Pretty sure nobody is interested any longer, but I managed to find this in my search for other shipwrecks along the Sothern California coast.
Its from the CA State Lands Commission from 1968 authorizing the search permit for Wilfred S. Takasoto to search for the Trinidad.
May I just say that I don't really believe in the story of the Trinidad, the history simply doesn't back it up, but that's not to say there may not be a wreck in the area as I also found this:

The Santo Domingo is reportedly in the same area and supposedly went down in 1540. My main problem is finding documents that reference ANY of these wrecks. The San Pedro is the only one I've traced down and know for a fact existed. The rest of these I just can't find any documentation on.
