MWELO requires water-efficient landscapes including native plants for new installations over 500 square feet. Delta-adapted native plants (tule, valley oak, native grasses) are encouraged in Isleton.
California's Model Water Efficient Landscape Ordinance (MWELO, 23 CCR 490) applies to new residential landscapes over 500 square feet and requires water-budget calculations, hydrozoning, and efficient irrigation. While not mandated, native and climate-appropriate species satisfy water-use-efficiency targets more easily. Delta-appropriate natives for Isleton include valley oak, Fremont cottonwood, California wild rose, deergrass, and native tule in wetland margins. The Sacramento Stormwater Quality Partnership encourages bioretention with native plants for NPDES MS4 compliance. No city-specific native-plant mandate exists.
