SYNOPSIS 
The Port purchased the entire land currently occupied by Town & Country Mobile Home Parks
in 2006. This authorization allows for the continuation of the relocation of mobile home 
residents affected by aircraft noise. The current acquisition and relocation plan was approved as
part of the update to the Port of Seattle's (Port) 2002 Federal Aviation Regulations Part 150 
Noise and Land Use Study. The Federal Aviation Administration (FAA) provides 80% Airport
Improvement Program (AIP) grant funding. 
REQUEST 
Request authorization for the Chief Executive Officer to execute all documents necessary to
complete the relocation of the residents, demolition of remaining manufactured homes, by
contract or Port crews, and site restoration of Parcel Numbers 344500-0110, 344500-0141,
344500-0145, 344500-0155 commonly known as Town & Country Mobile Home Parks (Town
& Country) in the City of SeaTac, located within the 1998 70 Day Night Level (DNL) noise
contour, at an estimated cost of $2,600,000 including legal and administrative expenses. This
request will bring the total authorization for this Capital Improvement Program (CIP) to
$52,306,110.

BACKGROUND 
Residents in mobile home parks adjacent to the Seattle-Tacoma International Airport (Airport)
within the 70 DNL noise contour are significantly impacted by aircraft noise. Since it is not
cost-effective to noise-insulate mobile homes, as the Port has done with other residential
structures, the FAA Regulation Part 150 Study Update completed in 2002, recommended that the
Port acquire the seven mobile home parks located within the 1998 70 DNL noise contour  two
north of the Airport, in the City of Burien, and five to the south, in the City of SeaTac. The Port
has completed the acquisition of all the parks and is in the process of relocating the residents of
the final park, named Town & Country (See Exhibit A). 
PROJECT DESCRIPTION/SCOPE OF WORK 
The scope includes relocation of the remaining residents and demolition of remaining
manufactured housing units. Town & Country is a large-sized park, and approximately 14 of the
original 200 households still need to be relocated. 
PROJECT JUSTIFICATION 
Staff developed an overall aviation acquisition priority strategy, which was presented to the
Commission in January 2002. The strategy identified criteria for prioritizing the large number of
acquisitions so that funding and staffing resources could be directed in a logical manner
consistent with construction schedules, budgets, noise impacts and acquisition timelines. Town
& Country was the last mobile home park to be acquired. 
STRATEGIC RATIONALE 
This action is in support of the Airport strategy to Develop and Maintain a Supportive
Community by assisting those residents most significantly impacted by aircraft noise in
relocating, and by facilitating the conversion of the land to uses compatible with an airport
environment. 
FINANCIAL IMPLICATIONS 
This request for additional authorization is due to the result of increases in the cost of real estate 
transactions associated with relocating residents from mobile home parks and specifically the
remaining residents in the Town & Country. 
The mobile home market is unique in this current economic crisis. It represents a viable housing
option for families who have been foreclosed or otherwise have not been able to secure
traditional housing. In contrast to the general real estate market, mobile homes prices are rising
due to increased demand from low-income residents moving out of rental situations who are
trying to build credit or equity as well as from families forced to move out of single-family

homes due to loss of jobs, increased mortgage payments or foreclosure. At the same time, the
inventory of mobile homes has decreased as municipalities have rezoned or restricted mobile
home park development. In addition, another local municipality (King County) started a mobile
home park acquisition-relocation project in mid-2008. The result is reduced supply and
continued high demand. These market pressures have led to an increase in mobile home values
and a resulting increase in Port costs to relocate the remaining residents of Town & Country.
Another significant factor leading to increased costs is the high percentage of non-English
speaking tenants within Town & Country who are in a low-income immigrant demographic 
group. This last group of tenants requires significantly more time and effort to re-locate due to
the need to find larger homes to accommodate their higher number of family members, to
substantiate their rental and credit history, and to secure outside social services that they need to
obtain decent, safe and sanitary housing. Because of these factors, the CIP budget needs to be
increased to cover the remaining relocation, abatement and demolition costs.

Effect on business performance     The Port does not charge airlines for the portion of the capital
costs funded by grants and PFC's. The ADF funded portion of
the project costs will be recovered through rates and charges, so
net operating income (NOI) after depreciation will increase.
