Fill design is based on the beach condition in August 2020. The actual
limit of fill will be the +7 ft NAVD contour at the time of construction.
The final configuration and limits of beach construction will be determined
based on conditions at the time of construction and the aggregate total fill
e + volume that can be accomplished within the available budget for the
a . '`' s project. The indicated quantities are maximum amounts to be permitted.
�c The project will not fill or cover any emergency shore protection
k` structures such as sandbags. Buffers (no work areas) alongshore will be
12` < Ja maintained around areas of active bird nesting at the time of construction
t r^ n consultation with NPS biologists. To extent practicable, the construction
berm will shift seaward of Mean Low Water at sites of nests then reenter
the existing beach outside of the buffer zone.
