Sustainable Land Lab

The Sustainable Land Lab is a living laboratory of strategies for creatively reusing vacant land. The initiative is a joint effort of the City of St. Louis and Washington University in St. Louis.

Sunflower Project

The Sustainable Land Lab generates and tests ideas that reframe vacant land as an opportunity. The first phase of the Sustainable Land Lab was a competition in fall 2012 that challenged teams to propose innovative projects that transform vacant lots into assets that advance sustainability.

Unlike many idea-generating competitions, the Sustainable Land Lab required winning teams to implement and test their proposals. The first set of projects are all located near the Crown Square development in Old North St. Louis and were implemented in 2014.
