Many hillside homeowners in the Bay Area have at least one section of their backyard they consider unusable. Either the land is too steep to use, too unstable to build on, or too expensive to fix without a clear plan. The good news is that your property probably has more workable space than you think. In this article, we walk through the best ways to design a backyard for hillside properties.

The Challenges of Landscaping Sloped Properties

Most of the problems on a hillside lot come down to two things: water moves soil downhill, and flat ground is hard to come by. Bay Area winters make the first problem worse over time, as heavy rains wash soil away and can make slopes even more dramatic. To address these challenges, landscape architects use a combination of techniques to stabilize the slope and create usable space that can accommodate landscaping and hardscaping improvements.

How Landscape Architects Turn Hillside Properties into Attractive Backyards

Retaining Walls

If your yard has a significant slope, retaining walls are likely where your design should start. These installations hold back soil, prevent erosion, and create level ground for patios, gardens, and other design features. A skilled designer can build a retaining wall to feel like an intentional focal point or to blend naturally into the surrounding landscape.

Multi-Level Terracing

Terracing takes a slope that is too steep to use and turns it into a series of flat, functional levels. These tiers make it possible for different areas of the yard to serve different purposes. You can have a dining area on one, a garden on another, and a fire pit on the next. It is one of the most effective ways to maximize the potential of a hillside property.

Deck 

When terracing isn’t an option, a deck is often the next best solution for gaining usable space on a hillside lot. A deck sits over the slope on a post and beam structure, which eliminates the need to move soil or regrade the land. When attached to your home, an elevated deck makes the transition between indoors and outdoors feel natural while adding functional square footage for seating areas, shade structures, and outdoor kitchens.

Drainage Planning

Rainwater moving down a slope strips topsoil, collects behind retaining walls, and saturates the ground beneath patios and structures. Landscape architects address this by shaping the gradient to direct surface runoff, adding channels that slow water before it picks up speed, and installing perforated pipes behind retaining walls to relieve pressure before it builds.

Plant Selection

To choose the right plants for a hillside property, you must consider root depth and water needs. Deep-rooted plants hold soil in place between hardscape elements and reduce surface erosion over time. Drought-tolerant plants require less watering to thrive, which is important because over-irrigation can cause the same erosion issues as heavy rain.
