Preliminary Drainage Report 1
I. GENERAL LOCATION AND DESCRIPTION
A. Location
1. Vicinity Map
2. The project site is located in the southwest quarter of 15, Township 7 North, Range
69 West of the 6th Principal Meridian, City of Fort Collins, County of Larimer, State of
Colorado.
3. The project site is located just southwest of the intersection of South Shields St. and
West Elizabeth Street.
4. The project site lies within the Old Town Master Drainage Basin. Per the Old Town
Master Drainage Plan, onsite detention is required. Onsite detention is typically
required for the runoff volume difference between the 100-year developed inflow rate
and the 2-year historic release rate. However, based on discussion with City Staff, an
overall allowable release rate of 5.0 cfs has been decided for this site. Please see
further discussion in Section IV.B, below.
5. LID water quality treatment will be provided on site, as described in further detail
below.
Saint John XXIII and Lombardy Student Housing
Preliminary Drainage Report 2
6. As this is an infill site, much of the area surrounding the site is fully developed.
7. Offsite flows enter the site from the north and west. We have defined three offsite
basins as shown in the Historic Drainage Exhibit provided in Appendix A. Further
discussion of these basins and flow quantities are provided below.
B. Description of Property
1. The development area is roughly 6.0 net acres.
Figure 1 – Aerial Photograph
2. The subject property is currently composed of existing buildings, and landscaped
areas. Existing ground slopes are mild to moderate (i.e., 1 - 3±%) through the
interior of the property. General topography slopes from west to east.
3. According to the United States Department of Agriculture (USDA) Natural Resources
Conservation Service (NRCS) Soil Survey website:
http://websoilsurvey.nrcs.usda.gov/app/WebSoilSurvey.aspx,
the majority of the site consists of Nunn Clay Loam, which falls into Hydrologic Soil
Group C.
4. The proposed project site plan is composed of the development of a commercial and
student housing development with amenities. Associated site work, water, and sewer
lines will be constructed with the development. Onsite water quality treatment is
proposed and will consist of several features which are discussed in Section IV,
below.

C. Floodplain
1. The project site is not encroached by any FEMA 100-year floodplain, please see
Appendix E for a copy of FIRM Map Number 08069C0978G (Revised 5/2/2012).
However, the City-designated W. Elizabeth Street flood fringe does encroach along the
northern border of the site. The CSU Underpass LOMR has been obtained from the
City of Fort Collins, we and have utilized the data for establishing base (100-year)
flood elevations through the site.
Figure 3 –Area Floodplain Mapping
2. Critical Facilities are not allowed in the floodplain.
3. A City of Fort Collins CLOMR/LOMR process will be undertaken to reflect the fill to be
placed on the site. It is anticipated that the fill will effectively shift the 100-year flood
fringe to the north, putting the majority of the site outside of the flood fringe. A
CLOMR/LOMR will show this shift in the flood fringe, and will effectively re-map the
City flood zone such that all proposed buildings will no longer be subject to Chapter
10 of City Code.
4. Three of the four proposed buildings are currently shown in the W.Elizabeth Flood
Fringe. The base (100-year) flood elevation in the vicinity of the west building is
5030.20 (NAVD 88). This flood elevation was interpolated at the upstream (west)
corner of the proposed west building.
5. The base (100-year) flood elevation in the vicinity of the middle building is 5029.00
(NAVD 88). This flood elevation was interpolated at the upstream (west) corner of
the proposed west building.
6. The base (100-year) flood elevation in the vicinity of the proposed east building is
5026.90 (NAVD 88). This flood elevation was interpolated at the upstream (west)

corner of the proposed west building.
7. The vertical datum utilized for site survey work is the City of Fort Collins Benchmark
#20-97 (Elevation=5050.15; NAVD 88).
8. It is noted that some of the surrounding developments have used the NGVD 29
(unadjusted) datum. The conversion from NAVD 88 to NGVD 29 (unadjusted) datum
is -3.18-ft.
9. Foundation for the east structure will be a combination of slab on grade and a
basement foundation. The foundation for the middle and west structure will be slab
on grade.
10. The current effective hydraulic model for the Elizabeth Street underpass LOMR was
obtained from the City of Fort Collins (HEC-RAS file: “Elizabeth_West_04_2018.prj”)
in February of 2019. Preliminary modeling has been conducted by Northern
Engineering reflecting the proposed fill to be placed within the existing flood fringe in
advance of the CLOMR report that will be submitted subsequent to this report. Table
1, below, summarizes results of preliminary modeling, based on the currently
proposed site plan and fill within flood fringe. As seen in this table, no-rise in 100-
year water surface elevation will occur with the currently proposed site plan and fill
within flood fringe. Hence, there will be no impact to neighboring properties due to
the proposed fill.

Preliminary Drainage Report 6
11. It is understood that the CLOMR will need to be completed prior to site grading and
an approved LOMR will be required prior to the release of any building permits for
structures that would not meet the current regulatory requirements.
12. Please see Appendix F, for preliminary HEC-RAS Modeling output.
II. DRAINAGE BASINS AND SUB-BASINS
A. Major Basin Description
1. The project site lies within the Old Town Master Drainage Basin. Onsite detention is
typically required for the runoff volume difference between the 100-year developed
inflow rate and the 2-year historic release rate. However, based on discussion with
City Staff, an overall allowable release rate of 5.0 cfs has been decided for this site.
Please see further discussion in Section IV.B, below.
B. Sub-Basin Description
1. The subject property historically drains overland from the west to the east. There is
an existing detention area within the existing John XXIII campus site parking area.
Also, there is a small existing parking lot detention area just east of the campus
parking area. Ultimately, release from these ponds is directed into the adjacent
Shields Street Right of Way.
2. A more detailed description of the project drainage patterns is provided below.
III. DRAINAGE DESIGN CRITERIA
A. Regulations
There are no optional provisions outside of the FCSCM proposed with the proposed
project.
B. Four Step Process
The overall stormwater management strategy employed with the proposed project utilizes
the “Four Step Process” to minimize adverse impacts of urbanization on receiving waters.
The following is a description of how the proposed development has incorporated each
step.
Step 1 – Employ Runoff Reduction Practices
Several techniques have been utilized with the proposed development to facilitate the
reduction of runoff peaks, volumes, and pollutant loads as the site is developed from the
current use by implementing multiple Low Impact Development (LID) strategies including:
Paver System with StormTech Chambers
Sand Filter
Step 2 – Implement BMPs That Provide a Water Quality Capture Volume (WQCV) with
Slow Release
The efforts taken in Step 1 will facilitate the reduction of runoff; however, urban
development of this intensity will still generate stormwater runoff that will require
additional BMPs and water quality. The majority of stormwater runoff from the site will
ultimately be intercepted and treated using LID treatment methods prior to exiting the site.
Saint John XXIII and Lombardy Student Housing
Preliminary Drainage Report 7
Step 3 – Stabilize Drainageways
There are no major drainageways within the subject property. While this step may not
seem applicable to proposed development, the project indirectly helps achieve stabilized
drainageways nonetheless. By providing water quality treatment, where none previously
existed, sediment with erosion potential is removed from downstream drainageway
systems. Furthermore, this project will pay one-time stormwater development fees, as
well as ongoing monthly stormwater utility fees, both of which help achieve City-wide
drainageway stability.
Step 4 – Implement Site Specific and Other Source Control BMPs.
The proposed project will improve upon site specific source controls compared to historic
conditions:
A portion of the site will be treated via a paver system.
StormTech chambers will receive the majority of onsite runoff; an isolator row will
provide LID treatment, providing filtration of suspended solids.
C. Development Criteria Reference and Constraints
The subject property is surrounded by currently developed properties. Thus, several
constraints have been identified during the course of this analysis that will impact the
proposed drainage system including:
Existing elevations along the property lines will generally be maintained.
As previously mentioned, overall drainage patterns of the existing site will be
maintained.
Elevations of existing downstream facilities that the subject property will release to
will be maintained.
Existing flows from the north and west will be safely conveyed through the
proposed site.
D. Hydrological Criteria
1. The City of Fort Collins Rainfall Intensity-Duration-Frequency Curves, as depicted in
Figure RA-16 of the FCSCM, serve as the source for all hydrologic computations
associated with the proposed development. Tabulated data contained in Table RA-7
has been utilized for Rational Method runoff calculations.
2. The Rational Method has been employed to compute stormwater runoff utilizing
coefficients contained in Tables RO-11 and RO-12 of the FCSCM.
3. Three separate design storms have been utilized to address distinct drainage
scenarios. A fourth design storm has also been computed for comparison purposes.
The first design storm considered is the 80th percentile rain event, which has been
employed to design the project’s water quality features. The second event analyzed is
the “Minor,” or “Initial” Storm, which has a 2-year recurrence interval. The third
event considered is the “Major Storm,” which has a 100-year recurrence interval.
The fourth storm computed, for comparison purposes only, is the 10-year event.
4. No other assumptions or calculation methods have been used with this development
that are not referenced by current City of Fort Collins criteria.
E. Hydraulic Criteria
1. As previously noted, the subject property maintains historic drainage patterns.
2. All drainage facilities proposed with the project are designed in accordance with
Saint John XXIII and Lombardy Student Housing
Preliminary Drainage Report 8
criteria outlined in the FCSCM and/or the Urban Drainage and Flood Control District
(UDFCD) Urban Storm Drainage Criteria Manual.
3. As discussed above, the subject property is located in a City designated 100-year
floodplain. However, a City CLOMR/LOMR will be undertaken to remove proposed
buildings from the flood fringe.
4. The proposed project does not propose to modify any natural drainageways.
F. Modifications of Criteria
1. The proposed development is not requesting any modifications to criteria at this time.
IV. DRAINAGE FACILITY DESIGN
A. General Concept
1. The main objectives of the project drainage design are to maintain existing drainage
patterns, and to ensure no adverse impacts to any adjacent properties.
2. LID treatment will be provided using a combination of a paver system and StormTech
chambers.
3. Drainage patterns anticipated for drainage basins shown in the Drainage Exhibit are
described below.
Basin 1
Basin 1 is primarily composed of landscaped areas, and a small amount of paved
area. This basin will generally drain via sheet flow directly into adjacent City Park
Avenue and University Avenue. Runoff from this basin will not be detained; therefore,
the overall site release rate has been reduced to compensate for this undetained
release.
Basin 2
Basin 2 is primarily composed of landscaped areas, proposed buildings and amenities.
This basin will drain via sheet flow and roof drain system primarily to an access drive
running along the north side of the basin. Access drive curb and gutter will direct
runoff into the onsite chamber system. Runoff from the entirety of Basin 2 basin will
be detained and treated in the onsite chamber system, and released into the existing
storm line system in Shields St.
Basin 3
Basin 3 is composed of landscaped areas and sidewalk. This basin will generally
drain via sheet flow directly into adjacent Shields Street and University Avenue.
Runoff from this basin will not be detained; therefore, the overall site release rate has
been reduced to compensate for this undetained release.
Basins OS1, OS2, and OS3
Basins OS1, OS2, and OS3 are composed of offsite drainage areas to the north of the
site. These areas are fully developed with portions of the basins consisting of
commercial development and paved parking areas. An offsite basin exhibit has been
provided in the appendix, as well as peak 100-year discharge calculations.
A full-size copy of the Drainage Exhibit can be found in the Map Pocket at the end of
this report.
Saint John XXIII and Lombardy Student Housing
Preliminary Drainage Report 9
B. Specific Details
1. One onsite detention facility will be provided within the site. A StormTech
chamber system will provide detention as well as LID treatment in the Isolator
Row of the chamber system, primarily treating drainage Basin 2.
2. Based on calculations provided in Appendix B, the required detention volume
for the proposed chamber system is 1.471 Ac-Ft.
3. A total combined release rate has been determined for the proposed detention
facilities has been set at 5.0 cfs. This release rate was determined in a
meeting conducted in April of 2019 with City of Fort Collins Staff, and was
based on the current master plan and SWMM model for the area.
4. The primary LID treatment for the site will occur within the StormTech
chamber system. Please refer to Appendix C for an LID Exhibit and all
pertinent calculations and information. As shown in Appendix C, the proposed
LID treatment design exceeds the 75% treatment requirement.
5. Stormwater facility Standard Operating Procedures (SOP) will be provided by
the City of Fort Collins in the Development Agreement.
V. CONCLUSIONS
A. Compliance with Standards
1. The drainage design proposed with the proposed project complies with the City of Fort
Collins’ Stormwater Criteria Manual.
2. The drainage design proposed with this project complies with requirements for the Old
Town Master Drainage Basin.
3. The drainage plan and stormwater management measures proposed with the
proposed development are compliant with all applicable State and Federal regulations
governing stormwater discharge.
B. Drainage Concept
1. The drainage design proposed with this project will effectively limit any potential
damage associated with its stormwater runoff by providing detention and water
quality mitigation features.
2. The drainage concept for the proposed development is consistent with requirements
for the Old Town Master Drainage Basin.

APPENDIX D
Erosion Control Report
Saint John XXIII and Lombardy Student Housing
Preliminary Erosion Control Report
PRELIMINARY EROSION CONTROL REPORT
A comprehensive Erosion and Sediment Control Plan (along with associated details) will be included
with the final construction drawings. It should be noted, however, that any such Erosion and
Sediment Control Plan serves only as a general guide to the Contractor. Staging and/or phasing of
the BMPs depicted, and additional or different BMPs from those included may be necessary during
construction, or as required by the authorities having jurisdiction.
It shall be the responsibility of the Contractor to ensure erosion control measures are properly
maintained and followed. The Erosion and Sediment Control Plan is intended to be a living
document, constantly adapting to site conditions and needs. The Contractor shall update the
location of BMPs as they are installed, removed or modified in conjunction with construction
activities. It is imperative to appropriately reflect the current site conditions at all times.
The Erosion and Sediment Control Plan shall address both temporary measures to be implemented
during construction, as well as permanent erosion control protection. Best Management Practices
from the Volume 3, Chapter 7 – Construction BMPs will be utilized. Measures may include, but are
not limited to, silt fencing along the disturbed perimeter, gutter protection in the adjacent roadways
and inlet protection at existing and proposed storm inlets. Vehicle tracking control pads, spill
containment and clean-up procedures, designated concrete washout areas, dumpsters, and job site
restrooms shall also be provided by the Contractor.
Grading and Erosion Control Notes can be found on the Utility Plans. The Final Plan set will
contain a full-size Erosion Control sheet as well as a separate sheet dedicated to Erosion Control
Details. In addition to this report and the referenced plan sheets, the Contractor shall be aware of,
and adhere to, the applicable requirements outlined in the Development Agreement for the
development. Also, the Site Contractor for this project will be required to secure a Stormwater
Construction General Permit from the Colorado Department of Public Health and Environment
(CDPHE), Water Quality Control Division – Stormwater Program, prior to any earth disturbance
activities. Prior to securing said permit, the Site Contractor shall develop a comprehensive
StormWater Management Plan (SWMP) pursuant to CDPHE requirements and guidelines. The
SWMP will further describe and document the ongoing activities, inspections, and maintenance of
construction BMPs.

Warning: The energy equation could not be balanced within the specified number of iterations.
The program used critical
depth for the water surface and continued on with the calculations.
Warning: The conveyance ratio (upstream conveyance divided by downstream conveyance) is less
than 0.7 or greater than
1.4. This may indicate the need for additional cross sections.
Warning: The energy loss was greater than 1.0 ft (0.3 m). between the current and previous cross
section. This may indicate
the need for additional cross sections.
Warning: During the standard step iterations, when the assumed water surface was set equal to
critical depth, the calculated
water surface came back below critical depth. This indicates that there is not a valid
subcritical answer. The
program defaulted to critical depth.

Warning: The energy equation could not be balanced within the specified number of iterations.
The program selected the
water surface that had the least amount of error between computed and assumed values.
Warning: The energy loss was greater than 1.0 ft (0.3 m). between the current and previous cross
section. This may indicate
the need for additional cross sections.
Note: Multiple critical depths were found at this location. The critical depth with the
lowest, valid, energy was used.

Warning: The energy equation could not be balanced within the specified number of iterations.
The program used critical
depth for the water surface and continued on with the calculations.
Warning: Divided flow computed for this cross-section.
Warning: During the standard step iterations, when the assumed water surface was set equal to
critical depth, the calculated
water surface came back below critical depth. This indicates that there is not a valid
subcritical answer. The
program defaulted to critical depth.
Note: Multiple critical depths were found at this location. The critical depth with the
lowest, valid, energy was used.

Warning: The energy equation could not be balanced within the specified number of iterations.
The program used critical
depth for the water surface and continued on with the calculations.
Warning: Divided flow computed for this cross-section.
Warning: During the standard step iterations, when the assumed water surface was set equal to
critical depth, the calculated
water surface came back below critical depth. This indicates that there is not a valid
subcritical answer. The
program defaulted to critical depth.

Warning: The energy equation could not be balanced within the specified number of iterations.
The program used critical
depth for the water surface and continued on with the calculations.
Warning: Divided flow computed for this cross-section.
Warning: The conveyance ratio (upstream conveyance divided by downstream conveyance) is less
than 0.7 or greater than
1.4. This may indicate the need for additional cross sections.
Warning: During the standard step iterations, when the assumed water surface was set equal to
critical depth, the calculated
water surface came back below critical depth. This indicates that there is not a valid
subcritical answer. The

Warning: The energy equation could not be balanced within the specified number of iterations.
The program used critical
depth for the water surface and continued on with the calculations.
Warning: Divided flow computed for this cross-section.
Warning: The conveyance ratio (upstream conveyance divided by downstream conveyance) is less
than 0.7 or greater than
1.4. This may indicate the need for additional cross sections.
Warning: The energy loss was greater than 1.0 ft (0.3 m). between the current and previous cross
section. This may indicate
the need for additional cross sections.
Warning: During the standard step iterations, when the assumed water surface was set equal to
critical depth, the calculated
water surface came back below critical depth. This indicates that there is not a valid
subcritical answer. The
program defaulted to critical depth.

Warning: The energy equation could not be balanced within the specified number of iterations.
The program used critical
depth for the water surface and continued on with the calculations.
Warning: The energy loss was greater than 1.0 ft (0.3 m). between the current and previous cross
section. This may indicate
the need for additional cross sections.
Warning: During the standard step iterations, when the assumed water surface was set equal to
critical depth, the calculated
water surface came back below critical depth. This indicates that there is not a valid
subcritical answer. The
program defaulted to critical depth.

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://www.nrcs.usda.gov/wps/
portal/nrcs/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/app?agency=nrcs) or your NRCS State Soil
Scientist (http://www.nrcs.usda.gov/wps/portal/nrcs/detail/soils/contactus/?
cid=nrcs142p2_053951).
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 (NRCS) 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 (MLRAs). MLRAs 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
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 the significant natural bodies of soil in the
survey area, they drew the boundaries of these bodies on aerial photographs and

identified each as a specific map unit. Aerial photographs show trees, buildings,
fields, roads, and rivers, all of which help in locating boundaries accurately.

Map Unit Descriptions
The map units delineated on the detailed soil maps 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 landforms 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,
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, 0 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.

This product is generated from the USDA-NRCS certified data as
of the version date(s) listed below.
Soil Survey Area: Larimer County Area, Colorado
Survey Area Data: Version 13, Sep 10, 2018
Soil map units are labeled (as space allows) for map scales
1:50,000 or larger.
Date(s) aerial images were photographed: Sep 20, 2015—Oct
21, 2017
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.
