FAQs (Frequently Asked Questions)

What is a PD&E Study?
A Project Development and Environment (PD&E) Study is a phase of the Florida Department of Transportation's (FDOT) highway development process. A PD&E Study assists the FDOT in determining the location, conceptual design and social, economic and environmental effects of proposed roadway improvements. The process follows procedures set forth in the National Environmental Policy Act of 1969 and federal and state laws and regulations. During the PD&E Study process, feasible alternatives are developed for roadway improvement projects. These "Build" alternatives are evaluated based on environmental, engineering and socioeconomic conditions, safety needs and public input. The need for additional right-of-way for capacity improvements or stormwater will also be evaluated during the PD&E Study phase. The "No Build" alternative is evaluated throughout the study process. This "No Build" alternative leaves the existing transportation infrastructure as it is, with only routine maintenance as required. If the study results in a "Build" alternative being selected, the project may proceed to the next phase, which is the design phase. The basic activities of a PD&E Study include:

Data Collection
The first major work effort is the collection of all available data pertaining to the study corridor including existing infrastructure, traffic counts, existing and future land uses, drainage patterns, locations of wetlands and habitat for threatened or endangered species, and potential contamination sites.

Alternatives Development and Analysis
Once data collection is completed, the Department develops and evaluates various alignment alternatives, including a “No Build” alternative. The “No Build” alternative assumes no improvements other than routine maintenance through 2040. The environmental impacts, social impacts and costs of these alternatives are quantified and summarized in an evaluation matrix.

Public Kick-off Meeting
A public kick-off meeting is held to introduce the project to the public and provide an opportunity to view and comment on the project’s need and objectives. With input received at the public kick-off meeting, the project team develops alternatives to present to the public at the alternatives public meeting.

Alternatives Public Meeting
Combining the public input with the needs of the corridor, several improvement alternatives are developed and evaluated along with the “No Build” alternative (which leaves the corridor as is) during the PD&E Study. This meeting presents the environmental and social impacts as well as estimated costs of the roadway alternatives as compared to the “No Build” alternative. The public is provided with an opportunity to view and comment on the alternatives under consideration.

Public Hearing
After all public comments are reviewed and the analysis of the alternatives has been refined, a formal public hearing is held to provide a forum for input from property owners and interested parties on the final recommendations. A final decision is not made until after the public hearing.

Final Acceptance
After the comments from the public hearing have been received, considered and addressed, the project reports will be finalized and submitted to the Florida Department of Transportation Secretary. Once acceptance is granted, the PD&E Study phase of the project will be complete. The phases that follow the PD&E Study are design of the project, acquisition of right-of-way, if necessary, and construction of the improvements.
