SCOPE:


BACKGROUND:

A major flood event in September 2013 severely impacted the City of Longmont, especially along the St. Vrain Creek. Flooding affected public and private properties, damaged infrastructure, and temporarily shut down roads and bridges effectively cutting the City in half. A flood event of this magnitude had not been experienced in Longmont in over 100-years, and it served as a reminder that the risk of major flood events is real and ever-present. From this disaster comes the opportunity to protect the community while restoring the St. Vrain Creek channel and improving its resilience to future flood risk.

The Resilient Saint Vrain Project (RSVP) is the City’s multi-year, multi-phase project to restore and revitalize the creek corridor through Longmont. Izaak Walton Reach 1 is the next phase of this critical resiliency project that once complete will protect people, property and infrastructure from future flood risks.
