Attachment_04_-_MMB_Drawings_Set_(Revised)_0001.pdf

This is a location map and technical drawing set for canal repairs in Yuma County, Arizona, prepared by the U.S. Bureau of Reclamation. The document identifies the project location along the U.S.-Mexico border near the Colorado River and provides detailed engineering specifications for concrete lining work and related infrastructure modifications.

The first page contains a comprehensive location map showing bypass reference points, multiple bridge and drain locations, and numbered sections for concrete panel work. The map identifies required concrete panel work locations (marked as FY26 in the legend) and notes that work may represent multiple tasks across the project area. The second page presents technical cross-sections and details for typical concrete lining construction, including standard section modes, concrete lining details at expansion joints (Type 1 and Type 2), bypass configurations, and groove details. Key specifications include 12-inch concrete lining with specific expansion joint dimensions, 1-foot side slopes, and reinforcement requirements. The drawings show representative multiple tasks distributed across the mapped area, with detailed callouts for joint spacing, concrete depth, and structural reinforcement. The project number is identified as 923-303-60177, and the document indicates this is part of a broader Canal Repairs FY 2026 initiative.
