This mapping unit is on broad, smooth flats on uplands. It consists of areas of Seagate 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 Seagate 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 Seagate soil is dark gray fine sand 8 inches thick. The subsurface layer is
light gray fine sand 4 inches thick. Below this, to a depth of 36 inches, is fine sand that is dark brown in
the upper part, brown in the middle part, and light gray in the lower part. The subsoil, to a depth of 66
inches, is mottled brownish yellow sandy loam in the upper part and light gray clay loam in the lower part.
Urban land consists of areas where the original soils have 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 now
used for shopping centers, factories, municipal buildings, apartment complexes, or parking lots, or for
other purposes where buildings are closely spaced or soil is eovered with pavement. Slope is generally
modified to fit the site needs. The extent of site modification varies greatly. Many areas are relatively
undisturbed, other areas have been cut down, and still other areas have been filled.
Included in mapping are small areas of Leon, Onslow, Rimini, Torhunta, Murville, Lynn Haven, Kureb,
Baymeade, and Lakeland soils.
Runoff is greater on Urban land than on the Seagate soils because of the impervious cover of buildings,
streets, and parking lots.
A seasonal high water table is the main limitation in the use and management of this complex.
Supplemental irrigation and soil conditioners may be needed to establish lawns, shrubs, and trees.
Capability subclass not assigned; Seagate part in woodland group 3w, Urban land part not placed in a
woodland group.
