Urban growth boundaries are used to demarcate where government intends to encourage and discourage land development. This guide provides links to resources about urban growth boundaries, as well as examples from Pennsylvania municipalities.
Governments use urban growth boundaries (UGBs) to demarcate where they intend to encourage and discourage land development through their public-infrastructure investments, land-use regulations, land acquisitions, and other actions. Within the urban growth boundary—called the designated growth area or urban growth area—government policy encourages relatively high-density development. Outside the UGB, government policy encourages conservation of agricultural lands and working forests and the protection of natural areas. UGBs are designed to accommodate growth for a specific period of time (often 20–30 years) and can be implemented on a local or regional scale.
Below are links to resources that provide more detailed information about UGBs, as well as examples from Pennsylvania municipalities.
