. Size of the Building

  • Building area = 100,000 square feet
  • 1 acre = 43,560 square feet
  • Building in acres =

100,000 / 43,560 = approx 2.3 acres

So the building itself occupies about 2.3 acres.


2. Footprint Dimensions

Assume the building is roughly square.

  • Side length =

\sqrt{100,000} = approx 316 feet per side

So it’s about 316 ft × 316 ft.


3. Add the 1,000-Foot Setback

A setback extends 1,000 feet in every direction around the building.

  • New side length =

316 + (1,000 \times 2) = 2,316 feet per side

So the entire “setback square” is 2,316 ft × 2,316 ft.

4. Area with Setback

  • Total area =

2,316 8 * 2,316 = 5,360, 000 square feet

Convert to acres:

5,361,856 / 43,560 = approx 123.1 acres


5. Extra Land Wasted in Setback

  • Total with setback: 123.1 acres
  • Minus building footprint: 123.1 – 2.3 = 120.8 acres just for buffer.

6. Ratio: Setback Land vs Building Land

  • Ratio =

120.8 / 2.3 = approx 52.5

So the setback consumes about 52 times more land than the building itself.
