Written by GovTribe AI · Apr 11, 2025

These are engineering design and construction plans for Pipeline Project CIP21002 prepared by the Helix Water District located in La Mesa, California. The comprehensive project involves replacing approximately 5,470 linear feet of aging cast-iron water pipes from the 1940s and 1950s across multiple streets, including Melody Lane, Kiowa Drive, Guessman Avenue, Date Avenue, Spring Street, Keeney Street, Mohawk Street, Murial Place, Cinnabar Drive, and Panorama Drive. The proposed infrastructure upgrade will replace existing 6-inch, 8-inch, and 10-inch diameter pipes with 6,040 linear feet of new 8-inch and 10-inch diameter PVC pipes. Additionally, the project includes abandoning 150 linear feet of 6-inch asbestos-cement pipe in a problematic easement and replacing 1,200 linear feet of 6-inch asbestos-cement pipe on Culowee Street with 10-inch PVC pipe.

The detailed engineering plans, spanning 17 sheets, provide comprehensive technical specifications, profile drawings, utility locations, and construction requirements. The project documents are professionally stamped and certified by a registered professional engineer with license expiration on 6/30/24. The plans include extensive notes about installation procedures, material specifications, connection requirements, and adherence to local municipal codes and water district standards. While specific budget details are not visible in the provided documents, the project appears to be a critical infrastructure improvement initiative aimed at modernizing and enhancing the water distribution system's reliability and efficiency in the La Mesa area.
