Phase 1 Environmental Site Assessments for the West Sacramento Levee Improvement Program

The West Sacramento Area Flood Control Agency (WSAFCA) seeks qualified firms to conduct Phase I Environmental Site Assessments (ESA) for parcels within the West Sacramento Levee Improvement Program. The work includes regulatory database searches, historical research, site walk‑overs, GIS data integration, risk screening, and preparation of draft and final ESA reports for each parcel. All activities must comply with ASTM E1527‑21, CERCLA, SARA, and applicable California statutes, and be supervised by a licensed professional geologist or engineer. The contract term is up to two years with a possible one‑year extension, and the contractor must manage multiple mobilizations across three project corridors (approximately 70 acres total). • Deliver separate Phase I ESA reports for each parcel (≈70 acres total). • Perform records review, historical research, interviews, and non‑intrusive site reconnaissance. • Provide GIS dataset compatible with ArcGIS and photographic documentation. • Identify Recognized Environmental Conditions and recommend Phase II investigations if needed. • Submit draft reports for review, incorporate comments, and deliver final reports. • Project management includes monthly progress updates, schedule and budget logs, and coordination with WSAFCA and the State Water Resources Department.
