Ms. Isabel Ronda
Relevant Group
6417 Selma Avenue, 2nd Floor
Los Angeles, Ca 90028
Re: Limited Phase II Environmental Site Assessment (ESA) Ranch Project being an approximately 86-acre property, on the Southwest Corner of Avenue 52 and Van Buren Street in Coachella, California.

Dear Ms. Ronda:

Kimley-Horn and Associates, Inc. (“Kimley-Horn” or “Consultant”) is pleased to submit this Limited Phase II ESA to Relevant Group (“Client”) for the Ranch Project as defined by Assessor Parcel Numbers (APN’s) 780-040-001, 780-040-003, 780-060-002, and 780-060-001 herein referenced as the Subject Property. The Subject Property consists of approximately 86-acre on the Southwest corner of Avenue 52 and Van Buren Street in Coachella, CA, California.

The intent of this limited Phase II (ESA) on the Subject Property is to determine the absence/presence of hazardous and petroleum materials in concentrations of concern.

1.0 Background:

1.1 An ASTM E-1527-13 Phase I ESA was completed for the Ranch Project by Sladden Engineering in June 2024. Based on the recommendations of the Phase I ESA, Kimley-Horn’s proposed a Limited Phase II ESA to address the Recognized Environmental Concern (REC) identified within the Phase I ESA, which included the following:

REC 1: “Previous and ongoing farming/agricultural use of the subject property along with the previous environmental reports identify the presence of DDE, DDT and other hydrocarbon, we recommend that a Phase 2 shallow soil sampling laboratory testing program be performed.”

1.2 Additionally, a historical memorandum dated June 26, 2008, indicated a Phase I ESA and Phase II ESA were completed by Moore Twinning in 2008 with results indicating the following:
• Summary 1: “General areas of the site were assessed for environmental persistent chemicals (OCPs and arsenic). The results revealed detectable concentrations of DDE and DDT in the near surface soil and attenuated with depth to two deep below ground surface (bgs). However, the environmental concerns associated with these are low and are below regulatory threshold”.
2124
Item 2.
2 • Summary 2: “However, near the existing metal shed and in the vicinity of the residence of the site the results from the soil sample indicated concentrations of the OCPs, DDE & DDT, which exceed the regulatory levels. {any soils on the site with high concentration will need to be removed offsite as a hazardous material}”
Kimely-Horn was not able to discern which regulatory threshold the above-mentioned results were compared to and note that changes in thresholds have occurred since 2008 for the low detections of OCPs.

2.0 Scope Rationale:

2.1 To address the REC identified within the Sladden Phase I ESA and Summary 1 from the Moore Twinning Phase IIs, Kimely-Horn completed soil sampling within the active agricultural fields following DTSC and CalEPA’s Interim Guidance for Sampling Agricultural Properties (Interim Guidance).

2.2 Based on Section 3.3 of the Interim Guidance where two crops were grown on the site, only discrete samples from within the same crop area may be composited. Since both date palms and grapes have been grown on the property, two distinct site areas were sampled following the Interim Guidance defined as Area 1 and Area 2. Areas 1 and 2 are defined by the agricultural field sampling within Sections 3.0 and 4.0 below and depicted in Figure 1, Subject Property Plan and Boring Location Map.
• Area 1 is defined as the date grove (TBX) borings within the approximately 50-acre date grove. • Area 2 is defined as the grape vines (GPX) boring within the approximately 26-acre grape vineyard.

2.3 To address Summary 2 and potential exceedances of DDE and DDT, which were reported in 2008, Kimley-Horn completed three soil samples (RX). Laboratory sampling procedures are described in Section III, Soil Sampling Investigation.

3.0 Soil Sampling Investigation

3.1 Agricultural Field Sampling: The Interim Guidance assumes a relatively even distribution of chemicals across an agricultural field of a property, and recommends compositing discrete samples to allow for increased sampling coverage for the Subject Property. Composite surface samples are made up of a maximum of four discrete surface samples from adjacent sampling locations. Analysis of the composite samples is determined by the following Sections of the Interim Guidance:
• Section 3.1.1 states “Based on data from former agricultural properties over the past seven years, the only pesticide class requiring analyses at agricultural properties are OCPs” 2125
Item 2.
3 • Section 3.1.2 states “Based on data from former agricultural properties, the only heavy metal required for routine analyses for these properties is arsenic”

3.2 Area 1: Only July 6, 2024, a total of 64 discrete soil samples were completed based on gridded sampling plan to a depth of 1-foot below ground surface (bgs). The borings were completed using a hand auger and samples were collected from 0.5-1.0-feet bgs with similar volume. The 64 discrete samples were composited into 16 samples as describe in Section 3.4. The location of the discrete and composited samples is illustrated in Figure 1, Subject Property Plan and Boring Location Map.

3.3 Area 2: Additionally on July 6, 2024, a total of 36 discrete soil samples were completed based on gridded sampling plan to a depth of 1-foot bgs. The borings were completed using a hand auger and samples were collected from 0.5-1.0-feet bgs with similar volume. The 36 discrete samples were composited into 9 samples as describe in Section 3.4.

3.4 Upon completion of the four discrete samples within one grid area, the samples were homogenized and one discrete sample collected and placed within a laboratory provided container. Additionally, one sample was completed for arsenic analysis co-located with one of the discrete pesticide samples based on the sampling events described in Section 3.2 and 3.3.

3.5 The soil samples were placed in a cooler and delivered to a state-certified laboratory under chain-of-custody protocol.

3.6 Residential Sampling: Only July 6, 2024, a total of three (3) discrete soil samples were completed to a depth of 1-foot below ground surface (bgs). The borings were completed using a hand auger and samples were collected from 0.5-1.0-feet bgs with similar volume. Samples for total petroleum hydrocarbon (TPH) analyses were collected using Terra Core® samplers. Soil for additional analyses were collected in laboratory supplied jars from the sampler. Locations are defined below:
• One sample was completed in the vicinity of a metal shed; however, it is unknown if the same shed identified within the 2008 analysis (R1)
• One sample adjacent to onsite well and fertilizer tote (R2). • One sample was completed south of the residential structure (R3).

3.7 The location of the discrete samples surrounding the residence is illustrated in Figure 1, Subject Property Plan and Boring Location Map.

3.8 Based on the results discussed in Section 4 – Soil Sampling Results, exceedances were identified within two of the three samples. Kimley-Horn remobilized on September 6, 2024, to complete samples surrounding the initial boring to a depth of 3-feet bgs. Figure 2, R2 Step-out Sampling Locations and Results and Figure 3, R3 Step-out Sampling Locations and Results depicts where the step out locations were completed surrounding the soil borings. Details pertaining to the results are reported in Section 4- Soil Sampling Results. 2126
Item 2.
4 4.0 Laboratory Analysis

4.1 Agricultural Field Sampling Analysis: The soil samples completed within the agricultural fields were analyzed for the following:
• California Title 22 metals by EPA Method 6010 analyzed by arsenic only. • Pesticides by EPA Method 8081.

4.2 Residential Sampling Analysis: Samples near the residential structures were analyzed for the following:
• Pesticides by EPA Method 8081.
• California Title 22 metals by EPA Method 6010 analyzed by arsenic only. • Total petroleum hydrocarbons as gasoline range organics (TPH-GRO), diesel range organics (TPH-DRO), and oil range organics (TPH-ORO) by EPA Method 8015.

The above analytical parameter list is consistent with the constituents of concern potentially present at the site based on the past operations identified during completion of the Phase I ESA.

5.0 Soil Sampling Results

5.1 Field Observations: No staining, odors were observed in the samples that would indicate the presence of contaminants.

5.2 Laboratory Results: The analytical results for soil are summarized in Tables 1, 2, 3 and 4. The laboratory analysis reports are included in Attachment A. Key results from the July 2024 sampling are summarized below.

5.2.1 No exceedances of pesticides or arsenic were identified in Area 1 or Area 2 of the agricultural field sampling.
2127
Item 2.
5 5.2.2 No exceedances of pesticides, arsenic or TPH were identified in the residential soil sampling except for the following described in Section 5.2.3 and 5.2.4.

5.2.3 One exceedance of 4,4-DDE was detected in sample R2-1 adjacent to the water well and fertilizer storage area in the July 6, 2024, sampling event with the detection of 2.40 mg/kg.

Three step-out borings were completed on September 6, 2024, as depicted in Figure 2, R2-Step-out Sampling Locations and Results. Additionally, a confirmation sample was completed at 1-ft and 2-ft bgs at the original location, which were below a residential standard. Each step-out sample was below the residential screening level.

5.2.4 One exceedance of Dieldrin was detected in sample R3-1 adjacent to the former residence from the July 6, 2024, sampling event with the detection of 0.096 mg/kg. Four step-out and a replicate from the initial borings were completed on September 6, 2024, surrounding the original boring to a depth of 3-feet bgs. See Figure 3, R3-Step-out Sampling Locations and Results with the following results:
• Initial boring:
o R3-1: 0.096 mg/kg
o R3B-1: 0.039 mg/kg
o R3B-2: 0.016 mg/kg
• Step outs:
o North
▪ R3N-1: 0.091 mg/kg
▪ R3N-2: 0.016 mg/kg
o South
▪ R3S-1: 0.026 mg/kg
o East
▪ R3E-1: 0.10 mg/kg
▪ R3E-2: 0.073 mg/kg
▪ R3E-3: 0.042 mg/kg
o West
▪ R3W-1: 0.042 mg/kg
▪ R3W-2: 0.0075 mg/kg

6.0 Conclusions

6.1 Agricultural Field Sampling: The laboratory analytical results do not indicate evidence for significant release(s) associated with the historical agricultural operations conducted at the Subject Property based on the REC identified within the Sladden Phase I ESA. The detected levels of pesticides are below the California Regional Water Quality Control Board (RWQCB)-San Francisco Region Environmental Screening Levels (ESLs) for residential soil and for the protection of soil and groundwater and would not likely trigger actions if reported to a regulatory agency.

6.2 Agricultural Field Sampling: Arsenic was detected at concentrations that exceed the ESLs for residential soil; however, the concentrations of arsenic reported in the soil samples collected during this investigation are below the typical Southern California background level of 2128
Item 2.
6 11 mg/kg per California Department of Toxic Substances Control (DTSC), Human and Ecological Risk Office (Hero).

6.3 Residential Sampling: Areas around the former residential structure indicate exceedances above residential screening level for 4,4-DDE at the R2 location and dieldrin at the R3 location. As the properties intent is for residential development, these de minims areas should be isolated or removed prior to mass grading. The summary within this report identifies the extents for isolation and removal based on depth and visually described within Figures 3 and 4. If the property is planned for commercial development versus residential, the detections of 4,4-DDE is below the 8.27 mg/kg screening level and dieldrin is below the 1.6 mg/kg screening level.

6.4 Please note that the results and conclusions in this report are based on, and limited to, the soil the limited soil investigation and the laboratory analyses that were completed.

6.5 Should you have any questions about these results, or wish to conduct additional investigations, please contact us at [email protected] or [email protected].

1 INTRODUCTION
This Noise and Vibration Analysis has been completed to determine the noise impacts associated with the development of the proposed COVA (“Project”). This noise and vibration analysis briefly describes the Project, provides information regarding noise fundamentals, sets out the local regulatory setting, presents the study methods and procedures for noise analysis, evaluates the future exterior noise environment, potential off‐site traffic impacts, the Project‐related long‐term stationary‐source operational noise, and Project‐related short‐term construction noise and vibration impacts.

1.1 SITE LOCATION
The Project is located at the southwest corner of the Van Buren Street and Avenue ͱͮ intersection in the City of Coachella. The Project is surrounded by agricultural uses to the north, east, south, and west, as shown in Exhibit ͭ‐ͭ.

1.2 PROJECT DESCRIPTION
The proposed Project consists of ͮͳͲ units: ͳͲ two‐story single‐family residences (SFR) with Ͱ to Ͳ bedrooms, ͭͬͬ stacked flat units at three stories with ͯ to Ͱ bedrooms, and ͭͬͬ hotel casitas and cottages for short‐term accommodations. The development includes a crystal lagoon and other residential amenities, including restaurants, a beach club, event space, pop‐up shops, outdoor amphitheater, pools, recreation areas, and kids' play spaces. A preliminary site plan for the Project is shown in Exhibit ͭ‐ͮ.

2 FUNDAMENTALS
Noise is simply defined as “unwanted sound.” Sound becomes unwanted when it interferes with normal activities, when it causes actual physical harm, or when it has adverse effects on health.

Noise is measured on a logarithmic scale of sound pressure level known as a decibel (dB). A‐ weighted decibels (dBA) approximate the subjective response of the human ear to a broad frequency noise source by discriminating against very low and very high frequencies of the audible spectrum.

They are adjusted to reflect only those frequencies that are audible to the human ear. Exhibit ͮ‐ͭ presents a summary of the typical noise levels and their subjective loudness and effects that are described in more detail below.

EXHIBIT 2-1: TYPICAL NOISE LEVELS

2.1 RANGE OF NOISE
Since the range of intensities that the human ear can detect is so large, the scale frequently used to measure intensity is a scale based on multiples of ͭͬ, the logarithmic scale. The scale for measuring intensity is the decibel scale. Each interval of ͭͬ decibels indicates a sound energy ten times greater than before, which is perceived by the human ear as being roughly twice as loud. (ͮ) The most common sounds vary between Ͱͬ dBA (very quiet) to ͭͬͬ dBA (very loud). Normal conversation at three feet is roughly at Ͳͬ dBA, while loud jet engine noises equate to ͭͭͬ dBA at approximately ͭ,ͬͬͬ feet, which can cause serious discomfort. (ͯ) Another important aspect of noise is the duration of the sound and the way it is described and distributed in time. 2333

ʹ

2.2 NOISE DESCRIPTORS
Environmental noise descriptors are generally based on averages, rather than instantaneous noise levels. The most used metric is the equivalent level (Leq). Equivalent sound levels are not measured directly but are calculated from sound pressure levels typically measured in A‐weighted decibels (dBA). The equivalent sound level (Leq) represents a steady state sound level containing the same total energy as a time‐varying signal over a given sample period and is commonly used to describe the “average” noise levels within the environment.

Peak hour or average noise levels, while useful, do not completely describe a given noise environment. Noise levels lower than peak hour may be disturbing if they occur during times when quiet is most desirable, namely evening and nighttime (sleeping) hours. To account for this, the Community Noise Equivalent Level (CNEL), representing a composite ͮͰ‐hour noise level, is utilized.

The CNEL is the weighted average of the intensity of a sound, with corrections for time of day, and averaged over ͮͰ hours. The time‐of‐day corrections require the addition of ͱ decibels to dBA Leq sound levels in the evening from ͳ:ͬͬ p.m. to ͭͬ:ͬͬ p.m., and the addition of ͭͬ decibels to dBA Leq sound levels at night between ͭͬ:ͬͬ p.m. and ͳ:ͬͬ a.m. These additions are made to account for the noise‐sensitive time periods during the evening and night hours when noise can become more intrusive. CNEL does not represent the actual sound level heard at any time, but rather represents the total sound exposure. The City of Coachella relies on the ͮͰ‐hour CNEL level to assess land use compatibility with transportation‐related noise sources.

2.3 SOUND PROPAGATION
When sound propagates over a distance, it changes in level and frequency content. The way noise reduces with distance depends on the following factors.

2.3.1 Geometric Spreading
Sound from a localized source (i.e., a stationary point source) propagates uniformly outward in a spherical pattern. The sound level attenuates (or decreases) at a rate of Ͳ dB for each doubling of distance from a point source. Highways consist of several localized noise sources on a defined path and hence can be treated as a line source, which approximates the effect of several point sources.

Noise from a line source propagates outward in a cylindrical pattern, often referred to as cylindrical spreading. Sound levels attenuate at a rate of ͯ dB for each doubling of distance from a line source. (ͮ)

2.3.2 Ground Absorption
The propagation path of noise from a highway to a receiver is usually very close to the ground. Noise attenuation from ground absorption and reflective wave canceling adds to the attenuation associated with geometric spreading. Traditionally, the excess attenuation has also been expressed in terms of attenuation per doubling of distance. This approximation is usually sufficiently accurate for distances of less than ͮͬͬ ft. For acoustically hard sites (i.e., sites with a reflective surface between the source and the receiver, such as a parking lot or body of water), no excess ground attenuation is assumed. For acoustically absorptive or soft sites (i.e., those sites with an absorptive ground surface between the source and the receiver such as soft dirt, grass, or scattered bushes and trees), an excess ground attenuation value of ͭ.ͱ dB per doubling of distance is normally assumed. 2334
Item 2.
ͭͲͱͱͮ‐ͬͮ NA
͵
When added to the cylindrical spreading, the excess ground attenuation results in an overall drop‐ off rate of Ͱ.ͱ dB per doubling of distance from a line source. (Ͱ)

2.3.3 Atmospheric Effects
Receivers located downwind from a source can be exposed to increased noise levels relative to calm conditions, whereas locations upwind can have lowered noise levels. Sound levels can be increased at large distances (e.g., more than ͱͬͬ feet) due to atmospheric temperature inversion (i.e., increasing temperature with elevation). Other factors such as air temperature, humidity, and turbulence can also have significant effects. (ͮ)

2.3.4 Shielding
A large object or barrier in the path between a noise source and a receiver can substantially attenuate noise levels at the receiver. The amount of attenuation provided by shielding depends on the size of the object and the frequency content of the noise source. Shielding by trees and other such vegetation typically only has an “out of sight, out of mind” effect. That is, the perception of noise impact tends to decrease when vegetation blocks the line‐of‐sight to nearby residents. However, for vegetation to provide a substantial, or even noticeable, noise reduction, the vegetation area must be at least ͭͱ feet in height, ͭͬͬ feet wide and dense enough to completely obstruct the line‐of‐sight between the source and the receiver. This size of vegetation may provide up to ͱ dBA of noise reduction. The Federal Highway Administration (FHWA) does not consider the planting of vegetation to be a noise abatement measure. (ͱ)

2.4 NOISE CONTROL
Noise control is the process of obtaining an acceptable noise environment for an observation point or receiver by controlling the noise source, transmission path, receiver, or all three. This concept is known as the source‐path‐receiver concept. In general, noise control measures can be applied to these three elements.

2.5 NOISE BARRIER ATTENUATION
Effective noise barriers can reduce noise levels by ͭͬ to ͭͱ dBA, cutting the loudness of traffic noise in half. A noise barrier is most effective when placed close to the noise source or receiver. Noise barriers, however, do have limitations. For a noise barrier to work, it must block the line‐of‐sight path of sound from the noise source.

2.6 LAND USE COMPATIBILITY WITH NOISE
Some land uses are more tolerant of noise than others. For example, schools, hospitals, churches, and residences are more sensitive to noise intrusion than commercial or industrial developments and related activities. As ambient noise levels affect the perceived amenity or livability of a development, so too can the mismanagement of noise impacts impair the economic health and growth potential of a community by reducing the area’s desirability as a place to live, shop and work.

For this reason, land use compatibility with the noise environment is an important consideration in the planning and design process. The FHWA encourages State and Local government to regulate land development in such a way that noise‐sensitive land uses are either prohibited from being located adjacent to a highway, or that the developments are planned, designed, and constructed in such a way that noise impacts are minimized. (Ͳ)

2.7 COMMUNITY RESPONSE TO NOISE
Approximately sixteen percent of the population has a very low tolerance for noise and will object to any noise not of their making. Consequently, even in the quietest environment, some complaints may occur. Twenty to thirty percent of the population will not complain even in very severe noise environments. (ͳ pp. ʹ‐Ͳ) Thus, a variety of reactions can be expected from people exposed to any given noise environment.

Surveys have shown that community response to noise varies from no reaction to vigorous action for newly introduced noises averaging from ͭͬ dB below existing to ͮͱ dB above existing. (ʹ) According to research originally published in the Noise Effects Handbook (ͳ), the percentage of high annoyance ranges from approximately ͬ percent at Ͱͱ dB or less, ͭͬ percent are highly annoyed around Ͳͬ dB, and increases rapidly to approximately ͳͬ percent being highly annoyed at approximately ʹͱ dB or greater. Despite this variability in behavior on an individual level, the population can be expected to exhibit the following responses to changes in noise levels as shown on Exhibit ͮ‐ͮ. A change of ͯ dBA is considered barely perceptible, and changes of ͱ dBA are considered readily perceptible. (Ͱ)

2.8 VIBRATION
Per the Federal Transit Administration (FTA) Transit Noise and Vibration Impact Assessment Manual, vibration is the periodic oscillation of a medium or object. The rumbling sound caused by the vibration of room surfaces is called structure‐borne noise. Sources of ground‐borne vibrations 2336
Item 2.
ͭͲͱͱͮ‐ͬͮ NA
ͭͭ
include natural phenomena (e.g., earthquakes, volcanic eruptions, sea waves, landslides) or human‐ made causes (e.g., explosions, machinery, traffic, trains, construction equipment). Vibration sources may be continuous, such as factory machinery, or transient, such as explosions. As is the case with airborne sound, ground‐borne vibrations may be described by amplitude and frequency.

Additionally, in contrast to airborne noise, ground‐borne vibration outdoors is not a common environmental problem, and annoyance from ground‐borne vibration is almost exclusively an indoor phenomenon (ʹ). Therefore, the effects of vibrations should only be evaluated at a structure, and the effects of the building structure on the vibration should be considered. Wood‐frame buildings, such as typical residential structures, are more easily excited by ground vibration than heavier buildings.

In contrast, large masonry buildings with spread footings have a low response to ground vibration (ʹ). In general, the heavier a building is, the lower the response will be to the incident vibration energy. However, all structures reduce vibration levels due to the coupling of the building to the soil.

There are several methods used to quantify vibration levels. Peak Particle Velocity (PPV) is defined as the maximum instantaneous peak of a vibration signal and is most commonly used to evaluate the impact of vibration on buildings (͵) (ʹ). However, PPV is not always suitable for assessing human response (e.g., annoyance), as the human body does not respond instantly to vibration signals.

Instead, it responds to the average amplitude, more accurately represented by the Root Mean Square (RMS) value of the vibration (ʹ).

RMS is defined as the square root of the average of the squared signal amplitude and is commonly used to evaluate human exposure to vibration. RMS and PPV are mathematically related—RMS is typically about ͳͬ% of the PPV for certain waveforms (ͭͬ) (ͭͭ). However, deriving RMS from PPV requires knowing the full waveform or making assumptions (e.g., sinusoidal or steady‐state signals).

Without this information, converting PPV to RMS introduces uncertainty and provides limited insight, especially in cases involving transient or impact vibrations (ͭͮ).

This distinction is important because human annoyance to vibration is often triggered by abrupt, intermittent events, rather than sustained energy levels. Construction‐related vibrations are typically impulsive and broadband, in contrast to the continuous, tonal vibrations associated with transit systems. The FTA's RMS‐based criteria were developed with train activity in mind and are not well‐suited for construction vibration, where perception is driven by factors like suddenness, impact, and repetition (ʹ).

In essence, RMS tends to average out short‐duration, high‐intensity events—the very events that people find most disturbing. Therefore, for construction activities, PPV‐based thresholds, such as those recommended by Caltrans, are more appropriate for assessing potential human annoyance and structural impact (ͭͭ).

While not universally accepted, vibration decibel notation (VdB) is another RMS‐based vibration notation developed and used by the FTA in their guidance manual to describe vibration levels and provide a background of common vibration levels and set vibration limits (ʹ). Decibel notation (VdB) serves to reduce the range of numbers used to describe vibration levels and is used in this report to describe vibration levels.

As stated in the FTA guidance manual, the background vibration‐velocity level in residential areas is generally ͱͬ VdB. Ground‐borne vibration is normally perceptible to humans at approximately Ͳͱ VdB. For most people, a vibration‐velocity level of ͳͱ VdB is the approximate dividing line between 2337
Item 2.
ͭͲͱͱͮ‐ͬͮ NA
ͭͮ
barely perceptible and distinctly perceptible levels. Typical outdoor sources of perceptible ground‐ borne vibration are construction equipment, steel‐wheeled trains, and traffic on rough roads. If a roadway is smooth, the ground‐borne vibration is rarely perceptible. The range of interest is from approximately ͱͬ VdB, which is the typical background vibration‐velocity level, to ͭͬͬ VdB, which is the general threshold where minor damage can occur in fragile buildings. Exhibit ͮ‐C illustrates common vibration sources and the human and structural response to ground‐borne vibration.

3 REGULATORY SETTING
To limit population exposure to physically and/or psychologically damaging as well as intrusive noise levels, the federal government, the State of California, various county governments, and most municipalities in the state have established standards and ordinances to control noise. In most areas, automobile and truck traffic is the major source of environmental noise. Traffic activity generally produces an average sound level that remains constant with time. Air and rail traffic, and commercial and industrial activities are also major sources of noise in some areas. Federal, state, and local agencies regulate different aspects of environmental noise. Federal and state agencies generally set noise standards for mobile sources such as aircraft and motor vehicles, while regulation of stationary sources is left to local agencies.

3.1 STATE OF CALIFORNIA NOISE REQUIREMENTS
The State of California regulates freeway noise, sets standards for sound transmission, provides occupational noise control criteria, identifies noise standards, and provides guidance for local land use compatibility. State law requires that each county and city adopt a General Plan that includes a Noise Element which is to be prepared according to guidelines adopted by the Governor’s Office of Planning and Research. (ͭͯ) The purpose of the Noise Element is to limit the exposure of the community to excessive noise levels. In addition, the California Environmental Quality Act (CEQA) requires that all known environmental effects of a project be analyzed, including environmental noise impacts.

3.2 STATE OF CALIFORNIA BUILDING STANDARDS CODE
The State of California’s Green Building Standards Code contains mandatory measures for non‐ residential building construction in Section ͱ.ͱͬͳ on Environmental Comfort. (ͭͰ) These noise standards are applied to new construction in California to control interior noise levels resulting from exterior noise sources. The regulations specify that acoustical studies must be prepared when non‐ residential structures are developed in areas where a general plan or airport plan provides contours that show exterior noise levels exceed Ͳͱ dBA CNEL, such as within a noise level contour of an airport, freeway, or railroad; or if contours are unavailable, buildings exposed to a noise level of Ͳͱ dBA Leq‐ͭ‐hr during any hour of operation; shall be constructed to provide an interior noise level environment attributable to exterior sources that does not exceed an hourly equivalent level of ͱͬ dBA Leq in occupied areas during any hour of operation.

3.3 CITY OF COACHELLA GENERAL PLAN NOISE ELEMENT
The City of Coachella has adopted a Noise Element of the General Plan as a tool for local planners to use in achieving and maintaining land uses that are compatible with environmental noise levels. (ͭͱ) The Noise Element identifies noise goals and policies to protect City of Coachella residents from excessive noise. The goals of the Noise Element are as follows:
2339
Item 2.
ͭͲͱͱͮ‐ͬͮ NA
ͭͰ
Goal ͭ Land Use Planning and Design. A community where noise compatibility between differing types of land uses is ensured through land use planning and design strategies.

Goal ͮ Stationary Source Noise. A community where excessive noise from stationary sources is minimized.

Goal ͯ Mobile Source Noise. A community where excessive noise from mobile sources is minimized.

To ensure noise‐sensitive land uses are protected from high levels of noise (Goal ͭ), Exhibit ͯ‐ͭ identifies exterior noise level guidelines for new developments impacted by transportation noise sources such as arterial roads, freeways, airports, and railroads. In addition, Table ͭ of the Noise Technical Appendix provides an exterior noise level standard of Ͳͱ dBA CNEL and an interior noise level standard of Ͱͱ dBA CNEL for new residential developments impacted by transportation noise.

The Noise Element also requires the analysis of new developments, as necessary, to identify mitigation measures to reduce noise levels to those found in Exhibit ͯ‐ͭ.

The noise criteria identified in the City of Coachella Noise Element are guidelines to evaluate the land use compatibility of transportation‐related noise. The compatibility criteria, shown on Exhibit ͯ‐A, provide the City with a planning tool to gauge the compatibility of land uses relative to existing and future exterior noise levels.

Exhibit ͯ‐A provides guidelines to evaluate the acceptability of the transportation‐related noise level impacts. These guidelines are based on the Governor’s Office of Planning and Research and are used to assess the long‐term traffic noise impacts on land uses. According to the land use compatibility guidelines of the General Plan, the utility/institutional land use of the Project is considered clearly compatible with exterior noise levels approaching ͳͬ dBA CNEL. For comparison, noise‐sensitive residential land uses are considered clearly compatible with exterior noise levels of Ͳͬ dBA CNEL. (ͭͱ)

3.3 OPERATIONAL NOISE STANDARDS
To analyze noise impacts originating from a designated fixed location or private property, such as the Project, operational source noise is typically evaluated against standards established under a City’s Municipal Code. For noise‐sensitive residential properties, the City of Coachella Municipal Code, Section ͳ.ͬͰ.ͬͯͬ (A), identifies exterior operational noise level limits for the daytime (Ͳ:ͬͬ a.m. to ͭͬ:ͬͬ p.m.) hours of ͱͱ dBA Leq and Ͱͱ dBA Leq during the nighttime (ͭͬ:ͬͬ p.m. to Ͳ:ͬͬ a.m.) hours. The City of Coachella Municipal Code noise level standards are shown in Table ͯ‐ͭ and provided in Appendix ͯ.ͭ.

3.4 CONSTRUCTION NOISE STANDARDS
To control noise impacts associated with the construction of the Project, the City has established limits to the hours of operation. Section ͳ.ͬͰ.ͬͳͬ of the City’s Municipal Code, provided in Appendix ͯ.ͭ, indicates that construction activities shall be limited from October ͭst through April ͯͬth, Monday to Friday, between the hours of Ͳ:ͬͬ a.m. and ͱ:ͯͬ p.m., and between ʹ:ͬͬ a.m. and ͱ:ͬͬ p.m. on Saturdays, Sundays, and holidays. From May ͭst through September ͯͬth, construction is limited to between ͱ:ͬͬ a.m. and ͳ:ͬͬ p.m. Monday to Friday, and between ʹ:ͬͬ a.m. and ͱ:ͬͬ p.m. on 2341

Saturdays, Sundays, and holidays. (ͭͲ) However, neither the City of Coachella Neither the General Plan nor the Municipal Code establishes numeric maximum acceptable construction source noise levels at potentially affected receivers. Therefore, a numerical construction threshold based on the Federal Transit Administration (FTA) Transit Noise and Vibration Impact Assessment Manual is used for analysis of daytime construction impacts, as discussed below.

According to the FTA, local noise ordinances are typically not very useful in evaluating construction noise. They usually relate to nuisance and hours of allowed activity, and sometimes specify limits in terms of maximum levels, but are generally not practical for assessing the impact of a construction project. Project construction noise criteria should account for the existing noise environment, the absolute noise levels during construction activities, the duration of the construction, and the adjacent land use. Due to the lack of standardized construction noise thresholds, the FTA provides guidelines that can be considered reasonable criteria for construction noise assessment. The FTA considers a daytime exterior construction noise level of ʹͬ dBA Leq as a reasonable threshold for noise‐sensitive residential land use (ͭͳ p. ͭͳ͵).

3.5 CONSTRUCTION VIBRATION STANDARDS
Construction activity can result in varying degrees of ground‐borne vibration, depending on the equipment and methods used, distance to the affected structures, and soil type. Construction vibration is generally associated with pile driving and rock blasting. Other construction equipment, such as air compressors, light trucks, hydraulic loaders, etc., generates little or no ground vibration (ͭͳ).

To analyze vibration impacts associated with the Project, vibration‐generating activities are appropriately evaluated against standards established under a City’s Municipal Code if such standards exist. The City of Coachella does not identify specific construction vibration level limits.

Therefore, for analysis purposes, the Caltrans Transportation and Construction Vibration Guidance Manual, (ͭͭ p. ͯʹ) Table ͭ͵, vibration damage is used in this noise study to assess potential temporary construction‐related impacts at adjacent building locations. The nearest noise‐sensitive buildings adjacent to the Project site can best be described as “older residential structures” with a maximum acceptable continuous vibration threshold of ͬ.ͯͬ PPV (in/sec).

3.6 AIRCRAFT NOISE
The County of Riverside is responsible for the management and development of the Airport Land Use Compatibility Plan (ALUCP) for each public use and military airport in Riverside County. Each ALUCP identifies land use and noise level compatibility due to operations at airports, as well as forecasted noise level contours based on future operations at each airport. These noise level contours and land use compatibility noise levels are used in determining whether a proposed land use is consistent with forecasted noise levels. The ALUCP for the Project site is the Jacqueline Cochran Regional Airport (JCRA) ALUCP. Exhibits ͯ‐ͮ and ͯ‐ͯ present the JCRA Compatibility Zones and the JCRA Compatibility Criteria, respectively. The Project is located beyond Zone E as shown on Exhibit ͯ‐ͮ

4 SIGNIFICANCE CRITERIA
The following significance criteria are based on currently adopted guidance provided by Appendix G of the California Environmental Quality Act (CEQA) Guidelines. (ͭ) For the purposes of this report, impacts would be potentially significant if the Project results in or causes:

A. Generation of a substantial temporary or permanent increase in ambient noise levels in the vicinity of the project in excess of standards established in the local general plan or noise ordinance, or applicable standards of other agencies?
B. Generation of excessive ground‐borne vibration or ground‐borne noise levels? C. For a project located within the vicinity of a private airstrip or an airport land use plan or, where such a plan has not been adopted, within two miles of a public airport or public use airport, would the project expose people residing or working in the project area to excessive noise levels?

4.1 NOISE LEVEL INCREASES (THRESHOLD A)
Noise level increases resulting from the Project are evaluated based on the Appendix G CEQA Guidelines. Under CEQA, consideration must be given to the magnitude of the increase, the existing baseline ambient noise levels, and the location of receivers to determine if a noise increase represents a significant adverse environmental impact. This approach recognizes that there is no single noise increase that renders the noise impact significant. (ͭʹ) This is primarily because of the wide variation in individual thresholds of annoyance and differing individual experiences with noise.

Thus, an important way of determining a person’s subjective reaction to a new noise is the comparison of it to the existing environment to which one has adapted—the so‐called ambient environment.

4.1.1 Noise Sensitive Receivers (Substantial Permanent Noise Level Increase) The Federal Interagency Committee on Noise (FICON) (ͭ͵) developed guidance to be used for the assessment of project‐generated increases in noise levels that consider the ambient noise level. The FICON recommendations are based on studies that relate aircraft noise levels to the percentage of persons highly annoyed by aircraft noise. Although the FICON recommendations were specifically developed to assess aircraft noise impacts, these recommendations are often used in environmental noise impact assessments involving the use of cumulative noise exposure metrics, such as the average‐daily noise level (CNEL) and equivalent continuous noise level (Leq). In general, the more a new noise level exceeds the previously existing ambient noise level, the less acceptable the new noise level will typically be judged.

As previously stated, the approach used in this noise study recognizes that there is no single noise increase that renders a noise impact significant, based on a ͮͬͬʹ California Court of Appeal ruling on Gray v. County of Madera. (ͭʹ) For example, if the ambient noise environment is quiet (<Ͳͬ dBA) and the new noise source greatly increases the noise levels, an impact may occur if the noise criteria may be exceeded. Therefore, for this analysis, a readily perceptible ͱ dBA or greater project‐related noise level increase is considered a significant impact when the without project noise levels are below Ͳͬ dBA. Per the FICON, in areas where the without project noise levels range from Ͳͬ to Ͳͱ dBA, a ͯ dBA barely perceptible noise level increase appears to be appropriate for most people.

When the without project noise levels already exceed Ͳͱ dBA, any increase in community noise 2345
Item 2.
ͭͲͱͱͮ‐ͬͮ NA ͮͬ COVA
louder than ͭ.ͱ dBA or greater is considered a significant impact if the noise criteria for a given land use is exceeded, since it likely contributes to an existing noise exposure exceedance.

The FICON guidance provides an established source of criteria to assess the impacts of substantial temporary or permanent increase in baseline ambient noise levels. Based on the FICON criteria, the amount to which a given noise level increase is considered acceptable is reduced when the without Project (baseline) noise levels are already shown to exceed certain land‐use specific exterior noise level criteria. The specific levels are based on typical responses to noise level increases of ͱ dBA or readily perceptible, ͯ dBA or barely perceptible, and ͭ.ͱ dBA depending on the underlying without Project noise levels for noise‐sensitive uses. These levels of increases and their perceived acceptance are consistent with guidance provided by both the Federal Highway Administration (Ͱ p. ͵) and Caltrans (ͮͬ p. ͮ_Ͱʹ).

4.1.2 Non-Transportation Noise (Substantial Permanent Noise Level Increase) The FICON criteria are also used to determine if Project‐related stationary source (operational) noise level increases are significant at off‐site receiver locations. For non‐transportation noise source activities, a substantial permanent noise level increase consists of increases of ͱ dBA or readily perceptible, ͯ dBA or barely perceptible, and ͭ.ͱ dBA, depending on the underlying ambient noise levels.

4.1.3 Construction Noise (Substantial Temporary Noise Level Increase) To control the noise‐generating construction activities, the temporary noise level increases over the existing ambient conditions must be considered under CEQA Significance Threshold A. Although noise ordinances vary across jurisdictions, many cities and counties in California, including Los Angeles, San Diego, and San Francisco, set construction noise limits between ͳͱ and ʹͬ dBA Leq and typically restrict construction activities to the daytime hours. In contrast, everyday noise regulations are more stringent because they apply to continuous, long‐term noise sources that can significantly impact the quality of life. As a result, many jurisdictions establish daytime residential noise limits around ͱͱ dBA Leq. This suggests that a reasonable ͮͬ dBA increase over the daytime noise limit can be tolerated without significant adverse effects. This is also illustrated in the adoption of many CEQA documents statewide that use an ʹͬ dBA Leq limit for assessing construction impacts while using everyday noise level limits of local noise ordinances in assessing on‐site operational impacts.

Therefore, if the Project‐related construction noise levels generate a temporary noise level increase over the existing daytime ambient noise levels more than ͮͬ dBA Leq then the Project construction noise increases will be considered a significant impact.

4.2 VIBRATION (THRESHOLD B)
As described in Section ͯ.Ͱ, the vibration impacts originating from the construction of the Project, vibration‐generating activities are appropriately evaluated using standards established by the Caltrans Transportation and Construction Vibration Guidance Manual, Table ͭ͵. The Caltrans’ vibration thresholds for building damage are used in this noise study to assess potential operational and temporary construction‐related impacts at adjacent building locations. A maximum acceptable continuous vibration threshold of ͬ.ͯͬ PPV (in/sec) is used to describe the nearest residential buildings adjacent to the Project site.

4.3 CEQAGUIDELINES NOT FURTHER ANALYZED (THRESHOLD C)
CEQA Noise Threshold C applies when there are nearby public and private airports and/or airstrips and focuses on land use compatibility of the Project to nearby airports and airstrips. The closest major airport is the San Gabriel Valley Airport (SGVA), located ͭ.ͱ miles northeast of the Project site.

As shown in section ͯ, the Project site is beyond the Ͳͱ dBA CNEL noise level contour and would not be exposed to excessive noise levels from airport operations. Therefore, impacts are considered less than significant, and no further noise analysis is conducted in relation to Appendix G to the CEQA Guidelines, Noise Threshold C.

4.4 SIGNIFICANCE CRITERIA SUMMARY
Noise impacts shall be considered significant if any of the following occur as a direct result of the proposed development. Table Ͱ‐ͭ shows the significance criteria summary matrix that includes the allowable criteria used to identify potentially significant incremental noise level increases.

5 EXISTING NOISE LEVEL MEASUREMENTS
To assess the existing noise level environment, ͮͰ‐hour noise level measurements were taken at five locations in the Project study area. The receiver locations were selected to describe and document the existing noise environment within the Project study area. Exhibit ͱ‐ͭ provides the boundaries of the Project study area and the noise level measurement locations. To fully describe the existing noise conditions, long‐term noise level measurements were collected by Urban Crossroads, Inc. on Friday, July ͮͱ, ͮͬͮͱ. Appendix ͱ.ͭ includes study area photos.

5.1 MEASUREMENT PROCEDURE AND CRITERIA
To describe the existing noise environment, the hourly noise levels were measured during typical weekday conditions over a ͮͰ‐hour period. By collecting individual hourly noise level measurements, it is possible to describe the equivalent daytime and nighttime hourly noise levels.

The long‐term noise readings were recorded using Piccolo Type ͮ integrating sound level meter and dataloggers. The Piccolo sound level meters were calibrated using a Larson‐Davis calibrator, Model CAL ͭͱͬ. All noise meters were programmed in "slow" mode to record noise levels in "A" weighted form. The sound level meters and microphones were equipped with a windscreen during all measurements. All noise level measurement equipment satisfies the American National Standards Institute (ANSI) standard specifications for sound level meters ANSI Sͭ.Ͱ‐ͮͬͭͰ/IEC ͲͭͲͳͮ‐ͭ:ͮͬͭͯ. (ͮͭ)

5.2 NOISE MEASUREMENT LOCATIONS
The long‐term noise level measurements were positioned as close to the nearest sensitive receiver locations as possible to assess the existing equivalent hourly noise levels surrounding the Project site. Both Caltrans and the FTA recognize that it is not reasonable to collect noise level measurements that can fully represent every part of a private yard, patio, deck, or balcony normally used for human activity when estimating impacts for new development projects. This is demonstrated in the Caltrans general site location guidelines, which indicate that sites must be free of noise contamination by sources other than sources of interest. Avoid sites located near sources such as barking dogs, lawnmowers, pool pumps, and air conditioners unless it is the express intent of the analyst to measure these sources. (ͮ) Further, FTA guidance states, that it is not necessary nor recommended that existing noise exposure be determined by measuring at every noise‐sensitive location in the project area. Rather, the recommended approach is to characterize the noise environment for clusters of sites based on measurements or estimates at representative locations in the community. (ʹ)
Based on recommendations of Caltrans and the FTA, it is not necessary to collect measurements at each individual building or residence because each receiver measurement represents a group of buildings that share acoustical equivalence. (ʹ) In other words, the area represented by the receiver shares similar shielding, terrain, and geometric relationship to the reference noise source. Receivers represent a location of noise sensitive areas and are used to estimate the future noise level impacts. 2348

Collecting noise level measurements at the nearby sensitive receiver locations allows for a comparison of the before‐and‐after Project noise levels and is necessary to assess potential noise increase due to the Project’s contribution to ambient noise levels. This approach is necessary to calculate the temporary or permanent increase in ambient noise levels as required by the CEQA Guidelines Environmental Checklist.

5.3 NOISE MEASUREMENT RESULTS
The noise measurements presented below focus on the equivalent or the hourly energy average sound levels (Leq) to describe the existing ambient conditions. Table ͱ‐ͭ provides the (energy average) noise levels used to describe the hourly daytime (ͳ:ͬͬ a.m. to ͭͬ:ͬͬ p.m.) and nighttime (ͭͬ:ͬͬ p.m. to ͳ:ͬͬ a.m.) noise levels at each noise level measurement location. The equivalent sound level (Leq) represents a steady‐state sound level containing the same total energy as a time‐ varying signal over a given sample period. The daytime and nighttime equivalent noise levels represent the average of all hourly noise levels observed during these time periods expressed as a single number.

6 OFF-SITE TRANSPORTATION NOISE ANALYSIS
The Project is anticipated to generate a maximum of ͮ,ͭͰͰ weekday trips per day. The Project would access Calhoun Street, Van Buren Street, and Avenue ͱͮ. Approximately ͯͬ percent of the traffic is expected on Van Buren Street and Avenue ͱͮ, with the remaining Ͱͬ percent using Calhoun Street.

Based on the City of Coachella traffic counts on these roads: Calhoun Street has an average daily traffic (ADT) volume of ͯ,ʹ͵ͯ, Van Buren Street has an ADT volume of ͯ,ͳ͵͵, and Avenue ͱͮ has an ADT volume of ʹ,ͯͭͲ. To generate a ͯ dBA increase in traffic noise would generally require a substantial increase in truck traffic relative to the overall mix of vehicles, or a doubling of traffic volumes. The Project would not result in the generation of substantial truck trips, and the increase in daily traffic volumes is not expected to generate a perceptible noise level increase (i.e., less than ͯ dBA CNEL) at sensitive land uses along affected roadways. Therefore, due to the low traffic volumes generated by the Project, the off‐site traffic noise levels generated by the Project are considered less than significant.

7 RECEIVER LOCATIONS
To assess the potential for long‐term operational and short‐term construction noise impacts, the following receiver locations, as shown in Exhibit ͳ‐ͭ, were identified as representative locations for analysis. The selection of receiver locations is based on FHWA guidelines and is consistent with additional guidance provided by Caltrans and the FTA, as previously described in Section ͱ.ͮ.

Sensitive receivers are generally defined as locations where people reside or where the presence of unwanted sound could otherwise adversely affect the use of the land. Noise‐sensitive land uses are generally considered to include schools, hospitals, single‐family dwellings, mobile home parks, churches, libraries, and recreation areas. Moderately noise‐sensitive land uses typically include multi‐family dwellings, hotels, motels, dormitories, outpatient clinics, cemeteries, golf courses, country clubs, athletic/tennis clubs, and equestrian clubs. Land uses that are considered relatively insensitive to noise include business, commercial, and professional developments. Land uses that are typically not affected by noise include: industrial, manufacturing, utilities, agriculture, undeveloped land, parking lots, warehousing, liquid and solid waste facilities, salvage yards, and transit terminals.

To describe the potential off‐site Project noise levels, five receiver locations in the vicinity of the Project site were identified. Other sensitive land uses in the Project study area that are located at greater distances than those identified in this noise study will experience lower noise levels than those presented in this report due to the additional attenuation from distance and the shielding of intervening structures. Distance is measured in a straight line from the Project boundary to each receiver location.

8 OPERATIONAL NOISE ANALYSIS
This section analyzes the potential operational noise impacts at the nearby receiver locations, identified in Section ͳ, resulting from the Project’s operation. Exhibit ʹ‐ͭ identifies the noise source locations used to assess the equivalent Leq operational noise levels

8.1 OPERATIONAL NOISE SOURCES
This operational noise analysis is intended to describe noise level impacts associated with the expected typical residential activities at the Project site. The operational noise sources of concern would be the ground mounted air conditioning units associated with each dwelling unit are evaluated against standards established in the City of Coachella Municipal Code, Section ͳ.ͬͰ.ͬͳͬ, and the relative increase in noise levels at each existing sensitive receiver.

8.2 REFERENCE NOISE LEVELS
To estimate the Project operational noise impacts, reference noise level measurements were collected from similar types of activities or equipment to represent the noise levels expected with the development of the Project. This section provides a detailed description of the reference noise level measurements shown in Table ʹ‐ͭ used to estimate the Project operational noise impacts.

8.2.1 Air Conditioning Units
Individual Units
To assess the noise levels created by the air conditioning units, reference noise levels were taken from equipment specifications for a ͮ‐ to ͱ‐ton residential packaged air conditioning unit (Carrier ͱͬVR‐A). The manufacturer's specifications are included in Appendix ʹ.ͭ. At a uniform reference distance of ͱͬ feet, the units would generate a reference noise level of ͰͰ.Ͱ dBA Leq. The air conditioning units were modeled ͯ feet above the ground level, operating Ͱͱ minutes per hour during the daytime and nighttime, which represents the typical maximum operating time for properly sized AC systems.

Commercial Units
The noise level measurements describe a single mechanical rooftop air conditioning unit. The reference noise level represents a Lennox SCAͭͮͬ series ͭͬ‐ton model packaged air conditioning unit. At the uniform reference distance of ͱͬ feet, the reference noise level is ͱ͵.ͮ dBA Leq. The air conditioning units were modeled ͱ feet above the ground level, operating Ͱͱ minutes per hour during the daytime and nighttime, which represents the typical maximum operating time for properly sized AC systems.

Pickleball court activity noise levels include the constant talk of the players, the “pop” sound of rackets hitting pickle balls, metal gates closing, and background park noise sources, including people talking. Noise associated with pickleball court activities is expected to occur for the entire hour (Ͳͬ minutes).

8.2.7 Tennis Court Activity
To describe the noise levels associated with tennis court activities, Urban Crossroads collected a reference noise level measurement. The measured reference noise level at the uniform ͱͬ‐foot reference distance is Ͱ͵.Ͳ dBA L₅₀ for tennis court activity. The tennis court activity noise levels include an instructor and student playing tennis, the instructor giving constant verbal feedback, the sound of rackets hitting tennis balls, metal tennis court gates closing, and background park noise sources, including people talking. Noise associated with tennis court activities is expected to occur for the entire hour (Ͳͬ minutes).

8.3 CADNAANOISE PREDICTION MODEL
To fully describe the exterior operational noise levels from the Project, Urban Crossroads, Inc. developed a noise prediction model using the CadnaA (Computer Aided Noise Abatement) computer program. CadnaA can analyze multiple types of noise sources using the spatially accurate Project site plan, georeferenced Nearmap aerial imagery, topography, buildings, and barriers in its calculations to predict outdoor noise levels. Using the ISO ͵Ͳͭͯ‐ͮ protocol, CadnaA will calculate the distance from each noise source to the noise receiver locations, using the ground absorption, distance, and barrier/building attenuation inputs to provide a summary of the noise level at each receiver and the partial noise level contributions by noise source.

Consistent with the ISO ͵Ͳͭͯ‐ͮ protocol, the CadnaA noise prediction model relies on the reference sound power level (Lw) to describe individual noise sources. While sound pressure levels (e.g., Leq) quantify in decibels the intensity of given sound sources at a reference distance, sound power levels (Lw) are connected to the sound source and are independent of distance. Sound pressure levels vary substantially with distance from the source and diminish because of intervening obstacles and barriers, air absorption, wind, and other factors. Sound power is the acoustical energy emitted by the sound source and is an absolute value that is not affected by the environment. The operational noise level calculations provided in this noise study account for the distance attenuation provided due to geometric spreading, when sound from a localized stationary source (i.e., a point source) propagates uniformly outward in a spherical pattern. A default ground attenuation factor of ͬ.ͱ was 2358

used in the noise analysis to account for mixed ground representing a combination of hard and soft surfaces. Appendix ʹ.ͮ includes the detailed noise dBA Leq model inputs used to estimate the Project operational noise levels presented in this section.

8.4 PROJECT OPERATIONAL NOISE LEVELS
Using the reference noise levels to represent the Project operations that include ground mounted air conditioning units, Urban Crossroads, Inc. calculated the operational source noise levels that are expected to be generated at the Project site and the Project‐related noise level increases that would be experienced at each of the sensitive receiver locations. Table ʹ‐ͮ shows the Project operational noise levels during the daytime hours of ͳ:ͬͬ a.m. to ͭͬ:ͬͬ p.m. The daytime hourly noise levels at the off‐site receiver locations are expected to range from ͰͰ.Ͱ to Ͱ͵.͵ dBA Leq.

8.5 PROJECT OPERATIONAL NOISE LEVEL COMPLIANCE
To demonstrate compliance with local noise regulations, the unmitigated Project‐only operational noise levels are evaluated against exterior noise level thresholds based on the City of Coachella exterior noise level standards at nearby receiver locations. Table ʹ‐Ͱ shows that the mitigated operational noise levels associated with the Project will not exceed the City of Coachella daytime and nighttime exterior noise level standards at the existing nearby noise‐sensitive receiver locations.

Therefore, the mitigated operational noise impacts are considered less than significant at the nearby noise‐sensitive receiver locations.

"Daytime" = 7:00 a.m. - 10:00 p.m.; "Nighttime" = 10:00 p.m. - 7:00 a.m.

8.6 PROJECT OPERATIONAL NOISE LEVEL INCREASES
To describe the Project operational noise level increases, the Project operational noise levels are combined with the existing ambient noise level measurements for the nearby receiver locations that may be potentially impacted by Project operational noise sources. Since the units used to measure noise, decibels (dB), are logarithmic units, the Project‐operational and existing ambient noise levels cannot be combined using standard arithmetic equations. (ͮ) Instead, they must be logarithmically added using the following base equation:

SPLTotal = ͭͬlogͭͬ[ͭͬSPLͭ/ͭͬ + ͭͬSPLͮ/ͭͬ + … ͭͬSPLn/ͭͬ] where “SPLͭ,” “SPLͮ,” etc. are equal to the sound pressure levels being combined, or in this case, the Project‐operational and existing ambient noise levels. The difference between the combined Project and ambient noise levels describes the Project noise level increases over the existing ambient noise environment. Noise levels that would be experienced at receiver locations when Project‐ source noise is added to the daytime and nighttime ambient conditions are presented in Tables ʹ‐ͱ and ʹ‐Ͳ, respectively. As indicated in Table ʹ‐ͱ, the Project will generate daytime operational noise increases ranging from ͬ.ͬ to ͬ.ͳ dBA Leq at the nearest receiver locations. Table ʹ‐Ͳ shows that the Project will generate nighttime operational noise level increases ranging from ͬ.ͬ to ͮ.Ͱ dBA Leq at the nearest receiver locations. Project‐related operational noise level increases would not exceed the operational noise level increase significance criteria presented in Table Ͱ‐ͭ. Therefore, Project‐ 2360

related operational noise level increases at the sensitive receiver locations will be less than significant.

9 CONSTRUCTION IMPACTS
This section analyzes potential impacts resulting from the short‐term construction activities associated with the development of the Project. Exhibit ͵‐ͭ shows the on‐site construction noise source activity in relation to the nearest sensitive receiver locations previously described in Section ͳ. According to Section ͳ.ͬͰ.ͬͳͬ of the Municipal Code, between October ͭst and April ͯͬth, construction, erection, demolition, alteration, repair, addition to or improvement of any building, structure, road, or improvement to realty is prohibited Monday through Friday, Ͳ:ͬͬ a.m. to ͱ:ͯͬ p.m., Saturday, ʹ:ͬͬ a.m. to ͱ:ͬͬ p.m., Sunday, ʹ:ͬͬ a.m. to ͱ:ͬͬ p.m., and on Holidays, ʹ:ͬͬ a.m. to ͱ:ͬͬ p.m. Also, construction, erection, demolition, alteration, repair, addition to or improvement of any building, structure, road, or improvement to realty is prohibited between May ͭst and September ͯͬth, Monday through Friday: ͱ:ͬͬ a.m. to ͳ:ͬͬ p.m., Saturday: ʹ:ͬͬ a.m. to ͱ:ͬͬ p.m., Sunday: ʹ:ͬͬ a.m. to ͱ:ͬͬ p.m., and Holidays: ʹ:ͬͬ a.m. to ͱ:ͬͬ p.m. (ͮͮ)

9.1 CONSTRUCTION NOISE LEVELS
The FTA Transit Noise and Vibration Impact Assessment Manual recognizes that construction projects are accomplished in several different stages and outlines the procedures for assessing noise impacts during construction. Each stage has a specific equipment mix, depending on the work to be completed during that stage. As a result of the equipment mix, each stage has its own noise characteristics; some stages have higher continuous noise levels than others, and some have higher impact noise levels than others. The Project construction activities are expected to occur in the following stages:
• Site Preparation
• Grading
• Building Construction
• Paving
• Architectural Coating

9.2 CONSTRUCTION REFERENCE NOISE LEVELS
To describe construction noise activities, this construction noise analysis was prepared using reference construction equipment noise levels from the Federal Highway Administration (FHWA) published the Roadway Construction Noise Model (RCNM), which includes a national database of construction equipment reference noise emission levels. (ͮͯ) The RCNM equipment database provides a comprehensive list of the noise‐generating characteristics of specific types of construction equipment. In addition, the database provides an acoustical usage factor to estimate the fraction of time each piece of construction equipment is operating at full power (i.e., its loudest condition) during a construction operation. According to the EPA, FTA, and FHWA, the overall construction noise level is governed primarily by the noisiest pieces of equipment. The quieter pieces do not affect the overall level, but they do reduce the magnitude of the fluctuations in the noise level.

Therefore, a rough estimate of the noise level need only include the noisiest pieces of equipment expected at the site. (ͮͰ) (ʹ) (ͮͱ) Consistent with FHWA and FTA guidance for detailed construction noise assessment, Table ͵‐ͭ presents the combined noise levels for the loudest construction activities expected for each stage, assuming all equipment operates simultaneously. 2363

9.3 CONSTRUCTION NOISE ANALYSIS
Construction projects involve various stages, and activities frequently shift from one location to another. For example, during site preparation and grading, noise‐generating activities may concentrate in an area for a short period to remove an obstruction, while the majority of the grading involves the equipment moving back and forth in a predictable pattern throughout the site; building construction and foundation work generally concentrate near the building footprint, while paving generally involves a predictable pattern of movement throughout the site. Therefore, construction activities are best evaluated as multiple moving point sources within the construction area since the speed and power of the equipment vary, and the equipment constantly changes position in terms of its distance and direction relative to the receivers. (ʹ) (ͮͲ) Using the reference construction equipment noise levels and the CadnaA noise prediction model, calculations of the Project construction noise level impacts by phase at the nearby sensitive receiver locations were completed.

To account for the dynamic nature of construction activities, the CadnaA construction noise analysis evaluates the noise source activities as multiple moving point sources, or construction crews, within the limits of construction. Construction impacts are based on the loudest activity and the highest noise level calculated at each receiver location. As shown in Table ͵‐ͮ, the highest construction noise levels are expected to range from ͱͰ.Ͳ to Ͳͯ.Ͳ dBA Leq at the nearby receiver locations. Appendix ͵.ͭ includes the detailed CadnaA construction noise model inputs. 2365

9.4 PROJECT SITE CONSTRUCTION NOISE LEVEL COMPLIANCE
To evaluate whether the Project will generate potentially significant short‐term noise levels at the nearest receiver locations, a construction‐related daytime noise level threshold of ʹͬ dBA Leq is used as a reasonable threshold to assess the daytime construction noise level impacts. The construction noise analysis shows that the nearest receiver locations will not exceed the reasonable daytime ʹͬ dBA Leq significance threshold during Project construction activities at any receiver shown in Exhibit ͳ‐ͭ. Therefore, the noise impacts due to Project construction noise are considered less than significant.

9.5 TEMPORARY CONSTRUCTION NOISE LEVEL INCREASES
To describe the temporary Project construction noise level contributions to the existing ambient noise environment, the Project construction noise levels were combined with the existing ambient noise level measurements at the nearest off‐site receiver locations. The difference between the combined Project‐construction and ambient noise levels is used to describe the construction noise level contributions. Temporary noise level increases that would be experienced at sensitive receiver 2366

locations when Project construction‐source noise is added to the ambient daytime conditions are presented in Table ͵‐Ͱ. A temporary noise level increase of ͮͬ dBA is considered a significant impact based on the substantial noise level increase criteria, which is used to assess the Project‐construction noise level increases.

As indicated in Table ͵‐Ͱ, the Project construction will contribute to noise level increases ranging from ͬ.ͭ to ͮ.ͱ dBA Leq during the daytime hours at the nearest receiver locations. The unmitigated construction noise analysis shows that the nearest receiver locations will not exceed the ͮͬ dBA Leq noise level increase significance threshold during Project construction activities. The temporary construction noise level increase analysis shows that the noise impacts due to the Project construction noise are considered less than significant.

9.6 CONSTRUCTION VIBRATION ANALYSIS
Construction activity can result in varying degrees of ground vibration, depending on the equipment and methods employed. The operation of construction equipment causes ground vibrations that spread through the ground and diminish in strength with distance. Ground vibration levels associated with various types of construction equipment are summarized in Table ͵‐ͱ. Based on the representative vibration levels presented for various construction equipment types, it is possible to estimate the potential for human response (annoyance) and building damage using the following vibration assessment methods defined by Caltrans. To describe the vibration impacts, Caltrans provides the following equation: PPVequip = PPVref x (ͮͱ/D)ͭ.ͱ 2367

Federal Transit Administration, Transit Noise and Vibration Impact Assessment Manual Using the vibration source level of construction equipment provided in Table ͵‐ͱ and the construction vibration assessment methodology published by the FTA, it is possible to estimate the Project vibration impacts. Table ͵‐Ͳ presents the expected Project‐related vibration levels at the nearby receiver locations. At distances ranging from ͯ to ͮͬͳ feet from Project construction activities, construction vibration velocity levels are estimated to range from less than ͬ.ͬͭ to ͱ.ͬͱ PPV in/sec. Based on the maximum acceptable continuous vibration threshold of ͬ.ͯͬ PPV (in/sec), the typical Project construction vibration levels will not exceed the vibration thresholds at any receivers. Therefore, the Project‐related vibration impacts are considered less than significant during typical construction activities at the Project site.

It should be noted that vibration levels at the site of the closest sensitive receiver are unlikely to be sustained during the entire construction period, but will occur only during the times that heavy construction equipment is operating adjacent to the Project site perimeter. Moreover, construction at the Project site will be restricted to the daytime hours, consistent with City of Coachella requirements, eliminating potential vibration impacts during the sensitive evening and nighttime hours.

The city of Coachella is required to make multiple responses to such unruly gatherings in order to restore and maintain the peace and protect public safety. Such gatherings are a burden on scarce city resources and can result in police responses to regular and emergency calls being delayed and police protection to the rest of the city being reduced.

In order to discourage the occurrence of repeated loud and unruly gatherings, the persons responsible for the public nuisance created by these gatherings should be fined. (Ord. No. 1023, § 1, 11-17-10; Ord. No. 1025, 11-17-10)

Where the gathering took place in the common area of a building owned by a housing cooperative, only the members of the cooperative owning units in the building where the gathering took place shall be deemed the owners of the property for purposes of this subsection.

Nothing in this section shall be construed to impose liability on the resident or owners of the premises or sponsor of the gathering, for the conduct of persons who are present without the express or implied consent of the resident or sponsor, as long as the resident and sponsor have taken all steps reasonably necessary to exclude such uninvited participants from the premises. Where an invited guest engages in conduct which the sponsor or resident could not reasonably foresee and the conduct is an isolated instance of a guest at the event violating the law which the sponsor is unable to reasonably control without the intervention of the police, the unlawful conduct of the individual guest shall not be attributable to the sponsor, owner, or resident for the purposes of determining whether the event constitutes a public nuisance under this section.

There shall be no liability for civil penalties under this chapter for a subsequent intervention during the same day or night as the prior intervention, unless a reasonable time has been provided to abate the public nuisance, taking into account the size of the gathering, the time of day, and other relevant factors.

There shall be no liability for civil penalties under this chapter for a second response during the same day or night as the first response when a person who would otherwise be liable under subsection (A) seeks assistance from the police department to abate a public nuisance under this chapter, and the person cooperates fully with the police while taking reasonable action to abate the public nuisance.

If the city is required to intervene at a gathering constituting a public nuisance on the same premises more than once in any 60-day period, excluding a second intervention during the same day or night as the first intervention, the 60-day period shall be extended by another sixty (60) days from the date of the second intervention.

The actual cost to the city of law enforcement services incurred as a result of a subsequent response;
The actual cost of any medical treatment required by a police officer for injuries sustained during a subsequent response; and

The remedies set forth in this chapter shall be in addition to any other penalties imposed by law for particular violations of law committed during the course of an event which is a public nuisance under this chapter, provided however, that if the only violation of law which constituted the public nuisance under this chapter is excessive noise, the remedies provided under this chapter shall be exclusive of any other remedies provided by law to the city for such excessive noise.

The city shall bill all persons liable for subsequent response fees by mail by sending a letter in substantially the form attached hereto as Exhibit "B." Payment of the fees shall be due within thirty (30) days of the date the bill is deposited in the mail.

This is the (second/third/fourth, etc.) such public nuisance at this property within the last 60 days, and thus, a fee of ________ is imposed on you. If you fail to remit this fine to the City of Coachella by (30 days from the date of this notification) you will be liable for an additional $100 penalty, plus interest. The payment should be remitted to the address listed below. Your liability is based on the fact that you were:

FEATURES/BENEFITS
One--piece heat pump unit with optional electric heater, low sound levels, easy installation, low maintenance, and dependable performance.

Puron Environmentally Sound Refrigerant is Carrier’s unique refrigerant designed to help protect the environment. Puron is an HFC refrigerant which does not contain chlorine that can harm the ozone layer. Puron refrigerant is in service in millions of systems proving highly reliable, environmentally sound performance.

Easy Installation
Factory--assembled package is a compact, fully self--contained, electric cooling unit that is prewired, pre--piped, and pre--charged for minimum installation expense. These units are available in a variety of standard cooling sizes with voltage options to meet residential and light commercial requirements. Units are lightweight and install easily on a rooftop or at ground level. The high tech composite base eliminates rust problems associated with ground level applications.

Innovative Unit Base Design
On the inside a high--tech composite material will not rust and incorporates a sloped drain pan which improves drainage and helps inhibit mold, algae and bacterial growth. On the outside metal base rails provide added stability as well as easier handling and rigging.

Convertible duct configuration
Unit is designed for use in either downflow or horizontal applications. Each unit is converted from horizontal to downflow and includes horizontal duct covers. Downflow operation is provided in the field to allow vertical ductwork connections. The basepan seals on the bottom openings to ensure a positive seal in the vertical airflow mode.

Efficient operation High--efficiency design offers SEER (Seasonal Energy Efficiency Ratios) of up to 15.5 and HSPF of

8.5. (See page 4.)
Durable, dependable components
Scroll Compressors have 2 stages of cooling/heating and are designed for high efficiency. Each compressor is hermetically sealed against contamination to help promote longer life and dependable operation. Each compressor also has vibration isolation to provide quieter operation. All compressors have internal high pressure and overcurrent protection.

Multi--speed ECM Blower Motor is standard on all 50VR--A.

Direct--drive PSC (Permanent Split Capacitor) condenser--fan motors are designed to help reduce energy consumption and provide for cooing operation down to 40_F (4.4_C) outdoor temperature. Motormasterr II low ambient kit is available as a field--installed accessory.

Thermostatic Expansion Valve -- A hard shutoff, balance port TXV maintains a constant superheat at the evaporator exit (cooling cycle) resulting in higher overall system efficiency.

Refrigerant system is designed to provide dependability. Liquid filter driers are used to promote clean, unrestricted operation. Each unit leaves the factory with a full refrigerant charge. Refrigerant service connections make checking operating pressures easier.

High and Low Pressure Switches provide added reliability for the compressor.

Indoor and Outdoor coils are computer--designed for optimum heat transfer and efficiency. The indoor coil is fabricated from copper tube and aluminum fins and is located inside the unit for protection against damage. The outdoor coil is internally mounted on the top tier of the unit.

Low sound ratings ensure a quiet indoor and outdoor
environment with sound ratings as low as 71dBA. (See Page 4.) Easy to service cabinets provide easy 3 panel accessibility to serviceable components during maintenance and installation. The basepan with integrated drain pan provides easy ground level installation with a mounting pad. A nesting feature ensures a positive basepan to roof curb seal when the unit is roof mounted. A convenient 3/4--in. (19.05 mm) wide perimeter flange makes frame mounting on a rooftop easy.

2 Dehumidification Feature
This unit has independent fan speeds for low stage cooling and high stage cooling. In addition, 208/230 VAC models have the field--selectable capability to run an enhanced dehumidification (’DHUM’) speed on high stage cooling (as low as 320CFM per ton). Coupled with the improved dehumidification associated with low stage cooling, the DHUM speed allows for a complete dehumidification solution independent of cooling stage. The dehumidification control must open the control circuit on humidity rise above the dehumidification set point.

NOTE: The enhanced dehumidification feature on high stage cooling does not support use of an economizer.

Standard horizontal metal duct covers with insulation come with the unit and cover the horizontal duct openings. These can be left in place if the units are converted to downflow.

Cabinets are constructed of heavyduty, phosphated, zinc--coated prepainted steel capable of withstanding 500 hours in salt spray.

Interior surfaces of the evaporator/electric heater compartment are insulated with foil--faced insulation, which keeps the conditioned air from being affected by the outdoor ambient temperature and provides improved indoor air quality. (Conforms to American Society of Heating, Refrigeration and Air Conditioning Engineers No. 62P.) The sloped drain pan minimizes standing water in the drain. An external drain is provided.

Short--Cycling protection for the compressor is incorporated into our defrost control board ensuring a five minute delay (+/--2 minutes) before restarting compressor after shutdown for any reason.

10 SELECTION PROCEDURE (WITH EXAMPLE)

1. Determine cooling and heating requirements at
design conditions:

Given:

Required Cooling Capacity (TC) 34,000 Btuh ..........

Sensible Heat Capacity (SHC) 24,000 Btuh ............

Required Heating Capacity 12,500 Btuh ...............

Condenser Entering Air Temperature 95 ........ F(35C) Indoor--Air Temperature 80 ............. F (26C) edb
67F (19C) ewb
Evaporator Air Quantity .................. 1200 CFM
External Static Pressure 0.20 IN. W.C. .................

Electrical Characteristics 230--1--60 ...................

2. Select unit based on required cooling capacity.

Enter Net Cooling Capacities table at condenser entering temperature of 95F (35C), indoor air entering at 1200 cfm and 67F (19C) ewb (entering wet bulb). The unit will provide a total capacity of 34,200 Btuh and a SHC of 24,500 Btuh.

3. Select electric heat.

The required heating capacity is 15,000 Btuh.

Determine additional electric heat capacity in kW.
15,000 Btuh = 4.4kW of heat required
3,414 Btuh/kW
Enter the electric Heater Packages table for 208/240, single--phase, 50VR--A36 unit. The 5 kW heater at 240v most closely satisfies the heating required. To calculate kW at the 208v, multiply the heater kW by multiplication factor 0.75 found in the Wattage Multiplication Factors table.
5 kW x 0.75 = 3.75 kW

3.75 kW x 3414 = 12802.50 Btuh

4. Determine fan speed and power requirements at
design conditions.

Before entering the air delivery tables, calculate the total static pressure required. From the given example, the Wet Coil Pressure Drop Table, and the Filter Pressure Drop Table:

External Static Pressure 0.200 IN. W.C.

Filter 0.000 IN. W.C.

Wet Coil Pressure Drop 0.130 IN. W.C.

Total Static Pressure 0.330 IN. W.C.

Enter the table for Wet Coil Air Delivery—horizontal discharge, 230. At 0.33 IN. W.C. ESP (external static pressure) and medium speed, the fan will deliver 1293 cfm. Adjusting for 208v, the motor delivers 114 cfm (deduct 10%).

5. Select unit that corresponds to power source
available.

The Electrical Data Table shows that the unit is designed to operate at 208--1--60.
