Los Angeles County Service
Planning Area 3-San Gabriel-is one of the largest County
geographic regions in terms of land area, second only to the
Antelope Valley (SPA 1). SPA 3 is situated between the San
Gabriel Mountains to the north and the Whittier Hills to the
south. The foothills are dotted with a number of independent
cities such as Glendora, Sierra Madre, San Dimas, La Verne,
and Claremont. The SPA’s western border is defined by the
western boundaries of the cities of Pasadena, South Pasadena,
Alhambra, and Monterey Park. Its eastern boundary is the San
Bernardino County line, contiguous with the city boundaries of
Claremont, Pomona, and Diamond Bar. SPA 3’s southern border
runs below a series of unincorporated areas (the Whittier
Narrows Recreation Area, Hacienda Heights, Rowland Heights)
and the Orange County line. |
