'VIRESAFE,
Inquire before you wire!
Wire Fraud Alert
This Notice is not intended to provide legal or professional advice. If you have any questions, please consult with a lawyer.

All parties to a real estate transaction are targets for wire fraud and many have lost hundreds of thousands of dollars because they simply relied on the wire instructions received via email, without further verification. If funds are to be wired in conjunction with this real estate transaction, we strongly recommend verbal verification of wire instructions through a known, trusted phone number prior to sending funds.

In addition, the following non-exclusive self-protection strategies are recommended to minimize exposure to possible wire fraud.
• NEVER RELY on emails purporting to change wire instructions. Parties to a transaction rarely change wire instructions in the course of a transaction.
• ALWAYS VERIFY wire instructions, specifically the ABA routing number and account number, by calling the party who sent the instructions to you. DO NOT use the phone number provided in the email containing the instructions, use phone numbers you have called before or can otherwise verify. Obtain the phone number of relevant parties to the transaction as soon as an escrow account is opened. DO NOT send an email to verify as the email address may be incorrect or the email may be intercepted by the fraudster. • USE COMPLEX EMAIL PASSWORDS that employ a combination of mixed case, numbers, and symbols. Make your passwords greater than eight (8) characters. Also, change your password often and do NOT reuse the same password for other online accounts.
• USE MULTI -FACTOR AUTHENTICATION for email accounts. Your email provider or IT staff may have specific instructions on how to implement this feature.

Surrounding sites were identified in the following databases.

Elevations have been determined from the USGS Digital Elevation Model and should be evaluated on a relative (not an absolute) basis. Relative elevation information between sites of close proximity should be field verified. Sites with an elevation equal to or higher than the target property have been differentiated below from sites with an elevation lower than the target property.

Page numbers and map identification numbers refer to the EDR Radius Map report where detailed data on individual sites can be reviewed.

Sites listed in bold italics are in multiple databases.

Unmappable (orphan) sites are not considered in the foregoing analysis.

STANDARD ENVIRONMENTAL RECORDS
Lists of Federal RCRA generators
RCRA-SQG: RCRAInfo is EPA's comprehensive information system, providing access to data supporting the Resource Conservation and Recovery Act (RCRA) of 1976 and the Hazardous and Solid Waste Amendments (HSWA) of 1984. The database includes selective information on sites which generate, transport, store, treat and/or dispose of hazardous waste as defined by the Resource Conservation and Recovery Act (RCRA). Small quantity generators (SQGs) generate between 100 kg and 1,000 kg of hazardous waste per month.

A review of the RCRA-SQG list, as provided by EDR, and dated 12/04/2023 has revealed that there is 1 RCRA-SQG site within approximately 0.25 miles of the target property.

ENVIROSTOR: The Department of Toxic Substances Control's (DTSC's) Site Mitigation and Brownfields Reuse Program's (SMBRP's) EnviroStor database identifes sites that have known contamination or sites for which there may be reasons to investigate further. The database includes the following site types: Federal Superfund sites (National Priorities List (NPL)); State Response, including Military Facilities and State Superfund; Voluntary Cleanup; and School sites. EnviroStor provides similar information to the information that was available in CalSites, and provides additional site information, including, but not limited to, identification of formerly -contaminated properties that have been released for reuse, properties where environmental deed restrictions have been recorded to prevent inappropriate land uses, and risk characterization information that is used to assess potential impacts to public health and the environment at contaminated sites.

A review of the ENVIROSTOR list, as provided by EDR, and dated 01/22/2024 has revealed that there is 1 ENVIROSTOR site within approximately 1 mile of the target property.

TC7624121.2s Page GR-2

GOVERNMENT RECORDS SEARCHED / DATA CURRENCY TRACKING
SEMS-ARCHIVE (Superfund Enterprise Management System Archive) tracks sites that have no further interest under the Federal Superfund Program based on available information. The list was formerly known as the CERCLIS-NFRAP, renamed to SEMS ARCHIVE by the EPA in 2015. EPA may perform a minimal level of assessment work at a site while it is archived if site conditions change and/or new information becomes available. Archived sites have been removed and archived from the inventory of SEMS sites. Archived status indicates that, to the best of EPA's knowledge, assessment at a site has been completed and that EPA has determined no further steps will be taken to list the site on the National Priorities List (NPL), unless information indicates this decision was not appropriate or other considerations require a recommendation for listing at a later time. The decision does not necessarily mean that there is no hazard associated with a given site; it only means that. based upon available information, the location is not judged to be potential NPL site.

US BROWNFIELDS: A Listing of Brownfields Sites
Brownfields are real property, the expansion, redevelopment, or reuse of which may be complicated by the presence or potential presence of a hazardous substance, pollutant, or contaminant. Cleaning up and reinvesting in these properties takes development pressures off of undeveloped, open land, and both improves and protects the environment.

Assessment, Cleanup and Redevelopment Exchange System (ACRES) stores information reported by EPA Brownfields grant recipients on brownfields properties assessed or cleaned up with grant funding as well as information on Targeted Brownfields Assessments performed by EPA Regions. A listing of ACRES Brownfield sites is obtained from Cleanups in My Community. Cleanups in My Community provides information on Brownfields properties for which information is reported back to EPA, as well as areas served by Brownfields grant programs.

The list represents deed restrictions that are active. Some sites have multiple deed restrictions. The DTSC Hazardous Waste Management Program (HWMP) has developed a list of current or former hazardous waste facilities that have a recorded land use restriction at the local county recorder's office. The land use restrictions on this list were required by the DTSC HWMP as a result of the presence of hazardous substances that remain on site after the facility (or part of the facility) has been closed or cleaned up. The types of land use restriction include deed notice, deed restriction, or a land use restriction that binds current and future owners.

EPA WATCH LIST: EPA Watch List
EPA maintains a "Watch List" to facilitate dialogue between EPA, state and local environmental agencies on enforcement matters relating to facilities with alleged violations identified as either significant or high priority. Being on the Watch List does not mean that the facility has actually violated the law only that an investigation by EPA or a state or local environmental agency has led those organizations to allege that an unproven violation has in fact occurred. Being on the Watch List does not represent a higher level of concern regarding the alleged violations that were detected, but instead indicates cases requiring additional dialogue between EPA, state and local agencies - primarily because of the length of time the alleged violation has gone unaddressed or unresolved.

2020 COR ACTION: 2020 Corrective Action Program List
The EPA has set ambitious goals for the RCRA Corrective Action program by creating the 2020 Corrective Action Universe. This RCRA cleanup baseline includes facilities expected to need corrective action. The 2020 universe contains a wide variety of sites. Some properties are heavily contaminated while others were contaminated but have since been cleaned up. Still others have not been fully investigated yet, and may require little or no remediation.

Inclusion in the 2020 Universe does not necessarily imply failure on the part of a facility to meet its RCRA obligations.

RMP: Risk Management Plans
When Congress passed the Clean Air Act Amendments of 1990, it required EPA to publish regulations and guidance for chemical accident prevention at facilities using extremely hazardous substances. The Risk Management Program Rule (RMP Rule) was written to implement Section 112(r) of these amendments. The rule, which built upon existing industry codes and standards, requires companies of all sizes that use certain flammable and toxic substances to develop a Risk Management Program, which includes a(n): Hazard assessment that details the potential effects of an accidental release, an accident history of the last five years, and an evaluation of worst -case and alternative accidental releases; Prevention program that includes safety precautions and maintenance, monitoring, and employee training measures; and Emergency response program that spells out emergency health care, employee training measures and procedures for informing the public and response agencies (e.g the fire department) should an accident occur.

PFAS NPDES: Clean Water Act Discharge Monitoring Information Any discharger of pollutants to waters of the United States from a point source must have a National Pollutant Discharge Elimination System (NPDES) permit. The process for obtaining limits involves the regulated entity (permittee) disclosing releases in a NPDES permit application and the permitting authority (typically the state but sometimes EPA) deciding whether to require monitoring or monitoring with limits. Caveats and Limitations:

Less than half of states have required PFAS monitoring for at least one of their permittees and fewer states have established PFAS effluent limits for permittees. New rulemakings have been initiated that may increase the number of facilities monitoring for PFAS in the future.

PFAS ECHO FIRE TRAINING: Facilities in Industries that May Be Handling PFAS Listing A list of fire training sites was added to the Industry Sectors dataset using a keyword search on the permitted facilitys name to identify sites where fire -fighting foam may have been used in training exercises. Additionally, you may view an example spreadsheet of the subset of fire training facility data, as well as the keywords used in selecting or deselecting a facility for the subset. as well as the keywords used in selecting or deselecting a facility for the subset. These keywords were tested to maximize accuracy in selecting facilities that may use fire -fighting foam in training exercises, however, due to the lack of a required reporting field in the data systems for designating fire training sites, this methodology may not identify all fire training sites or may potentially misidentify them.

PFAS PART 139 AIRPORT: All Certified Part 139 Airports PFAS Information Listing Since July 1, 2006, all certified part 139 airports are required to have fire -fighting foam onsite that meet military specifications (MIL -F-24385) (14 CFR 139.317). To date, these military specification fire -fighting foams are fluorinated and have been historically used for training and extinguishing. The 2018 FAA Reauthorization Act has a provision stating that no later than October 2021, FAA shall not require the use of fluorinated AFFF. This provision does not prohibit the use of fluorinated AFFF at Part 139 civilian airports; it only prohibits FAA from mandating its use. The Federal Aviation Administration?s document AC 150/5210-6D - Aircraft Fire Extinguishing Agents provides guidance on Aircraft Fire Extinguishing Agents, which includes Aqueous Film Forming Foam (AFFF).

EDR MGP: EDR Proprietary Manufactured Gas Plants
The EDR Proprietary Manufactured Gas Plant Database includes records of coal gas plants (manufactured gas plants) compiled by EDR's researchers. Manufactured gas sites were used in the United States from the 1800's to 1950's to produce a gas that could be distributed and used as fuel. These plants used whale oil, rosin, coal, or a mixture of coal, oil, and water that also produced a significant amount of waste. Many of the byproducts of the gas production, such as coal tar (oily waste containing volatile and non-volatile chemicals), sludges, oils and other compounds are potentially hazardous to human health and the environment. The byproduct from this process was frequently disposed of directly at the plant site and can remain or spread slowly, serving as a continuous source of soil and groundwater contamination.

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.

EDR's GeoCheck Physical Setting Source Addendum is provided to assist the environmental professional in forming an opinion about the impact of potential contaminant migration.

Assessment of the impact of contaminant migration generally has two principle investigative components:

1. Groundwater flow direction, and

2. Groundwater flow velocity.

Groundwater flow direction may be impacted by surface topography, hydrology, hydrogeology, characteristics of the soil, and nearby wells. Groundwater flow velocity is generally impacted by the nature of the geologic strata.

TC7624121.2s Page A-1

GEOCHECK® - PHYSICAL SETTING SOURCE SUMMARY

GROUNDWATER FLOW DIRECTION INFORMATION
Groundwater flow direction for a particular site is best determined by a qualified environmental professional using site -specific well data. If such data is not reasonably ascertainable, it may be necessary to rely on other sources of information, such as surface topographic information, hydrologic information, hydrogeologic data collected on nearby properties, and regional groundwater flow information (from deep aquifers).

TOPOGRAPHIC INFORMATION
Surface topography may be indicative of the direction of surficial groundwater flow. This information can be used to assist the environmental professional in forming an opinion about the impact of nearby contaminated properties or, should contamination exist on the target property, what downgradient sites might be impacted.

HYDROLOGIC INFORMATION
Surface water can act as a hydrologic barrier to groundwater flow. Such hydrologic information can be used to assist the environmental professional in forming an opinion about the impact of nearby contaminated properties or, should contamination exist on the target property, what downgradient sites might be impacted.

Refer to the Physical Setting Source Map following this summary for hydrologic information (major waterways and bodies of water).

HYDROGEOLOGIC INFORMATION
Hydrogeologic information obtained by installation of wells on a specific site can often be an indicator of groundwater flow direction in the immediate area. Such hydrogeologic information can be used to assist the environmental professional in forming an opinion about the impact of nearby contaminated properties or, should contamination exist on the target property, what downgradient sites might be impacted.

GROUNDWATER FLOW VELOCITY INFORMATION
Groundwater flow velocity information for a particular site is best determined by a qualified environmental professional using site specific geologic and soil strata data. If such data are not reasonably ascertainable, it may be necessary to rely on other sources of information, including geologic age identification, rock stratigraphic unit and soil characteristics data collected on nearby properties and regional soil information. In general, contaminant plumes move more quickly through sandy -gravelly types of soils than silty -clayey types of soils.

GEOLOGIC INFORMATION IN GENERAL AREA OF TARGET PROPERTY Geologic information can be used by the environmental professional in forming an opinion about the relative speed at which contaminant migration may be occurring.

Rancho Mirage Affordable Apartments
Preliminary Drainage Study
I. PROJECT DESCRIPTION
Purpose
The purpose of this drainage report is to provide hydrologic and hydraulic calculations in support of the preliminary plans for the Rancho Mirage Affordable Apartments project. This report will demonstrate compliance with the retention requirements of the City of Rancho Mirage and the methodology of the Riverside County Flood Control and Water Conservation District Hydrology Manual, dated April 1978.

Project Summary
The project is located within a portion of a vacant parcel west of Key Largo Avenue in the City of Rancho Mirage within Riverside County in the State of California. The project is proposed within a

5.00 -acre portion of larger city -owned parcel. The site is bounded by vacant land to the west, south, and east. The project is bounded to the north by currently vacant land planned for a future multifamily development, known as Via Vail Village, with proposed construction dates before that of the subject project. See the Vicinity Map below.

The proposed development includes seven multifamily buildings with a total of 150 residential units, as well as parking areas and outdoor amenity space. Offsite improvements include the construction of the public street, Via Vail, along the property frontage.

The site is located in FEMA Zone X, designated as an area of minimal flood hazard determined to be outside the 0.2% annual chance floodplain. The site is located within FEMA FIRM Panel No, 06065C1595G, effective date August 28, 2008, which can be found in Appendix C.

The site is located within the Indio Hydrologic Sub -Area (Sub -Area Number 719.47), Coachella Hydrologic Area, and Whitewater Hydrologic Unit, which ultimately drain toward the Salton Sea.

Rancho Mirage Affordable Apartments
Preliminary Drainage Study
II. EXISTING CONDITIONS
The existing 5.00 -acre site consists of vacant land covered in dune sand and sparse vegetation. Site elevations fall from southwest to northeast at an average grade of 3%.

Existing soils are sandy with relatively high infiltration rates. Groundwater was not encountered in geotechnical explorations and is anticipated to be approximately 160 feet below the ground surface.

See Appendix D for the full geotechnical investigation report.

Runoff that does not infiltrate drains across the northern property line onto the proposed site of the Via Vail Village project or across the eastern property line onto vacant land planned for the future public street extension of Via Vail and a vacant parcel to the northeast.

The site receives significant runon from surrounding vacant lands. The open space property to the west and portions of the vacant land to the south all drain through the site toward the Via Vail Village site and the land planned for the public street, Via Vail.

The adjacent Via Vail Village project proposes a temporary retention basin on the subject project site to capture any runoff that reaches the Via Vail Village site in the existing condition.

The existing area tributary to and including the project has been delineated into two sub -basins. E1 includes the project area and upstream area that reach the northern and eastern property lines, continuing northeast. E2 includes a small portion of the site and upstream area that drains north within the public park property. Drainage from this area is tributary to a future retention basin for the park parcel proposed per the Via Vail Village plans.

See the Existing Conditions Drainage Exhibit in AppendixAfor a graphic depiction of the existing sub - basins.

III. PROPOSED CONDITIONS
Proposed site improvements shall consist of seven multifamily housing buildings with surface parking and associated drive aisles, landscaping, pedestrian hardscape, and outdoor amenity areas.

Site grades generally drain southwest to northeast as in the existing condition.

Offsite improvements consist of the construction of the public street, Via Vail, fronting the property.

Via Vail will include a 40 -foot curb -to -curb drive aisle with a 6 -foot meandering sidewalk on the west side.

The proposed site has been delineated into the following sub -basins:

P1
P1 includes the onsite improvements. It includes runoff from roof, landscape, pedestrian hardscape, and vehicular hardscape areas. Drainage from roof areas will outlet at grade into planter areas surrounding the buildings. Landscape swales direct runoff to the area drain October 2024 3

system. Pedestrian sidewalks drain into the adjacent landscape areas or onto the drive aisle where applicable. Runoff in the drive aisle reaches a concrete gutter. Gutter flow is captured in inlets throughout the drive aisle. The private storm drain system collects runoff as described and conveys it to an underground storage tank, referred to as BMP 1.

Basin 1 is designed to retain the 100 -year storm. Drainage is stored underground and infiltrated over time. In an emergency overflow condition, drainage would enter an outlet pipe connected to an outlet structure. Overflow drainage may exit the system through the grate and surface flow to the Via Vail right-of-way.

P2
P2 consists of the area within the Via Vail right-of-way west of the centerline. The City of Rancho Mirage requires projects to collect and retain drainage from half of the right-of-way fronting each property. This drainage will be collected in a storm drain inlet and piped onsite toBMP1.

P3
P3 consists of the area within the right-of-way east of the centerline. The full width of Via Vail will be constructed to serve the project. While the project is not required to retain runoff from the eastern half of the right-of-way, the project proposes to collect and retain the drainage in BMP 1. P3 has been tabulated separately from P2 in order to tabulate the drainage the project would not typically be required to retain.

P4
P4 consists of the offsite area south of the site that is tributary to the site. This area is owned by the City of Rancho Mirage. The project proposes to collect the runoff and store in an offsite retention basin, referred to as BMP 2. BMP 2 is designed to retain the 100 -year storm from the public parcel through infiltration. In an overflow condition, drainage would overtop an emergency spillway and surface flow to the Via Vail right-of-way.

P5
P5 includes the portion of offsite, upstream area tributary to the easterly property line that naturally drains north toward the public basin proposed per the Via Vail Village project. The drainage will continue to be directed north with a swale. No additional retention feature is proposed for this area as the public retention basin per the Via Vail Village project has been designed for this area.

See the Proposed Conditions Drainage Exhibit in Appendix A for a depiction of the proposed sub - basins and retention features.

Rancho Mirage Affordable Apartments
Preliminary Drainage Study
IV. METHODOLOGY
Overview
The City of Rancho Mirage requires retention of the 100 -year storm, considering the worst -case duration between the 1, 3, 6, and 24 -hour storm durations. Hydrology calculations shall be performed in accordance with the Riverside County Hydrology Manual.

Hydrology
As the City of Rancho Mirage requires full retention of the 100 -year storm, the proposed condition hydrology is the focus of this study, as opposed to calculating a difference in flow from the existing condition.

The Hydrology Manual specifies Rational Method for the 1 -hour storm duration and the Synthetic Hydrograph Method for the 3 -hour, 6 -hour, and 24 -hour storms. The Synthetic Hydrograph Method considers distribution of rainfall over time, allowing storm volume over various storm durations to be calculated. Retention basin sizing is based on storm volumes, and it was therefore necessary to utilize the Synthetic Hydrograph Method for all four storm durations.

The Synthetic Hydrograph Method is typically utilized for watersheds over 300 acres. The Hydrology Manual specifies a Short Cut Synthetic Hydrograph Method for retention basin sizing for drainage areas of less than 200 acres with lag times less than eight minutes. The Short Cut Synthetic Hydrograph Method has been implemented for this project as the site is five acres and lag times are expected to be relatively short.

The methodology outlined in Plate E-1.2 of the Hydrology Manual was followed and is described in more detail below. References can be found in Appendix C. The calculations described below were performed in Microsoft Excel and are provided in Appendix B.

Point Precipitation
Point rainfall data was obtained for the project location from the isohyetal maps for the 100 - year storm for the 1, 3, 6, and 24 -hour durations from plates D-4.4, E-5.2, E-5.1, and E-5.6 of the Hydrology Manual.

As the drainage areas are relatively small, aerial adjustment per Plate E-5.8 was not necessary.

Precipitation Intensity Pattern
Hydrology Manual Plate E-5.9 provides rainfall patterns in percentage for various time increments for the 3, 6, and 24 -hour duration storms. A 5 -minute increment was used for the 1, 3, and 6 -hour duration storms. A 15 -minute time increment was used for the 24 -hour duration storm.

October 2024 5
674

Rancho Mirage Affordable Apartments
Preliminary Drainage Study
Plate E-5.9 does not provide a rainfall pattern for the 1 -hour duration storm. For the 1 -hour storm 5 -minute increments, the pattern provided for the 3 -hour storm in 15 -minute increments was utilized.

For each time increment across the duration of each storm considered, the point precipitation was multiplied by the precipitation intensity pattern percentage for the given time increment. This resulted in a rainfall intensity for each time increment.

Loss Rate
Anticipated runoff loss rates due to infiltration, surface interception, evaporation, and other factors were considered.

The runoff curve number was obtained for the pervious area from Plate E-6.1, utilizing the value for urban, residential areas with good coverage and Type A soils.

Next, the infiltrate rate for pervious areas (Fp) was obtained from Plate E-6.2. The Hydrology Manual recommends Antecedent Moisture Condition II for the 100 -year storm.

The percentage of imperviousness for each sub -basin was tabulated. The loss rate for pervious areas was then adjusted using the following equation:

F = Fp(1.00-0.9A;)
Where: F = Adjusted loss rate (in/hr)
Fp = Loss rate for pervious areas (in/hr)
A; = Impervious area (decimal percent)
For the 1,3, and 6 -hour durations, the loss is considered constant. For the longer duration storm of 24 -hours, the loss should be varied to decrease with time. The 24 -hour loss rate for each time increment was calculated per the following equation:

FT= [(F-Fm)/54](D-T)1'55 + Fm
Where: FT= Adjusted loss rate at time T (in/hr)
F = Adjusted loss rate (in/hr)
D = Storm duration (hr) = 24 hours
T = time from beginning of storm (hr)
Fm = Minimum value on the loss curve (in/hr)
Per plate E-1.1, Fm is typically 50 to 75 percent of F. It was considered 50 percent of F for these calculations.

For some time increments, the loss rate exceeded the rainfall in the given increment. In those increments, a low loss rate was calculated. Per Plate E-1.1, the low loss rate is typically 80 to 90 percent of the rain fall rate. For these calculations, 90 percent was selected.

October 2024 6
675

Rancho Mirage Affordable Apartments
Preliminary Drainage Study
Effective Rainfall Rate
The effective rainfall rate for each time increment was calculated by subtracting the loss rate from the rainfall intensity for the given increment.

Flood Hydrograph
The flow rate over each time increment was calculated by multiplying the effective rainfall rate by the sub -basin area. The result of the calculations is four time series of runoff over time for the four storm durations considered.

Basin Routing
In order to show retention of the 100 -year storm, BMP routing calculations needed to be performed.

BMP routing calculations were performed in the hydrology spreadsheet.

For each time increment, a volume of runoff was calculated by multiplying the runoff rate from the hydrograph time series by the time increment (ie. 5 minutes or 15 minutes).

Both BMPs were modeled as basins. BMP 1 is an underground storage vault with 90 percent void space. BMP 1 was modeled as a basin by considering the top area to be the same as the bottom area. The void space was considered by modeling the dimensions (length, width, and height) as the cube root of 90 percent multiplied by each of the proposed dimensions. BMP 1 also includes a gravel layer on all sides of the tank. Although this layer provides additional storage, its volume has, conservatively, not been included in the routing analysis.

For the basin shape, volume over various storage depths can be calculated using the volume equation for a pyramidal frustum based on the bottom area, top area, and depth per the following equation:

V = (1 /3) d (Atop + Abottom + (AtopAbottom)os)
Where: V = Volume at depth, d (CF)
d = depth of water in basin (ft)

Abottom = Area of the bottom of basin (SF)
Freeboard of 1 foot minimum is proposed for the retention BMPs. For the calculations, the top of basin was considered to be below the freeboard. Therefore, the maximum depth listed in the calculations is 1 foot below the graded top of basin.

Infiltration was considered based on the geotechnical testing in Appendix D. A factor of safety of 3 was utilized per the Whitewater River Region Stormwater Quality BMP Design Handbook for LID Appendix B, Table 1. The measured infiltration was divided by the factor of safety, resulting in a design infiltration rate. Calculations are provided in Appendix B.

For each time increment, the volume of drainage infiltrated was calculated based on the basin area and the design infiltration rate.

Preliminary Drainage Study
Where the infiltration volume calculated exceeded the incoming flow volume for the time period, the infiltrated volume in the time period was considered to be the incoming flow volume. Where the incoming flow volume exceeded the infiltration volume, the volume needing to be stored in the basin was calculated as the incoming flow volume less the infiltration volume.

At each step, the incoming flow volume minus the infiltrated volume was added to the basin storage volume from the previous time step, resulting in the current volume being stored in the basin at each time step. The volume equation above was utilized to calculate the depth of water for the volume of water in the basin at each time step.

If the volume needing storage exceeded the maximum storage of the basin, the difference between water volume needing storage and the maximum storage would be the volume overflowing from the basin at the given time period. That volume would then be divided by the time increment length to calculate an overflow rate at the given time period.

If the volume needing storage never exceeded the maximum storage, the storm can be considered fully retained with no overflow from the basin.

Basin Drawdown
Retention basin drawdown was calculated by dividing the high water depth by the design infiltration rate. Calculations are provided in Appendix B.

Pipes Sizing
Pipes, gutters, and curb inlets were not sized in preliminary engineering. In final engineering, public pipes, gutters and curb inlets will be sized per the Riverside County Flood Control Water Conservation District Hydraulic Design Manual, dated 2024. The Hydraulic Design Manual requires pipes to be sized for the 100 -year storm with the hydraulic grade line at least 0.5 feet below ground surface. The manual requires gutter and inlet drainage to allow the 10 -year storm to be contained within the limits of the curbs and the 100 -year storm to be contained within the limits of the right-of- way.

Private onsite pipes, curbs, and gutters will be sized to ensure no flooding reaches the proposed buildings in the 100 -year storm.

3.0 The results of the routing analysis verify that the proposed retention BMPs have been sized adequately to retain the 100 -year storm event with adequate freeboard and that the facilities will drawdown fully within appropriate time frames. The County of Riverside Hydraulic Design Manual recommends 72 hours for detention basin drawdown, which this project is considering an appropriate guideline for retention BMPs.

Hydraulic analysis of pipes, inlets, and gutters will be provided in final engineering.

VI. WATER QUALITY NOTE
The project is located within the Whitewater River MS4 Region. Water quality requirements are addressed in a separate Water Quality Management Memo and are not discussed in this report.

VII. CONCLUSION
The proposed retention BMPs have been adequately designed to meet the City of Rancho Mirage retention requirements. In a 100 -year storm of durations 1 -hour, 3 -hour, 6 -hour, and 24 -hour, runoff will remain within the retention BMPs and underground pipe system, posing no threat to people or structures. Overflow structures and overland flow paths to the Via Vail right-of-way are provided for conditions exceeding the 100 -year storm.

VIII. DECLARATION OF RESPONSIBLE CHARGE
I hereby declare that I am the engineer of work for this project, that I have exercised responsible charge over the design of the project as defined in Section 6703 of the Business and Profession Code, and that the design is consistent with the prevailing standard of the engineering profession for similar work.

I understand that the check of project drawings and specifications by the City of Rancho Mirage is confined to a review only and does not relieve me, as engineer of work, of my responsibilities for the project design.

Basin is zeroed out by reducing variables to 0.001, Zero would crash spreadsheet. (Drywell can be "zeroed out" by reducing numbers to less than .001, but should not entered as zeros or program chokes.) Drywell storage includes 40% of the 1' wide rock bed surrounding the drywell: formula (upper)*PIQ*(diam/2)^2+(lower)*PI()*((diam/2)^2+0.4*((diam/2+(grav+0.4166))^2•(diam/2+0.4166)^2)) The drywell wall thickness is assumed at 5" (0.4166) and the gravel bed width is variable "gray" Drywell design factors Upper sec.
