Describe the existing conditions on the site and general land use in the vicinity of the project at the time of this application: The site consists of a vacant floodplain field adiacent to Page 6 of 15 downtown Newland. The North Toe River transects the proper from south to north The stream classification for the North Toe River on this ~rop~ is W -V, Tr (,Troutl according to the North Carolina Division of Water Quality An historic levee exists along portions of the streambank on the property. During the last site visit on February 5, 2007, a beaver dam was observed in the river channel The property was recently purchased by the Town of Newland and is not currently used The property has been historically used as a hay field The eeneral land use in the vicinity of the site is commercial to the east and residential to the west. See the attached photos for a representative view of the current site conditions 10. Describe the overall project in detail, including the type of equipment to be used: The Town of Newland would like to develop the property for use as a public rg een space The project will consist of two phases. Phase 1: The first phase consists of constructing a 1 4-acre stormwater wetland on the eastern portion of the property_(See attached plan sheet for the_,_proposed wetland footprint and contours). Stormwater runoff from downtown Newland will be routed throu the wetland for treatment prior to discharge to the North Toe River Stormwater wetlands are effective at removing sediment. nutrients. metals. and chemicals from runoff A flashboard riser outlet structure will be utilized to control the water surface in the wetland The wetland was designed to capture and treat the runoff produced by the first flush (,precipitation = 1 2 inches) from a 17-acre drainage area from a portion of downtown Newland The outlet structure was designed to drawdown this volume of water over a 72-hour period to optimize the stormwater treatment. An emergenc~pillway was designed to convey and discharge the runoff from sienificant rainfall events ~>2-year storml at non-erosive velocities The proposed vegetation for the constructed wetland is presented below Phase Z: The second phase of the project will consist of streambank stabilization in eroding areas on the North Toe River. The beaver dam will be removed if it still exists on the property once construction begins. See attached plan sheet for the proposed stabilization measures. Streambank stabilization structures such as rock cross vanes and single vanes will be located to protect infrastructure,~rovide public access discourage erosion and improve instream habitat. Construction will not start on the second phase until the end of the trout moratorium on April 15. As stated earlier in Section 9 of this permit application an historic levee exists alongportions of the streambank. Portions of the levee are stabilized with a good stand of willows. The portions of the levee that are not stabilized by native ve etation will be removed to reconnect the river to its floodplain Due to the size of the river it is not feasible to pump around the project site. Instream work in the wet will be minimized The contractor shall work in the dry from the streambanks whenever possible Temporary and permanent seeding Temporary seeding will be used for erosion control during construction and until permanent vegetation can be established. Temporary mixtures include annual ground covers that row quickly and provide ground cover stabilizing the soil and minimizing erosion and sedimentation. If the project is completed in the summer a 5050 mix of Browntop Millet (Panicum ramosum) and Pearl Millet (Penniseteum lacum) applied at a minimum rate of at Page 7 of 15 least 10 Hounds/acre will be used to stabilize the site If the project is completed in the winter. a 50:50 mtx of winter wheat (Triticum aestivum) and rye grain Secale cerealel will be applted at a mtntmum rate of at least 10 Hounds/acre A permanent seed mix will also be applied The permanent seed mix will include warm season gasses cool season grasses, and wetland species and will b applied at 12 15 pounds/acre All permanent species will consist of native perennial ground covers that are suited to bein temporarily inundated Floodplain sites will be mulched again after permanent seeding The seeding mix at these locations will consist of flood plain species Mulching Mulchins will be used to provide temporary protection of soil surfaces from erosion Clean gain straw mulch will be applied uniformly and tacked with hydromulch Permanent vegetation A mixture of container stock and bare root vegetation will be used to plant woodtive~etation Since bare_root stock must be planted while the~lants are dormant the proportion and timing of bare root plantine will depend on the timing of project completion A random assortment of shrub and tree species will be planted along both sides of the streambank and in the floodplain see Vegetation specification below for more detail, Wetland vegetation Permanent wetland vegetation will be planted within the excavated wetland area A combination of seeds. plus and container and bare root stock will be used Species will be selected from the following; list based on availability Juncus effusus Soft Rush Scirpus cyperinus Carex spp Peltandra virginica Iris virginica Pontederia cordata Rosa palustris Sagittaria latifolia Hibiscus moscheutos Asclepias incarnata Monarda didyma Echinacea purpurea Liatris spicata Lobelia cardinalis Lobelia siphilitica Ilex verticillata Lindera benzoin Physocarpus opulifolius Sambucus Canadensis Spirea alba Spirea tomentosa Vibernum cassinoides Aronia melanocarpa Wool Grass Sedges Arrow Arum Blue Flag Pickerelweed Swamp Rose Broad Leaf Arrowhead Swamp Mallow Rose Swamp Milkweed Bee Balm Purple Cone Flower Blazing Star Cardinal Flower Great Lobelia Winterberry Spicebush Ninebark Elderberry White Spirea Pink Spirea Wild Raisin Black Chokeberry Page 8 of 15 Streambank vegetation Streambank disturbance will be limited to areas of structure installation and levee removal.

Explain the purpose of the proposed work: To increase the stability of the North Toe River on the Town's property and to reduce erosion and sediment impacts downstream while increasing habitat. Furthermore to treat runoff from the Town of Newland prior to discharge to the North Toe River. This site has tremendous potential for educational and recreational benefits It will provide and excellent resource for students to get hands on experience in the field of water quality and environmental management. The NC Cooperative Extension "Kids in the Creek" program would be able to utilize this site for watershed water quality and stream ecology education. "Kids in the Creek" is a program that is already well established throw Avery County Cooperative Extension having 1,650 participants in 2005 This site is an ideal location to educate students of all ayes about stream ecology watersheds clean water and the protection of our natural resources. This site will also serve as a model for landowners in the county to learn how they can implement best mana ement practices~BNIP'sl on their land to protect and restore their streams. Agencies will have demonstration workshops and tours at the project site to educate others in this field of watershed mana eg ment Page 9 of 15 IV.
