Joint Mānoa Stream Flood Mitigation begins Monday, Aug. 3

HONOLULU - The Hawai'i Department of Transportation (HDOT) announces the start of flood mitigation activities at Mānoa Stream beginning Monday, Aug. 3 near Woodlawn Drive. HDOT is coordinating the flood mitigations outside of its area of responsibility with the City and County of Honolulu Department of Facility Maintenance (DFM). Mitigation work will include removal of trees, rocks and brush along the streambed and existing walls, regrading slopes adjacent to the stream and dredging within the stream to reestablish the channel bottom.

Beginning Monday, Aug. 3 crews will work Monday through Friday from 7 a.m. to 5 p.m. to clear the streambed over a four-and-a-half-month schedule, weather permitting. Work will begin at the bottom section of the stream just below Woodlawn Drive and crews will work their way up the stream as work progresses. This initial section is estimated to take approximately two weeks to complete.

From mid-August through mid-October, crews will move upstream to continue work behind the Mānoa Marketplace McDonald's and nearby residences. Work will then move to the upper Mānoa Stream area near Kahaloa Drive and Mānoa Valley District Park, from mid-October to mid-December. These sections are estimated to take approximately two months in each work area.

Funding for the Mānoa Stream work and other stream mitigations will be provided through a $9.5 million allocation from the state's Major Disaster Fund as authorized by Governor Green and the state legislature.

Special duty police officers will be on-site to assist with traffic control and safety procedures. Electronic message boards will be posted to notify motorists of the planned closures. For questions on the mitigation work, residents are encouraged to contact DFM at 808-766-3343.
