The Zoning Board of Appeals shall have the power, after an appeal shall be filed with it by the owner of such land, to authorize the granting of a permit for the erection of a building or structure, or part thereof, within the lines of any such mapped street, park, playground or other public grounds in any case in which the Board finds, upon the evidence and arguments presented to it on such appeal, that the entire property of the appellant located in whole or in part within the lines of such mapped street, park, playground or other public ground, cannot yield a reasonable return to the owner unless such permit be granted and that balancing the interest of the city in preserving the integrity of the adopted map and the interest of the owner of the property in the use and benefit of his or her property, the granting of such permit is required by consideration of justice and equity.
