The U.S. Army Corps of Engineers, in cooperation with the City of Longmont, Colorado will hold a flood risk management study open house Sept. 18, from 5:00 to 7:00 p.m. at the Longmont Museum, 400 Quail Road.

There will be a brief, formal presentation at 6:15 p.m. on information contained in the recently released draft feasibility study report, followed by an open house.

The draft report provides information on the need for the project, current conditions of the project area, identification of opportunities to reduce flood risk, development of various alternatives to reduce flood impacts to life safety and property along St. Vrain Creek, and selection of the proposed plan.

The recommended plan includes a levee on the south side of the Izaak Walton Pond Nature Area, channel widening and benching to contain the 1% Annual Chance Exceedance (ACE) event, replacement of the Boston Avenue Bridge, and a grade control downstream of Sunset Street Bridge.

This flood risk management study builds on Resilient St. Vrain, Longmont’s extensive, multi-year undertaking to fully restore the St. Vrain Greenway and increase resiliency of the St. Vrain Creek channel to reduce future flood risk to the community. The Resilient St. Vrain project was developed by the City of Longmont in response to the catastrophic flooding in September 2013.
