The Issue
Why are residents concerned?
Ladera Ranch is known for its beautiful parks, trails, greenbelts, and neighborhoods. These shared spaces are part of what makes our community unique and why so many families choose to call Ladera Ranch home.
Like any master planned community, maintaining these landscapes requires ongoing care. Weed control, irrigation, fertilization, pruning, and pest management all play a role in preserving the appearance of our parks and common areas.
In recent years, many residents have begun asking an important question:
Can we continue to preserve the beauty of Ladera Ranch while reducing our reliance on pesticides?
Concerns surrounding pesticide use, reports of several pediatric Ewing sarcoma cases within our community, and growing awareness of healthier landscape management practices have prompted many residents to seek answers and explore alternatives.
We are not claiming that pesticides caused any specific illness. However, we believe these concerns deserve transparency, thoughtful discussion, and a careful evaluation of how our shared landscapes are managed.
Understanding Pesticides
Pesticides are products used to control unwanted weeds, insects, fungi, rodents, and other organisms.
They include:
• Herbicides to control weeds
• Insecticides to control insects
• Fungicides to control plant diseases
• Rodenticides to control rodents
These products are widely used in agriculture, public parks, schools, golf courses, commercial properties, and residential landscapes.
Because pesticides are designed to affect living organisms, many experts recommend using them thoughtfully and only when they are truly necessary.
Health Considerations
Scientific research has examined pesticide exposure and its potential relationship to a variety of health outcomes, including certain cancers, neurological disorders, reproductive effects, and impacts on children's development.
Risk depends on many factors, including:
• The specific product
• Frequency of exposure
• Duration of exposure
• Method of application
• Individual susceptibility
Not every pesticide presents the same level of risk, and not every exposure results in harm. However, reducing unnecessary exposure is widely recognized as a practical approach, particularly for children, pregnant women, pets, and people with repeated exposure.
Environmental Considerations
Landscape management affects more than the plants we see.
Depending on the product and how it is used, pesticides may also affect:
• Pollinators
• Beneficial insects
• Birds
• Soil microorganisms
• Aquatic ecosystems
• Overall biodiversity
Healthy landscapes depend on healthy ecosystems. When those systems become less resilient, landscapes often require more ongoing maintenance and greater reliance on chemical interventions.
Legal Does Not Mean Risk Free
Pesticides used in California undergo review by state and federal regulatory agencies before they can be registered for use.
Registration means a product has been approved for use under specific conditions and according to its label. It does not mean that the product is completely risk free.
Around the world, regulatory agencies sometimes reach different conclusions about certain pesticides. Some products approved in one country have been restricted or prohibited in others as scientific understanding evolves and different approaches are taken to balancing benefits and risks.
As research continues, pesticide regulations continue to evolve.
Why Ladera Ranch Faces This Challenge
Ladera Ranch was thoughtfully designed to create one of Southern California's most beautiful communities. Tree lined streets, lush parks, colorful landscaping, and well maintained greenbelts remain an important part of its identity.
When the community was planned more than two decades ago, landscape design understandably prioritized appearance and creating a welcoming environment. At the time, there was less emphasis on today's understanding of climate appropriate landscaping, soil health, biodiversity, water conservation, and prevention first landscape management.
As a result, some landscapes throughout our community require:
• More irrigation
• More fertilizer
• More pruning
• More weed control
• More pest management
• More ongoing maintenance
This does not mean these landscapes are undesirable, nor does it mean they should all be replaced.
It simply means many of them require greater inputs than landscapes designed around Southern California's climate and modern landscape management practices.
Today, communities across California are exploring ways to preserve beautiful landscapes while reducing water use, improving soil health, increasing biodiversity, and reducing unnecessary reliance on pesticides.
Ladera Ranch has the opportunity to do the same.
Progress has begun
We appreciate that LARMAC has already taken steps toward healthier landscape management.
In 2021, LARMAC announced efforts to explore Integrated Pest Management (IPM) and organic landscape practices in select areas of the community. These pilot efforts demonstrate a willingness to explore new approaches and recognize the importance of reducing unnecessary pesticide use.
We believe these efforts represent an encouraging first step.
However, lasting change requires more than isolated pilot projects. To meaningfully reduce reliance on pesticides while preserving the beauty of Ladera Ranch, prevention first landscape management should become a long-term commitment across all HOA maintained landscapes.
A Different Question
When discussing pesticides, the conversation often becomes focused on which product should be used.
We believe a more important question comes first.
Why does the landscape require pesticides in the first place?
By asking that question, the conversation expands beyond individual products and toward the overall health of our landscapes.
Healthy soils.
Resilient plants.
Thoughtful plant selection.
Proper irrigation.
Integrated Pest Management.
These are the building blocks of landscapes that naturally require fewer chemical interventions while preserving the beauty that makes Ladera Ranch special.
A Better way forward
This conversation has grown following concerns about pesticide use in our common areas, reports of several pediatric Ewing sarcoma cases within Ladera Ranch, and increasing public interest in healthier approaches to landscape management.
We recognize the profound impact these diagnoses have had on the affected families and the concern they have raised throughout our community.
While we are not claiming that pesticides caused any specific illness, we believe these concerns deserve thoughtful discussion, greater transparency, and a careful evaluation of how our shared landscapes are managed.
We also recognize that LARMAC has already taken positive steps by exploring Integrated Pest Management (IPM) and other sustainable landscape practices in select areas of the community. We appreciate these efforts and believe they represent meaningful progress.
However, meaningful change requires more than individual projects or limited pilot programs.
Our hope is to see these efforts expanded into a long-term, community-wide commitment that is consistently applied throughout all HOA maintained landscapes and continues beyond changing priorities, management companies, or Board leadership.
Our goal is not simply to reduce pesticide use or replace one product with another.
Our goal is to encourage a Prevention First approach to landscape management that keeps Ladera Ranch beautiful while reducing the need for pesticides whenever possible.
We believe the conversation should focus not only on the products being applied, but on the overall system used to care for our landscapes. By improving soil health, selecting plants better suited to Southern California, strengthening biodiversity, and consistently applying Integrated Pest Management principles, we can create healthier, more resilient landscapes that naturally require fewer chemical interventions.
The goal is not to change the character of Ladera Ranch.
The goal is to preserve the charm we all love while embracing modern, science-based landscape management practices that protect our environment, strengthen our community, and create healthier landscapes for generations to come.
