Subject: Excavation at Thorofare Bridge
Good afternoon Mickey and Joanne,
Attached are workplan drawings of the MCAS Cherry Point's Thorofare Bridge property showing
the modifications I made (in red) requesting the excavation of approximately 1720 square feet
or 95.6 cubic yards of material from the man-made canal adjacent to our existing docking
facility. There are three drawings in total which include a plan view, a typical profile of
the area to be excavated, and an older drawing indicating the originally authorized depth
(The drawings are numbered 1 of 4, 3 of 4, and 4 of 4. I created a close-up of the plan view
(2 of 4) to submit to DCM for the CCD modification). We are requesting to excavate to - 3
ft. below nlw. The spoil material will be dewatered at the location indicated on the workplan
drawing behind a silt fence (at least) and will be at least 30 feet from the nhw in all
directions. After dewatering, the spoil material will be hauled off by the contractor to an
approved upland sight. No wetland or shellfish beds will be filled or excavated.
Mickey, I have attached the Individual Permit form per your request. If you would need it
for any reason, the Action ID number associated with the previously authorized actions at
this location is 2009-00644. I am correct in understanding that you need me to send you a
hard copy of this information as well?
Joanne, the action ID associated with DWQ's authorization of this project is
09 0291. We are requesting a modification to this authorization to allow for the excavation.
Do you need me to send you hard copies and a narrative as well, or will this email suffice?
Thank you very much for your help in this matter and let me know if you have any questions.
Look forward to talking to both of you soon,
v/r
