Doug,
The project engineers have looked into addressing your comments and they were able to elevate one of the
culverts for the double-barrelled crossing to have one taking the base flow with the other one raised, as the double is
being used to handle storm flow. Also, they have reduced the culvert sizes in the other crossings to the minimum
possible width while meeting flow/volume requirements.
I have attached updated exhibits here to reflect these changes, please let me know if this satisfactorily
addresses your concerns.
Thanks,
Daniel

Hey Daniel,
I had some questions on this one. It is mainly about the culverts and the sizes proposed. It looks like all of the
culverts are proposed to be 72", which should be fine for Stream V, however for the other stream crossings, that
seems way too big for the average sized streams of 4', 3', and 2' respectively. I'm concerned they'll be over widening
the streams which would result in a loss of waters and thus more impacts. Also, why is a double -barrel 72" proposed
for Stream V? If it's to handle storm flow, then one of those barrels should be higher in elevation than the main
barrel to accommodate that flow. If you could get back to me on this one, that would be great.
