Exposure to high noise levels has been demonstrated to cause hearing loss. The individual human response to environmental noise is based on the sensitivity of that individual, the type of noise that occurs and when the noise occurs. Sound is measured on a logarithmic scale consisting of sound pressure levels known as a decibel (dB). The sounds heard by humans typically do not consist of a single frequency but of a broadband of frequencies having different sound pressure levels. The method for evaluating all the frequencies of the sound is to apply an A -weighting to reflect .how the human ear responds to the different sound levels at different frequencies. The A -weighted sound level adequately describes the instantaneous noise whereas the equivalent sound level depicted as Leq represents a steady sound level containing the same total acoustical energy as the actual fluctuating sound level over a given time interval. The Community Noise Equivalent Level (CNEL) is the 24 hour A -weighted average for sound, with corrections for evening and nighttime hours. The corrections require an addition of 5 decibels to sound levels in the evening hours between 7 p.m. and 10 p.m. and an addition of 10 decibels to sound levels at nighttime hours between 10 p.m. and 7 a.m. These additions are made to account for the increased sensitivity during the evening and nighttime hours when sound appears louder. CNEL values do not represent the actual sound level heard at any particular time, but rather represents the total sound exposure. Additionally, Sound Transmission Class (or STC) is an integer rating of how well airborne sound is attenuated by a building partition. STC is widely used to rate interior partitions, ceilings/floors, doors, windows and exterior wall configurations (see ASTM International Classification E413 and E90). The STC number is derived from tested sound attenuation values found at the 1/3 octave band frequencies. These transmission -loss (TL) values are then plotted and compared to a standard reference contour. Acoustical engineers fit these values to the appropriate TL Curve to determine a single STC value found at 500 Hertz. STC is roughly the decibel reduction in noise a partition can provide, abbreviated 'dB'. If an 85 dB sound on one side of a wall is reduced to 50 dB on the other side, that partition is said to have an STC of 35. This number does not apply across the range of frequencies because the STC value is derived from a curve -fit from the tested 1/3 octave band frequencies. Any partition will have less TL at lower frequencies.

INTERIOR NOISE STANDARDS California's Title 24 Noise Standards In 1974, the California Commission on. Housing and Community Development adopted noise insulation standards for multi -family residential buildings (Title 24, Part 2, California Code of Regulations or CCR). CCR Title 24 establishes standards, based on the U.S. Department of Housing and Urban Development (HUD) requirements, for interior room noise (attributable to outside noise sources). The regulations also specify that acoustical studies must be prepared whenever a multi -family residential or motel/hotel building or structure is proposed to be located near an existing or adopted freeway route, expressway, parkway, major street, thoroughfare, rail line, rapid transit line, or industrial noise source, and where such noise sources create an exterior CNEL (or Ldn) of 60 dBA or greater. Such acoustical analysis must demonstrate that the residence has been designed to limit intruding noise to an interior CNEL (or Ldn) of at least 45 dBA. City of La Quinta Noise Standards The City of La Quinta has adopted interior and exterior noise standards as part of the General Plan Noise Element for assessing the compatibility of land uses with transportation related noise impacts. For noise sensitive residential land uses, the City has adopted an exterior noise level goal of 65 dBA CNEL for the outdoor living areas and requires an interior noise level of less than 45 dBA CNEL. In the context of this noise analysis, the noise impacts associated with the project are controlled by the City noise element. ANALYSIS PROCEDURES Exterior Noise Levels The primary source of noise impacts to the project site will be vehicular noise from adjacent PGA Boulevard. Based on the future traffic projections along these roadways, portions of the site will experience worst -case unmitigated exterior noise levels as high as 64 dBA CNEL for the building facades (Source: Eden Rock at PGA West Noise Assessment — Impact Sciences dated November 2007). This worst -case noise level of 64 dBA CNEL was utilized for all proposed residential dwelling units. 4/24/2014 5 13112-02 PGA West Interior Noise Mr. Mike Lake L489 im California West Communities 44G Gresteourt Lane, FallbrooK GA f.=s 5927 Priestly Drive, Ste. 103 phone 7Go-473-120 Carlsbad, CA 92008 Fax 7Go-Gsf-4f43 Interior Noise Levels The methodology used to determine the resultant interior noise levels is based upon the exterior noise level minus the sound transmission loss as identified in the American Society of Testing and Materials (ASTM) guidelines: E413 U90. Standard building construction will provide a noise reduction of approximately 12-15 dBA with a windows open conditions and minimum 20 dBA noise reduction with the windows closed. The exterior noise levels at the proposed structures calculated in terms of dBA are converted to the six octave band sound pressure levels between: 125 Hertz - 4000 Hertz. Acoustical modeling of the proposed project dwelling units was performed in accordance with the above guidelines and included combining the transmission loss for each of the building components that will reduce the interior noise levels. Building components typically include the windows, exterior doors, and exterior walls. The total noise reduction is dependent upon the transmission loss of each building component, their subsequent surface area, quality of the building/construction materials, a building fagade and angle correction. The interior noise level is also dependent on the acoustical energy absorbed within the room based upon the Noise Reduction Coefficients (NRC). NRC is a scalar representation of the amount of sound energy absorbed upon striking a particular surface and the arithmetic value average of sound absorption coefficients indicating a material's ability to absorb sound. The absorption coefficients for individual surface areas such as carpet, drywall and furnishings are used to calculate the interior room effects. The calculated building noise reduction includes both the room absorption characteristics and the transmission loss from the exterior wall assembly. The interior noise reduction calculations were performed using Ldn's interior noise model. The model converts the exterior sound level to octave band frequencies and accounts for the transmission loss, correction factors and room absorption. The floor plans used for this analysis were provided by Bassenian Lagoni Architects dated April, 2014. The following construction details were utilized for each of the building assemblies to determine the noise reduction characteristics: Exterior walls and roof assemblies must have a Sound Transmission Class (STC) rating of 46 or better. Exterior walls with this rating consist of 2"x 4" studs or larger, spaced 16" o.c. with R-13 insulation minimum and an exterior surface of 7/8" cement plaster (stucco). Interior wall and ceiling surfaces shall be at least 1/2" thick gypsum or plaster. Roof assemblies should have a minimum of 1/2" sheathing, R-19 insulation and sealed to prevent noise leaks. Exterior entry doors should be of solid core construction having a minimum STC rating of 26.

The window assemblies are generally the weakest noise reducing component but are the most convenient and cost effective elements to change if additional attenuation is needed. The STC ratings for the glass assemblies was calculated in the interior noise model and provided in the findings below. Bathrooms, kitchens, closets and corridors are not required to meet the 45 dBA CNEL standard and therefore were not modeled. All living areas where lower noise levels are essential for conversation and sleep should have carpeting installed; this includes bedrooms, living rooms and dining rooms. These rooms and were modeled to determine the interior noise reductions. If the modeled interior noise levels were found to be higher than 45 dBA CNEL in the living areas with the minimum assembly requirements described above additional modeling was performed to determine the minimum STC rating for the glass assemblies to further reduce interior noise levels below the acceptable interior threshold of 45 dBA CNEL. FINDINGS The worst -case exterior noise levels were determined to be 64 dBA CNEL. Basic calculations show that a windows open condition will only reduce the interior noise levels 12-15 dBA CNEL and not provide adequate interior noise mitigation. To meet the 45 dBA CNEL interior noise standard, an overall minimum interior noise level reduction of 19 dBA CNEL is needed for the proposed project. Therefore a closed window condition is required to reduce interior noise levels to comply with CCR Title 24 and City of La Quinta requirements. The windows closed condition requires that mechanical ventilation is installed to move air within the structure and control temperatures. The mechanical ventilation must meet the jurisdictional requirements for these dwelling units. The worst case building fagade noise level was calculated to be 64 dBA CNEL. The necessary Sound Transmission Class (STC) ratings and transmission losses for all assemblies to reduce the interior noise levels at or below the 45 dBA CNEL standard are provided in Table 1 on the following page. Each sensitive room for all twenty proposed floor plans was modeled. The modeled results are provided as an attachment to this report. 4/24/2014 7 13112-02 PGA West Interior Noise Mr. Mike Lake California West Communities 5927 Priestly Drive, Ste. 103 Carlsbad, CA 92008 LAv l dff#v$ Imo. 444 Gresteourt Lane, FallbrooK GA f2028 phone 7Go-4V-1257 Fax 7Go-w-4943 Table 1: Sound Transmission Class Ratings Assembly STC Octave Band Transmission Loss (Hz) Windows 26 21 17 25 32 37 38 Fixed Window 26 17 16 22 31 35 27 Glass Doors 26 16 19 22 30 31 28 Exterior Door 26 16 14 23 30 36 26 STC Ratings used in Mode/ Interior noise levels will be at or below 45 dBA CNEL and no noise impacts are anticipated and no additional noise reductions are required for any units of the PGA West residential project with the incorporation of the STC ratings provided in Table 1.
