Byron,
After our discussions, the information that has been provided, and a review of our files, I
agree that there are ample mitigation credits to cover the deficit far this project. The DWQ
agrees that the NCDOT can cease monitoring of the site and request close out. Should you have
any further questions, please let me know. Thank you.

Subject: U-92 mitigation (3rd Street)
Hello all,
Westphal, Anneliese; Wilson, Travis
I've attached the information we discussed about U-92 mitigation last week. The first part
is what I passed out in the field (with one correction concerning cypress gum swamp
preservation). I've added a table at the end that summarizes the impacts and mitigation
proposed and accepted.
There was discussion about the possibility of DOT banking any additional mitigation credits
for future use. Concerns about past decisions that were made in order to agree to an
acceptable mitigation package were discussed. There were also concerns about temporal loss
associated with impacts.
The DOT would like to propose that the total mitigation acreage (91.94 Ac) provides adequate
compensation for wetland impacts (6.9 Ac) associated with U-92 A/B corridor. This proposal
1

is to close out the 3rd Street Mitigation Site, as it has completed the 5 year monitoring
requirement.
The impact numbers and mitigation numbers were what I found while looking through our files.
If anyone has any additional information, please let me know.
Thank you,
Byron Moore

63 acres Cypress-Gum Swamp Preservation
1.1 acres Tidal Marsh Wetland Restoration
12.7 acres Tidal Marsh Wetland Enhancement

3`d Street Planted Acreage 0.96 acre shrub (BLH)
0.79 acre trees (BLH)
Total 1.75 acres (BLH)
1.75 acres (total planted) - 0.92 acre shrub (take out area under bridge) = 0.83
acres tree (available)
1.3 acres (needed) - 0.83 acres (trees) = 0.47 acres BLH (deficit)
The list above summarizes the wetland impact acreages and mitigation acreages
for U-92A/B. The 3`d Street Site had a deficit of 0.47 acres of BLH. The total
mitigation acreage provided (12.91 ac of additional Tidal Cypress/Gum Swamp
Restoration, 1.1 ac of additional of Tidal Marsh Wetland Restoration, as well as
75.7 additional acres of wetland Preservation/Enhancement) offsets this 0.47
acres of deficit.
