What We Do
A Project Development and Environment (PD&E) study is an environmental and engineering process developed by the Florida Department of Transportation (FDOT) to determine social, economic, natural and physical environmental impacts associated with a proposed transportation improvement project.
The process follows procedures set forth in the National Environmental Policy Act of 1969 and federal and state laws and regulations. It requires the combined efforts of professional engineers, planners and scientists who collect and analyze project-related information to develop the best solution for transportation needs.
Public involvement is a key component of this process and various meetings are held with businesses, interested keyholders, community groups, traveling public, homeowners and the general public to receive input on the project.
SR 78 PD&E Study
Client: FDOT District 1
Location: Lee County, FL
Our team was responsible for performing a PD&E study to evaluate the widening of SR 78 (at I-75 to SR 31) from two to four lanes. Other improvements included drainage, bridge widening, access management, traffic operations, safety, and the addition of a shared use path.
Osiris 9 Consulting developed conceptual widening alternatives, drainage improvements, an access management plan, and intersection improvements as well as writing the Preliminary Engineering Report, Project Traffic Analysis Report and Type 2 Categorical Exclusion.
US17 PD&E Study
Client: FDOT District 2
Location: Nassau County, FL
Our team conducted an Intersection Control Evaluation for the stop-controlled intersection of US 17 at William Burgess Boulevard. Proposed intersection alternatives which were evaluated included a typical signalized intersection, a partial Median U-Turn (MUT), and a hybrid Quadrant/MUT intersection.
The evaluation for each alternative included delay, safety benefits, construction and right-of-way costs, and benefit-cost ratio. Osiris 9 completed Stage 1 and Stage 2 of the ICE process and the analysis was approved by FDOT in November 2020.
