Subject: Request for Additional Information for T.I.P. B-4635 (Replacement of Bridge 9 over
South River Overflow on US 13, Sampson County)
Dear Sir and Madam:
Below are responses to needed additional information and corrections to previously submitted items for
the permit application for B-4635 (Replacement of Bridge 9 over South River Overflow on US 13,
Sampson County)
- the Corps ID assigned to this project is SAW-2015-01191. Comment noted and will be included where
appropriate.
- a PJD has been completed for this project therefore please upload this document with the PCN. Please
see the attached PJD.
- please upload the final SEPA/NEPA final approval letter. Not typically required.
- whereas this is not the main run of the River it still represents a stream channel, therefore please
correct the stream impact table accordingly, note TB falls water ward of the OHWM. Drawings have
been revised to remove wetlands from open water areas.
- 2h states there are no streams on site, the PJD shows approximate channels for the South River and
South River overflow. Permit drawings have been revised to depict how the PJD map shows the area.
- along the north side of the project where permanent fill is called for HC is noted. Within Division 3, MC
has always been requested along the slopes of permanent fill. This has been confirmed with Division
please correct throughout the package. If less than 10' of fill 5' of MC is appropriate and greater than a
10' fill height 10' has been the standard. Permit drawings have been revised.
- In E2c - the statement if DWR requires compensatory mitigation - if impacts less than 1 acre DWR does
not require mitigation (as it is 0.77 acres now, no mitigation will be required but if additional regulated
activity occurs (MC) and the cumulative total exceeds 1 acre mitigation would be required). DOT
proposes to mitigate at 2:1 for 0.53 acre of permanent wetland impact (fill and excavation) due to the
bridge replacement.. See last bullet for additional information about hand clearing.
-no topo or soils map in the application. Not typically required.
-county not identified in application form. Confirmed with DWR, it was on the original form.
- no discussion exists concerning the construction of the temporary impacts, no discussion regarding the
steps taken to support the temp fill thus avoiding long term compaction impacts, no recovery,
replanting and or monitoring discussed. The temporary fill at Sites WE and WF is associated with the on -

site detour. The temporary fill will be underlain with geotextile fabric and, when removed, the area of
impact will be restored to preconstruction slope and contours. The area will also be reforested with
appropriate tree/sapling species. No grubbing will occur within either the temporary impact or hand
clearing areas.
-there is no slope listed in the cross section drawings regarding the temp detour which leads to the
question, could the slope be steeper than 3:1 since it would most likely be constructed with a rock base
thus reducing the amount of temporary impact? Cross sections of the detour are included in revised
drawings to show 2:1 slopes along the detour.
-currently there is greater than 1 acre of hand clearing for utility line movement which should require
mitigation. There reads a statement that not all of the HC would occur in forested areas but it needs to
be noted how much forested wetlands would be permanently converted. If this amounts exceeds 0.5
acres the Department would be expected to provide mitigation for this conversion impact. Hand
clearing impacts in forested wetlands will exceed 0.5 ac. DOT proposes to reduce the hand clearing
impact of 0.99 acre with the reforested area (0.51) totaling 0.48 acre. The 0.48 acre of hand clearing
impact would be mitigated at 1/2:1.
