Advisory board narrows public summary to four graphics, orders ZIP‑level data scrub

Advisory board members and staff on Nov. 6 reviewed a Power BI‑generated report summarizing complaints and blast (peak particle velocity, PPV) readings from the Miami‑Dade pilot program and directed staff to produce a simplified, single‑page public cover and a set of more detailed internal pages.
