IMPACTS TO WATERS OF THE UNITED STATES Surface Waters All revisions occur witlun the Neuse River Basin (HUC 03020201). Stream impacts occur at new Site SR1. Stream SZZ at Site SR1 is a highly degraded channel located on the front side of the Fellowship Baptist Church on Muldee Street (near Station 6+28 to 10+78 Lt -SR-1-). Recent evaluations of this stream by a NCDOT Biologist on November 22, 2017 detennined that this stream is classified as a perennial stream across the entire cl�urch property. The channel was classified as a non jurisdictional streanl feature that was not subject to the buffer rule in a previous 2012 determination. A recent plan revision changed the installation of a sanitary sewer line and drainage system in the area of SZZ. The City of Durham indicated that the new drainage structures (2 @ 24 inch reinforced concrete pipes) that discharge into the jurisdictional feature could not be placed above the sewer line and would have to be installed below the sewer line. The recent installation of the 2@ 24 inch reinforced concrete pipes revealed t17at the inverts of the structures are significantly below the adjacent elevation of the perennial stream. Invert elevations of the pipe structures were evaluated and could not be changed. The only practical option was to regrade the stream channel in a slightly lower elevation and place the feature in a Class I rip rap lined channel (see Details CS1 and CP1) from 6+28 to 10+78 Lt —SR1- on Pennit Sheet 4. This work is proposed along the upper part of the stream channel in front of the Fellowship Baptist Church and results in permanent impacts for the stream and buffers. Please see Tables 1 and 2 for the impacts. Table 1.

The USACE has indicated mitigation for the stream loss is not required due to the highly degraded stream. The NCDWR has indicated that stream mitigation and buffer mitigation is not required due to the lack of negative impact on water quality and use of the protection of existing structures category in the Neuse Buffer Rule.
