The boundaries of base zoning districts shall be as shown on the map attached hereto and made part of this chapter, which map shall be known as the "Pennsbury Township Zoning Map," and which map, as may be amended from time to time, together with all notations, references and other data shown thereon, shall be as much a part of this chapter as if fully described herein. In addition to the base zoning districts, applicable maps attached hereto and made a part of this chapter and text delineations in this chapter for the Route 1 Corridor and Brandywine Battlefield Overlay District, Flood Hazard Overlay District, and Historic Resource Overlay District of this chapter are hereby adopted as an overlay to the base Zoning Map, and said maps, text delineations, and all notations, references and data shown thereon and therein are hereby incorporated by reference into this chapter and shall be as much a part of this chapter as if all were fully described herein. In addition, the Groundwater Protection Overlay District shall overlay the entire Township and shall be as prescribed in Article XV.

In the case of the Route 1 Corridor and Brandywine Battlefield Overlay District, Groundwater Protection Overlay District, Flood Hazard Overlay District, and the Historic Resources Overlay District, rules for interpretation of district boundaries are contained in Article XII-a, Article XV, Article XVI, and Article XVII, respectively. For all other districts, the boundaries between districts are, unless otherwise indicated, the center lines of streets or such lines extended or lines parallel or perpendicular thereto. Where a district boundary is indicated as approximately following a lot or other property line, or a line designating natural features, such as streams and watercourses, such lot or property line or natural feature designation shall be construed to be such boundary. Where a boundary divides a lot or runs through undivided property, the location of such boundary, unless otherwise specified by dimensions on the Zoning Map, shall be determined by the use of the scale appearing on said map. Where any questions or disagreement may develop concerning the exact location of any district boundary line, the matter shall be decided by the Zoning Hearing Board per procedures established in Article XXIV of this chapter.

Property owned by federal, state, county or local government or their instrumentalities shall be subject to the provisions of this chapter only insofar as permitted by applicable law. Property owned or used by Pennsbury Township shall be exempt from all and shall not be subject to any of the provisions of this chapter.
