Landscape Design in Corona del Mar

The growing conditions here are among the best on the coast. Corona del Mar sits in Sunset climate zone 24, the mild marine climate dominated by the ocean: winter lows average only in the low to mid 40s, summers stay cool, and the air is seldom really dry, so frost-tender plants rarely go out of bloom. That’s an open invitation to the Mediterranean palette we work in. Olives, lavender, rosemary, rockrose, salvias, and gray-leaved coastal natives all flourish here, and the mild year means a thoughtfully designed garden holds its beauty in every month, not just a spring peak.

A living catalogue on the main street

The neighborhood itself proves the point. Sherman Library and Gardens occupies a full city block in the heart of Corona del Mar, a botanical garden founded in 1966 that grows over a thousand species, from rare cacti and succulents to lush exotics, all in this one seaside microclimate. Few neighborhoods anywhere have a living catalog of what their climate can do sitting right on the main street. We design private gardens in that same spirit: proof that water-wise and lush aren’t opposites.

Designing at village scale

Scale is the defining design challenge in the Village, the compact grid of blocks inland of Pacific Coast Highway known as the Flower Streets, where the streets carry names like Acacia, Begonia, Carnation, Dahlia, Orchid, and Poppy. Lots are narrow, homes sit close to the sidewalk, and the garden is often a front-row experience for everyone walking to the beach. That calls for composition, not accumulation: a disciplined plant palette, layered heights, warm materials, and containers and courtyards treated as rooms. Closer to the bluff, around Ocean Boulevard, Lookout Point, and the cliffs above Corona del Mar State Beach and Pirates Cove, salt wind and exposure move to the front of the plant list, and coastal-proven species earn their place.

The water rules that apply here

Because Corona del Mar is part of Newport Beach, water comes from the City of Newport Beach Utilities Department, and the city’s permanent conservation program applies: no landscape watering between 9 a.m. and 5 p.m., a ten-minute limit per station for automated systems, and a seasonal schedule of four watering days a week in summer and two in winter. Meanwhile, state law AB 1572 is phasing out potable-water irrigation of purely decorative turf, reaching HOA common areas by 2029. Our designs treat all of this as the baseline: hydrozoned plantings and efficient irrigation designed in from the start, so the garden thrives inside the rules rather than straining against them.

Runoff, first rather than last

On the bluff, everything a garden sheds heads toward the ocean, which makes runoff the first design question rather than the last. Permeable paving and planted beds that sit low enough to take what the paths and roof shed will hold a winter storm on site. Soil built with compost keeps that water where the roots can reach it through the dry months, so the planting needs very little help. Choose species adapted to this coast and there’s nothing in the runoff worth worrying about.

Root & Branch Landscapes brings landscape design, installation oversight with maintenance crew training, and consulting to Corona del Mar homeowners, HOAs, and property managers. We carry a garden from first concept through installation oversight, then train the crews who maintain it so it matures as designed. On lots this visible, in a climate this generous, the difference a considered landscape makes is immediate. We’d love to help you make it.

Every Corona del Mar project is grounded in regenerative, water-wise practices, so your landscape stays lush and beautiful while using a fraction of the water a traditional lawn demands. We design, manage the build, and guide the crews who keep it thriving.
