EXECUTIVE SUMMARY
The proposed California Speedway project is located on approximately 600 acres of the former
Kaiser Steel Mill. The storm runoff from this site is tributary to the San Sevaine Channel which is
located along the west edge of the site. A Master Plan of Drainage report prepared for the City
of Fontana proposed an east -west lateral be located at approximately the southern boundary of
this site.
The San Sevaine Channel is presently unimproved and therefore we will detain storm runoff
on -site until the channel is improved. For the interim condition, detention basins will be located in
the southwest corner of the site and will be designed to San Bernardino County Detention Basin
Design Criteria. One of the basins will also be used for parking. All three drainage systems outlet
into the basin / parking area. For the ultimate design situation, all three drainage systems outlet
into the same parking area, but flows are conveyed through the parking area in open channels
until they reach the southwest corner of the area and enter a pipe outletting into the San Sevaine
Channel.
The drainage systems will utilize a combination of open channels, box culverts, pipes and roadway
culverts. The infield area of the race track will also include a fuel / oil separation system to treat
the "first flush" from the garage and pit areas. All basins and drainage systems will be privately
owned and maintained.
Both unit hydrograph and rational method hydrology reports are included as backup for the
� r design of the drainage systems and detention basins. The proposed land use was "commercial"
and "urban cover ". Both are 5% pervious. Some of the parking areas may be grass or gravel, but
the conservative assumption was made that all areas would be considered 5% pervious.
Preliminary sizes and locations for drainage facilities can be determined from the storm runoff
quantities provided in this report.

O: JOB -NO` 1 1)94 40,4MIPRO\DRREP SAKI 2 /d95
The purpose of this report is to determine storm drain runoff quantities that can be used to size
and locate storm drain facilities on the California Speedway site. These quantities are based on
hydrology and hydraulic calculations provided herein.
The project site is located on an alluvial fan which slopes at a grade of approximately one percent
(1%) to the southwest. The drainage area is approximately 600 acres of the abandoned portion of
the former Kaiser Steel Mill. Currently, the site consists of abandoned building and foundations,
open land, and debris from the demolition of steel mill related structures.
The site is bounded on the north by the West Fontana Channel and the AT &SF Railroad tracks,
on the south side by the California Steel Industries. To the west is the San Sevaine Channel and
to the east is Cherry Avenue.
Presently storm runoff runs through the site and onto the California Steel Industries (CSI) site to
the south. There are some existing drainage structures on -site which convey a small portion of
the storm runoff either to the San Sevaine Channel or onto the CSI site. The degradation of the
existing underground drainage facilities, their complex alignments and connections, their
inconsistent size and type, and the lack of plans or design data prohibits the reliable use of these
facilities.
The West Fontana Channel located on the north side of the AT & SF Railroad tracks provides
protection from storm runoff from the north. The West Fontana Channel conveys runoff westerly
to the Banana Basin then continues west, crosses under the railroad tracks and into Hickory Basin
before finally entering the San Sevaine Channel. The San Sevaine Channel is an unlined and
unimproved channel which flows from north to south. This channel protects the west edge of the
site from runoff and it is the outlet for the on -site drainage system. Storm flows from the east are
conveyed southerly by Cherry Avenue.
On -site soil is categorized as Soil Group A per the San Bernardino County Flood Control District
(SBCFCD) Hydrologic Soils Group Map.

Standard hydrology calculation procedures were followed per the 1986 County of San Bernardino
Hydrology Manual. Computer software by Advanced Engineering Software (AES) was utilized
for hydrology calculations.
RATIONAL METHOD
The rational method was used for sizing the storm drain system as well as for establishing a
time of concentration for the unit hydrograph calculations.
UNIT HYDROGRAPH METHOD
The interim drainage system will include a detention basin, therefore the unit hydrograph
method was used for a comparison of the proposed condition to the existing condition.
Maximum volumes and peak flows were calculated and compared for 2, 10, 25, and 100 year
events. The criteria outlined in the SBCFCD memo dated September 4, 1987 was followed
for determining allowable peak outflow from the detention basin.
LAND USE
Existing land use was determined to be 'Barren" and 100% pervious in accordance with land
use classifications used in San Bernardino County Hydrology Manual. See "Appendix A -
,; Existing Condition" for the calculation of values used for the unit hydrograph calculations.
Proposed development was divided into two land use types - "Commercial" and "Urban
Cover," both 5% pervious. The unpaved parking areas are designated "Commercial" due to
the possibility that the areas could be paved in the future. See Appendix A for the calculation
of values used for the unit hydrograph calculations.
ANTECEDENT MOISTURE CONDITION (AMC)
AMC III was used in existing condition calculations. AMC III was used for proposed
condition calculations due to the use of detention basins.

PYROM O Wel o_ raw
The San Sevaine Channel is the ultimate outfall for on -site drainage. For the design of the
interim drainage system, the channel will be left unimproved as it exists today with the
exception of where project site outflows enter the channel. The existing channel is
approximately 15 feet deep with a dirt bottom and rubble sides.
The ultimate channel design is based on a preliminary study prepared by Bill Mann and
Associates for the San Bernardino County Flood Control District. The plans (sheet 10 of 34)
proposes a trapezoidal channel with a slope of 1.36 %. The channel dimensions are shown on
Exhibit B.
The design Q used to determine the water surface in the San Sevaine Channel is a preliminary
number given to us be the San Bernardino County Flood Control District. The Q 100 used is
17,740 cfs. This number is considered conservative and is expected to be reduced due to
incorporating basins in the master area drainage system upstream of the California Speedway
site.
BASIN DESIGN CRITERIA
• Detention basins will follow SBCFCD Detention Basin Design criteria with the
exception that the maximum water depth may be greater than 6 feet, but no more than
13 feet.
• Basins A and B will be in- ground basins (no berms) to avoid being considered for
State jurisdiction as a dam.
In the interim design, two detention basins will be required, Basin A and Basin B (See Exhibit
A).
Basin B is a temporary basin which can be removed after the San Sevaine Channel is
improved. It is an in- ground basin with no detained water above adjacent ground. Wet
slopes will be sloped at a maximum of 3:1. The ponded storm water outlets from Basin B to
the San Sevaine Channel. The basin will have a controlled outlet rate of 90% of the existing
condition peak flow rate. A paved emergency spillway is located along the west edge of this
basin and outflows directly into the San Sevaine Channel. Basin B will be connected to Basin
A with a 114" pipe.
Basin A will serve as the secondary basin in the interim design. It will be a joint use basin in
that it will serve as a parking area during periods of no rainfall. The basin portion of the
parking area will be fenced off so that the area can be closed when used to detain storm
runoff. This basin will be filled by the drainage system from the east and a drainage system
from the northeast. Storm runoff flows will be conveyed through the basin along the south
edge of the basin at a minimum slope of 0.5 %. Flows from the northeast will be conveyed
along the west edge of the basin.
OU OB- NO \IQ94\ 40\AMIPRO \DRREP.SAM 216/95 4
Below is a table summarizing the hydraulic conditions in the basins for the indicated storm
events. In all cases, the design outflow from the basins is less than the allowable outflow.
The allowable outflow was determined in accordance with the SBCFCD memo dated
September 4, 1987, which establishes the criteria based on 90% of the peak flows from the
storm events with revised intensities.
BASINS A & B
PROPOSED CONDITION
In the ultimate design, Basin B can be filled in and replaced with pipe to connect the inlet in
the parking area (interim Basin A) with the outlet to the San Sevaine Channel (See Exhibit
B).
Ank Interim Basin A will no longer be needed as a detention basin. Storm runoff can be conveyed
through the parking area along the west and south sides by open channels. The parking area
can then be filled in to raise elevations to allow surface flows to be intercepted by the open
channels.
BASIN MAINTENANCE
Until the San Sevaine Channel is improved, Basins A and B will be required to detain storm
runoff. Basin B will be fenced to prevent access of unauthorized persons. Basin A will be a
joint use basin, serving also as a parking area. This basin will be fenced along the top of
slope on the south and west sides. A fence will also be necessary at a location above the limit
of ponded depth for the 100 -year event. This fence will have a 20 foot wide gate for access
into the parking area. No parking will be allowed within the basin area if rain is predicted
within 24 hours. Access to Basin A area will be restricted whenever water is ponded in the
basin area or during rain storms.
The basins and the storm drain system will be privately owned and maintained.

STORM DRAIN DESIGN CRITERIA
Underground storm drain system designed to convey 10 -year storm.
• On -site channels designed to convey 100 -year storm.
• 100 -year storm conveyed to San Sevaine Channel by underground storm drain system.
• For the 100 -year storm, the water surface will be a minimum of 1 foot below the
finished floor of any occupied building.
SOUTHERN DRAINAGE SYSTEM
This system conveys drainage from the east side and south side of the race track into the
Basin A / parking area.
This system begins at a headwall on the north side of the western access road and at the east
end of the Basin A area. The system continues below ground under the access road to the
south and east until it becomes an open channel along the south property line. This channel
follows the property line easterly turning to the northeast to follow the access road near the
east edge of the site. This channel will be designed to allow overland flows from the parking
area to flow over the access road and directly into the channel. A pipe continues north to
collect runoff from the area along the east side of the site. The storm drain system will
terminate just south of the MAID transmission line to avoid crossing the MAID facilities.
The drainage system along the east side of the race track will convey the Q 10 runoff in the
roadway until the water level exceeds the top of curb. Q 10 runoff will then be intercepted
and put into an underground system. The difference between Q 100 and Q 10 runoff will be
carried on the surface until it reaches the open channel along the south property line. This
channel will intercept and convey Q100 to the west, ultimately reaching the San Sevaine
Channel through the drainage system described above.
INFIELD DRAINAGE SYSTEM
The Infield Drainage System conveys storm runoff from the race track infield southwesterly
to outlet into the Basin A / parking area. The tunnel under the race track will be graded to
drain runoff away from the infield area should the drainage system not function.
The "first flush" storm runoff from the pit area and garage area will be intercepted and treated
by a fuel / oil separation system before the water is released to the storm drain system.
a
O'iJOB -NO�1 ° 40'AMIPR0',DRREP.SAM 2;0.05 6
The underground drainage system will carry the runoff from the Q10 storm. The difference
between the Q 100 and the Q 10 runoff will be conveyed as surface flow away from the infield
�rrr area through the tunnel.
NORTHERN DRAINAGE SYSTEM
The Northern Drainage System drains the areas north and west of the race track. The
drainage system will be a combination of open channels and culverts outletting into the Basin
A / parking area.
The open channel system will convey the runoff from a Q 100 storm to the Basin A / parking
area. Culverts under roadways will carry small storm flows with larger flows crossing the
roadway at a low point near the culvert.

Notes:
1. Land use should be based on ultimate development of the watershed. Long
range master plans for the County and incorporated cities should be reviewed
to insure reasonable land use assumptions.
2. Recommended values are based on average conditions which may not apply to
a particular study area. The percentage impervious may vary greatly even on
comparable sized lots due to differences in dwelling size improvements, etc.
Landscape practices should also be considered as it is common in some areas
to use ornamental gravels underlain by impervious plastic materials In place of
lawns and shrubs. A field investigation of a study area shall always be made,
and a review of aerial photos, where available, may assist in estimating the
percentage of impervious cover in developed areas.
3. For typical equestrian subdivisions increase impervious area S percent over the
values recommended in the table above.

C.6. ESTIMATION OF LOSS RATES
In estimating loss rates for design hydrology, a watershed curve number
(CN) is determined for each soil -cover complex within the watershed using
Figure C -3. The working range of CN values is between 0 and 98, where a
low CN indicates low runoff potential (high infiltration), and a high CN
indicates high runoff potential (low infiltration). Selection of a CN takes into
account the major factors affecting loss rates on pervious surfaces including
the hydrologic soil group, cover type and quality, and antecedent moisture
condition (AMC).
Also included in the CN selection are the effects of "initial abstraction" (Ia)
which represents the combined effects of other effective rainfall losses
including depression storage, vegetation interception, evaporation, and trans-
piration, among other factors.
