Description: The Guardrail layer includes over 1,800 line features that are adjacent to county-maintained roads. The IMD Pavement Management Program is responsible for populating attributes for these features, including the assignment of the SegID identifying the adjacent pavement segment. This layer also includes over 2,800 additional features that were digitized by Sanborn from aerial photography. These features are not adjacent to county-maintained roads and do not have inventory dates or a complete set of attributes, but are included to provide context and completeness. This layer also identifies 350 different runs of guardrail that are thought to be damaged based on comments and photos collected by the Survey team when they collected the initial inventory between Jan - Dec, 2020. Damage-related information will be updated as repairs are made. Information about future damage to guardrail will be maintained in the VueWorks work order system, and not recorded in this layer.

Description: The line geometry of this feature class is derived from the Street Centerline dissolved on Road Number (AAROADNO), and is refreshed from its source nightly. Road attributes are sourced via a "live" connection to the roadinv_prod.roadinv table in the Bureau of Highway's Road Inventory database. Updates made to the Road Inventory database are immediately reflected in the attributes of this layer.

Description: The Curb Ramp Priority Zones are 1/4-mile service areas generated from the service networks around points of interest, such as government buildings, transit stops, schools, hospitals, parks, and shopping centers. POIs were divided into two categories depending how close they were to the network. POIs over 250' from the network were assumed to be far away or have a driveway and were forced to connect a service line to a main line road (excluding local, tbd, and blank). POIs less than 250' from the network were buffered 250' to create entry points into the network. The service area was then drawn, without FCC constraints, under the assumption a pedestrian and could enter the network from multiple places. Service lines were combined and buffered an 75' feet to account for ROW and sidewalk along the road. These networked priorities were erased from the school walking zones to allow for a 4th category "WZ."The zones are used to assign a priority level -- 1, 2, 3, WZ, or "Reg" -- to every curb ramp in the county inventory. The priority levels are used as inputs to planning for the curb ramp (re)construction needed for the county to reach full ADA compliance.
