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><\/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>- ImperviousMisc<\/SPAN><\/P><\/DIV>",
