Mauna Lahilahi Beach Park Erosion Mitigation Starts

Mauna Lahilahi Beach Park Erosion Mitigation Starts


A project to construct a new rock revetment and mitigate further erosion along the shoreline of Mauna Lahilahi Beach Park has begun.

The Mauna Lahilahi Beach Park Rock Revetment Project intends to: remove deteriorating sand bags from the previous erosion mitigation efforts, install a 330’ long rock revetment, and reconnect land access between both sides of the beach park.

This project’s coordination and permitting fully recognize, and taken into consideration, the archaeological significance of this site. The project-specific archaeological monitoring and water quality monitoring plans are in place and will be implemented by the general contractor’s specialty consultants.

Additional protective measures are being implemented, in collaboration with the State Historic Preservation Division, including the placement of 6” of gravel cushion on the access route and realigning the access route to avoid eroded areas. This realignment included the cutting of three coconut trees.

Work is scheduled to begin on the Mākaha-end of the shoreline and progress south.

The heavy machinery work is targeting to finish in fall 2020, with the landscaping maintenance period anticipated to complete by the end of 2020.

The approximately $1.72 million contract for this parks project was awarded to Kiewit Infrastructure West Co.

We ask the public to please be attentive and observe all construction warning signs and barricades, including during non-work hours. Mahalo for your patience and understanding.
