Should your local government prioritize converting industrial land into public parks and green spaces?

Denver has officially opened the new Carpio-Sanguinette Park and Heron Pond Open Space. The $39 million project repurposed land formerly occupied by the Northside Wastewater Treatment Facility.

Why it matters

The development provides critical recreational space while addressing long-standing industrial contamination in the area. It serves as a major investment in environmental justice and community health for the city.

The project encompasses 80 acres of land, including 20 acres dedicated to a newly built levee for stormwater management. The site, which was historically contaminated with arsenic, cadmium, and lead, is located 2 miles from the Suncor Energy complex.

The players

Carpio-Sanguinette Park and Heron Pond

This is a newly opened 80-acre public space in Denver designed to improve community access to nature.

Northside Wastewater Treatment Facility

This was the former industrial occupant of the site before its remediation and conversion into parkland.

The details

The site unites four distinct parcels of land through a comprehensive environmental cleanup and new accessibility provided by the 51st Avenue bridge. Designed with community input, the park features a BMX pump track, a playground, and bird observation areas while preserving historical graffiti walls.

Residents can now access the park via the new 51st Avenue bridge connection. The site offers bird watching and BMX facilities, providing a new recreational destination for families in the Denver area.

The takeaway

The transformation of this site demonstrates how cities can convert toxic legacy industrial zones into functional green infrastructure. Community members should note that the park includes specific areas for bird observation and active sports like BMX.
