The Federal Emergency Management Agency (FEMA) released new floodplain maps. Those revisions could impact some Treasure Valley residents.
The new maps cover parts of Ada and Canyon Counties.
The floodplain is an area that has a one percent chance of being inundated each year. The new maps chart areas facing the risk of being overrun with water along the Boise River, Nine Mile Creek and Willow Creek among others.
The Idaho Press Tribune reports the revised maps will be used for more than just making development and land use decisions. Residents could be impacted as the data will also be used to set flood insurance rates.
Ada and Canyon County residents who live in the floodplain can attend three open houses throughout the area between January 31 and February 2 for more information about the map revisions.
