Subject: Modification request for alternate layout of the oyster structures. CAMA Major
Permit No. 78-22, TIP No. M-0540A NC 24 Resiliency and Living Shoreline Project.
WBS No. 49083.3.1

Reference: Action ID No. SAW-2020-00406, NCDWR Project No. 20210539

Dear Mr. Lane,

The N.C. Department of Transportation, Division 3, is requesting a modification to the
above referenced permit for proposed changes to the type and layout of the oyster
structures. The proposed changes are being requested due to the depth of the water on the
west end and far east end of the project (approximately -2.5 ' to -3.5'). The attached plan
modification sheet summarizes the requested changes.

The changes include:
• “Table-top” style oyster structures will be used in lieu of the “cantilevered” style
oyster structures which were depicted in the original permit drawings. The “table-
top” oyster structures will be interlocked, as shown and called-out in the attached
specification sheet.
• The oyster structure area enumerated in the wetland and surface water impacts
summary table will be decreased from 0.10 acre to 0.09 acre (see attached revised
wetland and surface water impacts summary table sheet).
• Oyster structures OR1, OR2, OR3, OR4, and a portion of oyster structures OR5 and
OR9 will be not be installed due to the water depth at the west end and the far east
end of the project. Oyster structures OR5, OR6, OR7, OR8, and OR9 will have an
increased width to 12' wide (the length of these structures is the same as originally
proposed for OR6, OR7, and OR8, but shortened to 40' and 45' resp ectively for

OR5 and OR9). Oyster structures OR-A and OR-B (which were not originally
depicted in the permit drawings) will be added landward of two closure sills. They
will each be 12' wide by 75' long. No additional surface water impacts for OR-A
and OR-B is needed as they will be placed within an area which is already
permanently impacted and accounted for as fill.
The Department of Transportation acknowledges that the WBS element noted in the
subject line can be debited for fees for this modification.
Please let me know if any additional information is needed in support of this request.
