I believe that 796 square feet of Zone 2 mitigation is from the original application, which was a typo, I sent the updated application to the USACE a few weeks
ago, and it looks like I did not attach you on the email as well, I apologize for the mix up, Here are the updated pages that were sent to the Corp, Hopefully this
will clear up the numbers being slightly off, Feel free to call with any questions,
Thanks,

I just have a question regarding the calculation of buffer mitigation credits, The letter states that 4,392 credits are being purchased from EBX, but when I do the
calculation based on the permanent impacts listed in the application, I get 4,452 square feet of required mitigation (1,086 X 3 = 3,258 plus 796 X 1.5 = 1,194j,
Please let me know if I've done the calculation incorrectly, Thank you,

Cherri,
Please find attached with this email the updated Statement of Availability Letter from EBX, increasing the buffer mitigation area to include the impacts in Zone
2. If you need any further information, don't hesitate to call,
Thanks,

Impact Justification and Mitigation
1.
Avoidance and Minimization
1 a. Specifically describe measures taken to avoid or minimize the proposed impacts in designing project.
Existing Linear transportation system is super - elevated road which drains runoff toward the direction of the proposed impacts. The proposed impacts
result from new drainage proposed at the natural low points for the project. Design considered connecting new storm directly to existing 60 -inch CMP
Culvert in attempt to avoid the impacts; however, the amount of cover above the existing culvert is inadequate to support storm connection.
1 b. Specifically describe measures taken to avoid or minimize the proposed impacts through construction techniques.
A Temporary impervious dike and pump- around measures will be utilized during construction to divert clean water upstream around the construction
zone through the existing 60 -inch CMP. The construction zone will be de- watered and pumped into a special stilling basin to minimize sediment
loading prior to discharge of the effluent back into the stream and wetlands.
2.

2a.
Does the project require Compensatory Mitigation for
impacts to Waters of the U.S. or Waters of the State?
