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

Medium to High

Part 1. Reduction in potable water use per person

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

	Performance Year	Baseline Year
Total water withdrawal	284,946,453 Gallons	284,946,453 Gallons

Potable water use:

	Performance Year	Baseline Year
Potable water use	281,985,199.74 Gallons	281,985,199.74 Gallons

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

	Start Date	End Date
Performance Period	July 1, 2019	June 30, 2020
Baseline Period	July 1, 2019	June 30, 2020

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:

Fiscal Year 2006-07 was the last full fiscal year before aggressive water conservation measures were implemented, such as automated weather-based irrigation controls and domestic water fixture retrofits to low-flow units. Irrigation well to supply roughly 40% of irrigation supply on main San Bernardino campus was also in operation effective November 2007. The year is used as a baseline to measure our improvement and performance with longitudinal research to identify trends and water behavior patterns.

Figures needed to determine "Weighted Campus Users":

	Performance Year	Baseline Year
Number of students resident on-site	183	1,294
Number of employees resident on-site	12	9
Number of other individuals resident on-site	0	0
Total full-time equivalent student enrollment	17,020	50,728
Full-time equivalent of employees	1,781.70	1,752
Full-time equivalent of students enrolled exclusively in distance education	428	329
Weighted campus users	13,829.03	39,439

Potable water use per weighted campus user:

	Performance Year	Baseline Year
Potable water use per weighted campus user	20,390.82 Gallons	7,149.91 Gallons

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

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

Optional Fields

A brief description of the institution's water-related behavior change initiatives:

CSU Executive Order 987 (2006), Section V.3.19. mandates that "all CSU campuses will take every necessary step to conserve water resources, including such steps as installing controls to optimize irrigation water, reducing water usage in restrooms and showers, and promoting the use of reclaimed water. The use of decorative fountains should be minimized. In the event of a declaration of drought, the CSU will cooperate with the state, city, and county governments to the greatest extent possible to effect additional water conservation."

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

None.

A brief description of the institution's initiatives to replace plumbing fixtures, fittings, appliances, equipment, and systems with water-efficient alternatives:

All domestic water fixtures, including sink faucets, shower heads, urinals, and toilets on both campuses have either been constructed as or now retrofit to low-flow units. State and some non-State buildings have automated motion sensors on sink faucets installed to minimize water waste while soaping and from unoccupied faucets left running.
