Mountain View was incorporated in 1904 on the land occupied by the Berkeley Annex subdivision established in 1888, which itself was part of the Berkeley Farm founded by John Brisben Walker in 1879.
The town grew to approximately 500 residents living in 272 houses by 2008, with approximately 20 businesses in operation, but occupying a total of only 12 square blocks "sandwiched between Wheat Ridge and Denver."
