📣 Phone-Tree Coverage

Coverage = fan-out^levels. Delivery time ≈ levels × average reply.

💧 Shared-Pump Capacity

Compare result to pump curves at your lift height.

There’s no single blueprint for every block, and local codes and terrain differ. Use the modules that fit your street, test them on a calm day, and keep notes so each round takes fewer people and less time while still reducing flood losses.
