1.0 GENERAL
1.1 PURPOSE
The purpose of this Construction Management Plan Manual is to provide a consistent
policy under which certain physical aspects of construction management will be
implemented. The elements contained in this document are related to the development
process. It is intended that they apply to both public and private work designated
herein.
These standards cannot anticipate all situations. They are intended to assist, but not to
substitute for competent work by design and construction professionals. The City of
Aspen does not intend to limit any innovative or creative efforts that could result in
better quality, greater cost savings, or both. Any proposed departure from the manual
will be judged on the likelihood that such variance will produce a comparable result,
adequate for the user and City resident over the duration of the improvement/project.
If the project changes ownership or contracting services change, the City Engineering
Department must be notified, and must agree to comply with an approved CMP in
writing. Any departure from the approved CMP must be submitted in writing and
approved by the City Engineer. The approved construction management plan must be
kept onsite.
1.2 APPLICABILITY
This manual shall govern the construction and development of all public and private
construction projects in the City of Aspen. These regulations shall apply to all
commercial, industrial, residential, and mixed use developments which disturb 1000 SF
or greater or require demolition, improvement, or renovation (interior and/or exterior)
of 400 SF or greater within any twelve-month period.
1.3 DEFINITIONS AND TERMS
Construction Management Plan – A Construction Management Plan is a combination of
diagrams, documents, drawings, and specifications that clearly define the steps that will
be taken to demonstrate how the impacts to the community will be minimized. How the
impacts associated with any construction project will be managed. Herein described as
“Plan” throughout the remainder of this policy.
Construction Mitigation Officer – An appointed employee of the City of Aspen whose
charge is to ensure that all aspects of a Construction Management Plan are followed,
and to further ensure that the impacts associated with construction activities within the
City of Aspen are effectively managed and impacts associated with those projects are
the least necessary to accomplish the project.
02/22/2019
2
Disturbance Area – A portion of land where topsoil or native soils have been removed
for purposes of construction (development).
Best Management Practices (BMP’s) – Schedules of activities, prohibitions of
practices, maintenance procedures, and other management practices to prevent or
reduce the pollution of waters of the state. BMP’s also include treatment
requirements, operating procedures, and practices to control site runoff, spillage or
leaks, waste disposal, or drainage from material storage.
Tree Dripline and Protection Zone - Use the longest branch of the tree as a radius
from the center of the tree and make a circle. The circle is then defined as the
dripline and thus is the tree protection zone.
Final Stabilization – Uniform vegetative cover has been established with a density of
at least 70 percent of pre-disturbed levels.
Major Impact: Major projects as defined by the Urban Runoff Management Plan
(URMP).
Moderate Impact: Minor project as defined by the URMP and located in the CRA.
Minor Impact: Minor project as defined by the URMP and located outside of the
CRA.
URMP Triggers can be found in Table 1.1 of the URMP. A link to the table can be

Additional restrictions on construction hours and encroachments will be applied for
Aspen Special Events. Examples of events that will require additional restrictions
include the USA Pro Cycling Challenge and the Farmer’s Market.
Additional restrictions on construction hours will also be applied based on the project’s
specific impacts on adjoining properties. This includes limiting work during sales events
(for a maximum of two sales events per year), maintaining site lines to these businesses,
and providing signage on the construction site advertising the adjacent business. For
example, if an adjoining business has an event (such as a semiannual sale) the project
will accommodate this adjoining business to ensure the construction activities do no
adversely affect that business’s event.
4.3 SEQUENCE (PHASING) OF CONSTRUCTION
A construction schedule including all project phasing, with item details, and
specific item completion dates or duration of phasing is required.
02/22/2019

4.4 ADJOINING PROPERTIES
No person shall excavate on land close enough to a property line to endanger any
adjacent public street, sidewalk, and alley, other public or private property, or easement,
without supporting and protecting the property from any damage that might result from
construction operations.
Additionally the project must identify which adjoining properties will be most affected
by the project and how the project intends on mitigating the impacts to those properties.
This includes identifying adjacent businesses and understanding what events (such as
sale events) and programs that business has scheduled throughout the year. The project
will be required to work with the adjoining properties to mitigate impacts to their events
and programs. This also includes maintaining sight lines to adjacent businesses.
Lastly the needs of adjoining construction projects must not be compromised.
4.5 PROJECT FENCING
All construction areas shall have a non-removable construction fence or other approved device
securely placed around the areas to be protected. The fence shall be six feet (6') in height and

5.0 SITE AND RIGHT OF WAY MANAGEMENT
5.1 RIGHT OF WAY MANAGEMENT PLAN
A Plan outlining the use the of the Right-of-way (ROW) must be submitted as part of
the CMP. This plan will identify areas of encroachments including the use of parking
spaces for the project. The use of the ROW will be limited according to the
requirements outlined in Section 5.6.
5.2 EMERGENCY VEHICLE ACCESS AND ORDINANCE 35
The contractor shall maintain continuous emergency vehicle access, on and around site,
including but not limited to police, fire, and ambulance services. This includes projects
adjacent to roads and alleys.
5.3 CONSTRUCTION PARKING DETAILS
Specific construction parking spaces/areas may be requested for use by craftsman,
subcontractors, and contractors involved in the site construction process. Prior to the
City allowing for construction parking spaces, the project must demonstrate that it has
minimized the amount of vehicles traveling to the site. This will be demonstrated
through Traffic Demand Management (TDM) Plan. A site’s TDM plan will consist of
the following:
Minor Impact – Select one or more of the following
Moderate Impact – Select two or more of the following
Major Impact – Select three or more of the following
Project-Sponsored Vanpool - Employer-sponsored vanpool programs entail an
employer purchasing or leasing vans for employee use, and subsidizing the cost
of program operations and administration. The driver usually receives personal
use of the van, often for a mileage fee. Scheduling is within the employer’s
purview, and rider charges are normally set on the basis of vehicle and operating
cost. The successful project will implement an employer-sponsored vanpool,
thus reducing the need for SOV trips to and from the worksite. Note: To receive
credit, project staff must park and be picked up no further up valley than the
Brush Creek Intercept Lot. Enforcement: A vanpool route and schedule should
be submitted as part of the CMP. Staff may audit the route to ensure its
presence.
02/22/2019
8
Project Shuttle - Offering employees a customized trip to work via private
shuttle reduces the need for SOV trips. The successful project will provide a
convenient, regularly scheduled employee shuttle from a Park & Ride, Intercept
lot or other identified pick up points to the worksite. To receive credit, project
staff must park and be picked up no further up valley than the Brush Creek
Intercept Lot. Enforcement: A shuttle route and schedule should be submitted
as part of the CMP. Staff may audit the route to ensure its presence.
Carpool Program – The successful project will require employees to form
carpool groups of two or more adults to reach the worksite. To receive credit,
carpools should originate no further up valley than the Brush Creek Intercept
Lot. Enforcement: carpool passes should be kept may be requested.
Transit Fare Subsidy - The successful project will provide fully subsidized daily
or monthly public transit passes for the RFTA valley system. Enforcement:
Records of the purchase and subsidies must be kept and may be requested.
Parking Cash-out - The term cash-out is used to describe the provision of
employee choice of forgoing their current subsidized/free parking for a cash
payment equivalent to the cost of the parking space. The successful project will
require provide no free parking for workforce and will provide a cash subsidy to
those who in Aspen City limits via transit, vanpool, bicycle or walk modes.
Enforcement: records of the parking cash out must be kept and may be
requested.
Customized Program – This option allows for the project to propose a measure
not listed above. If this option is chosen, a narrative should appear below and
must include the following information for staff review:
*description of measure
*justification of measure
*route and schedule if applicable
*enforcement options
After demonstrating that the project has minimized the amount of vehicles traveling to
the site, through the use of a TDM (which includes the measures above), the City will
allow minimal onsite parking
No construction parking will be permitted within the free two-hour residential parking areas
without a valid permit.
5.4 STAGING AREAS
The Plan shall specify construction staging area locations. Alleyways are preferred
short term staging locations without blocking access to neighboring properties. The
number of truckloads expected to and from the site should be estimated (including
soil hauling and materials transport). The timing and duration of the transport
02/22/2019
9
vehicles should also be noted.
City of Aspen personnel can limit project staging locations, number of trucks,
and duration of operations depending on project location and site surroundings.
Projects that require crane operations and have little or no setbacks are required to use
a tower crane. The City prefers electric type cranes to reduce noise and fumes.
Right-of-Way encroachments are used as a last resort in all cases. In the case where
a ROW encroachment occurs, a permit must be obtained from the City Engineering
Department. Refer to Section 5.5 for limitations on the use of the ROW.
5.5 RIGHT OF WAY LIMITATIONS
a. The following activities may require the use of the ROW:
Temporary construction of guardrail, pedestrian walkways, scaffolds, protective
canopies, etc..
Temporary storage of materials, merchandise, commodities, construction
materials, etc..
Park or stage and operate construction equipment, crane, bulldozer, skid steer,
etc..
Temporary placement of a field office, dumpster, loose material container, or
construction fencing
Earth retention methods and associated removal
b. The requests for the use of the ROW (i.e. encroachments) are reviewed by the
Engineering Department. The follow factors are considered before granting any use
of the ROW:
Location: Depending on location, there will be limitations on the use of the
ROW. The core area in particular has on season restrictions. Refer to Section 5.5
(c).
Size: The encroachment must occupy as small a footprint as applicable and may
not affect safe lane widths or bus routes. Additionally the encroachment may not
interfere with City snow removal process. If lane closures are anticipated we
recommend that the applicant complete the work before 10am to lessen the
impact.
Safety: The encroachment must accommodate pedestrians. Conflict between
pedestrians and construction traffic must be minimized. Additionally, all
encroachments shall ensure sight distances of 35 feet from the intersection. There
must be no overhead hazards (crane swing, etc...) and there must be adequate
room for Emergency Response.
Schedule: Aspen has many re-occurring special events scheduled throughout the
year. Some encroachments may be limited or not approved based on impacts to
these events. Holidays and special events that affect ROW closures in the core
area include, but may not be limited to: Food and Wine (mid June), USA Pro
Cycling Challenge (mid August), Saturday Farmer’s Market (mid June thru mid
October), Holiday/Christmas Week and the July 4th Parade.
02/22/2019
10
Aesthetics: Consideration should be given to the aesthetics, public information,
and signage for adjacent businesses, site barricades, fencing, enclosed walkways
etc. can be more than barren plywood walls. Whether its artwork, information
about the project or for local businesses there is an opportunity to minimize the
aesthetic impact.
c. Limitations for Encroachment Zones: There are seasonal limitations for temporary
encroachments (refer to Appendix F for zone designations). These limitations
include the following:
i. Red Zone: Five foot encroachment allowed on the mall during the on
season. For areas abutting a street, a 15 foot encroachment will be
allowed during the on season. For corner lots, only one side of the
building will be permitted an encroachment during the on season. Sites
will be limited to one on season encroachment.
ii. Orange Zone: A fifteen foot encroachment will be allowed during the
on season. For corner lots, only one side of the building will be
permitted an encroachment during the on season. Sites will be limited
to two on season encroachments.
iii. Yellow Zone: A fifteen foot encroachment will be allowed during the
on season. For corner lots, only one side of the building will be
permitted an encroachment during the on season. Sites will be limited
to three on season encroachments.
iv. The City may allow for larger encroachments if the site can
demonstrate the benefits of doing so. For sites requesting larger
encroachments they must not only demonstrate the benefit to the City
but also submit two construction schedules one with the larger
encroachment request and one without.
d. On Season Time Frame: On seasons are defined as June 1st thru Labor Day and
November 15th thru March 31st.
5.6 CONSTRUCTION TRAILER, MATERIALS STORAGE, AND WASTE MANAGEMENT
As specified in Section 5.1, construction trailer, job materials storage, portable
restrooms, waste management and recycling container locations shall be clearly
designated on the project site plan. Loose job material storage is not allowed in
ROW under any circumstance.
The City of Aspen Engineering Department strongly recommends job trailer, waste
management containers, and portable restrooms be stored on private property and not
within City ROW.
The City of Aspen requires recycling of construction materials. In instances where
recycling containers cannot be accommodated onsite, the City Engineering
Department will consider locating recycling containers within public ROW where
feasible. The encroachment permit fee will be waived if it pertains to recycling
02/22/2019
11
containers. If at any time such a container is not being used for recycling operations,
the property owner will be responsible to pay at least three months calculated land
lease fee.
The City of Aspen requires recycling of materials, both conventional and
construction related, according to this document and City of Aspen Municipal Code
Title 12. A waste management plan must be submitted to the City prior to beginning
demolition or construction. Recycling requirements included in this section do not
supersede project specific Building Code requirements. Refer to Appendix H for the
waste management plan requirements.
Project site conventional recycling of co-mingled materials (plastics #1-#7, tin,
aluminum, and glass), and cardboard must have an assigned space/area and be
separated on-site during the project. Sites must comply with Colorado and
Aspen landfill bans, i.e. no disposal of electronic waste, fluorescent light bulbs,
hazardous waste or yard waste. These materials may not be disposed of in the
trash.
During the demolition phase of a project, deconstruction related activities are
required (recycling and/or salvaging of material such as wood products, drywall,
flooring, etc.). Concrete and scrap metals must be sorted and kept separate on-site
and must have an assigned space/area.
Field inspections will occur throughout the permit process. If sorting of materials is
not occurring onsite, other means of verification may be provided to City of Aspen as
deemed appropriate. Acceptable verifications include (but are not limited to) a receipt
from the recycling facility, an invoice from the company receiving the materials for
recycling/salvaging or other proof the materials are being repurposed or recycled.
Per municipal code (12.08.010), any dumpster or other trash receptacle that is used
for food refuse must be constructed in such a manner as to render it bear proof. All
containers shall be adequately covered at all times until transferred to the landfill.
The City of Aspen municipal code states it shall be unlawful to permit accumulated
debris, litter, or trash on any construction site to blow or scatter onto adjoining
properties (12.04.020).
An onsite hazardous material spill cleanup kit is required, as specified by the
City Engineer, that contains, at a minimum, a 25 pound bag of Floor-Dri (or
equal), absorbent pads, and other spill kit materials.

of the soils.
3. Soils must be contained and covered at all times unless actively being
worked. Working will be defined as moving, compacting,
backfilling, exposing, or grading the soils at least once in a sixty
minute period. If any stockpile of soil is to be left for more than sixty
minutes it must be contained and covered.
02/22/2019
14
4. Containment and Covering is required. This can be accomplished
through the use of a non-permeable tarp placed below the
stockpile and the same type of material shall be used to cover the
stockpile.
5. After completion of the project an uncontaminated soil cap will
be required. This cap shall consist of twelve inches of clean fill
or gravel. This can also be accomplished by paving the area with
asphalt or concrete.
6. In order to obtain a “clean letter” from the City of Aspen, which, will
be required prior to the release of the Certificate of Occupancy, all
of the above conditions must be met.
9.0 FUGITIVE DUST CONTROL
9.1 FUGITIVE DUST CONTROL PLAN
All projects that result in fugitive dust emissions must submit a fugitive dust control
plan and file an application for a construction permit with the Colorado Department of
Public Health and Environment.
The approval of a Dust Prevention and Control Plan does not relieve the owner or
contractors of the responsibility to implement whatever additional measures may
be required by the City Engineer to properly prevent and control dust.
9.2 REQUIREMENTS
The plan shall demonstrate that the discharge of dust from the construction site will
not occur, or can be controlled to an acceptable level depending on the particular site
conditions and circumstances.
1. The plan shall address site conditions during construction operations,
after normal working hours, and during various phases of
construction.
2. The plan shall include the name and the 24 hour phone number of
a responsible party.
3. If the importing or exporting of dirt is necessary, the plan shall also
include the procedures necessary to keep the public streets and
private properties along the haul route free of dirt, dust, and other
debris.
4. When an entire project is to be graded and the subsequent
construction on the site is to be completed in phases, the portion of
the site not under construction shall be treated with dust preventive
substance or plant materials and an irrigation system.
5. All phased projects shall submit a plan demonstrating that dust will
not be generated from future phase areas.
02/22/2019
15
For all construction within the site, the contractor shall have a water truck available
for dust control. Wetting shall be completed once three times a day under dry
conditions or as directed by the City Construction Mitigation Officer.
Vehicle speeds should not exceed 15 mph on construction access roads
and construction site.
10.0 EMISSIONS
10.1 GENERAL
All vehicles and equipment used on site will be properly maintained such that
the engines will function within manufacture’s standards or parameters.
10.2 EMISSIONS FROM DIESEL POWERED ENGINES
Emissions from diesel engines operated within the City of Aspen shall be of a shade
or density no darker than 40% opacity, except for starting motion no longer than 10
seconds or for stationary operation not exceeding 10 seconds.
11.0 NOISE SUPRESSION
11.1 GENERAL
The noise limit for construction is measured at the property line of the construction
site. All construction equipment shall be adequately muffled and maintained to
minimize project noise.
11.2 NOISE SUPPRESSION PLAN
Each site must include information on noise blocking methods, techniques, and
common equipment and activities that require noise suppression (Refer to Appendix
C) to meet the decibel limits below:
Residential projects are limited to 65 decibels (dB) at the property line
during the summer season and 80 dB at the property line all other times of
the year.
Projects located on the Mall are limited to 65 dB at the property line during
the summer and winter season and 80 dB at the property line all other times
of the year.
Projects located in the Core are limited to 75 dB at the property line during
the summer season and 80 dB at the property line all other times of the year.
All other projects will be limited to 80 dB at the property line.
02/22/2019
16
On Season Summer Time Frame: June 1st thru Labor Day
On Season Winter Time Frame: November 15th thru March 31st.
Allowances of an additional 10 dB from the limits above will be made for short
durations. However under no circumstance can the decibel limit exceed 80 dB at the
property line.
Allowance for an excess noise exception from the above limits will be reviewed by
the City Engineer. Criteria for the exemption include:
Where it is in the interest of public safety
Public infrastructure work within the Right of Way
Other activities within the Right of Way where there is no other reasonable
alternative.
Major impact projects that include earth retention are required to have a sound
engineer/consultant model the site plans and insert noise sources and specify noise
mitigation measures to see how noise levels will be reduced. The models should
show the anticipated noise levels at various locations surrounding the project and can
take into account a variety of proposed mitigation measures.
11.3 CONTINUNED NOISE MONITORING
Major construction sites that require earth stabilization will be required to perform
continued noise monitoring. Additionally sites that receive two correction notices or
one red tag for noise violations will be required to provide continued noise monitoring.
This monitoring must be recorded and be made available remotely through on line
access to the City’s Construction Mitigation Officer.
For those sites not required to provide continued noise monitoring but receive verified
noise complaints, the City will install its own continued noise monitor. If the noise
complaints are verified, the site will be required to install its own continued noise
monitor, additionally the city will charge a rental fee for when City’s continued noise
monitor was used for the site.
11.4 REQUIREMENTS FOR ACTIVITIES EXCEEDING 80 DECIBELS
1. Any work producing noise levels over 80 decibels is not permitted to
commence until after 9:00 am and is not permitted on Saturdays.
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.
2. Notify neighbors within three hundred (300) feet of the project
informing them of the kinds of equipment, expected noise levels and
02/22/2019
17
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.
3. 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.
4. Post notices to inform workers, including sub-contractors, about
the basic noise requirements, as well as specific noise restrictions,
to the project.
5. Install noise barriers around all equipment/activities specified in Table
1 of Appendix C. 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.
6. Move portable loud equipment including generators, compressors,
and cement mixers to different sides of the property to reduce
impacts on individual neighbors.
7. The use of radios on the site before 8:00 am is not allowed.
11. 5 SPECIFIC RESTRICTIONS RELATED TO MANUFACTURING ON SITE
Considering that some structures will require an increase in the level of manufacturing
of certain materials in order to complete the desired finish of the structure, additional
restrictions will be placed on those activities. The primary concern is that extending
the duration, for which neighbors are exposed to high levels of noise, could cause
specific unwanted responses. In order to reduce those risk factors to neighboring
properties all manufacturing efforts must be limited on site and when possible shall be
conducted off site, or in such a manner as to not contribute to any long term noise
impacts off of the property.
Manufacturing activities that are in excess of 80 decibels must be accompanied by an
Extended Impact Permit, this will require that the activity is enclosed completely and
limited to 90 days in duration. Air exchange / venting systems shall be installed or
otherwise supplied within the enclosure to provide a clean air source for laborers.
The enclosure must be constructed in a manner which prevents noise and dust from
escaping. This may be accomplished with the use of plastic sheeting to contain dust
and a more dense and rigid material (ply wood, foam insulation boards) erected to
contain sound. Noise levels will be measured at the property line, while facing the
source of the sound, and shall not exceed 65 decibels during working operations.
Activities will be considered manufacturing if alterations to a material that is
readily available on the market are made in order for the material to meet the
02/22/2019
18
needs of the end user. An example of this would be masonry wall construction. If
the all of the stone was delivered as a rough cut product to the site, and each of
the stones were to be cut square and fit into place. In this example the stone
cutting is considered the manufacturing portion of the masonry wall, and should
be conducted off site. This would allow the stones to be cut square and to the
appropriate dimensions and additional work to fit the stones would be permitted
on site.
All work which requires a limited amount of additional manufacturing to achieve the
desired finish (including fitting) shall be conducted between 9am and 5pm, and shall
have an approved noise suppression plan on site, relating to the activity.
12.0 ENFORCEMENT
12.1 CITY CONSTRUCTION MITIGATION OFFICER
A City Construction Mitigation Officer shall be assigned to each construction project.
The City Construction Mitigation Officer will complete random site visits to determine
if the project is following approved Plan and City requirements. The officer is not
intended to take the place of a City of Aspen building inspector.
12.2 CORRECTIVE ACTION
The City of Aspen will enforce construction mitigation corrections as follows:
1. The first corrective action is a verbal warning and explanation of
the violation with a timeframe for completion.
2. The second corrective action is a written warning or correction
notice with timeframe for compliance.
3. Third and final notice is a “Stop Work Order” (red tag). If a stop
work order is issued, no more work can be completed until the
violation is corrected.
4. The City may forgo steps one and two as outlined above and go
directly to the “Stop Work Order” and or a summons and compliant
may be issued for violations under the following circumstances:
Work without a permit
Work that is endangering Public Safety
Work that is endangering Public Health including work that may
affect water quality.
Work on holidays or Sundays (unless the site received an exemption
to work during these times)
The owner and general contractor are responsible for assuring compliance and both
will be charged by summons and complaint in municipal court when necessary. This
applies even if a sub-contractor violates the construction mitigation rules,
02/22/2019
19
Failure to correct violations and/or any threat to public safety could subject the
owner, contractor or both to a maximum penalty of up to a year in jail and/or a fine
of up to $2,650 for each violation. Each day a violation continues is a separate
offense determined by the municipal court.
12.3 INSPECTION REPORTS
The Construction Mitigation Officer will complete construction inspection reports.
All reports are public and will be kept in the City Engineering Department.
13.0 CONSTRUCTION MITIGATION COMMITTEE
Projects seeking exemptions may seek an exemption from project durations, number
of encroachments. These exemptions will be reviewed by the Construction Mitigation
Committee. The committee consists of representatives from the Engineering, Parking
and Building departments. If an exemption is granted then the project will be subject
to the exemption fees as outlined in Title 2.
Considerations for exemptions include impact of exemption on adjacent properties,
duration of exemption and season that exemption is being requested.
14.0 APPEAL PROCESS
Projects may appeal the decision of the Construction Mitigation Committee and / or
the City Engineer. All appeal will be forwarded to the City Manager or their
designee. If the appeal is approved and results in an exemption, then the project will
be subject to the exemption fees as outlined in Title 2.

C – Noise Suppression Plan, Techniques and Equipment
02/22/2019
Revised 11/17/09
Noise Blocking Methods
Contractors shall require all subcontractors and vendors to use:
“Residential” grade combustion engine exhaust silencers
Electrical vs. pneumatic hand power tools
Hydraulic vs. air powered rock drills
“Silenced” pile drivers vs. Diesel pile drivers
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.
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
Shields, shrouds, or intake and exhaust mufflers.
Noise-deadening material to line hoppers, conveyor transfer points, storage bins, or
chutes.
Noise barriers using materials consistent with the Temporary Noise Barrier Materials
Section.
Noise curtains
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.
Portable three sided enclosures made out of plywood to move with the activity such
as jack hammering.
Internal combustion engines are to be fitted with a suitable muffler in good repair.
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.
02/22/2019
Revised 11/17/09
Between work periods, builders are required by city ordinance to shut down machines
such as backhoes, bobcats, loaders and generators.
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.

Height (re-roofing)
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.
Genorators Acoustical enclosures and barriers surrounding equipment
Generators25 KVA:
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.
Hand Tools Sound absorbing material and vibration isolation systems on hand tools
Dismantling
Formwork
use rubber mallets to erect and dismantle formwork
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
02/22/2019
Revised 11/17/09
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.
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.

Stormwater Management During Construction
The purpose of this chapter is to provide requirements and guidance for selecting and
implementing Best Management Practices (BMPs) that will eliminate or reduce the discharge of
pollutants from construction and other land-disturbing activities to local waters. The City of
Aspen Engineering Department is the administrative authority for stormwater management and
erosion prevention and sediment control on construction sites within the City’s jurisdiction. By
policy, Aspen’s requirements for stormwater management during construction are consistent
with those of the Colorado Department of Public Health and Environment’s (CDPHE)
Construction General Permit. The CDPHE Construction General Permit requires a stormwater
management plan (SWMP) for development disturbing greater than one acre of land. However,
Aspen requires a Construction SWMP detailing pollution prevention and erosion prevention
and sediment control measures to be installed for projects that exceed 1000 square feet of
soil disturbance, not just those that disturb greater than one acre. Wherever the City of Aspen
and the CDHPE Construction General Permit requirements are in conflict, the more restrictive
requirements should be applied.
The regulations and guidelines stated in this chapter incorporate information from a variety of
sources including:
The United States Environmental Protection Agency (EPA),
State of Colorado/Colorado Department of Public Health and the Environment (CDPHE),
Urban Drainage and Flood Control District (UDFCD), and
Northwest Colorado Council of Governments (NWCCOG).
It is important to understand that these regulations are subject to change and/or alterations. For
the most up to date copy please contact the City of Aspen Engineering Department.
1.1 PURPOSE
Some construction activities and materials have the potential to pollute our streams, rivers, and
lakes if transported during storms or snowmelt. When construction disturbs land, the soil is
more easily eroded during rainfall, snowmelt, and wind events. Eroded soil, referred to as
sediment, is the greatest pollutant to rivers in Colorado and Aspen. Sediment endangers water
resources by reducing water quality and causing the siltation of aquatic habitat for fish and other
desirable species. Other pollutants, such as petroleum products, metals, and nutrients, easily
attach to soil making sediment even more toxic. Eroded soil also necessitates the cleaning
and/or repair of sewers and ditches and the dredging of water bodies. Therefore clearing,
grading, and vehicle tracking during construction creates the need for erosion prevention and
sediment control on construction sites.
Pollutants other than sediment, such as concrete, solvents, oil, grease and metals, also cause
degradation of water quality in receiving streams, and therefore must also be prevented or
reduced through construction site stormwater management practices.
The City of Aspen requires compliance with the criteria in this chapter in order to
eliminate or reduce the discharge of pollutants in stormwater runoff, and prohibits the
discharge of pollutants from construction sites to the City’s stormwater system. These
criteria should be followed from start of earth disturbance until final landscaping and stormwater
quality measures are effectively in place and accepted by the City. The goal of these
02/22/2019
requirements is to decrease the amount of pollutants entering the stormwater system from
construction and other land disturbing activities.
The following erosion prevention, sediment control, and pollution prevention measures are
designed to safeguard persons, protect property, minimize water quality and other
environmental impacts, and promote the public welfare by guiding, regulating, and assisting the
design, construction, use, and maintenance of any development or activity which disturbs or
breaks the topsoil or results in the movement of earth on land greater than 1000 square
feet in the City of Aspen, Colorado.
1.11 General Requirements
A Construction Stormwater Management Plan (Construction SWMP) must be developed
before a project begins that identifies pollution prevention measures and erosion
prevention and sediment control (EPSC) measures that are appropriate for the actual site
conditions and construction plans for each site – generic plans will not be approved.
The Construction SWMP shall contain a narrative report as well as site plan maps for each
phase of the project. The appropriate schedule of implementation shall be identified as well as
detailed plans shown on plan sheets with appropriate contours for each phase of the project that
will minimize pollution, erosion, and sediment transport.
The Construction SWMP shall be submitted to the City of Aspen as part of the Construction
Mitigation Plan (CMP) and along with the grading and drainage plans in order to obtain a
building or landscape and grading permit. Plans for grading and erosion control should be
considered in the early stages of site planning and drainage design. The Construction SWMP
may have to be modified at the time a final site development plan is prepared in order to better
address the site conditions as the plan changes. This modified plan, the final Construction
SWMP, must be approved by the City of Aspen before ground-breaking activities can occur.
EPSC measures must be designed according to size, slope, and soil type of disturbed drainage
areas in order to prevent erosion and to capture sediment. Potential sources of pollution that
might affect quality of stormwater discharges from the site, and practices that will be
implemented to prevent that pollution, must be identified and described as part of the
Construction SWMP. In addition, sites discharging directly to waters of the state or the City’s
stormwater system might be required to meet stricter requirements as determined by the City
Engineer or City Stormwater Manager.
Implementation of the Construction SWMP (i.e., installation of measures) begins when
construction begins, before the initial clearing, grubbing, and grading operations, since these
activities can usually increase erosion potential on the site. Implementation and maintenance of
pollution prevention measures and EPSC measures are the responsibility of the permit holder
and the project/property owner. Because site conditions will affect the suitability and
effectiveness of pollution prevention and EPSC measures, the SWMP is a dynamic document
that should be referred to frequently, amended and updated as necessary, and kept on site
available for review by City of Aspen staff upon request. The City reserves the right to require
the permit holder and/or property owner to develop and implement additional measures to
prevent and control pollution as needed.
02/22/2019
Pollution Prevention
Pollution prevention for construction within the City of Aspen requires compliance with the
following criteria:
1. Develop Construction SWMP - The Construction SWMP must identify potential
sources of pollution that may reasonably be expected to affect the quality of stormwater
discharging from the site.
2. Practice Good Housekeeping - The Construction SWMP must describe standard
operating procedures and practices that will be implemented to prevent the release of
pollutants to the stormwater system from construction activities.
a. Perform activities in a manner to keep potential pollutants from coming into
contact with stormwater.
b. Prevent spills and leaks (i.e. hydraulic fluid from leaky vehicles or equipment)
c. Use phasing principals to limit areas of disturbance.
3. Contain Materials and Waste – Areas used for staging of construction activities and the
storage of soil, chemicals, petroleum-based products and waste materials, including
solid and liquid waste, shall be designed to prevent discharge of pollutants in the runoff
from the construction site.
a. Store construction, building, and waste materials in designated areas, protected
from rainfall and contact with stormwater run-on and runoff.
b. Dispose of all construction waste in designated areas (e.g. concrete may only be
disposed of in a designated concrete wash-out area), and keep stormwater from
flowing onto or off of these areas.
c. Properly clean and dispose of spilled materials.
4. Dewatering – If it is determined that site dewatering will be required, the permit holder /
and or property owner must obtain a Construction Dewatering Permit for the CDPHE
division of water resources.
Erosion Prevention and Sediment Control
Erosion prevention and sediment control for construction within the City of Aspen requires
compliance with the following criteria:
1. Develop Construction SWMP – The Construction SWMP plan must demonstrate how
stormwater, erosion, and sediment will be handled throughout construction.
2. Control Site Perimeter – Construction activities and their impacts must be controlled
within the limits of the site.
a. Delineate the site perimeter on the plans and in the field to prevent disturbing
areas outside of the project limits.
b. Divert upstream run-on safely around or through the construction project.
Diversions must not cause downstream property damage and cannot be diverted
into another watershed.
c. Construction vehicles and equipment may enter and exit the site at only one
designated access point. This exit must be stabilized with gravel or other
appropriate material throughout the duration of the project.
3. Minimize Disturbed Areas – Construction activities must be scheduled in correct
sequences to minimize the total amount of exposed soil at any given time.
a. Only clear land which will be actively under construction in the near term (e.g.
within the next 1-2 months).
b. Minimize new land disturbance during the spring runoff/snow melt season.
02/22/2019
c. Avoid clearing or disturbing sensitive areas, such as steep slopes and natural
waterways, where site improvements will not be constructed or are not
necessary.
4. Stabilize Disturbed Areas – Disturbed areas must be permanently or temporarily
stabilized as soon as possible, but no later than 14 days after last worked, whenever
active construction is not occurring on that portion of the site. Disturbed areas must be
stabilized by November 15th of each year to minimize erosion and sediment transport
that occurs during spring snow melt.
5. Protect Slopes and Channels – Concentrated stormwater flows shall be avoided or the
conveyance system shall be protected sufficiently to prevent significant erosion.
a. Safely convey runoff from the top of the slope and stabilize disturbed slopes as
quickly as possible.
b. Avoid disturbing natural channels.
c. Ensure the runoff velocity caused by project does not erode channel bottoms.
6. Install and Maintain EPSC Measures – All sites must minimize pollution potential by
installing and maintaining erosion prevention and sediment control measures throughout
the duration of any project.
a. Erosion prevention measures are those BMPs used to limit erosion of soil from
disturbed areas on the site. Erosion prevention measures are required for all
disturbed areas. Examples include: Contour Tracking, Rolled Erosion Control
Products, Hydro Mulching and similar activities.
b. Sediment control measures are those BMPs the limit the transport of sediment
off-site or downstream of disturbed areas. Sediment control measures are
required for all disturbed areas. The most commonly used sediment containment
is silt fencing.
c. Use non-structural and structural best management practices (BMPs) described
in this chapter.
d. All sites must be inspected regularly by a representative from the project to
document the condition and effectiveness of BMPs.
7. Retain Sediment - Sediment control measures are required at all points where
stormwater leaves the site as concentrated flow and at any other points where sediment
has the potential to leave the site. Sediment-laden runoff will be considered a
violation of City of Aspen code and can receive fines up to $1000 per day that the
site is in violation.
Best Management Practices
Best Management Practices (BMPs) are activities or controls that are implemented to reduce
the potential of discharging pollutants to the stormwater system and include pollution prevention
measures and EPSC measures.

2.1 Permit and Construction Process
Step 1 – Develop Construction SWMP
The owner or the contractor should secure the services of a professional engineer
knowledgeable in construction management practices and the City of Aspen requirements for
stormwater management during construction to develop the Construction SWMP. The SWMP
must be submitted as a portion of the CMP along with the building permit application. The
Construction SWMP will be reviewed by the City and its comments will need to be addressed
before a building permit will be issued.
Projects that disturb greater than one acre of land will also need to apply for a Construction
General Permit with the CDPHE. This application also requires the submittal of a SWMP. The
Construction SWMP developed for the purposes of construction within the City of Aspen should
be adequate to submit with the Construction General Permit Application.
The Construction SWMP shall consist of a written narrative report and a site plan map
describing the erosion prevention and sediment control measures to be implemented at the site.
Narrative Report
The narrative report must contain, or refer to, the drainage report for the site and should contain,
at the minimum, the following:
1. Contact Information – The names, addresses, email addresses and phone numbers of
the project/property owner, the applicant or permit holder, the professional engineer
preparing the Construction SWMP, and the site person that will be responsible for
implementation of the Construction SWMP.
2. Project Description - A brief description of the nature and purpose of the land disturbing
activity, the total area of the site, the area of disturbance involved, and project location
including township, range, section, and quarter-section, or the latitude and longitude, of
the approximate center of the project.
3. Existing Site Conditions - A description of the existing topography, vegetation, and
drainage; and a description of any water bodies or conveyances on the site.

construction activities and materials and the methods described in this chapter which will
be used to prevent pollution to the stormwater system. Descriptions
10. Timing of Construction Activity – A schedule indicating the anticipated starting and
completion time periods of the site grading and/or construction sequence, including the
installation and removal time periods of erosion and sediment control measures, and the
time of exposure of each area prior to the installation of temporary EPSC measures.
02/22/2019
11. EPSC Measures - A description of the methods described in this chapter which will be
used to prevent erosion and control sediment on the site. Descriptions must be site
specific. Generic or general statements are not acceptable.

measure will be maintained and a statement that the site will be inspected at least once
every 14 calendar days and 24 hours before / after forecasted storm events to determine
SWMP accuracy and effectiveness; proper installation, location, and condition of EPSC
measures; and implementation of construction activity pollution prevention measures. An
alternative of inspecting every 7 calendar days regardless of precipitation events or
forecasts may also be used. Inspection and maintenance reports should be completed
and kept on site following each inspection and made available to City of Aspen staff
upon request. Any loss of sediment from the site should be noted and kept in file with
these reports, including date and estimated amount of sediment loss and what activities
were performed to ensure that sediment loss would not occur again.
15. Calculations - Any calculations made for the design of such items as sediment basins,
diversions, or waterways; and calculations for runoff and stormwater detention basin
design (if applicable).

02/22/2019
Step 2 – Approval of Construction SWMP
The Construction SWMP must be approved prior to issuance of a Building Permit by the City.
The final SWMP must be consistent with a Drainage Report accepted by the City of Aspen
Engineering Department. However, approval of the SWMP does not imply acceptance or
approval of Drainage Plans, Utility Plans, Street or Road Plans, Design of Retaining Walls or
any other aspect of site development.
2.2.1 Exemptions and Variances
These are generally processed according to the applicable municipal regulations and reviewed
on a case-by-case basis.
1. Exemptions from the erosion control planning process may be considered for any of the
following by the local jurisdiction if their MS4 permit so allows; however, exempting the owner
from the preparation and submittal of a SWMP and/or from applying for a grading permit does
not exempt the owner from controlling erosion and sediment movement off the construction site:
a. Agricultural use of land.
b. Grading or an excavation below finished grade for basements, footings, retaining walls, or
other structures on single family lots not a part of a larger development or redevelopment
project and disturbing a total land surface of less than one (1) acre in size unless required
otherwise by local jurisdiction.
c. A sidewalk or driveway authorized by a valid permit.
d. Land-disturbing activities involving less than a total of one (1) acre of disturbed area.
Individual lots involving less than one (1) acre of disturbed area in a larger land use change
project shall not be considered separate development projects, but rather as a part of the
subdivision development as a whole and are not eligible for an exemption. It will be the
responsibility of the homeowner or homebuilder to conform to all requirements of the locally-
approved SWMP for the development or redevelopment. As part of any Building Permit within a
larger development for which an individual erosion control plan is not required, it is
recommended the following statement be included: "We have reviewed the Construction Storm
Water Management Plan for (subdivision name) and agree to conform to all requirements
contained therein and all erosion control requirements of the (insert name of municipality) and
the State of Colorado. We further agree to construct and maintain all erosion and sediment
control measures required on the individual lot(s) subject to this Building Permit and/or in
accordance with the provisions of the Construction Best Management Practices chapter of the
Manual published by the Urban Drainage and Flood Control District."
e. Underground utility construction including the installation, maintenance and repair of all
utilities under hard-surfaced roads, streets or sidewalks provided such land-disturbing activity is
confined to the area which is hard-surfaced and provided that runoff and erosion from soil
stockpiles are confined and will not enter the drainage system.
f. Gravel, sand, dirt or topsoil removal as authorized pursuant to approval of the Colorado Mined
Land Reclamation Board, provided said approval includes a construction activities
management, erosion and sediment control plan that meets the minimums specified.
g. Projects having a period of exposure (from time of land disturbance until permanent erosion
control measures are installed) of less than 14 days.
h. Where the owner certifies in writing to the City of Aspen and the City of Aspen agrees in
writing that the planned work and the final structures or topographical changes will not result in,
or contribute to, soil erosion or sediment discharges to any waterway or irrigation ditch and will
not interfere with any existing drainage course or waterway in such a manner as to cause
damage to any adjacent property, or result in the deposition of debris or sediment on any public
right-of-way, will not present any hazard to any persons or property, and will have no
detrimental influence upon the public welfare, or upon other properties in the watershed.
02/22/2019
2. Variances – The City of Aspen may consider waiving or modifying any of the criteria which
are deemed inappropriate or too restrictive for site conditions by granting a variance, provided
such variance does not violate the laws of the State of Colorado or the Federal government.
Variances may be granted at the time of plan submission or request for plan revision. Variances
must be requested in accordance with the subdivision regulations and must define:
a. The criteria from which the applicant seeks a variance.
b. The justification for not complying with the criteria.
c. Alternate criteria or standard measures to be used in lieu of these criteria. The criteria and
practices specified within this section of the Manual relate to the application of specific erosion
and sediment control practices. Other practices or modifications to specified practices may be
used if approved by the municipality prior to installation. Such practices must be thoroughly
described and detailed to the satisfaction of the local municipality reviewing and approving the
erosion control plan. To expedite the review and decisions on variance requests, it is suggested
that a variance request be included with, or submitted prior to, the initial SWMP submittal.
Step 3 – Project Construction – Installation, Maintenance, and Inspections
During the construction phase, the following sequence is recommended for the implementation
of the project and the SWMP:
1. During preparation of the Construction SWMP, the contractor designated a manager for the
implementation of the SWMP. This person will be responsible for implementing all permit
conditions and will communicate with City inspectors and inspectors from other agencies.
2. Install all BMPs shown on the SWMP that need to be installed in advance of proceeding with
construction, such as construction fencing and limits of disturbance, tree and other natural area
protections, construction exits, silt fences, inlet protection, etc.
3. Identify construction equipment and materials storage and maintenance areas and install
BMPs to prevent pollutant migration from them.
4. Notify the City that the site is ready for initial inspection.
5. Install any additional BMPs that are called for in the SWMP before grading begins.
a. Strip off and stockpile topsoil for reuse. Insure that soil stockpile is not located in a
drainage path, downhill of a significant drainage area, is protected from erosion and dust
migration, and that a sediment control measure is located downstream.
b. Mulch areas that will remain undisturbed for more than two weeks during the April
through September rainstorm season (e.g., stockpiles and overlot graded areas that will
remain dormant for extended period of time), or for more than a month during the
October through March period.
c. Insure that BMPs that need to be installed at different times during the project are
installed when called for in the SWMP or by the City’s inspector and are in full operation
before construction activities begin in areas served by them.
02/22/2019
d. Inspections by site Supervisor / Professional Engineer
e. Inspections by City will occur regularly to inspect for general compliance with the
approved plan.
f. Maintenance by the permit holder / and or property owner is required for all BMP’s
regardless of the stage of construction.
g. Maintenance time frame from City
h. Enforcement from City will occur at any time when a permit holder / and or property
owner is in violation of the SWWP. Enforcement will escalate from verbal notices of
corrective actions to stop work orders based on the number of violations or the severity
of any one single violation.
Step 4 – Project Completion – Stabilization, Re-vegetation, and CO
Re-vegetate the site as called for in the SWMP.
1. After all work has been completed in an area
a. including stabilization and re-vegetation,
b. clean out and restore any post construction BMPs that may have been used for
construction sediment controls.
After all work has been completed on site, prepare the site for a CO inspection by the City and
arrange for this inspection by calling (970)920-5448. Correct all deficiencies and call for follow-
up inspection.
The owner or contractor needs to arrange for inspection by the local jurisdiction when the
vegetation has reached acceptable level of coverage and maturity. This could take months. In
the meantime, the owner or contractor need to inspect the site on a regular basis to determine if
there are deficiencies or damage that need to be addressed. The owner is responsible for the
performance of all erosion and sedimentation control installations until such time the site’s re-
vegetation is deemed acceptable and a written notice is provided to the owner by the local
jurisdiction.
Once re-vegetation has been accepted, request release of any surety, letters of credit or other
financial guarantees the local jurisdiction may have required the permit holder provide at the
time the permit is issued. A closure of the construction activities permit from the State should
also be pursued at this time.

Construction Noise Suppression Plan
As the General Contractor for this construction project, I ___________________ 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
________________________________. 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.
_______________________________ _____________________________

On-site Contact Phone # ___________________
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.

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.

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.
Revised 01/09/2013 02/22/2019
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.
