The city of Henderson opened Greenbow Park on September 10, 2026, marking the first phase of the massive 1,146-acre Aries master-planned community. The project transforms the former Three Kids Mine site into a residential hub expected to house over 3,000 homes.
Why it matters
The development represents a major brownfield reclamation, as developers spent $257 million to remediate 410 acres of land contaminated by heavy metals and hazardous materials. This cleanup ensures the area is safe for residents before residential construction begins.
The redevelopment spans 1,146 acres and includes a 410-acre cleanup area where contaminants like lead and asbestos were removed. Developers will receive 85 percent of tax revenue for the first 25 years and 80 percent from years 26 to 45.
The players
Nevada Division of Environmental Protection
The state agency tasked with regulating environmental safety and overseeing the site remediation process.
Del Webb
A well-known developer of master-planned communities that is scheduled to begin selling homes at the site in 2027.
The details
To prepare the site for residential use, developers fronted the entire $257 million cleanup cost, working under the oversight of the Nevada Division of Environmental Protection. Remediation efforts successfully addressed legacy materials including arsenic, petroleum hydrocarbons, dioxins, and asbestos left over from manganese mining operations that spanned 1917 to 1961. With the environmental cleanup now complete, the site is designated for the new Aries community, which will eventually feature over 3,000 homes.
Timeline
1917 to 1961: The Three Kids Mine produced manganese.
2003: Manganese storage operations ceased at the site.
September 10, 2026: Greenbow Park held its grand opening.
2027: Del Webb is expected to begin selling homes.
The Home Front
This project follows a pattern of large-scale remediation set by the Environmental Protection Agency's Brownfields Program to repurpose former industrial mine sites. Converting decommissioned industrial land is a key strategy for expanding local housing inventories in growing cities.
Prospective buyers interested in the Aries community should monitor for sales information expected to launch in 2027. Future residents should keep in mind that the site has undergone extensive, completed environmental remediation overseen by state regulators.
The takeaway
The transformation of the former Three Kids Mine demonstrates the long-term potential of large-scale brownfield reclamation projects for new housing. Those considering a purchase in the Aries master-planned community can review the project scope at the city planning office.
