Floodplain Program

The City of Brighton Utilities Department's Floodplain Program is dedicated to minimize the loss of life and property that is associated with flooding events, and providing residents with a safe environment to live, work, and play.

Flood Safety Tips

  • Learn the safest route from your property to higher, safer ground, but stay tuned to reports of changing flood conditions.
  • Do not walk through flowing water. Currents can be deceptive, and 6 inches of moving water can knock you off your feet.
  • Do not drive through a flooded area.
  • If there is an evacuation notice, leave your home and go immediately to a safe shelter, hotel, or relative's house.
  • Turn off all utilities, gas, and electricity at the main switch. Stay away from power lines and electrical lines.

 Flood Insurance

Brighton participates in the National Flood Insurance Program (NFIP) which means that federally subsidized flood insurance is available to everyone in the city, regardless of location and past damage. Basic homeowner's insurance does not cover damage from floods. Don't wait, you can act now to protect your property from flood damage. Because of Brighton's susceptibility to intense rainfall events, even areas outside of the mapped floodplain may experience flooding. Contact the NFIP, or call your insurance agent.

Development Requirements

All development in the Brighton floodplain requires a Floodplain Permit and is subject to the City of Brighton Floodplain Regulations. Development includes, but is not limited to, all new construction, filling, grading, and paving. Any development in the floodplain without a floodplain permit is illegal, and such activity should be reported to the Floodplain Administrator.

Storm Drainage System Maintenance

Street flooding is often the result of storm drain inlets that are too small to handle heavy runoff In other cases, the drain may need cleaning. The City performs routine maintenance of the municipal storm sewer system to reduce flooding and remove pollutants. Report blocked inlets or storm sewer maintenance needs to the Stormwater Division.

Illegal Dumping

Flooding may also be cause by illegal dumping of debris. It is illegal in Brighton to dump any type of debris into a stream, drainage ditch or storm sewer. Citizens should do their part to keep ditches, inlets and channels free of debris, grass clippings, oil, and other contaminants. Report illegal dumping to the Stormwater Hotline at 303-655-2120.

Lot-to-lot Drainage and Lot Grading

A drainage problem within your lot or water running from lot-to-lot is considered to be a civil matter and is not regulated by the City of Brighton. Contact an engineer or landscape professional to assist you in solving these matters.
