I. Introduction
General Location
The proposed Bloom subdivision is located directly south of East Vine Drive and north of East Mulberry
Street, just west of I-25, to the east of the Mosaic Subdivision in Fort Collins, Colorado. The overall Bloom
development is bordered to the north by East Vine Drive; to the east by the Imu-Tek Animal Health Clinic
and undeveloped land; to the south by East Mulberry Street; and to the west by East Ridge Second
Filing, also referred to as the Mosaic Subdivision. The project site is located in the Northwest Quarter of
Section 9, Township 7 N., Range 66 W. of the 6th P.M., City of Fort Collins, County of Larimer, State of
Colorado. A vicinity map is included in Appendix A for reference.
Existing Site Info
The project site consists of approximately 260 acres of vacant and undeveloped tract of land that is
currently being used for farming. Existing grades across the site vary from 0.5 to 3 percent. The site
generally drains from north to south. There are existing train tracks across the northern portion of the site
that run diagonal from the northwest to the southeast. The project site is located within the Cooper
Slough/Boxelder Basin and the Cooper Slough channel is located just to the east of the project site. The
Lake Canal also cuts across the southwest corner of the site.
According to the Natural Resources Conservation (NRCS) Web Soil Survey, the project site consists of a
mix of soil types and Hydrologic Soil Groups (HSG) including:
- Ascalon Sandy Loam (33%), HSG ‘B’
- Fort Collins Loam (27%), HSG ‘C’
- Garrett Loam (23%), HSG ‘B’
And smaller percentages of various other soil types as shown on the soil map included in Appendix A.

II. Master Drainage Basin
Overall Basin Description
The project site is located in the lower portion of the Cooper Slough Watershed. The master plan for this
drainage basin is currently being updated but we were able to review a copy of the plan dated February
2021. This report is titled “City of Fort Collins Upper Cooper Slough Basin Selected Plan of
Improvements” prepared by Icon Engineering, Inc. (Master Plan). The Cooper Slough drainage basin
resides in northeast Fort Collins and unincorporated Larimer County, Colorado. The Master Plan
describes it as a long and slender watershed, flowing from north to south, comprising 28 square miles
which are tributary to Box Elder Creek and the Cache la Poudre River. The watershed begins at the
confluence with Box Elder Creek (about one-half mile south of Mulberry Street and slightly west of I-25)
and proceeds north for 20-miles to Larimer County Road 80 at a location northwest of the Town of
Wellington. The basin has a maximum width of 3.9-miles at a location just south of Wellington.
Predominant land uses are characterized by farmland and open space, with development occurring
mainly in the southern portion of the watershed, near northeast Fort Collins.
The Cooper Slough watershed has been divided into upper and lower portions by the Larimer & Weld
Canal. The project site is located in the lower portion of the watershed.
The Master Plan discusses improvements to the Cooper Slough and Lake Canals including culverts
installed in Vine and Mulberry, but these improvements lie outside of the boundaries of this project and
therefore are not a part of this project. There will be no changes to the Cooper Slough or Lake Canals as
part of this project.
The proposed development to the southeast of the project site, Peakview, has included a portion of a box
culvert that will eventually divert water from the Lake Canal to the Cooper Slough. The box culvert will be
designed, constructed, plugged, and buried until future master plan culvert improvements are
constructed.
Relevant excerpts from the Master Plan have been included in Appendix B.
Existing Drainage Facilities
A historic/existing basin map was developed with this drainage report, reference Appendix D, in order to
calculate the historic runoff from the site. A SWMM model was used to determine the existing runoff and
the 2-year and 100-year runoff values from the models are included in the basin descriptions below.
According to the Master Plan, future development with the area of the site is to “Limit the release (both
Bloom Filing 1

Galloway & Company, Inc.Page 5 of 28
peak discharge and volume) associated with future development within the Upper Cooper Slough Basin
to the 100-year existing condition release rates into the lower Cooper Slough area.”
Basin H-1 (±72 acres, Q2 = 4.0 cfs, Q100 = 26.0 cfs) is associated with the northeastern portion of the
site to the north of the Burlington Northern Railroad tracks. Runoff generally runs south toward the
railroad tracks and then is conveyed east into the Cooper Slough.
Basin H-2 (±22 acres, Q2 = 1.3 cfs, Q100 = 15.5 cfs) is associated with the northeastern portion of the
site on the south side of the Burlington Northern Railroad tracks. Runoff generally runs south into
undeveloped land.
Basin H-3 (±162 acres, Q2 = 8.7 cfs, Q100 = 52.0 cfs) is associated with the western portion of the site.
Runoff currently sheet flows south into the Lake Canal.
Basin H-4 (±6.5 acres, Q2 = 0.4 cfs, Q100 = 8.7 cfs) is associated with the southwest portion of the site.
Runoff currently sheet flows east into the adjacent property and then to the Lake Canal.
Floodplain
The Cooper Slough runs along the eastern boundary of the Bloom Filing 1 Development. According to
the Federal Emergency Management Agency (FEMA) Flood Insurance Rate Map Panels 982 (FIRM
Number 08069C0982F) effective date December 19, 2006 and Panel 984 (FIRM Number 08069C0984H)
effective date May 2, 2012 included in Appendix A, a portion of the site lies within Zone AE of the Cooper
Slough, an area subject to inundation by the 1% annual chance (1-PAC) flood (I.E. the 1-PAC floodplain).
In Zone AE, the base flood elevations (BFEs) have been determined.
However, a LOMR (FEMA Case No.: 17-08-1354P) became effective February 21, 2019, removing BFEs
from the area and replacing them with 1-PAC water surface elevations at cross sections. The LOMR was
submitted as a part of a restudy of the Boxelder and Cooper Slough prepared for the Boxelder
Stormwater Authority by Ayres Associates. A Preliminary FIRM Panel, 08069C0984J dated January 26,
2021 included in Appendix A, presents the effective 1-PAC floodplain delineation, floodway delineation,
and 1-PAC water surface elevations from the 2019 LOMR. The effective 1-PAC floodplain encroaches on
planned Pond B and part of Pond C, as well as in a significant portion of the Bloom Development’s
southern end south of the planned Donella Drive. No development activities are planned to encroach on
the effective floodway. All elevations provided are in reference to the NAVD 1988, with Cooper Slough
effective 1-PAC floodplain water surface elevations ranging between 4930.5 ft and 4960.2 ft adjacent to
the Bloom Filing 1 Development.
Bloom Filing 1
Final Drainage Report
Galloway & Company, Inc.Page 6 of 28
The development shall follow floodplain regulations stated in Chapter 10 of the City Code. All structures
shall have the elevation of the lowest floor be above regulatory flood protection elevations. It is
anticipated that no work shall commence within the floodway.
This drainage report is prepared as an addendum to the floodplain use permit application that is
submitted to the City of Fort Collins, allowing for the site to be built upon approval. A separate LOMR will
be prepared that will analyze the impact of the as-built development on the effective 1-PAC floodplain and
associated water surface elevations. The LOMR will be completed and approved before issuance of any
certificate of occupancy (CO).
III. Project Description
The entire Bloom development encompasses approximately 260 acres and will include the development
of both single and multi-family homes, commercial use, and associated streets, utilities, and open space.
The project site is bordered to the west by East Ridge Second Filing, also referred to as the Mosaic
Subdivision, which is a single and multi-family development; to the north by the Trail Head Subdivision,
another single-family development; to the southeast by the proposed Peakview development; and to the
south (south of Bloom) and southwest by various commercial developments.
This report summarizes the drainage facilities for Filing 1 including any channel improvements, limited
impact development best management practices and proposed water quality/detention.
Existing Conditions
Filing 1 is 66.8 acres of vacant undeveloped farming land. Existing grades of the Site generally slope from
0.5 to 3 percent.
Proposed Conditions
Filing 1 of Bloom encompasses ±66.8 acres in the northwest area of the overall development. It will
include the development of 130 single family homes, 138 town homes, associated streets, utilities, and
open space. The area of Filing 1 drains from north to south to two detention/irrigation ponds at grades of
0.5 to 4.0 percent. These two onsite ponds will outfall into another offsite pond downstream where it will
eventually outfall into the Cooper Slough. Filing 1 will also include the storm infrastructure for Greenfields
Drive and main trunk lines for the future development along with their associated ponds.

IV. Proposed Drainage Facilities
General Concept
Runoff from the developed site will be conveyed via overland flow, bioretention, and curb and gutter to a
proposed storm drain system that will convey the major and minor event stormwater runoff to onsite
detention ponds. There will be (2) two ponds in Filing 1 that will provide detention and water quality for the
Site and one (1) detention pond directly east that will control release into the Cooper Slough. Pond D will
outfall into the pond off site which outfall directly into the Cooper Slough. Releases from Pond E will travel
south eventually outfalling into the Lake Canal Overflow Channel.
The ODP has divided the project site into eight large basins, one for each detention pond. Filing 1
analyzes developed Basin D and Basin E. The runoff from the basins and the sizing and release rates for
the proposed ponds have been calculated using 0.2 cfs/acre criteria. A variance is to be provided to allow
for this change instead of using the historic 2-year flow (FCSCM Criteria) as the release rate or using the
Master Drainage Plan’s 100 year historic release.
Pond D will release flows into Pond C. Pond C’s release rate will be controlled to be less than the
allowable release that was calculated. Pond C will release at or less than 25.8 cfs combined into the
Cooper Slough. Pond C will release at 21.6 cfs, less than allowable. The release rates were analyzed
using EPA SWMM 5.1. A summary of the pond volumes and release rates from the SWMM model is
included in Appendix C. Water rights are to be provided for the ponds that are storing permanent irrigation
pools (Pond D and Pond E) per State of Colorado.
Additional future ponds Pond A, Pond B, Pond G and Pond H, have been sized for their anticipated
tributary land use. These ponds are to be provide 100 Year detention and release at the site’s allowable
rate. Due to the releasing less than allowable on the upstream side, Pond C, more flow is being released
for the downstream release rate. Chart provided in Detention Pond section of this report. Water Quality
plate may be revised once the future use has been finalized with that specific filing.
Water Quality will be provided onsite through Low Impact Development (LID) practices and also within the
detention ponds. City of Fort Collins requires at least 50% of newly added impervious areas are treated
with LID’s practices.
There are no offsite basins that impact the project site.
There are no proposed improvements to the Cooper Slough associated with the development of Filing 1.
A floodplain permit is to be submitted prior to any work being done within the floodplain.

Proposed Drainage Basins
Basin D
Basin D comprises of approximately 35.6 acres. This area includes single family detached and town
homes. The developed runoff within these basins will drain into separate LID features throughout the site
until eventually outfalling into the water quality detention pond. These LID features will provide the water
quality for the minor storm events and any storm event greater will be conveyed into the proposed storm
system via overflow structures.
Basin E
Basin E comprises of approximately 33.7 acres. This area includes town homes and future multi-family
development. The developed runoff within these basins will drain into separate LID features throughout
the site until eventually outfalling into the water quality detention pond. The future multi-family area which
includes sub basin, E14.1, E15.1, E19, and E26, E26.1, will need to follow LID criteria. In particular, no
less than 50% of any newly added impervious area must be treated using one or a combination of LID
techniques, and no less than 25% of any newly added pavement areas must be treated using a
permeable pavement technology.
Basin G
Basin G comprises of approximately 40.3 acres. This area includes future developed residential property
and the interior roadways of the development. This basin also includes the development of Greenfields
Drive. All of Basin G is tributary to Pond G and will be treated for water quality and store the 100-year
storm.
Basin H
Basin H comprises of approximately 16.7 acres. This area includes future developed residential property
and the interior roadways of the development. This basin also includes the development of Greenfields
Drive. All of Basin H is tributary to Pond H and will be treated for water quality and store the 100-year
storm.

Detention Pond
Each pond will provide both water quality and detention. It was determined that a more appropriate
historic release rate calculation would be the 0.2 cfs / acre instead of the 2-year historic. For the 160.3
acre development releasing into the northern part of the Cooper Slough, this yields an allowable release
of 32.06 cfs. The Site’s tributary detention ponds are modeled with a 100 year volume of 4.6 ac-ft for
Pond C, 6.6 ac-ft for Pond D, and 5.1 ac-ft for Pond E. SWMM was used to route flows from each pond to
determine the sizing and release rates from each pond. The final design for the water quality detention
pond has a 40-hr drain time to allow for stormwater treatment to occur. Each pond shall completely drain
for any event that is greater than the 5-year storm within 120 hours. The flows from Pond D’s outlet
structures will connect to a future offsite pond (Pond C) and eventually outfall to the Cooper Slough.
Ponds A, B, C, G and H have been designed in its final state and will provide water quality. In future
filings, the water quality plate will be resized for the actual imperviousness that is tributary to those ponds.
The table below shows release rates and volumes.
Sizing of spillway, water quality orifice plates, water surface elevations, etc. has all been included in
Appendix D of this report.

Water Quality
The ODP has determined that water quality and detention will be required for the development of the Site.
Required “Water Quality Capture Volume (“WQCV”) was calculated using equation 7-1 and Equation 7-2
from FCSCM.
Basin D will require 0.317 ac-ft for WQCV and Basin E will require 0.442 ac-ft respectively. The final
design for the water quality detention pond has a 40-hr drain time to allow for stormwater treatment to
occur. Flow from the outlet structure of Detention Pond D connects to a future offsite pond and eventually
outfall to the Cooper Slough. Pond E will flow south and eventually outfall into the Peakview storm
infrastructure.
LID
Permanent BMP’s are being considered in helping to allow for runoff reduction throughout the site. The
usage of bioretention is the primary BMP to be placed in landscaping areas to provide both infiltration and
filtration for the minor storm events. All LID’s will act as bioretention. For LID 1 & 2 a sand filter will be
used. This will require additional scheduled maintenance which can be found in the SWMP report with
this submittal. All other LID’s will be bioretention. The implementation of permanent BMP’s throughout the
site has met the treatment at least 50% of added impervious area, refer to Appendix D.

V. Drainage Design Criteria
Directly Connected Impervious Area (DCIA)
At this final stage of the design process, we’ve developed a strategy for implementing ‘The Four-Step
Process’ for stormwater quality management. Each step is listed below and includes a brief narrative
describing the implementation strategy.
Step 1 -Employ runoff reduction practices
Developed runoff from the D & E series of basins will drain through multiple bio-retention facilities prior
to entering the on-site detention facilities. The proposed bio-retention facilities are to provide enough
depth to capture WQCV of their respective basins. They are designed to allow infiltration of the 2-year
storm event and will provide bypass in larger storm events. The design encourages settling of
sediments, filtering, and infiltration. The MHFD defines bio-retention is an
“engineered, depressed landscape area designed to capture and filter or infiltrate the water quality
capture volume (WQCV).”
Basin’s E19 and E26 consists of Future Multi-Family development and Basin E14.1, E15.1, and E26
and E26.1 will need to provide its own on-site LID at the time of its development and submittal process.
The following table is the anticipated amount of the newly added impervious area and a breakdown of
the total area treated by an EDB or an LID feature.

Galloway & Company, Inc.Page 12 of 28
Step 2 -Implement BMPs that provide a Water Quality Capture Volume (WQCV)
The developed runoff from the D and E basins will drain into an Extended Detention Basin (EDB). The
MHFD defines an Extended Detention Basin as “An engineered basin with an outlet structure designed
to slowly release urban runoff over an extended time period to provide water quality benefits and control
peak flows for frequently occurring storm events. The basins are sometimes called "dry ponds" because
they are designed not to have a significant permanent pool of water remaining between storm runoff
events. Outlet structures for extended detention basins are sized to control more frequently occurring
storm events.” Note, these ponds are also to be irrigation ponds and shall have standing water.
Step 3 -Stabilize drainageways
Measures will be implemented to protect the Cooper Slough from the on-site detention pond outflows.
Step 4 -Implement site specific and other source control BMPS
Site specific considerations such as material storage and other site operations are addressed in the
Stormwater Management Plan (SWMP).
The City Rainfall Intensity-Duration-Frequency Curves as depicted in the FCSCM are utilized as the
source for all hydrologic computations associated with the development of the Site.
The Rational Method has been utilized to calculate stormwater runoff for the proposed condition sub-
basins within the Site. The coefficients tables along with frequency adjustment factors from FCSCM have
been utilized in support of these calculations.
Development Criteria Reference and Constraints
The project must release at historic rates for each drainage basin, however due to the site being located
on flat, farmland it has been determined that 0.2 cfs/acre would be a more appropriate release into the
Cooper Slough. The 2 year historic release rate from the proposed basin delineation which includes Basin
A, B, C, D, and E is 9.69 cfs. Instead of using the calculated 2 year historic, 0.2 cfs/acre is the methodology
in determining maximum allowable release rate. This was calculated to be 25.8 cfs for the northern portion
of the site and 44.4 cfs for total site. Pond D (Filing 1) and Future Pond A and Future Pond B will connect
into Pond C which will release at a controlled rate of 21.6 cfs. Pond E (Filing 1) will flow south into the
Peakview storm infrastructure that flows into the Cooper Slough at a rate of 20.8 cfs.
Bloom Filing 1
Final Drainage Report
Galloway & Company, Inc.Page 13 of 28
Hydrological Criteria
For urban catchments that are not complex and are generally 160 acres or less in size, it is acceptable that
the design storm runoff be analyzed using the Rational Method. The Rational Method is often used when
only the peak flow rate or total volume of runoff is needed (e.g., storm sewer sizing or simple detention
basin sizing). The Rational Method was used to estimate the peak flow at each design point. For preliminary
design, no routing (i.e., time attenuation) calculations were completed; this work will occur at Final Design.
When a total flow is reported within this preliminary drainage report, assume it is simply a summation of all
upstream flows.
The Rational Method is based on the Rational Formula:
Q = CiA
Where:
Q = the maximum rate of runoff, cfs
C = a runoff coefficient that is the ratio between the runoff volume from an area and the average
rate of rainfall depth over a given duration for that area
i = average intensity of rainfall in inches per hour for a duration equal to the Time of Concentration
(Tc)
A = area, acres
The one-hour rainfall Intensity-Duration-Frequency tables for use with the Rational Method of runoff
analysis are provided in Table 3.4-1 and Figure 3.4-1 (refer to Appendix B).
The 2-year and 100-year storm events are the basis for the preliminary drainage system design. The 2-
year storm is considered the minor storm event. It has a fifty percent probability of exceedance during any
given year. The 100-year storm is considered the major storm event. It has a one percent probability of
exceedance during any given year.
The 2-year drainage system, at a minimum, must be designed to transport runoff from the 2-year recurrence
interval storm event with minimal disruption to the urban environment. The 100-year drainage system, as a
minimum, must be designed to convey runoff from the 100-year recurrence interval flood to minimize life
hazards and health, damage to structures, and interruption to traffic and services.
The final detention storage was estimated with EPA SWMM 5.1. Various input parameters were provided
by Table 4.1-1 and Table 4.1.4. The total detention discharge of the site is 44.1 cfs.
Bloom Filing 1
Final Drainage Report
Galloway & Company, Inc.Page 14 of 28
Hydraulic Criteria
The on-site excess developed runoff within each tributary area begins as overland flow from residential lot
areas to stormwater quality features. Runoff then flows from lots to the adjoining street section. The storm
water combines with runoff in a downstream basin or is intercepted by a sump Type ‘R’ curb inlet. These
inlets discharge to one of the onsite storm drain systems.
There are two on site storm drain systems. Portions of Storm Line D will enter a Sand Filter for water
quality treatment. Other portions will outfall into Detention Pond D and another bioretention LID to provide
water quality treatment. Segments of Storm Line E will be treated with bioretention while other portions
will outfall into Detention Pond E and provide water quality treatment.
Street Capacity Analysis
The maximum encroachment for gutter flow, within the respective street sections and during the minor
storm (Q2) event was, used to establish the street capacity for. The maximum pavement encroachment
standards presented below in Table ST-2. For example, the minor storm flows within local streets cannot
overtop the curb (dmax=0.5’) or the crown of the street. During the major storm event (Q100), the street
capacities were estimated based on the maximum street encroachment standards presented below in
Table ST-3. As an example, the depth of water, for local streets, cannot six-(6) inches at the street crown.
Street capacity calculations for two-(2) different proposed ½ street sections and a range of longitudinal
grades are presented in Appendix C.

The minor storm event street capacity calculations were estimated with the Modified Manning Equation
and Excel. The major storm event street capacity calculations were completed using Bentley FlowMaster.
Refer to Appendix D for street capacity calculations.
Inlet Capacity Analysis
CDOT Type ‘R’ inlets are proposed throughout the project for removing excess developed runoff from the
right-of-way. The majority of these inlets are in sump. The minor and major storm event inlet capacities
were estimated with MHFD-Inlet_v5.01. The street section geometry and storm event encroachment limits
(i.e., street classification) established the maximum allowable ponding depth. We determined the inlet
length using the rational method flows at the respective design point and the maximum allowable ponding
depth. Appendix D includes capacity calculations for proposed Type ‘R’ curb inlets, which range in length
from 5’ to 20’.
Storm Drain Capacity Analysis
The storm drain system hydraulic analysis was completed using Bentley StormCAD V8i. This software
routes flows through each system by looking at the longest upstream tc at the manhole, calculating the
intensity and multiplying it by the upstream CA. Detailed output for each storm drain system analysis is
included in Appendix D.

VI. EROSION AND SEDIMENT CONTROL MEASURES
A General Permit for Stormwater Discharge Associated with Construction Activities issued by the
Colorado Department of Public Health and Environment (CDPHE), Water Quality Control Division
(WQCD), will be acquired for the site. A Stormwater Management Plan (SWMP) should be prepared to
identity the Best Management Practices (BMPs) which, when implemented, will meet the requirements of
said General Permit. Below is a summary of SWMP requirements which may be implemented on-site.
The following temporary BMPs may be installed and maintained to control on-site erosion and prevent
sediment from traveling off-site during construction:
· Silt Fence – a woven synthetic fabric that filters runoff. The silt fence is a temporary barrier that is
placed at the base of a disturbed area.
· Vehicle Tracking Control – a stabilized stone pad located at points of ingress and egress on a
construction site. The stone pad is designed to reduce the amount of mud transported onto public
roads by construction traffic.
· Straw Wattles – wattles act as a sediment filter. They are a temporary BMP and require proper
installation and maintenance to ensure their performance.
· Inlet protection – Inlet protection will be used on all existing and proposed storm inlets to help prevent
debris from entering the storm sewer system. Inlet protection generally consists of straw wattles or
block and gravel filters.
Construction Material & Equipment
The contractor shall store all construction materials and equipment and shall provide maintenance and
fueling of equipment in confined areas on-site from which runoff will be contained and filtered.
Maintenance
The temporary BMPs will be inspected by the contractor at a minimum of once every two weeks and after
each significant storm event.
The property owner will be responsible for routine and non-routine maintenance of the temporary BMPs.
Routine maintenance includes:
· Remove sediment from the bottom of the temporary sediment basin when accumulated sediment
occupies about 20% of the design volume or when sediment accumulation results in poor
drainage.
· Lawn mowing-maintain height of grass depending on aesthetic requirements.
· Debris and litter removal-remove debris and litter to minimize outlet clogging and improve
aesthetics as necessary.
· Inspection of the facility-inspect the facility annually to ensure that it functions as initially intended.
· Cleaning and repair of BMP’s is required when sediment has built up or the BMP is not working
properly.

VII. Conclusions
Compliance with Standards
The design presented in this drainage report for the Bloom development has been prepared in
accordance with the design standards and guidelines presented in the Fort Collins Stormwater Criteria
Manual.
Variances
1) Ch.6.1.1 Typical Release Rates: Allowable release rates during the 100-year storm event are limited
to the 2-year historic release rate, or less, as specially prescribed in the applicable Master Drainage
Plan.
Due to the site being existing farmland and relatively flat, the 2-year historic flow rates produce an
allowable flow rate of nearly 3.5 times less than the 0.2 cfs / acre criteria. Per the Master Drainage Plan, it
is stated to limit release into the lower Cooper Slough Area at the 100-year existing condition rate. The
adjacent development outfalling into the Cooper Slough is releasing in accordance with the 0.2 cfs / acre
criteria. It was also suggested per City Stormwater Engineering that flows outfalling further upstream will
help promote the hydraulic health of the Cooper Slough.
Summary of Concepts
The proposed storm drainage improvements should provide adequate protection for the developed site.
The proposed drainage system for the site should not negatively impact the existing downstream storm
drainage system.

Description
Hydrologic soil groups are based on estimates of runoff potential. Soils are
assigned to one of four groups according to the rate of water infiltration when the
soils are not protected by vegetation, are thoroughly wet, and receive
precipitation from long-duration storms.
The soils in the United States are assigned to four groups (A, B, C, and D) and
three dual classes (A/D, B/D, and C/D). The groups are defined as follows:
Group A. Soils having a high infiltration rate (low runoff potential) when
thoroughly wet. These consist mainly of deep, well drained to excessively
drained sands or gravelly sands. These soils have a high rate of water
transmission.
Group B. Soils having a moderate infiltration rate when thoroughly wet. These
consist chiefly of moderately deep or deep, moderately well drained or well
drained soils that have moderately fine texture to moderately coarse texture.
These soils have a moderate rate of water transmission.
Group C. Soils having a slow infiltration rate when thoroughly wet. These consist
chiefly of soils having a layer that impedes the downward movement of water or
soils of moderately fine texture or fine texture. These soils have a slow rate of
water transmission.
Group D. Soils having a very slow infiltration rate (high runoff potential) when
thoroughly wet. These consist chiefly of clays that have a high shrink-swell
potential, soils that have a high water table, soils that have a claypan or clay
layer at or near the surface, and soils that are shallow over nearly impervious
material. These soils have a very slow rate of water transmission.
If a soil is assigned to a dual hydrologic group (A/D, B/D, or C/D), the first letter is
for drained areas and the second is for undrained areas. Only the soils that in
their natural condition are in group D are assigned to dual classes.
