Opening the official parcel viewer
Go first to the Ohio Statewide Parcels layer in ArcGIS Map Viewer; it covers each tax parcel around South Bloomfield and Williamsport.

Out toward Ashville, a pop-up or side panel usually lists the owner of record, assessed acreage, a parcel ID and often a sale date.
Beyond the mapped zones
Creeks and ditches near Williamsport may not have detailed mapping, so look for water marks and debris lines. Wetlands near Commercial Point can limit building even outside a flood zone; the National Wetlands Inventory mapper shows mapped wetlands.
