Describe the existing conditions on the site and the general land use in the vicinity of the project at the time of this application: Deteriorated low -head dam causing streambank erosion, sedimentation, and impediment to aquatic passage. The condition is threatening nearby infrastructure, homes and property. 3b. List the total estimated acreage of all existing wetlands on the property: There are no wetlands within the project area. There do not appear to be wetlands on the property. 3c. List the total estimated linear feet of all existing streams (intermittent and perennial) on the property: 520 linear feet of perennial stream 3d. Explain the purpose of the proposed project: Remove low -head dam and associated debris, stabilize and restore the streambank, improve aquatic passage. 3e. Describe the overall project in detail, including the type of equipment to be used: The existing deteriorated low -head dam and associated infrastructure will be removed. Rock and concrete material not reused in the project will be removed from the site and disposed of properly. The dam has a total maximum height above the downstream channel invert of approximately 5.65 feet. The total project length will not exceed 100 linear feet. Stream flow will be pumped around the project area and a filter bag(s) will be used to trap sediment at the downstream end of the pump around system. Sediment trapped behind the dam (estimated to be 10 cubic -yards maximum) will be removed once the pump around has dried the area sufficient for mechanical removal. Sediment will be removed from the stream using a small track -mounted excavator and hand tools and will be transferred directly into a truck/loader bucket without stockpiling sediment on the ground. Sediment removal will not proceed past/deeper than the elevation of the original streambed. The eroding streambanks on the river left and right will be stabilized using natural channel design techniques including geo-lifts, minor grading and benching. Pre-existing stream dimensions will be restored within the project area. Three rock cross -vanes will be installed to step the stream down gradually from the elevation of the foundation of the dam to the downstream channel elevation without creating vertical drops in channel flow greater than one feet. Stormwater piping exiting the river -left streambank will be repaired, extended and terminated at the channel invert elevation and stabilized with appropriate rock outlet protection. All disturbed areas of the streambank below two- times bank full elevation and within 20 feet of the stream will be stabilized with a combination of riparian seed mix (ENRST Seeds NC Mountain Riparian Mix-ENRMX-304 or similar), an annual grain suitable for the season, native live stakes (Silky Dogwood, Elderberry, Ninebark), wheat straw mulch and 400 gram per square meter coir fabric installed per manufacturer's specification. The project area will be irrigated in periods of dry weather until a six-inch stand of grassy vegetation is established over the entire site. The North Carolina State Historic Preservation Office (NC SHPO) website has been reviewed for the project area an NC SHPO has been provided this PCN to ensure no historic structures will be impacted by the project. Attachments to the PCN include an Agent Authorization Form, Stream Profile Drawing including construction details and Photographs with Descriptions of the project area. Page 4 of 12 4.

ANCHOR STRAW BY TACKING MTN ASPHALT, WTTIND, ROVING OR BY CRIMPING NTH A MULCH ANCHORING TOIL MAINTENANCE: SATISFACTORY STABILIZATION AND EROSION CONTROL REQUIRES A COMPLETE VEGETATIVE OD1iER. EVEN SMALL BREACHES IN VEGETATIVE COVER CAN EXPAND RAPIDLY AND, IF LEFT UNATTENDED, CAN ALLOW SERIOUS SOIL LOSS FROM AN OTHERWISE STABLE SURFACE. A SINGLE HEAVY RAIN IS OFTEN SUFFICIENT TO GREATLY ENLARGE BARE SPOTS, AND THE LONGER REPAIRS ARE DELAYED, THE MORE COSILY THEY BECOME. PROMPT ACTION WILL KEEP SEDIMENT LOSS AND REPAIR COST DOWN. NEW SEEDLINGS SHOULD BE INSPECTED FREQUENTLY AND MAINTENANCE PERFORMED AS NEEDED. IF RILLS AND GULLIES DEVELOP, THEY MUST BE FILLED IN, RE -SEEDED, AND MULCHED AS SOON AS POSSIBLE DIVERSIONS MAY BE NEIL NEEDED UNTL NEW PLANTS TAHOD. MAINTENANCE AS EXTEND BEYOND THE SEEDING PHASE. (COMPLETE VEGETATIVE COVEN Is REQUIRED REGARDLESS OF COUNTY ISSUANCE OF A CERTIFICATE OF OCCUPANCY AND FINAL PAYMENT WILL NOT BE AWARDED UNTIL COMPLETE ESTABLISHMENT OF VEGETATIVE COVEN.)
