21 IT Security Master Plan Master Plan 104.a. modernization or expansion of existing airports or the creation of a new airport 104.b. cost effectively satisfy aviation demand If you have or are considering Shared Tenant Services or Shared/Common Use, 202.b.4,6,7. Assess the ability of the existing airport, both airside and landside, to support the forecast demand. Identify the demand levels that will trigger the need for facility additions or improvements and estimate the extent of new facilities that may be required to meet that demand Identify options to meet projected facility requirements and alternative configurations for each major component.

22 IT Security Master Plan Master Plan 202.b.9. Facilities Implementation Plan Provides a summary description of the recommended improvements and associated costs. The schedule of improvements depends, in large part, on the levels of demand that trigger the need for expansion of existing facilities. This is an opportunity to discuss items that are related to IT such as Parking Management Systems, terminal/airfield lighting controls, life safety, etc. Don t forget your MDF/Comm. Rooms!
