IFB‐MD‐20077‐DR - Resilient St. Vrain Project: Izaak Walton Reach 1 – Utility Relocations

BACKGROUND:
A major flood event in September 2013 severely impacted Longmont, especially along the St. Vrain Creek. Flooding affected public and private properties, damaged infrastructure, and temporarily shut down roads and bridges 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) will restore and revitalize the creek corridor through Longmont. RSVP is a multi-year, multi-phase project that is currently in various stages of design, construction and completion. Planned channel improvements necessitate relocation of certain utilities and specifically an existing sanitary sewer main and water line near Boston Avenue at St. Vrain Creek.
