AFC Environmental Studies

The Federal Highway Administration (FHWA), under the National Environmental Policy Act (NEPA), requires that all federally funded highway projects undergo an environmental review to identify potential impacts. Some of the activities included in the environmental review process are:

  • Identification and evaluation of impacts to historic structures and properties
  • Exploration of project area to determine the presence of historic and pre-contact archaeological resources
  • Identification and possible mitigation of hazardous material sites
  • Evaluation of potential impacts to parkland and recreational areas
  • Identification and possible protection of threatened and endangered species in the project area
  • Identification and minimization of negative impacts to air, noise, and water quality in the project area and surrounding neighborhoods

See below for the status and key findings of the CPR Environmental Studies.

Noise Sensitive Areas (NSA)

NSAs are noise sensitive areas where noise levels will be evaluated. Preliminary noise studies have been completed identifying areas that qualify for noise walls if they are desired by the community. Individual community meetings will be held during Final Design to review results and discuss options for noise wall locations and designs.

Historic Structures and Properties

With all transportation projects involving historic resources, PennDOT first evaluates whether or not it can avoid impacting the historic or cultural resource altogether. If it cannot, options that would “minimize” the impact or “mitigate” its impacts are reviewed. When a project results in the use of a historic property, a Determination of Effect Report is prepared to determine the effect the project may have on the resource. If the effect is determined to be adverse, a Memorandum of Agreement is prepared to mitigate for the adverse effect.

Where We Are

  • Historic Resource studies have been carried out, identifying individual buildings and districts eligible for inclusion on the National Register of Historic Places. These now have PennDOT’s and PHMC’s concurrence. For further information on the status of these documents visit: www.paprojectpath.org/ProjectDetails.aspx?ProjectID=2427
