Rainbow Green Street Project
Water Quality Project | Estimated Completion August 2026

Currently under construction, this project will use green infrastructure to capture and filter pollutants from agricultural runoff, helping protect local waterways.
Conceptual rendering only. Final design is subject to change based on construction limitations.
Construction: What to Expect
Construction began in April 2025 and is expected to be completed in Summer 2026.
Project area includes segments of Fifth Street, Huffstatler Street, and Rainbow Valley Boulevard.
During construction, the County will make every effort to minimize disruptions along the roadways. All construction will occur in the public road right-of-way to avoid impacts to private property owners. There will be temporary impacts to utilities, and to both vehicular and pedestrian traffic. Traffic control measures, including signage placed prior to and during construction, will be implemented to ensure the safety of our customers.
