Total water withdrawal (potable and non-potable combined):

	Performance Year	Baseline Year
Total water withdrawal	1,759,300,000 Gallons	3,462,000,000 Gallons

Potable water use:

	Performance Year	Baseline Year
Potable water use	1,019,890,000 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 Period	Sept. 1, 2019	Aug. 31, 2020
Baseline Period	Sept. 1, 1990	Aug. 31, 1991

If end date of the baseline year/period is 2004 or earlier, provide:

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

The 1991 baseline represents the end of a relative flat usage trend 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 due to the improvements made beginning in 1991.

Figures needed to determine "Weighted Campus Users":

	Performance Year	Baseline Year
Number of students resident on-site	10,075	10,814
Number of employees resident on-site	235	172
Number of other individuals resident on-site	36	4
Total full-time equivalent student enrollment	60,416	41,171
Full-time equivalent of employees	9,051	7,000
Full-time equivalent of students enrolled exclusively in distance education	1,236	0
Weighted campus users	53,786.75	38,878.75

Potable water use per weighted campus user:

	Performance Year	Baseline Year
Potable water use per weighted campus user	18,961.73 Gallons	44,523.04 Gallons

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

57.41

Part 2. Reduction in potable water use per unit of floor area

Gross floor area of building space:

	Performance Year	Baseline Year

74.56

Part 3. Reduction in total water withdrawal per unit of vegetated grounds

Area of vegetated grounds:

	Performance Year	Baseline Year
Vegetated grounds	2,810 Acres	3,500 Acres

Total water withdrawal per unit of vegetated grounds:

	Performance Year	Baseline Year
