Section 106 of the National Historic Preservation Act seeks to accommodate historic preservation concerns with the needs of federal undertakings. A Determination of Eligibility Report has identified those above-ground historic resources within the project area that are listed or eligible for inclusion in the National Register of Historic Places (NRHP). The Pennsylvania Department of Transportation, on behalf of the Federal Highway Administration, delineated the boundaries of this project area, also known as the Area of Potential Effect. Within that area, all buildings, structures, sites, and objects 50 years in age or older—above and below ground—were surveyed for their eligibility for inclusion in the NRHP. The survey for above-ground properties encompassed a total of 48 resources: 46 were surveyed individually whereas two were surveyed as districts. In addition, two resources were determined previously as eligible for inclusion in the NRHP: The Jacob Reed Homestead at the intersection of Souderton/Hatfield Pike and Township Line Road, and the North Pennsylvania Railroad from Philadelphia to Bethlehem. The project team is conducting below-ground studies for the presence of archaeological resources. Of the 48 above-ground resources surveyed, three were recommended to be eligible for the NRHP. The Determination of Eligibility Report was submitted to the Pennsylvania Historical and Museum Commission (PHMC) in January 2002 for its concurrence with these findings. Concurrence from the PHMC was received in April, 2002. PENNDOT's project team has assessed what effects the Sumneytown Pike/PA 309 Connector project will have on the NRHP-eligible resources. Three levels of findings may be determined based on the application of federal criteria: No Effect, No Adverse Effect, or Adverse Effect. This project was determined to have a No Adverse Effect on the historic properties in the study area.
