Encinitas, California just became the first city in San Diego County to pass a native plant ordinance. New developments must use 50% Southern California natives. Near open space, it is 100%. And Calscape is the official plant guide.
On March 25, 2026, the Encinitas City Council voted unanimously to adopt a native plant ordinance. The city is the first in San Diego County, and possibly the first in California, to require native plants by law for new development. The ordinance does not apply to single-family homes or ADUs. It targets design review permits, major use permits, and city projects that include landscaping.
The requirement is 50% Southern California native plants for most qualifying projects. For landscaped areas within 50 feet of conserved habitat, the requirement jumps to 100%. City-owned land also requires 100% native landscaping. The plant list comes from Calscape, the database maintained by the California Native Plant Society. The approved palette includes species from 11 Southern California ecoregions, giving landscape architects flexibility while keeping the plants regionally appropriate.
The ordinance has been in the works for years. The Encinitas Planning Commission began informally requiring 50% native plants on certain projects more than a decade ago. In 2021, Councilmember Joy Lyndes, a landscape architect, pushed to make the practice law. A citizen group called Native Plants for Encinitas formed in 2024 to support the effort. The city allocated $150,000 to hire SWCA Environmental Consultants to draft the technical language.
Encinitas sits on the coast between Carlsbad and Solana Beach. Its native ecosystem is coastal sage scrub, a community of drought-tolerant shrubs and wildflowers that supports a huge diversity of insects, birds, and reptiles. Plants truly native to the area include California sagebrush (Artemisia californica), black sage (Salvia mellifera), Cleveland sage (Salvia clevelandii), toyon (Heteromeles arbutifolia), lemonade berry (Rhus integrifolia), and coastal dudleya (Dudleya caespitosa). These are not exotic garden specimens. They are the plants that evolved with the local climate, the local soils, and the local pollinators.
The ordinance explicitly bans invasive species defined by the California Invasive Plant Council and the San Diego County Invasive W**d Watch list. Giant reed, fountain grass, pampas grass, and ice plant are all prohibited. These species spread aggressively, increase fire risk, and crowd out the native coastal sage scrub that makes Encinitas ecologically unique.
Don Rideout, a member of the California Native Plant Society's San Diego Chapter, supported the ordinance because it addresses what he calls "the extinction of the little things that run the world, namely insects and other pollinators." He said it is time for constructed landscapes to do more than look pretty. "We need to rewild some of our developed spaces on a scale that is possible within Encinitas."
The city is also planning a native plant demonstration garden in a neighborhood park, plus a rebate program of up to $200 for residents who buy qualifying native plants. The ordinance is not retroactive. It does not force existing homeowners to dig up their lawns. But every new development, every new park, every new city project will now include at least half native plants. Over decades, that changes the look and the biology of the entire city.
Calscape is the official guide. If you are building in Encinitas and your landscape architect does not know what Calscape is, they are about to learn.
