Strength, Stability, and Design — Engineered for Scottsdale’s Desert Terrain
Retaining walls are more than just structural supports—they’re essential landscape features that protect Scottsdale properties from erosion, manage elevation, and enhance visual appeal.
In the unique desert environment of Scottsdale, Arizona, with its caliche soils, steep grades, and intense monsoon rains, retaining wall design requires specialized engineering and design expertise.
Why Retaining Walls Matter in Scottsdale
Scottsdale’s desert topography creates challenges that make retaining walls indispensable for both residential and commercial properties.
Managing Elevation Changes and Erosion
Hillside properties in areas like North Scottsdale and the McDowell Mountains often require retaining walls to stabilize slopes and create level, usable spaces. Properly engineered designs prevent erosion, especially during Arizona’s monsoon season.
Addressing Expansive Clay and Caliche Soils
Scottsdale soils—especially Casa Grande clays—expand when wet and shrink during dry periods, exerting powerful lateral forces on retaining walls. Our engineers design walls that withstand these stresses through precise load calculations, proper drainage integration, and foundation reinforcement.
Controlling Desert Water Flow
Monsoon rains can produce flash flooding and soil saturation. Schembri Engineers incorporates advanced drainage design—including weep holes, gravel backfill, and perforated piping—to prevent hydrostatic pressure buildup and maintain wall stability.
Common Retaining Wall Types for Scottsdale Properties
Every property has distinct requirements depending on slope, soil, and aesthetics. Here are the most effective wall types for Scottsdale’s environment:
1. Gravity Retaining Walls
- Use mass (stone or concrete block) to resist soil pressure
- Best for walls under 4 feet
- Blend naturally with desert landscapes
2. Cantilever Retaining Walls
- Reinforced concrete with an L-shaped design
- Ideal for taller walls or steep sites
- Provides strong, long-term structural support
3. Anchored Retaining Walls
- Utilize steel cables or anchors for maximum stability
- Excellent for tight spaces or challenging terrain
4. Gabion Walls
- Wire cages filled with stone for natural drainage and flexibility
- Ideal for erosion-prone or floodplain areas
5. Segmental Retaining Walls (SRWs)
- Interlocking concrete blocks
- Durable, flexible, and available in many colors and textures
- Great balance of form and function for Scottsdale homes
The Benefits of Professional Retaining Wall Engineering
Partnering with Schembri Engineers ensures your retaining wall does more than just hold back soil. Our engineered designs deliver:
✅ Erosion Control & Soil Stability
Protect your property from storm runoff, monsoon erosion, and shifting desert soils.
✅ Expanded Outdoor Living Space
Turn steep slopes into terraces, patios, and pool decks that enhance usability and curb appeal.
✅ Increased Property Value
Professionally designed retaining walls add long-term value through improved aesthetics, safety, and code compliance.
✅ Flood & Drainage Protection
Direct water away from structures and prevent costly water damage during Scottsdale’s seasonal downpours.
✅ Architectural Beauty
Natural stone, textured concrete, and tiered designs integrate beautifully with desert landscapes and modern architecture.
Engineering Considerations Unique to Scottsdale
Schembri Engineers evaluates all site factors that influence your wall’s design and performance, including:
- Soil composition and bearing capacity
- Lateral and surcharge loads
- Seasonal moisture variation
- Drainage system integration
- Foundation depth and reinforcement
- City of Scottsdale building code compliance
Walls over 4 feet, or those supporting structures and driveways, typically require engineered design and city permitting. Our team manages the process from analysis to approval.
Material Options for Desert Durability
Choosing the right material enhances both appearance and performance:
| Material | Advantages | Best Use |
|---|---|---|
| Concrete Masonry Units (CMU) | Durable, affordable, versatile | Residential & commercial walls |
| Natural Stone | Premium aesthetics, excellent durability | High-end residential & resort projects |
| Reinforced Concrete | Maximum strength & design flexibility | Tall or complex walls |
| Gabion Rock Cages | Natural drainage, rustic look | Erosion control, flood-prone areas |
| Treated Timber | Cost-effective for small walls | Short-term residential applications |
Cost Factors for Retaining Wall Projects
Project pricing depends on materials, height, and site conditions. Typical considerations include:
- Material selection: $15–$40 per sq. ft. (CMU to natural stone)
- Engineering design: Based on complexity and permit requirements
- Site preparation: Excavation through caliche and rock increases cost
- Drainage & backfill materials: Essential for longevity
- Labor: Typically 50–60% of total cost, depending on site access and wall design
