| Abstract | Areas of elevated risk for wild land fires. Vegetation, Slope, and the ODF Fire Weather Hazard ratingwere the main factors used in the wildlands hazard zone analysis done in 2002using ArcGIS software. Developed Land designations were further used to refinethe product. Golf Courses and Industrial Zoned Lands were excluded. The finalanalysis was mapped to taxlot parcels where 50% or more of the taxlot andadjacent taxlots fell into the boundaries of the Wildland Hazard Zone.Additional custom edits were made based on visual inspections by Portland Fire& Rescue. | |||||
| Purpose | For generalized mapping and analysis of areas exposed to wild land fire hazard. ORS 93.270(4) enacted by the 1993 legislature and changes toOregon's Building Code encourage local governments to voluntarily designatethose portions of their jurisdictions subject to catastrophic fire as WildfireHazard Zones. The purpose of these zonesis to define those areas where buildings need to be made more survivable fromfires spreading through adjacent wildlands. This analysis and map are designed to address the statuteand identify areas which are Wildfire Hazard Zones within the City orPortland. | |||||
