Special land uses in residential areas get at most 12 square feet of building signage.
Ground signs (Sec. 20-7): base standard 7 feet tall, 40 square feet per face, 10 feet back from the right-of-way, one per parcel, with modifiers: subtract 8 square feet in residential, TND, CF, O-1, and C-1 districts; add 20 square feet and one extra sign for 300 plus feet of major-road frontage; add 2 feet of height and 24 square feet on rights-of-way of 120 feet or more; add 20 square feet for multi-tenant parcels. Electronic portions are capped at 60 percent of permitted area.
