Drainage & Erosion in East Cobb, Georgia
Lots graded decades ago rarely match current stormwater volumes. We redesign swales, catch basins, and pipe runs to handle today's rainfall without flooding basements or neighboring yards.

Re-Engineering Outdated Drainage
East Cobb is unincorporated Cobb County, which means larger minimum lot sizes, deeper setbacks, and some of the most established tree canopy in metro Atlanta. Neighborhoods like Indian Hills, Sewell Mill, and the Providence Road corridor sit on rolling ground that drops toward Sope Creek and, further west, the Chattahoochee River bluffs.
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.

Scope of work
How the work runs on a East Cobb 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.

What East Cobb land does differently
StructuresRetaining Walls That Last: What Holds the Hill UpAging retaining structures
Many East Cobb lots have decades-old timber or unengineered block walls that are now failing. We assess whether to rebuild in place or redesign the slope entirely, factoring in soil load and drainage.
Sope Creek and tributary buffers
Lots backing to Sope Creek or its tributaries fall under state stream buffer protections. Any grading or clearing near these waterways needs a buffer survey before design work starts.
Established tree root systems
Fifty-year-old hardwood canopies mean root systems extend well beyond the drip line. Excavation for walls or drainage has to route around roots that can undermine a structure or damage a mature tree if cut carelessly.
Renovation-driven drainage changes
Additions, pool installs, and expanded patios change how water moves across a lot that was graded for a smaller footprint originally. We re-engineer drainage whenever impervious surface increases meaningfully.
Questions
East Cobb FAQs
My retaining wall is bulging. Should I repair or replace it?
A bulging wall almost always signals inadequate drainage behind it, not just a cosmetic problem. In most East Cobb cases we recommend full replacement with proper backfill and drainage rather than patching a wall that will fail again.
Is East Cobb inside city limits or unincorporated county?
East Cobb is unincorporated Cobb County, which means it follows county zoning and permitting rather than a city government. Lot size minimums and setback rules tend to be more generous than in nearby incorporated cities.
How close to Sope Creek can I build or grade?
State stream buffer law generally requires a minimum undisturbed buffer along the creek, with additional Cobb County requirements in some zones. We survey the exact buffer line for your parcel before finalizing any site plan.
Why does my basement flood during heavy storms?
Older East Cobb lots were often graded to standards that predate today's rainfall intensity and additional hardscape. Regrading the slope away from the foundation and adding a French drain system typically resolves it.
Can you preserve mature trees during a retaining wall install?
Yes, that's usually the priority. We hand-dig near root zones when necessary and adjust wall footing location to avoid major roots, though some root pruning is sometimes unavoidable.
What's a realistic timeline for a full drainage overhaul?
A comprehensive drainage redesign on a typical East Cobb lot, including grading and pipe work, generally takes three to six weeks depending on lot size and how much of the yard is affected.
