Connecticut Launches Free Online Property Risk Mapping Tool

October 8, 2025

Connecticut has launched a free online risk mapping tool that allows Connecticut homeowners and businesses to assess their property’s risk from flooding, wildfires, and other perils to better understand their insurance needs.

Provided through a public-partnership between the state insurance department and First Street, a provider of physical climate risk data and analytics, the mapping tool gives residents access to property-level data through interactive maps and risk-rating reports.

By entering an address, homeowners and businesses can immediately see their property’s exposure to a range of climate-related risks such as flooding, wildfire, hurricane winds, extreme heat and air quality.

Connecticut. says it is the first state to make this mapping tool available to all its residents.

According to Insurance Commissioner Andrew Mais, the need for such a risk assessment tool was evidenced by the catastrophic flooding experienced in parts of western Connecticut during a major rainfall in August 2024. “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 tool is a “marked improvement” over the static federal government’s FEMA flood maps.

“With natural disasters on the rise, we want to help people make smarter, more informed decisions about insurance, preparedness, and long-term resilience,” said Matthew Eby, founder and CEO of First Street “The way to make that happen is by offering them science-backed, peer-reviewed data about their exposure.”

The tool can be accessed by visiting portal.ct.gov/cid/resource-library/free-climate-risk-mapping-tool. It can also be accessed through the Flood Insurance Information Center page of the Connecticut Insurance Department website.
