When Your Property is Moving (And Not in a Good Way)

Cracks appearing in existing retaining walls or getting wider

Wall leaning or bulging outward from soil pressure

Drainage problems with water pooling or erosion behind walls

Soil sliding down slopes after heavy rains

Property damage from slope failure affecting foundations, driveways, or structures

The Hidden Dangers of Failing Retaining Walls:

○ Property damage from soil movement affecting your home's foundation

○ Safety hazards from potential wall collapse or slope failure

○ Liability exposure if wall failure damages neighbor's property

○ Insurance complications from "earth movement" exclusions

○ Property value loss from visible slope stability problems

○ Expensive emergency repairs when problems become critical

Orange County's Unique Challenges:

○ Expansive soils that move with moisture changes

○ Seismic activity requiring earthquake-resistant wall design

○ Heavy winter rains creating drainage and erosion problems

○ Steep topography in hillside communities requiring specialized solutions

○ HOA requirements for aesthetics and engineering standards

How much does a retaining wall cost in Orange County?

Retaining wall costs vary widely by type, height, and site conditions. Engineering typically costs $2,000-8,000, with construction costs ranging from $15-100+ per square foot depending on wall type and complexity. We provide detailed cost estimates after site evaluation.

Do I need a permit for my retaining wall?

Most retaining walls over 4 feet high require building permits in Orange County jurisdictions. Walls supporting structures or surcharges may require permits at lower heights. We handle all permit requirements as part of our engineering service.

How long do retaining walls last?

Properly engineered and constructed retaining walls should last 50+ years with minimal maintenance. Poor drainage and inadequate engineering are the primary causes of premature failure.

Can you fix my existing failing retaining wall?

Often yes. We evaluate existing walls to determine repair feasibility versus replacement needs. Many failing walls can be stabilized and repaired at significant cost savings compared to complete replacement.

What's the difference between a landscape contractor and structural engineer for retaining walls?

Landscape contractors install walls, but structural engineers design them for safety and code compliance. For walls over 4 feet or critical applications, California law requires structural engineering.

How do you handle drainage behind retaining walls?

Proper drainage is critical for retaining wall success. We design integrated drainage systems including weep holes, drainage pipe, filter fabric, and gravel backfill to prevent hydrostatic pressure buildup.

Jonathon and his team were top professionals when I hired them to take over an project that was going sideways with another firm. They were very responsive, helped me salvage what I could from the previous firm, and provided the expertise and knowledge needed to finish the job quickly and efficiently. Jonathon went above and beyond to make sure I understood the process and answered all of my questions patiently. I will hire them again for my next structural engineering project and strongly recommend them if you need work done right the first time.

Amazing communication from this amazing team. Absolute value for the all inclusive services you get from a professional and prompt team. I used architecture and engineering services for a major home addition and remodel. Additionally, Jonathon and his network was able to handle every issue from the city including great referrals for soil report and grading plan engineer. Don’t bother wasting your time getting more quotes, this is the firm to use.
