Project Description The City currently owns and operates the Butterfield Basin, which is an off -stream basin intended to support flood control activities associated with the Butterfield Channel. This project will make improvements to the basin that will serve three purposes: 1) groundwater recharge, 2) state mandated trash capture compliance, and 3) improved flood protection. The project will convert the basin to an on - stream basin and adjust the outflow to retain stormwater onsite for the groundwater recharge and trash capture purposes. This project will be completed by FY 2026-27. After completion of the Butterfield Basin , improvements to allow additional storm water to flow from the Fisher Basin to the Butterfield Channel will be made in FY 2027 -28. Project Justification The project will improve groundwater recharge promoting sustainable water supply, assist the City in meeting state mandated trash capture requirements, and improve flood protection for the Butterfield Channel. The City has also received $2 million in State grant funding for the groundwater recharge purpose of the project.
