This Geotechnical Data Report (GDR), prepared by Kleinfelder, Inc. for the Sacramento Area Flood Control Agency (SAFCA), summarizes the preliminary geotechnical exploration and laboratory testing conducted at the Brookfield Site 2C in Sutter County, California. The purpose of the investigation was to evaluate the suitability of the site's subsurface soils for use as a borrow source for the United States Army Corps of Engineers (USACE) Natomas Basin Project levee improvement construction. The field investigation, completed between December 2022 and February 2023, involved advancing 32 hand auger explorations to depths of 5 to 10 feet below ground surface. Five of these locations were selected for geotechnical sampling and laboratory testing, which included moisture content, Atterberg limits, grain size analyses, and organic content evaluations. The subsurface conditions primarily consist of fat or lean clays, clayey/silty sands, and silts. Standing water was noted near the surface due to heavy storms. Soil samples were compared against USACE geotechnical levee criteria, which require at least 20 percent fines, a plasticity index (PI) between 8 and 40, and a liquid limit (LL) under 45. Test results indicated that some shallow soils (within the top foot) and isolated deeper intervals exceeded the maximum liquid limit or plasticity criteria. Consequently, Kleinfelder recommends stripping and stockpiling the top foot of soil. The underlying soils generally meet or can be blended to meet USACE specifications. Contractors must develop a detailed borrow plan and perform additional testing prior to utilizing the site.

This draft Technical Memorandum presents the results of a Soil and Site Investigation conducted by AECOM Technical Services, Inc. at the 145-acre Brookfield Borrow Site in Sutter County, California. Prepared for the US Army Corps of Engineers (USACE) under Contract W91238-21-D-0002, the investigation supports the Natomas Basin Project by evaluating the suitability of the site's subsurface materials for use as levee embankment fill. The investigation, performed in June 2023, built upon a preliminary December 2022 survey by Kleinfelder. AECOM excavated 15 test pits to depths of approximately 10 feet, collecting soil samples for geotechnical index testing and environmental chemical screening. Geotechnical evaluations included sieve and hydrometer analyses, Atterberg limits, triaxial shear, moisture-density relationships, and permeability testing. Environmental testing screened for metals, petroleum hydrocarbons, pesticides, herbicides, and volatile organic compounds. The site is underlain primarily by fine-grained Pleistocene alluvial deposits from the Riverbank and Modesto Formations, consisting of silts, lean clays, and fat clays, with frequent cemented zones. Based on project criteria for Reach F and G levee construction, AECOM concluded that the site is generally unsuitable for Type 2 fill. However, the materials predominantly meet or can be blended to meet requirements for Type 1 and Type 3 fill. Due to highly variable subsurface conditions, cementation, and medium-to-high plasticity, the materials will require thorough processing, moisture conditioning, and blending to be suitable for construction, while the organic-rich surficial topsoil layer must be excluded.
