Mesa’s next City Hall at the Mall on May 7 will focus on the iMesa initiative, which is the city’s effort to develop transformative community projects nominated by residents. The event at Fiesta Mall will have computers set up for visitors to submit ideas and vote on their favorites through the iMesa site, imesa.mesaaz.gov. Also, the city will look for residents to participate in filming an iMesa public service announcement. As with other City Hall at the Mall events, about 20 city departments will have displays and information set up. The event is scheduled from 10 a.m. to 2 p.m. May 7 in the mall’s center court.
