Narrative:
We crossed snake at 3700 ft which is 400 ft above the published crossing altitude. All other crossing restrs on the eastside arrival are at or above but snake restr is a hard altitude. After reading the arrival apparently I was set up into thinking all crossing restrs were at or above. May I suggest that all xings be at a firm attitude so this mistake will not be made again. Also, the controller said we were slightly west of localizer. Our map showed us on or very close to the localizer during the approach.

Title: B757 ON APCH TO SNA CROSSED THE SNAKE INTXN AT 3700 FT. THEY WERE SUPPOSED TO CROSS THE FIX AT 3300 FT.
Narrative: WE CROSSED SNAKE AT 3700 FT WHICH IS 400 FT ABOVE THE PUBLISHED XING ALT. ALL OTHER XING RESTRS ON THE EASTSIDE ARR ARE AT OR ABOVE BUT SNAKE RESTR IS A HARD ALT. AFTER READING THE ARR APPARENTLY I WAS SET UP INTO THINKING ALL XING RESTRS WERE AT OR ABOVE. MAY I SUGGEST THAT ALL XINGS BE AT A FIRM ATTITUDE SO THIS MISTAKE WILL NOT BE MADE AGAIN. ALSO, THE CTLR SAID WE WERE SLIGHTLY W OF LOC. OUR MAP SHOWED US ON OR VERY CLOSE TO THE LOC DURING THE APCH.
