Ann Arbor Area Civic Document Repository

Ann Arbor City Hall has been involved in legal battles with FDD (Footing Drain Disconnect) for a long time. I'd like to know the total cost that these lawsuits have cost the city. This total cost need not be an exact figure, but an estimate would do. I'm not looking for the cost of the infrastructure, but I'm looking for the costs to the legal/law side to this issue. If possible, an estimate of the number of hours that the city lawyers have spent on this issue would be nice to have as well. Thank you for listening to my request
