Derita Branch Sanitary Sewer Project Supplemental PCN Information B.3a. - The proposed Derita Branch Tributary Sanitary Sewer Improvements Project corridor alignment starts from the existing sanitary sewer located in a grassed area next to Little Sugar Creek and north of Cullman Avenue, within a contaminated industrial site. The corridor extends to the east, parallel to Little Sugar Creek and crosses perpendicular under Little Sugar Creek and into a forested upland. A branch line of the sewer crosses Derita Branch to tie to the existing sewer. The sewer corridor then extends between Derita Branch and existing development to North Tryon Street as depicted in the attached plans titled"2021_09_15_Derita_SS_Fullsize_Phase 1.pdf. The temporary stream impacts from the sewer installation are depicted in the attached impact plans titled "Derita _401_404_Phase 1.pdf with restoration details included. The project corridor is surrounded by mostly industrial and commercial properties located along Cullman Avenue and North Tryon Street. This is Phase 1 of a two -phased project. B.3d. - Charlotte Water (via subcontract with BRS/STV Joint Venture) proposes to build the Derita Branch Tributary Sanitary Sewer Improvements Project to serve the demands of the growing area since the existing sanitary sewer has reached capacity and is at the end of its design life. The Derita Branch Sanitary Sewer Improvements Phase 1 will then continue the required sewer improvements as Derita Branch Phase 2. B.3e - The Derita Branch Tributary Sanitary Sewer line replacement involves the installation of gravity sewer pipes between Cullman Avenue and North Tryon Street. The proposed corridor alignment starts from the existing sanitary sewer located in a grassed area next to Little Sugar Creek and north of Cullman Avenue, within a contaminated industrial site. The corridor crosses as a dewatered open cut, perpendicular to and under Little Sugar Creek. A branch line of the sewer crosses Derita Branch as a dewatered open cut to tie to the existing sewer. See attached plans titled "2021_09_15_Derita _SS_Fullsize_Phase 1.pdf. The temporary stream impacts from the stream dewatering and sewer installation are depicted in the attached impact plans titled "Derita_401_404_Phase 1.pdf with restoration details included. Heavy equipment including tracked back-hoe/front end loaders may be used. This is Phase 1 of a two -phased project. E.1 - The Derita Branch Tributary Sanitary Sewer Improvements follows the existing sewer alignment to the greatest extent practicable and has limited the proposed stream impacts to temporary dewatering impacts. The open cut installation will be followed by the restoration of the stream bed and banks to original contours.
