Hazard Mitigation
Pre-Disaster Mitigation

Pre-Disaster Mitigation (PDM) provides funds to states, territories, Indian tribal governments, and communities for hazard mitigation planning and the implementation of mitigation projects prior to a disaster event.

Funding these plans and projects reduces overall risks to the population and structures, while also reducing reliance on funding from actual disaster declarations. PDM grants are to be awarded on a competitive basis and in addition to the amount allocated by the State of New Hampshire.

New Hampshire has historically utilized Pre-Disaster Mitigation (PDM) funds in a number of ways. Many of the local hazard mitigation plans developed by communities across the state are funded leveraging PDM funds. Additionally, PDM funds can be used to fund other projects that involve inter-agency collaboration to increase the benefits of mitigation actions. A project in conjunction with the Department of Environmental Services has allowed New Hampshire to study and predict fluvial erosion in the Souhegan watershed. Fluvial erosion is a process that occurs as rivers move laterally within their floodplains, which is a natural process that typically occurs during floods. Many developed areas in New Hampshire lie within river floodplains. This project will allow New Hampshire to continue to address the risks posed to citizens by river and erosion hazards throughout the state, including the incorporation of date into hazard mitigation plans.
