Dear Mr. Dorney,
SUBJECT: Proposed Improvements to Halstead Boulevard,
Pasquotank County; Federal Aid No. STP-1152(4); State
Project No. 8.2110201; TIP No. U-3449; DWQ Project No. 011595.
Please reference the 401 Water Quality Certification for DWQ Project No. 011595 issued
on January 9, 2002. The 401 certification approved the NCDOT's construction plans for
Transportation Improvement Program project U-3449. The project involves the
extension of Halstead Blvd. In Elizabeth City, North Carolina.
At the time the original 401 Water Quality Certification was issued, the plans called for a
temporary work bridge to accommodate equipment during the building of the permanent
bridge structure. Subsequent to the project being let to construction,the contractor
submitted a value engineering proposal to use top down construction rather than build a
temporary work bridge. However, the new proposal will necessitate a minor change in
the bridge design.
The currently permitted design calls for seven interior bents and eight poured in place
spans. Each interior bent has twelve 20.0-inch square piles for a total of 84 piles. The
total area of the piles is 233.43 square feet. The currently designed spans are
approximately 88.0 feet long.
The new proposal will have twelve interior bents, each with twelve 24.0-inch square
piles. Due to the limitations of span lengths on top down construction, each new span
will be 52 feet-four inches long. The increased number and size of the piles will increase
the total area of the piles from 233.42 square feet to 576.0 square feet. The new proposal
will eliminate the need for approximately 150 steel pile piles that would have been used
to support the temporary work bridge.

Additionally, the NCDOT proposes to clear 15.0 feet on each side of the new structure in
order to provide a clear work area to operate cranes and other equipment. This action
does not increase the amount of cleared area above that which would have been cleared to
construct the temporary work bridge. The cleared area will remain approximately 0.47
acres.
The NCDOT hereby requests that the 401 Water Quality Certification be modified to
reflect the changes described above. This action has been approved by the USACE
through a Memorandum for the Record and by the North Carolina Division of Coastal
Management through a letter of refinement. Copies of the memorandum for the record
and the letter of refinement are included for reference. A check in the amount of$200.00
is included to cover the processing fee.
If you have any questions, or need additional information, please contact Mr. Lindsey
Riddick at [phone] extension 304.
