Restoration Systems had originally obtained a permit for this project (DWQ Project # 10 -0099) to restore streams and wetlands within an approximately 65 -acre site in the Neuse River Basin. The mitigation plan includes fill within the upstream, wooded reaches of Kennedy Mill Branch and the Main Tributary to Kennedy Mill Branch to raise the bed elevation of these streams in order to complete priority 1 stream restoration in agricultural portions of the Site. Fill within these reaches will be tapered back to the existing grade at the upstream extent of the Site. In the original permit application existing reaches were expected to be partially filled within 549 linear feet of Kennedy Mill Branch and 254 linear feet the Main Tributary. However, based on additional field measurements conducted after approval of the initial permit package, it was determined that partial fill within existing reaches will need to extended beyond initial estimates. Modified fill numbers for partial fill within existing reaches are as follows. Stream Reach Total Partial Fill Length Kennedy Mill Branch 1334 linear feet Main Tributary 853 linear feet. Additional impacts within the Site resulting from fill of abandoned stream channels and ditches, and construction of priority 1 stream restoration will not change from the original permit application.

Describe the existing conditions on the site and the general land use in the vicinity of the project at the time of this application: Surrounding area land use is primarily agricultural, with some low- density residential housing. Onsite land use is characterized by hardwood forest, agricultural land (row crop production), and pasture (livestock). Riparian zones and wetland areas are primarily composed of herbaceous vegetation with sparse hardwood canopy species along the streams. Riparian vegetation adjacent to restoration /enhancement reaches of the Bank is sparse and disturbed due to livestock grazing, bush hogging, and regular maintenance activities. 3b. List the total estimated acreage of all existing wetlands on the property: Currently 2.2 acres of jurisdictional wetland exist within the Bank including 1.7 acres of cleared jurisdictional wetland and 0.5 acre of forested jurisdictional wetland. 3c. List the total estimated linear feet of all existing streams (intermittent and perennial) on the property: 9440 linear feet of total existing stream (8660 linear feet perennial stream and 780 linear feet of intermittent stream) 3d. Explain the purpose of the proposed project: Bank activities are proposed to 1) restore (priority 1) 5322 linear feet of stream, 2) restore 1137 linear feet of braided Coastal Plain stream, 3) enhance (level 1) 1969 linear feet of stream, 4) enhance (level 11) 1837 linear feet of stream, 5) restore 29.0 acres of jurisdictional wetland, 6) enhance 1.5 acres of cleared jurisdictional wetland, 7) preserve 0.5 acres of forested jurisdictional wetland, 8) establish a minimum 50 -1oot wooded riparian buffer adjacent to wetlands and streams, and 9) establish a permanent conservation easement. 3e. Describe the overall project in detail, including the type of equipment to be used: Primary activities designed to restore the Bank include 1) belt -width preparation and grading, 2) channel excavation, 3) Installation of channel plugs, 4) backfilling of the abandoned channels, 5) partially filling upstream reaches of Kennedy Mill Branch and the Main Tributary in order to start priority 1 stream restoration in agricultural fields, 6) installation of in- stream habitat, 7) installation of marsh treatment areas to intercept stormwater flows prior to entering the Bank, 8) removing spoil, 9) filling drainage ditches, 10) removing invasive species, and 11) planting with native, forest species. Equipment expected to be used for Bank construction include track hoe, track truck, pump around, and bull dozer. Page 3 of 13 PCN Form — Version 1.3 December 10, 2008 Version 4.

Page 8 of 13 PCN Form — Version 1.3 December 10, 2008 Version D. Impact Justification and Mitigation 1. Avoidance and Minimization 1 a. Specifically describe measures taken to avoid or minimize the proposed impacts in designing project. Current land use practices including the maintenance and removal of riparian vegetation; ditching of adjacent riparian wetlands; and relocation, dredging, and channelization of onsite streams have resulted in degraded water quality and unstable banks (stream entrenchment, erosion, and bank collapse). The project was designed to restore stream and wetland function at the Site, thereby providing functional uplift by removing nonpoint sources of pollution associated with agricultural activities, reducing sedimentation, providing shallow marsh treatment areas to intercept surface waters, promoting floodwater attenuation, reestablishing stream stability and the capacity to transport watershed flows and sediment loads, improving aquatic habitat and providing wildlife habitat. Sediment and erosion control practices will be implemented throughout. 1b. Specifically describe measures taken to avoid or minimize the proposed impacts through construction techniques. With the exception of channel work and filling of abandoned channels and ditches, equipment will not be used within wetlands and all planting within wetlands will be done by hand. Disturbance to wetland areas by equipment used for channel work (including filling of abandoned channels and ditches) will be minimized by keeping equipment footprints and movements within wetland areas to a minimum. All channel work within stream enhancement (level 1) reaches will be completed in a manner to cause as little disturbance to the existing vegetation as feasible and desirable hardwood trees greater than 4 inches in diameter at breast height will be avoided to the maximum extent possible. 2.
