FIRM Revision Project

The Town of Amherst has hired AECOM to revise Amherst's Flood Insurance Rate Maps (FIRM). This the goal of this project is to produce and officially certify with FEMA a greatly improved FIRM, providing property owners with a more fair representation of flood probability. 

Draft FIRM maps were made available in July, 2016, and were publicly unveiled at a joint meeting of the Planning Board and Conservation Commission on July 19th, 2016. Resources below include presentations, draft maps and an interactive comparison map:
