The map units delineated on the detailed soil maps in a soil survey represent the soils or miscellaneous areas
map unit descriptions in this report,along with the maps,can be used to determine the composition and pro'
unit delineation on a soil map represents an area dominated by one or more major kinds of soil or miscellane

defined limits for the properties of the soils On the landscape,however,the soils are natural phenomena,an
characteristic variability of all natural phenomena.Thus,the range of some observed properties may extend
for a taxonomic dass Areas of soils of a single taxonomic class rarely,if ever,can be mapped without indud
taxonomic classes Consequently,every map unit is made up of the soils or miscellaneous areas for which it
components that belong to taxonomic classes other than those of the major soils.
The"Map Unit Description(Brief)"report gives a brief,general description of the major soils that occur in a n

Roads and Streets,Shallow Excavations,Lawns and Landscaping
Soil properties influence the development of building sites,including the selection of the site,the design of tf
performance after construction,and maintenance.This table shows the degree and kind of soil limitations tht
streets,shallow excavations,and lawns and landscaping.
The ratings In the table are both verbal and numerical Rating class terms indicate the extent to which the so
soil features that affect building site development.Not limited indicates that the soil has features that are vel
specified use Good performance and very low maintenance can be expected Somewhat limited indicates thz
that are moderately favorable for the specified use.The limitations can be overcome or minimized by special
installation.Fair performance and moderate maintenance can be expected.Very limited indicates that the so'
features that are unfavorable for the specified use The limitations generally cannot be overcome without ma
special design,or expensive installation procedures.Poor performance and high maintenance can be expecte
Numerical ratings in the table indicate the severity of individual limitations.The ratings are shown as decimal
0.01 to 1.00 They indicate gradations between the point at which a soil feature has the greatest negative im
and the point at which the soil feature is not a limitation(0.00).
Local roads and streets have an all-weather surface and carry automobile and light truck traffic all year.The)

Risk of corrosion pertains to potential soil-induced electrochemical or chemical action that corrodes or weake

the steel or concrete in installations that are entirely within one kind of soil or within one soil layer.
For uncoated steel,the risk of corrosion,expressed as low,moderate,or high,is based on soil drainage class
resistivity near field capacity,and electrical conductivity of the saturation extract.
For concrete,the risk of corrosion also is expressed as low,moderate,or high.It is based on soil texture,ad
in the saturation extract.
