To limit or eliminate the use of potable water or other natural surface or subsurface water resources available on or near the project site for landscape irrigation.
Reduce water consumption for outdoor landscape irrigation by 50% from a calculated baseline for the site’s peak watering month. Reductions may be attributed to any combination of the following strategies, among others:
- Plant species, plant density, and microclimate factor.
- Irrigation efficiency.
- Use of captured rainwater.
- Use of recycled wastewater.
- Use of water treated and conveyed by a government agency specifically for nonpotable uses.
- Use of other nonpotable water sources, such as stormwater, air-conditioning condensate, and foundation drain water.
Projects with no new or existing landscape irrigation requirements automatically meet the credit requirements.
Groundwater seepage that is pumped away from the immediate vicinity of buildings slabs and foundations can be used for landscape irrigation and meet the intent of this credit. However, it must be demonstrated that doing so does not affect site stormwater management systems.
