MEMORANDUM
TO: James Bridges, NCDOT Bridge Project Planning Engineer
FROM: Mason Herndon, NC Division of Water Quality, Fayetteville Regional Office
SUBJECT: Scoping Review of NCDOT's Proposed Bridge Replacement Projects: B- 5303
(Duplin County),
In reply to your correspondence received via e -mail on December 21, 2012 in which you requested
comments for the above referenced project, the NC Division of Water Quality offers the following
comments:
Project - Specific Comments
B -5303, Bridge No. 45 over Island Creek on SR 1162, Duplin County
1. Island C reek is designated as C;Sw waters within the Cape Fear River Basin. Island Creek is
assigned Stream Index Number 18 -74 -27 and is on the 303d listings for Aquatic Life under
Category 3a (parameter assessment not rated due to insufficient or inconclusive data).
2. DWQ cannot comment on permit requirements with the limited information provided. Detailed field
delineation is required to determine the presence or absence of jurisdictional resources within the
project limits. In addition, NCDOT must provide an estimate of impacts to any resources located
within the construction limits of the project before we can specifically comment on DWQ permit
eligibility. j
3. Whenever possible, the DWQ prefers spanning structures. Spanning structures usually do not
require work within the stream or grubbing of the stream banks and do not require stream channel
realignment. The horizontal and vertical clearances provided by bridges allow for human and
wildlife passage beneath the structure, do not block fish passage and do not block navigation by
canoeists and boaters.
In most cases, the DWQ prefers the replacement of the existing structure at the same location with
road closure. If road closure is not feasible, a temporary detour shall be designed and located to
avoid wetland impacts, minimize the need for clearing and to avoid destabilizing stream banks. If
the structure will be on a new alignment, the old structure shall be removed and the approach fills
removed from the 100 -year floodplain. Approach fills shall be removed and restored to the natural
ground elevation. The area shall be stabilized with grass and planted with native tree species. Tall
fescue shall not be used in riparian areas.
