Thanks for the reply but can you elaborate on how RSA, which to my understanding is area beyond and not including the SWY, affects ASDA?
At locations where the area beyond the end of the pavement cannot be used as a runway safety area -- e.g., water, highway, etc. -- the airport management effectively "saws off" the distant end of the runway, designating ("Declaring") that a portion of the pavement is now part of the RSA and cannot be used in calculation of distance for Accelerate Stop.

See FAA AIM 4-3-6-c
