You live in Friendswood, so you already know what a hard rain does to Clear Creek. Maybe you bought after Harvey and the seller told you the house "didn't flood." Maybe you've been here for decades and never carried flood coverage because your lender never asked. Either way, you're wondering whether you actually need a flood policy, what it would cover, and which map even applies to your street. Here's how it works in our own town.
Where does flood risk in Friendswood actually come from?
The short answer: Mostly from heavy rain overwhelming Clear Creek and three other local creeks on very flat ground, with storm surge from Galveston Bay as a second threat during tropical storms and hurricanes.
The City of Friendswood puts it plainly on its Flood Risk in Friendswood page. We're an inland city. Even so, we're "still affected by storm surge from Galveston Bay and riverine flooding from our four major creeks and their tributaries."
Those four creeks are Clear Creek, Chigger Creek, Cowards Creek and Mary's Creek. Clear Creek is the one everybody knows. According to the City's own history page, it's the line that divides the Galveston County part of town from the Harris County part.
The City also says heavy rainstorms cause most of the flood damage here. Our flat topography makes it worse. Water takes longer to drain through creeks and channels and leave town, so it has time to back up into streets and yards.
Clear Creek doesn't stop at the city limits, either. The Harris County Flood Control District describes the Clear Creek watershed as covering parts of Harris, Galveston, Brazoria and Fort Bend Counties and 16 cities, Friendswood among them. Rain that falls upstream in Pearland still has to get past us on its way to Clear Lake.
What Harvey showed us
The City lists Hurricane Harvey, in August 2017, as one of Friendswood's biggest flooding events. A 2019 flood study the City commissioned from Rice University researchers found Harvey caused flood impacts to over 2,000 single-family homes in Friendswood.
That same HCFCD report said Harvey's heaviest rain fell along I-45 "from near the City of South Houston and Pasadena southward to Friendswood and Webster." It also compared Harvey's peak one-hour rainfall on Clear Creek with Tropical Storm Allison's in 2001, and Harvey's was higher.
HCFCD's Clear Creek page lists other major events in the watershed too, including Allison in 2001, Hurricane Ike in 2008 and the spring floods of 2016. The City itself says it's concerned about repetitive flooding, and it runs a program to help residents protect their property.
Which flood map applies to your side of Friendswood?
The short answer: It depends on your county: the draft Harris County maps affect Harris County homes, while Galveston County homes stay on FEMA's Galveston County flood maps, so look up your own address before you assume anything.
The City's tax page puts it simply: "Friendswood is part of two counties, Galveston and Harris." Your appraisal district depends on which side you're on, and so does the FEMA map panel that sets your flood zone.
If you're on the Harris County side
In early February 2026, FEMA released draft floodplain maps for Harris County to local floodplain administrators through the MAAPnext project. In a February 11, 2026 statement, the Harris County Flood Control District said the drafts are "not final, not regulatory." It also said they reflect a 30% increase in rainfall rates, updated ground elevations and newer modeling.
Nothing about your flood insurance requirement changes yet. Community Impact reported HCFCD's projected timeline in February 2026: community engagement through January 2027, a formal appeal and comment period from February to May 2027, revisions through May 2028, and final approval projected for November 2028. The new maps take effect some time after that final approval.
You can look up your address on the MAAPnext interactive map at maapnext.org. If your home moves into a high-risk zone when the new maps take effect, and you have a federally backed mortgage, your lender will require flood insurance at that point.
If you're on the Galveston County side
The Harris County draft maps aren't the map for your address. Your flood zone comes from FEMA's Galveston County flood maps. Check it on the City's Floodplain Finder or at FEMA's Flood Map Service Center.
One more difference between the two sides has nothing to do with flood, but people mix them up. Galveston County is one of the 14 coastal counties the Texas Windstorm Insurance Association serves, so the Galveston County side of Friendswood is in TWIA's territory. TWIA covers wind and hail only, never flood.
Whichever side you're on, remember that a flood zone describes a mapped level of risk. It's the line where lenders start requiring coverage. It isn't a line water respects. We walk through the statewide version of that question in do you need flood insurance outside a flood zone in Texas.
Does Friendswood's CRS participation lower your flood premium?
The short answer: Yes, if you carry an NFIP policy — Friendswood participates in FEMA's Community Rating System, and the CRS discount applies to NFIP policies across a participating community, including homes outside the high-risk zone.
The Community Rating System is a voluntary FEMA program. It rewards cities that go beyond the NFIP's minimum floodplain rules, through things like stricter building standards, public outreach and drainage work. The City's Flood Insurance page says Friendswood is "an active participant" and that residents get premium discounts on eligible policies.
Here's how the classes work, according to the City's CRS program page. Discounts come in 5% steps. A Class 9 community gets 5%, a Class 1 gets 45%, and a Class 10 isn't participating, so it gets nothing.
Under FEMA's current pricing method, the CRS discount isn't only for homes in the high-risk zone. FEMA's 2023 CRS discount guide for agents says the discount "is applied to the full-risk premium for all NFIP policies in the Regular Program in a participating community, including policies outside of the Special Flood Hazard Area."
Doesn't my homeowners policy cover flood water?
The short answer: No — standard Texas homeowners policies exclude flood, so flood coverage comes only from a separate policy through the NFIP or a private flood insurer.
The Texas Department of Insurance says it in one line on its home insurance tips page: "Home insurance policies don't cover flood damage." That holds whichever carrier writes your homeowners policy and however much dwelling coverage you carry.
This surprises people most after a big storm. Wind can tear off shingles, and rain can come in through the damaged roof. That part may be a wind claim. Rising water that comes in at the floor is flood, and your homeowners policy won't pay for it.
Your cars are a separate question. A flooded car is usually an auto claim under comprehensive coverage, if you carry it. Our complete Texas auto insurance guide explains comprehensive. It's worth checking your declarations page before storm season.
If your homeowners policy is also up for review, maybe because of a non-renewal notice or a steep increase, start with our complete Texas home insurance guide for 2026. If your carrier has already said it won't renew, read what to do after a Texas home insurance non-renewal.
What does an NFIP flood policy actually cover?
The short answer: Up to $250,000 for the structure and up to $100,000 for your belongings, bought separately, plus up to $30,000 in Increased Cost of Compliance coverage for required rebuilding upgrades, though the building claim and that payment together can't exceed the $250,000 limit.
The City of Friendswood participates in the National Flood Insurance Program, which FEMA backs. The City says NFIP coverage "is available to all renters and property owners." So nobody in town is shut out of coverage because their home flooded before.
| Coverage | NFIP residential limit | Worth knowing |
|---|---|---|
| Building (structure) | Up to $250,000 | The structure itself and its built-in systems. It's bought separately from contents, with its own deductible. |
| Contents (belongings) | Up to $100,000 | Furniture, clothing, electronics. The NFIP pays actual cash value on contents, not replacement cost. |
| Increased Cost of Compliance | Up to $30,000 | Helps pay to meet floodplain rules, such as elevating, if the City finds your home substantially or repeatedly damaged. Eligibility rules apply. |
| Basements and outdoor property | Limited or excluded | Decks, fences, pools and most belongings in basements aren't covered. |
| Temporary housing | Not covered | The NFIP doesn't pay living expenses while you're out of the house. |
| Vehicles | Not covered | That's an auto comprehensive claim, if you carry comprehensive. |
Sources for the table are FloodSmart's buying a flood policy page and FEMA's agent guidance on coverage and Increased Cost of Compliance.
Renters and condo owners
The City specifically encourages renters to buy contents coverage. FloodSmart says a renter's NFIP policy covers your belongings up to $100,000. A landlord's policy doesn't cover your couch, and your renters policy almost certainly excludes flood.
If you own a condo or townhome in an association, the association's master policy usually handles the building. Ask the association what its flood policy covers and what it leaves to you. Then we'll match your contents coverage, and any unit coverage you need, to the gaps.
When does a new flood policy actually start?
The short answer: Usually 30 days after you buy it, though it can start sooner when the purchase is tied to a mortgage transaction, and the wait is one day if your home was recently mapped into a high-risk zone.
The City's flood insurance page says it directly: "Remember there is a 30-day waiting period before the policy becomes effective." A storm in the Gulf is not the time to shop. By then, a new NFIP policy won't start in time for that storm.
FloodSmart lists the exceptions:
- Mortgage transactions. No waiting period if you buy the policy when you make, increase, extend or renew a mortgage loan.
- Newly mapped into a high-risk zone. A one-day wait if your building is newly mapped into a high-risk zone and you buy within 13 months after the map revision takes effect.
- Changes at renewal. No wait when you change coverage as part of renewing an existing policy.
For Harris County homeowners, the map-change exception is worth knowing about now. When those maps take effect, some homes will be newly mapped high-risk. Still, being covered ahead of time is better than counting on an exception.
Is private flood insurance an option in Friendswood?
The short answer: Often, yes — private flood policies come from insurers outside the NFIP, and we quote them next to NFIP coverage so you can compare limits, deductibles, waiting periods and price.
The NFIP's $250,000 building limit covers the full rebuild for a lot of Friendswood homes, but not for every one. If yours would cost more to rebuild, a private policy, or private excess coverage on top of the NFIP, may be the way to insure the full value.
Private policies vary a lot. Some offer higher limits, replacement cost on belongings, or living expenses while you're displaced. Others are narrower than the NFIP in ways that only show up in the fine print. Waiting periods differ too. We read those terms with you instead of just handing you a number.
The one thing we won't do is steer you to a cheaper policy that leaves your home underinsured. If the right answer is to stay with the NFIP, we'll tell you so.
What should a Friendswood homeowner do before the next storm?
The short answer: Find your county and flood zone, check your current coverage, buy or adjust a flood policy on a quiet day, and get a side-by-side NFIP and private quote from people who know the neighborhood.
- Confirm your county and zone
Use the City's Floodplain Finder or FEMA's Map Service Center. If you're on the Harris County side, check the MAAPnext draft map too, so a future change doesn't catch you off guard.
- Read what you already have
Pull your homeowners or renters declarations page and any flood policy. Note your building limit, your contents limit and your renewal date. If you don't see a flood policy, you don't have flood coverage.
- Price the rebuild honestly
Compare your dwelling limit with what it would cost to rebuild today. If it's above $250,000, ask about private or excess flood.
- Don't forget contents
Building coverage doesn't pay for your belongings. Contents is a separate line on a flood policy, and it's the only line renters need.
- Buy on a sunny day
Count on the 30-day wait. Hurricane season starts June 1, so spring is the natural time to put a policy in place.
- Look at the City's help, too
The City publishes a guide to financial assistance for property protection measures on its Flood Risk page, and it runs its floodplain programs through the Floodplain Information pages.
The bottom line
Friendswood floods. The City says so, HCFCD's records say so, and anyone who was here in August 2017 remembers. Your homeowners policy won't pay for rising water, so a separate flood policy is the only way to cover it.
Which map governs your home depends on which side of Clear Creek you're on. The Harris County draft maps could change requirements there in a few years. Neither county line changes how the water moves.
