Fremont FAQ

Does the city mow vacant lots for me?

No. Owners are responsible. If you fail to comply, the city will hire a contractor to mow at your cost plus administrative fees, typically 500 to 2,500 dollars per parcel depending on size and access.

Are poison hemlock and yellow star thistle priority weeds?

Yes. These California Invasive Plant Council listed species are flagged for abatement even when green. Property owners should use gloves, long sleeves, and dispose of plant material in the green waste cart, not compost piles.

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.
