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.

The land, which is a former golf course, is being converted into five detention ponds, each of which can hold 100 million gallons of stormwater.
