RE: Magnolia Place Dormitory
Dear Mr. Thompson,
September 19, 2001
Mitchell & Morgan, LLP has completed the Fire Flow Analysis for the
Magnolia Place Dormitory Building. The building will be located between the
existing Polo Club Apartments at 700 Dominik Drive and The Gables
Apartments at 401 University Oaks Blvd between University Oaks and
Dominik Drive. The front entrance of the dormitory will face University Oaks
Blvd., while the rear will face Dominik Drive.
The existing utilities consist of an 8" water line along Dominik Drive and an 8"
water line along University Oaks Blvd. The two existing lines will be
connected by an 8" water line running through the Magnolia Place Dormitory
site .
Domestic use flow was calculated by using an average of 115 gpd per capita.
The Dormitory contains approximately 541 beds, giving a total flow of 43 gpm.
Using the BOSS EMS water distribution modeling program, the pressure was
found to be approximately 77.8 psi.
The building will be partitioned into four separate sprinkler areas, with the
maximum sprinkler area of27,706 fi:2. The fire flow was calculated by using the
following formula obtained from the College Station Fire Development Fire
Prevention Division Construction & Development Guide:
Where:
Fire Flow= 18 * C *(A) 0·5
C = Coefficient related to the type of construction
1.5 for wood frame construction
1. 0 for ordinary construction
0.9 for heavy timber type construction
0.8 for noncombustible construction
0.6 for fire-resistive construction
A = The total floor area in square feet (including all stories,
but excluding basements).

The maximum zone area, zone 1 as seen on the attached exhibit, was used in
calculating the fire flow for the dormitory.
Fire Flow = 18* l .0*(75682) o.s = 5000 gpm
The ISO allows for a reduction of 50% in the fire flow if the area contains a
completely automatic sprinkler protection throughout the building. Since the
Magnolia Place Dormitory will contain an automatic sprinkler system, the fire
flow can be reduced by 50% to 2500 gpm.
After the reduction the fire flow must then have an exposure protection value
added to it.

After distances from the dormitory to the property lines were measured, the sum
of the percentages was 30%. Therefore,
(2500 gpm * 0.3) + 2500 gpm = 3250 gpm
A minimum pressure of20 psi is required to prevent the development of
negative pressure in street mains. Adding the fire flow and the domestic flow
results of a flow of3293 gpm. Using the BOSS EMS water distribution
modeling program, the pressure under this fire flow was approximately 38.3 psi.
The following table indicates the total flow for each zone. Refer to the attached
diagram for zone location.

Given the above analysis, the fire flow and domestic water requirements can be
met for Magnolia Place Dormitory with the addition of our internal 8 inch
waterline connected to the 8" lines on Dominik Drive and University Oaks
Blvd.

Re: Magnolia Place Dormitory Drainage Analysis
81-l. I cf·
Attached is a copy of a correction that we made to the Magnolia Place Dormitory
Drainage Analysis. We found an error in the drainage report in that it did not
reflect a change that was made to the drawings. The changes are as follows:
• DA3-6 goes to JB2 not DA3-7 which affected the total CA of DA3-7
to JB2
• Because of the steep slope required for the JB2 to JB3 line as an
18"line, this line was changed to 24" to allow for a flatter slope
Both of these items were changed prior to the approval of the plans and the
drainage report was simply not changed to reflect this. This copy is for your
records. If you have any questions please call.

MAGNOLIA PLACE D ORMITORY
DRAINAGE ANALYSIS
INTRODUCTION
This storm drainage report is written to document and analyze the necessary
drainage infrastructure for the Magnolia Place Dormitory project. This project is located
in College Station between Dominik Drive and University Oaks Boulevard. It will be
constructed adjacent to two existing multi-family projects, namely, the Polo Club
Apartments to the east and the Gable Apartments to the west.
The parameters used for design and analysis of pre-vs. post-developed conditions
are incorporated to show how the final drainage design will accomplish the desired
drainage objectives per the City of College Station Drainage Policy and Design Standards
(DPDS).
GENERAL LOCATION AND DESCRIPTION
This project is located on Lots 1 & 2, Block A of the Regency Village
Subdivision. The project consists of a three story private dormitory with an associated
parking surface parking lot. Because of the concerns with the neighboring single-family
residential area, the dormitory is oriented on the property such that it takes its major
access from University Oaks Boulevard. This should help minimize the amount of traffic
using Dominik Drive. Because of the project size, site size, the amount of required
parking and the desire to keep detention out of the parking lot, the project was designed
with an underground detention system. This system consists of a series of 66-inch
corrugated metal pipes, which provide storage for the 5-year through 100-year storms.
This system is located on the most downstream portion of the site, which is the southeast
comer of the property. From this underground detention system, the discharge is
conveyed through a 15-inch PVC discharge pipe. This discharge pipe is constructed from
the site down the University Oaks right-of-way to an existing storm sewer junction box,
which is located in the center of the University Oaks Street near the intersection with
Stallings Drive. It increases in size from the 15-inch PVC to a 24-inch RCP shortly after
2 Magnolia Place Dormitory
leaving the underground detention system in order to eliminate head losses associated
with pressure flow. The 15-inch pipe is designed to act only as an orifice for the control
structure and will not be the primary conduit.
PRIMARY DRAINAGE BASIN DESCRIPTION
As seen on Exhibit A, this property is located within the Wolf Pen Creek
Drainage Basin, with a minor portion of the site contributing to Wolf Pen Creek
Tributary "B'' and the majority of the site contributes to Tributary "A" of Wolf Pen
Creek. Tributary "A" is located within the City of College Station's Oaks Park at the
intersection of University Oaks and Stallings Drive. This exhibit also illustrates that no
portion of the site lies within the 100-year floodplain per the Federal Emergency
Management Agency Flood Insurance Rate Map Panel 144, with an effective date of July
1992.
DRAINAGE DESIGN CRITERIA
All drainage design is in accordance with the City of College Station DPDS. As such:
• The design rainstorm events used are the 5 through 100-year events to analyze the
effectiveness of the detention pond design;
• Because the site size is less than 50 acres, flow calculations are based on the
Rational Method, with a minimum time of concentration of 10 minutes; and
• Because the site size is less than 50 acres, the hydrograph methodology used is
the triangular approximation method.
DRAINAGE FACILITY DESIGN
Predevelopment Drainage Patterns
The site is currently vacant and the pre-developed runoff patterns contribute to
both University Oaks Boulevard and Dominik Drive. Approximately .95 acres flow to
the northwest along Dominik Drive, while the majority of the site (7.15 acres) flows to
the southeast toward University Oaks Boulevard. Because of the location of this property
on a ridge between two creek tributaries, there are no offsite areas that flow through the
site. The pre-developed drainage area and runoff patterns can be seen on Exhibit B-1.
3 Magnolia Place Dormitory
Predevelopment Drainage Patterns
The post-developed drainage areas and runoff patterns are illustrated on Exhibit
B-2. As seen on the exhibit, Drainage Areas 1 & 2 have been reduced in size. This size
reduction has been accomplished to account for the increased impervious cover and to
assure that the undetained flow from these two areas matches the pre-developed rate of
runoff. As seen on Exhibit C-1 the pre-vs. post-developed runoff for each of these areas
has been decreased. As a result, Drainage Area 3 increased in size from 5.45 acres to
7.21 acres.
The pre-vs. post-developed runoff values for drainage areas 1 & 2 are as follows:
Peak Discharge From Magnolia Place Dormitory
Location 5-Year(cfs) 10-Year(cfs) 25-Y ear( cfs) 50-Year(cfs) 100-Year( cfs)
Pre-Developed 5.2 5.9 6.7 7.6 8.5
(Area 1)
Post-Developed 2.6 2.9 3.3 3.7 4.2
(Area 1)
Pre-Developed 2.9 3.3 3.7 4.2 4.7
(Area 2)
Post-Developed 2.5 2.9 3.3 3.7 4.1
(Area 2)
Underground Detention Facility
The underground detention facility consists of a network of fourteen 66-inch corrugated
metal pipes connected at the east end of the property by a series of manifolds joined
together with coupling bands. In addition there is a 24" diameter equalizer running
through the middle of the pipes that aids in distributing the stormwater. Each 66" CMP is
157 feet in length creating a total storage volume, neglecting the equalizer volume, of
4 Magnolia Place Dormitory
approximately 54800 cu-ft. This volume is well in excess of the amount required for the
100-year storm but required in order to attenuate lesser storms properly. As specified
earlier, the event flow calculations were done using the rational method and the
hydrographs were completed using the triangle approximation method. The volumes for
each storm was calculated by overlaying the pre-development and post-development
hydrographs, and then taking the difference in the areas up to the point of recession. This
was repeated for each of the storms. The 10-year and 100-year calculations are available
as part of Exhibit D. The controlling structure in the underground detention system is the
15-inch PVC pipe connected to the junction box at the southeast end of the property. The
flow through the pipe was calculated using the orifice equation. Despite being sized to
handle a 100-year event, however, as noted above, storage has been added to the system
to handle lesser storms.
CONCLUSION
The improvements associated with the Magnolia Place Dormitory improvements
effectively control the runoff to the two Wolf Pen Tributaries. Although the calculations
do not include routing the hydrographs through the underground detention system, the
methodology used to calculate the peak discharge from the pre-vs. post-developed
scenario and assuring that the underground volume is sufficient to handle the difference
between these hydrographs is conservative. The discharge pipe size calculations were
based upon the 100-year event, given the maximum ponded depth (head) on the discharge
pipe. Subsequently all storm events (5-year through 100-year) were checked to assure
that the volume provided was adequate. The underground detention pond performs
satisfactorily for all storm events.
