September 2013 Flood

 « Return to Flood Info

From Sept. 11 through 15, 2013, the Front Range region experienced significant rainfall, causing flooding, loss of life, and widespread damage. More than 18 inches of rain fell in the area causing 25 to 100- year flooding along Boulder's 15 drainageways. As a result, Boulder County, including the City of Boulder, were designated a Federal Disaster Area. Below includes information on  recovery goals, funding from the Federal Emergency Management Agency (FEMA), progress to date and council memos related to the flood recovery effort. 

Since September 2013, staff from the City of Boulder and Mile High Flood District (MHFD) has been collecting flood damage information from the community, site visits, surveys and FEMA data. Staff will continue to evaluate and prioritize projects based on feedback from neighbors, consultants, stakeholder organizations, the community, advisory boards and committees, and City Council.
