Three I-35E interchanges under construction at once

In Lewisville, TxDOT began reconstructing the I-35E grade separation and frontage roads at FM 1171 and Main Street in May 2023, with completion listed for May 2027, and started on the Corporate Drive and SH 121 Business interchanges in July 2025, with work scheduled into October 2029. Weather adds to it: on May 28, 2024, storm winds overturned an 18-wheeler near Highway 121 and Josey Lane while multiple wrecks were reported on I-35 in both directions.

Years of shifted lanes are a reason to know your collision deductible and whether rental reimbursement is on the policy. Lewisville's online police reporting does not take vehicle accident or hit-and-run reports, so call the department (non-emergency 972-219-3640). Under the Texas Department of Insurance's consumer guide, an unreported hit-and-run is not paid by uninsured motorist coverage. Crash reports are then requested from the Police Records Division in person or by mail.

Creek flooding and the 50 percent rule

On May 24, 2015, high water and stalled cars closed Corporate, Old Orchard and South Valley roads. New construction in Lewisville's floodplain must put its lowest floor two feet above the 100-year flood level, so older homes near the creeks may sit lower than newer ones.

One federal rule shapes a rebuild here: FEMA treats a building in a mapped flood zone as substantially damaged when repairs reach 50% or more of its pre-damage market value, whatever the cause, fire and tornado included, and it must then be brought up to the city's floodplain rules, which can mean elevating it. An NFIP policy's Increased Cost of Compliance coverage may help pay to elevate after a substantial-damage finding, and a homeowners policy may carry an endorsement for extra costs to meet building codes; both are worth checking. NFIP building and contents coverage are bought separately, so belongings need contents coverage, and a new NFIP flood policy usually starts 30 days after it is bought.

The Corps of Engineers said in July 2026 that its spillway modification at Lewisville Dam, completed in 1955 and one of the largest earthen dams in the nation, was nearing completion, with more than 70 anchors set through the spillway into bedrock; the wider dam safety project is scheduled to finish in 2027. The Corps says the dam was stable before work began and stayed fully operational. Wind and hail have their own record: an EF1 tornado on March 29, 2017 ran from Fox Avenue and Boxwood toward I-35E, and five homes lost part of their roofs; tennis-ball hail fell on June 11, 2023. Roof damage like that typically triggers the wind and hail deductible.

Who else depends on the same dam and highway

Lewisville is a Denton County city. Carrollton, on the Elm Fork below the lake, credits Lake Lewisville with buffering its floods, and Denton faces its own I-35 widening, scheduled into August 2029. Pages worth saving:

Local risk: the federal disaster record in Lewisville

Since 2000, FEMA has made 16 disaster, emergency or fire-management declarations covering Denton County. By type:

  • Hurricanes and coastal storms: 5
  • Severe storms (hail, wind, tornadoes): 3
  • Wildfires: 3
  • Winter and ice storms: 2
  • Floods: 1

Most recent major disaster declarations:

  • 2024: Severe Storms, Straight-Line Winds, Tornadoes, And Flooding
  • 2021: Severe Winter Storms
  • 2015: Severe Storms, Tornadoes, Straight-Line Winds And Flooding
  • 2007: Severe Storms, Tornadoes, And Flooding

Severe storms bring hail and wind. Check your home policy's wind and hail deductible (often a percentage of the dwelling limit) and your roof's age, and carry comprehensive coverage on your car.

Wildfire risk makes replacement-cost coverage, adequate dwelling limits and additional living expenses coverage especially important. Keep a home inventory somewhere other than your home.

Not every hurricane declaration here means a storm hit: many were emergency declarations for sheltering evacuees from the coast, or statewide declarations. Lewisville is far from storm surge, but tropical systems moving inland can still bring heavy rain and strong wind. Check your wind and hail deductible and whether you need a separate flood policy, since home policies leave flooding out.

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 Denton County figures; FEMA doesn't publish them by city.

Home insurance in Lewisville

Denton County isn't in TWIA's coastal area, so wind and hail are usually covered by your regular home policy, often with a separate wind and hail deductible. If you can't find coverage at all, the Texas FAIR Plan is the last-resort option.

Flooding isn’t covered by standard home or renters policies anywhere in Texas. With 6 flood or hurricane declarations in Denton 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 Lewisville

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 Lewisville. See Texas car insurance.
