Onarga is a small village in west-central Iroquois County, a historic farm and nursery community set in open prairie. Topographic surveys here support rural site design, residential projects and the grading and drainage planning that farmland and village lots require. Turning existing grades into CAD contours gives engineers a reliable base for design and permitting.
A topographic survey maps the elevations, contours and natural and man-made features of a site — grades, structures, utilities, trees and drainage — giving architects and engineers the data they need to design accurately and secure permits.

The village of Onarga, home to about 1,300 residents in Onarga Township, sits in the agricultural landscape of west-central Iroquois County. Runoff from area parcels drains toward the Iroquois River and its tributaries, so drainage and grading benefit from careful elevation mapping across the surrounding farmland. Land records for Onarga are recorded with the Iroquois County Recorder of Deeds in Watseka, the county seat. For new building projects, additions, rural sites or agricultural grading, a topographic survey documenting existing grades, structures and drainage gives the design team the accurate base needed for design and stormwater planning.
