Subject: RE: B-5804, Brantley Road over Lake Fisher, Cabarrus Co., permitting questions
Jim,
Here are my views of these issues:
1) Given the presence of overhead power lines on one side of the bridge and an adjacent aerial water line on the
other side, dewatering in the location of the proposed end bents is not feasible during construction (work in the
dry would not be possible during the removal of the existing end bents, installation of proposed end bents, and
bank stabilization of the steep slopes). The Design Build team would like to use turbidity curtains here to
contain sediment. They have checked with NCDOT's Roadside Environmental Unit,who has agreed that this
approach makes sense. Sediment would not likely travel far from the project site since this is not a flowing
channel. Is this an acceptable approach for this work?
- DWR understands the constraints and is alright with this proposal. We would ask that the curtains be
inspected regularly and after each significant weather event to make sure that they remain in good order
and are maintained in an appropriate way. Also,we would request that during construction the areas
outside of the curtains be monitored (visually usually suffices)to make sure that no turbidity escapes and
causes a water quality violation. If there is evidence that turbidity is leaving the containment area,work
should be stopped immediately until the situation can be remedied. Without dewatering it does, however,
complicate removal of the existing bridge with respect to any debris that may fall in the water during bridge
removal. So,we would ask that they be especially careful not to drop debris in the lake during bridge
removal and with the use of wet concrete during construction. There have been numerous other instances,
especially on the coast with longer bridges,where the area could not be dewatered and turbidity curtains
were used instead.
2) The project impacts will be less than %acre, so we anticipate this project being permitted under a Nationwide
Permit(NWP). At this point, it appears that the impacts will only be surface water impacts to the lake, including
permanent fill,temporary fill, and bank stabilization. Which permit type would you anticipate being required for
these types of impacts?The reason for asking is that we have had other bridge replacement projects in the past
with similar impacts permitted under a GP 31; NWPs 3 and 13; NWPs 23,33, and 13; and, recently, a NWP 14.
Parsons was inquiring to make sure they applied for the appropriate permit(s) in their PCN.
I can't answer this one. As you know, these calls are made by the USACE and DWR issues the corresponding
certification.
3) Since only open water impacts and no wetland or stream impacts will occur, the current plan is to submit the
Preliminary JD Request with the permit application. Is this acceptable, or should we submit the JD request prior?
- Under the circumstances, I don't object.
4) Do USACE or DWR have any concerns regarding the loss of volume in the reservoir from fill placed in the lake or
is that primarily an issue to be discussed with the municipalities? The City of Concord has already indicated it is
not concerned.
I don't have any concerns. Given the size of the lake and the relatively miniscule amount of fill to be added, I
don't see where it would affect water quality, stormwater treatment, or flow through the lake enough to
make a difference.
If you have any other concerns or questions, please let me know.

Subject: B-5804, Brantley Road over Lake Fisher, Cabarrus Co., permitting questions
Crystal and David-
Parsons Brinckerhoff is currently working on the design for B-5804, which is the proposed bridge replacement on
Brantley Rd. over Lake Fisher.This is being contracted under the same Design Build contract as 1-3802A. However, it will
have its own CE separate from 1-3802A. After having a conversation with Adam Karagosian at Parsons earlier this week, a
few design/permitting concerns/questions came up that I wanted to ask you about.The concerns/questions are as
follows:
1) Given the presence of overhead power lines on one side of the bridge and an adjacent aerial water line on the
other side, dewatering in the location of the proposed end bents is not feasible during construction (work in the
dry would not be possible during the removal of the existing end bents, installation of proposed end bents, and
bank stabilization of the steep slopes). The Design Build team would like to use turbidity curtains here to
contain sediment. They have checked with NCDOT's Roadside Environmental Unit,who has agreed that this

If you could email me back when you have an opportunity it would be much appreciated.
Thanks,
Jim
