Prepared for Taproot Rockies Midstream, LLC
Planning Questions:
1. Explain, in detail, the proposed use of the property.
Taproot Rockies Midstream, LLC is requesting a use by Special Review permit for a
commercial office and garage to be used by a midstream services company. Company
pickup trucks will be parked on -site for employee use during business hours. Some outdoor
and indoor storage of pipes, pipeline construction materials and other equipment may occur
but is not the primary use of the site. This application is intended to be process in conjunction
with a 2 -Lot recorded exemption, F E I8-001 , as the site will be located on Lot A of this
recorded exemption.
2. Explain how this proposal is consistent with the intent of the Weld County Code,
Chapter 22 of the Comprehensive Plan.
Sec. 22-2-20. - Agriculture goals and policies.
G. A. Goal 7. County land use regulations should protect the individual property owner's
rights to request a land use change.
2.A. Policy 72. Conversion of agricultural land to nonurban residential,
commercial, and industrial uses should be accommodated when the subject site is
in an area that can support such development and should be compatible with the
region.
The property owner is requesting to use the existing building for commercial purposes and,
according to Chapter 22 of the Comprehensive Plan, has the right to request this land use
change.
The proposed use is for an office and garage to be used by a midstream services company.
As an oil and gas support and service company, the proposed use is allowed as a use by
Special Review in the A (Agricultural) Zone District. Employees based out of this site will
inspect and maintain natural gas, crude oil, and water conveyance and delivery
infrastructure,
. Explain how this proposal is consistent with the intent of the Weld County Code,
Chapter 23 (Zoning) and the zone district in which it is located.
Sec. 23-3-10. -- Intent Agriculture in the County is considered a valuable resource which
must be protected from adverse impacts resulting from uncontrolled and undirected
business, industrial, and residential land uses. The A (Agricultura/)Zone District is established
to maintain and promote agriculture as an essential feature of the County. The A (Agricultural)
Zone District is also intended to provide areas for the conduct of agricultural activities and
activities related to agriculture and agricultural production without the interference of other,
incompatible land uses. The A (Agricultural) Zone District is also intended to provide areas
for the conduct of Uses by Special Review which have been determined to be more intense
or to have a potentially greater impact than Uses Allowed by 'ight The A (Agricultural) Zone

District regulations are established to promote the health; safety and general welfare of the
present and future residents of the County.
The proposed USR site is located in the Agricultural (A) zone district. As an oil and gas
service company, Taproot Rockies Midstream's proposed use of the site is allowed as a Use
by Special Review in the A zone. The A zone district allows as a Use by Special Review "any
use permitted as a Use by Right, an accessory use, or a Use by Special Review in the
Commercial or Industrial zone districts, provided that the property is not a Lot in an approved
or recorded subdivision plat or lots part of a map or plan filed prior to the adoption of any
regulations controlling subdivisions." offices are allowed as a Use by Right in Commercial
zone districts and parking areas for commercial vehicles are allowed as an accessory use in
Commercial zone districts. The proposed use is therefore allowed as a Use by Special
Review in the A zone. While it is not an agricultural activity, the proposed use will allow
Taproot Rockies Midstream to inspect and maintain pipelines located on agricultural lands,
serving to protect agricultural land from adverse impacts resulting from uncontrolled and
undirected business and industrial uses. The proposed use is therefore consistent with
Section 23-3-10 of the Weld County Code.

Summary
The project site for the proposed USR is an agricultural property with an existing
structure. The applicant is proposing outdoor storage as well as parking in the existing
gravel drive area and to repurpose the existing building into an office and a garage. The
overall percent imperviousness of the site should not be altered. The proposed
development plan for the site does not significantly change the conditions of the site and,
therefore, is exempt from stormwater detention per Article XII, Storm Drainage
Criteria, Section 23-12-30 Drainage Policy.
F. Exceptions.
Exceptions to stormwater detention shall not jeopardize the public
health, safety, , and welfare ofpublic and private property and shall be
limited to the following:
a. No stormwater detention will be requiredfor sites that meet any of
the following conditions. Requirements of the Municipal Separate
Storm Sewer System (MS4) areas remain applicable.

Introduction
1. Location
The proposed site is located in proposed Lot A of R EC 1 S -0115 being part of Section
11, T8N, R61 , 6th PM. This site is located north of Highway 14 and northeast of the
Town of Briggsdale, CO. The properties surrounding the site are undeveloped,
agricultural farm land. The property is bordered on the east side by Weld County Road
(WCR) 95, The nearest road to the south, is Highway 14, to the west is WCR 89 and to
the north is WCR 96. A vicinity map is shown in Appendix A.
. Property Description
The applicant is proposing the development of proposed Lot A which is approximately
13.52 acres of the 161.05 -acre property. The site is currently a non -urbanizing,
agricultural property with an existing structure. The applicant is proposing outdoor
storage as well as parking in the existing gravel drive area and to repurpose the existing
building into an office and a garage. No hazardous materials will be stored on site.
There are two types of soil: Platner loam (0% to 3% slopes) and Playas. The majority of
the soil is well drained, hydrologic soil group C (see USDA - RCS soil report in.
Appendix B).
There are no major open channels within or adjacent to the proposed property.

Historic Drainage
1. Overall Basin Description
The site has a relatively flat topography with slopes from zero to three percent
predominately towards a depression on the western side of the property. A topographic
map was downloaded from the United States Geological Survey (USGS) website and is
shown in Appendix C. The overall percentage of imperviousness for the existing site is
estimated to be approximately four percent using the Urban Drainage and Flood Control
District (UDFCD) and the Weld County Engineering and Construction Guidelines
(WCECG) manual recommended values (see calculation in Appendix D). Since the
proposed site changes do not add impervious surface area, the percentage of
imperviousness should not be altered. Historically, there have been no previous drainage
issues with the property.
A Federal Emergency Management Administration (FEMA) map of the project area is
included in Appendix E. The property is located on. panel 081 1050E, but it has not
been printed yet. The proposed site is located in FEMA Zone D which indicates a
possibility of flood hazards, but no analysis has been conducted. Since there are no major
bodies of water or rivers located within or adjacent to the property, the proposed site is
not considered a high -risk area for floods.
. Drainage Patterns Through Property
The site is located in rural Weld County and is surrounded by undeveloped, agricultural
land. A Master Plan for the site area is not currently available. The site is mostly west
sloping and has a generally flat topography. Historically, the basin drainage flows
towards a depression west of the site.
3. Ofd -site Drainage Flow Patterns
offsite flows from the north and the south should continue to flow west, around the site
and ultimately towards the depression that is located west of the site. Offsite flows from
the west flow east towards this depression. Offsite flows from the east are intercepted by
WCR 95. Therefore, an increase in runoff is not expected.

Conclusions
This drainage narrative is consistent with the Weld County Engineering and Construction
Guidelines and the UDFCD Criteria Manual. An increased risk of damage from storm
runoff is not expected since the development plan for the site should not significantly
change the existing conditions. We recommend that the site is exempt from stormwater
detention per Article XII, Storm Drainage Criteria, Section 23-12-30 Drainage
Policy.

Preface
Soil surveys contain information that affects land use planning in survey areas.
They highlight soil limitations that affect various land uses and provide information
about the properties of the soils in the survey areas. Soil surveys are designed for
many different users, including farmers, ranchers, foresters, agronomists, urban
planners, community officials, engineers,developers, builders, and home buyers.
Also, conservationists, teachers, students, and specialists in recreation, waste
disposal, and pollution control can use the surveys to help them understand,
protect, or enhance the environment.
Various land use regulations of Federal, State, and local governments may impose
special restrictions on land use or land treatment. Soil surveys identify soil
properties that are used in making various land use or land treatment decisions.
The information is intended to help the land users identify and reduce the effects of
soil limitations on various land uses. The landowner or user is responsible for
identifying and complying with existing laws and regulations.
Although soil survey information can be used for general farm, local, and wider area
planning, onsite investigation is needed to supplement this information in some
cases. Examples include soil quality assessments (http:// ww.nres.usda.govlwps/
portalfnres/main/soils/health/) and certain conservation and engineering
applications. For more detailed information, contact your local USDA Service Center
(https://offices.sc.egov.usda.gov/locator/apps'agency=Arcs) or your NRCS State Soil
Scientist (It p://www.nrcs.usda,goviwpsiportalinrcsidetailisoilsicontactust?
cid=nres14 p2_05 95I ).
Great differences in soil properties can occur within short distances. Some soils are
seasonally wet or subject to flooding. Some are too unstable to be used as a
foundation for buildings or roads. Clayey or wet soils are poorly suited to use as
septic tank absorption fields. A high water table makes a soil poorly suited to
basements or underground installations.
The National Cooperative Soil Survey is a joint effort of the United States
Department of Agriculture and other Federal agencies, State agencies including the
Agricultural Experiment Stations, and local agencies. The Natural Resources
Conservation Service (NR S) has leadership for the Federal part of the National
Cooperative Soil Survey.
Information about soils is updated periodically. Updated information is available
through the NRCS Web Soil Survey, the site for official soil survey information.

How Soil Surveys Are Made
Soil surveys are made to provide information about the soils and miscellaneous
areas in a specific area. They include a description of the soils and miscellaneous
areas and their location on the landscape and tables that show soil properties and
limitations affecting various uses. Soil scientists observed the steepness, length,
and shape of the slopes; the general pattern of drainage; the kinds of crops and
native plants; and the kinds of bedrock, They observed and described many soil
profiles. A soil profile is the sequence of natural layers, or horizons, in a soil. The
profile extends from the surface down into the unconsolidated material in which the
soil formed or from the surface down to bedrock. The unconsolidated material is
devoid of roots and other living organisms and has not been changed by other
biological activity.
Currently, soils are mapped according to the boundaries of major land resource
areas (IMILRAs). PALRAs are geographically associated land resource units that
share common characteristics related to physiography, geology, climate, water
resources, soils, biological resources, and land uses (USDA, 2006). Soil survey
areas typically consist of parts of one or more MLRA.
The soils and miscellaneous areas in a survey area occur in an orderly pattern that
is related to the geology, landforms, relief, climate, and natural vegetation of the
area. Each kind of soil and miscellaneous area is associated with a particular kind
of landform or with a segment of the landform. By observing the soils and
miscellaneous areas in the survey area and relating their position to specific
segments of the landform, a soil scientist develops a concept, or model, of how they
were formed. Thus, during mapping, this model enables the soil scientist to predict
with a considerable degree of accuracy the kind of soil or miscellaneous area at a
specific location on the landscape.
Commonly, individual soils on the landscape merge into one another as their
characteristics gradually change. To construct an accurate soil map, however, soil
scientists must determine the boundaries between the soils. They can observe only
a limited number of soil profiles. Nevertheless, these observations, supplemented
by an understanding of the soil -vegetation -landscape relationship, are sufficient to
verify predictions of the kinds of soil in an area and to determine the boundaries.
Soil scientists recorded the characteristics of the soil profiles that they studied. They
noted soil color, texture, size and shape of soil aggregates, kind and amount of rock
fragments, distribution of plant roots, reaction, and other features that enable them
to identify soils. After describing the soils in the survey area and determining their
properties, the soil scientists assigned the soils to taxonomic classes (units) .
Taxonomic classes are concepts, Each taxonomic class has a set of soil
characteristics with precisely defined limits. The classes are used as a basis for
comparison to classify soils systematically. Soil taxonomy, the system of taxonomic
classification used in the United States, is based mainly on the kind and character
of soil properties and the arrangement of horizons within the profile. After the soil
5
Custom Soil Resource Report
scientists classified and named the soils in the survey area, they compared the
individual soils with similar soils in the same taxonomic class in other areas so that
they could confirm data and assemble additional data based on experience and
research.
The objective of soil mapping is not to delineate pure map unit components; the
objective is to separate the landscape into landforms or landform segments that
have similar use and management requirements. Each map unit is defined by a
unique combination of soil components and/or miscellaneous areas in predictable
proportions. Some components may be highly contrasting to the other components
of the map unit. The presence of minor components in a map unit in no way
diminishes the usefulness or accuracy of the data. The delineation of such
landforms and landform segments on the map provides sufficient information for the
development of resource plans. If intensive use of small areas is planned, onsite
investigation is needed to define and locate the soils and miscellaneous areas.
Soil scientists make many field observations in the process of producing a soil map.
The frequency of observation is dependent upon several factors, including scale of
mapping, intensity of mapping, design of map units, complexity of the landscape,
and experience of the soil scientist. Observations are made to test and refine the
soil -landscape model and predictions and to verify the classification of the soils at
specific locations. Once the soil -landscape model is refined, a significantly smaller
number of measurements of individual soil properties are made and recorded.
These measurements may include field measurements, such as those for color,
depth to bedrock, and texture, and laboratory measurements, such as those for
content of sand, silt, clay, salt, and other components. Properties of each soil
typically vary from one point to another across the landscape.
Observations for map unit components are aggregated to develop ranges of
characteristics for the components. The aggregated values are presented. Direct
measurements do not exist for every property presented for every map unit
component. Values for some properties are estimated from combinations of other
properties.
While a soil survey is in progress, samples of some of the soils in the area generally
are collected for laboratory analyses and for engineering tests. Soil scientists
interpret the data from these analyses and tests as well as the field -observed
characteristics and the soil properties to determine the expected behavior of the
soils under different uses. Interpretations for all of the soils are field tested through
observation of the soils in different uses and under different levels of management.
Some interpretations are modified to fit local conditions, and some new
interpretations are developed to meet local needs. Data are assembled from other
sources, such as research information, production records, and field experience of
specialists. For example, data on crop yields under defined levels of management
are assembled from farm records and from field or plot experiments on the same
kinds of soil/
Predictions about soil behavior are based not only on soil properties but also on
such variables as climate and biological activity. Soil conditions are predictable over
long periods of time, but they are not predictable from year to year. For example,
soil scientists can predict with a fairly high degree of accuracy that a given soil will
have a high water table within certain depths in most years, but they cannot predict
that a high water table will always be at a specific level in the soil on a specific date.
After soil scientists located and identified ied the significant natural bodies of soil in the
survey area, they drew the boundaries of these bodies on aerial photographs and
6

identified each as a specific map unit. Aerial photographs show trees, buildings,
fields, roads, and rivers, all of which help in locating boundaries accurately.
Soil Map
The soil map section includes the soil map for the defined area of interest, a list of
soil map units on the map and extent of each map unit, and cartographic symbols
displayed on the map. Also presented are various metadata about data used to
produce the map, and a description of each soil map unit.

Map Unit Descriptions

The map units delineated on the detailed soil reaps in a soil survey represent the
soils or miscellaneous areas in the survey area. The map unit descriptions, 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.
Most minor soils have properties similar to those of the dominant soil or soils in the
map unit, and thus they do not affect use and management. These are called
noncontrasting, or similar, components. They may or may not be mentioned in a
particular map unit description. Other minor components, however, have properties
and behavioral characteristics divergent enough to affect use or to require different
management. These are called contrasting, or dissimilar, components. They
generally are in small areas and could not be mapped separately because of the
scale used. Some small areas of strongly contrasting soils or miscellaneous areas
are identified by a special symbol on the maps. If included in the database for a
given area, the contrasting minor components are identified in the map unit
descriptions along with some characteristics of each. A few areas of minor
components may not have been observed, and consequently they are not
mentioned in the descriptions, especially where the pattern was so complex that it
was impractical to make enough observations to identify all the soils and
miscellaneous areas on the landscape.
The presence of minor components in a map unit in no way diminishes the
usefulness or accuracy of the data. The objective of mapping is not to delineate
pure taxonomic classes but rather to separate the landscape into landfcrms or
landform segments that have similar use and management requirements. The
delineation of such segments on the map provides sufficient information for the
development of resource plans. If intensive use of small areas is planned, however,
11

Custom Soil Resource Report
onsite investigation is needed to define and locate the soils and miscellaneous
areas.
An identifying symbol precedes the map unit name in the map unit descriptions.
Each description includes general facts about the unit and gives important soil
properties and qualities.
Soils that have profiles that are almost alike make up a soil series. Except for
differences in texture of the surface layer, all the soils of a series have major
horizons that are similar in composition, thickness, and arrangement,
Soils of one series can differ in texture of the surface layer, slope, stoniness,
salinity, degree of erosion, and other characteristics that affect their use. On the
basis of such differences, a soil series is divided into soil phases. Most of the areas
shown on the detailed soil maps are phases of soil series. The name of a soil phase
commonly indicates a feature that affects use or management. For example, Alpha
silt loam, o to 2 percent slopes, is a phase of the Alpha series.
Some map units are made up of two or more major soils or miscellaneous areas.
These map units are complexes, associations, or undifferentiated groups.
A complex consists of two or more soils or miscellaneous areas in such an intricate
pattern or in such small areas that they cannot be shown separately on the maps.
The pattern and proportion of the soils or miscellaneous areas are somewhat similar
in all areas. Alpha -Beta complex, 0 to 6 percent slopes, is an example,
An association is made up of two or more geographically associated soils or
miscellaneous areas that are shown as one unit on the maps. Because of present
or anticipated uses of the map units in the survey area, it was not considered
practical or necessary to map the soils or miscellaneous areas separately. The
pattern and relative proportion of the soils or miscellaneous areas are somewhat
similar. Alpha -Beta association, 0 to 2 percent slopes, is an example.
An undifferentiated group is made up of two or more soils or miscellaneous areas
that could be mapped individually but are mapped as one unit because similar
interpretations can be made for use and management. The pattern and proportion
of the soils or miscellaneous areas in a mapped area are not uniform. An area can
be made up of only one of the major soils or miscellaneous areas, or it can be made
up of all of them. Alpha and Beta soils, 0 to 2 percent slopes, is an example.
Some surveys include miscellaneous areas. Such areas have little or no soil
material and support little or no vegetation. Rock outcrop is an example.
