The Carlsbad Joint First Responder project includes the construction of four major facilities: a Public Safety Facility, a Fire Administration Building, Residential Bum Prop Facility, and a Commercial Bum Prop Facility (Figure 2). The Public Safety Facility would contain a shooting range and classroom building, occupying 32,426 square feet. The Fire Administration Building would be centralized in a 9,746 square foot, two-story building. The Residential Burn Prop Facility would be a 2,246 square foot, two- story structure designed to simulate a single-family house. The Commercial Burn Prop Facility, the most centrally located structure on the project site, would be a 6,588 square foot, four-story building. The first floor is designed to resemble retail and office space and the second floor is designed to resemble office and apartment space. Outdoor features of the facility include rodeo/drill grounds in the northwest portion of the site, an outside classroom area, a cul-de-sac training area adjacent to the Residential Bum Prop Facility, an automobile extrication area, and parking. Fire training activities would occur between the hours of 7:00 a.m. and 10:00 p.m. allowing the responders to work in daylight and darkness, which is critical to their training and operations. Training activities would include standard interior fire fighting training, multiple company training, search and rescue training, car extrication training, trench rescue, and driver's training. Standard police outdoor training would also take place involving search and locate activities. The police would not be performing any outdoor training exercises that would utilize either blanks or Simunition. Police training activities would occur between the hours of 7:00 a.m. and 10:00 p.m. allowing the responders to work in daylight and darkness to provide real world scenarios, which is critical to their training and operations. The project site would be bounded by Orion Street and the semi-circular Orion Way, which is a one way street. The site is currently designated as a recreational park. Surrounding land use includes Carlsbad police buildings to the north and east, a fire department building to the south, and an industrial park to the west. Nearby noise sensitive areas include the La Posada de Guadalupe de Carlsbad Shelter to the northwest and the Carlsbad Oaks North Habitat Conservation Area to the southeast.

The human environment is characterized by a certain consistent noise level which varies by location and is termed ambient noise. Although exposure to high noise levels has been demonstrated to cause hearing loss, the principal human response to environmental noise is annoyance. The response of individuals to similar noise events is diverse and influenced by the type of noise, perceived importance of the noise and its appropriateness in the setting, time of day and type of activity during which the noise occurs, and sensitivity of the individual. Sound is a physical phenomenon consisting of minute vibrations that travel through a medium, such as air, and are sensed by the human ear. Sound is generally characterized by several variables, including frequency and intensity. Frequency describes the sound's pitch and is measured in cycles per second, or hertz (Hz), whereas intensity describes the sound's loudness and is measured in decibels (dB). Decibels are measured using a logarithmic scale. A sound level of 0 dB is approximately the threshold of human hearing. Normal speech has a sound level of approximately 60 dB. Sound levels above about 120 dB begin to be felt inside the human ear as discomfort and eventually as pain at still higher levels. The minimum change in the sound level of individual events that an average human ear can detect is about 3 dB. The average person perceives a change in sound level of about 10 dB as a doubling (or halving) of the sound's loudness; this relation holds true for sounds of any loudness. Sound levels of typical noise sources and environments are provided in Table I. Because of the logarithmic nature of the decibel unit, sound levels cannot be added or subtracted directly and are somewhat cumbersome to handle mathematically. A simple rule is useful, however, in dealing with sound levels. If a sound's intensity is doubled, the sound level increases by 3 dB, regardless of the initial sound level. Thus, for example, 60 dB+ 60 dB = 63 dB, and 80 dB + 80 dB = 83 dB. The normal human ear can detect sounds that range in frequency from about 20 Hz to 20,000 Hz. However, all sounds in this wide range of frequencies are not heard equally well by the human ear, which is most sensitive to frequencies in the range of 1,000 Hz to 4,000 Hz. This frequency dependence can be taken into account by applying a correction to each frequency range to approximate the human ear's sensitivity within each range. This is called A-weighting and is commonly used in measurements of community environmental noise. The A-weighted sound pressure level (abbreviated as dBA) is the sound level with the "A-weighting" frequency correction. In practice, the level of a noise source is conveniently measured using a sound level meter that includes a filter corresponding to the dB A curve. Because community noise fluctuates over time, a single measure called the Equivalent Sound Level (Leq) is often used to describe the time-varying character of community noise. The Leq is the energy-averaged A-weighted sound level during a measured time interval. It is equal to the level of continuous steady sound containing the same total acoustical energy over the averaging time period as the actual time- varying sound. Additionally, it is often desirable to know the acoustic range of the noise source being measured. This is accomplished through the Lmax and Lmin indicators, which represent the root-mean- square maximum and minimum noise levels obtained during the measurement interval. The Lmin value obtained for a particular monitoring location is often called the "acoustic floor" for that location. K:\NOISE\095413001\Report\First Resporxlers Faciity Noise Analysis Report 09·18·200'!.dx 2 I I I I I I I I I I I I I I I I I I I To describe the time-varying character of environmental noise, the statistical noise descriptors L I 0, L50, and L90 are commonly used. They are the noise levels equaled or exceeded during 10, 50, and 90 percent of a stated time, respectively. Sound levels associated with Ll 0 typically describe transient or short-term events, whereas levels associated with L90 describe the steady-state (or most prevalent) noise conditions. Another sound measure known as the Community Noise Equivalent Level (CNEL) is an adjusted average A-weighted sound level for a 24-hour day. It is calculated by adding a 5 dB adjustment to sound levels during evening hours (7:00p.m. to 10:00 p.m.) and a 10 dB adjustment to sound levels during nighttime hours (10:00 p.m. to 7:00 a.m.). These adjustments compensate for the increased sensitivity to noise during the typically quieter evening and nighttime hours. CNEL is used by the State of California and County to evaluate land-use compatibility with regard to noise. Some land uses are considered sensitive to noise. Noise sensitive areas are land uses associated with indoor and/or outdoor activities that may be subject to stress and/or significant interference from noise. Noise sensitive areas often include residential dwellings, mobile homes, hotels, motels, hospitals, nursing homes, educational facilities, and libraries. Industrial, commercial, and agricultural land uses are generally considered not sensitive to noise.

The primary noise source within the project vicinity is vehicular traffic on Orion Street. Orion Street has an existing a.m. peak-hour traffic volume of approximately 48 vehicles (LSA Associates, Inc. 2008). The posted speed limit on these roadways is 25 miles per hour (mph). The existing vehicular traffic on Orion Street generates a noise level of approximately 4 7 dB A at the La Posada de Guadalupe de Carlsbad Shelter. Noise from the fire station and other facilities at the surrounding Carlsbad government complex contribute to the noise environment. In addition, McClellan-Palomar Airport and the North County Waste Management Facility are near the project site. McClellan-Palomar is a general aviation airport in the City of Carlsbad approximately '/, mile southwest of the site. Airport noise levels are below 60 dB A CNEL at the project site. The North County Waste Management Facility is located approximately 410 feet south of the site. Noise resulting from activities occurring at this facility also contributes to the existing noise environment. 3.2 NOISE SENSITIVE RECEPTORS Several noise sensitive areas were identified in the vicinity of the project. These noise sensitive receptors include the La Posada de Guadalupe de Carlsbad Shelter and the Carlsbad Oaks North Habitat Conservation. Figure 3 depicts the locations of these nearby noise sensitive areas. 3.3 SOUND LEVEL MEASUREMENTS A series of short-term, Y,-hour sound level measurements were conducted on April 22, 2008. The purpose of the measurements was to quantifY the existing noise environment in the vicinity of the project site and to characterize noise sensitive receptors that may be exposed to sound level increases as a result of the project. These receptors include the Carlsbad Oaks North Habitat Conservation Area (ML2) located approximately 270 feet southeast of the project site and the La Posada de Guadalupe de Carlsbad Shelter (ML4) located approximately 445 feet northwest of the project site. Measurements (MLl & ML3) were conducted within the proposed project site to also quantify the existing onsite noise environment. MLI was conducted 30 feet north of the Orion Way centerline and 305 feet east of the Orion Street centerline near the southern boundary of the project. ML3 was conducted near the northeastern comer of the project. ML3 was conducted 42 feet south of the Orion Street centerline and 45 feet east of the centerline of Orion Way. A Larson Davis Model 820 American National Standards Institute Type I Integrating Sound Level Meter was used as the data-collection device. The meter was mounted to a tripod approximately 5 feet above ground to simulate the average height of the human ear. The Y,-hour measurements were performed on K:\NOlSE\095413001\RepOrt\First Responders Facllty Noise An~iyo,;ls Report 09-IB·200S.doc 6 I I I I I I I I I I I Wednesday, April 22, 2008, between 9:15 a.m. and 12:45 p.m. The sound level meter was calibrated before and after the measurement periods. The measurement results are summarized in Table 2 and correspond to the locations depicted on Figure 3. A review of the table shows that the measured sound level was 55.7 dBA Leq at Measurement Location l (MLl), 56.6 dBA Leq at ML2, 57.5 dBA Leq at ML3, and 54.7 dBA Leq at ML4. Noise sources that contributed to the noise environment included vehicular traffic on Orion Way, Orion Street, North County Waste Management Facility activities, and aircraft on approach to McClellan-Palomar Airport.

The Carlsbad Oaks North Habitat Conservation Area would be impacted primarily by traffic entering Orion Way. Project-generated a.m. peak hour traffic volumes for vehicles entering the facility would be approximately 80 vehicles (LSA Associates, Inc. 2008). The La Posada de Guadalupe de Carlsbad Shelter would be exposed to project-generated traffic leaving the facility traveling northbound on Orion Street. Existing a.m. peak hour traffic volumes for vehicles traveling northbound on Orion Street is approximately 32 vehicles. Existing plus project a.m. peak hour traffic volumes for vehicles leaving the facility traveling northbound on Orion Street would be approximately 112 vehicles (LSA Associates, Inc. 2008, Page 5, Table E). A traffic mix of cars only was assumed for both Orion Street, due to its small capacity and traffic volume. The Federal Highway Administration's (FHWA) Traffic Noise Model version 2.5 was used to calculate traffic noise levels. The modeling analysis considered project buildings, roadway alignments/elevations, estimated average vehicle speed, peak-hour traffic volume, and vehicle mix. Calculations show that the existing plus project 60 dBA CNEL noise contour would occur along the edge of Orion Way; therefore existing plus project traffic noise levels at the Carlsbad Oaks North Habitat Conservation Area would be negligible. Existing plus project noise levels at the La Posada de Guadalupe de Carlsbad Shelter would be 52 dBA Leq. The project-generated noise level increase would be approximately 5 dBA but would be below the City's 60 dBA CNFL threshold of significance. Vehicular traffic calculations are summarized in the Appendix. 4.2 OPERATIONAL IMPACTS Indoor and outdoor training activities may take place at any hour but will typically occur between the hours of 7:00 a.m. and I 0:00 p.m. Training activities are normally planned when firefighters are on their respective shifts or when they are conducting an academy for new recruits. As such, there are no set times, days or weeks when training would occur. Outdoor training area locations are depicted on Figure 3. 4.2.1 Outdoor Training Activities Outdoor activity associated with Standard Fire Fighting Training includes noise generated by voices which would be elevated during command and the noise produced from the truck pump, which would be needed to produce or increase water pressure through the attack hose lines. Noise from voice commands would be consistent with the activities currently occurring onsite and in the project area. Noise generated from the truck pump is estimated to be as high as 70 dBA at 50 feet from the source. These training activities would take place near the Residential and Commercial Burn Prop Facilities. For training (evolutions) the total time from entry to fire suppression would be about I 0 minutes in duration. K:\NOISE\095413001\Report\First Responders Facility Noise AMiysls Reprnt 09·1B·200l!.doc 8 I I I I I I I I I I I I I I I I I I I Depending on the number of personnel to be trained, these evolutions could be repeated several times before the truck pumps are shut down. For Multiple Company Training events, the noise and activity level would increase because there would be two or three trucks present at the site, all of which would be performing concurrent activities as described above. These events would be rare because of the number of resources taken offline to perform. Noise levels associated with these events are estimated to be as high as 75 dBA at 50 feet from the activity. Car Extrication Training normally would occur during daylight hours but occasionally at night with truck lights used for illumination. The "Jaws of Life" machinery used to pry open the cars would be the main noise source. Noise levels associated with this machinery are estimated to be less than 70 dBA at 50 feet from the source. These training activities would occur north of the Residential Bum Prop Facility near the northern project boundary. Like Car Extrication Rescue, Trench Rescue training normally occurs during daylight hours but would occasionally occur at night with truck lights once again used for illumination. The trench would be an approximately eight-foot deep sub-grade trench. The training would involve noise-making activities such as placement of shoring devices, tripod bracing for hoisting, and the use of pneumatic tools for preparation and ground work. Maximum noise levels associated with pneumatic tools are estimated to be as high as 70 dBA at 50 feet from the activity. Trench Rescue training activities would take place near the northeast cul-de-sac near the eastern project boundary. Driver's Training on the open rodeo grounds located in the northwest portion of the site would involve slow maneuvers on a course with a maximum speed of approximately I 0 mph. Noise associated with these operations would be negligible due to the slow speeds of the vehicles. The driver's training would be almost always performed during the daylight hours to allow optimum visibility. Acoustical calculations were performed to estimate sound level from training activity at the La Posada de Guadalupe de Carlsbad Shelter, based on a worst-case line-of-sight assumption with no intervening structures. Noise from the equipment was considered a point source. Sound from a point source generally decays at a rate of 6 dBA per doubling of distance from the source. This is a logarithmic relationship describing the acoustical spreading of a pure, undisturbed spherical wave in air. The rule applies to the propagation of sound waves with no ground interaction. Sound levels were calculated using the formula SPL, = SPL, -20 log(~:) where SPL, SPL, . d, d, known sound level, desired sound level, known distance, and desired distance. Line of sight training activity noise levels at the La Posada de Guadalupe de Carlsbad Shelter and at the Carlsbad Oaks North Habitat Conservation Area would result in a noise level of approximately 56 dBA and 60 dBA respectively. Noise attenuation resulting from elevation changes, intervening structures and the 6-foot wall proposed along the site perimeter would reduce the noise by at least 15 dBA. Therefore, sound levels would be expected to be less than 60 dBA CNEL at these locations. Outdoor training activity noise impacts from the project are less than significant. K:\NOISE\095413001\Report\First Respanders Facility Noise AnalysiS Report 09·111·200/l.doc 9 I I I I I I I I I I I I I I I I I I I 4.2.2 Indoor Training Activities The indoor shooting range is located within the Public Safety Facility which would run along the southern property line. The exterior wall assembly would consist of 12" Rubber Dura-Block, 2" Rubber Dura- Panel, W' steel, 8" fully grouted C.M.U., 2" rigid insulation, l" airspace, and a layer of 4" veneer exterior masonry. The roofing assembly would be a steel frame with a 5" concrete slab on a 3" metal deck with 3- W' rigid insulation roofing system. Duct silencers for HV AC and supply and exhaust fans are to be used to reduce exit sound levels into the mid-50 dBA range. The exterior wall and roofing assemblies would be expected to achieve the necessary noise reduction and meet the STC requirements needed to ensure that noise from gun range is not audible outside the facility. Although noise impacts from the indoor gun range will be less than significant, it is recommended that the duct silencers for the HV AC and supply and exhaust fans reduce exit noise to less than 45 dBA to ensure inaudibility. 4.3 CONSTRUCTION Construction activities at the proposed site would result in a short-term, temporary increase in the ambient noise level. The increase in noise level would be primarily experienced close to the noise source. The magnitude of the impact would depend on the type of construction activity, noise level generated by various pieces of construction equipment, duration of the construction phase, and distance between the noise source and receiver. Sound levels of typical construction equipment range from approximately 65 dBA to 90 dBA at 50 feet from the source (U.S. Environmental Protection Agency [U.S. EPA]l97l). This project would implement conventional construction techniques and equipment. Standard equipment such as scrapers, graders, backhoes, loaders, tractors, cranes, and miscellaneous trucks would be used for construction of most project facilities. Specialized construction activities such as pile driving and blasting are not anticipated for this project. Construction activity and delivery of construction materials and equipment would be limited to the hours between 7:00 a.m. and 7:00 p.m. A construction phasing plan has not been developed at this time; therefore, only a general estimate of construction noise levels can be provided. Acoustical calculations were performed to estimate the sound levels associated with construction operations at the La Posada de Guadalupe de Carlsbad Shelter and at the Carlsbad Oaks North Habitat Conservation Area as described for training activities. Line of sight construction noise at the La Posada de Guadalupe de Carlsbad Shelter and at the Carlsbad Oaks North Habitat Conservation Area would result in a noise level ranging from approximately 46 to 71 dBA and 49 to 74 dBA respectively. Noise attenuation resulting from elevation changes, intervening structures and the 6-foot wall proposed along the site perimeter would reduce the noise by at least 15 dBA. Therefore, sound levels would be expected to be less than 60 dBA CNEL at these locations. Construction noise impacts from the project are less than significant.
