Connecticut residents and businesses can now assess their property’s vulnerability to floods, wildfires, hurricane winds and extreme heat using a free online mapping tool launched Monday by Gov. Ned Lamont and state Insurance Commissioner Andrew N. Mais.
The tool, developed in partnership with the state Insurance Department and First Street, a global climate-risk data firm, provides property-specific assessments using interactive maps and risk-rating reports. By entering an address, homeowners and businesses can see how their property might be affected by a range of climate-related threats.
“This is an important piece in our statewide commitment to build resilience throughout Connecticut communities,” Lamont said in a statement, adding that it is also an example of his administration “leveraging effective public-private partnerships to help our residents and businesses.”
Connecticut is the first state to make the tool available to all residents. The launch comes more than a year after record rainfall and severe flooding in August 2024 that left many property owners with costly damage but no flood insurance.
“Many of the affected property owners did not have flood insurance because they did not believe they were at risk,” Mais said. “Homeowner’s insurance policies traditionally do not cover flood damage, yet nearly half of all flood damage occurs outside FEMA-designated flood zones.”
Mais said First Street’s technology offers more detailed, forward-looking models than traditional FEMA maps, projecting risks decades into the future.
First Street Founder and CEO Matthew Eby said the goal is to provide residents with science-based data to make “smarter, more informed decisions about insurance, preparedness, and long-term resilience.”
