When would a large-scale evacuation occur? Fortunately not very often. Portland does not face the types of hazards, such as hurricanes or tsunamis, that typically trigger evacuations. Our most dangerous threats would happen without warning.
Some neighborhoods face unique challenges. PBEM has identified five areas within the city that may face unique challenges to successfully evacuate, such as topography, lack of transportation options, population density and building types:
Current draft of the City of Portland's Evacuation Plan.
Memorandum with the transportation analysis results of an orderly evacuation scenario in the Portland metro area.
Draft evacuation plan specific to the Downtown Central Business District.
Draft evacuation plan specific to Forest Park.
Draft evacuation plan specific to Hayden Island.
Draft evacuation plan specific to the Linnton Neighborhood.
Draft evacuation plan specific to the Multnomah County Drainage District (MCDD).
