PORT OF SEATTLE 
MEMORANDUM 

COMMISSION AGENDA                 Item No.     6a 
Date of Meeting    May 5, 2009 
DATE:    April 9, 2009 
TO:      Tay Yoshitani, Chief Executive Officer 
FROM:    Elizabeth Leavitt, Director, Aviation Environmental Programs 
Paul Agid, Environmental Program Supervisor, Aviation Environmental Programs 
SUBJECT:  Authorization to contract for environmental investigation, remediation, and associated
regulatory coordination activities for the Lora Lake Apartments property. 
ACTION REQUESTED 
Request for Port of Seattle (Port) Commission authorization for the Chief Executive Officer to 
procure and execute a contract for consultant services for environmental investigation and
remediation of the Lora Lake Apartments property. The estimated cost for the Remedial 
Investigation / Feasibility Study phase of the Lora Lake Apartments remediation is $1,000,000.

SYNOPSIS 
Soil and ground water at the Lora Lake Apartments site was contaminated prior to the Port of Seattle 
gaining ownership. The contamination is the result of former industrial operations from the 1940s  
1980s. Remediation of the contamination is required by state law, and is necessary for future
redevelopment on the site. 
Preliminary investigations performed as part of the Third Runway project have defined the general
character of the contamination. The Port has used the results of these investigations as a basis for
protecting against mobilization of contaminants from the site. The Port is currently negotiating with
the Washington Department of Ecology (Ecology) to define the scope of more refined studies that
will form the basis for site remediation. The cleanup will be supervised by Ecology pursuant to an
Agreed Order. Staff will return to Commission within the next several months to obtain
authorization to enter into the negotiated Agreed Order. 
Authorization for the Lora Lake Apartments property environmental management activities were
previously approved by the Commission in its 2009 Port Environmental Reserve spending
authorization of December 15, 2008. No additional authorization of funds is being requested at this
time.

BACKGROUND 
The Lora Lake Apartments property was the site of a barrel cleaning facility in the 1940s  1950s,
and an auto wrecking yard in the 1960s  1980s. Both of these types of industrial uses are known to
have had high potential for releasing contaminants to the environment during those periods. During
the construction of the apartment complex in 1986-87, the developer conducted environmental
investigations and remediation that were approved by Ecology under laws in place at that time. 
The Port purchased the Lora Lake Apartments property in 1998 in support of the development of the
Seattle Tacoma International Airport (Sea-Tac) Third Runway. By 1999 all residents had vacated
the property in anticipation of Port redevelopment for airport and airport-compatible light
industrial/commercial use. Prior to demolition, the Port sold the property to the King County
Housing Authority (KCHA) for a limited period, for residential use. KCHA sold the property back
to the Port in July 2007, at which time the Port demolished a sufficient number of structures to
comply with FAA regulations for airport runway operation. 
At the same time, using an existing on-call consultant contract, the Port conducted environmental
sampling to obtain information about site conditions for future property redevelopment. Sample data
indicated significant contamination remained at the site. Further preliminary investigations
confirmed the earlier findings. 
The Port has entered negotiations with Ecology to complete the necessary remaining detailed site
investigations under Ecology supervision pursuant to a Model Toxics Control Act (MTCA) Agreed
Order. The Remedial Investigation / Feasibility Study (RI/FS) Agreed Order, when complete, will
incorporate a specific scope of work that will include, among other tasks: developing a public
participation plan; establishing site protections that minimize the risk of releasing hazardous
substances during structure demolition; conducting investigations to fully characterize the nature and
extent of on-site and associated off-site contamination; and evaluating appropriate site remediation
methods. Ecology is committed to completing the RI/FS Agreed Order on a schedule that supports
the Lora Lake Apartments structure demolition project previously authorized by the Commission. 
Ecology anticipates issuing a second Agreed Order for supervision of final remediation design and
implementation. 
To date, the Port has used an environmental consulting firm contracted via an on-call professional
services agreement. That contract will expire in late 2009. Staff is now requesting authorization to
conduct a project-specific procurement process to select and contract with an environmental
consultant to perform services required to complete remediation of the Lora Lake Apartments
property. Staff will return for further Commission approval in order to obtain authorization to sign
the RI/FS Agreed Order.

BUSINESS PLAN OBJECTIVES 
Procurement of a qualified environmental consulting firm/team is necessary for remediation of the
Loral Lake Apartments property. Remediation of the Lora Lake Apartments property will minimize
to acceptable levels threats to the environment caused by historical property uses and operations. 
Completion of site remediation is required for cooperative Port  City of Burien property
redevelopment. The product of these efforts, as well as the attendant compliance with regulatory
mandates, management of Port liabilities, and support of the local community, aligns with the goals
and objectives of the Aviation Division Business Plan. 
ALTERNATIVES CONSIDERED / RECOMMENDED ACTION 
The following alternatives were considered for accomplishing the work described in the Scope of
Work: 
Alternative 1 
Do not conduct further investigation and remediation of the Lora Lake Apartment property. This
alternative could result in the issuance of a unilateral Ecology enforcement order to perform the
work, which would eliminate Port control over investigation and remediation activity and cost. 
Alternative 2 
Conduct the investigation and remediation of the property using Port resources, without outside
consultant assistance. There are insufficient staff resources and expertise to conduct this remediation 
without consultant support. 
Alternative 3 
Conduct a competitive procedure to procure and contract with a qualified environmental consultant
to conduct Lora Lake Apartments property investigations as defined under the RI/FS Agreed Order
now being negotiated, and site remediation under the Remediation Agreed Order to follow. This
alternative will result in continuation and completion of remediation of contaminated Port property,
as required by state law. This is the recommended alternative. 
SCOPE OF WORK 
The scope of work that will be performed by the selected consultant will be defined by Agreed
Orders negotiated by the Port and Ecology. Although not finalized, we are reasonably certain of the
principal elements of the RI/FS Agreed Order scope of work that will be assigned to the selected
consultant:

Remedial Investigation / Feasibility Study (RI/FS) Phase of Work 
Prepare a Public Participation Plan and support the Port's public involvement efforts. 
Prepare a RI/FS Work Plan. 
Perform a Remedial Investigation as defined in the work plan. 
Perform a Feasibility Study to determine the method of site remediation. 
Remediation Phase of Work (to be completed under the Remediation Agreed Order) 
Prepare a Site Cleanup Action Plan, and support the Port's implementation of that plan,
including but not limited to preparation of construction plans and specifications. 
Prepare documentation of site investigation and remediation activities sufficient to achieve
site conditions and regulatory status that enable property redevelopment. 
Associated regulatory coordination and negotiation activities. 
FINANCIAL IMPLICATIONS 
Cost Estimate 
Although not part of this Commission authorization, the estimated total project expenditure is
$1,000,000 for the RI/FS phase of work. Actual costs may exceed this estimate due to investigation
results. Insufficient information is available at this time to estimate the cost of the Remediation
Phase of Work. 
Source of Funds 
All costs will be accounted for as environmental reserves and charged to expense in accordance with
Port Policy AC-9. As such, the Airport Development Fund will be the funding source. 
The Lora Lake Apartments property remediation program was included within the Commission's
2009 environmental reserve spending authorization, approved on December 15, 2008. Additional
environmental reserve funds may be established as more site-specific information is generated, in
compliance with Port Policy AC-9, and will be reported to the Commission via routine
environmental reserve reports and spending authorization requests. 

COMMUNITY/CUSTOMER/ORGANIZATION IMPACTS 
Elimination of unacceptable levels of environmental risk caused by the presence of contaminants in
soil and groundwater is not only required by state and federal law, it is the hallmark of responsible
environmental stewardship, from the perspectives of both the surrounding residential and business
communities and the customers we serve.

Authorization of a competitive selection process and contract execution with the selected
environmental consultant will provide the experience and expertise required to perform remediation
of the Lora Lake Apartments property in satisfaction of both regulatory and community interests. 
PROJECT SCHEDULE 
This authorization enables initiation of a Category 3 procurement process in the second quarter of
2009. 
Previous Commission Action 
This May 5, 2009  request for Commission authorization is the first request for Commission action
specifically focused on the Lora Lake Apartments property remediation. 
On December 15, 2008, the Port Commission approved 2009 expenditure of $10,396,000 from Port
Environmental Reserve funds, for environmental remediation of the various Port properties for
which funds have been reserved. The Lora Lake Apartments property was included in that
authorization request.
