Sustainable Residential Design: Using Low-Impact Materials
The landscape architect mined elements from the cannery structure, including abandoned machinery, for repurposing in the new gardens. The recycled tumbled glass riverbed in the Dining Room Court, and stone columns in the Lew Hing Garden add to the historic character. Hand crafted site furnishings made from FSC-certified wood, concrete, steel, and glass were designed by the landscape architect and crafted by Miller Company Landscape Architects’ in-house installation team.

New and non-recyclable materials used in homes and landscapes are often not designed to be recycled. These materials can consume enormous amounts of resources to produce and distribute and create additional waste when they are demolished. Waste materials create waste landscapes: landfills, massive incinerator systems, and multi-square-mile floating plastic garbage islands in the world's oceans.
To avoid sending useful materials to landfills and cut down on materials that release toxic substances, The Sustainable SITES Initiative™ (SITES®) recommends reusing or recycling existing materials.
Homeowners can also specify local materials to support local economies and cut down on the energy use from the transportation of materials.
But beyond reused, recycled, or local materials, there are other important ways to reduce the impact of materials on our health and environments.
Sustainable residential landscape design can increase the health of environment through the use of innovative low-impact materials that are permeable and reflective (high albedo).
Permeable materials allow water to infiltrate and recharge aquifers, instead of being sent to combined stormwater and sewer systems.
Reflective, "cool," or white materials help reduce air temperatures, particularly in cities dealing with the challenges of the urban heat island effect, and energy costs by minimizing the use of air conditioning to cool buildings.
There are also more sustainable wood and concrete options out there that minimize consumption of newer materials.
SITES recommends building with certified, sustainably-harvested woods, recycled woods, and recycled plastic or composite lumber to preserve forests, which are critical to sequestering greenhouse gas (GHG) emissions.
To avoid sending useful materials to the landfill, conserve natural resources, and reduce a project’s carbon footprint, SITES recommends landscape architects source sustainable concrete from manufacturers using supplementary cementing materials, like fly ash – a byproduct of coal-fired power plants. Landscape architects should reuse concrete from structures on the existing site, like crushed concrete as an aggregate base. Concrete that incorporates recycled materials, like crushed glass or wood chips, are a more sustainable and use less cement than traditional pavers.
Used in both landscapes and buildings, low-impact materials can reduce GHG emissions and create a healthier environment.
Local governments can partner with non-profit organizations and landscape architects and designers to increase public awareness about why it's important to use low-impact materials.
