He has also assisted in the development of a remedial program for the site. The project site consists of a dry-cleaning facility located within a commercial/retail center.

Dry-cleaning operations occurred at the facility since 1974 and resulted in chlorinated solvent impacts to soil and groundwater beneath the site. As a result, the RWQCB opened a Spills, Leaks, Investigations, and Cleanups (SLIC) case and the site was referred to the Alameda County Water District (ACWD) for lead agency oversight. A series of soil and groundwater investigations identified a source area beneath the drycleaner suite and an adjoining retail suite. ENGEO prepared a Corrective Action Plan (CAP) and coordinated the in-situ chemical oxidation program that consisted of injecting 35,000 gallons of potassium permanganate to the subsurface to oxidize chlorinated solvents. The project is currently in the post-remediation monitoring phase.

Stone Lock District Development - Consulting Services—West Sacramento, CA Project Engineer. Jeff prepared a pro forma analysis of infrastructure-related costs for a preliminary development concept of the property. The analysis included a cost estimate for all site improvements, grading, utilities, and non-structural facilities. Included in the analysis was an evaluation of the existing adjacent levee system. Jeff worked with other team members to provide ENGEO - Expect ExcellencePage 1649 of 2600

JEFFREY ADAMS, PHD, PE
a preliminary assessment of the existing levee condition and prepared a cost estimate for levee rehabilitation and reconstruction. The project consists of a proposed mixed-use redevelopment as part of a city revitalization plan.

Torian Parcels - Additional Phase II Environmental Site Assessment—Newark, CA Project Manager. Jeff served as Project Manager and Project Engineer. He provided comprehensive geotechnical and environmental evaluation. Several significant geotechnical and environmental conditions existed at the property, including compressible soils, liquefiable soils, and significant deposits of non-engineered fill and debris. Several areas of soil and groundwater environmental impact were present due to historic industrial use at and in the vicinity of the site. Jeff performed a financial analysis of several mitigation alternatives to identify the most cost effective remedial solution, one in which a single remedial program in several locations addressed both environmental and geotechnical impact. Additionally, Jeff worked closely with the environmental oversight agency to develop a work plan to assess potential environmental impact. In developing and implementing the work plan, Jeff was able to demonstrate that environmental impact at the property was not as extensive as previously believed. This allowed for an alteration of the proposed site plan to avoid areas of potential impact, saving significant projected redevelopment costs. The project consists of a residential redevelopment of a 40-acre property formerly used for industrial purposes. The project consists of a residential redevelopment of a 40-acre property formerly used for industrial purposes.

Los Banos Airport - Phase I ESA—Los Banos, CA
Project Engineer. Jeff provided a Phase I ESA, prepared a soil and groundwater characterization program, and developed a conceptual soil remediation work plan as part of a multi-phase development. The Los Banos Airport project measures approximately 112 acres in area.

Navlet’s Garden Center Concord - Phase I ESA—Concord, CA Project Manager. Jeff prepared a Phase I ESA for the site. Jeff was able to effectively navigate through the complex historic records and ownership legacy associated with the property. He prepared a report that satisfied the demands and deadline of both the ownership entity and the financial institutions associated with the property. The project consists of a Navlet’s Garden Center.

Mare Island, 3rd and Connelly Utility Corridor Environmental Services—Vallejo, CA Project Engineer. Jeff provided environmental consultation support. During excavation of the utility corridor, zones of impacted soil were identified and removed from an approximate 9,300-square-foot footprint area and depths from 5 to 10½ feet below existing grade. The project consisted of utility demolition and soil excavation activities required to prepare for construction of a 300-foot water and sewer utility corridor along Connelly Street between 3rd Street and Azuar Drive.

Florentina Craciun, LSA
From: Cem Atabek, Baseline Environmental Consulting
Subject: Peer Review of Phase I Environmental Site Assessment, Vista Cove Planned Development Project, Vallejo, California
Baseline Environmental Consulting (Baseline) has performed a peer review of the Phase I Environmental Site Assessment (ESA) prepared by ENGEO and dated April 26, 2022, for the approximately 29‐acre property identified by Assessor’s Parcel Numbers (APNs) 0079‐171‐170, 0079‐120‐100, and a portion of 0079‐220‐070 in Vallejo, California (Site). Baseline noted that the Vista Cove Planned Development Project (project) is located only on APNs 0079‐171‐170 and 0079‐120‐100 (project site) and does not include the southeastern portion of the Site evaluated in the Phase I ESA. Baseline’s peer review was performed to evaluate whether the Phase I ESA was prepared in accordance with the ASTM International1 Standard for Phase I ESAs and adequately evaluates the Site history, existing observable conditions, current Site use, and current and former uses of surrounding properties to identify the potential presence of Recognized Environmental Conditions (RECs) and other environmental concerns at the Site.

Compliance with ASTM Standard for Phase I ESA
Based on our review, we believe that the Phase I ESA was prepared in general accordance with ASTM E1527‐21, which is the most current ASTM Standard for Phase I ESAs. Assumptions, limitations, and deviations from ASTM Standards are presented on pages 9 to 11 of the Phase I ESA and include the description of data gaps which ENGEO indicated do not affect the conclusions as to the presence or lack of presence of RECs at the Site. Baseline concurs that the data gaps should not affect the conclusions as to the presence or lack of presence of RECs at the Site.

Identification of RECs and Other Environmental Concerns Based on our review, we believe that the Phase I ESA adequately evaluated the Site history, existing observable conditions, current Site use, and current and former uses of surrounding properties to identify the potential presence of RECs at the Site. Based on our review of the Phase I ESA, Baseline has not identified RECs or other environmental concerns at the project site.

MEMORANDUM
To: Adam Smith, Sancerra
From: Andrew D. Palffy, P.E., dk Engineering
Date: May 3, 2023, Revised November 17, 2023
Subject: Drainage Study for Vista Cove in Vallejo, California The existing property at the intersection of Wildflower Ave and Shady Lane in Vallejo, California is 20.13 acres and consists of an undeveloped grassy hillside. The proposed project covers the northern 11.78 acres of the 20.13 acre property, consisting of 51 single-family homes complete with roadways and sidewalk areas. Please refer to the Development Review, Minor Use, Small-Lot Subdivision and Tentative Map Package prepared by dk Engineering on May 3, 2023 for the existing conditions and proposed site plans.

To accommodate the City of Vallejo's requirements for stormwater detention, Contra Costa Clean Water Program's C.3 guidebook, City of Vallejo Appendix A: Local Exceptions and Additional Requirements, the City of Vallejo Final Hydromodification Management Plan and the Solano County Water Agency Hydrology Manual were referred to for the site design. Per the City of Vallejo Final Hydromodification Report, the project uses the HEC-HMS software to design on-site hydromodification controls that provide flow duration control. To run the HEC-HMS simulation for the site, the Solano County Water Agency Report Chapter 3 guidelines were used. As shown on the proposed project site plan, the project is proposed with 2 detention basins that have treatment-only bioretention at the basin base.

The existing site has 3 ridges which split the existing drainage direction (show in Attachment A). Ultimately, all the existing drainage is directed downhill to the Benicia State Park, where the stormwater runoff converges and is directed to the Carquinez Strait. For the HEC-HMS simulation, all three existing drainage areas used the Solano County Water Agency Hydrology Manual recommended initial losses for Open Fields with Minimal vegetation, a value of 0.2 inches.

The proposed developed project has 2 drainage areas (Attachment B) that converge at one outfall where the stormwater runoff is directed to a detention basin and then treated with bioretention. For the HEC-HMS simulation, the drainage areas use the weighted average of the Solano County Water Agency Hydrology Manual recommended initial losses for Paved Areas and Lawn Grass (see Table 1). The Average for DA 2A is 0.172 inches and for DA 28 is 0.183 inches. Proposed Basin 2A is 3.33 feet deep. Proposed Basin 28 is 5.5 feet deep. The privately-owned basins are sized to have a minimum of one (1) foot of freeboard in the 100-year storm event and utilize side slopes of 3: 1. Table 2 below summarizes the design flows for the 15 year and 100 year storm events. The project's storm water is directed to the detention basin via a storm drain pipe system as well as sheet flow over landscaped areas. The basins have an overflow inlet which has orifices sized to control the outfall flow rates. From the overflow inlet, the water runs through an 18" storm drain pipe to the east side of the property where it outfalls into the existing marshland area that is adjacent to the Benicia State Park. Please see attachment C for the existing drainage pathway.

Hydrology and basin sizing will be finalized during the final design phase of this project.

II. SETTING
II.A. Project Location and Description
The Vista Cove project site is located in the city of Vallejo, California at the intersection of Shady Lane and Wildflower Ave. The project plans to have 51 single family residential units with access roadways, bioretention areas and site landscaping. The site will have 51 lots and various sized landscaped parcels. The project’s zoning is mix of Housing Types/Medium Density which requires lots to have front, corner side and rear yards and maximum lot coverage of 60% of the lot. The project is not anticipated to be phased. The property is located adjacent to the Glen Cove subdivision that consists of single-family homes. A vicinity map is provided as a supplemental attachment to this report.

II.B. Existing Site Features and Conditions
The existing undeveloped property is 20.13 acres and currently sits as fully vegetative covered area that slopes downhill to the southeastern side of the property. The property ranges in elevation from 75 to 155. There are currently no impervious areas on the site. There are 2 existing hydrologic features on the site, identified as a riparian area and a freshwater marsh. No existing municipal storm drain features exist on the property. The existing drainage for the site sheet flows off the site toward the adjacent 780 highway to the northeast, the riparian area in the property, the freshwater marsh in the property and off site to the adjacent City owned parcel to the southeast of the property. The existing soil type on the site includes lean clay with sand and sandstone and siltstone, the hydrologic soil group is category D and ground water was not encountered when borings were performed.

II.C. Opportunities for Stormwater Control
This site utilities 100% LID treatment via bioretention areas. The existing site drains to the southeastern boundary of the site. The natural direction of the flow is maintained to allow for prime bioretention space opportunities. The large difference in elevation for the site encourages the stormwater to flow via gravity to these bioretention areas and be treated prior to out falling to the existing water way location.

III. LOW IMPACT DEVELOPMENT DESIGN STRATEGIES
III.A. Optimization of Site Layout
III.A.1. Limitation of development envelope
The developable area consists of 11.78 acres of the property boundary. Parcel A is not a part of the project. The existing riparian area is to be avoided.

III.A.2. Preservation of natural drainage features
The riparian area in the middle of the developed area is preserved on the site as an enhanced feature of the site.

III.A.3. Setbacks from creeks, wetlands, and riparian habitats The riparian limits clarified by the project biologists are accounted for in the site plan.

III.A.4. Minimization of imperviousness
Project pathways are designed to minimum widths but offer a walkable environment and landscaped areas are provided in lieu of potential impervious beautification features.

III.A.5. Use of drainage as a design element
Bioretention facilities are incorporated into the site as a design element to the site landscaping.

Vista Cove Page 3 of 5 November 2023
III.B. Use of Permeable Pavements
Permeable pavement material is not used at the site. The bioretention features meet the treatment sizing requirements for stormwater control.

III.C. Dispersal of Runoff to Pervious Areas
Where feasible, drainage from impervious areas is directed to pervious spaces. Ultimately, drainage from the site is all directed to pervious bioretention areas that are placed throughout the site.

III.D. Bioretention or other Integrated Management Practices Bioretention areas have been designed per the IMP sizing calculator requirements. The site is graded to drain to low points, which is where the bioretention spaces are located throughout the site.

IV.A.2. Drainage Management Area Descriptions
DMA 1, totaling 59,945 square feet, drains towards the northwest corner of the property. DMA 1, with 27,427 sf impervious area and 32,518 sf pervious area, drains to IMP 1, a bioretention area that has a treatment area of 1,228 sf.

DMA 2, totaling 282,178 square feet, drains towards the northwest corner of the property. DMA 2, with 144,462 sf impervious area and 137,716 sf pervious area, drains to IMP 2, a bioretention area that has a treatment area of 6,390 sf.

Self-treating DMA, totaling 101,865 square feet, consists of pervious area and drains to adjacent pervious space at the northeastern side of the property and the southeastern side of the property.

IV.B. Integrated Management Practice Descriptions
The bioretention areas are designed for treatment only. Flow control measures are incorporated via detention basins that sit above the bioretention area. The base rock layer of the bioretention is 12” deep. The overflow structure is also set at 1’ below freeboard of the 100-year storm event. to allow for ponding prior to being treated and then traveling directly into the storm drain system. The facilities are sized per the Contra Costa IMP calculator and the results are included on the Stormwater Control Plan attached. Refer to the separate drainage study memo prepared by dk Engineering, Revised November 2023 for discussion on the hydromodification element of the proposed basins.

Be designed to minimize irrigation
and runoff and to minimize use of
fertilizers and pesticides that can
contribute to stormwater pollution.

Specific plantings within
bioretention areas and swales that
are tolerant of the sandy loam soil
and periodic inundation.

Include pest-resistant plants.

Include plantings appropriate to
site soils, slopes, climate, sun,
wind, rain, land use, air movement,
ecological consistency, and plant
interactions.

Landscape will be maintained using
minimum or no pesticides.

IPM information will be provided to
property owners
Streets and Sidewalks Sweep streets and sidewalks to prevent accumulation of litter and debris.

Collect debris from pressure washing
to prevent entry into the storm drain
system. Collect wash water containing
any cleaning agent or degreaser and
discharge to the sanitary sewer, not to
the storm drain.

1 EXECUTIVE SUMMARY
Urban Crossroads, Inc. has prepared this noise study to identify noise impacts and any necessary noise mitigation measures for the Vista Cove development (“Project”) located at Shady Lane and Wildflower Road (APN’s 0037-030-200, 0037-030-210, 0037-060-480), in the City of Vallejo. The proposed Project would subdivide 20.13 acres and develop 51 single-family detached homes on approximately 10 acres, with the remaining area being open space. This study has been prepared to satisfy the applicable City of Vallejo standards and thresholds of significance based on Appendix G of the California Environmental Quality Act (CEQA) Guidelines. (1)

EXTERIOR NOISE ABATEMENT
To satisfy the City of Vallejo exterior noise level standard of 60 dBA Ldn for single-family residential land uses, the construction of a noise barrier is recommended for the outdoor living area (backyards) of Lots 8 and 16, adjacent to Interstate 780 (I-780). With the recommended noise barriers shown in Exhibit ES-A, the future exterior noise levels will range from 26.9 to 59.5 dBA CNEL. This noise analysis shows that the recommended noise barrier will satisfy the City of Vallejo 60 dBA Ldn exterior noise level standards for single-residential land uses. The effective noise barrier height recommendations represent the minimum wall and/or berm combination height required to satisfy the City of Vallejo exterior noise level standards.

The recommended noise control barriers shall be constructed so that the top of each wall and /or berm combination extends to the planned height above the pad elevation of the lot it is shielding. When the road is elevated above the pad elevation, the barrier shall extend to the recommended height above the highest point between the residential home and the road. The barrier shall provide a surface area weight of at least 4 pounds per square foot with no decorative cutouts or line-of-sight openings between shielded areas and the roadways or a minimum transmission loss of 20 dBA. (2) The noise barrier shall be constructed using the following materials:
 Masonry block;
 Stucco veneer over wood framing (or foam core), or 1-inch-thick tongue and groove wood of sufficient weight per square foot;
 Glass (1/4-inch-thick), or other transparent material with sufficient weight per square foot capable of providing a minimum transmission loss of 20 dBA;
 Earthen berm;
 Any combination of these construction materials.
 The barrier shall consist of a solid face from top to bottom. Unnecessary openings or decorative cutouts shall not be made. All gaps (except for weep holes) should be filled with grout or caulking.

3 INTERIOR NOISE ABATEMENT
Typical building construction will provide a Noise Reduction (NR) of approximately 12 dBA with "windows open" and a minimum 25 dBA noise reduction with "windows closed." (3) The interior noise level analysis shows that the City of Vallejo 45 dBA CNEL interior noise standard can be satisfied using standard windows and mechanical ventilation (e.g., air conditioning) being provided for all units. Since Project architectural plans are unavailable at this time, the Project should submit a final interior noise analysis to the building department during the final plan check.

OFF-SITE TRAFFIC NOISE
The expected Project is anticipated to generate approximately 510 trips per day. The location where the greatest chance of an impact occurs is at the residence near the Project site entrance and at Shady Lane and Wildflower Avenue. Without consideration of any barriers, the Project is predicted to generate a noise level of 50.2 dBA CNEL at the nearest building façade. Therefore, the Project would not expose existing noise-sensitive receivers to excessive noise levels, and the off-site traffic noise level impacts due to the Project are considered less than significant.

OPERATIONAL NOISE
The Project’s primary noise sources would be air conditioners. Project operational noise levels at off-site receiver locations are expected to range from 23.7 to 33.3 dBA Leq. Project operational noise levels will satisfy Section 16.502.09 of the City of Vallejo Municipal Code daytime and nighttime noise standards of 60 dBA and 50 dBA Leq, respectively, at all residential receivers.

Therefore, Project-related operational noise impacts would be less than significant.

CONSTRUCTION NOISE ANALYSIS
Construction noise levels are expected to create temporary and intermittent high noise levels at receivers surrounding the Project site when activities occur at the closest point to the nearby receiver locations from the edge of Project construction activity. Using reference noise levels to represent the construction activities at the Project site, this analysis estimates the Project-related construction noise levels at nearby sensitive receiver locations. The results of the analysis show the highest construction noise levels at the potentially impacted receiver locations are expected to approach 65.0 dBA Leq.

The Project related construction equipment noise levels are anticipated to satisfy the City of Vallejo Municipal Code construction noise level standards of 80 dBA for mobile equipment during typical Project construction activities at all receiver locations. Therefore, the short-term Project construction impacts are considered a less than significant.

CONSTRUCTION VIBRATION ANALYSIS
Construction activity can result in varying degrees of ground vibration, depending on the equipment and methods used, distance to the affected structures and soil type. It is expected that ground-borne vibration from Project construction activities would cause only intermittent,

Vista Cove Noise Impact Analysis
15304-07-Noise_Study.docx
4 localized intrusion. Project construction vibration velocity levels are expected to approach 0.07 in/sec PPV at the nearby receiver locations, and will therefore, not exceed the vibration threshold of 0.10 in/sec PPV. Therefore, construction related vibration impacts would be less than significant.

SUMMARY OF SIGNIFICANCE FINDINGS
The results of this Vista Cove Noise Impact Analysis are summarized below based on the significance criteria in Section 4 of this report. Table ES-1 shows the findings of significance for each potential noise and/or vibration impact before and after incorporation of Project design features.

9 2 FUNDAMENTALS
Noise has been simply defined as “unwanted sound.” Sound becomes unwanted when it interferes with normal activities, when it causes actual physical harm or when it has adverse effects on health. Noise is measured on a logarithmic scale of sound pressure level known as a decibel (dB). A-weighted decibels (dBA) approximate the subjective response of the human ear to broad frequency noise source by discriminating against very low and very high frequencies of the audible spectrum. They are adjusted to reflect only those frequencies which are audible to the human ear. Exhibit 2-A presents a summary of the typical noise levels and their subjective loudness and effects that are described in more detail below.

2.1 RANGE OF NOISE
Since the range of intensities that the human ear can detect is so large, the scale frequently used to measure intensity is a scale based on multiples of 10, the logarithmic scale. The scale for measuring intensity is the decibel scale. Each interval of 10 decibels indicates a sound energy ten times greater than before, which is perceived by the human ear as being roughly twice as loud. (4) The most common sounds vary between 40 dBA (very quiet) to 100 dBA (very loud). Normal conversation at three feet is roughly at 60 dBA, while loud jet engine noises equate to 110 dBA

10 at approximately 100 feet, which can cause serious discomfort. (5) Another important aspect of noise is the duration of the sound and the way it is described and distributed in time.

2.2 NOISE DESCRIPTORS
Environmental noise descriptors are generally based on averages, rather than instantaneous, noise levels. The most commonly used figure is the equivalent level (Leq). Equivalent sound levels are not measured directly but are calculated from sound pressure levels typically measured in Aweighted decibels (dBA). The equivalent sound level (Leq) represents a steady state sound level containing the same total energy as a time varying signal over a given sample period and is commonly used to describe the “average” noise levels within the environment.

To describe the time-varying character of environmental noise, the statistical or percentile noise descriptors L50, L25, L8 and L2, are commonly used. The percentile noise descriptors are the noise levels equaled or exceeded during 50 percent, 25 percent, 8 percent, and 2 percent of a stated time. Sound levels associated with the L2 and L8 typically describe transient or short-term events, while levels associated with the L50 describe the steady state (or median) noise conditions. While the L50 describes the median noise levels occurring 50 percent of the time, the Leq accounts for the total energy (average) observed for the entire hour. Therefore, the Leq noise descriptor is generally 1-2 dBA higher than the L50 noise level.

Peak hour or average noise levels, while useful, do not completely describe a given noise environment. Noise levels lower than peak hour may be disturbing if they occur during times when quiet is most desirable, namely evening and nighttime (sleeping) hours. To account for this, the Community Noise Equivalent Level (CNEL), representing a composite 24-hour noise level is utilized. The CNEL is the weighted average of the intensity of a sound, with corrections for time of day, and averaged over 24 hours. The time-of-day corrections require the addition of 5 decibels to dBA Leq sound levels in the evening from 7:00 p.m. to 10:00 p.m., and the addition of 10 decibels to dBA Leq sound levels at night between 10:00 p.m. and 7:00 a.m. These additions are made to account for the noise sensitive time periods during the evening and night hours when sound appears louder. CNEL does not represent the actual sound level heard at any time, but rather represents the total sound exposure. The City of Vallejo relies on the 24-hour CNEL level to assess land use compatibility with transportation related noise sources.

2.3 SOUND PROPAGATION
When sound propagates over a distance, it changes in level and frequency content. The way noise reduces with distance depends on the following factors.

Vista Cove Noise Impact Analysis
15304-07-Noise_Study.docx
11 2.3.1 GEOMETRIC SPREADING
Sound from a localized source (i.e., a stationary point source) propagates uniformly outward in a spherical pattern. The sound level attenuates (or decreases) at a rate of 6 dB for each doubling of distance from a point source. Highways consist of several localized noise sources on a defined path and hence can be treated as a line source, which approximates the effect of several point sources. Noise from a line source propagates outward in a cylindrical pattern, often referred to as cylindrical spreading. Sound levels attenuate at a rate of 3 dB for each doubling of distance from a line source. (4)

2.3.2 GROUND ABSORPTION
The propagation path of noise from a highway to a receptor is usually very close to the ground.

Noise attenuation from ground absorption and reflective wave canceling adds to the attenuation associated with geometric spreading. Traditionally, the excess attenuation has also been expressed in terms of attenuation per doubling of distance. This approximation is usually sufficiently accurate for distances of less than 200 ft. For acoustically hard sites (i.e., sites with a reflective surface between the source and the receptor, such as a parking lot or body of water), no excess ground attenuation is assumed. For acoustically absorptive or soft sites (i.e., those sites with an absorptive ground surface between the source and the receptor such as soft dirt, grass, or scattered bushes and trees), an excess ground attenuation value of 1.5 dB per doubling of distance is normally assumed. When added to the cylindrical spreading, the excess ground attenuation results in an overall drop-off rate of 4.5 dB per doubling of distance from a line source. (6)

2.3.3 ATMOSPHERIC EFFECTS
Receptors located downwind from a source can be exposed to increased noise levels relative to calm conditions, whereas locations upwind can have lowered noise levels. Sound levels can be increased at large distances (e.g., more than 500 feet) due to atmospheric temperature inversion (i.e., increasing temperature with elevation). Other factors such as air temperature, humidity, and turbulence can also have significant effects. (4)

2.3.4 SHIELDING
A large object or barrier in the path between a noise source and a receptor can substantially attenuate noise levels at the receptor. The amount of attenuation provided by shielding depends on the size of the object and the frequency content of the noise source. Shielding by trees and other such vegetation typically only has an “out of sight, out of mind” effect. That is, the perception of noise impact tends to decrease when vegetation blocks the line-of-sight to nearby resident. However, for vegetation to provide a substantial, or even noticeable, noise reduction, the vegetation area must be at least 15 feet in height, 100 feet wide and dense enough to completely obstruct the line-of sight between the source and the receiver. This size of vegetation may provide up to 5 dBA of noise reduction. The FHWA does not consider the planting of vegetation to be a noise abatement measure. (6)

Vista Cove Noise Impact Analysis
15304-07-Noise_Study.docx
12 2.4 NOISE CONTROL
Noise control is the process of obtaining an acceptable noise environment for an observation point or receptor by controlling the noise source, transmission path, receptor, or all three. This concept is known as the source-path-receptor concept. In general, noise control measures can be applied to these three elements.

2.5 NOISE BARRIER ATTENUATION
Effective noise barriers can reduce noise levels by 10 to 15 dBA, cutting the loudness of traffic noise in half. A noise barrier is most effective when placed close to the noise source or receptor.

Noise barriers, however, do have limitations. For a noise barrier to work, it must be high enough and long enough to block the path of the noise source. (6)

2.6 LAND USE COMPATIBILITY WITH NOISE
Some land uses are more tolerant of noise than others. For example, schools, hospitals, churches, and residences are more sensitive to noise intrusion than are commercial or industrial developments and related activities. As ambient noise levels affect the perceived amenity or livability of a development, so too can the mismanagement of noise impacts impair the economic health and growth potential of a community by reducing the area’s desirability as a place to live, shop and work. For this reason, land use compatibility with the noise environment is an important consideration in the planning and design process. The FHWA encourages State and Local government to regulate land development in such a way that noise-sensitive land uses are either prohibited from being located adjacent to a highway, or that the developments are planned, designed, and constructed in such a way that noise impacts are minimized. (7)

2.7 VIBRATION
Per the Federal Transit Administration (FTA) Transit Noise and Vibration Impact Assessment Manual (8), vibration is the periodic oscillation of a medium or object. The rumbling sound caused by the vibration of room surfaces is called structure-borne noise. Sources of groundborne vibrations include natural phenomena (e.g., earthquakes, volcanic eruptions, sea waves, landslides) or human-made causes (e.g., explosions, machinery, traffic, trains, construction equipment). Vibration sources may be continuous, such as factory machinery, or transient, such as explosions. As is the case with airborne sound, ground-borne vibrations may be described by amplitude and frequency.

Additionally, in contrast to airborne noise, ground-borne vibration outdoors is not a common environmental problem and annoyance from ground-borne vibration is almost exclusively an indoor phenomenon (9). Therefore, the effects of vibrations should only be evaluated at a structure and the effects of the building structure on the vibration should be considered. Woodframe buildings, such as typical residential structures, are more easily excited by ground vibration than heavier buildings. In contrast, large masonry buildings with spread footings have a low response to ground vibration (9). In general, the heavier a building is, the lower the response will

Vista Cove Noise Impact Analysis
15304-07-Noise_Study.docx
13 be to the incident vibration energy. However, all structurers reduce vibration levels due to the coupling of the building to the soil.

There are several different methods that are used to quantify vibration. The peak particle velocity (PPV) is defined as the maximum instantaneous peak of the vibration signal (9). The PPV is most frequently used to describe vibration impacts to buildings but is not always suitable for evaluating human response (annoyance) because it takes some time for the human body to respond to vibration signals. Instead, the human body responds to average vibration amplitude often described as the root mean square (RMS). The RMS amplitude is defined as the average of the squared amplitude of the signal and is most frequently used to describe the effect of vibration on the human body (9). However, the RMS amplitude and PPV are related mathematically, and the RMS amplitude of equipment is typically calculated from the PPV reference level. The RMS amplitude is approximately 70% of the PPV (10). Thus, thus either can be used on the description of vibration impacts.

While not universally accepted, vibration decibel notation (VdB) is another vibration notation developed and used by the FTA in their guidance manual to describe vibration levels and provide a background of common vibration levels and set vibration limits (8). Decibel notation (VdB) serves to reduce the range of numbers used to describe vibration levels and is used in this report to describe vibration levels.

As stated in the FTA guidance manual, the background vibration-velocity level in residential areas is generally 50 VdB. Ground-borne vibration is normally perceptible to humans at approximately 65 VdB. For most people, a vibration-velocity level of 75 VdB is the approximate dividing line between barely perceptible and distinctly perceptible levels (9). Typical outdoor sources of perceptible ground-borne vibration are construction equipment, steel-wheeled trains, and traffic on rough roads. If a roadway is smooth, the ground-borne vibration is rarely perceptible. The range of interest is from approximately 50 VdB, which is the typical background vibration-velocity level, to 100 VdB, which is the general threshold where minor damage can occur in fragile buildings. Exhibit 2-B illustrates common vibration sources and the human and structural response to ground-borne vibration.

15 3 REGULATORY SETTING
To limit population exposure to physically and/or psychologically damaging as well as intrusive noise levels, the federal government, the State of California, various county governments, and most municipalities in the state have established standards and ordinances to control noise. In most areas, automobile and truck traffic is the major source of environmental noise. Traffic activity generally produces an average sound level that remains constant with time. Air and rail traffic, and commercial and industrial activities are also major sources of noise in some areas.

Federal, state, and local agencies regulate different aspects of environmental noise. Federal and state agencies generally set noise standards for mobile sources such as aircraft and motor vehicles, while regulation of stationary sources is left to local agencies.

3.1 STATE OF CALIFORNIA NOISE REQUIREMENTS
The State of California regulates freeway noise, sets standards for sound transmission, provides occupational noise control criteria, identifies noise standards and provides guidance for local land use compatibility. State law requires that each county and city adopt a General Plan that includes a Noise Element, which is to be prepared according to guidelines adopted by the Governor’s Office of Planning and Research. (11) The purpose of the Noise Element is to limit the exposure of the community to excessive noise levels. In addition, the California Environmental Quality Act (CEQA) requires that all known environmental effects of a project be analyzed, including environmental noise impacts.

3.2 STATE OF CALIFORNIA BUILDING CODE
The State of California’s noise insulation standards for dwelling and sleeping units are codified in the California Code of Regulations, Title 24, Building Standards Administrative Code, Chapter 12, Section 1206 Sound Control. These noise standards are applied to new construction in California for controlling interior noise levels resulting from exterior noise sources within habitable rooms of dwelling and sleeping units. For new construction, the acceptable interior noise limit is 45 dBA CNEL in habitable rooms (12).

3.3 CITY OF VALLEJO GENERAL PLAN NOISE STANDARDS
The City of Vallejo has adopted a noise standards specifying land use compatibility standards in the Nature & Built Environment Chapter of the General Plan to limit exposure to noise and to minimize adverse effects on sensitive receptors like homes and schools. (13) The General Plan specifies the exterior noise levels, described in Ldn, allowable for new developments impacted by transportation noise sources such as arterial roads, freeways, airports and railroads. (13) To ensure compatible noise levels at noise sensitive receivers the City of Vallejo General Plan contains the following policies and actions related to the Project:

POLICY NBE-5.13 Noise Control. Ensure that noise does not affect quality of life in the community.

Action NBE-5.13C Update City regulations to restrict the allowable hours to between 7 AM and 7 PM on weekdays for construction, demolition, maintenance, and loading/unloading activities that may impact noise-sensitive land uses.

Vista Cove Noise Impact Analysis
15304-07-Noise_Study.docx
16 POLICY NBE-5.14 Vibration Control. Ensure that vibration does not affect quality of life in the community.

Action NBE-5.14A Update City regulations to establish quantified vibration level limits similar to commonly used guidelines found in the Federal Transit Administration document “Transit Noise and Vibration Impact Assessment” (2006) POLICY NBE-5.15 Noise Compatibility Standards. Apply the General Plan noise and land use compatibility standards to all new residential, commercial, and mixed-use development and redevelopment
Action NBE-5.15A For new single-family residential projects, use a standard of 60 Ldn for exterior noise in private use areas, and require appropriate impact mitigation.

Action NBE-5.15D Require maximum interior noise levels at 45 Ldn in all new residential units, and require appropriate impact mitigation
Action NBE-5.15E When approving new development, limit project-related noise increases to the following for permanent stationary and transportation-related noise sources:
•no more than 10 dB in non-residential areas;
•no more than 5 dB in residential areas where the with-project noise level is less than the maximum "normally acceptable" level in the Noise and Land Use Compatibility figure; and •no more than 3 dB where the with-project noise level exceeds the "normally acceptable" level in Noise and Land Use
Compatibility figure.

Action NBE-5.15F Require acoustical studies with appropriate mitigation measures for projects that are likely to be exposed to noise levels that exceed the ‘normally acceptable’ standard and for any other projects that are likely to generate noise in excess of these standards.

The noise policies consider land use compatibility and identify exterior noise level compatibility standards for transportation related noise. Table NBE-1 of the City of Vallejo General Plan, California Land Use Compatibility for Community Noise Environments matrix shown on Exhibit 3- A, provides the City of Vallejo with a planning tool to gauge the compatibility of new sensitive land uses relative to existing and future exterior noise levels. To limit exposure to noise and to minimize adverse effects on sensitive receptors (Policy NBE.515), Table NBE-1 identifies a 60 dBA CNEL as a normally acceptable and 70 dBA CNEL as conditionally acceptable noise levels for single-family residential land uses impacted by transportation noise sources. According to Table NBE-1, noise levels in excess of normally acceptable levels require that a detailed analysis of the noise reduction requirements must be made and needed noise-insulation features must be included in the design.

18 Vallejo to determine the potential noise impacts at the nearby sensitive receiver locations. The operational-related noise standards are summarized in Exhibit 3-B and Exhibit 3-C shows the maximum noise level adjustments by time and type.

The City of Vallejo has established maximum exterior and interior noise levels for Project operational noise sources. Section 16.502.09(C)(2) of the Municipal Code identifies limits on noise levels from operational activities as shown on Exhibits 3-C. The nearest noise-sensitive receivers to the Project site consist of existing single-family residential homes. For single-family residential development, operational exterior noise levels may not exceed 60 dBA during the daytime hours (7:00 a.m. to 10:00 p.m.). (14) The standard limits in Exhibit-B shall be adjusted by 5 decibels for any noise that contains a steady, pure tone such as a whine, screech or hum, or an impulsive sound such as hammering or riveting, or contains music or speech. The City of Vallejo Municipal Code is included in Appendix 3.1.

19 the City of Vallejo to determine the potential noise impacts at the nearby sensitive receiver locations. The construction-related noise standards are summarized in Exhibit 3-D.

The City of Vallejo has established maximum noise levels for mobile and stationary construction equipment. Table 16.502-E of Section 16.502, Performance Standards, of the Municipal Code identifies limits on noise levels from construction activities as shown on Exhibits 3-C for mobile and stationary equipment. The nearest noise-sensitive receivers to the Project site consist of existing single-family residential homes. For single-family residential development, mobile equipment noise levels may not exceed 80 dBA and stationary equipment noise levels may not exceed 65 dBA during the daytime hours. (14) In addition, the Municipal Code identifies hours during which mobile and stationary equipment may operate, between 7:00 a.m. to 6:00 p.m. weekdays, between 9:00 a.m. to 6:00 p.m. Saturdays, and no activity allowed on Sundays or holidays (City of Vallejo Municipal Code, Section 16.502.099(D)(1).

20 vibration is generally associated with pile driving and rock blasting. Other construction equipment, such as air compressors, light trucks, hydraulic loaders, etc., generates little or no ground vibration. (9)
To analyze vibration impacts originating from the operation and construction of the Vista Cove, vibration-generating activities are appropriately evaluated against standards established under a City’s Municipal Code, if such standards exist. However, City of Vallejo General Plan noise policy NBE-5.14 and Section 16.502.08, Vibration, of the Municipal Code do not identify specific vibration level limits. Therefore, for analysis purposes, the Caltrans Transportation and Construction Vibration Guidance Manual, (10 p. 38) Tables 19 and 20 are used in this noise study to assess potential temporary construction-related impacts at adjacent building locations. The construction vibration damage potential criteria include consideration of the building conditions. (5 p. 182) The existing buildings adjacent to the Project site can best be described as “older residential structures” with a maximum acceptable continuous vibration threshold of 0.3 PPV (in/sec). The construction vibration annoyance potential criteria include consideration of the perception of vibration, which indicates a maximum acceptable continuous vibration threshold of 0.1 PPV (in/sec) would be considered strongly perceptible. While vibration impacts are only assessed within structures and temporary annoyance is not generally considered a substantial effect on the environment, for purposes of this analysis, the more conservative 0.1 PPV (in/sec) threshold is used to evaluate potential construction vibration impacts at nearby receivers.

Vista Cove Noise Impact Analysis
15304-07-Noise_Study.docx
21 4 SIGNIFICANCE CRITERIA
The following significance criteria are based on currently adopted guidance provided by Appendix G of the California Environmental Quality Act (CEQA) Guidelines. (15) For the purposes of this report, impacts would be potentially significant if the Project results in or causes:

A. Generation of a substantial temporary or permanent increase in ambient noise levels in the vicinity of the project in excess of standards established in the local general plan or noise ordinance, or applicable standards of other agencies?
B. Generation of excessive ground-borne vibration or ground-borne noise levels? C. For a project located within the vicinity of a private airstrip or an airport land use plan or, where such a plan has not been adopted, within two miles of a public airport or public use airport, would the project expose people residing or working in the project area to excessive noise levels? While the City of Vallejo General Plan Guidelines provide direction on noise compatibility and establish noise standards by land use type that are sufficient to assess the significance of noise impacts, they do not define the levels at which increases are considered substantial for use under Guideline A. CEQA Appendix G Guideline C applies to nearby public and private airports, if any, and the Project’s land use compatibility. Table 4-1 shows the significance criteria summary matrix.

4.1 CEQAGUIDELINES NOT FURTHER ANALYZED
The Project site is not located within two miles of an airport or airstrip. The closest major airport is the Buchanan Field Airport and Napa County Airport are located roughly 9.6 miles southeast and northwest, respectively, of the Project site. As such, the Project site would be located outside the 55 dBA CNEL airport noise contour for both airports, and therefore, impacts are considered less than significant, and no further noise analysis is conducted in relation to Appendix G to the CEQA Guidelines, Noise Threshold C.

4.2 NOISE-SENSITIVE RECEIVERS
Noise level increases resulting from the Project are evaluated based on the Appendix G CEQA Guidelines described above at the closest sensitive receiver locations. Under CEQA, consideration must be given to the magnitude of the increase, the existing ambient noise levels, and the location of noise-sensitive receivers to determine if a noise increase represents a significant adverse environmental impact. This approach recognizes that there is no single noise increase that renders the noise impact significant. (16) Unfortunately, there is no completely satisfactory way to measure the subjective effects of noise or of the corresponding human reactions of annoyance and dissatisfaction. This is primarily because of the wide variation in individual thresholds of annoyance and differing individual experiences with noise. Thus, an important way of determining a person’s subjective reaction to a new noise is the comparison of it to the existing environment to which one has adapted—the so-called ambient environment. In general, the more a new noise exceeds the previously existing

Vista Cove Noise Impact Analysis
15304-07-Noise_Study.docx
22 ambient noise level, the less acceptable the new noise will typically be judged. The Federal Interagency Committee on Noise (FICON) (17) developed guidance to be used for the assessment of project-generated increases in noise levels that consider the ambient noise level. The FICON recommendations are based on studies that relate aircraft noise levels to the percentage of persons highly annoyed by aircraft noise. Although the FICON recommendations were specifically developed to assess aircraft noise impacts, these recommendations are often used in environmental noise impact assessments involving the use of cumulative noise exposure metrics, such as the average-daily noise level (CNEL) and equivalent continuous noise level (Leq).

As previously stated, the approach used in this noise study recognizes that there is no single noise increase that renders the noise impact significant, based on a 2008 California Court of Appeal ruling on Gray v. County of Madera. (16) For example, if the ambient noise environment is quiet (<60 dBA) and the new noise source greatly increases the noise levels, an impact may occur if the noise criteria may be exceeded. Therefore, for this analysis, FICON identifies a readily perceptible 5 dBA or greater project-related noise level increase is considered a significant impact when the noise criteria for a given land use is exceeded. Per the FICON, in areas where the without project noise levels range from 60 to 65 dBA, a 3 dBA barely perceptible noise level increase appears to be appropriate for most people. When the without project noise levels already exceed 65 dBA, any increase in community noise louder than 1.5 dBA or greater is considered a significant impact if the noise criteria for a given land use is exceeded, since it likely contributes to an existing noise exposure exceedance.

The FICON guidance provides an established source of criteria to assess the impacts of substantial temporary or permanent increase in ambient noise levels. Based on the FICON criteria, the amount to which a given noise level increase is considered acceptable is reduced when the without Project noise levels are already shown to exceed certain land-use specific exterior noise level criteria. The specific levels are based on typical responses to noise level increases of 5 dBA or readily perceptible, 3 dBA or barely perceptible, and 1.5 dBA depending on the underlying without Project noise levels for noise-sensitive uses. These levels of increases and their perceived acceptance are consistent with guidance provided by both the Federal Highway Administration (18 p. 9) and Caltrans (19 p. 2_48).

4.3 SIGNIFICANCE CRITERIA SUMMARY
Noise impacts shall be considered significant if any of the following occur as a direct result of the proposed Project. Table 4-1 shows the significance criteria summary matrix.

25 5 EXISTING ON-SITE NOISE LEVELS
To assess the existing noise level environment, noise levels are referenced from the Propel Vallejo General Plan 2040 and Sonoma Boulevard Specific Plan Draft EIR. (20) Based on Figure 4.10-1, the Project lies within the 70 dBA CNEL traffic noise contour of I-780. In addition, Table 4.10-13 shows that the freeway segment from Columbus Parkway to Glen Cove Parkway exposes adjacent land uses to 77.7 dBA CNEL at 100 feet from the centerline. However, these noise levels are likely over-exaggerated since they are intended to be used for planning and generally do not consider the actual topography. The background ambient noise levels in the Project study area are considered to be dominated by the transportation-related noise associated with I-780.

27 6 TRAFFIC NOISE METHODS AND PROCEDURES
The following section outlines the methods and procedures used to model and analyze the future traffic noise environment.

6.1 FHWA TRAFFIC NOISE PREDICTION MODEL
The estimated roadway noise impacts from vehicular traffic were calculated using a computer program that replicates the Federal Highway Administration (FHWA) Traffic Noise Prediction Model- FHWA-RD-77-108. (21) The FHWA Model arrives at a predicted noise level through a series of adjustments to the Reference Energy Mean Emission Level (REMEL). In California the national REMELs are substituted with the California Vehicle Noise (Calveno) Emission Levels. (22) Adjustments are then made to the REMEL to account for: the roadway classification (e.g., collector, secondary, major or arterial), the roadway active width (i.e., the distance between the center of the outermost travel lanes on each side of the roadway), the total average daily traffic (ADT), the travel speed, the percentages of automobiles, medium trucks, and heavy trucks in the traffic volume, the roadway grade, the angle of view (e.g., whether the roadway view is blocked), the site condition“ (“hard” or “soft” relates to the absorption of the ground, pavement, or landscaping), and the percentage of total ADT which flows each hour throughout a 24-hour period.

6.2 ON-SITE TRAFFIC NOISE PREDICTION MODEL INPUTS
The on-site roadway parameters, including the ADT volumes used for this analysis, are presented in Table 6-1. Based on the City of Vallejo General Plan Circulation Element Map MTC-3, I-780 is classified as a four (4) lane divided Freeway. (23) Future average daily traffic volumes, shown on Table 6-1, were obtained from the City of Vallejo General Plan Update and Sonoma Boulevard Specific Plan EIR (24), and reflect future long-range traffic conditions needed to assess the onsite traffic noise environment and to identify the appropriate noise mitigation measures that address the worst-case future noise conditions.

Table 6-2 presents the time-of-day vehicle splits by vehicle type and roadway classification, and Table 6-3 presents the total traffic flow distributions (vehicle mixes) used for this analysis (25).

The vehicle mix provides the hourly distribution percentages of automobiles, medium trucks, and heavy trucks for input into the FHWA Model based on roadway types. The vehicle splits shown in Table 6-2 are reported as a percentage of the overall percentage.

For the purposes of this analysis, soft site conditions were used to analyze the on-site traffic noise impacts for the Project study area. Soft site conditions account for the sound propagation loss over natural surfaces such as normal earth and ground vegetation. A conservative -3dBA offset was applied to future 1-780 traffic noise levels to account for shielding of the western and northern portion of the Project site that would be provided by existing knoll, reducing full exposure to 1-780 traffic noise levels. Research by Caltrans has shown that the use of soft site conditions and applying a shielding offset to account for intervening topographic features is appropriate for the application of the FHWA traffic noise prediction model used in this analysis.

To predict the future noise environment at each building within the Project site, coordinate information was collected to identify the noise transmission path between the noise source and receiver. The coordinate information is based on the Project site plan showing the location of each building, as shown in Exhibit 1-B. The site plan is used to identify the relationship between the roadway centerline elevation, the pad elevation and the centerline distance to any intervening noise barriers or topography, and the building façade. The exterior noise level impacts were placed five feet above the finished floor elevation at the outdoor living areas and proposed building façades. Second-floor receivers were located 14 feet above the finished floor elevation. Appendix 4-1 shows the scaled site plan.

15304-07-Noise_Study.docx
29 7 ON-SITE TRANSPORTATION NOISE IMPACTS
An on-site exterior noise impact analysis has been completed to determine the noise exposure levels that would result from adjacent traffic noise sources in the Project study area, and to identify potential noise control measures that would achieve acceptable Project exterior and interior noise levels. The primary source of traffic noise affecting the Project site is anticipated to be from I-780. The Project will experience some background traffic noise from the Project’s internal local streets, however, due to low traffic volume/speed, traffic noise from these roads will not make a significant contribution to the noise environment. Modeled receiver locations are shown in Exhibit 7-A.

7.1 EXTERIOR NOISE ANALYSIS
Using the FHWA traffic noise prediction model and the parameters outlined in Tables 6-1 to 6-3, the expected future exterior noise levels were calculated at the private outdoor living spaces (backyards) and at the residential building façades. Table 7-1 presents a summary of future exterior noise levels at the private outdoor living spaces (backyards) and at the residential building façades. The on-site transportation analysis indicates that the unmitigated exterior noise levels for on-site receivers are estimated to range from 46.5 to 68.8 dBA CNEL. The Exterior traffic noise analysis calculations are provided in Appendix 7.1.

To satisfy the City of Vallejo exterior noise level standard of 60 dBA Ldn for single-family residential land uses, the construction of a noise barrier is recommended for the outdoor living area (backyards) of Lots 3, 7 through 9, 16, and 17 through 20, adjacent to I-780. Specifically, a minimum 4-foot-high noise barrier is recommended for Lot 9, 5-foot minimum height barriers for Lots 8, 16, and 18 through 20, and 6-foot minimum height barriers for Lots 3, 7, and 9. With the recommended noise barriers shown in Exhibit ES-A, the future exterior noise levels will range from 46.5 to 60.0 dBA CNEL. This noise analysis shows that the recommended noise barrier will satisfy the City of Vallejo exterior noise level standards for residential land uses adjacent to I-780.

The effective noise barrier height recommendations represent the minimum wall and/or berm combination height required to satisfy the City of Vallejo exterior noise level standards. As such, the future on-site traffic noise impacts at the private outdoor living spaces (backyards) are considered less than significant impacts.

2 Exterior noise calculations are included in Appendix 7.1.

7.2 INTERIOR NOISE ANALYSIS
To ensure that the interior noise levels comply with the City of Vallejo interior noise level standard of 45 dBA CNEL, future noise levels were calculated at the estimated building façade locations. It should be noted that Project architectural plans are unavailable and the Project should provide a final interior noise analysis as part of the plan check process.

7.2.1 NOISE REDUCTION METHODOLOGY
The interior noise level is the difference between the predicted exterior noise level at the building facade and the noise reduction of the structure. Typical building construction will provide a Noise Reduction (NR) of approximately 12 dBA with "windows open" and a minimum 25 dBA noise reduction with "windows closed." (3) However, sound leaks, cracks and openings within the window assembly can greatly diminish its effectiveness in reducing noise. Several methods are used to improve interior noise reduction, including: (1) weather-stripped solid core exterior doors; (2) upgraded dual glazed windows; (3) mechanical ventilation/air conditioning; and (4) exterior wall/roof assembles free of cut outs or openings.

Vista Cove Noise Impact Analysis
15304-07-Noise_Study.docx
32 7.2.2 INTERIOR NOISE LEVEL ASSESSMENT
Tables 7-2 to 7-3 show that the buildings adjacent to I-780 will experience future unmitigated noise levels ranging from 46.1 to 60.0 dBA CNEL at first-floor building façades and 51.3 to 69.9 dBA CNEL at second-floor building façades.

The interior noise level analysis shows that the City of Vallejo 45 dBA CNEL interior noise standard can be satisfied at most locations with no requirements, with a windows closed condition and a means of mechanical ventilation (e.g., air conditioning). Therefore, standard construction without upgraded windows or doors will comply with the City of Vallejo interior noise level standard of 45 dBA CNEL.

35 8 OFF-SITE TRANSPORTATION NOISE IMPACTS
The expected Project is anticipated to generate approximately 510 trips per day. The location where the greatest chance of an impact occurs is at the residence near the Project site entrance and at Shady Lane and Wildflower Avenue. Assuming a typical speed of 25 mph, a predominately automobile traffic mix, and without no barriers, the Project is predicted to generate a noise level of 50.2 dBA CNEL at the nearest building façade of 196 Wildflower Avenue. Therefore, the Project would not expose existing noise-sensitive receivers to excessive noise levels, and the off-site traffic noise level impacts due to the Project are considered less than significant.

37 9 SENSITIVE RECEIVER LOCATIONS
To assess the potential for long-term operational and short-term construction noise impacts, the following sensitive receiver locations, as shown on Exhibit 9-A, were identified as representative locations for analysis. Sensitive receivers are generally defined as locations where people reside or where the presence of unwanted sound could otherwise adversely affect the use of the land.

Noise-sensitive land uses are generally considered to include schools, hospitals, single-family dwellings, mobile home parks, churches, libraries, and recreation areas. Moderately noisesensitive land uses typically include multi-family dwellings, hotels, motels, dormitories, outpatient clinics, cemeteries, golf courses, country clubs, athletic/tennis clubs, and equestrian clubs. Land uses that are considered relatively insensitive to noise include business, commercial, and professional developments. Land uses that are typically not affected by noise include:
industrial, manufacturing, utilities, agriculture, undeveloped land, parking lots, warehousing, liquid and solid waste facilities, salvage yards, and transit terminals.

To describe the potential off-site Project noise levels, six receiver locations in the vicinity of the Project site were identified. All distances are measured from the Project site boundary to the outdoor living areas (e.g., private backyards) or at the building façade, whichever is closer to the Project site. The selection of receiver locations is based on FHWA guidelines and is consistent with additional guidance provided by Caltrans and the FTA, as previously described in Section 5.2.

Other sensitive land uses in the Project study area that are located at greater distances than those identified in this noise study will experience lower noise levels than those presented in this report due to the additional attenuation from distance and the shielding of intervening structures. Distance is measured in a straight line from the project boundary to each receiver location.

R1: Location R1 represents existing noise sensitive single-family residence at 190 Buckeye Lane, approximately 90 feet southwest of the Project site. Receiver R1 is placed near the private outdoor living area (backyard) facing the Project site.

R2: Location R2 represents the existing noise sensitive single-family residence at 180 Ironwood Lane, approximately 80feet south of the Project site. Receiver R2 is placed near the private outdoor living area (backyard) facing the Project site.

R3: Location R3 represents the existing noise sensitive single-family residence at 196 Shady Lane, approximately 30 feet south of the Project site. Receiver R3 is placed near the private outdoor living area (backyard) facing the Project site.

R4: Location R4 represents the existing noise sensitive single-family residence at 156 Wildflower Avenue, approximately 114 feet west of the Project site. Receiver R4 is placed near the private outdoor living area (backyard) facing the Project site.

R5: Location R5 represents the existing noise sensitive single-family residence at 124 Shady Lane, approximately 188 feet west of the Project site. Receiver R5 is placed near the private outdoor living area (backyard) facing the Project site.

R6: Location R6 represents the existing noise sensitive Saint Patrick Saint Vincent High School at 1500 Benicia Road and the multi-family uses to the east of the school, approximately 339 feet north of the Project site. Receiver R6 is representative of an outdoor area and the building façade, in terms of distance.

39 10 OPERATIONAL NOISE IMPACTS
This section analyzes the potential stationary-source operational noise impacts at the nearest receiver locations, identified in Section 9, resulting from the operation of the proposed Vista Cove Project. Exhibit 10-A identifies the representative noise source locations used to assess the operational noise levels.

10.1 OPERATIONAL NOISE SOURCES
This operational noise analysis is intended to describe noise level impacts associated with the expected typical of daytime and nighttime activities at the Project site. To present the potential worst-case noise conditions, this analysis assumes the Project would be operational 24 hours per day, seven days per week. The on-site Project-related noise sources are expected to include: air conditioning units.

AIR CONDITIONING UNITS
To assess the noise levels created by the air conditioning units, reference noise levels were taken from equipment specifications for a 3-ton residential packaged air conditioning unit (Carrier Model: R4A4S18AKANA). Each air conditioning unit was modeled as operating 60 minutes per hour during the daytime and nighttime. For this noise analysis, the air conditioning units are expected to be ground-mounted adjacent to the proposed buildings. The air conditioning units are anticipated to be located 3 feet above the ground level. According to the manufacturer’s specification sheets, the Carrier R4A4S18AKANA generates a maximum sound power level of 76 dBA Lw for 4 to 5-ton units or approximately 44.4 dBA Lmax at 50 feet.

10.2 REFERENCE NOISE LEVELS
To estimate the Project operational noise impacts, reference noise level measurements were collected from similar types of activities to represent the noise levels expected with the development of the proposed Project. This section provides a detailed description of the reference noise level measurements shown in Table 10-1 used to estimate the Project operational noise impacts. These sources of noise activity will likely vary throughout the day.

41 10.3 CADNAANOISE PREDICTION MODEL
To fully describe the exterior operational noise levels from the Project, Urban Crossroads, Inc. developed a noise prediction model using the CadnaA (Computer Aided Noise Abatement) computer program. CadnaA can analyze multiple types of noise sources using the spatially accurate Project site plan, georeferenced Nearmap aerial imagery, topography, buildings, and barriers in its calculations to predict outdoor noise levels.

Using the ISO 9613 protocol, CadnaA will calculate the distance from each noise source to the noise receiver locations, using the ground absorption, distance, and barrier/building attenuation inputs to provide a summary of noise level at each receiver and the partial noise level contributions by noise source. Consistent with the ISO 9613 protocol, the CadnaA noise prediction model relies on the reference sound power level (Lw) to describe individual noise sources. While sound pressure levels (e.g., Leq) quantify in decibels the intensity of given sound sources at a reference distance, sound power levels (Lw) are connected to the sound source and are independent of distance. Sound pressure levels vary substantially with distance from the source and diminish because of intervening obstacles and barriers, air absorption, wind, and other factors. Sound power is the acoustical energy emitted by the sound source and is an absolute value that is not affected by the environment.

The operational noise level calculations provided in this noise study account for the distance attenuation provided due to geometric spreading, when sound from a localized stationary source (i.e., a point source) propagates uniformly outward in a spherical pattern. A default ground attenuation factor of 0.5 was used in the CadnaA noise analysis to account for mixed ground representing a combination of hard and soft surfaces. Appendix 10.1 includes the detailed noise model inputs used to estimate the Project operational noise levels presented in this section.

10.4 PROJECT OPERATIONAL NOISE LEVELS
Using the reference noise levels to represent the proposed Project operations that include air conditioning units, Urban Crossroads, Inc. calculated the operational source noise levels that are expected to be generated at the Project site and the Project-related noise level increases that would be experienced at each of the sensitive receiver locations. Table 10-2 shows the Project operational noise levels during the daytime hours of 7:00 a.m. to 10:00 p.m. The daytime hourly noise levels at the off-site receiver locations are expected to range from 24.6 to 34.3 dBA Leq.

42 10.5 PROJECT OPERATIONAL NOISE LEVEL COMPLIANCE
To demonstrate compliance with local noise regulations, the Project-only operational noise levels are evaluated against exterior noise level thresholds based on the City of Vallejo exterior noise level standards at nearby noise-sensitive receiver locations. Table 10-4 shows the operational noise levels associated with Vista Cove Project will satisfy the City of Vallejo daytime 60 dBA Leq and nighttime 50 dBA Leq exterior noise level standards at all nearby noise sensitive receiver locations. Therefore, the operational noise impacts are considered less than significant at the nearby noise-sensitive receiver locations.

43 11 CONSTRUCTION IMPACTS
This section analyzes potential impacts resulting from the short-term construction activities associated with the development of the Project. Exhibit 11-A shows the construction noise source locations in relation to the nearby sensitive receiver locations previously described in Section 9.

11.1 CONSTRUCTION NOISE LEVELS
Noise generated by the Project construction equipment will include a combination of trucks, power tools, concrete mixers, and portable generators that when combined can reach high levels. The number and mix of construction equipment is expected to occur in the following stages:
 Site Preparation
 Grading
 Building Construction
 Paving
 Architectural Coating

11.2 CONSTRUCTION REFERENCE NOISE LEVELS
To describe peak construction noise activities, this construction noise analysis was prepared using reference noise level measurements published in the Update of Noise Database for Prediction of Noise on Construction and Open Sites by the Department for Environment, Food and Rural Affairs (DEFRA). (27). The DEFRA database provides the most recent and comprehensive source of reference construction noise levels. Table 11-1 provides a summary of the DEFRA construction reference noise level measurements expressed in hourly average dBA Leq using the estimated FHWA Roadway Construction Noise Model (RCNM) usage factors (28) to describe the typical construction activities for each stage of Project construction.

11.3 CADNAANOISE PREDICTION MODEL
To fully describe the construction noise levels from the Project, Urban Crossroads, Inc. developed a noise prediction model using the CadnaA (Computer Aided Noise Abatement) computer program. CadnaA can analyze multiple types of noise sources using the spatially accurate Project site plan, georeferenced Nearmap aerial imagery, topography, buildings, and barriers in its calculations to predict outdoor noise levels.

Using the ISO 9613 protocol, CadnaA will calculate the distance from each noise source to the noise receiver locations, using the ground absorption, distance, and barrier/building attenuation inputs to provide a summary of noise level at each receiver and the partial noise level contributions by noise source. Consistent with the ISO 9613 protocol, the CadnaA noise prediction model relies on the reference sound power level (Lw) to describe individual noise sources. While sound pressure levels (e.g., Leq) quantify in decibels the intensity of given sound sources at a reference distance, sound power levels (Lw) are connected to the sound source and are independent of distance. Sound pressure levels vary substantially with distance from the source and diminish because of intervening obstacles and barriers, air absorption, wind, and other factors. Sound power is the acoustical energy emitted by the sound source and is an absolute value that is not affected by the environment.

The construction noise level calculations provided in this noise study account for the distance attenuation provided due to geometric spreading, when sound from a localized stationary source

46 (i.e., a point source) propagates uniformly outward in a spherical pattern. A default ground attenuation factor of 0.5 was used in the noise analysis to account for mixed ground representing a combination of hard and soft surfaces.

11.4 TYPICAL CONSTRUCTION NOISE ANALYSIS
Using the reference construction equipment noise levels and the CadnaA noise prediction model, calculations of the Project construction noise level impacts at the nearest sensitive receiver locations were completed. To assess the worst-case construction noise levels, the Project construction noise analysis relies on the highest noise level impacts when the equipment with the highest reference noise level is operating at the closest point from the edge of primary construction activity (Project site boundary) to each receiver location. As shown on Table 11-2, the construction noise levels are expected to range from 45.5 to 65.0 dBA Leq, and the highest construction levels are expected to range from 53.3 to 65.0 dBA Leq at the nearest receiver locations. Appendix 11.1 includes the detailed CadnaA construction noise model inputs.

CadnaA construction noise model inputs are included in Appendix 11.1.

11.5 TYPICAL CONSTRUCTION NOISE LEVEL COMPLIANCE
To evaluate whether the Project will generate potentially significant short-term noise levels at nearest receiver locations, a construction-related daytime noise level threshold of 80 dBA Leq is used as a reasonable threshold to assess the daytime construction noise level impacts. The construction noise analysis shows that the nearest receiver locations will satisfy the reasonable daytime 80 dBA Leq significance threshold during Project construction activities as shown on Table 11-3. Therefore, the noise impacts due to Project construction noise is considered less than significant at all receiver locations.

11.6 TYPICAL CONSTRUCTION VIBRATION IMPACTS
Construction activity can result in varying degrees of ground vibration, depending on the equipment and methods used, distance to the affected structures and soil type. It is expected that ground-borne vibration from Project construction activities would cause only intermittent, localized intrusion. Ground-borne vibration levels resulting from typical construction activities occurring within the Project site were estimated by data published by the Federal Transit Administration (FTA). (26) However, while vehicular traffic is rarely perceptible, construction has the potential to result in varying degrees of temporary ground vibration, depending on the specific construction activities and equipment used. Ground vibration levels associated with various types of construction equipment are summarized on Table 11-4. Based on the representative vibration levels presented for various construction equipment types, it is possible to estimate the potential Project construction vibration levels using the following vibration assessment methods defined by Caltrans. To describe the human response (annoyance) associated with vibration impacts Caltrans provides the following equation: PPVequip = PPVref x (25/D)1.1

15304-07-Noise_Study.docx
48 Using the vibration source level of construction equipment provided on Table 11-4 and the construction vibration assessment methodology published by the FTA, it is possible to estimate the Project vibration impacts. Table 11-5 presents the expected Project related vibration levels at the nearby receiver locations. At distances ranging from 29 to 344 feet from the Project construction activities to the nearest adjacent off-site structure, construction vibration velocity levels are estimated to range from less than 0.02 to 0.07 in/sec PPV. Based on maximum acceptable continuous vibration threshold of 0.10 in/sec PPV, the typical Project construction vibration levels will not exceed the vibration thresholds at any local receiver. Additionally, since the vibration levels would be well below 0.30 in/sec PPV, there would be no structural vibration impacts. Therefore, the Project-related vibration impacts associated with construction activities are considered less than significant.

Noise measurement. In determining whether any noise exceeds the maximum exterior noise limits set forth in this chapter, measurements shall be taken at the property line of the property from which the noise emanates, except that for noise emanating from property in a IG Zoning District, measurement shall be taken at boundary of the zoning district in which the property is located. Residential noise levels.

Interior. No person shall operate or cause to be operated within a dwelling unit, any source of sound that causes the sound level when measured inside a neighboring receiving dwelling unit to exceed the allowable noise level, for any period of time.

Exterior. The exterior noise limits for any source of noise within any residential zone shall be reduced by ten dBA between 10:00 p.m. and 7:00 a.m. The exterior noise limits for any source of noise in any zone other than a residential zone shall be reduced between 10:00 p.m. and 7:00 a.m. so that when the noise measured at the property line of a "noise-sensitive use" does not exceed fifty dBA. The interior noise level for steady state continuous noise from exterior sources in any residential bedroom with windows open between 10:00 p.m. and 7:00 a.m. shall not exceed thirty dBA.

Mitigation required. New single-unit residential projects shall be located and designed so the noise levels in private use areas does not exceed sixty Ldn. For new multipleunit residential projects a standard of sixty-five Ldn shall apply to outdoor areas excluding balconies.

Noise from sources not under local jurisdiction such as freeways and aircraft shall be exempt.

Developers of mixed-use projects that include residential development shall notify all potential residents that they may be exposed to noise from adjacent and nearby commercial, retail, entertainment, and circulation activity.

Noise level measurement. The following provisions establish a means for measuring noise levels. Where these provisions conflict with other requirements of the Vallejo Municipal Code, the following shall remain applicable for purposes of the Zoning Code:

Calibration of Meter. The sound level meter shall be approximately calibrated and adjusted as necessary by means of an acoustical calibrator of the coupler-type to assure meter accuracy within the tolerances set forth in American National Standards ANSI-SI.4-1971.

Location of Microphone. All measurements shall be taken at any lot line of a lot within the applicable zoning district. The measuring microphone shall not be less than four feet above the ground, at least four feet distant from walls or other large reflecting surfaces and shall be protected from the effects of wind noises by the use of appropriate wind screens. In cases when the microphone shall be located within ten feet of walls or similar large reflecting surfaces, the actual measured distances and orientation of sources, microphone and reflecting surfaces shall be noted and recorded. In no case shall a noise measurement be taken within five feet of the noise source.

Measured Sound Levels. The measurement of sound level limits shall be the average sound level for a period of one hour.

Compliance. The director may require the applicant for a building permit, prior to the issuance of such permit, to submit such information with respect to proposed machinery, processes, products, or environmental impacts as may be necessary to demonstrate the ability of the proposed uses to comply with the requirements of this chapter.

circulation and transportation systems by increasing
reliance on public transit, ridesharing, walking,
car-sharing, cycling and focusing development
in areas close to transit and employment;
C. Reduce trac impacts within the community
and region, vehicular air pollutant emissions,
energy usage, and ambient noise levels through a
reduction in the number of per capita vehicle miles
traveled and management of trac congestion;
D. Inform residents, workers, employers and
other business owners about travel options
and the impacts of travel choices;
E. Coordinate transportation system management,
TDM, and transportation facility development
strategies Citywide, with other cities in the
region and through regional agencies; and,
F. Support local and regional eorts to relieve
trac congestion in and around the City.

G. e requirements of this Chapter apply to:

1. New multi-unit development of 10 units or more;

2. New non-residential development of
10,000 square feet or more; and
