Moriah Road, Chapel Hill, NC PIN #s 9890-84-9934, 9890-94-5812, 9890-95-8043, 9890-83-5996 & 9890-74-0792 Sage Project #2021.153 Dear Mr. Jones, Sage Ecological Services, Inc. (Sage) is requesting an appeal to the stream determinations for the above -mentioned properties which was performed by Town of Chapel Hill (TOCH) staff on January 28, 2022, and February 2, 2022. The determination results were provided in an administrative decision letter prepared by Allison Weakley dated March 4, 2022. Due to the significant differences between the original determination conducted by Sage (November 2021) and TOCH (January and February 2022), an additional field assessment was performed during a stream and wetland field review held with April Norton of the US Army Corps of Engineers (USACE) on March 15, 2022. The attached post -review field map and forms are a result of the meeting held with Ms. Norton. Specific conclusions formulated during the USACE meeting include differing start points for intermittent Features E and G. These are identified by flags placed by Sage during the field review on March 15, 2022. Additionally, Features L and K were determined to exhibit indicators of less than an intermittent flow regime.
