One or more persons related by blood, adoption or marriage, living and cooking together as a single housekeeping unit, exclusive of household servants. A number of persons, but not exceeding two, living and cooking together as a single housekeeping unit though not related by blood, adoption or marriage shall be deemed to constitute a "family."

The ratio begins at the ground level of a property lot line and rises over the zoning lot at a maximum ratio of vertical distance as set forth in this chapter. The height/setback ratio as established in the zoning regulations shall be measured using either the front, side or rear property line as may be appropriate for the particular ratio being applied.

Footprint of all buildings, structures, and covered surfaces, including but not limited to dwellings, garages, cabanas, tennis courts, sports courts, pools, spas, driveways, pavement, patios, paved areas, pavers, bricks, gravel (50% of gravel area counts as impervious surface), walkways, walls, artificial turf, fences, piers, and equipment pads.
