Selling a Friendswood TX Home with Imelda Flood History: Your Disclosure Game Plan

Does Imelda Flood History Have to Go on Your Seller Disclosure Form?

Yes, and skipping it is one of the more expensive legal mistakes a Texas seller can make. Tropical Storm Imelda hit southeast Texas in September 2019, dropping up to 43 inches of rain across Harris and Galveston Counties and causing an estimated $5 billion in damage statewide. Thousands of Friendswood homes took water, including neighborhoods along Mary's Creek drainage, sections of Annalea, and parts of Whispering Pines. If your home flooded during Imelda, Texas law and the TREC Seller's Disclosure Notice (form OP-H, also distributed as TAR-1406 by the Texas Association of Realtors) require you to disclose that history to every buyer before they enter a purchase contract. Hiding it exposes you to buyer lawsuits, rescission of the contract, and in some cases TREC license complaints against your agent.

What Imelda Actually Did to Friendswood

Imelda made landfall near Freeport on September 17, 2019, as a tropical storm, then stalled and produced catastrophic slow-moving rainfall through September 19. The storm ranked as the seventh-wettest tropical cyclone in U.S. history and fourth-wettest in Texas, according to the National Oceanic and Atmospheric Administration's storm events database.

Harris County, which includes the northern portions of Friendswood, received federal disaster designation DR-4466. The Texas General Land Office documented Imelda as covering six Texas counties: Chambers, Harris, Jefferson, Liberty, Montgomery, and Orange. Over 10,000 homes statewide were significantly impacted by flooding from that storm.

For Friendswood specifically, the impact was concentrated around drainage corridors:

• Mary's Creek runs through central and northern Friendswood and is the primary drainage artery for many neighborhoods in the 77546 ZIP code. Homes within a few blocks of Mary's Creek saw significant inundation during Imelda.
• Annalea subdivision (west side of FM-518 corridor) experienced flooding in lower-elevation sections due to sheet flow and creek backup.
• Whispering Pines and adjacent subdivisions on the Harris County side of Friendswood also reported flooding, though Friendswood straddles both Harris and Galveston Counties, and flood patterns varied by specific parcel elevation.
• Properties near Cowards Creek, a tributary that feeds Mary's Creek, also saw elevated flood risk during the event.

If you are unsure whether your property technically flooded during Imelda, check with your homeowner's insurance company, pull the original claim file if one exists, and look up your address in the Harris County Flood Control District's interactive mapping tools and the Harris County Flood Education Mapping Tool (FEMT).

TREC TAR-1406: Exactly What You Must Disclose

The Texas Real Estate Commission Seller's Disclosure Notice (TREC OP-H) is required for previously occupied single-family residences. Texas Realtors distribute the same form as TAR-1406. The form asks specific questions that directly cover Imelda-type flood history:

Key flood-related questions on the form:

1. Has the property flooded? Answer "Yes" if the home took water during Imelda, Harvey, or any other event. "Unknown" is not a valid response when you have actual knowledge.
2. Has the property been in a FEMA-designated flood zone? Disclose Zone AE status even if FEMA maps were later revised.
3. Has water ever penetrated a basement or crawl space? This applies if water entered interior spaces, including on slab construction.
4. Has there been any water damage, moisture, or mold? Remediation history and post-flood mold testing connect here.
5. Have any insurance claims been filed? Flood insurance claims attach to the property's NFIP loss history and are visible to buyers' lenders.

The Texas standard is disclosure to the best of your knowledge. But if you filed an insurance claim, received a FEMA Individual Assistance payment, or had a public adjuster assess the property after Imelda, you had actual knowledge. "I didn't know" is difficult to defend in that situation.

TREC revised the form in 2022 following the 87th Texas Legislative Session, which required landlords to disclose floodplain status and recent flooding history. The seller disclosure standard already covered this, but the legislative push reinforced it.

Harris County vs Galveston County: Does It Matter Which Side of the Line You're On?

Friendswood is unusual because it sits in both Harris County and Galveston County. The TREC disclosure form is the same regardless of county. However, the underlying flood mapping and local drainage authority differ:

Harris County portion of Friendswood: - Regulated by the Harris County Flood Control District (HCFCD), which has one of the most advanced flood mapping programs in the country following Hurricane Harvey. - The Harris County Flood Education Mapping Tool (harriscountyfemt.org) provides a parcel-level view of which properties flooded during specific events including Harvey 2017 and Imelda 2019. - Harris County's MAAPNext program has been updating floodplain maps to reflect more recent hydrology. If your property was remapped into or out of Zone AE, document that carefully.

Galveston County portion of Friendswood: - Galveston County floodplain administration operates separately from Harris County. The Galveston County Appraisal District at galvestoncad.org handles parcel data. - FEMA maps for the Galveston County side use the same Zone AE and Zone X designations but were updated on different amendment cycles. - Galveston County has its own floodplain administrator. Contact Friendswood's floodplain administration through the City of Friendswood to verify current zone status for your specific parcel.

For disclosure purposes, both counties require you to disclose actual flooding events regardless of which flood zone designation your parcel carries. A property in Zone X that flooded during Imelda still requires full disclosure.

FEMA Letters of Map Amendment and Revision: How to Use Them

If your property sits in a FEMA Special Flood Hazard Area (Zone AE) but your elevation is actually above the base flood elevation, you may qualify for a Letter of Map Amendment (LOMA) or Letter of Map Revision Based on Fill (LOMR-F). Here is why that matters for your sale:

• A LOMA officially removes your property from the mandatory flood insurance purchase requirement.
• Buyers using conventional financing will not be required to carry flood insurance if the property has a valid LOMA on file.
• A LOMA does not erase flood history. You still disclose the Imelda flooding event on the TAR-1406 form, but you can present the LOMA documentation as evidence the property's current regulatory status has improved.

Request LOMA status from FEMA at the FEMA Flood Map Service Center. If a LOMA was previously granted, it will be on file there. If you believe you qualify but lack one, a licensed engineer or surveyor can prepare the elevation certificate and application for roughly $500 to $1,500. Start the process at least 90 days before listing; FEMA processing times vary, and a LOMA in hand removes one of the most common buyer objections.

How Flood History Affects Your List Price and Days on Market

Let's be honest about what buyers think when they see a flooded property on the disclosure form. Some walk. Others negotiate hard. The buyers who stay are often investors or experienced homeowners who understand flood risk and price accordingly.

Factors that influence how much a flood history discounts your value:

• Depth of flooding. Two inches in the garage is different from three feet in the living areas. Document the actual depth with photos, adjuster reports, or FEMA claim files.
• Quality of remediation. A licensed remediation contractor, mold clearance testing, and documented repair completion reduces buyer concern. A clean post-remediation mold report belongs in your disclosure package.
• Whether it happened again. A home that flooded in Harvey (2017) and Imelda (2019) signals a pattern. Buyers and lenders will see both claims in the NFIP loss history.
• Current flood zone status. If the property is still in Zone AE and the buyer is financing, mandatory flood insurance becomes part of their carrying cost calculation. Price accordingly.
• Elevation certificate. A current elevation certificate from a licensed surveyor is one of the most valuable listing documents you can provide. It shows buyers precisely where your finished floor elevation sits relative to the base flood elevation.

In the current Friendswood market, well-remediated homes with full flood documentation and an elevation certificate generally sell at a 5 to 12 percent discount compared to comparable non-flooded properties, depending on flood zone and history. Omitting that history tends to produce worse outcomes: deals that collapse during option, re-negotiations at appraisal, or post-closing litigation.

Frequently Asked Questions

What if I bought the house after Imelda and I was never told it flooded?

Your disclosure obligation is limited to what you actually know or should have known. However, if there is a prior NFIP insurance claim on the property, that loss history is attached to the address and will appear in a flood determination report ordered by the buyer's lender. If you later discover the prior owner failed to disclose a flood event to you, you may have a claim against that seller, but you still need to disclose what you know on your own disclosure form.

Is there a difference between the TREC form and the TAR-1406?

The TREC Seller's Disclosure Notice (OP-H) is the statutory form required by the Texas Property Code. The TAR-1406 is the Texas Association of Realtors version of the same form with some additional questions. Most licensed Realtors in Texas use the TAR-1406 because it is more comprehensive. Either form satisfies the legal requirement, but the TAR-1406 gives you more space to explain circumstances and provide context.

Can I sell my Friendswood home as-is with undisclosed flood history?

No. Selling "as-is" in Texas does not waive the seller's statutory disclosure obligation. An as-is clause means the buyer accepts the property's physical condition and cannot demand repairs. It does not release the seller from the duty to disclose known material defects, including flood history. Relying on an as-is clause to cover undisclosed flooding is a misunderstanding that generates lawsuits.

How does the Mary's Creek floodplain affect buyer financing?

If your property sits in a FEMA Zone AE area mapped as the Mary's Creek 100-year floodplain, any buyer using federally backed financing (FHA, VA, conventional with Fannie/Freddie) is required to carry flood insurance. Lenders will order a flood determination certificate at closing. Annual flood insurance premiums under the National Flood Insurance Program can run $1,200 to $4,000+ depending on elevation and coverage amounts, which directly affects the buyer's debt-to-income ratio and purchasing power. Factor this into your pricing strategy.

What if my home is in Galveston County rather than Harris County Friendswood?

The disclosure obligations are identical regardless of county. The difference is in which floodplain maps and resources apply. Galveston County uses FEMA FIRM panels that are separate from the Harris County panels. Verify your exact parcel's county through the Galveston County Appraisal District at galvestoncad.org or the Harris Central Appraisal District at hcad.org, depending on which county your parcel falls in. The FEMA Flood Map Service Center will pull the correct panel for any address.
