| | | | | | | | OBJECTIVE
To recommend that the City Council approve payment to Southern California Gas Company to relocate a gas line as part of Project No. CP1286000 – Orangewood Avenue – Dale Street Water Improvements Project. |
| | | | | | | | BACKGROUND
On September 27, 2022, City Council awarded a contract with Stephen Doreck Equipment Rentals, Inc. for the construction of Project No. CP1286000 – Orangewood Avenue – Dale Street Water Improvements Project. This Project was categorized as a priority project in the latest Water Master Plan to address fire flow deficiencies. The project consists of upsizing 6-inch water mains to 8 and 12-inch water mains, and installing new fire hydrants. |
| | | | | | | | DISCUSSION
During the design phase of this project, the consultant and City staff discovered a conflict of utility lines involving a high pressure gas main, a 2-inch gas main, and a sewer and storm drain. It was determined that relocation of the 2-inch gas main was the only alternative that would allow the installation of the new water main in a feasible and safe way. City staff reached out to the Southern California Gas Company on May 17, 2022, to propose the gas line relocation and requested requirements to initiate the gas line relocation process. On November 8, 2022, Southern California Gas Company responded and provided a proposed scope of work and cost estimate. The general contractor’s work at this intersection is dependent on the completed work performed by the gas company. Any delay from the gas company will put the general contractor’s work on hold.
The scope of work for the gas relocation includes abandoning the section of the main in conflict, installing 20-feet of 2-inch main at a different elevation and new fittings. Traffic control plans, signs and devices are included in the total cost. This is to ensure safety measures are in place at this heavily trafficked intersection. It is anticipated the construction will be completed within 10 to 15 working days. The total cost for this work is approximately $120,878.41. Actual costs may vary. To avoid any further delays in completing this priority project to help ensure fire flows are met, Staff is recommending issuing payment to the Southern California Gas Company to make arrangements for the gas line relocation. |
| | | | | | | | FINANCIAL IMPACT
There is no impact to the General Fund. This project will be absorbed in the fiscal year 2022-2023 Capital Improvement Budget, and will be financed with Water Enterprise Funds in the amount of $120,878.39. |
| | | | | | | | RECOMMENDATION
It is recommended that the City Council:
- Authorize payment in the amount of $120,878.39 to the Southern California Gas Company for Gas Line Relocation for Project CP1286000 – Orangewood Avenue – Dale Street Water Improvements.
- Authorize the City's Water Services Manager and/or the Public Works Director to execute Southern California Gas Company's Collectible Work Authorization and all other documents necessary to authorize the work.
