Lake Corriher and its influent stream, Flat Rock Branch, are designated WS-IV-CA by the N.C. Division of Water Quality (DWQ). Drainage basin area at the dam is approximately 1.9 square miles. Jurisdictional wetlands were delineated according to the Army Corps of Engineers (COE) Wetlands Delineation Manual (Environmental Laboratory, 1987), subsequent COE Regulatory Guidance Letters, and supplementary literature for determining hydric soils and hydrophytic vegetation. The lake level was eight to ten feet below normal pool elevation for several months prior to and during the wetland delineation. Wetland flags Al through A8 delineate the upslope edge of the jurisdictional wetlands in the proposed construction area, and flags B1 through B18 delineate the downslope edge (Figure 2). The area enclosed between the A-line and B-line comprises about 0.7 acre of freshwater herbaceous marsh and shrub/sapling wetland. Dominant plants are alder (A/nus serru/ata), red maple (Acer rubrum), swamp rose (Rosa pa/ustris), lizard tail (Saururus cernuus), blackberry (Rubus species), tearthumb (Po/ygonum sagittatum), knotweed (Polygonum species), soft rush (Juncus effusus), sedges (Carex and Scirpus species), spikerush (E/eocharis species), and grasses (Poaceae). North of the A-line is upland mixed hardwood/pine forest and mowed grass. South of the B-line is the unvegetated portion of Lake Corriher, which constitutes non-wetland jurisdictional waters. Northeast of B18 the shoreline is steep and contains no wetlands. The 5- to 15-foot wide strip of wetlands extending west of B1 and Al is beyond the proposed construction area and was not delineated. RJG&A examined the site for evidence of state and federally protected species. Ten protected species have been reported from Rowan County. Two species are federally listed: the threatened bald eagle (Ha/iaeetus /eucocepha/us) and the endangered Schweinitz's sunflower (He/ianthus schweinitzii). The remaining eight species (two animals and six plants) are listed as endangered, threatened, or special concern under state law. No suitable habitat for any of these species occurs in the project area, and no adverse impacts to these species are anticipated. 11Y 1? 3 i' Soo j so-' 1.2 11 2000 Ft. ) I?_._ it / \\ ? , \ t II r -1?J1? v ?? _ r?

This shall be accomplished with a straight upward, machine assisted, pulling movement on the stump. Extracted stump materials shall be immediately loaded in transport vehicles. The "pushing over" of stumps for extraction, excavating adjacent to stumps to facilitate extraction, and the dragging of stumps across the lake bed to transport vehicles shall not be allowed. All holes remaining as a result of stump extraction shall be left "as is". In the event stumps break off during extraction, the remaining stump structure shall be "saw cut", totally severed by chain saw or equivalent manner, flush to in-place grade, with neat and smooth severed cut surface. The remaining stump material left in place. 1.5.2 Where contract drawings indicate that extracted stumps are to be transported to a designated disposal site, it shall be the Contractor's responsibility to load all parts of all removed stumps, transport same from the project area to the designated spoil site, and dump materials at the spoil site as directed by Town personnel. This shall be accomplished in a safe manner, and in accordance with all federal, state and local statutes, regulations, codes and ordinances associated with activity. Extracted stump materials shall become personal property of the Contractor upon loading into transport vehicles in project area and shall remain so until properly dumped at the designated disposal site. Safe and legal offsite disposal of extracted stumps shall be solely the Contractor's responsibility, including all costs associated with the activity and all required permits associated with the activity. The Contractor shall save and hold harmless the owner and the Engineer from any claims by any other parties as a result of transport or storage activities while the stump materials are his/her personal property. *** END OF SECTION *** ME Project No. 97-0160 Page 02103-2 EARTHWORK AND SITE GRADING ROCK EXCAVATION Drawings or as directed by the Engineers. 1.5.7 If, at the time of excavation, it is not possible to place any material in its proper section of the permanent construction, it shall be stockpiled in approved areas for later use. No extra payment will be made for rehandling stockpiled material. 1.5.8 Those areas outside of the construction area in which the top layer of soil material becomes compacted, due to hauling or to any other activity of the Contractor, shall be scarified and disked to a depth of 411, or as directed to loosen and pulverize the soil. 1.5.9 In cuts, all loose or protruding rocks on the back slopes shall be barred loose or otherwise removed to line or finished grade of slope. All cut and fill slopes shall be uniformly dressed to the slope, cross section and alignment shown on the Contract Drawings, or as directed by the Engineers. 1.5.10 Under certain conditions, sheeting and bracing may be ordered by the Engineers to be left in place. Any sheeting so ordered left in place will be paid for on the basis of the Contract unit price for such work. If no Contract unit price is established for this work, payment will be established in accordance with provisions in the General Conditions of the Contract. 1.5.11 Sheet piling indicated on the Contract Drawings to be placed for the purpose of retaining the stability of soil adjacent to excavations shall be driven to lines and grades indicated thereon and left in place. When so noted, depth of penetration, type and weight of piling shall be as designated on the Contract Drawings. Cost of such permanent sheet piling shall be included in the Contract lump sum price. 1.5.12 Unauthorized excavations (removal of materials beyond indicated subgrade elevations) may be filled and compacted with acceptable material, filled with lean concrete or corrected by extending the indicated bottom elevation of the footing to the lower elevation, as directed by the Engineers. 1.5.13 Rock adjacent to existing structures shall be excavated by drilling and wedging or by other means approved by the Engineers. Openings to be cut into concrete or other masonry structures shall be done by drilling and chipping. Blasting shall not be done at any time in any part of the work where there is a possibility of damaging another structure or item of the project. 1.5.14 Excavations shall not be carried below existing NE Project No. 97-0160 Page 02210-4 I ' EARTHWORK AND SITE GRADING ROCK EXCAVATION Boulders shall not be classified as rock unless larger than 1/2 cubic yard. Should rock be encountered in the excavation, it shall be removed, when removal is required by Engineers, by blasting or other methods approved by the Engineers. Where blasts are made the excavation shall be carefully covered with suitable brush, timber or matting to prevent danger to life and property. The Contractor shall secure all permits required by Law for blasting operations and any additional hazard insurance required, the cost of such permits and insurance to be borne by the Contractor. The Contractor shall strip the rock of over burden, such stripping to be done in sections. No blasting shall be done by the Contractor until he has notified the Engineer and until the necessary cross- sections of the top of the rock have been taken. The Contractor shall determine from borings or other means the nature of the material to be excavated before placing his bid. 1.7 BORROW AND SPOIL AREAS: :-1 1.7.1 Borrow excavation shall consist of excavation made from borrow areas within the limits of the owner's property outside the normal grading limits and/or from areas outside the property when required for the completion of the embankments or for other purposes. Borrow area or areas within the property from which borrow may be obtained will be designated by the Engineers. Borrow excavation shall be made only at these designated locations and within the horizontal and vertical limits as staked or as directed. 1.7.2_ When borrow sources are outside the boundaries of the Owner's property, it shall be the Contractor's responsibility to locate and obtain the supply subject to the approval of the Engineers. The Contractor shall notify the Engineers sufficiently in advance (at least 14 days) of the beginning of excavation in order that necessary measurements and tests can be made. All objectionable material shall be disposed of as directed. All borrow pits shall be opened up immediately to expose the vertical face of various strata of acceptance material to obtain a uniform product. Borrow pits shall be excavated to regular lines, and shall be drained and left in a neat and presentable condition with all slopes dressed uniformly. The borrow excavation shall be handled and placed as specified in these Specifications for excavation and embankment. 1.7.3 If private land is used as a spoil or borrow site, the Contractor shall obtain written permission from the owner of the land, or his agent, and provide the Engineers with a certified copy of such agreement. 1.7.4 Borrow pits shall be excavated in such a manner that they will be self draining. When the Contractor's excavation ME Project No. 97-0160 Page 02210-6 EARTHWORK AND SITE GRADING ROCK EXCAVATION approved spoil areas. 1.8.3 All cuts and fills shall be covered with topsoil to a depth of not less than 4" after compaction. The area to be covered with topsoil includes the embankments, cuts and fills other than for structures or paved areas and all graded areas around the construction site. No topsoil shall be used in the formation of embankments other than that used in the specified exterior cover. 1.9 COMPACTION: 1.9.1 Compact each layer of embankments, backfill and fill soil materials to a 95% maximum density for cohesive soils and 100% for cohesionless soils. Where specifically indicated on the Contract Drawings such areas as lawns, spoil areas, and/or other areas as may be designated on the Contract Drawings or as directed by the Engineers, compaction of soils may be reduced to 85% maximum density for cohesive soils and 90% for cohesionless soils. If such areas permitted to receive less than the 95% level of compaction are not specifically indicated on the Contract Drawings, the Contractor shall compact all fill areas to the specified 95% level. No fill soil material of less than 100 pounds per cubic foot dry density weight shall be allowed in embankments, under structures, ' roadways, footings, foundations, paved areas, or structural fills of any nature. When the maximum dry density exceeds 125 pounds per cubic foot the required compaction may be reduced five percentage points below that specified herein. In the top 3' of fills under paved areas, slabs, footings, embankments, structures, etc., the specified density shall not vary more than 3% more or less that the average density of the compacted soil. ' 1.9.2 Compaction of each layer of fill shall be accomplished by the use of any type of approved compacting equipment that will obtain the specified density at optimum moisture as determined by ' the Engineers in accordance with, the "modified" method of test for moisture density relationship of soils using a 10-pound rammer and an 18" drop, AASHO Designation T180, Method D or ASTM Designation ' D1557, Method D and field controlled in accordance with ASTM D2167 (latest edition). Each layer of embankments and/or fills shall be compacted to the required density and approved before material for the next succeeding layer is placed. Placing and compacting areas shall be kept separate. 1.9.3 Apply water to surface of subgrade or layers of soil material if required. Remove and replace, or scarify and air dry all soil material that is too wet to permit compaction to specified density. 1.10 BACKFILL AND FILL: I ME Project No. 97-0160 Page 02210-8 EARTHWORK AND SITE GRADING ROCK EXCAVATION specified the individual foundation excavations. 1.17.3 If approved by the Engineers, a network of ditches draining into sumps located around the perimeter of the individual construction areas may provide an effective method of dewatering. The rate of dewatering-is dependent upon the number of ditches or lateral extensions. The ditches shall be maintained 31 below the bearing elevation and shall be deepened as required as the excavation perimeter to improve drainage to the sumps where the water may be removed by continuous pumping. When the water level has been lowered, as specified, and, upon approval of the Engineers, the foundation may be excavated to final grade. 1.18 TESTING: 1.18.1 The Contractor shall include in his Base Bid the cost of all testing services required under this Section of these Specifications. The required soils testing shall be performed by an independent testing laboratory, paid for by the Contractor. However, the laboratory selected shall be approved by the Owner prior to commencement of tests. 1.18.2 Specified tests shall be performed on each layer of compacted fill at a rate of one test per 5,000 square feet of compacted backfill or fill. However, in all cases, at least two tests per compacted layer of fill shall be made. Certified copies of all field tests shall be provided the Engineers in duplicate. *** END OF SECTION *** A 1 I ME Project No. 97-0160 Page 02210-12 14 DIVISION OF WATER QUALITY October 24, 1997 I MEMO TO: John Dorney c<, ?+ ??jG FROM: Rex Gleason ? .0 Jl A PREPARED BY: Michael L.

Lake Corriher and its influent stream, Flat Rock Branch, are designated WS-IV-CA by the N.C. Division of Water Quality (DWQ). Drainage basin area at the dam is approximately 1.9 square miles. Jurisdictional wetlands were delineated according to the Army Corps of Engineers (COE) Wetlands Delineation Manual (Environmental Laboratory, 1987), subsequent COE Regulatory Guidance Letters, and supplementary literature for determining hydric soils and hydrophytic vegetation. The lake level was eight to ten feet below normal pool elevation for several months prior to and during the wetland delineation. Wetland flags Al through A8 delineate the upslope edge of the jurisdictional wetlands in the proposed construction area, and flags 131 through B18 delineate the downslope edge (Figure 2). The area enclosed between the A-line and B-line comprises about 0.7 acre of freshwater herbaceous marsh and shrub/sapling wetland. Dominant plants are alder (A/nus serru/ata), red maple (Acer rubrum), swamp rose (Rosa pa/ustris), lizard tail (Saururus cernuus), blackberry (Rubus species), tearthumb (Po/ygonum sagittatum), knotweed (Po/ygonum species), soft rush (Juncus effusus), sedges (Carex and Scirpus species), spikerush (E/eocharis species), and grasses (Poaceae). North of the A-line is upland mixed hardwood/pine forest and mowed grass. South of the B-line is the unvegetated portion of Lake Corriher, which constitutes non-wetland jurisdictional waters. Northeast of 1318 the shoreline is steep and contains no wetlands. The 5- to 15-foot wide strip of wetlands extending west of B1 and Al is beyond the proposed construction area and was not delineated. RJG&A examined the site for evidence of state and federally protected species. Ten protected species have been reported from Rowan County. Two species are federally listed: the threatened bald eagle (Ha/iaeetus /eucocepha/us) and the endangered Schweinitz's sunflower (He/ianthus schweinitzh). The remaining eight species (two animals and six plants) are listed as endangered, threatened, or special concern under state law. No suitable habitat for any of these species occurs in the project area, and no adverse impacts to these species are anticipated. 2u 2000 FT. \\ u.,- II ?' •?

The area designated to be graded shall then be stripped and stockpiled. See also the paragraph in this section covering,tops,6il. 1.5.2 Excavation shall be made to the dimensions shown on the Contract Drawings with due allowance for the minimum space required for form work, etc. The Contractor will be held responsible for the proper shoring and sheeting of all excavations. It shall be the responsibility of the Contractor to protect all excavations from sloughing off and thus destroying firm soil for footings and foundations occurring adjacent to excavations carried to a lower grade. Failure of Contractor to properly protect excavations will result in the Contractor having to make such repairs as required to correct the work. Such corrective measures will be made at the Contractor's expense. % 1.5.3 The rough excavation shall be carried to such depth that sufficient material will be left above the designed grade to allow for compaction to this grade. Likewise on embankments, sufficient material shall be placed above the designated grade to allow for compaction and settlement.

The'Town of Landis is requesting a letter of concurrence from the North Carolina Wildlife Resources Commission (NCWRC) to obtain a 404 pernlit from the U.S. Army Corps of Engineers. The NCWRC has reviewed information provided by the applicant. These comments are provided in accordance with provisions of the Clean Water Act of 1977 (33 U.S.C. 466 et. seq.) and the Fish and Wildlife Coordination Act (48 Stat. 401, as amended; 16 U.S.C. 661- 667d). Lake Corriher (17 acres) is a raw water supply not open to public fishing for the Town of Landis. Work is to be accomplished while the lake is drained, then the lake will be refilled. We have no objection to the project as proposed provided that adequate erosion control measures are implemented to prevent sedimentation of downstream waters.
