The neighborhood is mainly residential, with a small commercial section along Gilman from Santa Fe to Tevlin Street.
The elevated tracks of the BART Richmond line cut diagonally across Westbrae, crossing over Gilman in the commercial section.
The Key System was part of a larger enterprise which included real estate, the Realty Syndicate.
The name "Westbrae" was given by the Key developers and included tracts north of Codornices Creek in Albany.
There were future plans to extend the G-Westbrae line northward to serve the development area, but this never happened.
