Sandblasting Lawsuit


Toxic Sandblasting Affecting Westridge/Stevenson Ranch Residents

We have filed a complaint in the Los Angeles Superior Court on Monday, November 23, 2020, against the parties who are responsible for the violation of the “quiet use and enjoyment” of your property, for “trespass,” and who may, in fact, be causing you physical injury.

The residents of Westridge/Stevenson Ranch are being wrongfully endangered by the toxic particles being blasted into the air by the sandblasting taking place as part of the Fivepoint Valencia project.

View video of damage in your neighborhood and learn more about this case:

We have been provided with substantial documentation, voice recordings, audio recordings, video recordings, still photographs, and drone footage taken by residents. It shows the toxic cloud and rust particles floating over the Stevenson Ranch and Westridge communities. Our law firm saw massive amounts of debris from the sandblasting despite the fact that we were hired after the sandblasting had stopped.

  • Since first learning about the situation, we have performed test sampling of 13 homes in the community and have found the toxic particles in all 13 homes.
  • The particles are extremely light and can float in the air for long periods, traveling many miles by wind and then settling on the ground or in the water.
  • Neighbors found debris in their backyards, on their decks, vehicles, and on their children’s play-sets.
  • Based upon the location of our positive test samples, it appears that all homes in these communities have been affected.
  • The laws of the State of California protect homeowners and tenants that reside in homes that are subjected to what is occurring in your backyard.
  • You have a right to the “quiet use and enjoyment” of your home and property. You are entitled to be free from “trespass.”
  • They have created a nuisance, making it impossible for people to enjoy their backyards.
  • In addition to the property damages, many of our clients recall having unexplained health-related symptoms over the last four months to varying degrees, including but not limited to the following: Nosebleeds, Headaches, Sinus issues, Lung issues, and Throat issues.

Exposure to such particles can cause health issues that affect both your lungs and heart. Numerous scientific studies have already shown that particle pollution exposure has been linked to several conditions, including:

  • Premature Death
  • Reduced lung function
  • Aggravated asthma
  • Heightened respiratory symptoms, such as irritation of the airways, coughing, and trouble breathing

These dangerous particles can also cause property damage to your cars and homes.

Excerpt from Westridge Homeowner’s Association:

“It has recently come to the Association’s attention that some homeowners may have suffered varying degrees of property damage and/or physical effects from the construction of the additional water tower adjacent to Westridge Parkway.”

“There are a number of impacted homeowners and neighbors who have been able to connect with each other on this issue to have a collective voice in communications with the entities involved in the construction.”

Quote from a Stevenson Ranch resident:

“We have been exposed to and breathing in what they’ve been sandblasting into our neighborhood. Our property has been damaged by the sandblasting. We have not been able to be in our own backyards because of the air quality and the noise caused by the sandblasting. There was a failure in oversight by just about every party involved and negligent actions in the sandblasting. I’m hoping there’s someone who can help us with this.” -Santa Clarita Homeowner

What is Sandblasting?

Sandblasting is a surface treatment process that removes coating, corrosion, or contamination from a hard surface using pressurized air or water. This method is often used in construction projects to:

  • Smooth rough surfaces
  • Make smooth surfaces rough
  • Remove contaminants or material such as paint, rust, or residue from surfaces
  • Clean or prep a surface
  • Finish surfaces

How is Sandblasting Toxic?

According to the Centers for Disease Control and Prevention, abrasive blasting creates sand particles that may contain harmful chemicals like crystalline silica or iron oxide. Crystalline silica has been linked to serious or fatal respiratory disease. If inhaled, fibroid growths and scarring can form in the lungs. If the growths become too large, it can become difficult to breathe and may result in death.

If the particles contain iron oxide, exposure to fumes can result in a number of conditions including metal fume fever. This flu-like illness has various symptoms including metallic taste, fever and chills, aches, chest tightness, and cough. With repeated exposure, the metal dust can cause chronic lung conditions. Prolonged exposure to metal dust like steel, iron, and cobalt can cause health conditions such as siderosis and black lung.

How Do I Know If I’ve Been Impacted?

Since June 2020, sandblasting from the construction of the water tower has negatively impacted the lives of many of the Stevenson Ranch residents. Homeowners have had to endure extremely loud sandblasting noise, which has hurt the quality of life for many people in the area.

Recently, homeowners have noticed sand in their pools and a heavy layer of dust accumulating on their cars and in their yards. Other neighbors have claimed that the dust created from the sandblasting project is so abrasive that it damaged their air conditioning units, scratched the paint on their cars, and caused their windows to become pitted with tiny pot marks.

Beyond the property damage, perhaps the most concerning issues reported are related to the physical health of the residents. Locals are also claiming the dust particles are so thick that they can “taste the grit in the air” and are now having instances of migraines, sleep issues, nose bleeds, sinus inflammation, and vomiting.

Despite multiple complaints to the management team overseeing the construction of the water tower, there has been no action to halt the project to-date.
