Challenges Faced by Landscape Architects in Oklahoma

Regulatory Complexity & Stormwater Management

Projects often must comply with Oklahoma Department of Environmental Quality (DEQ) standards and city-level stormwater ordinances. Landscape architects must design effective runoff controls, retention basins, and erosion-resistant systems.

Severe Weather & Tornado Activity

 Designs in Oklahoma must account for:

  • Wind damage mitigation through planting strategies
  • Temperature extremes and intense rainfall
  • Reinforced hardscapes for long-term durability

Soil Variation & Erosion Control

  • Sandy soils in the west and heavy clay in the east require adaptive planting and drainage design
  • Erosion-prone sites demand native vegetation and slope stabilization

Balancing Urban Growth & Natural Character

  • Integration of native plants and open spaces in new developments
  • Maintaining Oklahoma’s scenic identity while supporting urban expansion

What to Expect from a Landscape Architect in Oklahoma

Following an initial consultation and site evaluation, your Evergreen Design Group landscape architect customizes the design approach based on context and goals. Below are examples of how our services come into play:

Residential Development Projects

  • Outdoor living zones: patios, fire pits, pergolas
  • Privacy buffers, screening planting, and fences
  • Plant palette of drought- and frost-tolerant species
  • Efficient irrigation systems built to local standards
  • Hardscape features built to withstand freeze-thaw cycles

Commercial Projects

  • Public plazas, courtyards, landscaped walkways
  • Stormwater and bioswale systems built to municipal specs
  • Wayfinding and sidewalk integration
  • Shaded seating areas and outdoor amenity zones
  • Lighting and landscape coordination for safety and ambiance

Industrial Projects

  • Perimeter planting with low-maintenance species
  • Compliance with erosion control, clean stormwater runoff, and site grading

Throughout, we leverage land planning strategies, integrate tree disposition plans where trees must be relocated or retained, implement thoughtful planting designs, and engineer efficient irrigation systems.
