Repetitive Flood Outreach

The City and County of Denver participates in the National Flood Insurance Program’s Community Rating System, which enhances education and outreach to residents regarding flood risks. Each year, we send letters to property owners and tenants who live near properties that have received repetitive flood insurance payouts from FEMA so they can be aware of the potential for flooding in their areas.

If you received a letter about potential flood risk, use the links on this page to find the resources you need to protect yourself and your property.


Check with the Denver Department of Transportation and Infrastructure Engineering Division on the extent of flooding in your area. Our engineers can answer questions and provide additional information.

For general flood risk information such as causes of repetitive flooding, flood depths, appropriate flood protection levels, and flood protection alternatives:

For questions about development requirements or construction permits:

Prepare your family and/or business. Go to for detailed information on how to:

  • Make an emergency plan for personal and family preparedness.
  • Make a business emergency plan.
  • Download and use the appropriate emergency preparedness checklists.

Know how to shut off the electricity and gas to your property when a flood occurs.

Make a list of emergency numbers and identify a safe meeting place. Communicate the plan with your family.

Inventory your building and its contents. This is useful when filing insurance claims.

Put insurance policies, valuable papers, medicine, etc. in a safe place.

Keep valuables up off the basement floor and garage floor, preferably on a higher level that is unlikely to incur flood damage.

Collect and put cleaning supplies, camera, waterproof boots, etc. in a handy place.


Consider some permanent flood protection measures.

  • Mark your fuse or breaker box to show the circuits located in areas most vulnerable to flooding. Turning off the power can reduce property damage and save lives. 
  • Consider elevating or floodproofing your building and utilities above flood levels. 
  • Check your building for, and consider protecting, water entry points such as doors and window wells. 
  • Install a floor drain plug, standpipe, overhead sewer, or sewer backup valve to prevent sewer backup flooding. 


Be aware that some flood protection measures may need a building permit and other flood protection measures may not be safe for your type of structure, so be sure to check with the City & County of Denver Development Services.

For more information on floodproofing or flood protection alternatives, contact Kevin Lewis at or 303-446-3658.

Consider a flood insurance policy. It will help pay for repairs after a flood and, in some cases, it will help pay the costs of elevating a substantially damaged building.

The areas NOT mapped by FEMA as a designated Special Flood Hazard Area may qualify for a lower-cost Preferred Risk Policy.

Most homeowner’s insurance policies do NOT cover damage from floods. Due to the flooding that happens in your area, there could be more damage to the furniture and contents than there is to the structure. Be sure you have contents coverage.

Do not wait for the next flood to buy flood insurance protection. In most cases, there is a 30-day waiting period before flood insurance coverage takes effect.
