From Ink Lake:
This past summer and autumn, volunteers under the aegis of the city Parks and Recreation Department, removed the vegetation that had sprouted (and was cracking the tiles apart). A layer of sand was then placed over the floor, and then a geotextile was placed on top, finally covered by a layer of gravel.
The city has applied to the state for an Environmental Protection Fund grant to conduct studies of the condition of the towers and other structures. If the funding is obtained, based on the results of those examinations, next steps can be decided.
At least things aren’t getting any worse.
Well, if the soon-to-be-ex-governor's cuts to the EPF stand, then it's not likely the funding will be obtained. The loss of the EPF fund is threatening zoos, botanical gardens and aquaria as well as proposed park projects.
