Building the River Ring

Great Rivers Greenway Plan Update
St. Louis, Missouri, USA

“The River Ring is one of the most exciting and durable legacies we can create for our region. It is a true celebration of our unique and wonderful rivers, our cultural heritage.”

David Fisher
Former Executive Director, Great Rivers Greenway District

HOK led the process to update the Great Rivers Greenway District’s regional greenway plan.

Great Rivers Greenway adopted a master plan for developing a network of greenways throughout St. Charles County, St. Louis County and the city of St. Louis in 2004. HOK collaborated on the initial plan, titled “Building the River Ring,” for this interconnected system of nearly 50 greenways linking three counties, two states and an area of 1,200 square miles.

In 2011, 10 years after a citizens’ initiative created the Great Rivers Greenway, HOK helped the district update its master plan. Using the original greenway plan as a foundation, our plan update provides a set of 40 strategies for building, promoting and sustaining the River Ring.

HOK’s greenway plan update identifies public, private, non-profit and citizen-based partnerships that will allow the district to maximize each dollar it receives when carrying out the plan.

Great Rivers Greenway is currently implementing projects on 17 distinct greenways in the St. Louis region. Since 2001, the district has collaborated with 100 partner organizations to preserve 1,500 acres of land, build 90 miles of off-street recreation trails and designate almost 80 miles of on-street bikeways.
