Which surfaces are excluded from outdoor water use reduction calculations?

The correct choice specifies non-vegetated surfaces as being excluded from outdoor water use reduction calculations. This means that areas such as pathways, paved surfaces, and other hardscape elements do not contribute to the calculation of water use for irrigation or landscape management. The intent behind excluding non-vegetated surfaces lies in the focus on promoting sustainable landscaping practices that minimize water consumption.

In calculating outdoor water use reductions, the emphasis is on irrigation needs for vegetated areas that require water to thrive, while non-vegetated surfaces naturally do not necessitate irrigation, allowing for a more accurate assessment of water use for the parts of the landscape that actively need it.

Vegetated areas, all turf areas, and soil and mulch beds, on the other hand, are included in calculations since they can be dependent on irrigation and water management practices to maintain their health and appearance. By concentrating on areas that require water, projects can target reductions more effectively, thereby enhancing environmental sustainability.
