Construction crews in Honolulu are gearing up to tackle a vital infrastructure repair that's key to the city's flood control system. Starting tomorrow, the Department of Design and Construction will commence a significant project on the Keolu Stream Channel in Kailua, targeting a partially collapsed wall that has raised concerns about the area's resilience to severe weather. This effort forms part of a broader initiative to ensure that the stability of the channel walls and the surrounding slopes can withstand the trials inflicted by nature.

Residents should prepare for approximately 12 months of construction activity, a timeline contingent on the cooperation of the weather. The work schedules are set to run from Monday to Friday, starting at 8:30 a.m. and wrapping up at 3:30 p.m., steering clear of holidays to reduce disruptions. According to an announcement by the City and County of Honolulu, the team plans to effectively execute the project in phases, an approach designed to minimize to impact on local homeowners and the public.

Those in the vicinity of Keolu Drive and Kanapu‘u Drive will note the construction access via The Church of Jesus Christ of Latter-day Saints parking lot. Officials are urging the public to tread cautiously in the area, heeding all the warning signs, barriers, and directions provided by traffic control devices and personnel. For anyone seeking more information or wishing to express concerns, the City and County of Honolulu's Department of Design and Construction has made itself available at the contact number (808) 768-8400.

The specifics of the work include erecting a new 90-foot section of the channel wall, accompanied by backfilling and the installation of erosion control matting, which serves as a permanent best management practice. This reflects a commitment to not just repair, but to enhance the infrastructure's ability to manage the elements. In a statement obtained by the City and County of Honolulu, the project aims to "address a section of the channel wall that collapsed and improve the stability of the channel wall and the surrounding slope."
