No ocher noise sources in the vicinity of the project site art: considt:rcd to bt: significant. 3.1.1 Roadway Noise Sources Current traffic volumes for all roadways arc given based on information from the San D iego Association of Governments (SANDAG) S<.:ries 14 Transportation Forecast Information Center (TF!C) (sec reference). Marron Road is a C\\·o-lane, C\vo-way Local Roadway running cast-\\'CSt along rhe north boundaC)' of the project site. The posted speed limit is 25 mph. According to S,\ND,\G, the current traftic \"!,lume of:\Iarron Road is 1 _\000 ,\verage Daily Trips (ADT) as of the year 2016. R-78 is a six-lane, C\Vo-way Freeway running case-west to the north of the project site. The posted speed limit is 65 mph. According co SJ\NDJ\G, SR-78 currently carries 64,600 J\DT traveLing eastbound and 64,700 J\ OT traveling westbound as of the yea r 2016. College Boulevard is a six-lane, two-way '.\fajor Arterial running generally north-south co the east of the project site. The posted speed limit is 35 mph. According co SANDAG, College Boulevard carries a traffic \'olume of approximately 39,000 ,-\DT as of the year 2016. o current or future truck percentages were available for any of the roadways in the ,~cinity of the project site other than for SR-78. However, based on neighboring and surrounding land use, roadway classification, professional experience, and on-site observations, a truck percenta!"(e mix of 1.0% medium and 1.0% heavy trucks ,ms used for Marron Road, and a mix of 3.0% medium trucks and 2.0% heavy trucks was used for College Boulevard. According to the 2018 Caltrans Truck Traffic on Fn:cways publication (sec reference), SR- 78 currently carries a truck pcrcenrage mix of 2.29% medium and 2.58% heavy. Current and future (Sec Section 3.2) traffic volumes and vehicle mixes for road,rny sections near the project site arc shown in Table I. Table 1.

The \\·cather conditions were as follows: cloudy skies, high humidity, and temperature in the mid 70s with winds at 9 mph. /\ noise measurement was made near the north property line of the project site, approximately 40 feet south of the Marron Road centerline. The primary source of noise during the measurement was traffic noise. The microphone was placed at approximately five feet ab.ovc the existing grade. Traffic volumes for :>.1arron Road were recorded for automobiles, medium-size trucks, and large trucks during the measurement period. After a 20-minute continuous sound level measurement, no changes in the Lu, were ohsen-ahlc and results were recorded. The measured noise level and related weather conditions are shown in Table 2, and the noise measurement location is shown on Pigure 5. Table 2. On-Site Noise Measurement Conditions and Results Date Monday, ,\ugust 24, 21121! Time 3:'I 8 p.m. -3:38 p.m. Conditions Cloudy skies, wind at 9 mph, temperature in the mid 70s with high humidity Measured Noise Level 57.4 dBA L, q 3.1.3 Calculated Noise Level Noise levels were calculated for the site using the methodology d,scribed in Section 4.1.2. The calculated noise levels 0-i-Q) were compared with the measured traffic noise lc\-cl to determine if adjusm1ents or corrections (calibration) should be applied to the traffic noise prediction model. ,\djuscments arc intended to account for sitc-spccitic differences, such as reflection and absorption, which may be greater or lesser than accounted for in the model. T he measured noise level of 57.4 dH,\ L,,,, at approximately 40 feet south of the :\larron Road centerline was compared co the calculated (modeled) noise level of 57.6 dHA L1 'l for the same anticipated traffic flow. /\ccording to the Federal Highway ,\dministration's Highway T raftic Noise: Analysis and ,\batemcnt Guide (sec reference), a traffic noise model is considered ,·alidatcd if the measured and calculated noise impacts differ by three decibels or less. No adjustment was deemed necessary to model peak hour noise levels fo r the proposed building as the difference between the measured and calculated levels was found to be less than three decibels. This information is presented in Table 3. Please refer to Appendix C for more information. Table 3.

The future traffic volumes for roadways were obtained from the SANDAG Series 14 TFlC. In the ,·icinicy of the project site, the traffic rnlume of:\larron Road is expected to increase to 14,70(J ADT by the year 2035. The traffic volume of SR-78 is expected to increase to 73, I 00 ADT traveling eastbound and k f' ( I ,1,\r 1' H -, 11 ,..,11' ~ \ Eilar Associates, Inc. 75,100 J\DT hy the year 2035. The traffic volume of College Boulevard is expected to increase to 40,200 J\OT by th e year 2035. The same truck percentages from the current rraffic volumes were used for future traffic ,·olurne modeling. For further roadway details and projected future ADT traffic volumes, please refer co Appendix C. 4.0 Methodology and Equipment 4.1 Methodology 4.1.1 field Measurement Typicall y, a "one-hour" c4uiYalent sound lcYcl measurement (LHb ,\-\'\'cighced) is recorded for at least one noise-sensitive location on the site. During the on-site noise measurement, start and end times arc recorded and vehicle counts arc made for cars, medium trucks (douhlc-tircs/cwo axles), and heavy trucks (three or more axles) for the corresponding road scgrnent(s). Supplemental sound measurements of one hour or less in duration arc often made to further describe the noise cnYironment of the sir.e. For measurements of less than one hour in duration, the measurement time is long enough for a rcprcscncativc traffic volume to occur and the noise level (l..1 ,i) to stabilize. The vehicle counts arc then convened to one- hour e4uivalenc ,·olumes by applying an appropriate factor. Other field data gathered include measuring or estimating distances, angles-of-view, slopes, elevations, roadwar grades, and vehicle speeds. This in fo rmation is subsequently verified using available maps and records. 4.1.2 Roa<lway Noise Calculation The Traffic Noise Model (fNM) calculation protocol in CadnaA Version 2020 (based on the methodology used in TNl'vl Version 2.5, released in February 2004 by the U.S. Department of Transportation) \\·as used to determine the peak hour noise level (dBA Lui) during hours of operation (dBA L1-.,iJ. In order to determine this value, the Average Daily Trips (ADT) value is divided into percentages for each hour of the day to establish maximum noise impacts that the project site may experience during a 24-hour period. These percentages were established in a study performed by Katz-Okitsu and Associates, Traffic Engineers (sec reference). According to chis study, the peak traffic volume expected during proposed operational hours is approximately 8.6% of the ADT value (bct\,·ecn the hours of 4 p.rn. and 5 p.rn.). For this analys is, the peak volume percentage of traffic volurncs was used as a worst case. In order to determine the estimated traffic volumes of roadways during the traffic noise measurement made on sire for model calibration, the approximate percentage of the ,\vcragc Dail y Trips (,\OT) value for the ti me period in which the measurement is made is incorporated into the traffic model. These percentages were cst~blishcd in a study performed by Katz-Okitsu and ,\ssociatcs, Traffic Engineers (sec reference). For purposes of calihrati ng the Cadna/\ TNi\-f, 8.()0 " of the ,\OT values for the current environment were used in calculations (for roadways rhar were not manually cmmtcd) en account for traffic between the how·s of] p.m. and 4 p.m. in the vicinity of the project sire. 4.1.3 Exterior-to-Interior Noise i\nalysis The City of Carlsbad ret1ui1·cs non-residential buildings containing preschool uses to be designed in order co attenuate, control, and maintain average interior noise levels not greater than a one-hour average of 45 dBA. Contemporary exterior building construction is expected co achieve at least 15 decibels of exterior-to-interior noise attenuation with windows opened, according to the .S. EPJ\ (sec reference). i\s a result, exterior noise 'l \ I K ll< P,1 (\ l \ I I l • 1, 1 -..i, I :-1 ! • \ I l •11 •1 p,. I Eilar Associates, Inc. levels oi more than 60 dBt\ may result in interior conditions that fail to meet the 45 dBi\ rcc1uircmcnts for occupied space. Analysis for the interior noise levels requires consideration of: • Number of unique assemblies in the wall (doors, "·indow/,,·all 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 Jue to absoq)[ion is calculated and subtracted from the interior octave noise levels, and the octave band noise levels are logarithmically summed to yield the overall interior room noise level. When interior noise levels exceed 45 dBr\, the noise reduction achieved by each clement is reviewed to determine which changes will achieve the most cost-effective compliance. \'v'indows arc usually the first to be reviewed, followed bl' exterior doors, and then exterior walls. Modeling of wall assemblies is accomplished using INSUI. Version 9.0, which is a model-based computer program, developed by Marshall Day Acoustics for predicting the sound insubtion of walls, floors, ceilings, and windows. Ir is acoustically based on theoretical models that rec1uirc only minimal material information that can make reasonable estimates of the sound transmission loss (Tl.) and STC for use in sound insulation calculations; such as the desi1,'11 of common party walls and multiple family floor-ceiling assemblies, ere. TNSUL can he used to quickly evaluate new materials or systems or im-cstigate the effects of changes to existing designs. le mndcls individual materials using the simple mass law and coincidence frequency approach and can model more complex assembly partitions. le has evolved over several versions into an easy to use tool and has refined the theoretical models by continued comparison with laboracory tesrs co prmide acceptable accuracy for a "~de range of constructions. INS CL model performance comparisons with laboracory test data show that the model generally predicts the performance of a given assembly within 3 STC points. 4.2 Measurement Equipment Some or all of the following eq,,ipment was used at the site to measure existing noise levels: • Larson Davis !',lode! LxT Type 1 Sound Level Meter, Serial # 4085 • Larson Davis ~lode! CA250 Type 1 Calibrator, Serial# 2l06 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 chat conforms to the American National Standards Institute specifications for sound level meters (ANSI S 1.4). All instruments are maintained with National Bureau of Standards traceable calibration, per the manufacturers' standards. I', Eilar Assodates, Inc. 5.0 Impacts and Mitigation 5.1 Exterior (Building Facades) Peak hour traffic noise impacts were calculated at the building facades for use in interior noise calculations using traffic information sh,rn·n in Section 3.0. Future peak hour noise impacts at these locations arc shown in Table 4. As some roadways ha\'e a higher elevation than the building, two n:ceivers (RB and R9) were placed on the roof to determine apprnximat<: traffic noise impacts at the roof. More information is pro,·ided in Appendix C, and receiver locations arc shown in Figure 5. Table 4.

The roof assembly was included in this ernluation as the roof will be exposed to some noise from traftic due to the clerntion of SR-78 above the proposed building. The exterior wall is expected to he constructed as stucco over plywood sheathing on the exterior with two-inch by six-inch wnod framing, insulation in the cavity, and 5/8-inch gypsum board on the interior. This wall assembly was calculated using INSUL and is expected to have a rating of STC 41. The worst-case 0owest sound rating) roof/ceiling assembly is expected to consist of a roof membrane over plywood sheathing, with a suspended acoustical ceiling and batt insulation in the cavity. According to INSL'L, the roof /ceiling STC rating is expected ro achieve a rating of STC 53. Please refer co Appendix D for more dernils. Proposed windows \\·ere e\'aluared as STC 25 glazing units and doors were enluated as STC 20 single pane glass doors for a conser\'ati,·e analysis of standard commercial glazing. Interior noise calculations were performed using the exterior wall, roof, and gla~ing information detailed above co determine whether interior noise levels of 45 dBA nr less can be achieved during the worst-case hour of I J 1•1 • I, 11• °' ~ I l • \ f 1 'I I •1 Eilar Associate..,, Inc. operation. Please refer to Table 5 for interior noise level results, and refer to Appendix E for additional in formation. Table 5.

As this represents the maximum noise impact in any one hour period during the day expected to be experienced at the building, all other hours are expected to ha,·e interior noise impacts that are less than those shown above. f .xn:rior door installation should include all-around weathcr-tight door stop seals and an improved threshold closure system. The additional hardware will improve the doors' overall sound reduction properties. The transmission loss (fL) of an exterior door without weather-eight scals is largcly a factor of sound leakage, particularly at the boccom of the door if excessivc clearance is allowcd for air transfer. Bv e9uipping extcrior doors with all-around wcather-tight scals and an airtight threshold closure at the bottom, a loss of up to IO STC points can bc prevented. Additionally, it is imperative to seal and caulk between the rough opening and the finished door frame for a.II doors hy applying an acousticall y resilient, non-skinning, butyl caulking compound. The same recommendation applies to any other penetrations, crac ks, or gaps through the asscmhly. Sealant application should he as generous as needed to ensure effective sound barrier isob tion.

The proposed project was analyzed for peak hour traffic noise impacts. With the proposed exterior wall and roof assemblies and standard commercial glazing in place, all occupied rooms are expected to comply with Ciry of Carlsbad noise re9uirements. 6.0 Conclusion Calculations show that, with the proposed exterior wall and roof assemblies and standard commercial glazi ng, interior noise levels of 45 dBi\ or less can be achieved during the worst-case hour of operation (peak hour traffic). r\s designed, all occupied rooms a.re expected to comply with City of Carlsbad noise req,tiremcnts. \1 ,,u < i 1·1· ..., 11 •\I l • \ Eilar Associates, Inc. 7.0 Certification All recommendations for noise control arc based on the best information available at the time our consulting services arc provided.
