Body
COUNTY AND CHIEF EXECUTIVE OFFICER GOALS & OBJECTIVES
Provide for the Safety, Health and Social Service Needs of County Residents.
FINANCIAL IMPACT
Approval for this item will not result in the use of Discretionary General Funding (Net County Cost) as the Department of Public Works - Solid Waste Management Division (SWMD) is financed by fee revenue. SWMD establishes fees that are charged to the public and other agencies for utilization of the County’s Waste Disposal System. The contract cost of $3,186,540, and any of the proposed contingency fund for the Unit 5 Pre-Development Investigation at the Mid-Valley Sanitary Landfill (MVSL) (Project), will be funded by SWMD fee revenue. Sufficient appropriation and revenue have been included in the SWMD 2022-23 budget and will be included in future recommended budgets.
BACKGROUND INFORMATION
MVSL is located in the City of Rialto, northwest of the intersection of Alder Avenue and State Route 210. The site occupies approximately 448 acres of which 408 are permitted for refuse disposal. The site is divided into five separate waste management units. The Project will enable SWMD to investigate potentially impacted soil and groundwater conditions near the planned Unit 5 expansion area. The Project consists of drilling eighteen borings at various depths for soil sampling and developing three groundwater wells for monitoring. The results of the investigation will determine site conditions and the necessity to implement any mitigation measures. Developing Unit 5 will provide additional landfill airspace for the continued disposal needs for the County.
The Project as described above has been reviewed by the Department of Public Works, Environmental Management Division (EMD) for compliance with the California Environmental Quality Act (CEQA). EMD concluded the Project, as proposed, is consistent with normal operating procedures as evaluated in the Mid Valley Landfill Expansion Environmental Impact Report, which was approved by the Board of Supervisors (Board) on February 10, 1998 (Item No. 81 and included in Notice of Determination No. SCH 91042005. As such, no further CEQA compliance is required.
On September 13, 2022 (Item No. 49), the Board approved the Project’s plans and specifications and authorized the Director of the Department of Public Works to advertise the Project for formal bids. The Project was released on the County Electronic Procurement Network (ePro) (ePro No. PWG123-SOLID-4826) on September 22, 2022 and advertised in the Daily Press and Precinct Reporter newspapers on September 22 and September 29, 2022. A notice inviting bids was also provided to specified construction trade journals as required by Public Contract Code section 22036. A mandatory pre-bid meeting and job walk was held on Thursday, October 6, 2022 and was attended by only one firm. Consequently, with only one potential responsive bidder, SWMD recommended to re-advertise the Project more broadly to potentially obtain more competitive bids and give additional bidders an opportunity to submit a bid.
This item supports the County and the Chief Executive Officer’s goals and objectives of providing for the safety, health and social service needs of County Residents by operating in a responsible manner to provide continued disposal services.
Following Board approval of this item, the Project is anticipated to commence in June 2023 and be completed by September 2023.
PROCUREMENT
