Dallas Grading and Resloping for Drainage Problems

Dallas-area properties may contain heavy clay, fill soil, rock, limestone, or mixed materials. Clay can hold water near the surface and can expand or shrink as moisture changes. That movement affects how yards, walkways, patios, retaining features, and drainage paths behave over time.

Short, intense storms can also expose a grading problem quickly. A slope that seems acceptable during dry weather may send water toward a foundation during a heavy rainfall. Water may cross a narrow side yard, collect behind a fence, or concentrate at the bottom of a driveway.

The contractor should consider existing grades, soil type, available outlet, structures, trees, utilities, fences, easements, and neighboring properties. A solution that redirects water onto another lot or toward a public sidewalk can create a new problem instead of solving the original one.

A swale is a shallow, shaped depression that guides water across a property. It can be useful when there is enough room to carry water toward an approved outlet without creating a hazard or damaging another property.

Resloping may be combined with surface drains, catch basins, channel drains, downspout extensions, or underground piping. In some yards, a drainage system is necessary because there is not enough room or elevation difference to solve the problem with soil alone.

Grading should work with the drainage system, not fight it. A contractor should explain where collected water will discharge and whether that point is suitable. Do not assume that sending water to the street, alley, storm sewer, or a low neighboring area is automatically allowed.

Drainage installations are their own scope. If a project needs French drains, catch basins, pumps, or significant piping, confirm whether those items are included or whether a separate drainage contractor is required.

A common residential problem is a slope that falls toward the foundation. Regrading may involve removing soil near the wall, adding soil farther away, reshaping side yards, or creating a defined path for runoff.

The work must protect foundation clearances, siding, doors, windows, vents, steps, air-conditioning equipment, utility connections, and existing landscaping. Simply piling soil against a wall can create moisture and maintenance problems.

Grading is not foundation repair. If there are cracks, movement, settlement, water intrusion, or structural concerns, consult the appropriate foundation or structural professional. The grading contractor can address surface water and soil elevations, but should not promise that regrading will repair a structural defect.

For new homes and commercial projects, grading should follow the survey, civil plans, drainage plan, geotechnical recommendations, and proposed elevations. The scope may include mass grading, building-pad elevations, access routes, stormwater features, utility corridors, and final site contours.

Dallas’s current paving and grading checklist identifies requirements that can include a site plan, proposed topography, drainage information, tree documentation, and permits depending on the property and project. It also states that a grading or paving permit does not itself function as a tree-removal permit.

Requirements may differ outside Dallas city limits. Confirm the applicable municipality before relying on a Dallas-specific checklist.

Changing grade near a property boundary requires care. Water cannot simply be pushed toward a neighbor because that is the easiest direction. Fences may not mark the exact legal boundary, and an easement may restrict what can be built or changed.

Ask whether the work requires a grading, paving, drainage, erosion-control, escarpment, or other approval. The answer depends on the property, project size, location, and connection to public infrastructure. A contractor should identify permit assumptions in the proposal rather than saying that all grading is exempt or all grading requires the same permit.
