The results of that survey, as well as predicted future sound levels at the site, are presented in this letter report. • INTRODUCTION AND DEFINITIONS Existing Site Characterization The proposed project is located within the southeast portion of the City of Carlsbad. The physical address of the project site is 2311 Camino Hills Drive. The development site consists of approximately 10 acres and consists of undeveloped open space. El Camino Real bound the project site to the northeast and Camino Hills Drive to the northwest. El Camino Real provides regional access to the project area from Interstate 8 (1-8) to the west and State Route 78 (SR-78) to the north. A regional map of the proposed project site can be seen in Figure 1 on the following page. A vicinity map of the project area and surrounding community is shown in Figure 2 on page 3 of this report. The project site is classified as RLM -(Residential-Low Medium Density) within the City's General Plan. The topography of the site is characterized by slightly sloping hillside terrain bordered on the southeast and southwest by abruptly elevated slopes. Elevations on site range between 84 to 168 feet MSL (Mean Sea Level) across the entire project area. . ~ .~ Mr. James Boeker Pasco Engineering, Inc.

Tabata TPM Residential Development-Carlsbad CA ISE Report #06-021 July 26, 2007 (Revised} Page 5 of 23 Acoustical Definitions Sound waves are linear mechanical waves. They can be propagated in solids, liquids, and gases. The material transmitting such a wave oscillates in the direction of propagation of the wave itself. Sound waves originate from some sort of vibrc.ting surface. Whether this surface is the vibrating string of a violin or a person's vocal cords, a vibrating column of air from an organ or clarinet, or a vibrating panel from a loudspeaker, drum, or aircraft, the sound waves generated are all similar. All of these vibrating elements alternatively compress the surrounding air on a forward movement and expand it on a backward movement. There is a large range of frequencies within which linear waves can be generated, sound waves being confined to the frequency range that can stimulate the auditory organs to the sensation of hearing. For humans this range is from about 20 Hertz (Hz or cycles per second) to about 20,000 Hz. The air transmits these frequency disturbances outward from the source of the wave. Sound waves, if unimpeded, will spread out in all directions from a source. Upon entering the auditory organs, these waves produce the sensation of sound. Waveforms that are approximately periodic or c0nsist of a small number of periodic components can give rise to a pleasant sensation (assuming the intensity is not too high), for example, as in a musical composition. Noise, on the other hand, can be represented as a superposition of periodic waves with a large number of components and is generally defined as unwanted or annoying sound that is typically associated with human activity and which interferes with or disrupts normal activities. Although exposure to high noise levels has been demonstrated to cause hearing loss, the principal human response to environmental noise is annoyance. The response of individuals to similar noise events is diverse and influenced by the type of noise, the perceived importance of the noise and its appropriateness in the setting, the time of day, and the sensitivity of the individual hearing the sound. Airborne sound is a rapid fluctuation of air pressure above and below atmospheric levels. The loudest sounds the human ear can hear conformably are approximately one trillion times the acoustic energy that the ear can barely detect. Because of this vast range, any attempt to represent the acoustic intensity of a particular sound on a linear scale becomes unwieldy. As a result, a logarithmic ratio originally conceived for radio work known as the decibel (dB) is commonly employed. A sound level of zero "0" dB is scaled such that it is defined as the threshold of human hearing and would be barely audible to a human of normal hearing under extremely quiet listening conditions. Such conditions can only be generated in anechoic or "dead rooms". Typically, the quietest environmental conditions (extreme rural areas with extensive shielding) yield sound levels of approximately 20 decibels. Normal speech has a sound level of approximately 60 dB. Sound levels above 120 dB roughly correspond to the threshold of pain. Mr. James Boeker Pasco Engineering, Inc.

Typically, the quietest environmental conditions (extreme rural areas with extensive shielding) yield sound levels of approximately 20 decibels. Normal speech has a sound level of approximately 60 dB. Sound levels above 120 dB roughly correspond to the threshold of pain. The minimum change in sound level that the human ear can detect is approximately 3 dB. A change in sound level of 10 dB is usually perceived by the average person as a doubling (or halving) of the sounds loudness. A change in sound level of 10 dB actually represents an approximately 90 percent change in the sound intensity, but only about a 50 percent change in the perceived loudness. This is due to the nonlinear response of the human ear to sound. As mentioned above, most of the sounds we hear in the environment do not consist of a single frequency, but rather a broad band of frequencies differing in sound level. The intensities of each frequency add to generate the sound we hear. The method commonly used to quantify environmental sounds consists of determining all of the frequencies of a sound according to a weighting system that reflects the nonlinear response characteristics of the human ear. This is called "A" weighting, and the decibel level measured is called the A-weighted sound level (or dBA). In practice, the level of a noise source is conveniently measured using a sound level meter that includes a filter corresponding to the dBA curve. Although the A-weighted sound level may adequately indicate the level of environmental noise at any instant in time, community noise levels vary continuously. Most environmental noise includes a conglomeration of sounds from distant sources that create a relatively steady background noise in which no particular source is identifiable. Mr. James Boeker Pasco Engineering, Inc. Tabata TPM Residential Development-Carlsbad CA ISE Report #06-021 July 26, 2007 (Revised) Page 7 of 23 For this type of noise, a single descriptor called the Leq (or equivalent sound level) is used. Leq is the energy-mean A-weighted sound level during a measured time interval. It is the 'equivalent' constant sound level that would have to be produced by a given source to equal the average of the fluctuating level measured. For most acoustical studies, the monitoring interval is generally taken as one-hour and is abbreviated Leq-h. To describe the time-varying character of environmental noise, the statistical noise descriptors L 10, LSO, and L90 are commonly used. They are the noise levels equaled or exceeded during 1 0 percent, 50 percent, and 90 percent of a stated time. Sound levels associated with the L 10 typically describe transient or short-term events, while levels associated with the L90 describe the steady state (or most prevalent) noise conditions. In addition, it is often desirable to know the acoustic range of the noise source being measured. This is accomplished through the maximum and minimum measured sound level (Lmax and Lmin) indicators. The Lmin value obtained for a particular monitoring location is often called the acoustic floor for that location. Finally, a sound measure employed by the State of California (and adopted by the City of Carlsbad) is known as the Community Noise Equivalence Level (or CNEL) is defined as the "A" weighted average sound level for a 24-hour day. It is calculated by adding a 5-decibel penalty to sound levels in the evening (7:00 p.m. to 10:00 p.m.), and a 1 0-decibel penalty to s':>und levels in the night (1 0:00p.m. to 7:00a.m.) to compensate for the increased sensitivity to noise during the quieter evening and nighttime hours. • APPLICABLE SIGNIFICANCE CRITERIA City of Carlsbaj The Noise Element of the City of Carlsbad identifies sound levels that are compatible with various land uses. According to the City of Carlsbad Draft Noise Guidelines Manual, sound levels up to 60 dBA CNEL are compatible with residential land uses. Sound levels up to 65 dBA CNEL are compatible with recreational areas such as parks and playgrounds. The City also requires an interior noise study (compliant with State of California CCR Title 24 standards) where exterior exposure is in excess of the above land use criteria. State of California CCR Title 24 The California Code of Regulations (CCR), Title 24, Noise Insulation Standards, states that multi-family dwellings, hotels, and motels located where the CNEL exceeds 60 dBA, must obtain an acoustical analysis showing that the proposed design will limit interior noise to less than 45 dBA CNEL. Interior noise standards are typically applied to sensitive areas within the structure where low noise levels are desirable (such as living rooms, dining rooms, bedrooms, and dens or studies). Worst-case noise levels, either existing or future, must be used for this determination. Future noise levels must be predicted at least ten years from the time of Mr. James Boeker Pasco Engineering, Inc. Tabata TPM Residential Development-Carlsbad CA ISE Report #06-021 July 26, 2007 (Revised) Page 8 of 23 building permit application. The City of Carlsbad has adopted the CCR Title 24 standards. Thus, for the purposes of analysis , the applicable exterior noise design threshold is 60 dBA CNEL. The applicable interior noise standard is 45 dBA CNEL. • ANALYSIS METHODOLOGY Existing Conditions Field Survey A Quest Model 2900 ANSI Type 2 integrating sound level meter was used as the data collection device. The meter was mounted to a tripod five-foot above ground level in order to simulate the noise exposure of an average-height human being. Two short-term sound level measurements were taken on the proposed site. The meter was placed on the northeastern portion of the site near El Camino Real (see ML 1 in Figure 4a) and the northwest portion near Camino Hills Drive (see ML2 in Figure 4b). This was done in order to obtain an estimate of the worst-case existing onsite noise levels during normal traffic conditions. All monitoring sites were spatially logged using a geographic positioning system. FIGURES 4a through -c: Monitoring Locations-Tabata Residential Development (ISE, 3/06) Mr. James Boeker Pasco Engineering, Inc. Tabata TPM Residential Development-Carlsbad CA ISE Report #06-021 July 26, 2007 (Revised) Page 9 of 23 The measurements were performed on March 15, 2006 starting at approximately 3:00 p.m. All equipment was calibrated before testing at ISE's acoustics and vibration labon ... tory to verify conformance with ANSI S1-4 1983 Type 2 and IEC 651 Type 2 standards. Traffic Noise Impact Assessment Approach The Caltrans Sound 32 Traffic Noise Prediction Model with California (CALVENO) noise emission factors (based on FHWA RD-77-108 and FHWA/CA/TL- 87/03 standards) were used to calculate future onsite vehicular traffic noise levels. The Sound 32 model was calibrated in accordance with Appendix E of the FHWA Highway Traffic Noise Prediction Manual (Report RD-77-1 08) for a normalized Level of Service of 'C'. This is also in accordance with Caltrans Technical Noise Supplement (TeNS) sections N-5440 & N-5460 published October 1998. Model input included: o A digitized representation of all major roadways (i.e., El Camino Real) o Future Average Daily Trips (ADTs) for nearby major roadways (Source: County of San Diego, 3/06) o 96/2/2 (automobiles/medium/heavy vehicles) traffic mix o Topography as identified in the project site plans (Source: Pasco Engineering, 2006) Receptor elevations were considered five feet above the appropriate floor (pad) elevation and were taken near the center of each proposed lot. Second floor receptor areas were modeled at 15 feet above the respective pad elevation. The receptor locations can be seen in Figure 5 on Page 10 of this report. • FINDINGS I RECOMMENDATIONS Ambient Sound Measurement Results Testing conditions during the monitoring period were sunny and hazy with an average barometric pressure reading of 30.01 in-Hg, an average northwesterly wind speed of 4 to 8 miles per hour (MPH), and an approximate mean temperature of 70 degrees Fahrenheit. The results of the one-hour sound level monitoring are shown below in Table 1. The values for the energy equivalent sound level (Leq), the maximum and minimum measured sound levels (Lmax and Lmin), and the statistical indicators L 10, L50, and L90, are given for each monitoring location. Noise levels on site were found to be consistent with the observed community setting and topography. The value for the equivalent sound level (Leq-h) within the project site was found to range between approximately 58 and 67 dBA. Background noise levels (i.e., L90 levels) were found to be lower than the energy equivalent counterpart (e.g., Leq-h) indicating the cyclical traffic patterns along El Camino Real. The acoustic floor for the site, as indicated by the Lmin metric, was found to range from approximately 42 to 50 dBA. Mr. James Boeker Pasco Engineering, Inc.

Tabata TPM Residential Development-Carlsbad CA ISE Report #06-021 July 26, 2007 (Revised) Page 11 of23 Future Traffic Noise Impacts The primary source of future traffic noise near the project site would be from El Camino Real. Future traffic estimates for this roadway predict volumes as high as 38,000 ADT (Source: SANDAG Series 10-2030 Enhanced Traffic Prediction Model, 4106). The future speed limit along this roadway is projected to be 55 MPH. Peak hour traffic values are calculated for a 1 0% traffic flow pattern and a 96/2/2 (automobiles/medium/heavy vehicles) percent mix in accordance with Caltrans traffic forecasting practices and the observed traffic distribution. For peak hour traffic percentages between approximately 8 and 12 percent, the energy-mean A-weighted sound level is equivalent to the Community Noise Equivalent Level (CNEL). Outside this range, a maximum variance of up to two dBA occurs between Leq-h and CNEL. The results of the acoustical modeling are shown below in Table 2 for a representative sampling of lots within the proposed development area. For each receptor examined, both the unmitigated ground floor areas and the second floor fa9ade noise levels are provided. Based on the model results, no lots would exceed the City's noise abatement thresholds. Thus, no exterior mitigation will be necessary. These findings are based upon the project grading plan as submitted to ISE (Pasco, 2006) and include the project proposed berm adjacent to El Camino Real. Should the project grading plan (as analyzed within this report) change, then a revised noise assessment would be necessary.

This area would exceed the CCR Title 24 noise abatement threshold of 60 dBA duG to the predicted future traffic activity and would require structural mitigation of the residential building (i.e., specialized door and window treatments) to comply. Prior to issuance of building permits for the proposed project, an interior noise analysis compliant with the California Code of Regulations (CCR), Title 24, Noise Insulation Standards would be required. The acoustical analysis should demonstrate that the proposed architectural design would limit interior noise to 45 dBA CNEL or less. Worst-case noise levels, either existing or future, must be used for this determination.
