@Tes yeux noirs,
I live in a duplex situation, ordinary little stucco place (sniffs, I miss my California bungalows) and yah, one of the first things I did was take out some trees.
On the sins of people who plant stuff or design it, I think my worst sin, metaphorically, was obeying city rules, or once in a while the developer's rules. Usually the cities though. I was early on into drought resistant plants (California, the Los Angeles area itself long known as semiarid desert - there were no native tree in the LA basin itself, south of the Santa Monica Mountains), and used some fair amount of natives. But, in the projects in the more desert areas where a lot of development was happening, the city rules required lawns.
Lawns have had their revenge.
I am pissed at myself for not being noxious about that.
I did quit taking on those projects. The last big project, actually small relative to the desert ones, when I was on my own, was designing for several acres of condos where the developer was a chinese client of my former japanese boss and knew me and listened - so I got what I wanted, reasonable non thirsty plants, with a lot of drip irrigation, a lot of calcs done re the water usage. The city, in retrospect given other cities, did not insist on lawns. I guess all this time later that they had someone from a good local uni, Cal Poly, come and advise them re requirements to developers.
