What drives Atlantic’s History grade

B+
HistoryA character grade: shown, never part of Atlantic’s overall grade.
Iowa towns list more on the Register than most of the country (a typical Iowa town has 9.1 per 10,000 residents, the U.S. 2.4), so Atlantic’s 14.8 sits above most of its state (65% of Iowa towns have fewer) while its 10 historic buildings outnumber those of 76% of U.S. towns.
How sure. Graded on any two of the three inputs instead, the letter would range from B− to A. The pre-1940 share is a Census survey estimate (±5.9 points). Two sources give 1868.

What stands out about Atlantic’s past
Read from the archive, the National Register and the record. The page puts what stands out first.
Fire insurance maps drew every building, what it was made of and what it was used for, so insurers could price the risk of fire. Pick a year, then a sheet.
Atlantic was founded in October 1868 by Franklin H. Whitney, B.F. Allen, John P. Cook, and others. While historians cannot agree on how Atlantic got its name, local legend tells that the founding fathers estimated that the town was about halfway between the Pacific Ocean and the Atlantic Ocean, so it led them to flip a coin and, clearly, Atlantic won. The nearby Rock Island Railroad was important in deciding the actual location of the town, and to this day, the old depot, built in 1898, sits at the north end of Chestnut Street. Today, the depot serves as the offices of the Chamber of Commerce.

It was situated about three miles east of Atlantic, on a beautiful and level elevation of land, and bade fair to be a prosperous and thrifty city at no distant day, with broad streets, public square and park, but was cut off in its infancy by the Rock Island railroad,
