In 1882, a young engineer surveying the town site for Covina CA noticed how the San Gabriel Mountains formed a sort of curve or cove around the vineyards below, and suggested combining the words cove and vine to name the town Covina CA. In 1901, the city incorporated and in 1922 it adopted the slogan “One Mile Square and All There.” Citrus orchards soon blanketed the hills and the city began claiming to have the “best oranges in the world.” Today Covina CA is larger and more developed, with homes replacing the orchards.
