For the purpose of this chapter, the Township of Logan is divided into the following eight classes of districts:

The boundaries of these districts and classes of districts are hereby established on a map entitled "Zoning Map for Logan Township," which map accompanies and is hereby declared to be a part of this chapter.

Except when otherwise indicated by dimensions of fixed boundaries shown on the Zoning Map, the depth of residential and business frontage is established, for the purpose of this chapter, at 150 feet.

Where a district boundary line divides a lot in single ownership, existing at the time of enactment of this chapter, the use authorized on, and the district requirement of, the least restricted portion of such lot shall be construed as extending to the entire lot, provided, that such extension shall not include any part of the lot which is more than 50 feet from the district boundary line.

The procedures for amendment, supplement and/or change in the boundaries of any zoning district and/or the Zoning Map for Logan Township shall be in accordance with the Pennsylvania Municipalities Planning Code (hereinafter "Code") as amended from time to time.

Any such amendment, supplement and/or change in the boundaries of any zoning district and/or the Zoning Map may be initiated by:

If a petition for rezoning is denied by the Board of Supervisors once in a one-year period, another petition for a change to the same zone district and/or area of the Zoning Map shall not be filed within a period of one year from the date of denial, except upon the initiation of the Township Supervisors or after a showing of a change of circumstances which would warrant a rehearing. Determination as to a change in circumstances shall be made in the sole discretion of the said Board of Supervisors.
