Storm Drain Report – Niu Valley & Aina Haina

Last Thursday I had the privilege of presenting a Storm Drain Report to Kuliouou-Kalani Iki Neighborhood Board members and residents. The report has also been given to city representatives.

One of my main concerns was the way the roadways had been repaved in Aina Haina. Specifically, gutters were paved over, and access to storm drains has been reduced. According to a resident, she had checked with the city several years ago when crews were working and was told the repaving project was designed that way.

At a minimum, the standard that allows repaving to be done in this manner should be looked at, and unless there is a very good reason for almost blocking off access to storm drains, the practice should be disallowed.

Here’s an example of a drain that has been almost blocked off. This one is near Diamond Head. I will post a report about Kahala storm drains next week.

Diamon Head almost closed 7-1-18

  1. Your efforts to conduct this survey and install the placards are commendable, however, there is one key observation missing. Had this been any city on the mainland you would have encountered numerous devices installed in the storm drain system designed either to prevent trash from entering the drains or capture trash and pollutants before they are flushed out onto the reef. The City of Honolulu needs to rise to the challenge and install pollution prevention devices in the storm drain system.


    1. Thank you for your comment. It will be included in our report on Kahala and Diamond Head, to be released at the Waialae-Kahala Neighborhood Board meeting today.
