Fortress soils are on nearly level to strongly sloping modified landforms. These soils formed in anthropotransported soil material from eolian sand, outwash or dredging activities along coastal waterways, lakes and rivers, in and near major urbanized areas of the Northeast. Slope ranges from 0 to 8 percent. Mean annual precipitation ranges from 40 to 50 inches. Barren and Jamaica soils occur in lower landscape positions and have water tables at shallower depths.
Bigapple soils occur in higher landscape positions.
Verazano soils have a contrasting particle size class within the control section. Moderately well drained. The potential for surface runoff is very low. Permeability is rapid. Most of these soils are used for recreation, beach cottages, and wildlife.
