We convened a Lease Framework Working Group to do a policy review of our current lease framework and identify and evaluate possible opportunities and alternatives to make improvements.

As stated in the LFWG charter, "The Working Group will conduct a policy review of the current lease framework as well as identify and evaluate possible opportunities and alternatives to improve the leasing framework alignment with the Airport's Strategic Plan goals. The review will include, but will not be limited to, policies related to pricing and lease terms, exclusive rights, arbitration rights and procedures, investment credits and/or amortization of tenant investments, and assignment and transfer rights. These issues will be discussed over a series of meetings and identify alternatives, if applicable and feasible, in the form of potential policy or code changes."

The group met 13 times between August 2015 and October 2016. The members considered a range of policy questions, developed key findings from presentations and group discussions, and reached consensus on a list of focused recommendations to improve future hangar and long-term leasing practice at BFI.

Recommendations address the following topics:

• Hangar waitlist
• Hangar commercial rental rate
• Monthly hangar pricing and appraisal process
• Hangar vacancies
• Long-term lease appraisal process
• Long-term lease appraisal re-evaluation cycles and rent adjustment
• Length of long-term leases
• Long-term lease investment requirements
• Long-term lease award

For details on the group's process and products, see the final report:

• Lease Framework Working Group Findings and Recommendations (November 2016)

Future updates and discussions related to these lease topics and the working group's recommendations will take place at meetings of the Airport Roundtable.

The airport's ARFF unit typically offers free Adult CPR classes to all airport tenants and their employees. A CPR card will be sent to each participant after successful completion of the training. However, due to the COVID-19 pandemic, CPR classes are suspended until further notice.
