Subject Comments on Divisions 1 2 and 3Wetland and On Site Mitigation Monitoring Reports for 2008
This office has reviewed the Wetland and On Site Mitigation Monitoring Reports for 2008 for NCDOT
Divisions 1 2 and 3 The DWQ offers the following comments based on review of the aforementioned
documents
Division 1
B 1303 Roanoke River Overflow Mitigation Site — This site appears to be doing well and is exceeding the
minimum success criteria The DWQ recommends the NCDOT continue to monitor this site
B 3348 Kitty Creek and Wallace Canal — This site was treated for phragmrtes prior to the site being
completed Due to the nature of phragmrtes it is suggested that the NCDOT keep a very close eye on
this site to ensure that it doesn t re emerge and cause future problems It is possible that an infestation
of phragmrtes could cause the site to not meet jurisdictional status The site appears to be doing well
the DWQ recommends the NCDOT continue to monitor this site
B 3858 Lake Landing Canal — The constructed stream channel appears to be stabilized The DWQ does not
object to discontinuing the monitoring at this site
R 2548AE US 64 Bypass Temporary Impact Sites — The natural vegetation appear to be re establishing
itself The DWQ recommends the NCDOT continue monitoring the site
R 2548C Scuppernong Mitigation Site — As suggested the DWQ recommends the NCDOT replant the
previously mowed areas and take efforts to ensure that it doesn t get mowed in the future
Additionally the DWQ recommends the NCDOT continue monitoring the site
R 2548E US 64 Bypass Mitigation Site This site appears to be doing well and is exceeding the minimum
success criteria The DWQ recommends the NCDOT continue to monitor this site
K 4003 Roanoke Island Mitigation Site —This site has presented many issues since being established in
2002 The NCDOT conducted a field meeting with the appropriate' resource agencies and is following
the recommendations from this meeting Also phragmrtes has been a documented problem at this site
and has recently been treated It is suggested that the NCDOT continue to monitor for any phragmrtes

recommended that the NCDOT continue to monitor this site
B -4271 Big Swamp Mitigation Site — The NCDOT is encouraged to closely monitor areas after revegetation
to ensure that there are no underlying issues that may prevent the site from obtaining jurisdictional
status It is recommended that the NCDOT continue to monitor this site

R 2633CA US 17 Wilmington Bypass Temporary Impacts Site — The report should state when the site was
planted It is recommended that the NCDOT continue to monitor this site
U 0092AB Smith Creek Mitigation Site — The DWQ has several concerns regarding the status of this site
The DWQ is concerned about invasive species that have been reported at this site Phragmites has
been an issue with this site since the 2007 monitoring report and in October 2008 the site was treated
for kudzu The phragmites based on Table 3 3B has gotten much worse with several monitoring plots
containing a very large fraction of phragmites There was some discussion in 2007 between the DWQ
USACE DCM and Division 3 about possibly treating for phragmites but to the DWQ s knowledge
this has not yet happened The DWQ is also concerned about the bald cypress that has been planted In
the 2007 report the average density was reported to be 67 trees /acre in the 2008 report densities had
declined to 39 trees /acre Rather than discontinuing monitoring the DWQ encourages the NCDOT to
schedule a meeting possibly a field meeting with the appropriate agencies to further discuss the fate
of this site The DWQ does not feel it can agree to discontinue monitoring of the site at this time
U 0092AB Smith Creek Parkway Temporary Impact Sites — The NCDOT is proposing to discontinue
monitoring at these sites The NCDOT is in the process of closing out this mitigation site and proper
coordination with the resource agencies should continue as necessary
U 0092WM County Mitigation Site — With respect to bald cypress this site appears to be doing better than
the adjacent Smith Creek Site Before the DWQ can agree to discontinue monitoring of this site the
NCDOT is respectfully reminded that an on site meeting with the appropriate regulatory agencies will
be required
U 0092 AB Wastewater Treatment Mitigation Site — According to the report the site must obtain 70
percent coverage of target species Currently it is at 63 percent which is below the 70 percent
required Consequently the 2007 report indicates that coverage was at 63 percent as well indicating
that the site is not improving towards the 70 percent coverage goal The DWQ recommends that the
site be monitored for one more year to see if the required 70 percent can be obtained If the required 70
percent coverage cannot be obtained then the NCDOT should schedule a meeting with the necessary
resource agencies to discuss the fate of this site
U 0092A Third Street Bridge Mitigation Site — The shrubs planted at this site have not been successful As
a result the overall planting success of this site has been compromised and is below the minimum
requirement of 320 trees /shrubs at the end of year three If the NCDOT continues to work with the site
in order to try and get the site to meet full success criteria monitoring beyond five years may be
required If success criteria for the shrubs and /or the hardwood area cannot be met in a reasonable
length of time then appropriate mitigation credits may need to be acquired by other means
