Information about FEMA's floodplain mapping activities that are currently underway in New Hampshire.
Risk MAP Program
FEMA’s current mapping program is Risk MAP (Mapping, Assessment and Planning). The goal of the Risk MAP program is to deliver quality flood hazard data and maps that increase public awareness about flooding and lead to action that reduces risk to life and property. To learn more about Risk MAP in New Hampshire, view the 2015 New Hampshire Risk MAP Business Plan.
FEMA Risk MAP Mapping Projects in New Hampshire:
The first step in a Risk MAP project is called the Discovery process. Discovery is used to help determine whether a mapping project is actually needed, and if so, what the scope of the project will be. Several Discovery projects have recently been completed and the following mapping projects are now underway:
- Winnipesaukee River Watershed - Updated flood analyses are being performed in Spring/Summer 2018. Updated maps will be developed once that work is complete.
- Nashua River Watershed - Updated flood analyses are expected to be completed later in 2018. Updated maps will be developed once that work is complete.
- Merrimack River Watershed - The development of revised flood maps is currently underway. Preliminary versions of the maps are expected to be issued in late 2018.
- Salmon Falls—Piscataqua Rivers Watershed (Inland) - Preliminary flood maps are currently expected to be issued in late 2018.
- Rockingham County Coastal Study: FEMA is finalizing the schedule for moving forward with the updated maps. It is expected they will become effective sometime in 2019.
