FAQs about WEc1 :

Can non-potable well water that is used for irrigation contribute to potable water reduction?

Can surface water, such as water from an irrigation ditch or a local creek, be used as nonpotable water?

Do interior planters count in the calculation?

We are using non-potable water for irrigation. For drought conditions, can we hook up to a potable water source for backup and still earn this credit?

NC-2009 WEc1:Water Efficient Landscaping

What areas to include for planted areas?

We have a project where only about 1/3 of the planted area will be irrigated. The other 2/3 is planted with plants and groundcover that will not require irrigation. Do we just include the SF of irrigated planted area in the credit or do we include all SF of planted area to calculate the credit for potable water reduction?

Lauren - you'll need to include the entire landscaped area. As you fill out the form, you'll select the option for "The landscaping and irrigation systems have been designed to reduce irrigation water consumption from a calculated baseline case." and separate out by row based on landscape type and whether it's irrigated or not so you can account for the difference in the design case. The baseline case will reflect 100% irrigated. The design case will reflect the 33% irrigated. Hope that helps! Karin
