5 Common Retaining Wall Mistakes in Palos Verdes & San Pedro (and How to Avoid Them)
A well-built retaining wall can transform a yard, prevent erosion, and protect your property for years to come. In hilly areas like Palos Verdes Estates, Rancho Palos Verdes, Rolling Hills Estates, or along the coastal bluffs in San Pedro, retaining walls are not just decorative—they’re essential. Unfortunately, many walls fail because of preventable mistakes. Here’s what to watch for:
1. Skipping Permits and Inspections
Hillside properties often require permits for retaining walls. Failing to get the necessary approvals can result in fines or even forced removal. Make sure your contractor handles all paperwork for your property and adheres to local building codes.
2. Ignoring Soil and Drainage Challenges
Sloped lots, canyon properties, and bluffside yards all have unique soil and drainage conditions. Neighborhoods like Marymount and Miraleste in Rancho Palos Verdes, with their steep canyons, and areas near Point Fermin and South Shores in San Pedro, are particularly prone to water accumulation behind walls, which can cause bowing or collapse. A professional will design your wall with the right drainage systems tailored to your lot’s specific terrain.
3. Choosing Materials That Don’t Fit the Site
Stone, concrete, brick, and timber each perform differently depending on height, slope, and local conditions. Selecting the right material ensures your wall stands the test of time and complements your property’s style.
4. Underestimating Wall Height and Load
Even walls that appear small may need to support significant weight from soil, plants, or vehicles. Steep hillsides, like those in Rolling Hills Estates or along Palos Verdes Drive, require careful engineering to ensure the wall safely handles the load.
5. Not Accounting for Local Landscape Features
Each lot has its quirks—coastal winds, hillside erosion, or uneven slopes can all affect wall stability. Walls built without considering these factors often face costly problems down the road. Experienced contractors take the local terrain into account to ensure a durable, safe result.
