You live nearby. If the hot weather (doubtless) and lack of rain/drought
continue (most likely), wonder if its going to affect the native live oaks?
Its not a common problem, so don't expect an answer from you know who to
interrupt.

What normally happens here is that the trees, shrubs and many times
herbaceous perennials will go dormant in the summer, but maintain.
These trees I have are hundreds of years old. If you were to cut one
down you would be able to see in the growth rings where drought
periods caused the dormancy. The ring measure for that year will be
negligible.
The only reason I water is to be sure the trees stay healthy. I use
the cheapest watering device for trees; a simple yellow ring with
holes in it. I set the timer after I measure an inch and how long it
takes to put an inch down, and move it all around the yard. It's the
most efficient way to water trees. I don't undertand why people have
sprinkler systems which "mist" the are with forced small drops instead
of impact sprinklers with much larger drops, much closer to the
ground. Those misters waste half the water they put out.

I forget. If you take a cross section of live oak and look at the vessel
arrangement. it takes skill. That will reflect the water requirement time.
When the vessels form they do not function until they are dead. At such a
time the water must be there. Send be a branch sample and I will dissect it
and take a picture and put it on a website explaining what I am saying. Let
me look and see if SHIGO has live oak dissections on his cd set. . I am in
PA.
I could not find a picture there. If I am correct they look like upside
down tornados. Thus thinking that during the earlywood formation the tree
would require a moderate amount of H2O while during the latewood period as
vessels die there would be a requirement for a great deal of H2O. Again if
you could mail me a branch piece about 4" in diameter or just a little
smaller by about 12 inches long I would dissect it and we could all see for
ourselves. E mail me at treeman@treedictionary.com for my address if you
would be so kind.
Found a picture of a dissection of cal. Live Oak. Unlike the red, black and
white oaks, the live oak has large vessels throughout the growth increment
equally sized from early to latewood. Thus stating that a reasonable amount
of water would be required for loading throughout the growing period in
girth. Just exactly when that is in your area I am not sure. If the tree
does not have its water then yes that would be a limiting factor. Just what
those limits are I do not know for sure. Of course two years of no water is
worse than one. In a natural setting nurse logs would be present with soil
contact in a sponge state and will be a water reservoir for dry times for
the trees. Humans have removed this feature from most places humans come in
contact. And if I am wrong I will be happy!
More on water here just for starters.
