EXECUTIVE SUMMARY
This Master Storm Drain Plan (MSDP) is an update to the City of Fontana (City) 1992 City of Fontana and “Sphere of Influence” Master Storm Drain Plan Study (MSDP) prepared by Hall and Foreman (now David Evans and Associates, Inc. (DEA)). This MSDP includes comprehensive analysis of the City’s drainage systems to help identify critical short-term and long-term drainage issues and provides a corresponding list of prioritized capital projects intended to help alleviate them. Prioritized project descriptions, estimated costs, and supporting figures are provided. This report provides the basis for adopting fees to provide funding for design and construction of the capital projects.

Evaluation of the drainage patterns and storm drain recommendations were divided into three separate areas of study to provide a clear level of detail and for planning purposes, which are identified as Area of Study 1 (AOS 1), Area of Study 2 (AOS 2), and Area of Study 3 (AOS 3). Tasks included performing a hydrologic and hydraulic analysis of the City’s storm drain infrastructure. Hydrologic analysis followed the San Bernardino County Hydrology Manual and evaluation of the drainage system hydraulics used the modeling software InfoWorks ICM. Where applicable, existing hydrology studies were used where current and relevant information was provided. An integrated 1- and 2-dimensional (1D/2D) model was developed to represent the storm drain systems in each of the three major study areas listed above. The 1D elements of the model are limited to the master plan of drainage facilities of 36-inch diameter and larger but does not include city or regional detention or recharge facilities. The 2D elements of the model include the surface mesh representing a Digital Elevation Model (DEM) derived ground surface to model overland flow and surface retention storage.

The storm drain system models were used to assess and identify areas of insufficient conveyance capacity and corresponding flooding. To alleviate areas of flooding and insufficient conveyance, proposed ultimate improvements were analyzed with the existing model. The model results with the proposed improvements were then used to determine the conveyance and storm drain capital projects. Development of the capital projects identified a total of 198 projects to address infrastructure needs. The average project cost was $5,925,000, with the minimum being $235,000 and maximum being $87,343,000. In total the cost of AOS 1 is $898,928,000, AOS 2 is $131,702,000, and AOS 3 is $137,433,000.

A set of evaluation criteria was developed to assist in selecting the most critical projects for the City to pursue. The importance of each project was considered using four evaluation criteria: 1. Downstream to Upstream Prioritization 2. Known Flooded Areas 3. Depth of Flooding and 4. Road Hierarchy Drainage.

Capital projects received prioritization scores between 1.0 and 4.4, with 59 projects receiving a score of

2.6 or above, which corresponds to the 30th percentile score. 303

1 INTRODUCTION

1.1 PURPOSE OF THE MASTER PLAN
This Master Storm Drain Plan (MSDP) is an update to the City of Fontana (City) 1992 City of Fontana and “Sphere of Influence” Master Storm Drain Plan Study (MSDP) prepared by Hall and Foreman (now David Evans and Associates, Inc. (DEA)). It is intended to be a user-friendly guidance tool for assessing, planning, and achieving goals for future storm drain management system improvements within Fontana over a 30- to 50-year planning horizon. The target audience is City staff, elected officials, developers, and anyone interested in storm management improvements in Fontana. This MSDP includes comprehensive analysis of the City’s existing and proposed drainage systems to help identify critical short-term and long-term drainage issues and provides a corresponding list of prioritized capital projects intended to help alleviate them.

Prioritized project descriptions, estimated costs, and supporting figures are provided. This report provides the basis for adopting fees to provide funding for design and construction of the capital projects.

Figure 1-1. Current City of Fontana Master Plan, Developed in 1992, Revised in 2006 The City of Fontana and its sphere of influence encompasses approximately 52.4 square miles and is located adjacent to the cities of Rancho Cucamonga, Rialto, Bloomington, and Jurupa Valley in San Bernadino County, California. The Etiwanda and San Sevaine channels run through the westside of Fontana, carrying flows from the Los Angeles mountains to the north and to the Santa Ana River to the south.

Evaluation of the drainage patterns and storm drain recommendations are divided into three separate areas, which are identified as Area of Study 1 (AOS 1), Area of Study 2 (AOS 2), and Area of Study 3 (AOS 3). These areas are primarily tributary to the Etiwanda/San Sevaine Watershed and a small portion 304

1.2 MASTER PLAN OBJECTIVES AND APPROACH
Development of this MSDP and the recommended capital projects started with City and DEA collaborating to determine key goals and objectives for the updated MSDP. This collaborative approach established that the primary focus of this MSDP should be to address storm drain conveyance limitations and localized flooding problems. This MSDP is intended to address and support the goals and objectives listed below, be easy to use, and be easy to update for future revisions.

This updated MSDP has the following objectives:

1. Analyze the City’s existing and future storm drain system capacities to identify potential deficiencies and needed improvements. The improvements considered include:
o Updating hydrology to current NOAA Atlas 14 rainfall data following the County of San Bernardino Hydrology Manual Addendum for Arid Regions dated April 2010 o Incorporate development which has occurred since the 1992 MSDP o Incorporate proposed land use data from the City of Fontana General Plan Land Use Map dated February 2022
o Assess conveyance capacity of primary storm drainage features throughout the City

2. Develop a prioritized list of capital projects that address storm drain system deficiencies (existing and future). The capital projects includes:
o A description of the City’s existing storm drain system o A project prioritization matrix based on key project benefits o A system overview of considered and recommended projects, a City-wide capital projects figure, and a planning-level cost estimate
o A hydraulic model that can be used to assess system responses to improvements and basin changes/developments
o Provide overall cost estimates to assist in creation of development impact fees for drainage infrastructure
Once the objectives were established, the project assessment and analysis began. This step included researching past studies and recommended projects, interviewing City staff about known problems, and performing a hydrologic and hydraulic analysis of the City’s storm drain infrastructure. Evaluation of the drainage system used the modeling software InfoWorks ICM. An integrated 1- and 2-dimensional (1D/2D) model was developed to represent the storm drain systems in each of the three major areas listed above.

The model was limited to drainage facilities of 36-inch diameter and larger. City and regional detention and recharge facilities were not analyzed for capacity as part of this analysis.

The storm drain system models were used to assess and identify areas of insufficient conveyance capacity and corresponding flooding. To alleviate areas of flooding and insufficient conveyance, proposed ultimate improvements were analyzed with the existing model. The model results with the proposed improvements were then used to inform the conveyance and storm drain capital projects. The next step was to prioritize the potential projects based on a matrix of selection criteria established in collaboration between DEA and the City. A total of 198 potential capital projects were identified to address existing capacity limitations and flooding.

1.3 DESIGN CRITERIA
The City’s 1992 MSDP storm management design standards include public and private development requirements, which are intended to provide guidance to design professionals and ensure consistency in the safety and quality of infrastructure improvements that align with conveyance and flood alleviation goals.

The original MSDP design standards will continue to be used with this update.

A summary of the 1992 design standards follows:
• The 100-year design recurrence interval storm was directed by the National Flood Insurance Act of 1968 and the necessity to protect new habitable structures from flooding during the 100-year storm. It was used to size all primary storm lines proposed for the capital projects. • The hydrologic analysis was based on the San Bernardino Hydrology Manual dated January 1986.

The rational method was used to develop unit hydrographs within the Advanced Engineering Software (AES) program. The 1992 MSDP used NOAA Atlas 2 rainfall data, but since that time the City and San Bernardino County have updated to NOAA Atlas 14 rainfall data, which represent an increase of approximately 25%. The updated MSDP uses flows generated from NOAA Atlas 14. See Section 3.1 for more information.
• For the sake of economy, some proposed pipes were limited to convey the 25-year event, where the streets hold the difference in runoff between the 25-year and the 100-year events. Figure 1-3 below shows the design criteria from the 1992 SMPD for these locations. These pipes are generally smaller than 54 inches and located at the upstream ends of proposed projects or along smaller collector lines; larger pipes (typically greater than 54 inches) were sized to convey the 100-year event. See Sections 3.1 and 3.2 for more information.

1.4 PREVIOUS STUDIES AND AVAILABLE DATA
The 1992 MSDP was used as the basis of this study. However, additional studies, specific plans, and other data were also used to prepare this master plan. Table 1-1 lists reports used to provide data and supplementary information to complete this study.

In addition to the studies and reports listed below, as-built plans were used to accurately model existing storm drain infrastructure across the City. Geospatial information (shapefiles) containing existing storm drain pipes and manholes were also used to model existing infrastructure. Additional shapefiles were provided by the City containing information on City streets, pertinent utilities, known flooding locations, land use, and City boundaries.

Three-foot resolution LiDAR derived topography obtained from the City was used in the hydrologic and hydraulic analyses for runoff calculations and facility sizing. Additionally, high resolution aerial photos from 2016 were used to explore, assess, and confirm locations of pertinent drainage features and City infrastructure. All studies, reports, as-built plans, and geospatial information pertaining to City storm drain infrastructure were provided by the City of Fontana.

2 AREA OF STUDY CHARACTERISTICS
This section provides details of the MSDP study area, describing the local climate, topography, soils, existing storm drain infrastructure, and land use conditions used to develop the hydrologic and hydraulic models.

2.1 AREA OF STUDY OVERVIEW
The entire City is located within the Santa Ana River Watershed and ultimately drains to the Santa Ana River. The Fontana watershed lies in the plain adjacent to the Santa Ana River. Generally, the topography of the area is relatively flat, sloping from north to southwest at approximately a 0.5 percent grade. Although, there are portions of the City which drain towards the southeast, located primarily east of Sierra Avenue.

The watershed is predominately urbanized. Storm runoff is generally intercepted by local City facilities then conveyed to major San Bernadino County facilities to the Santa Ana River, then to the Pacific Ocean.

2.1.1 AOS 1
AOS 1 has a drainage area of approximately 20 square miles (sq. mi.; 12,914 ac). The area occupies the middle of the City and is entirely within the City of Fontana (Figure 2-1). AOS 1 is bounded by Interstate 210 (Foothill Freeway) to the north and Interstate 10 to the south. West of Sierra Avenue, AOS 1 drains towards the Etiwanda/San Sevaine Watershed while areas east of Sierra Avenue (between Baseline Road and I-10 Freeway) drain towards the East Fontana Channel following the north side of the Atchison, Topeka and Santa Fe Railroad (ATSF) from Palmetto Avenue to the Rialto Channel. Both areas ultimately drain to the Santa Ana River and into the Pacific Ocean. AOS 1 is fully developed with mixed land uses and contains some of the oldest developments in the City, including the entire Downtown Development area. It is the highest priority for improving storm drainage.

Figure 2-1. AOS 1 Overview

2.1.2 AOS 2
AOS 2 is directly south of AOS 1 and has a drainage area of approximately 14 square miles (9,120 acres).

The area is entirely within the City of Fontana (Figure 2-2). AOS 2 is bounded by Interstate 10 to the north and Philadelphia Avenue, the Jurupa Hills, and the Fontana City Boundary to the south. AOS 2 drains primarily to the Declez Channel, which runs northeast to southwest through the study area. North of the Jurupa Hills, AOS 2 drains southwest, while the Jurupa Hills drain primarily north. The Western-most portions of AOS 2 (generally west of Calabash Avenue) drain towards the San Sevaine Channel. Both channels ultimately drain south to the Santa Ana River and into the Pacific Ocean. The southeast portion of AOS 2, adjacent to the Jurupa Hills drains to the east and into Rialto. The West Valley Logistics Center Specific Plan is proposed in this area but was not considered in this analysis as the specific hydrology and hydraulic analysis for this project is under City review and not finalized for inclusion. AOS 2 has been mostly developed since the 1992 Master Plan was completed and contains mixed land uses. The exception to this occurs near Jurupa Avenue, north of Jurupa Avenue there is significant industrial development and redevelopment opportunities and the area south of Jurupa Avenue and into the Jurupa Hills, remain undeveloped.

2.1.3 AOS 3
AOS 3 is located north of AOS 1 and has a drainage area of approximately 9 square miles (5,691 acres).

The area is entirely within the City of Fontana and drains primarily southwest (Figure 2-3). AOS 3 is bounded by Interstate 210 (Foothill Freeway) to the south and the San Gabriel Mountains to the north. Interstate 15 runs southwest to northeast through AOS 3. Most of AOS 3 north of Interstate 15 drains to the HawkerCrawford Channel. Areas south of Interstate 15 and north of Summit Avenue drain to the Summit Avenue Storm Drain. Areas between Summit Avenue and Interstate 210 drain to the Highland Channel. All areas East of Sierra Avenue drain towards the Cactus Channel, which heads east and south through Rialto. All of AOS 3 ultimately drains to the Santa Ana River and into the Pacific Ocean. AOS 3 is the most recently developed, primarily with residential land uses. Many portions of AOS 3 remain undeveloped, specifically in the northern portion of the study area.

2.1.4 SPHERE OF INFLUENCE
In addition to the City of Fontana boundary, the City also retains a ‘sphere of influence’ boundary, which is an expanded version of the City boundary that includes areas surrounding the City that may be annexed in the future. These areas were also included in the analysis and are shown in Figure 1-2. The majority of the additional area not included in AOS 1, 2, or 3 mentioned previously is located to the West of AOS 1 and includes Kaiser and the Auto Club Speedway (5,092 acres). This area is primarily composed of residential and industrial land use and drains to the San Sevaine Channel. Additional, smaller areas within the sphere of influence that were included in the analysis are located to the southeast of AOS 1 (158 acres), and to the North of AOS 3 in the San Gabriel Mountains (508 acres).

2.2 EXISTING STORM DRAIN INFRASTRUCTURE
The density and adequacy of existing City-owned storm drain infrastructure varies across the City. Since the 1992 MSDP, many developments have been constructed with corresponding storm drain infrastructure that meets capacity requirements. However, other areas are still primarily without subsurface storm drain drainage infrastructure to control local flooding. A summary of existing infrastructure by AOS is provided below. All existing storm drain drainage pipes are shown in Appendix 2. 312
City of Fontana Master Storm Drain Plan
January 25 10

2.2.1 AOS 1
AOS 1 is the oldest and most infrastructure-deficient area of the City. Most of the AOS lacks drainage infrastructure more than park drains and minor (< 36 inches in diameter) storm drainage lines to control localized flooding. The major storm drainage lines (≥ 36 inches in diameter) that do exist are infrequent and primarily centralized in newer parts of the AOS, such as the Village of Heritage and areas north of Baseline Avenue, where portions of the 1992 MSDP were implemented (Figure 2-4).

Figure 2-4. Comparison of Proposed Lines From the 1992 Master Plan to Existing Pipes in AOS 1 (red lines)

2.2.2 AOS 2
AOS 2 has been mostly developed since the 1992 MSDP, and newer residential and industrial developments have sufficient drainage infrastructure. Major storm drain lines, such as the DZ lines, from the 1992 MSDP are present running north to south along most streets between Mulberry Avenue and Sierra Avenue, draining to the Declez Channel (Figure 2-5). Residential developments, including Southridge and Sycamore Hills, also drain via major storm drainage lines to the Declez Channel. Other areas remain undeveloped. 313
City of Fontana Master Storm Drain Plan
January 25 11
Figure 2-5. Comparison of DZ Lines from the 1992 Master Plan to Existing Pipes in AOS 2 (red lines)

2.2.3 AOS 3
AOS 3 is the most recently developed; new residential developments are planned or in construction in several areas. Most of the developed portions of the AOS have sufficient storm drain infrastructure, including the B- and C-lines from the 1992 MSDP (Figure 2-6). Similarly, the Hunter’s Ridge and Coyote Canyon developments contain lines presented in the 1992 MSDP. Undeveloped areas in the northern portions of the AOS have specific plans in place, including the Arboretum development north of Duncan Canyon Road which has major storm lines proposed that are similar to those in the 1992 MSDP. Runoff from areas north of I-15 currently flow through a series of box culverts below I-15 and discharge into an undeveloped area to the south. Drainage patterns for these culverts will be altered based on planned development and are reflected in the present study.

2.3 REGIONAL FLOOD CONTROL CHANNELS
San Bernadino County (County) Department of Public Works operates and maintains several regional flood control channels throughout the City of Fontana. These channels act as the downstream discharge points for major City-owned and maintained storm drain infrastructure. The location and extent of the facilities is shown in Figure 1-2. These include:

Declez Channel – This major facility is a concrete trapezoidal channel that begins at Sierra Avenue, flows west, and drains the majority of AOS 2. It discharges to the Declez Detention Basin before continuing southwest to the San Sevaine Channel. The Chino Basin Groundwater Recharge basins are located along the Declez Channel, near the intersection of Jurupa Avenue and Beech Avenue; however, these basins were not included in the present analysis as they are County facilities and were outside the scope of this study. The Declez Channel was included in the capacity analysis for this study to determine if additional flow to the channel would require upsizing portions of the channel.

I-10 Channel – The I-10 Channel is owned and maintained by Caltrans and flows east to west along the northern side of I-10. It drains the southern portion of AOS 1 before discharging into the San Sevaine Channel. It was included in the capacity analysis to determine if additional flow to the channel would require upsizing portions of the channel.

West Fontana Channel – The West Fontana Channel is a rectangular channel that flows east-towest along the Burlington Northern and Sante Fe Railroad and drains the middle and western portions of AOS 1. It discharges to the San Sevaine Channel after flowing through two regional detention facilities. The analysis calculated the channel capacity through the first detention basin (Banana Basin). 315
City of Fontana Master Storm Drain Plan
January 25 13
Highland Channel – The Highland Channel is a concrete trapezoidal channel that drains AOS 3 between Foothill Freeway and Summit Avenue from Citrus Avenue west. It flows under the Foothill Freeway and into the San Sevaine Channel. It was not included in this analysis because it was determined to be sufficiently sized to convey flows from the contributing watershed based on results of this analysis compared to the design discharge (Q100) for the channel.

East Fontana Channel – The East Fontana Channel is a trapezoidal channel that begins at Mango Avenue and drains east, collecting runoff from eastern AOS 1 between the Burlington Northern and Sante Fe Railroad and Foothills Boulevard. It eventually drains to the Rialto Channel to the east. It was included in the capacity analysis of the current study to determine if additional flow to the channel would require upsizing portions of the channel.

Hawker-Crawford Channel – This channel begins in the north-central portion of AOS 3, north of I15, and flows southwest, collecting runoff from Hunter’s Ridge and Coyote Canyon developments. A reroute of the channel is currently under construction due to the adjacent Nara Hills Development north of I-15. The channel flows into the Rich Detention Basin, then continues and discharges to the San Sevaine Basins. The channel was not included in the present analysis because it is in AOS 3, which is the most recently developed, it is County maintained, and because the area north of the channel that drains into the facility contains new development that was assumed to have sufficiently sized infrastructure.

San Sevaine Channel – The San Sevaine Channel originates in northern AOS 3 at the foot of the San Gabriel Mountains and flows south into the San Sevaine Detention Basins. It then continues south along the western edge of Fontana until it eventually discharges to the Santa Ana River. This channel collects runoff from the majority of the City as it acts as the final discharge point for the other regional channels mentioned above (except the East Fontana Channel). It was not included in the analysis, as it is a County-operated facility, was further downstream from many of the discharge points used in the capacity analysis, and was assumed to be sufficiently sized.

2.4 CLIMATE AND RAINFALL
The City of Fontana climate is characterized as Mediterranean, with hot, dry summers and cool, cloudy winters. Annual rainfall is 14 inches, on average, and rain typically occurs during winter storms between December and March. Snow accumulates in the San Gabriel Mountains to the north of the city that contributes to runoff during the spring freshet. Rainfall typically falls in intense, short duration events, except during more unique events, such as atmospheric rivers that can bring substantial rain over days.

The 1992 MSDP used rainfall data from NOAA Atlas 2 (NOAA, 1973), where rainfall depths and intensities are based on data from fewer rain gauges than updated NOAA Atlas 14 data. The NOAA Atlas 14 Publication (NOAA, 2014) includes data from additional rain gauges that were not available at the time of NOAA Atlas 2, as well as approximately 25 years of additional data from the gauges included in NOAA Atlas 2. The rainfall values from NOAA Atlas 14 were used in this analysis (see Section 3.1 for more information). In general, rainfall intensities based on data from Atlas 14 are 6-10% higher than those from Atlas 2, on average. This analysis used rainfall depths and intensities unique to each AOS, considering the spatial variation in rainfall from north to south Fontana, reflected in the NOAA Atlas 14 data below. 316

25-Year 1.11 1.06 1.22 1.13

2.5 EXISTING LAND USE
Existing land use was based on the 2022 General Plan Land Use Map provided by the City but revised to represent existing conditions. For example, areas that were not currently developed, but are reflected as such in the 2022 general plan, were assigned a land use of ‘Open Space’ for the hydrologic analysis. Areas outside of the general plan boundary, such as those in the San Gabriel Mountains to the north and Jurupa Hills to the south that contribute runoff were also characterized as ‘Open Space’. Land use designations for existing conditions were confirmed via aerial imagery. An exhibit showing the existing land use applied to the hydrologic modeling is shown in Appendix 1.

2.6 PROPOSED LAND USE
Future land use designations were provided by the City as information from the General Plan adopted in 2022. An exhibit showing the future land use applied to the hydrologic modeling is shown in Appendix 1.

A summary of land use for existing and proposed conditions is shown in Table 2-2. A comparison of between impervious percentage used in the 1992 MSDP and this study is provided in Appendix 1. This figure shows an increase in land-use density and corresponding impervious area compared to the 1992 MSDP.

2.7 SOILS
Soils across the City are primarily well-drained, hydrologic group A soils, such as loamy and gravelly sands.

Some areas in mountainous areas to the north and south of the City are less well-drained, hydrologic soil group B, C, and D soils. Soil data was extracted from the USDA Web Soil Survey (USDA, 2023) for the entire sphere of influence. An exhibit showing the soils data applied to the hydrologic modeling is shown in
Figure 2-7. Table 2-3 below summarizes hydrologic soil types in each AOS. Generally, soils in the very northern portion of the City and within the very southern portions of the City are of a finer material and less permeable than the majority of the City which are course and well-draining. 317

3 CAPACITY EVALUATION

3.1 HYDROLOGIC ANALYSIS

3.1.1 TECHNICAL APPROACH
The rational method was used to compute peak runoff rates and develop unit hydrographs to analyze the capacity of existing and proposed storm pipes. Rational method analyses and unit hydrographs were prepared in accordance with the San Bernardino County Flood Control Hydrology Manual. The hydrologic analysis was completed for existing and proposed conditions using updated NOAA 14 rainfall data. The proposed conditions hydrology used land use data from the 2022 General Plan Land Use Map provided by the City. The existing conditions hydrology used the same land use plan but considered areas that have not yet been developed as Open Space.

The hydrologic analysis was divided into two parts. First, hydrology for subbasins draining to existing and proposed storm drain mains/trunklines throughout the City were calculated using the Advanced Engineering Software (AES), Version 2013, for both the 25- and 100-year storms. The second part of the hydrologic analysis included the delineation of additional, smaller subbasins so the proposed storm drain system could be developed with the smallest collector line being at or near a 36-inch pipe diameter. The rational method was used to size the proposed collector lines primarily for the 25-year storm, but also included some collector lines designed for the 100-year storm.

3.1.2 DESIGN STORMS
NOAA Atlas 14 data was used in the analysis. Depths associated with the 5-minute through 24-hour duration were input into AES to produce runoff unit hydrographs. Rainfall data was extracted from the centroid of each area of study. Table 3-1 through Table 3-3 below show the rainfall values used in the analysis.

3.1.3 SUBBASIN DELINEATION
Subbasin delineations for this study used delineations and parcel shapes from the 1992 MSPD study but were updated where necessary to represent current terrain and flow patterns based on updated topographic information. The 1992 MSPD did not include areas that drain towards the East Fontana Channel in Rialto (San Bernardino County Flood Control project area 3-3), so additional delineation was completed in this area based on the Rialto Channel Drainage Area Storm Drain Plan and general drainage patterns of the area. Figure 3-1 shows delineated subbasins for the trunkline hydrologic analysis. Figure 3-2 shows delineated subbasins for each basin used in the collector hydrologic analysis. Figure 3-4 and Figure 3-5 exhibits the M-line portion of AOS 1 used for the collector hydrologic analysis. 321

3.1.4 RUNOFF COEFFICIENTS
Runoff coefficients for each subbasin were computed based on land use and underlying soil conditions, using procedures from sections C.6 and D.5 from the San Bernadino Hydrology Manual. The climate characteristics of the City of Fontana were classified as "valley“.

First, the 24-hour storm runoff yield, 𝑌, was computed for each land use and soil combination (subarea) within each subbasin, based on the curve number and 24-hour rainfall depth:

𝐼𝑎 = 0.2 ∗ 𝑆
𝑆 =
1000
𝐶𝑁 − 10
𝑌𝑗 =
(𝑃24 −𝐼𝑎)
2 (𝑃24 − 𝐼𝑎 +𝑆) ∗ 𝑃24
Where 𝐼𝑎 is the initial rainfall abstraction (in.); 𝑆 is the estimated total soil capacity (in.), 𝐶𝑁 is the subarea curve number listed in Table 3-4 based on land use and soil condition, 𝑌𝑗is the 24-hour storm runoff yield fraction for subarea 𝑗, and 𝑃24 is the 24-hour storm rainfall (in.).

Then, the area-weighted 24-hour storm runoff yield, 𝑌, was computed for each subbasin:

𝑌 =
𝑌1𝐴1 + ⋯ + 𝑌𝑚𝐴𝑚
𝐴1 + ⋯ + 𝐴𝑚
The low loss fraction (portion of runoff lost) was then calculated as:

𝑌̅ = 1− 𝑌
Where 𝑌̅ is the area weighted low loss fraction for each subbasin.

After, the maximum loss rate (in/hr) was computed for each land use and soil combination within each subbasin:

𝐹𝑖 = 𝐴𝑝𝐹𝑝
Where 𝐴𝑝is the pervious area fraction of the subarea (unitless) based on land use (Table 3-4), and 𝐹𝑝 is the infiltration rate (in/hr) based on soil type and antecedent moisture condition (AMC) (Table 3-5).

Then, the area-weighted maximum loss rate, 𝐹 was computed for each subbasin:

𝐹 =
𝐹1𝐴1 + ⋯ + 𝐹𝑚𝐴𝑚
𝐴1 + ⋯ + 𝐴𝑚
For the trunkline analysis, both the low loss fraction and maximum loss rate were then used as inputs to develop unit hydrographs in AES. AMC II was assumed for computations of 𝐹 and Ῡ during the 25-year event and AMC III was assumed for computation of 𝐹 and Ῡ during the 100-year event. Curve numbers were adjusted for AMC III conditions per Table C.1 within the San Bernardina Hydrology Manual. For the 325
City of Fontana Master Storm Drain Plan
January 25 23
trunkline analysis, time of concentrations (TC) were calculated in AES based on landuse, flowpath and/or pipe length, and assumed velocities.

For the collector analysis, a weighted runoff coefficient, 𝐶, was calculated for each subbasin as:

𝐶 = 0.90 ∗ ((1− 𝐴𝑝) +
(𝐼 − 𝐹𝑝) ∗ 𝐴𝑝
𝐼
)
Where 𝐴𝑝 and 𝐹𝑝 are as previously defined, and 𝐼 is the rainfall intensity for a storm duration equal to the subbasin time of concentration. Time of concentration for each basin for the collector analysis was estimated by assuming a velocity along the diagonal flow path across each basin. Average velocities were

0.75, 1.0, and 2.0 ft/s for basins in AOS 1, 2, and 3, respectively, based on the average slope of each AOS.

𝐼 was determined for each subbasin by fitting a power curve to the rainfall intensity-duration curve for events between 5 minutes and 6 hours; an example for AOS 1 is shown in Figure 3-5.

Figure 3-5. Intensity-Duration Curve for AOS 1 to Determine Runoff Coefficients for the Collector Hydrologic Analysis Peak flow rates were then determined for the collector analysis by the rational method equation:

𝑄 = 𝐶 ∗ 𝐼 ∗ 𝐴

3.1.5 UNIT HYDROGRAPH DEVELOPMENT
AES was used to develop runoff unit hydrographs for the trunkline analysis using the resulting times of concentration, loss rates, and low loss fractions described previously. An example of the unit hydrographs generated in AES are shown below in Figure 3-6. Tabular data for all subbasins used in the trunkline analysis are shown in Appendix 1.

3.2 HYDRAULIC ANALYSIS

3.2.1 TECHNICAL APPROACH
A coupled 1- and 2-dimensional (1D/2D) hydraulic model was used to evaluate flooding across the City.

Autodesk InfoWorks ICM was used to perform this analysis. Dynamic modeling allows the effects of storage and backwater in conduits and floodplains and the timing of the hydrographs to yield a more realistic representation of hydraulic conditions. InfoWorks ICM can model the surface using 2D flow, while linking to the storm drain system with a 1D analysis. The result is a comprehensive model that can dynamically communicate between the surface and storm drain. Using these modeling techniques, hydraulic analyses were completed for both baseline (existing storm infrastructure network) and proposed conditions. Figure 3-7 provides a schematic of how a 1D/2D model is configured. The InfoWorks ICM input and results can be found in Appendix 2.

3.2.2 1D MODEL FOR STORM PIPE NETWORK
As-built data and shapefiles showing existing storm drainage pipes and manholes were provided by the City. After a thorough review of the data quality, this information was imported into the InfoWorks ICM model to create 1D elements representing existing pipes and manholes. For AOS 1, existing pipes larger than 18-inches were included in this analysis. AOS 2 and 3 were more recently developed and have fewer capacity issues than older areas of the City, so only the existing pipes 36 inches and larger were included for AOS 2 and 3. All existing pipes incorporated into the ICM model are shown in a large-scale exhibit in Appendix 2.

3.2.3 2D MODEL FOR SURFACE FLOWS
The 2D model domain in InfoWorks ICM relies on topographic data, a computational mesh, and connections to the 1D storm drain model domain. Topography was represented in the model by a 3-foot resolution Digital Elevation Model (DEM) provided by the City. The DEM and associated 50-foot elevation contours are shown in Figure 3-8. All elevations reference the North American Vertical Datum of 1988 (NAVD88). 329
City of Fontana Master Storm Drain Plan
January 25 27
Figure 3-8. City of Fontana Topography
The computational mesh resolution is an important consideration in 2D modeling. Small mesh cell sizes increase accuracy but require additional computation time, while larger mesh sizes compromise accuracy but decrease computation time. Multiple cell sizes can be specified within one model, allowing a larger mesh size to be used in areas where a high level of detail is not required for an accurate model result, such as areas with flat topography. A smaller mesh size should be used in primary areas of interest or where topography changes rapidly. The mesh size specified in this study was intended to replicate the hydraulic behavior of the drainage watershed. It is recommended to have major 2D surface flow paths (such as streets, open channels) to be represented by at least three to four cells. This study used a dynamic 1000- 330
City of Fontana Master Storm Drain Plan
January 25 28
square foot maximum mesh element area size that decreased in size where topography rapidly changes, to a minimum element size of 100-square feet. This mesh size best reflected conveyance within the City and captured enough detail for accurate hydraulic routing to 1D elements. An example of the mesh size resolution is shown in Figure 3-9.

Figure 3-9. Example of 2D Mesh Element Resolution in AOS 3

3.2.4 BOUNDARY CONDITIONS
Hydrographs from the hydrologic analysis were input at discrete 2D points, node locations (manholes), or the upstream end of culverts to capture the accumulation of runoff and resulting flow throughout the City.

Hydrographs were primarily input along trunklines (as shown on Figure 3-1) and as surface flow inputs under existing conditions; proposed condition analyses only included flow inputs along the trunklines.

Modeling ended at the downstream end of trunklines where they either flowed outside the City’s sphere of influence or into County-maintained detention basins or channels. Downstream boundary conditions for these locations were set to outfall with or without considering flow onto the 2D mesh, depending on location. 2D outfall locations were modeled using normal depth as a downstream boundary condition.

3.2.5 MODEL VALIDATION
Model validation was completed by referencing the model results to known flooding locations (Figure 2-8), as this was the only evidence available from the City. Figure 3-10 shows the 100-year storm hydraulic modeling results for existing conditions overlaid with known flooding locations. 331
City of Fontana Master Storm Drain Plan
January 25 29
Flooding history provided in the City Local Hazard Mitigation Plan from 2017 was also used to anecdotally confirm model results. This process provided a level of confidence that the rainfall-runoff relationships in the model sufficiently reflect real world conditions.

Pertinent Information from City of Fontana Flooding History:
• October 19-20, 2004 – “The San Sevaine wash was completely overrun at the Railroad undercrossing just north of Slover Avenue. The resulting flooding waters washed out the train tracks.” During this event, 3 inches fell in 24-hour in nearby San Bernardino (USGS Station 340436117173001); nearly 14 inches fell at the Lytle Creek gauge in the San Gabriel Mountains north of Fontana (USGS Station 341509117312601). These depths are associated with approximately the 25-year event. The San Sevaine channel was not explicitly modeled for this study as it is a County maintained facility, but the areas draining Solver Avenue were. This area experiences flooding greater than 1.25 feet during the 100-year event (Figure 3-11).

Figure 3-11. ICM Model Results Near Slover Avenue During the 100-year Event • December 31, 2004 – “Etiwanda Avenue had to be closed due to flash flooding.” Although the anecdote does not state the area along Etiwanda Avenue that closed, areas along Etiwanda Avenue do experience flooding based on the modeling results, specifically near Jurupa Avenue (Figure 3-12).

3.3 MODEL RESULTS

3.3.1 HYDRAULIC MODEL RESULTS
The existing condition hydraulic results provide a baseline to assess drainage infrastructure deficiency and comparison to proposed drainage improvements. Modeling results indicate that flooding under existing conditions for the 25- and 100-year events is widespread and overwhelms existing infrastructure and streets in many areas, with the worst flooding occurring in AOS 1 and 3. Large portions of both AOS are devoid of drainage infrastructure to handle major storm events. Figure 3-13 to Figure 3-15 show the extent and depth of flooding for the 25-year event under existing conditions for each AOS. The 100-year event is shown in Appendix 2.

General flooding behavior in AOS 1 during the 25-year event is from northeast to the southwest. Much of the flooding from the northern portion of AOS 1 is intercepted by the East and West Fontana Channels.

However, runoff along Sierra Avenue and around the downtown development area continues south as it travels between the East and West Fontana Channels. Runoff in southern AOS 1 collects in the I-10 channel.

The majority of the flooding is less than 0.1 feet; however, many areas experience flooding depths greater than 0.5 feet, such as along Beech Avenue, Valley Boulevard, Oleander Avenue, Catawba Avenue, and Alder Avenue.

In AOS 2, flooding is focused in the west portion of the AOS, where runoff travels primarily south to the Declez Channel. Flooding depths more than 0.5 feet occur along Jurupa Avenue, Cherry Avenue, and Calabash Avenue, as well as other discrete areas near the Declez Channel. Most of the flooding along Jurupa Avenue appears to be linked to flooding along Redwood Avenue and Live Oak Avenue, which are void of storm drain infrastructure.
334
City of Fontana Master Storm Drain Plan
January 25 32
Floods in AOS 3 are primarily conveyed under I-15 from the north through a series of box culverts. These culverts convey runoff from the San Gabriel Mountains. Runoff travels south and west through the AOS, with flooding depths primarily less than 0.1 feet. Few areas experience flooding deeper than 0.5 feet because the existing drainage infrastructure controls surface flooding in the lower portions of the AOS and because runoff from the north travels over undeveloped areas as unconcentrated flow. However, some areas have concentrated runoff reach depths greater than 0.5 feet, such as along Citrus Avenue and Sierra Avenue.

To evaluate flooding results within each AOS, the following indicators were considered to determine the significance of flooding within each area.

3.3.2 CRITICAL FACILITIES
According to the Federal Management Agency (FEMA), the term “critical facilities” is used to describe all manmade structures or other improvements that, because of their function, size, service area, or uniqueness, have the potential to cause serious bodily harm, extensive property damage, or disruption of vital socioeconomic activities if they are destroyed, damaged, or if their functionality is impaired. Critical facilities commonly include all public and private facilities that a community considers essential for the delivery of vital services and for the protection of the community. They usually include:
• emergency response facilities (fire stations, police stations, rescue squads, and emergency operation centers [EOCs])
• custodial facilities (jails and other detention centers, long-term care facilities, hospitals, and other health care facilities)
• schools
• emergency shelters
• utilities (water supply, wastewater treatment facilities, and power) • communications and transportation facilities
• any other assets determined by the community to be of critical importance for the protection of the health and safety of the population
Critical facilities were included in the assessment and protection during a storm event and are shown in Figure 3-16. Table 3-6 and Table 3-7 provides lists of critical facilities that were flooded during the 25- and 100-year event based on the results of the capacity analysis. Data on critical facilities were provided by the San Bernardino County Plan in Geographic Information System (GIS) shapefile format. Tables displaying data for all impacted critical facilities is shown in Appendix 2.

3.3.3 MAXIMUM DEPTH
The hydraulic modeling allows results to be displayed in terms of maximum ponding depth. This is the highest depth at each cell (location) that occurs during a particular storm event. This parameter helps to clearly identify ponded areas where flood depth exceeds existing street curbs or right-of-way. According to the various Emergency Management Handbooks “Deep floodwaters can be dangerous because they can 341
City of Fontana Master Storm Drain Plan
January 25 39
destabilize people and cars, and carry them away, resulting in injuries and fatalities. For instance, 3-feet deep water with no velocity is sufficient to prevent able-bodied adults from wading.” Where maximum ponding depths exceeded 0.5 feet, flood waters travelled over curbs and onto adjacent properties. Figure 3-13, Figure 3-14, and Figure 3-15 show flooding depths for each AOS during the 25- year event. Figures for the 100-year event are in Appendix 2. 25-Year Event
Maximum ponding depths varied between 0 and 11 feet during the 25-year event in AOS 1, with the deepest flooding occurring along Foothills Boulevard where the road dips below the Empire Trail. Average ponding depth in AOS 1 is 0.27 feet; 84% of ponding depths by area are less than 0.5 feet.

In AOS 2, maximum ponding up to 7 feet occurs along the San Sevaine Channel and near Cherry Avenue along the Declez Channel. The average ponding depth in AOS 2 is 0.28 feet; 82% of ponding depths by area are less than 0.5 feet.

In AOS 3, maximum ponding of up to 12 feet occurs within the Sierra Lakes Golf Course. The average ponding depth in AOS 2 is 0.19 feet; 93% of ponding depths by area are less than 0.5 feet. 100-Year Event

In AOS 2, the maximum ponding depth varied between 0 and 8 feet. The average ponding depth in AOS 2 is 0.31 feet; 83% of ponding depths by area are less than 0.5 feet.

Maximum ponding depths varied between 0 and 15 feet in AOS 3. The average ponding depth in AOS 3 is

0.25 feet and 96% of ponding depths by area are less than 0.5 feet.

3.3.4 DURATION OF INUNDATION AND TIME TO INUNDATION
The time to inundation and duration of inundation are important parameters, especially for emergency planning purposes. The time to inundation represents the time it takes to achieve the flooded condition (i.e. depth threshold) at a particular location, while the duration of inundation is the time the flooding (ponding) remains at a particular location. These results allow users to visualize how long it takes to reach certain depths of flooding at critical locations within the City. Effective warning time is the time available for people to undertake appropriate actions, such as elevating or removing belongings and evacuating people and pets. Figure 3-17 to Figure 3-19 display the time to inundation across the City during the 25- year flood. Results for the 100-year event and additional figures showing the duration of inundation are shown in Appendix 2.

4 CAPITAL PROJECTS

4.1 MASTER STORM DRAIN CAPITAL PROJECTS
The development of the storm drain capital projects is intended to provide the City of Fontana with a comprehensive action plan to identify and address storm drain infrastructure issues and propose improvements to effectively manage storm runoff within City limits. Chapter 4 summarizes the process used to identify projects, prioritize these projects, and provide a corresponding cost summary.

The methodology used for identifying proposed projects included researching past studies, known maintenance issues, and performing a hydrologic and hydraulic model analysis of the City’s infrastructure.

The model results were reviewed for areas not meeting the design criteria discussed in section 1.3 and to alleviate flooding. Conveyance solutions were then developed into individual capital projects. Capital projects were spatially divided between major roadways to minimize project impacts during construction, see section 4.2 and 4.3 for additional details. Each project was given a unique indication name based on its location in relation to a prominent trunk line. Generally, this MSDP update attempted to follow the naming convention of the 1992 MSDP where feasible.

Development of the capital projects identified a total of 198 projects to address infrastructure needs. Each project was assessed using a set of weighted criteria to prioritize, with the top 30 percent of projects listed in Section 4.4. Project cost estimating is discussed in Section 4.3.

4.2 CAPITAL IMPROVEMENT PROJECTS

4.2.1 AOS 1
Capital Projects in AOS 1 primarily follow the line names and locations that were laid out in the 1992 MSDP but not yet built, with additional Capital Projects added to minimize flooding and adapt to changing road alignments and development since 1992. In total 135 Capital Projects are proposed in AOS 1. An overview of Capital Projects in AOS 1 is shown as Figure 4-1.

Additional ‘SS’ lines were added throughout the Auto Club Speedway following information from the Auto Club Specific Plan. Similarly, Capital Projects were added in the Westgate area in the northwest corner of AOS 1 following the latest plans available.

The proposed lines T-6 and T-6B along Lime Avenue and across Foothill Boulevard assumes the dip in Foothill Boulevard will be filled, and the Inland Empire Trail will be elevated above Foothill Boulevard. This is currently being addressed by the Margalo Bridge Project which, as of this moment, is a top priority project for the City.

4.2.2 AOS 2
Capital Projects in AOS 2 were also named following the line names and locations that were laid out in the 1992 MSDP. Compared to AOS 1, many of the lines proposed in the 1992 MSDP have already been built, but many smaller lines are still required to minimize flood risk. Lines DZ-4 through DZ-16 are proposed Capital Projects in AOS 2 between I-10 and Jurupa Avenue. An overview of Capital Projects in AOS 2 is shown as Figure 4-2.
346
City of Fontana Master Storm Drain Plan
January 25 44
Some lines required upsizing to convey the 100-year event, such as lines SR-3 and SR-1 in Southridge Village. Additional lines were also added in the southeast corner of AOS 2 to represent development associated with West Valley Logistics Center. In total 30 Capital Projects are proposed in AOS 2.

4.2.3 AOS 3
Capital Projects in AOS 3 were also named following the line names and locations that were laid out in the 1992 MP. Many proposed developments and specific plans provided additional Capital Projects that were incorporated into this master plan. These include lines associated with Ventana and the Arboretum at Fontana (A and B lines). In these cases, pipe sizes determined from other analyses were used to define the Capital Projects. In total 33 Capital Projects are proposed in AOS 3. An overview of Capital Projects in AOS 3 is shown as Figure 4-3.

4.2.4 PROPOSED PROJECTS ON REGIONAL FACILITIES
Hydraulic modeling revealed a need to upsize approximately 330 feet of the East Fontana Storm Drain between Kaiser Avenue and Palmetto Avenue, listed as Capital Project F-0. The existing channel is 5’ x 4’ and the proposed channel is 13’ x 4’ to match the pipe immediately upstream. This project was not estimated for cost or included in the project prioritization analysis but included in the Master Plan Exhibit in Appendix 3 for San Bernadino County consideration.

4.3 CAPITAL PROJECT COST ESTIMATING
Cost estimates were prepared for each of the 198 proposed Capital Projects. The City of Fontana provided a current bid results list (project: DE-24-71-SB, 2024) that was used in conjunction with engineering judgement to determine unit prices for each line item included in the cost estimates. All unit prices are compiled in the Master List of Items (Table 4-2). The unit prices associated with the Master List of Items should only be recognized as average values without strict adherence to specifications and design standards required by the City of Fontana.

Reinforced concrete pipe (RCP) and reinforced concrete box (RCB) unit prices (feet) were determined by taking the average unit prices from the bid results list, excluding the minimum and maximum value, and interpolating for the pipe sizes not included in the provided bid results list using an exponential best fit line (R2=0.99) relating pipe diameter to unit cost. No RCBs were included in the bid results list provided by the City, therefore, the diagonal cross-sectional length of each RCB size was used to determine unit costs, using the same exponential best fit line as for RCPs. Unit prices (feet) for RCP and RCB removal, where upsizing existing pipes was required, were estimated as 10% of the installation unit price of each corresponding pipe and interpolated for the pipe sizes not included in the provided bid results list.

Manhole unit prices were determined by taking the average unit price, excluding the minimum and maximum value. The manhole unit price includes the average bid price for two types of manholes (City of Fontana Standard Detail 3011 and 3012). The number of manholes for each Capital Project were calculated by taking the sum of pipe length (feet) in each project divided by an assumed maximum spacing of 400 feet (City of San Bernardino Storm Drain Design Policy Section 18.44).

Unit prices for saw cutting and removing existing asphalt pavement, replacing asphalt concrete pavement, and crushed miscellaneous base were listed in tons in the bid results list, which were converted to square feet by assuming an asphalt density of 0.0725 ton/feet 3 and a depth of 2 inches. The
crushed miscellaneous base was assumed to be 12 inches, per City of Fontana Standard Detail 1008. The unit prices (feet
2 ) for these items were calculated by taking the average unit price, excluding the minimum and maximum value. Quantities were calculated assuming two feet of additional width was added to the outside diameter of each installed RCP and RCB per City of Fontana Standard Detail 1008.

Additional costs for each Capital Project were included for Traffic Control (5%), Erosion Control (1%), Mobilization and Demobilization (10%), Engineering and Design (10%), Surveying and Staking/Geotechnical (5%), and Construction Management/Staff (10%), based on engineering judgement.

A 20% contingency was assumed for each project for any unforeseen costs. This percentage was increased to 25% for projects that conflicted with major highways, the SCG transmission line, and the 12- foot diameter water main, this increase is noted as contingency + in cost estimates. The cost estimate analysis does not include costs for utility relocation and other miscellaneous items that would be required on a case-by-case basis.

Per the City of Fontana’s direction, the extent of each project was partially dependent on the anticipated cost. A cost estimate for each Capital Project is provided in Appendix 4 and a summary is provided below in Table 4-1.

4.4 CAPITAL PROJECT PRIORITIZATION
A set of evaluation criteria was developed to assist in selecting the most critical projects for the City to pursue. The importance of each project was considered using four evaluation criteria: 1. Downstream to Upstream Prioritization 2. Known Flooded Areas 3. Depth of Flooding and 4. Road Hierarchy Drainage.

All criteria were determined for each project using output from the Infoworks ICM model and information on known flooding locations and road hierarchy provided by the City. Prioritization calculations were completed in ArcGIS Pro, Version 3.10. Each criterion is defined below. 353
City of Fontana Master Storm Drain Plan
January 25 51

4.4.1 PRIORITIZATION CRITERIA
Downstream to Upstream Prioritization
The downstream to upstream prioritization criterion provides a preference to projects that are located on the downstream end of a drainage system. Projects located downstream have the potential of benefiting a greater watershed area as these systems would possibly reduce the tailwater control in the tributary systems. To accurately score systems that act as tributaries to the main stem of a system, the assigned score of the most downstream section of the tributary will be compared to the assigned score of the main stem where the junction occurs. Independent storm drains not tied to a main stem (less than two laterals) will receive a score of no more than 3. Overall, the scores were assigned using engineering judgement.

Table 4-3 shows the criterion scoring. A score of 5 indicates greater priority.

Table 4-3. Downstream to Upstream Prioritization Criteria D/S to Upstream Percent Score
Approximately 65 - 100% 1
Approximately 35 - 65% 3
Approximately < 35% 5
Known Flooded Areas
The known flooded areas criterion accounts for the projects potential to improve flooding in areas that have been documented by the city and residents. Projects adjacent to or that improve drainage in known flooded areas were ranked “5,” and projects away from known flooded areas were ranked “1.” Adjacency of a Capital Project to known flooded areas was limited to a radius of 1,000 feet.

Table 4-4. Known Flooded Areas Prioritization Criteria
Description Score
Project does not contain known flooded areas 1
Project contains known flooded areas 5
Depth of Flooding
The depth of flooding criterion accounts for the projects with the most severe flooding depth based on the 100-year existing conditions model results. Projects with less than 0.5 feet of flooding were ranked “1,” and projects with greater than 1.25 foot of flooding were ranked “5.” For projects located on multiple streets, the most severe flooding depth was used for the ranking.

Table 4-5. Depth of Flooding Prioritization Scoring
Description Score
Flooding Depths less than 0.5 feet 1
Flooding Depths between 0.5 and 0.75 feet 2
Flooding Depths between 0.75 and 1.0 feet 3
Flooding Depths between 1.0 and 1.25 feet 4
Flooding Depths more than 1.25 feet 5
354

January 25 52
Road Hierarchy Drainage Consideration
The road hierarchy drainage criterion accounts for the type of road that a project drains. Priority is given to projects that provide drainage to primary highways and major highways versus collector streets. If a project drains more than one type of road, it will be assigned the score associated with the highest scoring road type in the table below. Corridors within the downtown development area were classified as primary highways for this criterion to increase the rank of projects that drain the downtown development area. An exhibit showing the road hierarchy for the City is provided in Appendix 5.

Table 4-6. Road Hierarchy Drainage Consideration Scoring Road Type Score
Collector Street 1
Major Highway 3
Primary Highway 5

4.4.2 WEIGHTING FACTORS
The four prioritization criteria were given weights corresponding to the relative importance of each criterion and were developed in collaboration with the City. The weights for the four criteria, which add up to 100, are summarized in Table 4-7 below. The weighting system was developed to allow for specific criteria to hold more significance in the final project prioritization score. Once each project was scored on all four criteria, the final project ranking was determined by calculating a weighted score. The assigned weights were multiplied by the corresponding score and each criterion was added to achieve the final score, which ranged between 1 and 5. Projects with higher scores were given greater priority.

Table 4-7. Evaluation Criteria Weighting
Criteria Weight
Downstream to Upstream Prioritization 30
Known Flooded Areas 30
Depth of Flooding 20
Road Hierarchy Drainage 20
Total 100

4.4.3 PRIORITIZATION RESULTS
Projects received prioritization scores between 1.0 and 4.4, with 59 projects receiving a score of 2.6 or above, which corresponds to the 30th percentile score. Table 4-8 and Figure 4-4 below show the results of the prioritization analysis and lists the top 30% highest scoring Capital Projects to improve drainage throughout the City. All prioritization data and results are shown in Appendix 5. Refer to the overall Master Plan exhibit in Appendix 3 for project locations.

Forty-three projects in AOS 1 received a score of 2.6 or greater. These projects are distributed throughout the AOS, but specifically in areas with a history of flooding and along major roadways, such as along Sierra, Fontana, and Beech Avenue. Eight projects in AOS 2 received a score of 2.6 or greater, with most of these projects near the intersection of Beech and Jurupa Avenue, where flooding is known to occur and due to the low position in the drainage network. AOS 3 had eight projects that received a score of 2.6, the maximum of any project in AOS 3. All of these projects are located adjacent to the Highland Channel. 355

5 CONCLUSION AND RECOMMENDATIONS
A key outcome of this study is recommended stormwater infrastructure improvements as part of the 198 capital projects. These projects, once complete, will develop the backbone of the drainage system for the City and will address identified drainage issues. The capital projects should be done in conjunction with the San Bernardino County flood control facilities and other jurisdictional partners where improvements contribute to these systems. Additional improvement may be necessary for localized drainage issue beyond the scope of this study.

It is recommended the City of Fontana implement the following actions:
• Use this information to appropriately set drainage fees to finance the construction of the identified capital projects.
• Reserve and dedicate right-of-way where needed for future project construction. • When development projects file tentative maps or preliminary plans, the City should require as much of the Master Plan facilities to be constructed as possible. 359

Map Unit Descriptions
The map units delineated on the detailed soil maps in a soil survey represent the soils or miscellaneous areas in the survey area. The map unit descriptions, along with the maps, can be used to determine the composition and properties of a unit.

A map unit delineation on a soil map represents an area dominated by one or more major kinds of soil or miscellaneous areas. A map unit is identified and named according to the taxonomic classification of the dominant soils. Within a taxonomic class there are precisely defined limits for the properties of the soils. On the landscape, however, the soils are natural phenomena, and they have the characteristic variability of all natural phenomena. Thus, the range of some observed properties may extend beyond the limits defined for a taxonomic class.

Areas of soils of a single taxonomic class rarely, if ever, can be mapped without including areas of other taxonomic classes. Consequently, every map unit is made up of the soils or miscellaneous areas for which it is named and some minor components that belong to taxonomic classes other than those of the major soils.

Most minor soils have properties similar to those of the dominant soil or soils in the map unit, and thus they do not affect use and management. These are called noncontrasting, or similar, components. They may or may not be mentioned in a particular map unit description. Other minor components, however, have properties and behavioral characteristics divergent enough to affect use or to require different management. These are called contrasting, or dissimilar, components. They generally are in small areas and could not be mapped separately because of the scale used. Some small areas of strongly contrasting soils or miscellaneous areas are identified by a special symbol on the maps. If included in the database for a given area, the contrasting minor components are identified in the map unit descriptions along with some characteristics of each. A few areas of minor components may not have been observed, and consequently they are not mentioned in the descriptions, especially where the pattern was so complex that it was impractical to make enough observations to identify all the soils and miscellaneous areas on the landscape.

The presence of minor components in a map unit in no way diminishes the usefulness or accuracy of the data. The objective of mapping is not to delineate pure taxonomic classes but rather to separate the landscape into landforms or landform segments that have similar use and management requirements. The delineation of such segments on the map provides sufficient information for the development of resource plans. If intensive use of small areas is planned, however, onsite investigation is needed to define and locate the soils and miscellaneous areas.

An identifying symbol precedes the map unit name in the map unit descriptions.

Each description includes general facts about the unit and gives important soil properties and qualities.

Soils that have profiles that are almost alike make up a soil series. Except for differences in texture of the surface layer, all the soils of a series have major horizons that are similar in composition, thickness, and arrangement.

Soils of one series can differ in texture of the surface layer, slope, stoniness, salinity, degree of erosion, and other characteristics that affect their use. On the basis of such differences, a soil series is divided into soil phases. Most of the areas shown on the detailed soil maps are phases of soil series. The name of a soil phase commonly indicates a feature that affects use or management. For example, Alpha silt loam, 0 to 2 percent slopes, is a phase of the Alpha series.

Some map units are made up of two or more major soils or miscellaneous areas.

These map units are complexes, associations, or undifferentiated groups.

A complex consists of two or more soils or miscellaneous areas in such an intricate pattern or in such small areas that they cannot be shown separately on the maps.

The pattern and proportion of the soils or miscellaneous areas are somewhat similar in all areas. Alpha-Beta complex, 0 to 6 percent slopes, is an example.

An association is made up of two or more geographically associated soils or miscellaneous areas that are shown as one unit on the maps. Because of present or anticipated uses of the map units in the survey area, it was not considered practical or necessary to map the soils or miscellaneous areas separately. The pattern and relative proportion of the soils or miscellaneous areas are somewhat similar. Alpha-Beta association, 0 to 2 percent slopes, is an example.

An undifferentiated group is made up of two or more soils or miscellaneous areas that could be mapped individually but are mapped as one unit because similar interpretations can be made for use and management. The pattern and proportion Custom Soil Resource Report

of the soils or miscellaneous areas in a mapped area are not uniform. An area can be made up of only one of the major soils or miscellaneous areas, or it can be made up of all of them. Alpha and Beta soils, 0 to 2 percent slopes, is an example.

Some surveys include miscellaneous areas. Such areas have little or no soil material and support little or no vegetation. Rock outcrop is an example.

Soil Information for All Uses
Soil Properties and Qualities
The Soil Properties and Qualities section includes various soil properties and qualities displayed as thematic maps with a summary table for the soil map units in the selected area of interest. A single value or rating for each map unit is generated by aggregating the interpretive ratings of individual map unit components. This aggregation process is defined for each property or quality.

Soil Qualities and Features
Soil qualities are behavior and performance attributes that are not directly measured, but are inferred from observations of dynamic conditions and from soil properties. Example soil qualities include natural drainage, and frost action. Soil features are attributes that are not directly part of the soil. Example soil features include slope and depth to restrictive layer. These features can greatly impact the use and management of the soil.

Hydrologic Soil Group
Hydrologic soil groups are based on estimates of runoff potential. Soils are assigned to one of four groups according to the rate of water infiltration when the soils are not protected by vegetation, are thoroughly wet, and receive precipitation from long-duration storms.

The soils in the United States are assigned to four groups (A, B, C, and D) and three dual classes (A/D, B/D, and C/D). The groups are defined as follows:

Group A. Soils having a high infiltration rate (low runoff potential) when thoroughly wet. These consist mainly of deep, well drained to excessively drained sands or gravelly sands. These soils have a high rate of water transmission.

Group B. Soils having a moderate infiltration rate when thoroughly wet. These consist chiefly of moderately deep or deep, moderately well drained or well drained soils that have moderately fine texture to moderately coarse texture. These soils have a moderate rate of water transmission.
55 370
Group C. Soils having a slow infiltration rate when thoroughly wet. These consist chiefly of soils having a layer that impedes the downward movement of water or soils of moderately fine texture or fine texture. These soils have a slow rate of water transmission.

Group D. Soils having a very slow infiltration rate (high runoff potential) when thoroughly wet. These consist chiefly of clays that have a high shrink-swell potential, soils that have a high water table, soils that have a claypan or clay layer at or near the surface, and soils that are shallow over nearly impervious material.

These soils have a very slow rate of water transmission.

If a soil is assigned to a dual hydrologic group (A/D, B/D, or C/D), the first letter is for drained areas and the second is for undrained areas. Only the soils that in their natural condition are in group D are assigned to dual classes.
