All,
We've received the additional amounts of mechanized clearing needed for bent installation associated with
the bridges (5 & 6) at permit site 9. Attached are plans depicting trees the contractor has determined need to
be removed, warranting the additional mechanized clearing.
The total mechanized clearing for all stumps is 457 ft2 (0.0105 ac). This amount excludes any portion of a
stump that fell within the footprint of a cap.
To reach this total the amounts below were added:
• 2' to the diameter of any tree 8" and under
• 4' to any tree ranging from 9"- 24"
• 6' to any tree over 24"
Additionally, excavation in wetlands will be needed at both bridges for the installation of several bents due to
their proximity to the ground. This will require 836 ft2 (0.0192 ac) of excavation at bridge 5 and 280 ft2 (0.0064
ac) of excavation at bridge 6, bringing the total additional permanent impacts to 0.0361 ac. To perform this
excavation, the contractor will use temporary matting in wetlands which will require an additional 1,280
ft2 (0.0294 ac) of temporary fill.
The impact summary sheet has been revised to account for these additional impacts. We are requesting
approval via an in field modification from the USACE and NCDWR. Attached is an updated consistency
certification for NCDCM.
Due to the project currently being under construction, we request your respective agencies review this
revision as soon as possible. Thank you for your time and please let us know if you have any questions or need
any additional information.
