GENERAL MANAGER'S RECOMMENDATION
recommendation
RECOMMENDATION: Recommend to the Board of Directors to:
Approve an agreement with Forest Lawn Memorial-Park Association for construction access and staging, sewer installation, and pavement rehabilitation in coordination with the Los Alamitos Sub-Trunk and Westside Relief Interceptor Rehabilitation, Project No. 3-64C for an amount payable to Orange County Sanitation District not to exceed $813,000.
body
BACKGROUND
The Orange County Sanitation District (OC San) is rehabilitating the Los Alamitos Sub-Trunk in the city of Cypress by replacing the existing 18-inch sewer with a new, larger 26-inch sewer pipeline in the same alignment. OC San currently has an easement with Forest Lawn Memorial-Park Association (FLMPA) for the portion of the alignment that traverses FLMPA’s property. This part of the project will upsize the pipe using both open cut and trenchless methods, replace manholes to accommodate the new larger pipe, and repave the area above the pipe and manholes.
RELEVANT STANDARDS
• Maintain collaborative and cooperative relationships with regulators, stakeholders, and neighboring communities
• Maintain a proactive asset management program
PROBLEM
FLMPA has asked OC San to add sewer stub outs and pavement beyond what is required for the project, which will result in additional construction costs. OC San’s proposed sewer construction requires a temporary construction easement and staging area from FLMPA to perform the work.
PROPOSED SOLUTION
Approve an agreement with FLMPA for the Los Alamitos Sub-Trunk and Westside Relief Interceptor Rehabilitation, Project No. 3-64C, to reimburse OC San for the additional project scope requested by FLMPA. The exact reimbursement cost will be based on the bid price of the requested work. This agreement also includes a staging area and temporary construction easement for OC San free of charge.
TIMING CONCERNS
If the approval of the agreement is delayed, it could delay the advertisement of the project, which is currently planned for early spring.
RAMIFICATIONS OF NOT TAKING ACTION
Without this agreement in place, OC San may have to reimburse FLMPA for a temporary construction easement and staging area.
