Heather/Josh,

Attached please find an updated set of drawings reflecting pre-construction conditions and the proposed construction template for Kitty Hawk. In accordance with Condition No. 14 of
the subject permit, an updated survey showing beach conditions was conducted by TI Coastal between May 25 and May 31, 2022. The updated survey data have been incorporated into the
attached drawings and cross sections. Please refer to the attached email last dated January 28, 2022, for additional context on our expectations as to how to satisfy this condition.
As previously discussed, and noted on the drawings submitted with our CAMA application, “The Seaward toe of beach fill line as shown, is not fixed and rather is subject to change based
on the conditions of the nearshore bathymetry at the time of construction”. For the purpose of comparison, we have included on the attached drawings the position of the seaward toe
of beach fill as shown on the original plans dated November 4, 2021 (green dashed line). On average, the proposed seaward toe of fill shown on the attached drawings is located landward
of the seaward toe of fill shown on the original permit drawings. There are some areas between baseline stations 162+00 and 153+00 as well as 63+00 and 25+00 that indicate a seaward
toe of fill slightly seaward of the seaward toe of fill shown on the permit drawings dated November 4, 2021.

Also shown on the updated plans attached is the location of the Mean High Water (MHW) line as observed on May 25 through May 31, 2022. This is in accordance with Condition No. 3 of
the permit. We will also provide this data as we did previously in a GIS Shapefile. That will be provided in a follow up email.

Please also note that the locations of the three (3) sublines proposed by Weeks Marine for Kitty Hawk are indicated on the attached drawings.

Lastly, as we’ve mentioned a couple of times, due to some dune losses that occurred in April 2022, we would like to get permission to repair some of the dunes to their pre-storm conditions.
The CAMA permit states in Condition 13 that: In accordance with commitments made by the permittee and to ensure compliance with Condition No. 12, the engineered dune shown on the original
plans is hereby eliminated except 2 remaining dune sections, located between Stations 185+50 and 190+80, and Stations 146+00 and 154+00, …”. No changes to the southern dune section
is being proposed (Station 185+50 to 190+80), but we would like to extend the northern dune section to cover the area between 165+00 and 145+00. Cross sections of the proposed dune
modifications are provided in the attached. The dune modification has been designed to comply with Condition 12 of the CAMA permit in terms of aligning the constructed dune with existing
adjacent dune ridges to the greatest extent possible, designing to the same configuration as the adjacent frontal dune, and adherence to the 3H:1V slope requirement along the oceanward
face.

We are requesting you review these updated plans in terms of the updated berm and toe of fill dimensions and approve assuming you find the plans in compliance with the subject permit.
Furthermore, we request you provide authorization to construct the dune along the additional location described herein with the understanding that the dunes will be constructed to
adhere with condition 12. Please note construction of the project is anticipated to begin in mid-July. If you would like to schedule another meeting to discuss the updated plans,
please let us know dates that would work for you. Also, please confirm receipt of this email. The PDF attachment was 20 Mb.
