Sidewalk centerlines contain the centerline of sidewalks and crosswalks. The original data capture of the data in this layer was completed in 2014 using stereo models from the 2009 Virginia State imagery. Subsequent to that an update capture was completed in 2022 using stereo models from the 2017 Virginia State imagery. The most recent planimetric update was completed in 2024 using orthoimagery from the 2023 and 2022 Eagleview Orthophotos.

The centerlines of sidewalks along major and minor transportation features are captured as well as centerlines of connectors which are typically crosswalks or connections across driveways or parking lot entrances. Centerlines were captured rather than edges in order to be able to use the sidewalks as part of a network system. The sidewalks are attributed with a width value if it is necessary to buffer the centerlines to get an approximate area that is covered by the sidewalk for impervious surface calculations.
