Extract 23 stormwater structures / 22 pipes and 18 sewer manholes / 17 pipes with sizes, inverts, ground levels and positions from the C3277 long-section tables (superseded sewer copies dropped by matching the issued PDFs). New model folder 2026-10-21. Map 3 draws them as round pipes and manholes, adds status popups for pipes and manholes, and reuses Map 2's services panel; water stays plan routes.
