In response to the requirements of the Disaster Mitigation Act of 2000 (DMA 2000), Lewis and Clark County, the City of Helena and the City of East Helena, have developed this Multi-Jurisdictional Pre-Disaster Mitigation (PDM) Plan. DMA 2000 amends the Stafford Act and is designed to improve planning for, response to, and recovery from, disasters by requiring State and local entities to implement pre-disaster mitigation planning and develop PDM Plans. The Federal Emergency Management Agency (FEMA) has issued guidelines for development of PDM Plans. The Montana Disaster and Emergency Services (DES) supports plan development for jurisdictions in the State of Montana. 

Lewis and Clark County completed and adopted a PDM Plan in 2005, which was updated in 2011, to help guide and focus hazardmitigation activities. The County,working togetherwith Tetra Tech Inc., has prepared this 2017 update to their PDMPlan to satisfy the requirement that PDMPlans be updated every five years. The 2017 Lewis and Clark County PDM Plan profiles significant hazards to the community and identifies mitigation projects that can reduce those impacts. The purpose of the updated PDM Plan is to promote sound public policy designed to protect residents, critical facilities, infrastructure, private property, and the environment from natural and man-made hazards. The updated Lewis and Clark County PDM Plan includes resources and information to assist residents, organizations, local government, and others interested in participating in planning for natural and man-made hazards. This 2017 updated PDM Plan supersedes the 2005 and 2011 PDM Plans.
