Our Geographical Makeup

Hillside homes throughout Los Angeles County are a valuable possession for many who live in Southern California. Beautiful designs and attractive scenery make hillside properties highly desirable.

However, there are inherent concerns with living in these kinds of homes. The main fear being the threat of water. From the Santa Monica Mountains, to the San Gabriel Mountains, intersecting in between with the mountain ranges of Hollywood Hills and Beverly Hills, passing along to Newhall and the Santa Susana Mountains, it happens often that rainfall will damage the homes across these areas, and flood into the valley, enclosed by all these mountain ranges. The cities right along the base of hills are the ones most in danger, such as in Encino, CA.

Fear vs. Comfort

In Los Angeles, there are two ways to describe mountain ranges in reference to lifestyle: that of fear and that of comfort. Comfort zones tend to be on the higher peaks and the feared ones in the lower altitudes.

Either way, it is not very natural that homes are built along the base of mountains. Conditions are dangerous. Water problems, fire damage, and earthquakes, in particular, can leave your home at risk of ruin.

It is natural catastrophes that add distinct contrast to the perfect wonder of eye-catching hillside homes, rainfall being the most dangerous. Torrential or long-lasting rainfall accentuates the need for solutions to common drainage problems throughout Los Angeles County.

Beautiful homes on a hill


Hillside homeowners know the kind of gem they possess. And like most precious gems, hillside homes need proper protection to preserve their value. They also need to express their purpose: to provide you and your family with safety and peace of mind.

Erosion and Runoff

Hillside Drainage can help

Hillsides are not always stable and reliable.

Erosion and runoff are two common reasons homes experience slide failure and shifting. If homeowners wait too long, repairing the concrete foundation of their home may become very costly.

Weinstein Retrofitting Systems recommends that homeowners who live along the Santa Monica and San Gabriel Mountain Ranges contact us today to schedule an inspection with one of our hillside drainage system specialists.

If you own a hillside property, protecting it from erosion and runoff is the best preventative measure you can take to keep your home safe.

Erosion and runoff are caused by torrential rainfall, fire damage, and most obviously, the flow of gravity.

Questions you should ask yourself include:

• Is there a properly working hillside drainage system in place?
• Is the hillside stable or will shifting occur when the ground becomes saturated?
• Will the landscaping and ground cover protect against erosion?
• Does the grade sloping of your property best utilize gravity’s advantage?

The specific condition of your hillside home will determine the kind of solution you may need to implement in order to keep your home safe from water damage during the rainy season.

Slope stabilization begins with proper hillside drainage

If left untreated, hillside drainage problems can leave your home in a serious state of danger. Slope stabilization begins with the proper hillside drainage system installed at your home. With poor drainage management, your hillside property can become easily susceptible to landslide failure. Add earthquakes to the equation, and damage can be detrimental and even fatal.

Hillside Drainage Problems & Solutions

Retaining Walls

Hillside Drainage

A retaining wall can help keep your homes foundation stable.

Hillside retaining walls are at a significant risk of becoming damaged when water spills down the slope and up against the wall. The water will weaken the footing, and the wall will eventually begin to crack or tilt. Failing retaining walls can bring unwanted landslides into your yard and may turn your yard into a heaping mess of debris. The installation of French drains along the retaining wall will greatly reduce these risks and mitigate the damages of the runoff water.

Terraced Hillsides

There are many options available to help you stabilize your slope.

Hillsides with steep pitches can bring water flow at a rapid speed, which also brings more soil with it. To prevent this, laying down erosion blankets or gabion blankets, which are rocks hand-placed inside of galvanized mesh wiring baskets, will slow the water down and add a natural way for water to travel. These blankets act as “speed bumps” for the control of the water flowing down the hillside. They blend well with the environment, they’re long-lasting, and depending on the layout of your landscaping, they can serve multiple functions.

Roof Runoff

Hillside Drainage can prevent water from pooling around your home and seeping in to your foundation.

Roof runoff water can pool in undesired places around your home and encourage soil erosion. By installing gutters and downspouts, homeowners can control the flow of roof runoff water, allowing it to hit concrete driveways instead of sensitive soil.

Grading for Drainage

Hillside Drainage

Directing water with trenches can help proper drainage.

By building or digging troughs or trenches, or swales around the perimeter of your hillside home, you can control the direction of how water travels. Additionally, you can redirect the path of water to flow down your driveway and to a storm drain or other catch basin, or water outlet. Concrete curbs may be erected in and around your home to also help direct the flow of water.

We use high-performance and long-lasting Schedule 35 PVC piping to design and install the best drainage system to divert rain water away from your home and getting water to the street via gravity. Our company specializes in this type of service and we have been in business for over 35 years. Our hillside drainage systems are backed by our 25-Year Warranty for your peace of mind.
