The present benchmark, which is 364.159 feet above that datum, is located in the outer edge near the corner of the south pillar of the iron door-sill on the south side next to the southwest corner of the two-story brick building on the northeast corner of Third Street and Minnesota Avenue in the former City of Wyandotte.

All resolutions passed in pursuance of Ordinance No. 1215, entitled "An Ordinance Providing for the Establishment of the Uniform Datum Line in the City of Kansas City," approved January 22, 1890, reestablishing the grade of the streets in the territory of the former City of Wyandotte, Kansas, shall be made to read 313.479 feet above that datum line instead of 308.809 feet.

(h)

A point, indicated by a bronze tablet heretofore installed in the bridge over Jersey Creek on the Minnesota Avenue extension into the public levee, is designated as a benchmark for computations of elevations above sea level. The bronze tablet has been found by the United States Army Corps of Engineers to be 749.14 feet above mean sea level. The city engineer shall make such inscription on the bronze tablet as will identify the bronze tablet as such benchmark and shall make such records as will be proper and necessary to public authorities to use a reference to the benchmark.
