Palo Alto FAQ
Is there a turf removal rebate?
Valley Water and sometimes BAWSCA offer rebates per square foot of lawn replaced with low-water or native plants. Apply before starting work.
Can I plant natives under my oak?
Yes, but avoid summer irrigation and disturbance within the tree protection zone. Dry-shade natives like coffeeberry and currant work well.
San Jose FAQ
Does Santa Clara County require or restrict native plants?
It does not require them, but it strongly encourages them. The County's Sustainable Landscape Ordinance offers compliance paths that reward native and low-water plantings for qualifying new landscapes, and nothing prohibits a native garden.
Can my HOA stop me from planting a drought-tolerant native garden?
No. California Civil Code section 4735 prohibits HOAs from banning low-water-using plants as a replacement for turf, and HOAs cannot fine owners for cutting irrigation during a declared drought emergency.
