Imperial Beach is surrounded by water on three sides.
The National Oceanic and Atmospheric Administration predicts sea levels could rise by up to six and a half feet by 2100, which means drastic increases in erosion, flooding and storms for communities like I.B.
Such a rise in sea levels could eventually impact 30 percent of the city’s property, 40 percent of its roads, an elementary school, the sewer system and more.
If residents want to keep tourism, recreation and protect the environment, they would need to choose strategies that keep their beaches wide and protect them from coastal erosion.
In this week's San Diego Explained, NBC 7 San Diego's Monica Dean and Voice of San Diego's Maya Srikrishnan explain how the coastal city is bracing for sea levels rise.
