Berkeley FAQ
Is French broom really that dangerous?
Yes. Broom is classified as a high-volatility ignition source by CAL FIRE. Berkeley aggressively pushes eradication within the 100-foot defensible space zone, and broom clearance is a frequent abatement trigger.
Can I use Roundup on my weeds?
Glyphosate use on private property is legal but discouraged. Berkeley prohibits its use on city land and recommends manual removal, flame weeding (outside fire season only), or vinegar-based products.
Hayward FAQ
Can I opt out if I promise to mow?
You can self-abate by the deadline; otherwise the city will include your parcel in the contract.
How do I dispute charges?
Attend the Council confirmation hearing before the abatement happens to object and present evidence of compliance.
