Two days of heavy rain left standing water on streets and in swales across Port St. Lucie, St. Lucie West, Tradition and Fort Pierce. I hope you and your home stayed dry. Once the water goes down, here is what this kind of storm means if you own a home here, or are thinking about buying or selling one.
- The National Weather Service issued flood advisories for St. Lucie County on Sunday and again Monday morning, with several inches of rain falling in a short time.
- Most street flooding here comes from rain falling faster than swales, canals and ponds can drain it, not from rivers or the ocean. That is why homes outside a high-risk flood zone can still see water.
- Standard homeowners policies generally do not cover flood. Flood policies through the National Flood Insurance Program usually take 30 days to start.
- Florida sellers must disclose known flood damage, flood insurance claims and flood assistance at or before signing a contract.
- For buyers, a rainy week is a useful time to look at a home. Pay attention to the swale, the driveway culvert and where water collects.
What happened this weekend
On Sunday, November 1, the National Weather Service put St. Lucie County under a flood advisory, along with parts of Martin, Indian River and Okeechobee counties. Radar estimates showed 2 to 5 inches of rain across much of that area. Another advisory went out Monday morning for central St. Lucie County, covering Port St. Lucie, St. Lucie West and Tradition, after 2 to 3 more inches fell.
An advisory means minor flooding in low-lying spots and places with poor drainage. It is a step below a flash flood warning. For most of us that meant flooded intersections, full swales and a slow drive to work. If you are still seeing water, please don’t drive through it. Depth is hard to judge, and a few inches of moving water is enough to stall a car.
Why Port St. Lucie streets flood after heavy rain
Port St. Lucie drains mostly through a network of roadside swales, driveway culverts, canals and retention ponds. The city says it has roughly 1,200 miles of swales. When several inches fall in a few hours and the canals and ponds are already high, water backs up into streets and yards until the system catches up. City officials have described this as the system working as designed, just more slowly than residents would like.
A few things owners often don’t know:
- The swale in front of your home is partly your job. Under city code, property owners maintain the swale and driveway culvert between the edge of the pavement and their property line. Keeping it mowed and clearing out any blockage in the culvert helps your street drain faster.
- You already pay for stormwater work. The city’s annual stormwater assessment shows up on your property tax bill. Recent increases are going toward watershed projects, canal work and faster swale and culvert replacement.
- Report problems to the city. If a culvert is collapsed or water sits for days after the rain stops, contact the City of Port St. Lucie Public Works department. Fort Pierce and unincorporated St. Lucie County residents should contact their own city or county.
Flood zones: what they tell you, and what they don’t
Every property is on a FEMA flood map. You can look up any address for free on FEMA’s Flood Map Service Center or through the county. Here is a simple guide to the zones you will see most often on the Treasure Coast:
| Zone | What it generally means | Flood insurance with a federally backed mortgage |
|---|---|---|
| X (unshaded) | Minimal flood hazard on the map | Not required by the lender, but available |
| X (shaded) | Moderate flood hazard | Not required by the lender, but available |
| A / AE | High-risk area (Special Flood Hazard Area) | Required |
| V / VE | Coastal high-hazard area with wave action | Required |
Much of Port St. Lucie is mapped as zone X, and that is where people get caught off guard. Flood maps mostly measure risk from rivers, lakes and storm surge. They do not show which street collects water when a slow-moving storm sits over the city. Weekends like this one are a reminder that zone X means lower risk, not no risk.
If you own a home here
- Check what your policy covers. Homeowners insurance generally excludes flood damage from rising water. Flood coverage is a separate policy, either through the National Flood Insurance Program or a private flood policy. My Florida home insurance questions guide covers the basics.
- Don’t wait for the next storm. NFIP policies generally have a 30-day waiting period before coverage starts, with limited exceptions such as a policy bought at closing.
- Citizens policyholders, note the 2027 date. Citizens Property Insurance Corporation, the state-created insurer, has been phasing in a flood insurance requirement for homes with wind coverage. Starting January 1, 2027, it applies to all dwellings regardless of value. Condo unit-owner policies and policies without wind coverage are exempt. Confirm your own renewal details with your agent.
- Document any damage now. Take photos and keep receipts for any repairs. If you sell later, you will need that record.
If you are buying this season
A rainy week is one of the best times to see a home, because you see how the lot actually handles water. When I tour homes with buyers after a storm, here is what we look at:
- Is water standing in the swale or the street days after the rain stopped?
- Is the driveway culvert open on both ends, or crushed or full of sediment?
- Does the yard slope away from the house? Is there water staining near the foundation, on baseboards or at sliding doors?
- How high is the floor compared with the street? An elevation certificate, if the seller has one, shows this, and it can affect flood insurance pricing.
- What does the seller’s flood disclosure say? (More on that below.)
Get flood insurance quotes during your inspection period, even in zone X, so the cost is part of your decision and not a surprise at closing. If you are comparing areas, my Tradition and St. Lucie West guides are a good start, and first-time buyers can find the full process in my first-time homebuyer guide.
If you are selling: Florida’s flood disclosure rule
Florida law (section 689.302 of the Florida Statutes) requires sellers of residential property to give buyers a flood disclosure at or before the time the contract is signed. As updated effective October 1, 2025, the disclosure covers whether the seller:
- has filed a flood damage claim with an insurance provider, including the National Flood Insurance Program;
- has received assistance to repair flood damage; and
- knows of flooding that damaged the property during their ownership.
Similar disclosures now apply to residential leases of a year or longer. If water came into your home or garage this weekend, write down what happened and what you fixed. Disclosing it clearly, with repair records, almost always goes better than a buyer’s inspector finding it later. If your street simply had water in the swale and nothing reached the home, that is a different situation. Check with a real estate attorney if you are unsure what applies to you.
Before you list, clear the swale and culvert, fix gutters and downspouts, and regrade any low spots near the house. Those small fixes show up well when a buyer visits after a rain.

A note on staying safe
If more rain is in the forecast, sign up for St. Lucie County emergency alerts, keep storm drains and swales near you clear of debris, and avoid driving through standing water. Water over the road can hide washouts, open culverts and downed lines.
