Planning in Pennsylvania

First, and foremost, it is important that you become familiar with the rules that guide planning in your municipality. State enabling legislation has been passed that governs planning in Pennsylvania. It guides how local planning commissions operate, as well as the plans and ordinances that are developed to implement the plan.

The legislation is known as the Pennsylvania Municipalities Planning Code, Act 247. This legislation goes by several names, including the MPC, Act 247 and the Planning Code. You can download the most recent version of the MPC through this webpage.

Having a general understanding of the Municipalities Planning Code can go a long way to assisting you in performing your duties as a planning commissioner. All planning commission members are encouraged to obtain a copy and keep it with them during all meetings of the planning commission.

Planning Agencies

Article 2 of the Planning Code establishes the rules for creating a planning commission and how they will function. The governing body, consisting of either the board of supervisors, borough council or board of commissioners, is provided the power to establish a planning commission. The planning commission serves on their behalf. It should be noted that not all municipalities in Pennsylvania have planning commissions.

The Article defines the core aspects of the planning commission:

Subdivision & Land Development

Article 5 of the Planning Code governs the creation and administration of a subdivision and land development ordinance. A subdivision and land development ordinance is a regulatory tool that helps implement the comprehensive plan. The ordinance governs the process of subdividing land into parcels.

Much of the activity of municipal planning commissions centers on the review of subdivision and land development applications. Applications should be reviewed not only for compliance with ordinances but also consistency with the municipal comprehensive plan. The planning commission is typically provided with professional assistance from the municipal engineer and solicitor serving the municipality, and often from a land planning consultant.
