National City is a disadvantaged community located 5 miles south of downtown San Diego and 10 miles north of the Mexican border. Pollutants from major freeways, industrial businesses, a port, and a military base negatively impact the air and water quality in the region. The emissions generated from these industrial facilities can increase rates of obesity, diabetes, asthma, and other serious health conditions. According to the statewide pollution screening tool, CalEnviroscreen, National City currently ranks among the top 5-10% of communities in California impacted by pollution. Local elected officials are hoping to change that with new policies and plans addressing housing and transportation options in the city.
