<strong>Meeting</strong> <strong>Notes</strong><br />
Doug Kenley (PND)<br />
Anther option is to have an elevated structure all the way along the roadway. There is little<br />
tidel<strong>and</strong> footprint. This option would cost of $160 million. It is eight times more expensive<br />
than the 2.1 slope option.<br />
Skip Joy (COE)<br />
If it access is through the military base, then none of these options are pertinent.<br />
Robin Reich (HDR)<br />
This is true however, the below the bluff alignment will be one of the alternatives in the Draft<br />
EIS. Do you have input now? You can also call or email us.<br />
Skip Joy (COE)<br />
I think you could drop the spur dike option.<br />
Heather Dean (EPA)<br />
I agree.<br />
Skip Joy (COE)<br />
The Corps would like the longest bridge possible.<br />
Heather Dean (EPA)<br />
The decision on embankments <strong>and</strong> abutments should be based on fisheries <strong>and</strong> beluga studies.<br />
Skip Joy (COE)<br />
Modeling <strong>and</strong> velocity is going to play into the decision. Friction is an important factor.<br />
Financially, less fill is better, but we like to see the smallest footprint too. Current velocities<br />
have impacts.<br />
Robin Reich (HDR)<br />
We heard the smallest footprint is desirable from USFWS, NOAA Fisheries, <strong>and</strong> ADNR<br />
OHMP. I believe they also preferred the 2.1 roadway sideslope.<br />
Skip Joy (COE)<br />
That’s my first leaning as well, as long as it doesn’t create high velocities. I really don’t see<br />
that happening here.<br />
Heather Dean (EPA)<br />
I would defer to the (agencies concerned with) fisheries on determining the best design.<br />
