Sustainable design benefits GSA with healthier, longer

fertilizers, minimize water use, require less maintenance
and increase erosion control.
General Design Principles
Sustainable landscape design considers the characteristics
of the site and soil, and the intended effect and use of
the developed area, in addition to the selection of plants.
Where appropriate, regionally-native plants will be used.
Zoning or grouping by plant materials may be considered
if an irrigation system is to be used. Refer to the seven
