Does this account for the massively depleted aquifers thoughout the state?

My understanding of aquifers is that many of them take many years to fully replenish depending on their size and the makeup of the substrate. I remember a few years ago during the severe droughts there was much worry over aquifer depletion and land subsidence[1]. The primary concern was that certain soil types would compact permanently then no longer be able to hold water ever again. I doubt one season of heavy rainfall and snow melts solves that issue.

It's been raining every couple of days in sunny San Diego for like 3 months

There really hasn't been such a significant amount of rainfall here in years, I just worry about the fire danger coming in the fall because of all of the new growth.

Many years being on the scale of tens to thousands of years. Cody did a great video on his channel showing confined aquifers, how they work, and why they recharge so slowly:
