Drainage & Erosion in Roswell, Georgia
We redesign drainage on established properties where original grading can't handle a new pool, addition, or hardscape, routing water away from foundations and toward approved outfalls.

Drainage retrofits for Roswell's older lots
Roswell was built up decades before most of its neighbors, and it shows in the lot sizes — half-acre to five-acre parcels with mature hardwood canopy are common in neighborhoods like Horseshoe Bend, River Eves, and along Willeo Road. Many of these lots were graded under older standards and now need updated drainage as owners add pools, additions, or outdoor living space that the original grading never accounted for.
Adding another load of gravel to a washing driveway is a subscription, not a repair. Water is moving across your property along a route it chose. Our job is to give it a better one — sized correctly, armored where it needs to be, and invisible the rest of the year.

- Gravel drives that rut and wash after every heavy rain
- Standing water and soft ground near the house or barn
- Gullies cutting through pasture and hillsides
- Undersized or crushed culverts backing water up
Scope of work
How the work runs on a Roswell property
Watershed assessment
We map where water enters your property, how much of it there is, and where it wants to go before specifying anything.
Surface conveyance
Crowning, swales, diversion berms, rock check dams and dry creek beds that carry volume without cutting into the ground.
Culverts & subsurface drainage
Properly sized pipe, headwalls, catch basins, French drains and footing drains installed at the grade they actually need.
Slope stabilization
Regrading, riprap, matting and deep-rooted seeding to hold banks and cut slopes through the first two rainy seasons and beyond.
A property that handles a five-inch rain without you walking outside to look. No annual gravel bill, no soft ground, no new gullies.
Local conditions
What Roswell land does differently
StructuresRetaining Walls That Last: What Holds the Hill UpMetropolitan River Protection Act corridor
Property within Roswell's 2,000-foot river corridor faces added vegetation and impervious surface restrictions beyond standard buffers. We factor corridor review into any near-river project timeline.
Outdated drainage on established lots
Many Roswell homes were built before modern stormwater standards. Adding a pool, addition, or hardscape often requires retrofitting drainage the original grading never included.
Steep grades near Vickery Creek
Lots near the Vickery Creek gorge and historic mill district have significant elevation change, making retaining walls and careful erosion control necessary for any new construction.
Mature tree root systems
Decades-old hardwoods on established lots complicate excavation and grading. We plan cuts and fills to avoid damaging root systems that protect soil stability.
Questions
Roswell FAQs
What is the Metropolitan River Protection Act and does it affect my lot?
It's a state law establishing a 2,000-foot corridor along the Chattahoochee River with added restrictions on vegetation removal and impervious surfaces. If your property falls within that corridor, any grading, driveway, or structure work needs additional review before permits are issued.
Why does my older Roswell lot flood when newer neighborhoods don't?
Many established lots were graded to standards from decades ago, before current stormwater detention requirements existed. Adding hardscape or structures without updating drainage often overwhelms the original grading, which is why retrofits are common here.
Can I build a dock or deck near the Chattahoochee?
It depends on your exact distance from the river and whether the project falls inside the protected corridor. We coordinate with the appropriate review board early so the project isn't redesigned mid-permit.
How do you build retaining walls on Roswell's steeper lots?
We engineer wall height, drainage backfill, and footing depth to the specific slope and soil conditions, since undersized walls near the creek gorge fail within a few years. Taller walls typically require a permit and engineered plans.
What's involved in adding a pool to an established lot?
Beyond excavation, we typically need to redesign drainage around the pool equipment pad and regrade the surrounding yard so runoff doesn't pool against the house or neighboring property. Tree roots and utility lines often factor into the layout too.
Do mature trees limit what I can build?
Roswell's tree preservation rules protect certain specimen trees, and practically speaking, root systems on decades-old hardwoods limit how close excavation can safely happen. We map root zones before finalizing a grading plan.
