Sensitive Receptors: There are individuals deemed sensitive receptors due to their fragile immune systems and special sensitivity to environmental discharges. These sensitive receptors typically include the elderly, the sick, and children. While the location of all sensitive receptors cannot be determined, EDR indicates those buildings and facilities - schools, daycares, hospitals, medical centers, and nursing homes - where individuals who are sensitive receptors are likely to be located.

Tract No. 20245 is located in the City of Upland, in San Bernardino County, California. Tract No. 20245 will consist of residential housing and a park area. Tract No. 20245 boundary encompasses approximately 9.2 acres. The proposed development will build 65 single family detached dwellings, streets and underground utilities within the site.

Tract No. 20245 will be built over a portion of the existing 15th Street Basin. A portion of the 15th Street Basin will be regraded and used to build the proposed residential development. Impacts to the existing 15th Street Basin are analyzed in a separately submitted drainage report prepared by Madole & Associates, dated June 12, 2017.

Onsite runoff from Tract No. 20245 will be collected and conveyed by a proposed onsite storm drain system. The onsite runoff will be collected by grated inlets within each lot and two curb inlets and conveyed to the proposed 12’ x 8’ RCB.

There are approximately 6.8 acres of landscape areas that currently sheet flow toward the 15th Street Basin. Once Tract No. 20245 is developed, runoff from these landscape areas will be conveyed by separate storm drain lines system and discharged to the 15th Street Basin. These existing landscape areas are identified in Exhibit A as drainage areas, Area A, Area B and Area c19.

1.2 Project Objectives
The objectives of this study include the following:

1. Prepare a hydrologic analysis of the developed condition based on land uses, drainage patterns, ground slopes, and soil types to generate the 100-year and 50-year flood storm events. The hydrology computations are based on the San Bernardino County Hydrology Manual.

2. Determine final storm flow rates through the project site and identify the required storm drain conveyance facilities to develop Tract No. 20245.

1.3 Existing Facilities
The Tract No. 20245 project site is currently used as a detention basin facility. There are several storm drain facilities within Tract No. 20245 that are currently serving the 15Th Street Basin.

There is an existing 84” RCP storm drain that conveys runoff to the northwest corner of 15th Street Basin. There is an existing 48” RCP storm drain located 280’ east of the Tract No. 20245 boundary. that outlets to the 15th Street Basin. A concrete gutter located approximately 70’ west of the Tract No. 20245 boundary conveys runoff to the 15th Street Basin. A 102” RCP storm drain is used to dewater the 15th Street Basin. This 102” RCP storm drain inlet is located approximately 200’ northwest of the Fernando Avenue and 15Th Street intersection.

1.4 Proposed Facilities
A section of the existing 84” RCP storm drain line will be removed. A proposed 12’ x 8’ RCB storm drain will extend the 84” RCP storm drain easterly along southern Tract No. 20245 boundary. The proposed 12’ x 8’ RCB alignment will outlet east of Tract No. 20245 and onto the 15th Street Basin.

A section of the existing 102” RCP storm drain will be removed. A proposed 102” RCP storm drain will extend the existing 102” RCP storm drain easterly along southern Tract No. 20245 boundary. The proposed 102” RCP storm drain will parallel the proposed 12’ x 8’ RCB storm drain. The proposed 102” RCP storm drain will be used to dewater the 15th Street Basin.

A proposed 30” RCP storm drain line will convey runoff from an existing 48” RCP storm drain and flows from Area A. This proposed 30” RCP storm drain line is located 260’ east of the western Tract No. 20245 boundary. The 30” RCP storm drain will connect to the proposed 12’ x 8’ RCB storm drain.

A proposed 30” RCP storm drain line will convey runoff from an existing concrete gutter located near the northeast corner of Tract No. 20245 and flows from Area B. This proposed 30” RCP storm drain line is located 70’ west of the eastern Tract No. 20245 boundary. The 30” RCP storm drain will connect to the proposed 12’ x 8’ RCB storm drain.

Peak flow rates for the 12’ x 8’ RCB, 102” RCP, and two 30” RCP storm drains are provided in a separately submitted drainage report.

A proposed onsite storm drain system will be located within Tract No. 20245. The onsite system will consist of grated inlets, curb inlets, PVC and RCP pipes. The proposed storm drain layout is provided in Exhibit A, see Appendix A.

1.5 Flood Assessment
The Federal Emergency Management Agent (FEMA) publishes Flood, Insurance Rate Maps (FIRMs) that identify areas where there is flooding potential. The FIRM that applies to Tract No. 20245 is San Bernardino County Panel 8607 (Map Number 06071C8607H) dated August 28, 2008. The entire project site is within Flood Hazard Zone “X” – an area to be determined to be outside the 0.2% annual chance of flood plain.
2 HYDROLOGY

2.1 Methodology
The tributary drainage area boundaries were delineated utilizing digital topography provided by recent aerial topography. Detailed hydrologic parameters used in this analysis can be found in the San Bernardino County Hydrology Manual.

2.1.1 General Guidelines
The following assumptions/guidelines were applied in the use of the Rational and Unit Hydrograph Methods:
·Hydrology studies were prepared using methodology outlined by the San Bernardino County Hydrology Manual. The developed condition was analyzed using the Rational Method. (See Developed Hydrology Map in Appendix A) The Rational Method is commonly used for determining peak discharge for areas less than 640 acres. The developed condition was analyzed using the rational method in order to determine peak flow rates.

Page 2185 of 3744 ends

·The rational method include the effects of infiltration caused by land use and soil surface characteristics. The Hydrologic Soils Group Map Area obtained from the San Bernardino County Stormwater Facility Mapping Tool indicates that the project study area consists of soil types A. Hydrologic soil ratings are based on a scale of A through D, where D is the least pervious, providing the greatest runoff.

The type of vegetation, percent ground cover, and percentage of impervious surfaces also affect the infiltration rate. See attached map in Appendix B. ·The land use type of undeveloped (average cover) was utilized for the existing and proposed landscape areas condition, commercial for proposed roads and residential (8 – 10 dwelling/acre) for proposed residential areas. ·Per criteria from the San Bernardino County Hydrology Manual, an Antecedent Moisture Condition (AMC) III was used for the 50-year and 100-year analyses that reflects the degree of ground saturation from previous rainfall events. The AMC value can range from I to III, with condition III being the most severe, allowing for greater runoff and low infiltration.

2.2 Rational Method
The Rational Method is an empirical computational procedure for developing peak discharge for storms of a specified recurrence interval in watersheds less than 640 acres. The formula is:

Q = CIA
Where:

Q = Peak discharge, in cubic feet per second.

C = Runoff coefficient representing the ratio of runoff depth to rainfall depth.

I = The time-averaged rainfall intensity for a storm duration equal to the time of concentration, in inches/hour (in./hr.).

A = Drainage area, in acres

2.2.1 Rational Method Guidelines
The following assumptions/guidelines were applied in the use of the Rational Method:
·The basic assumption for the Rational Method is that the precipitation rate is constant and uniform over the entire watershed for the time duration such that runoff could travel from the most remote point in the watershed to the concentration point; after which time the rate of runoff does not increase. This is the time defined as the "time of concentration (Tc)". The method is based on the assumption that the peak flow rate is directly proportional to drainage area, rainfall intensity, and a runoff coefficient "C," which is related to land use and soil type.
·Initial subareas were drawn to be less than 10 acres in size and less than 1,000 feet in length per the San Bernardino County Hydrology Manual guidelines for this procedure.

·The hydrology calculations assumed 100 percent interception of the surface runoff at the local area drain inlets. A future hydraulics analysis of the proposed storm drain system will estimate the total intercepted flow at each area drain inlet.

2.2.2 Rational Method Calculation Software
The hydrologic calculations were performed using software developed by “CIVILDESIGN” Engineering Software for the San Bernardino County Hydrology Manual. The 100-year storm event design discharge at intermediate points were computed by generating a hydrologic "link- node" model that divides the area into drainage sub-areas, each tributary to a concentration point or hydrologic "node" point determined by the existing and proposed terrain shown on the hydrology maps. Precipitation data for the project location was taken from NOAA’s National Weather Service precipitation data and is provided in Appendix B of this report. 3 HYDRAULICS

3.1 Debris Potential
Since this project site is located in a basically flat valley area, the potential for debris is not a concern.

3.2 Storm Drain Hydraulics
The Water Surface Pressure Gradient for Windows (WSPGW) program has been used to perform the storm drain facilities flow characteristics. The WSPG program was originally developed by the Los Angeles County Flood Control District in the late 1970’s (District program no. F0515) and has been modified in 1997 to a Microsoft Windows version. The Federal Emergency Management Agency (FEMA) has included the WSPG program in their list of acceptable software to model water surface elevations.

THE WSPGW program is based upon solving the Bernoulli equation for the total energy at each section using the Manning’s formula for friction loss between the sections in the channel reach.

The open channel flow procedure uses the Standard Step Method. Confluences, bridge piers, wall entrance and exits are analyzed using the pressure and momentum theory. The Bernoulli equation takes into account minor losses from bends, angle points, and manhole losses for pressure flow conditions. After computing a lower stage profile from the system headwork downstream to the system outlet (supercritical flow regime), and an upper stage water surface profile in the subcritical flow regime, WSPGW program will create a composite water surface profile for the entire system. Any hydraulic jumps present will be located by equating the total energy from both stages at various sections. In the reach analysis, the program automatically calculates the water surface profile at intermediate sections when the velocity head changes by more than 10%. In curved channel section, the program calculates the superelevation of the water surface level and applies a safety factor if the channel is other than rectangular, or if the flows are in the supercritical regime.

The hydraulics information will be entered into the WSPGW computer program by Civilcadd/Civildesign. Water surface elevations and velocities were calculated at specified

junctions, reaches and outlet points. The computer files for the 100-year calculations will be included in this report during final engineering.

3.3 Catch Basin Hydraulics
Catch basin calculations will be prepared during final engineering and will be performed using Bentley FlowMaster, Bentley Systems Inc.

3.4 Street Capacity Hydraulics
Street capacity calculations are prepared using Bentley FlowMaster, Bentley Systems Inc. The section analyzed was for the typical street section at the minimum proposed street grade of

0.5%. See Appendix D for detailed calculations.
4 SUMMARY
The Rational Method was used to determine the peak flow rates for the 50-year and 100-year storm events for Tract No. 20245 in its developed condition. Table 1 summarizes the peak flow rates for both storm events.

The provided street capacity calculations demonstrate the 100-year storm peak flow rate will be below finish floor elevations.

This study identifies the required storm drain infrastructure as well as peak flow rates for Tract No. 20245. Hydraulic and sizing calculations for proposed storm drain infrastructure will be provided during final engineering.

Description
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.

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.
