Airport Layout Plan Update and Master Plan - Introduction

Overview and Timeline

The St. Louis Airport Authority (STLAA) and the City of St. Louis are continuing the process of updating their current Airport Layout Plan Update and Master Plan (ALP Update/MP) for St. Louis Lambert International Airport (STL).  “The ALP Update/MP is a portrait of our airport’s potential,” says STL Airport Director Rhonda Hamm-Niebruegge. “The results of this ALP Update/MP will allow STL to make informed decisions on potential development and be in the best possible position to address the future needs of our passengers.”

What is an ALP Update/MP? An ALP Update/MP serves as a critical planning tool that looks at forecast aviation activity for an airport. At STL, the study uses this forecast as a guide in reviewing existing and future terminal, airside and landside improvements. 

The ALP Update/MP process has involved technical analyses, cost estimating, environmental considerations, developing existing 2020 and future 2040 noise contours based on a future fleet mix, discussion with airport stakeholders, public feedback through surveys and consideration towards industry standards and future conditions.

Stakeholder Engagement

The STL ALP Update/MP’s focus is on developing the terminal, roadway and airfield activities to accommodate future passenger and air traffic in 2040, the planning horizon for the study. Throughout the study, there have been meetings with airlines, the Technical Advisory Committee (TAC) and the Missouri Department of Transportation to garner input and comments to produce a recommended concept for terminal, landside and airfield recommendations. Additionally, surveys were distributed to the public for feedback on the terminal and landside concepts.  

ALP Timeline

The ALP Update/MP was started in January 2020 and is scheduled for completion in Summer 2022.  As shown in the timeline below, the study effort is now to refine the airside, terminal and landside alternatives to make recommendations as to how the Airport should address existing conditions as well as future development.  The next step will be assembling the document and submitting it to FAA for approval.
