Butterfield Basin Online Conversion

The Butterfield Basin Online Conversion project, managed by the City of Morgan Hill in California, involves converting the Butterfield Basin from an offline to an online configuration. Located at the southwesterly corner of the intersection of Maple Avenue and Seymour Avenue in Morgan Hill, the project focuses on enhancing existing storm drainage facilities to improve environmental protection. The scope of work includes the construction of a sediment capture basin and regional trash capture devices, as well as the creation of a flat bottom area designed for stormwater capture and infiltration. These improvements are intended to facilitate groundwater recharge, increase water source resilience, and protect downstream creeks and environments. The project is classified under NAICS code 237990 and was posted as a forecast on January 13, 2026. According to the Notice of Exemption filed on December 18, 2025, the project is eligible for a categorical exemption under section 15308 for enhancing storm drainage facilities. Kristian Wallace, Associate Engineer, serves as the primary point of contact for the agency.
