I have an alley adjacent to my property, beside my garage. The alley is in bad shape but my request for the city to repair and/or resurface the alley was rejected since they will only repair it if there is a sink hole[[s).

1) Is there anything else I can do to get the city to fix city owned property such as the alley?

2) Failing 1), I've read here and there alley's can be privatized. If I acquire the alley as my own, I can make repairs on my own. However, I cannot find anything on the City of Detroit on how to do this.
