Describe the existing conditions on the site and the general land use in the vicinity of the project at the time of this application:* The Subject Property, located in Blowing Rock, NC, is surrounded on the southern, western and eastern by deciduous forest as well as some residential homesites. Currently, there is a building on the property used for storage for the landowner as well as a parking lot. The Middle Fork New River runs through the northern section of the property, with a stonework and concrete bridge providing access to the parking lot area. An unnamed tributary flows from southeast to north within the southeastern quadrant of the property. The northern boundary lies adjacent to US Highway 321 South. Primary land use in the vicinity includes residential and commercial developments as well as transportation. The Blue Ridge Parkway, a national scenic byway, is also located close to the site. 4b.

Explain the purpose of the proposed project:* The purpose of this project is to develop mixed -use residential housing facilities and associated storage and parking areas. 41. Describe the overall project in detail, including indirect impacts and the type of equipment to be used:* Currently, the plan is to build a single one -bedroom and three two -bedroom cottages, as well as six smaller "tree houses" for a total of ten residential units. Plans also include a future commercial space, which will likely be used for storage. Parking spaces will also be added to the existing parking area on -site. An existing bridge which crosses the Middle Fork New River will have its footings repaired as part of this project. A 40 foot existing culvert on Ur1 will be replaced with a 65 foot culvert, and .02 acres of wetland will be filled as part of the parking area expansion and associated drainage pipe installation. A variety of equipment will be used during the construction of this project and may include dump trucks, skid steers, track hoes, back hoes, and other heavy equipment. 4j.

Avoidance and Minimization 3i. Total temporary stream impacts: 30 1a. Specifically describe measures taken to avoid or minimize the proposed impacts in designing the project: Several building footprint locations were considered during the design phase of the project. The final design has the least cumulative impacts to jurisdictional waters. Impacts to wetlands and streams were taken into consideration with the building design. Buildings located near streams were designed as tree -houses with cantilevered decks to reduce tooter impacts to stream riparian buffers. Buildings were limited to 10 units to avoid zoning requirements for expansive additional parking. Existing pavement was utilized during planning and design to minimize new impervious areas thus reducing impacts to water quality via stormwater runoff. 1b. Specifically describe measures taken to avoid or minimize the proposed impacts through construction techniques: All streambank disturbances will be stabilized same day and covered with coir matting and live -staked to reduce sedimentation during construction. Only well maintained equipment will be used; no leaks will be tolerated. During the installation of culverts a pump -around system will be used to divert flowaround substrate materials and to prevent excess sedimentation. At the end of each day, disturbed areas will be seeded, strawed, and matted with coconut coir erosion control matting. Al equipment will be newor in very good condition to minimize the potential for hydraulic leaks. Silt fence will be installed to prevent construction runoff from entering streams or wetlands. All remaining disturbed areas will be seeded and strewed once construction is complete. 2. Compensatory Mitigation for Impacts to Waters of the U.S. or Waters of the State 2a.
