body
BACKGROUND
The Orange County Sanitation District (OC San) has a project in the city of Cypress that will replace the existing 18-inch sewer with a new larger 24-inch sewer pipeline in the same alignment. This project will also replace the manholes to accommodate the new larger pipe. One of the manholes to be replaced is located near a Golden State Water Company (GSWC) water pipeline. As part of the project, the area around the manhole will be excavated and utilities within that area will be relocated or protected in place.
RELEVANT STANDARDS
* Maintain collaborative and cooperative relationships with regulators, stakeholders, and neighboring communities
PROBLEM
The GSWC water pipeline conflicts with OC San's proposed construction. This pipeline needs to be relocated and GSWC needs to perform the work to ensure it complies with drinking water standards.
PROPOSED SOLUTION
Approve an agreement with GSWC for the relocation of GSWC water pipeline. GSWC will move the pipeline out of the conflict zone within the OC San construction work area.
TIMING CONCERNS
If the approval of the agreement is delayed, it could delay the advertisement of the project, which is currently planned for Spring 2024.
RAMIFICATIONS OF NOT TAKING ACTION
The construction costs will increase and the schedule may be extended.
