Yard Drainage Solutions in Marietta, GA
Marietta has decades of housing stock in one city, and the drainage problems track closely with when a neighborhood was built.
Marietta and the surrounding Cobb County neighborhoods include mid-century ranches near the Square, 1970s and 1980s split-levels through East Cobb, and newer infill throughout. Each era brings a different drainage pattern.
Older homes commonly have grade that has settled over fifty-plus years and original drainage that consists of a splash block. Newer construction is more likely to have pipe in the ground that has since silted, crushed or lost its outlet.
Cobb County ground conditions
The land around Marietta rolls, draining toward Sope Creek, Nickajack Creek, Rottenwood Creek and other tributaries heading for the Chattahoochee. Higher ground near Kennesaw Mountain falls away in several directions, and neighborhoods built along those slopes move a lot of water during a hard storm.
Soils are the familiar clay profile, with weathered rock closer to the surface in some areas. That matters for excavation: trench depth on a rocky lot is not always a free choice, and drainage design sometimes has to work with a shallower run than ideal.
Common Marietta drainage complaints
Negative grade at the foundation
On homes forty or fifty years old, backfill has settled and the ground now leans toward the house. Regrading the first few feet of perimeter is often the first correction.
Crawl space moisture
Many local homes are on crawl foundations. Roof discharge at the wall and settled grade are the usual exterior sources, and both are addressable outside the house.
Sloped driveways feeding the garage
Split-levels and hillside lots often have driveways that drop toward a lower garage, which sends storm flow straight at the door.
Old pipe with no cleanouts
Existing corrugated lines from earlier decades frequently have sags, sediment and no access point, so diagnosis usually starts at the outlet.

Questions
Marietta Drainage FAQs
My Marietta house is from the 1970s and never had drainage problems until recently. What changed?
Usually the grade. Foundation backfill compacts over decades, gradually flattening or reversing the slope that originally moved water away. Added landscaping, new beds and mulch buildup along the wall can contribute as well.
Can drainage work help a damp crawl space?
Exterior work targets the water sources: roof discharge, grade and subsurface flow toward the wall. That often reduces moisture substantially. Interior conditions such as vapor barriers and ventilation are a separate scope.
Is rock a problem for trenching in Cobb County?
It can be. Some areas have weathered rock relatively close to the surface, which limits trench depth and may push the design toward surface capture and grading rather than a deep drain.
