## § 6-303 Boundary line determination.

Balt., Md., Code art. 32, § 6-303 (2026)

(a) The precise location of a zoning district boundary line is determined as specified in this section.

(b) Where a district boundary line is shown as being within or along a street, alley, other public or private way, or an extension of any of them, or as being within or along a non-navigable stream, the boundary is the center line of that street, alley, other way, extension, or stream.

(c) Where a district boundary line is shown as along or superimposed on a lot line, the boundary is that lot line.

(d) Where the location of a district boundary line is indicated by a designated number of feet, that distance controls.

(e) Where a district boundary line is shown as being within or along a railroad right-of-way, the boundary line of that railroad right-of-way controls.

(f) Where a district boundary line is shown as along a navigable waterway and is not otherwise fixed, the boundary is:

  (1) the line that coincides with the “pierhead line” (that is, the legal boundary beyond which artificial structures, such as piers, may not project); or

  (2) where no pierhead line has been established, the line that coincides with the mean low tide line.

(g) Unless otherwise indicated on the zoning map, submerged land that is later reclaimed is in the same district as the non-submerged premises to which the reclaimed land is contiguous.

(h) Where a district boundary line is shown and its location is not fixed by any of the rules of this section, its precise location is determined by scaling from fixtures, objects, or other structures shown on the zoning map.
