Laura Lageman's 1835 farmhouse in Woodbury sat on the market for months. The house had an accepted offer. Then the buyer walked, and Lageman was left puzzled. "We accepted an offer, but for no reason, they backed out," she told Insurance Journal. Her home sits outside FEMA's official high-risk flood zone. It still carries a 9-out-of-10 flood risk score from a private modeling firm called First Street, a number that has nothing to do with any federal map and everything to do with why that buyer got cold feet.
Woodbury is landlocked, nowhere near the coast. Branford is not. The town's shoreline runs through Stony Creek, Pine Orchard, Indian Neck, and Short Beach, and its inland edge wraps around Lake Saltonstall, the reservoir that shows up on the town's own GIS maps as one of its defining natural features. If a private flood score can unravel a deal on a farmhouse two counties from the water, it is worth understanding exactly what changed here on July 1, because the mechanism behind that Woodbury story is now written into Connecticut law and live in every transaction closing this summer.
What Public Act 25-33 Actually Requires
Connecticut's Public Act 25-33 rewrites what happens at three separate points in a residential transaction, and the obligations do not all land on the same party.
| Who | What they must disclose | When |
|---|---|---|
| Sellers and landlords | A new Flood Risk Awareness section on the residential property condition report, covering FEMA zone, flood history, and elevation certificates | Required since July 1, 2026 |
| Mortgage lenders | Written notice that standard homeowners insurance does not cover flood damage, and that flood damage can occur regardless of flood zone | No later than 10 days before closing, required since July 1, 2026 |
| Insurers | Plain-language notice in homeowners and renters policies stating floods are not covered and explaining how to buy separate flood coverage | Insurers were instructed to comply starting in mid-2025, ahead of the rest of the statute |
None of this was a suggestion, and none of it is optional now that the statute is live. The lender requirement in particular has teeth: a creditor has to put the flood warning in writing, in the applicant's hands, within ten days of the closing table. For a Branford buyer used to thinking of flood risk as something that only matters if the deed mentions a bulkhead or a seawall, that ten-day window is where the surprise usually lands, and it is already landing on deals closing this month.
The Score Nobody Voted For
Here is where the law gets more interesting than a paperwork update. Connecticut did not just mandate disclosure of the official FEMA zone. It also partnered with First Street Technologies to launch a public portal that scores flood risk on its own one-to-ten scale, using rainfall and localized flooding models that go beyond what FEMA maps capture. The state built this because FEMA's own numbers admit a gap: on average, 40 percent of the claims paid out under the National Flood Insurance Program come from properties sitting outside the official high-risk zones. FEMA's maps were built to model storm surge and river overflow. They were never built to model what happens when six inches of rain falls in an afternoon on a street that has never flooded before.
That gap is exactly what caught Lageman's buyer off guard, and it is exactly what could catch a Branford seller off guard too, especially anyone whose property sits near a brook, a low spot, or a stretch of road that already floods during a nor'easter even though the FEMA panel says the parcel is fine. The disclosure law surfaces the official zone. The First Street portal, available to any buyer with an internet connection, surfaces a second number that can say something entirely different.
Not everyone in the industry is comfortable with that second number carrying so much weight. Alexander Chingas, a Coldwell Banker agent in Westport, put it plainly to Insurance Journal:
some people don't look at the tools as a starting point but rather view them as final and absolute
That tension already played out publicly. Zillow pulled First Street scores from its listings last year after a couple in Chappaqua, New York sued over a 9-out-of-10 rating on a home outside any official flood zone, arguing the score damaged their property's value. As of early 2026, the case was still awaiting a ruling. Whatever the outcome, the underlying dynamic will not disappear from Connecticut transactions. The state built its own version of that scoring tool and put it in front of every buyer.
The Map Underneath the Map Is Also Moving
Layered on top of the new disclosure rules is a separate process that has been quietly running since last year. New Haven County's FEMA flood maps entered their public appeal window in April 2025, meaning the zone lines property owners have relied on for years are being redrawn right now. A parcel that reads as Zone X today, low risk, no mandatory insurance, can end up reclassified as Zone AE by the time a preliminary map becomes final. When that happens, a lender will require flood insurance on a property that never carried it before, regardless of what the seller's disclosure said six months earlier.
This is the part that catches transactions between contract and closing. A buyer who ran their numbers based on a property's current zone designation could find their lender requiring a policy that did not exist in the underwriting conversation, simply because the map moved underneath the deal.
Why This Is Not Just a Waterfront Problem
It is easy to assume flood disclosure only matters for the handful of Branford streets that touch Long Island Sound directly. The town's own regulatory structure suggests otherwise. Branford's floodplain rules are written into Chapter 161 of the town code, administered by the Town Engineer with reference to FEMA's Flood Insurance Rate Maps, and the Flood and Erosion Control Board exists specifically to hear appeals when a property owner disputes how those maps apply to their land. That board would not need to exist if flood exposure in Branford started and ended at the waterline.
The town has also built its own tool for tracking flooding that has nothing to do with the official maps at all. The Coastal Vulnerability Working Group runs a community reporting project through mycoast.org, collecting resident-submitted photos of tidal and storm-related flooding on Branford's roads, the kind of nuisance flooding that shows up during a routine high tide or a heavy rain event and never appears on a FEMA panel because it is not the storm surge or river overflow those maps were built to capture. That is the same category of localized flooding First Street's model is designed to catch and FEMA's is not.
Add Lake Saltonstall to that picture, an inland reservoir sitting well back from the shoreline, and the argument that flood exposure is a coastal-only conversation gets harder to make. A property near the lake, or along one of the brooks that feed it, can carry real flood history that has nothing to do with its distance from the Sound.
The Insurance Math Was Already Changing
Even without the new disclosure law, the cost side of this conversation was shifting. Under FEMA's Risk Rating 2.0 framework, primary residence flood premiums can climb by up to 18 percent per year until each policy reaches its calculated full-risk price. A seller's current flood premium, quoted in good faith on the disclosure form, may not reflect what a buyer will actually pay in year two or three of ownership if that policy is still on the glide path upward.
There is also a nearer deadline worth watching if you are closing this fall. The National Flood Insurance Program's federal authorization currently runs through September 30, 2026. If Congress does not act by then, FEMA would stop issuing new or renewal policies, though existing policies and claims would continue uninterrupted. Private flood insurance, sold through carriers separate from NFIP, would be unaffected by any lapse. For a buyer who needs a brand-new flood policy to satisfy a lender in the weeks around that date, it is a real enough possibility to ask about before signing a contract, not after.
A Few Questions Worth Asking Before You List or Offer
Does the new disclosure law apply to condos? The statute modifies the residential property condition report used across one-to-four unit transfers, and the same flood zone and history questions extend to that form regardless of property type.
If my FEMA zone hasn't changed, do I still need to worry about the First Street score? Yes. The two numbers are produced by entirely different methods, and a buyer researching a Branford address can see the First Street score whether or not it appears on your disclosure form.
What happens if the NFIP lapses while I'm under contract this fall? Existing policies and claims continue as normal. The risk is narrower: a buyer who needs a new policy issued between a lapse and a Congressional fix could face a delay, though private flood insurance remains available in the meantime.
Can I appeal a First Street score the way I could appeal a FEMA zone determination? FEMA zone disputes go through an established process, including Branford's own Flood and Erosion Control Board. First Street's model is privately run, and no equivalent formal appeal exists yet, which is part of why the score has drawn scrutiny from agents and homeowners alike.
None of this means a Branford sale is harder to close than it was last year. It means the paperwork now says out loud what used to live in a buyer's private search history. If you are weighing a sale in Stony Creek, Pine Orchard, Indian Neck, Short Beach, or anywhere in between, it is worth knowing what your property's disclosure will show before a buyer sees it for the first time.
