Each FDOT transportation project undergoes thorough environmental analysis. Read below to find out more about the environmental process.

What is a Project Development and Environment (PD&E) Study

A project development and environment (PD&E) study is the process FDOT uses to develop transportation projects in compliance with the National Environmental Policy Act (NEPA) of 1969, Title 42 U.S.C. § 4321, et seq., and associated federal and state laws and regulations. The process is outlined in the Project Development and Environment (PD&E) Manual. The PD&E Manual provides support and direction in various technical areas, including engineering analysis, environmental documentation, permitting, and public involvement.  Depending on the complexity of the project, the PD&E process can take anywhere from 6 months to 3 years.  Click here for more information on District Seven’s ongoing PD&E studies.

The PD&E process for a new project typically includes the following elements:

  • Development of the purpose and need statement
  • Preliminary engineering and traffic evaluation
  • Alternatives analysis
  • Environmental analysis
  • Public involvement
  • Agency coordination

Environmental Impact Assessment

Environmental Impact Assessment (EIA) is a process of evaluating the likely environmental impacts of a proposed project or development, taking into account inter-related socio-economic, cultural and human-health impacts, both beneficial and adverse. The efforts are accomplished by working in cooperation with other State and Federal agencies and local governments.

The EIA is an in-depth process that evaluates the potential impacts of a project in the following categories:

Social and Economic

The evaluation of potential social effects explores the potential for project-related effects on the study area population, including displacement or disproportionate effects on special population groups; traffic patterns through neighborhoods; conditions contributing to social relationships and neighborhood interaction; connectivity and access between neighborhoods and community focal points (including the potential of the project to create isolated areas); community cohesion; emergency service response time; and the vision and/or goals of the community.

The areas of assessment include:

  • Social
  • Economic
  • Land Use Changes
  • Mobility
  • Aesthetic Effects
  • Relocation Potential
  • Farmland
Cultural

The purpose of a cultural review assessment is to locate and evaluate archaeological and historical resources within the area of potential impact.  This initiative also includes evaluating potential impacts to recreational areas within the project area.

The areas of impact assessed include:

  • Historic/Archaeological
  • Recreation Areas
  • Section 4(f) Potential
Natural

The evaluation of potential effects on the natural environment explores the potential for project-related effects on the study area wetlands, water quality, drainage and floodplains, as well as impacts on animals and indigenous flora and fauna.  This assessment includes evaluating measures to prevent, reduce or eliminate pollution of ground and surface water, as well as efforts to identify the presence of and to protect threatened or endangered species and their habitat.

Areas of impact evaluated include:

  • Wetlands and Other Surface Waters
  • Aquatic Preserves and Outstanding Florida Waters
  • Water Quality
  • Wild and Scenic Rivers
  • Drainage and Floodplains
  • Coastal Zone Consistency
  • Coastal Barrier Resources
  • Protected Species and Habitat
  • Essential Fish Habitat
Physical

The evaluation of potential effects on the physical environment explores the potential for project-related effects on air quality, noise impacts and other aspects of quality of life.  The review of potential air quality impacts include assessing existing and future conditions and determining if the project conforms with the Clean Air Act. Additionally, qualifying potential noise levels resulting from the project to ensure they meet criteria, and investigate reasonable and feasible noise abatement.  The purpose of this assessment is to avoid, minimize or mitigate potential project impacts

Areas of assessment include:

  • Highway Traffic Noise
  • Air Quality Analysis
  • Contamination
  • Utilities and Railroads
  • Scenic Highways
  • Construction
  • Bicycles and Pedestrians
  • Navigation
