Yard Grading & Regrading:
How It Works & What to Get Right

The first thing we do on a grading job is shoot elevations across the entire area with a laser level. That means setting the level, running a grade rod to multiple points in a grid, and recording exactly what the existing ground elevation is at each point relative to a reference datum — typically a fixed point at the house foundation or a known benchmark on the property.

This gives us a real picture of where water goes today: which direction slopes actually run, where the low points are, and what the relationship is between the yard and the house. On many properties, the visual appearance is misleading — areas that look like they slope away from the house actually drain back toward it, or there are subtle saddle points in the middle of the yard that create two low zones instead of one.

Without this data, you're guessing. We don't design a cut/fill plan until we have elevations from enough points to understand the full site.

Grading work moves a lot of material. Even if the intent is shallow surface work, equipment passes over the same ground multiple times, and the blade or bucket can easily reach 6 to 12 inches below grade. Texas law requires an 811 utility locate before any excavation, and grading qualifies.

The 811 service marks public utility lines — gas, electric, water, telecom — on the property. What it doesn't mark are private utilities: irrigation systems, septic systems, water well lines, and any other underground infrastructure the homeowner installed or inherited with the property. On larger rural and semi-rural lots in Katy, Fulshear, and Needville, these private lines are common and not always documented or remembered.

Know where your irrigation heads and lines are before we start. Know if you have a septic system and where the distribution lines run. If you're not sure, mark the areas of uncertainty and we'll work around them carefully.

Using the grade data, we design a set of finished elevations that achieve the drainage slopes the site needs. The primary targets are always the same: positive drainage away from the house foundation, no low spots that will trap water, and a smooth transition to neighboring grades at property lines and paved surfaces.

The International Residential Code minimum for foundation drainage is 6 inches of fall within the first 10 feet from the structure — that's a 5% slope. For the rest of the yard, we design to a minimum of 2% (about ¼ inch of fall per foot). On Houston's flat terrain, that sometimes means building up the area adjacent to the house with imported fill if the existing grade is already close to the street or property boundary elevation.

Before any subgrade work begins, we strip the topsoil from the work area and stockpile it. Topsoil is the dark, organic-rich layer at the surface — typically 3 to 6 inches on established residential lots in this area. It's what grass roots live in and what makes revegetation after grading work cleanly.

Topsoil should not be mixed into subgrade fill material. The organic content reduces its bearing strength and makes it compressible — you don't want it buried under a compacted fill section. Strip it, keep it separate, and bring it back at the end.

On jobs where the topsoil layer is thin or poor quality — common on recently developed lots that were scraped during construction — we may supplement with imported screened topsoil at the end. 4 to 6 inches of topsoil is the minimum for turf establishment. Less than that and you're fighting the sod every year.

With topsoil stripped and the cut/fill plan in hand, rough grading is the main earthmoving phase. Cut areas are excavated to design subgrade elevation and the material is either transported to fill areas on the same site, loaded out and hauled off, or a combination of both. Fill areas are built up in measured lifts — typically 6 to 8 inches per lift — rather than placed all at once.

On residential jobs, we use our mini excavator and skid steer to work in confined areas without excessive ground disturbance. Larger lots or more significant earthwork may use a track loader depending on volume and site access. The goal at the end of rough grade is to be within a few inches of design elevation everywhere, with the basic drainage shapes established.

Material that needs to leave the site — excess excavated clay, old fill material, roots — is loaded and trucked. We don't leave spoil piles on the property without a plan for where they go.

Compaction is where regrading jobs fail most often. Loose fill placed in a single deep layer will settle — not in a uniform way, but differentially, meaning some areas settle more than others. The result is new low spots that reappear within a year, which is exactly what the client paid to fix.

Proper compaction means placing fill in 6 to 8-inch lifts and mechanically compacting each lift before adding the next one. In Houston's clay soil, moisture content at the time of compaction matters — clay compacts best at or near its optimum moisture content (typically Proctor optimum, roughly the consistency of moist but not muddy soil). Clay that's too dry or too wet compacts poorly and is prone to settlement or swelling.

With rough grading done and compacted, the stockpiled topsoil goes back. We spread it at 4 to 6 inches across the work area, then fine grade — the process of refining the surface to eliminate depressions, smooth transitions, and bring the finished surface precisely to design grade.

Fine grading is done with a blade or box scraper at low passes, working across the slope direction to catch low spots. Any areas that need additional topsoil to achieve the design elevation get it at this stage. At the end of fine grading, the surface should be smooth, drain uniformly in the intended direction, and have no abrupt transitions that would catch mowing equipment or create trip hazards.

After fine grading, the surface gets raked smooth by hand along the house foundation and at any hard-scape transitions — driveways, sidewalks, patios — where machine work can't get clean without risk of damage. These transition zones matter for both appearance and function.

At the end of every grading job, we re-shoot grades with the laser level across the finished surface. This confirms that the as-built elevations match the design, that drainage slopes are positive and at or above the target percentage, and that no new low spots were created during the fine grading process.

This final check also catches any areas where topsoil spreading slightly altered the subgrade drainage direction. Topsoil placement can shift final grades by an inch or more in areas with thin lifts. The laser tells us before the job is called complete.
