5.3.1 TOPOGRAPHY Based on visual observations, the topography of the subject property is relatively flat. The United States Geological Survey (USGS) 7.5' Topographic Map, La Porte, Texas Quadrangle indicate that the property is located at an elevation of approximately 21 feet above sea level. The regional groundwater gradient is southeast toward the Gulf of Mexico. A copy of the topographic map on be seen in Figures 5.3.2 GEOLOGY According to the Geologic Atlas of Texas published by the Bureau of Economic Geology at the Balcones Research Center in Austin, the subject property is located in the Beaumont Formation(s) and is identified as symbol(s) Qb-stipled on the Atlas Map, The Beaumont Formation is mostly clay, silt, and sand; includes mainly stream channel, point -bar, natural levee, backswamp, and to a lesser extent coastal marsh and mud flat deposits; concretions of calcium carbonate, iron oxide, and iron -manganese oxides in zone of weathering; surface almost featureless, characterized by relict river channels shown by meander patterns and pimple mounds on meanderbett ridges, separated by areas of low, relatively smooth, featureless backswamp deposits without pimple mounds; thickness 3100 feet. The stippled overprint (source shown in Index to Geologic Mapping) shows areas that are "Dominantly clay and mud of low permeability, high water -holding capacity, high compressibility, high to very high shrink -swell potential, poor drainage, level to depressed relief, low shear strength, and high plasticity; geologic units include interdistributary muds, abandoned channel fill muds, and overbank fluvial muds. The nonstippled areas are "Dominantly clayey sand and silt of moderate permeability, and drainage, low to moderate compressibility and shrink -swell potential, level relief with local mounds and ridges, and high shear strength; geologic units include meanderbelt, levee, crevasse splay, and distributary sands According to the United States Department of Agriculture (USDA) and Natural Resources Conservation Service INKS), Soil Survey the soil type underlying the subject property is classified as the bernard series The Bernard series consists of very deep, somewhat poorly drained, very slowly permeable soils that formed in thick clayey sediments on marine terraces of Pleistocene age. These soils are on broad Coastal Prairies. Slopes range from 0 to 1 percent. TAXONOMIC CLASS: Fine, smectitic, thermic Vertic Argiaquolls TYPICAL PEDON: Bernard clay loam —cropland.
