One of the unique aspects about Iowa City is that it was, from the very beginning, a pre-planned community – worked out on paper, long before the first building was ever built.

Unlike every other city in Iowa, Iowa City had no prior circumstances that made it happen. It came about by a planning committee, looking to build a brand new city in a brand new location. So, when Leander Judson drew up his first version of his 1839 map of Iowa City (below), the only pre-existing conditions he had to work with were 1) the Iowa River, 2) the hills surrounding it, and 3) one beautiful spot already located on one square mile of wooded land where a new capitol building would be built. Everything else would be worked out by city planners.

Under U.S. law, when a new Territory was established in the west, that territorial government was allowed to choose a full section of land – one square mile or 640 acres – to establish its capital. As we mention elsewhere, in May 1839 – Chauncey Swan and his companions staked out an uncharted piece of wilderness located on the Iowa River – legally called Section 10 – Township 79 North, Range 6 – West 5th Principal Meridian in Johnson County. By July 4, 1839, that piece of land – one square mile – had been drawn out by Leander (L.) Judson on the map you see below.

So, while only a handful of people actually lived in Iowa City in July 1839, the future looked bright, and within one year, over half of the 24 streets planned for Iowa City (see map above) were actually being carved out of the wooded hills! In May 1840, for example, writer J.B. Newhall, after a brief visit here, offered this first “inventory” of Iowa City – now with a booming population of 700!
A spacious city hotel, three or four brick buildings, and several others in progress, ten drygoods, grocery, and provision stores, one drug store, one saddlery, two blacksmiths, one gunsmith, three or four coffeehouses, four lawyers, three physicians, one church, and one primary school.

On this page, I’d like to journey with you – beginning in July 1839 and traveling all the way up to today – looking, along the way, at how Iowa City has grown over the years – yet still keeping, in full sight, that original 1839 map of L. Judson’s. Below, you’ll find a selection of nine Iowa City maps – 1854, 1868, 1875, 1892, 1900, 1920, 1930, 2000, and 2023 – and on each of these maps we’ve highlighted, in red, the “original” 1839 Iowa City boundaries. So, are you ready? Let’s jump from July 4, 1839 to…








In 1875, Iowa City’s population had grown from around 5,000 (1868) to approximately 6,500, and A.T. Andreas published his massive Illustrated Historical Atlas of the State of Iowa, which included very detailed maps of both Johnson County and Iowa City. Read more here.
