Kaanapali Beach has experienced chronic erosion and extreme seasonal erosion over the last 40 years, and sand loss is expected to continue and even accelerate with sea level rise.

HI - Comment Period Open for Kaanapali Beach Restoration and Berm Enhancement Draft EIS

KAANAPALI - The state Department of Land & Natural Resources is proposing a $9,275,000 project to replenish sand and mitigate chronic and extreme seasonal erosion at Kaanapali Beach over the last four decades.

The public has until Oct. 7, 2020, to submit comments on the Draft Environmental Impact Statement (DEIS) for the proposed Kaanapali Beach Restoration and Berm Enhancement.

A link to the study and details on how to submit comments are included in the Aug. 23 issue of "The Environmental Notice" posted on the state Office of Environmental Quality Control's website at health.hawaii.gov/oeqc.

According to DEIS documents prepared by Sea Engineering Inc., "The cumulative effect on the shoreline, the beach resource, and the sandy nearshore ecosystem has been negative. The State of Hawaii and the Ka'anapali Operators Association have developed a plan to ensure the long-term viability of this sandy coastal resource that includes both beach restoration and berm enhancement."

Beach restoration is proposed between Hanaka'o'o Beach Park and Hanaka'o'o Point (Hanaka'o'o Littoral Cell), and beach berm enhancement is proposed between Hanaka'o'o Point and Pu'u Keka'a (Ka'anapali Littoral Cell).

According to the DEIS, "The Hanaka'o'o Littoral Cell is suffering from chronic and episodic erosion, which has resulted in beach narrowing, beach migration, and damage to backshore infrastructure, including the Ka'anapali Beachwalk. The beach in this littoral cell is less seasonally dynamic than the beach in the Ka'anapali Littoral Cell to the north. The presently narrow beach, chronic erosion, and limited seasonal sand transport make this section of shoreline suitable for beach restoration."

Plans call for installing 50,000 cubic yards of sand to restore the beach to the approximate position shown in a 1988 aerial photograph. This would widen the dry beach by between 41 and 78 feet.

The Ka'anapali Littoral Cell experiences significant seasonal sediment transport between Hanaka'o'o Point and Pu'u Keka'a.
