Here are the details from the City of Temecula:
The City of Temecula conducts a comprehensive weed abatement program each year as temperatures start to rise, and vegetation starts to dry out. This program is essential to the City’s proactive fire prevention measures, and programs like the weed abatement program can contribute to maintaining better insurance ratings Citywide.
Property owners throughout the City are required to maintain their property free of hazardous vegetation through the year, but the City conducts a specific proactive program each Spring. You can help maintain our community’s safety by keeping your property free and clear of hazardous vegetation by mowing or cutting hazardous vegetation.
