A Scientific Plan for a Healthier, More Resilient Eastside L.A.

USC Urban Trees Initiative

The USC Urban Trees initiative partners USC experts and students with the City of Los Angeles to guide the growth of an urban forest of shade trees that benefit the health and quality of life for local communities.

The initiative focuses on a 3.5-square-mile area near USC’s Health Sciences campus. Using advanced mapping technology, air quality measurements and landscape architecture expertise, the project explores where, how many, and what type of new trees could be added to this area to optimize the benefits of urban forests.

More trees, and the shade that they offer, can improve people’s health and well-being. Trees help reduce risks such as heat stroke, heart attacks and breathing problems caused by air pollution and excessive heat. They can also increase opportunities for everyday exercise by making walking and biking more comfortable. Trees can help build communities, but it’s important to plant the right trees in the right places.

Working with local community organizations and leaders, the USC Urban Trees initiative combines scientific analysis with social priorities defined by the needs and preferences of Eastside residents.

This partnership with USC allows us to leverage world-class, multi-disciplinary scientific expertise to guide our urban forestry planning. – Rachel Malarich, L.A. City Forest Officer

How can we beat the heat?

Los Angeles is getting hotter every year. During a heat wave, temperatures can reach 140 degrees on asphalt streets and 120 degrees on typical sidewalks. Climate change is expected to make things even hotter.

Communities with fewer trees, such as those on our Eastside of L.A., are more vulnerable to heat. But trees can help. On very hot days it can be up to 50 percent cooler under a shade tree.

To address some of these environmental inequalities, L.A.’s ambitious Green New Deal includes planting 90,000 new trees citywide and increasing the forest canopy in low-income heat zones by 50% by 2028. This growing urban tree canopy will make L.A. a more livable place, with healthier residents.

The USC Urban Trees initiative will provide critical insights for how and where to plant trees to ensure maximum benefit to residents. It also presents a vision for climate justice, meaningful engagement with the people who live in the area, innovative studies of air quality and soil health, and advanced GIS analysis and mapping to identify how the Eastside can get the most out of L.A.’s tree-planting efforts.

The USC project team took care to listen to the community over the past three months. In a series of virtual meetings, they met with representatives of local non-profit groups, City Council representatives and business leaders. In the months ahead, they will meet with more residents and local business owners to gain input and help shape recommendations. If you would like to be included in these conversations, please don’t hesitate to reach out to the project coordinator at babboni@usc.edu.
