§ 6-1. Numbering scheme.
(a) Decimal system.
The houses and buildings within the City shall be numbered according to the decimal system.
(b) Central points.
(1) For streets running generally east and west, the point of commencement shall be at Charles Street, going thence easterly and westerly.
(2) For streets running generally north and south, the point of commencement shall be Baltimore Street, going thence northerly and southerly.
(c) Allocation per block.
100 numbers shall be the proportion for each square, and each successive square shall have its enumeration begin with an even 100.
(d) Beginning elsewhere than Baltimore or Charles.
Where any street does not commence at Baltimore Street or at Charles Street, the enumeration shall conform to other adjacent streets running in the same general direction with an even successive hundred for each additional square, and in all respects adherence to the decimal system shall be observed.
