What is Big Marsh?

Park No. 564

Big Marsh is the vision for Chicago’s Park No. 564, about 20 minutes southeast of the Chicago Loop, just east of Lake Calumet. It’s 278 acres of open space, just a few acres smaller than Chicago’s Grant Park. Big Marsh shares its past with Big Steel and the unique natural history of the Calumet region. Big Marsh creates a new legacy of outdoor recreation and open space stewardship. It’s called eco-recreation.


Friends of Big Marsh is a coalition of organizations, companies, and people who support the development of Park No. 564 as an eco-recreation area that improves the physical, environmental, and economic health and wellbeing of the Calumet region. We recognize that the park’s potential extends beyond reclaiming this misused, neglected landscape for public use. Working in partnership with the Chicago Park District, we’re committed to engaging local communities so that park benefits flow to local residents, businesses and initiatives as we help develop a national eco-recreation destination. We will develop programming that:

  • Improves public health through active and passive recreation
  • Creates and operates a world-class venue for bicycle recreation that benefits all ages and abilities
  • Enhances, monitors and maintains the park’s sustainable natural habitats that allow native marsh inhabitants to return and thrive
  • Stimulates the local economy by creating education and job training opportunities, and attracting regional and national audiences to the park

Dear Friends,

I am pleased to introduce myself as Friends of Big Marsh’s interim executive director, and to re-invite you to share in the transformation now underway on Chicago’s southeast side.

I joined Friends of Big Marsh at the end of 2015, and am thrilled to be with you during this year’s run-up to the park opening and commencement of events and activities at Big Marsh.

I have been a bike guy since I turned seven and rode endless laps around the neighborhood. I worked in a bike shop and as a bike messenger; I’ve ridden and raced mountain, cross, road and ultra distance, and have ridden bikes for touring, commuting, and utility, including transporting my son to school kindergarten through 5th grade. As a Chicago Southland resident, my commutes have criss-crossed the South Side and the Loop; my favorite route passes through Pullman just to the west of Big Marsh.

Professionally I am a lawyer and nonprofit entrepreneur, having been involved in numerous nonprofit startups. Most recently, I was Executive Director of the Chicago Lawyers’ Committee for Civil Rights Under Law from 2010 through 2015, and I stepped away to drive investments to diverse and inclusive neighborhoods. Bringing Big Marsh to South Chicago qualifies as just such an investment.

As the park opening approaches later this year, I hope you will redouble your interest and meet me and other Friends of Big Marsh out there for an event. We need stewards, cyclists, and community leaders to be fully focused on the rich potential of Big Marsh as a resource for all of Chicago, based in the far South Side. Please don’t hesitate to contact me at jay@bigmarsh.org about ways you can plug in and develop that focus.

Thank you,

Jay Readey

Interim Executive Director

Let's Build Big Marsh!

Friends of Big Marsh needs to raise $2.58 million to open Phase 1 — the bike park at Big Marsh — in Fall 2016.

A million dollar challenge triples your impact — Raising nearly $2.6 million for Big Marsh takes an all-in, whole-community effort. Every contribution from $5 to $50,000 will have an impact on opening this park.

And if you give early, that impact is TRIPLED. An anonymous donor is matching every $1 donated to Big Marsh with $2 in additional funding, up to the first $500,000 we raise. A $5 donation becomes $15. A $500 donation becomes $1500 — potentially providing $1.5 MILLION for the park.

Three major partners, Chicago-based SRAM, Inc. the outdoor equipment retailer REI, and PeopleForBikes have provided early support of over $600,000. The challenge grant applies to the NEXT $500,000 we raise—this is YOUR chance to make a difference at Big Marsh!

Become a Chainring Donor — More than 200 people have already donated over $30,000 to the build the park and become a Friend of Big Marsh. That's amazing! A select few of them have decided to go a little further to become Chainring Donors.

For a gift beginning at just $500, a Chainring Donor can have a custom cut metal chainring of varying size engraved with his or her name, family name, or business name to be permanently displayed as a donor on site at Big Marsh.

With your gift, you choose to have an 8" climbing ring, a 12" middle ring, or an 18" big ring mounted to the donor wall placed in the park's main bike plaza, prominently displaying your role to transform this landscape into beautiful, healthful, sustainable outdoor recreation.
