1.0 GENERAL LOCATION AND DESCRIPTION
1.1 Location
The proposed project is located within part of the south half of Section 23, in the Township 7
north, and the Range 69 west of the sixth principal meridian. The site is bound on the north and
east by the Larimer County Canal Number 2, on the northwest by Center Avenue, on the
southwest by Research Boulevard, and on the south by Drake Road.
1.2 Description of Property
The proposed project site is part of Colorado State University’s South Campus and includes the
current Tennis Complex. The property is approximately 20 acres in size.
Currently the site includes a tennis court facility with twelve tennis courts, a small parking lot,
and small building with restrooms. The remaining site is primarily vegetated in a mixture of
grasses. A depression at the western most corner of the property is populated with stands of
cottonwood trees. The existing topography slopes to the east at average slopes of between 0
and 3%. Soils in this area consist of Nunn clay loam which are classified as hydrologic group
“C”.
2.0 DRAINAGE BASINS AND SUB-BASINS
2.1 Major Basin Description
The project site is located in the City of Fort Collins Spring Creek drainage basin and is
identified as basins 89 and 62 in the Spring Creek master plan. Spring Creek lies north of the
project running west to east. The property is also part of Colorado State University’s South
Campus. The master plan for the south campus, completed by Anderson Consulting Engineers,
correlates to the City’s Spring Creek Master Plan’s drainage basin numbering. The proposed
project is outside any FEMA and City of Fort Collins floodplains areas.
2.2 Sub-Basin Description
2.2.1 Historical Drainage Patterns
Historically the northern two-thirds of the site drains to the east and the southern third drains to
the south. The northern portion drains to a detention pond at the northern and eastern sides of
the tennis courts. This detention pond discharges to the east under the Larimer County Canal
Number 2 and over to a drainage swale that runs north to Spring Creek.
3.0 DRAINAGE DESIGN CRITERIA
3.1 Regulations/Development Criteria
The preliminary design of the proposed drainage facilities was completed in accordance with the
criteria presented in the City of Fort Collins Spring Creek Basin Master Plan and Colorado State
University’s South Campus Drainage Master Plan. The following criteria were used in the
drainage design.
05.06.2015 2
The developed 100-year peak runoff from the developed site was limited to a release of
no greater 3.0 CFS based on the release rates identified for Pond 289 in the Spring
Creek and South Campus master plans.
The southern portion of the site remained undeveloped and was therefore not analyzed.
3.2 Hydrological Criteria
The design storm used was the 100-year (major) for the developed discharge. The City of Fort
Collins Intensity-Duration-Frequency curves were used to obtain rainfall data used for the 100-
year storm event. The runoff for the site was determined using EPA Storm Water Management
Model, version 5.1 (SWMM). This was done in order to accurately model the detention pond
because the FAA Method was not sufficient. The volume required in the detention pond
exceeded the limits of the FAA Method, therefore, SWMM was used to model the site.
3.3 Hydraulic Criteria
The stormwater conveyance systems were designed to capture and convey the major event to
the detention pond. The discharge used to size and design the conveyance structures was
based on the SWMM model of the discharges from the basins. Pipes were sized using SWMM
to ensure ponding at inlets met Fort Collins criteria.
Inlets and riprap were sized using Urban Drainage and Flood Control District’s spreadsheets
while maintaining Fort Collins’ ponding depth for inlet sizing and minimum riprap size where
applicable.
3.4 Waivers/Variance from Criteria
No waiver or variance is requested.
3.5 Stormwater Quality Considerations
In general, stormwater quality will be mitigated on-site during construction with the use of silt
fencing, vehicle tracking devices, inlet / outlet protection devices, and other best management
practices as needed. Long-term stormwater quality will be obtained by running the stormwater
over grassed areas and by providing a 40-hour water quality capture volume (WQCV) within the
detention pond in conjunction with a water quality orifice plate designed for a 12 hour release
rate.
4.0 WETLAND PRESERVATION AND MITIGATION
There are no jurisdictional wetlands located on this property.
5.0 DRAINAGE FACILITY DESIGN
5.1 General Concept
Onsite basins have been determined and are defined as Basins 1, 2, 3A through 3D, 4, 5, 6, 7A
through 7C, 8A through 8C. Basins that flow offsite include Basins OS-1, OS-2 and OS-3. No
offsite basins affect the project. Adjacent streets were accommodated in the Spring Creek
Master Plan and as such, onsite basins do not include adjacent roadways. The proposed
drainage patterns for the onsite basins have been determined by the layout and grading of the
05.06.2015 3
site. Overall, the site will be similar to the historic flow path. The majority of the stormwater from
the site will be routed through the site by the stormwater system to the detention pond. Due to
grading limitations, small portions of the site (the entrances, basins OS-1, OS-2, and OS-3)
drain out to the adjacent streets. Additionally, the south half of the south entrance drains
southerly without being detained, however, this flow pattern follows the South Campus and
Spring Creek master plans.
To mitigate the developed flows from the developed basins, the existing detention pond was
reduced to accommodate the developed flows leaving the site undetained while maintaining the
overall release rate from the site.
5.2 Hydrologic and Hydraulic Modeling
EPA SWMM 5.1 was used to determine runoff from each basin, route the flows, and then used
to size drainage structures to convey the discharge downstream. The model was also used to
ensure the detention pond had adequate volume to provide water quality and to provide
detention that detains the overall developed site flows with an overall release rate equal to the
historic 2-year flow rate of 3.0 cfs as required by the Spring Creek and South Campus master
plan. The rainfall from the City of Fort Collins Drainage Criteria was used in the SWMM model.
A summary of the SWMM parameters used in the model are listed in Table 5.1 below.

5.3 Basin Descriptions
Basin 1 consists mainly of the CSU tennis court and the newly graded detention pond 289. The
main drainage path will start on the surface of the CSU tennis courts, and will drain to the east
where it will hit the curb and gutter. It will then drain to the north east portion of the tennis courts
were water sheet flows directly into detention pond 289.
Basin 2 consists mainly of a new paved parking lot, with islands and curb and gutter. Runoff
sheet flows from west to east thru the parking lot until it reaches the curb and gutter. It will then
drain along the curb and gutter until it reaches the most northeast portion of the parking lot
where it enters Inlet-2, a double type-13 combination inlet. Flows are then conveyed via storm
sewer to pond 289.
Basins 3A, 3B, and 3D are very similar basins. All three basins consists of paved parking lots,
with islands and curb and gutter. Runoff in these sheet flows from east to west in the parking lot
until it reaches the curb and gutter. Flows will then be conveyed along the curb and gutter until
05.06.2015 4
it reaches the designated D-12 sidewalk culvert for the individual basin. The sidewalk culvert
will drain storm water to the west along a rundown until it reaches the bio-swale in basin 3C.
The bio-swale will drain to the north until it reaches the 18-inch pipeline under the north
entrance to the parking lot where it is conveyed into pond 289.
Basin 3C consists mainly of a bio-swale that slopes to then north at 0.5%. All the stormwater in
Basin 3C will be conveyed in the bio-swale, which will drain to the north until it reaches the 18-
inch pipeline under the north entrance to the parking lot where it is conveyed into pond 289.
Basin 4 consists primarily of new paved parking lot with islands and curb and gutter. Runoff will
sheet flow across the parking lot until it reaches the curb and gutter where it will then drain
along the curb and gutter until it reaches Inlet-4, a double type-13 combination inlet. Flows will
be conveyed into basin 8C’s bio-swale via storm sewer. It will then pass under the eastern
entrance flowing north into pond 289.
Basins 5 and 6 consists primarily of the proposed drive through the site connecting Research
Boulevard and Gillette Drive. Flows in both basins are conveyed via sheet flow until they reach
the curb and gutter in each respective basin where flows are then routed east to inlets 5 and 6.
Inlet 5 is a 10-foot type R inlet and Inlet 6 is a 5-foot Type R inlet. Both inlets are connected to
the storm sewer that conveys flow under the drive to the north into Pond 289.
Basins 7A and 7B are very similar basins. These basins consists of paved parking lots, with
Islands and curb and gutter. Runoff from these basins will begin at the eastern side of the
basin, and sheet flow westerly across the parking lot until it reaches the curb and gutter. It will
then drain along the curb and gutter until it reaches the designated D-12 sidewalk culvert for the
individual basin. The sidewalk culvert will drain storm water to the west along a rundown into
the bio-swale in Basin 7C. The bio-swale conveys the flows north until it drains into a grated
manhole in Basin 7C. The storm sewer system will deliver the flows into basin 8C’s bio-swale
and ultimately into Pond 289.
Basin 7C consists mainly of landscaped area. All the stormwater in Basin 7C will drain into a
grated manhole section at the northern end of the basin. The storm sewer system will convey
flows into basin 8C’s bio-swale and ultimately into Pond 289.
Basin 8A consists of paved parking lot with islands and curb and gutter. Runoff from this basin
will sheet flow east across the parking lot until it reaches the curb and gutter, from where it will
drain north along until it reaches Inlet-8A, a double type-13 combination inlet. The flow will then
flow through a flared end section and will enter a bio-swale. Once flows enter the bio-swale in
Basin 8C, flows are conveyed north and into Pond 289.
Basin 8B consists primarily of a new paved parking lot with islands and curb and gutter. The
runoff is conveyed via sheet flow east-southeasterly across the parking lot until it reaches the
curb and gutter. It will then drain flow along the curb and gutter until it reaches the D-12
sidewalk culvert at the southeast portion of the basin. The curb cut will drain storm water to the
east along a rundown until it reaches the bio-swale in basin 8C. The bio-swale will then drain
north at 0.5% until it reaches the storm sewer system that conveys the flows north into pond
289.
05.06.2015 5
Basin 8C consists mainly of a bio-swale that is sloped to the north at 0.5%. All the stormwater
runoff in Basin 8C will be conveyed by the bio-swale to the north until it reaches the storm sewer
system where it is conveyed north into pond 289.
Basin OS-1 consists primarily of the north entrance to the site. The flows from this basin are
conveyed via sheet flow to the adjacent street where they leave the site.
Basin OS-2 consists primarily of the main entrance off of Research. The flows from this basin
are conveyed via sheet flow to the adjacent street where they leave the site.
Basin OS-3 consists primarily of the main entrance off of Gillette. The flows from this basin are
conveyed via sheet flow to the adjacent street where they leave the site.
As each basin contributed to the total discharge for each conveyance, the routed summation of
the contributing discharges was used to size the conveyance structures at key points. See
Table 5.2 for a summary of the drainage basins and their characteristics.

5.4 Detention Pond
The existing detention pond was enlarged with the proposed parking lot improvements. The
new pond includes the required detention to release at a reduced flow rate and the storage for
the 40-hr release rate for water quality. The outlet is a siphon that was designed with the
previous tennis courts improvements. Because the detention pond was modified, the outlet
structure will need to be re-constructed to have a water quality orifice plate sized to release the
WQCV within 12 hours and the revised release rate accounted for with a new orifice plate. If
the outlet structure should ever become plugged, the volume in the pond is large enough to
contain the developed runoff from the site without overtopping the spillway. The existing
spillway was not modified. The following table summarizes the calculated stormwater runoff
quantities and pond design parameters. See Table 5.3

5.5 Low Impact Development
Low impact development (LID) was used as much as possible including in the bio-swales on the
east and west sides of the site and in the parking islands. The overall water quality control
volume was not reduced even though some areas do receive some treatment by the bio-swales
and parking islands. The reason for this is that it is unclear how effective the small scale LID
improvements are. Should they be found ineffective in this application, the additional capacity in
the pond is available. The overall impact to the pond volume is fairly minor but it would remove
basins 3A, 3B, 3C, 7A, 8B, and 8C and result in a total requirement of .420 acre-feet of WQCV
storage instead of the 0.492 identified using all the basins.
6.0 CONCLUSIONS
Overall, the design of the structures used to convey the runoff from the proposed development
will control required storm events effectively. The proposed stormwater system will capture the
majority of the increased runoff from the site and route the storm flows to the detention pond.
The detention pond will attenuate the developed flows and release them at a controlled rate to
the Spring Creek basin. Water quality control will be provided before discharging developed
flows. No offsite drainage improvements are required.

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.

Survey Area Data: Version 9, Sep 22, 2014
Soil map units are labeled (as space allows) for map scales 1:50,000
or larger.
Date(s) aerial images were photographed: Apr 22, 2011—Nov 18,
2011
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.
