History
Santa Venetia is built on marshland that was filled in 1914. At that time, real estate developer Mabry McMahan envisioned a bayside luxury development modeled after Venice, Italy. Venice is known as "Venezia" in Italian; however, there is no actual Christian saint ("Santa") named Venice or Venetia. The development was designed to be complete with canals and gondolas. The economic decline following the First World War put an end to the project.

It was only after the Second World War that significant development took place in Santa Venetia, with suburban developments such as Gallinas Village being built on the land originally filled in 1914.

Santa Venetia was home to the local YMCA until it was destroyed by a fire in 1986. Eventually the property was purchased by a developer who erected residential houses that were completed in 1987.

During the 1960s and 1970s the area was known affectionately to residents, especially teenagers, as "Lower Scabo" and "Upper Scabo".

Today Santa Venetia is a quiet neighborhood with a rural feel. Residents treasure its proximity to China Camp State Park, and many homes along the canal have water access.

During this time, Dick was using methamphetamine and other drugs quite heavily, living semi-communally with a rotating group of mostly teenage drug users. His experiences during this time formed much of the basis for his novel A Scanner Darkly.
 Charles "Chuck" Riley, one of the two perpetrators of the 1975 "BBQ murders", lived in Santa Venetia up until the time of his arrest and eventual imprisonment. Riley and his girlfriend Marlene Olive murdered her adoptive parents, James and Naomi Olive, in Terra Linda and disposed of the bodies by burning them in a firepit in nearby China Camp State Park.
