Case Study: A Two-Car Entrance in Arlington
Navigating DES Right-of-Way Permits to Engineer a Flawless Techo-Bloc & Marble Estate.
Phase 1: The 17-Foot Curb Cut Expansion
- The Arlington Restriction: Arlington County enforces notoriously strict zoning laws, utilizing the Department of Environmental Services (DES) to limit driveway aprons to a maximum width of 17 feet.
- The Parking Victory: We successfully secured the required Excavation Right-of-Way (ROW) permits to execute the maximum allowable curb cut expansion, dramatically improving the home's off-street parking.
- The Paving System: We removed a ruined, gravel-like asphalt strip and excavated deep. Everything was built on a 6-inch aggregate foundation topped with a structural concrete base. For the driveway surface, we utilized premium Techo-Bloc Blu 80 pavers (Smooth HD2 finish in Champlain Grey).
Phase 2: Hydrology & Drainage
- The Threat: The original driveway sloped heavily down the right side of the house. Arlington properties sit incredibly close together, and neighboring lots were already fighting severe water problems. The last thing we wanted to do was flood their yards with runoff from a widened driveway.
- The Solution: We engineered a total grading correction. From the house foundation forward, we leveled the driveway left-to-right, forcing all front water to safely exit into the street. Down the side of the house, we built up a structural walkway alongside a newly incorporated landscape bed to absorb runoff. Finally, we pitched the side walkway at a precise 2% slope to dissipate water harmlessly into the grass, while tying every downspout into a massive rear river-rock drainage basin.
Phase 3: Tundra Gray Marble & Structural Masonry
- The Front Entrance: The client originally wanted a traditional "Arlington Flagstone" look until they saw our Tundra Gray Marble. This thermal-treated, slip-resistant stone offers a spectacular modern aesthetic. We set the walkway stones tight together with zero grout joints, allowing a beautiful natural patina to form over time. A 4-foot connector pathway seamlessly bridges the marble walkway to the Techo-Bloc driveway.
- The Stoop & Walls: The original front porch was crumbling. We demoed it completely to the footer and rebuilt a bulletproof concrete block, rebar-reinforced core. The stoop was then veneered in Tundra Gray Marble and capped with massive 2-inch premium thermal Bluestone treads. To tie the estate together, we utilized Ledge Cut Stonington Ashlar for all vertical retaining walls, engineering the front planter wall to perfectly match the height of the first porch step.
The Tuck Standard: Turning a Problem into a Design Feature
When we moved to the rear of the property, we encountered a grading issue left behind by the home's original builder. The foundation and deck steps dropped much deeper into the earth than the new grade allowed. Instead of forcing the client to rip apart and rebuild their entire deck staircase, we engineered a custom solution. We created a gorgeous, subterranean landing at the bottom of the stairs, perfectly level with the bottom step. We wrapped the entire landing in a structural retaining wall equipped with a dedicated grate drain box. This didn't just solve the grading issue; it created a highly unique, four-sided "step-up" architectural feature that looks like a deliberate luxury design element.
