Ala Moana Reef and Beach Construction, Magic Island (aka ‘Āina Makua)

Honolulu, Hawai'i

Completed

1964

Magic Island, a man-made peninsula that is part of Ala Moana Beach Park, was a concept proposed by Belt Collins planners and implemented by its engineers. The intent was to develop the approximate 30-acre reclaimed shallow reef area as a resort, which did not come to fruition and the area was converted into a public park. In 1972 the State officially renamed the peninsula ‘Āina Moana, or “land [from the] sea”. It was turned over to the City and County of Honolulu and is still referred to by its original name amongst residents and visitors. Belt Collins also participating in landscape and engineering projects for refurbishment of the area.

Belt Collins provided detailed plans and specifications for the construction of Magic Island, a man-made peninsula consisting of 33 acres of beach park landfill and extending 2,400 linear feet from the shoreline. The work included the design for installation of approximately 3,200 linear feet of rubble seawalls and four rubble islands of varying lengths. Approximately 300,000 cy of fill material was imported and placed over an existing reef. Two artificial sand swimming beaches, of approximately 49,000 sy in total area, and 20,000 feet in length, were created. In addition, the project also included miscellaneous breakwater structures requiring 56,000 cy of armor stones of 2.5 tons to 200 lb. size, 2,580 cy of concrete and 15,730 cy of breakwater core material, and 81,000 cy of dredging.

Most recently, Belt Collins has been involved in refurbishment of the Magic Island park area, providing landscape design and coordinating a Level 2 Tree Risk Assessment for the parking lot repaving. The scope included replanting several large Monkeypod trees within the existing large planters, replacing nine smaller trees, and coordinating on Low Impact Development (LID) options related to parking lot storm water management. Belt Collins is also providing civil engineering services for replacement of the approximate 960-foot long walkway along the Magic Island Lagoon. Undermining of the wall on the lagoon side of the walkway has occurred, which will be repaired with the walkway replaced to provide safe passage and proper drainage into the lawn area.
