ABOUT US

OUR MISSION

At 5th Square, we believe that cities are for people - and people need infrastructure, transit, housing, and public space designed with equity and sustainability in mind. Rooted in grassroots action, we activate neighbors to drive policy, partner with communities, and hold decision-makers accountable so that Philadelphia becomes a city that works for all of us.


Since our founding, our mission has been to advance a vision of a more accessible, sustainable, and equitable Philadelphia. We build coalitions across neighborhoods, support meaningful reforms, and elevate the voices of people who are too often excluded from shaping our shared future.

OUR FOCUS AREAS

Where we’re driving change to make Philadelphia more accessible, sustainable, and equitable.

Better Public Transportation

Philadelphia suffers from longer commutes and more congestion than most large cities in the US. We believe the solution to these mobility problems lies in fast, affordable, accessible, and safe public transportation.

Safer Streets & Vibrant Public Spaces

Philadelphia currently gives far too much space to cars and prioritizes the convenience of drivers over the health and safety of everyone else. We advocate for roadway safety policies so that our streets and other public spaces are safe and accessible to all residents, regardless of race, age, gender, disability, or any other identity.

Homes of All Shapes & Sizes

Most people in Philadelphia can't afford a new home on the market today; and most of the iconic, affordable housing stock of Philadelphia would no longer be legal to build. We believe in building more housing and seek to reduce housing costs to foster accessible, walkable communities in which all Philadelphians can reside, regardless of income.

FOR IMMEDIATE RELEASE Contact Information: 5th Square Advocacy Corinne Lagermasini 445-465-9378 corinne@5thsqadvocacy.org 5th Square Advocacy Applauds SEPTA’s Release of Accelerate — Long-Range Vision PHILADELPHIA, PA, September 22, 2026 — 5th Square Advocacy applauds the Southeastern Pennsylvania Transportation Authority (SEPTA) for releasing their new long-range vision, Accelerate . The report charts a path for SEPTA to better serve the way people live, work, and travel today. Corinne Lagermasini, Executive Director of 5th Square Advocacy, says, “With this announcement, the path is set for SEPTA to transition into a world class public transit service that meets riders where we’re at.” “This plan shows that with sufficient investment, we can have a world-class transit system. We need buy-in from State and Federal government and the political will to not just fund — but also upgrade — our public transit system.” “Frequency means freedom — and providing frequent service to over a million more residents will be revolutionary. Philadelphia already has one of the most extensive rail networks in the country. Implementing 15-minute frequency on regional rail lines would be akin to a subway expansion and would transform access for thousands throughout our region.” “We can’t ignore SEPTA’s $10.2 billion state of good repair backlog. We have a legacy system that’s seen decades of under-investment. We have too many stations that lack accessibility, an aging rail fleet, and a system that treats transit and regional rail riders differently.” “Philadelphians deserve reliable, modern public transit. SEPTA should also have a vision for our current rail transit deserts along Roosevelt Blvd and the Navy Yard. We also need a concrete timeline for these changes.” Transit Forward Philadelphia Coalition Manager Stephen Bronskill said, "This is a make-or-break moment for public transit in Philly and across PA. Our state leaders can pass a transit funding solution that not only avoids devastating service cuts next year but also invests in initiatives like reimagining regional rail, delivering the safe, reliable, frequent service Philly and communities across the commonwealth deserve.” Transit For All PA Statewide Campaign Manager Connor Descheemaker added, “All transit riders in PA deserve to see a better future ahead of them. Our public goods, including transit, cannot be resigned to stagnation and loss. That’s why we continue to fight for real investment in service restoration and expansion: exactly what SEPTA’s strategic plan is proposing.” 5th Square Advocacy is a 501c4 nonprofit organization mobilizing neighbors to advocate for people-centered communities. We fight for policies at every level of government that promote abundant housing, safe roadways, and accessible transit. Learn more at www.5thsqadvocacy.org
