Except as herein otherwise provided, buildings required to be numbered, lying north of a line parallel to and 400 feet north of the north line of Florida Avenue and the north line of Florida Avenue projected easterly and westerly to the eastern and western limits of the city, and erected upon lots which abut on streets or avenues running northerly and southerly, shall be numbered southerly toward said line, allowing 100 numbers to each block, both sides of a street or avenue being considered a block, the even numbers to be used for numbering buildings on the west side of said streets and avenues and odd numbers to be used for such numbering on the east side of said streets and avenues. The first tier of blocks north of said line shall be numbered southerly, beginning with the number 1400 on the west side of the streets and avenues (and at the northeast corner of said blocks) and with the number 1401 on the east side of the streets and avenues (and at the northwest corner of said blocks). The second tier of blocks north of said line shall be numbered southerly, beginning with the number 1300 on the west side (and at the northeast corner of said blocks) and the number 1301 on the east side (and at the northwest corner of said blocks) of said streets and avenues, and continuing in like manner, each successive tier of blocks lying north of said line shall be numbered southerly, giving 100 numbers to each block, the lowest numbers starting at the north line of said blocks, and each tier of blocks taking numbers 100 lower than the tier of blocks lying immediately south of such tier of blocks.
