Assess students' ability to analyze environmental, social, and economic trade-offs involved in converting a school parking lot into a rain garden and play space. Items will require evaluating environmental benefits (stormwater management, biodiversity, heat reduction), social impacts (play value, safety, accessibility, community use), and economic factors (installation costs, long‑term maintenance, funding options). Students should compare short‑ and long‑term outcomes, weigh stakeholder perspectives, perform simple cost–benefit reasoning or estimates, and justify a recommended design or policy choice with evidence and clear reasoning.
