Concrete Contractor
in Missouri City, TX

Do I need a permit to replace my driveway or pour a slab in Missouri City?

Yes. The city says a new concrete slab and a driveway repair or replacement both still need a permit and inspections. Work at the street needs a Right-of-Way Use Permit, and contractors must be registered with the city before they start. We pull the permit at 1522 Texas Parkway and book the inspections through the MCTX Self Service portal.

I live in Sienna. Is my permit from the city or Fort Bend County?

It depends on your lot. The former Sienna MUD No. 2 was annexed on August 21, 2023, so those homes now get city permits. The parts still in the ETJ go to Fort Bend County Engineering in Richmond, which wants a Residential Development Permit for any structure of 400 square feet or more. We check which one applies before we price.

Why does my slab keep cracking?

Much of the older city sits on Lake Charles clay, rated very high for shrink-swell. It swells in the rain and shrinks in drought, and that movement cracks slabs. In Sienna the Brazos soils swing from loam that swells less to very expansive clay. The fix is a geotech report first, then a post-tension slab or piers designed to it.

My backyard stays wet for days after rain. Is my lot graded wrong?

Usually it is not sloped at all. The soils here are mapped at zero to one percent slope, so water sits. The city tells owners to grade soil away from the house and keep the swales between lots clear. Drainage upkeep is shared by the city, your MUD and the county drainage district.

Can I add fill or build in the floodplain near the Brazos?

Only with a floodplain Development Permit and a grading plan signed and sealed by a professional engineer. Putting fill in the Special Flood Hazard Area needs a local permit too. If the work costs more than half the market value of the building, the building must meet the floodplain rules. Usually that means raising it above the flood level.

Does Missouri City have zoning, unlike Houston?

Yes. There is a zoning ordinance, a Zoning Board of Adjustment and published Architectural Design Standards. Newly annexed land comes in as suburban district until council gives it permanent zoning. Check the zoning before you plan a shop building or a commercial use, because it can rule the use out.
