Retaining Walls Built for Colorado's Terrain

Colorado Springs sits along the Front Range where the Great Plains meet the Rocky Mountains. That transition creates the sloped, uneven terrain that makes retaining walls one of the most common landscaping needs in El Paso County. Whether you need to level a yard, prevent hillside erosion, create usable terraces, or protect a home from soil pressure, a properly engineered retaining wall is the solution.

CN Landscaping installs retaining walls throughout Colorado Springs, Monument, Falcon, Fountain, Black Forest, Larkspur, and Perry Park. In Falcon, where large lots at Meridian Ranch and Woodmen Hills often sit on sandy, wind-exposed terrain with significant grade changes, retaining walls create level outdoor spaces and prevent erosion on exposed slopes.

Wall design must account for drainage, frost conditions, soil, slope, surcharge loads, and the selected wall system. Base depth, footing detail, backfill, filter fabric, drains, and reinforcement are determined for the site and coordinated with manufacturer requirements, local code, and stamped engineering when required.

Understanding the Difference — and Why It Matters

Wall height, length, soil pressure, drainage, material, access, demolition, and engineering requirements shape the final scope.

Structural retaining walls hold back soil that would otherwise slide, erode, or put pressure on homes or structures. These walls bear lateral load and must account for soil pressure, water pressure, and surcharge loads such as driveways, structures, or equipment above the wall. Permit and stamped-engineering requirements depend on the jurisdiction's measurement rules, total retained height, loading, slope, drainage, and nearby improvements.

Decorative retaining walls create garden terraces, raised planters, seating walls, and visual interest. While they still retain some soil, the loads are typically lower — often under 2 feet of retained height. These walls do not usually require permits or engineering, but they still need proper drainage and base preparation to last in Colorado's climate.

Many projects include both types. A common Colorado Springs design uses a structural wall to level a sloped backyard, then adds decorative terrace walls and seating walls above it to create usable outdoor living areas. CN Landscaping evaluates every project to determine the right approach and coordinates with structural engineers when required.

Why Retaining Walls Fail in El Paso County — and How We Prevent It

El Paso County's geology creates specific challenges for retaining wall construction that contractors from other regions often underestimate. Here is what we engineer for on every project.

Expansive clay soils: The clay soils throughout Colorado Springs swell up to 10% when wet and shrink when dry. This expansion pushes against retaining walls with tremendous force. We use a minimum 12-inch gravel backfill zone with filter fabric to prevent clay from migrating into the drainage layer. The gravel provides a stable, non-expansive buffer between the wall and native soil.

Frost conditions: Base and footing design must reflect local frost conditions, drainage, soil, wall type, and applicable code. A single depth is not safe for every retaining wall; the project detail is selected for the actual site and wall system.

Steep terrain and drainage: Many properties sit on slopes of 15% to 30% grade or steeper. Surface water and subsurface water must be managed behind every wall. Our standard drainage system includes 4-inch perforated pipe at the base, wrapped in filter fabric, bedded in clean gravel, and daylighted to a safe discharge point.

Wildfire and defensible space: In areas like Black Forest and the foothills, retaining walls play a role in creating defensible space around homes. Non-combustible materials (block and stone, not timber) are preferred in high fire-risk zones.

Project Planning

Scope a Wall From Load, Drainage, and Grade

A retaining wall plan starts with the soil it holds, the water behind it, and the improvements located above and below it.

Document the Structural Inputs

We review exposed height, total retained height, slope, soil, surcharge loads, nearby structures, demolition, and equipment access before choosing a wall system.

Required permits or stamped plans are identified early, and CN Landscaping coordinates engineering when the site or wall height calls for it.

Build Water Control Into the Section

The installation detail specifies footing depth, compacted base, drain aggregate, filter fabric, outlet location, geogrid when required, and finished grading.

Block, natural stone, and timber are evaluated for structural demands, longevity, maintenance, wildfire exposure, and how the wall should look with the home.

Common Questions

Retaining Wall FAQs

Height, soil pressure, drainage, surcharge loads, demolition, access, finish preferences, and engineering needs are all confirmed before the wall proposal is finalized.

Permit and engineering requirements depend on total retained height, how the jurisdiction measures the wall, surcharge loads, slope, soil, drainage, and nearby structures. CN Landscaping reviews the site and coordinates with the Pikes Peak Regional Building Department and a licensed engineer when the project requires it.

Segmental concrete block walls are the most popular choice in Colorado Springs because they handle freeze-thaw cycles well, require no mortar joints that can crack, and install efficiently on sloped lots. Natural stone walls offer a premium aesthetic that blends with Colorado's terrain. Timber walls are the most practical but have a shorter lifespan of 15 to 20 years compared to 50+ years for block and stone. The best choice depends on wall height, structural requirements, and your design preferences.

Service life varies by material, soil, drainage, loading, exposure, maintenance, and installation. Long-lasting walls need site-appropriate base and footing design, drainage, reinforcement where specified, and construction that follows the selected wall system and any engineered plan.

Yes. Retaining walls are one of the most effective tools for managing water runoff and erosion on Colorado properties. By terracing a slope, you reduce the speed and volume of surface water flow. Combined with proper drainage behind the wall (gravel backfill, filter fabric, and perforated drain pipe), retaining walls redirect water away from structures and prevent erosion. Many Colorado Springs homeowners install retaining walls specifically to solve water management issues caused by the region's clay soils and steep lots.
