TO:      Tay Yoshitani, Chief Executive Officer 
FROM:   Elizabeth Leavitt, Director, Planning and Environmental 
Wayne Grotheer, Director, Aviation Project Management 
SUBJECT:  Remediation of Lora Lake Apartments Site 
Amount of This Request:  $0        Source of Funds: Airport Development Fund 
Est. State and Local Taxes: $0         Est. Jobs Created: TBD 
Est. Total Project Cost:    $12,355,000 
ACTION REQUESTED: 
Request Port Commission authorization for the Chief Executive Officer to: (1) execute an
amendment to Model Toxics Control Act (MTCA) Agreed Order No. DE 6703 (2009 Agreed
Order), for additional environmental investigation and remediation planning for the Lora Lake
Apartments Site; (2) design and prepare construction documents for environmental remediation
at the Lora Lake Apartment Site; and (3) amend the Professional Services Agreement (PSA) P-
00316195 with Floyd/Snyder for environmental remediation of the Lora Lake Apartments Site
by $1.9 million from $2,505,775 to $4,405,775 and provide notification to the Port of Seattle
Commission, in accordance with RCW 53.19.060, that the amended amount exceeds 50% of the
original contract amount. Funding for this work was included in the 2013-2017 Environmental
Remediation Liability Program. 
SYNOPSIS: 
The Lora Lake Apartments site has dioxin contamination in the soil as a result of earlier
industrial operations, which must be remediated for the Port to be in compliance with state law
and for future reuse of the site. The Port acquired the property as part of the Third Runway
project due to its location. The presence of dioxin was not known at the time of the property
acquisition but was identified from subsequent testing. Port staff have determined that the cost
for remediation cannot be recouped from the previous operators and owners of the site. 
In order to proceed with the cleanup of the site, the Port must sign an amendment to the 2009
Agreed Order for additional site investigation and remediation planning as prepared by the
Department of Ecology (Ecology). Authorization for the design and preparation of construction 
documents along with an amendment to the PSA with Floyd/Snyder for environmental support
will allow remediation of the site to occur in 2014.

The redevelopment strategy prepared by the Port and the City of Burien has identified the Lora
Lake Apartment Parcel as appropriate for large-scale commercial or industrial uses such as auto
dealerships or air cargo logistics. 
BACKGROUND: 
The proposed Agreed Order Amendment and PSA amendment support remediation of the Lora
Lake Apartments Parcel in 2014, advancing by one year the schedule for potential
redevelopment and productive reuse of the property, as described below. 
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 the
construction of the apartment complex in 1986-87, the developer conducted environmental
investigations and remediation that were approved by Ecology under standards in place at that
time. 
The Port purchased the Lora Lake Apartments Parcel property in 1998 in support of the
development of the Seattle-Tacoma International Airport (Sea-Tac) Third Runway. In July 2007
the Port conducted environmental sampling in the portion of the property not required for Third
Runway support to obtain information about site conditions for future property redevelopment.
Sample data indicated significant contamination remained at the site. Further preliminary
investigations confirmed those findings and defined the general character of the contamination.
The Port negotiated with Ecology to complete the necessary remaining detailed site
investigations and evaluation of cleanup options under Ecology supervision pursuant to an 
MTCA Agreed Order. The Commission authorized Port execution of the 2009 Agreed Order on
June 9, 2009.
The primary focus of the 2009 Agreed Order was investigation of conditions and evaluation of
remedial options for the property that had been the site of the Lora Lake Apartments. To address
public concerns, Ecology directed the Port to also investigate conditions at other properties in
which contaminants originating at the Apartments property might have "come to be located." As
a result, the Lora Lake Apartments "Site" was expanded to include three parcels: the Lora Lake
Apartments Parcel (consists of the former Apartments property), the Lora Lake Parcel (includes
Lora Lake and surrounding uplands), and an area historically used for disposal of sediments
dredged from Lora Lake, the Dredge Material Containment Area (DMCA). 
The remedial investigation of all three parcels has been completed. The feasibility study of
remedial options for the Lora Lake Apartments Parcel and the DMCA has been completed.
Ecology has indicated its preferred remedial actions for those parcels, which decision is subject
to future public comment. The feasibility study for the Lora Lake Parcel will be completed by
the end of 2012, and Ecology will select a remedy, completing an overall Site Cleanup Action
Plan. The public will be given an opportunity to review and comment on a site-wide Remedial
Investigation/Feasibility Study (RI/FS) report and proposed Cleanup Action Plan. Ecology will
make any changes in the Cleanup Action Plan warranted by received public comment. Assuming
that the Port Commission authorizes doing so, the Port would then enter into another Agreed
Order (or alternatively, a Consent Decree) to implement the Cleanup Action Plan (the "Cleanup

Order"). Based on current schedule projections, entry of the Cleanup Order would occur in the
second or third quarter of 2013, resulting in Lora Lake Apartments Parcel remediation in 2015. 
The proposed amendment to the 2009 Agreed Order would enable Ecology to review and
approve, subject to future public comment, the Port's detailed draft Cleanup Action Plan prior to
entry of the Cleanup Order. This early start to the design period would enable remediation of the
Lora Lake Apartments Parcel in 2014 rather than 2015, as desired by, and to the benefit of all
stakeholders (the City of Burien, Ecology, the community and the Port). 
The Lora Lake Apartment Parcel is located within the City of Burien's Northeast Redevelopment
Area (NERA). The City identified NERA as an area affected by present and future aviation
activities. The City and Port have partnered to prepare a redevelopment strategy for the
NERA. The redevelopment strategy identified the Lora Lake Apartment Parcel as appropriate
for large-scale commercial or industrial uses such as auto dealerships or air cargo logistics. 
Associated with today's request for authorization to execute the 2009 Agreed Order amendment
is a request to add $1,900,000 to the Port's PSA with the Port's environmental consultant. In
May of 2009, the Port issued a competitive procurement for a project specific Category III PSA 
to retain a qualified environmental consulting firm to provide all services necessary to design and
implement a contaminated soil and ground water investigation and remediation of the Lora Lake
Apartments Site. The request for proposal stated that the estimated cost for the on-site
investigation work was $600,000. In addition, it stated that, "additional phases of investigation,
and remediation of the site  are included in the Scope of Work, but the value of those scope
items and duration of Work cannot be estimated at this time." Floyd/Snider was selected to
perform the work. The original value of the executed contract was $1,555,315, which included
work that arose during negotiations for the 2009 Agreed Order that were not a part of the
$600,000 estimate. In December 2010, the contract was amended to adjust the scope of work
and associated budget consistent with Ecology's expansion of the site boundaries. This $949,460 
amendment brought the total contract value to $2,504,775. The contract has been amended six
additional times to add subcontractors and adjust billing rates; these six amendments did not
increase the total contract dollar value. 
The estimated value of the proposed contract amendment is $1,900,000. The estimated cost of
the originally scoped investigation was $1,555,315. The value of the expanded work
requirement and associated professional services agreement is greater than 50%. Staff today
requests that the Commission authorize execution of an amendment to the Floyd/Snider contract 
for $1,900,000 to complete the planning, design support and, if subsequently authorized by the
Commission, implementation of the Lora Lake Apartment Site remediation. 
PROJECT JUSTIFICATION: 
The overall goal of the investigation and Site cleanup is to significantly reduce or eliminate the
exposure of ecological and human receptors to soil contamination and thereby reduce or
eliminate adverse effects on resources in the project site. Cleanup of the property will allow for
its beneficial reuse.

Project Objectives: 
Perform the remediation work at the Site in accordance with the 2009 Agreed Order, and
any future Orders or Decrees that the Commission authorizes. 
Manage and perform the work, with project controls and contract systems in place. 
Identify and consider community values and concerns, as part of a formal Public
Participation Plan. 
PROJECT SCOPE OF WORK AND SCHEDULE: 
Scope of Work: 
Perform design and design support at the Site. Early phases of the design effort will be carried
out in a manner that considers the potential needs of future development on the Lora Lake
Apartment Parcel. Prior to completing the final design, staff will brief the Commission on the
status of future development. If applicable, staff will notify the Commission of project cost
increases above those needed for environmental cleanup alone and will request Commission
authorization to finalize the design in a manner that accommodates future development.

FINANCIAL IMPLICATIONS: 
There is no funding request as part of this authorization since the budget for this requested action
will be authorized in the annual environmental remediation liability program authorization
request (also scheduled for December 4, 2012). All costs will be accounted for as environmental
remediation liabilities 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 Parcel 
remediation program was included within the Commission's 2012 environmentalremediation
liability program  spending authorization, approved on December 6, 2011.   Additional
environmental remediation liabilities will be established in compliance with Port Policy AC-9, in
December 2012. The updated liability amount will be accounted for as a non-operating
environmental remediation liability expense since the clean-up costs are in preparation of the
expected sale of the property.
The costs are eligible for state grant funding if and when it is available.
As the project moves forward, the status will be reported annually to the Commission via routine
environmental liability reports and spending authorization requests. The source of funds will

continue to be the Airport Development Fund. The anticipated proceeds from the sale of the
property are estimated to be approximately $8.5 million. This will partially reimburse the Port
for the environmental costs incurred. 
STRATEGIC OBJECTIVES: 
This project will achieve the strategic objective of accomplishing cleanup of the Port's property,
with the intent of returning it to productive use. 
ENVIRONMENTAL SUSTAINABILITY: 
Under MTCA, Ecology reviews cleanup projects to ensure that they meet the substantive
requirements of federal and state laws and regulations that are applicable or relevant and
appropriate. 
Project planning and design efforts are considering and incorporating opportunities for materials
reuse, recycling, and/or reduction. Finally, if authorized in the future, implementation of the
cleanup remedy will include significant environmental controls and performance monitoring to
ensure public health and safety. 
BUSINESS PLAN OBJECTIVES: 
Remediation of the Lora Lake Apartments Site will reduce to acceptable levels threats to the
environment caused by historical property uses and operations, achieving compliance with
regulatory mandates, management of Port liabilities, and support of the local community, all in
alignment with the goals and objectives of the Aviation Division Business Plan. Returning the
property to productive use benefits both the Airport and the local community. Completion of the
Site remediation, moreover, is directly responsive to the Port's commitment to cooperative Port  
City of Burien property redevelopment.
TRIPLE BOTTOM LINE SUMMARY: 
State and federal laws require elimination of unacceptable levels of environmental risk caused by
the presence of contaminants in soil, groundwater, and sediment. From the perspective of the
surrounding communities and the customers that we serve, the Port's participation in site
remediation is the hallmark of responsible environmental stewardship. Cleanup also returns
contaminated land to a more productive state. 
ALTERNATIVES CONSIDERED AND THEIR IMPLICATIONS: 
The following alternatives were considered for accomplishing the work described in the Scope of
Work: 
Alternative 1: Do not authorize execution of the proposed amendment to the 2009 Agreed Order.
This alternative would delay remediation of the Site by at least one year, to the detriment of the
City of Burien and the Port, and could appear to be a rejection of expressed community concern.
This alternative could also result in the issuance of a unilateral Ecology enforcement order to
perform the work, which would eliminate Port control over the remediation activity and could
result in significant cost. This is not the recommended alternative.

Alternative 2: Authorize execution of the proposed amendment to the 2009 Agreed Order, but do
not authorize amendment of the existing Floyd/Snider PSA. Conduct the remainder of the Lora 
Lake Apartment Site remediation effort using Port resources, without outside consultant
assistance. There are insufficient Port staff resources and specialized expertise to efficiently
deliver the effort to remediate the site without consultant support. This is not the recommended
alternative. 
Alternative 3: Authorize execution of the proposed amendment to the 2009 Agreed Order, but
conduct a separate procurement for the next phases of the work, potentially retaining a different
environmental consultant to perform the remediation tasks and to provide design support to Port
staff. The existing PSA specifically includes the subject scope of work and the current
environmental consultant has the needed specialized expertise. The time needed to re-procure a
consultant with similar expertise would delay the remediation by at least one year and result in
additional cost. This is not the recommended alternative. 
Alternative 4: Authorize execution of the proposed amendment to the 2009 Agreed Order and
amendment of the existing Floyd/Snider PSA, consistent with its Scope of Work, to provide
design support to Port staff. This alternative would result in compliance with the 2009 Agreed
Order issued by Ecology and, if subsequently authorized by the Commission remediation of the
site occurring in 2014. This is the most expeditious and cost effective approach. This is the
recommended alternative.
