In 2006, Lake County and participating Lake County municipalities developed and adopted the first Lake County Countywide All Natural Hazards Mitigation Plan (ANHMP). The Federal Emergency Management Agency (FEMA) requires that a community develop and adopt a FEMA-approved ANHMP in order to be eligible for hazard mitigation grant funds. This ANHMP is required to be updated and re-adopted every five years to maintain grant eligibility.
Lake County Stormwater's 2022 ANHMP is the third update for the 2006 ANHMP. This plan is multi-jurisdictional, meaning the County and its municipalities must adopt the ANHMP. The mitigation plan identifies activities and projects to reduce the damages caused by natural hazards such as tornadoes, floods, and severe summer and winter storms. Annual ANHMP reports are published yearly.
