Suzan,
Based on the information I have, the top of the 4 - 5' x 10' box culverts will sit at 508.34 over the 12" PVC
sanitary sewer line. I've summarized my figures below:
· Flow line of 12" PVC sanitary sewer line at approx. 500
· Top of 12" PVC sanitary sewer line at approx 501
· 1' of clearance puts bottom of box culvert at 502
· Top of box culvert then sits at 508.34 (bottom box thickness of 0.67', plus 5' box opening, plus top box
thickness of 0.67')
The 1' of clearance will allow room to encase the line with 6" of concrete and still have 6" clearance below the
box culverts. I believe F&N preferred that the top of the box culvert not exceed 507.68, based on an earlier e-
mail (around May 2004), but could make some changes that would allow the box culverts to be raised 1.30 feet
to 508.98. Please call if you have any questions or comments. Thanks.
Craig

Craig:
Freese and Nichols is anxious to see the culvert design for the box culvert under Bethel Road to make
sure their roadway design is still working okay. Even if we do not construct the gabion channel - the
design of the box culvert under Bethel will need to be finalized so that F&N can proceed. In our meeting
with the Corps, I explained to them that there was an existing sewer line in the roadway that could not
be lowered or relocated. I also told them that we could not lower the interior boxes to allow for the pilot
channel flow - and that we were limited in what we could build.
Thanks
