[1] Residents of densely populated cities, including Washington D.C., felt that the new technology was untested and steel-framed structures may suffer "serious and fatal defects" due to corrosion from steam pipes and electrical wiring – another relatively recent advancement.
In his report, Senator Curtis wrote that, "It would seem that the fire chiefs in the large cities who have had experience with high buildings are agreed that it is absolutely impossible for them to successfully fight flames over 85 feet (26 m) above the ground with the fire apparatus now manufactured, as the pressure is so great that no hose now made can stand the strain and the men are unable to handle the hose.
Structural corrosion and limitations of inadequate firefighting equipment are less of a concern today than at the turn of the century, and many major U.S. cities updated their zoning laws to reflect advancements in building technology.
[4] For example, the 1961 New York City zoning resolution used a Floor Area Ratio, rather than a height restriction, and allowed for taller buildings when an adjacent public space was provided on the site.
Yet, in Washington D.C. subsequent zoning laws followed the precedent set by the 1899 Act, and limited buildings to lower heights.
