Do not re-route waters from your property to your neighbors or the street.
Floodwaters may carry raw sewage, chemical waste and other disease-spreading substances. If you've come in contact with floodwaters, wash your hands with soap and disinfected water.
Electric current passes easily through water, so stay away from downed power lines and electrical wires.

Floodplain Management

It's never too late to think about long term planning to prevent flood loss in the future, and to provide peace of mind when the snow pack starts to melt.

The City of Hailey has a Flood Hazard Overlay District, which includes all property that has been determined by the Federal Emergency Management Agency (FEMA) to be in the Special Flood Hazard Area. This zoning district has been set up to promote the public health, safety, and general welfare, and to minimize public and private losses due to flood conditions.

Resources

Flood Insurance

The City of Hailey participates in the National Flood Insurance Program, which assures that flood insurance is available to everyone in the City. This program is set up to help reduce the flood hazard and lower the cost of flood insurance within the city. If you live in the floodplain and do not have flood insurance, check with your insurance agent. A standard homeowner's insurance policy does not provide flood damage coverage. According to most insurance carriers in the area, a 30-day waiting period exists for flood insurance to be effective, so if you feel flooding in your neighborhood may impact you, make sure that you have your flood insurance in place ahead of time. The City of Hailey Floodplain Manager is available to assist with any technical questions you may have about flood insurance policies and coverage. Please call 788-9815, to find out more information

Floodplain Development Regulations

The City of Hailey regulates activities, which occur within the Flood Hazard Overlay District through Section 17.04J of the Zoning Title.

A Flood Hazard Development Permit is required prior to any development within the Special Flood Hazard Area (SFHA). This includes additions to existing buildings, any excavation or grading, the construction of new structures, fencing and stream alteration. Some projects may also require approval from the Idaho Department of Water Resources and the Army Corp of Engineers. If you are uncertain if your project would require a permit and/or prior approval, please contact the Floodplain Administrator or Building Departments prior to the commencement of any work.

Importance of Protecting Floodplain Resources

Floodplains provide many benefits and functions, which are valuable to our community. Simply put, a properly functioning floodplain helps reduce flood losses and erosion, improves water quality and wildlife habitat, and provides recreational and educational opportunities.

It is important to remember that even if you are not directly adjacent to the river or creek, your actions could impact the quality of the water. Storm water drains to the waterways and carries with it any pollutants it encounters along the way. Common pollutants, which seriously impact the water quality, include fertilizer, pesticides and oils.

Floodplain Determination

The main watercourses within Hailey are the Big Wood River, Indian Creek and Quigley Creek. If you live or own property near one of these waterways, you may be in the floodplain. FEMA produces a Flood Insurance Rate Map (FIRM), which is available for review at the City of Hailey. To find out where your property is in relation to the floodplain, contact the Floodplain Administrator at 208.788.9815 or visit the link below:
