text:  The bright blue fountain stands out among the earthy tones of downtown Phoenix across the street from City Hall. It was installed in January when the average high temperature is 66 degrees. In July, it's 106. This is a very important item if you're homeless. Adrian Hopkins doesn't have permanent housing. Last year, 45% of heat-related deaths in Metro Phoenix were among unhoused people. Hopkins sometimes sleeps outdoors and starts his day at the fountain.
