The map unit descriptions in this report, along with the maps, can be used to determine the composition and properties of a unit. A map unit delineation on a soil map represents an area dominated by one or more major kinds of soil or miscellaneous areas. A map unit is identified and named according to the taxonomic classification of the dominant soils. Within a taxonomic class there are precisely defined limits for the properties of the soils. On the landscape, however, the soils are natural phenomena, and they have the characteristic variability of all natural phenomena. Thus, the range of some observed properties may extend beyond the limits defined for a taxonomic class. Areas of soils of a single taxonomic class rarely, if ever, can be mapped without including areas of other taxonomic classes. Consequently, every map unit is made up of the soils or miscellaneous areas for which it is named and some minor components that belong to taxonomic classes other than those of the major soils. The Map Unit Description (Brief, Generated) report displays a generated description of the major soils that occur in a map unit. Descriptions of non-soil (miscellaneous areas) and minor map unit components are not included. This description is generated from the underlying soil attribute data. Additional information about the map units described in this report is available in other Soil Data Mart reports, which give properties of the soils and the limitations, capabilities, and potentials for many uses.Also,the narratives that accompany the Soil Data Mart reports define some of the properties included in the map unit descriptions. Report—Map Unit Description (Brief, Generated) Albemarle County, Virginia Map Unit: 2C—Albemarle fine sandy loam, 7 to 15 percent slopes Component: Albemarle (80%) The Albemarle component makes up 80 percent of the map unit. Slopes are 7 to 15 percent. This component is on hillslopes, piedmonts. The parent material consists of residuum weathered from metasedimentary rock. Depth to a root restrictive layer, bedrock, paralithic, is 35 to 60 inches. The natural drainage class is well drained. Water movement in the most restrictive layer is moderately high. Available water to a depth of 60 inches is moderate. Shrink-swell potential is low. This soil is not flooded. It is not ponded. There is no zone of water saturation within a depth of 72 inches. Organic matter content in the surface horizon is about 2 percent. Nonirrigated land capability classification is 3e. This soil does not meet hydric criteria.

Slopes are 15 to 25 percent. This component is on hillslopes, piedmonts. The parent material consists of residuum weathered from granite and gneiss. Depth to a root restrictive layer is greater than 60 inches. The natural drainage class is well drained. Water movement in the most restrictive layer is high. Available water to a depth of 60 inches is moderate. Shrink-swell potential is low. This soil is not flooded. It is not ponded. There is no zone of water saturation within a depth of 72 inches. Organic matter content in the surface horizon is about 1 percent.Nonirrigated land capability classification is 7s. This soil does not meet hydric criteria. Map Unit: 48E—Louisburg very stony sandy loam, 25 to 45 percent slopes Component: Louisburg (75%) The Louisburg component makes up 75 percent of the map unit. Slopes are 25 to 45 percent. This component is on hillslopes, piedmonts. The parent material consists of residuum weathered from granite and gneiss. Depth to a root restrictive layer is greater than 60 inches. The natural drainage class is well drained. Water movement in the most restrictive layer is high. Available water to a depth of 60 inches is moderate. Shrink-swell potential is low.

Organic matter content in the surface horizon is about 1 percent.Nonirrigated land capability classification is 7s. This soil does not meet hydric criteria. Map Unit: 76—Riverview loam Component: Riverview (75%) The Riverview component makes up 75 percent of the map unit. Slopes are 0 to 2 percent. This component is on river valleys, flood plains. The parent material consists of alluvium derived from igneous rock. Depth to a root restrictive layer is greater than 60 inches.The natural drainage class is well drained.Water movement in the most restrictive layer is moderately high. Available water to a depth of 60 inches is moderate. Shrink-swell potential is low. This soil is occasionally flooded. It is not ponded.A seasonal zone of water saturation is at 48 inches during January, February, March, December.Organic matter content in the surface horizon is about 1 percent. Nonirrigated land capability classification is 2w. This soil does not meet hydric criteria.

The information, however, has limitations. For example, estimates and other data generally apply only to that part of the soil between the surface and a depth of 5 to 7 feet. Because of the map scale, small areas of different soils may be included within the mapped areas of a specific soil. The information is not site specific and does not eliminate the need for onsite investigation of the soils or for testing and analysis by personnel experienced in the design and construction of engineering works. Government ordinances and regulations that restrict certain land uses or impose specific design criteria were not considered in preparing the information in this table. Local ordinances and regulations should be considered in planning, in site selection, and in design.
