A city park is all concrete with no trees: it is $95^\circ$F, but a nearby tree park is $85^\circ$F, and flooding happens after rain. Solutions: (A) Plant 50 trees—cuts heat $8$–$10^\circ$F, helps 20+ bird species, reduces flooding, costs $\$25{,}000$, takes 3–5 years; (B) Metal shade roofs—cuts $5^\circ$F, costs $$15{,}000$, no bird or flood help; (C) Paint concrete white—cuts $3^\circ$F, costs $\$5{,}000$, no bird or flood help, repaint every 2 years; (D) Remove some concrete + plant trees + native gardens + rain gardens—cuts $10^\circ$F, helps 30+ species, absorbs rain, costs $$30{,}000$. Based on the evidence provided, which solution best addresses heat, flooding, and wildlife?
