Where a building setback line has been established on at least 50% of the properties in a block, or within 150 feet of a proposed building or development, that does not conform with the requirements of this Part, the required setback distance may be varied at the discretion of the Zoning Officer. In no case shall tree required distance be less than the average existing setbacks in either instance.
