Follow up
Completed
The Corps of Engineers received your Pre - Construction Notification (PCN) for the proposed Dunhill Subdivision
on May 23, 2014. However, your application is incomplete and cannot be processed until the following
information is received:
1. Please include a description describing how each permanent fill /culvert will be constructed under dry
conditions. Typically, in order to avoid and minimize impacts associated with the project, temporary fills are
utilized so that the permanent fills /culverts are constructed under dry conditions. If temporary impacts will be
necessary, please quantify these and include them on the proposed plans.
Please provide the proposed pipe length at each impact site and the proposed dissipation pad length at
each impact site.
3. In order to determine compliance with Nationwide Permit Condition #2 (Aquatic Life Movement) you must
provide additional information regarding the proposed dissipation pads. Specifically, you must indicate if the
top of the stone rip rap apron will be placed /constructed so that it is level with the receiving channel. If so,
please provide a profile view of each impact area indicating that the top of the stone is at the existing bed
elevation. If not, you will need to indicate how you plan to prevent the disruption of aquatic life movement.
You should also provide a written description of the placement of the rip rap dissipation pads.
4. The rip rap dissipation pad at impact area #1 appears to be aligned at such a sharp angle with the receiving
stream, that additional erosion of the downstream segment may occur. Please indicate how you plan to
prevent additional, downstream erosion at this location, or re- design the crossing to lessen the erosion
potential. If you redesign the crossing, please provide updated impacts associated with the redesign.
Please submit the above information within 30 days of receipt of this notification or we will consider your
application withdrawn and close the file. Please call or email me consider your application withdrawn and
close the file. Please call or email ( Andrew .E.Williams2 @usace.army.mil) if you have any questions.
