Located in the state of California and a city in Orange County, Lake Forest was previously called and known as El Toro. In 2000, the city expanded its city limits that will include the master-planned developments of Portola Hills and Foothill Ranch. With the city’s expansion, it brought new homes and commercial establishments to the city’s northeastern boundary. The “forest” which the city was also named sits in an area that is in between Ridge Route, Jeronimo, Lake Forest, and Serrano roads, and wherein most consist of Eucalyptus trees. The forest is man-made and was created in the 1900s when a local landowner planted 400 acres of eucalyptus groves within the border of Serrano Creek as a part of a lumber operation that was intended to draw development in the area.
