Like other cities, notably Detroit, confronted with rampant home foreclosures and vacant parcels, Cleveland is not willing to let urban land lie fallow. In the 77-square-mile area within city limits, there are currently 18,000 vacant lots totaling 3,500 acres. While the primary goal is neighborhood redevelopment – including an emphasis on arts and entertainment and building on anchor institutions such as the Cleveland Clinic and universities -- the city has also launched several initiatives to try to enhance urban form despite dwindling population and stalled private-sector activity. Among them: stabilizing vacant lots with urban gardens and native plantings, demolition of structures while maintaining foundations to allow the construction of greenhouses, allowing sideyard expansion, and using vacant lots for geo-thermal wells to heat neighboring structures. But perhaps the most interesting effort is “chicken and bee” zoning – dramatically reduced setback requirements for coops and hives on empty parcels. The city is considering going even further, relaxing rules for raising roosters, turkeys, geese, goats, pigs, and sheep, and possibly including new agricultural overlay districts for more intensive urban farming. Robert N. Brown, director of the Cleveland City Planning Commission, said that zoning would not be changed to accommodate processing or slaughtering, but that urban farming was seen as an appropriate use of the vacant land for now. He made a presentation on the efforts at the annual convening of city planning directors from the nation’s 30 largest cities sponsored by the Lincoln Institute, the American Planning Association, and Harvard University’s Graduate School of Design earlier this week.
