I don't have any recent paper charts in the house but the 2005 Phoenix sectional says "Class E Airspace exists at 1200 ft AGL unless otherwise designated as shown above". The "above" refers to the blue staggered line used to differentiate the floors of class E greater than 700 ft above surface. All these blue staggered lines that existed in 2005 have been wiped off the current chart. I haven't found any regulatory reference for the change.
