Highlights

Maricopa County and Clear Channel Outdoor are renewing a heat relief billboard campaign that the county says has reached tens of millions of residents during critical summer months, with the effort returning this month as temperatures rise.

The campaign directs residents to 211 Arizona, which connects callers to more than 230 local heat relief sites across the county, according to a prior county announcement. Clear Channel Outdoor's regional digital billboard network provides concentrated coverage throughout Maricopa County, which represents approximately 62% of Arizona's population, per the company's Phoenix market page.

The partnership first launched in June 2024, when the county and Clear Channel Outdoor announced a regional digital billboard campaign to share heat relief resources and real-time information with residents and visitors, according to a PR Newswire release. The county is home to more than 4.5 million people, the county previously noted.

The renewed campaign is active now.
