This is a Geotechnical Data Report supporting the USACE Sacramento District's Natomas Reach I Contract 2 (RIC2) design-bid-build construction project. The report provides subsurface investigation findings and geotechnical analysis for slope flattening work along the American River levee system in Sacramento, California, covering approximately 2.18 miles of landside slope from Gateway Oaks Drive to Northgate Boulevard and along the NEMDC.

The project involves excavation and reuse of approximately 15,000 cubic yards of levee embankment fill from on-site sources, supplemented by import of approximately 12,000 cubic yards of borrow fill. Work scope includes site preparation, utility relocation, construction of a 12-foot maintenance road at the landside toe, and tree removal. The estimated contract value ranges from $10,000,000 to $13,000,000 with a firm-fixed price structure. This total small business set-aside solicitation is being issued through PIEE and SAM.gov, with levee-impact activities restricted to the window between April 15 and November 1. The NAICS code 237990 (Other Heavy and Civil Engineering Construction) applies with a small business size standard of $45,500,000 annual revenue, and the PSC code is Y1LC (Construction of Tunnels and Subsurface Structures).
