Plan for drought as normal: shrink the lawn, go drip and natives
Drought is the normal state of things here. Most of the yard goes to natives and gravel on drip; any grass that stays is a small, tough patch.
If you are replacing turf, plant natives in fall so roots set before the May peak, and check your water utility for a turf-removal rebate before you dig.
This is one step drier than the yearly count alone suggests, because 27% of growing-season weeks here were in drought.
