With respect to calculating the "Square footage of all parking areas" . . . is that square footage calculation to include the paved route to access to spaces such as in a  parking lot situation?  Is the square footage to include the roadway as well if parallel parking spaces provided adjacent to a roadway? 

OR - is this square footage to simply be calculated as the actual square footage of the parking spaces themselves (for example 9'-0" x 18'-0" for each parking space) - not counting the access?

Thanks!
