12th Street Stormwater Outfall

Project Background

The City of Greeley is building a new underground storm drain system to prevent flooding in the downtown area. Phase 1 of the project is underway, close to 10th Street and U.S. 85 near the Poudre River. This phase involves infrastructure, public art, river restoration, and an extension of the Poudre Trail.

Phases 2 through 4 will continue along 12th Street in downtown Greeley.

This project is necessary to reduce flooding in the area. In the past, floods have caused problems with traffic and damaged homes and businesses.

Stay tuned for more updates as we work towards a safe and more resilient Greeley.

  • December 2022-January 2023: Water line installation - 1st Avenue Wastewater Plant
