(Noise Suppression Plan in CMP Folder) 2/27/2018 City of Aspen Construction Noise Suppression Plan As the General Contractor for this construction project, I JAN STENSTADVOLD hereby agree to the following restrictions and will provide the necessary noise suppression (outlined below), such that it will lesson the impact to the properties within 300 feet of the project located at 320 WEST BLEEKER AVE, ASPEN, CO 81611. I understand that if any construction activities exceed 80 decibels and are not covered by this document I will contact the City of Aspen Environmental Health Department to design a specific noise suppression plan for those activities. JAN STENSTADVOLD Print Name _______________________________ Signature On-site Contact Phone # 970-309-2966 Many activities on construction sites are noisy. Although some noise may be unavoidable, it can often be controlled using improved work practices. Builders should make all reasonable efforts to minimize noise. Noise Suppression plans are required for all construction projects where activities will generate noise that exceeds 80 decibels. Section 18.04.050(A)(2)(d) Hours of operation All construction activity is limited to the following days and times: Monday thru Friday Saturday Sunday 7:30 am to 5:30 pm 9:00 am to 5:00 pm No construction work is allowed Constructions activities producing noise greater than 80 decibels are limited to the following days and times: Monday thru Friday 9:00 am to 5:00 pm Work that is over 80 decibels which by law requires a noise suppression plan will not be allowed for Saturday work that includes but not limited to the use of compressors, generators, jackhammers, power equipment, nail guns, drilling machinery, earth moving equipment and similar loud construction activities. This does not restrict quiet work inside and outside that does not require a power source, including a battery, on Saturday. Construction activity is not allowed during all federal holidays. Due to the congestion in Aspen when town is completely full, noise suppression plans will not be approved for the following dates: Christmas Week (December 25 through Jan. 1), Food and Wine Week in June (Friday thru Sunday), 4th of July day and/or weekend if it falls on a Friday or Monday, and Labor Day weekend. Revised 01/09/2013 2/27/2018 Specific noise suppression requirements for all activities exceeding 80 decibels at a construction site include: 1.Notify neighbors within two hundred fifty (300) feet of the project informing them of the kinds of equipment, expected noise levels and durations of loud work. Including the variation of noise levels during a typical construction days may be helpful. Such notification must be in writing and be done seven (7) days prior to the starting time of the project. Communication with neighbors can prevent complaints from arising, and resolve concerns before there is a problem. Provide a phone number where the foreman can be reached prior to the start of the job. 2.Operate equipment in accordance with manufacturer's specifications and with all standard manufacturers’ mufflers and noise-reducing equipment in use and in properly operating condition. 3.Post notices to inform workers, including sub-contractors, about the basic noise requirements, as well as specific noise restrictions, to the project. 4.Install noise barriers around all equipment/activities specified in Table 1: TYPICAL CONSTRUCTION EQUIPMENT REQUIRING NOISE SUPPRESSION. Noise barriers not only significantly reduce construction noise, but they also provide an extra benefit of “hiding” the noise producing sources, thus increasing a neighbor’s tolerance. (See also the attached list of noise blocking methods for details on approved noise barriers.) 5.Move portable loud equipment including generators, compressors, and cement mixers to different sides of the property to reduce impacts on individual neighbors. What can you do about construction noise? •The use of radios on the site before 8:00 am are not allowed: remind laborers and sub- contractors. •Noise suppression plans will not allow noisy machines such as brick cutters or jackhammers to be operated before 9.00 am. •Noisy equipment such as cement mixers should be placed on the site to maximize the distance from neighboring houses and/or rotate location so as to not impact just one neighbor. Noise levels drop quickly with distance from the source. •All equipment should be properly maintained, with special attention to mufflers and other noise control devices. •Between work periods, builders are required by city ordinance to shut down machines such as backhoes, bobcats, loaders and generators. •When dropping materials from a height—for example, into or out of a truck, or when loading or unloading scaffolding, noise suppression plans require a chute or side baffles. •All vehicular movements to and from the site must only be made during the scheduled normal working hours. This includes off-site noise that is associated with a specific project such as staging of concrete trucks.

Impact Equipment: Impact noise is noise produced from impact or devices with discernible separation in sound pressure maxima. Examples for impact equipment include, but are not limited to; blasting, chisel drops, mounted impact hammers (hoe ram), and impact pile drivers. Impact equipment is the loudest and most intrusive to the neighboring property. The City of Aspen requires that this type activity have the strictest mitigation requirements and requires a customized noise suppression plan specific to the site. General contractors must contact the City of Aspen Environmental Health Department for an application at 970-920-5039. Noise Control • Replace worn, loose, or unbalanced machine parts that cause vibration. • Keep machine parts well lubricated to reduce friction. • Acoustical enclosures and barriers around generators • Sound absorbing material and vibration isolation systems on hand tools • Quiet work practices - use rubber mallets to erect and dismantle formwork.

Environmental Noise Control Introduction 1 1. Introduction The purpose of this study is to provide a noise modeling assessment of the proposed soil stabilization activities associated with the Rutgers Construction project located at 320 W Bleeker Street in Aspen, Colorado. The assessment was performed to ensure the noise levels generated during the soil stabilization activities are in compliance with the noise standards described in the City of Aspen Construction Management Plan Requirements (April 2016). This report provides the results of the predicted unmitigated and mitigated soil stabilization noise levels relative to the relevant noise standards as well as mitigation recommendations needed to comply with the allowable noise levels. Figure 1-1 shows the project site within the City of Aspen. Figure 1-1 Project Site Location 320 W Bleeker Street 2/27/2018 Behrens and Associates, Inc. Environmental Noise Control Noise Fundamentals 2 2. Noise Fundamentals Sound is most commonly experienced by people as pressure waves passing through air. These rapid fluctuations in air pressure are processed by the human auditory system to produce the sensation of sound. The rate at which sound pressure changes occur is called the frequency. Frequency is usually measured as the number of oscillations per second or Hertz (Hz). Frequencies that can be heard by a healthy human ear range from approximately 20 Hz to 20,000 Hz. Toward the lower end of this range are low-pitched sounds, including those that might be described as a “rumble” or “boom”. At the higher end of the range are high-pitched sounds that might be described as a “screech” or “hiss”. Environmental noise generally derives, in part, from a combination of distant noise sources. Such sources may include common experiences such as distant traffic, wind in trees, and distant industrial or farming activities. These distant sources create a low-level "background noise" in which no particular individual source is identifiable. Background noise is often relatively constant from moment to moment, but varies slowly from hour to hour as natural forces change or as human activity follows its daily cycle. Superimposed on this low-level, slowly varying background noise is a succession of identifiable noisy events of relatively brief duration. These events may include the passing of single-vehicles, aircraft flyovers, screeching of brakes, and other short-term events. The presence of these short-term events causes the noise level to fluctuate. Typical indoor and outdoor A-weighted sound levels are shown in Figure 2-1. Detailed acoustical definitions have been provided in Appendix A - Glossary of Acoustical Terms. Figure 2-1 Typical Indoor and Outdoor A-Weighted Sound Levels 2/27/2018 Behrens and Associates, Inc. Environmental Noise Control Noise Standards 3 3. Noise Standards The applicable noise guidelines for the project are contained within the City of Aspen Construction Management Plan Requirements Manual (April 2016). Chapter 11.3: Noise Limits and Suppression Requirements provides the following noise limits: • Projects are limited to 70 decibels (dB) at the property line during the summer on season. • In addition to the decibel limit listed above, projects located on the Mall will be limited to 70 decibels (dB) at the property line during the winter on season. • All other times projects will be limited to 80 decibels (80dB) at the property line. On Season Summer Time Frame: June 1st thru Labor Day On Season Winter Time Frame: November 15th thru March 31st. The proposed soil stabilization activities are expected to begin during the Off Season Time Frame, therefore, the analysis was conducted to ensure compliance with the 80 dBA maximum allowable noise level. The A-weighting scale has been interpreted as applicable to the noise limit to better represent the response to sound of human hearing. 2/27/2018 Behrens and Associates, Inc. Environmental Noise Control Soil Stabilization Noise Modeling 4 4. Soil Stabilization Noise Modeling Noise models representing the proposed soil stabilization activities were constructed with the use of three- dimensional computer noise modeling software. All models in this report were developed with SoundPLAN 8.0 software using the ISO 9613-2 standard. Noise levels are predicted based on the locations, noise levels and frequency spectra of the noise sources, and the geometry and reflective properties of the local terrain, buildings and barriers. SoundPLAN 8.0 software simulates light downwind conditions in all directions to ensure conservative assessments. The modeling results are dependent on equipment and mitigation orientation as indicated. Actual field sound level measurements may vary from the modeled noise levels due to other noise sources such as traffic, other facilities, other human activity, or environmental factors. 4.1 Modeled Soil Stabilization Activities The proposed soil stabilization activities consist of micropiling. Noise models representing the micropiling activities were created to predict the noise levels at the site and adjacent surroundings. The micropiling activities were modeled at one location along the proposed micropiling route for the site as shown in Figure 4-1. The sound power levels for the micropiling equipment included in the modeling are listed in Table 4-1. Sound level data utilized in the micropiling models was based on file data of the Furukawa HCR 900 and associated components. Equipment placement and orientation was coordinated with Rutgers Construction and oriented to minimize noise impact when possible. The predicted modeling results are dependent on equipment and mitigation orientation as indicated.

The requirements indicate that noise levels shall comply with the applicable noise limits as measured at the project property line. The modeled equipment location represents the closest point from the equipment to the property line and signifies the worst-case scenario. The project property line, modeled receiver locations, and modeled equipment location are shown in Figure 4-1. 2/27/2018 Behrens and Associates, Inc.

Noise levels were assessed at the project site property line in accordance with City of Aspen noise regulations. Figure 4-3 shows the Modeled Mitigation Layout. The following mitigation measure is recommended at the construction site to comply with the 80 dBA noise limit: • Approximately 336 total linear feet of 12-foot high acoustical barrier panels with a Sound Transmission Class (STC) rating of at least 25 installed along the perimeter of the project site as shown in Figure 4-3. Additional mitigation recommendations for construction sites are listed below: 1. All equipment should be switched off when not in use. 2. All equipment should be kept in good repair with all worn, loose and unbalanced machine parts to be replaced. 3. Equipment should be placed to maximize the distance between the noisy equipment and the neighboring houses. 4. Construction operations are limited to the hours of 7:30 am to 5:30 pm Monday through Friday and 9:00 am to 5:00 pm on Saturday. Construction on Sunday is prohibited. 5. “Residential” grade mufflers should be fitted to the exhaust outlets of all combustion engines. 6. Where possible, broadband white noise reversing alarms should be used in place of tonal reversing alarms on trucks within the construction site. 2/27/2018 Behrens and Associates, Inc.

Environmental Noise Control Conclusion 12 5. Conclusion Noise models representing the proposed soil stabilization activities at the 320 W Bleeker Street project site were created to assess the noise impact against the 80 dBA noise limit established in the City of Aspen Construction Management Plan Requirements Manual (April 2016). The unmitigated model predicted that the micropiling activity would generate noise levels in excess of 80 dBA at all receiver locations and would, therefore, require sound mitigation. Portable acoustical panels with a height of 12 feet and an STC rating of at least 25 were added along the perimeter of the project site. The resulting mitigated model demonstrated that with installation of the recommended mitigation, the proposed soil stabilization activities are predicted to comply with the noise limit of 80 dBA as established by the City of Aspen Construction Management Plan. 2/27/2018 Behrens and Associates, Inc. Environmental Noise Control Glossary of Acoustical Terms 13 Appendix A - Glossary of Acoustical Terms 2/27/2018 Behrens and Associates, Inc. Environmental Noise Control Glossary of Acoustical Terms 14 Ambient Noise The all-encompassing noise associated with a given environment at a specified time, usually a composite of sound from many sources both near and far. Average Sound Level See Equivalent-Continuous Sound Level A-Weighted Sound Level, dB(A) The sound level obtained by use of A-weighting. Weighting systems were developed to measure sound ina way that more closely mimics the ear’s natural sensitivity relative to frequency so that the instrument is less sensitive to noise at frequencies where the human ear is less sensitive and more sensitive at frequencies where the human ear is more sensitive. C-Weighted Sound Level, dBC The sound level obtained by use of C-weighting. Follows the frequency sensitivity of the human ear at very high noise levels. The C-weighting scale is quite flat and therefore includes much more of the low-frequency range of sounds than the A and B scales. In some jurisdictions, C-weighted sound limits are used to limit the low-frequency content of noise sources. Community Noise Equivalent Level (CNEL) A 24-hour A-weighted average sound level which takes into account the fact that a given level of noise may be more or less tolerable depending on when it occurs. The CNEL measure of noise exposure weights average hourly noise levels by 5 dB for the evening hours (between 7:00 pm and 10:00 pm), and 10 dB between 10:00 pm and 7:00 am, then combines the results with the daytime levels to produce the final CNEL value. It is measured in decibels, dB. Day-Night Average Sound Level (Ldn) A measure of noise exposure level that is similar to CNEL except that there is no weighting applied to the evening hours of 7:00 pm to 10:00 pm. It is measured in decibels, dB. Daytime Average Sound Level The time-averaged A-weighted sound level measured between the hours of 7:00 am to 7:00 pm. It is measured in decibels, dB. Decibel (dB) The basic unit of measurement for sound level. Direct Sound Sound that reaches a given location in a direct line from the source without any reflections. Divergence The spreading of sound waves from a source in a free field, resulting in a reduction in sound pressure level with increasing distance from the source. Energy Basis This refers to the procedure of summing or averaging sound pressure levels on the basis of their squared pressures. This method involves the conversion of decibels to pressures, then performing the necessary arithmetic calculations, and finally changing the pressure back to decibels. 2/27/2018 Behrens and Associates, Inc. Environmental Noise Control Glossary of Acoustical Terms 15 Equivalent-Continuous Sound Level (Leq) The average sound level measured over a specified time period. It is a single-number measure of time-varying noise over a specified time period. It is the level of a steady sound that, in a stated time period and at a stated location, has the same A-Weighted sound energy as the time-varying sound. For example, a person who experiences an Leq of 60 dB(A) for a period of 10 minutes standing next to a busy street is exposed to the same amount of sound energy as if he had experienced a constant noise level of 60 dB(A) for 10 minutes rather than the time-varying traffic noise level. Fast Response A setting on the sound level meter that determines how sound levels are averaged over time. A fast sound level is always more strongly influenced by recent sounds, and less influenced by sounds occurring in the distant past, than the corresponding slow sound level. For the same non-steady sound, the maximum fast sound level is generally greater than the corresponding maximum slow sound level. Fast response is typically used to measure impact sound levels. Field Impact Insulation Class (FIIC) A single number rating similar to the impact insulation class except that the impact sound pressure levels are measured in the field. Field Sound Transmission Class (FSTC) A single number rating similar to sound transmission class except that the transmission loss values used to derive this class are measured in the field. Flanking Sound Transmission The transmission of sound from a room in which a source is located to an adjacent receiving room by paths other than through the common partition. Also, the diffraction of noise around the ends of a barrier. Frequency The number of oscillations per second of a sound wave Hourly Average Sound Level (HNL) The equivalent-continuous sound level, Leq, over a 1-hour time period. Impact Insulation Class (IIC) A single number rating used to compare the effectiveness of floor/ceiling assemblies in providing reduction of impact- generated sound such as the sound of a person’s walking across the upstairs floor. Impact Noise The noise that results when two objects collide. Impulse Noise Noise of a transient nature due to the sudden impulse of pressure like that created by a gunshot or balloon bursting. Insertion Loss The decrease in sound power level measured at the location of the receiver when an element (e.g., a noise barrier) is inserted in the transmission path between the sound source and the receiver. 2/27/2018 Behrens and Associates, Inc. Environmental Noise Control Glossary of Acoustical Terms 16 Inverse Square Law A rule by which the sound intensity varies inversely with the square of the distance from the source. This results in a 6dB decrease in sound pressure level for each doubling of distance from the source. Ln Sound Level Time-varying noise environments may be expressed in terms of the noise level that is exceeded for a certain percentage of the total measurement time. These statistical noise levels are denoted Ln, where n is the percent of time. For example, the L50 is the noise level exceeded for 50% of the time. For a 1-hour measurement period, the L50 would be the noise level exceeded for a cumulative period of 30 minutes in that hour. Masking The process by which the threshold of hearing for one sound is raised by the presence of another sound. Maximum Sound Level (Lmax) The greatest sound level measured on a sound level meter during a designated time interval or event.

Noise Reduction Coefficient (NRC) A single number rating of the sound absorption properties of a material. It is the average of the sound absorption coefficients at 250, 500, 1000, and 2000 Hz, rounded to the nearest multiple of 0.05. Octave The frequency interval between two sounds whose frequency ratio is 2. For example, the frequency interval between 500 Hz and 1,000 Hz is one octave. Octave-Band Sound Level For an octave frequency band, the sound pressure level of the sound contained within that band. One-Third Octave The frequency interval between two sounds whose frequency ratio is 2^(1/3). For example, the frequency interval between 200 Hz and 250 Hz is one-third octave. One-Third-Octave-Band Sound Level For a one-third-octave frequency band, the sound pressure level of the sound contained within that band. Outdoor-Indoor Transmission Class (OITC) A single number rating used to compare the sound insulation properties of building façade elements. This rating is designed to correlate with subjective impressions of the ability of façade elements to reduce the overall loudness of ground and air transportation noise. Peak Sound Level (Lpk) The maximum instantaneous sound level during a stated time period or event. 2/27/2018 Behrens and Associates, Inc. Environmental Noise Control Glossary of Acoustical Terms 17 Pink Noise Noise that has approximately equal intensities at each octave or one-third-octave band. Point Source A source that radiates sound as if from a single point. RC Curves (Room Criterion Curves) A system for rating the noisiness of an occupied indoor space. An actual octave-band spectrum is compared with a set of standard RC curves to determine the RC level of the space. Real-Time Analyzer (RTA) An instrument for the determination of a sound spectrum. Receiver A person (or persons) or equipment which is affected by noise. Reflected Sound Sound that persists in an enclosed space as a result of repeated reflections or scattering. It does not include sound that travels directly from the source without reflections. Reverberation The persistence of a sound in an enclosed or partially enclosed space after the source of the sound has stopped, due to the repeated reflection of the sound waves. Room Absorption The total absorption within a room due to all objects, surfaces and air absorption within the room. It is measured in Sabins or metric Sabins. Slow Response A setting on the sound level meter that determines how measured sound levels are averaged over time. A slow sound level is more influenced by sounds occurring in the distant past that the corresponding fast sound level. Sound A physical disturbance in a medium (e.g., air) that is capable of being detected by the human ear. Sound Absorption Coefficient A measure of the sound-absorptive property of a material. Sound Insulation The capacity of a structure or element to prevent sound from reaching a receiver room either by absorption or reflection. Sound Level Meter (SLM) An instrument used for the measurement of sound level, with a standard frequency-weighting and standard exponentially weighted time averaging. Sound Power Level A physical measure of the amount of power a sound source radiates into the surrounding air. It is measured in decibels. 2/27/2018 Behrens and Associates, Inc. Environmental Noise Control Glossary of Acoustical Terms 18 Sound Pressure Level A physical measure of the magnitude of a sound. It is related to the sound’s energy. The terms sound pressure level and sound level are often used interchangeably. Sound Transmission Class (STC) A single number rating used to compare the sound insulation properties of walls, floors, ceilings, windows, or doors. This rating is designed to correlate with subjective impressions of the ability of building elements to reduce the overall loudness of speech, radio, television, and similar noise sources in offices and buildings. Source Room A room that contains a noise source or sources Spectrum The spectrum of a sound wave is a description of its resolution into components, each of different frequency and usually different amplitude.
