When discussing the mosaic panels once at 7th and Figueroa, I thought of this image, of the Grasscrete parking surface once used at this location. (It also confirms the mosaic’s placement at that site, before removal.) A colleague at the L.A. Conservancy said this was her strongest memory of visiting this branch in the 1970s and 1980s.
As the caption from this 1977 calendar proclaims, “combining real grass with concrete patterns that support the weight of cars, GrassCrete brings much-needed green belts to the central city.”
GrassCrete seems to be the brainchild of the Bomanite corporation, one of their ways to create “ornamented concrete.” Boman was an artist turned industrial contractor — clearly, a career path Millard Sheets would have admired.
The number of marketers and technical papers online suggest it is still possible to order and install GrassCrete, which I have encountered, here and there, in public plazas.
One wonders why (cost? impracticalities? mud?) this simple way of greening parking lots and sidewalks did not catch on.
