New York City, NY

AARP Community Challenge Grant Year: 2024

Project Category: Public place improvements to withstand extreme weather events

Description: Older adults in heat-vulnerable NYC neighborhoods faced isolation and health risks during extreme summer heat, with few safe outdoor spaces. Street Lab created OASIS, a pop-up cooling station with shade, seating and a misting "river," deploying it 33 times across 15 streets. The setup also included plant carts and emergency preparedness materials, offering immediate relief and a place to connect. The project drew 1,650 people-half age 50-plus-and informed plans to scale citywide. One older adult said she loved staying cool while watching her granddaughter play in the mist, showing how OASIS turned hot streets into welcoming community spaces.

Salt Lake City, UT

AARP Community Challenge Grant Year: 2023

Project Category: Public place improvements to withstand extreme weather events

Description: Poor air quality along Utah's Wasatch Front shortens life expectancy, especially for older adults, and limited tree cover worsens heat islands. To combat this, TreeUtah organized more than 100 planting events statewide, engaging over 3,000 volunteers-including many age 50-plus-to plant thousands of trees. Two events in South Salt Lake added 20 large trees near a local facility for older adulits and included a tree care workshop. These efforts improve air quality, create shaded spaces and foster intergenerational engagement. One participant noted, "There was definitely something for everyone at this event... even my teenager had fun."

Columbus, OH

AARP Community Challenge Grant Year: 2020

Project Category: Public place improvements to withstand extreme weather events

Description: To reduce the urban heat island effect, Friends of the lower Olentangy Watershed planted large canopy trees at an elementary school playground and near a housing complex. The area has traditionally lacked tree cover, with the nearby properties having the least canopy cover of any residential area in the local watershed. The new trees increased the local canopy from 7 percent to 22 percent -- the average for Columbus as a whole. Volunteers -- including local Scouts -- helped plant the trees. In addition, project organizers installed benches at the playground to provide a respite to teachers, children and families using the playground equipment.
