In preparation for this hearing I used the material provided to me by Liz
Fancher for looking at land capability class determination. I completed the
review and analysis using different methods. I have a handout showing the
methods and results. Depending on the method used, the result is different.
The last two pages in the handout summarize my analysis and a conclusion,
and compares my methods and results with the methods and results shown
on pages 6-8 in the Deschutes County CCD newsletter dated 11/26/2012.
Section 11; l18S, R12E
The area in question per correspondence from Liz Fancher on 10/29/2012 is
comprised offour map units, however, two map units (388 and 58C)
account for about 98% (375 acres) of the total area (384 acres).
Map units
38B Oeskamp-Gosney complex, 0 to 8 percent slopes (215 acres)
58C Gosney-Rock outcrop-Oeskamp complex, 0 to 15 percent slopes (160
acres)
The two map units are defined as a complex, which means two or more
major soils occur in a pattern in which the major soils cannot be delineated
separately at the scale of mapping. Each of the major soils has a different
Land Capability Class (LCC) placement
Oeskamp soil is in LCC 6
Gosney soil is in LCC 7
Rock outcrop is in LCC 8
Depending on how the map units and their major components are
evaluated in regards to an overall LCC placement for a area (parcel),
different results may occur .

Based on my correspondence with Douglas Parker on 10/3/2012 and
with Liz Fancher on 11/1/2012, two or even three methods can be
considered for use when attempting to determine the LCC to assign to
any given size area (parcel) of land and the results can be different.
What we have
Map unit 38B=215 acres
Deskamp soil--50% of area (107 acres) and in LCC 6
Gosney soil--35% of area (75 acres) and in LCC 7
Map unit 58C=160 acres
Gosney soil-50% of area (80 acres) and in LCC 7
Rock outcrop-25% of area (40 acres) and in LCC 8
Deskamp soil-20% of area (32 acres) and in LCC6
NOTE; The percent of each soil type that comprises the map unit is in
the soil survey information. The percent area for each map unit does
not add to 100% because of minor soils that are not necessarily
identified in the map unit (called inclusions)

Methods
1. Most limiting soil component;
2. Dominant soil component;
3. Weighted average of major soil
components
____________ Il' """ •• , w ql"#;~~ ________ ~ __ ~ ___ ~_'_".~_.
Method 1; most limiting soil
component
Map unit 38B (215 acres) most limiting component is Gosney
soil (35% of area) or 75 acres in LCC 7.
Map unit 58C (160 acres) most limiting component is Rock
outcrop (25% of area) or 40 acres in LCC 8.
CONCLUSION
100% of the area is considered as > or = LCC 7. This decision is
based on 115 acres of the 375 total acres. Not all soil types in
the map unit are evaluated with this method, only the most
limiting soil type.
Method 2; dominant soil component
Map unit 38B {21S acres} dominant component is
Deskamp soil {SO% of area} or 107 acres in LCC 6.
Map unit S8C {160 acres} dominant component is
Gosney soil {SO% of area} or 80 acres in LCC 7.
CONCLUSION
57% of area is LCC 6 {215 divided by 375} and 43% of
the area is LCC 7 {160 divided by 375}. The decision is
based on 187 acres of the 375 total acres. Not all soil
types in the map unit are evaluated with this method
only the dominant soil type.
This is the method that is used in Web Soil Survey and
is the method used in the correspondence from Liz
Fancher on 10/29/2012.
Method 3; weighted average of
major soil components
Map unit 38B (215 acres)= Deskamp soil (50% of area, 107 acres)
in LCC 6, AND Gosney soil (35% of area, 7S acres) in LCC 7.
Map unit 58C (160 acres)=Gosney soil (50% of area, 80 acres) in
LCC 7, AND Rock outcrop (25% of area, 40 acres) in LCC 8, AND
Deskamp soil (20% of area, 32 acres) in LCC 6.
CONCLUSION
LCC 6 is 37% of the area (107+32 divided by 375), LCC 7 is 41% of
the area (75+80 divided by 375), LCC 8 is 11% of the area (40
divided by 375). The remaining 11% are inclusions or minor soils.
Thus; 52% of the area is > or= LCC 7. The decision is based on 334
acres of the 375 acre total. All soil types in the map unit are
evaluated with this method.
This is the method that was discussed in my correspondence to
Douglas Parker on 10/3/2012 and also addressed in my
correspondence to Liz Fancher on 11/1/2012 concerning the
difference in LCC results based on the use of method 2 and 3.
Summary
Method 1; most limiting soil component, assigns the area (parcel)
to 100%, >or =LCC 7. The determination is based on 115 acres of
the 375 total.
Method 2; dominant soil component, assigns the area (parcel) to
57 % LCC 6 and 43% Lee 7. The determination is based on 187
acres of the 375 total.
Method 3; weighted average of all major soil components, assigns
the area (parcel) to 37% Lee 6, 41% Lee 7 and 11% Lee 8. Thus
52% of the area (parcel) is >or= LCC 7. The determination is based
on 334 acres of the 375 total.
CONCLUSION; method 3 for determining the LCC of an area
(parcel) when the map units are a complex of different soil types,
provides a much better representation of the overallLCC for an
area (parcel) because it evaluates ALL the soil types in a map unit,
not just the most limiting (method 1) or dominant (method 2) soil
type in a map unit.

Deschutes County Commissioners
1300 NW Wall Street, 2nd Floor
Bend, OR 97701
Dear Commissioners:
I am the person who completed the detailed Order 1 Soils Assessment for the Stevens Road Tract "Section 11" for
Oregon Department of State lands that was submitted to Deschutes County on October 27, 2011.
To my understanding the key question before the BOCC is to determine the method to interpret the soils information
regarding soils classification. The purpose of my testimony is to address the issue of soil interpretations for soil
surveys.
It appears you are tasked with trying to understand how to interpret the soil survey and land capability classification
with two methods being presented to you, the "weighted average" or the "dominant condition". This may appear to
be a simple question; however two different answers are presented with each having significant impacts.
I would like to start with some basic information, will keep it brief, and express a willingness to answer questions and
provide additional information or clarification at a later date.
1. Deschutes County Soil Survey was completed and published in 1992. The MOU defined the purpose, level of
detail or scale of mapping (1:24,000) and levels of intensity. There are three sections of the survey: Soil
Descriptions, Soil Maps, and Soil Interpretations.
2. The Soil Survey has been digitized and is referred to as the Web Soil Survey (WSS). This electronic copy is
considered the most current and accurate source for soils information.
3. NRCS conducts mapping by studying landscapes, associated landforms, and soils associated with those
landforms. This understanding is sufficient to predict the kinds of soils in an area and to determine its
boundaries and map unit composition using field observations, transects, and remote sensing. Map unit
composition is an average that has been observed throughout the extent of the soil survey. Map unit
components, including contrasting inclUSions, generally occur in a predictable pattern.
4. In Oregon, land use issues are primarily based on tax lot(s) or an area of interest, not landscapes.
5. The information you received for Section 11 in Tables 1-4 is from the WSS and based on two tax lots totaling 380
acres. Table 1-2 are based on the percentages of the map unit components. Tables 3-4 are based on the
dominant component of a map unit.
6. What you have not been provided from the WSS is a Warning Statement provided at the time of delineating the
tax lots. It states:
Warning: Soil Map may not be valid at this scale.
You have zoomed in beyond the scale at which the sail map for this area is intended to be used. Mapping of
soils is done at a particular scale. The soil surveys that comprise your AOI were mapped at 1:24K. The
design of map units and the level of detail shown in the resulting soil map are dependent on that map scale.
Enlargement of maps beyond the scale of mapping can cause misunderstanding of the detail of mapping and
accuracy ofsoil line placement. The maps do not show the small areas of contrasting soils that could have
been shown at a more detailed scale.
Table 2 (county) method uses map unit composition that was mapped at the landscape level.
Table 4 (alternative) uses a method that recognizes the map units limitations, risk of damage and the way it will
respond to management (lCe) that was mapped at the landscape level.

7. The 58C and 38B map units extend on the landscape outside the Section 11 site (Appendix A). The 58C unit is
837 acres on the landscape and 33.77 acres (4%) in "Section 11"; similarly, the 38B unit is 3,500+ acres on the
landscape and 56.12 acres «2%) in "Section 11". "Section 11" is presented at a scale of 1:10K, whereas the soil
survey was mapped at 1:24K. You would expect to find the approximate percentages of soils as described in the
WSS map unit descriptions at the 1:24K scale. To dissect a small portion (tax lot) from the landscape map unit
and expect to find each component equally represented is very unlikely and will result in inaccurate data. Both
systems presented to you at the 1:10K scale are based on the 1:24K landscape level mapping and data. As noted
in the warning statement the 1:10K map may not be valid (Appendix B). Please note on the landscape level map
1:24K (Appendix A, page 2) the warning statement is absent.
8. NRCS policy states: GM 430 Part 402.6, 11/1992 -Limitations on Use of Soil Survey Information
. a. Soil surveys seldom contain detailed site specific information and are not designed to be used as primary
regulatory tools in permitting or citing decisions, but may be used as reference sources. The soil survey
information is public information and may be interpreted by organizations, agencies, units of
governments, or others based on their own needs, however, they are responsible for the appropriate
application ofsoil survey information. Federal, state or local regulatory bodies are not to reassign to the
NRCS any authorityfor the decisions that they make. The NRCS will not perform any evaluations of soil
maps contained in published soil surveyor any supplemental soil mapping for purposes related solely to
state or local regulatory programs.
NRCS maps soils at the landscape level. Land use issues in Oregon are addressed by tax lot(s) or areas of
interest. Consequently, NRCS soil maps may be perfectly correct at the landscape level while a tax lot may
be. in part or entirely. a single map unit component or a contrasting inclusion.
From the WSS you can glean information to support the "weighted average" methodology as well as the
"Dominant condition" methodology, depending upon your land management purpose. The "weighted
average" will give you a more accurate determination of the content of the mapping unit, and the
"dominant condition" will give you the most reasonable method to manage the land under the original
purposes of the LCC system at the scale of mapping.
In summary, the soil survey is accurate at the scale of mapping and this is not a challenge to that fact. However, to
fully document the soils in the tax lot(s) or area of interest, a more detailed survey is prudent.
DSL's Soils Investigation for Stevens Road Tract (Section 11), dated 7/26/2011 was submitted to Deschutes County on
10/27/2011. During this interim period DLCD adopted Rules for HB 3647 on 10/1/2011. This report is sound and
scientifically based and consistent with DLCD report requirements, other than minor format and content
adjustments. This detailed Order 1 soils investigation's final analysis and results determined this 380 acre Stevens Rd
Tract is approximately 56% LCC 7/8 non-agricultural land and 44% LCC 6 agricultural lands.

crop; effective use of crop residue, bamyard manure,
and green manure crops; and harvesting that ensures
the smallest possible loss.
For yields of irrigated crops, it is assumed that the
irrigation system is adapted to the soils and to the
crops grown, that good-quality irrigation water is
uniformly applied as needed, and that tillage is kept to
a minimum.
The estimated yields reflect the productive capacity
of each soil for each of the principal crops. Yields are
likely to increase as new production technology is
developed. The productivity of a given soil compared
with that of other soils, however, is not likely to
change.
Cropsother than those shown in the table are grown
in the survey area, but estimated yields are not listed
because the acreage of such crops may be small. The
local office of the Natural Resources Conservation
Service or of the Cooperative Extension Service can
provide information about the management and
productivity of the soils for those crops.
Land Capability Classification
Land capability classification shows, in a general
way, the suitability of soils for most kinds of field
crops. Crops that require special management are
excluded. The soils are grouped according to their
limitations for field crops, the risk of damage if they are
used for crops, and the way they respond to
management. The criteria used in grouping the soils do
not include major and generally expensive landforming
that would change slope, depth, or other
characteristics of the soils, nor do they include
possible but unlikely major reclamation projects.
Capability classification is not a substitute for
interpretations designed to show suitability and
limitations of groups of soils for rangeland, for
woodland, and for engineering purposes.
In the capability system (24), soils are generally
grouped at three levels-capability class, subclass,
and unit. Only class and subclass are used in this
survey.
Capability classes, the broadest groups, are
designated by numerals I through VIII. The numerals
indicate progressively greater limitations and narrower
choices for practical use. The classes are defined as
follows:
Class I soils have few limitations that restrict their
use.
Class II soils have moderate limitations that reduce
the choice of plants or that require moderate
conservation practices.
Class III soils have severe limitations that reduce
the choice of plants or that require special
conservation practices, or both.
Class IV soils have very severe limitations that
reduce the choice of plants or that require very careful
management, or both.
Class V soils are not likely to erode but have other
limitations, impractical to remove, that limit their use.
Class VI soils have severe limitations that make
them generally unsuitable for cultivation.
Class VII soils have very severe limitations that
make them unsuitable for cultivation.
Class VIII soils and miscellaneous areas have
limitations that nearly preclude their use for
commercial crop production.
Capability subclasses are soil groups within one
class. They are deSignated by adding a small letter, e,
W; s, or c, to the class numeral, for example, lie. The
letter e shows that the main hazard is the risk of
erosion unless close-growing plant cover is maintained;
wshows that water in or on the soil interferes with
plant growth or cultivation (in some soils the wetness
can be partly corrected by artificial drainage); s shows
that the soil is limited mainly because it is shallow,
droughty, or stony; and c, used in only some parts of
the United States, shows that the chief limitation is
climate that is very cold or very dry. .
In class I there are no subclasses because the soils
of this class have few limitations. Class V contains
only the subclasses indicated by W; s, or c because
the soils in class V are subject to little or no erosion.
They have other limitations that restrict their use to
pasture, rangeland, woodland, wildlife habitat, or
recreation.
The capability classification of each map unit in this
survey area is given in table 5.
Prime Farmland
Prime farmland is one of several kinds of important
farmland defined by the U.S. Department of Agriculture.
It is of major importance in meeting the Nation's short
and long-range needs for food and fiber. Because the
supply of high-quality farmland is limited, the U.S.
Department of Agriculture recognizes that responsible
levels of govemment, as well as individuals, should
encourage and facilitate the wise use of our Nation's
prime farmland.
Prime farmland, as defined by the U.S. Department
of Agriculture, is land that has the best combination of
physical and chemical characteristics for producing
food, feed, forage, fiber. and oilseed crops and is
available for these uses. It could be cultivated land.
pastureland, forest land, or other land, but it is not

As requested, I have reviewed the Soils Investigation Report by Sage West, LLC of the Stevens Rood Tract located in T18S, R12E,
and Section 11 as it relates to the new "study area". The review was determined necessary as the boundary and size of the new
"study area" differs from the original 622 acre study area that was reduced to 380 acres . The new area is primarily the west half
of Section 11 that is west of the eastern boundary of the Gas Transmission Easement.
Dan Antonson, GIS Analyst ODSL, digitized the mapping units from the soil map completed by Sage West, LLC dated June 2010 for
the new study area . Data points, transect data and accuracy of soil boundary line placement was reviewed both in the office and
field. Minor adjustments to soil boundaries were made to four polygons based on field observation and updated on the ODSL
Stevens Rood Tract Map dated 7/25/2011 (attached).
Mapping unit descriptions and interpretations in the Soils Investigation Report, dated 7/6/2010, accurately describe conditions
existing in the new study area .

The inventory and ana lysis of this 380 acre study area in the Stevens Road Tract determined that approximately 56% is land
Capa bility Class 7 and 8, and 44% is land Capability Class 6. This study area in the Stevens Road Tract as defined in OAR 660-033
0020 is predominantly non-agricultural land.

Background:
Geology: This study area consists of basalt lava flows. The lava flows near Bend issued from vents
in Newberry Volcano and High Cascades volcanoes. These flows are among the youngest geologic
surfaces in the central Oregon area having been laid down less than 2 million years ago. A mantle
of volcanic ash was deposited during the eruption of Mt. Mazama over the basalt lava flows. Soils
on these flows are ashy and sandy in texture. Varying amounts of volcanic ash have been eroded
from rock outcroppings and redeposited in depressions. A deep depression in the southeast corner
was filled with alluvial sediments of ashy material to form a large area of surficial deposits of ash,
sand and gravel.
Soils : Soils associated with these geologic formations and associated landforms are the Deskamp
soil in depressions, Gosney soil on the slightly higher positions along the margins of the depressions
and rock outcroppings and the Clovkamp soil on the surficial deposits.
N RCS mapping shows six soil mapping units on this property, three consociations and three
complexes. Consociations are a deep ashy soil (Clovkamp) and a moderately deep, ashy soil
(Deskamp) over a lithic contact of basalt. The complexes are composed predominantly of
moderately deep, ashy soils (Deskamp and Wanoga) and shallow, ashy soils (Gosney and Fremkle)
over a lithic contact of basalt; and rock outqop.
Summarized in Table 1 are soil properties and interpretive groupings that are important for
determining the presence and predominance of agricultural land on this tract.

Methodology:
The Soil Survey of Upper Deschutes River Area, Oregon, including parts ofDeschutes, Jefferson, and
Klamath Counties was mapped at two levels of intensity. At the less detailed level (Order 3), map
units are mainly complexes. The average size of delineations for most management purposes was
160 acres. At the more detailed level (Order 2), map units are mainly consociations and complexes.
The average size of delineations for purposes of management was 40 acres and the minimum size
was 5 acres. Most of the land mapped at the more detailed level is used as irrigated and non
irrigated cropland. Inclusions of contrasting soils or miscellaneous areas are described in the map
unit if they are a significant component of the unit. The NRCS soil survey (Order 3) on this study
area was reviewed on-site and determined to be predominantly accurate at the scale of mapping.
The soil/landscape relationships were accurate. Soil boundary placements were general. At the
Order 3 level of mapping, miscellaneous land types were not mapped or identified as inclusions. In
addition, original placement of soil boundary lines by field soil scientists on aerial photos are often
modified and straightened during the map digitizing process.
An Order 1 soil survey is prudent to accurately define soils, mapping units, and miscellaneous areas
and accurately locate their boundaries for detailed planning purposes. Methods to investigate the
soil included the use of shovel, auger, probe and backhoe. Point observations and transects were
used to identify soil characteristics and map unit composition.
Findings:
This parcel consists of developed and undeveloped areas. The Stevens Road Tract is not irrigated
and has no water rights. For the purpose of this study the developed areas were separated into
five distinct mapping units that are miscellaneous land types. They are referenced as Access Road,
Gas Transmission Easement, Landfill, Mined/Fill Area, and Stevens Road. The landfill was mapped
using existing conditions detailed in the Initial Site Assessment Report of the Former Deschutes
County Landfill by PBS Environmental and Engineering, Bend, OR.
The undeveloped areas were separated into four soil mapping units. They are referenced as
Clovkamp loamy sand, 0-3% slopes, Deskamp-Gosney complex, 0-8% slopes, Gosney-Rock outcrop
complex, 0-8% slopes and Gosney-Rock outcrop complex, 8-15% slopes. All areas occur within
Section 11 and Tax Lots 1700 and 1800.
Developed Land:
Access Road (AR): This miscellaneous land type is located on the eastern boundary of the
tract. It provides a north/south access along an existing overhead power line. It is graded
and graveled. Revised soil mapping accurately describes and locates this feature. (LCC 8)
Gas Transmission Easement: (GTE): This miscellaneous land type is located in the central
portion of the tract. The easement enters the tract in the northeast quarter and extends
to the south central boundary. This area has been highly disturbed by excavations and fills
during the installation of utilities. Revised soil mapping accurately describes and locates
the extent of this easement area. (LCC 8)
I landfill elF): This miscellaneous land type is known as the former Arnold landfill.
Approximate extent of the former Arnold landfill was digitized from aerial photographs
obtained from the Department of State lands. Revised soil mapping accurately describes
I the extent of this landfill. (LCC 8):!

Mined/Fill Area (MFA): These areas were excavated with soil material removed from the
site. Material was used as fill and/or bedding for the gas transmission line. In addition,
other disturbed areas have been filled with off-site material of mixed soil, gravel, stones
and boulders. These areas are now considered "mined/filled land" and are miscellaneous
land types. Revised soil mapping accurately locates the extent of these mined and filled
areas. (LCC 8)
Stevens Road (SR): This miscellaneous land type is located on the northern boundary of
the tract. It enters at the northeastern corner and extends west along the northern
boundary to the northwest quarter. It is an improved and paved county road. Revised soil
mapping accurately describes this feature. (LCC 8)
Undeveloped Land:
This area includes lands that have not been significantly altered. Most areas are in native
vegetation consisting of western juniper, bitterbrush, big sagebrush, rabbitbrush and
Idaho fescue.
A mantle of volcanic ash was deposited during the eruption of Mt. Mazama over the basalt
lava flows. Soils on these flows are ashy and loamy sand in texture. Varying amounts of
volcanic ash have been eroded from rock outcroppings and redeposited in depressions.
Deskamp and Clovkamp soils are in these depressions and Gosney soils are in the slightly
higher positions along the margins of the depressions and rock outcroppings.
Revised soil mapping accurately delineates the following mapping units.
Clovkamp loamy sand, 0-3% slopes (CA): Clovekamp soils are on lava plains and are
volcanic ash over gravelly alluvium. Slopes are 0 to 3%. The surface layer is loamy sand
over a strongly contrasting extremely gravelly sand textural stratification at 35 to 50
inches. (LCC 6)
Deskamp-Gosney complex, 0-8% slopes (DGB): This mapping unit is on lava plains. Soils
are volcanic ash over basalt. Slopes are 0 to 8%. The Deskamp and similar soils are 50
percent and Gosney and similar soils are 35 percent. The Deskamp soil is loamy sand and
gravelly loamy sand, 20 to 40 inches deep over basalt. The Gosney soil is stony loamy
sand, 10 to 20 inches deep over basalt. (LCC 6)
Gosney-Rock outcrop complex. 0-8% slopes (GRB): This mapping unit is on lava plains.
Soils are volcanic ash over basalt. Slopes are 0 to 8%. The Gosney and similar soils are 60
percent and rock outcrop is 20 percent. The Gosney soil is very stony loamy sand, 10 to 20
inches deep over basalt. (LCC 7)
Gosney-Rock outcrop complex. 8-15% slopes (GRC): This mapping unit is on lava plains.
Soils are volcanic ash over basalt. Slopes are 8-15%. The Gosney and similar soils are 50
percent and rock outcrop is 25 percent. The Gosney soil is very stony loamy sand, 10 to 20
inches deep over basalt. (LCC 7)

EFU to MUA-lO. These applications were considered by a Deschutes County Hearings Officer last spring. On July 10, 2012, the
Hearings Officer recommended approval to the Board of County Commissioners (BOCC).
On September 24, the BOCC held a public hearing on the
applications, closed the oral public hearing on that same day
but left the written record open until October 10, 2012 for
responses to information presented at the hearing and until
October 26, 2012 for the applicant's final rebuttal with no new
evidence. During the applicant's final rebuttal period, the
applicant submitted new evidence regarding the soil
classification of the subject property. New evidence submitted
by the applicant is allowed to be included in the record if all
other parties have a due process right to respond to the
evidence. On November 5, the BOCC decided to re-open the
public hearing on this issue. On November 19, the BOCC
approved Order No . 2012-038 finding that clarifying how to
determine the soils classification is paramount to the final
decision in this case as well as 'future cases. Therefore, the
BOCC re-opened the record and will conduct a public hearing
on this issue on Monday, December 3, 2012 at 10 :00 a.m .

Statewide Planning Goal 3, Agriculture states that
lands classed by the Natural Resource
Conservation Service (NRCS) as predominantly 1-6 soils in
Eastern Oregon are "agricultural land."
Table 1 shows the amount of land mapped for each soil
complex (a soil complex means there are different soil types and classifications) by NRCS, and the amount of land designated as
"agricultural land," "non-agricultural land," and "unknown/mixed" soils.

Under state law, if a property is predominately (over 50 percent) comprised of Class 1-6 soils in Eastern Oregon, then the property
shall be designated agricultural land. If a property is not predominately agricultural land, then it may be considered for another
designation based on established criteria. Therefore, the key question before the BOCC is to determine the method to interpret the
soils information .
Table 2 illustrates County planning staff's method to interpret the soils classifications. Based on this analysis/methodology, 51.5
percent of the land is non-agricultural land and 37.8 percent is agricultural land.

Tables 3 and 4 provide an alternative method to interpreting the soils classifications. Specifically, this method determines the
majority soil classification for each soil complex and applies the majority soil type to £!! the soils in the complex. For example, soil
complex 38B is comprised of SO percent Class 6 soils, 35 percent Class 7 soils, and 15 percent are unknown or mixed soils. Based on
this analysis, the majority soil type (SO percent) is Class 6. Therefore, Class 6 is applied to the entire 203.83 acres.

Dear Douglas:
Subject: Soil inquiry for map units and soil types in Section II, T1SS, R12E -Based on
NRCS soil information on Web Soil Survey (WSS).
The soil map units in this section are dominated by map units 3SB and 5SC. These two map
unit account for about 90% of the section. Both map units are a complex of two or more
dominant soil types; Deskamp soil, Gosney soil, and in map unit 5SC a component of Rock
outcrop. The two map units are;
3SB-Deskamp-Gosney complex, 0 to S percent slopes
5SC-Gosney-Rock outcrop-Deskamp complex, 0 to 15 percent slopes
The original soil survey was mapped at a scale of 1:24,000. At this mapping scale, soils can
occur in such an intermingled pattern that each soil type cannot be mapped separately.
When this occurs the kind of map unit we use to indicate this pattern is called a complex,
and the dominant soil types are identified along with a estimated percent composition of
each soil type in the map unit. Given this scale of mapping and the need of users, the NRCS
does recognize the need for onsite soil investigations for a more detailed inventory of the
soil types, and if the scale is detailed enough, the soil types identified in a complex could
perhaps be delineated separately.
A land capability class (LCC) is assigned to each soil type in a map unit.
In map unit 3SB; the Deskamp soil type has a LCC of 6 and it comprises 50% of the map
unit area. The Gosney soil type has a LCC of 7 and it comprises 35% of the map unit area.
In map unit 5SC; the Gosney soil type has a LCC of 7 and it comprises 50% of the map unit
area. The Rock outcrop component has a LCC ofS and it comprises 25% ofthe map unit
area. The Deskamp soil type has a LCC of 6 and it compromises 20% of the map unit area.
This LCC placement and percent composition of the soil type in the map unit is available on
WSS.

So to determine the percent of an area having land capability class, 6, 7, or 8 the following
example could be used. First delineate out the area of interest and determine the acreage
of each map unit in that area of interest. Second would then be to determine the acres in
each LCC in each map unit. Then sum the acres and determine the percentage of each LCC
for the total area.
EXAMPLE:
In section 11, T18S, R12E--we delineate our area of interest and say it is 400 acres. We
then determine that 100 acres of the area is map unit 38B and 300 acres of the area is map
unit 58e.
100 acres
Is map unit 38B-with 50% of the area being Deskamp soil (LCC 6) and 35% of the area
being Gosney soil (LCC 7).
300 acres
Is map unit 58C-with 50% of the area being Gosney soil (LCC 7), 25% being Rock outcrop
(LCC 8), and 20% being Deskamp soil (LCC 6).
Determining the percent land capability class for the area;
38B-50% Deskamp soil (LCC 6) of 100 acres==50 acres LCC 6
-35% Gosney soil (LCC 7) of 100 acres====35 acres LCC 7
58C-50% Gosney soil (LCC 7) of 300 acres===150 acres LCC 7
-25% Rock outcrop (LCC 8) of 300 acres==75 acres LCC 8
-20% Deskamp soil (LCC 6) Of 300 acres==60 acres LCC 6
LCC 6=50 acres + 60 acres===110 acres
LCC 7=35 acres + 150 acres==185 acres
LCC 8=75 acres============75 acres
TOTAL===================370 acres
110 acres LCC 6 divided by 370 acres x 100==about 30% of area in LCC 6
185 acres LCC 7 divided by 370 acres x 100==about 50% of area in LCC 7
75 acres LCC 8 divided by 370 acres x100===about 20% of area in LCC 8
Conclusion in this example is that about 70 percent of the area is in Land Capability Class 7
and 8.
NOTE; although our area of interest is 400 acres, only 370 acres are comprised ofthe major
map unit soil types (Deskamp, Gosney and Rock outcrop). The remaining 30 acres would
consist of minor components or what is typically referred to as inclusions. These
inclusions depending on the map unit could range have a capability class of 4,6, 7, or 8
depending on the soil type. But due to the limited acreage the impact on the results would
be minimal.

Bend, Oregon 97701
Dear Liz :
This letter is in response to your inquiry about the letter I sent to Douglas Parker (Oregon
Department of State Lands) on October 3,2012. This letter to Doug addressed a procedure to
determine the percent of an area having land capability class (LeC) 6, 7, and 8.
The procedure and example in the letter to Doug, addresses soil map units that are a complex
of two or three names soil types. In the letter and example a weighted a verage methodology
was used to determine the percent o f an area in each of the land capability classes. This
methodology is a valid procedure for determining the percent area in each capability class .
There is another methodology for determining the dominant land capability class for an area .
This method is based on the dominant condition . This is the method of determination used in
Web Soil Survey. The weighted average methodology is not an available procedure for use in
Web Soil Survey. With the dominant condition methodology, the soil components percent in a
map unit having the same Lee soil component are added together and the highest percent Lee
is what is assigned to the entire map unit. Using this method, a map unit such as 38B
Deskamp -Gosney complex, 0 to 8 percent slope, which is comprised of 50% Deskamp soil
with Lee to 6, and 35% Gosney soil with Lee of 7; the entire map unit area of 38B is identified
as Lee 6 since the Deskamp soil is dominant. The Gosney soil and its associated Lee 7 is not
accounted for in this methodology .
Example for dominant condition methodology; we have an area of interest that is 375 acres
in size, of this 375 acres ; 215 acres are in map unit 38B Deskamp-Gosney complex and 160
acres are in map unit 58B Gosney-Rock outcrop-Deskamp complex .
38B Deskamp soil is 50% of the area with Lee 6 .
38B Gosney soil is 35% of the area with Lee 7.
58e Gosney soil is 50% of the area with Lee 7.
58e Rock outcrop is 25% of the area with Lee 8.
58e Deskamp soil is 20% of the area with Lee 6.
In the above example the dominant condition methodology would assign all acreage of map
u nit 38B to Lee 6 and a ll acres of map unit 58e to Lee 7. Thus far our area of interest which
is 375 acres, 215 acres are in Lee 6 (are of map unit 38B) and 160 acres are in Lee 7 (area of
map unit 58C). Therefore, about 57% of the area is Lee 6 and about 42% of the area is Lee 7.
Over 50% of our area o f interest is Lee 6, using the domjnant condition methodology .
In the same example the weighted average methodology would identify the 215 acres of
map unit 38B as; 107 acres of Deskamp soil (50%) and 75 acres of Gosney soil (35%). It would
identify the 160 acres of map unit 58e as; 80 acres of Gosney soil (50%) Lee 7, 40 acres of
Rock outcrop (25%) Lee 8, and 32 acres of Deskamp soil (20%) Lee 6.
Thus for our area of interest we have:
Helping People Help the L8nd
An Equal Opportunity Provider and Employer
(107 + 32) = 139 acres of Deskamp soil with LCC 6
(75 + 80) = 155 acres of Gosney soil with LCC 7
(40) = 40 acres of Rock outcrop with LCC 8
Total acres are 324 rather than the 375 acres because each map unit contains 15% minor soil
components that are not identified to a LCC.
Thus:
139 acres of our 324 acres is in the LCC 6 which is about 42% of the area
155 acres of our 324 acres is in LCC 7 which is about 47% of the area
40 acres of our 324 acres is in the LCC 8 which is about 12% of the area
Ove r 50% of our area of int e r e st is i n the LC C 7 an d 8 u s ing the w eighte d a verage m ethodology.
Therefore, it is critical to identify a method
to be used and then apply the method consistently when making determination, within a
county, state, or jurisdiction.
The dominant condition method results can be generated using Web Soil Survey. It is
relatively quickly determined and is highly consistent. The weighted average method results
must be but all information to do the manual calculations is in Web Soil
I hope this letter and examples helps to explain how two different
results can occur for the same area of interest. Please get in touch with me if you have
questions.

Dominant Condition vs. Weighted
Average Methods of Assessing Soil
Classification
What are the key issues?
•When using the NRCS Web Soil Survey to
determine whether a majority of soils on a
property are Class VI or better, should the soils
classification method used by the NRCS Web
Soil Survey (dominant condition) or some
other method be used by the County?
•If another method is used, what is that
method and how will it be applied?
What soils information can be used to
approve DSL’s application?
•Land classification information from NRCS
–NRCS Internet Soil Survey
•NRCS Internet Soil Surveys provided by Newland
–Information produced by the National Cooperative
Soil Survey operated by the NRCS of the USDA as
of January 2, 2012
•DSL Soils map based on NRCS Soil Survey
What soils information may not be
used in making a decision?
•More detailed soils data provided by Sage
West, LLC (Roger Borine) unless DLCD
approves the Sage West LLC soils report.
–“[T]his report provides and documents more
detailed data on soils maps and soil survey at the
published level of detail.” p. 1, Sage West LLC

What is a map unit?
•A map unit is a very large area of land shown
on the NRCS Soil Survey. A small part of the
unit will be found on a lot.
•One soil name is assigned to each unit.
What is a complex?
•A complex is a map unit that contains soils
that are a mix, within a map unit, of more
than one known soil type.
•The soil map unit includes the word
“complex.”
What is an example of a soil complex
found on the DSL property?

What is a Contrasting Inclusion?
•A contrasting inclusion is a soil of a type that is
not known or is not identified by the NRCS Soil
Survey.
•No Soil Class is provided for contrasting
inclusions by NRCS.
•Contrasting inclusions can be up to 15% of a
property being considered for non-agricultural
land designation.
What is the Dominant Condition
Method of Soil Classification?
•All soils in a single map unit are assigned one
soil class.
•The soil class of the dominant soil type in a
map unit is used for all soil found in the
mapping unit.
•This is the method used by the NRCS Web Soil
Survey.
•This is the method used by Sage West, LLC
(Roger Borine).
What is the History of the Dominant
Condition Test?
•In the past, the dominant condition test was
the only test used by NRCS to rate soils found
in map units.
•Now, NRCS Soil Surveys provide ratings for
each soil found in a map unit so it is possible
to use a weighted average method.
What is the Weighted Average
Method?
•The weighted average method:
–Calculates the land area within a soil map unit on
the DSL property.
–Determines the percentage of each soil found in a
map unit using NRCS charts.
–Multiplies the percentage x total acres in the map
unit.
–Applies soil class to acres of each soil type found
in a map unit.
What Soil Class Is a 38B Soil Using Each
Method?
Dominant Condition
•100% Class 3 irrigated
•100% Class 6 nonirrigated
Weighted Average
•50% Class 3 irrigated
•35% Class 4 irrigated
•15% Unknown
•50% Class 6 nonirrigated
•35% Class 7 nonirrigated
•15% Unknown
Comparison of Merits of Methods
Dominant Condition
•Easy to apply
•Broad brush
•Calculated by Web Soil
Survey; not by applicant
•Consistent with State law
that allows use of Web Soil
Survey
•All unknown soils assigned a
soil class
Weighted Average
•Complicated
•Closer to accurate reflection
of soil conditions
•Not used by Web Soil
Survey
•Unclear what soil class to
apply to unknown soils
Comparison of How Methods
Handle Unknown Soils
Dominant Condition
•The soil class of the
dominant soil type is
assigned to the contrasting
inclusion.
Weighted Average
•Different approaches have
been taken by County staff
and Thor Thorson. Other
methods may be better.
•Deschutes County must
decide how to handle
unknown soils (contrasting
inclusions).
How have Contrasting Inclusions been
Handled by County Staff?
•No soil class was assigned to contrasting
inclusions in soil complexes.
•Inclusions found in all other soils are given a
soil class.
•Staff required a majority of entire property to
be Class 7 or 8.
•Effect is that all inclusions in complexes are
always Class 6 or better agricultural soil.
County Method
Soil Class Total Acres Percentage of 363
Acres
Ag Land v. Non-Ag
Land
Class 6 137.17 acres 37.8% 37.8% Ag Land
Class 7 147.90 acres 40.7% 51.5% Non Ag Land
Class 8 39.07 acres 10.8%
Inclusions 38.86 acres 10.7% 10.7% Unknown
Thorson Method (11/1/12)
•Assumed a DSL Property size of 375 acres.
(example only; not all soil types considered)
•A soil class was determined for soils on 324
acres; the areas of soil inclusions were
excluded from the DSL property.
•The percentage of land that is Agricultural
Land was based on a property size of 324
acres rather than 375 acres.
Problems with Thorson Approach
•State law requires a majority of the entire DSL
property (375 acres in Thorson example) to be
Class 7 or 8 nonagricultural soils.
•Removing contrasting inclusions from soil
complexes gives greater weight to soils that
are not a complex (because their areas of
inclusions are counted).
–Example: 34C, Deschutes 85%; Inclusions 15%
100 acres Deskamp-Gosney complex
With Inclusions; 100 acres Deschutes
Soil Types
Deskamp 50% 6
Gosney 30% 7
Inclusions 15%
Deschutes 100% 4
100 acres Deskamp-Gosney complex,
Omit Inclusions; 100 acres Deschutes
Soil Type
Deskamp 50% 6
Gosney 35% 7
Inclusions
Deschutes 100% 4
Better Approaches?
•Assign a soil class to contrasting inclusions
based on dominant condition
–38B dominant condition Class 6
–58C dominant condition Class 7
•Determine the ratio of soil classes to each
other and apply to contrasting inclusions
–58C = 50% Class 6 : 35% Class 7 or 10 to 7 ratio
•10/17th x acres of inclusions = ___ acres Class 6
•7/17th x acres of inclusions = ___ acres Class 7
Advantages of Better Approaches
•Each method accounts for the entire property.
•Each mapping unit is given the correct weight
in determining the percentage of property
that is Class 6 or better soil.
