Cobb County Land Work
Marietta pairs historic in-town lots with sprawling estate parcels near Kennesaw Mountain and the Chattahoochee. We build for both.

Marietta is a county seat with a split personality: dense, established neighborhoods around the historic square and Marietta Square, and larger wooded parcels pushing north toward Kennesaw Mountain National Battlefield Park and west toward the Chattahoochee River. Both markets bring their own grading and access questions before a design ever gets drawn.
The clay-heavy red soil common across Cobb County holds water longer than it should, which shapes how we plan driveways, retaining walls, and outdoor living spaces on sloped lots in neighborhoods like Indian Hills, Sandy Springs-adjacent Vinings, and the East Cobb line. Older tree canopy and mature root systems also factor into every excavation plan.
We work directly with Cobb County's Community Development Agency on permitting, land disturbance permits over the county's one-acre threshold, and stream buffer requirements tied to Sope Creek, Nickajack Creek, and the Chattahoochee River corridor. That local process knowledge keeps projects moving instead of stalling in review.
What makes this market different
Properties near the Chattahoochee National Recreation Area boundary fall under state and county stream buffer rules that limit clearing and grading near the water. We map buffer lines early so site plans don't require rework later.
Cobb County's dense red clay sheds water fast and erodes on any exposed slope. We design swales, French drains, and terracing that account for clay compaction rather than fighting it after the fact.
Marietta's tree ordinance protects specimen trees on many lots, especially in older neighborhoods. We plan access roads and grading to save qualifying trees and avoid fines or replanting mandates.
Many Marietta lots sit on septic systems or older utility lines installed decades ago. We verify existing infrastructure before any driveway or foundation work begins so we're not cutting into something undocumented.
Featured services
From half-acre in-town parcels to five-acre wooded tracts near Kennesaw Mountain, we handle grading plans, land disturbance permitting, and phased clearing that respects Marietta's mix of zoning categories.
Land DevelopmentWe install french drains, dry creek beds, and grading corrections built for Cobb County's compacted clay, which sheets water rather than absorbing it. This protects foundations and neighboring lots downhill.
Drainage & ErosionMarietta's rolling terrain near Kennesaw Mountain and the river bluffs calls for engineered retaining walls, not stacked block. We design walls rated for the loads and drainage conditions of each specific slope.
Retaining WallsLong driveways cutting through wooded Cobb County lots need proper base prep and cross-drainage to survive clay soil movement. We grade for water first, aesthetics second.
Driveways & AccessMarietta homeowners often want to reclaim mature, shaded backyards for patios, fire features, and pool decks. We design around existing trees and grade changes instead of clear-cutting yards.
Outdoor LivingFrom historic-district-compatible wood fencing to full perimeter fencing on larger acreage near the county line, we match materials and layout to the neighborhood context.
Fencing & EntriesWe coordinate grading, planting beds, and hardscape into one cohesive plan so a Marietta property reads as intentional, not pieced together over multiple projects.
Property PlanningLarger Cobb County parcels near the Cherokee County line increasingly add detached garages, workshops, and storage barns. We site these structures to satisfy setback and drainage rules.
Barns & OutbuildingsProperty types
Established parcels near the Marietta Square with mature trees, tighter setbacks, and heritage tree protections that shape any grading or hardscape work.
Larger lots near Kennesaw Mountain and toward the Cherokee County line, often one to five acres, with rolling grade and significant tree canopy.
Homes near the Chattahoochee River corridor that require buffer compliance and careful erosion control on any disturbed ground.
Newer high-end subdivisions with engineered lots that still need custom drainage and retaining solutions beyond the builder's original grading.
Why owners choose us
We walk the land with you, read the topography and water, and separate what the site needs from what it would merely be nice to have.
Access, drainage, building envelopes and structures get planned together, with a phasing order that protects the budget.
Drawn plans for grading, walls, fencing, barns and landscape so every trade builds from the same document.
One crew and one point of contact, working the plan in the sequence that keeps finished work from being torn back out.
We walk the property after the first heavy rain, confirm everything drains and functions, and hand over a maintenance plan.

ViewField notes
A leaning wall is almost never a block problem. It's water pressure behind a wall that had nowhere to drain — and it was decided the day the base was cut.
ReadDrainageIf you're buying three loads of gravel a year, you don't have a gravel problem. You have a water problem, and gravel is the most expensive way to ignore it.
ReadOutdoor LivingOn acreage, outdoor living isn't a patio behind the house. It's choosing which part of the property to make habitable — and building the ground under it properly.

Cobb County requires a land disturbance permit for most grading projects over a certain threshold, and any work near a stream buffer triggers additional review. We handle the application and plan review process as part of our scope.
The city and county both protect specimen and heritage trees above a certain diameter. We survey protected trees before design and adjust driveway or structure placement to avoid removal fees and mandatory replanting.
Cobb County's red clay compacts and sheds water instead of absorbing it, so poorly graded lots pool water fast. We typically fix this with regrading, French drains, or a combination of swales and dry creek beds depending on the slope.
Yes, but any work within the state-mandated buffer requires careful setback compliance and often coordination with the county. We map the buffer line first and design around it rather than requesting variances.
Most Marietta retaining walls require engineered drainage behind the wall, not just block and gravel, because of how the clay holds water. We design wall height, batter, and drainage together, then pull permits where required.
A straightforward driveway regrade with new base and drainage typically runs two to four weeks depending on length and slope, though longer wooded driveways with significant grade change take more time.
Many established neighborhoods, especially those outside city water and sewer lines, still run on septic. We locate and mark septic fields before any excavation to avoid damaging the system.
Expect dense red clay with variable rock content, especially near Kennesaw Mountain. This affects everything from footing depth to how quickly water drains, or doesn't, after grading.
Yes. Sloped lots in that area are common and buildable, but they require terracing, retaining structures, and careful erosion control during construction to prevent slope failure.
Yes. We work on quarter-acre historic district lots and multi-acre wooded parcels alike, adjusting our approach for each site's zoning, tree canopy, and drainage pattern.
