Urban Golf Course-Turned-Wetland Cuts Hurricane Harvey Flood Impacts

The Takeaway: The project, supported by Texas’ coastal zone management program, will provide recreational opportunities and slash flood risks for thousands of area homes.

As Hurricane Harvey bore down on the Texas community of Clear Lake, a reclaimed urban wetland, transformed from an abandoned golf course, performed exactly as it should—acting as a sponge to keep floodwaters away from area homes. The 200-acre wetland and green space, named Exploration Green, protects this land from commercial development. It was supported by the Texas General Land Office’s Coastal Management Program through a grant from NOAA’s Office for Coastal Management.

Exploration Green received a 2018 Excellence in Green Infrastructure award from the U.S. Environmental Protection Agency and National Association of Flood and Stormwater Management Agencies.

Once Exploration Green is completed, up to 3,000 homes will no longer reside in “100-year” or “500-year” floodplains that carry greater risks of flood damage. Five large detention ponds under construction will hold an estimated one-half billion gallons of stormwater. In addition, studies supported by the state’s coastal management program will document water quality changes provided by its 40 acres of restored wetlands. Other community benefits will include miles of hike and bike trails, athletic fields, bird habitat islands, native grasslands, and thousands of trees.

This reclamation effort is being implemented by the Galveston Bay Foundation. (Original story 2016/ updated 2018)
