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

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	254,688,764 Gallons	337,287,590 Gallons

Potable water use:

	Performance Year	Baseline Year
Potable water use	204,174,080 Gallons	292,717,216 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, 1996	June 30, 1999

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:

The baseline was chosen to match the baseline chosen in UCSB's Water Action Plan, which was produced in accordance with baseline requirements set by the University of California, Office of the President. The 1996-99 baseline was the earliest point in which UCSB had complete water consumption data. A three-year period was selected to provide a snapshot of water consumption, rather than one year's worth of data--a single year could have been a dry or wet year, thereby distorting policy regarding water consumption.

Figures needed to determine "Weighted Campus Users":

	Performance Year	Baseline Year
Number of students resident on-site	7,414	4,002
Number of employees resident on-site	68	0
Number of other individuals resident on-site	0	0
Total full-time equivalent student enrollment	24,443	17,790
Full-time equivalent of employees	5,697	4,130
Full-time equivalent of students enrolled exclusively in distance education	4,213	246
Weighted campus users	21,315.75	17,256

Potable water use per weighted campus user:

	Performance Year	Baseline Year
Potable water use per weighted campus user	9,578.55 Gallons	16,963.21 Gallons

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

43.53

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

Gross floor area of building space:

	Performance Year	Baseline Year
Gross floor area	8,390,475 Gross square feet	4,725,563 Gross square feet

Potable water use per unit of floor area:

	Performance Year	Baseline Year
Potable water use per unit of floor area	24.33 Gallons per square foot	61.94 Gallons per square foot

Percentage reduction in potable water use per unit of floor area from baseline:

60.72

Part 3. Reduction in total water withdrawal per unit of vegetated grounds

Area of vegetated grounds:

	Performance Year	Baseline Year
Vegetated grounds	750 Acres	729.70 Acres

Total water withdrawal per unit of vegetated grounds:

	Performance Year	Baseline Year
Total water withdrawal per unit of vegetated grounds	339,585.02 Gallons per acre	462,227.75 Gallons per acre

Percentage reduction in total water withdrawal per unit of vegetated grounds from baseline:

26.53

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

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

UCSB partnered with Goleta Sanitary District to build a recycled water facility, which is located at the Sanitary District, close to the campus. The facility produces recycled water, which we then use to irrigate 90% of the landscape on the campus. We also use recycled water in the toilets located in all the restrooms of the lab wing in Bren Hall.The University expanded the recycled water line along UCen Road. This expansion allows landscapes that were previously irrigated with potable water to now use recycled water.

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

UCSB has made it a campus priority to update inefficient plumbing fixtures with high-efficiency fixtures, such as high-efficiency urinals, low-flow toilets, and new aerators on faucets. UCSB Facilities Management has received over $1,000,000 in grants and matched funding for retrofitting restrooms with efficient high-efficiency fixtures.
Additionally, the residence halls and dining commons have significantly improved their water conservation infrastructure in the past two years. Faucet aerators, high-efficiency shower heads (1.75 ga/minute) and dual-flush toilets (1.6/1.1 gallon per flush) have been installed in all of the residence halls. In the San Rafael residence hall, 100 new high efficiency toilets (1.28 gallons/flush) have been installed.
