Los Angeles has over 900 of miles of alleys that are often used for dumping and experience high instances of crime. The Trust for Public Land Climate Smart Cities program is a national program for assisting cities in projects to mitigate and adapt to climate change. The Avalon Green Alley Demonstration project repurposed a mile of underutilized alleyways in South Los Angeles into green alleys.

The Trust for Public Land Climate Smart Cities collaborated with the City of Los Angeles, UCLA, and Arizona State University to create green alleys in South Los Angeles. These green alleys improve air quality and contribute to urban cooling, mitigating extreme temperatures and the urban heat island effect.

The green alley also helps to filter pollutants from stormwater runoff and control stormwater, mitigating flooding and recharging the groundwater. Additionally, the repurposed alleyways provide recreational space and improve the walkability and bikeability of the area. The green alley creates a safe passageway between various key destinations in the area, including a grocery store and nearby schools. The safe passageway improves community connectivity.

A volunteer group, Equipo Verde (Green Team), manages the green alley, organizing volunteer days, picking up garbage, and landscaping and planting trees. The group improves community engagement and educates the local community on the importance of managing these alleyways.
