Cool Pavements: Taking Action

Implementation resources

When considering cool pavements for your city or community, the following tools can simplify the decision-making process. The below materials serve as additional resources to demonstrate the range of cool pavement solutions that can be implemented where you live, as well as the policy guidance to lock in the maximum benefit for your area.

Cool pavement case studies

Cool pavements are now being introduced throughout California in various contexts. Cities are looking to incorporate cool pavements as climate adaptation planning measures, and school districts are trying to cool their schoolyards by using more reflective outdoor surfaces. Learn how some California entities are approaching the adoption of cool pavements in the following case studies.

Cool pavements as a climate adaptation measure

California cities are taking measures to prepare for a changing climate by developing climate adaptation plans. A recent example of this planning comes from Chula Vista, CA, where planning efforts have explored measures to mitigate high urban air temperatures that lead to high demand for building air conditioning. Chula Vista initially identified eleven climate adaptation strategies that could mitigate heat islands, decrease energy demand, and improve air and water quality. The city then drafted an implementation plan for each of its identified adaptation strategies, including cool pavements.

The implementation plan for cool pavements spans a two-year exploratory project to learn more about the local prospects for cool pavements. The ultimate goal of the cool pavements implementation plan is to develop a new municipal policy that incorporates cool paving materials into new street and parking lot projects. The city commissioned a comprehensive cool pavements study to evaluate and test multiple technologies, taking into account the costs, benefits, drawbacks, performance, and incentive opportunities for each technology.

Chula Vista’s Cool Pavements Study identifies several technologies that offer high urban heat island reduction potential, such as light-colored cement concrete products and cool pavement coatings, as well as possible funding sources for a new pavements program. The study sets forth criteria for suitable cool pavement pilot sites and for performance monitoring of the pilots to assess solar reflectance, thermal emittance, durability, stormwater effects, and noise over time. The results of this pilot program will inform Chula Vista’s guidelines for new paving as well as for pavement maintenance within five years from the study’s date of publication.[1]
