Early Notice and Public Review of a Proposed Activity in a 100-Year Floodplain
Community Development Block Grant (CDBG)

To: All Interested Agencies, Groups, and Individuals

This is to give notice that the City and County of Honolulu (City) under Part 58 has determined that the following proposed action under the Community Development Block Grant (CDBG) program and B-18-MC-15-0001 is located in the 100-year floodplain and the wetland, and the City will be identifying and evaluating practicable alternatives to locating the action in the floodplain and the wetland, and the potential impacts on the floodplain and the wetland from the proposed action, as required by Executive Order 11988 and 11990, in accordance with HUD regulations at 24 CFR 55.20 Subpart C Procedures for Making Determinations on Floodplain Management and Protection of Wetlands.

The City intends to utilize $2,622,000 in CDBG funds to construct a recycled water (R-1) waterline and associated connections to upgrade existing irrigation water service to the ‘Ewa Villages community. The project is located at TMK: 9-1-016:142, 9-1-017:103,111,112 and 113; 9-1-095:163; 9-1-097:103; 9-1-126:110 and Renton Road right-of-way between Kihi Street and Park Row. In addition, two possible staging areas have been identified at TMK 9-1-126:003 and 9-1-126:014.

A new connection to an existing 16-inch R-1 main at the west end of Renton Road and the new 12-inch and 18-inch waterline will run for a length of approximately .75 miles along Renton Road between the Ka Makana Ali’i Shopping Center and Park Row. The new waterline will provide a direct connection to the Board of Water Supply’s R-1 distribution system and allow the ‘Ewa Villages community to receive high quality R-1 water directly from the Honouliuli Wastewater Recycling Facility (HWRF).

The project crosses 10 separate parcels with an approximately 376 combined acreage. The central portion of the project surrounding Kalo’i Gulch (east of Kapolei Parkway) is located within the 100-year floodplain (Zones AE and AEF) and a wetland. The Base Flood Elevation has been determined and identified on the Federal Insurance Rate Map (FIRM), Panel 15003C0310G, effective January 19, 2011. The proposed waterline will be structurally mounted to the bridge, which is located above the base flood elevation of 36 feet at this location.

There are three primary purposes of this notice. First, people who may be affected by activities in floodplains and those who have an interest in the protection of the natural environment should be given an opportunity to express their concerns and provide information about these areas. Commenters are encouraged to offer alternative sites outside of the floodplain, alternative methods to serve the same project purpose, and methods to minimize and mitigate impacts. Second, an adequate public notice program can be an important public educational tool. The dissemination of information and request for public comment about floodplains can facilitate and enhance Federal efforts to reduce the risks and impacts associated with the occupancy and modification of these special areas. Third, as a matter of fairness, when the Federal government determines it will participate in actions taking place in floodplains, it must inform those who may be put at greater or continued risk.

Written comments must be received by the City at the following address on or before October 31, 2019: City and County of Honolulu, Department of Budget and Fiscal Services, 530 South King Street, Room, 208, Honolulu, Hawaii 96813, and (808) 768-3931, Attention: Nelson H. Koyanagi, Jr., Director. Comments may also be submitted via email at

A full description of the project may be reviewed between the hours of 7:45 a.m. and 4:30 p.m., Monday through Friday at 925 Dillingham Boulevard, Room 240, Honolulu, Hawaii 96817 and at site-bfs-sitearticles/408-federal-grants.html.
