Wyoming Region 6 Hazard Mitigation Plan - Public Review Draft
Washakie, Hot Springs, Park and Big Horn Counties

This plan is the product of a 2021 planning process undertaken by the four counties in the Big Horn Basin in Wyoming Region 6 – Big Horn, Park, Hot Springs and Washakie. The purpose is to meet the requirements of the Disaster Mitigation Act of 2000 (PL 106-390), and thereby maintain continued eligibility for certain Hazard Mitigation – or disaster loss reduction – programs from the Federal Emergency Management Agency (FEMA). This plan updates the 2016 Region 6 Hazard Mitigation Plan including each county annex for Big Horn, Hot Springs, Washakie and Park counties and sets priorities for mitigation in the Region for the time period of 2022-2027.
