Report
RECOMMENDATION:
It is recommended that the Monterey County Water Resources Agency Board of Directors:
Approve Amendment No. 1 to the Agreement for Services with Graniterock Company to increase the dollar amount by $215,000 for a total contract not to exceed $315,000 for Post Winter Storm 2023 Cleanup and Repairs at the Salinas River Diversion Facility; and authorizing the General Manager to execute the Amendment.
SUMMARY/DISCUSSION:
After the Winter Storms in January and March of 2023, the Salinas River Diversion Facility was heavily impacted by the river levels and flows. After approximately 23,000 cfs flowed through the channel at the facility, damage and debris/silt deposition occurred throughout the site. An initial cleanup of the site occurred in April 2023 to allow access to the facility to operate. This included debris and silt removal deposited on top of the site and in the regulating weir where debris, including trees, wedged into the structure. The site was restored to a minimum level for access and operations for the 2023 CSIP irrigation season. Pre-season inspections occurred and determined operations were safe while the damages could be assessed, and repairs scheduled.
A post storm damage assessment was conducted, as well as inspections from the Division of Safety of Dams which determined further cleanup and repairs were necessary. Of the noted damages, there was out of channel and in-channel damages/ disturbances. The out of channel project was put out to bid in March 2024 to expedite the overall repairs by excluding the more difficult to access in-channel repairs. In May 2024, a qualified contractor was chosen, and final contracting was conducted. The scope of work was broken into two phases, cleanup and repairs. The initial contract was conducted on a Time and Material fee schedule to perform the necessary final cleanup and debris removal in phase 1. This was a contract not to exceed $100,000. This phase split up was conducted to expedite the project and utilize remaining funds from FY 24.
The cleanup was completed and now Amendment No.1 will conduct the Phase 2 Scope- Out of Channel Repairs which include concrete spalling repair, displaced rip rap replacement, fish ladder panel damage repair, etc. Amendment No. 1 will add $215,000 to the contract, bringing the total not to exceed amount to $315,000 and add the repair items into the scope of work. At the end of phase 2, the out of channel work will bring the facility to pre-storm condition. In-channel repair will occur at a later time due to the development of further project planning, permitting, and timing considerations to weather and operations.
The MCWRA Finance Committee recommended approval of this amendment at the August 2024 meeting.
