Native and drought-tolerant plants are encouraged throughout Alameda County. State MWELO requires climate-appropriate plants for new landscapes, and EBMUD/ACWD offer rebates for lawn-to-native conversions.
Native plants adapted to the Mediterranean climate of Alameda County are strongly encouraged by the county, state, and local water utilities. The California Model Water Efficient Landscape Ordinance (MWELO) applies to new and rehabilitated landscapes over 500 square feet and requires a certain percentage of climate-adapted or native plants, limits high-water-use turf, and mandates smart irrigation controllers, drip systems, and hydrozoning. EBMUD and ACWD both offer cash rebates for replacing thirsty lawn with qualifying low-water and native landscapes. Common appropriate natives for Alameda County include coast live oak, toyon, California lilac (Ceanothus), manzanita, sagebrush, yarrow, California poppy, buckwheat, and deer grass. In Very High Fire Hazard Severity Zones, plant selection should balance drought tolerance with low flammability; CAL FIRE maintains a list of fire-wise plants. The Alameda County Resource Conservation District provides free technical assistance.
