Thanks, Jonathan. The rubble mound portion of the groin is 750' long and I presume the contractor will
cover the the portion of the groin that ties into the seaward -most end of the beach fill. The beach fill
ends at roughly Sta. 9+50 on the structure... so, to answer your question, we are looking at covering
—650' of the rubble mound structure.

I see no issues, Brad. Whats the linear feet of the groin to be covered?

Subject: [Non-DoD Source] OIB terminal groin fill

Good morning Mickey and Heather (and Jonathan who may be sitting in for Heather this week!),
If you recall, several thousand cubic yards of the beach fill at 0113 was stockpiled just west of the terminal
groin in order to give the contractor a bit of space as they complete the rubble mound component of the
structure. Now that they have completed several hundred feet of the seaward -most portion of the
groin, they would like to go ahead and tie in some of that stockpiled material to the groin, as called for in
the permitted plan. Since there is an excess amount of stockpiled material, the contractor plans on
spreading the remaining material to an elevation of —+7' NAVD88 along the berm west of the structure
rather than the original +6 NAVD88 elevation (we already discussed this and you both gave the okay).
Because the elevation of the structure is +4.9' NAVD88 and the berm just to the west of the structure
will be +7' NAVD88, I wanted to check in to make sure that there would be no objections to having the
contractor cover the groin with this fill (as depicted in the hand -drawn figure below). The original plan
had the +6' NAVD88 berm being feathered into the groin. By extending the +7' NAVD88 berm across the
groin, we feel that this will actually help jump-start the sand bypassing over/through the groin which
would help achieve the goal associated with artificially filling the fillet in the first place. As you can see in
the drawing, the material would be pushed along the top of the groin and the material would be allowed
to fall off the western side at it's natural angle of repose. Please let me know if this is amenable so we
can give the contractor the green light to start pushing this sand atop the structure very soon.
Jonathan- if you are fielding this one while Heather is out and need a bit more context, just give me a call
any time!
Thanks you both,
Brad

I just realized that I had the wrong date on the "before" photo on the second page of the attached...
it should be September 14, 2021 (not March 18, 2022). 1 corrected that and re -attached here.
Sorry for the confusion.

Subject: CIB terminal groin sediment transport
Good morning all,
Now that the fill at 01B has been in place for a few weeks (dredged ended on March 12) and the
rubble mound portion of the groin is very close to being completed, it is interesting to see that
sediment has continued to flow to the east of the structure, as intended. This rate of transport will
most likely become reduced once the "leaky" groin fills with more sand and once the fill to the west
reaches an equilibrium, but I thought it was worth passing a few images along that depict the fact
that the down drift area is indeed still receiving material towards the inlet- see attached images from
March 18th and March 29th to see how the intertidal flat to the east of the structure continues to
grow. The second page of the attached PDF gives a good overall "before" and "after" depiction of
the project area as well. Just thought you all may be interested to see this...
