A brief description of when and why the water use baseline was adopted:

We used calendar year 2014 and 2015 due to best capture the water saving measures implemented by Cal State LA in response to the recent severe drought conditions in California and Governor Brown's Executive Order B-29-15.

Water recycled/reused on campus, performance year:
0 Gallons

Recycled/reused water withdrawn from off-campus sources, performance year:
0 Gallons

A brief description of any water recovery and reuse systems employed by the institution:

A brief description of any water metering and management systems employed by the institution:

A brief description of any building retrofit practices employed by the institution, e.g. to install high efficiency plumbing fixtures and fittings:

Last year, Cal State LA replaced 150 toilets (3.6 gpf to to 1.28 gpf) in housing, and another 100 toilets and 50 urinals (1.2 gpf to 0.125 gpf) campus-wide. Estimated 450 remaining toilet and 300 remaining urinal retrofits to save an estimated total of over 10 million gallons per year. Cal State LA has also installed faucet aerators and low flow showerheads throughout campus.

A brief description of any policies or programs employed by the institution to replace appliances, equipment and systems with water-efficient alternatives:

A brief description of any water-efficient landscape design practices employed by the institution (e.g. xeriscaping):

Currently reducing campus lawns by approximately 20,000 SF with estimated water savings of 1 million gallons annually. Including climate appropriate low-water plants, permeable surfaces, and replacing existing irrigation systems with low-flow drip systems throughout campus.

A brief description of any weather-informed irrigation technologies employed by the institution:

Currently using Water2Save's wireless weather-based irrigation control system to adjust the amount of water applied to landscape, saving over 200 million gallons of water since 2009.

A brief description of other water conservation and efficiency strategies employed by the institution:

Cal State LA has also reduced watering of all campus lawns from 3 to 1 times per week, with the amount of watering time reduced from 20 to 8 minutes. We've also ended regular washing of exterior infrastructure, stopped washing main campus pathways, decks and parking garage on a monthly basis, and discontinued annual window washings. We've substituted exterior power washing methods with dry sweeping and area spot cleaning also ended washing of sports facilities, including tennis courts and stadium seating, before all matches.
