EXISTING CAPACITY STUDY
HAWKER CRAWFORD CHANNEL
COYOTE CANYON SPECIFIC PLAN - FONTANA, CALIFORNIA
1. PURPOSE OF STUDY
Coyote Canyon LLC seeks the approval from the City of Fontana for the existing capacity study for
the reach of the Hawker Crawford Channel located within the Coyote Canyon Specific Plan,
specifically adjacent to TTM No. 16326, TTM No. 16325-1, and TrM No. 16325-2. The purpose
of the study is to determine if the existing unimproved Hawker Crawford Channel has adequate
capacity to convey the tributary 100 -year flows within the study reach.
11. PROJECT SITE AND DRAINAGE AREA OVERVIEW
The Coyote Canyon Specific Plan is located in the City of Fontana, County of San Bernardino, and
State of California. This 323 -acre project site is roughly bounded by 1-15/Duncan Canyon Road to
the south and east, the existing Hunter's Ridge development to the west, and the undeveloped
hillsides to the north (see Figure 1). TTM No. 16326, TTM No. 16325-1, and TTM No. 16325-2
are located within the southern portion the Coyote Canyon Development, south and south east of
Rich Basin, respectively (see Exhibit "E").
The Hawker -Crawford Channel is the existing major watercourse that impacts the proposed
tentative tract maps. The Hawker -Crawford channel enters the project site from the northeast
project boundary and traverses the site southwesterly before discharging into the Rich Detention
Basin. The outlet channel for the Rich Detention Basin continues downstream and joins the San
Sevaine Drainage system.
The Hawker Crawford Channel poses a possible flooding threat to the proposed tentative tract
maps previously mentioned. The ultimate facility improvements will alleviate the possible
flooding i ssue, b ut t hey m ay not be constructed until some time after the development of the
proposed tentative tract maps. Therefore, this study analyzes the Hawker Crawford Channel in
its existing condition to determine the existing 100 -year floodplain limits.
111. FLOOD PLAIN ANALYSES
The analysis for the Hawker -Crawford Channel was performed with the Boss River Modeling
System (RMS) HEC -RAS Module, and the United States Army Corps of Engineers "HEC -RAS
3.0" software. The RMS program allows a river model to be analyzed within an Autocad
environment. The project topographic map was used to develop the cross sections (see Exhibit
"D"). Analysis summary tables are included herein along with the input and output files. Prior to
beginning the analysis for the Hawker -Crawford Channel, the hydraulic parameters for the stream
were determined. The following is a list of parameters utilized to analyze the Hawker Crawford
Channel:
Per the Coyote Canyon Master Drainage Plan (Reference 1), the Hawker -Crawford flow
rate to be used for this study is 2,830 fels. This flow represents a "Bulked" 100 -year
storm event condition. A bulking factor of 1.5 was used.

2) The existing HEC -RAS model used the following Manning's "n" value:
Zone Description
Manning 'In" value
Surface
Channel
0.027
Earthen gravel channel
North Overbank
0.032
Tilled soil with patches of
vegetation
South Overbank
0.032
Tilled soil with patches of
vegetation
3) Starting water surface elevations for the subcritical model is based on critical depth.
4) For the most part, the sides of the main channel are protected with small cobbles and
rocks. The banks extend above the adjacent ground, thus forming a levee condition.
Since the south and north channel levees are not FEMA certified levees, the potential for
levee failure exists. In an effort to model the worse case flood plain limits for the
existing Hawker -Crawford Channel, a flood plain analysis was performed based upon the
assumption that both the existing north and south levees will fail.
5) Two (2) culvert crossing, located approximately 200' south of Coyote Canyon Road and
480' north of Coyote Canyon Road, exist along the study reach of the Hawker Crawford
Channel. These crossings are composed of a depressed or "sag" roadway across the
channel with triple -36" corrugated metal pipes (CMP) culverts for low flows (see project
photographs). The triple 36" CMP culverts were modeled with approximately 6 -inches
of debris deposited in each pipe.
IV. FINDINGS
The results of the existing flood plain analysis for the Hawker -Crawford Channel indicate that if
the e xisting I evees f ail, t he n orth a nd s outh o verbanks o f t he H awker C rawford Channel will
become inundated. These flows will overtop the existing Coyote Canyon Road and proceed
southwesterly through the project site. The overbank flooding will consist of shallow flooding
typically one foot or less in depth. The shallow flooding within the south overbank will reenter
the Hawker Crawford Channel before it discharges into the existing Rich Basin. The proposed
pad elevations adjacent to Rich Basin and the Hawker Crawford Channel will be elevated a
minimum of one foot above the existing base flood elevation (see Exhibits "B" and "B- I").
In summary, the detailed study shows that the existing Hawker Crawford Channel will convey
the 100 -year storm flows with the associated floodplain. The proposed TTM No. 16325-1 and
TTM No.16326 will remain outside of the 100 -year flood hazard while portions of TTM No.
16325-2 will remain within the flood plain area (see Exhibit "B" and "B -l"). Only those areas of
TTM No. 16325-2 that are located outside of the 100 -year flood plain can be developed prior to

Warning: The energy equation could not be balanced within the specified number of iterations. The
program used critical depth for the water surface and continued on with the calculations.
Warning: The conveyance ratio (upstream conveyance divided by downstream conveyance) is less
than 0.7 or greater than 1.4. This may indicate the need for additional cross sections.
Warning: The energy loss was greater than 1.0 ft (0.3 m). between the current and previous cross
section. This may indicate the need for additional cross sections.
Warning: During the standard step iterations, when the assumed water surface was set equal to
critical depth, the calculated water surface came back below critical depth. This
indicates
that there is not a valid subcritical answer. The program defaulted to critical depth.

warning: The energy equation could not be balanced within the specified number of iterations. The
program used critical depth for the water surface and continued on with the calculations.
Warning: The energy loss was greater than 1.0 ft (0.3 m). between the current and previous cross
section. This may indicate the need for additional cross sections.
Warning: During the standard step iterations, when the assumed water surface was set equal to
critical depth, the calculated water surface came back below critical depth. This
indicates
that there is not a valid subcritical answer. The program defaulted to critical depth.
warning: The parabolic search method failed to converge on critical depth. The program will try the

Warning: The energy equation could not be balanced within the specified number of iterations. The
program used critical depth for the water surface and continued on with the calculations.
Warning: The velocity head has changed by more than 0.5 ft (0.15 m). This may indicate the need for
additional cross sections.
Warning: The conveyance ratio (upstream conveyance divided by downstream conveyance) is less
than 0.7 or greater than 1.4. This may indicate the need for additional cross sections.
Warning: The energy loss was greater than 1.0 ft (0.3 m). between the current and previous cross
section. This may indicate the need for additional cross sections.
warning: During the standard step iterations, when the assumed water surface was set equal to
critical depth, the calculated water surface came back below critical depth. This
indicates
that there is not a valid subcritical answer. The program defaulted to critical depth.
Warning: The parabolic search method failed to converge on critical depth. The program will try the
cross section slice/secant method to find critical depth.
Note: multiple critical depths were found at this location. The critical depth with the lowest,
valid,
water surface was used.

warning: The energy equation could not be balanced within the specified number of iterations. The
program used critical depth for the water surface and continued on with the calculations.
Warning: The cross-section end points had to be extended vertically for the computed water surface.
Warning: The energy loss was greater than 1.0 ft (0.3 m). between the current and previous cross
section. This may indicate the need for additional cross sections.
Warning: During the standard step iterations, when the assumed water surface was set equal to
critical depth, the calculated water surface came back below critical depth. This
indicates
that there is not a valid subcritical answer. The program defaulted to critical depth.
Note: Multiple critical depths were found at this location. The critical depth with the lowest,
valid,
energy was used.

warning: The energy equation could not be balanced within the specified number of iterations. The
program used critical depth for the water surface and continued on with the calculations.
Warning: Divided flow computed for this cross-section.
Warning: The velocity head has changed by more than 0.5 ft (0.15 m). This may indicate the need for
additional cross sections.
Warning: The conveyance ratio (upstream conveyance divided by downstream conveyance) is less
than 0.7 or greater than 1.4. This may indicate the need for additional -cross sections.
Warning: The energy loss was greater than 1.0 ft (0.3 m). between the current and previous cross
section. This may indicate the need for additional cross sections.
Warning: During the standard step iterations, when the assumed water surface was set equal to
critical depth, the calculated water surface came back below critical depth. This
indicates
that there is not a valid subcritical answer. The program defaulted to critical depth.
Note: Multiple critical depths were found at this location. The critical depth with the lowest,
valid,
energy was used.

Warning: The energy equation could not be balanced within the specified number of iterations. The
program used critical depth for the water surface and continued on with the calculations.
Warning: The energy loss was greater than 1.0 ft (0.3 m). between the current and previous cross
section. This may indicate the need for additional cross sections.
Warning: During the standard step iterations, when the assumed water surface was set equal to
19
critical depth, the calculated water surface came back below critical depth. This
indicates
that there is not a valid subcritical answer. The program defaulted to critical depth.

warning: The energy equation could not be balanced within the specified number of iterations. The
program used critical depth for the water surface and continued on with the calculations.
warning: The cross-section end points had to be extended vertically for the computed water surface.
warning; The energy loss was greater than 1.0 ft (0.3 m). between the current and previous cross
section. This may indicate the need for additional cross sections.
Warning: During the standard step iterations, when the assumed water surface was set equal to
critical depth, the calculated water surface came back below critical depth. This
indicates
that there is not a valid subcritical answer. The program defaulted to critical depth.
Warning: The parabolic search method failed to converge on critical depth. The program will try the
cross section slice/secant method to find critical depth.

warning: The energy equation could not be balanced within the specified number of iterations. The
program used critical depth for the water surface and continued on with the calculations.
Warning: The energy loss was greater than 1.0 ft (0.3 m). between the current and previous cross
section. This may indicate the need for additional cross sections.
Warning: During the standard step iterations, when the assumed water surface was set equal to
critical depth, the calculated water surface came back below critical depth. This
indicates
that there is not a valid subcritical answer. The program defaulted to critical depth.

Warning: The energy equation could not be balanced within the specified number of iterations. The
program used critical depth for the water surface and continued on with the calculations.
warning: The cross-section end points had to be extended vertically for the computed water surface.
Warning: The velocity head has changed by more than 0.5 ft (0.15 m). This may indicate the need for
additional cross sections.
Warning: The energy loss was greater than 1.0 ft (0.3 m). between the current and previous cross
section. This may indicate the need for additional cross sections.
Warning: During the standard step iterations, when the assumed water surface was set equal to
critical depth, the calculated water surface came back below critical depth. This
indicates
that there is not a valid subcritical answer. The program defaulted to critical depth.
Warning: The parabolic search method failed to converge on critical depth. The program will try the
cross section slice/secant method to find critical depth.
