History & geography

History

The original owner of the area was Banning Austin. In 1949, Austin sold the land to Glen and Betty Corning, who named it "the Ranch" and lived there with their children until in 1968 they sold 1,200 acres of property for $1.8 million.

From this point on, the SVCA held the title to all the roads, parks, greenbelt, recreation facilities, marina, airstrip, and the country club. Sudden Valley was well on its way to becoming the community it is today. Ever since its conception in the late 1960s, over 7,000 residents, plus an abundance of wildlife call it home.
