In the event of an appeal of the denial of a permit under this Subsection
C, the Zoning Board of Appeals shall fix a time and place for the hearing of said appeal in the same manner as that established for other appeals to the Board; said hearing to be held not more than 40 days after such appeal is filed, unless the Board, in its discretion, extends the time for hearing upon motion of the appellant or City Attorney. If the land within such mapped street, alley, parkway, highway or expressway is not yielding a fair return, the Zoning Board of Appeals shall have power in a specific case, by the vote of a majority of its members, to grant a permit for a building in such street, alley, parkway, highway or expressway, which will as little as practicable increase the cost of opening such street, alley, parkway, highway or expressway, or tend to cause a change of such Official Map. The Board may also impose reasonable requirements as a condition of granting such permit where the board finds they are reasonably necessary to promote the health, convenience, safety or general welfare of the community. Notwithstanding any provision of this subsection to the contrary, the Board shall refuse a permit where the applicant will not be substantially damaged by placing his building outside the mapped street, alley, parkway, highway or expressway. Before taking any action authorized in this subsection, the Board of Appeals shall hold a hearing at which parties in interest and others shall have an opportunity to be heard. At least 15 days before the hearing, notice of the time and place of the hearing shall be provided to the applicant and published as a Class 1 notice, under Ch.
985, Wis. Stats. Any decision by the board under this subsection shall be subject to review by commencement of a certiorari action within 30 days of the date of the Board's decision in the same manner and pursuant to the same provisions as in appeals from the decisions of a board of appeals of zoning matters under this Chapter
455.
