What We Do


Our Planning Team helps states, regions, counties, and cities develop a long-term vision for its future. The planning process is incredibly diverse and includes land use, transportation, environmental policy, legislation, finance, and public involvement. We bring these diverse elements together, help communities set a long-term vision, and provide the necessary tools and policies to bring that vision to life. 

We examine socio-demographic characteristics and travel patterns for a given area, evaluate how these characteristics will change over a given period of time and evaluate improvements for the transportation system

Our projects vary from a three-block study area to 200-mile corridor. Regardless of size, our process for analyzing travel characteristics and engaging the public and various stakeholders remains the same.

Our team has performed public involvement for FDOT Districts 1, 2, 4, and 5

Our team has analyzed over 300 miles of interstate roadway and 30 interchanges

I-75 N. Master Plan

Client: FDOT District 2

Location: Alachua, Columbia, Hamilton, and Suwannee County, FL

The North I-75 Master Plan was conducted at the request of the I-75 Relief Task Force and was tasked with evaluating capacity and connectivity enhancement to I-75 and three parallel corridors: US 441, US 41, and US 301. The study limits began at the I-75/Florida’s Turnpike Interchange in Sumter County and ended at the I-75/I-10 Interchange in Columbia County.

Osiris 9 Consulting was tasked with traffic analysis, public involvement, and cost estimating, as well as quantifying the impacts of widening the four corridors to the natural, social, physical, and cultural environment. Given the high-level nature of the study, impacts to the environment were quantified using Geographic Information Systems (GIS). 

Over 200 different GIS layers were analyzed to develop a comprehensive picture of impacts. An extensive Public Involvement Plan was implemented to obtain feedback from stakeholders, and several public meetings were held in different locations to obtain public input.

Wekiva Parkway

Client: FDOT District 5

Location: Seminole County, FL

Our team was responsible for developing traffic projections and preparing operation and safety analyses for the Wekiva Parkway (SR 429)/Interstate 4 (I-4) interchange within the City of Sanford. The Wekiva Parkway (SR 429) project is a proposed 4-lane divided limited access toll facility that will connect to SR 417 at I-4, completing the Western Beltway (SR 429) around the Orlando metropolitan area.

Osiris 9 developed traffic projections using the Central Florida Regional Planning Model and demonstrated that the Alternative Technical Concept performed better than or equal to the Request for Proposal concept.

The analysis was documented in an Interchange Modification Report and satisfied the Federal Highway Administration (FHWA) policy points. The project was approved by Florida Department of Transportation (FDOT) District 5, FDOT Central Office, and FHWA in July 2020.

Sebastian Inlet

Client: FDOT District 4

Location: Indian River County, FL

Our team was tasked with determining the vertical clearance of the proposed Sebastian Inlet Bridge. This bridge, also known as the James H. Pruitt Memorial Bridge, connects SR A1A in Brevard County to Indian River County. Osiris 9 reviewed the bridge plans, coordinated with the U.S. Coast Guard, and conducted a Bridge Navigation Survey to document the type and height of the vessels passing underneath the Sebastian Inlet Bridge.
