work plan, quality control plan, and a final completion report due within 30 days of annual seeding completion. Responses to the RFI should address business information, capability statement, relevant project history (last five years), and feedback on the attached draft Performance Work Statement.
