Beach Erosion Reality: Seaside, Florida
Seaside doesn't carry Florida's critically eroded designation on its own frontage, but two of its immediate neighbors do, and the county-wide numbers behind that fact have been getting worse, not better. Here's what the state's own erosion accounting, the renourishment project Seaside is already part of, and a major 2025 change to beach-access law actually mean for someone buying here.
Seaside's Spot on the Critically Eroded Map: Between Two Named Segments
The Florida Department of Environmental Protection maintains the state's official inventory of critically eroded shoreline, the Critically Eroded Beaches report, which qualifies segments for state and federal restoration cost-share. In its August 2024 edition, Walton County's critically eroded total stood at 18.8 of the county's roughly 26 miles of Gulf coastline, spread across five named segments. Seaside itself does not appear as a separately named segment on that list. What does appear, on either side of it, is the segment running through Gulf Trace and Grayton Beach immediately to Seaside's west, and the segment running through Seagrove Beach immediately to its east. Seaside sits in the gap between two officially eroded stretches, not inside one, at least as of FDEP's last published survey cycle.
That gap is worth reading carefully rather than optimistically. Erosion classifications shift between report editions as storms and longshore sand movement redraw the coast, and a stretch that tests clean in one cycle can be added to the list in the next. There's also a longer trend worth knowing: the Army Corps of Engineers' 2012 feasibility report for Walton County put the county's critically eroded total at 11.9 miles, roughly 45% of the county's Gulf frontage at the time. FDEP's own more recent count of 18.8 miles is roughly 58% more mileage than that 2012 baseline covered, over the twelve years between the two reports. Whatever the exact current line is, the direction is toward more of the county's coastline qualifying, not less. Anyone evaluating a specific Seaside lot should ask FDEP or Walton County's coastal resource office directly whether that address falls inside a mapped critical erosion area today, rather than assuming the gap holds.
A Number in the News, and Whether It Holds Up: the "73%" Figure
At the June 24, 2025 signing of Senate Bill 1622 in Santa Rosa Beach, held in Walton County itself, FDEP Secretary Alexis Lambert was reported as stating that roughly 19 of the county's 26 miles of Gulf beach, about 73%, were critically eroded and in need of nourishment. That figure got picked up in real-estate-adjacent coverage as a standalone statistic, but on its own it traces to one official's remarks at one event, not a citable report page.
It does, however, land close to a real, independently published number: FDEP's own Critically Eroded Beaches report (August 2024 edition) separately puts the county's total at 18.8 of about 26 miles, using named segments rather than a summary line. Nineteen miles and 18.8 miles are close enough to describe the same underlying picture, and a shift from one report edition to a later official's remarks a few months on isn't surprising. That said, this page could not independently re-pull FDEP's source PDF in this research pass to confirm which edition Secretary Lambert was citing, so treat "about three-quarters of Walton County's Gulf beach" as the right order of magnitude for the county as a whole, not a precise, freshly reconfirmed statistic, and don't extend it to mean three-quarters of Seaside's specific frontage, which the county figure doesn't break out.
The Renourishment Project Seaside Is Already Part Of
Seaside's beach isn't a standalone erosion case. It falls inside Study Reach 5 of the single, county-wide Hurricane Storm Damage Reduction project Walton County has pursued with the U.S. Army Corps of Engineers since the mid-2000s: the Corps' 2012 feasibility report maps that reach across FDEP reference monuments R-78 through R-127, running from WaterColor through Seaside, Seagrove Beach, WaterSound, Seacrest Beach, and on to Rosemary Beach and Inlet Beach. Seaside's own public beach access point corresponds to monument R-81, near the western end of that reach — roughly 46 monuments, and several miles, west of where the reach ends near Inlet Beach (R-127).
The project has a long, stop-and-start history. Walton County commissioners tabled it in March 2016 after too few beachfront owners granted the easements the Corps needed, then revived it in 2022 under a cost-share estimated at roughly 50% county, 20% state, and 30% federal for a first sand placement projected around $62 million. As of mid-2026, county officials describe the project as still in the survey and design phase: topographic and hydrographic surveys were completed in the first half of 2026, with a revised design plan expected in fall 2027 and a final design targeted for May 2028, per Walton County's environmental management office. That means Seaside's stretch is formally slated for renourishment, but on a design timeline running years out, not sand landing on any predictable near-term schedule. Confirm current status with Walton County's coastal resource office before assuming either an imminent fix or a permanently stalled one.
How the County Actually Pays for This: Tourist Development Tax Dollars
Renourishment isn't only a federal cost-share question; it's also funded locally. Walton County collects a 5% Tourist Development Tax (TDT) on short-term rentals, administered through the Walton County Clerk's office, and the county's own published TDT breakdown dedicates 1 full percentage point of that 5% specifically to beach nourishment and restoration, alongside separate shares for marketing, shoulder-season promotion, and public beach-access infrastructure. In practical terms, every short-term rental stay booked anywhere in the county, including in Seaside itself, contributes directly to the same nourishment funding stream backing the Study Reach 5 project.
That's a real, ongoing local funding source, and it's one more competitors covering Seaside rarely mention, but it isn't a substitute for the federal cost-share dollars the county-wide Corps project depends on for large-scale sand placement. A buyer weighing how nourishment gets paid for here should understand both halves: TDT revenue as a standing local mechanism, and the multi-year, multi-agency Corps project as the larger structural fix still working through design. Current TDT rates, collection totals, and allocation splits are public record through the Walton County Clerk of Courts and worth checking directly for the latest figures.
The Legal Ground Just Shifted: SB 1622 and the End of the 2018 Beach-Access Law
Erosion and legal beach access are different questions, but they collide in Walton County more than almost anywhere else in Florida. A 2018 state law had made it harder for local governments to recognize "customary use" — the public's long-standing practice of walking, fishing, and gathering on privately owned dry-sand beach — without a costly, parcel-by-parcel judicial process; it was widely understood at the time as protecting beachfront owners, including former Gov. Mike Huckabee, from public-access claims on their Walton County property. That law was repealed via Senate Bill 1622, signed by Gov. DeSantis on June 24, 2025, in Santa Rosa Beach. The repeal restores local authority for counties and cities to adopt customary-use ordinances covering recreational activities on privately owned beach without requiring that parcel-by-parcel litigation. It passed the Florida House 108-8 and the Senate 35-2; only two senators, Kathleen Passidomo and Don Gaetz, voted against it.
Gaetz's dissent is the detail worth sitting with if you're evaluating Seaside beachfront specifically: news coverage of the signing reported that Sen. Gaetz owns a home in Seaside itself, located across the street from the beach. That's the more precise, source-reported description; treat it as reported by that one outlet rather than independently confirmed against the county property appraiser's roll, and note it describes a near-beach home, not necessarily a directly Gulf-front parcel. Either way, the practical takeaway for a Seaside buyer is the same: the legal default around who can walk a privately owned stretch of dry sand in front of a Seaside home changed materially in 2025, after years of the opposite rule, and that history is worth understanding before assuming a beachfront or near-beachfront purchase carries the same access expectations it would have carried in 2019.
What This Means If You're Buying Beachfront (or Near It) in Seaside
Put together, the honest picture is neither alarming nor reassuring on its own. Seaside isn't named on FDEP's critically eroded list, but it sits in a narrow gap between two segments that are, inside a county whose total eroded mileage has grown over the past decade rather than shrunk. It's formally part of the same Corps-led renourishment project covering Rosemary Beach and the rest of the 30A corridor, backed by both federal cost-share dollars and a dedicated slice of the county's own Tourist Development Tax, but that project's design work still runs into 2027 and 2028 rather than delivering sand on a near-term timeline. And the legal rules governing who can use the dry sand in front of a Seaside home changed in a real, dated, verifiable way in June 2025, after seven years of a more restrictive regime.
Storm history adds a caution rather than an answer: a contemporaneous PR release described Seaside as escaping serious damage from Hurricane Michael in 2018, and Seaside-specific impact data from Hurricane Sally in 2020 wasn't confirmed in the sources checked for this page. Neither claim should be treated as a guarantee about the next storm. Before making an offer on Seaside beachfront or near-beachfront property, ask Walton County's coastal resource office and FDEP directly whether the specific address sits inside a currently mapped critical erosion area, what the Coastal Construction Control Line and its 30-year erosion projection mean for that exact parcel, and where the Study Reach 5 project timeline actually stands today. These are public records worth getting in writing before closing, not assumptions to carry to the table.

The "~73%/19 of 26 miles" critically eroded figure attributed to FDEP Secretary Alexis Lambert at the SB 1622 signing is treated as directionally consistent with, but not a direct substitute for, FDEP's own published 18.8-mile figure; this page's source PDF for FDEP's report could not be independently re-pulled in this research pass. Sen. Don Gaetz's Seaside property is described here as reported by Florida Phoenix (a home across the street from the beach) rather than independently confirmed against the property appraiser's roll. Hurricane Michael's 2018 impact on Seaside relies on a single contemporaneous PR release, not FDEP's own post-storm report; Hurricane Sally's Seaside-specific impact could not be confirmed at all. Critically eroded designations, renourishment timelines, TDT allocations, and beach-access law can all change after storms, funding votes, and future legislative sessions — confirm current status with FDEP and Walton County before making a purchase decision.
