Please Note: The initial construction was completed in January 2022, and the MY0/As-built report was submitted in April 2022. Wildlands (WEI) realized a wetland grading error occurred
at this point and notified the IRT and DMS of this problem. At the August 9, 2022, IRT Meeting, WEI provided an overview of the issue and requested approval to regrade these areas
to the approved Mitigation Plan specifications. The regrading work was completed in October 2022, revised as-built in November 2022 and replanting of disturbed areas occurred in February
2023. The MY0/As-built report has been updated to reflect the regrading effort. Other than the wetland regrading areas, several structures were added, deleted or had materials substituted
during construction/final design based on site conditions and material availability. These changes are shown as redlines and are discussed in Section 2.1 of the report. Other than
the minor changes to structures, there were no alignment deviations, and the project was constructed as designed.
