Construction Underway on 12th Street Drainage Project

Water News Release

Construction started in December on a project to mitigate flooding in downtown Greeley.  

The first phase of the 12th Street Storm Outfall project is part of a larger plan. Over the next decade, it will create an underground storm drainage system to safely divert extra rainwater to the river. An outfall is the point at which stormwater leaves the pipe system and enters the river. 

The improvement to the drainage system in Greeley’s downtown neighborhoods benefits residents and property owners by reducing flood damage. Significant damage occurs when excess rainfall is not diverted away from homes and businesses.  

The first phase includes relocating utilities, followed by construction of a new storm outfall facility in Spring 2023. A storm drainage facility is being built next to the Cache la Poudre River near 10th Street and U.S. 85. Officials expect construction to finish in Summer 2024. 

The city received a $1.6 million grant from Federal Emergency Management Agency (FEMA) grant to help fund future design phases of the drainage plan. Those phases will create a large storm drain system on 12th Street between 2nd and 8th Avenues.  

FEMA also awarded the city a $250,000 grant for the first phase of design.
