For over 100 years, local governments have used zoning regulations, enabled by the police powers delegated from the states, to implement plans for the development of their communities. For just as long, objectors have challenged zoning regulations as exceeding this authority. The Commonwealth Court recently upheld such a challenge in Allen Distribution v.

(the MPC), require all zoning measures to be substantially related to the protection and preservation of the public health, safety, morality and welfare interests of its community.
Zoning regulations consist of a zoning map and zoning text. Those documents work in tandem; the map divides the municipality, or municipalities in cases of joint zoning, into “districts” while the text provides regulations for each district, imposes requirements for specific uses and outlines various procedures. Under the MPC, either the municipality or a landowner (including a leaseholder or potential buyer) can propose text and map amendments. The amendment process allows municipalities to improve their ordinances by, for example, adapting them to accommodate new and evolving uses. However, when used in a piecemeal fashion to achieve inconsistent goals, amendments may no longer have a reasonable relationship to the police power they must promote. …
