Zoning district boundary lines are intended to follow or parallel the center line of streets, streams and railroads; and the lot or property lines as they exist on a recorded deed or plan at the time of adoption of this chapter, unless such zoning district boundary lines are fixed by dimensions as shown on the Official Zoning Map.

Where a zoning district boundary is not fixed by dimensions and where it approximately follows lot lines, and does not scale more than 10 feet therefrom, such lot lines shall be construed to be such boundaries unless specifically shown otherwise.

In accordance with § 127-17 of this chapter, if a zoning district boundary line divides a lot held in single and separate ownership prior to the effective date of this chapter, placing 85% or more of the lot area in a particular zoning district, the location of such district boundary line may be construed to include the remaining 15% or less of the lot so divided, subject to the lot of record not being greater than two acres. It shall be the property owner's responsibility to provide documentation to the Zoning Officer to substantiate the location and area of land of the applicable zoning districts for the subject property.

If the guidelines within this section above fail to provide and establish the boundary of a zoning district, a survey of the property or area of land in question shall be made by a registered surveyor, with the cost of the survey paid by the party who is questioning or contesting the boundary location.
