With cool pavement and cool roofs installed in the region, we can reflect 20-60% of solar energy back into space, thereby cooling the area. Trees and shade cover can also bring surface temperatures down by up to 40 degrees. Tools like Treeviewer show how much tree coverage West Valley/Hollywood area has, as well as the potential for new trees. Currently, parts of West Valley/Hollywood have up to 6% to 8% less tree coverage than the county average, showing that there is a lot of potential for new trees to cool the area and advance equity. By taking these steps, West Valley/Hollywood will be better prepared for extreme heat days.
Through urban greening, air quality monitoring, and reducing pollution, the West Valley/Hollywood region can transform its air quality. Tree canopy and ground-level vegetation absorb and disperse pollutants, and they can reduce heat at the same time. An air quality monitoring plan will keep track of the amount of pollutants in the region and allow people to take precautions like using pollution masks or avoiding outdoor activities. Lastly, by improving the accessibility of active and public transportation, we can address both air quality issues but also heat issues. For example, bus shelters can reduce heat and encourage bus ridership, thus addressing heat and air quality issues at the same time. Overall, these methods can lower the amount of cars and the pollutants produced from them, thereby improving air quality in West Valley/Hollywood.
We can improve storm-water capture basins and systems in the San Fernando Valley, aggressively use unused pieces of land in Los Angeles for storm-water capture, and modify current dam and flood control basins to improve water conservation. With these methods, West Valley/Hollywood will be able to capture water better during periods of extreme precipitation and can save it for periods of drought.
