Implementation
Collaborate with the Capital Region Climate Readiness Collaborative (CRCRC); the California Environmental Protection Agency; the University of California, Davis Pavement Research Center; and other regional partners to obtain guidance, explore pilot projects, or obtain other technical support to identify and determine cool pavement technologies best suited for different applications in the County. Following this effort:
Develop and incorporate cool pavement standards into the County’s roadway design manual for use in public rights-of-way. These cool pavement standards would apply to construction or modification of County-owned facilities and may vary based on location.
Develop and incorporate cool pavement standards into the County’s development standards for private development projects. These cool pavement standards would apply to both new construction and changes to existing on-site paved surface areas (e.g., parking lots, private roadways, bike trails and sidewalks, or other hardscape areas) and may vary based on location.
Support implementation of actions under Measure Temp-08. (Note: This action could also be achieved collaboratively with others as part of the regional UHIE initiative described earlier under Measure Temp-02.)
Benefits: Incorporation of cool pavements into maintenance of existing and construction of new paved surfaces would lower the amount of heat absorbed compared to traditional paving materials. Cool pavements reduce the effects of UHIE by reflecting sunlight and absorbing less heat as compared to traditional pavement. Implementation of cool pavements would lessen the impacts of UHIE, which would result in reduced exposure to heat-related illness, decreased building energy consumption and associated GHG emissions, and improved air quality. Pavement reflectance can be enhanced using reflective aggregate, reflective or clear cinder, or a reflective surface coating.[1]
Co-benefit
This measure will support measures related to flood risk and support GHG reduction measures GHG-02, GHG-04, and GHG-05.
