These engineering design drawings from the Dane County, Wisconsin Department of Public Works detail typical cross-section and construction details for the Sanitary Landfill No. 1, specifically showing existing and proposed site configurations. The drawings include technical specifications for:

1. Typical Cross Section Details: Showing existing and proposed landfill geometry, including topsoil, clay layers, intermediate cover, and refuse placement. The cross-sections illustrate precise elevation changes and layering strategies for landfill construction and capping.

2. Berm/Cap Details: Diagrams depicting existing and proposed berm configurations, with specific notes on topsoil placement, root zone/cover soil, and refuse positioning.

3. Gas Extraction Well Details: Technical drawings of gas extraction well configurations, including both existing and proposed designs. These show precise specifications for pipe connections, bentonite seals, butterfly valves, and protective steel casing.

4. Additional Technical Components: The drawings include detailed schematics for cleanout riser details, pipe connections to existing manholes, bentonite-clay seal details, and protective steel casing cover details, providing comprehensive engineering specifications for landfill infrastructure.
