Coordinate System: Web Mercator (EPSG:3857)
Maps from the Web Soil Survey are based on the Web Mercator
projection, which preserves direction and shape but distorts
distance and area. A projection that preserves area, such as the
Albers equal-area conic projection, should be used if more
accurate calculations of distance or area are required.

Soil map units are labeled (as space allows) for map scales

The orthophoto or other base map on which the soil lines were
compiled and digitized probably differs from the background
imagery displayed on these maps. As a result, some minor
shifting of map unit boundaries may be evident.

Description
Farmland classification identifies map units as prime farmland, farmland of
statewide importance, farmland of local importance, or unique farmland. It
identifies the location and extent of the soils that are best suited to food, feed,
fiber, forage, and oilseed crops. NRCS policy and procedures on prime and
unique farmlands are published in the "Federal Register," Vol. 43, No. 21,
January 31, 1978.

Description
This rating indicates the percentage of map units that meets the criteria for hydric
soils. Map units are composed of one or more map unit components or soil
types, each of which is rated as hydric soil or not hydric. Map units that are made
up dominantly of hydric soils may have small areas of minor nonhydric
components in the higher positions on the landform, and map units that are made
up dominantly of nonhydric soils may have small areas of minor hydric
components in the lower positions on the landform. Each map unit is rated based
on its respective components and the percentage of each component within the
map unit.
The thematic map is color coded based on the composition of hydric
components. The five color classes are separated as 100 percent hydric
components, 66 to 99 percent hydric components, 33 to 65 percent hydric
components, 1 to 32 percent hydric components, and less than one percent
hydric components.
In Web Soil Survey, the Summary by Map Unit table that is displayed below the
map pane contains a column named 'Rating'. In this column the percentage of
each map unit that is classified as hydric is displayed.
Hydric soils are defined by the National Technical Committee for Hydric Soils
(NTCHS) as soils that formed under conditions of saturation, flooding, or ponding
long enough during the growing season to develop anaerobic conditions in the
upper part (Federal Register, 1994). Under natural conditions, these soils are
either saturated or inundated long enough during the growing season to support
the growth and reproduction of hydrophytic vegetation.
The NTCHS definition identifies general soil properties that are associated with
wetness. In order to determine whether a specific soil is a hydric soil or nonhydric
soil, however, more specific information, such as information about the depth and
duration of the water table, is needed. Thus, criteria that identify those estimated
soil properties unique to hydric soils have been established (Federal Register,
2002). These criteria are used to identify map unit components that normally are
associated with wetlands. The criteria used are selected estimated soil properties
that are described in "Soil Taxonomy" (Soil Survey Staff, 1999) and "Keys to Soil
Taxonomy" (Soil Survey Staff, 2006) and in the "Soil Survey Manual" (Soil Survey
Division Staff, 1993).
If soils are wet enough for a long enough period of time to be considered hydric,
they should exhibit certain properties that can be easily observed in the field.
These visible properties are indicators of hydric soils. The indicators used to
make onsite determinations of hydric soils are specified in "Field Indicators of
Hydric Soils in the United States" (Hurt and Vasilas, 2006).
