Lockport Historic District
Also known as: Canal and Downtown Area; See Also:Will County Historical Soci

Why it's listed
Lockport's canal and downtown district was planned in 1836 by surveyor Joseph Wampler for the Illinois and Michigan Canal Commissioners, and the town served as canal headquarters from 1838. State Street, 100 feet wide, was laid out parallel to the waterway and only half a block away, a design the nomination says is unmatched among nearby canal towns. The district covers about 31.6 acres of mostly commercial buildings, some of frame or brick but most commonly of locally quarried limestone. Canal-related structures include the Canal Office and Superintendent's home, now a museum, the Hyland Building and the Lockport Iron Works. A fire in 1895 destroyed the east side of State Street between 9th and 10th Streets, and that block was rebuilt in 1895 and 1896. Despite first-floor alterations and two areas of intrusion, the district keeps the look of a 19th-century business district with a continuous townscape.
Significance in brief: The nomination argues the district is a well-preserved example of a 19th-century canal town. Its main street, State Street, runs parallel to the canal and only half a block from it, a layout the form says no other canal town in the area shares. Its buildings span the 1836-1896 canal era and include canal-related structures and local limestone commercial buildings.

What listing means for this property
This is a historic district. Buildings within its boundary are either contributing (they add to the district's significance) or non-contributing. Owners of contributing income-producing buildings can claim the 20% federal rehabilitation tax credit; homeowners should look at state credits. National Register districts impose no design review by themselves; a local historic district ordinance, if one exists, does (the difference explained).
