and signature of the registered professional civil engineer who
prepared them.
2.The subdivider shall pay for the cost of all drainage improvements

A. An enclosed storm sewer shall be provided in all areas where
the quantity of the accumulated storm water runoff does not
exceed two hundred (200) c.f.s.
B. In drainage courses where the accumulated storm water runoff is
more than two hundred (200) c.f.s. and less than five hundred
(500) c.f.s., either an enclosed storm sewer system or a concrete
lined channel shall be constructed
C. In drainage courses where the accumulated storm water runoff is
more than five hundred (500) c.f.s., the drainage improvements
may be either an enclosed storm sewer, a concrete-lined
channel, or an earthen channel. Earthern channels shall be
designed according to the criteria as set fourth herein for open
channel sections.
-24-
3. The design of storm drainage improvements in the City of
Wylie shall be based on flood discharges determined by the
Rational Method. The equation for calculating storm water
flows in this manner is:
Q = CIA, where
"
Q is the storm water flow at a given point, measured in
cubic feet per second;
C is the coefficient equal to the ratio that the peak
rate of runoff bears to the average rate of rainfall;
I is the average intensity of rainfall for a period equal
to the time of flow from the farthest point of the
drainage area to the point of concentration of the storm
flow at the design point.
A is the area, in acres, tributary to the design point.
B. Runoff Coefficient.
The runoff coefficient, which considers the slope of the
terrain, the character of the land-use, the length of over-
land flow, and the imperviousness of the drainage area, shall
be determined from the ultimate land development as shown on
the Comprehensive Plan Report of the City of Wylie. The
minimum runoff coefficient for the appropriate land uses shall
be as follows:
Commercial Areas
Industrial Areas
Residential Areas
"Apa rtment Areas
Park Areas
Churches & Schools
0.90
0.70 -
0.45 -
0.70 -
0.35
0.50
0.90
0.60
0.80

- 0.90
C. Rainfall Intensity - Frequency
The rainfall intensity - frequency curves, which are shown on
Plate 1, are plotted from data published by the U. S. Depart-
ment of Commerce Weather Bureau, Technical Paper No. 40.
The intensity, I, in the formula Q = CIA, is determined from
those curves by arriving at a time of concentration and
adopting a storm frequency upon which to base the drainage
improvements.
1. Time of Concentration
The time of concentration at a design point consists of
the inlet time of the farthest point in the system plus
the flow time from that point to the design point. The
inlet time consists of the overland flow time plus the
gutter flow time required for the storm water to move
from the farthest point contributing to inlet point of
the system.
-25-
A minimum time of concentration of fifteen (15) minutes
shall be used for all areas except commercial areas, and
a minimum time of concentration of ten (10) minutes shall
be used in commercial areas. A nomograph, shown on Plate 2
is attached for estimating the time of concentration.
2. Storm Frequency
The storm drainage improvements in the City of Wylie shall
be designed on the storm frequencies shown in the following
table.
TYPE OF DESCRIPTION OF AREA MAX IMUM TIME OF DESIGN
FACILITY TO BE DRAINED CONCENTRATION FREQUENCY
(Minutes) (Years)
* Storm Sewers Residential, Commercial 30 25
and Industrial
** Culverts, Any type of area less 30 25
Bridges, than 100 acres
Channels &
Creeks
*** Culverts, Any type of area greater 45 25
Bridges, than 100 acres but less
Channels than 1 ,000 acres
and Creeks
Culverts, Bridges Any type of area greater 60 25
Channels & than 1 ,000 acres
Creeks
* When the maximum time of concentration or area to be drained
is exceeded, the design shall be based on a fifty (50) year
frequency.
** When the maximum time of concentration or area to be drained
is exceeded, the design shall be based on a one hundred (100)
year frequency.
***
Whenever, in a storm sewer system, an inlet is located at a
low point so that flow in excess of the storm sewer capacity
would be directed onto private property, the design frequency
shall be increased beyond twenty five (25) years. If the inlet
location is such that overflow could cause damage or serious
inconvenience, it may be desirable to increase the design
frequency to as much as one hundred (100) years.
-26-
D. Area
The area used in determining flows by the "Rational Equation"
shall be calculated by subdividing the map of the development
into drainage areas within the basin contributing storm water
runoff to the system base upon street, alley and ground topo-
graphy.
E. Spred of Water
During the design storm, the quantity of storm water that is
allowed to collect in the streets before being intercepted by
a storm drainage system is referred to as the "spread of water".
In determining the limitations for carrying storm water in the
street, the ultimate development of the street shall be considered.
The use of the street for carrying storm water shall be limited
to the following:
SPREAD OF WATER
Major thoroughfares (divided) - one (1) traffic lane on each
side to remain clear.
Major thoroughfares (not divided) - Two (2) traffic lanes to
remain clear.
Collector streets One (1) traffic lane to remain clear.
Residential streets - Six inch (6") depth of flow at curb,
or no lanes completely clear.
Curves are provided on Plate 3 for determining the spread
of water for certain gutter slopes, gutter discharge, and
pavement crown. Also provided are nomographs for determining
the capacity of gutter flow (Plates 4 and 5) and a curve for
determining the curb inlet opening length (Plate 6).
-27-
F. Storm Sewer Design
Storm water in excess of that allowed to collect in the
streets shall be intercepted in inlets and carried away in
a storm sewer system. Storm sewer capacity shall be calculated
by Manningls Equation--
Q = 1.486 AR2/3 SI/2; where,
n
Q is the discharge in cubic feet per second;
A is the cross-sectional area of flow in square feet;
R is the hydraulic radius in feet;
S is the slope of the hydraulic gradient in feet per
foot; and,
n is the coefficient of roughness (n = .013 for concrete
pipel.
In the design of the storm sewer system the elevation of the
hydraulic gradient of the storm sewer shall be a minimum of
one and one-half feet (1.51) below the elevation of the
adjacent street gutter.
Storm sewer pipe sizes shall be so selected that the average
velocity in the pipe will not exceed fifteen feet (15') per
second nor be less than three feet (3') per second.
Storm sewer pipe shall be reinforced concrete culvert pipe
conforming to ASTM Designation C76 Class III.
G. Open Channel Design
Storm water runoff in excess of that allowed to collect in
the streets in developed areas and runoff in undeveloped
areas may be carried in open channels (not in the streets right-
of-way). Open channel capacity shall be calculated by
Manningls Equation, and roughness coefficients and maximum mean
velocities.

Open Channels shall be constructed with a trapezoidal cross-
section and shall have side slopes no steeper than 4:1 in
earth and 1.5:1 when lined with concrete.
Earth open channels must receive special approval by the
City and must be sodded with Bermuda grass to the satis-
faction of the City.
The subdivider shall dedicate a right-of-way on all earthen
and concrete-lined channels of sufficient width to provide
for excavation of the open channel of proper width, plus ten
foot (101) width on each side to permit ingress and egress for
maintenance, or as required by the City.
H. Culvert Design
At locations of creek crossings with proposed roadway
improvements, it is sometimes necessary to receive and
transport storm water under the roadway in culverts. The
quantity of flow shall be determined by the Rational Method
and the capacity of the culvert shall be calculated by
Manning's Equation.
Design of culverts shall include the determination of
upstream backwater conditions as well as downstream
velocities and flooding conditions. Consideration shall be
given to the discharge velocity from culverts, and the
following limitations are allowed.

Generally, all culverts shall be designed with a free
outfall, and the following head losses shall govern the
design of the culvert.
-29-
1. Frictional Head Loss
h f = S f L, Where
S f = Slope of hydraulic gradient in feet per foot; and
L = Length of culvert in feet.
2. Head Loss Due to Change in Velocity
h v = V 2 2 - V 1 2, where,
V 2 = Velocity in culvert;
V 1 = Velocity in channel above culvert; and,
g = Acceleration due to gravity.
3. Head Loss at Upstream Entrance to Culvert Due to Entrance
