The Southeastern Pennsylvania (SEPA) First Suburbs Project is a coalition of community organizations and institutions focused on solving common challenges facing the older, developed suburbs of Bucks, Chester, Delaware, and Montgomery Counties. These communities share conditions of diminishing economic investment, declining infrastructure, struggling school districts, and social services lagging behind the needs of their residents. Left to solve these problems on a municipal-by-municipal basis, these communities will continue to decline, reducing the quality of life for the Southeastern region of Pennsylvania as a whole.

The core belief of the SEPA First Suburbs Project is that state policy changes and regional solutions will best address these common challenges by using limited resources more efficiently to the benefit of all of the residents of Southeastern Pennsylvania.
