Every parcel, lot, and tract of land within the City of Dallas is designated with a land use (zoning) district. The use of land is limited to the uses allowed by the applicable land use district and subject to applicable land use regulations. The applicable land use districts and regulations are determined based on the Land Use District Map and the provisions of this Chapter, which shall be consistent with the City of Dallas Comprehensive Plan Map designation, as indicated in Table 2.1.010.

Table 2.1.020

1. Consistency with Land Use District Map. The boundaries of the land use districts contained within this chapter shall coincide with the land use district boundaries identified on the City’s official zoning map, retained by the City Recorder. Said map by this reference is made a part of this Development Code. The official zoning map, and any map amendments, shall be maintained by the City.
2. Applicability of land use standards. Each lot, tract, and parcel of land or portion thereof within the land use district boundaries designated and marked on the zoning map, is classified, zoned and limited to the uses hereinafter specified and defined for the applicable land use district.

Where due to the scale, lack of scale, lack of detail or illegibility of the City zoning map, or due to any other reason, there is uncertainty, contradiction or conflict as to the intended location of a district boundary line, the boundary line shall be determined by the Planning Official in accordance with all of the following criteria:

1. Rights-of-way. Boundaries indicated as approximately following the centerlines of streets, highways, railroad tracks, alleys, irrigation canals, bridges or other right-of-way shall be construed to follow such centerlines. Whenever any public right-of-way is lawfully vacated, the lands formerly within the vacated right-of-way shall automatically be subject to the same land use district designation that is applicable to lands abutting the vacated areas. In cases where the right-of-way formerly served as a land use district boundary, the lands within the right-of-way now vacated shall be allocated proportionately among the subject land use districts;
   
2. Parcel, lot, tract. Boundaries indicated as approximately following the boundaries of a parcel, lot, or tract shall be construed as following such boundaries;
3. Jurisdiction boundary. Boundaries indicated as approximately following a City or County boundary, or the Urban Growth Boundary, shall be construed as following said boundary; and
4. Natural features. Boundaries indicated as approximately following a river, stream, drainage channel, drainage basin, topographic contour or other changeable natural feature not corresponding to any feature listed in subsection A-C, above, shall be construed as following such feature, except that the location may be corrected administratively through a Type II (Code Interpretation) procedure, in accordance with Chapter 4.8
