Environmental Noise & Vibration Assessment
The Preserve Residential Development – Rancho Cordova, California
Introduction
The proposed The Preserve Residential Development (project) is located north of Douglas Road, in between Security Park Drive and Raymer Way in Rancho Cordova, California. The project proposes the development of 434 single-family residential lots, public parks, and preserve area on a currently undeveloped 284-acre parcel. The proposed development is located within the Sunrise Douglas Community Plan. Existing land uses in the project vicinity include residential to the south, undeveloped residential to the west, and agricultural to the north and east. The project site location and site plan are shown on Figures 1 and 2, respectively.
The purposes of this assessment are to quantify the existing noise and vibration environments, identify potential noise and vibration impacts resulting from the project, identify appropriate mitigation measures, and provide quantitative and qualitative analyses of impacts associated with the project. Specifically, impacts are identified if project-related activities would cause a substantial increase in ambient noise or vibration levels at existing sensitive uses in the project vicinity, or if traffic or project generated noise or vibration levels would exceed applicable Rancho Cordova standards at existing or proposed sensitive uses within the project vicinity.
Noise and Vibration Fundamentals
Noise
Noise is often described as unwanted sound. Sound is defined as any pressure variation in air that the human ear can detect. If the pressure variations occur frequently enough (at least 20 times per second), they can be heard and are designated as sound. The number of pressure variations per second is called the frequency of sound and is expressed as cycles per second, or Hertz (Hz). Definitions of acoustical terminology are provided in Appendix A.
Measuring sound directly in terms of pressure would require a very large and awkward range of numbers. To avoid this, the decibel scale was devised. The decibel scale uses the hearing threshold (20 micropascals of pressure) as a point of reference, defined as 0 dB. Other sound pressures are then compared to the reference pressure, and the logarithm is taken to keep the numbers in a practical range. The decibel scale allows a million-fold increase in pressure to be expressed as 120 dB. Another useful aspect of the decibel scale is that changes in decibel levels correspond closely to human perception of relative loudness. Noise levels associated with common noise sources are provided in Figure 3.
The perceived loudness of sounds is dependent upon 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 filtering the frequency response of a sound level meter by means of the standardized A-weighting network. There is a strong correlation between A-weighted sound levels (expressed as dBA) and community response to noise. For this reason, the A-weighted sound level has become the standard tool of environmental noise assessment. All noise levels reported in this section are in terms of A-weighted levels.

Environmental Noise & Vibration Assessment
The Preserve Residential Development – Rancho Cordova, California
Community noise is commonly described in terms of the ambient noise level, which is defined as the all-encompassing noise level associated with a given noise environment. A common statistical tool to measure the ambient noise level is the average, or equivalent, sound level (Leq).
The Leq is the foundation of the day-night average noise descriptor, DNL (or Ldn), and shows very good correlation with community response to noise.
The day-night average sound level (DNL) is based on the average noise level over a 24-hour day, with a +10-decibel weighting applied to noise occurring during nighttime (10:00 PM to 7:00 AM) hours. The nighttime penalty is based on the assumption that people react to nighttime noise exposures as though they were twice as loud as daytime exposures. Because DNL represents a 24-hour average, it tends to disguise short-term variations in the noise environment.
Vibration
Vibration is like noise in that it involves a source, a transmission path, and a receiver. While vibration is related to noise, it differs in that noise is generally considered to be pressure waves transmitted through air, while vibration is usually associated with transmission through the ground or structures. As with noise, vibration consists of an amplitude and frequency. A person’s response to vibration will depend on their individual sensitivity as well as the amplitude and frequency of the source.
Vibration can be described in terms of acceleration, velocity, or displacement. A common practice is to monitor vibration in terms of velocity in inches per second peak particle velocity (IPS, PPV) or root-mean-square (VdB, RMS). Standards pertaining to perception as well as damage to structures have been developed for vibration in terms of peak particle velocity as well as RMS velocities.
As vibrations travel outward from the source, they excite the particles of rock and soil through which they pass and cause them to oscillate. Differences in subsurface geologic conditions and distance from the source of vibration will result in different vibration levels characterized by different frequencies and intensities. In all cases, vibration amplitudes will decrease with increasing distance. The maximum rate, or velocity of particle movement, is the commonly accepted descriptor of the vibration “strength”.
Human response to vibration is difficult to quantify. Vibration can be felt or heard well below the levels that produce any damage to structures. The duration of the event has an effect on human response, as does frequency. Generally, as the duration and vibration frequency increase, the potential for adverse human response increases.
According to the Transportation and Construction-Induced Vibration Guidance Manual (Caltrans, June 2004), operation of construction equipment and construction techniques generate ground vibration. Traffic traveling on roadways can also be a source of such vibration. At high enough amplitudes, ground vibration has the potential to damage structures and/or cause cosmetic damage. Ground vibration can also be a source of annoyance to individuals who live or work close to vibration-generating activities. However, traffic, rarely generates vibration amplitudes high enough to cause structural or cosmetic damage.

Environmental Setting – Existing Ambient Noise and Vibration Environment
Existing Noise-Sensitive Land Uses in the Project Vicinity Noise-sensitive land uses are generally defined as locations where people reside or where the presence of unwanted sound could adversely affect the primary intended use of the land. Places where people live, sleep, recreate, worship, and study are generally considered to be sensitive to noise because intrusive noise can be disruptive to these activities.
The existing noise-sensitive land uses which would potentially be affected by the project consist of residential uses. Specifically, existing single-family residential land uses are located to the south the proposed development (within a subdivision). In addition, existing residences are sparsely located on agriculturally zoned properties north of the project. Although agricultural uses are typically not considered to be noise-sensitive, residences located on agricultural lands would be. The project area and surrounding land uses are shown on Figure 1.
Existing Traffic Noise Levels along Project Area Roadway Network The FHWA Traffic Noise Model (FHWA-RD-77-108) was used to develop existing noise contours expressed in terms of DNL for major roadways within the project study area. The FHWA Model predicts hourly Leq values for free-flowing traffic conditions. Estimates of the hourly distribution of traffic for a typical 24-hour period were used to develop DNL values from Leq values.
Traffic data in the form of AM and PM peak hour movements for existing conditions were obtained from the client prepared by Kimley-Horn & Associates, Inc. Average daily traffic volumes were conservatively estimated by applying a factor of 5 to the sum of AM and PM peak hour conditions.
Using these data and the FHWA Model, traffic noise levels were calculated. The traffic noise level at 100 feet from the roadway centerline and distances from the centerlines of selected roadways to the 60 dB, 65 dB, and 70 dB DNL contours are summarized in Table 1.
In many cases, the actual distances to noise level contours may vary from the distances predicted by the FHWA Model. Factors such as roadway curvature, roadway grade, shielding from local topography or structures, elevated roadways, or elevated receivers may affect actual sound propagation. It is also recognized that existing sensitive land uses within the project vicinity are located varying distances from the centerlines of the local roadway network. The 100-foot reference distance is utilized in this assessment to provide a reference position at which changes in existing and future traffic noise levels resulting from the project can be evaluated. Appendix B contains the FWHA Model inputs for existing conditions.

Environmental Noise & Vibration Assessment
The Preserve Residential Development – Rancho Cordova, California
Existing Overall Ambient Noise Environment within the Project Area The existing ambient noise environment within the project area is defined primarily by noise from traffic on Grant Line Road and Raymer Way. To generally quantify existing ambient noise levels within the project area, two long-term (48-hour) ambient noise surveys were conducted from July 10-12, 2019 and one short-term (15-minute) ambient noise survey was conducted on July 10, 2019. The ambient noise measurement locations are shown on Figure 1. Photographs of the noise survey locations are provided in Appendix C.
Larson Davis Laboratories (LDL) Model 820 precision integrating sound level meters were used to complete the noise level measurement surveys. The meters were calibrated before use with an LDL Model CA200 acoustical calibrator to ensure the accuracy of the measurements. The equipment used meets all specifications of the American National Standards Institute requirements for Type 1 sound level meters (ANSI S1.4).
The long-term ambient noise survey results are summarized in Table 2. The detailed results of the long-term noise survey are contained in Appendix D in tabular format and graphically in Appendix E. A summary of the short-term noise measurement results is provided in Table 3.

The Table 2 data indicate that existing ambient noise levels at the project site were satisfactory relative to the Rancho Cordova General Plan normally acceptable and conditionally acceptable exterior traffic noise level standards of 60 and 65 dB DNL for new residential land uses, respectively. Results from the short-term noise survey indicate that the measured average and maximum noise levels at site ST-1 were 42 dB Leq and 58 dB Lmax, respectively (Table 3).
Existing Ambient Vibration Environment
During a site visit on July 10, 2019, vibration levels were below the threshold of perception at the project site. Nonetheless, to quantify existing vibration levels at the project site, BAC conducted short-term (15-minute) vibration measurements at the project site on July 10, 2019. The vibration measurement sites are shown on Figure 1. Photographs of the vibration measurement sites are shown in Appendix C.
A Larson-Davis Laboratories Model LxT precision integrating sound level meter equipped with a vibration transducer was used to complete the measurements. The results are summarized below in Table 4.

Regulatory Setting: Criteria for Acceptable Noise and Vibration Exposure
Federal
The City of Rancho Cordova General Plan establishes criteria for assessing noise impacts associated with increases in ambient noise levels from new roadway projects. However, the City does not currently have criteria for assessing noise impacts associated with increases in ambient noise levels from project-generated traffic within the project vicinity. As a result, the following federal noise criteria established by the Federal Interagency Commission on Noise (FICON) was applied to the project.

Federal Interagency Commission on Noise (FICON)
The Federal Interagency Commission on Noise (FICON) has developed a graduated scale for use in the assessment of project-related noise level increases. The criteria shown in Table 5 was developed by FICON as a means of developing thresholds for impact identification for project-related noise level increases. The FICON standards have been used extensively in recent years by the authors of this section in the preparation of the noise sections of Environmental Impact Reports that have been certified in many California cities and counties.
The use of the FICON standards are considered conservative relative to thresholds used by other agencies in the State of California. For example, the California Department of Transportation (Caltrans) requires a project-related traffic noise level increase of 12 dB for a finding of significance, and the California Energy Commission (CEC) considers project-related noise level increases between 5 to 10 dB significant, depending on local factors. Therefore, the use of the FICON standards, which set the threshold for finding of significant noise impacts as low as 1.5 dB, provides a very conservative approach to impact assessment for this project.
Table 5
Significance of Changes in Cumulative Noise Exposure
Ambient Noise Level Without Project (Ldn or CNEL) Change in Ambient Noise Level Due to Project <60 dB +5.0 dB or more
60 to 65 dB +3.0 dB or more
>65 dB +1.5 dB or more
Source: Federal Interagency Committee on Noise (FICON)
Based on the FICON research, as shown in Table 5, a 5 dB increase in noise levels due to a project is required for a finding of significant noise impact where ambient noise levels without the project are less than 60 dB. Where pre-project ambient conditions are between 60 and 65 dB, a 3 dB increase is applied as the standard of significance. Finally, in areas already exposed to higher noise levels, specifically pre-project noise levels in excess of 65 dB, a 1.5 dB increase is considered by FICON as the threshold of significance.
State of California
California Environmental Quality Act (CEQA)
The State of California has established regulatory criteria that are applicable to this assessment.
Specifically, Appendix G of the State of California Environmental Quality Act (CEQA) Guidelines are used to assess the potential significance of impacts pursuant to local General Plan policies, Municipal Code standards, or the applicable standards of other agencies. According to Appendix G of the CEQA guidelines, the project would result in a significant noise or vibration impact if the following occur:
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 other applicable standards of other agencies? ITEM 11.1. ATTACHMENT 4

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 project area to excessive noise levels?
It should be noted that audibility is not a test of significance according to CEQA. If this were the case, any project which added any audible amount of noise to the environment would be considered significant according to CEQA. Because every physical process creates noise, the use of audibility alone as significance criteria would be unworkable. CEQA requires a substantial increase in noise levels before noise impacts are identified, not simply an audible change.
California Department of Transportation (Caltrans)
The City of Rancho Cordova does not currently have adopted standards for groundborne vibration. As a result, the vibration impact criteria developed by the California Department of Transportation (Caltrans) was applied to the project. The Caltrans criteria applicable to damage and annoyance from transient and continuous vibration typically associated with construction activities are presented in Tables 6 and 7. Equipment or activities typical of continuous vibration include: excavation equipment, static compaction equipment, tracked vehicles, traffic on a highway, vibratory pile drivers, pile-extraction equipment, and vibratory compaction equipment.
Equipment or activities typical of single-impact (transient) or low-rate repeated impact vibration include impact pile drivers, blasting, drop balls, “pogo stick” compactors, and crack-and-seat equipment (California Department of Transportation 2013).

1 Where the location of outdoor activity areas is unknown, the exterior noise level standard shall be applied to the property line of the receiving land use. Where it is not practical to mitigate exterior noise levels at patio or balconies of apartment complexes, a common area such as a pool or recreation area may be designated as the outdoor activity area. 2 As determined for a typical worst-case hour during periods of use. 3 Where it is not possible to reduce noise in outdoor activity areas to 60 dB Ldn/CNEL or less using a practical application of the best-available noise reduction measures, an exterior noise level of up to 65 dB Ldn/CNEL may be allowed provided that available exterior noise level reduction measures have been implemented and interior noise levels are in compliance with this table. 4 In the case of hotel/motel facilities or other transient lodging, outdoor activity areas such as pool areas may not be included in the project design. In these cases, only the interior noise level criterion will apply. 5 The intent of this noise standard is to provide increased protection against sleep disturbance for residences located near railroad tracks.

continue work after 8:00 p.m., and to operate machinery and equipment necessary until completion of the specific work in progress can be brought to conclusion under conditions which will not jeopardize inspection acceptance or create undue financial hardships for the contractor or owner.
It should be noted that although not specifically identified in the Rancho Cordova Municipal Code, the Noise Element of the Rancho Cordova General Plan states that activities conducted on public parks are generally considered to be exempt from the noise standards established in the City’s Noise Ordinance.
Impacts and Mitigation Measures
Thresholds of Significance
For the purposes of this report, a noise and vibration impact is considered significant if the project would result in:
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 other applicable standards of other agencies; or Generation of excessive groundborne vibration or groundborne noise levels; or 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 project site is not within the vicinity of a private airstrip, an airport land use plan, or within two miles of a public airport. Therefore, the last threshold listed above is not discussed further.
The following criteria based on standards established by the Federal Interagency Commission on Noise (FICON), California Department of Transportation (Caltrans), Rancho Cordova General Plan and Rancho Cordova Municipal Code were used to evaluate the significance of environmental noise and vibration resulting from the project:
A significant noise impact would be identified if the project would expose persons to or generate noise levels that would exceed applicable noise standards presented in the Rancho Cordova General Plan or Rancho Cordova Municipal Code. A significant impact would be identified if off-site traffic noise exposure or on-site activities generated by the project would substantially increase noise levels at existing sensitive receptors in the vicinity. A substantial increase would be identified relative to the FICON standards provided in Table 5.
A significant impact would be identified if project construction activities or proposed onsite operations would expose noise-sensitive receptors to excessive groundborne ITEM 11.1. ATTACHMENT 4

vibration levels. Specifically, an impact would be identified if groundborne vibration levels due to these sources would exceed the Caltrans vibration impact criteria.
Noise Impacts Associated with Project-Generated Increases in Off-Site Traffic With development of the project, traffic volumes on the local roadway network will increase.
Those increases in daily traffic volumes will result in a corresponding increase in traffic noise levels at existing uses located along those roadways. The FHWA Model was used with traffic input data from the traffic impact analysis (prepared by Kimley-Horn & Associates, Inc.) to predict project traffic noise level increases relative to Existing (2019) and Cumulative (2035) conditions.
Impact 1: Increases in Existing Traffic Noise Levels due to the Project Traffic data in the form of AM and PM peak hour movements for Existing and Existing Plus Project conditions in the project area roadway network were obtained from the project transportation impact analysis completed by Kimley-Horn & Associates, Inc. Average daily traffic (ADT) volumes were conservatively estimated by applying a factor of 5 to the sum of AM and PM peak hour conditions.
Existing versus Existing Plus Project traffic noise levels on the local roadway network are shown in Table 12. The following section includes an assessment of predicted traffic noise levels relative to the FICON increase significance noise criteria identified in Table 5. The Table 12 data are provided in terms of DNL (Ldn) at a standard distance of 100 feet from the centerlines of the project-area roadways. Appendix B contains the FWHA Model inputs.

As indicated in Table 12, project-generated traffic would not result in a substantial increase of traffic noise levels on the local roadway network relative to the FICON significance criteria identified in Table 5. As a result, off-site traffic noise impacts related to increases in traffic resulting from the implementation of the project (Existing vs. Existing Plus Project conditions) are identified as being less than significant.

The Table 13 data indicate that project-generated traffic would not result in a substantial increase of traffic noise levels on the local roadway network relative to the FICON significance criteria identified in Table 5. As a result, off-site traffic noise impacts related to increases in traffic resulting from the implementation of the project (Cumulative vs. Cumulative Plus Project conditions) are identified as being less than significant.
Noise Impacts Associated with Proposed Uses of the Development The project proposes the development of approximately 434 single-family lots, public parks, and preserve area. Specifically, the proposed project would preserve approximately 180 acres of open space that would be deeded to a third-party conservation entity, as well as for include the creation of approximately 23 acres of public parks north of the proposed residences. The locations of the proposed park and preserve areas are shown on Figure 2. The primary noise sources associated with proposed uses of the development have been identified as public park activities. An assessment of project-related park activity noise levels at the nearest existing noisesensitive uses follows. The nearest existing noise-sensitive uses to the development have been identified as a single-family residence located on an agriculturally zoned parcel to the northwest, and single-family residences located within a subdivision to the south (shown on Figure 1).
As noted previously, the Rancho Cordova General Plan Noise Element states that activities conducted on public parks are generally considered to be exempt from the noise standards established in the City’s Municipal Code (Noise Ordinance). As a result, the following assessment of project-related public park activity noise level exposure at the nearest existing noise-sensitive uses focuses on compliance with applicable Rancho Cordova General Plan noise level criteria only.
Impact 3: Public Park Noise at Existing Noise-Sensitive Uses According to the project site plans (Parks Exhibit, dated December 11, 2018), the project proposes two large parks at the north and northeast ends of the development. Figure 2 shows the locations of the proposed parks, identified as Parks 1 and 2. Noise generated by public parks vary depending on whether the parks are intended for passive or active use. Passive use includes picnic and sitting areas whereas active use incudes playing fields and play structures. Although the project site plans illustrate the locations of the proposed public parks, the specific park use ITEM 11.1. ATTACHMENT 4

types are unknown at the time of writing this report. To provide a conservative estimate of project park noise exposure at existing noise-sensitive uses, it was assumed for the purposes of this analysis that the proposed public parks would have active uses. According to BAC file data, parks consisting of active uses (playing fields) have noise levels of approximately 50 dB Leq and 70 dB Lmax at a distance of 100 feet (Appendix F).
Based on the reference noise levels presented above, and assuming standard spherical spreading loss (-6 dB per doubling of distance), park activity noise exposure at the nearest existing noise-sensitive uses (single-family residences) was calculated. The results of those calculations are provided in Table 14.
Because park activities would likely consist of human speech (i.e., shouting and cheering during activities), noise associated with park activities would be subject to the Rancho Cordova General Plan’s more restrictive daytime and nighttime hourly average noise level standards of 50 and 40 dB Leq (respectively) shown in Table 8. However, it is reasonable to assume that public park hours would be restricted to daytime hours only (7:00 a.m. to 10:00 p.m.). Therefore, project park noise exposure at the nearest existing noise-sensitive uses was assessed relative to the General Plan daytime hourly average noise level standard of 50 dB Leq.

As indicated in Table 14, project park noise level exposure is predicted to satisfy the applicable Rancho Cordova General Plan daytime noise level standard at the nearest existing noisesensitive uses (single family residential uses to the south and northwest of the project site).
Because project park activity noise level exposure is predicted to satisfy the applicable Rancho Cordova General Plan noise level criterion, this impact is identified as being less than significant.
Noise Impacts Associated with Project Construction Activities Impact 4: Project Construction Noise Levels at Existing Noise-Sensitive Uses During project construction, heavy equipment would be used for grading excavation, paving, and building construction, which would increase ambient noise levels when in use. Noise levels would vary depending on the type of equipment used, how it is operated, and how well it is maintained.

Noise exposure at any single point outside the project work area would also vary depending upon the proximity of equipment activities to that point. The nearest existing noise-sensitive uses (single-family residential within the subdivision to the south) are located approximately 25 feet from where construction activities would occur within the development.
Table 15 includes the range of maximum noise levels for equipment commonly used in general construction projects at full-power operation at a distance of 50 feet. Not all of these construction activities would be required of this project. The Table 15 data also include predicted maximum equipment noise levels at the nearest existing residential uses located approximately 25 feet away, which assume a standard spherical spreading loss of 6 dB per doubling of distance.

Source: Federal Transit Administration Noise and Vibration Impact Assessment Manual, Table 7-1 (2018) Based on the equipment noise levels in Table 15, worst-case on-site project construction equipment noise levels at the nearest existing residential uses located 25 feet away are expected to range from approximately 82 to 91 dB. Thus, it is possible that a portion of the project construction equipment could result in substantial short-term increases over ambient maximum noise levels at the nearest existing noise-sensitive uses. Furthermore, it is possible that those ITEM 11.1. ATTACHMENT 4

noise levels could exceed the applicable Rancho Cordova General Plan and Municipal Code noise level limits.
As noted in the Regulatory Setting Section of this report, Section 6.68.090 of the Rancho Cordova Municipal Code exempts noise sources associated with construction provided such activities do not take place between specific hours. However, if construction activities are proposed during the hours not exempted by Municipal Code Section 6.68.090, noise levels generated by construction activities would likely exceed the maximum noise level standards identified in Table 15 at the nearest existing residential uses.
Because project construction equipment noise levels could potentially exceed the applicable Rancho Cordova General Plan and Municipal Code noise level standards at the closest existing noise-sensitive uses, noise impacts associated with construction activities are identified as being potentially significant.
Mitigation Impact 4:
In order to comply with applicable Rancho Cordova Municipal Code noise level standards, and in order to reduce to potential for an exceedance of applicable Rancho Cordova General Plan noise level criteria, the following measures should be incorporated into project construction operations:
MM 4: To the maximum extent practical, the following measures should be incorporated into the project construction operations:
Noise-generating construction activities shall occur within the hours and days identified in Section 6.68.090 of the Rancho Cordova Municipal Code and Policy N.1.4 of the Rancho Cordova General Plan.
Project construction operations shall comply with the construction related noise abatement measures contained Policies N.1.4, N.1.5, and N.1.7 of the Rancho Cordova General Plan.
All noise-producing project equipment and vehicles using internal-combustion engines shall be equipped with manufacturers-recommended mufflers and be maintained in good working condition.
All mobile or fixed noise-producing equipment used on the project site that are regulated for noise output by a federal, state, or local agency shall comply with such regulations while in the course of project activity. Electrically powered equipment shall be used instead of pneumatic or internalcombustion-powered equipment, where feasible. Material stockpiles and mobile equipment staging, parking, and maintenance areas shall be located as far as practicable from noise-sensitive uses. Project area and site access road speed limits shall be established and enforced during the construction period.

Nearby residences shall be notified of construction schedules so that arrangements can be made, if desired, to limit their exposure to short-term increases in ambient noise levels.
Significance of Impact 4 after Mitigation: Less than Significant Vibration Impacts Associated with Project Activities
Impact 5: Vibration Generated by Project Construction and On-Site Operations During project construction, heavy equipment would be used for grading, excavation, paving, and building construction, which would generate localized vibration in the immediate vicinity of the construction. The nearest existing sensitive structures (residences) are located approximately 30 feet from construction activities which would occur within the project site.
Table 16 includes the range of vibration levels for equipment commonly used in general construction projects at a distance of 25 feet. The Table 16 data also include predicted equipment vibration levels at the nearest existing residences to the project site located approximately 30 feet away.

2 Reference vibration level obtained from the Federal Transit Administration (FTA), Transit Noise and Vibration Impact Assessment Manual (2018).
As indicated in Table 16, vibration levels generated from on-site construction activities at the nearest existing residence located approximately 30 feet away are predicted to be well below the strictest Caltrans thresholds for damage to residential structures of 0.30 in/sec PPV shown in Table 6. Further, the predicted vibration levels in Table 16 are well below the threshold for a severe human response as defined by Caltrans in Table 7. Therefore, on-site construction within the project area is not expected to result in excessive groundborne vibration levels at nearby existing residential uses.
Results from the ambient vibration level monitoring at the project site (Table 4) indicate that measured average vibration levels were well below the strictest Caltrans thresholds for damage ITEM 11.1. ATTACHMENT 4

to structures and thresholds for annoyance. Therefore, it is expected that the project would not result in the exposure of persons to excessive groundborne vibration levels at proposed uses of the project.
The project proposes residential and park uses within the development. It is the experience of BAC that residential and park uses do not typically have equipment that generates appreciable vibration. Further, it is our understanding that the residential and park components of the project do not propose equipment that will produce appreciable vibration.
Because vibration levels due to and upon the proposed project are expected to satisfy the applicable Caltrans groundborne impact vibration criteria, this impact is considered to be less than significant.
Noise Impacts Upon the Development
The California Supreme Court issued an opinion in California Building Industry Association v. Bay Area Air Quality Management District (2015) holding that CEQA is primarily concerned with the impacts of a project on the environment and generally does not require agencies to analyze the impact of existing conditions on a project’s future users or residents. Nevertheless, the City of Rancho Cordova has policies that address existing/future conditions affecting the proposed project, which are discussed in the following section.
On-Site Traffic Noise Impacts
Impact 6: Future Exterior Traffic Noise Levels at Proposed Uses The FHWA Model was used with future traffic data to predict future exterior traffic noise levels at the proposed residential and park uses of the development. The future (Cumulative Plus Project) average daily traffic (ADT) volumes for Grant Line Road and Raymer Way were calculated using data provided in the project traffic impact analysis prepared by Kimley-Horn & Associates, Inc.
Specifically, future average daily traffic (ADT) volumes were conservatively estimated by applying a factor of 5 to the sum of AM and PM peak hour conditions. The predicted future Grant Line Road and Raymer Way traffic noise levels at the nearest proposed residential and park uses to the roadways are summarized in Table 17. Detailed FHWA Model inputs and results are provided in Appendix G.

As indicated in Table 17, predicted future combined Grant Line Road and Raymer Way traffic noise level exposure at the nearest proposed park use of the development (Park 1) would satisfy the applicable Ranch Cordova General Plan exterior noise level standard of 70 dB DNL for playgrounds and neighborhood park uses. However, at the nearest residential backyards, future combined traffic noise level exposure is predicted to exceed the General Plan exterior noise level standard of 60 dB DNL for residential uses. As a result, this impact is identified as being potentially significant.
Mitigation Impact 6:
In order to reduce future Grant Line Road and Raymer Way traffic noise level exposure to a state of compliance with the Rancho Cordova General Plan 60 dB DNL exterior noise level standard at the nearest backyards to the roadways, the following noise mitigation measure should be implemented:
MM 6: Solid traffic noise barriers measuring a minimum of 6-feet in height (relative to backyard elevation) should be constructed at the locations illustrated on Figure 2.
The traffic noise barriers could take the form of masonry wall, earthen berm, or a combination of the two. Other materials may be acceptable but should be reviewed by an acoustical consultant prior to use.
Table 18 shows the predicted mitigated future combined Grant Line Road and Raymer Way traffic noise levels at the nearest backyards to the roadways. As ITEM 11.1. ATTACHMENT 4

shown in Table 18, mitigated future combined traffic noise level exposure is predicted to satisfy the applicable Rancho Cordova General Plan 60 dB DNL exterior noise level standard at the backyards proposed nearest to the roadways.

Significance of Impact 6 after Mitigation: Less than Significant Impact 7: Future Interior Traffic Noise Levels at Proposed Residential Uses After implementation of Mitigation Measure 6 (construction of 6-foot-tall traffic noise barriers), future combined exterior traffic noise levels from Grant Line Road and Raymer Way are predicted to be approximately 58 dB DNL at the first-floor facades of the residences constructed nearest to the roadways. Due to reduced ground absorption at elevated positions and lack of shielding by the noise barriers identified in Mitigation Measure 6, future combined traffic noise levels at the upper-floor facades of those residences are predicted to be approximately 65 dB DNL. In order to satisfy the Rancho Cordova General Plan 45 dB DNL interior noise level standard, minimum noise reductions of 13 dB and 20 dB would be required of the first- and upper-floor building facades (respectively) of the residences constructed adjacent to the roadway.
Standard building construction (stucco siding, STC-27 windows, door weather-stripping, exterior wall insulation, composition plywood roof), typically results in an exterior to interior noise reduction of approximately 25 dB with windows closed and approximately 15 dB with windows open. This level of noise reduction would be adequate to reduce future Grant Line Road and Raymer Way traffic noise levels within all residences in this development to 45 dB DNL or less. As a result, no consideration of additional building facade construction improvements would be required for residences of the proposed development provided mechanical ventilation (air conditioning) is included to allow occupants to close doors and windows as desired for additional acoustical isolation. As a result, this impact is considered to be less than significant.
Impact 8: Public Park Noise at Proposed Residential Uses According to the project site plan illustrated on Figure 2, public parks are proposed to be located adjacent to residential uses at the north end of the development. Public park activities have been identified as a primary noise source that could impact nearby residential uses proposed within the development.
As noted previously, the Rancho Cordova General Plan Noise Element states that activities conducted on public parks are generally considered to be exempt from the noise standards ITEM 11.1. ATTACHMENT 4

established in the City’s Municipal Code (Noise Ordinance). Because noise associated with parks is not exempted by the Rancho Cordova General Plan, project public park noise level exposure would be subject to General Plan noise criteria. Because park activities would likely consist of human speech (i.e., shouting and cheering during activities), noise associated with park activities would be subject to the General Plan’s more restrictive daytime and nighttime hourly average noise level standards of 50 and 40 dB Leq (respectively) shown in Table 8. However, it is reasonable to assume that public park hours would be restricted to daytime hours only (7:00 a.m. to 10:00 p.m.). Based on the above information, project park noise exposure at the nearest proposed uses was assessed relative to the Rancho Cordova General Plan daytime hourly average noise level standard of 50 dB Leq.
An analysis of predicted public park noise exposure at existing noise-sensitive uses (residential uses) was presented in Impact 3. BAC file data referenced in that analysis indicate that parks consisting of active uses have noise levels of up to 50 dB Leq and 70 dB Lmax at a distance of 100 feet. The nearest proposed residential uses to a public park maintain a separation of approximately 70 feet from the center of the park. Based on the reference noise level presented above, and assuming standard spherical spreading loss (-6 dB per doubling of distance), park activity noise exposure at the nearest proposed residential uses located 70 feet away was calculated to be 53 dB Leq. The predicted park activity noise level of 53 dB Leq at the nearest residential uses would exceed the applicable Rancho Cordova General Plan daytime hourly average noise level standard of 50 dB Leq. As a result, this impact is identified as being potentially significant.
Mitigation Impact 8:
In order to reduce to reduce the potential for an exceedance of the Rancho Cordova General Plan daytime hourly average noise level standard of 50 dB Leq at adjacent proposed residential uses, the following public park noise mitigation measure should be implemented:
MM 8: Solid noise barriers measuring a minimum of 6-feet in height (relative to backyard elevation) should be constructed at the locations illustrated on Figure 2. The recommended noise barrier extension could take the form of a solid masonry wall or wood fence. Should the construction of a wood fence be selected as a barrier, the fence slats should overlap by a minimum of two inches and be screwed to the framing rather than nailed. The purpose of the overlapping slats and using screws rather than nails is to ensure that prolonged exposure to the elements does not result in visible gaps through the slats which would result in reduced noise barrier effectiveness. The final barrier design should be reviewed by an acoustical consultant prior to installation.
The construction of 6-foot tall noise barriers at the locations illustrated on Figure 2 would reduce predicted park noise level levels to 48 dB Leq or less at the nearest residential uses, and would satisfy the Rancho Cordova General Plan hourly average daytime noise level standard of 50 dB Leq.

Acoustical Terminology
Acoustics The science of sound.
Ambient Noise The distinctive acoustical characteristics of a given space consisting of all noise sources audible at that location. In many cases, the term ambient is used to describe an existing or pre-project condition such as the setting in an environmental noise study.
Attenuation The reduction of an acoustic signal.
A-Weighting A frequency-response adjustment of a sound level meter that conditions the output signal to approximate human response.
Decibel or dB Fundamental unit of sound. A Bell is defined as the logarithm of the ratio of the sound pressure squared over the reference pressure squared. A Decibel is one-tenth of a Bell.
CNEL Community Noise Equivalent Level. Defined as the 24-hour average noise level with noise occurring during evening hours (7 - 10 p.m.) weighted by a factor of three and nighttime hours weighted by a factor of 10 prior to averaging.
Frequency The measure of the rapidity of alterations of a periodic signal, expressed in cycles per second or hertz.
IIC Impact Insulation Class (IIC): A single-number representation of a floor/ceiling partition’s impact generated noise insulation performance. The field-measured version of this number is the FIIC.
Ldn Day/Night Average Sound Level. Similar to CNEL but with no evening weighting.
Leq Equivalent or energy-averaged sound level.
Lmax The highest root-mean-square (RMS) sound level measured over a given period of time.
Loudness A subjective term for the sensation of the magnitude of sound.
Masking The amount (or the process) by which the threshold of audibility is for one sound is raised by the presence of another (masking) sound.
Noise Unwanted sound.
Peak Noise The level corresponding to the highest (not RMS) sound pressure measured over a given period of time. This term is often confused with the “Maximum” level, which is the highest RMS level.
RT60 The time it takes reverberant sound to decay by 60 dB once the source has been removed.
STC Sound Transmission Class (STC): A single-number representation of a partition’s noise insulation performance. This number is based on laboratory-measured, 16-band (1/3- octave) transmission loss (TL) data of the subject partition. The field-measured version of this number is the FSTC.

Subject: Changes in noise levels associated with the addition of six (6) units for the proposed Preserve Residential Development in Rancho Cordova, California.
Dear Rod,
Bollard Acoustical Consultants, Inc. (BAC) previously prepared a noise and vibration assessment for the Preserve Residential Development project in Rancho Cordova, California (dated September 3, 2020). On January 4, 2021, it was brought to the attention of BAC that the project had been revised to include six (6) additional units. According to the revised traffic impact analysis prepared by the project traffic consultant (Kimley-Horn & Associates, Inc.) dated November 4, 2020, the project proposes a total of approximately 434 single-family residential units. After a review of the revised traffic impact analysis, specifically the revised peak-hour turning movements contained in that report, it was determined that the changes in noise levels associated with the additional units would not be appreciable and would not change the conclusions presented in the noise and vibration assessment previously prepared by BAC. As a result, a revision to the noise and vibration study prepared by BAC dated September 3, 2020 would not be warranted.
Please contact me at (916) 663-0500 or [email protected] if you have any questions or require additional information.
Sincerely,
Bollard Acoustical Consultants, Inc.

ITEM 11.1. ATTACHMENT 4
Executive Summary
This report has been prepared to present onsite and offsite sewer conveyance facilities to gravity serve the study area as well as identifying off-site contributing areas and downstream impacted areas. It addresses the viability of sewering the project, as well as consistency with the existing interceptor and trunk sewer master plans.
The Preserve is a proposed single family development (See Exhibit D). The Preserve is in the eastern part of Sacramento County, approximately 4,500 feet north of the intersection of Douglas Road and Americanos Boulevard. (See Exhibit A).
The Preserve encompasses a total of 279± acres, of which 184 acres are designated to be open space. Based on land use, with a minimum of 6 equivalent single-family dwelling (ESD’s) per acre (RD-6), the remaining 95 acres will be 440 single family homes and approximately 20± acres of public park and open space. The project proposes two points of connection to the existing system and the 440.0 ESD’s have Peak Wet Weather Flows (PWWF) of 0.210 MGD and
0.155 MGD. The flows leave the site at Node WP/MH-1 and Node WP-6/MH-26A.
There are no upstream areas that will contribute flow to the project sewer shed.
The Preserve is part of the BR East Rancho Area 1 Trunk Shed area per the SFEMP and would receive ultimate service from the Aerojet Interceptor Section 2S.
There are no required pump stations or force mains. This project proposes a permanent shed shift of 75± acres of The Preserve to the BR East Rancho Area 2. The designated open space north of Morrison Creek (184 Ac) is not part of the proposed shift (See Attachment A). The offsite facilities that are required to develop The Preserve have been constructed with the North Douglas development.
ITEM 11.1. ATTACHMENT 4
Section 1: Introduction
This study has been prepared at a Subdivision Plan level. At this level, it serves as a design guide for the creation of the subsequent improvement plans.
The Preserve covers 279+ acres. The ground ranges in elevation from 205 feet on the west side to 245 feet above sea level on the east side. The 184 acres north of Morrison Creek are currently in the South Sacramento Habitat Conservation Plan (SSHCP) as a preserve. This property is currently in negotiation to be sold to the SSHCP. As open space, the area is not included in the flow calculations. The proposed open space areas will not be developed and will be set aside for conservation purposes only.
There are no offsite upstream areas that will contribute to the flows produced by The Preserve.
The flow created from the project will utilize the existing North Douglas subdivision sewer system.
The Preserve will ultimately be serviced by the Aerojet Interceptor.
ITEM 11.1. ATTACHMENT 4
Section 2: Design
This study has been prepared in accordance with the current master plans.
Assumptions
Future upstream areas will not be served through The Preserve. It is anticipated that undeveloped areas within the (BR East Rancho Area 1) will be served according to the SFEMP, and will not be served to the south, through The Preserve and North Douglas developments.
Per the approved North Douglas Sewer Study, there are 1390 acres and 8522 ESD’s at Node DR4 in Douglas Road, producing 5.442 MGD. This study proposes to increase Node DR-4 to 1462.5 acres and 8969.6 ESD’s producing 5.927 MGD. From Node DR-4, flows travel west in a 24” sewer pipe at a slope of 0.0021. A 24” sewer pipe at s= 0.0021 has a capacity of 6.697 MGD.
High ground water tables typically don’t exist in this area of Sacramento County.
Approach: Mater Plan Design Procedures
The following general procedures are used in the development of this Sewer Master Plan:
• Major sewer sheds defined.
• A detailed collection system established.
• Major sheds divided into sub-sheds in order to define the areas, which contribute flows to certain points (nodes) on the collection system.
• Equivalent Single-Family Dwellings (ESDs) should be determined by lot count or by using 6 Equivalent Single-Family Dwellings (ESDs/acre), whichever is greater The methodology for estimating sewage flows in collectors and trunk lines in the Plan area sewer system is defined in the Sacramento Area Sewer District Standards and Specifications dated March 2019. The primary design criteria used in our analysis are listed in Table 1 below.

ESD values used in Sewer Master Plans assumed a minimum plan density of 6 ESD’s per acre.
Regional San and SASD
Sanitary sewer service in the project area is provided by the Sacramento Regional County Sanitation District (Regional San) and the Sacramento Area Sewer District (SASD).
Regional San is responsible for the interceptor collection (sanitary sewers which are designed to carry flows in excess of 10 million gallons per day) and treatment of wastewater.
SASD is responsible for the local collection facilities (up to 1 MGD) and trunk sewers with capacity of 1 million to 10 million gallons per day.
Regional San and SASD own, operate and are responsible for the public collection, trunk and interceptor sewer systems throughout Sacramento County as well as the Regional Wastewater Treatment Plant located south of Freeport.

Section 3: Sewer Flow Information
Currently there are no existing sewer facilities within The Preserve. When the 75 acres develops, it will produce 440.0 ESD’s and have a combined Peak Wet Weather Flow (PWWF) of
0.365 mgd. These flows leave the site at nodes MH-1 and MH-26A, and enter the North Douglas development. We are reducing the Peak Wet Weather Flow (PWWF) at node 2623- EN01 and increasing the Peak Wet Weather Flow (PWWF) at node 2875-EN01. See the approved Sewer Master Study for North Douglas 1, dated March 2004, and prepared by Wood Rodgers, Inc. for reference.
ITEM 11.1. ATTACHMENT 4
Section 4: Sewer Alignments and Facilities
The most feasible way to serve this project is by gravity through the North Douglas development down to Douglas Road. This is a permanent shed shift. At this time, there are no other alternatives to sewer The Preserve.
ITEM 11.1. ATTACHMENT 4
Section 5: Conclusion
This study was prepared with the intent of providing support documentation for use in the development of The Preserve improvement plans. As configured, all of the project flows will sewer south through the North Douglas project, and eventually into the Aerojet Interceptor.
No offsite upstream sewer flows through The Preserve, thus this study has only accounted for flows originated onsite. This project’s 75 developable acres account for approximately 440.0 ESD’s and produces a combined Peak Wet Weather Flow of 0.365 MGD’s. The Preserve does not adversely affect the downstream system.
