Needs Assessment: The Update began with the Needs Assessment phase. An Inventory of Existing Conditions (airfield, terminals, roadways, parking, facilities, and more) and Aviation Activity Forecasts is being conducted. The Federal Aviation Administration (FAA) reviewed the forecasts. Upon FAA approval of the forecasts, facility requirements are assessed, to inform on potential gaps and areas for improvements. A Technical Advisory Committee (TAC) is convened to review the needs assessment and forecasts and identify additional input needed for potential solutions. 

Evaluation of Potential Solutions: Improvement alternatives will be developed and evaluated by the STLAA and reviewed by the FAA and the Update’s TAC. A preferred option will be selected for each component (airfield, terminal, roads, parking, etc.). When combined the result will create a future Airport Development Plan.

Refinement of Plan: Once a preferred Airport Development Plan is selected, environmental and financial analyses will ensure the plan is implementable and affordable. This phase of the Update is tentatively planned for early 2022.

Document Assembly: Finally, the Update's findings will be documented in a final report, which will present the 20-year vision and identify short- and long-term improvements.  It is anticipated this will be completed by the Summer of 2022.

FAA Draft Submittal: The final report will be submitted to the FAA for their formal review and acceptance, culminating in an updated ALP Update/MP drawing set.
