Folks —After sending out the approach memo for UT3 at the Cross Creek Ranch site, we had a follow-up conference call
and email exchange with Kim, Erin, and Casey. The result of those discussions is that we will propose three reaches for
UT3. The first reach will be approximately 792 LF of restoration at the upstream end of the stream. The second reach
will be 848 LF of "lumped" enhancement II consisting of a few different sections with different treatments similar to
what was proposed in the memo. The lower 321 LF will be a short preservation reach. A map is attached to show the
three separate reaches. Each reach will be described in more detail in the upcoming draft mitigation plan. Both Erin and
Kim indicated that they would need to review the mitigation plan before agreeing on credit ratios, so we will hold off on
further discussion of proposed ratios until the draft mit plan is submitted late this year. Erin and Kim did not think a final
version of the memo was necessary, so I'm sending this email as the final communication on this until the draft mit plan
is submitted. Please let me know if there are any questions or concerns. Thanks.
Jeff

Subject: Cross Creek Ranch UT3 Approach Memo
All — One of the outcomes of the Cross Creek Ranch post -contract site visit was a request by members of the IRT that the
treatments and crediting for the different sections of UT3 be planned and discussed in a memo to be sent out to the
IRT. Here is the comment from the post contract meeting summary:
UT3 was walked from upstream to downstream, and it was noted by the IRT that the reach is in varying condition which
will require fluctuating levels of treatment and design. Wildlands will provide a follow-up memo including a map and
table that outline lengths, approaches, and associated crediting ratios for UT3 and provide it to NCDMS and the IRT for
approval prior to major design efforts.
The follow-up memo is attached. We look forward to your feedback on this memo and specifically if you agree with our
proposed approach and crediting for the stream. Please let us know if we can move forward with the 2.5:1 credit ratio

for the entire UT3 stream and the treatments we have proposed for that stream. Please feel free to contact me if we
need to discuss. Thanks.
