Project Development & Environmental (PD&E) Studies

Florida’s 20.5M residents, 116M annual visitors and continued growth creates an on-going challenge for our transportation authorities to manage the state’s roadways. PD&E studies are an important process used to help plan for this growing demand on Florida’s transportation network. Prosser | PRIME AE is proud to have performed PD&E studies throughout the state.

Our integrated design team of Transportation Planners, Traffic Operations Experts and Roadway Designers ensures our alternatives are thoughtful, thorough, and implementable. Our analysis also factors rapidly changing advances in technology and transportation, understanding roads being planned today need to be able to implement the technology of tomorrow.

The Prosser | PRIME AE formula of proven professionals, unique alternatives, integrated design teams, and embracing new technologies ensures our clients plan and build roadway infrastructure that will impact today and evolve with tomorrow.

About PD&E Studies

PD&E Studies are conducted by state and local highway authorities during the planning stages of major roadway projects to comply with requirements of the National Environmental Policy Act (NEPA). These studies first identify a location and develop a conceptual design for multiple alternatives and then evaluate social, economic, and environmental effects of each alternative compared to a “no-build” alternative. The results are documented and finalized with approval in the form of a Location and Design Concept Acceptance (LDCA) letter. If federal funds are not used, a similar evaluation is performed in a State Environmental Impact Report (SEIR) study or a Non-major State Action (NMSA) evaluation and the recommendations are approved by the FDOT.

While every major roadway improvement in Florida will be evaluated through one of these studies, each study is as unique as the roadway corridor they look to improve. Impacts to traffic, aesthetics, archeological and historic resources, wetlands, flood plains, and air quality are some of the many factors that are evaluated to ensure the proposed improvements benefit the general public.
