The
University of Hawaii SOEST program has provided very extensive details, 3D
graphics and animations showing how vulnerable Honolulu low lands are to
flooding from sea level rise,
hurricane storm surge and tsunamis. Updated new City tsunami
maps all show a much greater inland evacuation area than previous maps.

All City, State and Federal data ALL
SHOW that building new Federally funded infrastructure in extremely low areas
is a MAJOR RISK and alternatives need to be planned as soon as possible.
The
Honolulu project study illustrates the effect of three feet of sea-level
rise on the coastal inundation zones (hurricane and tsunami) and showed
that 80 percent of the area’s economy, nearly half of the population, and
much of the infrastructure and land area at risk of coastal inundation.
US DOT Flood Zones
Protection of floodplains and floodways is required by Presidential Executive Order 11988, US DOT Order 5650.2, the Federal Aid Highway Program Manual (FHWA 1992b); and 23 CFR 650
(CFR 1999). These regulations place special importance on floodplains and floodways and require Federal agencies to avoid conducting, allowing, or supporting actions on a floodplain or within a floodway. If a project is located within a floodplain or floodway, results from sufficient analysis must be included in the project’s Final EIS, as specified in USDOT Order 5650.2.

"Floodplain Management," places special importance on floodplains and directs federal agencies to avoid conducting, allowing or supporting actions on a floodplain. When contemplating a mass transportation project, maps of the Federal Insurance Administration should be consulted to determine if the proposed project site is located within the 100-year floodplain.

Significant floodplain encroachment
would involve one or more of the following impacts:
- A considerable probability of loss of human life;
- Likely future damage associated with the encroachment that could be
- substantial in cost or extent, including interruption of service on or loss
- of a vital transportation facility: and
- A notable adverse impact on natural and beneficial floodplain values.
In
Mapunapuna small fish including baby Hammerhead sharks have been seen coming up
through the storm drains which are directly connected to the ocean.
The Environmental Impact Statement (EIS) document must identify why the Proposed Action is the only practicable alternative, and provide supporting documentation reflecting the
consideration of alternatives to avoid or reduce adverse impacts on the floodplain.
THE WHITE HOUSE
January 30, 2015.
On January 30th, President Obama issued
Executive Order (EO) 13690 that revises Executive Order 11988 and proposes a
new Federal Flood Risk Management Standard (FFRMS).
