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 | --- | 206,700,000 Gallons |
Potable water use:
| Performance Year | Baseline Year | |
| Potable water use | 172,130,000 Gallons | 206,700,000 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, 2002 | June 30, 2005 |
A brief description of when and why the water use baseline was adopted:
This matches existing mandatory reporting requirements to our local municipality and UC Office of the President.

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:
The University engages the campus community through emails, flyers, as well as outreach through residential advisors and building contacts. We also have implemented an automated meter analytics system (Beacon Cellular Endpoint System) that uses cellular communication to track hourly usage, and a web based interface to allow students, staff, and faculty to understand their water consumption patterns.
A brief description of the institution's water recovery and reuse initiatives:
UCSC is in the design phase of two waste water treatment plants on campus.
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):
A Major Maintenance program retrofits buildings annually. A top priority of the program is to upgrade all plumbing fixtures to the highest efficiency technology available. High usage, inefficient fixtures are prioritized for Deferred Maintenance and Water Efficiency funding projects. The campus utilizes a Evapotranspiration irrigation system for watering major turf and landscape areas.
The Green Office Certification and Green Labs Program works to install aerators.
