North, South, East, West Toledo Boundaries

Sorry if this has been answered before, but I did do a search on here and Google'd the question before I posted it.

I am looking for information on what the widely accepted (or OFFICIALLY recognized) boundaries are for N, S, E, W and central Toledo are, seeing as we don't actually reference them in TRUE geographic terms. I understand the why, I just want to be able to make a map showing where these boundaries are.

I am also making a map of all the Toledo Neighborhoods and their boundaries. I found this link: http://www.city-data.com/nbmaps/neigh-Toledo-Ohio.html but as you can see, it doesn't show the what the street boundaries are. Does anyone know what city department can provide this information?

Thank YOU!
