Landscape Architects Ohio
A Licensed Landscape Architecture Firm Serving Ohio’s Development Community
Evergreen Design Group is a national landscape architecture firm with active Ohio licensure and 21 years of practice serving land developers, civil engineers, architects, and design-build contractors. We provide land planning, landscape architecture, and irrigation design across Ohio—from the high-growth suburban corridors surrounding Columbus and Cincinnati to the industrial and mixed-use development markets in Cleveland, Dayton, Toledo, and beyond. In Ohio, the title ‘Landscape Architect’ is legally restricted, and practicing without a license is strictly prohibited.
Ohio’s development environment is more complex than it looks from the outside. Freeze-thaw climate cycles, variable soils across geologic regions, Ohio EPA stormwater requirements, and jurisdiction-by-jurisdiction landscape code variation all shape what a well-executed landscape construction document set has to address. Our Ohio landscape architects are fluent in that environment. In addition to individual licensure, landscape architecture firms in Ohio must hold a Certificate of Authorization to provide services. We carry full professional liability coverage and maintain the bonding required to protect clients and their projects through construction. We design to meet these requirements—not work around them.
Landscape Architecture Services in Florida
Our land planners work alongside civil engineers and developers at the earliest stages of site development—establishing open space frameworks, landscape buffers, site circulation, and connectivity systems that support entitlement and hold up through final design. In Ohio’s growth markets, that means understanding what county and municipal planning departments are looking for at the zoning and PUD level before the first design sketch is produced.
Ohio’s rainfall patterns are uneven. The state receives adequate annual precipitation in most regions, but mid-summer dry periods—particularly in central and southern Ohio—can stress newly established plantings on development sites without supplemental irrigation. Our irrigation designs balance efficiency with performance, sized appropriately to establishment needs and long-term maintenance expectations. We design systems that comply with applicable local irrigation standards and integrate readily with smart controller technology.
We produce fully coordinated construction document sets covering planting design, hardscape design, tree disposition plans, and community amenity packages. Our Ohio landscape architects select plant material suited to Ohio’s USDA Zones 5b through 7a, specifying species with demonstrated cold hardiness, freeze-thaw resilience, and appropriate site adaptability—not simply plants that look good on a palette board. Hardscape design accounts for Ohio’s frost depth requirements and the particular vulnerability of paving systems, retaining walls, and drainage structures to seasonal freeze-thaw stress. We deliver full-service design from concept through permitting and construction documentation.
Ohio-Specific Design and Regulatory Considerations
Ohio is a large, geologically diverse state, and the design and regulatory context varies meaningfully across its regions. Our Ohio landscape architects work across the full state and understand those regional distinctions. Licensed landscape architects in Ohio are authorized to prepare sealed drawings, serve as landscape architect of record, and manage construction-phase contracts in accordance with state licensing requirements.
Freeze-Thaw Climate and Hardscape Performance
Most of Ohio falls within USDA Plant Hardiness Zones 5b to 6b, with Zone 7a in the southernmost counties along the Ohio River. Extended freeze-thaw cycling is the dominant climate stressor for hardscape systems—pavers, retaining walls, curbing, and drainage structures are all vulnerable to frost heave and spalling if not designed and detailed appropriately. We specify materials rated for Ohio’s freeze depth conditions and detail expansion joints, drainage provisions, and base course depths to match.
Variable Soil Conditions Across Ohio’s Geologic Regions
Ohio’s soils reflect its glacial history and vary substantially by region. The northwest is dominated by flat, poorly drained glacial lake plain soils—historically wetland systems that require careful stormwater and drainage design on development sites. Central Ohio around Columbus features dense, high-clay glacial till that drains poorly, compacts under construction traffic, and requires soil amendment strategies for successful planting establishment. The southeastern unglaciated plateau is characterized by steep terrain, shallow rocky soils, and erodible slopes. Each region calls for a different design approach, and our team has worked across all of them.
Ohio EPA Stormwater Requirements and NPDES Compliance
Construction site stormwater management in Ohio is governed by the Ohio EPA’s NPDES permit program. Development projects that disturb one or more acres require a permit, an approved stormwater pollution prevention plan, and design elements that manage post-construction runoff rates and water quality. Our landscape construction documents are produced in coordination with the civil engineer’s grading and drainage package to ensure that planting, mulching, and ground cover specifications align with the erosion and sediment control plan requirements. We are familiar with the Ohio EPA’s Rainwater and Land Development Manual and produce documents that satisfy its requirements.
Invasive Species Management
Ohio’s invasive plant species list includes several species that commonly appear on development sites—Callery pear, bush honeysuckle, garlic mustard, Japanese knotweed, and multiflora rose among them. The Ohio Department of Agriculture designates these as restricted or prohibited species, and their presence on a project site affects both tree disposition planning and long-term planting design. We identify invasive species issues early in the design process and incorporate removal, replacement, and long-term management strategies into our plans.
Municipal Landscape Code Variation
Ohio’s cities and counties maintain their own landscape ordinances, and they vary considerably. Columbus’s landscape code requirements differ from those in Dublin, Westerville, or Delaware County. Cincinnati’s zoning standards differ from Hamilton County’s. Cleveland Heights has its own zoning code requirements distinct from Cuyahoga County’s. We don’t assume one jurisdiction’s standards apply to another—we research the applicable code for every project and design to it from the first submittal.
South Florida Water Management District Permitting
The SFWMD Environmental Resource Permit (ERP) program governs stormwater management for development projects across Miami-Dade, Broward, and Palm Beach counties. For projects that involve significant impervious area, wetland impacts, or proximity to Biscayne Bay or the Everglades system, SFWMD coordination is a critical component of the design and permitting process. Our team has experience navigating SFWMD requirements and structuring landscape and drainage design to support efficient permit reviews.
Ohio Development Markets We Serve
Our Ohio landscape architecture practice is active across the state’s primary commercial, residential community, and industrial development corridors.
Columbus Metro — Ohio’s fastest-growing development market, with active residential community, mixed-use, commercial, and industrial development across Franklin, Delaware, Licking, Fairfield, Pickaway, and Union Counties. We work regularly in Dublin, Hilliard, Westerville, New Albany, Grove City, and the broader Columbus MSA.

Responsive and deadline-driven. Ohio’s development markets move quickly. Our clients count on us to deliver on schedule and respond promptly when questions come up during plan check or construction.
Frequently Asked Questions — Ohio Landscape Architecture
Yes. Our landscape architects are registered with the Ohio Landscape Architects Board and hold current Ohio licensure. We hold the Certificate of Authorization required for firms providing landscape architecture services in the state, carry professional liability coverage, and are fully bonded. We are authorized to serve as landscape architect of record on projects requiring a licensed professional seal across all Ohio jurisdictions.
Ohio’s combination of freeze-thaw climate, geologically variable soils, Ohio EPA stormwater requirements, and jurisdiction-by-jurisdiction municipal code variation creates a more complex design environment than many states. A hardscape design detail that works in Virginia or Georgia will fail in Columbus if it isn’t detailed for frost depth and freeze-thaw cycling. A planting design appropriate for Cincinnati’s milder Zone 6b climate needs adjustment for Cleveland’s Zone 6a conditions. We account for these distinctions on every project.
Both. Land planning is a core service we provide in Ohio alongside landscape architecture and irrigation design. Our land planners engage at the earliest stages of site development—working with civil engineers and developers to establish the site framework that shapes everything downstream.
We produce landscape and planting specifications that are coordinated with the project civil engineer’s SWPPP and grading plan. Ground cover, mulch, and planting specifications on disturbed areas must align with the erosion and sediment control commitments in the NPDES permit. We are familiar with the Ohio EPA’s Rainwater and Land Development Manual and produce documents that satisfy its requirements.
Yes. Design-build contractors are a significant part of our client base in Ohio and nationally. We understand the delivery model and structure our engagement—milestones, communication, and document deliverables—to support design-build schedules and coordination requirements.
We work across commercial, residential community, industrial, mixed-use, and civic project types. Common Ohio engagements include:
- Residential community landscape and irrigation packages for master-planned subdivisions
- Commercial site landscape and hardscape construction documents
- Industrial campus buffering and low-maintenance planting packages
- Land planning support for PUD and rezoning submittals
Yes. We work statewide, including in smaller cities, rural townships, and county jurisdictions. Development activity in Ohio extends well beyond Columbus and Cincinnati, and our team is comfortable coordinating with county and township planning authorities in less urbanized markets.
