SAN FRANCISCO (KPIX) – In what sounds like an instance of NASA-level spending, the city of San Francisco is budgeting $1.7m for a single public toilet in the Noe Valley neighborhood.Finding a public bathroom in many parts of San Francisco can be challenging, particularly in the busy area around Noe and 24th.Known for its boutiques and quiet tree-lined streets, the town square on 24th Street has become something of a neighborhood hub. Home to an ever-popular weekly farmers market, the square is a popular meeting spot for local families and neighborhood dwellers.Richard Andronaco likes to spend his days on one of the public benches doing a crossword puzzle.Absent from the square is a public restroom.
