All polygonal areas in this dataset are derived from LIFECYCLE = 'Active' assets in the feature classes inside the Public Works planimetric areas dataset. The layers that make up this derived feature class also participate in a pseudo-topology. For example, if a Building polygon overlaps a Driveway polygon, the script will \"over-rule\" the bit of intersecting Driveway and call it a Building.
