Starting from a 1980s patio or from a bare slab and a fence?
The two kinds of Missouri City backyard call for different first steps. In Quail Valley and Lake Olympia, most homes date from the 1970s through the 1990s and already carry a patio slab, a pool deck, or both, and those surfaces have been riding Fort Bend clay for decades. Before we draw anything we check whether the old slab is thick enough to carry cover columns, whether it has settled away from the house, and whether it still drains toward the yard instead of the foundation. A slab that is sound gets kept and extended. A slab that has heaved or cracked through gets cut out where the new structure lands, so the columns bear on fresh footings and not on a guess.
In the Sienna-area sections still building out, the yard is often a builder patio the size of a doormat and a fence line, which is simpler in one way and harder in another. There is no old work to fight, but every drainage decision is new. We set patio elevations so water sheds away from the slab on all sides, tie new hardscape into the swales the builder graded between lots, and route downspouts from the cover to daylight rather than to the neighbor's fence. If a pool is in the plan or already there, the deck, the cover footings, and the equipment pad get laid out together so nobody has to saw-cut finished concrete later.
