Sioux Falls, SD
AARP Community Challenge Grant Year: 2020
Project Category: Roadway/sidewalks/crosswalk improvement
Description: The City of Sioux Falls hoped to encourage residents to consider active transportation -- walking and biking -- as a way to get around. To do this, the City created a quick-build infrastructure kit, which it used to install a temporary protected bike lane at one location and a curb bump-out at another. The bump out -- a safe extension of the sidewalk into the street -- makes pedestrians more visible to drivers and shortens the distance needed to cross the street. City planners gathered feedback from cyclists in the community, who suggested possible future locations for protected bike lanes. Because the infrastructure kit is mobile, the City hopes to deploy it elsewhere in the future.
Kapolei and 'Ewa, HI
AARP Community Challenge Grant Year: 2020
Project Category: Roadway/sidewalks/crosswalk improvement
Description: New curb extensions on Kopolei's Papipi Road not only help local children safely navigate their route to school, they also remind passersby of their rich Hawaiian history and culture. Over the past five years, daily traffic on the road increased 50 percent, with many drivers exceeding the posted speed limit. To calm traffic, Hawaii's Blue Zones Project installed bulb outs at an intersection, which safely extend the sidewalk into the street. This shortens the street crossing distance for pedestrians and makes them more visible to drivers. To make the curb extensions even more noticeable, volunteers used paint to depict limu in shades of gold and green on the pavement. Limu are edible, underwater plants -- a vital component of Hawaiian cuisine and ceremonies for generations.
Sioux Falls, SD
AARP Community Challenge Grant Year: 2019
Project Category: Roadway/sidewalks/crosswalk improvement
Description: This demonstration project had the goal of calming traffic and improving the streetscape for pedestrians. Downtown Sioux Falls used paint to create temporary bumpouts -- or curb extensions -- at a local crosswalk, which shortened the distance pedestrians spent in the street. They also used large planters to create a physical barrier between pedestrians and cars and added reflective delineators to make crosswalks more visible at night. A camera installed onsite helped capture data about traffic and pedestrian behavior during the pop-up project. The result: Drivers actually slowed down said Joe Batcheller, the organization's president. The project helped reduce speeds by 20 percent on average. Project organizers say the demonstration sparked a cultural shift around pedestrian safety. Since the pop-up, the City has painted curb bumpouts in other locations.

Bozeman, MT
AARP Community Challenge Grant Year: 2026
Project Category: Engaging residents in vibrant public places
Description: A mobile “listening bench” will rotate among parks, libraries and gathering spots for older adults. Trained volunteers will host scheduled bench hours to offer conversation and companionship, with QR codes linking users to local resources, to help reduce social isolation among adults age 50 and older.
Bozeman, MT
AARP Community Challenge Grant Year: 2025
Project Category: Park enhancements
Description: Gallatin Valley Land Trust addressed barriers that limited outdoor access for older adults and people with mobility challenges. Poorly maintained trails and a narrow bridge reduced safe use with adaptive devices. The project built a widened gravel trail and replaced the bridge with an accessible crossing. Planning advanced for accessible parking and clear trail signage through partnerships with local health and disability groups. The improvements expanded who can safely use the trails and support long-term inclusive outdoor access.
