We have appreciated the informal guidance and discussion around our methodology, survey and proposed plan for moving forward. At this time, I would like to provide more specic information from the results of our survey and our draft implementation plan, and would appreciate any comments you might provide. We are proposing a three- year plan to remove obstructions, clear and replant with lower-height species. As noted in the attached implementation plan, we are proposing to conduct the work rst on Port-owned property, then on other publicly owned property, and nally on privately-owned commercial and residential properties. This phased plan is to address the number of vegetative obstructions which have developed since the obstruction removal survey work was last conducted in the mid-2000's, to mitigate the impact of removing a high number of full-size trees, and to improve the urban forest and understory on these sites. Thank you for your time and attention to this matter, and I look forward to your comments.

Box 1209 Seattle WA, 981 l l-1209 Dear Mr. Lyttle, Thank you for your November 1, 2016 letter regarding your Flight Corridor Safety Program. The Port of Seattle (Port) has developed this program to insure the safety of the National Airspace system and the SeattleTacoma International Airport. The Flight Corridor Safety Program demonstrates that the Port is to attempting to take appropriate action to protect instrument and visual operations to the airport. This effort is consistent with the Port's federal grant assurance obligations, specifically grant assurances #19 Operation and Maintenance, and #20 Hazard Removal and Mitigation. As the Port clearly understands, the airport grant assurances, while obligatory, are in place to assist the airport in maintaining a safe environment for all users. In particular, grant assurance 19 requires the Port to operate the airport at all times in a safety and serviceable condition and grant assurance 20 requires the Port to take appropriate action to assure that terminal airspace will be adequately cleared and protected by removing existing airport hazards and by preventing the establishment or creation of future airport hazards. We support the Port of Seattle's proactive approach to remain in compliance with the federal grant obligations through the development of the Flight Corridor Safety Program.
