The height of the dwelling shall be reduced in direct proportion to the percentage of the shortfall of the required lot width.
Example: If the minimum lot width in the zone is fifty (50') feet, and the nonconforming lot has a lot width of only forty (40') feet, the height of the building shall be reduced by 50 feet - 40 feet/50 feet = 20%. If the maximum height permitted in the zone is thirty-five (35') feet, the maximum height on this nonconforming lot would be twenty-eight (28') feet.
