Lonza Patrick has lived in the Walnut Park East neighborhood for more than 50 years. He’s seen the area take repeated turns for the worse, as nearby properties became vacant and neglected. “Oh man, have I had experiences,” Patrick said. Patrick wants to see the neighborhood improve and it might, with the unrolling of a new initiative to demolish vacant properties to build green spaces. It’s headed by the Green City Coalition, which consists of the Missouri Department of Conservation, the Missouri Botannical Garden and several other St. Louis-based nonprofits. The Metropolitan St. Louis Sewer District provided funding to the coalition this year to knock down about 1,000 derelict, Land Reutilization Authority-owned buildings in the Walnut Park East, Baden and Wells Goodfellow neighborhoods.
