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

FY2013 was the baseline selected for our first STARS submission in March 2018. At the time we selected a baseline year 5 years prior to the performance year and used that across credits. We are continuing to use this baseline to maintain consistency across submissions.

Figures needed to determine "Weighted Campus Users":

	Performance Year	Baseline Year
Number of students resident on-site	1,245.53	2,068
Number of employees resident on-site	14	20
Number of other individuals resident on-site	7	0
Total full-time equivalent student enrollment	1,833	2,068
Full-time equivalent of employees	682.30	737
Full-time equivalent of students enrolled exclusively in distance education	0	0
Weighted campus users	2,208.36	2,625.75

Potable water use per weighted campus user:

	Performance Year	Baseline Year
Potable water use per weighted campus user	52.11 Cubic meters	58.12 Cubic meters

Percentage reduction in potable water use per weighted campus user from baseline:

10.33

Vegetated grounds	254.95 Hectares	254.95 Hectares

Total water withdrawal per unit of vegetated grounds:

	Performance Year	Baseline Year

Data source(s) and notes about the submission:

We recognize that the data for this credit has been strongly impacted by the campus closure in mid-March 2020 due to the Covid-19 pandemic. We have decided to report on FY2020 for all of our credits to maintain consistency in reporting. We have seen a decline in water use since our baseline year, but we recognize that there were 3 months of much less water use than would be typical in this fiscal year.

The number of students resident onsite for our performance year (FY2020) was modified to take into account the campus closure on March 15 due to Covid 19. A weighted average was calculated assuming we had 1,699 students onsite for 29 weeks (August 26-March 15) and 50 students onsite for 11 weeks (March 15-May 30).
