## History

Highgrove was founded in 1886, originally called East Riverside, but in 1897 during a naming contest, it was renamed to Highgrove, after not getting it confused with the city of Riverside. Citrus-farm growers have occupied Highgrove area since beginning of history, with its superior fresh-wind conditions from the west, blowing into east of a cove-shape like terrain, making it one the most valuable places in the Inland Empire for citrus-farming by generations of farmers. Due to the stronger wind conditions that can easily move air out, a landfill dumping ground was opened in 1947 for discarded farm waste. Originally, it operated as a fire-burn dump during the 1950s, until 1960 when there was a concern of heavy-smog in southern California.
In 1970, the Highgrove Agricultural Preserve conservation was formed in order to support the growing number of orange trees from farmers. More diverse of citrus fruits were being grown for the packing houses in Riverside. However, farming output could only peaked by the mid-1980s. More competition on fruit prices had increased daily from new farming businesses in the Central California region. Highgrove's another biggest threat was its rising land-value and water cost for the groves by the end of 1980s, due to its close-proximity to downtown Riverside, which made farm crops more unprofitable. By 1990, the preserve contract was not renewed, citing increases of population density, housing shortage, traffic jam, university students commuting to campus, and smog near the city of Riverside. Citrus (mostly orange) trees were gradually phased out and torn down completely by the year 2000.
The Highgrove sanitary landfill closed permanently in 1998, after 51 years of operation. Since the 2018 inspection yearly report, no methane output has been detected in any of the designated area. Today, new construction homes occupy near front of it, across Pigeon Pass Road, on the former Highgrove Agricultural Preserve land. The citrus industry declined in the area as more agricultural areas were replaced by new subdivisions. In 2007, Spring Mountain Ranch master-planned community was originally conceived by RWR Homes, but construction halted due to the 2008 recession, and now KB Home, in 2014, will be completing this long-awaited project today, with no HOA fee as its main selling point. Other builders included are D.R. Horton, Lennar, and PulteGroup with some HOA fee.
Today, Highgrove is seeing a transformation with over 2,500 new single-family homes and 846 new townhomes proposed at the eastside, at the once former Highgrove Agricultural Preserve that was officially diminished by 2008. In addition, a new K-8 school or magnet high school is planned. The new housing units are currently the only ones available near the University of California, Riverside campus and downtown Riverside.
