Project is within Jordan Lake Watershed. Additionally, the town of Cary requires a 50' buffer beyond the State Regulated Jordan lake watershed buffer.
E. Impact Justification and Mitigation O
1. Avoidance and Minimization
1a. Specifically describe measures taken to avoid or minimize the proposed impacts in designing the project:
Mitigation measures employed during Project development include the avoidance of direct impacts to WA and WB and protection of existing water
quality through the use of appropriate erosion and sediment controls and best management practices (BMPs). Tree clearing activities have been
minimized to the maximum extent practical allowing for Project completion.
1b. Specifically describe measures taken to avoid or minimize the proposed impacts through construction techniques:
Culvert length reduced as much as practical by the use of headwalls. Duke has attempted to minimize and avoid regulated resources to the extent
practicable. However, complete avoidance was not feasible due to the area required to support the infrastructure improvements in the Project area.
2. Compensatory Mitigation for Impacts to Waters of the U.S. or Waters of the State
2a. Does the project require Compensatory Mitigation for impacts to Waters of the U.S. or Waters of the State?
Yes No
2b. If this project DOES NOT require Compensatory Mitigation, explain why:
No compensatory mitigation is proposed at this time, as we believe adverse environmental effects of the proposed activity are no more than minimal. Use of appropriate culvert construct
techniques in such a manner that the original stream profiles are not altered and allow for continued aquatic life movement during low flows.
F. Stormwater Management and Diffuse Flow Plan (required by DWR) O
1. Diffuse Flow Plan
1a. Does the project include or is it adjacent to protected riparian buffers identified within one of the NC Riparian Buffer Protection Rules?
Yes No
What type of SCM are you providing?
Level Spreader
Vegetated Conveyance (lower SHWT)
Wetland Swale (higher SHWT)
Other SCM that removes minimum 30 % nitrogen
Proposed project will not create concentrated stormwater flow through the buffer
2. Stormwater Management Plan
2a. Is this a NCDOT project subject to compliance with NCDOT's Individual NPDES permit NCS000250?'
Yes No
2b. Does this project meet the requirements for low density projects as defined in 15A NCAC 02H .1003(2)?
Yes No

2c. Does this project have a stormwater management plan (SMP) reviewed and approved under a state stormwater program or state -approved local government stormwater program?
Yes No
N/A - project disturbs < 1 acre
2d. Which of the following stormwater management program(s) apply:
Local Government State
Local Government Stormwater Programs
Phase II NSW USMP Water Supply
