Noise Analysis
Santa Fe Flores Townhomes Project

Executive Summary
The Santa Fe Flores Townhomes Project (project) is located in the city of San Marcos at 2966, 2972, and 2982 South Santa Fe Avenue, adjacent to North Las Flores Drive. The 2.6-acre (net) project site is comprised of assessor parcel numbers (APNs) 217-161-18, 217-161-19, and 0.37 acres of APN 217- 161-17. The project would require a General Plan A mendment (GPA) and Rezone to allow the development of 46 multi-family residential townhome units. The project also proposes approximately 0.12 acres of off -site improvements, including the construction of a new shared driveway extending into the southern portion of APN 217 -161-17, upgrades to the existing liquor store parking lot, and landscaping within the 8-foot-wide irrevocable offer of dedication area along the project frontage. The liquor store, Gourmet Liquor, located on the southern portion of APN 217- 161-17 is not part of the project and would remain.

This report discusses potential noise impacts from the construction and operation of the project. As part of this assessment, noise levels due to vehicle traffic were calculated and evaluated against City of San Marcos (City) noise and land use compatibility guidelines. In addition to compatibility, the potential for noise to impact adjacent uses from future on-site sources and construction activity was assessed. A summary of the findings is provided below.

Construction Noise
Construction activity is regulated by the City Municipal Code, which limits noise by restricting construction activities to hours unlikely to impact the community. Noise associated with the grading, building, and paving for the project would potentially result in short -term impacts to surrounding residential properties. Construction noise levels would range from 56 to 73 A-weighted decibels equivalent noise level (dB(A) L
eq) at the adjacent properties. Construction activities would generally occur over the period between 7:00 a.m. and 6:00 p.m. on weekdays. Although the existing adjacent uses would be exposed to construction noise levels that may be heard above ambient conditions, the exposure would be temporary and would not exceed 75 dB(A) L eq. As construction activities associated with the project would comply with Section 10.24.020 (b)(9) of the City Municipal Code, temporary increases in noise levels from construction activities would be less than significant.

Traffic Noise
The additional vehicle trips associated with the project would increase noise levels on nearby roadways. A noise increase of 3 dB or more would be considered significant because 3 dB is the level at which an increase in noise is perceptible to a person. Ho wever, the project would not generate enough trips to result in a direct or cumulative noise increase of more than 3 dB. Therefore, the project would result in less than significant direct and cumulative impacts related to traffic noise.

The main source of noise at the project site is vehicle traffic on South Santa Fe Avenue and North Las Flores Drive as well as Sprinters on the adjacent rail line. Exterior noise levels were modeled at the project site to determine compatibility with City standards. The applicable standards for multi-family uses are an exterior noise level of 65 community noise equivalent level (CNEL) and an Noise Analysis
Santa Fe Flores Townhomes Project

interior noise level of 45 CNEL. The project’s exterior useable spaces include second- and third-floor balconies, roof decks, and the five amenity areas located on the south side of Building 1, on the north side of Building 2 , on the east side of Building 4, on the north side of Building 5, and between Buildings 6 and 7. These amenity areas consist of active play areas and passive gathering space. As calculated in this analysis, without consideration of any noise barriers, exterior noise levels are projected to range from 42 to 70 CNEL at the building façades and amenity areas. Noise levels would be compatible with the City’s exterior multi-family noise level standard of 65 CNEL at all locations except the amenity area on the south side of Building 1 ( Amenity Area A, Receiver 1) and the south and east sides of Building 1 facing the roadways (Receivers 8 and 9). In order to reduce noise levels at these locations, the project would include a 6-foot barrier adjacent to the amenity area south of Building 1, and a solid 3.5 -foot barrier on the balconies located on the south and east sides of Building 1 and on the south and east sides of the Building 1 roof deck. With construction of these barriers, exterior noise levels would be reduced to less than 65 CNEL and exterior nois e impacts would be less than significant.

The interior noise level standard is 45 CNEL. Interior noise levels can be reduced through standard construction techniques. When windows are closed, standard construction techniques provide various exterior-to-interior noise level reductions depending on the type of structure and window.

Standard light-frame construction would reduce exterior to interior noise levels by at least 20 dB (Federal Highway Administration 2011). With the installation of windows with a sound transmission class (STC) rating of 25 or higher, interior noise levels within the units in Building 1 would be reduced to 45 CNEL and interior noise levels would be less than significant. Interior noise levels at all other buildings would be 45 CNEL with standard light frame construction and without consideration of specific building components.

On-site Generated Noise
The project site is surrounded by single-family residential uses to the northeast and southeast, multi-family residential uses to the east, a mobile home park to the south, a commercial use to the southwest, and industrial uses to the west and north. The applicable daytime (7:00 a.m. to 10:00 p.m.) and nighttime (10:00 p.m. to 7:00 a.m.) Noise Ordinance limits are 60 dB(A) L eq and 50 dB(A) Leq at the single-family residential uses, 65 dB(A) Leq and 55 dB(A) L eq at the multi -family residential and mobile home park uses, 65 dB(A) Leq and 55 dB(A) Leq at the commercial uses, and 65 dB(A) Leq and 60 dB(A) L eq at the industrial uses. The noise sources on the project site after completion of construction are anticipated to be those that would be typical of any residential use, such as vehicles arriving and leaving, children at play, and landscape maintenance machinery. None of these noise sources are anticipated to violate the Municipal Code. Rooftop heating, ventilating, and air conditioning noise levels were modeled at the property line adjacent properties. As calculated in this analysis, HVAC noise levels would range from 33 to 42 dB(A) Leq at the adjacent properties. Noise levels would not exceed the applicable Noise Ordinance limits at the property lines.

1.0 Introduction

1.1 Project Description
The project is located in the city of San Marcos at 2966, 2972, and 2982 South Santa Fe Avenue adjacent to North Las Flores Drive on assessor parcel numbers (APNs) 217 -161-18, 217-161-19, and

0.37 acres of APN 217-161-17 . The 2.6-acre (net) project site is comprised of APNs 217 -161-18, 217- 161-19, and 0.37 acres of APN 217-161-17. The project also proposes approximately 0.12 acres of off- site improvements, including the construction of a new shared driveway extending into the southern portion of APN 217-161-17, upgrades to the existing liquor store parking lot, and landscaping within the 8-foot-wide irrevocable offer of dedication area along the project frontage. Figure 1 shows the regional location. Figure 2 shows an aerial photograph of the project site and vicinity.

On February 28, 2023, the City of San Marcos City Council adopted a Mitigated Negative Declaration (MND; ND22-008; SCH No. 2022090486), approved a GPA (GPA21-0008), approved a Rezone (21 - 0004), and approved a Multi-Family Site Development Plan (MFSDP21-0002) for the Santa Fe Flores, LP Project (approved project). The requested Rezone (R21-0004) required a second reading prior to approval on March 14, 2023. The approved project evaluated the impacts associated with a GPA to change the land use from Commercial (C) and Light Industrial (L-I) to Medium Density Residential 2 (MDR2) and a zone change from Commercial (C) and Light Industrial (L-I) to Multi-Family Residential (R-3-10) to allow for the construction of 50 multi-family residential townhome units, in conjunction with a Density Bonus, on a 2.23-acre site consisting of two parcels, APNs 217-161-18 and 217-161-19.

Subsequent to MND approval, the applicant modified the site plan and added 0.37 acres of APN 217-161-17 through a lot line adjustment to be proces sed. The project would require a GPA from Medium Density Residential 2 (MDR2) to Medium High Density Residential (MHDR) for APNs 217 - 161-18 and 217-161-19, and a GPA from Commercial (C) to Medium High Density Residential (MHDR) for 0.37 acres of the northern portion of APN 217-161-17. Additionally, the project would rezone APNs 217-161-18 and 217-161-19 from Multi-Family Residential 3 (R-3-10) to Multi-Family Residential (R-3- 6) and 0.37 acres of the northern portion of APN 217-161-17 from Commercial (C) to Mu lti-Family Residential (R-3-6). The project would develop 46 multi-family residential townhome units in seven buildings that would be three stories in height. Vehicle parking would include 92 spaces within attached garages and 15 guest spaces. The liquor store would not be part of the project and would remain. Project grading would include 23,300 cubic yards of cut and 3,200 cubic yards of fill resulting in the export of 20,100 cubic yards of soil. Figure 3 shows the proposed site plan.

Noise Analysis
Santa Fe Flores Townhomes Project

1.2 Fundamentals of Noise
Sound levels are described in units called the decibel (dB). Decibels are measured on a logarithmic scale that quantifies sound intensity in a manner similar to the Richter scale used for earthquake magnitudes. Thus, a doubling of the energy of a noise sou rce, such as doubling of traffic volume, would increase the noise level by 3 dB; a halving of the energy would result in a 3 dB decrease.

However, human perception of noise has no simple correlation with acoustical energy. A change in noise levels is generally perceived as follows: 3 A -weighted dB (dB(A)) barely perceptible, 5 dB(A) readily perceptible, and 10 dB(A) perceived as a doubling or halving of noise (California Department of Transportation [Caltrans] 2013).

In technical terms, sound levels are described as either a “sound power level” or a “sound pressure level,” which while commonly confused, are two distinct characteristics of sound. Both share the same unit of measure, the dB. However, sound power, expressed as L pw, is the energy converted into sound
by the source. As sound energy travels through the air, it creates a sound wave that exerts pressure on receivers such as an eardrum or microphone, the sound pressure level. Sound measurement instruments only measure sound pressure, and limits used in standards are generally sound pressure levels.

The human ear is not equally sensitive to all frequencies within the sound spectrum. To accommodate this phenomenon, the A -scale, which approximates the frequency response of the average young ear when listening to most ordinary everyday sounds, was devise d. When people make relative judgments of the loudness or annoyance of a sound, their judgments correlate well with the A-scale sound levels of those sounds. Therefore, the “A -weighted” noise scale is used for measurements and standards involving the human perception of noise. Noise levels using A-weighted measurements are designated with the notation dB(A).

1.2.1 Descriptors
The impact of noise is not a function of loudness alone. The time of day when noise occurs and the duration of the noise are also important. In addition, most noise that lasts for more than a few seconds is variable in its intensity. Consequently, a variety of noise descriptors has been developed.

The noise descriptors used for this study are the equivalent noise level (L eq) and the community noise
equivalent level (CNEL). The Leq is the equivalent steady-state noise level in a stated period of time that is calculated by averaging the acoustic energy over a time period; when no period is specified, a 1-hour period is assumed.

The CNEL is a 24 -hour equivalent sound level. The CNEL calculation applies an additional 5 dB(A) penalty to noise occurring during evening hours, between 7:00 p.m. and 10:00 p.m., and a 10 dB(A) penalty is added to noise occurring during the night, between 10:00 p.m. and 7:00 a.m. These increases for certain times are intended to account for the added sensitivity of humans to noise during the evening and night.

Noise Analysis
Santa Fe Flores Townhomes Project

1.2.2 Propagation
Sound from a localized source (approximating a “point” source) radiates uniformly outward as it travels away from the source in a spherical pattern, known as geometric spreading. The sound level decreases or drops off at a rate of 6 dB(A) for each doubling of the distance (e.g., a noise level of 60 dB(A) at 50 feet from a point source would attenuate to 54 dB(A) at 100 feet).

Traffic noise is not a single, stationary point source of sound. The movement of vehicles makes the source of the sound appear to emanate from a line (line source) rather than a point when viewed over some time interval. The drop-off rate for a line source is 3 dB(A) for each doubling of distance (e.g., a noise level of 60 dB(A) at 50 feet from a line source would attenuate to 57 dB(A) at 100 feet).

The propagation of noise is also affected by the intervening ground, known as ground absorption.

A hard site (such as parking lots or smooth bodies of water) receives no additional ground attenuation, and the changes in noise levels with distance (drop-off rate) are simply the geometric spreading of the source. A soft site (such as soft dirt, grass, or scattered bushes and trees) provides an additional ground attenuation value of 1.5 dB(A) per doubling of distance. For example, under soft site conditions, a noise level of 60 dB(A) at 50 feet from a point source would attenuate to 52.5 dB(A) at 100 feet, and a noise level of 60 dB(A) at 50 feet from a line source would attenuate to 55.5 dB(A) at 100 feet.

2.0 Applicable Noise Standards

2.1 General Plan
The Noise Element of the City General Plan provides land use compatibility guidelines to ensure that new developments are sited, designed, and constructed in such a manner that ambient noise levels would not create an unacceptable noise environment for the occupants and patrons of the new development. Table 1 provides the interior and exterior noise guidelines for various types of uses and developments.

The project proposes multi-family residential uses. As shown in Table 1, the applicable standards for multi-family uses are an exterior noise level of 65 CNEL and an interior noise level of 45 CNEL. The exterior noise level standard is applicable at the proposed exterior use areas. For the proposed project, this includes second- and third-floor balconies, rooftop decks, and the five proposed amenity areas consisting of active play areas and passive gathering areas.

3For single-family detached dwelling units, “exterior noise level” is defined as the noise level measured at an outdoor living area that adjoins and is on the same lot as the dwelling.

2.2 Municipal Code

2.2.1 Title 10, Chapter 10.24 – Construction
Section 10.24.020 (b)(9) of the City Municipal Code identifies permissible hours for general construction activities. Excluding City holidays, construction may occur weekdays from 7:00 a.m. to 6:00 p.m. or Saturdays from 8:00 a.m. to 5:00 p.m. Grading is often the loudest phase of construction.

Section 17.32.180 restricts grading and earthworks activities to between the hours of 7:00 a.m. and 4:30 p.m., Monday through Friday.

2.2.2 Title 20 – Zoning Ordinance
City Municipal Code Title 20 – Zoning Ordinance contains General Development Standards.

Performance standards in Section 20.300.070 (f) set restrictions on noise levels by zoning. No person shall create or allow the creation of exterior noise that causes the noise level to exceed the noise standards shown in Table 2.

The project site is surrounded by si ngle-family residential uses to the northeast and southeast, multi-family residential uses to the east, a mobile home park to the south, a commercial use to the southwest, and industrial uses to the west and north.

2.3 California Green Building Standards Code –
Environmental Comfort
Interior noise levels for habitable rooms are regulated also by Title 24 of the California Code of Regulations (CCR) California Noise Insulation Standards. Title 24, Chapter 12, Section 1206.4, of the 2019 California Building Code requires that interior noise levels attributable to exterior sources not exceed 45 CNEL in any habitable room. A habitable room is a room used for living, sleeping, eating, or cooking. Bathrooms, closets, hallways, utility spaces, and similar areas are not considered habitable rooms for this regulation (24 CCR, Chapter 12, Section 1206.4).

3.0 Existing Conditions
Existing noise levels in the vicinity of the project site were measured on March 22, 2022 , using one Larson-Davis Model LxT, Type 1 Integrating Sound Level Meter, serial number 3895. The following parameters were used:

Filter: A-weighted
Response: Slow
Interval Period 1 minute
Time History Period: 5 seconds
The meter was calibrated before and after each measurement. The meter was set 5 feet above the ground level for each measurement.

Noise measurements were taken to obtain typical ambient noise levels at the project site and in the vicinity. The weather was sunny and warm. Two 15-minute measurements were taken, as described Noise Analysis
Santa Fe Flores Townhomes Project

below. The measurement locations are shown on Figure 4, and detailed data is contained in Attachment 1.

Measurement 1 was located near the southern project boundary, 50 feet north of S outh Santa Fe Avenue. Noise levels were measured for 15 minutes. The main noise source at this location was vehicle traffic on South Santa Fe Avenue . Vehicle traffic on South Santa Fe Avenue was counted during the measurement period. The average measured noise level was 63.2 dB(A) Leq.

Measurement 2 was located near the eastern project boundary, approximately 50 feet west of North Las Flores Drive. Noise levels were measured for 15 minutes. The main noise source at this location was vehicle traffic on North Las Flores Drive. Secondary sources of noise included vehicle traffic on South Santa Fe Avenue . Vehicle traffic on North Las Flores Drive was counted during the measurement period. The average measured noise level was 57.5dB(A) L eq.

Noise measurements are summarized in Table 3. Traffic counts conducted during Measurements 1 and 2 are summarized in Table 4.

Noise Analysis
Santa Fe Flores Townhomes Project

4.0 Analysis Methodology
Noise level predictions and contour mapping were developed using noise modeling software, SoundPlan Essential, version 4.1 (Navcon Engineering 2018). SoundPLAN calculates noise propagation based on the International Organization for Standardization method (ISO 9613 -2 – Acoustics, Attenuation of Sound during Propagation Outdoors). The model calculates noise levels at selected receiver locations using input parameter estimates such as total noise generated by each noise source; distances between sources, barriers, and receivers; and shielding provided by intervening terrain, barriers, and structures. The model outputs can be developed as noise level contour maps or noise levels at specific receivers. In all cases, receivers were modeled at 5 feet above ground elevation, which represents the average height of the human ear.

4.1 Construction Noise Analysis
Project construction noise would be generated by diesel engine-driven construction equipment used for site preparation and grading, building construction, loading, unloading, and placing materials and paving. Diesel engine-driven trucks also would bring materials to the site and remove the soils from excavation.

Construction equipment with a diesel engine typically generates maximum noise levels from 70 to 95 dB(A) Leq at a distance of 50 feet (Federal Highway Administration [FHWA] 2006 and 2008, Federal Transit Authority 2018). D uring construction, equipment moves to different locations and goes through varying load cycles, and there are breaks for the operators and for non­equipment tasks, such as measurement. Table 5 summarizes typical construction equipment noise levels and duty cycles.

Construction equipment would generate maximum noise levels between 70 and 95 dB(A) maximum noise level ( Lmax) at 50 feet from the source when in operation. During excavation, grading, and paving operations, equipment moves to different locations and goes through varying load cycles, and there are breaks for the operators and for non­equipment tasks, such as measurement. Average construction noise levels were calculated for the simultaneous operation of three common pieces of construction equipment: dozer, e xcavator, and loader . FTA guidance recommends analyzing the two noisiest pieces of construction equipment (FTA 2018), therefore this is a conservative assessment.

The usage factors were applied to the maximum noise level at 50 feet for each piece of equipment, and then noise levels were added logarithmically. Hourly average noise levels would be approximately 85 dB(A) L
eq at 50 feet from the center of construction activity when assessing three pieces of common construction equipment working simultaneously.

4.2 Traffic Noise Analysis

4.2.1 On-site Traffic and Rail Noise
The SoundPLAN program uses the FHWA Traffic Noise Model algorithms and reference levels to calculate noise levels at selected receiver locations. The model uses various input parameters, such as projected hourly average traffic rates; vehicle mix, distribution, and speed; roadway lengths and gradients; distances between sources, barriers, and receivers; and shielding provided by intervening terrain, barriers, and structures. Receivers, roadways, and barriers were input into the model using three-dimensional coordinates. The locations of future buildings were obtained from project plans and drawings.

Noise Analysis
Santa Fe Flores Townhomes Project

The main source of traffic noise at the project site is vehicle traffic on South Santa Fe Avenue and North Las Flores Drive as well as Sprinters on the adjacent rail line. Future year 205 0 with project traffic volumes for South Santa Fe Avenue were obtained from the Traffic Impact Analysis prepared for the project (Linscott, Law & Greenspan , Engineers [LLG] 2026). Future year 2050 traffic volumes for North Las Flores Drive were obtained from San Diego Association of Governments (SANDAG) traffic projections (SANDAG 2025). A vehicle classification mix of 93.0 percent automobiles, 3.0 percent medium trucks, 2.0 percent heavy trucks, 1.0 percent buses, and 1.0 percent motorcycles were modeled. Based on the field traffic counts, this classification mix is conservative.

Table 6 summarizes the traffic volumes and vehicle classification mixes for the modeled roadways.

The project site is also located approximately 150 feet southwest of the Sprinter rail line. The Sprinter is a light rail commuter train operated by the North County Transit District. The east -west Sprinter rail spans 22 miles from Oceanside to Escondido. The Palomar College Station is the closest Sprinter station to the project site. Fridays experience the largest number of daily Sprinter trains. The number of Friday daytime, evening, and nighttime Sprinter trains was obtained from published schedules and is summarized in Table 7.

4.2.2 Off-site Traffic Noise
Off-site traffic noise was modeled using the FHWA Traffic Noise Prediction Model algorithms and reference levels. Traffic noise levels were calculated at 50 feet from the centerline of the affected roadways to determine the noise level increase associated with the project. The model uses various input parameters, such as traffic volumes, vehicle mix, distribution, and speed.

Noise Analysis
Santa Fe Flores Townhomes Project

The roadways included in the traffic impact analysis are South Santa Fe Avenue, Hollencrest Road, and North Rancho Santa Fe Road . Traffic noise levels were calculated based on the total average daily traffic volumes on each roadway segment. For modeling purposes, “hard” ground conditions were used for the analysis of future conditions, since a majority of the project area is paved and the hard site provides the most conservative impact assessment.

Existing (year 2022), near term (year 2027 ), and future (year 2050) traffic volumes with and without the project were obtained from the project traffic impact analysis ( LLG 2026). Table 8 summarizes the future traffic volumes for the area roadway segments. Modeled noise levels do not account for shielding provided by intervening barriers and structures.

4.3 On-site Generated Noise Analysis
On-site noise sources on the project site after completion of construction are anticipated to be those that would be typical of any multi-family use, such as vehicles arriving and leaving, children at play, and landscape maintenance machinery. None of these noise sources are anticipated to violate the City Municipal Code or result in a substantial permanent increase in existing noise levels. However, the project would include rooftop heating, ventilation, and air conditioning (HVAC) equipment. Noise levels due to HVAC equipment were modeled and compared to City limits (see Table 2).

The HVAC equipment would be located on the roof with screened walls. It is not known at this time which manufacturer, brand, or model of unit or units will be selected for use in the project. For the purposes of this analysis, to determine what general noise levels the HVAC units would generate, it was assumed that the rooftop units would be similar to a Carrier unit with a sound power level of 75 dB(A). Noise specifications are contained in Attachment 2. All units were modeled at full capacity during the daytime and nighttime hours.

Noise Analysis
Santa Fe Flores Townhomes Project

Noise levels due to on -site sources were modeled using SoundPLAN. The SoundPLAN program models noise propagation following the International Organization for Standardization method ISO 9613-2 – Acoustics, Attenuation of Sound during Propagation Outdoors . The model calculates noise levels at selected receiver locations using input parameter estimates such as total noise generated by each noise source; distances between sources, barriers, and receivers; and shielding provided by intervening structures.

5.0 Future Acoustical Environment and Impacts

5.1 Construction Noise
Noise associated with the grading, building, and paving for the project would potentially result in short-term impacts to surrounding residential properties. There are residential uses located northeast, east, southeast, and south of the project site. A variety of noise-generating equipment would be used during the construction phase of the project, such as excavators, backhoes, front-end loaders, and concrete saws, along with others. The exact number and pieces of construction equipment required are not known at this time. As discussed, average construction noise levels were calculated. Based on this analysis, hourly average noise levels would be approximately 85 dB(A) L eq
at 50 feet from the center of construction activity when assessing three pieces of common construction equipment working simultaneously. Construction noise is considered a point source and would attenuate at approximately 6 dB(A) for every doubling of distance. To reflect the nature of grading and construction activities, equipment was modeled as an area source distributed over the project footprint. Noise levels were modeled at a series of 18 receivers located at the adjacent uses. The results are summarized in Table 9. Modeled receiver locations and construction noise contours are shown in Figure 5. SoundPLAN data is contained in Attachment 3.

Noise Analysis
Santa Fe Flores Townhomes Project

As shown, construction noise levels would range from 56 to 73 dB(A) Leq at the adjacent uses. The City’s Municipal Code does not place noise limit restrictions on construction activities; however, other jurisdictions commonly apply a noise level limit of 75 dB(A) Leq at residential uses. Construction noise levels would not exceed 75 dB(A) L eq. Construction activities would generally occur over the period between 7:00 a.m. and 6:00 p.m. on weekdays. Although the existing adjacent uses would be exposed to construction noise levels that may be heard above ambient conditions, the exposure would be temporary and would not exceed 75 dB(A) Leq. As construction activities associated with the project would comply with the time limits established in Section 10.24.020 (b)(9) of the City Municipal Code, temporary increases in noise levels from construction activities would be less than significant.

5.2 Traffic Noise

5.2.1 On-site Traffic and Rail Noise
On-site traffic and rail noise contours were developed using the SoundPLAN program. Noise level contours were modeled at the first-floor level. These contours take into account shielding provided by the proposed buildings and grading. Future vehicle and rail traffic noise-level contours are shown in Figure 6. SoundPLAN data are contained in Attachment 4.

As discussed in Section 2.1, the exterior noise level standard for multi-family uses is 65 CNEL. This standard is applicable at exterior use areas which include second- and third-floor balconies, rooftop decks, and the five proposed amenity areas consisting of active play areas and passive gathering areas The interior noise level standard is 45 CNEL. To refine the noise analysis and determine noise levels at exterior use areas and the building façade, exterior noise levels were calculated at a series of fir st- through third-floor specific receiver locations at the outdoor use areas and around the proposed building. Modeled receiver locations are shown in Figure 6. Table 10 summarizes the projected future noise levels at the 26 modeled receivers. Modeled noise levels shown in Table 10 do not include noise reduction provided by any noise barriers.

Bold = Exceeds 65 CNEL

As shown, exterior noise levels are projected to range from 42 to 70 CNEL at the building façade s and amenity areas. Noise levels would be compatible with the City’s exterior multi-family noise level standard of 65 CNEL at all locations except the amenity area on the south side of Building 1 (Amenity Area A, Receiver 1) and the south and east sides of Building 1 facing the roadways (Receivers 8 and 9). There are second-floor balconies on the south side of Building 1 and third-floor balconies on the east side of Building 1 and a rooftop deck. These balconies and rooftop deck could be exposed to noise levels that exceed 65 CNEL. Based upon these findings, noise control recommendations are necessary at the amenity area south of Building 1, at the balconies on the south and east sides of Building 1, and on the south and east sides of the Building 1 roof deck in order to comply with the City’s noise standard of 65 CNEL. A 6-foot barrier adjacent to the amenity area as shown in Figure 6 was modeled using SoundPLAN and would be necessary to reduce noise levels to 65 CNEL or less Noise Analysis
Santa Fe Flores Townhomes Project

at this active play area. Modeling data is provided in Attachment 4. To determine the required barrier heights at the Building 1 balconies and roof deck, the Fresnel barrier noise reductions were modeled.

The balcony and roof deck barriers were modeled using this equation -based method rather than SoundPLAN because of the geometry of these barriers when elevated on balconies and the roof deck. These reductions are based on distance, source height, receiver elevation, and barrier height.

The Fresnel barrier reduction calculations are provided as Attachment 5. It was calculated that a

3.5-foot balcony barrier would provide a 7.4 dB reduction at the balconies on the south side of Building 1 (Receiver 2), a 5.9 dB reduction at the balconies on the east side of Building 1 (Receiver 3), and a 7.0 dB reduction on the roof deck. In order to reduce noise levels at these locations, the project would include a 3.5-foot balcony railing as a solid barrier. With construction of these barriers, exterior noise levels would be reduced to less than 65 CNEL.

The interior noise level standard is 45 CNEL. Interior noise levels can be reduced through standard construction techniques. When windows are closed, standard construction techniques provide various exterior-to-interior noise level reductions depending on the type of structure and window.

Standard light-frame construction would reduce exterior to interior noise levels by at least 20 dB (FHWA 2011).

As shown in Table 10, noise levels would be as high as 70 CNEL at the south side of Building 1 and 66 CNEL at the east side of Building 1. While the proposed 3.5 -foot balcony barriers would reduce noise levels to 65 CNEL at a seated receiver, the entire building façade would not get the same noise attenuation, and the evaluation of specific building components is required. The sound transmission class (STC) rating of windows, walls, and roofs is an integer value that rates how well a building component attenuates noise. The STC rating generally reflects the decibel reduction that a building component can achieve. Standard walls and roofs typically have STC ratings greater than 40, while window components have lower ratings; thus, this analysis focuses on the minimum required window STC ratings. Because a noise reduction of up to 25 dB(A) is required to achieve interior noise levels of 45 CNEL or less, window components with an STC rating of 25 or higher are required for units located on the south and east side of Building 1. With the installation of windows with an STC rating of 25 or higher, interior noise levels within the units in Building 1 would be reduced to 45 CNEL and interior noise levels would be less than significant. Interior noise levels at all other buildings would be 45 CNEL with standard light frame construction and without consideration of specific building components.

5.2.2 Off-site Traffic Noise
The project would increase traffic volumes on local roadways. However, t he project would not substantially alter the vehicle classifications mix on local or regional roadways, nor would the project alter the speed on an existing roadway or create a new roadway. Thus, the primary factor affecting off-site noise levels would be increased traffic volumes. While changes in noise levels would occur along any roadway where project -related traffic occurs, for noise assessment purposes, noise level increases are assumed to be greatest nearest the project site, as this location would represent the greatest concentration of project -related traffic. Traffic noise increases attributable to the project were assessed against a significance threshold of 3 dB, which is the level at which an increase in noise is considered to be barely perceptible (Caltrans 2013).

Table 11 presents a conservative assessment of traffic noise levels based on the existing, near term (year 2027), and future (year 2050) noise levels without and with the project. Table 11 also summarizes the direct and cumulative traffic noise level increases due to the project. Noise level calculations are contained in Attachment 6.

As shown, the project would not result in a direct or cumulative noise increase of more than 3 dB.

Therefore, the project would result in less than significant direct and cumulative impacts related to traffic noise.

5.3 On-site Generated Noise
The primary noise sources on-site would be HVAC equipment. Rooftop HVAC equipment that would have the potential to produce noise in excess of City limits (see Table 2). Using the on -site noise source parameters discussed in Section 4.3, noise levels were modeled at a series of 17 receivers located at the adjacent properties. Noise generated by HVAC equipment would occur on an intermittent basis, primarily during the day and evening hours and less frequently during the nighttime hours. For a worst -case analysis, it was assumed that the HVAC units would operate at maximum capacity during the daytime and nighttime hours.

Modeled receivers and the locations of the HVAC units are shown in Figure 7. Modeled data is included in Attachment 7. Future projected noise levels are summarized in Table 12.

6.0 Conclusions

6.1 Construction Noise
As shown in Table 9, construction noise levels would range from 56 to 73 dB(A) Leq at the adjacent property lines. The City’s Municipal Code does not place noise limit restrictions on construction activities, however, other jurisdictions commonly apply a noise level limit of 75 dB(A) L eq at residential
uses. Construction activities would generally occur over the period between 7:00 a.m. and 6:00 p.m. on weekdays. Although the existing adjacent uses would be exposed to construction noise levels that may be heard above ambient conditions, the exposure would be temporary and would not exceed 75 dB(A) L
eq. As construction activities associated with the project would comply with the time limits established in Section 10.24.020 (b)(9) of the City Municipal Code, temporary increases in noise levels from construction activities would be less than significant.

6.2 Traffic Noise

6.2.1 On-site Traffic and Rail Noise
The main source of noise at the project site is vehicle traffic on South Santa Fe Avenue and North Las Flores Drive as well as Sprinters on the adjacent rail line . The exterior noise level standard for multi-family uses is 65 CNEL. This standard is applicable at exterior use areas which include second- and third-floor balconies, rooftop decks, and the five proposed amenity areas consisting of active play areas and passive gathering areas . As shown in Table 10 , without consideration of any noise barriers, exterior noise levels are projected to range from 42 to 70 CNEL at the building façades and amenity area. Noise levels would be compatible with the City’s exterior multi-family noise level standard of 65 CNEL at all locations except the amenity area on the south side of Building 1 (Amenity Area A, Receiver 1) and the south and east sides of Building 1 facing the roadways (Receivers 8 and 9). In order to reduce noise levels at these locations, the project would include a 6-foot barrier adjacent to the amenity area south of Building 1, and a solid 3.5-foot barrier on the balconies located on the south and east sides of Building 1 and on the south and east sides of the Building 1 roof deck.

With construction of these barriers, exterior noise levels would be reduced to less than 65 CNEL and exterior noise impacts would be less than significant.

The interior noise level standard is 45 CNEL. Interior noise levels can be reduced through standard construction techniques. When windows are closed, standard construction techniques provide various exterior-to-interior noise level reductions depending on the type of structure and window.

Standard light-frame construction would reduce exterior to interior noise levels by at least 20 dB (FHWA 2011). With the installation of windows with an STC rating of 25 or higher, interior noise levels within the units in Building 1 would be reduced to 45 CNEL and interior noise levels would be less than significant. Interior noise levels at all other buildings would be 45 CNEL with standard light frame construction and without consideration of specific building components.

6.2.2 Off-site Traffic Noise
The additional vehicle trips associated with the project would increase noise levels on nearby roadways. A noise increase of 3 dB or more would be considered significant because 3 dB is the level at which an increase in noise is perceptible to a person. As shown in Table 11, the project would not result in a direct or cumulative noise increase of more than 3 dB. Therefore, the project would result in less than significant direct and cumulative impact related to traffic noise.

6.3 On-site Generated Noise
The noise sources on the project site after completion of construction are anticipated to be those that would be typical of any residential use, such as vehicles arriving and leaving, children at play, and landscape maintenance machinery. None of these noise sources are anticipated to violate the City Municipal Code. Rooftop HVAC noise levels were modeled at the adjacent properties. As shown in Table 12, HVAC noise levels would range from 33 to 42 dB(A) Leq. Noise levels would not exceed the applicable Noise Ordinance limits at the property lines.
