HomeServicesTopographical Land Surveys › Streator, IL

Streator is a former industrial and glass-making city straddling the LaSalle and Livingston county line along the Vermilion River. Topographic surveys support redevelopment of older commercial and industrial sites here, along with the grading and drainage planning that comes with reworking established parcels. Contour and elevation mapping turned into CAD gives engineers a reliable starting point for design and permitting.

Streator & LaSalle County specifics

Streator, a city of around 12,500, sits mainly in Bruce Township in southern LaSalle County, with part of the community reaching into Reading Township in Livingston County. The Vermilion River runs through the area and feeds toward the Illinois River system that drains the county, so grading and stormwater planning on many sites has to consider how runoff reaches those corridors. For parcels on the LaSalle County side, deeds and plats are recorded with the LaSalle County Recorder of Deeds in Ottawa. A topographic survey documenting existing grades, structures and drainage is frequently the foundation for redevelopment, additions and civil design across the city’s older neighborhoods and commercial blocks.
