Overview
Alta Loma is an affluent area in
San Bernardino County
San Bernardino County ( ), officially the County of San Bernardino and sometimes abbreviated as S.B. County, is a county located in the southern portion of the U.S. state of California, and is located within the Inland Empire area. As of th ...
. It is almost completely residential and, by city ordinance, no commercial business may exist above 19th Street, with the exception of several businesses already in place when the ordinance was enacted (such as the intersection of Lemon Avenue and Haven Avenue). In addition, homes north of Banyan Street must have a minimum of 1/2 acre lots, with the exception of the development known as "Compass Rose Phase II", directly west of

(between Banyan Street and Wilson Avenue).
The three communities incorporated after years of debate and at least one failed attempt on the ballot. Residents of Alta Loma and Etiwanda finally agreed to incorporation provided their identifying community names would be kept along with separate post offices and ZIP codes. In addition, businesses are permitted to use either Alta Loma or Rancho Cucamonga on letterheads, business permits, and other records.
Alta Loma (and much of the rest of Cucamonga) was formerly home to old citrus groves and grape vineyards. The reason many homes above Banyan Street, in particular, have orange and lemon trees on their property may be attributed to this; many horse trails are lined with
eucalyptus

History
Grand Prix Fire

Rancho Cucamonga, Alta Loma and Etiwanda were most affected by the October 2003 Grand Prix fire, which combined with the
Old Fire
The Old Fire was a large complex wildfire that started on October 25, 2003 (the original Old Fire began on October 25), near Old Waterman Canyon Road and California State Route 18 in the San Bernardino Mountains, in San Bernardino County, South ...
.
The Grand Prix fire, which began October 21, 2003, ripped across the mountains just above and, in some places, down into Alta Loma and Etiwanda for six days. Overgrown brush fueled fire, which ran across the mountain tops and higher foothills to eventually fly into the canyons that are surrounded by homes. It destroyed 13 homes (including 2 mobile homes) and five outbuildings, and damaged 9 others in Alta Loma.
Geography
Most of the homes in the foothills of Alta Loma and Etiwanda sit on

Cucamonga Canyon in particular is a favorite among hikers, although dangerous due to the rough terrain, loose rocks, possible flooding, poison oak, bears, mountain lions, rattlesnakes, bobcats, and other wildlife. Far up the canyon are the
Cucamonga Falls, which have occasionally caused contention between the city council, residents, and developers, due to developers wanting to build homes over the falls.
