A brief description of when and why the water use baseline was adopted:

Fiscal Year 2014 is the earliest year that we have been able to compile actual water use data for both the Danforth and School of Medicine Campuses.

Figures needed to determine "Weighted Campus Users":

	Performance Year	Baseline Year
