The cleanup of 40 or so homeless encampments on the slopes of Diamond Head State Monument will stretch into a third consecutive day today as a private contractor continues to break down the encampments and haul out tons of trash.

By Thursday afternoon workers from T&M Environmental had filled two 30-foot dumpsters and expected to finish up today, said Dan Dennison, spokesman for the state Department of Land and Natural Resources. Officers with DLNR’s Division of Conservation and Resource Enforcement led a pre-dawn sweep of the encampments Wednesday.

“It’s a big job,” Dennison said.

Seven homeless people were cited as the sweeps began, two of them agreed to go into homeless shelters Wednesday and another agreed Thursday, said Scott Morishige, the state’s homeless coordinator. Two others were referred to shelters, he said. Previously, two military veterans who had been living on the crater were placed in permanent housing.

T&M Environmental workers found 20 to 30 bicycle frames that had been stripped of parts, Dennison said. The frames were turned over to DOCARE officers.

Before Wednesday’s sweep a licensed operator with DLNR’s Division of State Parks surveyed the encampments with a drone, Dennison said. Starting next week the operator will continue to survey the area every week “to see if the camps are repopulated — or not,” he said.
