Hi Paul,
The IRT reviewed the Riverbend Crediting Adjustment Memo and would offer the following
comments:
1. Please provide a lidar map in the draft mitigation plan to help justify the stream alignment of
UT2.
2. The stream relocation will likely impact existing wetlands; account for this in the permit
application.
3. Please ensure that no wetland credits overlap with the newly relocated stream channel.
4. Please make sure that you have sufficient wetland gauge coverage of all areas, including the
enhancement areas where you are proposing ditch and stream work will help improve
wetland function.
5. We request the placement of a stream flow gauge where restoration transitions from an
ephemeral ditch to a perennial stream.
6. Please provide justification why the confluence of UT2 and UT to SF was shifted downstream

from the original proposal. Are there any concerns with parallel channels within a generally
flat area?
7. Please provide some discussion why the stream design changed so much due to the UT2 JD.
Please reach out with any questions.
Thanks,
Kim

Subject: [URL Verdict: Neutral][Non-DoD Source] IRT Review Request: Additional Information &
Crediting Adjustment Memo - Riverbend (DMS#100592) - (SAW-2021-02608) (DWR#2021-1629 v1) -

Casey, Erin, Kim and Todd;
During the IRT post -contract site visit for the Riverbend Mitigation Site on March 8, 2022, the IRT
requested that WEI provide additional data to better understand the historic condition of the
wetlands on site. WEI has completed additional stream and wetland delineation work on the site
and have compiled this memo for IRT review. This additional information was used to revise the
proposed credit and mitigation approaches. Proposed changes, an updated asset table, updated
maps/figures and a detailed hydric soils report are included with the memo.
Please review the memo and let us know if you have any questions, comments or concerns.
Wildlands will utilize this additional information and any IRT feedback in the development of the
project's mitigation plan (for IRT review).
