Ralston Creek Flood Alternatives Open House

The U.S. Army Corps of Engineers, in cooperation with the City of Arvada and the Urban Drainage and Flood Control District, will hold an open house on Tuesday, September 12, to gather public input on preliminary alternatives currently being evaluated to reduce flood risk and improve public safety along approximately 3.5 miles of Ralston Creek within the city limits of Arvada.

The meeting will take place from 6 - 8 p.m., with a formal presentation at 6:30 p.m., at Arvada City Hall (Atrium), 8101 Ralston Road in Arvada, Colorado. Residents and others interested in the project will have the opportunity to learn more about how the flood risk management study has progressed since the May 2017 public scoping meeting and provide input on each of the preliminary alternatives. Information on the study can be viewed at

BACKGROUND: Historical flooding in Arvada has damaged city streets, sewer and water infrastructure, homes and businesses, and stream channels and canals. Over the past 40 years, new development in the Ralston Creek watershed has increased the threat of flash flooding in Arvada. Today, flooding impacts approximately $72 million in property, including over 400 homes, located in the 100-year floodplain. The feasibility study will analyze conditions along Ralston Creek from Beech Street (upstream limit) to the confluence with Van Bibber Creek (downstream limit) along with the engineering feasibility, economic viability, and environmental considerations of potential flood risk management solutions.

For more information about the public meeting, contact Patrick Dougherty with the City of Arvada at 720-898-7642 or Alex Mueller with USACE Omaha District at 402-995-2045.
