Keep a lawn, but switch to drought-tolerant grass

Dry years come often enough to kill a thirsty lawn every few summers. Keep the lawn, reseed with a drought-tolerant mix, and put the beds on drip.

If you reseed, use a drought-tolerant mix and do it well clear of Jan, the month drought is most common here. Put beds on drip before the next dry year.
