FYI ... they have just added 6000' of dune from 920+00 south and have bumped up the elevation to
12' NAVD and out to a width of 40'. Haiqing just emailed back that even with the change, it will
remain within the permitted 4mcy volume.
They are planning on starting up with the dredging with the Ellis next Tuesday and estimate the
Liberty will show up around the 12th or 13th
Please let me know if you have any questions or concerns.

Thanks Haiqing,
Can you please also send updated plan view drawings showing the new design (with MHW shown as
well)? And can you also please tell me how this changes the excavation volume? Will it exceed 4mcy
now or are you still under that volume?

Hi Heather,
Thank you again for calling in. Attached is the fill design for construction that was discussed
this morning. Please let me know if you have any questions.

Dear Tim and Kile,
We used our most recent BD data and revised the fill templates. Please see the
attached PDF drawings. The attached Excel file contains a list of control points
for these templates. Between the drawings and the Excel file, you should be able
to incorporate CSE's templates (at 500 -ft spacing) to your field templates (at 100 -
ft spacing) using your own BD data collected by the third party licensed PLS.

The key factor is that the dune should be tied in with the existing +12 ft NAVD
contour (wherever possible), and the berm with the existing +6 ft NAVD contour.
The dune width, berm width, seaward edge of the berm, and the fill slope in the
attached files are designed to guide you to achieve the project volume. You may
make minor modifications to them based on the site conditions at the time of
construction and the actual fill quantities along the finished sections. You shall
submit your final templates (cross-section plots in PDF and volume sheets in
Excel) for Engineer's approval before nourishment commences along a
section of beach.
The total contract quantity after the revisions should remain unchanged, ie - 4
million cubic yards. Fill quantities for each reach should be within plus or minus
10 percent of the design quantities shown in the bid documents under the
"Maximum Fill" scenario. For your convenience, below are the volumes
designed for each reach.
Reach 1 (stations 497+00 to 790+00): 1,758,000 cy
Reach 2 (stations 790+00 to 920+00): 845,000 cy
Reach 3N (stations 920+00 to 975+00): 622,000 cy
Reach 3S (stations 975+00 to 1010+00): 543,000 cy
Reach 4 (stations 1010+00 to 1025+00): 232,000 cy
After you have a chance to work on the templates, I suggest we have a site visit
with the Town particularly along Reaches 3 and 4 and the northern sections of
beach that will receive nourishment sand first. I will follow up with David for
that schedule and let you know the date and the time.
Also, per your earlier request, Drew will send you CSE's BD data in an xyz
format in a separate email by tomorrow.
As always, feel free to contact me if you have any questions.
Best regards,
Haiqing
