    Blue hydro-mulch is being used to grow grass along Hanalei Pier.

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.

    HYDROMULCH is a SUPER FERTILIZER. While it is biodegradable it is not fit for marine environments as it is a fertilizer and contains high amounts of NITROGEN. Nitrogen from farm runoff is the main culprit along with climate change killing our reefs. Not good for Hanalei bay reefs, corals etc. If a city decides to use hydromulch to control erosion that is an issue that should go to the city council and they need to be transparent to the community about using these types of materials. The last thing we need is more chems running off into Hanalei bay or any reef systems on Kauai. KAUAI GOVERNMENT LET THE COMMUNITY KNOW WHAT YOU ARE DOING ! BE TRANSPARENT. YOU WORK FOR US, NOT AGAINST US!
