Among environmental hazards, extreme heat is a particularly quiet but deadly hazard that affects large populations and, inequitably, the most vulnerable of that population. In seeking to improve the City of Los Angeles’ outlook for the future, efforts have been made within the municipal government to reduce its impact on the local climate. The city has already begun working toward these goals, with high albedo coatings being applied to city streets in 2018. However, it is infeasible for the city to try and paint the whole city or plant trees on every corner. Therefore, this research seeks to understand how targeted implementations of heat mitigation strategies can improve the thermal environment of lower income and elderly populations across the LA Basin. Using ENVI-met 4, we selected three cities (Long Beach, Pomona, and Van Nuys) to simulate conditions from summer 2018 in lower-income neighborhoods to understand what targeted heat mitigation strategies may do to improve the thermal environment of the neighborhood. The output is analyzed against in situ measurements to increase the robustness of results.
