San Martin Blvd. Bridge Replacement Study Project Development and Environment Process

The National Environmental Policy Act of 1969 (NEPA) requires all projects receiving federal funding to evaluate and consider alternatives which minimize adverse impacts to the natural and physical environment and to the community. The Federal Highway Administration describes the NEPA process as “an approach to balanced transportation decision making that takes into account the potential impacts on the human and natural environment and the public’s need for safe and efficient transportation.”

Adequate opportunity for the community to comment and provide input during the study process is required. The Project Development and Environment or “PD&E” process assures that NEPA requirements are met and that design and/or construction of the project will be eligible for federal funds, if available.

PD&E Study

The study will evaluate possible impacts to the following:

  • Wetlands                                
  • Wildlife
  • Water Quality
  • Historic and Archeological Sites
  • Recreation Areas
  • Noise Sensitive Sites
  • Air Quality
  • Hazardous Materials

Additional issues that will be evaluated and considered include:

  • Community Impacts
  • Impacts to traffic on local roads during construction
  • Bicycle and pedestrian facilities and safety
  • Project Costs
  • Motorist Safety
  • Impacts to Navigation
  • Aesthetics/Landscaping

Input from the community is an important factor in the decision-making process. The study will include many opportunities for public involvement and input.


The key steps in the process include:

  • Collect and analyze data.
  • Develop and ealuate alternatives.
  • Present alternatives to the community and request input.
  • Select a recommended alternative.
  • Document the study process in reports.
  • Present recommended alternative to the community.
  • Obtain approval from the Federal Highway Administration.
