Dry Creek Flood Control Project
On June 17, the Federal Emergency
Management Agency (FEMA) issued
new floodplain maps for Dry Creek
that reflect the $10 million Dry Creek
Flood Control Project constructed by
Fort Collins Utilities. Photos at right
show two of the 12 project components
that included both stormwater
detention and conveyance.

Insurance Recommended
When a structure is mapped out of the
floodplain, it is no longer subject to the
mandatory flood insurance purchase
requirement. Property owners should
give a copy of the new floodplain map
to their lender and insurance agent.
Policy holders also may be eligible for a
The risk for flooding still exists.
The Dry Creek project relies on
mechanical systems to control the flow
of flood water, and there is always a
risk of failure. Also, the majority of the
land that is no longer in the floodplain
is located below the Larimer and Weld
To get a copy of the new map:
Visit FEMA’s Web site at http://msc.fema.gov or
contact Fort Collins Utilities and ask for a floodplain determination.
You will receive a copy of the new map in three to five days.

irrigation canal. In the event of a
breach in this canal, much of the area
would experience flooding. While
many areas are no longer in the Dry
Creek floodplain, they are still
mapped in the Poudre River 500-year
floodplain. Also, localized drainage
problems may exist.
Given these risks, flood insurance is
still recommended. However,
because many areas are no longer in
the floodplain, the cost will be much
less. Property owners should ask their
insurance agent about a Preferred Risk
Policy that combines structural
coverage with contents coverage.
Nationwide, 30 percent of flood
insurance claims come from areas
outside the mapped floodplain.
