ASIDE FROM ADDING beauty to landscapes, trees perform several vital functions. They help stabilize soils, absorb rainwater and reduce the velocity and volume of rainwater hitting concrete and other impervious surfaces. They provide shade, especially on south and west façades; in the dry climate of the Southwest, for example, a shade tree can lower temperatures by up to 20 degrees. Trees also block wind, especially when planted near north façades. And they capture and store carbon.

NATURAL LANDSCAPES naturally slow the movement of stormwater, and capture and filter some of it as it percolates back into the groundwater supply. But the built environment is dominated by impervious surfaces. Paved surfaces, roofs and building façades change the movement of water over the landscape and increase the volume, speed and temperature of the runoff. Rushing stormwater picks up pollutants, fertilizers and pesticides and can also cause flooding and erosion.

GRAYWATER IS USED household water that has not come into contact with toilet wastewater. It represents two-thirds of a typical household’s indoor water budget. Reusing graywater to irrigate landscaping keeps it onsite and conserves potable water, easing the burden on both water treatment and wastewater treatment plants. Unfortunately, state regulations have made legal use of graywater difficult, if not impossible—although that is changing.
