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. The hierarchy for this logic is as follows:<\/SPAN><\/P>

- Medians (Maintenance Areas with FACILITYTYPE = 'Median' AND SURFTYPE = 'Hard')<\/SPAN><\/P>

- Buildings<\/SPAN><\/P>

- Roads<\/SPAN><\/P>

- Parking Lots (SURFACETYPE = 'Impervious')<\/SPAN><\/P>

- Driveway<\/SPAN><\/P>

- Sidewalk<\/SPAN><\/P>
