The document discusses quantifying the value of parks, trails, and greenspace. It notes that projects must demonstrate benefits to compete for limited funding. Case studies show that green infrastructure provides recreation, health, environmental, and economic benefits. A study of a 300-mile trail system in Houston found annual benefits of $124 million, yielding an ROI exceeding costs within 4 years. Quantifying such benefits through metrics like health savings and property values allows green projects to justify funding based on returns.
