Prepare For Flood Season

In Littleton, the typical flood season is from mid-April to mid-September, due to spring rains or summer high intensity thunderstorms.  Flash flooding from very heavy rain can cause rapid runoff in just a few minutes.  It often causes flooding in streets and low lying areas.  The numerous small streams in Littleton, such as Little’s Creek, Lee Gulch, and Slaughterhouse Gulch, are subject to this common type of flooding.  At roadway crossings of these creeks, the road surface could flood.  Never attempt to cross a flooded road, or walk or bike across a flooded trail. 

One way to mitigate the impact of a flood is to have flood insurance.  Premiums can vary depending on the risk at a particular property.  Littleton participates in the Federal Emergency Management Agency (FEMA) National Flood Insurance Program (NFIP), which makes flood insurance available to any property in the city limits.  Flood insurance is recommended even if a property or house is not located within a mapped floodplain.   Properties located in a FEMA floodplain with a Federally-backed mortgage are required to carry flood insurance.   Littleton also participates in the Community Rating System (CRS) program which provides discounted flood insurance premiums for residents. 

Information about whether a property is located in a floodplain or has other flood risk, is available from the Public Works Department/Engineering staff.  Call 303-795-3865 to talk to the floodplain administrator.  The following information and assistance is available:

  • Potential flooding risk at a property.
  • FEMA floodplain and floodway maps, floodplain elevation information, and flood depths based on an address.
  • Urban Drainage and Flood Control District floodplain maps, elevations, and depths based on an address.
  • Flood insurance information.
  • Ways to help reduce flood risk at a property and financial assistance to do so.
  • Special flooding situations or history of flooding.
  • FEMA community number, map panel number, effective dates of the mapping, and the designated flood zone.
  • Whether the property is located in a special natural area that should be preserved; wetlands, valuable habitat, etc.

Stay informed and stay safe!
