Michael Ellison (Director of the DMS) has earlier today provided approval of the required revisions. These revisions have resulted in some significant changes to the hydraulic design at Bridge 910132 near Stations 20+00 to 24+00 Lt/Rt. The attached file: Bridge 910132 and Rogers Road (SR 2052) Drainage Revision Narrative provides a comprehensive review of these hydraulic design revisions. Note also attached REVISED FINAL stream and riparian buffer permit drawing package for the entire project. It appears that there is no increase to jurisdictional impacts previously noted for the project in the February 4, 2016 permit application. Please contact me if you need additional information.

The NCDENR-DWR issued certifications for the project on March 4, 2016. Two construction issues have come up at this time. Note the following: Issue at Site 1(Bridge near 21+00 -L-) A portion of the project limits at the bridge is located within the Smith Austin Creek Mitigation Site and this use requires coordination with the North Carolina Interagency Review Team. An existing rock cross vane installed as part of the mitigation site is located directly at the outlet of proposed standard v ditches upstream of the bridge. The Department proposes "field-set and integrate" the ditches to the existing rock cross vane. Specifically, the ditches will be shifted as necessary to be slightly upstream of the top of the rock cross vane to provide at least 2 feet of separation between the low point of the proposed ditches and the top of the rock cross vane. This solution will integrate the proposed ditches and rock vane together, creating the most stable long-term solution.

We were under the understanding this 5.0' max cover applied under the roadway, but according to Pomona Pipes (delegate designer of the culvert) it also applies on the shoulder. As currently designed there is approximately 5.7' of fill at the right shoulder point. To reduce the fill, we are proposing to raise the downstream invert 1 foot to the natural channel bed elevation. The invert at the outlet will be set to match the adjacent downstream elevation. A mix of Class B and Class I rip rap will be installed in the a slight blow hole (i.e. countersunk) in the streambed below the outlet. The upstream invert would remain buried 1 foot and a one foot sill would be placed at the upstream face (slightly inset inside the culvert). A mix of Class B and Class I rip rap will be installed in the streambed (i.e. countersunk) up to the top of sill. The countersunk rip rap in the streambed at the inlet and outlet of the culvert is fully within the previously permitted stream improvements. 3 ■s■■E ■�■■� �w�■� ��iiiE ��0��1�E��l��i ■■■�■iiw■�RF .*.�■■� � �+• � 5��7_1+�� .aEi�� :4� ■■■■■1�■■■� wJr�' w��:�� ■■��■ ■■■■■1�■■�� ■■■ri■■'. �■� i■■�r� �i■■ ■■■■■l�■■�J■■■■■■f�l�l■■■■■■■i #■■■ C��At�■L' �■ ■■■■■■■I E�■ ■■■■■■� 1■!� i�,�.�►:� �'■f 1■■■■■■f��:�■■■■■■■L11►:►� ■iit�l��t:�.?�L' �■■■■■■■�I�r■■■■■■■N'Jl�:w: ■■■��:�:* �i� �■■��■�I�i: ■A■�� r;:�l ■■■■■�l3� '��..r�`ar ��;a�� ■.�.i� ��iir.i�.iR�Rv.��.ir.ira�.�� r.��a�.�r.��ti�.w�.�_�i�� ■■■■■��i■■■■■■■■■■■■■■■■■■■17■■ y��i��■� I�■■■■L]■■■��■■■ .r I■■�■■�I■�7■■■�!i �1 I■■■■�11■�■■■■■■:'1 I■■■■il�ll�■■■■■■■� � I■■■■'�i�f.^i� ■■■■■■a � I■■■■r�R�■■■■■■■■.
