How to Plan a Landscape and Retaining Wall Project for Sloped Yards

If your property sits on a hill or has uneven terrain, you’ve likely struggled with erosion, poor drainage, or wasted yard space. A well-designed landscape and retaining wall system can transform that challenging slope into a beautiful, functional outdoor environment. At Boss PDX, we specialize in helping Portland homeowners make the most of their outdoor spaces with integrated retaining wall and landscaping solutions.

Why Combine Landscaping with Retaining Walls?

Sloped yards require both structural support and thoughtful design. Installing a retaining wall helps hold back soil and create flat, usable terraces, while strategic landscaping ties it all together for visual appeal and long-term sustainability.

Prevent Erosion: A retaining wall stabilizes slopes and keeps soil in place.
Improve Drainage: Directs water away from foundations and prevents pooling.
Maximize Space: Turn steep grades into level patios, walkways, or garden beds.
Enhance Curb Appeal: Combine plants, lighting, and hardscaping for a polished look.

Steps to Plan Your Landscape and Retaining Wall Project

1. Evaluate the Slope

The first step is understanding how steep the slope is and how much soil needs to be retained. This determines the height, length, and number of walls required.

2. Choose Your Retaining Wall Material

Depending on your style and budget, popular options include:

Concrete blocks: Versatile, affordable, and great for curves or tiers.
Natural stone: Offers a rustic look and blends well with garden landscapes.
Poured concrete: Ideal for clean lines and modern landscapes.

3. Design the Landscaping Around the Wall

Once you establish the wall’s layout, plan plantings and hardscapes (like paths, stairs, or lighting) around it. Select low-maintenance, erosion-resistant plants like Oregon grape, sedum, or creeping thyme for sloped beds.

4. Address Drainage and Erosion

Drainage is critical on slopes. Incorporate weep holes, gravel backfill, and possibly a French drain system behind the wall to manage runoff effectively and avoid pressure buildup behind the wall.

5. Work with a Professional Contractor

For sloped landscapes, retaining walls over 3 feet high often require engineering and permits. Boss PDX ensures your wall is not only beautiful but also structurally sound and code-compliant.
