Erma - Contacted code enforcement in May about neighborhood property that is abandoned, perhaps bank owned. The weeds are over 5 feet high and there are vehicles on property that may have been left there by other neighbors. Code official responds that a citation was sent to the owner. Now it's approximately seven weeks later and nothing has been done. Sending a citation accomplished nothing; the taxpayers want this property cleaned up. How do we make this happen?
