Please Note: This document includes all individualy inventoried trees as of June, 2022 to
illustrate tree unit retention compliance on the property. This DOES NOT include all trees,
such as those marked as "grove of trees" in the current inventory, nor all the trees that are
in the large forested area surrounding the wetland and stream associat ed with this parcel;
this is NOT an exhaustive inventory. Some tree sizes may be undervalued and there may
be some errors due to work performed by other companies. Regardless of the potential
errors, this inventory underestimates the actual tree units on t he property as not all
forested areas are completely inventoried.
