39 North is located in St. Louis County within the City of Creve Coeur and borders the City of Olivette to the east.  The 600 hundred-acre innovation district is anchored by the Donald Danforth Plant Science Center, BRDG Park, the Helix Incubator, Bayer Crop Science, and the Yield Lab.


The 39 North Master Plan funded by a $500,000 grant from the U.S. Department of Commerce, presents a vision for an innovation district in St. Louis County that is uniquely positioned to advance the region’s global leadership in plant and life sciences. The district will be geared toward lifestyle preferences often sought by highly-skilled employees, including mixed retail, residential and office space connected by walking and biking trails and green space.


  • Strengthen corridors and establish new traffic patterns
  • Connect assets and opportunity sites
  • Establish a cohesive development framework
  • Create a mixed-use center of activity
  • Communicate the district

In the near term, dedicated staff at the St. Louis Economic Development Partnership will manage the implementation of the plan for 39 North in coordination with a steering committee of essential stakeholders, all of whom shaped the Master Plan. In the longer term, an empowered nonprofit entity will be created to ensure the continuation of the District’s mission.
