Notes
A Part 150 Noise and Land Use Compatibility Study is required by the Federal Aviation
Administration (FAA) to update airport noise compatibility programs and provide eligibility for
grant funds. Sea-Tac’s last Part 150 update was completed and approved by the FAA in 2002.
Since that time, there have been significant changes in the airport’s noise environment. These
changes include building and commissioning the new third runway, the greater use of quieter
aircraft, and fewer operations than initially projected. In addition, the Port committed in both the
third runway Record of Decision (ROD) and the last Part 150 to doing an update to the Part 150
approximately one year after the third runway became operational.
This request is to procure a consultant to help design, implement and guide the next Part 150
update. The consulting team typically consists of professionals in land use planning, public
relations, noise, and environmental issues. In order to lower consulting costs during the process,
we intend to maximize the utilization of current Port employees in the areas of land use planning,
GIS applications, community outreach, environmental evaluations, and noise.
The Major focus of the Part 150 Noise and Land Use Compatibility Study update will be to
analyze changes in the noise environment with the recent inclusion of the new third runway, as
required by the EIS for the third runway’s master plan update. Other areas of focus will include
analysis of sideline noise, hush house feasibility, and noise abatement flight procedures for
operations on the third runway.
This project will be included in the Noise Programs Office expense budget for the years 2009,
2010, and 2011. The funding plan for this project will be 80% Airport Improvement Program
(AIP) grant funds from the FAA with the remaining 20% being funded by Airport Development
Funds (ADF). The estimated cost is between $500,000 and $1 million.
