HONOLULU - Happening Wednesday night Palolo residents will have a chance to voice their concerns over a controversial flood mitigation project. 

It's called the Ala Wai Flood Risk Management Project. Not only would it impact residents in Palolo, but also in Manoa and Makiki Valleys. 

The $345 million project is on the agenda at Wednesday night's neighborhood board meeting in Palolo.

The U.S. Army Corps of Engineers wants to build six debris and detention basins up stream in those valleys. The idea is to have those basins catch debris, which would prevent it from washing into the Ala Wai -- therefore preventing a flood in Waikiki. In order to do that, at least 27 properties would be impacted.

The plan was recently discussed at the Manoa neighborhood board meeting, where several hundred people gave emotional testimony against the project. And it'll be up for discussion again at the Palolo neighborhood board meeting Wednesday night. 

It will be held in the elementary school cafeteria at 7 p.m.
