Do you support developing former industrial mine sites into new residential parks and housing communities?

Henderson celebrated the grand opening of Greenbow Park on September 10, 2026, situated within the 1,146-acre Aries master-planned community. The project transforms the site of the former Three Kids Mine, which produced manganese for decades.

Why it matters

The site required a $257 million environmental cleanup to address contaminants like arsenic, lead, and asbestos before development could proceed. This remediation allows for the construction of more than 3,000 residential homes in the area.

The redevelopment spans 1,146 acres, including a 410-acre impacted zone that underwent extensive decontamination. Developers are set to 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

This state agency is responsible for overseeing environmental remediation and ensuring public safety at hazardous site redevelopments.

Del Webb

A well-known developer specializing in active adult communities that is slated to begin home sales at the project site in 2027.

The details

Developers fronted the full cleanup cost, which is now verified as completed by the Nevada Division of Environmental Protection. The broader Aries master-planned project will feature future amenities such as splash pads, play areas, and sand volleyball courts.

The Three Kids Mine operated from 1917 to 1961.
Manganese storage at the location ended in 2003.
The Aries community held its grand opening on September 10, 2026.
Del Webb is expected to begin selling homes in 2027.

Culture Shift

This development follows the brownfield redevelopment tax incentive framework that encourages private investment on formerly industrial land. By repurposing the site, the project reflects a broader societal shift toward prioritizing urban infill over undeveloped land expansion.

Local residents gain new park space and future housing options within the Aries community. The project signals a transformation of a long-vacant industrial area into a functional residential zone.

The takeaway

The successful transformation of the former mine site highlights how significant financial investment in cleanup can unlock large-scale residential growth. Residents should keep an eye on 2027 for the official launch of new home sales in this redeveloped area.
