Pedestrian Safety Enhancements Slated for Ali‘i Drive at Keauhou Shopping Center Sept. 10 

In an effort to improve pedestrian safety at the intersection of Ali‘i Drive and the entrance to Keauhou Shopping Center, the County of Hawai‘i Department of Public Works Traffic Division will be adjusting the intersection’s traffic signal light timing and phasing on Tuesday, September 10, 2019 from 8:00 a.m. to 2 p.m., weather permitting.

As a result of the enhancements, pedestrians will be able to use the crosswalk on the makai side of Ali‘i Drive unimpeded by traffic during which time motorists will have a red light. 

All drivers and pedestrians are reminded to be mindful of the surroundings and situation and to proceed cautiously. A special duty officer will be on hand for traffic control while the pedestrian timing enhancements are being completed.

The County of Hawai‘i Department of Public Works apologizes for any inconvenience this may cause and thanks the community for their patience and understanding.

If there are any questions or concerns, please call the Traffic Division at 961-8341.


US Army Corps of Engineers to Provide Update on Waiākea-Palai Flood Mitigation Project at Sept. 12 Community Meeting

The US Army Corps of Engineers will provide an update on the Waiākea-Palai Stream Flood Control Study at a community meeting on Thursday, September 12, 2019, from 6:00 p.m. to 8:00 p.m. at the Hilo Municipal Golf Course (Multipurpose Room), 340 Haihai St. in Hilo.

Earlier this year, the US Army Corps of Engineers and Hawai‘i County Department of Public Works Engineering Division held a series of meetings seeking community input on different proposed measures to reduce flood impacts involving Waiākea and Palai Stream areas. Now that the public review period is over, officials will provide an update on the feedback they received and final recommendations.

At the September 12 meeting, US Army Corps of Engineers staff will also provide an updated timeline to complete the processes mandated by the National Environmental Policy Act and the feasibility report. They will be taking questions and explain the next steps of the design phase and implementation. It’s estimated that design and review of the recommended measures will take about a year followed by a year of construction.

Neighborhoods within close proximity of the Waiākea Stream, Palai Stream, and Four Mile Creek are encouraged to attend.  

If there are any questions or concerns, please call Bryce Harada of the Engineering Division, (808) 961-8042.
