What happened
East Henderson has a new park inside a neighborhood rising on a former mining site, the Las Vegas Review-Journal reported. Greenbow Park sits near Lake Mead and Lake Las Vegas parkways in Aries, a master-planned community being built where the Three Kids Mine once operated.
City officials attended a grand opening for the Aries community at the park on Sept. 10, according to the Review-Journal. Greenbow Park is one of several parks planned for the community.
What the park includes
Amenities at Greenbow Park
The Review-Journal reported that the park offers views of the Strip, a large field, playgrounds and a shaded picnic area. It also has four pickleball courts and a paved loop trail.
More parks planned
Homebuilder PulteGroup previously said Aries spans more than 1,100 acres and will include several parks. Other parks will feature sand volleyball courts, splash pads, play areas and barbecue pits, the Review-Journal reported.
The mine's history and cleanup
Decades of manganese production
State officials say the Three Kids Mine produced manganese for the U.S. government from 1917 to 1961. The Nevada Division of Environmental Protection previously said manganese was stored at the site until 2003. During the mine's operation, manganese ore was mainly used in building ships and tanks during both world wars, according to the Review-Journal.
Contamination and remediation
The division, which oversees the environmental cleanup, says the redevelopment project area covers 1,146 acres, with 410 acres making up the "impacted area" of the former mine. Contaminants found at the site included arsenic, lead, petroleum hydrocarbons, dioxins and asbestos.
The division previously put cleanup costs at about $257 million. Anthony Molloy, Henderson's director of redevelopment, economic development and tourism, told the Review-Journal in June that all remediation work had been completed. He said there was no environmental contamination anywhere on the former mining site.
How the cleanup is paid back
Developers paid the cleanup costs up front, the Review-Journal previously reported. In return, they are eligible to receive 85 percent of tax revenue generated during the project's first 25 years and 80 percent from years 26 to 45.
