Marks Creek Mitigation Site
ONEID 092-011
The Marks Creek Mitigation Site is located in Wake County within the USGS hydrologic unit
03020201 of the Neuse River. NCDOT acquired the 66 acre site to mitigate for unavoidable,
jurisdictional impacts associated with TIP R-2547. Monitoring requirements were performed from
2004 to 2008 and the site was closed out in 2009. Table 1 shows the final mitigation quantities
approved for the site. The site has been placed on the NCDOT On-site Debit Ledger for use within
HUC 03020201. Tables 2-5 indicate all mitigation debits that have occurred per regulatory agency
approval.
To offset unavoidable buffer impacts associated with T.I.P. B-5656, the Marks Creek Mitigation
Site will be debited 5322 square feet of buffer restoration. This debit is reflected in the debit
ledger below.
