Amy,
The bridge deck drainage pipe drains into a proposed roadway ditch with 4:1 front
slopes and 3:1 back slopes that runs parallel to the roadway and will be graded to
drain into the wetlands southeast of the bridge. We will adjust the rip rap pad so
it is in line with the roadway ditch. Right now it looks like it is draining into
the buffer but it is not.
Our bridge report design calls for no deck drains on the bridge.
Keith,

Please verify that the bridge design calls for no deck drains on the bridge.
Let me know if you have any questions or need anything else

Hi Andrew,
I just had a call from Garcy Ward at DWQ regarding the permit application for B-
4533, specifically the stormwater management plan. DWQ has two concerns:
1) The bridge deck drainage pipe that releases into buffer zone 2--while DWQ doesn't
object to this IF the water drains away from Wheat Swamp Creek, Garcy was not
convinced the water would drain away given current conditions on the ground (he
visited the site). He said no grass swale exists now, and unless some grading was
done he wasn't sure the water wouldn't find its way back to the creek. Do you know
how this drainage will be accomplished more specifically?
and
2) No deck drains--Garcy just wanted to make sure there weren't going to be deck
drains over the buffer, which he has seen before (even when it was stated that the
bridge would have no deck drains).
Thanks for looking into this,
Amy
