A city built in canal and quarry eras
Joliet was platted in 1834 on the city's East Side, became the seat of newly formed Will County in 1836, and was renamed in 1845 for French explorer Louis Jolliet. The Illinois and Michigan Canal, excavated between 1836 and 1848, exposed dolomite bedrock that gave Joliet its 'Stone City' nickname and drove decades of quarrying. The East Side Historic District that grew up in that era today holds 290 buildings, 281 of them contributing, including 32 houses built between 1852 and 1873.
What that means for mold remediation today
That range of construction eras is the whole story for moisture work in the Joliet area. East Side homes built 1852-1873 have older framing, ventilation, and crawlspace conditions than the postwar subdivisions that built up Crest Hill after its 1960 incorporation and New Lenox after 1946, or the newer construction further out in Plainfield and Minooka. Add a Des Plaines River watershed where basement flooding and sewer backup are a documented regional concern, and a mold assessment has to account for the specific age and envelope of the house in front of it, not a single metro-wide assumption.
What official local sources add
The City of Joliet enacted a Stormwater Management Ordinance and is the permitting authority for land-disturbing and exterior work within city limits; the city's Community Development Department (150 W. Jefferson St., Joliet, IL 60432, (815) 724-4040) handles permits, and parts of Joliet sit within a mapped 100-year flood zone near the Des Plaines River. Will County separately maintains stormwater and water-resource ordinance chapters for unincorporated parts of the county. Confirm current exterior-work and permit requirements with the relevant authority before starting envelope or moisture-correction work.
