About Exploration Green

In Southeast Houston, dedicated groups of volunteers are transforming a defunct golf course into an innovative stormwater detention center and green space.


Exploration Green provides an integrated, natural solution for catastrophic seasonal flooding holding up to 500-million-gallons of stormwater while also serving as a nature preserve and recreation area. Located near NASA's Johnson Space Center, this 200-acre urban green space provides the community with countless opportunities to explore, offering 40 acres of both wetlands and permanent detention lakes, home to over 1,000 native species.
