8-Floodplain Study


From 2013 to 2014, Urban Drainage and Flood Control District (UDFCD) and Federal Emergency Management Agency (FEMA) began a cooperative effort to get a number of locally developed Flood Hazard Area Delineation (FHAD) studies incorporated into the FEMA Flood Insurance Rate Maps (FIRMs).  A Risk Mapping Assessment and Planning (Risk MAP) project that used the Physical Map Revision (PMR) process would revise the FIRMs.  The FHADs had been produced to identify and update flood risk potential and floodplain boundaries.

The 8-Floodplain Study region consists of eight drainage basins that include the following streams:

  • Happy Canyon Creek
  • Badger Gulch
  • Green Acres Tributary
  • Sand Creek (Colfax to Yale)
  • Lower Coal Creek (Downstream of Yale)
  • Lower Murphy Creek (Downstream of Alameda)
  • Senac Creek (Downstream of Aurora Reservoir)
  • Toll Gate Creek
  • Lower East Toll Gate Creek (Downstream of Hampden)
  • West Toll Gate Creek
  • Unnamed Creek
  • Cherry Creek (Downstream of Cherry Creek Dam)
  • Littles Creek
  • Marston Lake North Drainageway

Getting the FHAD information on the FIRMs help residents and business owners make informed decisions about personal safety and protecting financial assets. Having current flood mapping also allows community planners, local officials, engineers, builders and others to make determinations about where and how new structures, subdivisions, developments, and redevelopments should be built to reduce risk of flood damage.

Preliminary Flood Insurance Rate Maps (FIRMs) for the 8-Floodplain Study PMR project are now available.

Here is a list of materials that can help you learn more about the studies and their potential impact on your property. You can also view proposed flood mapping changes with this link.
