This episode of “Pause for the Truth,” titled “Smart Surfaces for a Climate-Ready Future,” features Dr. Rogers Cain and Jocelyn Turner, joined by Reverend Dr. John Robinson, Dr. Jimmy Smith, and Christopher Smith. The discussion highlights the critical role of “smart surfaces” in addressing climate change impacts, particularly extreme heat and flooding, in urban environments and historically disadvantaged communities like those in Jacksonville.

Key Points:

• The Problem: Intentional Disinvestment and Disparities:

  • The guests emphasize that disparities in heat and flooding in certain neighborhoods are not accidental but are the result of historical public policy, redlining, and environmental racism.

  • Areas like Reebolt and Riverview in Jacksonville, often populated by minority residents, are built on toxic ash, lack green infrastructure, and are covered in dark, heat-absorbing, impervious surfaces. This leads to higher temperatures (10-15 degrees hotter than wealthier areas), increased flooding, and higher rates of respiratory diseases, hypertension, and lower life expectancy.

• What are Smart Surfaces?

  • Smart surfaces represent a comprehensive suite of interventions designed to transform the built environment. This involves changing horizontal surfaces (roads, sidewalks, roofs, parking lots) from dark, heat-absorbing materials to lighter, reflective, and permeable options.

  • The goal is to mitigate extreme temperatures and manage stormwater more effectively.

  • This isn’t about inventing new technology; cool pavement, cool roof materials, and water gardens (using specific plants to absorb water) already exist. The challenge lies in equitable implementation.

• Public Health and Socioeconomic Benefits:

  • Reduced Heat-Related Illnesses: Lower temperatures decrease stress on individuals with conditions like hypertension and diabetes, improving overall health.

  • Improved Air Quality: Trees and green spaces help filter air pollutants.

  • Enhanced Educational Outcomes: Cooler school environments allow children to learn more effectively.

  • Economic Benefits: Reduced utility costs due to cooler homes/offices, fewer missed workdays due to heat, and potentially lower insurance rates in less flood-prone areas.

  • Increased Property Value and Generational Wealth: Investing in green infrastructure and smart surfaces helps stabilize neighborhoods and allows properties to retain value for future generations.

  • Crime Reduction: Studies show a correlation between increased tree canopy and decreased crime rates.

• Equitable Deployment and Advocacy:

  • Ensuring equitable distribution of smart surface technologies requires policy changes at the city level. Examples include Atlanta’s “cool roof ordinance,” which mandates cool roof technology for new commercial and residential structures, with minimal cost differences (2-3 cents per square foot).

  • Cities like Baltimore, Phoenix, and Miami are also implementing similar strategies and appointing resilience/sustainability officers.

  • The panelists strongly encourage residents to become advocates, attend city council meetings, and hold elected officials accountable for investing in climate-resilient infrastructure across all communities, not just wealthier ones.

  • They highlight the need for investment in areas like Reebolt to move water away from homes and humans, potentially through solutions like pump stations seen in other parts of Jacksonville (e.g., San Marco).

  • Collaboration with local schools (including technical and two-year institutions) can provide opportunities for students to learn about and contribute to these technologies, fostering local expertise and job opportunities.

  • Organizations like the Smart Surfaces Coalition (smartersurfacescoalition.org) and LISC Jacksonville (lisc.org/jacksonville) are working at grassroots and policy levels to drive these changes.
