Step2:ReducingVulnerabilitiesThroughExistingProjectActionsWhichexistingprojectactionshelpaddresspotentialvulnerabilities?

Action:Managinggroundcovertoresultinamixtureofbareground,grasses,andforbs✔ Removes/Controlsinvasivegrasses

Action:Useirregularwidths,shapes,andpatternsinthefuelbreakdesign✔ Reducesthepotentialforincreasederosionbydecreasingareasofcompletevegetationremovaland

minimizingthedistancethatsoilcanmove

Action:Expandingwidthofthefuelbreak✔ Reduceswildfirerateofspreadbydecreasingavailablefuels

Action:Usingmechanicaltreatmentsforfuelremovalarounddwellingsandotheroccupiedbuildings✔ Reduceswildfirerateofspreadandpotentialseveritybydecreasingavailablefuels✔ DecreasestheriskofignitionsandpotentialwildfiredamageintheWUIbyreducingfuels

Step3:IntegratingNewProjectActionstoAddressRemainingVulnerabilitiesWhatadditionalactionscouldbeimplementedinthefuturetofurtherreduceidentifiedvulnerabilities?

Action:Plantnativeperennialgrasseswithinthefuelbreak ✔ Reducesinvasivegrassestablishmentbymaintainingdominanceofnativespecies,helpingdecrease flashyfirebehavior

✔ Increaseswaterinfiltration✔ Reduceserosionpotentialbyminimizingbaresoil

Action:Establishtriggerpointsforrecreationclosuresandrestrictions✔ Reducesthenumberofignitionsbyminimizingthenumberofhumansintheareaduringhigh-risktimes

Action:Includeenergycorridorplanningand/orestablishrestrictions✔ ReducesthenumberofignitionsandSantaAna(high-windevent)vulnerabilities

Action:Installemergencygreywatersystemsin‘safetyzones’✔ Providesnearbywaterforfightingfires
