Different drainage classes within one study area
In its 1986 industrial park study, the Pinelands Commission listed Downer loamy sand, Aura sandy loam and Lakewood sand among the better-drained mapped soils. The same study found Hammonton and Klej soils with shallower seasonal groundwater. We keep the study's limits clear: it covers a defined tract, not every residential block.
Its practical lesson is that the word 'sand' isn't enough for a drainage recommendation. We check what happens beside your footing and inside the lower level. A dry-looking surface cannot, by itself, settle the question of water beneath the floor.
