Waukesha County - Hydrologic Soil Group

Description:

This dataset was automatically cataloged from the creator's Open Data Portal. In some cases, publication year and bounding coordinates shown here may be incorrect. Additional download formats may be available on the author's website. Please check the Resource Link for additional information.

This data set is a
digital soil survey and generally is the most detailed level of soil geographic
data developed by the National Cooperative Soil Survey. The information was
prepared by digitizing maps, by compiling information onto a planimetric
correct base and digitizing, or by revising digitized maps using remotely
sensed and other information.

This data set consists of georeferenced digital map data and
computerized attribute data. The map data are in a soil survey area extent
format and include a detailed, field verified inventory of soils and
miscellaneous areas that normally occur in a repeatable pattern on the
landscape and that can be cartographically shown at the scale mapped. A special
soil features layer (point and line features) is optional. This layer displays
the location of features too small to delineate at the mapping scale, but they
are large enough and contrasting enough to significantly influence use and
management. The soil map units are linked to attributes in the National Soil
Information System relational database, which gives the proportionate extent of
the component soils and their properties.

Building Limitations

1. Description


A definition query was performed
on each of the limitations using the soils database. In order to avoid
duplication of features from three soil types (Pm, RkE & RlA), the erase
function was used from ArcToolbox. By erasing the Depth to Bedrock from the
the <1 Foot to Water Table, the result of that process erased from the
<3 Feet to Water Table and finally that result erased from the Percent
Slope, a heirarchy was established. In order of priority: <1 Foot to Water
Table, <3 Feet to Water Table, Shallow Bedrock and Slopes >12%.

Depth to Seasonal High Water Table

1. Description


Soil polygons displayed, by color,
according to the DEPTH_TO_WATER_TABLE value field of the soils database.
Depths were combined to create a specific range.

Hydric Classification

1. Description


Soil polygons displayed according
to the HYDRIC_CODE value field of the soils database. Hydric and Hydric
Inclusions were then color coded.

Hydrologic Soil Group (Native Condition)

1. Description


Soil polygons displayed according
to the HYDRIC_SOIL_GROUP value field of the soils database. The different
soil groups were then color coded. Dual Hydrologic Groups (A/D, B/D &
C/D) represent drained and undrained conditions. D was designated for these
groups to represent the native condition of the soil.

Hydrologic Soil Group (Native Condition)

1. Description


Soil polygons displayed according
to the HYDRIC_SOIL_GROUP value field of the soils database. The different
soil groups were then color coded. Dual Hydrologic Groups (A/D, B/D &
C/D) represent drained and undrained conditions. D was designated for these
groups to represent the native condition of the soil.

Percent Slope

1. Description


Soil polygons displayed, by color,
according to the SLOPE_PERCENT value field of the soils database. Slope
percentages were combined to create a range.

Stormwater Infiltration Potential

1. Description


Stormwater Infiltration Potential
within Waukesha County.

Land Capability Class

1. Description


Soil polygons displayed according
to the LAND_CAPABILITY_CLASS value field of the soils database. Capability
classes were then grouped and color coded.

Soils Parent Material

1. Description


This layer shows generalized soil
composition groups based on parent material

Surface Textures

1. Description


Soil polygons displayed, by color,
according to the SURFACE_TEXTURE value field of the soils database. Sandy
Soils = Course Sand, Fine Sand, Fine Sandy Loam, Gravelly Sand and Loamy
Sand. Loamy Soils = Loam and Sandy Loam. Silty Loam Soils = Silt Loam. Clayey
Soils = Clay, Silty Clay and Silty Clay Loam. Muck Soils = Muck.
