"Information Only:This project is located within the City's MS4 boundaries and is subject to the erosion control requirements located in the Fort Collins Stormwater Criteria Manual (FCSCM), Chapter 2, Section 6.0. A copy of those requirements can be found at www.fcgov.com/erosion .
This project was evaluated based upon the submittal requirements of FCSCM.
Based upon the provided materials we were able to determine a total disturbed area.
The project is within 50 ft of a sensitive area.
Based upon the area of disturbance or this project is part of a larger common development, State permits for stormwater will be required should be pulled before Construction Activities begin.
For Approval or Final Plan:
Based upon the supplied materials, site disturbs more than 10,000 sq. ft. and/or meets one of the other
triggering criteria (sensitive area, steep slopes, or larger common development) that would require Erosion
and Sediment Control Materials to be submitted.
Please provide an erosion control plan for 'Final Plan or Approval Submittal'. This project disturbs 5 or more acres so erosion control phasing materials will need to be provided in the erosion control plans, reports and escrow. Please ensure that the Erosion Control Plans, Escrows, and Reports include phasing requirements (FCSCM Ch 2 Section 6.1.3, 6.1.4, & 6.1.5)
Based upon the supplied materials, site disturbs more than 1 acre or is part of a larger common development
that requires Erosion and Sediment Control Report to be submitted. Please submit an Erosion Control Report
to meet City Criteria (FCDCM Ch 2 Section 6.1.4) at time of Final Plan or Approval Submittal.
Based upon the supplied materials, an Erosion Control Escrow Calculation will need to be provided. Please submit an Erosion Control Escrow / Security Calculation based upon the accepted Erosion Control Plans to meet City Criteria (FCDCM Ch 2 Section 6.1.5) at time of Final Plan or Approval Submittal.
Fees:
The City Manager’s development review fee schedule under City Code 7.5-2 was updated to include fees for
Erosion Control and Stormwater Inspections. As of January 1st, 2021, these fees will be collected
on all projects for such inspections. The Erosion Control fees are based on; the number of lots, the total site disturbance, the estimated number of years the project will be active. Based on the proposed site construction associated with this project we are assuming 0 lots, 29.66 acres of disturbance, 4.5 years from demo through build out of construction and an additional 3.00 years till full vegetative stabilization due to seeding. Which results in an Erosion Control Fee estimate of $4,784.41 . Please note that as the plans and any subsequent review modifications of the above-mentioned values change the fees may need to be modified. I have provided a copy of the spreadsheet used to arrive at these
estimates for you to review. Please respond to this comment with any changes to
these assumed estimates and why, so that we may have a final fee estimate ready for this project. The fee
will need to be provided at the time of erosion control escrow.
The Stormwater Inspection Fees are based on the number of LID/WQ Features that are designed for on this project. Based on the plans we identified 0 number of porous pavers, 0 number of bioretention/level spreaders, 0 number of extended detention basins, and 3 number of underground treatments, results in an estimate of the Stormwater LID/WQ Inspection fee to be $ $1,245.00 . Please note that as the plans and any subsequent review modifications of the above-mentioned values change the fees may need to be
modified. I have provided a copy of the spreadsheet used to arrive at these estimates for you to review.
Please respond to this comment with any changes to these assumed estimates and why, so that we
may have a final fee estimate ready for this project. The fee will need to be provided at the time of erosion
control escrow. "

Topic: Erosion Control
Comment Number: 1 Comment Originated: 01/05/2022
03/21/2022: Waiting for FDP talks about Stockpiling lead me to believe that the erosion
control was going to be submitted. Erosion Control materials will need to be accepted
before stockpiling permits can be pulled. Will anticipate seeing that next round.
HKS Response: Stockpiling permit was submitted & processed through.
02/14/2022: Waiting for FDP for Erosion Control Materials.
01/05/2022:
09/09/2021:
02/24/2021: Information Only:
The site disturbs more than 10,000 sq. ft. and/or meets the criteria for a ne ed
for Erosion and Sediment Control Materials to be submitted. The erosion control
requirements are located in the Stormwater Design Criteria in Chapter 2 Section 6.0
a copy of the requirements can be found at www.fcgov.com/erosion
For Final:
Please submit an Erosion Control Plans to meet City Criteria.
HKS Response: Erosion Control Plans are included with this final submittal packet.
For Final:
Please submit an Erosion Control Escrow / Security Calculation based upon the
accepted Erosion Control Plans to meet City Criteria.
HKS Response: Erosion Control Escrow is included with this final submittal packet.
Information only:
Based upon the area of disturbance, State permits for stormwater will be required since
the site is over an acre and should be pulled before Construction Activities begin.
For Final:
Starting January 1st, 2020 fees will be changing, and the City will be collecting
fees for Erosion Control and Stormwater Inspections. The fees are based off; the number
of lots, the total site disturbance, the estimated number of years the project will be active
and the number of LID/WQ Features that are designed for on this project. Based upon
the materials submitted we are assuming 230 number of lots, 28 acres of disturbance,
Page 4 of 22
4.5 number of years from demo to complete the installation/construction and an additional
3 years till full vegetative stabilization.
We could not make any assumptions at this time for the LID and WQ, each porous pavers will
be $365.00, each bioretention $315.00, each extended detention basins $250.00, and each
underground treatment will be $415.00. Which roughly estimates an Erosion Control Fee of $10,932.84
and Stormwater LID/WQ Inspections to be $TBD . Please respond to this comment with any
changes to these estimates and why, so that we may have a final fee ready for this project.
The fee will need to be provided at the time of erosion control escrow.
DHI Response: Acknowledged.
HKS Response: Acknowledged.
Information Only:
Please take added precautions near the Waters of the US (Ditch adjacent) and
please plan accordingly to high ground water where Concrete washouts may
need liners and dewatering permits should be looked into for any major subgrade work.

01/26/2022: FOR FINAL:
Thank you for making the recent grading updates to Pond 1. For Final Plan,
please continue to increase the landscaping aesthetic of this pond.
Ripley Response: Landscape design has been updated around the ponds. The intent for the planting plan is help break up the
planting into informal groupings and help accentuate the naturalized slopes.
01/11/2022: FOR HEARING - UPDATED: (addressed)
Pond 1 does not meet the City’s requirements for pond landscaping and
aesthetics. To meet this requirement, we suggest the following:
- Break up the retaining wall at ~100-ft increments.
- The retaining wall should not be located in the Utility Easement.
- Round off the pond corners
- Use boulders as architectural features.
- The long uniform slope on the north side will need some variation.

Enclave at Redwood
Page 3 of 9
October 19, 2022
I. Location
The proposed Enclave at Redwood development (hereinafter referred to as “Site”) is located in the
southeast ¼ of Section 1, Township 7 north, Range 69 west of the sixth Principal Meridian, City of
Fort Collins, County of Larimer, State of Colorado. The Site is bounded by Redwood Street to the west
and East Suniga Road to the south. A small portion of the Site exists south of East Suniga Road.
Adjacent developments include the Meadows at Redwood PUD Phase 1 (Redwood Meadows) to the
west, Northfield to the east and southeast, and Evergreen Park 3rd (Evergreen) to the north. Lake
Canal exists as an irrigation ditch adjacent to the Site to the east and southeast, and Redwood
Channel lies adjacent to the Site to the north. The Site will connect to Redwood St to the southwest,
Lupine Dr in Redwood Meadows to the west, Steeley Dr in Northfield to the southeast, and Collamer
Dr in Northfield to the east.
The Site consists of approximately 29.66 acres of undeveloped land, more specifically, totally
undeveloped grassland.
The Vicinity Map is included in Appendix A for reference.
II. Nature of Construction Activity
The Site will be developed as multi-family residential housing, with a mix of 1-, 2- and 3-bedroom
units totaling 238 units among 40 1- and 2-story buildings. The proposed development will also
include a clubhouse with a pool, amenity courtyard; surface parking, public and private roads, and
the associated utilities.
III. Sequence of Major Activities
The proposed sequence for major activities is described in detail in the Stormwater Management
Considerations section below. Please note that stockpiling activities have been designed as a
separate document due to a significant amount of fill that will be needed for the site.
IV. Estimates of Site Area
The Site is approximately 29.66 acres. Areas that will be disturbed by demolition, excavation, grading,
utility installation and other construction activities include approximately 26.31 acres of on-Site work
and 4.36 acres of off-site for a total of 30.67 acres. The exact limits of disturbance are shown on the
SWMP included in Appendix D.
V. Summary of Existing Data
Currently, the Site is comprised of undeveloped grassland covering approximately 98% of the Site
based on observation. There are no visible existing structures or foundations. There is an existing City
owned drainage swale along the northern portion of the site. This ditch conveys water from the
redwood meadows pond that is northwest of the site and flows from west to east to the wetlands
area northeast of the site. There is also an existing irrigation canal owned by the Lake Canal Reservoir
Company adjacent to the Site to the east and southeast, which flows from southwest to northeast.
Stormwater Management Plan
Enclave at Redwood
Page 4 of 9
October 19, 2022
The Site generally slopes from west to east at grades between roughly 0.3% and 1% towards Lake
Canal. The side slopes of the canal vary from 2:1 to 4:1. The thalweg slope of the canal is very flat.
During irrigation flows in the canal, the canal flows to the northeast along the east property
boundary. Perimeter silt fence will contain stormwater run-off onsite. There are currently no existing
stormwater or erosion control measures on-site.
The Redwood Meadows Pond has existing wetlands area which is adjacent to the northwest corner
of the site. The wetlands boundary is approximately 10’ feet away from the property line. The
wetlands area is approximately 0.53 acres. There is an additional pond to the northeast. This pond is
the Evergreen East Pond which has approximately 1.64 acres of wetland. The city owned ditch on the
north side of the site connects these two wetland areas. Perimeter controls will be implemented
along the south edge of the city owned ditch to retain stormwater onsite. Impacts to the wetlands
are not anticipated at this time and erosion measures will be put in place to contain stockpiles and
protect the Redwood Meadows Pond and wetlands from any site runoff.
There are three soil types as identified by the Natural Resource Conservation Service (NRCS) Web
Soil Survey. Loveland Clay Loam, Nunn Clay Loam, and Nunn Clay Loam (wet). All soil on site is
classified as hydrologic soil group C. These soils are cohesive and are moderately resistant to wind
and water erosion. A copy of the soil survey is included in Appendix B.
Ground water was also encountered during initial soil testing. Groundwater depths range from 8-12
feet from existing grade and will eventually be 8-17 feet under finished proposed grades.
Groundwater was not sampled and tested for any existing contamination. Soil testing did not show
any ground contamination.
The Site is shown on the Federal Emergency Agency’s (FEMA) Flood Insurance Rate Map (FIRM)
Community Panel Numbers 08069C0977G and 08069C0981G, effective June 17, 2008. Lake Canal is
partially located within Zone X (0.2% annual chance flood hazard) and therefore the Site is partially
within this zone. Because the development of the Site will not involve altering of Lake Canal, no
floodplain modifications are necessary. Please refer to Appendix A for more details.
VI. Existing Vegetation
Currently, the Site consists of mostly native grasses and vegetation. Vegetation covers approximately
98% of the site. There is very little impervious area onsite, if any, in the current condition.
VII. Potential Pollution Sources
The construction activities associated with this project will have some potential to pollute the
storm water being discharged from the Site. If these erosion measures are not properly installed
off-site sediment may occur with large stormwater flows. This has potential to damage the
surrounding wetlands. Below are the pollutants with a short description of each:
Stormwater Management Plan
Enclave at Redwood
Page 5 of 9
October 19, 2022
Disturbed and Stored Soils
Disturbed and stored soils are a potential pollution source for the Site. Implementing dust
mitigation, rock socks, and silt fence will control the disturbed and stored soils. Due to the large
amount of Import for this site, a separate stockpile SWMP has been done. And all soil will be onsite
before commencement of other construction activities. Because of this temporary sediment control
measure such as silt fence, and rock socks will already be in place, and will remain until necessary
to remove.
Vehicle Tracking of Sediments
Vehicle tracking of sediments is a potential pollution source for the Site and will be controlled by a
vehicle tracking control pad(s) located at the construction entrance(s). Fencing will also limit vehicle
access to designated entry(s). Street sweeping will also be utilized to limit the tracking of sediment
off-site.
Management of Contaminated Soils
The Contractor is responsible for monitoring for contaminated soils and notify the engineer and
Larimer County if discovered. Stock piling activities will only grub topsoil. Material exposure is not
anticipated to be encountered at this time. On-site soil samples did not contain any contamination.
It is the contractor’s responsibility to collect and legally dispose of contaminated soils.
Loading and Unloading Operations
Loading and unloading operations is a potential pollution source for the Site. Loading and
unloading operations shall take place within the stabilized staging area.
Vehicle and Equipment Maintenance and Fueling
Vehicle and equipment maintenance and fueling is a potential pollution source for the Site.
Measures shall also be taken to prevent spills or leaks of fuel, oils, lubricants, antifreeze, and other
contaminant fluids from construction vehicles to protect groundwater and stormwater runoff. All
equipment maintenance shall be performed in a designated area, and measures such as drip pans
shall be used to contain petroleum products. Spills of construction materials should be cleaned up
immediately and disposed of properly. The Contractor shall routinely inspect equipment for leaks
that could lead to discharge of petroleum products into surface runoff.
Outdoor Storage Activities
Outdoor storage activities are a potential pollution source for the Site. Materials sometimes used
at a construction site present a potential for contamination of stormwater runoff. These may
include, but are not limited to building materials, fuel, oil, lubricants, paints, solvents, concrete
curing compounds, pesticides, fertilizers, chemicals, herbicides, etc. The contractor shall designate
an area where these products are stored in an enclosure, container, or lined earthen dike,
constructed to prevent discharge of these materials in runoff from the Site. These barriers will also
function to contain spilled materials from contact with surface runoff. Standard Operating
Procedures for material spill containment and clean-up are provided in Appendix C. Material other
than soil is not anticipated to be stored during stock piling activities.
Stormwater Management Plan
Enclave at Redwood
Page 6 of 9
October 19, 2022
Dust or Particulate Generating Processes
Significant dust or particulate generating processes are a potential pollution source for the Site.
Dust mitigation, surface roughening, and seeding and mulching shall be implemented to mitigate
airborne dust pollutants. These activities will be need to be conducted in accordance with the City
of Fort Collins Fugitive Dust Ordinances. The Dust Control Manual can be found at
www.fcgov.com/dust
On-Site Waste Management Practices
On-site waste management practices (waste piles, liquid wastes, dumpsters, etc.) are not a
potential pollution source for the Site during stockpile activities.
Concrete Truck/Equipment Washing
Concrete truck and equipment washing is not a potential pollution source for the Site and should
only occur at the designated Concrete Washout Area shown on the SWMP.
Dedicated Asphalt and Concrete Batch Plans
Dedicated asphalt and concrete batch plants are not a potential pollution source for the Site. There
will not be any dedicated concrete or asphalt batch plants on site.
Non-Industrial Waste Sources
Non-industrial waste sources such as worker trash and portable toilets are not potential pollution
source for the Site.
Other Areas or Procedures Where Potential Spills Can Occur
Other areas or procedures where potential spills can occur are not a potential pollution source for
the Site.
VIII. Potential Non-Stormwater Discharges
Non-stormwater components of discharge, such as condensate from construction trailers,
underground springs and landscape irrigation return flow are not anticipated to occur with this
development. However, the contractor shall be responsible to monitor for such discharges and notify
the engineer in such an event. If construction dewatering is necessary, the contractor shall be
responsible for ensuring a construction dewatering permit is obtained prior to discharging water to
surface water or storm sewer systems.
IX. Receiving Water(s)
During high stormwater events, the Site currently drains to the lake canal ditch, city owned ditch and
some minor flow may make its way into the redwood meadows pond. There are no controls on site
to direct run off in any concentrated direction. According to the EPA, there are two receiving waters
for this Site; Dry Creek which is the receiving water for the North East College Corridor Outfall
(NECCO) and Timnath Reservoir which receives irrigation water from Lake Canal Reservoir Company.

X. Construction Schedule
Construction activities on this Project is scheduled to commence fall of 2023 with anticipated
completion will be in the fall of 2024. Construction BMP’s for the entire Site shall be installed
according to the SWMP in Appendix E.

XII. Erosion and Sediment Control Measures (BMP’s)
The following Best Management Practices (BMPs) shall be implemented as indicated, prior to and
during construction activities on the site. The information shown below describes the BMP, when it
is estimated to be installed, and the maintenance requirements of the BMP. The Plan Set in
Appendix D displays the locations of the BMPs. The associated City of Fort Collins details can be
seen in Appendix D for BMP installation and maintenance.
Silt Fence (SF)
Stormwater Management Plan
Enclave at Redwood
Page 8 of 9
October 19, 2022
A woven geotextile fabric attached to wooden posts and trenched into the ground. It is used to
intercept sheet flow runoff from disturbed areas. The silt fence shall be installed prior to all land
disturbing activities. The contractor shall inspect and maintain all silt fence throughout
construction. Any section of silt fence that has a tear, hole, slumping, undercutting or has been
bypassed should be replaced with a new section. Accumulated sediment should be removed before
it reached a depth of 50% the height of the silt fence.
Vehicle Control Tracking (VTC)
A stabilized construction site access where vehicles exit the site onto paved public roads. It helps
removed sediment from vehicles, reducing tacking onto the paved surface. The vehicle control
tracking shall be installed prior to any land disturbing activities. Vehicle tracking control shall be
inspected and maintained throughout construction. Replace aggregate or material used for
stabilization at entrance/exit as needed. Ensure drainage ways are not blocked by vehicle tracking
control.
Stockpile Management (SP)
Area on site where soils and other erodible materials are stored. Includes measures to minimize
erosion and sediment transport from soil stockpiles. The stockpile management area shall be
installed prior to any land disturbing activities. Stockpiles shall be inspected and maintained
throughout construction activities.
Inlet Protection (IP)
Permeable barriers installed around an inlet to filter runoff and remove sediment prior to entering
a storm drain inlet. These can be constructed from rock socks, sediment control logs, silt fence,
block and rock socks, or other materials approved by Commerce City. Area inlets can also be
protected by over-excavating around the inlet to form a sediment trap. Inlet protection shall be
installed prior to any land disturbing activities. Inlet protection shall be inspected and maintained
throughout construction activities. Ensure that flows do not bypass the inlet protection when
flowing to the storm drainage system. Accumulated sediment should be removed before it reaches
a depth of 50% the height of the inlet protection.
Rock Sock (RS)
Gravel that has been wrapped by wire mesh or a geotextile to form an elongated cylindrical filter.
Used either as a perimeter control or as part of inlet protection. These are intended to trap
sediment from storm water runoff that flows onto roadways because of construction activities.
Rock socks shall be installed prior to any land disturbing activities. Rock socks shall be inspected and
maintained throughout construction activities. Accumulated sediment should be removed before it
reaches a depth of 50% the height of the rock sock.
Construction Fence (CF)
Fence that restricts site access to designated entrances and exits, delineates construction site
boundaries and keeps construction out of sensitive areas such as natural areas to be preserved as
open space, wetlands and riparian areas. These may be chain link or plastic mesh. Construction
fence shall be installed prior to any construction activities. Construction fencing shall be inspected
and maintained through construction activities.
Stormwater Management Plan

October 19, 2022
Seeding and Mulching (SM)
Measures that include means to return the exposed dirt to a stabilized condition, one what will not
continue to result in erosion or sediment transport. A City approved seed mix will be applied to
stabilize the stock pile until final grading activities have commenced.
Street Sweeping (SS)
Street sweeping and vacuuming is to remove sediment that has been tracked onto roadways to
reduce sediment transport into storm drain systems or a surface waterway. This can be done
manually or with specific vehicles designed for this purpose. Street sweeping should be performed
in periodic intervals and when there is noticeable sediment accumulation.
XIII. SWMP Administrator
The stormwater management plan (SWMP) administrator shall be the Construction Site
Superintendent.
The Site superintendent is responsible for implementing and maintaining the Stormwater
Management Plan.
The SWMP administrator shall contact the engineer of record for development and revisions of
the SWMP.
The SWMP administrator shall be responsible for reporting spills.
The SWMP administrator shall conduct Site inspections and shall verify that repairs to the BMPs
have been completed and certify corrections.
The SWMP administrator shall conduct BMP training.
XIV. Final Stabilization and Long-Term Stormwater Management
Upon the completion of stockpiling activities, proper stabilization and vegetation will be established
with a native seed mix. Disturbed open space areas and the stock pile area will be planted with Native
Seed. Disturbances are to be minimized, especially on slopes greater than 4:1. Final stabilization is
reached when all soil-disturbing activities at the Site have been completed, and uniform vegetative
cover has been established with a density of at least seventy percent of pre-disturbance levels or
equivalent permanent, physical erosion reduction methods have been empl oyed. Soil compaction
will be minimized for areas where final stabilization will be achieved through vegetative cover or an
infiltration control measure.
Seeding needs to comply with City of Fort Collins landscape standards. See Stockpile plan notes to
establish proper native seed application and acceptance. All seeded areas will be crimped and
mulched same day or next day after seeding in accordance with the Temporary and Permanent
Seeding Details associated with this project as seen in the appendix, and in accordance with the City
of Fort Collins Erosion Control Criteria. Once installed there will be no temporary irrigation system so
all seeding will be monitored until the site has reached a vegetative cover (density) of 70%. It is
anticipated that this site will be seeded in the spring of 2023 and will be fully established in the fall
of 2026. At the point the vegetation has reached 70% density, and confirmed by the City of Fort
Collins, the warranty period for Erosion Control will begin, all stormwater infrastructure will be
cleaned and removed of any sediment deposits and any remaining temporary Control Measures will
be removed.

XV. Inspection and Maintenance
At a minimum, the Permittee or contractor shall produce and retain weekly written inspection
records for all BMP’s and after significant precipitation events. All necessary maintenance and
repair shall be completed immediately. However, street sweeping is to be completed by the close
of the business day or on an as needed basis. It is the responsibility of the contractor to have all
erosion control devices in place and effective, prior to a storm event. Permittee or Contractor shall
produce written inspection records every seven (7) days and after significant precipitation events.
The SWMP Administrator must maintain a record of inspection results for a period of three (3)
years following expiration or inactivation of permit coverage.
Record Keeping and Documenting Inspections
The following items, at a minimum, must be documented as a part of the Site inspections:
i. The inspection date;
ii. Name(s) and Title(s) of personnel making the inspection;
iii. Weather conditions at the time of inspection;
iv. Phase of construction at the time of inspection;
v. Estimated acreage of disturbance at the time of inspection;
vi. Location(s) of discharges of sediment or other pollutants from the Site;
vii. Location(s) of control measures requiring routine maintenance;
viii. Location(s) and identification of inadequate control measures requiring corrective actions;
ix. Location(s) and identification of additional control measures need that were not in place at the
time of inspection;
x. Description of the minimum inspection frequency and any deviations from the minimum
inspection schedule
After adequate corrective action(s) has been taken, or where a report does not identify any incidents
requiring corrective action or maintenance, the report shall contain a signed statement indicating
the Site is in compliance with the permit to the best of the signer’s knowledge and belief.
XVI. Conclusion
This Stormwater Management Plan is in conformance with the State of Colorado Stormwater
Management Plan Preparation Guidance. Additional grading, erosion and sediment control
measures may be required of the owner or his/her agents, due to unforeseen erosion problems or
if the submitted plan does not function as intended. The requirements of this plan shall be the
obligation of the landowner and/or his successors or heirs; until such time as the plan is properly
completed, modified, or voided.

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.
Custom Soil Resource Report

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,
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.
