COMMISSION AGENDA             Item No.          6e 
Date of Meeting       April 21, 2009 
DATE:    April 15, 2009 
TO:      Tay Yoshitani, Chief Executive Officer 
FROM:    James R. Schone, Director, Aviation Business Development and Management 
Robert F. Riley, Director, Aviation Capital Improvement Program 
W. Allan Royal, Manager, Port Real Estate Development 
SUBJECT: Remove debris and foundations of a building that burned down and clean up the
site. 
ACTION REQUESTED 
Request authorization for the Chief Executive Officer to complete demolition of the burned
building including foundation and debris removal, ancillary cleanup, grading, and restoration of
the site by use of Port Construction Services and/or authorize the CEO to advertise and execute a
construction contract to complete the work. Estimated value of this request, including soft costs
and a contingency for unknown conditions is $404,000. Construction for this request is
$228,000 (includes costs for PCS and/or construction contractor).
SYNOPSIS 
A portion of the former Angle Lake School burned, which left the site in a dangerous condition.
Asbestos and other regulated materials are in the process of being removed. Once that work is
complete, it is necessary to complete demolition and re-grade the site in order to return it to a
safe condition.
BACKGROUND 
The Port of Seattle purchased the Angle Lake School site in 2003, located at 19215 28th Avenue 
South in the City of SeaTac (see Exhibit A), in anticipation of future airport needs. The
buildings were boarded up. The main building was destroyed by an arson incident that left
regulated materials, including asbestos, exposed to the elements. Clean up of the regulated
materials commenced in March 2009 and is expected to be complete in 44 days. The Port, the
Washington State Department of Labor and Industries, and the Puget Sound Clean Air Authority
have been working cooperatively on this project. 
Port staff has completed the design and engineering estimates to remove the foundation and 
restore the site. This request will allow for demolition of foundation and site restoration.

PROJECT DESCRIPTION/SCOPE OF WORK 
Project Statement 
Demolish the foundation of the burned building including grading, clean up and restoration of
the building site at the Angle Lake School for a cost not to exceed $404,000. 
Project Objectives 
Finish the foundation demolition and site restoration including filling the hole and hydroseeding.
Scope of Work 
Demolish foundation and restore the Angle Lake School site. 
STRATEGIC OBJECTIVES 
This project supports the Port's strategy to "exhibit environmental stewardship through our
actions". 
ALTERNATIVES CONSIDERED/RECOMMENDED ACTION 
Take no action. Under this alternative the Port would not demolish the foundation which would
leave an exposed foundation and hole on the site with potential liability related to an open pit.
This is not a recommended alternative.
Proceed with the demolition of the foundation and site restoration: This will allow the
demolition of the foundation and the site restoration. The Port is investigating whether PCS has
available crews and time to complete this work or whether it would be better to advertise this
project and complete the work through a construction contract. Once the Port has determined the
appropriate way to proceed, the Port will either have the work performed by Port staff or
advertise and execute a construction contract.  This is the recommended alternative.

Project Cost Breakdown 
Current Request       Total Project 
Construction Costs                   $ 228,000         $ 627,000 
Sales Tax                         $ 19,000         $ 52,000 
Outside Professional Services             $ 0         $ 34,000 
Other                             $ 157,000         $ 238,000 
Total                              $ 404,000         $ 951,000 

The total estimated project cost at the start of design was $951,000. This included asbestos
abatement in Buildings #2 and #3; however, abatement of Buildings #2 and #3 will not be
completed at this time. Building #1 will abated and removed. The site will be graded and
restored where Building #1 was removed. The following items reflect changes since the original
concepts for the project were developed: 
The bids for abatement came in slightly lower; however, they are based on unit rates.
The final number may vary. We must carry a contingency; 
We have to carry a contingency for unforeseen items such as underground tanks or
contaminated soils;
As a result, abatement for the remaining buildings has been put on hold. We will assess
the project budget after completion of demolition and site restoration to determine if there
are funds available to abate the remaining buildings. We will make a recommendation to
the Port Commission on how to proceed.

Source of Funds 
The project costs will be accounted for as expense. As such, the funding source is the Airport
Development Fund. Some costs were recognized in 2008 as an environmental reserve; the
remaining costs are included in the 2009 operating budget.
ECONOMIC IMPACTS 
This project will fulfill the Port's commitment to public safety, to support improving the
environment and to support local jobs. The restored site will remove a large burden to future
potential development on the site.
