The county public works department provides a number of services to the citizens of the county. The public works department houses a number of services but not every county provides the same services in their counties. For example, a more urban county may not have to provide as much support in snow removal because the cities have their own services. However, a more rural county may not have a public works department at all, instead services will be taken care of through special service districts. Your best bet in understanding the public works department is that when something needs to be fixed, the public works department is the entity that takes care of it.
