Cities for Smart Surfaces Project: Transforming Urban Environments
Urbanization has replaced green spaces with heat-trapping asphalt and dark rooftops.
With significantly higher temperatures, these "urban heat islands" pose a major public health threat, disproportionately impacting vulnerable populations and communities of color who often lack access to green spaces and infrastructure upgrades.
APHA is excited to partner with the Smart Surfaces Coalition on the Cities for Smart Surfaces project, along with the National League of Cities, Metropolitan AME, American Lung Association and many others. 
This groundbreaking project brings together six APHA affiliates from across the country to explore the potential of smart surfaces to improve public health in urban environments.
What are smart surfaces?
Smart surfaces are transformative technologies to help cities withstand the health effects of climate change.
For example:
- Reflective (cool) roofs and pavements help cool cities by reflecting sunlight, reducing the urban heat island effect.
- Green roofs covered with vegetation provide insulation, absorb rainwater and enhance air quality.
- Trees, forming urban forests, play a crucial role in cooling and improving overall well-being.
- Solar photovoltaics, or solar panels, generate clean energy while reducing heat absorption.
- Rain gardens manage stormwater, prevent flooding and enhance biodiversity.
Why do smart surfaces matter?
Smart surfaces build climate resilience and improve public health by:
- Mitigating extreme heat. As global temperatures rise, cities face more frequent and intense heat waves. Smart surfaces like reflective roofs and green spaces help cool urban areas, reducing the risk of heat-related illnesses.
- Preventing flooding. Intense rainfall events lead to urban flooding. Smart surfaces like rain gardens and permeable pavements manage stormwater effectively, preventing floods and safeguarding communities.
- Reducing heat-related illnesses. Extreme heat poses a significant health risk, especially for vulnerable populations. Smart surfaces mitigate heat island effects, making cities healthier and more livable.
- Improving air quality. Trees, green roofs and reflective pavements improve air quality by absorbing pollutants and reducing emissions. Cleaner air translates to better respiratory health for residents.
- Boosting mental well-being. Access to green spaces and aesthetically pleasing environments positively impacts mental health. Smart surfaces enhance urban aesthetics, promoting well-being.
Our Approach
We’re proud to collaborate with six APHA affiliates by providing grants and training to raise awareness about smart surfaces’ benefits, influence local policies and planning, and drive regional smart surface projects:
- Florida Public Health Association:
The Florida Public Health Association aims to tackle heat and flooding challenges in Jacksonville through focus groups, city initiatives, and public outreach, to increase awareness and drive action on extreme heat issues. FPHA has advanced its Smart Surfaces work through statewide community focus groups, regional partnerships, and cross-sector collaboration with organizations like LISC. FPHA has integrated Smart Surfaces into student-led capstone projects, engaged urban planners and clinicians in the conversation, and contributed to building a more climate-resilient and equitable Florida. This work has strengthened the state’s capacity to respond to extreme heat and inspired continued public health leadership in infrastructure planning. - Georgia Public Health Association:
The Georgia Public Health Association is focused on increasing awareness on extreme heat and flooding issues in metro-Atlanta. Through this coalition, GPHA has created partnerships with Georgia Clinicians for Climate Action to bridge the gap between clinical providers and public health on extreme heat health issues, as well as the Morehouse School of Medicine to host community-level climate education courses on their campus. - Louisiana Public Health Association:
The Louisiana Public Health Association is focused on building partnerships, engaging communities, and promoting public health messaging to guide city-wide climate policy. Their goal is to create a cooler, safer, and more resilient New Orleans. LPHA partners with Healthy Community Services to promote incorporation of sustainable infrastructure to New Orleans. This year, LPHA has conducted research through focus groups and reviewed state legislation for gaps in climate policy. The data from these focus groups are driving the trainings and projects that are being planned, such as a Smart Surfaces Workshop and Resource Fair and continued training for staff and partners on heat awareness and smart surfaces. - North Carolina Public Health Association:
The North Carolina Public Health Association works closely with the City of Charlotte to expand awareness on extreme heat, engage with community members, and broaden a network of partners working to advance climate mitigation solutions. In partnership with CleanAIRE NC, NCPHA is conducting focus groups to hear from local healthcare providers and community members about their experiences with extreme heat. The findings will be presented at NCPHA's Fall Educational Conference and will be used to inform future advocacy efforts and implementation of Smart Surfaces. Lastly, using their experience partnering with the City of Charlotte, they will develop a resource guide for other local health departments interested in partnering with city and county governments to promote the health benefits of Smart Surfaces and other climate-related actions. - Oregon Public Health Association:
The Oregon Public Health Association is dedicated to building strong partnerships and community connections to advance climate resilience, focusing on practical tools, education, and engagement to protect vulnerable populations from the health impacts of extreme heat. OPHA is working closely with Verde, an environmental justice nonprofit, and CAPA Strategies, a national climate data and mapping firm, to develop the Living Cully Heat Resilience Resource Guide. This guide will provide multilingual, culturally relevant information and local resources for Portland’s Cully neighborhood, one of the city’s most heat-impacted areas and will be distributed at Cully Fest, where OPHA and partners will also host interactive activities to raise awareness and promote heat safety. - South Carolina Public Health Association:
The South Carolina Public Health Association’s vision for the Smart Surfaces project is to facilitate a cooler Columbia, which has an immense temperature disparity. Expected long-term outcomes of SCPHA’s work include more greenspace in Columbia, beneficial local planning and zoning changes, a more informed citizenry, and expanded Smart Surfaces partnerships. SCPHA signed a letter of support for the new OSHA standard, which aims to protect 36 million workers from heat hazards. SCPHA also launched a Mini-Grant Program to empower local organizations and neighborhoods in Columbia, SC, to implement nature-based solutions. Additionally, SCPHA engaged the community during Climate Action Resilience Week with a Tree-Planting Event, where students planted oak trees in Martin Luther King Jr. Park.
Our commitment to health equity is ingrained throughout the project. Through this lens, we assess how smart surface projects impact different communities, ensuring no one is left behind. Our Affiliates also focus on community engagement as they involve residents, especially those in underserved areas, to co-create solutions.
