Covina history:

Covina is a city in Los Angeles County, California about 22 miles (35 km) east of downtown Los Angeles. The population was 46,837 at the 2000 census.

Covina is often mistaken for West Covina which is actually larger in both area and population, located to its south and westside. Irwindale lies to the west, as well as the unincorporated area of Vincent, and the city of Baldwin Park. Azusa and Glendora are to the north, the unincorporated community of Charter Oak to the northeast, San Dimas to the east, the unincorporated area of Via Verde, and Pomona to the southeast.

The Southern Pacific Railroad, which reached Covina in 1884, and the Metrolink San Bernardino Line pass through the city just north of the downtown area.
