According to Wiki, USS Richmond:
In January 1925, Richmond, flagship of Light Cruiser Divisions, Scouting Fleet, again participated in Caribbean exercises. In February, she transited the Panama Canal and during March trained off the California coast. In April, she steamed to Hawaii for joint Army-Navy maneuvers, after which she joined the Battle Fleet for a good will cruise to Australia and New Zealand.
For the misdirect then - not in the US, so either the Panama canal area, Australia or New Zealand?
Possibly Point Cook - if what I thought was a slipway is a jetty/pier (bloody long one), the buildings seem to match up.
