TheVoiceOfJoyce For years Los Angeles has implemented reflective asphalt and roofs that are painted to reflect the sun’s rays. The Hispanic neighborhoods are hardest hit with heat deserts. The new reflective asphalt, lowers the ground temperatures 25 degrees Fahrenheit and the air temperatures 1 degrees Celsius. The new paint is used on Hospital roofs effectively. Meanwhile, to avoid 25 consecutive days of 95 degree Fahrenheit, millions of square miles are car lanes are using reflective asphalt with a life of 20-30 yrs. All cities should be adapting this methodology and more to prevent severe heat and deaths.

Los Angeles has the worst “urban heat island effect” – a phenomenon in which cities trap and retain heat due to their high concentration of buildings, roads and other developments – of any city in California. And the burden of extreme heat often falls unequally on the populace – a recent county assessment found that Latinos comprise 50% of Los Angeles’ population, but make up 67% of the population in communities with high vulnerability to extreme heat.

Design changes that could help the city absorb less heat are under way. These include installing cool roofs, coating streets with reflective materials (known as “cool pavement”) and increasing shade by planting more trees.
