Raise It, Keep It Low, or Start Over: Marine Way and the Historic-Home Flood Question in Delray Beach

In Delray Beach's historic districts, a buyer can learn a home's flood height from a title search. Delray amended its floodplain rules in 2024. Under those rules, a flood variance is granted only after the applicant signs a statement agreeing it "shall be recorded in the Office of the Clerk of the Court in such a manner that it appears in the chain of title of the affected parcel of land." That language comes from Ordinance 05-24, which passed on final reading November 4, 2024, and took effect immediately.

That matters because on Delray's historic streets, flood height comes out of a negotiation. Over the past 14 months, the city has answered the same question three different ways: what happens when the 9-foot finished-floor minimum meets a contributing historic house. Owners won those answers one address at a time at public hearings, and some of the results now travel with the property.

One Question, Three Answers Since August

The Marina Historic District sits south of Atlantic Avenue along the west side of the Intracoastal Waterway. Del-Ida Park lies north of downtown. Three recent decisions in these two districts show the outcomes available to an owner.

The houses on Marine Way are close neighbors, and their outcomes went in opposite directions. One house will sit several feet above the federal minimum. The other kept a floor about four feet below it. The Del-Ida Park lot took the third path.

Why Raising a Historic House Took Nearly a Year

The 46 Marine Way case shows that raising a house is a design review as much as an engineering decision. In August 2025, the plan was to raise the Mediterranean Revival home to 14 feet and add a three-story addition. According to The Coastal Star, the City Commission denied it 3–2 after a 6½-hour meeting on August 19. Commissioner Juli Casale said the project "risks the integrity of our historic district," the paper reported. City staff argued the changes would create a "false sense of historical development." The owner told the commission, "I could have demoed the property, but that wasn't my choice."

A revised plan came back in 2026. Citizen Portal reported that the Historic Preservation Board denied it on July 1, with board members saying the addition's mass and height still overwhelmed the contributing house. Less than seven weeks later, the City Commission approved the package. Citizen Portal's summary of the August 18 meeting records a 5–0 vote and notes that the owner removed the third story and reduced the massing before approval. The Legistar record for Resolution 127-26 lists what was approved:

• A certificate of appropriateness
• Demolition of the contributing accessory structure
• Vertical relocation of the main house
• Two setback variances
• Waivers to two visual compatibility standards

A raise approval in a historic district bundles setbacks, height compatibility and accessory buildings together with the floor height. Lifting the house changes how it sits on the lot, so the setbacks and visual standards have to be reworked along with it.

What the Historic Exception Actually Covers

Two separate provisions keep a historic floor low, and 110 Marine Way needed the second. The first is an exclusion. Under the National Flood Insurance Program, "substantial improvement" means work costing 50 percent or more of a building's value, and it usually triggers full flood-resistant construction. The federal definition in 44 CFR §59.1 excludes alterations to a historic structure as long as the work does not end its historic designation. Delray's Land Development Regulations use the same 50 percent threshold and the same carve-out.

The federal definition of a historic structure includes buildings listed individually on the National Register, contributing structures in a registered historic district, and places listed in qualifying state or local preservation inventories. FEMA's floodplain bulletin on historic structures says being located in a historic district does not qualify a building on its own. New construction and noncontributing buildings in the same district still follow the ordinary rules.

The exclusion only decides whether a project triggers the substantial-improvement rules. Keeping a floor below the required elevation is a separate step, and 110 Marine Way's notice described it as a variance from LDR §10.1.1(C)(2), sought along with additions and exterior changes to the contributing structure. Delray's variance provision for historic buildings, §10.1.7(E), applies only when the work does not prevent continued designation and the variance is the minimum needed to preserve historic character and design.

This explains the Del-Ida Park result. Once 14 George Bush Boulevard's contributing house comes down, the new homes on the split lot are new construction. The commission had already approved lot-size waivers under Resolution 126-26 on August 18, reducing the minimum from 9,500 to 9,000 square feet so the parcel could become two lots. Under the city's published guidance, demolition in a historic district needs board approval, and it cannot happen until a building permit has been issued for the approved replacement.

The Floor Height Shows Up in the Insurance File

A low floor saved by a variance has a cost, and the paperwork says so. Federal rules in 44 CFR §60.6(a)(5) require a written notice that a variance for construction below the base flood level "will result in increased premium rates for flood insurance." Delray's version, §10.1.7(H)(4), goes further. The notice has to state the difference between base flood elevation and the proposed lowest floor, and it has to say the cost of federal flood insurance will be commensurate with the added risk, "up to amounts as high as $25.00 for $100.00 of insurance coverage."

Under FEMA's Risk Rating 2.0, fully in place since April 1, 2023, premiums use property-specific factors that include building elevation, distance to water and replacement cost. FEMA's October 2025 manual treats qualifying historic buildings as Pre-FIRM construction. The Pre-FIRM discount itself is set by statute, and historic status does not guarantee a particular premium. The same manual lays out when a prior owner's Pre-FIRM discount can carry forward on an assigned policy, and new-owner status affects how the annual cap is calculated. An elevation certificate is no longer required to buy coverage. Submitting one can still show whether better elevation data changes the rate. Federal law caps annual increases in the chargeable risk-premium rate at 18 percent for most properties, with statutory exceptions. The cap does not apply to every part of the total bill.

When a buyer prices a historic house on Marine Way, the insurance quote and the variance record describe the same decision a prior owner made.

The Paper Trail Around a Historic Purchase

The documents fall into three groups:

1. The recorded record. Under §10.1.7(H)(3), a floodplain variance is recorded so it appears in the parcel's chain of title.
2. The seller's flood disclosure. Florida Statute §689.302 requires the seller of residential property to provide a flood disclosure at or before signing of the sales contract. The current form, as amended in 2025, asks whether the seller knows of flood damage during their ownership, filed a flood insurance claim including through the NFIP, or received flood-damage assistance including from FEMA.
3. The city's file. Exterior alterations to designated properties are reviewed for a certificate of appropriateness. Under the fee schedule adopted October 15, 2024, a certificate costs $500 for minor work and $1,000 for major work. Relocation costs $825, demolition of a principal structure $1,650, and a variance $1,575.

The fees are small next to the time involved. 46 Marine Way went through hearings in August 2025 and in June, July and August 2026 before it reached approval. The city's published process pages do not give a typical end-to-end turnaround time.

A Few Distinct Questions

Does Florida's 2025 SB 180 change how Delray counts the 50 percent? SB 180 created §163.31795, which bars NFIP-participating local governments from enforcing a cumulative substantial-improvement period. The Chapter 10 text reviewed for this post looks at the cost of the proposed work and does not set a multiyear cumulative period. Delray joined 24 other local governments in a September 2025 lawsuit challenging other parts of the law. As of WUSF's December 2025 report, a judge had denied a preliminary injunction and let the case continue. Two 2026 bills that would have amended SB 180 died in committee on March 13, 2026.

Does every older house in the Marina Historic District qualify for the exception? No. Location in the district doesn't qualify a building by itself. The federal definition covers contributing structures, individually listed buildings and qualifying state or local listings, and the exclusion holds only while the work keeps that designation in place.

Is an approval permanent? Citizen Portal's summary of the August 18 meeting lists the 46 Marine Way approval as effective August 17, 2026, with a sunset of August 17, 2027.
