This document is a Geotechnical Report for the CRIP Lateral 73-36 Check Structure, prepared by DOWL for the U.S. Bureau of Indian Affairs. It provides an evaluation of subsurface conditions and geotechnical recommendations for the reconstruction of the check structure and headgate.

• Site Conditions: The project area is in southwest Arizona, part of the Colorado River Irrigation Project (CRIP). The existing check structure is in poor repair and requires complete replacement.
• Proposed Construction: Replacement of the 73-36 Check 1 structure (approx. 50 ft wide, 48 ft long) and a new headgate structure.
• Geology: The valley subsurface soil consists of sand, silt, and gravel. Bedrock in the area is volcanic rock.
• Investigation: Two test pits (TP-1 and TP-2) were excavated to approximately 11 feet. Laboratory testing was performed on soil samples.
• Subsurface Conditions: Soils generally consist of silty sand and poorly graded sand with silt. Groundwater was encountered at 8 feet in TP-2.
• Seismicity: The site is in an area of Quaternary faulting. The site is classified as Site Class E for seismic loading, with a potential for liquefaction.
• Recommendations: The proposed structures can be supported on a conventional mat/footing foundation. Recommendations are provided for foundation design parameters, lateral earth pressures, embankment slope stability, and earthwork.
• Liquefaction Potential: Loose sands are potentially liquefiable under seismic events, which could lead to settlement. The Bureau of Indian Affairs has decided not to pursue further exploration or mitigation for liquefaction due to cost and risk.
