Agenda packet — Bellflower City Council, September 26, 2022 (part 2 of 4)

SCAG RTP/SCS Consistency

On September 3, 2020, SCAG’s Regional Council adopted Connect SoCal (2020 – 2045 Regional Transportation Plan/Sustainable Communities Strategy [2020 RTP/SCS]). The RTP/SCS is a long-range visioning plan that balances future mobility and housing needs with economic, environmental, and public health goals. The RTP/SCS embodies a collective vision for the region’s future and is developed with input from local governments, county transportation commissions, tribal governments, nonprofit organizations, businesses, and local stakeholders in the counties of Imperial, Los Angeles, Orange, Riverside, San Bernardino, and Ventura. SCAG’s RTP/SCS establishes GHG emissions goals for automobiles and light-duty trucks for 2020 and 2035 as well as an overall GHG target for the Project region consistent with both the target date of AB 32 and the post-2020 GHG reduction goals of Executive Orders 5-03-05 and B-30-15.

The RTP/SCS contains over 4,000 transportation projects, ranging from highway improvements, railroad grade separations, bicycle lanes, new transit hubs and replacement bridges. These future investments were included in county plans developed by the six county transportation commissions and seek to reduce traffic bottlenecks, improve the efficiency of the region’s network, and expand mobility choices for everyone. The RTP/SCS is an important planning document for the region, allowing project sponsors to qualify for federal funding.

The plan accounts for operations and maintenance costs to ensure reliability, longevity, and cost effectiveness. The RTP/SCS is also supported by a combination of transportation and land use strategies

that help the region achieve state GHG emissions reduction goals and Federal Clean Air Act (FCAA) requirements, preserve open space areas, improve public health and roadway safety, support our vital goods movement industry, and utilize resources more efficiently. GHG emissions resulting from development-related mobile sources are the most potent source of emissions, and therefore Project comparison to the RTP/SCS is an appropriate indicator of whether the Project would inhibit the post-2020 GHG reduction goals promulgated by the state. The Project’s consistency with the RTP/SCS goals is analyzed in detail in Table 5: Regional Transportation Plan/Sustainable Communities Strategy Consistency.

Table 5: Regional Transportation Plan/Sustainable Communities Strategy Consistency SCAG Goals Compliance
GOAL 1: Encourage regional economic prosperity
and global competitiveness.

N/A: This is not a project-specific policy and is therefore not applicable. However, the Project is located on a
vacant site and development of the site would
contribute to regional economic prosperity.

GOAL 2: Improve mobility, accessibility, reliability,
and travel safety for people and goods.

N/A: This is not a transportation improvement project and is therefore not applicable.

GOAL 3: Enhance the preservation, security, and
resilience of the regional transportation
system.

N/A: This is not a transportation improvement project and is therefore not applicable.

GOAL 4: Increase person and goods movement and
travel choices within the transportation
system.

N/A: This is not a transportation improvement project and is therefore not applicable.

GOAL 5: Reduce greenhouse gas emissions and
improve air quality.

Consistent: The Project is located within an urban area in proximity to existing transportation routes and
freeways. Location of the project within a developed
area would reduce trip lengths, which would reduce
GHG and air quality emissions.

GOAL 6: Support healthy and equitable communities Consistent: The Project does not exceed localized thresholds.

Based on the Friant Ranch decision, projects that do
not exceed the SCAQMD’s LSTs would not violate any
air quality standards or contribute substantially to an existing or projected air quality violation and result
in no criteria pollutant health impacts.

GOAL 7: Adapt to a changing climate and support an
integrated regional development pattern
and transportation network.

N/A: This is not a project-specific policy and is therefore not applicable.

GOAL 8: Leverage new transportation technologies
and data-driven solutions that result in
more efficient travel.

N/A: This is not a project-specific policy and is therefore not applicable.

GOAL 9: Encourage development of diverse housing
types in areas that are supported by
multiple transportation options.

N/A: The Project involves development of restaurants and retail but does not include housing. The Project is
located within a relatively short walking distance to
local bus routes.

GOAL 10: Promote conservation of natural and
agricultural lands and restoration of
habitats.

N/A: The Project is located on a vacant land and is not located on agricultural lands.

Compliance with applicable State standards would ensure consistency with State and regional GHG reduction planning efforts. The goals stated in the RTP/SCS were used to determine consistency with the planning efforts previously stated. As shown in Table 5, the proposed Project would be consistent with the stated goals of the RTP/SCS. Therefore, the proposed Project would not result in any significant impacts or interfere with SCAG’s ability to achieve the region’s post-2020 mobile source GHG reduction targets.

Consistency with the CARB Scoping Plan

The California State Legislature adopted AB 32 in 2006. AB 32 focuses on reducing GHGs (CO 2, CH4, N2O, HFCs, PFCs, and SF6) to 1990 levels by the year 2020. Pursuant to the requirements in AB 32, CARB adopted the Climate Change Scoping Plan (Scoping Plan) in 2008, which outlines actions recommended to obtain that goal. The Scoping Plan provides a range of GHG reduction actions that include direct regulations, alternative compliance mechanisms, monetary and non-monetary incentives, voluntary actions, market- based mechanisms such as the cap-and-trade program, and an AB 32 implementation fee to fund the program. The 2017 Scoping Plan Update identifies additional GHG reduction measures necessary to achieve the 2030 target. These measures build upon those identified in the first update to the Scoping Plan in 2013. Although a number of these measures are currently established as policies and measures, some measures have not yet been formally proposed or adopted. It is expected that these actions to reduce GHG emissions will be adopted as required to achieve statewide GHG emissions targets.

As shown in Table 6: Project Consistency with Applicable CARB Scoping Plan Measures, the Project is consistent with most of the strategies, while others are not applicable to the Project. As such, impacts related to consistency with the Scoping Plan would be less than significant.

regulation indirectly affects people who use the
products and services produced by these industrial
sources when increased cost of products or services
(such as electricity and fuel) are transferred to the
consumers. The Cap-and-Trade Program covers the
GHG emissions associated with electricity consumed in
California, generated in-state or imported.

Accordingly, GHG emissions associated with CEQA
projects’ electricity usage are covered by the Cap-and- Trade Program. The Cap-and-Trade Program also
covers fuel suppliers (natural gas and propane fuel
providers and transportation fuel providers) to address emissions from such fuels and combustion of other
fossil fuels not directly covered at large sources in the Program’s first compliance period.

As seen in Tables 4 through Table 6, the Project would be consistent with all applicable GHG reduction plan goals. In addition, as shown in Table 3, the Project’s long-term operational emissions would not exceed the City’s GHG threshold of 3,000 MTCO2e. Regarding goals for 2050 under Executive Order S-3- 05, at this time it is not possible to quantify the emissions savings from future regulatory measures, as they have not yet been developed; nevertheless, it can be anticipated that operation of the proposed Project would benefit from the implementation of current and potential future regulations (e.g., improvements in vehicle emissions, SB 100/renewable electricity portfolio improvements, etc.) enacted to meet an 80 percent reduction below 1990 levels by 2050.

The majority of the GHG reductions from the Scoping Plan would result from continuation of the Cap-and- Trade regulation. Assembly Bill 398 (2017) extends the state’s Cap-and-Trade program through 2030 and the Scoping Plan provide a comprehensive plan for the state to achieve its GHG targets through a variety of regulations enacted at the state level. Additional reductions are achieved from electricity sector standards (i.e., utility providers to supply 60 percent renewable electricity by 2030 and 100 percent renewable by 2045), doubling the energy efficiency savings at end uses, additional reductions from the LCFS, implementing the short-lived GHG strategy (e.g., hydrofluorocarbons), and implementing the Mobile Source Strategy and Sustainable Freight Action Plan.

Several of the State’s plans and policies would contribute to a reduction in mobile source emissions from the Project. These include CARB’s Advanced Clean Truck Regulation, Executive Order N-79-20, CARB’s Mobile Source Strategy, CARB’s Sustainable Freight Action Plan, and CARB’s Emissions Reduction Plan for Ports and Goods Movement. CARB’s Advanced Clean Truck Regulation requires truck manufacturers to transition from diesel trucks and vans to electric zero-emission trucks beginning in 2024. By 2045, every new truck sold in California is required to be zero-emission. The Advanced Clean Truck Regulation accelerates the transition of zero-emission medium-and heavy-duty vehicles from Class 2b to Class 8.

Executive Order N-79-20 establishes the goal for all new passenger cars and trucks, as well as all drayage/cargo trucks and off-road vehicles and equipment, sold in California, will be zero-emission by 2035 and all medium and heavy-duty vehicles will be zero-emission by 2045. It also directs CARB to develop and propose rulemaking for passenger vehicles and trucks, medium-and heavy-duty fleets where feasible, drayage trucks, and off-road vehicles and equipment “requiring increasing volumes” of new ZEVs “towards the target of 100 percent.”
CARB’s Mobile Source Strategy includes increasing ZEV buses and trucks and their Sustainable Freight Action Plan improves freight system efficiency, utilizes near-zero emissions technology, and deployment of ZEV trucks. This Plan applies to all trucks accessing the Project site and may include existing trucks or new trucks that are part of the statewide goods movement sector. CARB’s Emissions Reduction Plan for Ports and Goods Movement identifies measures to improve goods movement efficiencies such as advanced combustion strategies, friction reduction, waste heat recovery, and electrification of accessories. While these measures are not directly applicable to the Project, any commercial activity associated with goods movement would be required to comply with these measures as adopted.

The Project would not obstruct or interfere with efforts to increase ZEVs or state efforts to improve system efficiency. The Project’s long-term operational and short-term construction GHG emissions would not exceed the SCAQMD threshold of 3,000 MTCO2e per year. Additionally, the Project would be consistent with applicable regulations and goals. Therefore, the Project would have a less than significant impact.

Mitigation Measures: No mitigation is required.

Level of Significance: Less than significant impact.

5.3 Cumulative Setting, Impacts, and Mitigation Measures

Cumulative Setting

Climate change is a global problem. GHGs are global pollutants, unlike criteria air pollutants and TACs, which are pollutants of regional and local concern. Whereas pollutants with localized air quality effects have relatively short atmospheric lifetimes (about 1 day), GHGs have much longer atmospheric lifetimes of 1 year to several thousand years that allow them to be dispersed around the globe.

City of Bellflower Bellflower Convenience Center
Greenhouse Gas Emissions Assessment

Page | 32

Cumulative Impacts

It is generally the case that an individual project of this size and nature is of insufficient magnitude by itself to influence climate change or result in a substantial contribution to the global GHG inventory. GHG impacts are recognized as exclusively cumulative impacts; there are no non-cumulative GHG emission impacts from a climate change perspective. The additive effect of Project-related GHGs would not result in a reasonably foreseeable cumulatively considerable contribution to global climate change. As discussed above, Project-related GHG emissions would not exceed the City’s threshold of 3,000 MTCO2e. Therefore, the Project would result in a less than significant cumulative GHG impact.

Mitigation Measures: No mitigation is required.

Level of Significance: Less than significant impact.

1 INTRODUCTION

This report documents the results of an Acoustical Assessment completed for the Bellflower Convenience Center Project (“Project” or “Proposed Project”). The purpose of this Acoustical Assessment is to evaluate the potential construction and operational noise and vibration levels associated with the Project and determine the level of impact the Project would have on the environment.

1.1 Project Location and Setting

The Project site is located in southern Bellflower, in Los Angeles County (County), California; refer to Exhibit 1: Regional Vicinity. The proposed Project site is located at 17671 Bellflower Boulevard, on the west side of Bellflower Boulevard, between Cedar Street and Ramona Street, in the City of Bellflower. The Project site is bounded by Ramona Street and commercial uses to the north, Cedar Street, commercial uses, and residential uses to the south, Bellflower Boulevard and commercial uses to the east, and residential and commercial uses to the west; see Exhibit 2: Site Vicinity.

The Project site is a vacant rectangular-shaped site on 3.63 acres. Previously, there was an automotive dealership, a restaurant, and other commercial/retails buildings on the Project Site. These buildings were demolished at the end of 2017. The Project site is currently vacant and shows signs of ruderal grasses, but no native habitat remains on-site. The Project site has a General Plan land use designation of Commercial (C) and is zoned DFD (Design for Development).

1.2 Project Description

The proposed Project is a commercial development composed of a shopping center. This would include a convenience store and automotive fueling station, three drive-thru quick-serve restaurants, and one retail building for multiple tenants; refer to Exhibit 3: Conceptual Site Plan.

Building 1: Restaurant
The proposed Project consists of the construction of a new one-story drive-thru restaurant totaling approximately 3,164-square feet (sf). The restaurant would be located on the southern portion of the overall Project site. The main entrance for guests would be provided on the north side of the building via an entrance to the building. The drive through portion would have an entrance on the western side of the building and exit on the eastern side of the building. There would also be an outdoor seating area of approximately 464 sf on the eastern side of the building.

Building 2: Restaurant
The proposed Building 2 would be a new one-story drive through restaurant totaling approximately 2,378 sf. The restaurant would be located on the southern portion of the overall Project site. The main entrance for guests would be provided on western side of the building via an entrance to the building. The drive through portion would have an entrance on the northern side of the building and exit on the southern side of the building. There would also be an outdoor seating area of approximately 185 sf on the eastern side of the building.

Building 3: Restaurant
The proposed Building 3 would be a new one-story drive through restaurant totaling approximately 2,509 sf. The restaurant would be located in the center of the overall Project site. The main entrance for guests would be provided on the northern side of the building via an entrance to the building. The drive through portion would have an entrance on the western side of the building and exit on the southern side of the building. There would also be an outdoor seating area of approximately 544 sf on the eastern side of the building.

Building 4: Retail
The proposed Building 4 would be a one-story, approximately 3,997 sf, gas station convenience store with eight fueling pumps. The proposed building would be generally located on the northern portion of the site. The main entrance would be located on the eastern side of the building and the fueling pumps would be to the east of the building.

Building 5: Retail
The proposed Building 5 would be an approximately 8,356 sf retail building with space for multiple tenants. This proposed building would be generally located on the northwestern portion of the overall site. The main entrance would be located on the northeastern side of the building.

Project Circulation
Ingress and egress to the site would be provided via five driveways in total. Three driveways would be on Bellflower Boulevard, two of these driveways would be 30’ and the driveway closes to the proposed gas station would be 35’. A 26’ driveway would be on Cedar Street and another 35’ driveway would be on Ramona Street, directly to the north of the proposed gas station. All driveways would allow access to the entire Project site.

Parking
The Project would provide 132 parking stalls, with vehicle parking located throughout the site and between the various establishments.

Project Phasing and Construction
The Project is anticipated to be developed in one phase. Should the Project be approved, construction is anticipated to occur over a duration of approximately 11 months, beginning in February 2023 and completed by the end of January 2024.

2 ACOUSTIC FUNDAMENTALS

2.1 Sound and Environmental Noise

Acoustics is the science of sound. Sound can be described as the mechanical energy of a vibrating object transmitted by pressure waves through a medium (e.g., air) to human (or animal) ear. If the pressure variations occur frequently enough (at least 20 times per second), they can be heard and are called sound.

The number of pressure variations per second is called the frequency of sound and is expressed as cycles per second, or hertz (Hz).

Noise is defined as loud, unexpected, or annoying sound. In acoustics, the fundamental model consists of a noise source, a receptor, and the propagation path between the two. The loudness of the noise source, obstructions, or atmospheric factors affecting the propagation path, determine the perceived sound level and noise characteristics at the receptor. Acoustics deal primarily with the propagation and control of sound. A typical noise environment consists of a base of steady background noise that is the sum of many distant and indistinguishable noise sources. Superimposed on this background noise is the sound from individual local sources. These sources can vary from an occasional aircraft or train passing by to continuous noise from traffic on a major highway. Perceptions of sound and noise are highly subjective from person to person.

Measuring sound directly in terms of pressure would require a large range of numbers. To avoid this, the decibel (dB) scale was devised. The dB scale uses the hearing threshold of 20 micropascals (µPa) as a point of reference, defined as 0 dB. Other sound pressures are then compared to this reference pressure, and the logarithm is taken to keep the numbers in a practical range. The dB scale allows a million-fold increase in pressure to be expressed as 120 dB, and changes in levels correspond closely to human perception of relative loudness. Table 1: Typical Noise Levels provides typical noise levels.

Noise Descriptors

The dB scale alone does not adequately characterize how humans perceive noise. The dominant frequencies of a sound have a substantial effect on the human response to that sound. Several rating scales have been developed to analyze the adverse effect of community noise on people. Because environmental noise fluctuates over time, these scales consider that the effect of noise on people is largely dependent on the total acoustical energy content of the noise, as well as the time of day when the noise occurs. The equivalent noise level (Leq) represents the continuous sound pressure level over the measurement period, while the day-night noise level (Ldn) and Community Equivalent Noise Level (CNEL) are measures of energy average during a 24-hour period, with dB weighted sound levels from 7:00 p.m. to 7:00 a.m. Most commonly, environmental sounds are described in terms of Leq that has the same acoustical energy as the summation of all the time-varying events. Each is applicable to this analysis and defined in Table 2: Definitions of Acoustical Terms.

Table 2: Definitions of Acoustical Terms
Term Definitions
Decibel (dB) A unit describing the amplitude of sound, equal to 20 times the logarithm to the base 10 of the ratio of the pressure of the sound measured to the reference pressure. The reference pressure for air is 20.

Sound Pressure Level Sound pressure is the sound force per unit area, usually expressed in µPa (or 20 micronewtons per square meter), where 1 pascals is the pressure resulting from a force of 1 newton exerted over an area of 1 square meter. The sound pressure level is expressed in dB as 20 times the logarithm to the base 10 of the ratio between the pressures exerted by the sound to a reference sound pressure (e.g., 20 µPa). Sound pressure level is the quantity that is directly measured by a sound level meter.

Frequency (Hz) The number of complete pressure fluctuations per second above and below atmospheric pressure. Normal human hearing is between 20 Hz and 20,000 Hz. Infrasonic sound are below 20 Hz and ultrasonic sounds are above 20,000 Hz.

A-Weighted Sound Level (dBA) The sound pressure level in dB as measured on a sound level meter using the A-weighting filter network. The A-weighting filter de-emphasizes the very low and very high frequency components of the sound in a manner similar to the frequency response of the human ear and correlates well with subjective reactions to noise.

Equivalent Noise Level (Leq) The average acoustic energy content of noise for a stated period of time. Thus, the L eq of a time-varying noise and that of a steady noise are the same if they deliver the same acoustic energy to the ear during exposure. For evaluating community impacts, this rating scale does not vary, regardless of whether the noise occurs during the day or the night.

Maximum Noise Level (Lmax)
Minimum Noise Level (Lmin)
The maximum and minimum dBA during the measurement period.

Exceeded Noise Levels
(L01, L10, L50, L90)
The dBA values that are exceeded 1%, 10%, 50%, and 90% of the time during the measurement period.

Day-Night Noise Level (Ldn) A 24-hour average Leq with a 10 dBA weighting added to noise during the hours of 10:00 p.m. to 7:00 a.m. to account for noise sensitivity at nighttime. The logarithmic effect of these additions is that a 60 dBA 24-hour Leq would result in a measurement of 66.4 dBA Ldn.

Community Noise Equivalent
Level (CNEL)
A 24-hour average Leq with a 5 dBA weighting during the hours of 7:00 a.m. to 10:00 a.m. and a 10 dBA weighting added to noise during the hours of 10:00 p.m. to 7:00 a.m. to account for noise sensitivity in the evening and nighttime, respectively. The logarithmic effect of these additions is that a 60 dBA 24-hour Leq would result in a measurement of 66.7 dBA CNEL.

Ambient Noise Level The composite of noise from all sources near and far. The normal or existing level of environmental noise at a given location.

Intrusive That noise which intrudes over and above the existing ambient noise at a given location.

The relative intrusiveness of a sound depends on its amplitude, duration, frequency, and time of occurrence and tonal or informational content as well as the prevailing ambient noise level.

The A-weighted decibel (dBA) sound level scale gives greater weight to the frequencies of sound to which the human ear is most sensitive. Because sound levels can vary markedly over a short period of time, a method for describing either the average character of the sound or the statistical behavior of the variations must be utilized. Most commonly, environmental sounds are described in terms of an average level that has the same acoustical energy as the summation of all the time-varying events.

The scientific instrument used to measure noise is the sound level meter. Sound level meters can accurately measure environmental noise levels to within about plus or minus 1 dBA. Various computer models are used to predict environmental noise levels from sources, such as roadways and airports. The accuracy of the predicted models depends on the distance between the receptor and the noise source.

A-Weighted Decibels

The perceived loudness of sounds is dependent on many factors, including sound pressure level and frequency content. However, within the usual range of environmental noise levels, perception of loudness is relatively predictable and can be approximated by dBA values. There is a strong correlation between dBA and the way the human ear perceives sound. For this reason, the dBA has become the standard tool of environmental noise assessment. All noise levels reported in this document are in terms of dBA, but are expressed as dB, unless otherwise noted.

Addition of Decibels

The dB scale is logarithmic, not linear, and therefore sound levels cannot be added or subtracted through ordinary arithmetic. Two sound levels 10 dB apart differ in acoustic energy by a factor of 10. When the standard logarithmic dB is A-weighted, an increase of 10 dBA is generally perceived as a doubling in loudness. For example, a 70-dBA sound is half as loud as an 80-dBA sound and twice as loud as a 60-dBA sound. When two identical sources are each producing sound of the same loudness, the resulting sound level at a given distance would be 3 dBA higher than one source under the same conditions. Under the dB scale, three sources of equal loudness together would produce an increase of 5 dBA.

Sound Propagation and Attenuation

Sound spreads (propagates) uniformly outward in a spherical pattern, and the sound level decreases (attenuates) at a rate of approximately 6 dB for each doubling of distance from a stationary or point source. Sound from a line source, such as a highway, propagates outward in a cylindrical pattern. Sound levels attenuate at a rate of approximately 3 dB for each doubling of distance from a line source, such as a roadway, depending on ground surface characteristics. No excess attenuation is assumed for hard surfaces like a parking lot or a body of water. Soft surfaces, such as soft dirt or grass, can absorb sound, so an excess ground-attenuation value of 1.5 dB per doubling of distance is normally assumed. For line sources, an overall attenuation rate of 3 dB per doubling of distance is assumed.

Noise levels may also be reduced by intervening structures; generally, a single row of buildings between the receptor and the noise source reduces the noise level by about 5 dBA, while a solid wall or berm reduces noise levels by 5 to 10 dBA. The way older homes in California were constructed generally provides a reduction of exterior-to-interior noise levels of about 20 to 25 dBA with closed windows. The exterior-to-interior reduction of newer residential units is generally 30 dBA or more.

Human Response to Noise

The human response to environmental noise is subjective and varies considerably from individual to individual. Noise in the community has often been cited as a health problem, not in terms of actual physiological damage, such as hearing impairment, but in terms of inhibiting general well-being and contributing to undue stress and annoyance. The health effects of noise in the community arise from interference with human activities, including sleep, speech, recreation, and tasks that demand concentration or coordination. Hearing loss can occur at the highest noise intensity levels.

Noise environments and consequences of human activities are usually well represented by median noise levels during the day or night or over a 24-hour period. Environmental noise levels are generally considered low when the CNEL is below 60 dBA, moderate in the 60 to 70 dBA range, and high above 70 dBA. Examples of low daytime levels are isolated, natural settings with noise levels as low as 20 dBA and quiet, suburban, residential streets with noise levels around 40 dBA. Noise levels above 45 dBA at night can disrupt sleep. Examples of moderate-level noise environments are urban residential or semi- commercial areas (typically 55 to 60 dBA) and commercial locations (typically 60 dBA). People may consider louder environments adverse, but most will accept the higher levels associated with noisier urban residential or residential-commercial areas (60 to 75 dBA) or dense urban or industrial areas (65 to 80 dBA). Regarding increases in dBA, the following relationships should be noted:

 Except in carefully controlled laboratory experiments, a 1-dBA change cannot be perceived by humans.
 Outside of the laboratory, a 3-dBA change is considered a just-perceivable difference.  A minimum 5-dBA change is required before any noticeable change in community response would be expected. A 5-dBA increase is typically considered substantial.  A 10-dBA change is subjectively heard as an approximate doubling in loudness and would almost certainly cause an adverse change in community response.

Effects of Noise on People

Hearing Loss. While physical damage to the ear from an intense noise impulse is rare, a degradation of auditory acuity can occur even within a community noise environment. Hearing loss occurs mainly due to chronic exposure to excessive noise but may be due to a single event such as an explosion. Natural hearing loss associated with aging may also be accelerated from chronic exposure to loud noise. The Occupational Safety and Health Administration has a noise exposure standard that is set at the noise threshold where hearing loss may occur from long-term exposures. The maximum allowable level is 90 dBA averaged over 8 hours. If the noise is above 90 dBA, the allowable exposure time is correspondingly shorter.

Annoyance. Attitude surveys are used for measuring the annoyance felt in a community for noises intruding into homes or affecting outdoor activity areas. In these surveys, it was determined that causes for annoyance include interference with speech, radio and television, house vibrations, and interference with sleep and rest. The Ldn as a measure of noise has been found to provide a valid correlation of noise level and the percentage of people annoyed. People have been asked to judge the annoyance caused by aircraft noise and ground transportation noise. There continues to be disagreement about the relative

Page | 10
annoyance of these different sources. A noise level of about 55 dBA Ldn is the threshold at which a substantial percentage of people begin to report annoyance.1

2.2 Groundborne Vibration

Sources of groundborne vibrations include natural phenomena (earthquakes, volcanic eruptions, sea waves, landslides, etc.) or man-made causes (explosions, machinery, traffic, trains, construction equipment, etc.). Vibration sources may be continuous (e.g., factory machinery) or transient (e.g., explosions). Ground vibration consists of rapidly fluctuating motions or waves with an average motion of zero. Several different methods are typically used to quantify vibration amplitude. One is the peak particle velocity (PPV); another is the root mean square (RMS) velocity. The PPV is defined as the maximum instantaneous positive or negative peak of the vibration wave. The RMS velocity is defined as the average of the squared amplitude of the signal. The PPV and RMS vibration velocity amplitudes are used to evaluate human response to vibration.

Table 3: Human Reaction and Damage to Buildings for Continuous or Frequent Intermittent Vibrations, displays the reactions of people and the effects on buildings produced by continuous vibration levels. The annoyance levels shown in the table should be interpreted with care since vibration may be found to be annoying at much lower levels than those listed, depending on the level of activity or the sensitivity of the individual. To sensitive individuals, vibrations approaching the threshold of perception can be annoying.

Low-level vibrations frequently cause irritating secondary vibration, such as a slight rattling of windows, doors, or stacked dishes. The rattling sound can give rise to exaggerated vibration complaints, even though there is very little risk of actual structural damage. In high noise environments, which are more prevalent where groundborne vibration approaches perceptible levels, this rattling phenomenon may also be produced by loud airborne environmental noise causing induced vibration in exterior doors and windows.

Ground vibration can be a concern in instances where buildings shake, and substantial rumblings occur.

However, it is unusual for vibration from typical urban sources such as buses and heavy trucks to be perceptible. Common sources for groundborne vibration are planes, trains, and construction activities such as earth-moving which requires the use of heavy-duty earth moving equipment. For the purposes of this analysis, a PPV descriptor with units of inches per second (in/sec) is used to evaluate construction- generated vibration for building damage and human complaints.

3 REGULATORY SETTING

To limit population exposure to physically or psychologically damaging as well as intrusive noise levels, the Federal government, the State of California, various county governments, and most municipalities in the state have established standards and ordinances to control noise.

3.1 State of California

California Government Code

California Government Code Section 65302(f) mandates that the legislative body of each county and city adopt a noise element as part of its comprehensive general plan. The local noise element must recognize the land use compatibility guidelines established by the State Department of Health Services. The guidelines rank noise land use compatibility in terms of “normally acceptable”, “conditionally acceptable”, “normally unacceptable”, and “clearly unacceptable” noise levels for various land use types. Single-family homes are “normally acceptable” in exterior noise environments up to 60 CNEL and “conditionally acceptable” up to 70 CNEL. Multiple-family residential uses are “normally acceptable” up to 65 CNEL and “conditionally acceptable” up to 70 CNEL. Schools, libraries, and churches are “normally acceptable” up to 70 CNEL, as are office buildings and business, commercial, and professional uses.

Title 24 – Building Code

The State’s noise insulation standards are codified in the California Code of Regulations, Title 24: Part 1, Building Standards Administrative Code, and Part 2, California Building Code. These noise standards are applied to new construction in California for 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 65 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. For new multi-family residential buildings, the acceptable interior noise limit for new construction is 45 dBA CNEL.

3.2 Local

City of Bellflower General Plan

Adopted in 1994, the Bellflower General Plan 1995 – 2010 (Bellflower General Plan) identifies noise sources and goals and polices related to noise. The Bellflower General Plan identifies automobiles as the majority of noise in the City. Other significant sources of noise come from incompatible land uses.

Land uses near these significant noise-producers can incorporate buffers and noise control techniques including setbacks, landscaping, building transitions, site design, and building construction techniques to reduce the impact of excessive noise. Selection of the appropriate noise control technique would vary depending on the level of noise that needs to be reduced as well as the location and intended land use.

Additionally, the Noise Element identifies transportation noise policies designed to protect, create, and maintain an environment free of harmful noise that could impact the health and welfare of sensitive

receptors. The following Bellflower General Plan goals, policies, and actions for addressing noise are applicable to the Project:

Goal 1: Maintain or reduce noise levels throughout the City.

Policy 1.4: Limit construction activities which impact adjacent residential uses to the hours of 7 a.m. to 8 p.m. during weekdays and Saturdays.

Policy 1.5: Require construction activities to incorporate feasible and practical techniques which minimize noise impacts on adjacent areas.

Policy 1.7: Ensure the outdoor noise limits for residential uses do no exceed 60 dB CNEL for single family uses and 65 dB Ldn for multiple family uses.

Goal 2: Protect residential and other sensitive land uses from the exposure of commercial and industrially-generated noise.

Policy 2.2: Use design standards and other mechanisms to contain noise generated by commercial and industrial land uses on site.

The Bellflower General Plan also employs land use compatibility guidelines for noise and are used for planning purposes. These guidelines are based in part on the community noise compatibility guidelines established by the California State Governor’s Office of Planning and Research and are intended for use in assessing the compatibility of various land use types with a range of noise levels. Table 5: Guidelines for Noise Compatible Uses provides the guidelines of land use compatibility for community noise sources.

The CNEL noise levels for specific land uses are classified into four categories: (1) “normally acceptable” (2) “conditionally acceptable” (3) “normally unacceptable” and (4) “clearly unacceptable.” A CNEL value of 70 dBA is considered the dividing line between a “conditionally acceptable” and “normally unacceptable” noise environment for noise sensitive land uses, including residences, transient lodgings, schools, and library.

City of Bellflower Municipal Code

Standards established under the City of Bellflower Municipal Code (Bellflower Municipal Code) are used to analyze noise impacts originating from the Project. Operational noise impacts are typically governed by Bellflower Municipal Code Sections 8.32.010 through 8.32.020. Guidelines for non-transportation and stationary noise source impacts from operations at private properties are found in Title 17 in the Bellflower Municipal Code. Applicable guidelines indicate that no person shall create or cause unreasonable noise level within 200 feet from the property line of a noise source in a residential area or zone, or within 500 feet of any residential zone.

The City of Bellflower has also adopted the California Building Code (CBC) in Chapter 15.04 of the Bellflower Municipal Code, which limits construction activities to the hours of 7:00 a.m. and 6:00 p.m.

Monday through Friday, 8:00 a.m. and 6:00 p.m. on Saturdays; construction is prohibited on Sundays and City holidays.

4 EXISTING CONDITIONS

4.1 Existing Noise Sources

The City is impacted by various noise sources. Mobile sources of noise, especially cars, trucks, and trains are the most common and significant sources of noise. Other noise sources are the various land uses (i.e., residential, commercial, institutional, and recreational and parks activities) throughout the City that generate stationary-source noise.

Mobile Sources

Existing roadway noise levels were calculated for the roadway segments in the Project vicinity. This task was accomplished using the Federal Highway Administration (FHWA) Highway Traffic Noise Prediction Model (FHWA-RD-77-108) and traffic data from the Project’s Traffic Impact Analysis (Kimley-Horn and Associates, February 2022). The noise prediction model calculates the average noise level at specific locations based on traffic volumes, average speeds, roadway geometry, and site environmental conditions. The average vehicle noise rates (also referred to as energy rates) used in the FHWA model have been modified to reflect average vehicle noise rates identified for California by the California Department of Transportation (Caltrans). The Caltrans data indicates that California automobile noise is

0.8 to 1.0 dBA higher than national levels and that medium and heavy truck noise is 0.3 to 3.0 dBA lower than national levels. The average daily noise levels along roadway segments in proximity to the Project site are included in Table 6: Existing Traffic Noise Levels. As shown in Table 6, existing traffic noise levels in the Project vicinity range between 66.7 dBA CNEL and 68.3 dBA CNEL.

Stationary Sources

The primary sources of stationary noise in the Project vicinity are those associated with the restaurant and retail uses to the north and east, and residential properties to the northwest, west and southwest of the Project site. The noise associated with these sources may represent a single-event noise occurrence Table 6: Existing Traffic Noise Levels

or short-term noise. Other noises include mechanical equipment (e.g., heating ventilation and air conditioning [HVAC] equipment), parking lot activities, dogs barking, idling vehicles, and residents talking.

4.2 Noise Measurements

The Project site is currently vacant with adjacent residential uses to the northwest, west, and southwest.

To quantify existing ambient noise levels in the Project area, Kimley-Horn conducted four short-term noise measurements on February 2, 2022; see Appendix A: Existing Ambient Noise Measurements. The noise measurement sites were representative of typical existing noise exposure within and immediately adjacent to the Project site. The 10-minute measurements were taken between 8:55 a.m. and 9:43 a.m.

Measurements of Leq are considered representative of the noise levels throughout the day. The average noise levels and sources of noise measured at each location are listed in Table 7: Existing Noise Measurements and shown on Exhibit 4: Noise Measurement Locations.

4.3 Sensitive Receptors

Sensitive populations are more susceptible to the effects of air pollution than is the general population.

Noise sensitive uses typically include residences, hospitals, schools, childcare facilities, and places of assembly. Sensitive land uses surrounding the Project consist mostly of residential communities. Table 8:

5 SIGNIFICANCE CRITERIA AND METHODOLOGY

5.1 CEQA Thresholds

Appendix G of the California Environmental Quality Act (CEQA) Guidelines contains analysis guidelines related to noise impacts. These guidelines have been used by the City to develop thresholds of significance for this analysis. A project would create a significant environmental impact if it would:

 Generate 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;
 Generate excessive groundborne vibration or groundborne noise levels; and  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, expose people residing or working in the Project area to excessive noise levels.

5.2 Methodology

Construction

Construction noise levels were based on typical noise levels generated by construction equipment published by the Federal Transit Administration (FTA) and FHWA. Construction noise is assessed in dBA Leq. This unit is appropriate because Leq can be used to describe noise level from operation of each piece of equipment separately, and levels can be combined to represent the noise level from all equipment operating during a given period.

FHWA’s Roadway Construction Noise Model (RCNM) was used to estimate construction noise at nearby sensitive receptors. For modeling purposes, construction equipment has been distributed evenly between the center of the construction site and the nearest receptor. To be conservative, the loudest and most used equipment was placed nearest the sensitive receptor. Noise level estimates do not account for the presence of intervening structures or topography, which may reduce noise levels at receptor locations.

Therefore, the noise levels presented herein represent a conservative, reasonable worst-case estimate of actual temporary construction noise.

Operations

The analysis of the Without Project and With Project noise environments is based on noise prediction modeling and empirical observations. Reference noise level data are used to estimate the Project operational noise impacts from stationary sources. Noise levels are collected from field noise measurements and other published sources from similar types of activities are used to estimate noise levels expected with the Project’s stationary sources. The reference noise levels are used to represent a worst-case noise environment as noise level from stationary sources can vary throughout the day.

Operational noise is evaluated based on the standards within the Bellflower Municipal Code and General Plan. The Without Project and With Project traffic noise levels in the Project vicinity were calculated using the FHWA Highway Noise Prediction Model (FHWA-RD-77-108).

Vibration

Ground-borne vibration levels associated with construction-related activities for the Project were evaluated utilizing typical ground-borne vibration levels associated with construction equipment, obtained from FTA published data for construction equipment. Potential ground-borne vibration impacts related to building/structure damage and interference with sensitive existing operations were evaluated, considering the distance from construction activities to nearby land uses and typically applied criteria for structural damage and human annoyance.

6 POTENTIAL IMPACTS AND MITIGATION

6.1 Acoustical Impacts

Threshold 6.1 Would the project generate 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?

Construction

Construction noise typically occurs intermittently and varies depending on the nature or phase of construction (e.g., land clearing, grading, excavation, paving). Noise generated by construction equipment, including earth movers, material handlers, and portable generators, can reach high levels.

During construction, exterior noise levels could affect the residential neighborhoods surrounding the construction site. However, it is acknowledged that construction activities would occur throughout the Project site and would not be concentrated at a single point near sensitive receptors.

Construction activities would include demolition, site preparation, grading, building construction, paving, and architectural coating. Such activities would require industrial saws, excavators, and dozers for demolition; dozers and tractors during site preparation; excavators, graders, dozers, and tractors during grading; cranes, forklifts, generators, tractors, and welders during building construction; pavers, rollers, mixers, and paving equipment during paving; and air compressors during architectural coating. Typical operating cycles for these types of construction equipment may involve 1 or 2 minutes of full power operation followed by 3 to 4 minutes at lower power settings. Other primary sources of acoustical disturbance would be random incidents, which would last less than one minute (such as dropping large pieces of equipment or the hydraulic movement of machinery lifts). Noise generated by construction equipment, including earth movers, material handlers, and portable generators, can reach high levels.

Typical noise levels associated with individual construction equipment are listed in Table 9: Typical Construction Noise Levels.

Source: Federal Transit Administration, Transit Noise and Vibration Impact Assessment Manual, September 2018.

Following the methodology for quantitative construction noise assessments in the FTA’s Transit Noise and Vibration Impact Assessment Manual (September 2018) (FTA Noise and Vibration Manual), the FHWA Roadway Construction Noise Model (RCNM) was used to predict construction noise at the nearest off-site receptors. RCNM is a computer program used to assess construction noise impacts and allows for user- defined construction equipment and user-defined noise limit criteria. Noise levels were calculated for each construction phase and are based on the equipment used, distance to the nearest property/receptor, and acoustical use factor for equipment.

Following FTA methodology, when calculating construction noise, all equipment is assumed to operate at the center of the active construction zone because equipment would operate throughout the Project site and not at a fixed location for extended periods of time. Therefore, the distances used in the RCNM model were approximately 170 feet to the nearest residential receptor property line to the west, and 100 feet to the nearest commercial property line to the west; refer to Appendix B: Noise Data for RCNM modeling results. Table 10: Project Construction Noise Levels, show estimated exterior construction noise levels at the nearest receptors without accounting for attenuation from physical barriers or topography.

The City of Bellflower does not have construction noise standards. Thus, the FTA’s noise standards of 80 dBA Leq (8-hour) for residential uses and 85 dBA Leq (8-hour) for commercial uses were utilized to analyze the Project’s construction noise impacts. As indicated in Table 10, the highest anticipated construction noise levels of 74.7 dBA at the nearest residential uses, and 79.4 dBA at the nearest commercial uses would not exceed the FTA’s applicable construction noise thresholds. In addition, compliance with the Bellflower Municipal Code and Noise Element would minimize impacts from construction noise, as construction would be limited to the hours of 7:00 a.m. to 6:00 p.m. on weekdays, and 7:00 a.m. to 6:00 p.m. on Saturdays; construction is prohibited on Sundays and City holidays. Therefore, because Project construction noise levels would not exceed FTA noise standards and construction activities would be required to comply with the allowable construction hours in the Bellflower Municipal Code, noise impacts would be less than significant in this regard.

Although construction noise impacts are anticipated to be less than significant, Project construction activities could temporarily increase ambient noise levels in the area and result in a noticeable noise increase at the residential uses immediately to the west. Therefore, it is recommended the Project contractor implement the best management practices set forth in Standard Condition (SC) NOI-1 to minimize potential construction noise conflicts at nearby sensitive uses.

Operations

Implementation of the proposed Project would create new sources of noise in the Project vicinity. The major noise sources associated with the Project that would potentially impact existing nearby residences include stationary noise equipment (i.e., trash compactors, air conditioners, etc.); parking areas (i.e., car door slamming, car radios, engine start-up, and car pass-by); truck deliveries and trash/recycling pickups; drive-thru operations; and off-site traffic noise.

Mechanical Equipment. The nearest sensitive receptors to the Project site are the residences adjoining the Project site to the west. Potential stationary noise sources related to long-term operation of the Project would include mechanical equipment. Mechanical equipment (e.g., heating ventilation and air conditioning [HVAC] equipment) typically generates noise levels of approximately 52 dBA at 50 feet.2 According to Project site plans, the nearest potential location for a HVAC unit would be located approximately 70 feet from the nearest residential property. Based upon the Inverse Square Law, sound levels decrease by 6 dBA for each doubling of distance from the source. As a result, HVAC noise levels would attenuate by the distance to approximately 49.1 dBA, which is well below the City’s 65 dBA CNEL noise standard for residential uses. Operation of mechanical equipment would not increase ambient noise levels beyond the acceptable compatible land use noise levels. Therefore, the proposed Project would result in a less than significant impact related to mechanical equipment noise levels.

Parking Noise. The Project would provide 132 parking stalls, located throughout the Project site. Traffic associated with parking lots is typically not of sufficient volume to exceed community noise standards, which are based on a time-averaged scale such as the CNEL scale. The instantaneous maximum sound levels generated by a car door slamming, engine starting up, and car pass-bys range from 53 to 61 dBA.3 Conversations in parking areas may also be an annoyance to adjacent sensitive receptors. Sound levels of speech typically range from 33 dBA at 50 feet for normal speech to 50 dBA at 50 feet for very loud speech.4 It should be noted that parking lot noises are instantaneous noise levels compared to noise standards in the hourly Leq or 24-hour CNEL metrics, which are averaged over the entire duration of a time period. As a result, actual noise levels over time resulting from parking lot activities would be far lower than the reference levels identified above.

For the purpose of providing a conservative, quantitative estimate of the noise levels that would be generated from the vehicles entering and exiting the parking lot, the methodology recommended by FTA for the general assessment of stationary transit noise sources is used. Using the methodology, the Project’s peak hourly noise level that would be generated by the on-site parking levels was estimated using the following FTA equation for a parking lot:

Leq(h) = SELref + 10 log (NA/1,000) – 35.6
Where:

Leq(h) = hourly Leq noise level at 50 feet
SELref = reference noise level for stationary noise source represented in sound exposure level (SEL) at 50 feet
NA = number of automobiles per hour

35.6 is a constant in the formula, calculated as 10 times the logarithm of the number of seconds in an hour

Based on the peak hour trip generation rates in the Traffic Impact Analysis, approximately 413 trips during peak hours would be made to the Project site each day. Using the FTA’s reference noise level of 92 dBA SEL5 at 50 feet from the noise source, the Project’s highest peak hour vehicle trips would generate noise levels of approximately 52.0 dBA Leq at 50 feet from the parking lot. The nearest sensitive receptors (residential use to the west) would be located approximately 30 feet from the nearest parking lot on the Project site. Based strictly on distance attenuation, parking lot noise at the nearest sensitive receptor (residential uses to the west) would be approximately 56.4 dBA which is below the City’s 65 dBA CNEL residential noise standard. Therefore, noise impacts from parking lots would be less than significant.

Truck Deliveries and Trash/Recycling Collection

The proposed Project would involve occasional deliveries and weekly trash/recycling collection from slow- moving trucks during normal daytime hours. Low speed truck noise results from a combination of engine, exhaust, and tire noise as well as the intermittent sounds of back-up alarms and releases of compressed air associated with truck air-brakes. Medium-sized delivery trucks and trash collection trucks typically

generate noise levels of 75 dBA at distance of 50 feet.6 The nearest noise-sensitive receptors (residential uses to the west of the Project site) would be located approximately 40 feet west of the trash/recycling area in the northwestern portion of the Project site. At this distance and accounting for existing/intervening perimeter walls, noise levels from truck deliveries and trash/recycling collection trucks would be approximately 71.9 dBA.7 It is noted, however, that noise events from trash/recycling truck pickups and truck deliveries would be infrequent and instantaneous, and therefore, would result in much lower noise levels when averaged over a 24-hour time period (i.e., the CNEL scale, which the City utilizes for their noise standards). Therefore, noise levels from truck deliveries and trash/recycling collection are not expected to exceed the City’s 65 dBA CNEL residential noise standard during operations.

A less than significant impact would occur in this regard.

Drive-Thru Operations. Drive-thru operations at the three proposed restaurants on-site would include several noise sources, including amplified speech from the intercoms, idling vehicles, and vehicles circulating along the drive-thru lanes. The measured noise level associated with active drive-thru operations is 64 dBA at a distance of 20 feet.8 The residential properties to the west would be located as close as approximately 150 feet from the nearest menu board/intercom and drive-thru lane/queuing area.

At this distance, drive-thru operational noise levels would be approximately 46.5 dBA and would not exceed the City’s 65 dBA CNEL residential noise standard. As such, noise impacts from drive-thru operations at the Project site would be less than significant.

Combined Noise Levels. Conservatively assuming a worst-case scenario where all noise sources identified above are simultaneously and continuously generating noise (except for truck delivery and trash/recycling collection activities, which would be sporadic and short in duration), the composite noise level at the nearest residential uses to the west would be approximately 57.5 dBA9 and would not exceed the City’s 65 dBA CNEL residential noise standard. In addition, the Project’s operational noise level of 57.5 dBA would not exceed the measured ambient noise level of 59.5 dBA at the residential uses to the west; see Table 7. Therefore, noise levels from on-site Project operations would be less than significant.

Off-Site Traffic Noise. Implementation of the Project would generate increased traffic volumes along nearby roadway segments. According to the Traffic Impact Analysis, the proposed Project would generate 2,815 daily trips which would result in noise increases on Project area roadways. In general, a traffic noise increase of less than 3 dBA is barely perceptible to people, while a 5-dBA increase is readily noticeable.10 Generally, traffic volumes on Project area roadways would have to approximately double for the resulting traffic noise levels to increase by 3 dBA. Therefore, permanent increases in ambient noise levels of less than 3 dBA are considered to be less than significant.

Traffic noise levels for roadways primarily affected by the Project were calculated using the FHWA’s Highway Noise Prediction Model (FHWA-RD-77-108). Traffic noise modeling was conducted for conditions with and without the Project, based on traffic volumes from the Traffic Impact Analysis.

traffic-generated noise levels on Project area roadways would range between 67.9 dBA CNEL and 69.1 dBA CNEL at 100 feet from the centerline, and the Project would result in a maximum increase of 1.3 dBA CNEL along Artesia Boulevard. As the Project would not result in a noticeable increase in traffic noise levels (i.e., an increase of 3 dBA or more) a less than significant would occur in this regard.

 Prior to issuance of any Grading or Building Permit, the Project Applicant shall demonstrate to the satisfaction of the City Engineer that construction noise reduction methods shall be used where feasible. These reduction methods include shutting off idling equipment, maximizing the distance between construction equipment staging areas and occupied residential areas, and electric air compressors and similar power tools.

 Construction haul routes shall be designed to avoid noise-sensitive uses (e.g., residences, convalescent homes, etc.) to the extent feasible.

 During construction, stationary construction equipment shall be placed such that emitted noise is directed away from sensitive noise receivers.

 Project construction activities that generate noise shall be limited to the hours between 7:00 a.m. and 6:00 p.m. Monday through Friday, 8:00 a.m. and 6:00 p.m. on Saturdays, and shall be prohibited on Sundays and City holidays.

Mitigation Measures: No mitigation is required.

Level of Significance: Less than significant impact.

Threshold 6.2 Would the Project generate excessive groundborne vibration or groundborne noise levels?

Increases in groundborne vibration levels attributable to the proposed Project would be primarily associated with short-term construction-related activities. The Federal Transit Administration (FTA) has published standard vibration velocities for construction equipment operations in their 2018 Transit Noise and Vibration Impact Assessment Manual. The types of construction vibration impacts include human annoyance and building damage.

The Federal Transit Administration (FTA) has published standard vibration velocities for construction equipment operations. In general, the FTA architectural damage criterion for continuous vibrations (i.e.,

0.2 in/sec) appears to be conservative. The types of construction vibration impacts include human annoyance and building damage. Human annoyance occurs when construction vibration rises significantly above the threshold of human perception for extended periods of time. Building damage can be cosmetic or structural. Ordinary buildings that are not particularly fragile would not experience any cosmetic damage (e.g., plaster cracks) at distances beyond 30 feet. This distance can vary substantially depending on the soil composition and underground geological layer between vibration source and receiver. In addition, not all buildings respond similarly to vibration generated by construction equipment. For example, for a building that is constructed with reinforced concrete with no plaster, the FTA guidelines show that a vibration level of up to 0.20 in/sec is considered safe and would not result in any construction vibration damage.

Table 12: Typical Construction Equipment Vibration Levels, lists vibration levels at 25 feet for typical construction equipment. Ground-borne vibration generated by construction equipment spreads through the ground and diminishes in magnitude with increases in distance. As indicated in Table 12, based on FTA data, vibration velocities from typical heavy construction equipment operations that would be used during Project construction range from 0.003 to 0.089 in/sec PPV at 25 feet from the source of activity.

Small Bulldozer/Tractors 0.003
Notes:

1. Calculated using the following formula: PPVequip = PPVref x (25/D)1.5, where: PPVequip = the peak particle velocity in in/sec of the equipment adjusted for the distance; PPVref = the reference vibration level in in/sec from Table 7-4 of the Federal Transit Administration, Transit Noise and Vibration Impact Assessment Manual, 2018; D = the distance from the equipment to the receiver.

Source: Federal Transit Administration, Transit Noise and Vibration Impact Assessment Manual, 2018.

The nearest off-site structures (a residence and an auto repair shop building) would be located as close as approximately 25 feet west of the active construction zone. As shown in Table 12, at 25 feet the vibration velocities from construction equipment would not exceed 0.089 in/sec PPV, which is below the FTA’s 0.20 in/sec PPV threshold for building damage and Caltrans’ 0.4 in/sec PPV threshold for human annoyance. It is also acknowledged that construction activities would occur throughout the Project site and would not be concentrated at the point closest to the nearest structure. Therefore, vibration impacts associated with the proposed Project would be less than significant.

Once operational, the Project would not be a significant source of groundborne vibration. Groundborne vibration surrounding the Project currently result from heavy-duty vehicular travel (e.g., trash/recycling trucks, heavy duty trucks, and delivery trucks, etc.) on the nearby local roadways. Due to the rapid drop- off rate of ground-borne vibration and the short duration of the associated events, vehicular traffic- induced ground-borne vibration is rarely perceptible beyond the roadway right-of-way, and rarely results in vibration levels that cause damage to buildings in the vicinity. Impacts would be less than significant in this regard.

Mitigation Measures: No mitigation is required.

Level of Significance: Less than significant impact.

Threshold 6.3 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?

The nearest airport to the Project site is the Long Beach Airport located approximately 3.35 miles to the southwest. The Project is not within 2.0 miles of a public airport or within an airport land use plan.

Additionally, there are no private airstrips located within the Project vicinity. Therefore, the Project would not expose people residing or working in the Project area to excessive airport- or airstrip-related noise levels and no mitigation is required.

Mitigation Measures: No mitigation is required.

Level of Significance: Less than significant impact.

6.2 Cumulative Noise Impacts

Cumulative Construction Noise

The Project’s construction activities would not result in a substantial temporary increase in ambient noise levels. Construction noise would be periodic and temporary noise impacts that would cease upon completion of construction activities. The Project would contribute to other proximate construction project noise impacts if construction activities were conducted concurrently. However, based on the noise analysis above, the Project’s construction-related noise impacts would be less than significant following the Bellflower Municipal Code and Noise Element and would implement SC NOI-1 to minimize construction noise levels at nearby sensitive uses.

Construction activities at other planned and approved projects near the Project site would be required to comply with applicable City rules related to noise and would take place during daytime hours on the days permitted by the applicable Municipal Code, and projects requiring discretionary City approvals would be required to evaluate construction noise impacts, comply with the City’s standard conditions of approval, and implement mitigation, if necessary, to minimize noise impacts. Construction noise impacts are by nature localized. Based on the fact that noise dissipates as it travels away from its source, noise impacts would be limited to the Project site and vicinity. Therefore, Project construction would not result in a cumulatively considerable contribution to significant cumulative impacts, assuming such a cumulative impact existed, and impacts in this regard are not cumulatively considerable.

Cumulative Operational Noise

Cumulative Off-Site Traffic Noise

Cumulative noise impacts describe how much noise levels are projected to increase over existing conditions with the development of the proposed Project and other foreseeable projects. Cumulative noise impacts would occur primarily as a result of increased traffic on local roadways due to buildout of the proposed Project and other projects in the vicinity. Cumulative increases in traffic noise levels were estimated by comparing the Existing and Opening Year Without Project scenarios to the Opening Year Plus Project scenario. The traffic analysis considers cumulative traffic from future growth assumed in the transportation model, as well as cumulative projects.

A project’s contribution to a cumulative traffic noise increase would be considered significant when the combined effect exceeds perception level (i.e., auditory level increase) threshold. The following criteria is used to evaluate the combined and incremental effects of the cumulative noise increase.

 Combined Effect. The cumulative with Project noise level (“Opening Year With Project”) would cause a significant cumulative impact if a 3.0 dB increase over “Existing” conditions occurs and the resulting noise level exceeds the applicable exterior standard at a sensitive use. Although there may be a significant noise increase due to the proposed Project in combination with other related projects (combined effects), it must also be demonstrated that the Project has an incremental effect. In other words, a significant portion of the noise increase must be due to the proposed Project.
 Incremental Effects. The “Opening Year With Project” causes a 1.0 dBA increase in noise over the “Opening Year Without Project” noise level.

City of Bellflower Bellflower Convenience Center
Acoustical Assessment
June 2022
Page | 30
A significant impact would result only if both the combined and incremental effects criteria have been exceeded. Noise by definition is a localized phenomenon and reduces as distance from the source increases. Consequently, only the proposed Project and growth due to occur in the general area would contribute to cumulative noise impacts.

Table 13: Cumulative Traffic Noise Levels identifies the traffic noise effects along roadway segments in the Project vicinity for “Existing,” “Opening Year Without Project,” and “Opening Year With Project,” conditions, including incremental and net cumulative impacts. Table 13 shows the increase for combined effects and incremental effects and none of the segments meet the criteria for cumulative noise increase.

The proposed Project would not result in long-term mobile noise impacts based on project-generated traffic as well as cumulative and incremental noise levels. Therefore, the proposed Project, in combination with cumulative background traffic noise levels, would result in a less than significant cumulative impact.

The proposed Project’s contribution would not be cumulatively considerable.

Refer to Appendix B for traffic noise modeling results.

Cumulative Stationary Noise

Stationary noise sources of the proposed Project would result in an incremental increase in non- transportation noise sources in the Project vicinity. However, as discussed above, operational noise caused by the proposed Project would be less than significant. Similar to the proposed Project, other planned and approved projects would be required to mitigate for stationary noise impacts at nearby sensitive receptors, if necessary. As stationary noise sources are generally localized, there is a limited potential for other projects to contribute to cumulative noise impacts.

No known past, present, or reasonably foreseeable projects would combine with the operational noise levels generated by the Project to increase noise levels above acceptable standards because each project must comply with applicable City regulations that limit operational noise. Therefore, the Project, together with other projects, would not create a significant cumulative impact, and even if there was such a significant cumulative impact, the Project would not make a cumulatively considerable contribution to significant cumulative operational noises.

Given that noise dissipates as it travels away from its source, operational noise impacts from on-site activities and other stationary sources would be limited to the Project site and vicinity. Thus, cumulative operational noise impacts from related projects, in conjunction with Project specific noise impacts, would not be cumulatively significant.

Mitigation Measures: No mitigation is required.

Level of Significance: Less than significant impact.

Low Impact
Development (LID) Report

1. Introduction

1.1 Project Description and Purpose
The Bellflower Convenience Center (Project) is located at 17617, 17625, and 17639 Bellflower Blvd, Bellflower, CA 90706. The Project is located in the County of Los Angeles and is located approximately 1.1 miles West of the San Gabriel River.

The Project consists of the redevelopment of the entire Bellflower Convenience Center lot. The project area includes the following improvements: new building pads, associated parking, and proposed landscape shown in Appendix A. Redevelopment will also incorporate drainage features and stormwater BMPs.

Kimley-Horn is contracted to produce construction documents for the redevelopment. This report summarizes the Low Impact Development (LID) analyses related to the project.

2. Low Impact Development

2.1 Designated Project Classification
The project encompasses approximately 158,192 (3.63 ac) and previously consisted of multiple vacant buildings and surrounding parking areas. The project is considered a Designated Project because it is a

five

Low Impact
Development (LID) Report
redevelopment project that results in creation or addition or replacement of 5,000 square feet or more of impervious surface.

This project is required to adhere to all requirements set forth in the current MS4 permit and General Construction Permit.

2.2 Stormwater Management Requirements for Designated Projects All Designated Projects must retain 100 percent of the Stormwater Quality Design Volume (SWQDv) on-site through infiltration, evapotranspiration, stormwater runoff harvest and use, or a combination thereof unless it demonstrated that is technically infeasible to do so. The Project will implement detention and drywell systems to treat the SWQDv.

2.3 Watershed-Based Plan Conditions
Under existing conditions, stormwater runoff within the project generally sheet flows in the southeasterly and northeasterly directions and sheet flows towards Ramona St. and Cedar St., where the water travels through gutters and eventually trapped by curb opening catch basins. The LA County owned storm drain system discharges to San Gabriel River Reach 2. The San Gabriel River Reach 2 eventually enters the San Gabriel River Reach 1 and ultimately the San Pedro Bay Near/Off Shore Zones. There are no hydromodification requirements because the project area does not discharge to a natural drainage system. The receiving waterbody and downstream waterbodies have the following impairments per the 2016 California Clean Water Act Section 303(d) list.  San Gabriel River Reach 2: Copper, Cyanide, Indicator Bacteria, Water Temperature, Zinc  San Gabriel River Reach 1: Abnormal Fish Histology, Excess Algal Growth, Indicator Bacteria, pH, Water Temperature, Toxicity
 San Pedro Bay Near/Off Shore Zones: chlordane, Polychlorinated byphenyls (PBCs), total DDT, and toxicity.

2.4 Potential Stormwater Pollutants
Pollutants of concern potentially generated by the project include suspended solid/sediment; nutrients; metal; and trash and debris. Priority pollutants of concern include nutrients, and trash. BMPs as described in Sections 3 and 4 will be used to minimize and prevent these pollutants in the stormwater runoff from the project site.

2.5 Feasibility of Infiltration
Per the Geotechnical Exploration Report dated April 19, 2021, completed by Krazan & Associates, Inc., field infiltration tests found unfactored infiltration rates of 51 inches per hour at depths 8 ft below ground surface (bgs).

A factor of Safety of 12 has been applied to the unfactored infiltration rate per the Geotechnical Report. The final design infiltration rate of 4.25 inches per hour will be used for the design of the proposed infiltration BMPs. Per the Geotechnical Report, the bottom of the infiltration BMP will be at 10 ft bgs. A copy of the Geotechnical Exploration Report is included in Appendix G.

Groundwater was not encountered during the geotechnical investigation. Per the geotechnical engineer, based on modern historical data, minimum groundwater depths of approximately 50 feet bgs are expected in this area. The infiltration BMP will be 10 feet above the historical groundwater depth.

Infiltration BMPs will be located on the south side of the project. These BMPs do not pose risk of pollutant mobilization, have sufficient set back from existing structures or foundations, would not damage existing utilities, and are further than 100 feet away from any groundwater production wells. There are no Significant Ecological Areas (SEAs) within the vicinity of the project site.

2.6 Site Design Principles
Low Impact
Development (LID) Report
There is no existing storm water management on site. Proposed conditions are to capture and treat all storm water on site. In addition, overall impervious areas were reduced from a 96.8% impervious site to 86.9% imperviousness.

2.7 Source Control BMPs
Source control BMPs include permanent, structural features, such as roofs over and berms around trash and recycling areas, and Operational BMPs, such as regular sweeping and “housekeeping”, that must be implemented by the site’s occupant or user. Per Table 5-1 (Source Control Measures Selections Matrix) of the LID Manual, the following source control measures should be implemented due to the proposed uses at the site:
 Storm Drain Message and Signage (S-1) – Signs with language and/or graphical icons that prohibit illegal dumping, must be posted at catch basins within project area.  Landscape Irrigation Practices (S-8) – Apply efficient irrigations practices by not allowing irrigation runoff from landscaped areas to drain directly to storm drain system; minimize use of fertilizer, pesticides, and herbicides on landscaped areas, and plan sites with sufficient landscape area and dispersal capacity.  Building Materials (S-9) – Building materials can potentially contribute pollutants of concern to stormwater runoff through leaching. The use of alternative building materials can reduce pollutant sources in stormwater runoff by eliminating compounds that can leach into stormwater runoff.

2.8 Stormwater Quality Volume Calculation
The SWQDv was calculated in accordance with the Los Angeles County Department of Public Works Low Impact Development Standards Manual (LACDPW, 2014). Per the manual, the design storm from which the SWQDv is calculated is defined as the greater of:
 The 0.75-inch, 24-hour rain event; or
 The 85th percentile, 24-hr rain event as determined from the Los Angeles County 85 th percentile precipitation isohyetal map.

The 85th percentile, 24-hr rain event for the project site was approximately 0.90 inches and was selected as the SWQDv design storm for the LID design. The project site has type 6 soils based on Los Angeles County GIS Hydrology Map. The Los Angeles County HydroCalc hydrologic calculator was used to complete the Modified Rational Method calculation process to determine the SWQDv. Table 1 shows the HydroCalc results for the 85 th percentile storm for the Project limits.

3. Best Management Practices (BMPs)
Low Impact
Development (LID) Report

LID calculations were performed to determine the effects of the proposed construction on the existing site. The feasibility calculations have been performed based on the County of Los Angeles, Low Impact Development Standards Manual (LACDPW, 2014). The layout of the proposed BMP’s can be seen in the preliminary drainage plan in Appendix A.

Infiltration based BMPs are proposed to treat the SWQDv. An infiltration system, Torrent Maxwell Plus underground dry well and settling chamber, have been selected to treat the stormwater volume from the Project limits. Due to the limited volume in the drywells, a detention system is required prior to treatment. Detention volume has been sized, is included in the calculations, and shown on plans in Appendix A The maximum infiltration depth was calculated using the design infiltration rate of 4.25 inches per hour and the equation below.

Refer to Appendix D for full BMP calculations and manufacturer’s system design output.

𝑀𝑎𝑥 𝑑𝑒𝑝𝑡ℎ = 𝑡𝑝(𝑓𝑑)
12 (Eq. 1)
Where, tp = Drawdown time, max 96 hours (hr)
fd = Design infiltration rate (in/hr)

3.1 Structural BMPs
Design treatment flow from the Project will enter the detention system, Contech Cistern, via a proposed underground storm drain system. Flow will then travel through to the infiltration system, Torrent Maxwell Plus underground dry well and settling chamber. The infiltration system locations are indicated in the drainage plan in Appendix A. LID calculations and sizing for the system have been included in Appendix D.

Torrent Maxwell Plus underground dry well and settling chamber will also provide pretreatment for suspended solids. The system has an additional pretreatment chamber to protect the drywell side from any sediment or debris.

Refer to the infiltration system detail in Appendix E.

4. Overflow Storm Calculations
The Project consists of five major drainage areas that will be treated by three dry-well systems. Discharge from the Site Parking drainage area will enter a diversion structure that will allow the 85-percentile flow for the Project limits to enter the infiltration system via an 8-inch storm drain. Runoff exceeding the 85-percentile storm event will stage up in the diversion structure and discharge via curb drains to Bellflower Street and Ramona St.

5. BMP and Drainage Structures Maintenance

5.1 Property Ownership/Management
The BMPs will be inspected and maintained by the property owner.

5.2 Shared Structural BMPs
This project is designed to include shared underground storm systems between multiple tenants. Pad 1 and Pad 2 will share underground storm detention and dry-well infiltration ‘DW-1’. Pad 3 and 4 will share ‘DW-2’. Pad 5 will not share an underground system with any other tenants outside of Pad 5 and will have its own system identified as ‘DW-3’. It shall be recorded in the Project’s CC&Rs that the maintenance of each underground storm system will be at the shared cost of the tenant(s) who’s drainage runoff enters the system. A Property Management group shall be identified in the CC&Rs to manage and hold the tenant(s) responsible for future cost(s) of the system, including but not limited to maintenance.

4 | P a g e
.

5.3 BMP Maintenance and Operations Plan
The BMP’s set forth in this report will be funded, implemented, and maintained by the property owner. Fair share operation and maintenance costs are to be shared between the tenants, and responsibilities outlined in the Covenants, Codes, and Restrictions (CC&Rs) recorded to the property. If a new tenant is to come into the space, the BMPs are to remain in place. In general, all BMP’s should be inspected before and after the rainy season as well as during regular maintenance of the storm drain catch basins. A maintenance schedule will be established and retained for records.
