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 | --- | 70,004,323 Gallons |
Potable water use:
| Performance Year | Baseline Year | |
| Potable water use | 25,974,674 Gallons | 24,694,472 Gallons |
Start and end dates of the performance year and baseline year (or three-year periods):
| Start Date | End Date | |
| Performance Year | June 1, 2015 | July 30, 2017 |
| Baseline Year | July 1, 2007 | June 30, 2010 |
A brief description of when and why the water use baseline was adopted:
The baseline period (July 2007 to June 2010) is a three year period in order to average out year-over-year variation. The same three year baseline period is used for all calculations requiring a baseline except when data is unavailable.
Figures needed to determine "Weighted Campus Users":
| Performance Year | Baseline Year | |
| Number of students resident on-site | 434 | 377 |
| Number of employees resident on-site | 6 | 6 |
| Number of other individuals resident on-site and/or staffed hospital beds | 11 | 3 |
| Total full-time equivalent student enrollment | 450 | 383 |
| Full-time equivalent of employees (staff + faculty) | 210 | 158 |
| Full-time equivalent of students enrolled exclusively in distance education | 0 | 0 |
| Weighted campus users | 616 | 504.50 |
Potable water use per weighted campus user:
| Performance Year | Baseline Year | |
| Potable water use per weighted campus user | 42,166.68 Gallons | 48,948.41 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 | 1,046,473 Gross Square Feet | 734,680 Gross Square Feet |
Potable water use per unit of floor area:
| Performance Year | Baseline Year | |
| Potable water use per unit of floor area | 24.82 Gallons / GSF | 33.61 Gallons / GSF |
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 | 46.70 Acres | 51.20 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 / Acre | 1,367,271.93 Gallons / 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:
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):
SUA's irrigation system was recently upgraded with brass-valve "smart" sprinklers that review evapotranspiration and only deploy when moisture has evaporated from the soil. Plastic drip irrigation valves were also replaced with brass valves to prevent leakage. The Olympic-sized pool has a cover that reduces water evaporation rates. Finally, aerators have are being installed on all sinks across campus.

Additional documentation to support the submission:
Vegetated area data were calculated using ESRI's ArcGIS. Between the baseline and performance years, vegetated area decreased due to the construction of Maathai Hall and the Soka Performing Arts Center, the expansion of Parking Lot A, and the construction of the parking structure adjacent to the Recreation Center.
