EXECUTIVE SUMMARY

The 6.94-acre project site is located east of Commerce Street between 5th Street and Mission Inn Avenue in the City of Riverside, California. The project site is currently partially developed with commercial/industrial buildings and zoned as Business & Manufacturing Park Zone (BMP).

The proposed project (TTM 38624) involves removal of the existing buildings and construction of 295 mid- rise multifamily dwelling units and 5 low-rise multifamily dwelling units within a residential complex. Vehicular access for the project site is proposed via two driveways with one on 5th Street and one on Mission Inn Avenue.

The project site requires a General Plan Amendment and Zoning Amendment to rezone the site from Business & Manufacturing Park Zone (BMP) to Mixed-use Urban (MU-U) to accommodate the residential development and a Specific Plan Amendment to amend the Riverside Marketplace Specific Plan to expand the mixed-used Marketplace Sub-area. The proposed plan also includes a street vacation of 6th Street from Commerce Street to the east side of the project.

Existing Noise Environment

Sensitive receptors that may be affected by project generated noise include the existing single-family residential uses located adjacent to the east, approximately 100 feet southeast (across Mission Inn Avenue), and approximately 65 feet northeast (across 5 th Street) and the multi-family residential uses located approximately 100 feet south (across Mission Inn Avenue) of the project site. In addition, North Park is located approximately 361 feet southwest of the project site.

Measured short-term ambient noise levels in the project vicinity ranged between 56.7 and 71.7 dBA Leq. Long- term hourly noise measurement ambient noise levels ranged from 53.5 to 75.6 dBA L eq. The dominant noise source in the project vicinity was vehicle traffic associated with Mission Inn Avenue, 91 Freeway, Commerce Street, and other surrounding roadways as well as train activity (i.e., moving trains, horns, and crossing bells).

Project Construction Impacts – Onsite Equipment

The City of Riverside’s General Plan and Municipal Code do not establish numeric maximum acceptable construction source noise levels for potentially affected receivers. Per the Federal Transit Administration (FTA), daytime construction noise levels should not exceed 80 dBA Leq for an 8-hour period at residential uses and 85 dBA L eq for an 8-hour period at commercial uses. Based on the modeled construction noise levels, construction noise levels are estimated to reach up to 75.29 dBA L eq at the nearest residential property line anx 72.3 dBA L eq at the nearest commercial property line. Furthermore, project construction will not occur outside of the hours outlined in City of Riverside Municipal Code Section 7.35.020(G). Therefore, the project would not exceed established standards relating to construction noise. Project construction would not be anticipated to exceed the FTA thresholds for either residential or commercial uses. The project impact is less than significant; no mitigation is required.

Notwithstanding the above, recommended best management practices (BMPs) are provided in the Project Description which can be added to project plans and in contract specifications to minimize construction noise emanating from the proposed project.

Project Construction Impacts – Offsite Vehicle Trips

Project vehicle traffic generated during project construction would be anticipated to be nominal relative to existing roadway volumes and would not result in the doubling of traffic volume necessary to increase noise levels by 3 dBA. The project impact is less than significant; no mitigation is required.

Operational Noise Impacts – Offsite Vehicle Trips
The addition of project trips is not expected to change noise levels more than the applicable threshold at any of the study roadway segments. The project impact is less than significant; no mitigation is required.

Operational Noise Impacts –Traffic to Project

Transportation related noise is expected to range between 61 and 72 dBA CNEL. Development of infill residential land uses are considered to be “normally acceptable” in areas where noise levels reach up to 65 dBA CNEL. With implementation of the following mitigation measures.

Mitigation Measure 1
Windows and glass doors shall have STC ratings as presented in Table 13. Where no STC is listed, standard windows that meet California Building Code requirements will suffice.

Groundborne Vibration Impacts

Potential for Damage

Groundborne vibration generated by project construction would exceed the levels necessary to cause architectural damage at the residential structures to the east (along 5 th Street and 6 th Street) of the project site. The following measure is recommended to ensure groundborne vibration generated by project construction does not cause architectural damage to nearby buildings:

Mitigation Measure 2
Use of vibratory rollers, or other similar vibratory equipment, within 26 feet of structures surrounding the project site shall be prohibited.

With implementation of Mitigation Measure 1, groundborne vibration generated by project construction would not exceed the levels necessary to cause architectural damage; therefore, the project impact would be less than significant.

Potential for Annoyance

Furthermore, the threshold for annoyance due to vibration (80 VdB at offsite sensitive uses) could be exceeded at the existing residential land uses surrounding the project site and residents may be temporarily annoyed. However, the impact would only occur when construction equipment is operating within 74 feet of the residential structures and only during daytime hours and will be temporary.

Operational Groundborne Vibration

The most substantial sources of groundborne vibration during post-construction project operations will include the movement of passenger vehicles and trucks on paved and generally smooth surfaces. Loaded trucks generally have a PPV of 0.076 at a distance of 25 feet (Caltrans 2020), which is a substantially lower PPV than that of a vibratory roller (0.210 in/sec PPV at 25 feet). Therefore, groundborne vibration levels generated by project operation would not exceed those modeled for project construction. This impact would not be significant. No mitigation is required.

Rail Groundborne Vibration

The proposed project site is located approximately 170 feet southeast of the BNSF rail line. The closest proposed building is approximately 12 feet from the property line. Groundborne vibration generated by project construction would reach up to 53 VdB at the nearest proposed structure and would not exceed any Iron Lofts Multifamily Residential
Noise Impact Analysis
v 19630
of the thresholds for potential damage or annoyance. Impacts would be less than significant; no mitigation is required.

Air Traffic Impacts

The project site is located well outside the 55 dBA CNEL noise contours of the Flabob and Riverside Municipal Airports. Therefore, the project would not expose people residing or working in the project area to excessive noise levels associated with airports. The impact would be less than significant; no mitigation is required.

1. INTRODUCTION

This section describes the purpose of this study and the proposed project.

PURPOSE AND OBJECTIVES

The purpose of this report is to provide an assessment of the noise impacts resulting from development and operation of the proposed project and to identify mitigation measures that may be necessary to reduce potentially significant impacts. The noise issues related to the proposed land use and development have been evaluated in light of applicable federal, state and local policies, including those of the City of Riverside, in the context of the California Environmental Quality Act (CEQA).

Although this is a technical report, effort has been made to write the report clearly and concisely. A list of acronyms and glossary are provided in Appendix A and Appendix B of this report to assist the reader with technical terms related to noise and vibration analysis.

PROJECT LOCATION

PROJECT DESCRIPTION

Although project construction noise impacts would not exceed applicable thresholds, the following best management practices (BMPs) can be provided on project plans and in contract specifications to minimize construction noise emanating from the proposed project:

1. All equipment, whether fixed or mobile, will be equipped with properly operating and maintained mufflers, consistent with manufacturer standards.

2. All stationary construction equipment will be placed so that emitted noise is directed away from the noise sensitive receptors nearest the project site.

3. As applicable, all equipment shall be shut off and not left to idle when not in use.

4. To the degree possible, equipment staging will be located in areas that create the greatest distance between construction-related noise and vibration sources and existing sensitive receptors.

5. Portable stationary noise sources will be directed away and shielded from existing residences in the vicinity of the project site. Either one-inch plywood or sound blankets can be utilized for this purpose.

They should reach up from the ground and block the line of sight between equipment and existing residences. The shielding should be without holes and cracks. 1 Iron Lofts Multifamily Residential

2. NOISE AND VIBRATION FUNDAMENTALS

This section provides an overview of key noise and vibration concepts.

NOISE FUNDAMENTALS

Sound is a pressure wave created by a moving or vibrating source that travels through an elastic medium such as air. Noise is defined as unwanted or objectionable sound. The effects of noise on people can include general annoyance, interference with speech communication, sleep disturbance, and in extreme circumstances, hearing impairment.

Commonly used noise terms are presented in Appendix B. The unit of measurement used to describe a noise level is the decibel (dB). The human ear is not equally sensitive to all frequencies within the sound spectrum.

Therefore, the “A-weighted” noise scale, which weights the frequencies to which humans are sensitive, is used for measurements. Noise levels using A-weighted measurements are written dB(A) or dBA.

From the noise source to the receiver, noise changes both in level and frequency spectrum. The most obvious is the decrease in noise as the distance from the source increases. The manner in which noise reduces with distance depends on whether the source is a point or line source as well as ground absorption, atmospheric effects and refraction, and shielding by natural and manmade features. Sound from point sources, such as air conditioning condensers, radiates uniformly outward as it travels away from the source in a spherical pattern.

The noise drop-off rate associated with this geometric spreading is 6 dBA per each doubling of the distance (dBA/DD). Transportation noise sources such as roadways are typically analyzed as line sources, since at any given moment the receiver may be impacted by noise from multiple vehicles at various locations along the roadway. Because of the geometry of a line source, the noise drop-off rate associated with the geometric spreading of a line source is 3 dBA/DD.

Decibels are measured on a logarithmic scale, which quantifies sound intensity in a manner similar to the Richter scale used for earthquake magnitudes. Thus, a doubling of the energy of a noise source, such as a doubled traffic volume, would increase the noise levels by 3 dBA; halving of the energy would result in a 3 dBA decrease. Figure 3 shows the relationship of various noise levels to commonly experienced noise events.

Average noise levels over a period of minutes or hours are usually expressed as dBA L eq, or the equivalent noise level for that period of time. For example, Leq(3-hr) would represent a 3-hour average. When no period is specified, a one-hour average is assumed.

Noise standards for land use compatibility are stated in terms of the Community Noise Equivalent Level (CNEL) and the Day-Night Average Noise Level (DNL). CNEL is a 24-hour weighted average measure of community noise. CNEL is obtained by adding five decibels to sound levels in the evening (7:00 PM to 10:00 PM), and by adding ten decibels to sound levels at night (10:00 PM to 7:00 AM). This weighting accounts for the increased human sensitivity to noise during the evening and nighttime hours. DNL is a very similar 24- hour average measure that weights only the nighttime hours.

It is widely accepted that the average healthy ear can barely perceive changes of 3 dBA; that a change of 5 dBA is readily perceptible, and that an increase (decrease) of 10 dBA sounds twice (half) as loud. This definition is recommended by the California Department of Transportation’s Technical Noise Supplement to the Traffic Noise Analysis Protocol (2013).

VIBRATION FUNDAMENTALS

The way in which vibration is transmitted through the earth is called propagation. Propagation of earthborn vibrations is complicated and difficult to predict because of the endless variations in the soil through which waves travel. There are three main types of vibration propagation: surface, compression and shear waves. 5 Iron Lofts Multifamily Residential
Noise Impact Analysis
6 19630
Surface waves, or Rayleigh waves, travel along the ground’s surface. These waves carry most of their energy along an expanding circular wave front, similar to ripples produced by throwing a rock into a pool of water.

Compression waves, or P-waves, are body waves that carry their energy along an expanding spherical wave front. The particle motion in these waves is longitudinal (i.e., in a “push-pull” fashion). P-waves are analogous to airborne sound waves. Shear waves, or S-waves, are also body waves that carry energy along an expanding spherical wave front. However, unlike P-waves, the particle motion is transverse or “side-to-side and perpendicular to the direction of propagation”.

As vibration waves propagate from a source, the energy is spread over an ever-increasing area such that the energy level striking a given point is reduced with the distance from the energy source. This geometric spreading loss is inversely proportional to the square of the distance. Wave energy is also reduced with distance as a result of material damping in the form of internal friction, soil layering, and void spaces. The amount of attenuation provided by material damping varies with soil type and condition as well as the frequency of the wave.

Vibration amplitudes are usually expressed as either peak particle velocity (PPV) or the root mean square (RMS) velocity. The PPV is defined as the maximum instantaneous peak of the vibration signal in inches per second. The RMS of a signal is the average of the squared amplitude of the signal in vibration decibels (VdB), ref one micro-inch per second. The Federal Railroad Administration uses the abbreviation “VdB” for vibration decibels to reduce the potential for confusion with sound decibel.

PPV is appropriate for evaluating the potential of building damage and VdB is commonly used to evaluate human response. Decibel notation acts to compress the range of numbers required in measuring vibration.

Similar to the noise descriptors, L eq and Lmax can be used to describe the average vibration and the maximum vibration level observed during a single vibration measurement interval. Figure 4 illustrates common vibration sources and the human and structural responses to ground-borne vibration. As shown in the figure, the threshold of perception for human response is approximately 65 VdB; however, human response to vibration is not usually substantial unless the vibration exceeds 70 VdB and then it depends on the frequency of the event. Vibration tolerance limits for sensitive instruments such as magnetic resonance imaging (MRI) or electron microscopes could be much lower than the human vibration perception threshold. 6 Figure 3

3. EXISTING NOISE ENVIRONMENT

This section describes the existing noise setting in the project vicinity.

EXISTING LAND USES AND SENSITIVE RECEPTORS

The project site is bordered by Commerce Street to the west, 5th Street to the north, Mission Inn Avenue to the south, and single-family residential uses to the east of the project site.

The State of California defines sensitive receptors as those land uses that require serenity or are otherwise adversely affected by noise events or conditions. Schools, libraries, churches, hospitals, single and multiple- family residential, including transient lodging, motels and hotel uses make up the majority of these areas.

Existing sensitive land uses that may be affected by project noise include the existing single-family residential uses located adjacent to the east, approximately 100 feet southeast (across Mission Inn Avenue), and approximately 65 feet northeast (across 5th Street) and the multi-family residential uses located approximately 100 feet south (across Mission Inn Avenue) of the project site. In addition, North Park is located approximately 361 feet southwest of the project site.

AMBIENT NOISE MEASUREMENTS

An American National Standards Institute (ANSI Section SI.4 2014, Class 1) Larson Davis model LxT sound level meter was used to document existing ambient noise levels. In order to document existing ambient noise levels in the project area, five (5) 15-minute daytime noise measurements were taken between 1:02 PM and 3:43 PM on June 1, 2023. In addition, one (1) long-term 24-hour noise measurement was also taken from June 1, 2023 to June 2, 2023. Figure 5 shows the noise measurement location map. Field worksheets and noise measurement worksheets are provided in Appendix C.

 STNM1: represents the existing noise environment of the multi-family residential use located to the south of the project site along the southern side of Mission Inn Avenue (Mission Lofts Apartments, 3050 Mission Inn Avenue). The noise meter was placed near the northern property line of the residential use just south of Mission Inn Avenue.
 STNM2: represents the existing noise environment of the single-family residential uses located just east of the project site along 6 th Street (2981 6 th Street). The noise meter was placed just northwest of the residential use and south of 6th Street.
 STNM3: represents the existing noise environment of the single-family residential uses located just northeast of the project site along 5th Street (2980 5th Street). The noise meter was placed just northwest of the residential use and south of 5th Street.
 STNM4: represents the existing noise environment of the single-family residential uses located to the north/northeast of the project site along 4 th Street (3008 4 th Street). The noise meter was placed just northwest of the residential use and south of 4th Street.  STNM5: represents the existing noise environment of the western boundary of the project site. The noise meter was placed just southeast of the intersection of Commerce Street and 6 th Street.  LTNM1: represents the existing noise environment of the project site. The noise meter was placed within the western portion of the project site just south of 6th Street.

Table 1 provides a summary of the short-term ambient noise data. Table 2 provides hourly interval ambient noise data from the long-term noise measurements. Measured short-term ambient noise levels ranged between 56.7 and 71.7 dBA Leq. Long-term hourly noise measurement ambient noise levels ranged from 53.5 to 75.6 dBA Leq. The dominant noise source in the project vicinity was vehicle traffic associated with Mission 9 Iron Lofts Multifamily Residential

Inn Avenue, 91 Freeway, Commerce Street, and other surrounding roadways as well as train activity (i.e., moving trains, horns, and crossing bells). A Burlington Northern Santa Fe (BNSF) rail line runs parallel to the project site approximately 160 feet to the northwest of the project site. While other residential and traffic background noise is readily noticeable during non-train pass-by periods, the passing of trains at this location dominates the noise environment and is the primary contributor to the overall community equivalent noise level (CNEL). According to a United States Department of Crossing Inventory Form for this location (see Appendix D), nine passenger trains and nine freight trains (5 day plus 4 night) for a total of 18 trains per day pass by the project site per day. The trains vary in length but can be very long. Train pass-by events are also evident in the 24-hour hourly noise data collected at LTNM1. During the 24-hour measurement taken approximately 260 feet southeast of the rail line (LTNM1), a total of 45 one-minute measurements were 80 dBA or greater (up to 91.3dBA) were measured.

4. REGULATORY SETTING

This section documents the regulatory framework and applicable noise standards.

FEDERAL REGULATION

Federal Noise Control Act of 1972

The U.S. Environmental Protection Agency (EPA) Office of Noise Abatement and Control was originally established to coordinate federal noise control activities. After its inception, EPA’s Office of Noise Abatement and Control issued the Federal Noise Control Act of 1972, establishing programs and guidelines to identify and address the effects of noise on public health, welfare, and the environment. In response, the EPA published Information on Levels of Environmental Noise Requisite to Protect Public Health and Welfare with an Adequate Margin of Safety (Levels of Environmental Noise). The Levels of Environmental Noise recommended that the Ldn should not exceed 55 dBA outdoors or 45 dBA indoors to prevent significant activity interference and annoyance in noise-sensitive areas.

In 1981, EPA administrators determined that subjective issues such as noise would be better addressed at lower levels of government. Consequently, in 1982 responsibilities for regulating noise control policies were transferred to State and local governments. However, noise control guidelines and regulations contained in EPA rulings in prior years remain in place by designated Federal agencies, allowing more individualized control for specific issues by designated Federal, State, and local government agencies.

Federal Interagency Commission on Noise (FICON)

The Federal Interagency Commission on Noise (FICON) has published thresholds that can be used to assess whether a project may result in a substantial increase in noise levels where a lead agency has not adopted their own, as follows:

 If project generated vehicle traffic results in an increase of 5 dB or more where existing ambient noise levels are less than 60 dB CNEL at existing sensitive noise receptors; or

 If project generated vehicle traffic results in an increase of 3 dB or greater where existing ambient noise levels are 60 to 65 dBA CNEL at existing sensitive noise receptors; or

 If project generated vehicle traffic results in an increase of 1.5 dB or more where existing ambient noise levels are greater than 65 dBA CNEL at existing sensitive noise receptors.

Federal Transit Administration

Transit and Construction Noise

FTA standards and criteria for assessing noise impacts related to transit projects are based on community reactions to noise. The criteria reflect changes in noise exposure using a sliding scale where the higher the level of existing noise, the smaller increase in total noise exposure is allowed. Some land use activities are more sensitive to noise than others, such as parks, churches and residences, as compared to industrial and commercial uses. FTA Noise Impact Criteria groups sensitive land uses into the three categories described below.

(1) Category 1 – High Sensitivity: Land where quiet is an essential element of its intended purpose. Example land uses include preserved land for serenity and quiet, outdoor amphitheaters and concert pavilions, and national historic landmarks with considerable outdoor use. Recording studios and concert halls are also included in this category.
14 Iron Lofts Multifamily Residential
Noise Impact Analysis
15 19630
(2) Category 2 – Residential: This category is applicable all residential land use and buildings where people normally sleep, such as hotels and hospitals.
(3) Category 3 – Institutional: This category is applicable to institutional land uses with primarily daytime and evening use. Example land uses include schools, libraries, theaters, and churches where it is important to avoid interference with such activities as speech, meditation, and concentration on reading material.

Places for meditation or study associated with cemeteries, monuments, museums, campgrounds, and recreational facilities are also included in this category.

Most commercial or industrial uses are not considered noise-sensitive because activities within these buildings are generally compatible with higher noise levels. Business can be considered noise-sensitive if low noise levels are an important part of operations, such as sound and motion picture recording studios. Most parks used primarily for active recreation such as sports complexes and bike or running paths are not considered noise-sensitive. However, some parks (even some in dense urban areas) are primarily used for passive recreation such as reading, conversation, or meditation. These places, which may be valued as havens from the noise and rapid pace of everyday city life, are treated as noise-sensitive, and are included in land use Category 3. Non-sensitive uses do not require noise impact assessment.

Construction noise is assessed using guidance provided in the FTA Guidance Manual. The FTA provides reasonable criteria for assessing construction noise impacts based on the potential for adverse community reaction. For residential uses, the daytime noise threshold is 80 dBA L eq averaged over an 8-hour period (L eq (8-hr); and the nighttime noise threshold is 70 dBA L eq (8-hr). For commercial uses, the daytime and nighttime noise threshold is 85 dBA Leq (8-hr) and for industrial uses the daytime and nighttime noise threshold is 90 dBA Leq (8-hr).

Transit and Construction Vibration

FTA has developed impact criteria for acceptable levels of groundborne noise and groundborne vibration.

Criteria for ground-borne vibration are expressed in terms of rms velocity levels in VdB, and criteria for ground-borne noise are expressed in terms of A-weighted sound pressure levels in dBA. Table 3 shows that 80 VdB is the threshold for annoyance from groundborne vibration at sensitive receptors for infrequent events. The FTA also provides criteria for special buildings such as concert halls, television and recording studios, auditoriums, and theaters, which are also sensitive to vibration but do not fit into the three FTA sensitive land use categories previously described.

Ground-borne noise that accompanies the building vibration is usually perceptible only inside buildings and typically is only an issue at locations with subway or tunnel operations where there is no airborne noise path or for buildings with substantial sound insulation such as a recording studio. 1 As such, available guidelines from the FTA are utilized to assess impacts due to ground-borne vibration. The FTA has adopted vibration standards that are used to evaluate potential building damage impacts related to construction activities. As shown in Table 4, the threshold at which there is a risk to “architectural” damage to non-engineered timber and masonry buildings is a peak particle velocity (PPV) of 0.2 (94 VdB), at engineered concrete and masonry buildings a PPV of 0.3 (98 VdB), and at reinforced-concrete, steel, or timber buildings a PPV of 0.5 (102 VdB).

STATE REGULATIONS

California Code of Regulations

The State of California’s noise insulation standards are codified in the California Code of Regulations, Title 24, Building Standards Administrative Code, Part 2 and the California Building Code. These noise standards are applied to new construction in California for the purpose of controlling interior noise levels resulting from exterior noise sources. The regulations specify that acoustical studies must be prepared when noise-sensitive structures, including residential buildings, are developed near major transportation noise sources, and where

1 Federal Transit Administration, Transit Noise and Vibration Impact Assessment, May 2018, pp 108, 112. 15 Iron Lofts Multifamily Residential
Noise Impact Analysis
16 19630
such noise sources create an exterior noise level of 60 dB CNEL or higher. Acoustical studies that accompany building plans for noise-sensitive land uses must demonstrate that the structure has been designed to limit interior noise in habitable rooms to acceptable noise levels. For new residential buildings the acceptable interior noise limit for new construction is 45 dB CNEL.

State of California General Plan Guidelines 2017

Though not adopted by law, the State of California General Plan Guidelines 2017, published by the California Governor’s Office of Planning and Research (OPR) (OPR Guidelines), provides guidance for the compatibility of projects within areas of specific noise exposure. The OPR Guidelines identify the suitability of various types of construction relative to a range of outdoor noise levels and provide each local community some flexibility in setting local noise standards that allow for the variability in community preferences. Findings presented in the Levels of Environmental Noise Document (EPA 1974) influenced the recommendations of the OPR Guidelines, most importantly in the choice of noise exposure metrics (i.e., Ldn or CNEL) and in the upper limits for the normally acceptable outdoor exposure of noise-sensitive uses.

The OPR Guidelines include a Noise and Land Use Compatibility Matrix which identifies acceptable and unacceptable community noise exposure limits for various land use categories. Where the “normally acceptable” range is used, it is defined as the highest noise level that should be considered for the construction of the buildings which do not incorporate any special acoustical treatment or noise mitigation. The “conditionally acceptable” or “normally unacceptable” ranges include conditions calling for detailed acoustical study prior to the construction or operation of the proposed project.

LOCAL REGULATIONS

City of Riverside General Plan

Table 5 shows the City’s noise level standards related to land use compatibility. This matrix does not provide noise/land use compatibility criteria for multiple family residential land uses. For the purposes of this analysis, the noise/land use compatibility criteria for infill single family residential land uses have been used. As shown in Table 5, infill single family residential land uses are considered “normally acceptable” where noise levels are not expected to exceed 65 dB CNEL, “conditionally acceptable” between 65-75 dB CNEL, “normally unacceptable” between 75-80 dB CNEL, and “conditionally unacceptable” where noise levels are expected to exceed 80 dB CNEL. These standards apply to the proposed project itself.

The City of Riverside General Plan also includes the following objectives and policies in regard to noise which apply to the proposed project.

Objective N-1 Minimize noise levels from point sources throughout the community and, wherever possible, mitigate the effects of noise to provide a safe and healthful environment.

New construction or development should generally not be undertaken, unless it can be demonstrated that noise reduction requirements can be employed to reduce noise impacts to an acceptable level. If new construction or development does proceed, a detailed analysis of noise reduction requirements must be made and needed noise insulation features inluded in the design.

Specified land use is satisfactory, based up the assumption that any building is of normal conventional construction, without any special noise insulation requirements.

New construction or development should be undertaken only after a detailed analysis of noise reduction requirements is made and needed noise insulation features included in design. Conventional constuction, but with closed windows and fresh air supply systems or air conditioning will normally suffice.

New construction or development should generally be discouraged. If new construction or development does proceed, a detailed analysis of noise reduction requirements must be made and needed noise insulation features included in design.

5. ANALYTICAL METHODOLOGY AND MODEL PARAMETERS

This section discusses the analysis methodologies used to assess noise impacts.

CONSTRUCTION NOISE MODELING

Construction noise will vary depending on the construction process, type of equipment involved, location of the construction site with respect to sensitive receptors, the schedule proposed to carry out each task (e.g., hours and days of the week) and the duration of the construction work.

Construction noise associated with the proposed project was calculated at the sensitive receptor locations, utilizing methodology presented in the Federal Transit Administration (FTA) Transit Noise and Vibration Impact Assessment Manual (2018) together with several key construction parameters, including: distance to each sensitive receiver, equipment usage, percent usage factor, and baseline parameters for the project site.

Distances to receptors were based on the acoustical center of the project site.

The equipment used to calculate the construction noise levels for each phase were based on the assumptions provided in the California Emissions Estimator Model (CalEEMod) modeling provided in the Air Quality, Global Climate Change, HRA, and Energy Impact Analysis prepared for the proposed project (Ganddini Group, Inc., 2025). For analysis purposes, the distance measured from the project site to sensitive receptors was assumed to be the acoustical center of the project site to the property line of residential properties with existing residential buildings. Sound emission levels associated with typical construction equipment as well as typical usage factors are provided in Table 8. Construction noise worksheets are provided in Appendix E.

OPERATIONAL NOISE MODELING

SoundPLAN Noise Model

The SoundPLAN acoustical modeling software was utilized to model future traffic noise levels at proposed project sensitive uses (e.g., residences). SoundPLAN is capable of evaluating stationary noise sources (e.g., parking lots, drive-thru menus, carwash equipment, vacuums, etc.) as well as mobile noise sources (e.g., vehicle traffic and trains. The SoundPLAN software utilizes algorithms (based on the inverse square law) to calculate noise level projections. The software allows the user to input specific noise sources, spectral content, sound barriers, building placement, topography, and sensitive receptor locations. In addition to the information provided below, noise modeling input and outputs assumptions are provided in Appendix F.

BNSF rail lines currently run parallel to the project site approximately 160 f from the northwestern property line. As discussed previously, while other residential and traffic background noise is readily noticeable, the passing of trains at this location dominates the noise environment and is the primary contributor to the CNEL.

For this reason, the 24-hour noise measurement taken on the project site (LTNM1 shown on Figure 5) was used to represent rail, vehicle traffic, and other incidental noise in the project environment. Hourly measurements as well as the CNEL are provided in Table 2. A line source was calibrated in the SoundPLAN noise model to represent the measured CNEL.

Expected increases in vehicle traffic along Mission Avenue or Commerce Street would not have an impact on the overall CNEL.

Existing and Existing Plus Project Traffic Noise Levels

Noise from vehicular traffic (Existing, Existing Plus Project, and Future) was modeled using a computer program that replicates the FHWA Traffic Noise Prediction Model (FHWA-RD-77-108). The FHWA model arrives at the predicted noise level through a series of adjustments to the Reference Energy Mean Emission Level (REMEL). Key model parameters and REMEL adjustments are presented below:
24 Iron Lofts Multifamily Residential
Noise Impact Analysis
25 19630

 Roadway classification (e.g., freeway, major arterial, arterial, secondary, collector, etc.);  Roadway active width (distance between the center of the outer most travel lanes on each side of the roadway);
 Average Daily Traffic (ADT) Volumes, Travel Speeds, Percentages of automobiles, medium trucks and heavy trucks;
 Roadway grade and angle of view;
 Site conditions (e.g., soft vs. hard); and
 Percentage of total ADT which flows each hour throughout a 24-hour period.

Traffic noise levels were calculated at the right-of-way based on distance from the centerline of the analyzed roadway. The modeling is theoretical and does not take into account any existing barriers, structures, and/or topographical features that may further reduce noise levels. Therefore, the modeled noise levels are shown for comparative purposes only to show the difference between with and without project conditions. The traffic noise calculation worksheets are included in Appendix G.

Project generated vehicle traffic is expected to utilize Mission Inn Avenue, 6th Street, and 5th Street to access the project site. Existing and project average daily vehicle trips (ADTs) were provided in the Iron Lofts Multifamily Residential Traffic Impact Analysis (TIA) prepared for the project (Ganddini Group, January 15, 2025).

Per the TIA, the project is anticipated to generate 1,425 new daily vehicle trips and 1,213 net new daily vehicle trips when taking into consideration the reduction of existing uses. Table 9 includes the modeled roadway segments as well as the average daily traffic volumes, posted speed limits, and vehicle mix utilized in this analysis.

GROUNDBORNE VIBRATION MODELING

Groundborne vibration modeling was performed using vibration propagation equations and construction equipment source levels obtained from the FTA Transit Noise and Vibration Impact Assessment Manual (2018).

Table 10 shows typical vibration levels associated with commonly used construction equipment based on data from the FTA.

There are several types of construction equipment that can cause vibration levels high enough to annoy persons in the vicinity and/or result in architectural or structural damage to nearby structures and improvements. For example, as shown in Table 10, a vibratory roller could generate up to 0.21 in/sec PPV at and operation of a large bulldozer could generate up to 0.089 PPV at a distance of 25 feet (two of the most vibratory pieces of construction equipment). Groundborne vibration at sensitive receptors associated with this equipment would drop off as the equipment moves away. For example, as the vibratory roller moves further than 100 feet from the sensitive receptors, the vibration associated with it would drop below 0.0026 in/sec PPV. It should be noted that these vibration levels are reference levels and may vary slightly depending upon soil type and specific usage of each piece of equipment. Groundborne vibration calculations are provided in Appendix H.

The fundamental equation used to calculate vibration propagation through average soil conditions and distance is as follows:

PPVequipment = PPVref (25/Drec)n

Where: PPVref = reference PPV at 25ft.

Drec = distance from equipment to receiver in ft.
n = 1.5 (the value related to the attenuation rate through ground)

6. NOISE AND VIBRATION IMPACTS

This section analyzes the significance of project-related noise and groundborne vibration impacts relative to standards established by the City of Riverside and other applicable agencies in the context of CEQA. Appendix G of the California Environmental Quality Act Guidelines (Title 14, Division 6, Chapter 3 of the California Code of Regulations) includes an environmental checklist that identifies issues upon which findings of significance should be made. The CEQA Environmental Checklist Appendix G, XIII. Noise, requires determination if the project would result in:

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

NOISE IMPACTS

Would the project result in:

Finding: Less Than Significant With Mitigation

In relation to the Environmental Checklist noise issue “a”, applicable standards established by the City of Riverside can be categorized into the following areas:

 Construction Noise
 Operational Noise

Project Construction

On-Site Equipment

Construction noise is regulated within the City of Riverside Municipal Code Section 7.35.020(G), which prohibits construction activities outside the hours of hours of 7:00 AM to 7:00 PM on weekdays, 8:00 AM to 5:00 PM on Saturdays, or at any time on Sundays or federal holidays. However, neither the City of Riverside General Plan or Municipal Code establish numeric maximum acceptable construction source noise levels at potentially affected receivers, which would allow for a quantified determination of what CEQA consists as a substantial temporary or periodic noise increase . Therefore, a numerical construction noise threshold based on the Federal Transit Administration (FTA) Transit Noise and Vibration Impact Assessment Manual is used for analysis of daytime construction impacts, as discussed below.

According to the FTA, local noise ordinances are typically not very useful in evaluating construction noise.

They usually relate to nuisance and hours of allowed activity, and sometimes specify limits in terms of maximum levels, but are generally not practical for assessing the impact of a construction project. Project construction noise criteria should account for the existing noise environment, the absolute noise levels during construction activities, the duration of the construction, and the adjacent land use. Due to the lack of 30 Iron Lofts Multifamily Residential
Noise Impact Analysis
31 19630
standardized construction noise thresholds, the FTA provides guidelines that can be considered reasonable criteria for construction noise assessment. The FTA considers a daytime (7:00 AM to 10:00 PM) exterior construction noise level of 80 dBA Leq for noise sensitive residential land uses and 85 dBA Leq for commercial uses. In addition, the FTA considers a nighttime (10:00 PM to 7:00 AM) exterior construction noise level of 70 dBA Leq for noise sensitive residential land uses and 85 dBA Leq for commercial uses.

Accordingly, the project would result in a significant impact if:

 Project construction occurs outside the hours of 7:00 AM to 7:00 PM on weekdays; 8:00 AM and 5:00 PM on Saturdays; at anytime on Sundays or federal holidays; or,  Project construction noise exceeds 80 dBA Leq during the daytime (7:00 AM to 10:00 PM) or 70 dBA L eq during the nighttime (10:00 PM to 7:00 AM) at residential uses; or,  Project construction noise exceeds 85 dBA L eq during the daytime (7:00 AM to 10:00 PM) or nighttime (10:00 PM to 7:00 AM) at commercial uses.

Project construction noise levels at nearby sensitive receptors were calculated using the FTA methodology.

Construction noise modeling worksheets for each phase are provided in Appendix E. Anticipated noise levels during each construction phase are presented in Table 11.

As shown in Table 11, modeled construction noise levels are forecast to reach up to 69.2 dBA L eq at the nearest existing commercial property line to the northwest, 68 dBA L eq at the nearest existing residential property line to the northeast, 75.2 dBA L eq at the nearest existing residential property line to the east, 68 dBA Leq at the nearest existing residential property line to the southeast, 68.6 dBA L eq at the nearest existing residential property line to the south, 67 dBA L eq at the nearest existing commercial property line to the southwest, and 72.3 dBA Leq at the nearest existing commercial property line to the west of the project site.

Based on the modeled construction noise levels (see Appendix E), construction noise levels will not exceed the daytime FTA residential construction noise standards of 80 dBA L eq for residential uses and 85 dBA L eq for commercial uses. In addition, the modeled construction noise levels do not exceed the nighttime FTA construction noise threshold of 85 dBA L eq for commercial uses. However, the nighttime FTA construction noise threshold of 70 dBA L eq for residential uses will potentially be exceeded at the residential uses to the east of the project site if construction activities occur between 10:00 PM and 7:00 AM.

Project construction will not occur outside of the hours outlined in the City of Riverside Municipal Code Section 7.35.020(G) (7:00 PM to 7:00 AM on weekdays and 5:00 PM and 8:00 AM on Saturdays); therefore, the project would not undergo construction activities during the FTA noise sensitive nighttime hours of 10:00 PM and 7:00 AM. Therefore, the project is not expected to exceed established standards relating to construction noise. The project impact would be less than significant, no mitigation is required.

Notwithstanding the above, best management practices (BMPs) provided in the Project Description can be added to project plans and in contract specifications to minimize construction noise emanating from the proposed project.

Off-Site Vehicle Trips

Neither the City of Riverside’s General Plan nor the City’s Municipal Code establishes quantitative thresholds for the increase in ambient noise levels associated with project generated vehicle trips during project construction. According to the FHWA, traffic volumes would need to double in order to result in a barely perceptible increase in noise levels (3 dBA)2. As discussed in Section 4 of this report, the FICON has published thresholds that can be used to assess whether project generated transportation noise may result in a substantial increase in noise levels. Existing measured ambient noise levels along Mission Inn Avenue and

Noise Impact Analysis
32 19630
Commerce Street in the vicinity of the project site were 71.7 dBA L eq and 64.6 dBA L eq, respectively .

Therefore, a project traffic induced noise increase of 3 dBA or more may be considered to be substantial.

Construction truck trips would occur throughout the construction period. Mission Inn Avenue currently handles between approximately 2,700 and 14,00 average daily vehicle trips and Commerce Street handles between approximately 1,000 to 2,000 average daily vehicle trips in the vicinity of the project site.3 According to the Iron Lofts Multifamily Residential Project Air Quality, Global Climate Change, Health Risk Assessment, and Energy Impact Analysis (Ganddini Group, Inc., 2023), the greatest number of construction-related vehicle trips per day would be during building construction at up to approximately 248 vehicle trips per day (216 for worker trips and 32.1 for vendor trips). Given the project site’s proximity to 91 Freeway, it is anticipated that vendor and/or haul truck traffic would take the most direct route to the appropriate freeway ramps. Therefore, the addition of project vendor/haul trucks and worker vehicles per day along off-site roadway segments would not be anticipated to result in a doubling of traffic volumes necessary to increase noise levels by 3 dBA. Off- site project generated construction vehicle trips would result in a negligible noise level increase and would not result in a substantial increase in ambient noise levels. Impacts would be less than significant. No mitigation measures are required.

Project Operational Noise

Offsite Operational Noise Sources

Neither the City of Riverside’s General Plan nor the City’s Municipal Code establishes quantitative thresholds for the increase in ambient noise levels associated with project generated vehicle trips which would allow for a quantified determination of what would qualify as a substantial temporary or periodic noise increase under CEQA. Project generated vehicle traffic will result in incremental increases in noise levels along affected road segments.

The City of Riverside General Plan establishes that noise levels of up to 60 dBA CNEL are considered “normally acceptable” and of up to 65 dBA CNEL are considered “conditionally acceptable” for single-family residential; noise levels of up to 65 dBA CNEL are considered “normally acceptable” and of up to 75 dBA CNEL are considered “conditionally acceptable” for infill single-family residential; noise levels of up to 60 dBA CNEL are considered “normally acceptable” and of up to 70 dBA CNEL are considered “conditionally acceptable” for commercial uses; and noise levels of up to 70 dBA CNEL are considered “normally acceptable” and of up to 80 dBA CNEL are considered “conditionally acceptable” for industrial uses (Table 5).

California courts have rejected use of what is effectively a single “absolute noise level” threshold of significance (e.g., exceed 65 dBA CNEL) on the grounds that the use of such a threshold fails to consider the magnitude or severity of increases in noise levels attributable to the project in different environments (see King and Gardiner Farms, LLC v. County of Kern (2020) 45 Cal.App.5th 814). California courts have also upheld the use of “ambient plus increment” thresholds for assessing project noise impacts as consistent with CEQA, noting however, that the severity of existing noise levels should not be ignored by incorporating a smaller incremental threshold for areas where existing ambient noise levels were already high (see Mission Bay Alliance v. Office of Community Investment and Infrastructure (2016) 6 Cal.App.5th 160).

Based on the case described above, it is important to consider impacts in light of the existing ambient noise levels and the adopted agency standards, which in this case includes the City’s compatibility standards.

Furthermore, it is widely accepted that the average healthy human ear can barely perceive changes of 3 dBA in an outdoor environment and that a change of 5 dBA is readily perceptible. 4

As stated previously, FICON has published thresholds that can be used to assess whether a project may result in a substantial increase in noise levels where a lead agency has not adopted their own, as follows:

 If project generated vehicle traffic results in an increase of 5 dB or more where existing ambient noise levels are less than 60 dB CNEL at existing sensitive noise receptors; or

 If project generated vehicle traffic results in an increase of 3 dB or greater where existing ambient noise levels are 60 to 65 dBA CNEL at existing sensitive noise receptors; or

 If project generated vehicle traffic results in an increase of 1.5 dB or more where existing ambient noise levels are greater than 65 dBA CNEL at existing sensitive noise receptors.

Roadway noise levels were calculated at roadways included in the Iron Lofts Multifamily Residential Project Traffic Impact Analysis (Ganddini Group, Inc., January 15, 2025) based on the FHWA Traffic Noise Prediction Model methodology. During operation, the proposed project is expected to generate approximately 1,213 net average daily trips with 90 trips during the AM peak-hour and 72 trips during the PM peak-hour. Roadway noise levels were calculated for the following scenarios:
 Existing (without Project): This scenario refers to existing year traffic noise conditions.  Existing Plus Project: This scenario refers to existing year plus project traffic noise conditions.

Table 12 shows the change in existing roadway noise levels with the addition of project-generated operational trips. FHWA Traffic Noise Prediction Model calculation worksheets are provided in Appendix G.

Modeled existing traffic noise levels range between 46-75 dBA CNEL and the modeled Existing Plus Project traffic noise levels range between 49-75 dBA CNEL at the right-of-way of each study roadway segment. The addition of project trips is not expected to change noise levels in excess of the applicable threshold at any of the study roadway segments (see Table 12 ). The project impact is less than significant; no mitigation is required.

Transportation Source Noise Impacts to the Project

As shown in Table 5, per the City of Riverside General Plan noise levels of up to 60 dBA CNEL are considered “normally acceptable” and up to 65 dBA CNEL are considered “conditionally acceptable” for residential uses.

Facades with anticipated noise levels of 65 dBA CNEL are expected to have interior noise levels that do not exceed 45 dBA CNEL. This is based on the assumption that heating and ventilation systems will be provided in order to allow for a windows-closed condition.

As shown in Figure 6, transportation related noise is expected to range between 61 and 72 dBA CNEL at the proposed residential buildings. As shown in Table 5, development of infill residential land uses are considered to be “normally acceptable” in areas where noise levels reach up to 65 dBA CNEL. With implementation of the following mitigation measures.

Mitigation Measure 1
Windows and glass doors shall have STC ratings as presented in Table 13. Where no STC is listed, standard windows that meet California Building Code requirements will suffice.

GROUNDBORNE VIBRATION IMPACTS

Would the project result in:

b) Generation of excessive groundborne vibration or groundborne noise levels?

33 Iron Lofts Multifamily Residential
Noise Impact Analysis
34 19630
Finding: Less Than Significant

In relation to the Environmental Checklist noise issue “b”, the City of Riverside has not established thresholds of significance concerning groundborne vibration. In the absence of City-established thresholds, groundborne vibration impacts are based on guidance from the Federal Transit Administration (FTA) Transit Noise and Vibration Impact Assessment Manual (FTA, September 2018) (see Regulatory Setting section). Accordingly, the project would result in a significant impact if:

 Groundborne vibration levels generated by the project have the potential to cause architectural damage at nearby buildings by exceeding the following PPV:
□ 0.10 in/sec (90 VdB) at buildings extremely susceptible to vibration damage □ 0.20 in/sec (94 VdB) at non-engineered timber and masonry buildings □ 0.30 in/sec (98 VdB) at engineered concrete and masonry (no plaster) buildings □ 0.50 in/sec (102 VdB) at reinforced-concrete, steel or timber (no plaster) buildings  Groundborne vibration levels generated by the project have the potential to cause annoyance at sensitive receptors by exceeding 80 VdB.

Groundborne vibration modeling worksheets are provided in Appendix H.

Construction-Related Vibration Impacts

Existing structures in the immediate vicinity of the project site include the residential buildings located as close as approximately 15 feet to the east, 34 feet to the east, 79 feet to the east, 118 feet to the southeast, and 104 feet to the south and the commercial building located as close as approximately 55 feet to the northwest of the project site boundaries).

Groundborne vibration levels associated with project construction are provided in Table 14. As shown in Table 14, the threshold of 0.2 PPV in/sec will be exceeded at the residential uses to the east (along 5 th Street and 6th Street) of the project site. The following measure is recommended to ensure groundborne vibration generated by project construction does not cause architectural damage or severe annoyance to nearby buildings:

Mitigation Measure 2
The use of vibrator rollers, or other similar vibratory equipment, within 26 feet of residential structures surrounding the project site is to be prohibited.

The threshold for annoyance due to vibration (80 VdB at offsite sensitive uses) could be exceeded at the existing residential land uses surrounding the project site and residents may be temporarily annoyed. However, the impact would only occur when construction equipment is operating within 74 feet of the residential structures and only during daytime hours and will be temporary.

Therefore, project construction would not result in the exposure of persons to excessive groundborne vibration and impacts would be less than significant with incorporation of mitigation measure 2.

Rail-Related Vibration Impacts

The proposed project site is located approximately 170 feet southeast of the BNSF rail line. The closest proposed building is approximately 12 feet from the property line. Using the Generalized Ground Surface Vibration Equation provided in the FTA Transit Noise and Vibration Assessment Manual (2018), groundborne vibration associated with freight rail pass-bys would reach up to 53 VdB at the nearest proposed building which falls below any of the FTA criteria for potential damage to buildings. This impact would be less than significant. No mitigation is necessary.

As shown in Table 3, potential annoyance inside the proposed residential buildings would be at a level of 80 Vdb (0.04 PPV inches per second). As stated above, rail induced groundborne vibration would not exceed 53 VdB and therefore, impacts related to annoyance would be less than significant. No mitigation is required.

AIR TRAFFIC IMPACTS

Would the project result in:

c) For a project located within the vicinity of a private airstrip or an airport land use plan or, where such a plan has not been adopted, within two miles of a public airport or public use airport, would the project expose people residing or working in the area to excessive noise levels?

Finding: No Impact

The closest airports to the project site are the Flabob Airport, with airport runways located as close as approximately 2.29 miles to the northwest of the project site, and the Riverside Municipal Airport, with airport runways located as close as approximately 4.4 miles to the southwest of the project site. Per the Riverside County Airport Land Use Compatibility Plan (ALUCP) Policy Document Map FL-3 (December 2004), the project site is well outside the 55 dBA CNEL noise contour for the Flabob Airport. The Riverside County ALUCP Policy Document (March 2005) Map RI-3, shows that the project site is also well outside the 55 dBA CNEL noise contour for the Riverside Municipal Airport. 5 The project would not expose people residing or working in the project area to excessive noise levels associated with airports. This impact would be less than significant. No mitigation is required.

(3) The mitigation measure needed for architectural damage would include prohibiting the use of vibratory rollers, or other similar vibratory equipment, within 26 feet of residential structures surrounding the project site. (2) The FTA identifies the threshold at which there is a risk to “architectural” damage to non-engineered timber and masonry buildings as a PPV of 0.2 in/sec (see Table 4). In addition, the FTA identifies a vibration annoyance threshold of 72 VdB for residential uses (see Table 3). Per the FTA Transit Noise and VIbration Impact Assessment Manual (September 2018), commercial uses are not considered vibration-sensitive land uses; therefore, the annoyance threshold does not apply to commercial uses.
(1) Vibration levels are provided in PPV in/sec for architectural damage and VdB for annoyance.

Term Definition
Ambient Noise
Level
The all-encompassing noise environment associated with a given environment, at a specified time, usually a composite of sound from many sources, at many directions, near and far, in which usually no particular sound is dominant.

A-Weighted Sound
Level, dBA
The sound level obtained by use of A-weighting. 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.

CNEL
Community Noise Equivalent Level. CNEL is a weighted 24-hour noise level that is obtained by adding five decibels to sound levels in the evening (7:00 PM to 10:00 PM), and by adding ten decibels to sound levels at night (10:00 PM to 7:00 AM). This weighting accounts for the increased human sensitivity to noise during the evening and nighttime hours.

Decibel, dB
A logarithmic unit of noise level measurement that relates the energy of a noise source to that of a constant reference level; the number of decibels is 10 times the logarithm (to the base 10) of this ratio.

DNL, Ldn
Day Night Level. The DNL, or Ldn is a weighted 24-hour noise level that is obtained by adding ten decibels to sound levels at night (10:00 PM to 7:00 AM). This weighting accounts for the increased human sensitivity to noise during the nighttime hours.

Equivalent
Continuous Noise
Level, Leq
A level of steady state sound that in a stated time period, and a stated location, has the same A-weighted sound energy as the time-varying sound.

Fast/Slow Meter
Response
The fast and slow meter responses are different settings on a sound level meter. The fast response setting takes a measurement every 100 milliseconds, while a slow setting takes one every second.

Frequency, Hertz In a function periodic in time, the number of times that the quantity repeats itself in one second (i.e., the number of cycles per second).

L02, L08, L50, L90 The A-weighted noise levels that are equaled or exceeded by a fluctuating sound level, 2 percent, 8 percent, 50 percent, and 90 percent of a stated time period, respectively.

Lmax, Lmin
Lmax is the RMS (root mean squared) maximum level of a noise source or environment measured on a sound level meter, during a designated time interval, using fast meter response. Lmin is the minimum level.

Offensive/
Offending/Intrusive
Noise
The noise that intrudes over and above the existing ambient noise at a given location.

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

Root Mean Square
(RMS)
A measure of the magnitude of a varying noise source quantity. The name derives from the calculation of the square root of the mean of the squares of the values. It can be calculated from either a series of lone values or a continuous varying function.
