In response to increasing drought restrictions from the City of Pasadena and the worsening water shortages across the southwestern United States, Caltech will no longer be irrigating non-functional turf as of July 18, 2022. All functional turf including athletic fields, event spaces, and common gathering areas will continue receiving biweekly irrigation as permitted under current drought restrictions. All campus tree canopy and native landscaping will continue to receive irrigation, as well.
A map of areas that will no longer be irrigated is available here. This change will save an estimated 5 million gallons of water per year and further contributes to Caltech's ongoing efforts to reduce campus water use. More details on these efforts can be found on the Caltech Sustainability website.
