Montague Division 5 Environmental Specialist JAMES H. TROGDON, III SECRETARY Subject: Pipe replacement on SR 2511 (Grasshopper Road) in Wake County. USACE Construction of this project is authorized under the following USACE Section 404 Nationwide Permit (NWP): NWP 3 (Maintenance) The proposed activities meet the conditions (see attached) of the Department of the Army Section 404 non-reporting Nationwide Permit (NWP) 3. The proposed impacts do not exceed the 1/10 acre of loss of Waters of the United States. Additionally this project does not involve impacts to a special aquatic site. Construction must comply with all pertinent conditions. NCDEQ-DWR Construction of this project is authorized under the following NCDEQ-DWR Section 401 Water Quality Certificate (WQC): WQC No. 4132 (Maintenance) Construction must comply with all pertinent conditions (see attached). BUFFERS Access for construction involving dewatering and the pipe installation will impact less than 40LF of riparian buffers within the Neuse River Basin, so this maintenance activity is EXEMPT. If you have any questions or need additional information, please contact me at hwmonta u�e(c�r�,ncdot. o�v or at (252)598-5106. cc: Mr. Donald Pearson, Jr., EI, CPESC; NCDOT REU Field Operations Engineer MailingAddress: Telephone: (919)220-4600 Location: NC DEPARTMENT OF TRANSPORTATION Fax: (919) 560-3371 2612 NORTH DUKE STREET DIVISION 5 OFFICE Customer Service: 1-877-368-4968 DURHAM, NC 27704 2612 NORTH DUKE STREET DURHAM, NC 27704 Website: www.ncdot.gov CS# 17-27-03 f/t.;� Yr'.'. rl e `�+� �` k • 1 ,��w` }T*y�4 � i _ � � � •� � �,r f`�'�'3f�1 L4i4 b Road: SR 2511 (Grasshopper Road) Cotintv: Wake River Basin: Neuse Stt-eam Name: UT to Poplar Creek Lat, Lon�: 35.7385409°N, 78.4661902°W HUC: 03020201 NCDENR-DWQ Index Number, Stream Classification: 27-35, C NSW Existing sti2ict�ire: 2@36" RCP that is SOft long with separated joints Note: This structure and roadway failed following HLlrricane Matthew.

Rip rap will be installed underlined with geotextile for long term stability sun•ounding the headwall tie-ins. Note tl�at existin� bedrock will prevent 20% burial, however as �nuch btuial as �ossible will be accomplished through excavation as blasting rocic froin the streainbed to achieve l�urial is not proposed. Neuse Buffers: Access for construction involving dewatering and the pipe installation will impact less tha�� 40LF of riparian buffers within tl�e Neuse River Basin, so this maintenance activity is EXEMPT. Dewaterin�: This stream will requiie water management. Impervions dikes will be installed in the streambed upstream and downstream of the work site for contaiiullent and to maultaiu a dry work. A clean water punlp arouild would be used to maintaiil a diy work area. I��pervious dilce materials will be reinoved once the work is complete. Pennanent iinpacts: lOft of fill in surface water is proposed with the longer pipe in addition to +/-lOft of rip rap on streain bailks (Sft upstream and Sft downstream). Note rip rap in the sneam cha�nel downstreain of the crosslule is froin iecent open cut of the stream foi a utility relocation by otllers. Teinporary ilnpacts: l Oft de�watering (Sft below pipe outlet and Sft above pipe inlet) Protected s�pecies information: No habitat for dwarf wedgemussel, Michaiix's sumac, nor red-cocicaded woodpecker exists at this crossing, neither lias any occurrences been recorded at this location. No trees will be removed impacting habitat for the Northern long-eared bat. Wetland I1lformation: Although this site is inapped as Hydric (Cm —C1lewacla), i10 wetlands exists withui the consti-uction footprint Cultural Resources: Review of the SHPO GIS mapping reveals no cultural resources, no historic stnictLires, nor properties at this crossing.
