One of the most common conversations we have with Westlake Village homeowners goes something like this: "We love the house, but we can't use half the backyard because of the slope." It is a familiar story in this part of the Conejo Valley, where the rolling hillside terrain that makes the area so scenic also makes flat, functional outdoor space a premium. The solution — a combination of engineered retaining walls, level paver platforms, and connecting walkways — is one of the most satisfying transformations in all of residential hardscape design. Here is a complete guide to making it work on your property.
Why Sloped Yards Need More Than Just a Patio
A paver patio built on unstable, unaddressed slope is a patio that will eventually shift, crack at the edges, and drain poorly. The ground beneath it wants to move, and without a structural retaining element to hold the soil in place, it will. Retaining walls solve this problem at the source. They hold back the hillside, create a level sub-base for hardscaping, and manage the flow of groundwater so it exits in a controlled direction rather than saturating the soil behind your patio and causing subsidence. In short, the retaining wall is the foundation that makes everything else possible. Learn more about our approach on our retaining wall installation service page.
Understanding the Two Roles a Retaining Wall Plays
Retaining walls serve a structural role and an aesthetic one simultaneously, and the best designs do both brilliantly:
- Structural: The wall physically holds back the soil above or below the cut, preventing erosion and slope failure. This requires proper drainage — a gravel backfill layer and perforated drain pipe — behind every wall to relieve hydrostatic pressure, which is the number one cause of wall movement and bulging over time.
- Aesthetic: The wall is a visible design feature. We offer textured segmental block systems in a range of earth tones, as well as natural stone stacked-wall styles, so your retaining wall looks like it was designed alongside your home rather than added as an afterthought.
Designing a Multi-Level Backyard: The Three-Zone Approach
When we approach a significantly sloped backyard in Westlake Village, we typically think in three zones that stack up the hillside:
Zone 1: The Lower Entertainment Level
This is the primary gathering space closest to the house — the zone where you put your main patio, outdoor dining area, and potentially an outdoor kitchen or fire pit. It should be as large as the slope allows after the first retaining wall cut, and it should connect directly to interior living spaces through sliding or French doors for seamless indoor-outdoor flow. Our paver patio installation team handles this zone, typically using travertine or large-format concrete pavers for a refined, durable surface. If an outdoor kitchen is part of the vision, our outdoor kitchen and fire pit hardscape team integrates those structures at the same time so paver work around them is perfectly flush and coordinated.
Zone 2: The Middle Transition Level
A second retaining wall creates a middle terrace that might serve as a planting bed, a lawn panel for kids or pets, or even a second seating area with a fire pit focal point. The height of this wall depends on the overall grade change — for steeper properties, we incorporate geogrid reinforcement layers anchored back into the hillside for added structural strength. Cap stones are set with masonry adhesive for a clean finished top that also keeps debris from lodging between blocks.
Zone 3: The Upper Slope or Garden Level
The topmost level is often left as a natural slope, a planted garden terrace, or — on larger properties — a third usable platform. A small retaining wall or boulder edging at this level manages runoff from above, preventing heavy rain from washing soil down onto your lower patios. Homes throughout Lake Sherwood and the hillside streets of Westlake Village frequently have this three-zone configuration.
Connecting the Levels: Paver Staircases and Walkways
Level zones without safe, attractive connections between them are incomplete. Paver staircases — built from the same material as the surrounding patio for visual continuity — provide the link. Steps are typically 6 inches tall (rise) and 12 to 14 inches deep (run) for comfortable, safe footing. We integrate lighting channels into stair risers during construction so the steps are visible and inviting after dark with minimal additional work. Our paver walkway installation service handles the connecting paths between levels, including curved approaches that follow the natural contour of the hillside rather than cutting straight lines across it. Homeowners in Agoura Hills and Oak Park with similarly rolling terrain have used this approach to create backyard environments that feel like resort properties.
Pool Decks on Sloped Properties
Many Westlake Village homes with sloped lots also have pools — and a pool on a slope creates additional challenges around drainage and deck levelness. Our pool deck paver installation team works closely with the retaining wall crew on these projects to ensure the pool surround drains correctly (typically one-quarter inch per foot away from the pool edge), that coping pieces are precisely cut with no trip hazards, and that the deck surface transitions cleanly into the surrounding patio levels. Travertine is particularly popular for hillside pool decks because it stays cool underfoot and its natural color variation hides the occasional splash stain.
How Long Does a Full Terracing Project Take?
A full backyard terracing project — two retaining walls, a main paver patio, a secondary terrace, connecting steps, and a pool deck — typically takes between ten and eighteen days depending on the size of the slope, the amount of excavation required, and the complexity of drainage work. We provide a detailed timeline in every estimate so you can plan landscaping, planting, and furniture delivery around our schedule. Mini-excavator access is required for most hillside projects; we assess site access during the free estimate to identify any constraints before work begins.
