Owen Farms Stream and Wetland Mitigation Site

Contract No. 7532
SAW-2018-01165
To Whom It May Concern,
As per your email dated June 29, 2021, we have reviewed and addressed the NCIRT's review comments
as follows:
Erin Davis, DWR
DWR is ok with the planted vegetation species/quantity substitutions. Were there any species
changes in the previously approved site seed mixes?
RE: There were no changes to the previously approved site seed mixes.
2. DWR appreciates the inclusion of aerial photos. These images are helpful for agency review.
RE: Understood.
3. During the IRT construction site walk following significant a storm event in November 2020, we
observed areas of floodplain scour and major movement of stone from original bed/bank
placement. Was there any adjustment of floodplain width and/or slope from the original design?
And was there any adjustment is rock size for riffles and/or bank toe structures?
RE: Following the significant storm event in November 2020, the floodplain was widened on the
right side of WFFB between STA 10+00 and STA 14+00, and along the left overbank area
between STA 16+50 and STA 19+00. The floodplain was widened to relieve shear stress along
the bench and the cut material was utilized to repair the eroded channel banks and floodplain
scour. Revised redline plansheets have been attached as part the response to comments
indicating the locations of where the floodplain bench was extended.
There were no adjustments to slope, riffle particle size, or bank toe structures from the original
design except for what was called out in the report and the redline plansheets.
Casey Haywood, USACE
1. No issues with the changes to the species type and composition for the planted vegetation.
Appreciate the effort in identifying the planting zones.

2. The report mentions Bog complex communities being planted with high percentages of shrub
species; I understand that these are not expected to reach the height requirement/vigor
standard, but I was wondering how success and/or survival is being monitored in these areas?
RE. LMG will continue to monitor these areas for planted stem density as an indicator of overall
survival and health. As noted in the approved Mitigation Plan, Bog complex communities are
not expected to reach the height requirement of other "tree dominated" communities open
patches dominated by herbaceous species within the bog complex is typical for the community
type.
3. 1 did not see UT1, UT2, or UT3 in the Table 6 Project Attribute table. Why were these left out of
the table?
RE: An updated Table 6 Project Attribute Table has been attached with this submittal.
4. Given the amount of damage seen during the November site visit due to major storms, I also
think it would be beneficial to schedule a site visit for next year.
RE: Understood.
If you have any questions or need additional information, please do not hesitate to give me a call
(843.830.1536).
Sincerely,

Good afternoon,
The 15-Day Record Drawing review for the Owen Farms Mitigation Site (SAW-2018-01165) ended
June 25, 2021. Per Section 332.8(o)(9) of the 2008 Mitigation Rule, this review followed the
streamlined review process. All comments received from the NCIRT are incorporated in the attached
Memo. Please address IRT concerns in a response to comments, addressed to USACE. There were no
objections to issuing the initial credit release. Please find attached the current signed ledger. The IRT
would like to visit this site next year after monitoring for year 1 is complete.
