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	---	88,179,476 Gallons

Potable water use:

	Performance Year	Baseline Year
Potable water use	84,000,400 Gallons	88,179,476 Gallons

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

	Start Date	End Date
Performance Year	July 1, 2017	June 30, 2018
Baseline Year	July 1, 2013	June 30, 2014

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:

Water use baseline year 2013-2014 was chosen to coincide with the Cal State East Bay's initial Greenhouse Gas Inventory.

Figures needed to determine "Weighted Campus Users":

	Performance Year	Baseline Year
Number of students resident on-site	1,562	1,457
Number of employees resident on-site	5	0
Number of other individuals resident on-site and/or staffed hospital beds	2	0
Total full-time equivalent student enrollment	13,735	13,369
Full-time equivalent of employees (staff + faculty)	1,894	1,346
Full-time equivalent of students enrolled exclusively in distance education	0	0
Weighted campus users	12,115.50	11,400.50

Potable water use per weighted campus user:

	Performance Year	Baseline Year
Potable water use per weighted campus user	6,933.30 Gallons	7,734.70 Gallons

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

10.36

Part 2

Gross floor area of building space:

	Performance Year	Baseline Year
Gross floor area	2,011,416 Gross square feet	1,987,306 Gross square feet

Potable water use per unit of floor area:

	Performance Year	Baseline Year

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:

Cal State East Bay stopped watering 12 turf areas on campus. These areas have signage indicating the campus is saving water by stopping irrigation. Additional signage to promote water conservation is posted in restrooms throughout campus.

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

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):

Replacing bathroom fixtures that meet Water Sense criteria including low-flow aerator heads.

Data source(s) and notes about the submission:

Weighted Campus User in performance year for OP 22 differs from IC 3, because IC 3 indicates the current year as the performance year (AY18/19) and OP 22 indicates performance year for AY17/18 in alignment with most current dataset available when this credit criteria was completed.
