The U.S. Army Corps of Engineers (USACE), in cooperation with the City of Longmont, will hold an open house and public meeting on Wednesday, Sept. 18, from 5 to 7 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, and information stations will be available before and after the presentation. (A previous news release listed different times for the open house and formal presentation.)

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

The draft report, which includes an Environmental Assessment, 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, property and infrastructure along St. Vrain Creek, and selection of the proposed plan.

The USACE study reach corresponds with the Resilient St. Vrain project reach known as Izaak Walton Reach 2. 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.

The draft feasibility report and Environmental Assessment (EA) may be viewed online at https://www.nwo.usace.army.mil/Missions/Civil-Works/Planning/Planning-Projects/LongmontCO/. A paper copy of the report is available at Longmont Public Library, 2nd Floor Reference Desk, 409 Fourth Ave.

Public comments on the draft report and EA will be accepted for a 30-day period. Email your comments on the report to cenwo-planning@usace.army.mil or mail to: U.S. Army Corps of Engineers, Omaha District, CENWO-PMA-A, ATTN: Tim Goode, 1616 Capitol Avenue, Omaha, NE 68102-4901. Comment forms also will be available at the Sept. 18 public meeting. Comments must be postmarked or received by 5 p.m. MST Oct. 4, 2019.
