Background
The I Street/32nd Street Storm Drain Improvement Project (Project) is located in the North Highlands area in the Robla Creek watershed. The Project area is bound by low-density residential parcels east of 32nd Street, industrial land use west of 32nd Street and south of I Street, and McClellan airfield to the west. The watershed area flows to Robla Creek from south to north via drainage ditches and overland sheet flow. The existing public drainage system for this area flows through a private industrial property within drainage easements.
Project Description
The Project will route drainage flows away from the existing system to a new drainage pipe system located within the County road right-of-way of I Street and 32nd Street. The new system will connect to Robla Creek via the existing concrete bridge structure on 32nd Street. Improvements will upgrade and add capacity to the existing system, improve existing localized flooding, re-route the public drainage system from private properties to public road right-of-way, bring the system up to current drainage standards, and provide a public drainage system that can be used by future development.
On July 23, 2024, the County Board of Supervisors (Board) adopted the Mitigated Negative Declaration environmental document and approved the Project. See the project map below for project location and planned improvements.
Project Update
The project is in the final stages of design and is scheduled for construction in summer 2026. The project will be presented to the Board for construction advertisement approval on November 4th, 2025.
