Nice find UC, I couldn’t get google to spit the second one out yesterday.
Note, the first one is for new home construction targets, which are utilizing a number of water savings features inside and out.
The 60% irrigation is average across customers in all housing types (I assume since no clarification is provided).
So if the average is 60% and that is from a fairly typical cross section of housing in SD, I would assume a person with a 10,000SF lot would be far higher.
