The Hollywood Riviera is a bit like an obtuse “triangle.”  It is surrounded by the ocean on one side, Valmonte – a great Palos Verdes Estates neighborhood, and South Redondo Beach on the other.  The eastern tip is located in South Torrance (the whole neighborhood is in South Torrance technically.)  It is a really cool area that many people don’t even know exists – even people in the “beach cities” – this is what we summarize Redondo, Hermosa and Manhattan Beach as. 
Hollywood Riviera has an interesting feature – it has 2 addresses; Torrance & Redondo Beach.  The entire Hollywood Riviera is in the city of Torrance (South Torrance – 90505) but part of the Riviera has a Redondo Beach P.O. Box (90277.)  See the map to figure out which is where.
