Drainage & concrete leveling in Manor, TX

Manor has a claim no other town on this list can make. The USDA's official type location for the Houston Black soil series is in Travis County, measured from the corner of Farm Road 973 and U.S. Highway 290 in Manor. Houston Black is the textbook Vertisol, a clay that shrinks and swells sharply as moisture changes, and the building-site notes on the series call that movement a serious limitation. The Texas Water Development Board's state soil sheet makes the same point. If you own a home in Manor, you are living on the soil that defines the problem. Because the clay barely drains, rain that lands on a Manor lot often has only two ways to go: across the surface or slowly down into soil that swells and pushes back against your concrete. The Houston Black description also notes that the clay can form wide cracks when dry, which is why you may see a lawn split open in August and then turn slick after the first big storm.

Two creeks drain the area. Gilleland Creek, about 27 miles long, flows from northwest of Pflugerville to the Colorado River, and Wilbarger Creek, around 42 miles long, runs from north of Pflugerville to the Colorado River in Bastrop County. Travis County approved a parks bond in 2011 that supported buying land along these creeks for greenways in eastern Travis County, so some creek corridors now stay open. The ground around Manor is mostly flat to gently rolling prairie, so storm water spreads wide before it finds a channel. Lots near the creek corridors and their small tributaries can get fast runoff in a hard storm. Lots in the flats collect water that sheet flows from higher ground and then sits. We check slope and neighbors before we plan any outlet. We look at which way the water travels across your lot and the lots next to it, because a fix that only moves water to the neighbor is not a fix.

Manor was founded in 1872 on the Houston and Texas Central Railway, and for decades it stayed a small farm and rail town. The city reports about 125 people in the mid-1880s, a drop to around 1,200 by the 1930s, and today more than 21,000 within city limits with another 13,000 in the extraterritorial jurisdiction. US-290 east to Houston and SH 130, which opened its first segments in 2006, put Manor within easy reach of Austin and drove much of the growth. That means three types of homes. Older houses near the original townsite sit on larger lots with settled grading. Subdivisions from the early growth years have mature trees and aging concrete. Brand-new neighborhoods have small lots, builder grading and soil that is still settling. Ask your neighbors when their street was built, since homes from the same builder and year usually share the same grading quirks and the same weak spots in their drainage.

On Houston Black, even small mistakes show up fast. We see downspouts that empty right at a foundation, dark wet patches along fences, flower beds that hold water against brick and driveway panels that drop where the soil shrank or washed out. Sidewalks lift at joints. Garage aprons tilt toward the door. In new subdivisions, shallow swales can fill with sod or settle so that water sits behind the house for days. French drains, regrading, catch basins, underground downspout drains, dry wells and foam leveling all have a place. We do not do structural foundation repair, so stair-step cracks or doors that stick should be seen by a structural engineer, with drainage fixed alongside. A downspout that empties against the slab is the single most common cause, and it is often the cheapest thing to correct first.

Local rules matter. Many Manor neighborhoods have HOAs with approval processes, and some lots sit on recorded drainage easements where changes may need city review. We cannot state the City of Manor's grading and permit requirements, so contact the city and your HOA before you start. Texas Water Code Section 11.086 makes it unlawful to divert or impound natural surface water so that it damages a neighbor's property, so your drain outlet should go to the street, a proper swale or an approved point. If a dispute develops, see an attorney. Texas law also requires everyone, homeowners included, to contact Texas811 at least two business days before digging. With gas, water, electric and fiber lines being added as Manor grows, that call is worth making every time. Keep your approval letters and 811 ticket number together in one folder so you can show them if a neighbor or the city asks.
