Insurance in Baytown, Texas

Two counties, with Cedar Bayou between them

Baytown lies in both Harris and Chambers counties (the city's 2025 bond election notice lists precincts in each), and Cedar Bayou generally marks the line between them. The city's floodplain page links both counties' appraisal districts, which show the county for a parcel. If your address is on the Chambers County side and you carry a TWIA windstorm policy, TDI notes that you have one year from the date of damage to file a claim.

See the Harris County and Chambers County guides, and Houston for the rest of the metro.

Sinking land, storm surge and Goose Creek

The U.S. Geological Survey reports as much as 9 feet of subsidence in the Baytown area between 1906 and 1995, largely halted since the late 1970s here and across the Ship Channel in the Pasadena area. A National Research Council review of Hurricane Alicia found that the Brownwood subdivision, on a peninsula in Galveston Bay, had sunk more than 9 feet since 1940, and that some residents had filed three or four flood insurance claims in 10 to 15 years.

On August 18, 1983, a Baytown-area tide gage peaked at 10.4 feet above mean sea level. Surge of about 10 feet destroyed most Brownwood homes, FEMA offered to buy out the insured properties, and the land is now the Baytown Nature Center. Most home policies exclude flood, which makes surge a flood policy loss.

Goose Creek drains 27 square miles, its southern half in Baytown, to Tabbs Bay. In Hurricane Harvey in 2017, record flooding hit the creek north of Highway 146; south of 146, the district's plan says water ran higher in Hurricane Ike (2008) and Tropical Storm Allison (2001). Of 490 FEMA flood claims in the watershed since 1979, 432 came from north of I-10. FloodSmart says new flood coverage starts 30 days after purchase.

SH 146, I-10 and the paperwork after a crash

TxDOT's SH 146 study, from Langston Road north of I-10 to north of Ferry Road, cites fatal and incapacitating crashes, peak-hour congestion and heavy vehicle traffic. Dual left-turn lanes at I-10 and SH 146 are due in fall 2027. For the steps after a crash on either road, see car accident claims.

• Crash reports: police Records Division, 3200 N. Main Street, weekdays 8 a.m. to 5 p.m., or TxDOT online. Crashes without a CR-3 get a complaint-only report through Open Records.
• Baytown Alert: weather, police, fire, hazmat and utility notices. Outdoor sirens mean shelter in place for a chemical emergency.
• Floodplain Protection: flood zone determinations at 2123 Market Street and a link to the Harris County Flood Warning System for Goose Creek and Cedar Bayou levels.

Local risk: the federal disaster record in Baytown

Since 2000, FEMA has made 26 disaster, emergency or fire-management declarations covering Harris County. By type:

• Hurricanes and coastal storms: 12
• Floods: 4
• Severe storms (hail, wind, tornadoes): 4
• Wildfires: 2
• Winter and ice storms: 2

Most recent major disaster declarations:

• 2024: Hurricane Beryl
• 2024: Severe Storms, Straight-Line Winds, Tornadoes, And Flooding
• 2021: Severe Winter Storms
• 2019: Tropical Storm Imelda

Hurricanes and tropical storms are among the biggest home insurance risks in the Houston area, but how they reach a home depends on the address: storm surge is mainly a concern in low-lying areas near Galveston Bay, while most of Baytown faces wind, falling trees and flooding rain. Check whether your policy covers wind and hail, what that deductible is, and whether you need a separate flood policy.

Flood damage isn't covered by standard home, renters or business policies. Flood insurance through the NFIP usually has a 30-day waiting period, so it has to be in place well before a storm. For cars, flood damage falls under comprehensive coverage.

Declarations count how often federal help was declared, not how bad each event was. Statewide declarations (such as the February 2021 winter storm) are counted for every county, and the total includes the two 2020 COVID-19 declarations, which aren’t listed by type. These are Harris County figures; FEMA doesn't publish them by city.

Home insurance in Baytown

In Harris County, TWIA sells wind and hail coverage only for properties east of State Highway 146 and inside the city limits of La Porte, Morgan's Point, Pasadena, Seabrook or Shoreacres. If you're in that area and your home policy excludes wind and hail, TWIA may be an option once you've been turned down by a company writing that coverage and have a windstorm certificate (WPI-8). Elsewhere in Harris County, wind and hail are usually covered by your regular home policy. Baytown isn't one of those five cities, so its Harris County addresses are outside TWIA's area. The part of Baytown in Chambers County is different: all of Chambers County is in TWIA's coastal area.

Flooding isn’t covered by standard home or renters policies anywhere in Texas. With 16 flood or hurricane declarations in Harris County since 2000, it's worth pricing a flood policy even outside a mapped flood zone.

Texas law also sets claim deadlines: your insurer must acknowledge a claim within 15 days and accept or deny it within 15 business days of getting what it needs. See Texas home insurance.

Car insurance in Baytown

Every Texas driver needs at least 30/60/25 liability coverage. PIP is included and uninsured motorist coverage must be offered unless you reject them in writing. Given the storm and flood history here, comprehensive coverage, which pays for hail and flood damage to your own car, matters more than the minimum suggests. Rates vary by ZIP code within Baytown. See Texas car insurance.
