SUBJECT: Sound Insulation for Places of Worship Construction Authorization (CIP #C200098)
Amount of this request:
$3,500,000
Total estimated program cost:
$25,872,000
ACTION REQUESTED
Request Commission authorization for the Executive Director to advertise, award and execute a
major public works contract, and fund construction for sound insulation on places of worship
program (CIP #C200098) in an amount not to exceed $3,500,000 of the total places of worship
program cost of $25,872,000.
EXECUTIVE SUMMARY
The Sound Insulation Program exists to help reduce community noise impacts caused by aircraft
utilizing the Airport. As part of its long-term commitment to communities surrounding the
Airport, the Port offers sound insulation for eligible properties within the current Federal Aviation
Administration (FAA) Airport Noise Compatibility (Part 150) noise remedy boundary. This includes
places of worship.
Construction work includes installation of new Sound Transmission Class (STC) rated windows,
doors, and storm doors, as well as supplemental ventilation to meet the FAA standard of 45
decibel (dB) Day-Night Average Sound Level (DNL) interior noise that can be achievable with at
least a 5 dB reduction. This request will allow the Port to commence construction for sound
insulation on the places of worship program. The Sound Insulation Program is on-track to
complete in accordance with Commission Motion 2020-04 requiring completion no later than
2026.
The Commission previously authorized design funds for five participating places of worship
properties. Currently, the program has three properties that are participating with design
underway and are included in this construction authorization. The project budget continues to

include funding for all five places of worship, and funding will be returned for properties that
continue not to participate.
The Port has received $6.25M in FAA Airport Improvement Program (AIP) grant funding to
partially fund places of worship design and construction.
This request does not include work associated with condominium buildings, single-family homes,
apartment complexes and south Approach Transition Zone (ATZ) voluntary residential
acquisition.
JUSTIFICATION
Resolution No. 3683 was adopted by the Commission on October 22, 2013, and included all
recommendations from the Part 150 Study, including sound insulation for eligible structures
within the Noise Remedy Boundary. This authorization will help to meet the requirements of
Resolution No. 3683 to conduct an ongoing Sound Insulation Program.
In February 2020, the Commission passed Motion 2020-04 to accelerate this work with the goal
of completing work on these programs by the end of 2026. Moving forward with the places of
worship sound insulation is critical to compliance with the Motion.
Diversity in Contracting
The places of worship program will be partially funded with FAA Airport Improvement Program
(AIP) grants and the Port will follow the United States Department of Transportation’s
Disadvantage Business Enterprise (DBE) program requirements. A DBE goal of 7% has been
established for places of worship construction and the DBE Plan will be administered in
accordance with 49 CFR Part 26 by the Diversity in Contracting Department.
DETAILS
This request is for construction authorization that includes 3 places of worship properties that
are eligible to participate in the program.
Under state law, (R.C.W. 53.54.030), any owner who participates in the program is required to
provide the Port with an Avigation Easement in return for the Port paying the cost of the
improvements. A Subordination Agreement or Consent is required to convey the Avigation
Easement if there is a mortgage, deed of trust, or other lien on the property.

ALTERNATIVES AND IMPLICATIONS CONSIDERED
Alternative 1 – Authorize Places of Worship Program Sound Insulation Program to commence
construction (CIP #C200098).
Cost Implications: $3,500,000 (CIP #C200098).
Pros:
(1) Meets commitment to noise remediation in the community per Commission Resolution
3683.
(2) Maintains the critical path program schedule to meet the intent of Commission Motion
2020-04 to accelerate the airport’s noise mitigation programs prior to 2026.
(3) Allows staff to begin construction of the places of worship program.
(4) Provides a direct community benefit to reduce aircraft noise impacts.
Cons:
(1) The Port assumes the financial risk for this work if FAA AIP grant funding cannot be
secured.
This is the recommended alternative.

Annual Budget Status and Source of Funds
This project, CIP C200098, was included in the 2023-2027 capital budget and plan of finance with
a budget of $25,872,000. The funding sources would be AIP grants, AIP reinvested fund and
revenue bonds.
The capital cost of the entire places of worship program is estimated at $25,872,000. The AIP
grants is estimated at $16 million. Therefore, the airlines Rate Base Cost is estimated at $9.8
million which would not require Majority in Interest project approval from the airlines. The debt
service of 25-year amortization would be charged as landing fee when each place of worship
property construction is substantially completed and grants are received.
