COMMISSION AGENDA               Item No.       6d 
ACTION ITEM             Date of Meeting    April 23, 2013 

DATE:    April 16, 2013 
TO:      Tay Yoshitani, Chief Executive Officer 
FROM:   Stan Shepherd, Manager, Airport Noise Programs 
SUBJECT:  Residential Sound Insulation Funding Authorization - CIP C200093 

Amount of This Request:  $8,800,000   Source of Funds: Airport Development Fund 
Est. State and Local Taxes: $450,000    Est. Jobs Created: 20 
Est. Total Project Cost:    $13,747,395 
ACTION REQUESTED: 
Request Commission authorization for the Chief Executive Officer to expand the scope of the
sound insulation program, increase funding by $8,800,000, and execute all documents, including
consulting contracts and Job Order Contracts (JOC) necessary to complete the sound insulation 
program for approximately 90 single family homes, located between the current noise remedy
boundary and the proposed smaller Part 150 boundary. The estimated cost of this request is
$8,800,000, to bring the total project budget up to $13,747,395. This request is for additional
funding and scope change within the existing CIP C200093. 

SYNOPSIS: 
Work is progressing on the Part 150 Noise and Land Use Compatibility Study update. Upon
conclusion of the update and subsequent approval by the Commission and the Federal Aviation
Administration (FAA), the proposed noise remedy boundary will be shown as smaller, due to a
decrease of the Day Night Level (DNL) noise contours. The Noise Programs Office identified
302 homes between the existing noise remedy boundary and the newly revised smaller boundary
that have not yet received sound insulation services. These homeowners were contacted by
certified mail in 2012, informing them of a deadline to submit an application for sound insulation
services, or advising them that they may no longer be eligible for the program once the proposed
noise remedy boundary goes into effect. Of the responses received, it was determined that 90
homes may be eligible to receive sound insulation services, based on their location within the
current noise remedy boundary and because the homes were built prior to local jurisdictions
enacting building codes that either met or exceeded the FAA's noise reduction standards. These
building codes were enacted on December 3, 1986, in Des Moines and September 6, 1987, in all
other areas of King County. Costs to sound insulate a home under the program average $98,000.

BACKGROUND: 
Services provided under the sound insulation program are made available at no cost to eligible
owners of single family residences. Homeowners who choose to participate in the program are
required to sign an "avigation easement" before services are received. An avigation easement is
required by state law and permanently recorded on King County parcel records, providing legal
protection to the Port related to ongoing noise impacts resulting from aircraft over flights. 
Commission Resolution No. 2943, approved January 8, 1985, authorized the Port to conduct an
ongoing noise insulation program to insulate homes and public buildings located in the identified
noise remedy boundary. The Commission authorized staff to implement the insulation program,
including periodic evaluation of the program and budgeting for future needs.
The Noise Mediation Agreement Resolution No. 3062, approved on May 8, 1990, authorized
continued program implementation, including acceleration and transition from a cost-sharing
agreement between the Port and the homeowner to a Port-funded insulation package.
Resolution No. 3212, approved August 1, 1996, committed the Port to fulfill additional noise
reduction measures associated with forecasted noise from new runway operations, in accordance
with Puget Sound Regional Council Resolution (A-96-02), associated with the approval of the
Third Runway. 
In 1985, Port staff identified approximately 10,000 residential homes within the Noise Remedy
boundary area that were eligible for sound insulation work. To date 9,431 single family homes
have been insulated within that boundary. 
On December 7, 2010, Port staff requested additional authorization within the CIP in the amount
of $2,462,751 because the existing CIP authorization would not cover the costs. Th e December
2010 request was to sound insulate up to 40 homes at an estimated total cost of $3,092,040. The
per home cost at that time was $77,301. Over the past several years, program costs related to
contractors, materials, internal project management and oversight have consistently increased
year over year. Port standards have also changed with this progra m to meet more stringent
contracting and regulated materials handling.  As a result of the combination of internal and
external increases, costs per home now average $98,000, depending on size and condition of the
structure. The current request for funding will cover the costs of approximately 90 homes, which
were not included in the 2010 CIP authorization. 

PROJECT JUSTIFICATION: 
In support of the Sea-Tac Airport's strategic goal to develop valued community partnerships, the
Community Partnerships Department works closely with local officials and residents to develop
and implement mutually beneficial land use compatibility development agreements, sound
insulation, property acquisition, and noise abatement programs. Implementation of this 
insulation program will reduce noise impacts on Airport neighbors while increasing land use
compatibility in the vicinity of the Airport.

COMMISSION AGENDA

Project Objectives: 
Provide sound insulation to remaining eligible single family homes between the newly
revised and current/soon-to-expire noise remedy boundary. 
Achieve noise reduction within homes by providing a variety of sound insulation
measures to reduce interior noise levels. 
Meet the requirements of Commission Resolution No. 2943 to continue an on-going
noise insulation program. 
PROJECT SCOPE OF WORK AND SCHEDULE: 
Scope of Work: 
The Port will provide funding, staff oversight, and administration of a program to provide sound
insulation to single-family residences at no cost to the homeowner. Each home will have an
individual design created to reduce infiltrating noise levels, resulting in an interior noise
environment of no more than 45 decibels (dB). Significant interior noise reduction is achieved
primarily through replacing existing doors and windows with sound rated units and making 
necessary modifications to heating and ventilation systems. 
The Project Management Group (PMG) and Port Construction Services (PCS) will administer
and oversee all contracts and construction work. A Job Order Contract (JOC) is currently in
place to manage the construction work. The Port currently intends to execute additional
consulting contract(s) and JOCs to complete this work. The Port may also utilize small works 
contracts to provide opportunities for small business. 
Once funding is established, staff will process applications for homeowner participation. Staff 
estimate that this work will take two to two and one-half years to complete. 
To date, 37 homes out of the anticipated 40 from the 2010 authorization have been completed.
The 90 additional homes in this authorization request were not identified in the 2010 request for
funding.

ENVIRONMENTAL SUSTAINABILITY: 
There are no negative environmental impacts anticipated as a result of this project. To reduce 
interior noise levels to 45 dB or less, interior noise levels in insulated homes will be diminished
by at least five decibels. Construction work will include carefully chosen materials with
demonstrated long life and durability in a residential application. Materials with pre- and postconsumer
recycled material will be evaluated whenever appropriate and available for this
project. 
BUSINESS PLAN OBJECTIVES: 
Implementing the program will reduce noise impacts on Airport neighbors while increasing land
use compatibility in the vicinity of the Airport. The construction work associated with this
project will also bolster local business activity via the purchase of materials as well as providing
job opportunities in the local community. 
This program supports the following Port strategies: 
Fosters active community involvement through the noise mitigation work in the
residential neighborhoods surrounding the Airport. 
Honors the Port value of responsible stewardship of community resources and the
environment by significantly reducing interior noise levels in single family homes that
qualify for the noise program.
Supports Sea-Tac Airport's Environmental Strategy of reducing noise impacts within the
community. 
TRIPLE BOTTOM LINE SUMMARY: 
Implementation of this project will reduce noise impacts on qualified Airport neighbors by 
providing sound mitigation programs while increasing land use compatibility in the vicinity of
the Airport. This supports the Port's commitment of being stewards of our environmental
responsibility and partnering with our surrounding communities. The project supports small
business participation opportunities, which supports the Century Agenda goals.
ALTERNATIVES CONSIDERED AND THEIR IMPLICATIONS: 
Alternative (1) Close out the program without completing the remaining eligible homes. This
strategy would provide a negative impact since the Port has committed to community leaders and
homeowners that there would be one last chance to participate in the program for homes that
meet the criteria described above. 
Alternative (2) Allow the program to continue with additional funding to ensure that eligible
homes receive mitigation before program closeout. This strategy provides the best possible
solution to ensure that the Port carries through with its community commitments for reducing

aircraft noise within the community through essential mitigation programs. This is the
preferred alternative.
