What a topographic survey shows

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.

When Wilmington projects need a topographic survey

New construction & additions — engineers need existing grades to design foundations and drainage
Site & civil design — grading, stormwater and utility plans start from topo data
Permitting — municipalities require topographic information for many site permits
Drainage & grading issues — document existing conditions before regrading

Wilmington & Will County specifics

Wilmington Township centers the city within Will County, with a portion reaching into Kankakee County, along the Kankakee River. Development and site improvements rely on contour and elevation data for grading and stormwater planning. Because the river corridor carries mapped flood hazard areas, topographic surveys here frequently support floodplain analysis. Land records for the Will County portion are filed with the Will County Recorder of Deeds. A CAD topographic survey provides Wilmington’s designers a precise model of the site’s grades and drainage.

What Wilmington-area clients say

I've used Pi Surveying a few times (once in the sale of my home and another in the purchase of my current home) and have to say I'm extremely satisfied with the service they provided. They were extremely detail oriented, experienced, and delivered an exceptional survey with very little effort on my part! From first call to job completion, they were always available and very communicative. Will definitely be calling them if I need them again!

This service is superb! I needed a survey done quickly. I had a deadline and I was out of options. Someone referred me to Pi Surveying and they were so easy to work with. They were competitively priced, quick to get the job done and reliable. Their customer service is top notch! I highly recommend!

Pi Surveying delivered exactly what we needed, on time and without any hassle. From the initial call to receiving our final survey documents, the process was smooth and straightforward. You can tell this team knows what they're doing — over 40 years of combined experience really shows in the quality and accuracy of their work. Highly recommend to anyone in the Chicagoland area!

We were very happy with the services provided by Pi Surveying. They came out quickly for a survey that I needed to get in order to put up a fence on our property. We were in a rush because the HOA would start fining us if we didn't get it done before the end of the month. They were awesome! Very highly recommend this company.

Pi Surveying helped me in the process of buying my commercial building. As a first time buyer, they were very helpful and efficient in taking care of the surveying part. My point of contact was very responsive and I would definitely recommend them and use them again. Great overall experience.

My wife and I were pleased with the Land Surveying services that Pi Surveying provided. The surveyor took the time to explain everything on the survey and what our property boundaries looked like legally. They were professional, courteous and efficient throughout the entire process. We highly recommend them!

Found myself in a bind after discovering some issues with a property. My real estate attorney pointed me towards Pi and I will do the same for anyone else! They were able to get me taken care of when I was in a time crunch, and didn't rake me over the coals with pricing. Standup company, honest, and have earned my business for life. Thanks guys!
