Bronx, N.Y., and anywhere / youarethecity
According to the New York Department of City Planning, more than 6 percent of the city’s land is vacant, adding up to a total of approximately 11,700 acres of underutilized land. Many of these lots are plagued with contaminated soil as a result of previous constructions and industrial uses. To educate property owners about how they can initiate cost-effective toxic cleanup, architect and planner Kaja Kühl created the Field Guide to Phytoremediation, a do-you-it-yourself (DIY) handbook that is available online and as a downloadable pamphlet.
