Antelope is in Sacramento County, California located approximately 15 miles northeast of downtown Sacramento and 5 miles southwest of Roseville. The population was 45,770 at the 2010 census.
In the late 1800s, Antelope was the only significant settlement in the Center Township, an area bounded on the North by the Placer county line, on the East by what is now Sunrise Blvd., on the South by the American River, and on the West by the line along 20th St in Rio Linda south to Ethan Way in the Arden-Arcade area. The population of the entire township in 1880 was about 400 people. Many of the railroad workers made their homes here and eventually stayed permanently. Gradually, workers left the area and Antelope became just another small community with little business.
On April 28, 1973, Antelope consisted of a post office, general store and a half-dozen homes – a place hardly worthy of notice. However, at 8:03 a.m., a rail car loaded with aircraft bombs exploded in the southern part of the Central Pacific Roseville switch yard destroying the general store and damaging most of the homes. This event changed Antelope forever – it basically was blown away.
What is known as Antelope today mostly began as a planned community in the late 1980s. It consisted of mainly single-family homes and apartments. Due to the relative newness of the community, most homes are new and the area is well planned out. Antelope received its own postmark and recognition as a community by the U.S. Postal Service on 1 July 1994.
