On-Airport Development

Planning Department

What Does the Future of STL Look Like?

How many more guests will we welcome? What types of facilities will be needed to accommodate the next generation of travelers?

To answer these questions, The Federal Aviation Administration (FAA) approved STL’s 2023 Master Plan, a proposed roadmap to guide long-term development at STL. The Master Plan identifies a collection of projects that would be required to accommodate up to 40 million annual passengers and more than 500,000 annual aircraft operations, the estimated maximum capacity of the existing airfield.

No runway expansion is proposed in the approved Master Plan.

Planning for the Future

Funding

No general City or local tax dollars will be required. The airport funds its own operation entirely with aviation-generated funds, and the same is true for our ongoing and future capital improvement projects.
Funding sources for a proposed single-terminal project would include, but not be limited to, airport revenue bonds, landing fees, parking fees, concession revenues, and rents.
Looking at other new terminal programs at medium hub sized airports (like Kansas City International, New Orleans International, and William P. Hobby in Houston), the cost range at these facilities is $40-45M per gate and our plan includes up to 62 gates and is in line with industry costs.

Passenger Terminal Projects

Dilemma	Solution
Growth in Passengers	Up to 62 Aircraft Gates Right-Sized Terminal & Concourse Space Accommodate Modern Aircraft
Old/Aging Facilities	Upgrade Customer Experience Reduce Operations & Maintenance Costs Improve Resiliency/Reliability
Inadequate Concessions	Increase Customer Choices Upgrade Customer Experience
Insufficient Revenue Opportunities	Provide More Garage Parking Enhance Revenues

Proposed Concept

Passenger Convenience
Customs Accessible to All Carriers
Single Efficient Security Checkpoint
Gates on Both Sides (Shorter Walks)
New Roadways & Entrance
Concourse Can Expand Further
Right-Sized Space

Proposed Concept – Roadways and Larger Parking Garage

An aerial map of a proposed airport terminal and transportation concept, with key areas labeled in yellow boxes. The map highlights the main airport entrance, a closed on-ramp to I-70, eastbound and westbound traffic off-ramps, and a large parking garage and terminal loop. Other notable features include a ground transportation center, MetroLink stations that remain open, and a note indicating no direct connection from Airflight Drive into the terminal loop. The background shows airport runways, roads, and surrounding buildings.

A timeline graphic displaying key phases of an airport project from 2023 to 2032. The timeline begins with the NEPA (National Environmental Policy Act) process in 2023, marked with a leaf icon, and includes FAA approval. Executive program management extends from mid 2023 to mid 2030, overlapping with program management ( mid 2024- mid 2031) and design (mid 2024- late 2028). The concessions program runs from 2026 to mid 2030. Construction begins in 2026 and concludes in mid 2032, marked by a checkered flag icon. Each phase is color-coded, with overlapping bars showing dependencies.

Airfield Projects

An annotated aerial map of an airport's west airfield program, showing taxiways, runways, aircraft parking areas, and a maintenance complex. The map includes labeled taxiways (A, B, C, D, S, U, T, V, S1, S2) and runways (6-24 and 11-29). The maintenance complex is outlined in blue near the top of the image. Various shaded areas indicate infrastructure modifications, with a purple section labeled 'RWY 29 Approach Surface' highlighting an approach path. Yellow lines depict taxiway pathways, and red-hatched areas represent restricted or construction zones.

Proposed Concept — West Airfield Program

A digital rendering of a proposed airfield maintenance and central stores campus, featuring multiple buildings, parking lots, and various equipment storage areas. A large warehouse-style building with multiple garage doors is in the foreground, with rows of yellow maintenance vehicles and equipment neatly arranged outside. Smaller structures and additional parking areas are in the midground, while a larger administrative or operations building is visible in the background near a runway. The facility is surrounded by open land and access roads, indicating its integration with the airport infrastructure.

Proposed Concept — Airfield Maintenance and Central Stores Campus

Are the Consolidated Terminal Program and West Airfield Program projects definitely going to be carried out?

Not necessarily. These proposed projects require airline agreement, funding approvals, as well as state and local permits.

On-Airport Tenant Projects

An aerial view of an airport and its surrounding area, with two highlighted land parcels labeled 'Northern Tract' and 'Brownleigh.' The airport features multiple runways, taxiways, and terminal areas, with adjacent industrial and residential zones. The 'Northern Tract' is situated just north of the airport, near a cluster of warehouses and commercial buildings, while 'Brownleigh' is located southeast of the airport, closer to a residential neighborhood. The map provides a geographical overview of these land areas in relation to the airport infrastructure.

Boeing Site Development for Aircraft Assembly and Flight Testing

Overview

The Boeing Company is expanding its on-airport facilities to support defense-related aircraft assembly and flight testing.

This project will:

Development currently underutilized airport property
Support regional economic development, and
Provide facilities necessary to support national defense requirements.

Boeing plans to expand its current footprint by leasing two parcels of airport property to the north and northeast of the airfield. The project will consist of constructing aircraft assembly and test facilities, including demolition of non-functional structures. New connector taxiways and tow ways will provide access onto the airfield.

Curtiss-Wright Aeroplane Factory Boeing Site Development

Environmental Assessment

An Environmental Assessment (EA) to assess the potential environmental consequences of Boeing’s site development project was conducted. After evaluating the EA, the Federal Aviation Administration issued a Finding of No Significant Impact/Record of Decision (FONSI/ROD)

The EA and FONSI/ROD are available to the public pursuant to Part 1506 of the Council On Environmental Quality Regulations concerning implementation of the National Environmental Policy Act. The EA and FONSI/ROD can be viewed online at Final EA and FONSI ROD for Boeing Site Development at STL. Additionally, the EA and FONSI/ROD can be viewed in person at the STL Airport Administration office, as well as at the Federal Aviation Administration, Airports Division, 901 Locust, Kansas City, Missouri 64106.
