Level of ”Physical Risk QUANTITY” for the institution’s main campus as indicated by the World Resources Institute’s Aqueduct Water Risk Atlas:
Low

Total water use (potable and non-potable combined):
Performance Year Baseline Year
Total water use 1,505,081,000 Gallons 3,462,000,000 Gallons

Potable water use:
Performance Year Baseline Year
Potable water use 645,430,000 Gallons 1,731,000,000 Gallons

Start and end dates of the performance year and baseline year (or three-year periods):
Start Date End Date
Performance Year Sept. 1, 2015 Aug. 31, 2016
Baseline Year Sept. 1, 1990 Aug. 31, 1991

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

The 1991 baseline has been the university benchmark due to the extremely high water usage during that period. It also represents the end of a relative flat usage tend when water conservation measures were being considered and instituted. The water use trend has been downward since even with the increase in enrollment and occupied square footage on the campus.
