Thank you for using Improve Detroit. Utilizing the category "Post to Neighbors" functions more like an online blog. In order to route a request directly to a department, you must select one of the specific categories that are available (for example, "Illegal Dumping" or "Abandoned Vehicle"). The City's website provides information on how to report many concerns:

Blight may be reported via telephone to 313-224-6000. If you're trying to report illegal dumping, please use the proper category to do so. Thank you.
