LDCs vs. BIDs

I am currently interning at a planning department within a small town. The town contains two industrial parks, one of which is relatively successful with a low vacancy rate, while the other is just the opposite. We are looking to improve this region by implementing a Master Plan. One of our strategies is to start either an LDC or BID to help improve the area. I've found quite a bit of information online on determining whether or not to start a BID and the steps in actually implementing one. However, I haven't been able to find much information on Local Development Corporations. Does anyone have any good resources concerning these, including the differences between an LDC and a BID, and the strategies for implementing an LDC? In addition, I'm a bit skeptical about implementing a BID since the parks are occupied by manufacturers not engaged in on- site sales. My impression is that BIDs are suppossed to be implemented in order to increase local business economics. I don't see how this would work, considering that the owners of the vacant parcels would most likely be resistant to joining a BID since they don't have a tenant to pass the dues unto. Does anyone have experience with improving industrial parks using these or other strategies? Thank you.
