Contractor will recycle materials where applicable. Materials, both conventional and construction
related will be recycled on site in accordance with City of Aspen Municipal Code 26.575.060.
These materials will not be disposed of in the trash. All trash receptacle containers that is used
for food refuse on-site will be constructed in such a manner as to render it bear-proof and will be
removed daily by Contractor. All containers will be adequately covered at all times until
transferred to the landfill. Accumulated debris, litter, and/or trash will be contained so as not to
blow or scatter onto adjoining properties. There will be no construction trailer on site. See
attached CMP site plan for the location of one construction toilet.
6.0 Traffic Control
6.1 General
The scope of this project should not necessitate a traffic control plan.
6.2 Haul Routes

Engineering Department. All deliveries will be scheduled through the contractor with a (48)
hours’ notice. Any unscheduled deliveries may be turned away. Deliveries will avoid peak traffic
times for city roads (8am-10am & 3pm-5pm) and there will be a maximum of (2) delivery
vehicles onsite at any one time due to the space restrictions of the site and access road. It is not
3/04/2018
anticipated, but if there is traffic control required for major deliveries it will be coordinated with
the City of Aspen Engineering and Parking Departments.
All required traffic control personnel and signage will be in place prior to vehicle entrance. The
Contractor will be responsible for dispatching all offsite delivery vehicles to the onsite staging
area and coordinate prompt offloading to prevent backup of vehicles in the public right-of-way.
No road closures will be necessary for the proposed improvements. Delivery vehicles and all
other onsite vehicles are not allowed to idle for more than five (5) minutes.

Construction Noise Suppression Plan
As the General Contractor for this construction project, I Aspen Skiing Company 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 Ajax Ski
Mtn-Water Tan Aspen. 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.

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.
3/04/2018
Specific noise suppression requirements for all activities exceeding
80 decibels at a construction site include:
1. Notify neighbors within two hundred (200) 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.

Noise Blocking Methods
Contractors shall require all subcontractors and vendors to use:
• Quieter vs. Louder equipment
• “Residential” grade combustion engine exhaust silencers
• Electrical vs. pneumatic hand power tools: All pneumatic tools operated in the City of
Aspen must be fitted with an effective silencer on their air exhaust port.
• Hydraulic vs. air powered rock drills
• “Silenced” pile drivers vs. Diesel pile drivers
In general, noise reduction equipment and materials may include, but not be limited to:
1. Shields, shrouds, or intake and exhaust mufflers.
2. Noise-deadening material to line hoppers, conveyor transfer points, storage bins,
or chutes.
3. Noise barriers using materials consistent with the Temporary Noise Barrier
Materials Section.
4. Noise curtains
5. Plywood with concrete blankets at the height of the equipment and that it
surrounds the activity such that it directs noise up more than out from the
property.
6. Portable three sided enclosures made out of plywood to move with the activity
such as jack hammering.
7. Internal combustion engines are to be fitted with a suitable muffler in good repair.
Specific Equipment:
Generators: The local power grid shall be used wherever feasible to limit generator noise. No
generators larger than 25 KVA shall be used and, where a generator is necessary, it
shall have maximum noise muffling capability.
Backup Alarms: All equipment with backup alarms operated by the Contractor, vendors,
suppliers, and subcontractors on the construction site shall be equipped with
either audible self-adjusting ambient-sensitive backup alarms or manually-
adjustable alarms. The ambient-sensitive alarms shall automatically adjust to a
maximum of 5 dBA over the surrounding background noise levels. The
manually-adjustable alarms shall be set at the lowest setting required to be
audible above the surrounding noise. Installation and use of the alarms shall be
consistent with the performance requirements of the current revisions of Society
of Automotive Engineering (SAE) J994, J1446, and OSHA regulations.
Compressors: The unit with the lowest noise rating which meets the requirements of the job
should be used where work is conducted in the City of Aspen, installed with
mufflers and/or enclosed in a noise barrier.
3/04/2018
Jackhammer: All jackhammers and pavement breakers used on the construction site shall have
exhaust systems and mufflers that have been recommended by the manufacturer
as having the lowest associated noise and shall be enclosed with shields or
acoustical barrier enclosures.
Concrete crushers or pavement saws: Pre-augur pile holes to reduce the duration of impact or
vibratory pile driving and tie to local power grid to
reduce the use of generators and shall be enclosed with
shields or acoustical barrier enclosures.
Pneumatic hand power tools: All pneumatic tools operated in the City of Aspen must be fitted
with an effective silencer on their air exhaust port.
Temporary Noise Barrier Materials:
Temporary barriers shall be constructed of 3/4-inch Medium Density Overlay (MDO) plywood
sheeting, or other material of equivalent utility and appearance having a surface weight of 2
pounds per square foot or greater. The temporary barriers shall be lined on one side with glass
fiber, mineral wool, or other similar noise curtain type noise-absorbing material at least 2-inches.
The materials used for temporary barriers shall be sufficient to last through the duration of the
construction project, and shall be maintained in good repair. Prefabricated acoustic barriers are
available from various vendors. An equivalent barrier design can be submitted in lieu of the
plywood barrier described above.
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.
