No, these items are not needed for the contraction of the site.

10. The low hanging power / communication line leading into the project location will be taken care of prior to the start of construction by others we are to base that we will be able to transport basic over the road construction equipment based on 13'6" height restrictions by 10'6 access into the construction site.

Talbot County will address and low hanging lines that may be blocking access.
