An artificial reef offshore of 'Ewa at Kalaeloa has been proposed by the state Department of Land and Natural Resources, Division of Aquatic Resources.

The division has mapped out a 224-acre area nearly devoid of coral and valuable marine habitat. It has prepared a Draft Environmental Impact Statement for the project. That report also covers the first increment of artificial reef within the site boundaries.

It will incorporate at least two piles of Z-blocks totaling some 700 to 800 blocks that will be used to cover a seafloor area of about 8,000 square feet.

The public has until April 23 to comment.
