Introduction and Summary 1.1 PROJECT LOCATION AND SETTING The Honda Center is located at 2695 East Katella Avenue in the City of Anaheim, east of the State Route 57 (SR-57) and west of the Santa Ana River. It is bound on the north by Cerritos Avenue and to the south by Katella Avenue. The Honda Center is within a half mile northeast of the Stadium of Anaheim and the Anaheim Metrolink Station. Operational Characteristics The 650,000-square-foot Honda Center opened on June 19, 1993, after two years of construction. It can accommodate a maximum of 18,900 spectators depending on seating configuration, and the parking lots surrounding the Honda Center have 4,500 parking spaces to accommodate visitors. The Honda Center facilities are in operation on event days, although some functions ticket sales) are open on non-event days. Maximum capacities for hockey, basketball, and other events concerts, circus, etc.) are shown in Table 1.

During the Stanley Cup Playoffs and Stanley Cup, up to 20 additional games could occur. ---PAGE BREAK--- 1. Introduction and Summary Page 2 The Planning CenterIDC&E January 2012 In 2010, the Honda Center welcomed more than 1.3 million guests, of which over 600,000 attended the Ducks’ hockey games (Starkey 2011). Table 2 identifies a five-year snapshot of attendance, number of events, and the average number of visitors during an event based on the annual attendance. Average attendance per event was calculated based on the highest 3-year average of attendance in order to provide a conservative estimate of future annual attendance. Based on the attendance history of the Honda Center over the last five years, there are, on average, 11,264 visitors per event and currently up to 153 events per year approximately three events per week).

The 1990 Environmental Impact Report (EIR) for the Honda Center (formerly the Arrowhead Pond) capped the number of annual events at 162 per year. The Honda Center averages up to 153 events per year with average attendance at an event of 11,264 people. The proposed project seeks to increase the maximum number of events by 60 from the permitted 162 events for a total of 222 events per year. Currently, there are on average, three events per week at the Honda Center and the proposed project would result in four events per week on average. The purpose of the project would be to accommodate a new permanent tenent at the Honda Center. Implementation of the proposed project would not increase the capacity of the arena. Seating capacity of a sellout event is 18,336 and the proposed project would not result in a change in the maximum seating capacity of current events (see Table Because project-generated vehicle trips would be similar to the current events held at the Honda Center area, noise increases in the ambient environment attributable to project-related trips would be comparable to the existing events currently permitted. Similarly, the proposed project would not generate stationary sources mechanical systems, parking lots, etc.) of noise that would different from the events currently permitted at the arena. Therefore, no noise impacts would occur from implementation of the project. ---PAGE BREAK--- 2. Environmental Setting 2.1 NOISE SETTING Noise is most often defined as unwanted sound. Although sound can be easily measured, the perception of noise and the physical response to sound complicate the analysis of its impact on people. People judge the relative magnitude of sound sensation in subjective terms such as “noisiness” or “loudness.” 2.1.1 Terminology and Noise Descriptors The following are brief definitions of terminology used in this chapter: Noise. Sound that is loud, unpleasant, unexpected, or otherwise undesirable. Decibel (dB). A unitless measure of sound on a logarithmic scale. A-Weighted Decibel (dBA). An overall frequency-weighted sound level in decibels that approximates the frequency response of the human ear. Equivalent Continuous Noise Level (Leq). The mean of the noise level averaged over the measurement period, regarded as an average level. Day-Night Level (Ldn). The energy average of the A-weighted sound levels occurring during a 24-hour period, with 10 dB added to the sound levels occurring during the period from 10:00 PM to 7:00 AM. Community Noise Equivalent Level (CNEL). The energy average of the A-weighted sound levels occurring during a 24-hour period with 5 dB added to the sound levels occurring during the period from 7:00 PM to 10:00 PM and 10 dB added to the sound levels occurring during the period from 10:00 PM to 7:00 AM. Ldn and CNEL values rarely differ by more than 1 dB. As a matter of practice, Ldn and CNEL values are considered to be equivalent and are treated as such in this assessment. 2.1.2 Characteristics of Sound When an object vibrates, it radiates part of its energy as acoustical pressure in the form of a sound wave. Sound can be described in terms of amplitude (loudness), frequency (pitch), or duration (time). Human hearing is not equally sensitive to sound at all frequencies. Therefore, to approximate a human response, the A-weighted filter system is used to adjust measured sound levels. In terms of loudness, the normal range of human hearing extends from approximately 0 dBA to 140 dBA. Unlike linear units such as inches or pounds, decibels are measured on a logarithmic scale, representing points on a sharply rising curve. Because of the physical characteristics of noise transmission and noise perception, the relative loudness of sound does not closely match the actual amounts of sound energy. Table 3, Change in Sound Pressure Level, presents the subjective effect of changes in sound pressure levels. The Honda Center Noise Technical Study City of Anaheim Page 3 ---PAGE BREAK--- 2. Environmental Setting Page 4 The Planning CenterIDC&E January 2012 Table 3 Change in Sound Pressure Level Change in Apparent Loudness ± 3 dB Threshold of human perceptibility ± 5 dB Clearly noticeable change in noise level ± 10 dB Half or twice as loud ± 20 dB Much quieter or louder Source: Bies and Hansen 2003. Sound is generated from a source and dissipates exponentially with distance from that source. This phenomenon is known as “spreading loss.” When sound is measured for distinct time intervals, the statistical distribution of the overall sound level during that period can be obtained. The energy-equivalent sound level (Leq) is the most common parameter associated with such measurements. The Leq metric is a single-number noise descriptor that represents the average sound level over a given period of time. For example, the L50 noise level represents the level that is exceeded 50 percent of the time. Half the time the noise exceeds this level and half the time it is less than this level. This level also represents the level that is exceeded 30 minutes in an hour. Similarly, the L02, L08 and L25 values represent the noise levels that are exceeded 2, 8, and 25 percent of the time or 1, 5, and 15 minutes per hour. Other values typically noted during a noise survey are the Lmin and Lmax. These values represent the minimum and maximum root-mean-square noise levels obtained over the measurement period. Because community receptors are more sensitive to unwanted noise intrusion during the evening and at night, state law requires that, for planning purposes, an artificial dB increment be added to quiet-time noise levels in a 24-hour noise descriptor, the CNEL or Ldn. 2.1.3 and Physiological Effects of Noise Physical damage to human hearing begins at prolonged exposure to noise levels higher than 85 dBA. Exposure to high noise levels affects the entire biological system, with prolonged noise exposure in excess of 75 dBA increasing body tensions, thereby affecting blood pressure and functions of the heart and nervous system. Extended periods of noise exposure above 90 dBA result in permanent cell damage. When the noise level reaches 120 dBA, a tickling sensation occurs in the human ear even with short-term exposure. This level of noise is called the threshold of feeling. As the sound reaches 140 dBA, the tickling sensation is replaced by the feeling of pain in the ear, called the threshold of pain. A sound level of 160 to 165 dBA will result in dizziness or loss of equilibrium. The ambient or background noise problem is widespread and generally more concentrated in urban areas than in outlying, less developed areas.

It is bordered by Katella Avenue to the south and Cerritos Avenue to the north. To the west ---PAGE BREAK--- 2. Environmental Setting Page 6 The Planning CenterIDC&E January 2012 is SR-57 and the Santa Ana River to the east. Douglass Road traverses through the site in a north/south orientation and separates the western surface lot from the arena and eastern surface parking lot. 2.2.1 Noise-Sensitive Receptors Certain land uses are particularly sensitive to noise and vibration, including residential, school, and open space/recreation areas where quiet environments are necessary for enjoyment, public health, and safety. The project site is primarily surrounded by commercial and light industrial land uses. Commercial and industrial uses are not considered noise sensitive. The Angel Stadium of Anaheim is located to the southwest. Information regarding sensitive receptors near the project site is provided below. Westwood College. Generally located northwest of the project site across Douglass Road. Ayres Hotel of Anaheim. Located south of the project site across Katella Avenue. Sunkist Gardens Mobile Home Park. Located approximately 1,675 feet to the northwest of the project site. 2.2.2 Existing Noise Environment Noise from motor vehicles is generated by engine vibrations, the interaction between tires and the road, and the exhaust system. Reducing the average motor vehicle speed reduces the noise exposure of receptors adjacent to the road. Each reduction of five miles per hour reduces noise by about 1 dBA. In order to assess the potential for mobile-source noise impacts, it is necessary to determine the noise currently generated by vehicles traveling through the project area. Average daily traffic (ADT) volumes were based on the existing daily traffic volumes provided by Parsons Brinkerhoff (2012). Noise levels for existing conditions (without and with event) along analyzed roadways are presented in Table 5. The results of this modeling indicate that current average noise levels along arterial segments for a typical day without an event range from approximately 63 to 77 dBA CNEL at 50-feet from the roadway centerline. Average noise levels along the arterial segments range from 66 to 78 dBA CNEL at 50- feet from the roadway centerline on a day with an event (based on an average attendance event). ---PAGE BREAK--- 2.

Regulatory Setting To limit population exposure to physically and/or 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. The City of Anaheim regulates noise through the City of Anaheim Municipal Code and General Plan. Potential noise impacts were evaluated based on the City of Anaheim Municipal Code and General Plan to determine whether a significant adverse noise impact would result from the operation of the proposed project. 3.1 STATE OF CALIFORNIA BUILDING CODE The state of California’s noise insulation standards are codified in the California Code of Regulations, Title 24, Part 2, California Building Code. These noise standards are applied to new construction in California for the purpose of interior noise compatibility 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 located 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 must demonstrate that the structure has been designed to limit interior noise in habitable rooms to acceptable noise levels. 3.2 CITY OF ANAHEIM NOISE STANDARDS 3.2.1 Land Use Compatibility Table 6 presents a land use compatibility chart for community noise adopted by the City of Anaheim’s General Plan Noise Element. This table provides urban planners with a tool to gauge the compatibility of new land uses relative to existing and future noise levels. This table identifies normally acceptable, conditionally acceptable, normally unacceptable, and clearly unacceptable noise levels for various land uses. A conditionally acceptable designation implies new construction or development should be undertaken only after a detailed analysis of the noise reduction requirements for each land use is made and needed noise insulation features are incorporated in the design. By comparison, a normally acceptable designation indicates that standard construction can occur with no special noise reduction requirements.

Normally Unacceptable: New construction/development should generally be discouraged. If new construction or development does proceed, a detailed analysis of the noise reduction requirements must be made with needed noise insulation features included in the design. Outdoor areas must be shielded. Clearly Unacceptable: New construction/development should generally not be undertaken. Construction costs to make the indoor environment acceptable would be prohibitive and the outdoor environment would not be useable. Conditionally Acceptable: New construction/development should be undertaken only after a detailed analysis of the noise reduction requirement is made and needed noise insulation features included in the design. Conventional construction, but with closed windows and fresh air supply systems or air conditioning will normally suffice. Outdoor environment will seem noisy.

Regulatory Setting The Honda Center Noise Technical Study City of Anaheim Page 11 3.2.2 Municipal Code The City of Anaheim regulates noise through the City of Anaheim’s Municipal Code, Chapter 6.70, Sound Pressure Levels. Pursuant to the municipal code, the City restricts noise levels generated at a property from exceeding 60 dBA for extended period of time. The City applies these standards to nontransportation stationary noise sources. These standards do not gauge the compatibility of developments in the noise environment, but provide restrictions on the amount and duration of noise generated at a property, as measured at the property line of the noise receptor. The City’s noise ordinance is designed to protect people from objectionable nontransportation noise sources such as music, construction activity, machinery, pumps, and air conditioners. ---PAGE BREAK--- 3.

Environmental Impacts 4.1 METHODOLOGY This noise technical study has been prepared to analyze potential operational phase noise impacts related to an increase in the number of annual events at the Honda Center to accommodate a NBA franchise. The Honda Center is permitted to host up to 162 events per year. The proposed project seeks to increase the maximum number of events by 60 for a total of 222 events per year. Currently, there are on average three events per week at the Honda Center (153 games per year) and the proposed project would result in four events per week on average. Seating capacity of a basketball game is 18,336 and the proposed project would not result in a change in the maximum seating capacity of current events (see Table No construction activities would be necessary in order to accommodate an increase of events at the Honda Center. 4.2 THRESHOLDS OF SIGNIFICANCE According to Appendix G of the CEQA Guidelines, a project would normally have a significant effect on the environment if the project would result in: N-1 Exposure of persons to or generation of noise levels in excess of standards established in the local general plan or noise ordinance, or applicable standards of other agencies. N-2 Exposure of persons to or generation of excessive groundborne vibration or groundborne noise levels. N-3 A substantial permanent increase in ambient noise levels in the project vicinity above levels existing without the project. N-4 A substantial temporary or periodic increase in ambient noise levels in the project vicinity above levels existing without the project. N-5 For a project located within 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, expose people residing or working in the project area to excessive noise levels. N-6 For a project within the vicinity of a private airstrip, expose people residing or working in the project area to excessive noise levels. 4.2.1 City of Anaheim Thresholds Noise There are two criteria for judging noise impacts used in this analysis. First, noise levels projected for the proposed project must comply with all relevant state and local standards and regulations. Noise impacts on the surrounding community are enforced through local noise ordinances, supported by nuisance complaints and subsequent investigation. The second measure of impact used in this analysis is whether the increase in noise above the ambient noise level, as a result of a new noise source (either through on-site emissions or through noise generated by project traffic), has the potential to adversely impact noise-sensitive land uses. The Honda Center Noise Technical Study City of Anaheim Page 13 ---PAGE BREAK--- 4. Environmental Impacts Page 14 The Planning CenterIDC&E January 2012 Substantial Increase in Traffic Noise Levels The traffic noise thresholds are based on human tolerance to noise (see Table 3, shown previously) and are widely used for assessing traffic noise impacts. In general, people tend to compare intruding noise with the existing background noise. If the new noise is readily identifiable or considerably louder than the background, it has the potential to be objectionable or annoying (Caltrans 2009). Noise impacts can be broken down into three categories. The first is audible impacts. Audible increases in noise levels generally refer to a change of 3 dBA or more, as this level has been found to be barely perceptible in exterior environments. The second category, potentially audible, refers to a change of between 1 and 3 dBA. This range of noise levels was found to be noticeable to sensitive people in laboratory environments. The last category, inaudible, includes changes of less than 1 dBA, which are typically inaudible to the human ear except under quiet conditions in controlled environments. In general, human sound perception is such that a change in sound level of 3 dB is just noticeable, a change of 5 dB is clearly noticeable, and a change of 10 dB is perceived as doubling or halving of sound level. Only audible changes of 3 dBA or greater in noise levels at sensitive receptors are considered potentially significant when noise levels exceed the compatibility criteria (see Table 6, shown previously). Based on the City of Anaheim’s noise compatibility criteria of 60 dBA CNEL for residential uses, the City considers audible dBA) increases in project-related traffic noise to be substantial when the ambient noise environment along the roadway segments within the project’s study area under with project conditions exceeds 60 dBA CNEL. Stationary-Source Noise The stationary noise thresholds are based on a combination of the human tolerance to noise (see Table 3) and local criteria for stationary noise sources as established by the City of Anaheim for noise control (Anaheim Municipal Code, Chapter 6.70, Sound Pressure Levels). Pursuant to the municipal code, the City restricts noise levels generated at a property from exceeding 60 dBA Leq for extended period of time. 4.3 THE HONDA CENTER Mobile-source noise generated by the proposed project includes noise from vehicles traveling to and from the project site. The proposed project would also result in generation of stationary-source noise which includes noise from heating, ventilation, and air conditioning (HVAC) systems, landscaping activities, truck deliveries, and surface parking lots. 4.3.1 Non-Transportation (Stationary) Sources of Noise Unlike transportation noise sources, whose effects can extend well beyond the limits of the project site, stationary noise only impacts sensitive receptors adjacent to a project site. Stationary sources of noise include mechanical equipment (HVAC systems) and parking lots. The proposed project would not introduce any new or different stationary sources of noise at the project site compared to the types of noise currently generated during a permitted event at the Honda Center. Installation of additional mechanical systems or expansion of the parking lots would not be required. The City of Anaheim restricts stationary noise generated on a property from creating a nuisance to other offsite noise-sensitive receptors through implementation of the noise limits in the City’s municipal code. The proposed project would add approximately 15,000 square feet of restaurant and an approximately 5,000 square-foot team store. There would be no new HVAC units or an expansion of the parking lot as part of the project. While the project may increase parking utilization and cause a marginal increase in the utilization of existing HVAC units, these changes are minimal and therefore the project would not cause discernable noise increases to any noise-sensitive use. No mitigation measures would be required. ---PAGE BREAK--- 4. Environmental Impacts The Honda Center Noise Technical Study City of Anaheim Page 15 4.3.2 Transportation Sources of Noise The operations phase of the project would generate noise primarily associated with vehicular trips. Traffic noise modeling is based on average daily traffic volumes on roadway segments within the analysis conducted by Parsons Brinkerhoff (2012). 2011 Traffic Noise with Project (Sellout Event) Traffic noise modeling was compiled for year 2011No Event and 2011 Plus Project (sellout event), and shown in Table 7. The significance criteria for roadway noise impacts are based on whether the proposed project would result in a substantial increase (3 dB or more) in the ambient noise environment along the roadways when the ambient noise environment exceeds 60 dBA CNEL (daily noise levels). The proposed project would result in similar noise levels along the roadways within the study area of the project, and no traffic noise impacts due to the project would occur.

The proposed project would increase the number of events from an average of 153 events to a maximum of 222 events per year. The significance criteria for roadway noise impacts are based on whether the proposed project would result in a substantial increase (3 dB or more) in the ambient noise environment along the roadways when the ambient noise environment exceeds 60 dBA CNEL (daily noise levels). As shown in Table 1, a full-capacity event at the Honda Center has the potential to generate between 17,174 spectators and 18,900 spectators, and the capacity of the arena would not increase as a result of the proposed project. The events under the proposed project would have similar operational characteristics and seating capacity (18,336) and would generate comparable vehicle trips as current events Anaheim Ducks hockey games, concerts, NCAA basketball games, and NBA exhibition games) at the Honda Center arena. While the number of Honda Center events would increase from an average of 3 events per week to an average of 4 events per week, average daily noise levels generated by an event would not change with the project. The proposed project would result in similar noise levels along the roadways within the study area of the project, and no traffic noise impacts would occur. ---PAGE BREAK--- 4.

Similar to the Existing with Project Event analysis, traffic noise impacts from project-generated traffic under Year 2030 conditions would be comparable to traffic noise impacts of events currently permitted at Honda Center. While audible dB) changes in the noise environment would occur on event days compared to existing non-event days, the project itself would not increase attendance during a Honda Center event and associated traffic levels. Therefore, no project-related traffic noise impacts would occur under Year 2030 conditions. ---PAGE BREAK--- 4.

While concurrent events at the Honda Center and the Angel Stadium of Anaheim generate audible dB) increase in noise levels in year 2030 conditions compared to existing conditions without events, the project would not result in a change in overall attendance at events held at the Honda Center and therefore would not contribute to increases in the ambient noise environment.

Traffic Noise A potentially significant cumulative noise impact to residential areas located east of Sunkist Street between Cerritos Avenue and Ball Road could occur with concurrent scheduling of events at the Honda Center and the Angel Stadium of Anaheim for year 2030 when added to future cumulative development. 4.6 MITIGATION MEASURES Stationary Noise No significant impacts were identified and no mitigation measures are necessary. Traffic Noise MM-1 Prior to issuance of building permits, the project applicant shall contribute fair-share funding to repave Sunkist Street between Cerritos Avenue and Ball Road with rubberized asphalt. Studies have shown that asphalt rubber overlays resulted in a reduction in road noise in the order of 6 dB. (Rymer and Donavan, 2005) 4.7 LEVEL OF SIGNIFICANCE AFTER MITIGATION No significant project-related impacts have been identified. With implementation of MM-1, cumulative noise impacts would be less than significant. ---PAGE BREAK--- 4.
