Plans_-_2024_Citywide_Sewer_Storm_Lining_Project.pdf

The document is a set of engineering plans for the 2024 Citywide Sewer/Storm Drain Lining Project by the City of Santa Cruz Public Works Department. The project involves rehabilitation and lining of various sanitary sewer and storm drain pipeline segments across multiple streets in Santa Cruz, including Morrissey Boulevard, Centennial Street, Oxford Way, De La Costa Avenue, Gault Street, Columbia Street, Stockton Avenue, Allegro Drive, and Laurent Street. The project utilizes Cured-In-Place Pipe (CIPP) lining method to rehabilitate existing underground infrastructure. The planned work includes pipeline lining of varying lengths (ranging from 47 to 375 feet) with pipe diameters between 6 and 18 inches, and includes manhole rehabilitation at multiple locations.

The project documents specify detailed technical requirements for the contractor, including confirmation of existing pipe material, diameter, and length, dye testing of laterals, and addressing defects less than a Grade 3 condition. The existing pipeline materials are primarily Vitrified Clay Pipe (VCP) and Reinforced Concrete Pipe (RCP), with most sections having lateral reconnections ranging from 0 to 11 connections. The project is part of the city's infrastructure maintenance strategy, aimed at extending the life of underground utility infrastructure and preventing potential failures. The engineering plans are dated 5/14/2024 and include comprehensive mapping and technical schedules for each street segment, providing precise details about the rehabilitation work to be performed.
