How this is counted

The five-column module groups only records with a safe PlanningBrief project match. Attached means notices present in this weekly snapshot. Because the snapshot has no populated overall scheme-unit field and notice or phase values can repeat, the displayed project value is the largest supported attached value and is never added across notices. Every notice remains in the records list with its separate stated commencement date. This page reads the frozen weekly snapshot for 17–23 Aug 2026 and performs no visitor-time fetch.
