About the Study


A Project Development and Environment (PD&E) Study is a process conducted by the Florida Department of Transportation (FDOT) to determine the environmental, social, and economic impacts that are associated with proposed transportation improvements. The process, mandated by the National Environmental Policy Act (NEPA), is a combined effort by professional engineers, planners, environmental scientists, and others who analyze the project-related information to develop the best alternative for a community’s transportation needs.  The public will be involved throughout the entire study process.

The FDOT is conducting this PD&E Study to evaluate the need to enhance overall traffic operations at the existing interchanges of SR-9/I-95 at SR-804/Boynton Beach Boulevard and SR-9/I-95 at Gateway Boulevard by providing improvements to achieve acceptable Level of Service (LOS) at both interchanges in Design Year 2045. Conditions along Gateway Boulevard and Boynton Beach Boulevard are anticipated to deteriorate below acceptable LOS standards if no improvements are made by 2045. The interchanges will have insufficient capacity to accommodate the projected travel demand. The project would improve the operational capacity and overall traffic operation at the interchanges and study area's roadways/intersections by implementing operational and capacity improvements to meet the future travel demand projected as a result of Palm Beach County population and employment growth.

SR-9/I-95 at SR-804/Boynton Beach Boulevard Interchange

A safety analysis was conducted as part of the development of an I-95/SR-9 Interchange at Boynton Beach Boulevard in Palm Beach County Interchange Concept Development Report. The report included a summary of the crash data and a safety analysis of the project area from 2010 through 2012, which indicated that the northbound on-ramp and the southbound and northbound off-ramps at SR-9/I-95 had higher crash rates as compared to crash rates for similar statewide roadways.

Although the intersections operate at a LOS E or better, under existing conditions, many of the individual turning movements at the intersections (which include the approaches to SR-9/I-95) operate at a LOS F during peak periods. Without the proposed improvements, the intersections will continue to experience delays and queuing, and operate below acceptable LOS standards. The proposed interchange improvements are anticipated to provide additional storage lengths, which will reduce conflict points and the potential occurrence of rear-end collisions.

SR-9/I-95 at Gateway Boulevard Interchange

A safety analysis was included as part of the I-95/SR-9 Interchange at Gateway Boulevard in Palm Beach County Interchange Concept Development Report.  The analysis provided a summary of the crash data and results for the three-year period from 2010 through 2012. No high-crash locations were reported along Gateway Boulevard in the area of the SR-9/I-95 interchange through FDOT’s high-crash location reports. However, SR-9/I-95 in the vicinity of Gateway Boulevard is identified as a high-crash segment, indicating that it has a higher crash rate as compared to crash rates for similar statewide roadways for the same period of time.

Under the existing conditions, all of the intersections within the study area operate at a LOS E or better, with the exception of the High Ridge Road and SR-9/I-95 southbound ramp intersections at Gateway Boulevard. If no improvements are made by 2045, all of the Gateway Boulevard intersections (except the Quantum Lane Intersection) will continue to experience excessive delays and queuing, and operate below acceptable LOS standards during peak periods. The proposed improvements are anticipated to provide additional through lanes and turn lanes, as well as lane assignment signs, to help reduce conflict points and potential occurrence of collisions at the SR-9/I-95 at the Gateway Boulevard Interchange.

Public Involvement Plan

Public involvement is a key component to any PD&E Study.  There will be continuous community outreach and stakeholder coordination throughout the study process. It is anticipated that the following public meetings will be held for this project:

  1. A kick-off meeting will be held with elected/appointed officials and agencies to apprise them of the specific project location, project status and schedule, and to receive their comments.
     
  2. A public kick-off meeting will be held to introduce the project to the local stakeholders and the general public and to solicit local comments and concerns on the potential improvements.
     
  3. An alternatives public meeting will be held to introduce the feasible proposed project alternatives to the general public and solicit their comments and concerns.
     
  4. A formal public hearing will be held near the conclusion of the study process to provide the public a final opportunity to give feedback on the proposed alternatives as well as any potential social, economic, and environmental impacts.

In addition to the scheduled public meetings, it is anticipated that there will be up to three additional meetings held for elected and appointed officials, public agencies, and civic groups. The purpose of these meetings will be to apprise the attendees of the project status and specific location and design concepts, as well as to receive input from the public.
