Major flooding on Sept. 11-15, 2013, impacted several areas throughout the City of Longmont. As of September 2016, repairs to most areas damaged by the flooding were completed. The focus now shifts to efforts to improve our community's resilience to future flood events, which will take time and will have lasting effects on our community.
As we all work together to rebuild, it is our goal to keep the community informed and involved.
Informational signs posted along the St. Vrain Greenway offer an overview of Longmont's flood recovery and protection efforts since the 2013 flood. The signs were unveiled in September 2016, in observation of the third anniversary of the flooding.
Signs may be viewed at several locations along the St. Vrain Greenway trail, as well as at the Longmont Recreation Center and the Civic Center.
