Level of ”Physical Risk QUANTITY” for the institution’s main campus as indicated by the World Resources Institute’s Aqueduct Water Risk Atlas:
Total water use (potable and non-potable combined):
| Performance Year | Baseline Year | |
| Total water use | --- | 57,575,958 Gallons |
Potable water use:
| Performance Year | Baseline Year | |
| Potable water use | 41,423,377 Gallons | 57,575,958 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 | July 1, 2012 | June 30, 2013 |
A brief description of when and why the water use baseline was adopted:
We are using 2012-13 as baseline year because California started mandated drought reductions based on usage for the year 2013; the academic year 2012-13 is the closest similar measure to this time frame.
Figures needed to determine "Weighted Campus Users":
| Performance Year | Baseline Year | |
| Number of students resident on-site | 2,047 | 2,013 |
| Number of employees resident on-site | 6 | 5 |
| Number of other individuals resident on-site and/or staffed hospital beds | 0 | 0 |
| Total full-time equivalent student enrollment | 8,228 | 7,618 |
| Full-time equivalent of employees (staff + faculty) | 1,284.80 | 1,168 |
| Full-time equivalent of students enrolled exclusively in distance education | 75.20 | 30.33 |
| Weighted campus users | 7,591.45 | 7,071.25 |
Potable water use per weighted campus user:
| Performance Year | Baseline Year | |
| Potable water use per weighted campus user | 5,456.58 Gallons | 8,142.26 Gallons |
Percentage reduction in potable water use per weighted campus user from baseline:
Gross floor area of building space:
| Performance Year | Baseline Year | |
| Gross floor area | 1,995,999 Gross square feet | 1,995,999 Gross square feet |
Potable water use per unit of floor area:
| Performance Year | Baseline Year | |
| Potable water use per unit of floor area | 20.75 Gallons per square foot | 28.85 Gallons per square foot |
Percentage reduction in potable water use per unit of floor area from baseline:
Does the institution wish to pursue Part 3 of this credit? (reductions in total water use per acre/hectare of vegetated grounds):
Area of vegetated grounds:
| Performance Year | Baseline Year | |
| Vegetated grounds | 614.79 Acres | 614.79 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 | 93,651.42 Gallons per acre |
Percentage reduction in total water use per unit of vegetated grounds from baseline:
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:
1. 95% of soap dispensers on-campus got "Soap on, water off" stickers to conserve water
2. Green Campus facilitates an annual water competition at the residence halls
3. Brown lawn area signs explaining the reductions in irrigation for non-essential areas to change expectations of aesthetics
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 (e.g. building retrofits):
In March 2014, Facilities Management began planning and implementing actions that would assist the campus in achieving a 20% mandated water reduction. Short-term items were completed within that calendar year and long-term items were slated for successive years, as funding was available.
Short-term strategies included:
1. Install aerators at sink faucets
2. Install low flow showerheads at Kinesiology & Athletics, Recreation & Wellness Center, BSS, Theatre Arts and Forestry Showers
3. Retrofit existing flushometers to reduce required water for flushing
4. Ensure all recirculation pumps are working properly and efficiently
5. Conduct domestic and irrigation water system leak detection survey
6. Implement campus education program
7. Manually reduce irrigation watering
8. Reduce water use by eliminating pressure washing in advance of major campus events (i.e. graduation)
9. replace water-cooled condensing unit at Forestry with air-cooled unit
Long term Strategies included:
10. Repair domestic & irrigation water system leaks per survey findings
11. install building and system level metering
12. Install soil moisture controlled irrigation system controllers including lines for programming
13. Install low flow fixtures (i.e. toilets, urinals, etc)
14. Install water storage system for greenhouse watering (student designed project)
15. Create campus user education program
16. Replace campus events fields with all weather turf

Data source(s) and notes about the submission:
-Number of residents on-site was calculated by utilizing the number of unduplicated students who lived in campus housing over the two terms.
-All campus water is potable water, just divided into two distribution systems for domestic use and irrigation, so this is why the total water and potable water quantities are the same.
