Included in this report is a discussion of the expected exterior community noise environment and the recommendations for control of noise in the exterior and interior living areas. A vicinity map showing the general location of the construction site is presented on Exhibit 1 -- Site Location Map. The proposed development is 18, single family detached buildings. 2.0 APPLICABLE NOISE CRITERIA ,The City of Huntington Beach requires all residential projects to conform to the requirements of Table 1. TABLE 1 APPLICABLE NOISE CRITERIA(1) Exterior ...... 65 CNEL Interior ...... 45 CNEL (1) Please see NOISE RATING METHODS (Appendix l) for a complete explanation of acoustical terminology. 1621 East Seventeenth Street, Suite K Santa Ana, California 92701 • Phone (714) 835-0249 FAX (714) 835-1957 i 90/477 3.0 EXISTING NOISE LEVELS 3.1 ROADWAYS A measurement was performed on the site. The record of this measurement is attached as Exhibit 2. Measurements are conducted using a Bruel and Kjaer (B & K) Model 2209 Type 1 Sound Level Meter, a B & K Model 2306 Strip Chart Recorder, and a B & K Model 4426 Statistical Noise Analyzer . The Average Noise Level reported from this measurement was 70 Leq. The measurement was taken at a point 65 feet from the centerline of Warner Avenue. A ten minute traffic count was taken during the measurement period. The results of, that count are given in Table 2. TABLE 2 TEN MINUTE TRAFFIC COUNTS AUTOS MEDIUM TRUCKS HEAVY TRUCKS TOTAL TEN MINUTES 202 2 0 204 HOURLY EQUIVALENT 1,212 12 0 1,224 PERCENTAGE 99.0 2.0 0 100.0 The primary function of the measurements is to calibrate the Noise Model (FHWA RD-77-108) used to compute the CNEL data. The model relies on the acoustical metric of the Average Noise Level (Leq). By taking the traffic count during the measurement, calculating the Leq value for that sample, and comparing it to the measured sample, it is possible to calibrate the CNEL model for any factors which are present, and riot adequately identified in the prediction equations. The computer print-out.is attached in Appendix 2. The calculated levels and the measured level are compared in Table 3 on the following page. 90/477 TABLE 3 COMPARISON OF CALCULATED AND MEASURED AVERAGE NOISE LEVELS Calculated 70 Measured 70 DIFFERENCE 0 The calculated and measured values correspond. Therefore, no corrections need be applied to the CNEL calculations. 3.2 RAILROAD There is no railroad near the site. 3.3 AIRCRAFT There is no airport near the site. 3.4 STATIONARY There are no stationary sources near the site. 4.0 DESIGN NOISE LEVELS 4.1 ROADWAY The expected future roadway noise impact was projected Ling the Federal Highway Admini- stration's Highway Noise Prediction Model (FHWA RD-77- 108) together with several roadway acid site parameters, which determine the projected impact of vehicular traffic noise, including the roadway crossection (e.g. number of lanes), t e roadway active width, the average daily traffic (ADT), the vehicle travel speed, the percentages of auto and truck traffic, the roadway grade, the angle-of-view, the site conditions ("hard " or "soft"), and the percent of total average daily traffic which flows each hour throughout a 24-hour period. The forecast traffic volume was obtained from the Warner Avenue widening EIR at 42,000 ADT. 90/477 The percentage of truck traffic was obtained from a 1987 Study of Thirty-one Arterial Intersections. by the County of Orange. The same source was used for the distribution by the time of day. The data is listed in Table 4. TABLE 4 TRAFFIC INPUT DATA -- WARNER % DAY % EVENING % NIGHT % VOLUME Autos 75.51 12.57 9.34 100.0 Medium Trucks 1.56 .09 .19 100.0 Heavy Trucks .64 .02 .08 100.0 Volume = 42,000 ADT The calculations are listed in Appendix 3. The calculations yield a. design noise level of 75 CNEL at 50 feet from the centerline of Warner. The noise contours are shown on Exhibit 3 for the vacant site. 4.2 RAILROAD Railroad noise is not expected to occur. Thus, railroad noise will not impact the site. 4.3 AIRCRAFT Aircraft noise is not expected in the future. Thus, aircraft noise will impact the site. 4.4 STATIONARY Stationary sources are not expected to impact the site. 5.0 MITIGATION MEASURES 5.1 EXTERIOR The mitigation of exterior noise will require a barrier along Warner since the levels will exceed 65 CNEL. The assumptions for the barrier calculations are listed in Table 5 on the following page. 90/4.77 TABLE 5 BARRIER ANALYSIS GENERAL ASSUMPTIONS FOR RECEIVER AND SOURCE GEOMETRY RECE IVERASSUMPTI0NS HORIZONTAL GEOMETRY VERTICAL G23METRY Distance behind top-of-roadways Height above pad for ground barrier: 5' to 10' level receivers: 5' Distance behind individual Height above pad for second patio and balcony barriers: level receivers: 14' 1' to 3' S 0 U R C E A S S U M P T I O N S For roadways with grades no Automobiles: 0' above center- greater than 2%, all vehicles line road grade were located at the single lane equivalent acoustic center of Medium Trucks: 2.3' above the full roadway. For roadways centerline road with over 2% grade, vehicle grade count was divided in half and located at the single lane Heavy Trucks: 8' above equivalent acoustic center for centerline road each side of the roadway. grade Single lane equivalent (SLE) location. The results of the barric,r calculations, contained in Appendix 4, show that an eight foot (8') sound wall will be needed to reduce noise levels to a maximum exterior level of 65 CNEL. Balconies are not required to be attenuated since these are not stacked units and private open space is available at the first floor level. The barrier location is depicted on Exhibit 4. HORIZONTAL GEOMETRY* VERTICAL GEOMETRY 90/477 The required noise control barriers may be constructed using one of the following materials: (1) Masonry block (2) Stucco on wood frame (3) 3/4" plywood (4) 1/4" glass or 1/2" Lr^,XAN (5) Any combination of these materials or any material rated 3.5 pounds per square foot surface weight or greater. Each completed noise control barrier must present a solid face from top-to-bottom. Cutouts and openings are not permitted except for drain holes. 5.2 INTERIOR The City's exposure criteria for new resi- dential construction requires that the interior noise e:vironment, attributable to outside sources, be limited to 45 CNEL. Analysis and recommendations for control of outdoor-to-indoor noise intrusion are presented in this section. The exterior-to-interior rio--.se reduction expected for the planned construction was' based on a detailed analysis of sample rooms and units planned for the development. Calculations of the expected typical noise reduction performance were performed for sample rooms. The analysis was based on the typical spectra expected for the primary sources of community no:)se impact, the typical octave-band transmission loss for each element in the planned building shell, the relative square footage of each element of the planned building shell, the expected typical interior surface treatment, and the acoustical absorption coefficient for each interior surface treatment. Corrections for the "A" Weighted room absorption factors are also included. Each component of the building shell (e.g. exterior wall, windows, doors, etc.) provides a different amount of transmission loss for each "A" Weighted octave-band of community noise. With the knowledge of the building shell components and their individual octave band transmission loss values for the noise sources, calculations of the composite building shell transmission loss can be made for each room. 8 90/477 I The Table 6 construction minimums will provide around 20 dBA interior noise _r. eduction. This would be adequate for the first floor since the sound wall reduces levels to 65 CNEL, and 20 dBA of reduction is all that is required to achieve 45 CNEL . At the second and third floors, the situation varies. The required redaction is noted on Exhibit 5 Calculations were carried out for sample rooms and are contained in Appendix 5. The variable was the glazing. The results are given in Table 8.

Since community noise is seldom constant, varying from moment to moment and throughout the day, the "A" weighted noise level needs to be further described to provide meaningful data. The Environmental Protection Agency, Federal Department of Transportation, foreign countries and private consultants are now using three time-exceeded percentile figures to describe noise, which are: (1)L90 is the noise level 90% of any sample time hours) and is used to describe ambient noise level. (2) L50 is the noise 50% of the time. (3)L10 10% fluctuating is the level which is exceeded period (such as 24 the background or which is exceeded it is the median level. noise level which is exceeded of the time and is a good descriptor of noise sources, such as vehicular traffic. It indicates the near-maximum grouped single events. Being annoyance to community noise, levels which occur from related to the subjective it is a good design tool 1 621 East Seaenm,eenth Street, Suite K • Santa Ana, Cat forr,,ia927010 Phone (7141835-0249 Page 2 of 3 in the planning of acoustical barriers. More recent noise assessment methods are based on the equivalent energy concept where Leq(x )represents the average energy content of a fluctuating noise source over a sample period. The subscript (x) represents the period in which the energy is computed and measured . Current practice references the quantity to either one (1 ) hour, eight (8) hours, or twenty- four (24) hours . Wher referenced to one (1) hour, Leq is also sometimes called HNL (Hourly Noise Level). Since Leq is the summation of the functional products of noise level and duration, many combinations of noise level, duration time and time history can make up the same Leq value. Thus, an Leq (24)equals 50 means only that the average noise level is 50 dB. During the 24-hour period there can be times when the noise level is higher than 50 dB, and times when it is lower. If the period of the measurement is only a single event, the energy content is not averaged . The energy expression for a single event is simply the sum of the functional product of the noise level and duration time of the event , This term is called Le or SENEL (Single Event Noise Exposure Level). The summation of Le values averaged over one hour is Leq(1), Leq(8 ), and Leq (24), etc. L•eq is further refined into Ldn (Level Day-Night) and CNEL (Community Noise Equivalent Level) , where noises that occur during certain hours of the day are weighted (or penalized) because they are considered subjectively more annoying during these time periods: (1)Ldn is the sound level in dBA which corresponds to the average energy content of the noise being measured over a 24-hour period including a 10 dBA weighting penalty for sound levels which occur during the nighttime hours of 10:00 P.M. to 7:00 A.M. This is a rating method recommended by the Environmental rage .s or .3 Protection Agency because it takes into account those subjectively more annoying noise events which occur during the sleeping hours. (2) CNEL is the sound level in dBA which corres- ponds to the average energy content of the noise being measured over a 24-hour period including a five (5) dBA penalty for noise which occurs during the evening hours of 7:00 P.M. to 10:00 P.M., and a ten (10) dBA weighting penalty for noise that occurs durina the night- time hours of 10;00 P.M. to 7:00 A.M. For typical high- way vehicular traffic situations, computer analysis has shown that CNEL and Ldn correlate within 0.5 dBA. The percentile figures L10,L50,and L 90 can be directly scaled from a graphical recording of the measured noise over a particular time period. They are also convenient to implement in automatic measurement equipment. Energy parameters Le' Leg' Ldn'and CNEL require expensive and complicated equip- ment. As a result, engineers have devised ways of estimating Leq (and hence, Ldn) using standard instrumentation and methods.
