Landward Fill Limit r -Dune Crest @ +13 ft NAVD
Note
Fill design is based on the beach condition in June 2022.
The actual limit of fill will be the +7 ft NAVD contour at the
time of construction.
Buffers (no work areas) alongshore will be maintained
around areas of active bird nesting at the time of y `
construction in consultation with NPS biologists. To the
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.
