Yuba City took another step forward on its wastewater treatment plant outfall diffuser project June 16, approving amendment six to the Jacobs Engineering contract and adding $613,883 for bid-phase services, according to the city council meeting summary.
Deputy Public Works Director Jacob Bradford presented the item to the council. The project has been part of the city’s long-running wastewater planning, and the meeting materials say the diffuser work is now linked to a proposed $50 million state revolving fund loan. Staff also said the project could move through construction from 2027 through 2029 if financing and bidding proceed as expected.
The meeting summary says the amendment is for bid-phase services and that the project’s estimated scale includes about $41 million in construction costs and about $8.8 million in soft costs. The same summary says the contract began under Jacobs’ former name, CH2M Hill, and has been amended several times before the latest action.
Council action on the item was unanimous in the meeting summary. The record available here does not show the full discussion beyond the summary, and it does not include the final status of the state loan or any remaining permitting steps.
The outfall diffuser work was one of several finance and capital items the council handled that night, alongside new reserve and contingency policies and the city’s 2026-27 budget.
