OC halts use of chemicals that critics say poison the county’s creeks and coast

Orange County will stop spraying local flood control channels with toxic chemicals — an environmental issue that has morphed in recent months into a major theme in the June 2 primary race to represent South O.C. on the Board of Supervisors.

In an emailed announcement, Supervisor Katrina Foley, who represents District 5, wrote that “following months of community outcry,” O.C. Public Works would halt spraying and “instead observe the growth patterns of invasive species to evaluate the safest and most effective procedures for removal.”

The backstory

The environmental activists who make up the three-person Creek Team OC began raising the alarm earlier this year about the county’s practice of spraying toxic chemicals to keep vegetation down in local waterways and flood control channels, which flow out to the ocean. Brent Linas, the group’s founder, had become concerned about the issue while noticing what he characterized as “dead” ecosystems during his runs along San Juan Creek, which empties into Doheny State Beach.

The political context

The herbicide spraying had become a major issue in the race to represent District 5 on the Orange County Board of Supervisors. Katrina Foley, a Democrat, is running for reelection against state Assemblymember Diane Dixon, a Republican. The conservative Lincoln Club, through its PAC, has spent around $200,000 thus far to try to influence the race. The PAC has latched onto the herbicide issue to attack Foley in ads and mailers.

The Lincoln Media Foundation, which shares an address and officers with the Lincoln Club, has simultaneously published content critical of Foley’s handling of the herbicide issue through the affiliated publication, California Courier.

Linas of Creek Team called Foley’s announcement about the countywide pause on herbicide spraying “a huge, huge victory for us.” Linas, who described himself to LAist as a lifelong Democrat, said his group ultimately used the political jockeying over the issue to their advantage. “ We took this firehose of money that exists and we redirected some of it towards what we saw as an urgent issue,” he said.

What’s next?

Orange County Public Works could still use herbicides in conjunction with maintenance work if they identify an “immediate need of vegetation management,” according to the announcement. But the county would give the public seven days' notice in advance of any such use. A pilot project along San Juan and Trabuco creeks is underway to evaluate the viability of replacing chemical spraying with manual and mechanical weed removal.

How to watchdog your local government

One of the best things you can do to hold officials accountable is pay attention. Your city council, board of supervisors, school board and more all hold public meetings that anybody can attend. These are times you can talk to your elected officials directly and hear about the policies they’re voting on that affect your community.
