Landscape Architecture Firm Irvine, CA
Evergreen Design Group is a landscape architecture firm in Irvine operating at both a local and national scale. We hold active licensure in 40+ states, including California Landscape Architect License ⁄7158 — and our Irvine office is staffed by landscape architects who work daily within Orange County’s regulatory environment, development review processes, and project delivery expectations.
As a landscape architecture firm in Irvine, we bring jurisdiction-specific knowledge of the City of Irvine’s development standards, Irvine Company design overlay requirements, MWELO enforcement protocols, and CALGreen compliance requirements that shape every commercial project in this market. That local depth, backed by the resources and process discipline of a nationally operating firm, is what sets our landscape architecture firm in Irvine apart from both local-only practices and large national firms without a meaningful presence in Orange County.
Our Irvine landscape architecture practice is exclusively B2B. We do not take on individual homeowner projects. Our clients are architects, civil engineers, land developers, and design-build contractors who need landscape architects in Irvine who understand entitlement timelines, deliver construction-ready documentation, and integrate cleanly into their project teams.
Landscape Architecture Services in Irvine, CA
We function as a true design partner — integrated into your project team from early-phase land planning in Irvine through construction document issuance. Every service is performed in-house by our licensed California landscape architects with no subcontracting of scope.
Land planning in Irvine requires navigating one of the most structured and overlay-governed development environments in Southern California. Our land planning Irvine services integrate directly with your civil site layout to address open space configurations, buffer yard requirements, native plant preservation zone placement, amenity siting, and streetscape frameworks that satisfy the City of Irvine’s development review standards from the first submittal.
Our land planning Irvine scope covers the full range of commercial development types: multi-family and build-to-rent communities, mixed-use and town center projects, retail and office development, industrial and logistics facilities, and institutional campuses. For projects subject to Irvine Company design criteria or community HOA overlay standards, we research and incorporate those requirements into the land planning scope at the outset — before they become a revision cycle during entitlement review.
Early land planning coordination is particularly valuable in Irvine because the city’s layered regulatory framework — municipal landscape ordinance, MWELO water budget parameters, CALGreen shade requirements, and applicable HOA overlay standards — creates interdependencies between landscape architecture decisions and civil engineering decisions that must be resolved at the site planning stage, not after the civil plan set is substantially complete.
Comprehensive tree surveys and disposition plans prepared to meet City of Irvine and Orange County development permit requirements. Our plans include field-verified inventories, species and caliper documentation, condition assessment, regulated removal impact analysis, mitigation calculations, and replacement specifications formatted to support the applicable jurisdiction’s development review process.
Our landscape architects in Irvine produce complete, permit-ready construction document sets tailored to City of Irvine and Orange County jurisdiction requirements. Species selection is calibrated to the local climate, applicable water conservation requirements, HOA design guidelines, and any Irvine Company or community-specific overlay standards that govern the project site.
We specify drought-tolerant and water-efficient plant palettes that comply with MWELO plant factor requirements, CALGreen shade canopy standards, and any fire-resistant species requirements applicable to the project’s fire hazard severity zone designation. Plant coverage documentation, spacing calculations, and species counts are included to support permit compliance review.
Pool surrounds, fitness areas, outdoor recreation spaces, tot lots, dog parks, and resident amenity packages for multi-family, senior living, and mixed-use developments throughout Irvine and Orange County. Designs are developed to HOA standards, local building codes, ADA accessibility requirements, and any applicable Irvine Company or community overlay design criteria.
Pedestrian plazas, entry features, streetscapes, seat walls, paving systems, and structured outdoor spaces for commercial, mixed-use, and institutional projects in Irvine and Orange County. Material specifications account for Irvine’s seismic environment, thermal cycling, impervious surface standards, and the drainage requirements applicable to each project’s jurisdiction.
Irrigation design in Irvine is governed by California’s Model Water Efficient Landscape Ordinance (MWELO) — one of the most rigorous water conservation regulatory frameworks in the country — along with any local Irvine amendments and Irvine Ranch Water District requirements applicable to the project site. Our irrigation design Irvine team produces fully MWELO-compliant designs for commercial and multi-family projects throughout Orange County, including Water Efficient Landscape Worksheets (WELO), plant factor documentation, flow and pressure calculations, controller specifications, backflow prevention documentation, and irrigation scheduling documentation formatted to satisfy Irvine’s permit review requirements.
Irrigation design in Irvine also requires coordination with the Irvine Ranch Water District (IRWD), which maintains its own tiered rate structure and landscape water budgeting requirements for commercial accounts. Our irrigation design team produces water budget calculations and system specifications that address both MWELO compliance and IRWD account requirements as integrated scope — not separate deliverables. Smart controller specifications, irrigation scheduling documentation, and reclaimed water system integration are included as standard scope on applicable projects.
MWELO compliance for irrigation design in Irvine is built into our workflow from the initial site planning stage. Water budget parameters, plant factor calculations, and irrigation efficiency specifications are established during design development so that the construction document package arrives at Irvine’s plan check in approvable form.
Irvine Project Considerations: What Your Landscape Architect Needs to Know
Irvine is a highly regulated, master-planned city, and the environmental and jurisdictional context of the greater Orange County region introduces specific design and compliance requirements that shape every commercial landscape architecture project. The landscape architects at our Irvine office understand these requirements from direct project experience in this market.
MWELO and Water Conservation Compliance
Irvine enforces California’s Model Water Efficient Landscape Ordinance rigorously. Projects above the threshold square footage require a Water Efficient Landscape Worksheet (WELO), plant factor documentation, and irrigation audit protocols as conditions of permit approval. Our team builds MWELO compliance into the design workflow from the initial site planning stage — not as a correction at permit submittal. We incorporate any local Irvine amendments and applicable Irvine Ranch Water District requirements that apply beyond the state baseline.
CALGreen and Shade Requirements
CALGreen mandates shade coverage for parking areas on nonresidential projects. Our landscape architects in Irvine calculate shade compliance as part of the planting and site design process, coordinating tree placement with your civil team to ensure it is supported by the site layout and utility clearances. Shade canopy calculations are integrated into our construction document deliverables as standard scope.
Wildfire Risk and Fire-Resistant Design
Portions of Irvine and surrounding Orange County are designated Very High Fire Hazard Severity Zones by CAL FIRE. For projects in or near these zones, defensible space requirements and fire-resistant plant palette selection are integrated into the landscape design approach from the initial site planning stage. We identify the applicable fire hazard severity zone designation during project onboarding and incorporate CAL FIRE compliance requirements into planting and hardscape specifications accordingly.
Seismic Considerations for Hardscape
Irvine sits within a seismically active corridor in proximity to the Newport-Inglewood and San Joaquin Hills fault systems. Our hardscape designs for this market incorporate expansion joint strategies and material selections suited to seismic movement — a detail that protects long-term infrastructure performance and reduces maintenance liability for your client.
Master-Planned City Overlays and HOA Guidelines
Irvine is one of the most extensively planned cities in the United States. Many parcels carry design criteria from the Irvine Company or community-specific HOA guidelines that govern plant palettes, hardscape materials, and streetscape standards beyond the City’s baseline landscape ordinance requirements. Our landscape architects in Irvine research applicable overlay requirements during project onboarding to prevent rework during design review.
Irvine Ranch Water District Coordination
Commercial and multi-family development projects in Irvine are typically served by the Irvine Ranch Water District (IRWD), which maintains its own landscape water budgeting requirements, tiered rate structure, and reclaimed water availability standards that interact directly with MWELO compliance obligations and irrigation design in Irvine. Our irrigation design team coordinates water budget calculations and system specifications with both the City’s MWELO requirements and IRWD’s service standards as standard project scope.
Project Types We Support in Irvine and Southern California
Multifamily and Mixed-Use Residential Development
From garden-style apartments to large master-planned communities, we provide full landscape architecture and irrigation design packages aligned with City of Irvine requirements, HOA standards, and any applicable Irvine Company overlay criteria. We work alongside civil engineers and architects from schematic design through construction documents and permit submittal.
Commercial and Mixed-Use Development
Pedestrian plazas, entry features, streetscapes, stormwater-compliant planting, and commercial hardscape for retail centers, office campuses, mixed-use commercial properties, and hospitality projects across Orange County. Designs balance code compliance, CALGreen requirements, and the operational durability demands of each project type.
Industrial and Logistics Facilities
For industrial sites, we focus on code-compliant landscaping that supports operational needs — perimeter buffers, parking lot planting, low-maintenance palettes, and efficient irrigation systems that minimize long-term maintenance burden while satisfying Irvine and Orange County landscape ordinance requirements.
Civic and Institutional Projects
Our team has experience with publicly funded and institutionally managed projects that require compliance with ADA standards, CEQA review processes, and agency-specific design and documentation requirements across Orange County.

Frequently Asked Questions: Landscape Architects Irvine, CA
Landscape architects in Irvine prepare land planning studies, planting plans, irrigation designs, tree disposition plans, and hardscape construction documents for commercial, multi-family, and industrial development projects. In Irvine specifically, they navigate the city’s master-planned overlay requirements, Irvine Company design criteria, MWELO water conservation compliance, CALGreen shade standards, and applicable CAL FIRE defensible space requirements — producing deliverables formatted for City of Irvine plan check and permit submittal.
The Irvine Ranch Water District (IRWD) is the primary water provider for most commercial and multi-family development in Irvine. IRWD maintains its own landscape water budgeting requirements, tiered commercial rate structure, and reclaimed water availability standards that interact directly with MWELO compliance requirements. Our irrigation design team produces water budget calculations and system specifications that address both MWELO and IRWD requirements as integrated baseline scope on every Irvine commercial project.
Land planning Irvine scope involves site feasibility analysis, conceptual site planning, open space configuration, entitlement documentation, and coordination of MWELO water budget parameters, CALGreen shade requirements, HOA overlay standards, and Irvine Company design criteria into the site layout. It should begin as early as possible — before the civil plan set is substantially developed — so that these interdependencies are resolved at the layout stage rather than generating revision cycles during entitlement review.
Yes. MWELO compliance is built into our irrigation design workflow from the initial site planning stage. We produce Water Efficient Landscape Worksheets (WELO), plant factor documentation, water budget calculations, controller specifications, and irrigation scheduling documentation as standard deliverables on every applicable commercial project in Irvine and Orange County — not as a permit submittal correction.
No. Our practice is exclusively B2B. We work with architects, civil engineers, land developers, and design-build contractors. We do not take on individual homeowner projects.
Yes. Evergreen Design Group holds California Landscape Architect License ⁄7158, issued through the Landscape Architects Technical Committee (LATC). All landscape architectural services for California projects are performed under this license by our licensed professionals.
Yes — that is one of our most common engagement structures across the Orange County market. We integrate into your project team and deliver the full landscape architecture scope as a subconsultant, coordinating directly with your project manager and other disciplines throughout the design and entitlement process.
Many parcels within Irvine carry Irvine Company design criteria that govern plant palettes, hardscape materials, signage zones, and streetscape standards beyond the City’s baseline landscape ordinance. These criteria are in addition to — not instead of — City of Irvine permit requirements. Our landscape architects research and incorporate applicable Irvine Company overlay requirements during project onboarding so they are addressed in the design from the outset, not flagged as deficiencies during the entitlement review process.
As early as possible — ideally at the site planning stage, before the civil plan set is substantially developed. Early engagement allows MWELO water budget parameters, CALGreen shade compliance, HOA and Irvine Company overlay standards, and City of Irvine landscape ordinance requirements to be integrated into the site layout before those decisions are locked in. Projects that bring landscape architecture into the land planning Irvine process early consistently produce cleaner submittals and fewer revision cycles.
We work across multi-family residential, mixed-use, commercial, industrial, and institutional project types throughout Irvine and Orange County. Common project types include master-planned and garden-style apartment communities, build-to-rent developments, retail and office projects, industrial and logistics facilities, and civic and institutional campuses. All work is B2B — performed for developers, architects, civil engineers, and design-build contractors.
