University of Chicago Land Surveys

Over the past four decades Chicago Guarantee has been doing work for, and around the University of Chicago. Recently we provided preliminary topographic information for the quad restoration project. After the plans were finalized Chicago Guarantee then supplied the layout necessary to bring the project to completion.

Here we see a survey done of lot one in block 3 in Ashland addition to Chicago, being a re subdivision of the overall Chicago subdivision. This survey seems to also require a vertical component in the Chicago City Vertical Datum system. I am sure I will cover more on CCD, or Chicago City Datum, in later posts as they arise.
