RoadLog Mobility

This layer is a comprehensive depiction of roads within Island County that have an assigned MOBILITY Road Log Number. Road log numbers are used by the County for storing and managing most roads engineering data. Most importantly, the road log numbers correlate to the CRAB's MOBILITY database. By default Roads_Mobility consists primarily of roads owned by Island County. The centerlines of this layer were copied from Roads_Address. Roads_Address was photogrammetrically generated from 2007 aerial photos of the county. All attributes within Roads_Mobility were conflated from pre-existing centerline layers. Roads_Mobility is a spatial subset of Roads_Address. Roads_Mobility plays a secondary role in a topology (Roads_and_Tranportation_Topology). Topology rules require all centerlines in Roads_Mobility are spatially coincident with features in Roads_Address. Spatial editing of Roads_Mobility should occur within Roads_Address with coincident edits applied to Roads_Mobility polylines.
