Porter County City and Village Plat Maps

Numerous plat maps of cities, villages, and additions are available on this website. Note that several plats were surveyed and recorded for villages that never came into existence; most of these plats were recorded very early in Porter County's history and were platted as speculative land investments that did not materialize. Other plats were published for small villages that existed but then later became depopulated, largely due to the fact that railroads became less important as a factor in creating and maintaining communities.

Porter County Land Patent Maps and Name Index

Land patents were issued by the General Land Office, conveying property held by the federal government to individuals; these individuals were referred to as patentees. The federal government's original survey of Porter County has been scanned and made available by the Porter County Surveyor's Office. The Porter County Land Patent Name Index provides more than 2,600 land patent records for all land contained within the boundaries of Porter County, Indiana, as well as a link to a copy of each original land patent document. You can also view each township's land patentees by viewing township plat maps that are based on General Land Office data.

Early Porter County Maps

Few maps of Porter County exist that were produced prior to 1860. The following maps are the earliest known county-wide maps known to exist.

        Solon Robinson's Descriptive Maps of Unsold Lands was likely
        produced in 1838. Robinson was the first settler to make a claim on land
        in the area that later became Crown Point, Lake County, Indiana.
        He was very active in promoting agriculture and the development and
        settlement of Northwest Indiana. Robinson's map, based on original
        survey maps prepared by the United Surveyor Generals Office, is
        particularly interesting in that the extent and distribution of prairie lands
        and wetlands prior to development of the two counties have been
        depicted on the map. Note that only the far western portion of Porter
        County is shown on Robinson's map. The map was engraved by
        Doolittle & Munson, engravers and copper plate printers, who were
        located at the corner of Main Street and Fifth Street in Cincinnati, Ohio.
        Solon Robinson was born October 21, 1803, in Tolland, Tolland County,
        Connecticut, and died November 3, 1880, in Jacksonville, Duval County,
        Florida. He is buried in Maplewood Cemetery located in Crown Point.

        E. P. Abbot's Sectional Map of Porter County, Indiana, was
        produced in 1855. Ephraim Putnam Abbot, a civil engineer and surveyor,
        prepared his map by compiling information from United States surveys.
        The interesting feature of this map is that it locates the mills, both saw
        and grist, operating in the county at this time. Also featured on the
        map are such villages as City West, New City West, Calumet (later
        known as Chesterton), Bailey Town, and Tassinong. The Abbot map
        was engraved by Gibson & Company of Cincinnati, Ohio. Abbot, who
        served as a Captain of Company E, Third Regiment Ohio Infantry,
        during the Civil War, was born September 21, 1833, in Muskingum
        County, Ohio, and committed suicide by shooting himself at his home
        in Shawnee, Perry County, Ohio, on September 19, 1878. He is
        buried in Greenwood Cemetery in Zanesville, Muskingum County, Ohio.

Valparaiso National Bank/First Trust Co. Porter County Map

Sanborn™ Fire Insurance Maps

The Sanborn Map Company of Pelham, New York, developed extremely detailed maps of municipalities located throughout the United States for the purpose of providing information for the underwriting of fire insurance. In particular, the maps aided fire insurance agents in ascertaining the hazard level associated with a specific property. Maps provide details such as size, shape, and type of construction of dwellings, commercial structures, and factories, as well as fire walls, locations of windows and doors, sprinkler systems, and roof types. In addition, property boundaries, widths and names of streets, current building usage, and house and block numbers are provided on the maps. The Indiana State Library, as well as several other libraries located in Indiana and elsewhere, maintain a microfilm set of Sanborn™ fire insurance maps for Indiana municipalities dating from the 1880s to the middle of the 1950s. The microfilm can be obtained through interlibrary loan services at most local libraries and found through an OCLC WorldCat search (use the following keywords in WorldCat: Sanborn fire insurance maps Indiana). Once obtained through interlibrary loan, a microfilm printer or microfilm scanner can used to produce either hardcopy or digital copies of the microfilmed maps. Below are the Sanborn™ fire insurance maps available for Porter County municipalities:
