Honolulu officials said early estimates of damage from two March Kona-low storms exceeded $100 million, though the final cost could change as assessments continue and agencies seek federal reimbursement.
At a City Council Executive Management Committee meeting Wednesday, Chair Tommy Waters said 95,954 customers lost power during the first storm and 115,300 during the second. He said 236 people were rescued from floodwaters, 10 were hospitalized, and 72 people and two dogs were airlifted. Evacuation orders affected 5,500 residents in Waialua and Haleiwa, and 4,000 to 5,000 people faced possible risk from a dam failure, according to Waters.
Council members also questioned the city’s decision to place 2,700 tons of mixed waste at Patsy T. Mink Central Oahu Regional Park in Waipio after the March 23 storm. The city said 288 truckloads were taken to the temporary debris storage and reduction site.
Department of Environmental Services Director Roger Babcock said the site was opened the same day. “By 2 p.m., we had that site open,” Babcock told the Council. “We were working with the Department of Parks and Recreation to make that site possible.”
Babcock said contractors DRC Emergency Services LLC and Tetra Tech Inc. were activated to help, with Tetra Tech assigned to test for soil contamination. He said crews dug 3 to 5 inches at the site and removed about 1,000 cubic yards of material for federally required testing before disposal at Waimanalo Gulch Sanitary Landfill. If contamination is found, he said, excavation will continue in 3- to 6-inch increments until clean soil is reached.
Babcock said 50 post-closure soil samples had not yet been taken and that each testing round takes a little more than two weeks because samples are sent to the mainland. He estimated the contracted work will cost $4.5 million.
Asked why debris was not sent directly to the landfill, Babcock said the city did not know how much material it would receive and wanted a central site to sort recyclable items. “We don’t want to bury that if we don’t have to,” he said.
Budget Director Andy Kawano said the city’s latest estimate was $100.4 million, excluding a separate Board of Water Supply request. About $70 million involved capital projects and about $30 million affected the general fund, including emergency work. Overtime costs reached $2.5 million.
