OOB, ME Flood Zones: New FIRMs, 2024 Storm

The FIRM Update: Maps That Hadn't Changed Since the 1980s

Old Orchard Beach's Flood Insurance Rate Maps dated from 1984-85, and the town's floodplain-management ordinance hadn't been updated since 1986, according to the town's own FEMA flood-maps page (oobmaine.com/department/fema-flood-maps/). That's roughly four decades of sea-level, storm-pattern, and coastal-development change sitting behind a set of maps that predated most of it.

FEMA sent a letter dated January 17, 2024, declaring its updated flood-hazard determinations for the town "final," which started a clock: OOB had to adopt new FIRMs and a new floodplain-management ordinance by July 17, 2024, to remain in the National Flood Insurance Program. Losing NFIP standing would have meant federally backed flood insurance stops being available in town, a real threat for a town where a large share of the housing stock is at or near sea level.

The Town Appealed, and the Appeal Worked

Before adopting the new maps, Old Orchard Beach appealed FEMA's initial proposal, and the appeal succeeded to some degree: the final maps reflect a reduction in the extent of some regulated flood zones and lower base flood elevations in certain areas compared with what FEMA first proposed. In practical terms, fewer properties ended up newly regulated than the initial draft maps would have caught.

That's a meaningfully different outcome than simply accepting FEMA's first pass, and it's worth knowing if you're evaluating a property near the edge of a mapped flood zone: the boundary you'd be checking today already reflects a town-initiated correction, not FEMA's original line. It doesn't tell you where that boundary actually sits for any specific parcel, though, and this research did not obtain a zone-by-zone or parcel-level breakdown of which properties moved in or out of a regulated zone as a result of the appeal.

A Separate Story: The January 2024 Storm and the Goosefare Brook Breach

Independent of the map update, a multi-day storm event from January 9-13, 2024, sent storm surge through an eroded dune near Goosefare Brook, flooding more than 75 homes in the Ocean Park neighborhood, with some houses taking on four feet of water. Town Manager Diana Asanza was quoted at the time saying the dunes "protected hundreds of homes and businesses from more severe flooding," meaning the damage would have been considerably worse without the dune system that ultimately failed at that one point.

Ocean Park is a historic neighborhood in its own right, founded in 1880-81 by Free Will Baptist leaders as a Chautauqua-style religious and educational retreat, distinct in character from the boardwalk-and-amusement-pier core of town most visitors picture. That it was Ocean Park's dune line, specifically, that gave way in the Goosefare Brook breach is a real, sourced fact worth knowing if you're looking at property in that part of town; the neighborhood's fuller history is its own subject, not a flood-zone one.

The storm's scale was serious enough that President Biden issued Major Disaster Declaration ME-4764-DR on March 20, 2024, covering eight Maine counties including York County and unlocking FEMA's Individuals and Households Program and related federal recovery assistance, processed through DisasterAssistance.gov and York County Disaster Recovery Centers.

The Dune Rebuild: Two Phases, Not a Permanent Fix

In direct response to the January 2024 breach, the town has a dune-restoration effort underway costing more than $1 million, funded primarily through federal and state disaster assistance, split into two phases. Phase 1, at Goosefare Brook, began the week of January 13, 2026, placing 1,400 cubic yards of sand across 400 feet of beach to rebuild the dune that failed. Phase 2 followed the next week, covering the northern beach section more than half a mile north of the Pier, placing 4,500 cubic yards of sand sourced from a Dayton, Maine quarry, plus sea-grass planting for stabilization.

Town officials have been explicit that this isn't a permanent solution. Per the reporting on the project, more sand will need to be brought in or dredged as sea levels continue to rise, and the town is explicitly preparing for the possibility of a 100-year flood event, not just a repeat of January 2024. Anyone weighing a purchase near Goosefare Brook or Ocean Park on the strength of this rebuild should read it as real, current mitigation, not a guarantee against a future breach.

What This Research Could Not Confirm

No parcel-level or zone-by-zone breakdown of FEMA VE (coastal high-hazard, wave-action) versus AE (standard 100-year floodplain) designations for Old Orchard Beach was confirmed in this research, before or after the 2024 map update and the town's successful appeal. Treat any specific zone-letter claim about an individual OOB address as unconfirmed until you check it directly against the sources below, not against anything general stated on this page.

Separately, no historical hurricane-specific damage account for Old Orchard Beach, such as the 1938 Great New England Hurricane or 1991's Hurricane Bob, was found and confirmed this session. The January 2024 winter-storm sequence, not a hurricane, remains the strongest current, sourced storm-damage narrative available for the town, and it shouldn't be stretched to imply a documented hurricane history that this research didn't find.

It's also worth keeping OOB's geography in mind when thinking about flood exposure generally: the town covers 22.53 square miles total, but only 7.43 square miles of that is land, with the rest water, on the inner curve of Saco Bay. The beach itself is part of a roughly 7-mile regional sand system that continues into Scarborough to the north and Saco to the south, not a stretch of shoreline unique to OOB, which matters if you're comparing erosion or dune conditions across town lines rather than within them.

How to Check a Specific OOB Parcel

None of the general FIRM-update history, the January 2024 storm account, or the dune-rebuild details above substitute for a parcel-specific flood-zone determination. Go directly to FEMA's Flood Map Service Center (msc.fema.gov), enter the property address, and pull the current effective Flood Insurance Rate Map panel for that parcel.

Old Orchard Beach also maintains its own FEMA flood-maps page (oobmaine.com/department/fema-flood-maps/), which is the right place to start for town-specific context on the 2024 map adoption and the current floodplain-management ordinance. From there, confirm any elevation certificate, construction, or floodplain-management requirement with the town directly, and talk with an OOB-familiar insurance agent about NFIP premium costs before signing a purchase contract, not after.
