More about Lindsborg's Elevation

I'm still on the trail of the elusive definitive answer to the question, "Who determined the elevation of Lindsborg, and how."

I got a step closer today when I visited with Mr. Dunn in the city's Public Works office.

He assured me that there is no "city datum" for Lindsborg, which confirms what I suspected to be the case. He then showed me a list of "benchmarks" throughout the city, spots whose elevation has been precisely determined and which can therefore be referred to in other drawings and building plans where elevation would matter (laying sewer pipe, for example).

Below is the "highest point" in the city, actually the highest benchmark, at 1336 ft and change.



Notice how elevated Kris looks standing at that point.



The spot is located on the N.E. corner of Lindsborg and Chestnut Streets.
According to Mr. Dunn, it's all downhill from there.

The lowest benchmark is at 100 Normal, at 1322 ft. In general the land slopes from south to north, which makes the flow of the creek kind of interesting, since it generally flowed in the direction of the Smoky Hill River, back in the day when the creek that ran through town was an actual creek.

I have half my answer. Now the question is, who and how was 1331 ft. determined to be the elevation for the train depots?
