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

Low to Medium

Part 1

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

	Performance Year	Baseline Year
Total water use	---	67,017,046 Gallons

Potable water use:

	Performance Year	Baseline Year
Potable water use	40,227,440 Gallons	46,981,880 Gallons

Start and end dates of the performance year and baseline year (or three-year periods):

	Start Date	End Date
Performance Year	Jan. 1, 2015	Dec. 31, 2015
Baseline Year	Jan. 1, 2009	Dec. 31, 2009

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 baseline year was selected because it is after major renovations and building construction. The baseline year is recent enough to capture reliable data from the past and assess progress on sustainability efforts.

Figures needed to determine "Weighted Campus Users":

	Performance Year	Baseline Year
Number of students resident on-site	2,189	2,284
Number of employees resident on-site	11	10
Number of other individuals resident on-site and/or staffed hospital beds	18	0
Total full-time equivalent student enrollment	4,104	3,983
Full-time equivalent of employees (staff + faculty)	781	816
Full-time equivalent of students enrolled exclusively in distance education	13.90	0
Weighted campus users	4,221.33	4,172.75

Potable water use per weighted campus user:

	Performance Year	Baseline Year
Potable water use per weighted campus user	9,529.58 Gallons	11,259.21 Gallons

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

15.36

Part 2

Gross floor area of building space:

	Performance Year	Baseline Year
Gross floor area	2,263,247 Gross square feet	2,263,247 Gross square feet

Potable water use per unit of floor area:

	Performance Year	Baseline Year
Potable water use per unit of floor area	17.77 Gallons per square foot	20.76 Gallons per square foot

Percentage reduction in potable water use per unit of floor area from baseline:

14.38

Part 3

Does the institution wish to pursue Part 3 of this credit? (reductions in total water use per acre/hectare of vegetated grounds):

Yes

Area of vegetated grounds:

	Performance Year	Baseline Year
Vegetated grounds	292 Acres	316 Acres

Total water use (potable + non-potable) per unit of vegetated grounds:

	Performance Year	Baseline Year
Total water use per unit of vegetated grounds	0 Gallons per acre	212,079.26 Gallons per acre

Percentage reduction in total water use per unit of vegetated grounds from baseline:
