Castro Valley FAQ

How do I remove my parcel from the program?

After multiple years of self-compliance and passing inspections, you may petition removal; contact the Weed Abatement Coordinator at Alameda County Fire.

Can I do the work myself?

Yes, self-abatement is expected and encouraged; just complete the work before the inspection deadline to avoid county abatement charges.

Livermore FAQ

Is yellow star thistle a regulated weed in Livermore?

Yes. It's a state-listed noxious weed and must be controlled, especially on fire-prone parcels subject to LPFD abatement.

Can I use herbicide instead of mowing?

Yes, but dead vegetation must be removed or disked after treatment — standing dry fuels are still a fire hazard under PRC §4291.
