Bryan and Alan,
We suggest the following to prevent the existing wetland from shrinking-
- We will construct the profile to maintain the wetlands upstream by setting instream structures to keep area
wetlands.
- Basically the in -stream structure acts as a weir and keeps that portion of the old pond as wetlands.
- Additionally, we will create more wetlands along the bankfull bench and floodplain area by grading micro
pools below the groundwater level.
Let me know if you have any other questions or comments and if you need to visit the site after the pond has
been drained (pond draining and conceptual restoration plan included as Attachment E). The final location for
the stream will be determined after the pond has been drained and the stream construction within the pond
footprint and planting work would likely occur in late fall.
Thanks,
Aliisa

Ms. Harjuniemi,
The PCN submitted for 912 W Rocky River proposed to drainage an approximate 1 acre pond and restore a
pre-existing stream channel through natural stream design. However, abutting the pond and stream channel
downstream of the pond is Wetland AA. This wetland is likely hydrologically connected/supported Pond A
and without that pond in place in the future there is a likelihood that wetland at least shrinks if not completely
disappears. Your PCN did not mention or account for this in anyway and the Corps cannot move forward with
issuing the NWPs until it is certain that additional loss of wetlands do not result from draining the pond.
