Video: Stormwater Project Continues at Garvanza Park

As on Highland Park-Mount Washington Patch, the Los Angeles Bureau of Sanitation and Northeast Tres are currently installing pair of cisterns beneath Garvanza Park in an effort to remediate the heavy flow of stormwater that typically flows through the park into the Arroyo Seco and on to the Los Angeles River.

This week, the cistern's components, referred to in the stormwater remediation industry as "pre-cast concrete modular stormwater management systems," were being installed in the belly of a giant pit that's been dredged in the park.

The components, which resemble massive concrete picnic tables, were moved into their proper places by crane on Tuesday afternoon. To onlookers, the process resembled a large-scale version of the classic video game Tetris.

Half of the concrete tables were laid on their tops along the bottom of the pit, while the second series of tables were set right-side down, so that the legs of each the tables's legs were touching, which caused them to form large, rectangular cells.

When completed, a concrete wall will be installed around the edge of the concrete matrix, which will allow it to effectively store the stormwater before it is remidiated through a layer of organic material that will lay beneath the cistern and back into the groundwater supply.

Once that water is remidated, it will be safe to drink again.
