The Ladera Ranch Maintenance Corporation (LARMAC) main homeowner association board is expected to consider potential changes to its landscape management practices at its regularly scheduled resident meeting on September 9. The meeting, to be held in the Covenant Hills Village Clubhouse, will include the presentation of recommendations from the Ad Hoc Landscape Pest Management Advisory Committee.
These discussions follow significant community awareness raised by Ladera Ranch residents regarding child cancer cases in the area, leading to calls for investigations into potential environmental factors, including local weed control, soil, and watering practices. Jaclyn French, a Ladera Ranch-based attorney working with residents and LARMAC, stated that resident concerns made it clear that "the community wants a thoughtful transition away from routine synthetic herbicide use."
LARMAC has already taken interim steps, including extending a pause on spraying until November and agreeing to remove certain pesticides from use. The advisory committee, which held its initial meeting on July 23, expressed a shared long-term vision of reducing reliance on synthetic pesticides through a thoughtful, phased transition toward organic and cultural landscape maintenance practices where practical. French affirmed that LARMAC "is showing that it is listening and responding to resident concerns." At least one sub-association within Ladera Ranch has already voted to permanently cease spraying.
The issue has also drawn attention from various other entities. State legislators are considering resolutions on pesticide use, and French's group contributed public comments to the California Legislature’s joint oversight hearing on state pesticide regulation. Local school district officials in Ladera Ranch have also agreed to extend a pause on weed-control spraying until a new Integrated Pest Management plan, which moves away from synthetic pesticides, is implemented. The LARMAC advisory committee is collaborating with the Washington, D.C.-based nonprofit Beyond Pesticides to support an application for a $1 million grant from California’s Sustainable Pest Management Grant Program, aimed at developing a pilot program for shifting away from toxic chemicals.
Separately, the California Department of Public Health recently informed French that the agency has launched a dedicated public webpage for the Ladera Ranch community cancer concern assessment. Orange County’s Agricultural Commissioner, Jose Arriaga, is continuing his agency’s investigation into local toxin use and public notification practices. Residents, in collaboration with a Cal State Fullerton research team, are also developing a water and soil testing plan for the community.
Residents have also directed inquiries to the Rancho Santa Margarita Water District (RSMWD) regarding recycled water conditions and public records requests. RSMWD Director of Government and Public Affairs Alyson Piguee stated that the agency addressed one public records request in a timely manner but acknowledged administrative oversights that delayed responses to another, expressing regret for the mistake. Piguee added that RSMWD "conducts more than 30,000 tests annually, confirming that drinking water meets or surpasses all state and federal regulations," and has created a webpage to address resident questions.
Looking ahead, French emphasized that significant work remains, with a focus on establishing a strong, lasting Organic Land Management policy for Ladera.
