The location and boundaries of the zoning districts are hereby established as shown on a map titled "Zoning Map of the City of Melrose, Massachusetts," dated November 1972, which accompanies and is hereby declared to be a part of this chapter. The authenticity of the Zoning Map shall be identified by the signature of the Mayor, attested by the City Clerk, and the imprinted Seal of the City under the following words: "This is to certify that this is the Zoning Map of the City of Melrose, Massachusetts, referred to in the Zoning Ordinance of the City of Melrose, Massachusetts, which was adopted by the Board of Aldermen on November 27, 1972."
Any change in the location of boundaries of a zoning district hereafter made through the amendment of this chapter shall be indicated by the alteration of such map, such changes to be dated and authenticated as prescribed in § 235-7. The map thus altered is declared to be part of this chapter thus amended. The Building Commissioner shall be responsible for making changes to the Zoning Map. Such changes shall be made within 14 days of the final approval of amendments. The Zoning Map shall be drawn at a scale of one inch equals 650 feet with ink on stable material and shall be located in the office of the Building Commissioner. Photographic reductions of this large-scale map may serve as copies of the Zoning Map.
Where any uncertainty exists with respect to the boundary of any district as shown on the Zoning Map, the following rules apply:
A. 
Where a boundary is indicated as a street, alley, railroad, watercourse or other body of water, it shall be construed to be the center line or middle thereof or, where such boundary approximates a City boundary, then to the limits of the City boundary.
B. 
Where a boundary is indicated as following approximately or parallel to a street, railroad, watercourse or other body of water, it shall be construed to be parallel thereto and at such distance therefrom as shown on the Zoning Map. If no dimension is given, such distance shall be determined by the use of the scale shown on the Zoning Map.
C. 
Where a dimensional boundary or the actual property boundary coincides within 10 feet or less with a lot line, the boundary shall be construed to be the lot line.
D. 
Where a boundary is indicated as intersecting the center line of a street, railroad, watercourse or other water body, and unless it is otherwise indicated, it shall be construed to intersect at right angles to said center line or, in the case of a curved center line, to the tangent to the curve at the point of intersection.
E. 
The abbreviation "PL" means property line as shown on the City Assessors' Map as in effect at the effective date of this chapter. The abbreviation "PL," when used in conjunction with a subsequent amendment to this chapter, shall mean a property line as shown on the City Assessors' Map as in effect at the effective date of such amendment.
F. 
The abbreviation "CL" means center line and "CI" means center of intersection.
