Lo_Leon_UrbanLo-Leon-Urban land complex.
This mapping unit is on rims of depressions, on smooth flats, and in indefinite patterns on the uplands
and stream terraces. It consists of areas of Leon soils and Urban land that are too small and too
intermingled to be mapped separately. About 35 to 45 percent of the mapping unit is Leon soils, and
about 30 to 50 percent is Urban land. The percentage of Urban land is greater near towns.
Typically, the surface layer of a Leon soil is very dark gray sand 3 inches thick. The subsurface layer is light
gray sand 13 inches thick. The subsoil is dark reddish brown sand 24 inches thick. The underlying layer, to
a depth of 64 inches, is light gray sand.
Urban land consists of areas where the original soil has been cut, filled, graded, or paved so that most soil
properties have been altered to the extent that a soil series is not recognized. These areas are used for
shopping centers, factories, municipal buildings, apartment complexes, or parking lots, or for other
purposes where buildings are closely spaced or soil is covered with pavement. Slope is generally modified
to fit the site needs. The extent of site modification varies greatly. Many areas are relatively undisturbed,
while other areas have been cut or filled.
Included in mapping are small areas of Seagate, Onslow, Rimini, Murville, Lynn Haven, Kureb, Lakeland,
and Baymeade soils.
The runoff of the Urban Land part of this mapping unit is greater than that of the Leon soils because of
the impervious cover of buildings, streets, and parking lots.
A seasonal high water table and leaching of plant nutrients are the main limitations in the use and
management of this complex. Most lawn grasses, shrubs, and trees are easily established and maintained.
Some soil conditioners and liberal amounts of fertilizer may be needed in most areas. Capability subclass
not assigned; Leon part in woodland group 4w, Urban land part not placed in a woodland group.
