DELAWARE VALLEY REGIONAL PLANNING COMMISSION

Created in 1965, the Delaware Valley Regional Planning Commission (DVRPC) is an

interstate, intercounty and intercity agency that provides continuing, comprehensive

and coordinated planning to shape a vision for the future growth of the Delaware Valley

region. The region includes Bucks, Chester, Delaware, and Montgomery counties, as

well as the City of Philadelphia, in Pennsylvania; and Burlington, Camden, Gloucester

and Mercer counties in New Jersey. DVRPC provides technical assistance and

services; conducts high priority studies that respond to the requests and demands of

member state and local governments; fosters cooperation among various constituents

to forge a consensus on diverse regional issues; determines and meets the needs of

the private sector; and practices public outreach efforts to promote two-way

communication and public awareness of regional issues and the Commission.

Our logo is adapted from the official DVRPC seal, and is designed as a stylized image

of the Delaware Valley. The outer ring symbolizes the region as a whole, while the

diagonal bar signifies the Delaware River. The two adjoining crescents represent the

Commonwealth of Pennsylvania and the State of New Jersey.

DVRPC is funded by a variety of funding sources including federal grants from the U.S.

Department of Transportation¡¯s Federal Highway Administration (FHWA) and Federal

Transit Administration (FTA), the Pennsylvania and New Jersey departments of

transportation, as well as by DVRPC¡¯s state and local member governments. The

preparation of this document was funded by grants from the Federal Highway

Administration and the Pennsylvania Department of Transportation. The authors,

however, are solely responsible for its findings and conclusions, which may not

represent the official views or policies of the funding agencies.
