St. Lucie County Says No to 500 Homes Over Drainage: What Buyers and Owners Should Check After the Flooding

On November 11, 2026, St. Lucie County commissioners voted 3-2 against a land-use change that could have allowed close to 500 homes on about 34 acres near South 25th Street and West Midway Road. County staff had recommended approving it with changes to protect wetlands. A majority of commissioners didn't think the drainage question had been answered. The site sits below the surrounding roads, and it already takes runoff from a much larger area around it. (Read the full story at Treasure Coast Today.)

The vote came days after heavy rain flooded roads and homes in parts of the county. The county has made an emergency declaration official, and residents asked commissioners for drainage studies and a plan to fix it. If you're buying, selling or already own a home here, this is a good time to look at how flooding affects your decisions.

Why this vote matters to home buyers

The Treasure Coast still needs more housing. But whether a big project gets approved depends more and more on where its water will go. When a low site gets built up with fill, the rain it used to hold has to go somewhere else. Usually that means canals, ditches and pipes that already serve the homes next door. Whatever happens next with this property, expect drainage to be a central question for new subdivisions across St. Lucie County.

For buyers, the takeaway is simple: a flood zone letter on a map does not tell you everything. Local drainage, street elevation and how a neighborhood handled the last big storm matter just as much.

Five things to check before you buy

1. Read the seller's flood disclosure. Florida law (Section 689.302, Florida Statutes) requires sellers of residential property to give buyers a written flood disclosure at or before the time the contract is signed. Since October 1, 2025, it also covers whether the seller knows of flooding that damaged the home while they owned it, any flood insurance claims, and any flood assistance they received from any source. Read it carefully and ask follow-up questions.
2. Look up the flood zone yourself. Enter the address at FEMA's Flood Map Service Center (msc.fema.gov) or the county and city GIS maps. Ask whether the seller has an elevation certificate. Remember that many homes that flood are outside the high-risk zones.
3. Get a flood insurance quote during your inspection period, not after. Standard homeowners policies do not cover flood. A quote early on tells you the true monthly cost before you are locked in.
4. Know the waiting period. A new National Flood Insurance Program policy usually takes 30 days to start. If you buy it as part of getting your mortgage, there is generally no waiting period. Private flood policies have their own rules.
5. Drive the street after a heavy rain. Look for standing water, high-water marks and sandbags. Talk with neighbors. Ask the HOA or the county whether any drainage work is planned for the area.

If you already own a home

• If you don't have flood insurance, get a quote now. Remember the 30-day wait for most new NFIP policies.
• Take dated photos of any water that reaches your yard, garage or home. They help with insurance claims, and as a seller you'll need to know your flood history for the disclosure.
• Keep culverts and swales on your lot clear, and report blocked drains to the county or your city.
• Follow the county's drainage meetings. Decisions made there can affect your home's value and your insurance costs.

Frequently asked questions

Does a home in Flood Zone X never flood?

No. Zone X means FEMA rates the risk as lower, not zero. Heavy rain and local drainage problems can flood homes in any zone. That is why the disclosure and your own checks matter.

Do I have to buy flood insurance?

If the home is in a high-risk flood zone and you have a federally backed mortgage, your lender will require it. Elsewhere it's optional, but it's often worth pricing, especially for low-lying properties.

Can a seller skip the flood disclosure if the home sells as-is?

The Florida flood disclosure applies to residential sales in general. Selling as-is limits what the seller will repair, not what they have to disclose. Ask a Florida real estate attorney about your specific situation.
