TO:      Tay Yoshitani, Chief Executive Officer 
FROM:    Stan Shepherd, Manager, Airport Noise Programs 
SUBJECT:  Sound Mitigation of Highline Community College Building 4 (CIP #C200042)
Amount of this Request: $1,939,689        Source of Funds: 
Airport Improvement Federal Grants  80% 
Passenger Facility Charges  15% 
Airport Development Fund  5% 
Estimated State and Local Taxes Paid: $126,970 
Total Estimated Project Cost:     $10,822,000     No. of Jobs Created: ? 

ACTION REQUESTED: 
Request Commission authorization for the Chief Executive Officer to execute all documents
necessary to complete the sound mitigation work on Building 4 at the Highline Community
College (HCC) at an estimated project cost of $2,154,266, including administrative expenses.
This authorization request is for $1,939,689 and will bring the total authorization for various
sound mitigation projects at HCC to $8,194,619.
SYNOPSIS: 
This request for authorization will complete the Airport's obligation to acoustically insulate HCC
Building 4 which is the 14th building (of 22 total) the Airport has helped insulate against aircraft
noise as a result of cooperative agreements dating back to 1994. This authorization of
$1,939,689 will be added to the remaining available prior authorization of $2,114,577 to satisfy
the Airport's total obligation of $2,154,266 for Building 4. The Federal Aviation Administration
(FAA) Airport Improvement Program (AIP) reimburses 80% of eligible costs to the Airport.
The State of Washington pays other costs beyond acoustic noise insulation to complete the
renovation of the building. There is no Port property tax levy funding associated with this
request.

BACKGROUND: 
In April, 1994, the Port of Seattle (Port) and HCC entered into an agreement to provide Port
funding to the college to sound insulate a maximum of 22 classroom buildings against aircraft
noise. HCC hires and manages the contractors, and the Port reimburses the college for the
approved insulation-related work. Port insulation funds were understood to be dependent on the
State of Washington providing funding for the college's capital program. The complete set of
insulation projects was budgeted at $10,822,000 based on a very preliminary estimate before
appreciable final design or investigation work was completed. The details of each building were
unknown, as was the schedule. In general, the rate of remodeling has been slow, with HCC often
remodeling only one building each summer. Thirteen buildings have currently been sound
insulated. The remaining classroom buildings will be evaluated to determine need, funding
availability, and eligibility based on noise audits.
Originally, staff sought Commission authorization for three to five buildings at a time. To better
plan, estimate, and manage this multi-year commitment, Port staff will now be seeking
Commission authorization for one building at a time, after the HCC architect's estimate is
available. Due to the competition among colleges for state funding, a schedule has not been set
for the remaining eligible buildings. We will return to the Commission in the future for
authorization when additional buildings are identified for acoustical installation remodel work.
Additional funding may be needed at that time. 
State funding has been slated for 2012 for HCC to help complete work on Building 4. In
addition, the Port has worked with the FAA to make this Airport Capital Improvement Program
(CIP) AIP noise grant eligible to account for 80% of eligible costs.  Based on estimates provided
by the acoustical architect, the entire cost for the renovation of Building 4 is estimated at
$2,496,257. The Port's portion of funding to noise mitigate the building is $2,154,266, which
includes administrative costs as well as a contingency for construction costs. Because there is
only $214,577 remaining in the current CIP authorization, we are requesting authorization for
$1,939,689 which is the rest of the Port's portion. After this authorization, approximately
$2,627,381 of unauthorized budget will remain in the overall CIP budget for future
authorizations to improve other buildings. It is anticipated that more budget will be necessary in
the future to insulate the eight remaining buildings.
PROJECT DESCRIPTION/SCOPE OF WORK: 
The scope includes renovation of all remaining eligible items in the renovation of Building 4.
Major elements include installing sound rated windows, acoustical roof treatments, and
mechanical ventilation systems. The Port and FAA will be funding only acoustical-related items
in the reconstruction. HCC and the state will fund all non-acoustical related items. All work
should be completed in the years 2012 and 2013.

PROJECT JUSTIFICATION: 
In support of the airport strategy to Develop and Maintain a Supportive Community, the
Community Development Department works closely with local and regional leaders and
residents to develop and implement mutually beneficial land use compatibility agreements,
sound insulation programs, and property acquisition for noise. Completion of these programs
will reduce noise impacts on Airport neighbors while increasing land use compatibility around
the airport. 
FINANCIAL IMPLICATIONS: 
This request provides FAA AIP grant funds and Airport funds for mitigation of aircraft noise in
Building 4 at HCC. The budget authorization is based upon the estimate prepared by the
acoustical architect hired by HCC and an upfront allocation of eligible costs agreed to by the
Port. The Port reimburses HCC after the appropriate documentation is presented, reviewed, and
approved by the Port.
