Businesses named in the atlases

25 businesses

Every Sanborn volume opens with a printed index naming the town's mills, tanneries, hotels and works by proprietor. Those indexes were read off the scanned sheets by machine and then matched to each other, so a business surveyed four times appears here once, with the years it survived. 7 of these 25 were named in more than one atlas. Each carries a crop of the line it was read from: the spelling is the recogniser's and the 1880s lithographer's, and the scan behind it is the proof.

April 2003HailPowell$65,000,000Hail up to the size of golf balls affected the north side of the Columbus metro area and southern Delaware county. Hail was extensive from Dublin, through Worthington and Powell, to Westerville. Trees and shrubs were stripped of their foliage and cars and homes sustained significant hail damage. The hail covered the ground in some locations up to six inches deep in Worthington in northern Franklin county and near the Polaris Mall in southern Delaware county.
March 2024Tornado (EF1)Stratford$1,000,000The tornado developed in central Delaware County near U.S. Route 23. As the tornado crossed U.S. Route 23, it strengthened and widened and caused more widespread structural damage as it crossed the Olentangy River. Even more significant damage occurred as it moved along Berlin Station Road and in other areas of Berlin Township. Along this portion of the track, a number of homes sustained siding and roof damage and numerous trees were snapped and uprooted. Several barns were also destroyed. In the vicinity of Olentangy Berlin High School, parts of the school campus and athletic fields were damaged, signs were bent over, and several free-standing transmission towers were felled. In this area, maximum wind speeds were estimated to be around 110 mph.||The tornado crossed Alum Creek Reservoir and moved into neighborhoods southwest of Sunbury and west of Galena, where it caused widespread and significant tree damage and a large number of homes had windows blown out, roofs partially removed, and power poles snapped. Damage in these areas was consistent with wind speeds from 95 to 105 mph. ||As the tornado moved through the Galena area, there was a complex mix of straight-line wind damage through southern parts of the town of Galena with tornadic damage embedded across the north side of Galena. The damage field through this area was notably wide.||The tornado entered Licking County at 2022EST, about 3 miles SSE of Condit, and continued to moved east-southeast across much of northern Licking County before ending at 2050 EST, about 1 mile south-southeast of St. Louisville.

Much of the cinder block collapsed, while roofing of this structure with some of the attached cinder block and other bard roofing and walls was lifted across Highway 257 where much of the material was wrapped around trees along the Scioto River. Large portions of the barn roofing was lofted over the tree line along the Scioto River and deposited in the back yards of residences along River Road, on the east side of the river, a distance of two tenths of a mile away. Tree damage along the south side of the brief tornado track was lying in a northeast orientation which was inward toward the tornado track which confirms the convergent circulation. Other damage along the path included snapped large trees, complete destruction of a small shed, and large amounts of debris wrapped around trees.

The townships, in 1908

151,763 words

20th Century History of Delaware County, Ohio and Representative Citizens devotes a chapter to each township: its boundaries and streams, who settled it and when, the mills, the schools and the churches. All 2 are reproduced here in full. Each row shows the township's own shape and where it lies in the county, drawn from the Census Bureau's boundary. Which settlements belong to which township is computed from that same boundary, not taken from the book.
