The Alpine plan area covers 108 square miles situated in the foothills of the Cuyamaca Mountains. The area is rugged and diverse, ranging from densely vegetated lower drainageways of 1500' elevation, to semi-arid hilly terrain, to the peaks of Viejas and El Cajon Mountains with elevations of over 4100'. Interstate 8 bisects the community. Suburbanized Lakeside is the western neighbor, with the eastern limits of the area situated as a gateway to San Diego County's wilderness areas of mountains, forests, and deserts. Most of the population of 8,200 is clustered around the small town of Alpine. The plan also encompasses the Viejas Indian Reservation and small settlements in Peutz Valley, Japatul Valley, Hidden Glen, Dunbar Lane, and Galloway Valley. Existing development has a rural character typified by light agricultural activities practiced in conjunction with residential uses.
