Future Integration - GTAP
Guiding Principles

Goals

• Reduce environmental impact
• Reduce roadway
congestion
• Support customer
choice
• Social equity
• Generate revenue
for sustainable
airport

• 50% scope 3
reduction
• 15 minutes tower to
curb
• 30% private vehicle
pick-up/drop-off
• Social equity
• Financial
sustainability

Strategies and Tactics
SAMP

GTAP
Operational
Contracts
Taxi, TNC,
other GT

e.g. roadway relocation,
Widen Arrivals
Approach
e.g. first/last mile,
access fees, express
bus
e.g. rematch, TNCs on
Arrivals, garage
utilization
e.g. e-KPIs, driver income,
guaranteed min. wait time

Supports Ground Transportation Access Plan (GTAP) Strategies

Future Integration
Additional Garage
Access Ramp

Roadway Improvements
(6 lanes, raised profile)

Busway & Stations

Support Anticipated Future Work - Build it Once
7

Key Findings
• Additional lanes required to support Main
Garage access ramps
- Either private vehicles or commercial ground
transportation services

• Relocating Rental Car bus curb further north
improves curbside and busing operations
Completed Pre-Design and Operational Analysis for Multiple Improvement Alternatives
8

Key Findings
• Need to raise Arrivals roadway profile
- Supports anticipated SAMP Near-Term Project
roadway improvements (2-3 years after opening)
- Substantial construction impacts with
temporary roadways and relocation of major
utility systems
Completed Pre-Design and Operational Analysis for Multiple Improvement Alternatives
9

Recommended Alternative
Relocate Rental
Car bus curb
Supports three
Garage access ramps

Widen to six lanes
(southbound)
Widen to four lanes
(Arrivals and Garage)

Complete Tunnel
Seismic Work

Raise roadway profile
(forward compatible)

Meets Main Terminal Access Requirements through 54 MAP and beyond

Project Risks
SAMP Near-Term Environmental Review
• Design will proceed at risk and concurrent
with environmental review effort
• Construction authorization cannot be
pursued until environmental review is
completed
Widen Arrivals Roadway is first SAMP Near-Term Project
14

Project Risks
Airport Utilities Master Plan
• Many facilities and systems located within
roadway corridor
• Phased design and construction approach to
accommodate likely scope changes
Targeting Completion of Key Airport Utilities Master Plan Elements by Q4 2019
