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:
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.

Data source(s) and notes about the submission:
The baseline period for UCSC tracks the annual average over three years from July 2002-June 2005. Baseline year for Gross Floor Area of Building Space is 2003, the most relevant data available that aligns with one year of the 3-year water baseline period.
