I. Introduction
General Location
The proposed Mulberry 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
Mulberry 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. It is currently a vacant and undeveloped tract of land
that is 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 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 southwest 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 that will help to determine the allowable release rates 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.
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.
Mulberry
Master Drainage Report
Galloway & Company, Inc.Page 5 of 15
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 east into the adjacent property and then to the Lake Canal.
Floodplain
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, a portion of the site lies within Zone AE, area subject to
inundation by the 1% annual chance flood. In Zone AE, the base flood elevations (BFEs) have been
determined. The project site lies within the flood zone area due to the existing Cooper Slough to the east
of the property and the portion of the Lake Canal that cuts across the southwest corner of the site.
A separate floodplain study will be prepared and will analyze the impact of the site on the existing
channel.

III. Project Description
The Mulberry 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 for 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 Mulberry) and southwest by various commercial developments.
This report summarizes the overall concepts for the development including any channel improvements
and proposed detention. The concepts will be further developed and additional detail regarding the
property will be included in future reports.

IV. Proposed Drainage Facilities
General Concept
Runoff from the developed site will be conveyed via overland flow, swales, 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 nine ponds that will provide detention for the site. Three of these ponds,
located on the east side of the site, will outfall directly into the Cooper Slough. One pond on the
southwest side of the site will outfall directly to the Lake Canal. The other five ponds will outfall to a
proposed storm line that will convey the flows south to a 30” RCP stub being provided with the Peakview
development. The storm plan from the Peakview Construction Drawings has been included in Appendix
B. Peakview has planned for 18 cfs from our site in this pipe and therefore that will control the overall
release rate from those ponds. This pipe outfalls west to Cooper Slough. In the future, when the master
plan improvements are complete, this pipe will be removed and the 4’x12’ box culvert under Greenfields
Drive will become operational. The Mulberry pond outfall pipe will be reconnected to the box culvert.
The project site has been divided into nine large basins, one for each detention pond. These basins will
be further subdivided as the drainage design progresses. The runoff from the basins and the sizing and
release rates for the proposed ponds have been preliminarily calculated with EPA SWMM 5.1. The model
assumes a medium density for planned single-family residential use (Basins A, B, D, and E), high density
for planned multi-family residential use (Basins C, F, and G) and commercial use for Basins H and I.
Pond A will outfall in Pond B which outfalls into Pond C which will then outfall directly into the Cooper
Slough. The release rate from Pond C will be less than the historic 2-year release rate from Basins A, B
and C (see Basins H1 and H2 in the existing conditions model). Pond I will outfall directly into the Lake
Canal at less than the 2-year historic release reate (see Basin H4 in the existing conditions model).
Ponds D, E, G, and H will outfall to the proposed storm line that outfalls to the Peakview stub that was
previously discussed. Pond F outfalls into Pond G. The combined release rate from Ponds D, E, G and H
will be less than 18 cfs. A summary of the preliminary pond volumes and release rates from the SWMM
model is included in Appendix C.
City of Fort Collins water quality and LID requirements will be met. The exact methodology is still being
determined but the site will likely use grass swales and water quality control volumes in the detention
ponds. Additional detail will be provided as proposed concepts for the site are refined.
There are no offsite basins that impact the project site.
There are no proposed improvements to the Cooper Slough associated with this development. A
separate floodplain report will be prepared to analyze the impact of the site on the channel.

V. Conclusions
Compliance with Standards
The design presented in this drainage report for the Mulberry development has been prepared in
accordance with the design standards and guidelines presented in the Fort Collins Stormwater Criteria
Manual.
Variances
There are no variances being requested at this time.
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.
