Flood risk in Westport is not only a waterfront question. The Sept. 13 storm, which dropped about seven inches of rain, flooded streets around Compo and downtown and damaged the Jesup Road bridge, well away from the beach. A buyer needs to check two kinds of risk, coastal surge and inland stream flooding, and to check them before the offer, not after the inspection.
Where the risk is
Westport’s 2021 hazard mitigation plan names Saugatuck Shores, Canal Road, Compo and Hale Court as flood-prone coastal areas. It names the Saugatuck River, Muddy Brook, Dead Man Brook and the Aspetuck River as stream corridors with flooding problems. The same plan counted 213 repetitive-loss properties in town, meaning properties with multiple flood insurance claims, and 187 of them were in the 1 percent annual chance flood zone, often called the 100-year floodplain.
Roughly 3,000 Westport properties lie in mapped flood zones, according to a 2023 Westport Journal report.
The maps are changing
FEMA has restudied the Saugatuck River watershed, and the town says the revised maps are expected to be adopted this fall. Twelve map panels change, numbers 0392, 0394, 0403, 0404, 0411, 0412, 0413, 0414, 0416, 0418, 0551 and 0552. The appeal period for the new maps ran from Feb. 16 to May 16, 2024, and has closed.
When the new maps take effect, some properties will move into a special flood hazard area and others will move out. If you are buying near the river or its tributaries, ask your attorney and lender which map they are using, and look at both.
How to check an address
- Go to the FEMA Flood Map Service Center at msc.fema.gov and search the address.
- Print a FIRMette, FEMA’s one-page excerpt of the official map. Preliminary maps cannot produce a FIRMette, so for the pending Saugatuck maps you will need the preliminary data or the town’s floodplain page.
- Ask the seller for the Residential Property Condition Report. The version Connecticut has used since July 2025 asks about floodplain status, past flood insurance claims, federal disaster aid and water penetration.
- Ask for an elevation certificate if the house is in a flood zone. It records the height of the lowest floor relative to the base flood elevation, which drives the insurance premium.
- Get a flood insurance quote before you finalize the offer, not after.
What insurance will cost
FEMA prices National Flood Insurance Program policies under Risk Rating 2.0, which has applied to all policies since April 2022. It weighs flood frequency, the types of flooding a property faces, its distance to water, the height of the first floor and the cost to rebuild. For existing policies, most annual increases are capped at 18 percent. If you take over the seller’s policy, ask how far its premium is from the full-risk price, because the cap means it may still be climbing.
Westport’s participation in FEMA’s Community Rating System at Class 8 gives policyholders a 10 percent discount. And since July 1, 2026, every Connecticut homeowners, renters and condominium policy must state plainly that flood is not covered and that separate flood insurance is available.
What you can build
Buyers planning a renovation or a new house in a flood zone face added rules. The town’s 2021 hazard plan describes a minimum elevation standard that includes one foot of freeboard above base flood elevation. Confirm the current requirement with Planning and Zoning. Large renovations can trigger the substantial improvement rule, which requires bringing the whole house up to flood standards.
Since Oct. 1, 2025, all new single-family houses inside Connecticut’s coastal boundary need coastal site plan approval under Public Act 25-33, and plans in flood hazard areas are referred to the state Department of Energy and Environmental Protection. Work waterward of the coastal jurisdiction line, including docks, seawalls and fill, needs a state permit. The coastal boundary runs at least 1,000 feet inland from the water, and farther where tidal wetlands or the 1 percent flood zone reach inland.
In March, Planning and Zoning received a proposal, Text Amendment 866, that would allow up to five additional feet of building height in flood zones when the first floor is at or above base flood elevation. Ask the town whether it was adopted.
The beaches
The town is weighing a $14.1 million to $54.5 million plan to restore five town beaches. Wider beaches can buffer the roads and parking lots behind them, but beach work does not change a flood map or a premium.
