Mari Landscaping installed this backyard retreat in San Lucas, about 45 miles north of Paso Robles. Decomposed granite pathways wind through the open oak-filled oasis, with Mediterranean climate plants woven in between. Multiple grape-covered arbors provide a shady escape from the summer sun. Many other hardscape elements including paver and flagstone paths, mortarless retaining walls and and railroad tie steps, help create harmony between the built landscape and the surrounding oak woodland.
