Lowder Street Traffic Impact Study
Location: Lowder ST, MacClenny, FL
Client: Pitman Engineering & Baker County (July 2025 - October 2025)
BCW Engineering was retained to prepare a Transportation Impact Analysis (TIA) for two residential developments — Nehemiah's Court and Barber Pointe — in MacClenny, Baker County, FL. The study assessed the combined traffic impact of both projects on the surrounding roadway network and provided operational analyses and improvement recommendations to support the municipal and county planning process.
Methodology, Data Collection & Existing Conditions
The engagement began with a review of applicable code and comprehensive plan requirements for Baker County and the City of MacClenny, as well as a prior traffic study. A formal methodology statement was prepared and coordinated with the client before proceeding to data collection. Third-party traffic counts were commissioned at the study area intersections during both AM and PM peak periods. Signal timing data for the two existing signalized intersections on W MacClenny Avenue were obtained through direct coordination with FDOT District 2 staff. Existing traffic conditions were modeled using Highway Capacity Software (HCS) for both signalized and unsignalized intersections, and a study area map was prepared in AutoCAD.
Trip Generation, Distribution & Future Demand Forecasting
Trip generation estimates were developed for both developments using the ITE Trip Generation Manual and the OTISS Pro online traffic modeling tool, covering AM peak, PM peak, and weekday scenarios. Future background traffic growth rates were derived from an analysis of FDOT PTMS count station data. Trip distribution and assignment calculations were prepared for each access connection of both developments and applied to the offsite intersection network, with tabulations for background traffic, site-generated traffic, and the combined background-plus-site traffic scenario documented in the report and illustrated through a series of turning movement figures.
Capacity Analysis, Warrant Studies & Recommendations
Level of service analyses were conducted at all study intersections for existing, no-build, and build scenarios using HCS. Right turn lane and left turn lane warrant analyses were performed at the development access connections and at the W North Boulevard intersection with Lowder Street for both AM and PM peak hours. Signal warrant analyses were conducted at the Lowder Street and North Boulevard West intersection using the FDOT signal warrant spreadsheet in accordance with the FDOT Manual of Uniform Traffic Studies, covering existing, peak season adjusted, background, and background-plus-site traffic scenarios. Improvement recommendations — including turn lane and signalization findings — were developed for both developments and documented in the final Transportation Impact Analysis report.
7Brew Spring Hill
LOCATION: County Line RD and Mariner BLVD, Spring Hill, Hernando County, FL
CLIENT: Bowman Group (November 2025 to March 2026)
BCW Engineering was retained to prepare a Transportation Impact Analysis (TIA) for a commercial development in Hernando County, managing the full scope of work from methodology coordination through data collection, traffic modeling, and final report delivery. The study evaluated the development's impact on the surrounding roadway network across three site access connections and a nearby signalized intersection, in accordance with Hernando County's & FDOT’s traffic study standards and Highway Capacity Manual methodology.
Scope of Work
The engagement began with a review of the County's pre-application meeting notes and applicable traffic study standards, followed by direct coordination with Hernando County traffic review staff to obtain approval of a formal methodology statement. Third-party traffic counts were then commissioned at the study area intersections for AM and PM peak periods. Traffic signal timing was obtained directly from Hernando County for use in the signalized intersection analysis. Site-generated trip generation estimates were prepared using ITE standards, and distribution and assignment calculations were developed for each of the three site access connections and translated into a series of AutoCAD turning movement figures covering existing, adjusted, background, site, and total traffic scenarios.
The analysis phase included a roadway link evaluation using FDOT Generalized Service Volume Tables and intersection capacity analyses using Highway Capacity Software (HCS) for both the unsignalized site access connections and the adjacent signalized intersection at Mariner Boulevard and County Line Road. Results were evaluated against Hernando County level of service requirements, and the completed TIA was finalized through a comprehensive QC process and submitted to Hernando County for review.
Summary
This project reflects BCW Engineering's established workflow for transportation impact analysis — coordinating closely with the reviewing agency to deliver a thoroughly documented, peer-review-ready report. The study provided the client with a complete technical record of the development's traffic impacts and the analytical basis for any recommended improvements.
7Brew at Heron Creek Town Center
LOCATION: North Port, FL
CLIENT: Bowman Group (November 2025 - March 2026)
BCW Engineering was retained to prepare a Traffic Impact Statement (TIS) for a proposed commercial development along the Sumter Boulevard corridor in North Port, FL. The engagement began with a proactive review of the local Land Development Code that identified a potential basis for exempting the project from the full TIS requirement — an argument BCW Engineering procured City staff approval of before proceeding with an abbreviated TIS.
Scope of Work
Due diligence included a review of client-provided documents, a records request for a prior traffic study prepared for a nearby apartment development, and direct coordination with City staff regarding the LDC exemption question. Existing traffic volumes provided by City staff were adjusted for peak season using PSCF factors, and future background traffic was estimated using growth rate calculations. Trip generation, distribution, and assignment were developed for the project's access connection at Sumter Boulevard and White Ibis Drive for both AM and PM peak hours, and a full suite of AutoCAD turning movement figures were prepared to illustrate each traffic scenario.
Intersection capacity analyses were conducted using Highway Capacity Software (HCS) for the unsignalized study intersection under existing, peak season adjusted, background, and background-plus-site traffic conditions for both peak periods. Analysis inputs were initially conservative, but were subsequently refined through several iterations — including adjustments to the growth factor, pass-by trip percentages, truck percentage, peak season conversion factor, and median storage assumptions — to ensure the model accurately reflected site-specific conditions and was not overly conservative. Results were compiled into a summary table and incorporated into a comprehensive report narrative covering existing conditions, trip generation, distribution and assignment, findings, and conclusions. The report was reviewed with the client prior to submittal, updated per their feedback, and then submitted for City permitting review.
Summary
This project showcased BCW Engineering's ability to add value beyond the technical deliverable itself — identifying a potential LDC exemption at the outset and engaging the City directly before committing to the full study scope, which saved the Client both time and money. When the analysis proceeded, the result was a carefully calibrated, well-documented Traffic Impact Statement delivered on a compressed timeline and tailored to the specific operational conditions of the Sumter Boulevard corridor.
Ivy Kids Daycare at Sunlake BLVD
Location: SR 54 and Sunlake BLVD, Pasco County, FL
Client: Integrand (February 2026 - March 2026)
BCW Engineering was retained to prepare the traffic study methodology statement and access management application for a commercial outparcel development in Pasco County. The work required a thorough review of the Pasco County Land Development Code for access management and transportation analysis requirements.
Scope of Work
BCW Engineering researched Pasco County LDC requirements for access management and traffic impact analysis, and updated a previously submitted access management application form to reflect the current project scope. As part of that update, an ITE trip generation estimate was prepared using the 12th Edition Trip Generation Manual. A CADD design base was developed from parcel and plat data sourced from the SWFWMD and Pasco County, and a location map was prepared to accompany the application package. A formal methodology statement was developed in parallel, documenting the proposed study approach, analytical framework, and applicable County standards. The methodology underwent several rounds of QC before being submitted to the client for developer review and then formally transmitted to Pasco County staff.
Summary
This project reflects BCW Engineering's careful approach to the front end of the transportation permitting process — ensuring the methodology and access management application are grounded in the correct LDC requirements and submitted in proper form before any analysis work begins. A well-prepared methodology sets the foundation for a smoother review and a more defensible final study.
