When Has the Natural Terrain Posed a Significant Challenge in a Landscaping Project?
When the lay of the land tests the skills of landscape architects and company leaders, innovative solutions are key. From designing terraced garden walkways to sustainably renovating a hillside park, we've gathered five insightful examples from experienced Landscape Architects and Owners on overcoming natural terrain challenges in landscape architecture projects.

- Creating a Multi-Level Pool
- Enhancing Property with Bioswales
- Implementing Terracing and Retaining Walls
- Renovating Hillside Park Sustainably
Designing Terraced Garden Walkways
Designing and harnessing the natural terrain is always an opportunity in landscape design. One challenging project I completed was a terraced garden that connected resort villas to the beach, but the issue was a ten-foot grade change over a short distance. To address this, I designed a terraced garden that used gently sloped walkways and stairs to gradually guide resort guests from their tropical villas down to the beachfront.
Creating a Multi-Level Pool
We had a project in a suburban community where the backyard featured a steep ravine dropping over 15 feet down to a creek. The homeowners wanted an in-ground pool, but the topography posed significant challenges.
We designed a multi-level deck and pool that stepped down with the natural grade. Retaining walls stabilized the modified slopes and provided level areas for patios. The pool was situated at an angle, with one end at the top of the ravine and the other end at the bottom.
Rock excavation was extremely difficult. We cut into solid bedrock to create the pool basin. Boulders had to be jackhammered and removed by hand without damaging nearby utilities or the foundation of the house. It required precision work and close collaboration between designers and construction crews.
The finished pool appears to cascade down the hillside, integrating beautifully with the natural setting. What started as an obstacle became an opportunity to create a completely unique space. Challenging terrain often yields the most dramatic results.
Enhancing Property with Bioswales
I can share an experience we had with a property we purchased in the Lower Ninth Ward. The area's low elevation and poor drainage posed significant challenges.
We worked with local landscape architects to create a design that incorporated native plants and a bioswale system to manage water runoff. This not only addressed the flooding issues but also enhanced the property's aesthetic appeal. It was a great lesson in turning a challenge into an opportunity, and it significantly increased the property's value. The project really opened my eyes to the importance of working with the natural terrain rather than against it.
Implementing Terracing and Retaining Walls
When dealing with landscape architecture projects, one significant challenge often posed by natural terrain is steep slopes. Steep slopes can lead to issues with erosion and water runoff, which can undermine the stability of the landscape and any structures within it. To address this, we implement a combination of retaining walls and terracing to stabilize the ground and manage water flow effectively.
Retaining walls are constructed to hold back the soil and provide a flat surface for planting or construction. Terracing, on the other hand, creates multiple flat levels on the slope, which helps in reducing erosion and allows for more usable space. These terraces can be planted with vegetation that further stabilizes the soil and adds aesthetic value to the landscape.
We incorporate proper drainage systems to ensure that water runoff is controlled and directed away from critical areas. This might include the installation of French drains, swales, or rain gardens that help manage excess water. By combining these techniques, we can transform challenging terrains into functional and attractive landscapes while preserving the natural beauty and integrity of the site.
Renovating Hillside Park Sustainably
We had a project that involved renovating a hillside park with a steep slope that had caused extensive erosion and instability. The natural terrain posed challenges, but the design team focused on creating a sustainable and functional landscape while addressing the erosion problems.
To address the slope and runoff issues, the team implemented terraced levels with natural-stone retaining walls and native plants with deep-root systems to stabilize the soil. They also created switchback paths and used absorbent materials to make the park more navigable and manage water runoff.
Furthermore, a rain garden was installed at the base of the slope to capture and filter stormwater runoff, reducing erosion and improving water quality.
The innovative solutions transformed the challenging hillside into a sustainable and inviting space for the community.
