Sustainable Landscapes

Sustainable landscapes are an integral part of the broader concept of sustainability, focusing on creating and maintaining environments that are ecologically balanced and beneficial to communities. These landscapes are designed to be responsive to the environment, regenerative, and supportive of healthy communities. They aim to sequester carbon, purify air and water, improve energy efficiency, restore habitats, and provide economic, social, and environmental benefits.

Principles of Sustainable Landscapes

  1. Ecological Responsiveness: Sustainable landscapes are designed with a deep understanding of local ecology, aiming to enhance biodiversity and ecosystem services.

  2. Resource Efficiency: These landscapes prioritize the efficient use of resources, including water, energy, and materials. Techniques such as rainwater harvesting and solar energy utilization are commonly employed.

  3. Community Integration: Sustainable landscapes are often community-focused, providing spaces for recreation and social interaction, while also contributing to local economies.

  4. Climate Adaptation and Mitigation: By incorporating features that address climate change, such as carbon sequestration and flood management, sustainable landscapes play a crucial role in climate resilience.

Examples of Sustainable Landscapes

High Point, Seattle

High Point in Seattle is a mixed-income green community known for its natural drainage systems, complete streets, and allergen-free landscapes, which have significantly reduced local asthma rates.

Mount Tabor Middle School, Portland

In Portland, Oregon, the Mount Tabor Middle School campus features a 2,000 square foot rain garden that effectively cools classrooms and manages runoff, saving the city over $100,000 in potential sewer upgrades.

NE Siskiyou Green Street, Portland

Also in Portland, the NE Siskiyou Green Street uses planted curb extensions and check dams to manage stormwater, capturing and filtering 225,000 gallons annually.

Burbank Water and Power Eco-Campus, California

Located in California, the Burbank Water and Power Eco-Campus is a LEED Platinum certified sustainable utility featuring green roofs, streets, and a fully recycled water system.

Sunnylands Center & Gardens, California

Sunnylands, a LEED Gold desert landscape in California, incorporates native plants, stormwater retention, and a solar-powered, water-saving design.

Transformative Water, Pitkin County

In Pitkin County, Colorado, a polluted asphalt plant was transformed into a sustainable ranch with wetlands, water storage ponds, and wildlife habitat.

Sustainable Landscaping Techniques
  • Native Planting: Incorporating native species reduces water usage and supports local wildlife.
  • Xeriscaping: This technique minimizes or eliminates the need for irrigation.
  • Rain Gardens: These gardens collect and filter runoff, improving water quality.
  • Green Roofs: Vegetated roofs improve insulation and manage rainwater.
  • Permeable Pavements: Allow water to infiltrate rather than run off, reducing stormwater impacts.
