Landscape Architect Orange County, CA
Commercial landscape architecture, land planning, and irrigation design for Orange County industrial, logistics, multifamily, mixed-use, and master-planned projects.
Commercial Landscape Architect in Orange County
Evergreen Design Group is a commercial landscape architect in Orange County with a fully remote team and California Landscape Architect License 7158. We work for land developers, civil engineering firms, architects, and design-build contractors. We do not take homeowner work.
Much of the work here is infill, redevelopment, or the final phases of a master plan. Parcels are tight, utilities are already in the ground, and every city reviews landscape plans against its own code. You need a team experienced in those reviews, producing sheets built to pass them.
Our licensed landscape architects prepare land planning studies, planting plans, irrigation designs, tree disposition plans, amenity plans, and hardscape plans in-house. You work with one team and receive one coordinated set, ready to sit beside your civil and architectural plans.

Who We Work With and What You Build in Orange County
Land developers bring us in during feasibility and entitlement, when open space, amenity siting, and street frontage still move. Civil engineering firms share base files with us so grading, drainage, and utility conflicts get settled before plan check. Architects need planting and hardscape sheets matched to the building footprint, fire access, and ADA routes. General contractors and design-build firms want construction documents with clear quantities and details for accurate pricing and build-ready sheets. Owners and public agencies, including cities, school districts, and special districts, expect sheets built to agency standards and procurement rules.
Industrial and logistics sites in Anaheim, Fullerton, Santa Ana, and Buena Park call for perimeter buffers, parking lot planting, truck court screening, and irrigation built for low maintenance cost. Multifamily and mixed-use projects range from garden-style apartments and build-to-rent communities to podium projects in dense districts such as the Anaheim Platinum Triangle and the Irvine Business Complex. Courtyards and amenity decks over structure need early coordination with your architect and structural engineer.
Master-planned communities in Irvine, Lake Forest, and Rancho Mission Viejo layer master developer design criteria and HOA standards on top of city code. Retail renovations, medical office, hospitality, and corporate campuses near John Wayne Airport and South Coast Metro need plans built for heavy foot traffic and tight schedules. Civic and institutional work, from school campuses to parks, follows agency design standards and public bidding rules.
Local Development Conditions Behind Your Scope
These conditions drive scope, fee, and schedule on Orange County projects. We address them at the site plan stage, before your civil engineer locks the layout.
Water budgets and local ordinances
Orange County cities adopt their own water efficient landscape ordinances based on the state MWELO, and some apply tighter thresholds than the state baseline. Your permit set needs a water budget, a hydrozone plan, and plant factor documentation the reviewer accepts on the first pass. We prepare those documents with the irrigation design, so the numbers match the sheets.
Recycled water in Irvine Ranch Water District territory
Irvine Ranch Water District waters about 80 percent of the public and commercial irrigated landscape in its service area with recycled water. Recycled systems run on a separate purple pipe network, follow state use area rules and signage, and stay clear of potable lines. Your irrigation plans show those details, and the district reviews them. Confirm early whether your parcel connects to recycled water. The answer changes mainline routing, controller selection, and plant palette.
AB 1572 and nonfunctional turf
Starting January 1, 2028, California bars potable water irrigation of nonfunctional turf on commercial, industrial, and institutional properties. HOA common areas follow on January 1, 2029. Turf irrigated with recycled water falls outside the ban, and turf used for recreation or gathering stays allowed (MWDOC). Design new sites without decorative turf on potable water, and expect owners of existing properties to ask for retrofit plans. Our guides cover AB 1572 for developers and design teams and for existing commercial properties.
Fire and the wildland interface
New commercial and multifamily structures next to wildland, or in a designated fire hazard severity zone, need a fuel modification plan. OCFA Guideline C-05 sets a standard 170-foot zone. Zone A is irrigated and runs at least 20 feet. Zones B, C, and D run at least 50 feet each. Every plant comes from OCFA's approved list, and palms (except King palms), eucalyptus, pines, junipers, and cypress are prohibited (OCFA Guideline C-05).
Review happens in stages. The conceptual plan goes in before the tentative map. The precise plan goes in before grading or building permits and before fire master plan approval. OCFA recommends a licensed landscape architect prepare the plans. Cities with their own fire departments, such as Orange, publish separate guidelines.
Entitlement, streetscape, and plan check
Planning, public works, building, and fire review different sheets, and each city sets its own streetscape standards, parking lot shade rules, and tree ordinance. Conceptual landscape plans support discretionary review. Construction documents go to plan check. In Irvine and other master-planned communities, master developer design criteria and HOA guidelines sit on top of city code. Projects in the coastal zone add local coastal program review.
Grading, stormwater, and civil coordination
Water quality management plans put bioretention basins, swales, and treatment areas inside planting areas. Your civil engineer sets those grades. We set plants, soil, and irrigation for them. Sharing base files early keeps utility conflicts, tree locations, and slopes from forcing a redesign at plan check.
Landscape Architecture, Land Planning, and Irrigation Services in Orange County
Our land planning in Orange County starts at feasibility. We test site layouts against zoning, open space, buffer, and amenity requirements. Then we prepare conceptual landscape plans, exhibits, and open space calculations for planning review. When staff comments arrive, we answer with your civil engineer and architect, so the city receives one coordinated response.
As a commercial landscape architect in Orange County, we design entries, streetscapes, plazas, parking field planting, screening, and open space. We design to city code and to the maintenance budget your owner will carry. Industrial developers will find more in our guide to landscape architects for industrial projects.
Planting plans in Orange County balance MWELO plant factors, hydrozones, shade tree requirements, and fire-resistant palettes in fuel modification zones. We select plants for the water source on your site, potable or recycled, and for the crew who will maintain them.
Tree disposition plans in Orange County document species, caliper, and condition for each regulated tree. They then show removals, preservation, mitigation, and replacement. Sequence matters, so read our guide on who should conduct your tree survey before you order one.
Amenity plans in Orange County cover pool courts, fitness areas, courtyards over structure, tot lots, dog parks, and gathering spaces for multifamily, mixed-use, and senior living projects. We coordinate pool equipment, ADA routes, and drainage with your architect and civil engineer before permit submittal.
Hardscape plans in Orange County detail paving, walls, plazas, seat walls, and site furnishings on the same grading base as the rest of the site. Joint layouts and material choices account for seismic movement, thermal cycling, and drainage.
Licensed in-house staff prepare our irrigation design services in Orange County. Scope covers zoned layouts, controller and equipment specifications, flow and pressure calculations, backflow documentation, water budgets, and recycled water systems built to district standards.
Construction documents and consultant coordination
We issue stamped construction documents formatted for each city’s plan check. Sets include planting, irrigation, tree, and hardscape sheets, specifications, and water calculations. We share CAD files with your civil engineer, architect, and fire consultant, review their submittals for conflicts, and answer plan check comments. For multi-site programs, our program management team keeps standards consistent across projects.
Orange County Cities and Submarkets We Serve
Our team works remotely and serves north county cities such as Anaheim, Fullerton, Brea, and Buena Park, where industrial parks, infill multifamily, and the Platinum Triangle drive demand. Central county projects run through Santa Ana, Tustin, Orange, and Costa Mesa, including mixed-use and office renewal near South Coast Metro and the airport area. In Irvine itself, we work in the Irvine Business Complex and in village communities governed by master developer criteria.
Sites in Lake Forest, Mission Viejo, Rancho Santa Margarita, Aliso Viejo, and Laguna Niguel often back to open space, so fuel modification sets the layout first. Coastal projects in Newport Beach, Huntington Beach, and Dana Point add local coastal review.
Our team also serves Los Angeles, the Inland Empire, San Diego, and Northern California. See the full list of areas we serve.
Orange County Landscape Architect FAQs
Do Orange County commercial permits require a licensed landscape architect?
Requirements vary by city, so confirm with your planning or building department. Commercial permit sets typically carry a licensed landscape architect’s stamp, and OCFA recommends a licensed landscape architect or equivalent design professional for fuel modification plans. Evergreen holds California Landscape Architect License 7158.
When should you bring in a landscape architect?
Bring us in at site planning, before the civil plan set is far along. Water quality areas, fuel modification zones, open space, and tree preservation all shape the layout. Settling them early cuts revision cycles during review.
Do you design recycled water irrigation systems?
Yes, where recycled water is available. We design on-site systems to district requirements, including separation from potable lines, signage, and backflow documentation. Confirm availability with your water district at the start of design.
How does AB 1572 affect planting plans for new projects?
Starting January 1, 2028, decorative turf on potable water is out for commercial, industrial, and institutional sites. We replace decorative turf with low-water planting, limit turf to recreation and gathering areas, or specify recycled water where the district offers a recycled service.
Do you work as a subconsultant to civil engineers and architects?
Yes. Subconsultant work for civil engineering and architecture firms is one of our most common structures. We contract with your firm, share CAD files, attend coordination meetings, and deliver sheets formatted for your set.
How fast do you turn initial deliverables?
Most standard commercial landscape packages take two to four weeks for initial deliverables. We set full construction document timelines at kickoff.
