Summary

Hayward supports native and drought-tolerant landscaping. New projects must comply with the state Model Water Efficient Landscape Ordinance.

New development and retrofitted landscape water efficiency standards are governed by the Model Water Efficient Landscape Ordinance (MWELO) .

Full Breakdown

Hayward strongly encourages California native and drought-tolerant landscaping to reduce outdoor water use, which accounts for roughly half of residential consumption in the East Bay. Native species such as California lilac (Ceanothus), toyon, coast live oak, manzanita, and California poppy thrive in Hayward's Mediterranean climate with minimal irrigation after establishment. New or substantially renovated landscapes over 500 square feet must comply with the California Model Water Efficient Landscape Ordinance (MWELO) adopted under Government Code 65591 et seq. MWELO caps turf area, requires high-efficiency irrigation with smart controllers, and mandates a Landscape Documentation Package for permit review. EBMUD offers the Lawn Conversion Rebate of up to 2 dollars per square foot of turf replaced with native or low-water plants, plus free classes at the Shadelands campus.
