Consent Calendar

Public Comments & Testimony
- Item 1 (Resolution 26-61): Erwin Kawata from the Board of Water Supply provided oral testimony in support of the appointment of Darien Chun. No other public testimony was offered.
- Item 2 (Integrated Plan): No public testimony was provided.
Discussion Items
- Appointment of Darien Chun to Board of Water Supply: Chair introduced a hand-carried CD1 (OCS 2026-0192, March 31, 2026) amending the resolution to correct the term expiration date, remove reference to replacing Brian Inouye's seat, and make technical amendments. Mr. Chun introduced himself, describing his background in construction and development (Kewit, Gentry Homes, Delta Construction, Royal Contracting, Castle & Cook) and his experience with water source and storage projects. He expressed support for affordable housing and for bringing back college graduates to Hawaii, noting about 20,000 people leave the islands annually. Committee members expressed appreciation for his expertise and commitment. The resolution was amended to CD1 and passed out of committee unanimously.
- Informational Briefing on Integrated Plan: Director Roger Babcock (Department of Environmental Services) presented the integrated planning framework, a EPA program to coordinate wastewater and stormwater compliance under Clean Water Act NPDS permits. He outlined six elements: understanding requirements, characterizing systems, connecting with stakeholders, developing alternatives, measuring outcomes, and adapting. Key drivers include maintaining affordable rates, meeting permit requirements, and addressing community priorities such as beach closures, urban runoff, flooding, and environmental justice. The city completed a feasibility study in 2024-2025 and is now conducting a full integrated planning study with stakeholder engagement (EPA, DOH, advisory group, public). Scheduled milestones: system characterization by summer 2026, prioritization by summer 2027, plan completion and acceptance by end of 2027, implementation starting 2028. Director Babcock noted challenges: wastewater sewer fees approaching EPA affordability criteria (2% of median household income), stormwater TMDL requirements (50% trash reduction by 2023, 100% by 2034), pending PFOS regulations, and costly injection well compliance for three treatment plants (Honouliuli, Kahuku, Waimanalo). He answered questions about Sand Island secondary treatment (on schedule for 2035), dieldrin at Kailua (estimated $750 million, target 2035, may be delayed), and cesspool pumping capacity (city pumps cesspools at low fee, private haulers provide most service). Regarding recent flood events, Director Babcock noted stormwater management intersects with water quality but emergency pumping (ponding) is handled by DFM, not ENV. The integrated plan will focus on regulated water quality issues rather than disaster preparedness.
Key Outcomes
- Resolution 26-61 (Appointment of Darien Chun): Unanimously passed out of committee as amended (CD1) with no objections or reservations. It will proceed to full council for adoption.
- Integrated Plan Briefing: Received by committee. No formal action taken. Director Babcock emphasized the need for council support to prioritize projects and manage costs amid increasing regulatory requirements. The next public meeting is planned for fall 2026.

Now, members, we want to welcome uh Mr. Chan, the appointee up to the podium to do an introduction. If you want to just state your name, push the button, just make sure the red light is on for the speaker. And I'll just open up with maybe if you could share a little bit about your background and what that brings to your service, and also you know, things you want to maybe look at or work on. Thank you. Um hi, my name is Darien Chun. I'm as uh councilman wire said. I my first uh employment was with Kewit, and after I worked with Kewitt, I worked for Gentry Homes, and then I went to work for Delta Construction, and after that, then royal contracting, and then I went back to work for Castle and Cook. And after that, I went back to Royal Home Royal Contracting where I'm at currently. As you can see, my background has been both on the development and also on the contractor side. Uh when I was at Cast and Cook, I was a director of site development, and so we're currently building, or when I was there, we're working on and building, and they're currently building a water source and storage for the Core Ridge development and other future developments. So I do have some knowledge about uh that type of system that the Board of Water Supply is working on. I worked with Irwin on a couple of things, and so um I hope that I could bring my knowledge of construction and also development to that to the board because I'm always looking for uh ways to help the community and also to make our island and our residents able to afford homes and make it more cost effective for them. Um I'm also on a couple of uh legislative committees, the GCA and NIOP, and therefore I'll try to look help with the bills to make it more cost effective and affordable for our residents and homeowners and even our college graduates to come back home and work here. Uh we there's a there's been a lot of people that have left the islands. I know there's about 20,000 people a year that's been leaving the islands to work on the mainland, and if we can get that brain power to come back and live in Hawaii, we can make Hawaii a better place to live. And so that's why I'm always here trying to find the way to make it more cost effective and affordable for everyone to live here. Um right now I I hope I can give my experience to help the board out and find future sources in the in the future. Thank you. Mahalo appreciate that. Any questions from the committee members at this time? Um seeing none. Councilman Ratova. I just wanted to say I appreciate uh Mr. Chan's time uh on Zoom. I I appreciate the you know the wealth of knowledge you'll bring to this commission and hopefully, you know, all things he's saying about affordable, you know, and making sure that uh some of our young minds that went away come back so that you know we can again, like you said, I'm just echoing everything they say. It's so important for us to have them come back and uh live in a place that you know we all grew up and hopefully you know we'll end our last days at, you know. So appreciate you coming by and I appreciate you um you know giving yourself up to be a part of this commission. Thank you. Appreciate that. Mahalo echo those sentiments.
