Base districts. The boundaries of all base districts shall be shown on the map made part of this chapter. This map shall be known as the "Zoning Map of Sadsbury Township." The map and its notations, references and data shown thereon are hereby incorporated by reference into this chapter, and shall be as much a part hereof as if all were fully described herein. Whenever an amendment of this chapter involving a change of district boundaries is approved by the Board of Supervisors, said change shall be recorded on the master Zoning Map of Sadsbury Township, said change shall be recorded on the master Zoning Map of Sadsbury Township as maintained at the Township offices and updated from time to time.

Overlay districts. The Airport, Floodplain, Steep Slope, Resource Conservation, Special Sadsburyville Village and Traditional Neighborhood Development Districts shall be treated as overlay districts to the otherwise applicable base zoning district. The provisions applicable to overlay districts are described in Article XII herein.

If, in accordance with the provisions of this chapter and the Pennsylvania Municipalities Planning Code, as amended,[1] changes are made in district boundaries, they shall be entered on the Zoning Map promptly after the amendment has been approved by the Board of Supervisors.

Editor's Note: See 53 P.S. § 10101 et seq.
B. 
No changes of any nature shall be made to the Zoning Map or notations, references or other data shown thereon except in conformity with the procedures set forth in this chapter or any commonwealth law, if applicable. All changes shall be noted on the Zoning Map by date with a brief description of the nature of the change.
The Zoning Map shall be located in a place as designated by the Board of Supervisors and shall be the final authority as to the current zoning status of land and water areas in the Township, regardless of unofficial copies which may have been made or published from time to time. A copy shall be included in this chapter.[1]
A. 
The Board of Supervisors may, by resolution, adopt a new Zoning Map which will supersede the prior Zoning Map. However, no such correction shall have the effect of amending the original Zoning Map or any subsequent amendment thereof. The new Zoning Map shall be identified by the signatures of the Board of Supervisors, attested by the Secretary of that body, and bearing the following words: "This is to certify that this Zoning Map supersedes all previously adopted Zoning Maps of Sadsbury Township, Chester County, Pennsylvania."
B. 
Unless the prior Zoning Map has been lost or totally destroyed, the prior map or any significant parts thereof with all available records pertaining to its adoption or amendment.
Where uncertainty exists as to the boundaries of districts, the following rules shall apply:
A. 
Designation of district boundaries. Boundaries indicated as approximately following the center line of a street, highway, alley, railroad right-of-way, stream, existing lot or other property line shall be construed to be such boundary. Where a district boundary line does not follow such a line, position is shown on said Zoning Map by a specific dimension expressing its distance, in feet, from a street right-of-way line or other boundary line as indicated and running parallel thereto.
B. 
Determination of location of boundaries. Where physical or cultural features existing on the ground are at variance with those shown on the Zoning Map, or if uncertainty exists as to the true location of a district boundary line in a particular instance, the Zoning Officer, after a consultation with the Township Engineer, shall render a determination.
C. 
Determination of overlay district boundaries. The criteria for determining the extent of the Airport District, Floodplain District, Steep Slope District and Resource Conservation District are contained in Article XII. Uncertainties shall be resolved by the Zoning Officer in consultation with the Township Engineer.
D. 
Boundary tolerance. Where a lot is divided by a district boundary line, other than a boundary line of an overlay district, the uses permitted in the less restrictive district may extend into that portion of said lot in the more restrictive to either the nearest lot line or a distance of 50 feet, whichever is less. In no case shall a use be allowed to extend into the more restrictive district unless full use is made of the less restricted area before extension. Any extension of a use into the more restrictive area must meet the area and bulk requirements of the more restrictive district. In no case shall the uses and area and bulk requirements permitted in an abutting district be extended for any distance into a Floodplain District.
