Re: Refinement Major Permit#32-02
Dear Mr. Gilmore:
This letter of refinement is in reference to a request from Mr. Clay Willis, Environmental
Officer with Division One of the NC Department of Transportation. The request is for a •
refinement of CAMA Major Development Permit No. 32-02 issued to NCDOT on March 18,
2002. The permit was issued for the construction of a 52' x 682' bridge over a 100' wide
tributary to Knobbs Creek and associated wetlands located 3/10 mile north of US 17
Business/Halstead Boulevard intersection. The approved plat included a 25' wide temporary
work bridge with seven 25' x 64' fingers.
NCDOT has requested that two changes be authorized. The first is that top down
construction be used to construct the bridge thereby allowing the elimination of the temporary
work bridge from the project design. The addition of 60 piles is requested in order to shorten the
spans and allow top down construction. The additional piles will permanently impact 342
square-feet of wetlands. The number of pilings in the channel of Knobbs Creek will remain the
same (only one bent).
The second change involves the relocation of 0.47 acres of approved temporary wetland
impacts. It is requested that authorization be granted for the temporary clearing by hand (no
grubbing) of 15 feet of wetlands on either side of the permanent bridge to facilitate construction.
Instead of 30 feet of clearing on one side of the permanent bridge, 15. feet of clearing is proposed
on both sides of the bridge.
Your request to modify Permit #32-02 to include the aforementioned changes is hereby
authorized. Please be aware of the in-water work moratorium from February 15 to June 30 of
any year without the prior approval of DCM in consultation with NCDMF and NCWRC. All
permit conditions including the December 31, 2005 expiration date still apply and remain
unchanged. The permit as refined does not eliminate the need to obtain any additional state,
federal or local permits, approvals or authorizations that may be required, including any

necessary modifications to the 401 Water Quality Certification and the Nationwide Permit issued
by the Army Corps of Engineers.
The modification request and the modification drawings which were faxed to our office
on July 12, 2002 will become a part of the permit and construction should be carried out
accordingly.

REMARKS: ❑ Urgent ❑ For your review ❑ Reply ASAP ❑ Please Comment
Ed,
Included In this fax is the proposal that was sent to us from the contractor that is building the
bridge. He outlines the differences of the previous bridge and construction method and the new
proposal for the bridge and construction method.
It is my position that the new proposal is better from a environmental stand point and a
economical stand point. We hope we can proceed with this change.
Lindsey Riddick spoke to Cathy 6rittingham yesterday about the details of the proposal. She
indicated to Lindsey that if we only clear 15 feet on either side of the bridge then DCM could
make the revision by a letter of refinement. This seems appropiate given the circumstances. If
NCDOT is held up for 30-60 days for a permit modification. It might be more beneficial to
NCDOT to go ahead with the current permitted plans. This will result in more environmental
damage and increase the cost by$200,000.00.
If you have any questions about it, please give me a call at 252-482-7977 or Lindsey
Riddick at 919-733-7844 ext. 304

PREL1MrNARY VALUE ENGINEERING PROPOSAL
Project No. 6.2110201 Pdsquotank County, N.C.
We would like to request that the NCDOT consider our PreGminory Vdiue
Engineering Proposal to change the bridge as designed at station 638+112.00 on
the above referenced proiecl,The present design details a substructure
N-i/ — consisting of seven interior bents, each containing twelve. 20" square concrete
piles.The superstructure consists of eight poured In place spans. Each span is
supported on eight lines of 54" concrete girders appruomotety 88' long. Also
included in the present design Is a temporary wank bridge to allow access into
the wetlands for construction activitles,
We would like to propose a top-down constructed ooncrete cored slab bridge.
We hove included conceptual drawings to illustrate the type of structure we
propose. Generally, the substructure would consist of twelve interior bents. Each
11Fw bent would Incorporate tweeve, 24" concrete/ HP I 2x 53 steel composite pile
sections, The superstruCture would consist of thirteen spans of l '-9" x 3'-0" cored
sio Os, Each span would be 52'-4" long and be twenty-three slabs wide.This type
of construction would allow us to odvance ourselves into the wetlands utilizing
the new structure, thus eliminating the need for a temporary work tridge.
As with any proposed change In design or construction methods there are
advantages and disadvantages that need to be Considered. At this point we
would like to list the pros and cons that we see with our proposed design and
method.
ADVANTAGES
1. The need for a temporary wart bridge would be eiiminated.This would
result in the reduction of c7ppraximalely 150 steel piling to be driver and
extracted and ciso lessens the amount of wetland area that needs to be
grubbed for pile installation.
2. The amount of time that the wetland area will be exposed to construction
activity will be reduced from approximately 24 months to 9 months.
3. The depth of the superstructure we are proposing is oppropmatery 3' less
than Me one currently designed. If grade line elevations ara held the
some this will give an additional 3' of under cledronce for wafer passage.
The bottom of End Sent I will be 16'' below the normal water suria0e 'f
built as designed currently. Our method will raise the bottom of End Bent 1
20" above the normal water surface and also move the reinforced earth
fill out of the water tone.The additional under clearance also allows
additional sunlight t0 reach the wetlands bottom.

Engineering Proposal is approved we will be handling the redesign in house.We
feel that this is to our advantage as outside consulting fees would be eliminated
and we will remain In control of the timing.we will be working with the NCDOT to
explore other ideas that may result in additional monetary savings.
In summary. we feel that the advantages we hove outlined for exceed the
disadvantages. We feel that our proposal is much more environmentally friendly.
The NCDOT and subsequently the taxpayers will realize monetary savings both
now and in r+edueed future maintenance costs. And as the contractor,we
should be able to see reduced costs by being able to do the volume ci work in a
shorter period of time.
Respectfully Submitted,
Sanford Contractors,Inc.

Mike, John, David and Sara - please let Ed Harrell know ASAP if the following proposal by DOT
is unacceptable, or if additional conditions are needed. Thanks.
Hi Ed,
From what I understand, DOT is proposing two changes to the project as currently permitted:
1. The Contractor would like to construct the 682-foot long bridge using top down construction.
Therefore, the contractor would like to eliminate the temporary work bridge from the project
design. The use of top down construction will require that approximately 60 additional piles are
added to the bridge design. Therefore,there will be approximately 342 square feet of additional
permanent impacts to wetlands. The number of pilings in the channel of Knobbs Creek will not
change (there will be only one piling in Knobbs Creek itself.)
2. The Contractor would like to temporarily clear approximately 15 feet of wetlands on either side of
the permanent bridge to facilitate construction. This would result in approximately 0.46 acres of
temporary wetland impacts. In accordance with the 401 Water Quality Certification, all clearing
activities will be performed by hand. There shall be no grubbing. The current permit authorizes
0.47 acres of temporary impacts due to clearing a 30 foot wide area on one side of the bridge for
installation of the temporary work bridge. Therefore, the amount of temporary wetland impacts
will not increase, although the location of those wetland impacts will change. (Instead of 30 feet
of clearing on one side of the permanent bridge, there will be 15 feet of clearing on both sides of
the permanent bridge.)
In my opinion,this activity can be authorized under a Letter of Refinement with the standard
conditions. I would request that the Letter of Refinement include a reminder of the in-water work
moratorium from February 15 to June 30 of any year without the prior approval of DCM in consultation
with DMF and WRC. I would also request that the Letter of Refinement include a note stating that:
