(a)

Establishment of the Official Zoning Map .....

(1)

The location and boundaries of the zones established by this Code are shown and maintained as part of the Geographic Information System (GIS) of the Chattanooga-Hamilton County Regional Planning Agency (RPA). The RPA also has the responsibility for maintenance of the Official Zoning Map. .....

(2)

The zoning GIS layer constitutes the City of Chattanooga's Official Zoning Map and is incorporated into, and the same is made a part of this Code by reference, and upon its introduction and passage, is an effective and operative part thereof. .....

(3)

The Executive Director of the Regional Planning Agency, or their designee, will revise the Official Zoning Map when amendments are passed by the governing body. .....

(4)

No unauthorized person may alter or modify the Official Zoning Map. Errors in the Official Zoning Map will be corrected as they are discovered, and the corrected information shown on the GIS system. .....

(b)

Interpretation of Boundary Lines .....

(1)

Where a zone boundary line is shown as being within or along a public or private right-of-way, or an extension, or as being within or along a non-navigable stream, the boundary is the centerline of that right-of-way, or extension, or stream. .....

(2)

When a public or private right-of-way is abandoned then the new zone boundary line is the prior centerline of that former right-of-way. .....

(3)

When a public or private right-of-way is abandoned then the new zone boundary line is the prior centerline of that former right-of-way. .....

(4)

Where a zone boundary line is shown as along a lot line, the boundary is that lot line. .....

(5)

Where the location of a zone boundary line is designated by a number of feet, that distance controls. .....

(6)

Where a zone boundary line is shown as being along a railroad right-of-way, the boundary line of that railroad right-of-way controls. .....

(7)

Where a zone boundary line is shown as along a navigable waterway and is not otherwise fixed, the boundary is the centerline of the waterway. .....

(8)

Unless specified otherwise by the amending ordinance, overlay zone boundaries on the Official Zoning Map that approximately follow zone lines are interpreted as being coincident with those zone lines. .....

(9)

Where the application of the interpretation rules leaves a reasonable doubt as to the boundaries between two zones, the regulations of the more restrictive zone govern the entire parcel in question, unless otherwise determined by the Board of Appeals. .....

(c)

Administrative Mapping Errors .....

Where it is determined that due to an administrative error, the Official Zoning Map zone boundary which encompasses property that was never intended to be included or fails to depict property which was intended to be included in the zone boundary, and such determination is supported by official documentation, the Executive Director of the Regional Planning Agency, or their designee, may modify the Official Zoning Map to accurately reflect the proper zone boundary.

(Ord. No. 14137, § 1, 7-23-24; Ord. No. 14138, § 1, 7-23-24; Ord. No. 14297, § 1, 12-2-25; Ord. No. 14297, § 1, 12-2-25)

Property annexed to the City of Chattanooga shall be temporarily reclassified from its former zoning classification to its most equivalent zone.

The Planning Commission, within 90 days of the effective date of annexation, will recommend a zoning plan for newly annexed areas of the City to the City Council. Following the receipt of the Planning Commission recommendation, the City Council, after giving notice as required in Article XV regarding amendments, will adopt a zoning plan as an amendment to the Official Zoning Map for the newly annexed area.
