Hillside yards need a company that builds walls for a living
Sandy Springs is where our retaining wall work is. The lots between Roswell Road and the Chattahoochee were graded steep, the 1960s ranch neighborhoods off Glenridge and Johnson Ferry drop away behind the house, and Riverside and Huntcliff have some of the biggest grade changes inside the Perimeter. We’re based fifteen minutes away in Dunwoody, and a good share of the walls, terraces and drainage systems we’ve built in the last three years are on the Sandy Springs side of Peachtree Dunwoody Road.
Everything we run is electric and solar-charged. On a two-week wall job that means no gas engine idling next to your neighbor’s bedroom window, which in a city that regulates contractor hours is worth something.

What we build in Sandy Springs
Retaining walls. Modular block (Belgard, Allan Block), natural boulder, poured concrete, and timber replacement. Sandy Springs has the clearest wall rules in the area: a wall four feet or less from the bottom of the footing to the top, with nothing pushing on it from above, is exempt from a permit; four to six feet needs a permit and an owner’s indemnification; six feet and up needs a signed and sealed engineered design. We handle the permit, the footing inspection and the final. Retaining Walls
Terracing and slope repair. Two or three short walls with planted terraces between them often look better and cost less than one tall engineered wall. On slopes too steep to plant we install Dirt Locker systems and native grasses that hold the bank.
Paver and stone patios. Belgard and Techo-Bloc pavers, bluestone, flagstone, permeable systems where runoff is the issue. Paver Patios
Drainage. Every stream in Sandy Springs runs to the Chattahoochee, and the city’s 75-foot buffer (25 feet state, 25 feet city, 25 feet impervious setback) limits what can go near the water. Away from the creeks the problem is the same red clay as everywhere else: French drains, underground downspout runs, catch basins, dry creek beds, and regrading yards that slope toward the house. Drainage and French Drains
Outdoor kitchens and fire features. Gas or wood fire pits, built-in grills, counters in stone veneer or block.
Planting. Sandy Springs is a Bee City USA affiliate and its own landscape plan leans on the Georgia Native Plant Society list. So do we: oakleaf hydrangea, fothergilla, Piedmont azalea, butterfly weed, little bluestem, river oats along the wet spots.
Quiet electric maintenance and lawn care. Weekly and bi-weekly service, fertilization, weed control and pest control with an organic option for each. The city allows commercial landscaping Monday through Friday 7:30 a.m. to 7:30 p.m. and Saturday 8 to 5, none on Sunday; our crews fit inside the window without anyone noticing.
Commercial grounds. Medical office buildings around Pill Hill, small office parks off Hammond and Peachtree Dunwoody, HOA entrances in the swim-tennis neighborhoods. Commercial Maintenance
Sandy Springs yards, specifically
The grade. Glenridge Hammond (about 500 homes, 1957–65, mostly brick ranches), Amberidge, North Harbor, Devonwood and the streets around North Springs were built on rolling ground and the back yards fall away. That’s why so many of them have a failing timber wall from the 1980s and a patio nobody uses because it’s on a slope.
Trees. We design walls and patios around the big oaks, not through them.
Rear-yard grading. Development Code 9.4.3 limits how much you can regrade a back yard. Terracing with walls is the usual way through it.
The river. If you’re inside the buffer near the Chattahoochee or one of its creeks, nothing gets built within 75 feet and nothing gets disturbed within 50. Landscaping in the outer band is sometimes allowed. We’ll tell you before you spend money on a design.
What Sandy Springs clients say
“I used Oak Avenue for retaining wall replacement and was very satisfied with the excellent planning and execution. Jorge and his team were professional, punctual, and friendly. I highly recommend them and will use their services again in the future.” – Yamato M.
Trees and canopy, which is the other permit
Most people planning a wall or a patio in Sandy Springs know to ask about the wall permit. The tree rules catch more projects than the wall rules do, so it is worth knowing where the lines are before anything is drawn.
The thresholds. A permit is needed to remove a hardwood eighteen inches across or larger, and the bar drops to ten inches for dogwoods and redbuds because the city protects understory flowering trees specifically. Anything inside a stream buffer needs approval whatever its size. Those numbers are measured at chest height, and they are smaller trees than people picture.
The canopy floor. Sandy Springs holds residential property to a minimum canopy coverage, and when a lot drops below it after a removal the shortfall is settled with a per-tree contribution to the city’s tree fund or with replacement planting on site. Replanting is almost always the better outcome, and on a sloped lot it is also the cheaper one, because roots are doing structural work for you whether or not you were thinking about them that way.
What that means on a hillside build. A retaining wall wants a clean excavation and a compacted base. A big oak twenty feet upslope wants nobody touching its roots. Those two things are in tension, and pretending otherwise is how walls end up leaning and trees end up dying two summers later. We work it out at the design stage: shift the wall line, step it, hand dig the section inside the drip line, or in a few cases tell you the wall you want is not worth the tree it costs.
Root protection during the build. Fencing off the root zone, keeping the plate compactor and the loaded wheelbarrow route outside it, and not stockpiling soil or stone on top of it. It looks fussy on day one. It is the difference between a mature tree and a stump grinding invoice.
The first thirty days after a planting
A planting job on a slope succeeds or fails in its first month, and almost all of that is water. Georgia’s watering rules and gravity are both working against you, so here is how we handle it.
The state’s watering window, and the exemption that matters. Outside of drought restrictions, outdoor watering in Georgia is allowed between four in the afternoon and ten in the morning. New plantings are exempt for their first thirty days, and drip lines, soaker hoses and hand-watering with a shut-off nozzle are exempt any time of day. So the answer to the question everyone asks is that yes, you can water your new plants at noon in July, and after a month you go back to the window like everyone else.
On a slope, when you water matters less than how. Water applied fast to a Sandy Springs hillside runs off before it soaks in, and what you get is a wet driveway and a dry root ball. Drip emitters and soaker lines put it down slowly enough that the clay can take it. That is not a premium upgrade on a sloped planting, it is the thing that makes the planting work.
Mulch is doing structural work. Two to three inches, kept off the trunks and the stems, holds moisture in, keeps the soil temperature steady and stops the first hard rain from moving your topsoil down the hill. On steep sections we will use a coarser shredded mulch that knits together rather than a fine one that floats.
Ivy, privet and the rest. Sandy Springs spends real effort pulling English ivy, privet, nandina and Chinese wisteria out of Big Trees Forest Preserve, Lost Corner and Ridgeview Park, and there is no point in the city doing that while the same plants climb the oaks in your back corner. Ivy up a trunk is a slow strangling, and it is one of the few yard problems where doing nothing genuinely gets worse every year. We cut it at the base, clear a ring, and come back for the regrowth rather than pretending one pass finished it.
One small rule worth knowing. Grass over ten inches tall is a code violation in Sandy Springs, which surprises owners of rental and between-tenant properties more than anyone else. If a property is going to sit empty for a stretch, that is worth a conversation before the letter arrives rather than after.
Questions Sandy Springs homeowners ask us
When does a Sandy Springs retaining wall need a permit? Not if it’s four feet or under from the bottom of the footing to the top and nothing is loading it from above (a driveway, a slope, a fence). Four to six feet: permit plus an owner indemnification. Six feet and taller: permit plus an engineered, sealed design. Replacement walls follow the same rules. We file it.
Can you replace a timber wall with block without a permit? If the new wall stays at or under four feet with no surcharge, yes. Most of the timber walls we replace are taller than that once you measure from the footing, so plan on the permit.
My back yard floods from the neighbor uphill. What fixes it? Usually an interceptor French drain along the property line tied to a discharge point downhill, sometimes with a catch basin. If the yard slopes toward the house, regrading is part of it.
Is electric equipment strong enough to build a wall? Yes. Our compaction, cutting and excavation tools are commercial battery equipment. You’ll notice the quiet; you won’t notice a difference in the wall.
When are you allowed to work? Weekdays 7:30 to 7:30, Saturdays 8 to 5, never Sunday. We schedule inside that.
Do you serve the whole city? Yes: Riverside, Huntcliff, North Springs, the Panhandle, Glenridge, Perimeter Center and everything between.
Nearby
Sandy Springs sits on the far side of Perimeter from our base in Dunwoody. We also work Brookhaven, Chamblee, Doraville and Peachtree Corners, and the office parks in between are covered on the Perimeter Center commercial page. By service: drainage, French drains and grading, eco-friendly lawn care, fertilization, weed and pest control.
Three of those trades now have a Sandy Springs page of their own, with the city’s permit thresholds and the way we actually build written out in full: retaining walls, paver patios, and outdoor kitchens and fire features.
Front yards on the Glenridge and North Springs side fall away from the street steeply enough that the approach to the door is a flight of steps rather than a walk, and steps are the one piece of hardscape where the numbers are not a matter of taste. How we set risers, landings and lighting on a sloped approach is covered on our steps, walkways and driveways page.
One more thing worth flagging for Sandy Springs in particular: if the reason you are calling is the lawn rather than the hardscape, we keep a separate page on eco-friendly lawn care in Sandy Springs. It covers the creek buffers, brown patch in fescue, getting an old irrigation system to use less water, and the city work-hour rules, which matter more to a weekly mowing visit than to a one-off build.
