Flood Preparedness, Longmont Flood Preparedness and Spring Runoff Information
Although Longmont experienced significant flooding in September 2013, it doesn't mean that it won't happen again soon. The odds of a major flood occurring are the same regardless of when the last flood occurred.
There is no way to predict how or when the next flood will occur, and it's unlikely that flooding will happen in the same way in the future. The magnitude, duration, scope and path of flooding will vary and cause different impacts. Floods can happen at any time, with little or no warning. The best course of action is to be alert and prepared.
The City of Longmont wants you to be prepared for any flooding, landslide or debris flow situations that arise due to normal spring runoff, intense rain events and/or abnormal land conditions following the 2013 Flood.
Please explore the "Flood Preparedness" sub-pages in the menubar to your left to get all the details and information.

Know the Risks
(taken from Boulder County's Post-Flood Community Preparedness Guide)
Flash Flooding | Thunderstorm-Related Flooding | Landslide | Debris Flow | Spring Runoff
As a result of last year’s rain and flooding, the risks of flash flooding may increase this year because of the following reasons:
- Reduced creek and river capacity due to increased sediment deposits, rocky debris and location changes of creek banks
- Woody debris deposits in and along rivers and creeks potentially causing debris dams and subsequent flash flooding
- Debris flows and landslides may cause access issues and obstruct creek flows
- Altered locations and conditions of rivers and creeks may impact structures and infrastructure at risk (i.e. homes, roadways, culverts and bridges)
