The applicant may attach drawings of alternative, lower-impact site layouts, and explain why these design options were not feasible. Also discuss how impacts were minimized once the desired site plan was developed. If applicable, discuss construction techniques to be followed during construction to reduce impacts. The project will use soft en ineerin te~ques and stringent erosion control methods to minimize impact. VIII. Mitigation DWQ - In accordance with 15A NCAC 2H .0500, mitigation may be required by the NC Division of Water Quality for projects involving greater than or equal to one acre of impacts to freshwater wetlands or greater than or equal to 150 linear feet of total impacts to perennial streams. USACE - In accordance with the Final Notice of Issuance and Modification of Nationwide Permits, published in the Federal Register on January 15, 2002, mitigation will be required when necessary to ensure that adverse effects to the aquatic environment are minimal. Factors including Updated 11/1/2005 Page 10 of 14 size and type of proposed impact and function and relative value of the impacted aquatic resource will be considered in determining acceptability of appropriate and practicable mitigation as proposed. Examples of mitigation that may be appropriate and practicable include, but are not limited to: reducing the size of the project; establishing and maintaining wetland and/or upland vegetated buffers to protect open waters such as streams; and replacing losses of aquatic resource functions and values by creating, restoring, enhancing, or preserving similar functions and values, preferable in the same watershed. If mitigation is required for this project, a copy of the mitigation plan must be attached in order for USACE or DWQ to consider the application complete for processing.

Riparian Seeding and Planting Guidelines These guidelines will provide the methods to be used for reestablishing riparian vegetation. They will include seedbed preparation, nutrient enhancement, temporary seeding, permanent seeding, and erosion control. Methodology for planting sod mats, live stakes, and trees will also be presented. Herbaceous Vegetation Cnri mate Prior to sloping stream banks within easement areas the sod on these banks will be removed. Mats should be deep enough to contain a majority of the roots. These mats should be stockpiled for later use. After banks are sloped the mats should be placed from the bankfull elevation down to the normal water line or onto the interberm feature. Mats should be laid as close to one another as possible and pushed into the under laying soil. Openings between mats should be filled with soil and seeded with temporary seed mix. Mats should be fertilized at a rate of 25 lbs. per 1000 sq. ft. and watered using a pump or by dipping water out of the creek with a clean track-hoe bucket Seed Seedbed Preparation: On sites where equipment can be operated safely the seedbed shall be adequately loosened and smoothed. This may require disking and dragging. On sites where equipment cannot operated safely, the seedbed shall be prepared by hand scarifying to provide a roughened surface so that seed will stay in place. If seeding is done immediately following construction, seedbed preparation may be required only on areas where heavy equipment has caused compaction of the ground. Fertilizing: Evenly distribute lime and fertilizer over the area to be seeded using a tractor mounted fertilizer spreader or with a hand held fertilizer spreader. Uniformly mix lime and fertilizer into the top 3 inches of the soil using a drag or hand rake. Where surface materials are predominately gravel and/or cobble, no incorporation is required. Apply lime and fertilizer according to soil test or at the following rates. Per 1000 sq. ft. Per Acre Lime 1001bs. 2 ton 18-46-00 Fertilizer* 121bs. 500 lbs. *(half of fertilizer will be applied in fall at planting and other half in spring) Seeding: Temporary seeding -Use where needed for erosion control, when permanent vegetation cannot be established due to planting season and where temporary ground cover is needed to allow native or woody vegetation to become established. Apply the following vegetation at the listed rates. Fall, Winter, and Spring Seeding Per 1000 sq. ft. Per Acre Japanese Millet '/z lb. 201bs. Winter Wheat 1 lbs. 401bs. Summer Seeding Per 1000 sq. ft. Per Acre Sudangrass 1 lb. 401bs. Browntop Millet 1 lb. 401bs. Seeding: Permanent Seeding -Use in combination with woody plantings on the up-slope side of the riparian area and down to the bankfull elevation. This mixture can be planted at any time but will do best in spring or late fall. Spring planted seed should be treated with a cold wet chill process to maximize germination. Fall plantings should be planted with a lightly sown cool season annual to hold soil and does not need to be chilled. Seeding should be done evenly over the area using a mechanical or hand seeder. A drag should be used to cover the seed with no more than 'h inch of soil. Where a drag can not safely be utilized the seed should be covered by hand raking. All seasons: WNC Riparian Diversity Mix (as described on the attached sheet) 1/a lb. per 1000 sq. ft. and 10 lbs. per Acre Erosion Control: All seeded areas, areas disturbed by heavy equipment, or other areas disturbed by mitigation activities should be protected from erosion by installation of erosion control blankets or matting. Woody Vegetation Live stakes (uprooted material) Live stake material should be dormant and gathered locally or purchased from a reputable commercial supplier. Stakes should be i/z to 3 inches in diameter and living based on the presence of young buds and green bark. Stakes should be kept cool and moist to improve survival and to maintain dormancy. Stakes should be driven into the ground using a rubber hammer or by creating a hole and slipping the stake into it. The ground around the stake should be firmed against the stake after planting. Stakes should be placed so that 75% of the stake is below the ground and 2 or 3 buds are above ground. Stakes should be planted on a 2 - 3 foot spacing and at a density of 160 - 360 stakes per 1000 sq. ft. Bare rooted or potted stock Care and handling: Desirable trees and shrubs on the construction site should be dug and stored. These plants should be stored in a cool moist environment or heeled in. Roots of bareroot stock should be kept moist during planting operations. Bareroot material should only be planted 2 during Winter and early Spring. Container or potted stock shall be kept moist at all times. Do not let roots freeze or dry out prior to planting. Site Preparation: The soil in the area of tree planting should be loosened to a depth of at least 1 foot. This is only necessary on hard compacted soil. Planting: On site material -Transplants should be replanted to the same depth they were originally growing. Potted stock -Planting should be done mechanically or by hand using a shovel. The planting trench or hole must be deep enough and wide enough to permit roots to spread out and down without J-rooting. Potted stock should be planted in a hole 2-3 times the diameter of the root ball and at the same depth as the root ball. When setting plants, be certain to plant them high. Locate the root ball on solid soil and not loose backfill. Wire baskets do not need to be completely removed from large field grown trees. Be sure to remove plastic liners or synthetic burlap materials. Construct an earthen dam 4-6 inches high around the drip zone area of the plant after planting. This will allow for self watering and runoff will be minimized. Bare rooted stock -Bare rooted material can be planted using a hoedad or a dibble bar (see diagram below). Planting slits for bare rooted material should be 6-8 inches in diameter and should be at least 8-12 inches deep. Damaged roots should be trimmed.

It was created from a database compiled by TVA and distributed on CD format as a product called "Banks & Buffers" (Tennessee Valley Authority. 1996. Banks & Buffers, A guide to selecting native plants for streambanks and shorelines; Riparian Plant Selector, Version 1.0; Environmental Research Center and Clean Water Initiative, Muscle Shoals, AL.). As more information becomes available we will add to this list in an effort to encompass as many riparian species native to Western North Carolina as possible. Shrub and tree species listed on the following pages will be planted at mitigation sites as either live stakes, potted stock, balled stock or bare root stock. These plantings will take place in the winter or early spring. Spacing suggestions should be used as guidelines, but can be varied depending on species requirements and landscape objectives. For example species that are commonly found growing in clumped distributions should be planted that way. It is desirable for the final distribution of trees and shrubs to have a more natural, random appearance.
