Grade levels prevailing at the effective date hereof shall be the official grades for all thoroughfares flanked by one or more houses; provided, however, that, in any block where no houses are located, no grade level will be deemed to exist. Prior to erection of any edifice in any block where no grade level is established, the owner or contractor erecting the edifice shall make application to the Board for the establishment of a grade level. The term GRADE LEVEL, with regard to existing levels, shall be understood to mean the crown of any thoroughfare currently maintained by the village, county or state.
