The Norco Fire Department conducts field inspections twice a year on vacant lots within city limits for weeds/tumbleweeds. Abatement for tumbleweeds is conducted every fall and abatement for weeds is conducted every spring.

Abatement of weeds on a vacant lot is the responsibility of the property owner. Property owners whose lots are listed on the Fire Department's master vacant parcel list receive notification to abate hazardous weeds and vegetation.

The property owners are given deadline abatement dates. Due to the significant threat to life, property and the environment, a non-compliance fine of $250 is assessed when the property owner fails to abate their lot after the established deadline.  In addition, any vacant lots that are not abated voluntarily and require abatement by the City Contractor will also be assessed the contractor’s cost plus the City’s administrative abatement fee, which is 100% of the contractor’s cost.

Parcels less than 10 acres shall be completely cleared of hazardous vegetation. Parcels 10 acres or greater shall have a minimum 30-foot fire break around the perimeter, and shall be divided by a minimum of a 30-foot fire break into areas not exceeding 5 acres each.
