Exploration Green, named in honor of the community’s local exploration legacy and its proximity to Johnson Space Center, is transforming a former golf course into five detention ponds that can each hold 100 million gallons of stormwater (the equivalent of 750 Olympic-sized swimming pools). In addition, Exploration Green will also serve as a nature park comprising 105 acres of natural habitat with wetlands and native grass land areas, six miles of hike-and-bike trails, two athletic fields, and other amenities.
Phase 3A of the project features a 16.6-acre detention pond, 11.4 acres of natural habitat with wetlands, and 0.80 miles of hike-and-bike trails. Phase 3B, which will be completed next summer, includes a 11.3-acre detention pond, 12.2 acres of natural habitat, and 0.67 miles of hike-and-bike trails. Phase 4, currently under construction, features a 22.5-acre detention pond, 9.8 acres of natural habitat, and 0.99 miles of hike-and-bike trails. The first and second phases were completed in April 2018 and September 2020, respectively.
CLCWA, the local provider of water, sewage collection and treatment, and storm drainage services, is spearheading the project. Exploration Green Conservancy, Inc., a nonprofit organization, is serving as CLCWA’s partner to develop and preserve the project’s green spaces. Lockwood, Andrews & Newnam, Inc. (LAN), a national planning, engineering, and program management firm, is the project’s design engineer.
Building the detention ponds has turned out to be beneficial to the community. During Hurricane Harvey, although only 80 percent of the Phase 1 pond was excavated at the time of the hurricane, it helped detain 100 million gallons of water, protecting at least 150 homes from flooding. The project also protected the community during Hurricane Nicholas and Tropical Storms Imelda and Beta. Ultimately, when all five phases are completed, Exploration Green will protect up to 3,000 homes.

“Exploration Green has transformed Clear Lake from a flood-prone community into one of the most flood-resilient communities in Texas,” said Wayne Swafford, P.E., LAN’s President. “In addition, it is creating a healthy, sustainable neighborhood for its residents.”
Situated in the center of the Clear Lake community, this project provides green space and trail access for strolling, walking, jogging, or biking. Nearly 70 percent of the 40,000 people living in the direct Clear Lake area will be within walking distance of Exploration Green, and the remaining 30 percent will be less than a mile from one of the sections.
Finally, the wetlands and native trees, grasses, and wildflowers have provided a habitat for fish, birds, and other wildlife. iNaturalist reports indicate that hundreds of birds, plants, insects, and reptiles have been verified at Exploration Green.
