Warning: Soil Map may not be valid at this scale.
Enlargement of maps beyond the scale of mapping can cause
misunderstanding of the detail of mapping and accuracy of soil
line placement. The maps do not shover the small areas of
contrasting soils that could have been shown at a more detailed
scale.
Please rely on the bar scale on each map sheet for rnap
measurements.

Maps from the lVeb 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_

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.

Unpaved Local Roads and Streets Weld County, Colorado, Southerrt Part
Description
Unpaved local roads and streets are those roads and streets that carry traffic
year round but have a graded surface of local soil material or aggregate.
Description:
Unpaved local roads and streets are those roads and streets that carry traffic
year round but have a graded surface of local soil material or aggregate.
The roads and streets consist of
(1) the underlying local soil material, either cut or fill, which is called "the sub -
grade";
a
(2) the surface, which may be the same as the su bgrad a or may have agg rate
such as crushed limestone added,
They are graded to shed water, and conventional drainage measures are
provided. These roads and streets are built mainly from the sail at the site. Soil
interpretations for local roads and streets are used as a tool in evaluating sail
suitability and identifying soil limitations for the practice. The rating is for sails in
their present condition and does not consider present land use. Soil properties
and qualities that affect local roads and streets are those that influence the ease
of excavation and grading and the traffic -supporting capacity. The properties and
qualities that affect the ease of excavation and grading are hardness of bedrock
or a cemented pan, depth to bedrock or a cemented pan, depth to a water table,
flooding, the amount of I a rg a stones, and slope. The properties that affect traffic -
supporting capacity are soil strength as inferred from the AASHTO group index
and the Unified classification, subsidence, shrink -swell behavior, potential frost
action, and depth to the seasonal high water table, The dust generating tendaoy
of the soil is also considered.
