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 Sep peak, and check your water utility for a turf-removal rebate before you dig.

Drought has been more common in 2016-2025 (6 years in 10) than in 2000-2015 (3.8 in 10).
