Landscape Architect Irvine, CA

Irvine's Development Engineering Department checks landscape improvement plans. A submittal needs an application, a plan check fee, a construction permit form, three sets of plans signed by a licensed landscape architect, irrigation pressure-loss calculations, the approved case plans with the signed resolution and conditions, and a completed MWELO requirements form. Submittals must be complete and final. Partial submittals go back unless the City Engineer approves them (City of Irvine).

Standard Condition 3.32 requires landscape and irrigation plans conforming to Zoning Ordinance Chapter 3-15 (Landscaping Standards) and Title 5, Division 7 of the Municipal Code before building permit issuance (Standard Conditions). We read your project's conditions of approval first, so the sheets answer each one by number.

Irvine accepts landscape work in three phases. A pre-maintenance inspection needs the landscape architect's certificate of compliance, with the developer, contractor, and landscape architect on site. A 60-day maintenance period follows, with weekly inspections plus two scheduled ones at 30 days and 10 days before the period ends. A final inspection ends in written acceptance. Minor corrections after the first inspection carry a 30-day deadline (City of Irvine Bulletin 111). Plan the contractor's schedule and the owner's maintenance contract around those 60 days.

Irvine's MWELO form treats landscape under 500 square feet as exempt. Projects from 500 to 2,500 square feet fall in Category A, and projects over 2,500 square feet fall in Category B. The form states non-residential sites cannot use turf unless recycled water irrigates the turf. At final inspection, you provide a certificate of compliance, a certificate of completion, an irrigation schedule, and a maintenance schedule (City of Irvine Form 40-81). We prepare the water budget and hydrozone plan with the irrigation design, so the numbers match the sheets.

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). Our guides cover AB 1572 for developers and design teams and for existing commercial properties.

The City's Bulletin 180 requires new residential and non-residential developments to install both potable and recycled supply systems where disinfected tertiary recycled water is available from a municipal source. Waivers depend on proximity and cost-effectiveness. IRWD approves cross-connection testing before final approval or occupancy, and landscape projects also need an irrigation coverage test. The City and IRWD review plans in parallel, and both stamp the permit (City of Irvine Bulletin 180).

IRWD reports recycled water irrigates about 80% of public and commercial landscapes in its service area, through more than 500 miles of purple pipe and more than 6,000 metered connections (IRWD). Rates effective July 1, 2026 use four budget tiers. Potable water costs $2.18 per CCF in the first tier and $19.32 in the fourth. Recycled water costs $1.45 and $10.46 in the same tiers (IRWD rates). Overspending the budget costs real money, so plant selection and controller settings matter to your owner's operating cost.

Irvine requires a removal permit for right-of-way trees, including trees in medians and in paseo or open space areas next to homes and buildings. The requirement also covers significant trees under the code, such as eucalyptus windrows, along with parking lot and boundary trees. The City requires replacement in some cases, and applicants state the type, number, and gallon size of replacement trees or explain why none are planned (City of Irvine). A tree disposition plan documents each tree and the reason for each decision, so the permit reviewer finds answers in one place.

Irvine requires a Parking Lot Modification when an owner resurfaces, re-stripes, or re-grades a lot, or alters its landscaping. The applicant shows compliance with landscape coverage, which varies by zoning district. Boundary trees fall under Zoning Ordinance Section 3-15-4, and parking lot trees fall under Section 3-15-5. Applications go through the IrvineReady! portal, with a completeness check in about 2 business days and plan check in about 5 business days (City of Irvine). Confirm the current text of each section before you lock a tree count. We specify structural soil solutions for trees within paved areas so parking lot trees reach full size.

The Irvine Business Complex covers about 2,700 acres between John Wayne Airport and San Diego Creek. The City adopted the IBC Residential Mixed-Use Overlay to convert the area to urban mixed use, and the Vision Plan calls for parks, the San Diego Creek Creekwalk, and pedestrian-oriented streets in place of superblocks (City of Irvine). The overlay allows a maximum of 15,000 units at 30 units per acre minimum, with a 75-foot height limit, and residential requires a conditional use permit. The park standard is 3 acres per 1,000 residents, with 2 public and 1 private. Roof gardens and some courtyards earn open space credit (City of Irvine Form 43-64). Podium decks and courtyards carry real weight in this district, so we design them as part of the open space count from day one.

Standard Condition 2.17 requires a fuel modification plan for lots next to open space, prepared with OCFA, and OCFA approval is mandatory. Standard Condition 3.14 requires CC&R language sending plant changes in fuel modification zones through Director approval and OCFA requirements (Standard Conditions).

OCFA Guideline C-05 sets a standard 170-foot fuel modification area in three zones. Zone A is 20 feet minimum. Zone B runs 50 to 150 feet and is irrigated. Zone C/D covers 0 to 100 feet of thinned natural vegetation. A licensed landscape architect or equivalent professional prepares the plan from the approved plant list, and prohibited species include chamise, cypress, eucalyptus, palms, and pines. Conceptual plans go in with environmental review or before tract map approval, and precise plans go in before the planting plan or building permit is approved. OCFA approves first, and three inspections follow: vegetation clearance, final fuel modification, and owner turnover (OCFA Guideline C-05).

Orange County splits stormwater permits into a north area under the Santa Ana Regional Water Board and a south area under the San Diego Regional Water Board, with separate model WQMPs. The county's technical guidance sets a retention-first hierarchy of on-site retention, then on-site biotreatment, then subregional or regional options (Orange County Technical Guidance Document.pdf)). Irvine Standard Condition 2.11 requires a WQMP with BMPs and full-capture systems meeting the statewide Trash Provisions, and Condition 2.10 requires a Notice of Intent for disturbance of 1 acre or more. Bioretention areas are planting areas. Your civil engineer sizes the facilities, and we design the soil, plants, and irrigation inside them.

The Airport Land Use Commission for Orange County reviews land use proposals near John Wayne Airport. Projects over 200 feet or penetrating the 100:1 notification surface need FAA Form 7460-1 and ALUC approval (Orange County ALUC staff report). Rooftop and podium plans in the airport area follow the same height limits as the building, so we coordinate tree and equipment heights with your architect.

The Planning Commission approves use permits, conditional permits, variances, and adjustments, and meets the first and third Thursday of each month at 5:30 p.m. (City of Irvine). A conditional use permit package includes a site plan, a landscape plan, civil plans, an OCFA service request, and a 500-foot notice list (City of Irvine CUP checklist). We format each set for the reviewing group and answer planning, engineering, and fire comments together.
