PORT OF SEATTLE 
MEMORANDUM 
COMMISSION AGENDA             Item No.      5c 
Date of Meeting      1/25/2010 

DATE:    January 18, 2011 
TO:      Tay Yoshitani, Chief Executive Officer 
FROM:    James R. Schone, Director, Aviation Business Development 
W. Allan Royal, Manager, Port Real Estate Development 
SUBJECT: Acquisition of King County Parcel 202304-9013 from Seattle City Light. 
Amount of This Request: $ 239,212   Source of Funds: Airport Development Fund 
State and Local Taxes Paid: $ N/A      Jobs Created: N/A 
Total Estimated Project Cost: $3,000,000 
ACTION REQUESTED: 
Request authorization for the Chief Executive Officer to execute all necessary documents to
acquire by purchase King County Parcel 202304-9013 (Property) owned by Seattle City Light
located at 15002 8th Avenue South, Burien, WA. (Exhibit A) for $178,212.00 with a total cost of
$239,212.00. 
SYNOPSIS: 
The acquisition of this Property will create a contiguous parcel of land on a site in the Northeast
Redevelopment Area (NERA) which is under active consideration by the Airport for future
development of Airport-related uses. The Property is located in the center of the Port-owned
property known as the "Lora Lake/Red Apple" site and is a decommissioned electrical power
substation owned by Seattle City Light. Failure to acquire this parcel would leave a "hole" in the
middle of the site and make future development less viable because of the difficulty of
developing non-contiguous property. Successful development of the site would create jobs,
provide additional tax revenue for Burien and enhance the potential for non-aeronautical
revenue.
The Port has assessed the environmental contamination on the site, and there is no evidence of
residual soil or ground water contamination originating from on-site sources, but dioxins and
furans were present in all soil samples. The likely source of the dioxin and furan contamination
is from a source or sources on the Lora Lake property. The Port has accepted future liability for

environmental clean-up of the property in exchange for a modest purchase prices adjustment of
$6,788. The Port is already obligated to clean up the Lora Lake site. Total cost of the acquisition
of this Property is $239,212. The sale of the Property also requires Seattle City Council approval. 
BACKGROUND: 
The Port acquired the Red Apple property in 2000 and the Lora Lake property in 1998 as part of
the mitigation for the construction of the third runway. These two parcels consist of 13.3 acres.
Port staff is working on developing the Lora Lake/Red Apple property for an airport compatible
use. The acquisition of the Sunnydale property will create a contiguous parcel for development.
The Property is a decommissioned electrical substation.
The sale of the property also requires City of Seattle Council approval. 
Fair Market Value, $185,000 determined by independent MAI appraisal, was reduced to
$178,212 in consideration of potential additional costs due to testing and disposal of a small
portion of the site described in the environmental section of this memo. 
PROJECT JUSTIFICATION: 
Project Objectives: 
Acquire Property to complete assemblage of Lora Lake/Red Apple site. 
PROJECT SCOPE OF WORK AND SCHEDULE: 
Scope of Work: 
Acquire the Property from Seattle City Light to achieve complete assemblage of the 
Lora Lake/Red Apple site. 
Schedule: 
Complete the acquisition by end of first quarter 2011.

ENVIRONMENT AND SUSTAINABILITY:
The Port"s environmental consultants conducted Phase 1 and Phase 2 Environmental Site
Assessments on the parcel. The assessments revealed no evidence of residual soil or ground
water contamination on the Property originating from on-site sources.
There had been a confirmed release of transformer oil in 2001, but Seattle City Light remediated
the contamination in 2003 to the satisfaction of the Department of Ecology. However, the level
of cleanup required by the Department of Ecology is less stringent than the requirements at
landfills. This precipitated the negotiation for a reduction in price to account for the potential
additional cost of disposing of the contaminated soil at a landfill. 
According to the Phase 2 environmental analysis, dioxins and furans were present in all soil
samples analyzed. Based upon the evaluation of dioxin and furan test results from the Property 
and the Lora Lake property, it is likely that the source of the dioxin and furan contamination on
the Property is from a source or sources on the Lora Lake property. Port staff has reviewed the
site conditions. Property contamination associated with the seller"s site use is minor, and was the
subject of the purchase transaction negotiations. The Port accepts future liability in exchange for
a modest purchase price adjustment. Property contamination associated with the contamination
on the adjacent Lora Lake Apartments site is more significant, and is a liability already
recognized by the Port in the context of its Lora Lake Apartments obligations. 
STRATEGIC OBJECTIVES: 
This project supports the Port"s strategy to Ensure Airport and Seaport Vitality by assisting
future commercial developments and non-aeronautical revenue. 
BUSINESS PLAN OBJECTIVES: 
This project supports the Aviation Division"s Non-Aeronautical Business Plan Strategy. The
request supports the envisioned development of the Northeast Redevelopment Area (NERA) and
enhances the potential for non-aeronautical revenue. 
TRIPLE BOTTOM LINE SUMMARY: 
The assemblage of this site increases the potential for additional non-aeronautical revenue that
will help ensure the vitality of airport operations. The region will benefit from the creation of
jobs and added tax revenue from future environmentally compatible commercial or industrial
development projects.

ALTERNATIVES CONSIDERED AND THEIR IMPLICATIONS: 
Take no action. This alternative would leave a "hole" in the middle of the Port property
being considered for development. This would make the development less viable because of
difficulty in developing non-contiguous property. This is not a recommended alternative. 
Proceed with the Acquisition. This will allow the Port to complete the assemblage of the
property envisioned for development. This is the recommended alternative.
