While the end result would look little like Texcoco’s past, it could revive something more fundamental: the Valley of Mexico’s long-dormant history of building in step with natural systems. And Echeverria’s team hopes the park can also help foster economic development by developing native plant nurseries and reviving cultural practices facing extinction, including the harvest of spirulina algae. With a budget of $1 billion, Texcoco Park is repurposing the structural skeletons and concrete gorges left behind by the airport construction to create artificial lakes and habitats intended to host human visitors and an unprecedented mix of species. Instead of seeking to roll back the clock, Echeverria is creating an artificial wetland that aims to transform the future of the entire Valley region, drawing lessons from both Tenochtitlan and modern Mexico City on how thriving cities can coexist with flourishing ecosystems. In this vast footprint, the president decreed, the city would build one of the world’s biggest urban parks, a project he dubbed a “new Tenochtitlan.” To oversee what would become known as Lake Texcoco Ecological Park (PELT), he appointed Iñaki Echeverria, a Mexican architect and landscape designer who had spent over two decades advocating for the site’s restoration.Įcheverria’s vision for the park is part of a wave of projects that have upended the traditional goal of ecosystem restoration: returning ecosystems to the state they were in before humans damaged them. Left behind was an eerily empty landscape bigger than Paris, circled by the sprawl of Greater Mexico City.

Then, in a post-election referendum launched by López Obrador’s party, the public had voted to scrap it (though critics claimed the results were unrepresentative, with just one in 90 Mexican voters casting a vote). During his campaign, López Obrador had railed against the project’s management for overspending and corruption. Weeks after President Andrés Manuel López Obrador took office in 2018, the combative leftist leader enraged international investors and Mexico’s business community by canceling the airport, which was already around one-third complete.
