RESA is not part of the declared distances for performance purposes. It's an aerodrome requirement to provide them so in the event of an overrun/undershoot the aircraft has some extra safety margins. Minimum required length of RESA for most runways is 90m but recommended is 240m.
If a stopway is provided then the RESA origin starts 60m (end of runway strip) beyond the end of stopway. If stopway is not provided then the ASDA/TORA will be the same and RESA origin starts 60m beyond.
RESA width has to be at least twice runway width. Overrun/undershoot RESA lengths vary depending on position of end of TORA/ASDA and the start/end of LDA.

EMAS
FYI
KFLL Runway 10R/28L has 600 ft of EMAS at each end which is supposed to be equivalent to a normal 1000 ft RESA for stopping distance. Obviously, it would not be suitable for undershoot protection.
The east end of the runway has a 55 ft shear drop off down to grade level due to the sloping required to allow a 4 track railroad and a 6 lane highway to pass underneath.

Unlike the FAA plates, for some unknown reason, Jeppesen(Boeing) does not show runway gradients on their airport depictions.
