Chicago's Climate Action Plan and Our Roots Chicago plan target a 30% citywide tree canopy by 2050, paired with cool-roof mandates and reflective alley programs to cut urban heat-island intensity.
Heat-island mitigation in Chicago combines the 2009 cool-roof rule (MCC 18-13), the Green Alley Program operated by CDOT and Water Management, and the Our Roots Chicago tree-planting initiative launched in 2022. Our Roots Chicago commits to planting 75,000 trees citywide by 2027 with priority in heat-vulnerable wards identified by the Heat Vulnerability Index. The 2022 Climate Action Plan sets a 30% canopy-cover goal by 2050, up from roughly 16% baseline. The Green Alley Program installs permeable, high-albedo pavement in residential alleys. Streets and Sanitation also coordinates emergency cooling-center activation when National Weather Service heat advisories trigger.
Tree-removal violations of MCC 10-32 (parkway trees) carry replacement-cost recovery and fines of $500 to $2,500 per tree. Cool-roof noncompliance under MCC 18-13 follows the building-permit fine structure of $300 to $2,000 per violation.
