V.I. Code tit. 29, § 224 (2019)
2019 US Virgin Islands Code|Title 29 - Public Planning and Development|Chapter 3 - Virgin Islands Zoning and Subdivision Law|Subchapter I - Zoning Law|§ 224. Establishment of zoning maps

 Zoning maps  (a) The boundaries and identification of the Zoning Districts established by this law are shown on the Zoning District Maps identified as Document Numbers STZ-1 to 11, SCZ-1 to 20, SJZ-1 to 7, and OIZ-1, inclusive, which are filed in the office of the Lieutenant Governor (with copies in the offices of the Virgin Islands Planning Office). Such maps are hereby declared to be part of this law as fully as if set out herein. No building or land shall be used and no building shall be erected or altered except in conformity with the regulations herein prescribed for the district designated and identified on the Zoning District Map in which such building, land or water is located. Documentation of zoning district maps  (b) The Zoning District Maps shall consist of two (2) identical copies at the time of their adoption. One (1) copy shall be identified as “original copy” and shall not be changed or altered in any manner. The second copy shall be identified as “amendment copy” and shall be kept up-to-date with all subsequent amendments and changes in zoning district boundaries and zoning designations by substituting an amended map for the original map in the “amendment copy”. Any law amending any zoning district map shall be identified by number and date of adoption on the map so amended. Interpretation of zoning district maps  (c)  (1) Zoning district boundaries are shown as heavy solid lines upon the Zoning District Maps and are superimposed upon lighter lines designating Estate lines, platted lot lines, streets and other physically identifiable ground features or extensions of same unless other specific distances in feet or angles, bearings, radii and other references to a boundary location are specified. (2) Zoning District boundary lines when located in streets or other public rights-of-way (guts) shall be interpreted as located in the center line of such rights-of-way. When distances in feet are shown between a Zoning District boundary and a street, the distance shall be interpreted as between the boundary line and the street line unless otherwise specified. (3) Boundary lines which are interrupted to show street names or other identification numbers or letters upon the Zoning Maps shall be interpreted as extending through such identification unless otherwise specified. (4) When the exact location of a Zoning District boundary line is not clear, it shall be determined by the Zoning Administrator, due consideration being given to location as indicated by the scale of the Zoning District Maps. When, for any cause, the streets or alleys on the ground differ from the streets or alleys as shown on the Zoning District Map, the Zoning Administrator may apply the district designations on the map to the streets on the ground in such manner as to conform to the intent and purpose of this law. (5) Where a Zoning District boundary line, shown on the Zoning District Map, divides a lot of record at the time of the adoption of this law, the regulations applying to the district which permits the greater density or intensity of land use activity shall be construed as extending to the entire lot, provided that such extension shall not include any part of such lot more than fifty (50) feet beyond the district boundary line.
