HANALEI — The blue color surrounding the construction at Hanalei Pier and Black Pot Beach Park area is hydro-mulch, put on the ground to grow grass, according to county officials.
“The blue color you see is non-toxic, biodegradable dye used to identify the hydro-mulch,” according to the county. “Additionally, silt fences were used as a partition between the application of the hydro-mulch and the beach area.”
It’s part of the rebuild of Weke Road and Black Pot Beach Park that were washed out during April floods, and then again in some places in August.
The project, expected to cost at least $1 million, could be completed by late 2019.
Some residents asked questions about the blue residue Monday.
