Recommended Products 1.0 EXECUTIVE SUMMARY The proposed project, Tamarack Beach Homes, consists of the demolition of an existing building and construction of a new residential complex consisting of five (5) detached single-family dwelling units. The project site is located at 438 Tamarack Avenue in the City of Carlsbad, California. The current and future noise environment primarily consists of traffic noise from Tamarack Avenue and Interstate 5, and railway noise from the track system located to the west of the project site. As per City of Carlsbad requirements, noise levels at outdoor use areas of the residential uses should be 60 CNEL or less. For the proposed residential units, a minimum of 60 square feet of private recreation space must be provided per unit. Future combined noise impacts were calculated at private outdoor use areas to determine compliance with this requirement. It was determined that, with the currently proposed configuration of the project site, each unit will include the minimum 60 square feet of private recreation space that is protected from noise impacts exceeding 60 CNEL. For this reason, no mitigation is required for the attenuation of exterior noise impacts to the project site. A brief evaluation of ground-borne vibration impacts to the project site from the nearby rail line has also been conducted. It has been determined that the project will be exposed to vibration impacts that fall below the applicable thresholds established within the FTA Transit Noise and Vibration Assessment document. No mitigation is deemed necessary for the attenuation of vibration impacts at the project site. The City of Carlsbad and State of California require interior noise levels not exceeding 45 CNEL in residential habitable space. Contemporary exterior building construction is expected to achieve at least 15 decibels of exterior-to-interior noise attenuation with windows opened. Exterior noise levels at many proposed building facades are shown to exceed 60 CNEL. Due to high exterior noise levels at building facades, an exterior-to-interior analysis was performed to determine building features necessary for interior noise levels in residential habitable units not to exceed 45 CNEL, as required by the State of California and the City of Carlsbad. Calculations show that with typical exterior wall assemblies, all windows and glass doors of residential units should have a minimum rating of STC 28, and mechanical ventilation should be provided in residential units. With these project design features in place, interior noise levels are expected to comply with the regulations of the City of Carlsbad and the State of California. Project-generated noise impacts from the site to off-site receivers have been addressed. HVAC noise is expected to be adequately controlled at off-site receivers based on distance attenuation anticipated for typical air conditioning units. The City of Carlsbad Municipal Code does not provide noise limits for temporary construction activity at surrounding noise-sensitive property lines; however, the hours during which construction activity can take place are limited by Section 8.48.010 of the code. According to this section of the code, construction activity may not take place between the hours of 6 p.m. and 7 a.m., Monday through Friday, and between 6 p.m. and 8 a.m. on Saturday. The contractor can limit noise impacts at surrounding noise-sensitive receivers by adhering to the permissible hours of operation and following general good practice measures, including reasonable maintenance of equipment, conservative planning of simultaneous equipment operation, and using equipment with effective mufflers. The proposed project is not expected to result in any significant noise impacts, by the standards of the California Environmental Quality Act (CEQA). Noise impacts to and from the project site are summarized in Section 5.4. Eilar Associates, Inc. Job #B71107N1 December 28, 2017 Page 1 2.0 INTRODUCTION This acoustical analysis report is submitted to satisfy the acoustical requirements of the City of Carlsbad for tentative tract map (CT), planned development, and coastal development permit approvals. This analysis addresses noise impacts from roadway traffic and the nearby rail line to determine project features necessary to achieve compliance with the City of Carlsbad noise regulations, which require exterior noise levels of 60 CNEL or less at outdoor use areas, and interior noise levels of 45 CNEL or less in residential spaces. Noise impacts to off-site receivers are also addressed. All noise level or sound level values presented herein are expressed in terms of decibels, with A-weighting to approximate the hearing sensitivity of humans. Time-averaged noise levels are expressed by the symbol Lea, for a specified duration. The Community Noise Equivalent Level (CNEL) is a calculated 24-hour weighted average, where sound levels during evening hours of 7 p.m. to 10 p.m. have an added 5 dB weighting, and sound levels during nighttime hours of 10 p.m. to 7 a.m. have an added 10 dB weighting. This is similar to the Day-Night sound level, DNL, which is a 24-hour average with an added 10 dB weighting on the same nighttime hours but no added weighting on the evening hours. Sound levels expressed in CNEL are always based on A-weighted decibels. As DNL and CNEL are generally found to be within approximately 0.5 dB of one another, DNL values have been considered equivalent to CNEL for purposes of this analysis. These metrics are used to express noise levels for both measurement and municipal regulations, for land use guidelines, and for enforcement of noise ordinances. Further explanation can be provided upon request. 2.1 Project Description The proposed project, Tamarack Beach Homes, consists of the demolition of an existing building and construction of a new residential complex consisting of five (5) detached single family dwelling units. The dwelling units will be either two-story with a roof deck or three-story, and each will have an attached two-car garage. The amount of habitable space provided for each unit will range from 2,385 to 2,534 square feet. For additional information, please refer to project plans provided in Appendix A. 2.2 Project Location The project site is located at 438 Tamarack Avenue in the City of Carlsbad, California. The Assessor's Parcel Number (APN) for the property is 204-280-23-00. The project location is shown on the Vicinity Map, Figure 1, following this report. An Assessor's Parcel Map, Satellite Aerial Photograph, and Topographic Map are also provided as Figures 2 through 4, respectively. 2.3 Applicable Noise Standards This acoustical analysis report is submitted to satisfy the acoustical requirements of the City Carlsbad Noise Guidelines Manual, Noise Element to the General Plan, and Municipal Code. The City of Carlsbad Noise Guidelines Manual requires that at a residential property, indoor noise levels are attenuated to 45 CNEL for residential space, and noise levels at residential outdoor use areas do not exceed 60 CNEL. For the proposed residential units, a minimum of 60 square feet of private recreation space must be provided per unit. Although not referenced within the Noise Guidelines Manual, the City of Carlsbad has also requested that, due to the site's proximity to the railway tracks, ground-borne vibration impacts to Eilar Associates, Inc. Job #B71107N1 December 28, 2017 Page 2 ' the project site be addressed to ensure compliance with typically accepted standards. Please refer to Section 4.1.4 for additional information on the railway vibration analysis. The Noise Element to the General Plan gives noise limits for non-transportation sources as measured at the property lines ·of nearby noise-sensitive properties, such as residential land uses. Noise impacts generated at the project site must adhere to the noise limits of 55 dBA between the hours of 7 a.m. to 10 p.m., and 45 dBA between the hours of 10 p.m. to 7 a.m. at adjacent residential property lines. In addition, Section 8.48.010 of the City of Carlsbad Municipal Code states that construction activity is prohibited between the hours of 6 p.m. and 7 a.m., Monday through Friday, and between 6 p.m. and 8 a.m. on Saturday. Please refer to Appendix B for pertinent sections of the City of Carlsbad Noise Guidelines Manual, Noise Element to the General Plan, and Municipal Code. 3.0 ENVIRONMENTAL SETTING 3.1 Existing Noise Environment The primary noise sources in the vicinity of the project site are traffic noise from Tamarack Avenue and Interstate 5, and railway noise from the track system located to the west of the project site. No other noise source is considered significant. 3.1.1 Railway Noise Sources The overall noise environment at the project site is influenced by train traffic traveling on a line located to the west of the project site. The centerline of the tracks is located approximately 220 feet from the western property line of the site. Based on the current schedules for Amtrak and Coaster, approximately 49 passenger trains pass the site each day. Scheduling information was not available for BNSF freight trains, but from prior experience with projects along this rail corridor, typical freight traffic includes approximately four to six freight trips per day. Calculations were performed using the CREATE Freight Noise and Vibration Model (see reference) to determine the noise impacts from train traffic on the project site. With the current peak volume of four passenger trains and one freight train passing the site per hour during the daytime hours, and one passenger train and one freight train passing the site per hour during the nighttime hours, the railway noise level was calculated to be approximately 68 CNEL at the western property line of the project site, without considering any shielding provided by intervening structures. With shielding taken into account, the noise impact at the west property line (near the southwest corner of the project site) is expected to drop to approximately 64 CNEL. Railway noise contours considering intervening structures were calculated for the site, and it was determined that noise impacts would range from approximately 59 CNEL to 64 CNEL at the site. Detailed calculations of railway noise have been performed for the determination of combined noise impacts at outdoor use areas and building facades, and are addressed in Section 5.1 of this report. Railway noise contours are shown graphically in Figure 5. Please refer to Appendix C for additional information. Eilar Associates, Inc. Job #871107N1 December 28, 2017 Page 3 3.1.2 Roadway Traffic Noise ' Current (2008) and future (2035) traffic volumes are given based on information from the San Diego Association of Governments (SANDAG) Series 12 Transportation Forecast Information Center, and additional information has been obtained from the Caltrans Traffic Census (see reference). Tamarack Avenue is a two-lane, two-way Collector running east-west to the south of the project site. The posted speed limit is 30 mph. According to SANDAG, the current traffic volume on Tamarack Avenue is 10,800 Average Daily Trips (ADT). Interstate 5 (1-5) is an eight-lane, two-way Freeway running north-south to the east of the project site. The posted speed limit is 65 mph. According to SAN DAG, the current traffic volume ·on 1-5 is 91 ,200 ADT traveling northbound and 87,300 ADT traveling southbound. Traffic composition information for Interstate 5 was provided by the Caltrans Traffic Census. The truck percentage mix of 1.9% medium trucks and 2.9% heavy trucks was applied to this roadway. No current or future truck percentages were available for Tamarack Avenue; however, based on neighboring and surrounding land use, roadway classification, professional experience and on-site observations, a truck percentage mix of 1.0% medium and 0.5% heavy trucks was used for Tamarack Avenue. Traffic volumes for the roadway sections near the project site are shown in Table 1. For further roadway details and projected future ADT traffic volumes, please refer to Appendix D: Traffic Noise Model (TNM) Data and Results. Table 1. Overall Roadway Traffic Information Speed Vehicle Mix(%) Current ADT Future ADT Roadway Name Limit Medium Heavy (2008) (2035) (mph) Trucks Trucks Tamarack Avenue 30 1.0% 0.5% 10,800 13,800 Interstate 5 Northbound 65 1.9% 2.9% 91 ,200 120,900 Interstate 5 Southbound 65 1.9% 2.9% 87,300 116,300 Without existing or proposed project structures, the current traffic noise contours calculated at ground level show that traffic noise impacts to the project site are between 63 and 66 CNEL. Combined railway and traffic noise levels are detailed in Section 5.0. For a graphical representation of traffic noise contours, please refer to Figure 6: Site Plan Showing Current Traffic CNEL Contours and Noise Measurement Location. 3.1.3 Measured Noise Level An on-site inspection and traffic noise measurement was made on the evening of November 13, 2017. The noise measurement was made using the methodology described in Section 4.1, near the southwest corner of the project site and approximately 25 feet from the Tamarack Avenue centerline. The microphone position was placed approximately five feet above the site grade. Traffic volumes for Tamarack Avenue were recorded for automobiles, medium-size trucks, and large trucks during the measurement period. After a 15-minute sound level measurement paused Eilar Associates, Inc. Job #871107N1 December 28, 2017 Page4 for extraneous (non-traffic) noise sources, there was no change in the LEa and results were then recorded. The measured noise level and related weather conditions are found in Table 2. Table 2. On-Site Noise Measurement Conditions and Results Date Monday, November 13, 2017 Time 5:55 p.m. -6:12 p.m. Conditions Cloudy skies, winds at 3-5 mph, temperature in the mid 60s with high humidity Measured Noise Level 66.1 dBA LEo 3.1.4 Calculated Noise Level Noise levels were calculated for the site using the methodology described in Section 4.1 for the location, conditions, and traffic volumes counted during the noise measurements. The calculated noise levels (LEO) were compared with the measured on-site noise level to determine if adjustments or corrections (calibration) should be applied to the traffic noise prediction model. Adjustments are intended to account for site-specific differences, such as reflection and absorption, which may be greater or lesser than accounted for in the model. The measured noise level of 66.1 dBA LEO near the southwest corner of the project site was compared to the calculated (modeled) noise level of 65.3 dBA LEa for the same conditions and traffic flow. According to the Federal Highway Administration's Highway Traffic Noise: Analysis and Abatement Guide (see reference), a traffic noise model is considered validated if the measured and calculated noise impacts differ by three decibels or less. No adjustment was deemed necessary to model future noise levels for this location as the difference between the measured and calculated levels was found to be less than three decibels. The Traffic Noise Model is assumed to be representative of actual traffic noise that is experienced on site. Please refer to Table 3 for further evaluation. Please refer to Appendix D: Traffic Noise Model (TNM) Data and Results for more information. Table 3. Calculated versus Measured Traffic Noise Data Location Calculated Measured Difference Correction 25 feet from Tamarack Ave CL 65.3 dBA LEO 66.1 dBA LEO 0.8 dB None Applied 3.2 Future Noise Environment The future on-site noise environment will be the result of the same traffic and railway noise sources. Future train noise is not expected to change significantly, and therefore, was modeled as described above. 3.2.1 Future Transportation Noise The traffic volume of Tamarack Avenue is expected to increase to 13,800 ADT by the year 2035. The traffic volume of Interstate 5 is expected to increase to 120,900 ADT traveling northbound and 116,300 ADT traveling southbound by the year 2035. Eilar Associates, Inc. Job #B71107N1 December 28, 2017 Page 5 The same truck percentages from the existing traffic volumes were used for future traffic volume modeling. The roadway classification, speed limit, and roadbed grade elevations are expected to remain the same. By the year 2035, Interstate 5 is expected to add four High-Occupancy Vehicle (HOV) lanes, with two lanes traveling in each direction. The additional traffic volume traveling in these lanes has been taken into account in the future traffic volumes listed above. For further roadway details and projected future ADT traffic volumes, please refer to Appendix D: Traffic Noise Model (TNM) Data and Results. Without existing or proposed project structures, the future traffic noise contours calculated at ground level show that future traffic noise impacts to the project site will increase slightly to be between 64 and 67 CNEL. Combined railway and traffic noise levels are detailed in Section 5.0. For a graphical representation of traffic noise contours, please refer to Figure 7: Site Plan Showing Future Traffic CNEL Contours and Noise Measurement Location . 3.2.2 Project-Generated Noise Sources The primary source of noise generated by the proposed project is anticipated to be HVAC equipment. A typical HVAC unit was selected that is assumed to be representative of a unit that could be used on site for each unit. The typical unit selected is manufactured by Carrier, and is model number 38HDR060 (5-ton capacity). Sound power levels have been provided by the manufacturer in octave band values and a sound rating value. The sound power level spectrum for the unit is shown below in Table 4. Table 4. Sound Power Levels of Carrier 38HDR060 (Typical 5-ton Unit) Sound Power at Octave Band Frequency (dBA) Total Source (dBA) 125 250 500 1K 2K 4K SK Carrier 38HDR060 63.0 61 .5 64.0 66.5 66.0 64.5 55.5 72 Although the City of Carlsbad Municipal Code does not have a specific noise limit for temporary construction activity, noise levels of this activity have been disclosed and are detailed in Section 5.3.2. Demolition and site preparation/grading are typically the activities which generate the highest noise levels, and therefore, these activities are the focus of this brief analysis. Table 5 below shows typical construction equipment noise levels for pieces of equipment anticipated to be used on site. Typical noise levels for these pieces of equipment have been provided by DEFRA (see reference). Table 5.

Job #871107N1 December 28, 2017 Page 6 • 4.0 METHODOLOGY AND EQUIPMENT I 4.1 Methodology 4.1.1 Field Measurement Typically, a "one-hour" equivalent sound level measurement (LEO, A-Weighted) is recorded for at least one noise-sensitive location on the site. During the on-site noise measurement, start and end times are recorded, vehicle counts are made for cars, medium trucks (double-tires/two axles), and heavy trucks (three or more axles) for the corresponding road segment(s). Supplemental sound measurements of one hour or less in duration are often made to further describe the noise environment of the site. For measurements of less than one hour in duration, the measurement time is long enough for a representative traffic volume to occur and the noise level (LEO) to stabilize. The vehicle counts are then converted to one-hour equivalent volumes by using the appropriate multiplier. Other field data gathered includes measuring or estimating distances, angles-of-view, slopes, elevations, roadway grades, and vehicle speeds. This data is checked against the available maps and records. 4.1.2 Roadway Noise Calculation The Traffic Noise Model, Version 2.5 program released by the U.S. Department of Transportation is used for calculating the current future daytime average hourly noise level (HNL) contours at the project site, taking into account surrounding buildings, elevation, and additional topography. The daytime average hourly traffic volume is calculated as 0.058 times the ADT, based on the studies made by Wyle Laboratories (see reference). The HNL is equivalent to the hourly LEO, and both are converted to the CNEL by adding 2.0 decibels, as shown in the Wyle Study. Future CNEL is calculated for desired receptor locations using future road alignment, elevations, lane configurations, projected traffic volumes, estimated truck mixes, and vehicle speeds. -Noise attenuation methods may be analyzed, tested, and planned with TNM, as required. In order to determine the estimated traffic volumes of roadways during the traffic noise measurement made on site for model calibration, the approximate percentage of the Average Daily Trips (ADT) value for the time period in which the measurement is made is incorporated into the traffic model. These percentages have been established in a study performed by Katz-Okitsu and Associates, Traffic Engineers (see reference). For purposes of calibrating the TNM, 6.1 % of the ADT values for the current environment were used in calculations to account for traffic on surrounding roadways between the hours of 6 p.m. and 7 p.m. in the vicinity of the project site. Further explanation can be supplied on request. 4.1.3 Railway Noise Calculation The railway noise analysis is accomplished using CREATE noise model and Cadna Version 2018 (see references). CREATE performs the evaluation of a site's exposure to railway noise by taking into account factors such as the distance from the site to the railroad track centerline, the number of diesel trains in both directions during an average 24-hour day, the fraction of trains that operate during the night, the average number of diesel locomotives, the average length of each train, the average train speed past the site, the rail types, and whether the site is nearby crossings where train whistles or horns are sounded. Results from CREATE are given at a single point, and therefore, Cadna is used in order to calculate noise impacts over the entire project site. Cadna Eilar Associates, Inc. Job #871107N1 December 28, 2017 Page 7 (Computer Aided Noise Abatement) is a model-based computer program developed by DataKustik for predicting noise impacts in a wide variety of conditions. Cadna assists in the calculation, presentation, assessment, and mitigation of noise exposure. It allows for the input of project information such as noise source data, barriers, structures, and topography to create a detailed model and uses the most up-to-date calculation standards to predict outdoor noise impacts. 4.1.4 Ground-Borne Vibration Impacts Residential areas located in the vicinity of rai lroad tracks, such as the proposed project site, may be subject to not only train noise, but also to ground-borne vibration. The Federal Transit Administration publication Transit Noise and Vibration Assessment (see reference) details the effects of ground-borne vibration on structures and its effect on humans. According to th is publication, ground-borne vibration consists of the movement of floors, rattling of windows, shaking of items on shelves or hanging on wall, and rumbling sounds. Vibration energy can travel through the tracks and into the ground where the vibration waves can travel. The effects of ground-borne vibration as perceived by humans are most commonly experienced indoors, as the reaction of the structure to the vibration is more easily detected than if the vibrations were felt outdoors. Ground-borne vibration can be quantified as vibration velocity level in decibels. The most typical reference quantity used for U.S. measurements is 1 micro-inch/second. The aforementioned FTA publication details the criteria for determining the significance of vibration noise impacts, and offers the maximum acceptable vibration levels (in VdB ref. 1 micro- inch/second) for various land uses. For residential land use, the maximum acceptable vibration level is 72 VdB for "Frequent Events," which is defined as more than 70 events per day, and 80 VdB for "Infrequent Events," which is fewer than 70 events per day. 4.1 .5 Exterior-to-Interior Noise Analysis The City of Carlsbad and the State of California requires residential buildings to be designed to attenuate, control, and maintain average interior noise levels not greater than 45 CNEL. Contemporary exterior building construction is expected to achieve at least 15 decibels of exterior- to-interior noise attenuation with windows opened, according to the U.S. EPA (see reference). Therefore, exterior noise levels exceeding 60 CNEL are an indication that interior conditions may fail to meet the 45 CNEL requirement for occupied space, and an analysis of interior noise levels must be performed. Analysis for the interior noise levels requires consideration of: • Number of unique assemblies in the wall (doors, window/wall mount air conditioners, sliding glass doors, and windows) • Size, number of units, and sound transmission data for each assembly type • Length of sound impacted wall(s) • Depth of sound impacted room • Height of exterior wall of sound impacted room • Exterior noise level at wall assembly or assemblies of sound impacted room The Composite Sound Transmission data is developed for the exterior wall(s) and the calculated noise exposure is converted to octave band sound pressure levels (SPL) for a typical traffic-type noise. The reduction in room noise due to absorption is calculated and subtracted from the interior octave noise levels, and the octave band noise levels are logarithmically summed to yield the Eilar Associates, Inc. Job #B71107N1 December 28, 2017 Page 8 overall interior room noise level. When interior noise levels exceed 45 CNEL, the noise reduction achieved by each element is reviewed to determine which changes will achieve the most cost- effective compliance. Windows are usually the first to be reviewed, followed by exterior doors, and then exterior walls. 4.1.6 Formulas and Calculations The following formulas and calculations have been used in the preparation of this report. Sound Power to Sound Pressure To convert sound power levels to sound pressure levels, the following formula is used: SPL = SWL-20 log(D)-0.5 where: SPL= Calculated sound pressure level at distance, and D = Distance from source to location of calculated sound pressure level. Attenuation Due To Distance Attenuation due to distance is calculated by the equation: D SPL1 = SPL2 -20 log(-2 ) D, where SPL1 = Calculated sound pressure level at distance, SPL2 = Known sound pressure level at known distance, D1 = Distance from source to known sound pressure level, and D2 = Distance from source to location of calculated sound pressure level. This is identical to the more commonly used reference of 6 dB reduction for every doubling of distance. This equation does not take into account reduction in noise due to atmospheric absorption. Decibel Addition To determine the combined logarithmic noise level of two known noise source levels, the values are converted to the base values, added together, and then converted back to the final logarithmic value, using the following formula: Le = 10 log(l 0 1,1110 + 101,2110 + 1 0 LN no ) where Le = the combined noise level (dB), and LN = the individual noise sources (dB). Hourly LEo Summation To determine the hourly average noise levels (LEO) when the noise is created for less than the full hour, convert the logarithm values to the base energy value, multiply by the percentage of the hour that the noise occurs, and then convert the sum back to a logarithmic value. This is done with the following formula : Eilar Associates, Inc. Job #871107N1 December 28, 2017 Page 9 where PH = the percent or fraction of the hour noise is created, and Lp = the partial hour noise level (dB). 4.2 Measurement Equipment Some or all of the following equipment was used at the site to measure existing noise levels: • Larson Davis Sound Expert LxT Type 1 Sound Level Meter, Serial # 4084 • Larson Davis Model CA250 Calibrator, Serial# 1081 The sound level meter was field-calibrated immediately prior to the noise measurement and checked afterward, to ensure accuracy. All sound level measurements conducted and presented in this report, in accordance with the regulations, were made with a sound level meter that conforms to the American National Standards Institute specifications for sound level meters (ANSI S1 .4). All instruments are maintained with National Bureau of Standards traceable calibration, per the manufacturers' standards. 5.0 IMPACTS AND MITIGATION 5.1 Exterior 5.1.1 Noise Impacts to Outdoor Use Areas The City of Carlsbad requires residential projects to maintain noise levels of 60 CNEL or less at outdoor use areas. For the proposed residential units, a minimum of 60 square feet of private recreation space must be provided per unit. This requirement will be satisfied by the side yard of Unit 1, the second floor balconies of Units 2 and 3, and the roof decks of Units 4 and 5 (above the second floor). Traffic and railway noise impacts have been calculated at each of these private recreation areas using TNM and Cadna, respectively, to determine whether noise impacts exceed the 60 CNEL threshold. Calculations assume seated receivers on balconies and standing receivers at ground level. Results of this analysis are shown in Table 6 below. Additional information is provided in Appendices C and D, and a graphical representation of receiver locations is provided as Figure 8. Eilar Associates, Inc. Job #B71107N1 December 28, 2017 Page 10 ' Table 6. Future Combined Noise Levels at Outdoor Use Areas Approx.

For this reason, no mitigation is required for the attenuation of exterior noise impacts to the project site. 5 .1.2 Noise Impacts at Building Facades Noise impacts at building facades were calculated for use in interior noise calculations for on-site units. Future combined transportation noise impacts were calculated and found to range from 56 CNEL at the north facade of Unit 5 to 67 CNEL at the south facades of Units 1 and 5.

By FTA standards (see Section 4.1 .4), the number of trains traveling by the project site daily would classify the vibration as an infrequent event, and thus, the maximum acceptable vibration level is 80 VdB, as the number of trains traveling by the project site daily will not exceed 70 trips. Figure 10-1 from the referenced FTA publication, provided in Appendix E, shows Generalized Ground Surface Vibration Curves, which gives the RMS Velocity Level in VdB based on the distance from the track centerline and type of passing train, based on a reference speed of 50 mph. Vibration levels were calculated at the west side of Units 4 and 5, as these units are located nearest to the train tracks at a distance of approximately 220 feet. As train speeds were observed to range from 40 mph to 50 mph during the site visit, no speed adjustment was deemed necessary for the determination of ground vibration. Ground-borne vibration impact levels at the worst-case location on the project site are therefore expected to be approximately 71 VdB. As this vibration impact level falls below the acceptable threshold of 80 VdB, no mitigation is deemed necessary for the attenuation of ground-borne vibration impacts to the site. Eilar Associates, Inc. Job #B71107N1 December 28, 2017 Page 12 5.2 Interior The State of California and the City of Carlsbad require buildings to be designed in order to attenuate, control, and maintain interior noise levels not greater than 45 CNEL in habitable space, as formulated in the City of Carlsbad Noise Guidelines Manual and the California Building Code, Section 1207.4. Contemporary exterior building construction is expected to achieve at least 15 decibels of exterior-to-interior noise attenuation with windows opened. As a result, exterior noise levels of more than 60 CNEL often result in interior conditions that fail to meet the 45 CNEL requirements for habitable space. Exterior noise levels at many of the calculated receiver points on the proposed building facades exceed 60 CNEL, as shown in Table 8. Due to the elevated exterior noise levels at these building facades, an exterior-to-interior noise analysis was conducted for two worst-case units using typical building construction assumptions. Table 8 shows the results of the exterior-to-interior noise analysis for the two worst-case units (those with the highest anticipated noise exposure), with acoustical recommendations made therein. For more information, please refer to Appendix F: Exterior-to-Interior Noise Analysis. Table 8.

As the units evaluated above represent units with the highest noise exposure, all other units are expected to comply with interior noise level requirements with the same configuration recommended above. Calculations show that units will not comply with the City of Carlsbad and State of California interior ·noise regulations with windows and doors open; hence, mechanical ventilation will be required. The mechanical ventilation system shall meet the criteria of the California Mechanical Code, including the capability to provide appropriate ventilation rates. The ventilation system shall not compromise the sound insulation capability of the exterior wall or be dependent on ventilation through windows. Eilar Associates, Inc. Job #871107N1 December 28, 2017 Page 13 • • Exterior door installation should include all-around weather-tight door stop seals and an improved 'threshold closure system. The additional hardware will improve the doors' overall sound reduction properties. The transmission loss (TL) of an exterior door without weather-tight seals is largely a factor of sound leakage, particularly at the bottom of the door if excessive clearance is allowed for air transfer. By equipping exterior doors with all-around weather-tight seals and an airtight threshold closure at the bottom, a loss of up to 10 STC points can be prevented. Manufacturers of these products include such companies as Pemko and Reese, Additionally, it is imperative to seal and caulk between the rough opening and the finished door frame for all doors by applying an acoustically resilient, non-skinning butyl caulking compound. The same recommendation applies to any other penetrations, cracks, or gaps through the assembly. Sealant application should be as generous as needed to ensure effective sound barrier isolation, The OSI Green Series Draft and Acoustical Sound Sealant and the Pecora AC-20 FTR Sealant are products specifically designed for this purpose. Please see Appendix G: Recommended Products. The proposed residential units were analyzed for future exterior noise impacts from roadway traffic and railway operation. With typical exterior wall assemblies, glazing with a minimum STC rating of 28, and mechanical ventilation in units, all interior residential space is expected to comply with City of Carlsbad and California Building Code noise requirements. 5.3 Project-Related Noise Impacts on Surrounding Property Lines 5,3,1 HVAC Noise Anticipated HVAC noise levels have been estimated using distance attenuation calculations at the nearest surrounding noise-sensitive receiver, located to the north of the project site. The property lines of the project site and the residential receiver to the north are located approximately 40 feet apart. Considering the typical air conditioning unit detailed in Section 3.2.2, noise impacts of a single air conditioning unit at 40 feet would be expected to be approximately 40 dBA. As this noise impact falls below the most stringent property line noise limit of 45 dBA at nearby residential receivers, and as actual equipment is expected to be further setback from property lines and spread out on the project site, noise impacts at off-site receivers are expected to be in compliance with City of Carlsbad noise limits. No mitigation is deemed necessary for the attenuation of air conditioning equipment noise impacts. 5.3.2 Temporary Construction Noise According to the City of Carlsbad Municipal Code, Section 8.48.010, construction activity is prohibited between the hours of prohibited between the hours of 6 p.m. and 7 a,m., Monday through Friday, and between 6 p,m, and 8 a.m. on Saturday. During permissible hours of operation, the City does not have a noise limit with which construction noise must comply. As detailed construction information was not available at the time this analysis was prepared, estimated construction noise impacts have been calculated assuming -the typical pieces of equipment shown in Table 5 would be operating on site during the demolition and site preparation/grading process, Noise levels were calculated using the methodology and formulas detailed in Section 4.1.6 at the nearest residential receivers to the north/west of the project site. Assuming construction equipment would operate around the center of the property, the center of construction activity will be located at approximately 100 feet from the nearest residential property line on average. Based on the typical noise levels and duty cycles of construction equipment, when construction is operating in this worst-case location, average noise levels over the course of a typical eight-hour work day at the nearest residential property line will be approximately 70 dBA While this noise impact is slightly elevated above what the typical ambient noise levels would Eilar Associates, Inc. Job #B71107N1 December 28, 2017 Page 14 ' .. ordinarily be, this noise level remains in compliance with typically accepted construction noise limits employed by other municipalities, including the City of San Diego and the County of San Diego. Any other surrounding noise-sensitive receivers are located at a greater distance from proposed construction activity, and therefore will be exposed to lesser noise impacts due to additional distance attenuation and shielding provided by intervening structures. Despite the fact that there are no applicable noise limits, the following "good practice" measures should still be practiced as a courtesy to residential neighbors. 1. Staging areas should be placed as far as possible from residential receivers. 2. Place stationary equipment in locations that will have a lesser noise impact on nearby sensitive receivers. 3. Turn off equipment when not in use. 4. Limit the use of enunciators or public address systems, except for emergency notifications. 5. Equipment used in construction should be maintained in proper operating condition, and all loads should be properly secured, to prevent rattling and banging. 6. Schedule work to avoid simultaneous construction activities that both generate high noise levels. 7. Use equipment with effective mufflers. 8. Minimize the use of backup alarms. With operating hours limited to those permitted by the City of Carlsbad and adherence to the general good practice construction noise control techniques, temporary construction noise impacts will be limited at surrounding properties. 5.4 CEQA Significance Determination Noise impacts to and from the project site are summarized below and classified per the noise portion of the California Environmental Quality Act (CEQA) Environmental Checklist form. This list summarizes conclusions made within the report and classifies the level of significance as: Potentially Significant Impact, Less than Significant with Mitigation Incorporated, Less than Significant Impact, or No Impact. Italics are used to denote language from the CEQA Environmental Checklist form. XII. NOISE-Would the project result in: a) Exposure of persons to or generation of noise levels in excess of standards established in the local general plan or noise ordinance, or applicable standards of other agencies? Less Than Significant Impact. As documented herein, noise impacts to the proposed project site are anticipated to be less than the City of Carlsbad exterior noise standard at private recreation areas that satisfy the minimum 60-square foot requirement per unit. For this reason, exterior noise impacts are considered to be less than significant as currently designed. Eilar Associates, Inc. Job #B71107N1 December 28, 2017 Page 15 ... The interior noise analysis triggered by the exterior noise impacts at the site demonstrates that, with a typical exterior wall assembly, with glazing with a minimum rating •of STC 28, and with appropriate mechanical ventilation incorporated into the project design at all units, the noise limits of the City of Carlsbad and the State of California will be met at the project site. Operational noise impacts evaluated in Section 5.3 demonstrate that noise impacts generated at the project site by air conditioning equipment are not expected to exceed the applicable daytime or nighttime property line noise limits of the City of Carlsbad at surrounding receivers. For these reasons, this impact can be classified as less than significant. b) Exposure of persons to or generation of excessive groundbome vibration or groundbome noise levels? Less Than Significant Impact. The only anticipated source of ground-borne vibration levels at the project site is the nearby railway line. Per the assessment detailed in Section 5.1.3, vibration impact levels at the project site are expected to be approximately 71 VdB at the worst-case location on the project site. As this vibration impact level falls below the acceptable threshold of 80 VdB, this level of vibration does not require mitigation and is considered to be less than significant. c) A substantial permanent increase in ambient noise levels in the project vicinity above levels existing without the project? Less Than Significant Impact. The primary source of operational noise levels generated at the project site is future air conditioning units. Per the brief assessment in Section 5.3.1, noise impacts are expected to be less than the applicable noise limit of the City of Carlsbad. Additionally, considering the transportation noise impacts to the project site, it can be inferred that ambient noise levels are significantly elevated over any potential air conditioning equipment noise levels at off-site receivers. For this reason, this noise impact is considered to be less than significant. d) A substantial temporary or periodic increase in ambient noise levels in the project vicinity above levels existing without the project? Less Than Significant Impact. As shown in Section 5.3.2 of this report, noise from temporary construction is expected be less than significant considering the anticipated construction schedule and assuming that equipment is maintained in proper operating condition and using appropriate mufflers. It is unlikely that noise from temporary construction activity will cause a significant increase in ambient noise levels, due to the proximity of surrounding properties to the rail line and Tamarack Avenue. Additionally, no construction activity will take place during the more sensitive nighttime hours when ambient noise levels tend to be lower, as per City of Carlsbad requirements. Therefore, this impact is deemed to be less than significant. e) For a project located within 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? No Impact. The project site is not located within an airport land use plan nor is it located within two miles of a public airport or public use airport. Therefore, the proposed project would not expose people working in the project area to excessive noise levels from such uses. f) For a project within the vicinity of a private airstrip, would the project expose people residing or working in the project area to excessive noise levels? Eilar Associates, Inc. Job #B71107N1 December 28, 2017 Page 16 No Impact. The project site is not located within the vicinity of a private airstrip. Therefore, the proposed project would not expose people working in the project area to excessive noise levels from such uses. 6.0 CONCLUSION As per City of Carlsbad requirements, noise levels at outdoor use areas of the residential uses should be 60 CNEL or less. For the proposed residential units, a minimum of 60 square feet of private recreation space must be provided per unit. Future combined noise impacts were calculated at private outdoor use areas to determine compliance with this requirement. It was determined that, with the currently proposed configuration of the project site, each unit will include the minimum 60 square feet of private recreation space that is protected from noise impacts exceeding 60 CNEL. For this reason no mitigation is required for the attenuation of exterior noise impacts to the project site. A brief evaluation of ground-borne vibration impacts to the project site from the nearby rail line has also been conducted. It has been determined that the project will be exposed to vibration impacts that fall below the applicable thresholds established within the FTA Transit Noise and Vibration Assessment document. No mitigation is deemed necessary for the attenuation of vibration impacts at the project site. Due to high exterior noise levels at building facades, an exterior-to-interior analysis was performed to determine building features necessary for interior noise levels in residential habitable units not to exceed 45 CNEL, as required by the State of California and the City of Carlsbad. Calculations show that with typical exterior wall assemblies, all windows and glass doors of residential units should have a minimum rating of STC 28, and mechanical ventilation should be provided in residential units. With these project design features in place, interior noise levels are expected to comply with the regulations of the City of Carlsbad and the State of California. Project-generated noise impacts from the site to off-site receivers have been addressed. HVAC noise is expected to be adequately controlled at off-site receivers based on distance attenuation anticipated for typical air conditioning units. The City of Carlsbad Municipal Code does not provide noise limits for temporary construction activity at surrounding noise-sensitive property lines; however, the hours during which construction activity can take place are limited by Section 8.48.010 of the code. According to this section of the code, construction activity may not take place between the hours of 6 p.m. and 7 a.m., Monday through Friday, and between 6 p.m. and 8 a.m. on Saturday. The contractor can limit noise impacts at surrounding noise-sensitive receivers by adhering to the permissible hours of operation and following general good practice measures, including reasonable maintenance of equipment, conservative planning of simultaneous equipment operation, and using equipment with effective mufflers. The proposed project is not expected to result in any significant noise impacts, by the standards of the California Environmental Quality Act (CEQA). Noise impacts to and from the project site are summarized in Section 5.4. Eilar Associates, Inc.

OBJECTIVES AND IMPLEMENTING POLICIES AND ACTION PROGRAMS GENERAL C. IMPLEMENTING POLICIES AND ACTION PROGRAMS C. l Control harmful or undesirable sounds through the planning and regulatory process with emphasis on noise/ land-use compatibility planning. C.2 Review all development propos- als, both public and private, for consistency with the policies of this element. C.4 Continue to enforce. building codes to ensure adequate sound insulation be- tween dwellings and to ensure adequate sound insulation of interior areas from loud external noise sources. The City shall continue to enforce project conditions of approval related to noise control. C.5 Attempt to control noise primarily at its source. Where this is not feasible, controls along the transmission path of the noise should be required. LAND USE 8. OBJECTIVES 8.1 To achieve noise compatibility between industrial/ commercial and surround• ing land uses and achieve an acceptable noise environment in industrial/commercial areas. 8.2 To achieve noise impact compati- bility between land uses through the land use planning/development review process. C. IMPLEMENTING POLICIES AND ACTION PROGRAMS C.1 Encourage the development of compatible land uses in areas which are sub- ject to excessive noise levels. C.2 Develop specific noise standards for use in reviewing noise sensitive devel- opment. C.3 Require the use of project design techniques, such as, increasing the distance between the noise source and the receiver; placing non-noise sensitive uses such as park- ing areas, maintenance facilities, and utility areas between the source and the receiver; using non-sensitive structures, such as a ga- rage, to shield noise sensitive areas; and, orienting buildings to shield outdoor spaces from a noise source to minimize noise impacts during any discretionary review of a residential or other noise sensitive project. C.5 Enforce the policy of the City that 60 dBA CNEL is the exterior noise level to which all residential units should be mitigated. Sixty-five (65) dBA CNEL is the maximum noise level to which residential units subject to noise from McClellan-Palomar Airport should be permitted. Additional disclosure actions (easements, deed restric- tions, recorded notice, etc.) may be required of developers/sellers of noise impacted residential units. For residential properties identified as requiring a noise study, a study shall be pre- pared by an acoustical professional. This study shall document the projected maximum exterior noise level and mitigate the projected exterior noise level to a maximum allowable noise level as identified in this policy. Interior noise levels should be mitigat- ed to 45 dBA CNEL when openings to the exterior of the residence are open or closed. If openings are required to be closed to meet Noise Element Pohc1es 4 CITY OF CARLSBAD the interior noise standard, then mechanical ventilation shall be provided. If the acoustical study shows that exte- rior noise levels cannot be mitigated to the level allowable as identified in this policy or less, the development should aQ1 be approved without one or more of the following findings: 1. Changes or alterations have been required in, or incorporated into, the project which avoid or substantially lessen the sig- nificant environmental effect (noise). 2. Changes or alterations to avoid or substantially lessen the significant environ- mental effect (noise) are within the responsi- bility and jurisdiction of another public agency and not the City of Carlsbad. Such changes have been adopted by such other agency or can and should be adopted by such other agency. 3. Specific economic, social, or other considerations make infeasible the mitigation measures or project alternatives to avoid or substantially lessen the significant environ- mental effect (noise). If a project is approved with exterior noise levels exceeding the level allowable pursuant to this policy, all purchasers of the impacted property shall be notified in writing prior to purchase, and by deed disclosure in writing, that the property they are purchasing is, or will be, noise impacted and does aQ1 meet Carlsbad noise standards for residential property. Notwithstanding project approval, no residential interior CNEL should exceed 45 dBA. C.6 Require that a 'Noise" Study be submitted with all discretionary applications for residential projects of five or more single family dwelling units or any multiple family dwelling units located within or 500-feet beyond the 60 dBA CNEL Noise Contour Unes Noise Guidelines Manual as shown on the Map 2: Future Noise Exposure Contour Map. C. 7 Enforce the policy of the City that site design techniques such as increasing the distance between the noise source and the receiver; placing non-noise sensitive uses such as parking areas, maintenance facilities and utility areas between the source and the receiver; using non-noise sensitive structures, such as a garage, to shield noise-sensitive areas; and orienting buildings to shield outdoor spaces from a noise source, be the first tool used to mitigate noise impacts on noise sensitive land uses rather than the construction of walls or berms. C.8 Recognize that mitigation of existing or future noise impacts from Cir- culation Element roadways, AT&SF railroad or McClellan-Palomar Airport for existing or future development within the City, shall not be funded by the City. However, the City shall assist applicants with the processing of neces- sary permits for mitigating noise on private property, which permits may include right-of. way permits, encroachment permits, retaining wall permits and zoning variances. The City shall a/so assist property owners in the establishment of assessment districts, to fund noise mitigation improvements, in accordance with established City policies and procedures. CIRCULATION C. IMPLEMENTING POLICIES AND ACTION PROGRAMS C.2 Consider noise impacts in the design of road systems and give special con- sideration to those road corridors in scenic or noise sensitive areas. C.4 Apply the residential noise poli• cies of this element in the review of proposals for the construction or improvement of any roadway, railroad, transit system or other noise producing facility. Noise Element Pol1c1es 5 Table 5-3 provides standards for noise from non-transportation noise sources such as, but not limited to, industrial facilities, automotive servicing, car washes, equipment yards, nightclubs, hotels, and shopping centers. These standards apply to the noise sources themselves, as measured at the edge of the property line; noise caused by motor vehicles traveling to and from the site is exempt from this standard.

Where the location of outdoor activity areas is unknown, the exterior noise level standard shall be applied to the property line of the receiving use. 3 Where it is not possible to reduce noise in outdoor activity areas to the allowable maximum, levels up to 5 dB higher may be allowed provided that available exterior noise level reduction measures have been implemented and interior noise levels are in compliance with this table. 4 An exterior noise exposure level of 65 dBA CNEL is allowable for residential uses in a mixed-use project and for residential uses within the McClellan-Palomar Airport Area of Influence, pursuant to the noise compatibility policies contained in the ALUCP.

An owner/occupant or resident/tenant of residential property may engage in a home improvement or home construction project between the hours of 8:00 a.m. and 6:00 p.m. on Sundays and holidays, subject to modification by subsection B of this section, provided such project is for the benefit of said residential property and is personally carried out by said owner/occupant or resident/tenant. B. The building official, city engineer, or other official designated by the city manager may modify the hours of construction specified in Section 8.48.010. In making a determination to lengthen or shorten the hours of construction, the city official shall consider the following: I. Whether the project is an emergency repair required to protect the health and safety of any member of the community; 2. Whether the construction would be less objectionable at night than during daylight hours; 3. The character and nature of the neighborhood in the vicinity of the work site; 4. The potential for great economic hardship; 5. If the work is in the interest of the general public; 6. Whether there is a previously unforeseen effect on the health, safety or welfare of the public; and 7. Any history of complaints regarding compliance with the limitation on hours of construction. (Ord. CS- 211 § 2, 2013; Ord. 3109 § I, 1978) 8.48.030 Signage. Signs shall be posted at jobsite entrance(s) indicating hours of work as prescribed by this title or as modified by the designated city official. Letters shall be a minimum of four inches high with a minimum stroke width of one-half inch. (Ord.

The top curve applies to trains that are powered by diesel or electric locomotives. It includes intercity passenger trains and commuter rail trains. The curve for rapid transit rail cars covers both heavy and light-rail vehicles on at-grade and subway track. It is somewhat surprising that subway and at-grade track can be represented by the same curve since ground-borne vibration created by a train operating in a subway has very different characteristics than vibration from at- grade track. However, in spite of these differences, the overall vibration velocity levels are comparable. Subways tend to have more vibration problems than at-grade track. This is probably due to two factors: (I) subways are usually located in more densely developed areas, and (2) the airborne noise is usually a more serious problem for at-grade systems than the ground-borne vibration. Another difference between subway and at-grade track is that the ground-borne vibration from subways tends to be higher frequency than the vibration from at-grade track, which makes the ground-borne noise more noticeable. 100 ~---------------------~ --- 20 - Locomotive Powered Passenger or Freight (50 mph) Rapid Trci"11Sit·or Light Rail Vehicles (50 mph) ' 30 40 50 60 80 100 150 200 Distance from track centerline, ft (Use diagonal distance for underground systems) Figure 10-1. Generalized Ground Surface Vibration Curves 300 Groundborne Vibration Impact Level= 71 VdB The curves in Figure I 0-1 were developed from many measurements of ground-borne vibration. Experience with ground-borne vibration data is that, for any specific type of transit mode, a significant variation in vibration levels under apparently similar conditions is not uncommon.
