Downers Grove sees a constant rhythm of renovation, additions and infill across its established neighborhoods and busy commercial corridors. A topographic survey turns the lay of a lot into precise contours and spot grades an engineer can actually design against. Getting that picture right up front is what keeps a foundation, patio or driveway draining the way it should.
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 Pi Surveying process — clear, sealed, and ready for your project.
Downers Grove is home to about 50,000 people and stretches across the Downers Grove, York, Milton and Lisle townships. It sits in DuPage County, whose seat is Wheaton and whose land records run through the DuPage County Recorder of Deeds. Salt Creek and tributaries of the East Branch DuPage River influence drainage and floodplain boundaries on parts of the village. Because many lots here carry gentle grade changes, a topo is often central to grading and drainage plans that keep water off finished basements during a rebuild or expansion.
Order one early, before design begins, so your architect and civil engineer have accurate elevations to plan foundations, grading and stormwater from the outset.
It records contour lines, spot elevations, existing improvements, visible utilities, notable trees and how surface water drains across the property.
It does not; the two answer different questions, and projects that touch setbacks or lot lines usually need boundary information alongside the topography.
