What is a PD&E Study?

A Project Development and Environment (PD&E) study is conducted to meet the requirements of the National Environmental Policy Act. During the study, we determine the location and conceptual design of feasible build alternatives for roadway improvements and their social, economic, and environmental effects. A PD&E study is finalized when the Federal Highway Administration, reviews the documentation and recommendations then provides a Location and Design Concept Acceptance.

Five Steps in the Transportation Development Process

  1. Long Range Planning: The FDOT and local governments conduct long-range transportation planning on an ongoing basis to identify and prioritize individual projects.
  2. PD&E Study: During this step, various roadway improvement alternatives and their social and environmental effects are examined.
  3. Design: During design, detailed construction plans are prepared.
  4. Right-Of-Way Acquisition: This phase entails acquisition of necessary right-of-way, based on the construction plans.
  5. Construction: The roadway is built during this phase.

The US 19 project has completed the PD&E study phase and is moving into the design phase of the FDOT’s 5-step highway development process. A PD&E study assists the FDOT in determining the location, conceptual design and social, economic and environmental effects of the proposed improvement. 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 stormwater and environmental mitigation is also evaluated during the PD&E study phase.

What is a PD&E Study Re-evaluation?

A re-evaluation is the process used to document compliance with federal laws and to identify any changes that may have occurred since the approval of the original final environmental document. The re-evaluation is needed for the purpose of updating the 1996 study, documenting changes in the current design standards, reassessing socio-economic and environmental impacts, and comparing any new alternative options with the previously approved roadway improvement.

What’s New?

The Florida Department of Transportation (FDOT) completed a Project Development & Environment (PD&E) Re-evaluation Study for proposed improvements to US 19 (SR 55) from 66th Avenue North to SR 690 / 118th Avenue North in Pinellas County. This project is a re-evaluation of a PD&E study originally completed in 1990. Re-evaluations verify that the study results are in compliance with applicable Federal and State laws before moving into a production phase for the area. This re-evaluation serves as a check on the commitments made by FDOT during the original study process. The re-evaluation documents compliance with Federal laws and any changes that may have occurred since the approval of the original final recommendations.

Project Schedule

The US 19 PD&E Re-evaluation Study began in February 2016. The project activities included collecting information, developing roadway improvement alternatives and evaluating the potential environmental and social effects of the “no-build” and “build” alternatives.


A public hearing was conducted on Tuesday, October 30, 2018 from 5:30 p.m. to 7:30 p.m. at the Tampa Bay Regional Planning Council.


On October 30, 2019, FDOT’s Office of Environmental Management (OEM) approved the US 19 PD&E Re-evaluation.
