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

Medium to High

Part 1

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

	Performance Year	Baseline Year
Total water use	281,771,175 Gallons	281,771,175 Gallons

Potable water use:

	Performance Year	Baseline Year
Potable water use	281,771,175 Gallons	281,771,175 Gallons

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

	Start Date	End Date
Performance Year	Jan. 1, 2017	Dec. 31, 2017
Baseline Year	Jan. 1, 2016	Dec. 31, 2016

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:

Before 2018 we did not have sufficient data to satisfy this category. We now have the ability to get accurate data in regards to all water used, (Excluding Irrigation) but do not have a way to segregate system makeup water.

Figures needed to determine "Weighted Campus Users":

	Performance Year	Baseline Year
Number of students resident on-site	2,800	2,800
Number of employees resident on-site	0	0
Number of other individuals resident on-site and/or staffed hospital beds	0	0
Total full-time equivalent student enrollment	18,441	18,441
Full-time equivalent of employees (staff + faculty)	1,713	1,713
Full-time equivalent of students enrolled exclusively in distance education	1,876	1,876
Weighted campus users	14,408.50	14,408.50

Potable water use per weighted campus user:

	Performance Year	Baseline Year
Potable water use per weighted campus user	19,555.90 Gallons	19,555.90 Gallons

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

Part 2

Gross floor area of building space:

	Performance Year	Baseline Year
Gross floor area	3,594,917 Gross square feet	3,594,917 Gross square feet

Potable water use per unit of floor area:

	Performance Year	Baseline Year
Potable water use per unit of floor area	78.38 Gallons per square foot	78.38 Gallons per square foot

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

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	138 Acres	138 Acres

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

	Performance Year	Baseline Year
Total water use per unit of vegetated grounds	2,041,820.11 Gallons per acre	2,041,820.11 Gallons per acre

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

Optional Fields

A brief description of the institution's water-related behavior change initiatives, e.g. initiatives to shift individual attitudes and practices such as signage and competitions:

The campus does a lot of xeriscaping in the new/renovated areas on campus. The plants thrive in desert like ecosystems and are more efficient for water use.

A brief description of the institution's water recovery and reuse initiatives:

Not applicable at this time.

A brief description of the institution's initiatives to replace plumbing fixtures, fittings, appliances, equipment, and systems with water-efficient alternatives (e.g. building retrofits):

All equipment associated with all systems gets replaced by high efficient replacements.
