B-2938 Stella Bridge Mitigation Site -This site appears to be doing well and meeting success criteria.
The NCDOT wants to discontinue vegetation and hydrological monitoring at this site after four years
of monitoring. The DWQ does not object to discontinuing hydrologic monitoring. The vegetation
appeazs to be doing well. The DWQ would like to visit the site before agreeing to discontinue the
vegetation monitoring.

to have met the minimum criteria. The NCDOT has expressed a desire to discontinue monitoring at .
this site. The NCDOT is respectfully reminded that an on-site meeting with the appropriate agencies
will be needed in order for the DWQ to approve close-out.
U-0092A Third Street Bridge Mitigation Site (New Hanover County) -The third year report was
generated in 2008. There does not appear to be a fourth year report from 2009 included on the
website. There have been some vegetation issues associated with this site in the past, which appear
to be ongoing. The DWQ is interested to, see if the issues at this site have improved. If they have not,
then it is suggested that the NCDOT consider other options to replace the required mitigation
associated with the construction of Smith Creek Parkway. If necessary, potential options will need to.•
be discussed with the appropriate resource agencies for approval. Resource agency staff visited the ..
site on April 29, 2009 and it was agreed that the hydrologic monitoring could cease.
