Commissioners press for technical data after WSP progress report on countywide transportation master plan

Consultants from WSP updated the Palm Beach County Board on progress for the countywide transportation master plan, describing public polling, Google sentiment analysis and early modeling work aimed at understanding conditions through 2050.

Mariah Deagle, deputy project manager for WSP, said consultants gathered about 1,500 surveys, ran sentiment analysis and are conducting corridor and subarea analyses to identify pinch points and prioritize projects. She described a modeling effort that uses population and employment projections and said the project team is aiming for a June adoption milestone.

Several commissioners pushed back on the presentation's emphasis on sentiment slides and asked for more technical detail. Commissioner Flores urged the project team to show travel‑time metrics, accident data, wait times and maps of hotspot corridors rather than summary sentiment scores. Commissioner Marino warned that if the model omits planned density changes, it risks underestimating future congestion; he said, "If you're not including what could possibly happen in the future, we're already behind the 8 ball." Commissioner Weiss and others expressed concern that the schedule is compressed and encouraged staff to bring more detailed technical briefings to an upcoming meeting.

Project manager Claudia Blotto (on the line) and Ms. Deagle said detailed existing‑condition data, corridor histories and technical inputs have been developed and were reviewed by the technical IPARK group; they committed to returning with maps, modeling inputs and a focused staff briefing so commissioners can evaluate hotspots and proposed solutions (signal timing, multimodal investments, transit infrastructure) before any final adoption.

Policy questions: Commissioners also asked whether the board should pursue a dedicated funding measure (surtax) in 2026; several commissioners signaled that a surtax is unlikely this year and that the board should first review the detailed technical work and corridor priorities.

Next steps: Staff agreed to present more granular modeling results and corridor maps at a follow‑up meeting and to coordinate with commissioners on timing. The consultant noted a June adoption target but the board asked for at least one interim technical briefing with the data that underpins the plan.
