These engineering drawings are for the Avondale Water and Sanitation District (AWSD) Water and Sewage Facilities Plan, prepared by Wright-McLaughlin Engineers in July 1970. The detailed plan set consists of four sheets showing water and sewage infrastructure mapping across multiple street grids including 2nd Street, 1st Street, North Lane, Edson Avenue, and other local streets. The drawings include precise topographical and infrastructure details with multiple line profiles (labeled A-Line, A-10 Line, A-15 Line, etc.) indicating water and sewage facility locations, elevations, and connection points.

The technical drawings capture extensive engineering specifics including underground utility placement, basement locations, street rights-of-way, proposed and existing infrastructure lines, grade elevations, and specific station markers (identified as STA with numerical references). Each sheet is meticulously drafted with north-oriented site plans, detailed cross-section profiles, and engineering notation. The documents are part of Contract No. G-841 and bear the engineering firm's official seal, indicating they are official construction documentation for municipal water and sewage infrastructure planning in what appears to be a suburban or municipal development area.
