Coastal Flood Outfall Pump Elevation Package

Calculates source-bound coastal resilience metrics from a deterministic SSC-04 task-owned source pack. The template combines a single coastal datum and planning horizon, sinusoidal outfall submergence, design flood level, tide-locked inflow/storage/pump response, pump motor power, equipment freeboard, and pump feeder voltage drop for one compact generated task instance.

with-tool: The model is given an executable Python calculator script.
