Īccording to the United States Census Bureau, the CDP has a total area of 98.7 square miles (256 km 2), all land. An exhibit of a smaller California Grizzly bear is on display at the Valley Center History Museum. The name was subsequently changed to Valley in 1874, to Valley Centre in 1878 and, finally, to Valley Center in 1887.
The notoriety surrounding the event gave Valley Center its original name of Bear Valley. Although the area had been settled in 1845 and homesteaded in 1862 after President Abraham Lincoln signed the Homestead Act of 1862, it had no formal name until the famous 1866 bear incident. In 1866, a grizzly weighing 2,200 pounds was killed at the Lovette house, which has now been demolished. Valley Center was the site of the capture of the largest California Grizzly Bear in history. The population was 9,277 at the 2010 census. Valley Center is a census-designated place (CDP) in northern San Diego County, California.
