Temecula: Wine Country With a Wildfire Problem
Temecula's vineyards and valley views sit between the Santa Rosa Plateau and chaparral-covered foothills where Santa Ana winds turn grassland fire into neighborhood emergencies. The WUI is closer than you think.
Temecula is a city of roughly 110,000 in southwestern Riverside County, known for its wine country, Old Town district, and rapid residential growth over the past two decades. The Temecula Valley occupies a broad basin flanked by the Temecula Creek corridor to the south, the Santa Rosa Plateau to the west, and chaparral-covered foothills of the Palomar and Santa Ana mountain ranges to the east and north. This geography — a developed valley surrounded by wildland fuel — defines the city's fire risk.
The wildland-urban interface in Temecula is extensive and growing. As residential development has pushed into the hillsides east of I-15 and south along Temecula Creek, more homes sit within direct reach of grassland and chaparral that burns readily during the hot, dry months. The Santa Rosa Plateau Ecological Reserve's 9,000 acres of native grassland and coastal sage scrub border the city to the southwest. To the east, undeveloped foothills stretch toward the Vail Lake area with continuous chaparral cover. When Santa Ana winds descend from the northeast through the Temecula Gap — the break in the mountains that the city sits within — they accelerate to damaging speeds and can push fire across the valley floor in hours.
