City of Lake Forest

Parks, sports fields, and trail connections thread through the city, while business parks along the 5 and 241 corridors host tech, manufacturing, and logistics firms. The Foothill Ranch and Portola Hills areas add newer housing and retail.

Incorporated in 1991 from the communities of El Toro, Foothill Ranch, and Portola Hills, the city’s name reflects two man‑made lakes and the surrounding eucalyptus groves originally planted as a 20th‑century windbreak.
