Efforts of local business leaders to promote development were rewarded in 2005, with a $2.4 million grant and low-interest loan package to develop Pawling Station Business Park. It is a 48-acre (190,000 m) site along Route 522 in Penn Township, that will feature three to 6-acre (24,000 m) lots with storm water drainage. An 18-member volunteer task force will oversee the construction of Pawling Park. The task force includes Pennsylvania Senator John Gordner and Rep Russ Fairchild, community leaders with a wide range of economic development experience and skills including an accountant, lawyer, land developer, engineer, surveyor, and two bankers – along with chairmen of the Snyder County Board of Commissioners, Penn Township Board of Supervisors, and Township Municipal Authority.

Major employers in the region include a significant number of housing related manufacturers, state facilities, as well as local government entities like the school district. With the decline in housing manufacturing in 2007 several local factories have closed displacing about 250 workers. Additionally there is a rising vacancy rate for commercial retail property along the routes 11 & 15 highway.

A thirty-year effort to develop a bypass of the rte 11& 15 commercial area, called the Central Susquehanna Thruway, has been delayed until 2009 due to minimal funding from the state or federal government.
