Impact Justification (Avoidance and Minimization) Specifically describe measures taken to avoid the proposed impacts. It maybe useful to provide information related to site constraints such as topography, building ordinances, accessibility, and financial viability of the project. 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 nronosed pipins? alil;nment is the same as the_existin>; raw water transmission line so that the existing line maybe removed as the new line is installed. The ali~mnent does deviate from the existingpipeline in one area in order to avoid disturbance of a privately owned pond. Page 9 of 13 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 March 9, 2000, mitigation will be required when necessary to ensure that adverse effects to the aquatic environment are minimal. Factors including 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. Any application lacking a required mitigation plan or NCWRP concurrence shall be placed on hold as incomplete. An applicant may also choose to review the current guidelines for stream restoration in DWQ's Draft Technical Guide for Stream Work in North Carolina, available at http • //h2o. enr.state.nc. us/ncwetlands/strm gide.html. 1.

Kivett llr. at N. Pendleton St. The existing ROW has been maintained in an open condition for the most part, but in others has been covered by a parking lot and amid- successional forest. Several changes have been made in the new ROW to avoid existing ponds and to provide a perpendicular crossing of the railroad tracks. The field work was performed an September 8, 2005, with the description beginning at the pump station and ending at the treatment plant. To assist in the identification of potential plant communities and species of concern, the data base of the NC Natural Heritage Program for the 13igh Point East USGS quad was downloaded. No communities are listed, although the list includes three taxa, all of State concern: Greensboro Burrowing Crayfish - Cambarus catagius - a current record American Barberry - Berberis carrculensis - a historic record Piedmont Horsebalm - Callinsonia tuberoses - a historic record The NC Natz~ral Heritage Program List of the Rare Animal Species of North Carolina does not list a habitat far the Crayfish. No comments are possible for this species as to potential habitat slang the ROW. Although both plants are Hated as historic records that have not been documented in recert years, these were searched for during the field work. Also, any unusual species occurrences, based an the field knowledge of the survey team, were considered as worthwhile reporting, if natal. Alt potential wetland areas were tested for soil color and plant species composition. Nine creek crossings will be made, eight of these are along the existing ROW, one is new as a result of an ad}ustment in the location of the ROW to permit a perpendicular crossing of the railroad. Ad}ustments were possible to avoid impacting one well-defined wetland. One small (1,000 s.f.), marginal, potential wetland (the soils were mostly bright, but the plant species indicatai a possible wetland) was encountered behind lot 20S Brookview Circle. This is described in more detail in the sequential write up below. HAEitTAT ANALYSIS • ENi~ANGF.REtJ {='L1~NT STIiDtES - RESTORATION OF' HABI'i"A`rS • WETLAND MtTtGATiC71V • MONIT'QRfNG S m statio the ROW immediately crosses an unnamed tributary of the Leaving the pu p n, Deep River (Crossing No. 1). The crossing is above the creek and the supports will be retained far the replacement. The ROW is mowed periodically and supports a mixture of annual and perennial herbaceous species, with an occasional woody seedling or shrub in the ROW, and a border of saplings. Typical of the fall-btooming herbaceous species are: two Sunflowers (Helianthus microcephalus and H. diuaricatus), Joe-Pye Weil (Eupatorium fYStulosum), Beggar Ticks (Bidens spp.), Beggar Lice {Desmodium spp.}, Black-eyed Susan (Rudbeckia laciniata), Brown-eyed Susan (Rudbeckia julgiakr), Coneflower (Rudbeckia laciniata), Black Cohosh (Cimicifugrx racemasa), Blazing Star (Liatris squarrosa}, Lespedeza (Lespedeza bicolor), Verbesina (Yerbesina occidental3s}, two species of Elephant's-foot (Eleplumtopus carolinianus and E. tomentosus), Microstegium (Microstegium vimineum), and Wild Rye Grass (Elymus virginictts). Woody sides as seedlings in the ROW and saplings along the edges include Virginia Pine (Pines virginiana), White oak (Quercus alba), Red maple (Ater rubrum), White ash (Fraxin:ts americarnr), Sweetgum (Liquidambav'styruc~ua}, Sycamore (Platamis occidentalis), Mimosa {Albizia julibrissin), Hazelnut (Corylus a-nericana), Witch-hazel (Hamamelis virginiana}, Redbud (Cercis caruxdensis), and Coralberry (Symphoricarpos orhiculatus). Creek crossings No. 2-6 occur in the open, existing ROW. At the residential area at Brookview Circle, it passes through yards, with scattered trees, then behind the homes at creek crossing No. 6. Between the creek crossing and lot No. 245, the homeowner has dug a ditch to carry storm water from his Iot toward the creek. The ditch empties on to the floodplain, then drains into the creek. The vegetation here supports Cardinal Flower {Lobetia cardinarlis) [FACW+I, Brown-eyed Susan [FAC+], and Sensitive Fern (Onoclea sertsibilis) [FACW]. The area is approximately 1,404 sf, (20 ft. x 54 ft.). The soil is slightly mottled. The ROW then crosses N. Scientific St., at creek crossing No. 7 and passes under the parking lot of an apartment complex, emerging at creek crossing No. 8 at the playground of the complex. Leaving the complex, the ROW enters a secondary growth, woodland that has been allowed to develop in the ROW. This extends all the way to the railroad crossing opposite Cedraw Park. The woody vegetation inchides trees 6 in. to 18 in. diameter breast height (dbh}, with the average dbh being less than 10 in. The species include Yellow poplar (Liriodendron tuiipifera), Loblolly pine (Pirrus taeda), Sycamore, White oak, Black cherry (Prunes serotina), Red maple, Sweetgum, Red mulberry (Mores rubra), Dogwood, and Hazelnut. Near Gedrow Park, the new ROW continues SW, parallel to the railroad track, through a forest that has had slightly different management. The trees are mostly oak and hickories and have been timbered, so that the resulting forest has been formed from stump sprouts, producing trees with multiple boles. Since dbh is measured around all the boles for one specimen, the dbh measurements are not representative of the single bales. However, some of these reach 24 in. to ~4 in. dbh. The species are mostly Red oak (Q. rubra), White oak and Sweet pignut hickory (Carya avcrdis). The ROW then crosses into Cedrow Park, passing along the SE border of the park, crosses the creek at the new crossing, Na. 9, and parallels an existing park maintenance road to the junction with an existing sewer Line ROW, where it turns SW using the sewer tine ROW. This new alignment allows the line to maneuver around several ponds. An adjustment was made in the proposed new alignment to miss a wetland near the junction with the existing ROW. This existing ROW is open all the way to the water treatment plant facility. There are no recommendations regarding species of concern or wetlands for this project. Jam F. Matthews and Lisa R.
