ARBORS AT WOLF PEN CREEK
College Station, Brazos County, Texas

SUMMARY
The project js situated off Holleman Drive and Lassje Lane jn College Station, Brazos County,
Texas. It js the intended site for the Arbors at Wolf Pen Creek Apartment Complex to be
estabHs hed wjthln the bounds of the 8.49 acre tract.
The total drainage area tributary to the project is 9.90 acres. The pre-development run-off
coefficjent was estimated to be 0.40. A conservative estimate of the post-development run-off
coefficient, incorporating the nature of the site improvements planned, was taken to be 0.75 across
the entire site.
The site has been broken up into four (4) areas for drainage analysis purposes . (See Site Plan.)
Run-off from three (3) of these drainage areas, a total of 7.63 acres of the property, is collected
and empties into a proposed underground storm sewer. This pipe will flow into Wolf Pen Creek,
an improved primary channel of the City of College Station's drainage network Surface drainage
generated on the remaining 2.27 acres will "free-flow" off site. By incorporating the underground
storm sewer, the run-off flows to the adjacent property will actual ly be less than before
development. The majority of the water will bypass surface flow and be collected directly into the
proposed underground conduit entering Wolf Pen Creek approximately 300 feet away.
The computations are as follows: based on the total tributary drainage area of the project being
estimated at 9 .90 acres, the pre-development run-off coefficient being assumed at 0.40, and a
minimum time of concentration of 10 minutes, the relative pre-development peak discharge rate
("Q") was determined. The Rational Method was utilized to compute the estimated peak pre-
development discharge rates. The equation tl1at represents the Rational Method is as follows: Q =
CIA. "Q" is the peak discharge rate in cubic feet per seco nd, "C" is the run-off coefficient,
assumed to be 0.40 in the pre-development condition, "I" is the storm intensity in inches per hour,
and "A" is the area of the corresponding basin in acres.
Based on the same tributary area of 9.90 acres, tl1e post-development run-off coefficient being
assumed at 0.75, and a minimum time of concentration of 10 minutes, the relative post-
development peak discharge rate ("Q") was determined using the same minimum time of
concentration of 10 minutes. The Rational Method was again employed to compute the estimated
peak post-development discharge rates. The form ula is as follows: Q = CIA, where; "Q" is the
peak discharge rate in cubic feet per second. "C" is the run-off coefficient, in the post-development
condition "C" is assumed to be 0.75, "I" is the storm intensity in inches per hour, and "A" is the
area of the corresponding basin in acres.
The comparison between the peak pre-development discharge rate and post-development discharge
rate is included. Also the corresponding volumes are approximated by simply determining the
volumes generated from the difference of the pre-development and post-development hydrographs.
See the appendix for pre-development and post-development hydrographs. Please note that the
post-development hydrographs show no detention.
Initially, drainage computations are broken down into surface run-off ("free-flow") and the total
flow entering the storm sewer. From the "inflow" rate and time of concentration (10 minutes
minimum), hydrographs were compiled to graphically represent flow concentrations. (See
Appendix.) The hydrographs are triangular in shape and are based on the standard SCS unit
hydrograph with time to peak set equal to the time of concentration and the total time base set at
3.00 times the time of concentration. (Please note that a 30 minute total storm event duration was
utilized exclusively throughout this report.) Tabulations of the pre-development hydrograph and
the post-development hydrograph graphing ordinates are also included in addition to the
hydrographs themselves. (See Appendix.)
The total post-development mn-off entering the proposed underground conduit is further broken
down into three sections according to the corresponding sewer inlet (See attached Site Plan.) A
comparison of pre-development and post-development run-off for each of these sections is
provided. Inlet 1 collects flow from a 3.62 acre section of the site. Inlet 2 and Inlet 3 drain water
off the remaining 1.57 acres and 2.44 acre sections, respectively. Storm sewer inlets and total
pipe diameter are sized according to peak flow rates for the 100-year storm event and are shown in
more detail in the Storm Sewer Capacity Calculations section of this report. The proposed
configuration consists of a 30" R.C.P. running between Inlets 1 & 2 followed by a 36" R.C.P.
between Inlets 2 & 3 and continuing on to the Wolf Pen Creek Channel.
In closing, total post-development peak discharge from the site is less than the pre-development due
to the incorporation of the underground storm facilities. The subsequent peak post-development
surface discharge rates and velocities projected are well within reasonable limits and should not
present any problems downstream. The proposed underground conduit is sized to readily handle
100-year storm peak flow conditions and provide effective transport of the runoff to the Wolf Pen
Creek.

highest flowrate, the inlets provide capacity beyond the flows expected with the 100-
year storm event and will not overflow the curb.

RE: REVISIONS TO DRAINAGE REPORT FOR ARBORS AT WOLF PEN CREEK,
COLLEGE STATION, BRAZOS COUN1Y, TEXAS.
Dear Veronica,
I wanted to let you know that the comments to the drainage report for the
a bove referenced project that we discussed earlier this week have been addressed
and are reflected in this latest submittal. The storm sewer calculations are
consistent with latest plans and show proposed Inlets 2 and 3 to have one
extension each providing a total of 10.0 feet of inlet length at these respective
loca tions. (Your copies of the plans do not show the Inlet 2 change yet, but the
originals have all been modified.) Initially, the storm sewer design called for all
three inlets to have two extensions each (providing 15.0 feet of inlet length at
each). However, in considering the lower expected flows at Inlets 2 & 3 and other
factors, the plans were changed to show Inlets 2 & 3 with only one extension each.
I am including the pages you redlined to facilitate your review. The letter
mentioned concerning the issue of "no detention" will be following shortly. Also, if
this submittal is s a tisfactory, it would helpful to have a ny old copies that you do
not need ret urned to us. Thank you .

SUMMARY
The project is situated off Holleman Drive and Lassie Lane in College Station, Brazos County,
Texas. It is the intended site for the Arbors at Wolf Pen Creek Apartment Complex to be
established within the bounds of the 9.90 acre tract.
The total drainage area tributary to the project is 9.90 acres. The pre-development run-off
coefficient was estimated to be 0.40. A conservative estimate of the post-development run-off
coefficient, incorporating the nature of the site improvements planned, was taken to be 0.75 across
th e entire site .
No detention will be necessary for this project. The site has been broken up into four (4) areas for
drainage analysis purposes. (See Site Plan.) Run-off from three (3) of these drainage areas, a total
of 7 .63 acres of the property, is collected and emptys into a 30" underground storm sewer. This
pipe will flow into Wolf Pen Creek, an improved primary channel of the City of College Station's
drainage network. Surface drainage generated on the remaining 2.27 acres will "free-flow" across
the project site unmetered to downstream adjacent properties. By incorporating the underground
storm sewer, the run-off flows to the adjacent properties will actually be less than before
development. The majority of the water will bypass surface flow and be collected directly into the
30" pipe and enter Wolf Pen Creek approximately 300 feet away.
The computations are as follows: based on the total tributary drainage area of the project being
estimated at 9.90 acres , the pre-development run-off coefficient being assumed at 0.40, and a
minimum time of concentration of 10 minutes, the relative pre-development peak discharge rate
("Q") was determined. The Rational Method was utilized to compute the estimated peak pre-
development discharge rates. The equation that represents the Rational Method is as follows: Q =
CIA. "Q" is the peak discharge rate in cubic feet per second, "C" is the run-off coefficient,
assumed to be 0.40 in the pre-development condition, "I" is the storm intensity in inches per hour ,
and "A" is the area of the corresponding basin in acres.
Based on the same tributary area of 9.90 acres, the post-development run-off coefficient being
assumed at 0.75, and a minimum time of concentration of 10 minutes, the relative post-
development peak discharge rate ("Q") was determined usin g the same minimum time of
concentration of 10 minutes. The Rational Method was again employed to compute the estimated
peak post-development discharge rates . The formula is as follows : Q = CIA, where; "Q" is the
peak discharge rate in cubic feet per second. "C" is the run-off coefficient, in the post-development
condition "C" is assumed to be 0.75, "I" is the storm intensity in inches per hour, and "A" is the
area of the corresponding basin in acres.
The comparison between the peak pre-development discharge rate and post-development discharge
rate is included. Also the corresponding volumes are approximated by simply determining the
volumes generated from the difference of the pre-development and post-development hydrographs.
See the following pages for pre-development and post-development hydrographs. Please note that
the post-development hydrograph shown on these same graphs assumes no detention.
Initially, drainage computations are broken down into surface run-off ("free-flow") and the total
flow entering the storm sewer. From the "inflow" rate and time of concentration (10 minutes
minimum), hydrographs were compiled to graphically represent flow concentrations. The
hydrographs are triangular in shape and are based on the standard SCS unit hydrograph with time
to peak set equal to the time of concentration and the total time base set at 3.00 times the time of
concentration. (Please note that a 30 minute total storm event duration was utilized exclusively
throughout this report.) Tabulations of the pre-development hydrograph and the post-development
hydrograph graphing ordinates are included as well as the hydrographs themselves.
In the following pages, the total post-development run-off entering the 30" pipe is further broken
down into three sections according to the corresponding sewer inlet. (See attached Site Plan.) A
comparison of pre-development and post-development run-off for each of these sections is
provided. Inlet 1 collects flow from a 3.62 acre section of the site. Inlet 2 and Inlet 3 drain water
off the other 1.57 acres and 2.44 acre sections, respectively. Storm sewer inlets and total pipe
diameter are sized according to peak flow rates for the 100-year storm event and are shown in
more detail in the Storm Sewer Capacity Calculations section.
In closing, total post-development peak discharge from the site is less than the pre-development due
to the incorporation of the underground storm facilities. The subsequent peak post-development
surface discharge rates and velocities projected fall easily within reasonable limits and should not
present effect any downstream .
Storm Sewer Capacity Calculations
1.) DETERMINE STORM SEWER INLET SIZE:
Q = CLH3/2 (Weir Equation)
Where,
C = Weir Coefficient = 3.0
H = Drop Height at Opening = 10.00 inches = 0.833 feet
Q = Flow Rate (ft3/s)
L = Weir Length (width of opening in feet)

Q at Inlet 1 = 31.52 ft3/s (cubic feet per second) ..../ Cantrof.s
Q at Inlet 2 = 13.77 ft3/s (cubic feet per second)
Q at Inlet 3 = 21.25 ft3/s (cubic feet per second)
Solve for Weir Length (ft):

Note:
Water at these storm sewer inlets will be less than 6 inches deep. The inlets are
sized according to designflowsfor the 100-Year storm conditions. Even at Inlet
1, with the highest flowrate, the inlets provide capacity beyond the flows
expected with the 100-year storm event and will not overflow the curb.

RE: WATER (DOMESTIC) AND SANITARY SEWER LoADING FOR
ARBORS AT WOLF PEN CREEK, COLLEGE STATION, BRAZOS COUNTY, TEXAS.
'
Dear Veronica,
Enclosed herewith are computations projecting the peak loading for water
(domestic) and sanitary sewer for the above referenced project. Sanitary Sewer
Loading will be calculated based on a direct 1: 1 ratio between water (domestic)
usage and sanitary sewer discharge.
The project calls for 292 bedrooms yielding a total occupancy of 292 persons
at an assumed standard average of one (1) person per room. However, considering
the nature of the project and the fact that College Station is a college town, it
seems both reasonable and safe to double the design occupancy value to an
average of two (2) persons per bedroom. Therefore, a more realistic determination
of 584 occupants is used in the calculations. At 100 gallons per day design usage,
584 occupants equates to 58,400 gallons per day. Peaking 58,400 gallons per day
by a factor of three (3) yields 175,200 gallons per day or 0 .271 cubic feet per_V
second peak fl oW" rate. (121.67"gallons per minute) It is anticipated that a six (6)
inch diameter water line will "loop" through the project connecting to the existing
eight (8) inch diameter water line running along the northwest side of Holleman
Drive.
Utilizing Manning's Equation. Flow Rate = (l .486/n)(AR213 S 112), full flow
capacity of a six (6) inch diameter water line is estimated at 0.397 cubic
feet/second at a mean velocity of 2.02 ft/sec. Please note that the slope of the
aforementioned six (6) inch diameter water line was assumed to be 0.005 ft/ft or
0.50% grade. The actual flow capacity will be much higher as the flow will be
"pressurized". It can be seen from the data presented above that a six (6) in
diameter water line will be more than adequate for the anticipated domestic flows .

Sanitary Sewer Loading is directly proportionate t o the domestic water flow with
the exception of infiltration. An a d ditional 10 % of the calculated d omestic water
peak fl ow rate will be added to the peak b ase fl ow and used to determined the
peak discharge rate for sanitary sewer loading.
0 .271 ft3/sec + (0 .271) x (0 .0 1) = 0 .298 ft3 /sec. V

Arbors of Wolf Pen Creek
Case #95-505
From: Steve Homeyer #
Graduate Engineer
After speaking with Jon Mies of the fire department about the placement of fire
lanes, he was concerned about the possibility of the Arbors complex having a
security entrance in the future . If this were the case, then all radii in the complex
would have to be designed to accommodate the ladder truck. Also, he and I
noticed that there were not enough fire hydrants to adequately protect the
complex. I spoke with Edward Stefoniak of WSI Architects about the fire lanes
and faxed him a copy of the layout Jon and I created . I also mentioned the
security entrance and he stated that the idea had surfaced but the owners did
not feel it would be necessary due to the complex being occupied primarily by
college students . I then indicated that if there were plans to install security
gates, then they would need to be addressed at this time . I also told him of the
need to either see if they could move the hydrants around to insure protection or
simply add another one somewhere around building 1.11 .

This is something tha t Veronica got started a couple of months ago. When construction staking started out
there, '1 er<J n ica noticed tha t one of the inlets appeared to be in the middle of a driveway and she asked that
Garrett Eng .. c.l18 ck i nto it. Sure enough there wa o a problem and Garrett had to mc ve and/or redesign t he
inlet. What you h ave is Garrett'e attempt to do that.
it doesn't matter 1 Garrett took almost two months to redesign this and now they want us to push
1 · =lse to get it out. Treat it like you would any other rep ort or set of plans.

Are any of you fam i ~iar with what came in last Thursday? It looks like revised drainage calculations. If
so , please either take a look at it or give me some Lackgrou nd information so that I can review it.

ARBORS AT WOLF PEN CREEK
College Station, Brazos County, Texas
* September, 1995 *
SUMMARY
The project is situated off Holleman Drive and Lassie Lane in College Station, Brazos County,
Texas. It is the intended site for the Arbors at Wolf Pen Creek Apartment Complex to be
established within the bounds of the 9.90 acre tract.
The total drainage area tributary to the project is 9.90 acres. The pre-development run-off
coefficient was estimated to be 0.40. A conservative estimate of the post-development run-off
coefficient, incorporating the nature of the site improvements planned, was taken to be 0 .75 across
the entire site.
No detention will be necessary for this project. The site has been broken up into four (4) areas for
drainage analysis purposes. (See Site Plan.) Run-off from three (3) of these drainage areas, a total
of 7 .63 acres of the property, is collected and emptys into a 30" underground storm sewer. This
pipe will flow into Wolf Pen Creek, an improved primary channel of the City of College Station's
drainage network Surface drainage generated on the remaining 2.27 acres will "free-flow" across
the project site unmetered to downstream adjacent properties. By incorporating the underground
storm sewer, the run-off flows to the adjacent properties will actually be less than before
development. The majority of the water will bypass surface flow and be collected directly into the
30" pipe and enter Wolf Pen Creek approximately 300 feet away.
The computations are as follows : based on the total tributary drainage area of the project being
estimated at 9.90 acres, the pre-development run-off coefficient being assumed at 0.40, and a
minimum time of concentration of 10 minutes, the relative pre-development peak discharge rate
("Q") was determined. The Rational Method was utilized to compute the estimated peak pre-
development discharge rates. The equation that represents the Rational Method is as follows: Q =
CIA. "Q" is the peak discharge rate in cubic feet per second, "C" is the run-off coefficient,
assumed to be 0.40 in the pre-development condition, "I" is the storm intensity in inches per hour,
and "A" is the area of the corresponding basin in acres.
Based on the same tributary area of 9.90 acres, the post-development run-off coefficient being
assumed at 0.75, and a minimum time of concentration of 10 minutes, the relative post-
development peak discharge rate ("Q") was determined using the same minimum time of
concentration of 10 minutes. The Rational Method was agai n employed to compute the estimated
peak post-development discharge rates. The formula is as follows: Q = CIA, where; "Q" is the
peak discharge rate in cubic feet per second. "C" is the run-off coefficient, in the post-development
condition "C" is assumed to be 0.75, "I" is the storm intensity in inches per hour, and "A" is the
area of the corresponding basin in acres .
The comparison between the peak pre-development discharge rate and post-development discharge
rate is included. Also the corresponding volumes are approximated by simply determining the
volumes generated from the difference of the pre-development and post-development hydrographs .
See the following pages for pre-development and post-development hydrographs. Please note that
the post-development hydrograph shown on these same graphs assumes no detention.
Initially, drainage computations are broken down into surface run-off ("free-flow") and the total
flow entering the storm sewer. From the "inflow" rate and time of concentration (10 minutes
minimum), hydrographs were compiled to graphically represent flow concentrations. The
hydrographs are triangular in shape and are based on the standard SCS unit hydrograph with time
to peak set equal to the time of concentration and the total time base set at 3.00 times the time of
concentration. (Please note that a 30 minute total storm event duration was utilized exclusively
throughout this report.) Tabulations of the pre-development hydrograph and the post-development
hydrograph graphing ordinates are included as well as the hydrographs themselves.
In the following pages, the total post-development run-off entering the 30" pipe is further broken
down into three sections according to the corresponding sewer inlet. (See attached Site Plan.) A
comparison of pre-development and post-development run-off for each of these sections is
provided. Inlet 1 collects flow from a 3.62 acre section of the site. Inlet 2 and Inlet 3 drain water
off the other 1.57 acres and 2.44 acre sections, respectively. Storm sewer inlets and total pipe
diameter are sized according to peak flow rates for the 100-year storm event and are shown in
more detail in the Storm Sewer Capacity Calculations section.
In closing, total post-development peak discharge from the site is less than the pre-development due
to the incorporation of the underground storm facilities . The subsequent peak post-development
surface discharge rates and velocities projected fall easily within reasonable limits and should not
present effect any downstream.

Storm Sewer Capacity Calculations
1.) DETERMINE STORM SEWER INLET SIZE:
Q = CLH3/2 (Weir Equation)
Where,
C = Weir Coefficient = 3.0
H = Drop Height at Opening = 10.00 inches = 0.833 feet
Q = Flow Rate (ft3/s)
L = Weir Length (width of opening in feet)
100-Year Storm Peak Flow Rates (Q):
Q at Inlet 1 = 31.52 ft3 /s (cubic feet per second) "' Controfs
Q at Inlet 2 = 13.77 ft3/s (cubic feet per second)
Q at Inlet 3 = 21.25 ft3/s (cubic feet per second)
Solve for Weir Length (ft):
Inlet 1: I
L = Q/CH312 = 31.52 I (3.0 * (10/12) 312)
L = 13.81 feet --~qu.irea
L = 15 .00 feet --ProvUfea (3 rectangular box inlets @ 5' width each)
Inlet 2: I
L = Q/CH312 = 13 .77 I (3.0 * (10112) 3/2)
L = 6.03 feet --~qu.iretf
L = 15.00 feet --ProvUfetf (3 rectangular box inlets@ 5' width each)
Inlet 3: I
L = Q/CH312 = 21.75 I (3 .0 * (10/12) 3/2)
L = 9. 31 feet --~qu.iretf
L = 15.00 feet --ProvUfetf (3 rectangular box inlets @ 5' width each)
Note:
Water at these storm sewer inlets wiU be less than 6 inches deep. The inlets are
sized according to designjlowsfor the 100-Year storm conditions. Even at Inlet
1 , with the highest jlowrate, the inlets provide capacity beyond the flows
expected with the 100-year storm event and wiU not oveTjlow the curb.

Where,
n = Manning's Coefficient (for concrete = 0.0013)
R = Hydraulic Radius (ft) -d/4 for round, full pipe
S = Pipe Slope (feet per feet)
Q = Flow Rate (ft3/s)
A = Cross-Sectional Area of Flow (ft2) -nd2!4

30" R.C.P.(Velocity) => 6.47 ft/s
At Inlet 2: Q = 31.52 ft3/s + 13. 77 ft3/s = 45 .29 ft3/s --!J<i-quirea
30" R.C.P. @ 2.00 % slope => 58 .01 ft3/s

36" R.C.P. @ 0.60% slope => 51.66 ft3/s --J - -Provitfuf
36" R.C.P.(Velocity) => 7 .31 ft/s
At Inlet 3: Q = 31.52 ft3/s + 13 .77 ft3/s + 21.25 ft3/s = 66.54 ft3/s --!J<i-quirea
30" R.C.P . @ 2 .00% drop => 58.01 ft3/s
30" R.C.P.(Velocity) => 11.81 ft/s

30" R.C.P .(Velocity) => 13.21 ft/s
36" R.C.P . @ 1.00% drop => 66.70 ft3/s --J --Provitfuf
36" R.C.P .(Velocity) => 9.43 ft/s
Note:
AU pipe sizing meet capacities above the projections for the 100-year storm flow
conditions and velocities remain less than 10.0 ft! s in pipe sections.

ARBORS AT WOLF PEN CREEK
College Station, Brazos County, Texas
*September, 1995 *
SUMMARY
The project is situated off Holleman Drive and Lassie Lane in College Station, Brazos County,
Texas. It is the intended site for the Arbors at Wolf Pen Creek Apartment Complex to be
established within the bounds of the 8.49 acre tract.
The total drainage area tributary to~ project is 9.90 acres. The pre-development run-off
coefficient was estimated to be _0.40. A conservative estimate of the post-development run-off
coefficient, incorporating the nature of the site improvements planned, was taken to be 0.7;;eross
the entire site.
The site has been broken up into four (4) areas for drainage analysis purposes. (See Site Plan.)
Run-off from three (3) of these drainage areas, a total of 7.63 acres of the property, is collected
and empties into a proposed underground storm sewer. This pipe will flow into Wolf Pen Creek,
an improved primary channel of the City of College Station's drainage network Surface drainage
generated on the remaining 2.27 acres will "free-flow" off site. By incorporating the underground
storm sewer, the run-off flows to the adjacent property will actually be less than before
development. The majority of the water will bypass surface flow and be collected directly into the
proposed underground conduit entering Wolf Pen Creek approximately 300 feet away.
The computations are as follows: based on the total tributary drainage area of the project being
estimated at 9.90 acres, the pre-development run-off coefficient being assumed at 0.40, and a
minimum time of concentration of 10 minutes, the relative pre-development peak discharge rate
("Q") was determined. The Rational Method was utilized to compute the estimated peak pre-
development discharge rates. The equation that represents the Rational Method is as follows: Q =
CIA. "Q" is the peak discharge rate in cubic feet per second, "C" is the run-off coefficient,
assumed to be 0.40 in the pre-development condition, "I" is the storm intensity in inches per hour,
and "A" is the area of the corresponding basin in acres.
Based on the same tributary area of 9.90 acres, the post-development run-off coefficient being
assumed at 0.75, and a minimum time of concentration of 10 minutes, the relative post-
development peak discharge rate ("Q") was determined using the same minimum time of
concentration of 10 minutes. The Rational Method was again employed to compute the estimated
peak post-development discharge rates. The formula is as follows: Q = CIA, where; "Q" is the
peak discharge rate in cubic feet per second. "C" is the run-off coefficient, in the post-development
condition "C" is assumed to be 0.75, "I" is the storm intensity in inches per hour, and "A" is the
area of the corresponding basin in acres .
The comparison between the peak pre-development discharge rate and post-development discharge
rate is included. Also the corresponding volumes are approximated by simply determining the
volumes generated from the difference of the pre-development and post-development hydrographs .
See the appendix for pre-development and post-development hydrographs. Please note that the
post-development hydrographs show no detention.
Initially, drainage computations are broken down into surface run-off ("free-flow") and the total
flow entering the storm sewer. From the "inflow" rate and time of concentration (10 minutes
minimum), hydrographs were compiled to graphically represent flow concentrations. (See
Appendix.) The hydrographs are triangular in shape and are based on the standard SCS unit
hydrograph with time to peak set equal to the time of concentration and the total time base set at
3.00 times the time of concentration. (Please note that a 30 minute total storm event duration was
utilized exclusively throughout this report.) Tabulations of the pre-development hydrograph and
the post-development hydrograph graphing ordinates are also included in addition to the
hydrographs themselves . (See Appendix.)
The total post-development run-off entering the proposed underground conduit is further broken
down into three sections according to the corresponding sewer inlet. (See attached Site Plan.) A
comparison of pre-development and post-development run-off for each of these sections is
provided. Inlet 1 collects flow from a 3.62 acre section of the site. Inlet 2 and Inlet 3 drain water
off the remaining 1.57 acres and 2.44 acre sections, respectively. Storm sewer inlets and total
pipe diameter are sized according to peak flow rates for the 100-year storm event and are shown in
more detail in the Storm Sewer Capacity Calculations section of this report. The proposed
configuration consists of a 30" R.C.P. running between Inlets 1 & 2 followed by a 36" R.C.P.
between Inlets 2 & 3 and continuing on to the Wolf Pen Creek Channel.
In closing, total post-development peak discharge from the site is less than the pre-development due
to the incorporation of the underground storm facilities. The subsequent peak post-development
surface discharge rates and velocities projected are well within reasonable limits and should not
present any problems downstream. The proposed underground conduit is sized to readily handle
100-year storm peak flow conditions and provide effective transport of the runoff to the Wolf Pen
Creek.

Storm Sewer Capacity Calculations
1.) Determine Inlet Box Size:
Q = CL H3/2 (Wier Equation)
Where,
C = Weir Coefficient = 3.0
H = Drop Height at Opening = 10.0 inches = 0.833 feet
Q = Row Rate (ft3/s)
L = Weir Length (mouth width) = ?
100-Year Storm Peak Row Rates (Q):
Q at Inlet 1 = 31.52 ft3/s (cubic feet per second) ...J Controfs
Q at Inlet 2 = 13.77 ft3/s (cubic feet per second)
Q at Inlet 3 = 21.25 ft3/s (cubic feet per second)
Solve for the length of weir needed,
L = Q/CH3/2
L = 31.52 /(3.0*~
L = 13.81 feet --!JV,quiruf
L = 15 .00 feet --Proviauf (3 ectangular box inlets at 5' width each)
2.) Determine Pipe Size:
Q = ( 1.486/n) AR213Sll2
Where,
n = Manning's Coefficient (for concrete= 0.0013)
R = Hydraulic Radius (ft) -d/4 for round, full pipe
S = Pipe Slope (feet per feet)
Q = Flow Rate (ft3/s)
A = Cross-Sectional Area of Flow (ft2) -IT fll4

fire flows at arbors at wolfpen creek -Reply
Thanks for the "heads up". This is just a suggestion, but perhaps Shirley
Volk could help you on this one from the standpoint of "holding the customer's
hand" in an attempt to get acceptable fire flows. Just a thought.
>>>Veronica Morgan 10/31/95 01:37pm >>>
i recieved these fire flows on this project on friday morning from garrett
engineering. we have reviewed the waterlines plans for this project, twice
now, and since the first review have asked for these flows. Our concern was
that the 6" waterline interior that they were proposing would not be adequate
to serve the complex with fire flows. Unfortunately, we were correct. We now
have a developer who is on an extremely tight time schedule, where we are now
going to have to ask them to reassess their design and propose a solution.
(They need to break ground on November 10, 1995.) I have offered to the
developer a partial ddp -which will let them do tree clearing, grubbing, etc.
but I do not feel comfortable with approving much more than that until we get
this resolved.
To explain their "problem":
Their current design has line velocities during fire flow @18.86 feet/sec
"good design" allows line velocities during fire flows @ 8-10 feet/sec**
we have allowed some developers to go up to 12feet/sec (i.e. circuit city).
**per design criteria -"analysis of water distribution systems by Tom
Walski"
bottom line: i will be calling the engineer and relaying this info to him. i
expect we will hear from the developer on this item.so the intent of this
email is a "heads up"

RE: Availability of Public Water/Wastewater Service
Phase 2, Arbors of Wolf Pen Creek
Adjacent to Northeast Side of Phase 1
Dear Mr. Utley:
According to our best sources, and based on the location drawings we received from your
office, it appears that there are public water and s~tary sewer mains available to the
subject tract. I cannot tell you at this point whether the existing mains are sufficiently
sized for your needs .
Please be aware that it may become necessary for you to extend one or both of these
existing public mains through your property. Should extensions be required, the water
and/or sewer lines must be designed by an engineer according to our standard
specifications.
Call me at 764-3570 if I can be of further help to you.
Sincerely,
Samantha Smith
Engineering Assistant
