Data source(s) and notes about the submission:
This represents FY2022 BU Metrics.
We have identified an inaccurate representation of "Area of vegetated grounds" in the past few submissions the acres from PRE-4 were applied to this value. We have updated this section based on the estimated values determine on the "Landscape Management" credit OP-9. In the coming years, BU will be able to have a more accurate assessment of its vegetated ground through its updated space management system.
