The tsunami that hit Hawaii in 1946 had a fifteen-minute interval between wave fronts. The naturalresonant period of Hilo Bay is about thirty minutes.

That meant that every second wave was in phase withthe motion of Hilo Bay, creating a seiche in the bay.

As a result, Hilo suffered worse damage than any

other place in Hawaii, with the tsunami/seichereaching a height of 26 feet along the Hilo Bayfront,

killing 96 people in the city alone. Seiche wavesmay continue for several days after a tsunami.

Structures should either be placedat elevations above those likely to be

adversely affected during a tsunami

or seiche event or be designed toallow swift water to flow around,through, or underneath without

causing collapse.

ABAG tsunami maps show that the projectwould place residential and commercial

structures within a mapped tsunami zone.

This would represent a significant riskto human life.

The San Gregorio fault, just off the SanMateo County Coast, has the potential ofcausing a tsunami with essentially

no warning time.

The San Mateo County Office ofEmergency Services (OES) advises thatmembers of the public who are in low-

lying areas immediately head for highground when an earthquake occurs.

On Nov 4th 2009 it was brought to the Countiesattention that agencies and the public wereprovided an incomplete printed draft EIR.

One week later on Nov 11th 2009 the missingsection N. was delivered via FedEx to agenciesand the Half Moon Bay Library.

Why didnt the County restart the 60 day CEQAreview period on Nov 11th after the incompletedraft EIR had been supplemented with the 63 pagemissing chapter N. Utilities and Service Systems?
