28th Street Stormwater Infiltration Project

The City of Manhattan Beach is planning the 28th Street Storm Drain Infiltration Project to manage stormwater runoff by diverting flow from an existing County-owned storm drain beneath 28th Street through a new pipeline routed southeast along Manhattan Avenue. The diverted water will be directed to a pretreatment system that includes trash removal and sedimentation to clarify the runoff before it is distributed into a network of drywells situated within and around a nearby parking facility, allowing for natural infiltration into the ground. This project is being advanced through an addendum to a previously adopted Mitigated Negative Declaration, indicating adjustments or updates to earlier environmental review findings without requiring a full Environmental Impact Report. The initiative aims to improve local drainage, reduce surface flooding, and enhance stormwater management while minimizing environmental impacts through subsurface infiltration. The project is officially forecasted by the City of Manhattan Beach, with no solicitation number assigned as of now, and is slated for public notice on May 28, 2026. The place of performance is consistently identified as Manhattan Beach, California, with a ZIP code of 90266. Gilbert Gamboa, the City Engineer, serves as the primary point of contact for inquiries and can be reached via email or phone. Although specific NAICS codes, set-aside classifications, or contracting mechanisms are not detailed, the project falls under municipal infrastructure development and reflects the city’s commitment to sustainable stormwater practices. The official project link is provided for public access to environmental documentation and records.
