Coastal Resilience Initiative

How do we protect our historic City and avoid future property damage? Good news: Portsmouth was one of five communities selected for a pilot program with $30,000 in funding from the Gulf of Maine Council, through a grant from the National Oceanic and Atmospheric Administration (NOAA). This grant funded a research study, The "Coastal Resilience Initiative" prepared for the City by a team of researchers from the University of New Hampshire and the Rockingham Planning Commission.
