The boundaries of the various districts are shown upon maps entitled "Comprehensive Zoning District Map, City of Donaldsonville, Louisiana." The Zoning District Map (see Plate 1) together will all notations, references and other information thereon, is made a part of this ordinance and has the same force and effect as if fully set forth or described herein.

Where uncertainty exists with respect to the boundaries of any of the aforesaid districts as shown on the zoning district map, the following rules shall apply:

B.

Where the land has been or may hereafter be divided into blocks and lots and where district boundaries are so indicated that they approximately follow the lot lines, such lot lines shall be construed to be said boundaries.

C.

In unsubdivided property or tracts, where a district boundary divides a lot, the location of such boundaries, unless same are indicated by dimensions, shall be determined by use of the scale appearing on such maps.

D.

Where boundaries are indicated as following water courses and other natural topographic features, such lines shall be construed to be such boundaries.

Boundaries indicated as approximately following city limits shall be construed as following such city limits.

F.

Boundaries indicated as following railroad lines shall be construed to be midway between the main tracks.

Boundaries indicated as parallel to or extensions of features indicated in subsections A through E of the above shall be so construed.

Distances not specifically indicated on the official zoning map shall be determined by the scale of the map.
