Evacuation Areas Public KML

Active evacuation boundaries for the state of Oregon - extracted from statewide hosted layer every 5 minutes and posted here as a KML. Statewide evacuation layer - showing current evacuations issued across Oregon. Data is entered by local/tribal/state GIS staff to indicate the status of evacuations across Oregon. Data updated as information is entered into the hosted feature service. If there are no records in this dataset, there are no evacuations currently in place. There are five integrations with this dataset, which are listed below: Clackamas County GIS's evacuation service - fed from the data featured on the Clackamas County Wildfire Evacuation Map, updates every 5 minutes. Deschutes County GIS's evacuation service - fed from the data featured on the Deschutes County Emergency Information Dashboard, updates every 5 minutes. Genasys platform - fed from the data featured on the Genasys software solution for zones not in a normal status, updates every 5 minutes. Data from the Perimeter solution is automatically synced with the ArcGIS Online hosted layer without any additional configuration necessary for the user. Once a polygon is created within that platform and saved, data syncs to the statewide service for visualization and display. Population and structure impact calculations are then conducted every 15 minutes. Data uploaded using the OEM evacuation service upload utility - updates every 15 minutes based on data submitted from an outside platform on a Survey123 form. Data calculations run every 15 minutes on this service and the calculations are derived based on the following: Structures within is based upon a selection query using the USA Structures Layer, featuring a count of structures in that boundary. Estimated addresses within is based off of the count of 911 GIS address points within the evacuation boundary. Estimated population is based off of the 2020 census household estimate of 2.53 persons per address (multiply estimated addresses by the household factor of 2.53).
