[Assess students' ability to create a complete, practical design for a climate‑resilient 50 m² urban rooftop garden in a temperate coastal city that maximizes biodiversity, edible yield, stormwater retention, and passive cooling while keeping materials and installation under $2,500. Deliverables must include a scaled layout plan, plant selection list with ecological and edible-ratio rationale, soil/media specifications and depths, an irrigation strategy (water source, water-saving measures, estimated water budget), stormwater retention/overflow details, passive cooling measures, a seasonal maintenance schedule, an itemized cost breakdown, and a brief justification of assumptions and measurable performance targets.]
