The Chester County Planning Commission is responsible for completing plan reviews under the Municipalities Planning Code (Act 247) and the Sewage Facilities Act (Act 537). The reviews evaluate proposed municipal comprehensive plans, zoning ordinances, subdivision ordinances, and sewage facilities plans as well as proposed subdivision and land development site plans to assess their consistency with county planning policies and goals. Other reviews handled by the Planning Commission include NPDES (Act 67/68) reviews, Agricultural Security Area reviews, and pipeline related reviews.

This service is offered free of charge and it brings the municipality and developer together to create a better community. Planning Commission staff is available to meet to discuss sketch plans and will provide an informal review of the plan. Plans can also be submitted to our office using the standard plan submittal process and Act 247 Referral application and choose "Unofficial Sketch Plan" under Type of Review Requested.
