The point was that it would be nice to have a square that encouraged stopping, and strolling and provided shade as opposed to the desolate lawns we refer to as parks, which have non-indegenous palms that provide no shade in a city that could actually use it.

it doesn't have to do with freezing (although some do only ;ive in areas where there is a freeze), has to do with ground moisture
annual rainfall:
San Diego 10 inches
Phoenix 7 inches
Washington DC 42 inches
New York 43 inches
Our climate is more similar to Phoenix than it is to the Eastern Seaboard where you see these gigantic mature deciduous trees.
Our air humidity might be a little higher in sd than phx due to the ocean, but our ground precip is similar. I used to live in Arizona, and they get the occasional winter storm like sd does, but they also get the summer "monsoon" going on now that brings thunderstorms, which we don't get here, so overall our rainfall is similar (this year our rainfall is actually below what theirs is)
And those types of trees, even if they could survive here, they would not thrive or become that large. have you been to the east coast and seen the trees, for example in New York? The are HUGE, the only trees that I have seen that grow that large here are the eucalyptus trees that have a totally different look but are able to live in the drier climate.
Even if you compare warmer east coast areas to SD, certain things can't live here. Coconut palms are a good example, thrive in Florida, die if you plant them here
Alot of the trees which you see in places like Washington DC's parks are temperate flowering fruits that only survive in that climate, such as the famous cherry trees that blossom in Spring. I was talking to people at the Japanese friendship garden in Balboa Park who said there are cherry trees that have been engineered to grow here but they don't get as big.
Even the deciduous trees that grow along the river in SD that someone brought up are nowhere near as big as those you see on the East Coast or in the midwest.
I do agree our parks could use denser foliage and shade as you mention, I just don't think those types of trees would grow that large here and even if they could it takes decades to reach that maturity. SD is a new city compared to East Coast, alot of those trees have had decades to mature
I am surprised that nobody here ever mentions Balboa Park - -it's not right downtown but it's close and I think it's amazing and it is certainly on the same grandeur as the famous parks of cities back east, even central Park, partly becuase it doesn't try to mimic them and it is unique to SD
