Keeping Cool in the Capital Region

Keeping Cool in the Capital Region Capital Region Urban Heat Island Mitigation Project Capital Region Urban Heat Island Mitigation Project The Capital Region Urban Heat Island Mitigation Project, led by Sacramento Metropolitan Air Quality Management District and the Local Government Commission, built detailed models of the UHI effect in the Sacramento region and used them to evaluate the effectiveness of a range of heat mitigation measures. These findings have been translated into strategies and recommendations to minimize the UHI effect in the Capital Region, focusing on the transportation sector and communities most vulnerable to extreme heat. The Sacramento region already bears a disproportionate heat-health burden, with the number of heat-related deaths and hospital visits in the region exceeding the state average (CDPH). The transportation sector, with its miles of highways, roads, and other paved surfaces, is one of the largest contributors to the UHI effect. Extreme heat also deteriorates pavements and other transportation infrastructure, resulting in disruptions and maintenance costs for taxpayers. Average Urban Heat Index Urban heat affects each of Sacramento's neighborhoods differently. This model shows the average temperature differences seen throughout the region, using temperature averages from 2016. In places such as Northern Sacramento, Auburn, and Lincoln, temperatures are higher because of heat transport from Sacramento's urban core. Read more about the urban heat island index and what it means for your neighborhood. Electric Vehicles in the Capital Region Zero-emission vehicles, including electric vehicles, can help to reduce extreme heat by reducing waste heat that comes from conventional gas engines, thus lightening the urban heat island effect. Unfortunately, in the region, electric vehicles are likely to face heat-related impacts on battery resistance and capacity due to rising temperatures. Electric vehicle investments in the Sacramento Region are a top priority for Sacramento Metropolitan AQMD and many other local government organizations. EVs have the potential to significantly cool the region, but only if heat resilience is considered. Community Priorities Report Community engagement and outreach, particularly with disadvantaged communities, is a core part of the project. The project team gathered input from vulnerable communities on their transportation needs, concerns, and priorities, with the findings to inform all aspects of the project and serve as a resource for other planning projects.
