HAMPTON — Scientists have created a tool to help homeowners learn more about the longevity of their Seacoast property.

The Union of Concerned Scientists projections indicate that 1,875 homes in New Hampshire are at risk of becoming chronically inundated with water from rising sea levels and increased tidal flooding by 2045.

The Union of Concerned Scientists has just released the tool publicly; it is based on property data.

The scientists say in Hampton, 1,498 homes are at risk of being chronically inundated with sea water by 2045. This represents nearly 16 percent of the housing units in the Hampton community.

According to the tool, the homes are worth a collective $424,531,841 and contribute $6,281,168 to the local property tax base.

A news release issued by the Union of Concerned Scientists says Rye is also projected to be affected, with nearly 200 homes at risk in the same time frame.

Senior Analyst Erika Spanger-Siegfried said property owners need to assess their risk.

“If they are not experiencing any high-tide flooding now, using online tools such as our interactive maps can help individuals understand whether — and if so, when — chronic flooding from sea level rise will be an issue for their community in the coming decades,” Spanger-Siegfried said.

For some, elevating electrical equipment or the home itself may be enough. But if a home is elevated and surrounded properties and roads are flooding during high tides, the problem isn’t solved, she said.

According to the news release, accelerating sea level rise driven by climate change is projected to worsen tidal flooding in the United States, putting as many as 311,000 coastal homes in the lower 48 states with a collective market value of about $120 billion in today’s dollars at risk of chronic flooding within the next 30 years.
