$65 million clean up and rehabilitation of Echo Park Lake. The 12-inch thick wall made with 4,000-cubic yards of concrete and reinforced with steel rebar follows the contours of the lake, and, with the exception of a few breaks near the boathouse and bridge, will completely encircle the body of water.
“The new retaining wall will replace the old one that was falling
apart,” said Michelle Vargas. a spokeswoman with the Bureau of Public
Works. “ The wall will stabilize the lake edge, prevent erosion, create
easier maintenance of the lake, and act as a safety measure.”
Once the lake is refilled next year and paths rebuilt around the
water’s edge, only the top six inches to 12 inches of the concrete wall
will be visible.
