JUSTIFICATION
Resolution No. 3683 was adopted by the Commission on October 22, 2013. This resolution
included all recommendations from the Part 150 Study including sound insulation for
condominium complexes. The goal of this program is to meet the requirements of Resolution
No. 3683 to conduct an ongoing noise remedy program.
DETAILS
The Port will provide funding, staff, consultant and contractor oversight, and administration of
the program to provide design and Project/Construction Management for the sound insulation
for condominiums which will consist of new sound rated windows, doors and ventilation to
eligible condominiums within the Noise Remedy Program Boundary. The Airport Noise
Program’s office estimates that there are three complexes (240 units) eligible to participate.
The firm procured will provide project management and will have experience in FAA Noise
Remediation work. Final oversight will be provided by the Port. The pre-construction design
and testing of potential complexes will define the project and provide cost estimates prior to
major construction contracting.
In order for a condominium complex to be eligible, it must be located within the FAA approved
Noise Remedy Boundary and has to have been built prior to the establishment of local
jurisdictional building codes that were enacted to either meet or exceed the FAA standards for
noise reduction. These dates include December 3, 1986, for the City of Des Moines and
September 6, 1987, for all other areas of King County. In 2012 the FAA implemented a
requirement for all FAA-funded sound insulation projects for acoustical qualification based on a
pre- and post- noise audit. Each building must be tested to ensure the interior noise level is at
least 45 A-weighted decibels (dB) with a minimum reduction of 5 dB that can be achieved
through installing sound insulation. Some buildings may not qualify under this new
requirement.
The consultant hired under this contract will help define the requirements both with FAA
eligibility and homeowner participation including agreements with the Homeowner
Associations. In return for sound insulation, all homeowners are required to provide the Port
with an Avigation Easement which will be recorded on the parcel permanently with King
County. An Avigation Easement provides the Port with protections for free and unobstructed
passage of aircraft over the parcel and becomes the Port’s asset.
Since the project will be partially funded with FAA AIP grants, the Port will be following the
United States Department of Transportation’s Disadvantaged Business Enterprise (DBE)
program requirements. Certified DBE goals will be administered in accordance to CFR 49 Part
26.
