My family is conserving water in N California to water 100 ft (30 m) trees to prevent them from weakening and being colonized by borer insects which will then kill the trees. Having a tall dead around suburban homes is a very dangerous thing. They're also in an extremely risky area for fast-moving forest fires and a dried tree is fuel too. In addition to enough water, trees often need systemics (chemical treatment if there are specific pests) and annual inspections by arborists.
