HS 2 Hardscape: all nonbuilding manmade hard surface on
the lot such as parking areas, walks, drives, and patios.
Hardpacked areas such as gravel parking areas are
included. Pools, fountains, and similar water-covered
areas are included if they are on impervious surfaces
which can be exposed when the water is emptied

proposed design (including the additions if applicable).
This includes all finished interior ceilings, flooring
surfaces, doors, windows, casework, walls (count
both sides), and visible casework surfaces. It is easy
to understand if one pictures the finished interior
surfaces that can be seen in all the rooms, but with
doors and windows only counting once
