The new ordinance can be divided into three categories: Category 1 *Defensible Space The area within 100 feet of a structure must be maintained to provide a “Defensible Space” where vegetation is less flammable and not excessive in volume. *”Defensible Space” allows firefighters to work around the structure while protecting it from fire.
REVISED BRUSH CLEARANCE ORDINANCE(CONTINUED) Category 2 Fuel Modification Zone • Reduce the fuel load from 100 to 200 feet from structures • Prune branches from lower third of native plants • If plant/ tree is over 18 feet prune up 6 feet from ground • Remove all dead vegetation from plants and you may machine process ( chip and spread ) no deeper than 3 inches, 30 feet from structures nor 6 inches deep beyond
