Data source(s) and notes about the submission:
For the area of vegetated grounds, we removed the footprint of buildings and non-vegetated surfaces, the area used to grow feed crops, and the experimental agricultural lands. We included the Student Farm because that 23 acre parcel is in Central Campus and actively used for student and public engagement, even though it is also used for food production.
The Davis campus potable water quantity is less than the total water quantity because the campus uses non-potable groundwater for landscape irrigation, as well as recycled water from our wastewater treatment plant. UC Davis is a registered small water supplier and the campus provides ground and surface water supplies for campus uses.
UC Davis maintains a Water Action Plan, which will be updated once the campus completes a Water Systems Study, which is expected to be completed in spring 2020. The current plan may be accessed at:
