Interestingly, that 90-year lag was unimproved from an earlier presentation from 2011 — at the 2011 Orange County City Infrastructure Summit, Association of California Cities (see at 1:26 in the video at this link):

ABOUT THE SIMULATIONS & FILM
The images and simulations are based on the best available science – including CoSMoS 3.0 sea-level rise projections developed by the United States Geological Survey (USGS) that have been previously used in multiple studies in this area. Virtual Planet’s work was commissioned by the California Coastal Protection Network. The views or opinions expressed during the film do not necessarily represent those of Virtual Planet Technologies or its employees.
