Let’s continue looking at area sidewalk marking requirements. Today I found East Lansing’s requirements for sidewalk construction, and I am happy to report that it contains this:

The contractor must stamp the concrete with the contractor name and current year at the limits of the pour, using a professionally manufactured/fabricated stamp ONLY. No other methods will be allowed.

This is the first one I’ve found that is particular about the nature of the stamp. Apparently East Lansing didn’t want any of these kinds of shenanigans.
