Office of Heat Response and Mitigation Home

Phoenix’s Office of Heat Response and Mitigation (OHRM or HeatReadyPHX) is leading the efforts of the hottest large city in the United States to fight the growing hazard of urban heat. OHRM focuses on heat response (helping people cope with hot weather) and heat mitigation (cooling the city and making it more comfortable).

Throughout the year, HeatReadyPHX coordinates programs and policies to help lower urban temperatures and protect public health. It also tracks trends, collects data, and collaborates with other governments and organizations to share ideas and solutions for dealing with heat.

Get Involved! Grant Funds are Available to add more trees and shade in Phoenix. We are looking to fund projects in neighborhoods with low tree and shade coverage throughout the City.

As part of the American Rescue Plan Act (ARPA), the City of Phoenix is offering two grant opportunities to increase tree and shade coverage in Phoenix. The grant programs are: Community Canopy and Canopy for Kids.
