In 2019 we had 81 demonstration houses! 
Demonstration houses (DHs) are the backbone of our effort to create a culture of Curb Cleaning. DHs own or rent property in the Como neighborhood. They demonstrate the practice of weekly removal of leaf litter that accumulates in street gutters that border their property. This is done throughout leaf drop season – October through November. By engaging in this practice collectively, across many Como neighborhood blocks, we are able to synchronize and maximize our water pollution prevention impact.
Beginning in 2020, we are no longer promoting “demonstration houses” as distinct from other neighbors who engage in Curb Cleaning. However, we are hopeful our current network of DHs will continue to check in with us at the end of November to add their efforts to our measurement of water pollution prevention. And we are very proud of our DHs – they lead by example throughout the Como neighborhood, helping us create a community-wide practice of curb cleaning.
