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

High

Part 1

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

	Performance Year	Baseline Year
Total water use	---	206,235,408 Gallons

Potable water use:

	Performance Year	Baseline Year
Potable water use	190,142,191 Gallons	180,509,726 Gallons

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

	Start Date	End Date
Performance Year	July 1, 2015	June 30, 2016
Baseline Year	June 1, 2004	July 30, 2005

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:

2005 was the year we've used in past reports. We don not have solid numbers for the 2005 "Vegetated grounds" acreage. We imputed a conservative estimate.

Figures needed to determine "Weighted Campus Users":

	Performance Year	Baseline Year
Number of students resident on-site	7,733	6,053
Number of employees resident on-site	34	15
Number of other individuals resident on-site and/or staffed hospital beds	1	0
Total full-time equivalent student enrollment	28,657	12,523
Full-time equivalent of employees (staff + faculty)	3,185	2,202
Full-time equivalent of students enrolled exclusively in distance education	7,464	4,104
Weighted campus users	20,226.25	9,482.75

Potable water use per weighted campus user:

	Performance Year	Baseline Year
Potable water use per weighted campus user	9,400.76 Gallons	19,035.59 Gallons

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

50.61

Part 2

Gross floor area of building space:

	Performance Year	Baseline Year
Gross floor area	6,879,949 Gross square feet	4,498,861 Gross square feet

Potable water use per unit of floor area:

	Performance Year	Baseline Year
Potable water use per unit of floor area	27.64 Gallons per square foot	40.12 Gallons per square foot

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

31.12

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	405.68 Acres	380 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	542,724.76 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:

Every water bottle refill station has an education sign on it designed by students. The Eco-Reps (sustainability liaisons in each resident hall) dedicate at least one month a year to water conservation

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

The University taps into the City of Flagstaff's reclaimed water system for the majority of its landscaping irrigation and some of its toilet water usage.

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):

Most of campus water fixtures were changed out in 2012. Low flow toilets, shower heads and aerators were installed and are now our campus standard.
