Expert Yard Grading & Sloping to Protect Your Property
Not every drainage problem starts underground. Sometimes gravity is simply working against your house instead of for it.
The Problem
Negative Slope and Low Lawn Bowls
Proper drainage design starts with a basic principle: the ground around your home should slope away from the foundation. When that slope is reversed — negative slope — water runs toward your house instead of away from it with every rain event.
Builder Shortcuts
In fast-moving developments around Lantana, Canyon Falls, and parts of Argyle, initial grading is sometimes done to pass a final inspection, not to hold up over years of clay movement.
Soil Settling
As expansive clay repeatedly swells and shrinks through wet and dry cycles, the ground around a foundation doesn't settle evenly — low spots develop naturally over time.
Landscaping Additions
New flower beds, patios, or retaining walls can unintentionally create a dam effect that redirects water toward the house.
The other common problem is a "low lawn bowl" — a depression where water collects and simply sits because there's no path out. These bowls kill grass, breed mosquitoes, and in soil as slow-draining as ours, can stay wet for days after a storm has passed. They're common on flatter lots around Lewisville and older sections of Flower Mound near FM 1171, where original grading didn't anticipate how little our clay soil actually absorbs.

The Solution
Swales and Strategic Re-Grading
Fixing a slope problem isn't just about adding dirt to a low spot — it requires understanding the full path water needs to travel across your property.
Drainage Swales
A shallow, gently sloped channel — subtle enough to mow over — engineered to guide surface water along a deliberate path away from your home toward an appropriate discharge point. Especially effective for the volume of water Denton County's intense summer thunderstorms produce.
Comprehensive Re-Grading
Laser-guided contouring re-establishes proper fall away from the foundation — generally a minimum slope of 6 inches of drop over the first 10 feet, adjusted for the specific lot. Grading levels and transit tools verify the result, so no hidden low spot undoes the work.
Working With Gravity, Not Against It
Combining accurate grade correction with swales where needed creates a permanent drainage path — into municipal storm drains or approved discharge points — that doesn't rely on pumps or ongoing maintenance, while staying mindful of Town of Flower Mound stormwater regulations.
In many cases, grading work is combined with a French drain or catch basins for a complete solution: grading handles surface water volume, while subsurface systems catch what the clay can't absorb quickly enough on its own. See how French Drains complement grading work →
Why grading isn't a DIY fix: Grading affects the entire water-flow pattern of your property — a change in one area can send water toward a part of your yard, or your neighbor's yard, that never had a problem before. Incorrect grading can also run afoul of Town of Flower Mound stormwater regulations if it concentrates runoff onto adjacent properties or into the right-of-way. A full evaluation of the lot's water flow should come before any grade change is recommended.

FAQ
Common Questions
How much slope should the ground have next to the house?
How much slope should the ground have next to the house?
A commonly cited guideline is about 6 inches of drop over the first 10 feet away from the foundation. Your lot and local requirements may differ, so confirm with a contractor.
Can regrading cause problems for neighbors?
Can regrading cause problems for neighbors?
Yes, if it sends concentrated water onto a neighboring lot or into the public right-of-way. A good plan accounts for where the water goes next.
Will grading alone fix my drainage problem?
Will grading alone fix my drainage problem?
Sometimes. If water also comes up through the soil or collects at low spots that can't be graded out, a French drain or catch basin may be needed too.
