the necessary noise mitigation measures, if any, for the Surf Farm (“Project”). The Project site is a 15.38-acre site located at 3100 Irvine Avenue in Newport Beach in Newport Beach. The Project would develop a develop a 5-acre wave lagoon with 3 warming pools and one spa, and a 50,170 square-foot (SF) three-story clubhouse, with 18,137 SF of basement storage and restroom, a 9,432 SF athlete accommodation building with 1,624 SF of ancillary restroom and storage space, totaling a gross floor area of 79,534 SF. The Project also includes 351 parking stalls, many of which are under PV solar canopies. Solar panels would also be installed on the roofs of both proposed buildings. The results of this Surf Farm Noise Analysis are summarized below based on the significance criteria in Section 4 of this report, consistent with Appendix G of the California Environmental Quality Act (CEQA) Guidelines. (1) Table ES-1 shows the findings of significance for each potential noise and/or vibration impact under CEQA.

Surf Farm Noise Analysis 16241-07_NA.docx 3 1 INTRODUCTION This noise analysis has been completed to determine the noise impacts associated with the development of the Surf Farm (“Project”). This Noise Analysis briefly describes the Project, provides information regarding noise fundamentals, describes the local regulatory setting, and provides the study methods and procedures for an analysis of the potential Project-related long- term operational noise and short-term construction noise and vibration impacts. 1.1 SITE LOCATION The Project site is a 15.38-acre located at 3100 Irvine Avenue in Newport Beach, as shown in Exhibit 1-A. To the west and south of the site are residential uses, to the east are commercial uses, and to the north is the Newport Beach Golf Course. 1.2 PROJECT DESCRIPTION The Project would develop a 5-acre wave lagoon with three warming pools and one spa, a 50,170 square foot (SF) three-story clubhouse with 18,137 SF of basement storage and restroom, a 9,218 SF athlete accommodation building with 1,624 SF of ancillary restroom and storage space, totaling a gross floor area of 79,534 SF. The Project also includes two parking lots with 351 parking stalls, many of which are covered with solar canopies. The primary noise sources of concern will include: roof-top air conditioning units, trash enclosure activity, loading activity, surf lagoon activity, satellite speakers, main announcement speakers, wave machine activity, water heating equipment, spectator activity, and parking lot vehicle movements. The Project sound system will be designed to exceed on-site ambient noise levels by no more than 10 decibels. This ensures that announcements are audible and understandable on-site, ambient music near spectator areas and around surf lagoon is audible, and noise pollution to surrounding areas is minimized. The hours of music will be limited between the hours of 7:00 a.m. and 10:00 p.m. Surf Farm Noise Analysis 16241-07_NA.docx 4 EXHIBIT 1-A: LOCATION MAP :dtoSqu&(t nd p Prl!'!S,d ioOf'IY« Te Winkle i Pork _ / 5A -8 Santa Ana Country Club Upper Newport BoyNowre Preserve Surf Farm Noise Analysis 16241-07_NA.docx 5 EXHIBIT 1-B: SITE PLAN Surf Farm Noise Analysis 16241-07_NA.docx 6 This page was intentionally left blank. Surf Farm Noise Analysis 16241-07_NA.docx 7 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 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 which are audible to the human ear. Exhibit 2-A presents a summary of the typical noise levels and their subjective loudness and effects, which are described in more detail below. EXHIBIT 2-A: 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 10, the logarithmic scale. The scale for measuring intensity is the decibel scale. Each interval of 10 decibels indicates a sound energy ten times greater than before, which is perceived by the human ear as being roughly twice as loud. (2) The most common sounds vary between 40 dBA (very quiet) to 100 dBA (very loud). Normal conversation at three feet is roughly at 60 dBA, while loud jet engine noises equate to 110 dBA at approximately 100 feet, which can cause serious discomfort. (3) Another important aspect of noise is the duration of the sound and the way it is described and distributed in time.

The most used figure 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 24-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 24 hours. The time-of-day corrections require the addition of 5 decibels to dBA Leq sound levels in the evening from 7:00 p.m. to 10:00 p.m., and the addition of 10 decibels to dBA Leq sound levels at night between 10:00 p.m. and 7:00 a.m. These additions are made to account for the noise-sensitive time periods during the evening and night hours when sound appears louder. CNEL does not represent the actual sound level heard at any time, but rather represents the total sound exposure. The City of Newport Beach relies on the 24-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 6 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 3 dB for each doubling of distance from a line source. (2) 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 200 feet. 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 Surf Farm Noise Analysis 16241-07_NA.docx 9 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 1.5 dB per doubling of distance is normally assumed. When added to the cylindrical spreading, the excess ground attenuation results in an overall drop-off rate of 4.5 dB per doubling of distance from a line source. (4) 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 500 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) 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 nearest residents. However, for vegetation to provide a substantial, or even noticeable, noise reduction, the vegetation area must be at least 15 feet in height, 100 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 5 dBA of noise reduction. The FHWA does not consider the planting of vegetation to be a noise abatement measure. (4) 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 up to 10 to 15 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 be high enough and long enough to block the path of the noise source. (4) 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 are commercial or industrial developments and related activities. As ambient noise levels affect the perceived amenity or Surf Farm Noise Analysis 16241-07_NA.docx 10 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 governments 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 sensitive land uses are minimized. (5) 2.7 COMMUNITY RESPONSE TO NOISE Community responses to noise may range from registering a complaint by telephone or letter, to initiating court action, depending upon everyone’s susceptibility to noise and personal attitudes about noise. Several factors are related to the level of community annoyance including:  Fear associated with noise-producing activities;  Socio-economic status and educational level;  Perception that those affected are being unfairly treated;  Attitudes regarding the usefulness of the noise-producing activity;  Belief that the noise source can be controlled. Approximately ten 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 will occur. Twenty-five percent of the population will not complain even in very severe noise environments. Thus, a variety of reactions can be expected from people exposed to any given noise environment. (6) Surveys have shown that about ten percent of the people exposed to traffic noise of 60 dBA will report being highly annoyed with the noise, and each increase of one dBA is associated with approximately two percent more people being highly annoyed. When traffic noise exceeds 60 dBA or aircraft noise exceeds 55 dBA, people may begin to complain. (6) 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 in Exhibit 2-B. A change of 3 dBA are considered barely perceptible, and changes of 5 dBA are considered readily perceptible.

The rumbling sound caused by the vibration of room surfaces is called structure-borne noise. Sources of ground-borne vibrations 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 (7). 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 (7). 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 different methods that are used to quantify vibration. The peak particle velocity (PPV) is defined as the maximum instantaneous peak of the vibration signal (7). The PPV is most frequently used to describe vibration impacts to buildings but is not always suitable for evaluating human response (annoyance) because it takes some time for the human body to respond to vibration signals. Instead, the human body responds to average vibration amplitude, often described as the root mean square (RMS). The RMS amplitude is defined as the average of the squared amplitude of the signal and is most frequently used to describe the effect of vibration on the human body (7). However, the RMS amplitude and PPV are related mathematically, and the RMS amplitude of equipment is typically calculated from the PPV reference level. The RMS amplitude is approximately 70% of the PPV (8). Thus, either can be used in the description of vibration impacts. While not universally accepted, vibration decibel notation (VdB) is another vibration notation developed and used by the FTA in their guidance manual to describe vibration levels, provide a background of common vibration levels, and set vibration limits (9). 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 50 VdB. Ground-borne vibration is normally perceptible to humans at approximately 65 VdB. For most people, a vibration-velocity level of 75 VdB is the approximate dividing line between 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 50 VdB, which is the typical background vibration-velocity Surf Farm Noise Analysis 16241-07_NA.docx 12 level, to 100 VdB, which is the general threshold where minor damage can occur in fragile buildings. Exhibit 2-C illustrates common vibration sources and the human and structural response to ground-borne vibration.

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 generally 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 per guidelines adopted by the Governor’s Office of Planning and Research (OPR). (10) 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 CODE The State of California’s noise insulation standards are codified in the California Code of Regulations, Title 24, Building Standards Administrative Code, Part 2, and the California Building Code. These noise standards are applied to new construction in California for the purpose of controlling interior noise levels resulting from exterior noise sources. The regulations specify that acoustical studies must be prepared when noise-sensitive structures, such as residential buildings, schools, or hospitals, are developed near major transportation noise sources, and where such noise sources create an exterior noise level of 60 dBA CNEL or higher. Acoustical studies that accompany building plans for noise-sensitive land uses must demonstrate that the structure has been designed to limit interior noise in habitable rooms to acceptable noise levels. For new residential buildings, schools, and hospitals, the acceptable interior noise limit for new construction is 45 dBA CNEL. The Project is required to comply with this standard by State law and the City verifies compliance during the plan check process as ministerial process. 3.3 CITY OF NEWPORT BEACH GENERAL PLAN NOISE ELEMENT The City of Newport Beach has adopted a Noise Element of the General Plan to control noise in the planning process in order to maintain compatible land use with environmental noise levels and to ensure that Newport Beach residents will be protected from excessive noise intrusion. (11) Surf Farm Noise Analysis 16241-07_NA.docx 14 3.3.1 NOISE POLICIES To protect City of Newport Beach residents from excessive noise, the Noise Element contains the following policies related to the Project. Noise and Land Use Compatibility N 1.1 Noise Compatibility of New Development: Require that all proposed projects are compatible with the noise environment through use of Table N2 and enforce the interior and exterior noise standards shown in Table N3. N 1.2 Noise Exposure Verification for New Development: Applicants for proposed residential or mixed-use projects located in areas projected to be exposed to 60 dBA CNEL and higher, as shown in Figures N1 through N6 must conduct a noise study to provide evidence that the depicted noise contours do not adequately account for local noise exposure circumstances due to such factors as, topography, variation in traffic speeds, and other applicable conditions. These findings shall be used to determine the level of exterior or interior noise, attenuation needed to attain an acceptable noise exposure level and the feasibility of such measures when other planning considerations are taken into account. (Imp 2.1) N 1.4 New Developments in Urban Areas: Require that applicants of residential portions of mixed-use projects and high density residential developments in urban areas (such as the Airport Area and Newport Center) demonstrate that the design of the structure will adequately isolate noise between adjacent uses and units (common floor/ceilings) in accordance with the California Building Code. (Imp 7.1) N 1.5 Infill Projects: Allow a higher exterior noise level standard for infill projects in existing residential areas adjacent to major arterials if it can be shown that there are no feasible mechanisms to meet the exterior noise levels. The interior standard of 45 dBA CNEL shall be enforced for any new residential project or mixed-use project containing a residential component. (Imp 2.1, 7.1) N1.5A Airport Area Infill Projects: Allow infill residential projects proximate to John Wayne Airport to have a higher exterior noise level standard if it can be shown that there are no practical mechanisms or designs to meet the exterior noise levels. The interior standard of 45 dBA CNEL shall be enforced for any residential component of projects. No residential units may be located in the 70 dBA CNEL or higher noise contour areas. N 1.8 Significant Noise Impacts: Require the employment of noise mitigation measures for existing sensitive uses when a significant noise impact is identified. A significant noise impact occurs when there is an increase in the ambient CNEL produced by new development impacting existing sensitive uses. The CNEL increase is shown in the table below.

N 2.2 Design of Sensitive Land Uses: Require the use of walls, berms, interior noise insulation, double paned windows, advanced insulation systems, or other noise measures, as appropriate, in the design of new residential developments to attenuate noise levels to not exceed 45 dBA CNEL interior or other new noise sensitive land uses that are adjacent to arterials and located proximate to John Wayne Airport. Residential uses within the 65 dBA to 70 dBA CNEL noise contour area are required to be indoor-oriented to reduce noise impacts on outdoor living or recreational areas. Application of the Noise Standards in Table N2 shall govern this requirement. Aircraft Noise N 3.1 New Development: Ensure new development is compatible with the noise environment proximate to John Wayne Airport by not allowing residential units in areas subjected to noise exceeding 70 dBA CNEL as shown in Figures N1, N2, N4, and N5 of the Noise Element of the General Plan.

Require developers of residential or mixed-use land uses with a residential component to notify prospective purchasers or tenants of aircraft noise. Additionally, require outdoor common areas or recreational areas of residential or mixed-used developments to be posted with signs notifying users regarding the proximity to John Wayne Airport and the presence of operating aircraft and noise. (Imp 2.1, 3.1, 4.1) Nontransportation-Related Noise N 4.1 Stationary Noise Sources: Enforce interior and exterior noise standards outlined in Table N3, and in the City’s Municipal Code to ensure that sensitive noise receptors are not exposed to excessive noise levels from stationary noise sources, such as heating, ventilation, and air conditioning equipment.

The compatibility criteria, shown on Exhibit 3-A, provides the City with a planning tool to gauge the compatibility of land uses relative to existing and future exterior noise levels and prevent noise/land use conflicts. The Land Use Noise Compatibility Matrix in the City of Newport Beach General Plan provides guidelines to evaluate the acceptability of transportation-related noise level impacts.

Surf Farm Noise Analysis 16241-07_NA.docx 17 3.4 CITY OF NEWPORT BEACH STATIONARY (NON-TRANSPORTATION) NOISE STANDARDS In addition to the noise/land use compatibility guidelines contained in the General Plan Noise Element, the City of Newport Beach has adopted Community Noise Control policies and standards as part of its Municipal Code to limit unnecessary, excessive and annoying noise in the City. To analyze noise impacts originating from a designated fixed location or private property such as the Project, stationary-source noise such as the expected roof-top air conditioning units, trash enclosure activity, loading activity, surf lagoon activity, satellite speakers, main announcement speakers, wave machine activity, water heating equipment, spectator activity, and parking lot vehicle movements and noise from construction activities are typically evaluated against standards established under the City’s Municipal Code. 3.4.1 OPERATIONAL NOISE STANDARDS The City of Newport Beach Municipal Code, Chapter 10.26 Community Noise Control, establishes the permissible exterior noise levels that may intrude into a neighboring property. According to Section 10.26.025(A) exterior noise levels at single-, two or multiple-family residential land uses (Noise Zone 1) shall not exceed 55 dBA Leq during the daytime hours (7:00 a.m. to 10:00 p.m.) and 50 dBA Leq during the nighttime hours (10:00 p.m. to 7:00 a.m.). (12) For commercial uses, exterior noise levels shall not exceed 65 dBA Leq during the daytime hours (7:00 a.m. to 10:00 p.m.) and 60 dBA Leq during the nighttime hours (10:00 p.m. to 7:00 a.m.). According to Section 10.26.025(C), in the event the ambient noise level exceeds the noise standard, the maximum allowable noise level under said category shall be increased to reflect the maximum ambient noise level. The City of Newport Beach Municipal Code, Chapter10.26 Community Noise Control exterior noise level standards are shown in Table 3-1 and are included in Appendix 3.1. TABLE 3-1: OPERATIONAL NOISE STANDARDS City Land Use Time Period Base Exterior Noise Level Standards (dBA Leq)2 Newport Beach1 Residential (Noise Zone I) Daytime 55 Nighttime 50 Commercial (Noise Zone II) Daytime 65 Nighttime 60 1 Source: City of Newport Beach Municipal Code, Section 10.26.025 (Appendix 3.1). 2 Base exterior noise level standards. If the ambient level exceeds allowable exterior Leq noise level, the ambient shall be the standard per Section 10.26.025 (C) of the City of Newport Beach Municipal Code. “Daytime” = 7:00 a.m. to 10:00 p.m.; “Nighttime” = 10:00 p.m. to 7:00 a.m. Surf Farm Noise Analysis 16241-07_NA.docx 18 3.5 VIBRATION 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. (7) To analyze vibration impacts originating from the operation and construction of the Project, vibration-generating activities are appropriately evaluated against standards established under the Municipal Code if such standards exist. However, the City of Newport Beach does not identify specific construction vibration level limits. Therefore, for analysis purposes, the Caltrans Transportation and Construction Vibration Guidance Manual (8), Table 19, vibration levels are used in this noise study to assess potential temporary construction- related impacts at adjacent building locations. This is considered the most appropriate standard and location for assessing vibration impacts, since vibration impacts are only assessed within structures, vibrations in outdoor environments are generally not an environmental concern, and temporary annoyance is not generally considered a substantial effect on the environment. The nearest vibration-sensitive buildings to the Project site can best be described as “older residential structures” with a maximum acceptable continuous vibration threshold of 0.3 PPV (in/sec). 3.6 AIRPORT LAND USE COMPATIBILITY John Wayne Airport (JWA) is located approximately 2,580 feet northeast of the Project site. The AELUP (13) prepared by the Orange County Airport Land Use Commission (ALUC), identifies noise compatibility policies to safeguard the general welfare of the inhabitants within the vicinity of the airport and to ensure the continued operation of the airport. Specifically, the AELUP plan seeks to protect the public from the adverse effects of aircraft noise, to ensure that people and facilities are not concentrated in areas susceptible to aircraft accidents, and to ensure that no structures or activities adversely affect navigable airspace. The basic function of the AELUP is to promote compatibility between the airport and the land uses that surround it. As required by State law, the AELUP provides guidance to affected local jurisdictions regarding airport land use compatibility. The main objective of the AELUP is to avoid future compatibility conflicts rather than to remedy existing incompatibilities. Also, the AELUP is aimed at addressing future land uses and development, not airport activity. The AELUP does not place any restrictions on the present and future role, configuration, or use of the airport. The AELUP establishes aircraft noise exposure exterior noise level compatibility thresholds for new developments by land use category. According to the exterior noise thresholds outlined in Exhibit 3-B, Commercial development is considered normally consistent with exterior noise levels of less than 70 dBA CNEL and conditionally consistent with exterior noise levels greater than 70 dBA CNEL. Noise level contours are available from three different sources: the first and most recent noise level contours are maintained on the airport’s website and updated annually, the next most current is from the City’s General Plan, and the oldest are included in the AELUP. As shown in Exhibit 3-C, based on the 2024 Annual CNEL Noise Level Contours issued by John Wayne Airport, the Project Site is located between the 70 dBA CNEL and 65 dBA CNEL aircraft noise level contours. (14) As shown in Exhibit 3-D, based on the City of Newport General Plan Noise Level Contours for John Wayne Airport, the Project Site is located between the 70 dBA CNEL and 60 dBA CNEL aircraft noise level contours and bisected by the 65 dBA CNEL noise level contour. (11) Finally, as shown in Exhibit 3-E, based Surf Farm Noise Analysis 16241-07_NA.docx 19 on the AELUP CNEL Noise Level Contours for the John Wayne Airport, the Project Site is located between the 75 dBA CNEL and 65 dBA CNEL noise level contours, with the 70 dBA CNEL contour clipping the northwestern tip of the on-site parking and equipment yard. (13) Thus, in all three sources, the main Project site is exposed to normally consistent noise levels from airport operations.

(1) 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? While the City of Newport Beach General Plan Guidelines provide direction on noise compatibility and establish noise standards by land use type that are sufficient to assess the significance of noise impacts; they do not define the levels at which increases are considered substantial for use under Guideline A. CEQA Appendix G Guideline C applies to nearest public and private airports, if any, and the Project’s land use compatibility. 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. (15) This is primarily because of the wide variation in individual thresholds of annoyance and differing individual experiences with noise. 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. 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. The ambient noise level is the composite of noise from all sources, excluding the alleged offensive noise. In this context, it represents the normal or existing level of environmental noise at a given location for a specified time of day or night. 4.1.1 TRANSPORTATION NOISE (SUBSTANTIAL PERMANENT NOISE LEVEL INCREASE) The Federal Interagency Committee on Noise (FICON) (16) 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). Surf Farm Noise Analysis 16241-07_NA.docx 24 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 2008 California Court of Appeal ruling on Gray v. County of Madera. (15) For example, if the ambient noise environment is quiet (<60 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 5 dBA or greater project-related noise level increase is considered a significant impact when the without project noise levels are below 60 dBA. Per the FICON, in areas where the without project noise levels range from 60 to 65 dBA, a 3 dBA barely perceptible noise level increase appears to be appropriate for most people. When the without project noise levels already exceed 65 dBA, any increase in community noise louder than 1.5 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 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 5 dBA or readily perceptible, 3 dBA or barely perceptible, and 1.5 dBA depending on the underlying without Project noise levels for noise-sensitive uses. These levels of increases and their perceived acceptance at noise sensitive receiver locations are consistent with guidance provided by both the Federal Highway Administration (17 p. 9) and Caltrans (18 p. 2_48). The City of Newport Beach General Plan Noise Element, Noise Compatibility by Land Use Type was used to establish the satisfactory noise levels of significance for non-noise-sensitive land uses in the Project study area. As previously shown on Exhibit 3-A, the completely compatible exterior noise level for non-noise-sensitive land uses is 70 dBA CNEL. To determine if Project-related traffic noise level increases are significant at off-site non-noise-sensitive land uses, a barely perceptible 3 dBA criteria is used. When the without Project noise levels are greater than the completely compatible 70 dBA CNEL land use compatibility criteria, a barely perceptible 3 dBA or greater noise level increase is considered a significant impact since the noise level criteria is already exceeded. The noise level increases used to determine significant impacts for non-noise- sensitive land uses is generally consistent with the FICON noise level increase thresholds for noise-sensitive land uses but instead rely on the City of Newport Beach General Plan Noise Element, Noise Compatibility by Land Use Type completely compatible 70 dBA CNEL exterior noise level criteria. 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 5 dBA or readily perceptible, 3 dBA or barely perceptible, and 1.5 dBA depending on the underlying ambient noise levels. Surf Farm Noise Analysis 16241-07_NA.docx 25 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. Therefore, the Caltrans Traffic Noise Analysis Protocol 12 dBA Leq substantial noise level increase threshold is used in this analysis to assess temporary noise level increases. (19) In California a substantial noise increase is considered to occur when the project’s predicted noise level exceeds the existing noise level by 12 dBA or more. The use of 12 dB was established in California many years ago and is based on the concept that a 10 dB increase generally is perceived as a doubling of loudness. (2 pp. 3-2) Therefore, if the Project-related construction noise levels generate a temporary noise level increase above the existing ambient noise levels of up to 12 dBA Leq, then the Project construction noise level increases will be considered a potentially significant impact. 4.2 VIBRATION (THRESHOLD B) As described in Section 3.5, the vibration impacts are appropriately evaluated using the Caltrans vibration damage thresholds to assess potential temporary construction-related impacts at adjacent building locations. The nearest vibration-sensitive buildings to the Project site can best be described as “older residential structures” with a maximum acceptable continuous vibration threshold of 0.3 PPV (in/sec). 4.3 CEQA GUIDELINES 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 Project site is not located within two miles of an airport or airstrip. The closest airport is the John Wayne Airport (JWA), located roughly 2,580 feet northeast of the Project site. The Project site is exposed to normally compatible noise levels for commercial office and retail land uses. As such, the Project site would not be exposed to excessive noise levels from airport operations, and 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. Surf Farm Noise Analysis 16241-07_NA.docx 26 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.

The measurement locations were selected to describe and document the existing noise environment within the Project study area. Exhibit 5-A provides the boundaries of the Project study area and the noise level measurement locations. To fully describe the existing noise conditions, noise level measurements were collected by Urban Crossroads, Inc. on Thursday, September 12th, 2024. Appendix 5.1 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 24-hour period. By collecting individual hourly noise level measurements, it is possible to describe the daytime and nighttime hourly noise levels and calculate the 24-hour CNEL. The long-term noise readings were recorded using Piccolo Type 2 integrating sound level meter and dataloggers. The Piccolo sound level meters were calibrated using a Larson-Davis calibrator, Model CAL 150. 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 S1.4-2014/IEC 61672-1:2013. (20) 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 ambient 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. (2) 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. (7) 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. (7) 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. Collecting reference ambient noise level measurements at the nearest sensitive receiver locations allows for a comparison of the before and after Project noise levels Surf Farm Noise Analysis 16241-07_NA.docx 28 and is necessary to assess potential noise impacts due to the Project’s contribution to the ambient noise levels. 5.3 NOISE MEASUREMENT RESULTS The noise measurements presented below focus on the average or equivalent sound levels (Leq). 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. Table 5-1 identifies the hourly daytime (7:00 a.m. to 10:00 p.m.) and nighttime (10:00 p.m. to 7:00 a.m.) noise levels at each noise level measurement location.

These daytime and nighttime energy average noise levels represent the average of all hourly noise levels observed during these time periods expressed as a single number. Appendix 5.2 provides summary worksheets of the noise levels for each hour as well as the minimum, maximum, L1, L2, L5, L8, L25, L50, L90, L95, and L99 percentile noise levels observed during the daytime and nighttime periods. Surf Farm Noise Analysis 16241-07_NA.docx 29 The background ambient noise levels in the Project study area are dominated by the overflight of airplanes from John Wayne Airport and transportation-related noise associated with surface streets, including the auto and heavy truck activities on study area roadway segments near the noise level measurement locations. The 24-hour existing noise level measurement results are shown in Table 5-1.

(21) 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 and no further analysis is required.

Surf Farm Noise Analysis 16241-07_NA.docx 33 7 RECEIVER LOCATIONS To assess the potential for long-term operational and short-term construction noise impacts, the following sensitive receiver locations, as shown in Exhibit 7-A, were identified as representative locations for analysis. 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, eight receiver locations in the vicinity of the Project site were identified. All distances are measured from the Project site boundary to the outdoor living areas (e.g., private backyards) or at the building façade, whichever is closer to the Project site. 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 5.2. Other sensitive land uses in the Project study area that are located at greater distances than those identified in this noise analysis 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. R1: Location R1 represents a noise-sensitive residence at 20352 Kline Drive, 399 feet northwest of the Project site. Receiver R1 is placed at the use area (backyard) facing the Project site. R2: Location R2 represents a noise-sensitive residence at 1691 Mesa Drive, 256 feet northwest of the Project site. Receiver R2 is placed at the use area (pool) facing the Project site. R3: Location R3 represents a noise-sensitive residence at 1691 Mesa Drive, 169 feet northwest of the Project site. Receiver R3 is placed at the building façade facing the Project site.

Exhibit 8-A identifies the representative noise source locations used to assess the operational noise levels. The on-site Project-related operational noise sources are expected to include: roof-top air conditioning units, trash enclosure activity, loading activity, surf lagoon activity, satellite speakers, main announcement speakers, wave machine activity, water heating equipment, spectator activity, and parking lot vehicle movements. 8.1 REFERENCE OPERATIONAL NOISE LEVELS To estimate the Project's operational noise impacts, reference noise level measurements were collected from similar sources and types of activities to represent the noise levels expected with the development of the Project. This section provides a description of the reference noise levels shown in Table 8-1 used to estimate the Project's operational noise impacts. It is important to note that the following projected noise levels assume the worst-case noise environment with the roof-top air conditioning units, trash enclosure activity, loading activity, surf lagoon activity, satellite speakers, main announcement speakers, wave machine activity, water heating equipment, spectator activity, and parking lot vehicle movements. Appendix 8.1 includes the detailed calculations for the Project operational noise levels presented in this section. 8.1.1 MEASUREMENT PROCEDURES The reference noise level measurements presented in this section were collected using a combination of Type 1 and Type 2 sound level meters. Each sound level meter was programmed in “slow” mode to record noise levels in “A” weighted form and calibrated prior to each measurement. 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 S1.4- 2014/IEC 61672-1:2013. (20) 8.1.2 ROOF-TOP AIR CONDITIONING UNIT To assess the noise levels created by the roof-top air conditioning unit, reference noise levels were taken from a 3- to 12.5-ton Carrier Weathermaster Commercial Packaged Rooftop Unit model 48HC product datasheet. The product data sheet for Carrier model 48HC indicates that each air conditioning unit will produce a maximum sound power level of 57.4 dBA Leq at 50 feet, based on a sound power rating of 89 dBA Lw. Each air conditioning unit was modeled as operating at full power for 45 minutes per hour during the daytime and 30 minutes during the nighttime. The manufacturer’s specifications for the sample air conditioners are provided in Appendix 8.1.

The Project includes approximately 351 spaces, which are assumed to have and average of 2 movements per hour for a total of 702 events in an hour. Based on studies conducted in Europe and Australia, the average parking procedure, which included movement associated with either entering or exiting the parking area, parking the vehicles, and opening and closing doors, resulted in a sound power level of approximately 63 dBA Lw/square meter per event (22) (23). Parking lot activities were modeled at full activity during the daytime and nighttime hours. 8.1.4 TRASH ENCLOSURE ACTIVITY To describe the noise levels associated with trash enclosure activity, Urban Crossroads collected a reference noise level measurement at an existing trash enclosure containing two dumpster bins. The trash enclosure noise levels describe metal gates opening and closing, metal scraping against concrete floor sounds, dumpster movement on metal wheels, and trash dropping into the metal dumpster. The reference noise levels describe trash enclosure noise activities when trash is dropped into an empty metal dumpster, as would occur at the Project site. The measured reference noise level at the uniform 50-foot reference distance is 57.4 dBA Leq for the trash enclosure activity. The reference noise level describes the expected noise source activities associated with the trash enclosures for the Project’s proposed building. Typical trash enclosure activities are estimated to occur for 5 minutes per hour and may occur during either daytime or I Surf Farm Noise Analysis 16241-07_NA.docx 38 nighttime hours. Therefore, rash collection activities are conservatively included in both daytime and nighttime noise level estimates. 8.1.5 LOADING ACTIVITY The truck movements reference noise level measurement was collected over a period of 1 hour and 28 minutes and represents multiple heavy trucks entering and exiting the outdoor loading dock area producing a reference noise level of 69.8 dBA Leq at 50 feet. The noise sources included at this measurement location account for trucks entering and existing the Project driveways and maneuvering in and out of the outdoor loading dock activity area. 8.1.6 SATELLITE SPEAKERS The Project would include satellite speakers located near the seating and surf lagoon areas. To describe the worst-case reference noise level conditions, a reference noise level of 66.4 Leq at a distance of 50 feet is used. This is considered conservative since the Project’s goals are to create audible announcements within the seating areas and the average human raised voice is approximately 55 dBA at 10 feet, or approximately 41 dBA at 50 feet, thus the speaker is modeled at being approximately 4 times louder than the typical raised human voice. The will be limited to the hours of 7:00 a.m. to 10:00 p.m. 8.1.7 MAIN ANNOUNCEMENT SPEAKERS The Project would include several larger speakers located throughout the facility as shown in Exhibit 8-A, to provide announcements as well as music during outdoor events. To describe the worst-case reference noise level conditions, a reference noise level of 71.4 Leq at a distance of 50 feet is used. This is considered conservative since the Project’s goals are to create audible announcements, and the average human raised voice is 62.5 dBA at 10 feet or 48.6 dBA at 50 feet. Thus, the speaker is modeled as being approximately 4 times louder than the typical shouting human voice. The will be limited to the hours of 7:00 a.m. to 10:00 p.m. 8.1.8 WAVE MACHINE ACTIVITY To assess the noise levels created by the wave generator, reference noise levels were taken from a reference sheet for, The Wave, Bristol. To describe the worst-case reference noise level conditions, the highest reference noise level describing each peak wave noise event of 61.4 Leq at a distance of 50 feet is used. The wave basin/wave machine activities will be limited to the hours of 6:00 a.m. to 11:00 p.m. The manufacturer’s specifications for the wave generator are provided in Appendix 8.2. 8.1.9 WATER HEATING EQUIPMENT To determine the noise levels associated with water heating equipment, data was collected from AquaCal, which provides noise levels for its quietest unit against several other brands, based on the loudest reference noise level of 64.0 dBA at 10 feet. The measured reference noise level at 50 feet is 50.0 dBA Leq. The water heating equipment noise levels will be limited to the daytime hours of 7:00 a.m. to 10:00 p.m. with no planned nighttime activities. Surf Farm Noise Analysis 16241-07_NA.docx 39 8.1.10 SURF LAGOON, WARMING POOLS, AND SPA ACTIVITY To determine the noise levels associated with outdoor surf lagoon, warming pools, and spa activity, Urban Crossroads collected a reference noise level measurement at a swimming pool at a hotel. The measured reference noise level at 50 feet is 57.8 dBA Leq. The outdoor pool/spa activity noise levels include a waterfall, people talking, and children and adults swimming and playing in a pool. The outdoor pool/spa activities will be limited to the daytime hours of 7:00 a.m. to 10:00 p.m. with no planned nighttime activities. 8.1.11 SPECTATOR ACTIVITY To represent the potential noise level impacts associated with the Project’s outdoor or beach club activities, a reference noise level measurement was collected at an existing park and is expected to overestimate the noise level activities within the beach and club areas at the Project site, since the reference noise level measurement includes parents speaking on cell phones, kids playing, and background youth soccer games, with coaches shouting instructions and people cheering and clapping. Using the uniform reference distance of 50 feet, the reference noise level is 43.4 dBA Leq. The spectator activities will be limited to the hours of 6:00 a.m. to 11:00 p.m. 8.2 CADNAA NOISE 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 Development Site plan, georeferenced Nearmap aerial imagery, topography, buildings, and barriers in its calculations to predict outdoor noise levels. Using the ISO 9613 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 9613 protocol, the CadnaA noise prediction model relies on the reference sound power level (PWL) 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 (PWL) are connected to the sound source and are independent of distance. Sound pressure levels vary substantially with distance from the source and diminish from 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 analysis 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 0.5 was used in the CadnaA noise analysis to account for a mix of hard and soft site conditions. Appendix 8.3 includes the detailed noise model inputs. Surf Farm Noise Analysis 16241-07_NA.docx 40 8.3 PROJECT OPERATIONAL NOISE LEVELS Using the reference noise levels to represent the Project operations that include roof-top air conditioning units, trash enclosure activity, loading activity, surf lagoon activity, satellite speakers, main announcement speakers, wave machine activity, water heating equipment, spectator activity, and parking lot vehicle movements, 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 8-2 shows the Project operational noise levels during the daytime hours of 7:00 a.m. to 10:00 p.m. The daytime hourly noise levels at the off-site receiver locations are expected to range from 53.9 to 64.4 dBA Leq. Table 8-3 shows the Project operational noise levels during the nighttime hours of 10:00 p.m. to 7:00 a.m. The nighttime hourly noise levels at the off-site receiver locations are expected to range from 40.0 to 45.7 dBA Leq. The differences between the daytime and nighttime noise levels is largely related to the duration of noise activity (Table 8-1).

CadnaA noise model calculations are included in Appendix 8.3. 8.4 PROJECT OPERATIONAL NOISE LEVEL COMPLIANCE To demonstrate compliance with local noise regulations, the Project-only operational noise levels are evaluated against the City of Newport Beach exterior noise level standards at the nearest noise-sensitive receiver locations. For noise-sensitive residential land uses, the City of Newport Beach has established exterior noise level standards of 55 dBA Leq during the daytime hours (7:00 a.m. to 10:00 p.m.) and 50 dBA Leq during the nighttime hours (10:00 p.m. to 7:00 a.m.). (12) In the event the ambient noise level exceeds the noise standard, the maximum allowable noise level under said category shall be increased to reflect the maximum ambient noise level (Section 10.26.025(C)). Noise level limits in Table 8-4 have been adjusted based on the 24-hour noise level measurements in Table 5-1. Table 8-4 shows that the operational noise levels associated with the Project will satisfy the City of Newport Beach exterior noise level standards at all nearest receiver locations. Therefore, the operational noise impacts are considered less than significant at the nearest noise-sensitive receiver locations.

If the ambient level exceeds allowable exterior Leq noise level, the ambient shall be the standard per Section 10.26.025 (C) of the City of Newport Beach Municipal Code. 4 Do the estimated Project operational noise source activities exceed the noise level standards? “Daytime” = 7:00 a.m. to 10:00 p.m.; “Nighttime” = 10:00 p.m. to 7:00 a.m. 8.6 PROJECT OPERATIONAL NOISE LEVEL INCREASE To describe the Project operational noise level increase, the Project operational noise levels are combined with the existing ambient noise levels measurements for nearest receiver locations 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. (2) Instead, they must be logarithmically added using the following base equation: SPLTotal = 10log10[10SPL1/10 + 10SPL2/10 + … 10SPLn/10] Where “SPL1,” “SPL2,” 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 describe the Project noise level increase to the existing ambient noise environment. Noise levels that would be experienced at receiver locations when Project- source noise is added to the daytime ambient conditions are presented in Tables 8-5 and Table 8-6. As indicated in Table 8-5 and Table 8-6, the Project will generate daytime operational noise level increases ranging from less than 0.1 to 0.8 dBA Leq and nighttime noise level increases ranging from 0.1 to 2.0 dBA Leq at the nearby receiver locations. Project-related operational noise level increases will satisfy the operational noise level increase significance criteria presented in Table 4-1. Therefore, the incremental Project operational noise level increase is considered less than significant at all receiver locations.

Exhibit 9-A shows the construction activity boundaries in relation to the nearest sensitive receiver locations. 9.1 CONSTRUCTION NOISE SOURCES 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:  Demolition  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. (24) 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. (25) (7) (26) Consistent with FHWA and FTA guidance for detailed construction noise assessment, Table 9-1 presents the combined noise levels for the loudest construction activities expected for each stage, assuming all equipment operates simultaneously.

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. (7) (27) 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 9-2, the construction noise levels are expected to range from 50.0 to Surf Farm Noise Analysis 16241-07_NA.docx 48 63.8 dBA Leq at the nearby receiver locations.

CadnaA construction noise model inputs are included in Appendix 9.1. 9.4 CONSTRUCTION NOISE LEVEL COMPLIANCE The applicant has stated that they will abide by restrictions set by The City of Newport Beach to control noise impacts associated with the construction of the Project. According to the City of Newport Beach Municipal Code Section 10.28.040 (included in Appendix 3.2): A. No person shall, while engaged in construction, remodeling, digging, grading, demolition, painting, plastering or any other related building activity, operate any tool, equipment or machine in a manner which produces loud noise that disturbs, or could disturb, a person of normal sensitivity who works or resides in the vicinity, unless authorized to do so in accordance with subsection (B) of this section. B. The provisions of subsection (A) of this section shall not apply to the following: 1. Work performed on any weekday, which is not a federal holiday, between the hours of 7:00 a.m. and 6:30 p.m. 2. Work performed on a Saturday, in any area of the City that is not designated as a high- density area, between the hours of 8:00 a.m. and 6:00 p.m. 3. Emergency work performed pursuant to written authorization of the Community Development Director, or his or her designee. 4. Maintenance, repair or improvement of any public work or facility by public employees, by any person or persons acting pursuant to a public works contract, or by any person or persons performing such work or pursuant to the direction of, or on behalf of, any public agency; provided, however, this exception shall not apply to the City of Newport Beach, or its employees, contractors or agents, unless: Surf Farm Noise Analysis 16241-07_NA.docx 49 Construction activities are considered exempt from the noise standards of the noise ordinance and are limited to the hours of 7:00 a.m. to 6:30 p.m. on Mondays to Fridays and 8:00 a.m. to 6:00 p.m. on Saturdays, with no activity allowed on Sundays or national holidays. (28) For informational purposes, the Project’s construction noise levels are compared against the FTA’s acceptable construction noise level of 80 dBA Leq for sensitive receiver locations. Table 9-3 shows the highest construction noise levels at the potentially impacted receiver locations, which are estimated to range from 57.6 to 63.8 dBA Leq. The noise impact due to Project construction noise levels is considered a less than significant impact at all nearest sensitive receiver locations. TABLE 9-3: CONSTRUCTION EQUIPMENT NOISE LEVEL COMPLIANCE Receiver Location1 Land Use2 Highest Construction Noise Levels (dBA Leq)3 R1 80 62.0 R2 80 62.5 R3 80 63.8 R4 80 58.7 R5 80 61.3 R6 80 57.7 R7 80 57.6 R8 80 60.3 1 Noise receiver locations are shown on Exhibit 7-A. 2 City of Newport Beach Interactive Map (Zoning) 3 Estimated construction noise levels during peak operating conditions, as shown in Table 9-2. These less than significant findings are consistent with the 2006 General Plan Environmental Impact Report (EIR) (29): Construction activities would be an ongoing occurrence in the City and, in particular cases, could occur in close proximity to noise-sensitive uses. Although the proposed General Plan Update limits construction activities to specific days of the week and hours of the day, construction equipment generates high noise levels, as shown in Table 4.9-9, and may not always be reducible to the levels specified in the City Noise Ordinance. Section 10.26.035 of the Municipal Code (Exemptions), exempts “noise sources associated with construction, repair, remodeling, demolition, or grading of any real property.” Section 10.26.035 also states that construction noise should fall under the provisions of Section 10.28 of the Code (Loud and Unreasonable Noise). Thus, construction noise is not subject to the noise standards in the Municipal Code, but only during limited hours of the day and days of the week. In sum, existing and future construction noise levels at individual construction sites may not substantially differ, but previously unexposed areas could experience new sources of construction noise. Both existing and future noise would be exempt from the City code and when construction noise occurs, impacts would be considered less than significant. Surf Farm Noise Analysis 16241-07_NA.docx 50 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 locations when Project construction-source noise is added to the ambient daytime conditions are presented in Table 9-4. A temporary noise level increase of 12 dBA is considered a potentially significant impact based on the typical difference in operational property line limits and construction noise level limits.

As indicated in Table 9-4, the Project construction will contribute to noise level increases ranging from 0.2 to 1.1 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 substantial 12 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 Project construction noise are considered less than significant. 9.5 CONSTRUCTION VIBRATION IMPACTS Construction activity can result in varying degrees of ground vibration, depending on the equipment and methods employed. Operation of construction equipment causes ground vibrations that spread through the ground and diminish in strength with distance. Ground Surf Farm Noise Analysis 16241-07_NA.docx 51 vibration levels associated with various types of construction equipment are summarized on Table 9-4. Based on the representative vibration levels presented for various construction equipment types, it is possible to estimate the potential vibration ranges using the following vibration assessment methods defined by Caltrans. To describe the vibration impacts Caltrans provides the following equation: PPVequip = PPVref x (25/D)1.1 TABLE 9-4: VIBRATION SOURCE LEVELS FOR CONSTRUCTION EQUIPMENT Equipment PPV (in/sec) at 25 feet Small bulldozer 0.003 Jackhammer 0.035 Loaded Trucks 0.076 Large bulldozer 0.089 Caltrans Transportation and Construction Vibration Guidance Manual, 2020. Using the vibration source level of construction equipment provided in Table 9-4 and the construction vibration assessment methodology published by Caltrans, it is possible to estimate the Project vibration impacts. Table 9-5 presents the expected Project-related vibration levels at the nearby receiver locations. At distances ranging from 169 to 797 feet from Project construction activities, construction vibration velocity levels are estimated to range from 0.00 to 0.01 PPV in/sec. Based on the maximum acceptable continuous vibration threshold of 0.30 PPV in/sec, the typical Project construction vibration levels will fall below the building damage thresholds at all the vibration-sensitive receiver locations. Therefore, the Project-related vibration impacts are considered less than significant during construction activities at the Project site.

INTRODUCTION Hydrock have been appointed by Wavegarden to provide a detailed analysis of noise specifically waves generation at The Wave, Bristol in relation to noise modelling of potential future domestic and international schemes where wave noise itself may be a concern for operators and patrons. For example, urban installations near existing sensitive receptors or new accommodation, or those installations featuring an enclosing roof structure which will result in potential noise build up within the facility itself impacting patrons. Short term noise measurements were undertaken at a range of locations to capture expected sound pressure levels immediately near the pool surface during various modes of operation. Additional long term noise monitoring was undertaken at the site boundary in two locations to inform noise modelling and extrapolation of distance attenuation of wave generated noise because of the development at the site boundaries. ϭϬϱ Hydrock 1: I I TECHNICAL DESIGN NOTE TECHNICAL DESIGN NOTE | Wave, Bristol | 23919-HYD-ZZ-XX-TN-1001-P01 | 29 September 2022 2 2. SITE SURVEY SUMMARY 2.1 Overview The survey measurement locations, operational modes captured, measurement summary and commentary are provided below. 2.1.1 Equipment Noise measurements were made at a free-field location using Class 1, integrating sound level meters. Microphones were positioned on a tripod with extendable horizontal boom arm at least 2m out over the lake surface for measurements, 2m above the surf lake surface for positions STM4-9. Positions STM1-3 were measured on a vertical boom at 2m height above the beach area. The sound level meters were calibrated to a reference level of 94 dB at 1kHz both prior to, and on completion of, the noise survey. No significant drift in calibration was noted during the survey (≤ 0.5 dB). All measurement equipment has been laboratory calibrated within the appropriate calibration interval. Details of the equipment used for the environmental noise measurements are shown in Table 1.

EXTRAPOLATED NOISE MODELLING EXERCISE Based on the noise survey undertaken noise models have been produced for The Wave, Bristol, observations are such that as anticipated, in areas closer to the wave generation areas, there is an increase in noise levels with levels up to 79dB LAeq, T at 2m. Other areas indicated lower noise levels form 68-75dBA above the lake surface. The measurements undertaken have been reviewed to produce a predicted sound power level area source for the pool in a segmented approach, spread across the surface area of the pool. Which was then aligned to the measurements undertaken immediately above the lake surface. This was further calibrated against both the measured sound pressure levels near the lake surface, as well as the distanced remote long term noise loggers at the site boundary for the cumulative result. Based on the measurements undertaken there is little difference in average noise levels circa 1-2dB between Expert B2 and B6, on this basis the noise models for B6 have been presented as worst case. Figures 3 and 4 below, show a plan view of the predicted sound pressure levels in the horizontal plane because of the Wave, Bristol, as well as a sectional view of the predicted sound pressure levels emanating in the vertical axis. 112 Hydrock 1: TECHNICAL DESIGN NOTE TECHNICAL DESIGN NOTE | Wave, Bristol | 23919-HYD-ZZ-XX-TN-1001-P01 | 29 September 2022 9 Figure 3: Expert B6-Plan View Noise Map 113 g ;;:; <D ~ 0 M <D g g <D 0 1/) 0) N <D g 0) N <D ~ 0 1/) <D ~ 357900 357900 357950 357950 358000 358050 358100 358000 358050 358100 358150 358200 358250 358300 358150 358200 358250 358300 358350 358350 358400 0 0 ;;:; <D ~ 0 M <D g g <D 0 1/) 0) ~ g 0) N ..... -------'° -••• <40 40 <= ... < 4 5 -4 5 <= ... <50 -50 <= ... <55 -55 <= ... <60 -60 <= ... <65 -65 <= ... <70 -70 <= ... <75 -75 <= ... <80 -80 <= .. .

CONCLUSION A noise survey was undertaken to define in greater detail noise generated because of wave noise itself at The Wave Bristol. A combination of short-term measurements over the surf lake, as well as boundary measurements at the site for the purposes of model calibration were undertaken. A noise model has then been produced which could later be developed or modified to estimate the expected wave noise generation at other Wavegarden sites domestically and internationally. The full data set, and noise model files are available upon request. 115 Hydrock 1: Surf Farm Noise Analysis 16241-04_NA.docx This page was intentionally left blank. 116 Surf Farm Noise Analysis 16241-04_NA.docx APPENDIX 8.3: OPERATIONAL NOISE LEVEL CALCULATIONS 117 Surf Farm Noise Analysis 16241-04_NA.docx This page was intentionally left blank. 118 16241 - Surf Farm CadnaA Noise Prediction Model: 16241-04_Operation.cna Date: 15.04.25 Analyst: B.
