Beaufort County emergency management chief urges planners to "think of the ripples" of road projects, points to high-crash Sea Island Parkway

Colonel Neil Baxley, Beaufort County's emergency management director, told the county's Transportation Advisory Committee that some roadway projects have improved one local safety problem while creating traffic and safety "ripples" elsewhere.

"I want to ask you that as you go through this process, think not only of the immediate area that you might be looking at, but think of the ripples," Baxley said. He pointed to the Boundary Street project as an example where a planned frontage road was never built, concentrating traffic on a single corridor.

Baxley outlined several specific problem corridors. He said the two-mile Sea Island Parkway stretch downtown has had "nearly 5,000 accidents" since 2018, including three fatalities, and described daily school-access congestion where planned access points were not built as intended. He also noted that in 2025 the sheriff's office investigated 2,033 motor-vehicle accidents and issued 6,574 uniform traffic tickets plus 8,848 warnings — figures he cited to underline the scale of local enforcement and education needs.

Baxley argued that common design features ' short storage lanes, inadequate "elephant ear" u-turn cutouts, mismatched lane transitions and incomplete frontage roads ' can exacerbate crashes and congestion at downstream merges such as Callawassee and around Moss Creek and Simmonsville. "Good idea, bad implementation," he said of some countermeasures.

He also warned that current evacuation capacity is limited: staff studies cited by Baxley estimated it would take more than a day to move everybody who would want to evacuate in a major storm. He said meaningful hurricane-evacuation improvements will require capacity West of Beaufort County and coordination with regional facilities.

In questions, committee members pressed Baxley on specific locations and countermeasures including R-cut ("elephant ear") turn facilities, roundabout conversions, and adaptive signal timing. Baxley and staff said some techniques can work in the right locations but must be evaluated with diagrams and traffic modeling; they agreed to provide bullet-point summaries and diagrams to the committee.

Why it matters: Baxley's presentation framed traffic engineering not as isolated fixes but as system design: adding lanes or changing intersection form can shift congestion and safety risks to other locations. That framing informs the committee's decision to size and prioritize projects for a possible transportation sales tax.

Next steps: Baxley said he would provide written bullet points and staff will include his recommended hot-spot considerations in the committee's master project list and modeling materials so the group can compare safety improvements against cost and schedule.
