Resilient St. Vrain
- Fully restore the St. Vrain Greenway, which was extensively damaged by flooding. This involves reconstructing several sections of the greenway as construction moves upstream.
- Protect people and property (including both public and private infrastructure) by making the St. Vrain Creek through Longmont more resilient to future flooding. Longmont is working to build community resilience to all types of disasters >
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 >
- Incorporate environmentally sensitive planning into the project, including:
- Maintaining and enhancing the natural habitat for wildlife and fish
- Creating wetland areas to help clean water that makes its way into the creek, and
- Incorporating natural channel design techniques such as using natural materials like rocks and plantings to create habitat and stabilize creek banks.
- Honor previous planning efforts in the project's design. Many existing plans and codes influenced the project design >
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 >
