contracts for replanting of replacement trees; (3) pay fees to the Washington State
Department of Transportation and local jurisdictions for them to perform replanting for
certain obstructions removed from their properties; (4) execute agreements with public
agency and private property owners as needed for purposes of obstruction
management; and (5) acquire those property rights reasonably necessary for
obstruction management and preventing future creation or establishment of airport
hazards. The total cost estimate for this request is $5,895,000 for a total estimated
project cost of $8,500,000.
Request document(s) included an agenda memorandum and presentation slides.
Presenter(s): Marco Milanese, Aviation Community Relations Manager; Steve Rybolt, Senior
Environmental Program Manager; and Chris Coulter, Capital Project Manager.
The background of the program, aimed at removing potentially hazardous obstructions – mostly trees
– from the airport’s flight corridor was described. Reevaluation of the Federal Aviation
Administration’s requirements for designating flight corridor obstructions in 2019 resulted in a new
analysis that significantly reduced the number of trees to be removed. This phase of the program is
focused on trees growing on non-airport properties. It includes execution of agreements with other
public agencies and private property owners. Tree removal is balanced by replanting on a ratio of
four new trees for each removed. It is unclear at this time whether the Washington State Department
of Transportation will replant at this exact ratio, as they have their own policies related to tree removal
and replanting. Every effort will be made to keep the impact to the airport’s neighbors to a minimum.
Various property rights, including permanent easements, will be used to preserve the airport’s safety
interest in keeping the flight corridor free of obstructions.
The motion for approval of agenda item 8a carried by the following vote:
In favor: Felleman, Gregoire, Steinbrueck (3)
Absent for the vote: Bowman, Calkins
8b. Authorization for the Executive Director to (1) execute a construction contract with the
low responsive and responsible bidder for the Baggage Optimization Phase 2 Project at
Seattle-Tacoma International Airport, notwithstanding the low bid exceeding the
estimate at time of bid by more than 10 percent, and (2) authorize an additional
$190,737,800 for Phase 2 construction and Phase 3 design for a total program
authorization of $540,050,000. (CIP #C800612).

Leader; and Chris Sherwood, Construction Manager.
The circumstances surrounding the bids exceeding engineer’s estimate were described. These
included complex sequencing of work, limited work window, and lack of optimal laydown space. The
costs associated with contractor risk of not completing on time included physical movement of
luggage in support of operations at the new International Arrivals Facility. Lessons learned from this
