has migrated inland about 20 m. However, through reconstruction, the built
foredune has shifted seaward about 11 m. The constructed foredune is intermittently scarped and eroded, to be further tended to with emplaced sediment, a
variety of fence lines, and planted vegetation.
3.5.5 Manipulation: Constructed Foredune, Landward
(Human Intervention)
There are no examples of a foredune constructed landward of its optimal position
on Fire Island. All foredune construction on Fire Island served to maximize the
space available for housing and infrastructure. However, in other locations there
are instances of ‘‘foredune’’ construction considerably inland of the natural
Fig. 3.10 Natural foredune crestline extending under or near the seaward margin of houses at
Kismet. The constructed foredune is wiped out at intervals. The newly constructed foredune line
has been sited farther seaward at the second house
