INVESTMENTS

2010 – 2016 Center City Modesplit

What if we made different choices?

Since 2010, Center City Added 45k Jobs – 95% of Net Trips Absorbed by

Non-SOV

• If all 45k drove & parked:

• 1 x 245-story parking

garage, 2450’ high

• Or consume a 16-block

square of downtown with

surface lots

• If 2010 modesplit (35.2%):

• 15,840 SOVs in 87 stories,

870’

• If all net new bike commuters

drove, would fill largest

downtown garage with 1,500

carsSpecial thanks to David Cole, AIA, Mahlum Architects

TDM & One Center City

• TDM is part of the solution

• Continued work to reduce drive-

alone rates, where possible

• Commercial Core SOV Rate:

16.7%

• Keys to success

Safe & inviting biking and

walking infrastructure

Employer investment in

benefits: ORCA passport and
