"... increase in asphalt and decrease in shade trees..."
Hells bells, I have a 20ac nursery with 40,000 trees and shrubs. I'll sell and install all the darned greenery they need. Just ask, folks in LA-LA Land! And be prepared to write a big check.
I like your attitude.
LA needs more "shade" trees. Palm trees just don't make it.
Of course trees take water, and there is not enough of that.
By the way, what is behind your selection of "7.62 x 51 mm"?
