Oklahoma Landscape Architects
Oklahoma Landscape Architecture Firm — Built for Land Developers, Civil Engineers, and Architects
Evergreen Design Group’s Oklahoma landscape architects work exclusively with land developers, civil engineers, architects, and design-build contractors on projects across the state. Founded in 2005 and licensed nationally, our team provides land planning, planting design, hardscape design, and irrigation design for development projects throughout Oklahoma.
If you’re moving a development project forward in Oklahoma and need a landscape architecture firm that integrates cleanly into your team’s workflow, delivers permit-ready construction documents on schedule, and understands the state’s regulatory and environmental conditions, that’s exactly what we do.
Landscape Architecture Services We Provide in Oklahoma
We offer a complete range of landscape architecture services for development projects throughout Oklahoma. Whether your project requires a single deliverable or a full-scope engagement, we structure our services around your timeline and project requirements.
Land planning is typically the first engagement point for development teams. We work with civil engineers and developers during the entitlement and site planning phase to establish site organization, open space allocation, circulation, grading concepts, and regulatory compliance frameworks. Our land planning services in Oklahoma account for local zoning requirements, stormwater ordinances, and the environmental conditions that vary significantly between the state’s western plains and its eastern regions.
Our Oklahoma planting plans are developed for function and long-term performance — not just aesthetics. We select species suited to the state’s climate zones, soil conditions, and water availability, from drought-tolerant natives for western Oklahoma to the more moisture-tolerant palettes appropriate for Tulsa and the eastern corridor. Planting plans are coordinated with grading, drainage, and irrigation systems and delivered as permit-ready construction documents.
When a site has existing tree cover, a tree disposition plan documents the condition, location, and disposition of protected or significant trees — identifying what will be retained, relocated, or removed. These plans support entitlement applications and municipality review in Oklahoma jurisdictions that require tree preservation documentation as part of development approval.
For residential and mixed-use developments, community amenities are a meaningful differentiator in Oklahoma’s competitive development market. We design pool surrounds, clubhouse environments, fitness areas, tot lots, passive park zones, and multi-use courts — coordinating with civil teams on grading, utilities, and access to deliver amenity packages that are both marketable and constructable.
Hardscape design in Oklahoma has to perform. Temperature extremes, high winds, freeze-thaw cycles, and intense rainfall require material selections and structural detailing that hold up over time. We design plazas, pedestrian systems, retaining walls, trails, parking lot islands, and amenity areas with durability and constructability in mind — and coordinate closely with civil engineers to ensure grading, drainage, and utility integration are fully resolved.
Our irrigation design services in Oklahoma cover residential communities, commercial developments, and mixed-use projects. We produce hydraulic calculations, zone layouts, head specifications, and controller sequences that meet local water authority requirements and are sized for efficient, long-term performance. Irrigation plans are coordinated with planting and grading documents to ensure system design reflects actual site conditions.
Landscape Architecture in Oklahoma — What Your Team Needs to Know
Development teams choose Evergreen Design Group for Oklahoma projects for five reasons: state licensure, direct integration with your project team, single-source delivery across disciplines, national multi-state experience, and dependable on-schedule delivery. Here’s what that looks like in practice.
Climate Variability and Plant Selection
Oklahoma spans multiple climate zones, and the difference between a project in Woodward and a project in Muskogee is significant. Western Oklahoma is semi-arid — annual precipitation is low, soils are sandy, and drought-tolerant species are essential for sustainable long-term performance. Eastern Oklahoma receives considerably more rainfall, features heavier clay soils, and supports a broader planting palette.
Our landscape architects understand these regional differences and design accordingly — ensuring plant selections, irrigation system sizing, and drainage approaches are appropriate for the specific site location, not generic to the state as a whole.
Stormwater, Drainage, and DEQ Compliance
Development projects in Oklahoma are subject to ODEQ (Oklahoma Department of Environmental Quality) stormwater permitting requirements as well as city and county-level drainage ordinances that vary by municipality. Our land planning and landscape architecture services are developed with these requirements in mind.
We coordinate directly with civil engineers of record on grading, retention, and bioswale integration — ensuring our design documents support permit submissions rather than create conflicts with the civil package.
Severe Weather Design Considerations
Tornado activity, high sustained winds, temperature swings, and periodic severe drought are conditions Oklahoma landscape architects have to design around — not just acknowledge. Our design approach addresses these realities through:
- Plant selections with demonstrated wind and drought tolerance
- Hardscape material and joint detailing appropriate for freeze-thaw exposure
- Planting and grading strategies that reduce erosion risk on exposed sites
- Irrigation systems designed for efficiency under variable precipitation conditions
Soil Conditions and Site Adaptability
Soil conditions vary significantly across Oklahoma — from expansive clay soils in the central and eastern regions to sandy loam in the west. These differences affect planting success, drainage performance, and hardscape subgrade requirements. We incorporate soil conditions into every phase of design, coordinating with geotechnical and civil teams when subsurface data is available.
Oklahoma Project Types We Support
We regularly provide landscape architecture services for the following project types in Oklahoma:
Residential Communities — Master-planned communities, single-family subdivisions, and for-rent communities requiring land planning, planting design, amenity packages, and irrigation systems.
Commercial Developments — Retail centers, office campuses, and mixed-use projects requiring site landscaping, pedestrian systems, stormwater integration, and parking lot planting.
Civic and Institutional Projects — Municipal facilities, educational campuses, and public parks requiring compliant, durable landscape design.
Industrial Sites — Distribution centers, manufacturing facilities, and logistics parks requiring perimeter planting, security-compatible landscape, stormwater compliance, and low-maintenance design.
Design-Build Projects — Contractor-led projects where the landscape architecture scope needs to be developed, documented, and permitted quickly without sacrificing accuracy or coordination quality.
Why Oklahoma Development Teams Work With Evergreen Design Group
Oklahoma’s geography, climate, and regulatory environment create a set of conditions that have a direct impact on landscape architecture scope, design approach, and project timeline. Here’s how we account for the factors that matter most on Oklahoma development projects.
Licensed Landscape Architects in Oklahoma
Evergreen Design Group's landscape architects are licensed in Oklahoma. We understand the state's regulatory environment, municipality-specific requirements, and the environmental conditions that vary across its distinct regions.
Integrated with Your Project Team
We don't work in isolation. Our landscape architecture services are designed to integrate directly with civil engineers, architects, and project managers. We coordinate on program management for multi-phase developments, grading, utilities, drainage, and permitting — and we communicate proactively so your team always knows where design stands.
Single-Source Delivery Across All Landscape Disciplines
Land planning, planting, hardscape, irrigation, amenities, and tree disposition — when you need more than one service, we deliver them as a coordinated package. One point of contact. Consistent documentation standards. Coordinated schedules. That matters on projects where multiple consultants need to work in parallel.
National Firm, Oklahoma Experience
Founded in 2005, Evergreen Design Group has delivered projects across the country for 20+ years. That national experience — combined with state-specific licensing and regional knowledge — means we bring a broad range of project types and solutions to every Oklahoma engagement.
Responsive, On-Schedule Delivery
Development timelines don't have slack built in. We treat schedule commitments as non-negotiable and communicate immediately if anything affects delivery. Our clients don't chase us for updates — we keep them informed throughout the process.
Frequently Asked Questions — Oklahoma Landscape Architects
Is Evergreen Design Group licensed to practice landscape architecture in Oklahoma?
Yes. Evergreen Design Group’s landscape architects are licensed in Oklahoma. We provide land planning, planting design, hardscape design, and irrigation design services across the state, and our construction documents are prepared to meet Oklahoma’s permitting and regulatory requirements.
Oklahoma Chapter of the American Society of Landscape Architects
What types of projects do you typically handle in Oklahoma?
We work on residential communities, commercial developments, mixed-use projects, industrial sites, and civic facilities. Our clients are land developers, civil engineers, architects, and design-build contractors — we don’t take on individual homeowner projects.
Can you coordinate directly with our civil engineer on grading and drainage?
Yes — that’s a standard part of how we work. Our landscape architecture documents are designed to align with the civil package, and we coordinate directly with engineers of record on grading, drainage, utility conflicts, and stormwater requirements throughout the design process.
Do you handle both land planning and construction documents, or just one phase?
We can engage at any phase. Some clients bring us in during entitlement for land planning support. Others engage us for construction document production once a plan is approved. We’re also structured to handle full-scope engagements from initial planning through permit submission and construction oversight.
How does your firm handle the climate differences between western and eastern Oklahoma?
We design to site-specific conditions, not state averages. A project in Enid requires a different plant palette, irrigation sizing, and drainage approach than a project in Tulsa. Our landscape architects account for regional precipitation, soil type, temperature exposure, and wind conditions when developing designs — and we discuss those variables with your team upfront.
What information do you need to provide a scope and fee proposal?
Typically we need a project location, an overall site acreage, a general description of the project type and program (e.g., 300-unit residential community with pool amenity), and your anticipated schedule. If you have a site plan or civil base, sharing that helps us scope more precisely. Contact us to start the conversation.
How does Evergreen Design Group price landscape architecture services for Oklahoma projects — flat fee, hourly, or percentage of construction cost?
Fee structure depends on project scope and phase. Land planning and entitlement support are typically scoped as a flat fee tied to defined deliverables. Full construction document packages are usually proposed as a lump sum based on site acreage and project complexity, with hourly rates reserved for open-ended coordination or revision work outside the original scope. We provide a written fee proposal before any engagement begins, so your team knows the cost structure upfront.
Can Evergreen Design Group support our Oklahoma RFQ or RFP submission with qualifications and past project experience?
Yes. We regularly provide qualifications packages, project experience summaries, and team resumes for RFQ and RFP submissions on Oklahoma developments. As a nationally licensed firm founded in 2005, we can supply relevant multi-state project experience alongside our Oklahoma licensure to support your submission requirements.
