FAQs about WEc3 :

Can I still use Option 1 if I have metered irrigation water use data but it’s only for a couple of months or not the whole irrigation season?

The site already uses reclaimed water for irrigation provided by the water utility or reuses graywater from the building for irrigation. Can the building still qualify for the credit?

To determine the baseline for Option 1, how can we determine what “conventional” practices are?

What if the building has no irrigation systems?

EBOM-2009 WEc3:Water Efficient Landscaping

Baseline landscape type

For a project where turf grass area is replaced by native low-irrigation demanding planting would baseline landscape type include turf whereas design type include the new water efficient species? Obviously, if this is allowed, a greater reduction in water use is achieved.

If a comparable development in the area would normally use turf, and you are utilizing a vegetation type that is more water efficient, it is perfectly acceptable to use turf in your baseline, and the more efficient plant material in your design case. The only requirements, per se, are that the total irrigated areas and the microclimate factor be consistent between the two cases. Keep in mind, the baseline case is defined as the typical development in the area. Your project can deviate completely from what is the norm, so it's not uncommon to have different vegetation between the two cases.
