GENERAL MANAGER'S RECOMMENDATION
recommendation
RECOMMENDATION:
Approve Utility Agreement No. OCSD-1005 between the Orange County Sanitation District and the Orange County Transportation Authority agreeing to specific terms, conditions, and funding obligations regarding the relocation and protection of the Redhill Relief Sewer at State Route 55 in the City of Santa Ana.
body
BACKGROUND
The Orange County Transportation Authority (OCTA) is implementing the State Route 55 Improvement Project (SR-55 Improvement Project) to widen State Route 55 between Interstate 5 and Interstate 405.
RELEVANT STANDARDS
• Maintain collaborative and cooperative relationships with regulators, stakeholders, and neighboring communities
• Protect Orange County Sanitation District assets
PROBLEM
The SR-55 Improvement Project will widen the freeway right-of-way and add a travel lane. An existing Orange County Sanitation District (Sanitation District) manhole is located where the additional lane will be constructed and the sewer under the added freeway lane is unprotected.
PROPOSED SOLUTION
Conduct a project to relocate a portion of the sewer and construct a casing at the unprotected sewer segments underneath the proposed right-of-way addition. OCTA has agreed to fund the relocation and protection of the Sanitation District sewer. To receive the funding, the Sanitation District must enter into a Utility Agreement with OCTA.
TIMING CONCERNS
The relocation and protection of the sewer must begin by June 2021 to align with OCTA’s SR-55 Improvement Project’s schedule.
RAMIFICATIONS OF NOT TAKING ACTION
The Sanitation District sewer may be damaged by the OCTA project.
PRIOR COMMITTEE/BOARD ACTIONS
N/A
ADDITIONAL INFORMATION
A design task order under an existing Master Design Services Agreement has been procured and negotiated with a design consultant for this project. The task order will be awarded upon Board Approval of this Utility Agreement. Staff will advertise the project for construction pursuant to California Public Contract Code Section 20103.8 and estimates the construction to start in June 2021.
CEQA
The relocation and protection of the Redhill Relief Sewer is included in the Initial Study/Mitigated Negative Declaration/Environmental Assessment, prepared by Caltrans and OCTA, for the SR-55 Improvement Project.
FINANCIAL CONSIDERATIONS
This request complies with authority levels of the Sanitation District's Purchasing Ordinance. This item has been budgeted (Budget Update, FY 2019-20, Appendix A, Page A-8, Small Construction Projects Program, Project M-FE) and is sufficient for the recommended action. Costs for the project will be reimbursed by OCTA.
