Lakewood Issue 47 Fails on Recount

The West End Development Project (Ballot Issue 47) in Lakewood has been voted down on recount and the Cuyahoga County Board of Elections has certified the results. However, the difference between yea and nay was narrow and another recount is required in December. This news is from local radio station WTAM and I really don't understand why there has to be another recount.
