The seventy-five wards are grouped by service tier so distribution crews can plan water, food, transit, and repair capacity across a changing floodplain. A tier records infrastructure demand; it is not a judgment on the residents who live there.

Ward offices submit maintenance forecasts through the civic shell, which converts local requests into a citywide order of work. The Board reviews that order against network capacity and public safety obligations.

A clear ledger prevents duplicate claims and keeps emergency stock available for certified need.
