Tiered Retaining Walls Turned This Chesterfield Hillside Into Planting Space

A steep, overgrown hillside occupied a large portion of this Chesterfield backyard but provided little usable value and was difficult to maintain. Instead of treating the slope as one continuous area, Excel Landscaping divided it into multiple levels with tiered retaining walls, integrated steps, and defined planting beds, creating a cleaner hillside that homeowners could access, maintain, and gradually incorporate into the surrounding landscape.

Tiered Retaining Walls

Walls, steps & planting beds

Chesterfield, MO

Residential hillside project
BEFORE & AFTER RESULTS

From Overgrown Hillside to Tiered Planting Space

Before:
Tiered retaining walls divide the hillside into defined levels, with integrated steps providing access and planting beds creating a cleaner, more manageable landscape.
After:
The completed retaining wall holds back the hillside while creating a wider level area, with steps connecting the upper and lower backyard.

How Tiered Retaining Walls Made This Hillside Easier to Use

A steep, heavily overgrown hillside occupied a large portion of this Chesterfield backyard. Although the slope was a major visual part of the property, it was difficult to maintain and gave the homeowners little opportunity to use the area for intentional landscaping. Clearing the vegetation alone would have exposed the same continuous slope, so the project needed a way to organize the grade rather than simply improve its appearance.

A tiered retaining wall system made it possible to work with the existing elevation while dividing the hillside into more manageable levels. Instead of treating the slope as one large area, the walls create defined sections that follow the grade of the property. That gave the homeowners something the original hillside did not provide: dedicated planting areas that could be maintained and landscaped individually.

Once the layout was established, the overgrown portions of the hillside were cleared and prepared for the new retaining-wall system. Multiple wall sections were constructed at different elevations using segmental retaining wall block and matching caps. The stepped layout follows the shape of the hillside while creating a consistent finished appearance across the different levels.

Access also needed to remain part of the design. Steps were incorporated between the retaining-wall tiers so the homeowners could move through the hillside rather than having the new walls create barriers between elevations. The open areas behind and between the wall sections were then finished as defined planting beds, with landscape mulch completing the newly organized areas.

The completed project included:

  • Clearing the overgrown hillside for the new layout
  • Multiple retaining-wall tiers constructed at different elevations
  • Segmental retaining wall block with matching caps
  • Integrated steps connecting the hillside levels
  • Defined planting beds between retaining-wall sections
  • Drainage aggregate incorporated into the retaining-wall construction
  • Landscape mulch finishing the planting areas
  • Completion in approximately two working days

The advantage of the tiered layout is that it organizes the existing slope without eliminating the property’s natural elevation. Each retaining-wall section helps define a smaller portion of the hillside, while the steps keep the different levels accessible. The planting beds also give the homeowners room to add landscaping over time rather than trying to maintain one large, uninterrupted slope.

The finished backyard now has a much clearer structure. What was previously an overgrown hillside is now a series of defined retaining-wall tiers, accessible steps, and planting areas that make the slope easier to maintain and easier to incorporate into the rest of the landscape. The project did not need to flatten the hillside to make it more useful; it needed to give the existing grade a more intentional layout.

Why this solution worked

The tiered layout worked with the existing grade instead of treating the hillside as one continuous slope. Breaking the elevation change into multiple retaining-wall levels created defined planting beds and allowed steps to connect the different areas. The homeowners gained a cleaner, more manageable hillside while preserving the natural elevation of the property.
