Optional Fields

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

In FY22 we recalibrated all the irrigation systems to run only twice per week rather than every other day as was normal for many years. This was pursued due to recent water restrictions from the City of Brookings. We maintain an open line of communication with the city and are happy to reduce watering on campus by 30%. This initiative will continue even in the absence of water restrictions.

Data source(s) and notes about the submission:

Performance year data is a three year average from FY20, FY21, and FY22. A three year average was also used for the weighted campus user statistics, which is why this number is different than PRE 5.

SDSU develops storm water Best Management Practice areas wherever feasible on the SDSU campus to help slow, clean, and divert stormwater project on the east side of campus to help address the high velocity water discharged from the City of Brookings through the main campus as overland flow. These areas function as sustainable wildlife or insect habitat
