Grissom-Widening-PSJ-Fay-30-PER-App3-Traf-20250225.pdf

This is a Traffic Impact Analysis Appendix document prepared for the Grissom Parkway Widening project in Florida, supporting the professional engineering design services contract opportunity. The project involves the widening of Grissom Parkway from two lanes to four lanes by adding one additional lane in each direction with a median-separated roadway configuration. The design must accommodate turning movements throughout the corridor and include roundabout evaluation. The County requires a phased construction approach with a minimum of two phases and transitional plans, incorporating stormwater management and pedestrian improvements. A phased right-of-way acquisition approach is also anticipated based on funding availability. All design documents must be prepared, signed, and sealed by design professionals licensed in Florida and employed by or retained by the contractor. The design shall comply with National Environmental Policy Act (NEPA) requirements to maintain eligibility for potential Federal funding.

The traffic impact analysis appendix provides technical support for the overall project design requirements and engineering considerations. The document serves as a component of the broader professional services package necessary to advance this infrastructure improvement project. Design professionals and contractors must demonstrate expertise in roadway design, traffic engineering, NEPA compliance, and phased project development. The analysis informs the feasibility and configuration of the widening project while supporting the County's objectives for phased implementation and coordinated right-of-way acquisition aligned with available funding sources.
