Job #S190102 January 10, 2019 Page 1 1.0 EXECUTIVE SUMMARY The proposed project, Madison Street & Oak Avenue, consists of the construction of a new residential complex consisting of five attached multi-family dwelling units. The project site is located at the east corner of Madison Street and Oak Avenue in the City of Carlsbad, California. The current and future noise environment primarily consists of traffic noise from Oak Avenue, Madison Street, Carlsbad Village Drive, and Interstate 5, as well as 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 are required to be 60 CNEL or less. Worst-case combined noise impacts were calculated at common and private outdoor use areas to determine compliance with this requirement. It was determined that, as designed, all common and private outdoor use areas will have noise impacts of 60 CNEL or less, in compliance with City of Carlsbad noise standards. No project design features are therefore deemed necessary for the attenuation of exterior noise impacts. The City of Carlsbad and the State of California require interior noise levels not exceeding 45 CNEL in residential habitable space. As building facade noise impacts are not expected to exceed 60 CNEL in the worst-case noise environment, interior noise levels are expected to comply with the 45 CNEL requirement with typical building construction, and no detailed interior noise analysis would be required for this development prior to issuance of building permits. 2.0 INTRODUCTION This acoustical analysis report is submitted to satisfy the acoustical requirements of the City of Carlsbad for tentative tract map, planned development permit, and site development plan 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. 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 LEQ, 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. _______________________________________________________________________________________ Eilar Associates, Inc. Job #S190102 January 10, 2019 Page 2 2.1 Project Description The proposed project, Madison Street & Oak Avenue, consists of the construction of a new residential complex consisting of five attached multi-family dwelling units. The dwelling units will each be three stories with balconies and a roof deck, and each will have an attached two-car garage. The amount of habitable space provided for each unit will range from 1,342 to 1,766 square feet. For additional information, please refer to project plans provided in Appendix A. 2.2 Project Location The project site is located at the east corner of Madison Street and Oak Avenue in the City of Carlsbad, California. The Assessor’s Parcel Number (APN) for the properties are 204-031-01 and 204-031-02. 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. 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. Please refer to Appendix B for pertinent sections of the City of Carlsbad Noise Guidelines Manual. 3.0 ENVIRONMENTAL SETTING 3.1 Existing Noise Environment The primary noise sources in the vicinity of the project site are traffic noise from Oak Avenue, Madison Street, Carlsbad Village Drive, 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 1,050 feet from the western property line of the site. Based on the current schedules for Amtrak and Coaster, approximately 48 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 three 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 56 CNEL at the northwest corner of the project site, without considering any shielding provided by intervening structures. With shielding taken into _______________________________________________________________________________________ Eilar Associates, Inc. Job #S190102 January 10, 2019 Page 3 account, the noise impact at the northwest corner of the project site is expected to drop to approximately 55 CNEL. Railway noise contours considering intervening structures were calculated for the site, and it was determined that noise impacts would range from approximately 54 CNEL to 55 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. 3.1.2 Roadway Traffic Noise Current and future traffic volumes are given based on information from the San Diego Association of Governments (SANDAG) Transportation Data, Series 12 Transportation Forecast Information Center, and Caltrans Traffic Counts. Additional information has been obtained from the Caltrans Traffic Census (see reference). Oak Avenue is a two-lane, two-way Local Roadway generally running east-west to the north of the project site. A posted speed limit could not be found for Oak Avenue, but nearby roadways are known to have a posted speed limit of 25 mph, and for this reason, a speed limit of 25 mph was assumed for Oak Avenue. No current or future traffic volumes were available for Oak Avenue in the vicinity of the project site. However, based on neighboring and surrounding land use, roadway classification, professional experience and on-site observations, a conservative volume of 1,000 Average Daily Trips (ADT) was used for Oak Avenue in the current environment. Madison Street is a two-lane, two-way Local Roadway generally running north-south to the west of the project site. The posted speed limit is 25 mph. No current or future traffic volumes were available for Madison Street in the vicinity of the project site. However, based on neighboring and surrounding land use, roadway classification, professional experience and on-site observations, a conservative volume of 1,000 Average Daily Trips (ADT) was used for Madison Street in the current environment. Carlsbad Village Drive is a four-lane, two-way Collector generally running east-west to the north of the project site. The posted speed limit is 25 mph. According to SANDAG, the current (2013) traffic volume on Carlsbad Village Drive is 16,600 ADT from State Street to Roosevelt Street, 19,100 ADT from Roosevelt Street to Madison Street, 21,200 from Madison Street to Jefferson Street, 23,600 ADT from Jefferson Street to Harding Street, and 32,100 ADT from Harding Street to Interstate 5. Interstate 5 (I-5) is an eight-lane, two-way Freeway generally running north-south to the east of the project site. The posted speed limit is 65 mph. According to Caltrans, the current (2017) traffic volume on I-5 is 208,000 ADT. 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 Oak Avenue, Madison Street, or Carlsbad Village Drive; 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 Oak Avenue and Madison Street, and a truck percentage mix of 2.0% medium and 1.0% heavy trucks was used for Carlsbad Village Drive. _______________________________________________________________________________________ Eilar Associates, Inc. Job #S190102 January 10, 2019 Page 4 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: Cadna Analysis Data and Results. Table 1.

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 54 and 56 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 afternoon of Monday, January 7, 2019, using the methodology described in Section 4.1. Due to numerous ambient noise sources in the vicinity of the site, the noise measurement was taken approximately 311 feet east of the Madison Street centerline, and 25 feet south of the Oak Avenue centerline. The microphone position was placed approximately five feet above the site grade. Traffic volumes for Oak Avenue were recorded for automobiles, medium-size trucks, and large trucks during the measurement period. After a 10-minute sound level measurement, there was no change in the LEQ and results were then recorded. The measured noise level and related weather conditions are found in Table 2. _______________________________________________________________________________________ Eilar Associates, Inc. Job #S190102 January 10, 2019 Page 5 Table 2. On-Site Noise Measurement Conditions and Results Date Monday, January 7, 2019 Time 12:04 p.m. – 12:14 p.m. Conditions Partly cloudy skies, winds at 9 mph, temperature in the low 60s with moderate humidity Measured Noise Level 61.7 dBA LEQ 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 (LEQ) 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 61.7 dBA LEQ at approximately 311 feet east of the Madison Street centerline, and 25 feet south of the Oak Avenue centerline, was compared to the calculated (modeled) noise level of 60.1 dBA LEQ 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: Cadna Analysis Data and Results for more information. Table 3. Calculated versus Measured Traffic Noise Data Location Calculated Measured Difference Correction 311’ E of the Madison St. C/L 25’ S of the Oak Ave C/L 61.7 dBA LEQ 60.1 dBA LEQ 1.6 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. The future (year 2035) traffic volumes for surrounding roadways were provided by SANDAG. The traffic volumes of Oak Avenue and Madison Street are conservatively estimated to increase to 2,000 ADT by the year 2035. By the year 2035, the traffic volume of Carlsbad Village Drive is estimated to increase to 16,900 ADT from State Street to Roosevelt Street, and 22,500 ADT from Roosevelt Street to Madison Street. By the year 2035, the traffic volume of Carlsbad Village Drive is estimated to decrease to 19,700 ADT from Madison Street to Jefferson Street, and 22,200 ADT _______________________________________________________________________________________ Eilar Associates, Inc. Job #S190102 January 10, 2019 Page 6 from Jefferson Street to Harding Street. The traffic volume of Carlsbad Village Drive is expected to remain the same from Harding Street to Interstate 5 in the year 2035. The traffic volume of Interstate 5 is expected to increase to 248,800 ADT by the year 2035. Additionally, Interstate 5 is expected to add four High-Occupancy Vehicle (HOV) lanes, with two lanes traveling in each direction, and therefore, the future traffic noise model reflects this addition. The roadway alignment and roadbed grade elevations are expected to remain the same for these sections of roadways. The same truck percentages from the existing traffic volumes were used for future traffic volume modeling. For further roadway details and projected future ADT traffic volumes, please refer to Appendix D: Cadna Analysis 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 55 and 58 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. 4.0 METHODOLOGY AND EQUIPMENT 4.1 Methodology 4.1.1 Field Measurement Typically, a “one-hour” equivalent sound level measurement (LEQ, 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 (LEQ) 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 (TNM) calculation protocol in Cadna Version 2018 (based on the methodology used in TNM Version 2.5, released in February 2004 by the U.S. Department of Transportation) was used for all traffic modeling in the preparation of this report. Using the TNM protocol, the CNEL is calculated as 0.092 times the ADT for surrounding roadways, based on the studies made by Wyle Laboratories (see reference). 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 _______________________________________________________________________________________ Eilar Associates, Inc. Job #S190102 January 10, 2019 Page 7 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 Cadna TNM, 6.9% of the ADT values for the current environment were used in calculations (for roadways that were not manually counted) to account for traffic between the hours of 12 p.m. and 1 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 (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. 4.2 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 # 2625 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 Exterior noise impacts to the project site are evaluated in this section and consider a combination of rail and traffic noise. As some current traffic volumes exceed those projected for the future, the higher of the two values has been used in these cases for a “worst-case” analysis of anticipated noise levels at the proposed project site. _______________________________________________________________________________________ Eilar Associates, Inc. Job #S190102 January 10, 2019 Page 8 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. The project has incorporated one common outdoor use area to the west of the property and private second floor balconies and roof decks for each unit. Traffic and railway noise impacts have been calculated at each of these outdoor use areas using Cadna to determine whether noise impacts exceed the 60 CNEL threshold. Calculations assume seated receivers on balconies and shielding provided by surrounding building structures. Results of this analysis are shown in Table 4 below. Additional information is provided in Appendices C and D, and a graphical representation of outdoor use receiver locations is provided as Figure 8. Table 4.

No project design features are required for the attenuation of exterior noise impacts at the project site. 5.1.2 Noise Impacts at Building Facades Worst-case combined noise impacts were also calculated at the second and third floor building facades of all units on site and were found to range from 48 CNEL at the second floor of the northwest facade of Unit 4 to 60 CNEL at the third floor of the north facade of Unit 4. A complete listing of calculated noise impacts is shown in Table 5, and a graphical representation of building facade receiver locations is shown in Figure 9. _______________________________________________________________________________________ Eilar Associates, Inc.

Current exterior building construction is generally 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, proposed project building structures exposed to exterior noise levels greater than 60 CNEL could be subject to interior noise levels exceeding the 45 CNEL noise limit for residential habitable space. As shown in Table 5, the maximum worst-case combined noise impact anticipated at project building facades is approximately 60 CNEL. As building facade noise impacts will not exceed 60 CNEL, all units on site are expected to comply with City of Carlsbad interior noise regulations of 45 CNEL or less with typical building construction, and therefore, no detailed interior noise analysis would be required for this project prior to the issuance of building permits. _______________________________________________________________________________________ Eilar Associates, Inc. Job #S190102 January 10, 2019 Page 10 6.0 CONCLUSION As per City of Carlsbad requirements, noise levels at outdoor use areas of the residential uses are required to be 60 CNEL or less. Worst-case combined noise impacts were calculated at common and private outdoor use areas to determine compliance with this requirement. It was determined that, as designed, all common and private outdoor use areas will have noise impacts of 60 CNEL or less, in compliance with City of Carlsbad noise standards. No project design features are therefore deemed necessary for the attenuation of exterior noise impacts. The City of Carlsbad and the State of California require interior noise levels not exceeding 45 CNEL in residential habitable space. As building facade noise impacts are not expected to exceed 60 CNEL in the worst-case noise environment, interior noise levels are expected to comply with the 45 CNEL requirement with typical building construction, and no detailed interior noise analysis would be required for this development prior to issuance of building permits. 7.0 CERTIFICATION All recommendations for noise control are based on the best information available at the time our consulting services are provided.

OBJECTIVES AND IMPLEMENTING POLICIES AND ACTION PROGRAMS GENERAL C. IMPLEMENTING POLICIES AND ACTION PROGRAMS C.1 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 B. OBJECTIVES B.1 To achieve noise compatibility between industrial I commercial and surround- ing land uses and achieve an acceptable noise environment in industrial/ commercial areas. B.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 subjectto 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 /eve/ and mitigate the projected exterior noise /eve/ 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 Policies 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 not 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 not 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 Lines 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. IMPLEMENT/NG 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.
