Small-Town Stormwater Planner: Rational Method Peak Flow, Pipe Capacity and Street Ponding (3D)

Repaint a 24 by 16 tile town of roofs, roads, lawns and trees, pick a design storm and watch the rational method Q = C i A, Manning pipe capacity and street ponding decide where the water goes; swap in green roofs and permeable paving to cut the peak.
