2. The proximity of the project to the partially enclosed
Pillar Point Harbor and the potential for tsunami events could
expose people to inundation by seiche, which represents a
potentially significant impact. Big Wave Project DEIR IV.H

5. A seiche (pronounced /se/ "saysh") is a standing wave in an
enclosed or partially enclosed body of water.
6. Hilo Bay Seiche April 1st 1946 The tsunami that hit Hawaii
in 1946 had a fifteen- minute interval between wave fronts. The
natural resonant period of Hilo Bay is about thirty minutes. That
meant that every second wave was in phase with the 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/seiche
reaching a height of 26 feet along the Hilo Bayfront, killing 96
people in the city alone. Seiche waves may continue for several
days after a tsunami.

13. Structures should either be placed at elevations above
those likely to be adversely affected during a tsunami or seiche
event or be designed to allow swift water to flow around, through,
or underneath without causing collapse. Big Wave Project DEIR IV.H
Hydrology & Water Quality Page IV.H-61
14. ABAG tsunami maps show that the project would place
residential and commercial structures within a mapped tsunami
zone.
15. Emergency Evacuation Would you want to be trapped with
swirling water and debris all around you? Would you want to
desperately try and escape a natural disaster with traffic from the
office park choking your exit? How do special needs people get the
necessary evacuation help needed?
16. Grand Jury Report The San Gregorio fault, just off the San
Mateo County Coast, has the potential of causing a tsunami with
essentially no warning time. The San Mateo County Office of
Emergency Services (OES) advises that members of the public who are
in low- lying areas immediately head for high ground when an
earthquake occurs. Grand Jury Report: 2007 Tsunami Alert and
Evacuation San Mateo County Coast
17. Princeton, Pillar Ridge & Seal Cove only have ONE
Tsunami Evacuation Exit

20. Earthquake and Tsunami Evacuation ALL TRAFFIC in PRINCETON,
PILLAR RIDGE and SEAL COVE MUST USE CYPRESS AVE as the SOLE
EVACUATION ROUTE ONTO HIGHWAY 1
21. Cypress Ave and Highway 1 is a Traffic Bottleneck How will
residents, visitors and employees evacuate Princeton, Pillar Ridge,
Seal Cove, the proposed Big Wave office park and sanitarium in the
event of an earthquake or tsunami emergency? How will the current
emergency evacuation route, ONE exit onto Highway 1 and NO traffic
light at Cypress and Highway 1 be adequate in the event of an
earthquake or tsunami emergency?
22. Emergency Evacuation Route Cypress Ave and Highway 1 A
traffic signal currently needed at this intersection.
