Resilient St. Vrain: Restore & Revitalize

  • Fully restore the St. Vrain Greenway, which was extensively damaged by flooding. This involves reconstructing several sections of the greenway as construction moves upstream.

Ultimately, the St. Vrain Creek through the city will be able to safely convey up to 100-year flood flows by reducing the size of the floodplain. These improvements will also help protect our community against more likely flood flows, such as 5-, 10-, or 25-year levels.

The map below shows how the floodplain is expected to shrink, resulting in lower flood risk for many properties throughout Longmont. Click on the map to open a larger version. Find out whether your property is at risk for flooding by checking the Floodplain Inquiry Map >

Construction on this very large project is taking place in phases over several years beginning on the downstream end. Learn about the phases and anticipated timeline >

Hear Longmont City Manager Harold Dominguez and Public Works & Natural Resources General Manager Dale Rademacher talk about the importance of restoring the St. Vrain Greenway through work on Resilient St. Vrain in the 1-minute video below.
