Assess students' ability to create a complete integrated watershed management plan for a 50 km² urbanizing basin that meets targets of 40% reduction in peak stormflow and 60% reduction in annual nutrient loads by applying green infrastructure strategies, land‑use zoning changes, and hydrologic modeling (pre‑ and post‑development); include a 20‑year cost–benefit analysis, implementation timeline, key assumptions, calculations, monitoring plan, and evaluation of trade‑offs.
