In April 2008, the City of St. Louis and Gateway Foundation broke ground on Citygarden, and in just over a year, the two blocks between Eighth and Tenth Streets had been transformed from ordinary city blocks to the most extraordinary urban garden in the country.
While the transformation itself is remarkable, equally remarkable are the numbers behind that transformation. Here are a few of the more impressive Citygarden numbers:
Linear feet of water lines: 10,000
Linear feet of electrical conduit, mostly used for lighting and water feature control wiring: 23,000
Linear feet of sewer lines: 3,300
Linear feet of irrigation lines: 27,000
Linear feet of special drainage lines: 8,000
Vertical jets in the Spray Plaza: 102
Blocks of Missouri limestone, quarried in Perryville, in the Arc Wall: 1,200
Truckloads of rubble hauled from the build site: 400
Depth below street level excavated, in feet: 8
Weight of heaviest tree, a White Oak, imported into Citygarden, in pounds: 80,000
