Lincoln/Willow Storm Sewer Upgrades

Conceptual rendering of outfall into Poudre River

Project Description

From January 2015 - May 2016, Fort Collins Utilities replaced old and undersized storm sewer infrastructure in the Downtown River District. The project improved drainage, added water quality treatment and increased safety for area properties and transportation systems.

Construction included the addition of a water quality diversion structure and outfall into the Poudre River at Lincoln Avenue and Willow Street. A 48-inch storm sewer and inlets were constructed along Willow Street and an 8-inch waterline was added adjacent to Willow Street from Lincoln Avenue to Linden Street.


Project Purpose and Benefits

The previous storm sewer infrastructure in the Downtown River District was aged, undersized and a risk to existing properties and area transportation during major storm events.

Additionally, many storm sewer lines were routed below private property and difficult to access for repairs.

This project improved drainage and maintenance issues by adding adequately sized infrastructure to public right-of-way. It also added water quality treatment to the area by diverting runoff to ponds in the Udall Natural Area.



NOTE: Following the storm sewer project, City of Fort Collins Engineering constructed improvements along Lincoln Avenue between Lemay Avenue and the Lincoln bridge, including replacement of the bridge. This project was completed in summer 2017.
