**Understanding Hillside Retaining Walls in Los Angeles**

# Why Are Hillside Retaining Walls Necessary?

In a city like Los Angeles, with its diverse topography and occasional heavy rains, hillside retaining walls serve several critical purposes:

1. **Soil Erosion Prevention**: They prevent soil from sliding down slopes.

2. **Water Drainage Control**: They help manage water runoff during storms.

3. **Aesthetic Appeal**: A well-designed wall can enhance the beauty of your landscape.

# Gravity Walls

Gravity walls rely on their weight to resist the pressure of the soil behind them. Made from heavy materials such as concrete or stone, they are simple yet effective structures.

# Reinforced Soil Walls

This type uses layers of geogrid materials combined with soil to create a stable structure without requiring massive amounts of concrete or stone.
