Hello everyone,
I have been tasked with calculating impervious surfaces in our municipality. What I need to calculate is the impervious area or the pervious area of a polygon (Parcel of land). The areas we have identified as impervious are sidewalks, driveways, patios and structures (houses/outbuildings), these are all polygon layers.

Is there a way to calculate the impervious surfaces of the property polygon by the polygons contained within it?
We currently have ArcGIS 9x and ArcGIS 10X but do not have the Spatial Analyst extension.

I am sure that I have done this before, but have been away from analysis for a while now.
Any help would be appreciated.

Are you still looking for help on this question, Dennis?

If you are, what attributes do the inner polygons (those within the parcels) contain?
