Description: Disaster Routes description courtesy of LA County DPW Disaster Routes website (http://dpw.lacounty.gov/dsg/disasterroutes/):Disaster Routes play a primary role in disaster response and recovery. During a disaster and immediately following, Disaster Routes are used to transport emergency personnel, equipment, and supplies into an affected area in order to save lives, protect property, and minimize impact to the environment. During a disaster, Disaster Routes have priority for clearing, repairing and restoration over other roads.It should be noted that Disaster Routes are not evacuation routes. Although an emergency may warrant that a road be used as both a Disaster Route and an evacuation route, they are considered to be different. An evacuation route is used to move an affected population out of an impacted area.According to the CAMS_ROADS metadata (http://egis3.lacounty.gov/dataportal/2014/06/16/2011-la-county-street-centerline-street-address-file/), this file should NOT be used for 1) routing and network analysis, and 2) jurisdiction and pavement management.Some on and off ramps are included for road continuity purposes. In addition, freeway transitions tend to be labeled as ramps in CAMS_ROADS.
