The purpose of the Lyon County All Hazard Mitigation Plan (AHMP) is to determine how to reduce property damage and loss of life resulting from natural and manmade hazards. The Lyon County AHMP includes resources and information to assist county residents, public and private sector organizations, and others interested in participating in planning for both natural and manmade hazards. This mitigation plan identifies hazards that pose a threat to Lyon County, as well as what is currently being done to mitigate their impacts. The plan also provides a list of actions and programs that may enable Lyon County to further reduce negative impacts caused by disasters. The implementation strategies address both natural and manmade hazards that include but are not limited to flooding, drought, severe summer and winter storms, fires, and tornadoes.
