Foundation Repair in Missouri City, TX

Who handles drainage on your street?

In Missouri City, the answer to "who maintains the drainage?" isn't always the City. The City's watershed master plan page says Missouri City maintains drainage in some areas but not citywide; most local drainage systems are maintained by a Municipal Utility District (MUD) or a Levee Improvement District (LID). The City permits drainage facilities inside city limits, and Fort Bend County permits them in the extraterritorial jurisdiction. To find out who maintains yours, the City says to call 281-403-8500 (City of Missouri City, Watershed Master Plan Update, official city page, checked 2026-10-15). The same page says the last comprehensive update to the City's drainage master plan was in November 1987, with minor updates since. The page describes an update that was scheduled to be finished by fall 2021. Its scope included backwater from the Brazos River at points inside the city and what-if flooding from local rain and high Brazos levels. The page also links a Drainage Concern Map where residents could flag a problem spot; call the City to ask whether it's still in use (same source).

"Foundation repair of any kind" needs a permit

Missouri City's list of required residential permits includes "foundation repair of any kind," along with structural alterations, flatwork and roof work. It also says residential permits must be posted where they're visible from the street (City of Missouri City, Types of Construction Permits, checked 2026-10-15). The City's residential building permit application has a "Foundation Repair" work class, asks for the property's flood zone, and its fee schedule lists foundation repair at $52 (Missouri City residential building permit application, checked 2026-10-15). A City staff report on development activity from October 1, 2023 to September 30, 2024 lists foundation permits among its "Instant Permits," and shows 12 foundation repair contractor registrations issued in that period (Missouri City staff report, quarterly development activity, checked 2026-10-15). The City's code requires contractors working in Missouri City to register with the City before starting work (City of Missouri City, Contractor Registration, checked 2026-10-15). Ask your contractor to confirm their registration and who will pull the permit; the City posts a list of registered contractors on that page. Texas does not have a statewide license for foundation repair contractors; cities may require permits.

Lake Charles clay

The 1960 USDA soil survey of Fort Bend County says Lake Charles clay "has a great swelling and contracting ratio," and that when it dries, cracks form 2 to 6 inches wide, 1 to 6 feet long and as much as 3 feet or more deep (Soil Survey of Fort Bend County, USDA, 1960, checked 2026-10-13). Because it's a 1960 county-wide soil map, it won't tell you which clay sits under a particular Missouri City subdivision; the contractor who visits can look at your yard and slab.

Two counties' flood maps

The City's floodplain page lists FEMA flood maps for its Fort Bend County areas, effective April 2, 2014, and for its Harris County areas, with a Flood Insurance Study effective June 9, 2014. It also offers an interactive floodplain map and links drainage master plans for Lower Oyster Creek and Mustang Bayou (City of Missouri City, Floodplain Maps, checked 2026-10-15). The City's drainage page notes that owners in lower-risk areas can still see localized flooding (City of Missouri City, Drainage, checked 2026-10-15).

Price, insurance, and next steps

We haven't collected Missouri City quotes. For a sense of scale, our Houston cost page gathers published ranges and names where each one comes from. Insurance: your own policy determines whether foundation work is paid for, so your insurer or agent is the one to ask. For background on policies and claims, see the Texas Department of Insurance consumer guide (TDI home insurance guide, updated 6/1/2026, checked 2026-10-13). Quote requests are coming soon. For now, call (832) 646-1494 or email [email protected].
