NO. DATE: 8/14/2019 i 07 �71 SPECIFICATIONS FOR CONSTRUCTION FOR THERESA BAICH SHORELINE STABILIZATION MECKLENBURG COUNTY, NORTH CAROLINA These specifications are to be made a part of detailed engineering plans of the proposed shoreline stabilization. No changes or deviations from these plans and specifications shall be allowed without a written amendment, in advance of the change, from the DSWC design engineer. CLEARING AND FOUNDATION PREPARATION: Limits of construction as flagged and discussed during pre construction conference shall be cleared and grubbed of trees, logs, stumps, roots, brush, boulders, sod, and debris. Satisfactory disposal will be made of all debris. All stumps and all roots exceeding one (1) inch in diameter shall be removed to a minimum depth of one (1) foot. The foundation area shall be roughly shaped and compacted before the placement of any fill material. The contact surface shall be thoroughly scarified so that the first layer of fill material will be properly bonded to the foundation when compacted. If they are suitable, excavated materials shall be used in the permanent fill. Foundation areas shall be kept free of standing water when fill is being placed on them. CUT ROCK (BUNKER BLOCKS) AND NON WOVEN GEOTEXTILE INSTALLATION: Excavate the back of the stable foundation (closest to the slope) slightly deeper than the front to add stability to the structure. Install geotextiles so that they lie smoothly on the prepared foundation with a minimum of 3 inches of sand -gravel bedding material over the geotextile to prevent movement.. Place the blocks so that the vertical joints are staggered between the blocks of adjacent rows and layers by at least one-half of a cell length. A tieback into the bank and bed will be required to protect the structure from undermining or scour. FILL MATERIALS AND PLACEMENT: The fill and any other required excavations shall be to the lines and grades shown on the plans or as staked in the field. The material placed in the fill shall be free of sod, roots, frozen soil, stones more than six (6) inches in diameter (except for rock fills), and other objectionable material. Borrow areas shall be from an approved site with all necessary permits. The placing and spreading of fill materials shall be started at the lowest point of the foundation and the fill brought up in horizontal layers not to exceed eight (8) inches in thickness prior to compaction. The fill shall be constructed in continuous horizontal layers. The slope of the bonding surfaces shall not be steeper than 3 horizontal to 1 vertical. The bonding surface shall be treated the same as that specified for the foundation so as to insure a good bond with the new fill. The distribution and gradation of materials shall be such that no lenses, pockets, streaks, or layers of material differ substantially in texture or gradation from the surrounding material. The moisture content of the fill material shall be adequate for obtaining the required compaction. Material that is too wet shall be dried to meet the requirements, and material that is too dry shall have water added and be mixed until the requirement is met. It is generally preferred to use material slightly wetter than optimum than dryer than optimum. Construction equipment shall be operated over all areas of each layer of fill to insure that the required compaction is obtained. If a minimum required density is specified, each layer of fill shall be compacted as necessary to obtain that density. A sheeps-foot roller or a mechanical roller -compactor shall be used as needed to obtain the required compaction. Areas that cannot be compacted by the above shall be carefully compacted to a density equivalent to that of the surrounding fill by manually directed power tampers or plate vibrators. Fill materials compacted with manually directed power tampers or plate vibrators shall be placed in horizontal layers not to exceed four (4) inches in thickness prior to compaction. SEEDING, MATTING AND CRITICAL AREA PLANTING: A protective cover of vegetation shall be established on all exposed surfaces, native vegetation is required on all shoreline stabilization projects. See construction details and seeding specification sheet for seed bed preparation, lime and fertilizer requirements and rates of seeding mixture. Temporary vegetation may be used until conditions permit establishment of permanent vegetation. An erosion control blanket, North American Green Bio -net SC 150 BN or an equivalent shall be installed from the top of the cut block to the top of the slope. If an equivalent blanket is selected specification sheet must be submitted and approved by the design engineer. See seeding specification sheet for details on soil amendments, seed mixture and rates. Critical area planting plan will be provided by the local soil and water conservation district office. Depending on time of construction it may be necessary to make arrangements for plantings months after construction is complete. GENERAL: Construction operations shall be carried out in such a manner and sequence that erosion and air and water pollution are minimized and held within legal limits. All work shall be conducted in a skillful and professional manner and the completed job shall present a workmanlike appearance. SPECIFICATION NOTE CONCERNING PUBLIC UTILITIES: An appropriate utility representative should be contacted prior to starting the construction work. The fact that utilities may not be shown on the drawings cannot be taken as assurance that utilities are not present at the site. The information pertaining to utilities (if any) which is shown on the drawings is primarily based upon data provided by the owner, and neither the Division nor the Soil and Water Conservation District make any representation concerning the existence or nonexistence of any utility at the site. The contractor should personally closely inspect the site to determine the existence or nonexistence of utilities within the construction area and also discuss utility locations with the owner. All parties should understand that any liability for damages resulting from the disruption of utility service caused by the construction activities rest between the owner, contractor, and the affected utility. N RESPONSIBILITIES OF: LANDOWNERS All shoreline stabilization projects require a twenty foot (20ft ) undisturbed native vegetative buffer adjacent to the practice for the duration of the contract period. The landowner shall maintain the fill slope including making repairs of washes and gullies, reestablishment of vegetation and removal of debris until adequate vegetation has been established. The landowner will acquaint himself with the provisions of these plans and specifications to determine that the completed project will fulfill his/her intentions. Where benefits are to be received from Government agencies, a preconstruction conference, inspection and approval by the design engineer or appointed representative with appropriate job approval authority is mandatory. It is the landowner's responsibility to obtain all permits required for construction of this project. Staging area for this project will be located in cul -da -sac and front portion of landowners natural area. It is the landowners responsibility to make sure the home owner association is notified and if necessary and any requirements are made know to the contractor. CONTRACTORS The contractor will acquaint himself with the provisions of these plans and specifications, conditions at the site that may affect his schedule of operation, and the location and meaning of all stakes on the site. Failure to do so will not relieve him of the difficulties and costs pursuant to satisfactorily completing the work in compliance with these plans and specifications and any written or verbal contract with the landowner. All benchmarks, grade and line stakes will be left undisturbed and protected by the contractor to facilitate construction and inspection. The contractor, weather permitting, will schedule his work so that he will start on the agreed date, and work will be a continuous operation until satisfactorily completed. All damages occurring to completed works or materials, by the elements or otherwise, during construction will be the responsibility of the contractor. The contractor will pay for partial or damaged work and/or replaced materials damaged from any cause. Absence of inspections during construction will not relieve the contractor form completing the work in strict compliance with these plans and specifications. Upon completion of the work, before moving his equipment, the contractor will request a final inspection by the landowner and the design engineer or appointed person with appropriate job approval authority. The contractor will then receive approval that all work had been completed satisfactorily and/or he may complete those items that vary from the plans and specifications in order that a final inspection will result in approval. 3 DIVISION OF SOIL AND WATER CONSERVATION The DSWC and its employees are in no manner a party to any verbal or written contract between the landowner and the contractor. DSWC employees, with the limit of personnel available, will inspect and advise on technique during construction to assure satisfactory compliance with the plans and specifications. DSWC employees will, upon reasonable notice, conduct a final inspection for strict compliance with all plans and specifications concerning this project. Inspection will determine the satisfactory completion of work so that (1) approval may be given for the eligibility of the landowner to receive benefits from any Government agency concerned with this structure, (2) final payment may be made to the contractor. 4 Steve Troxler North Carolina Department of Agriculture Commissioner and Consumer Services Division of Soil and Water Conservation Date: August 13, 2019 To: Permitting Agencies From: Cindy M. Safrit, PE Subject: Baich Shoreline Stabilization CCAP # Vernon N. Cox Director Existing site conditions of the Baich Shoreline is an existing sandy beach 10 foot wide for approximately 150 feet. The landowner would like to preserve the existing condition of the shoreline to the extent possible while still stabilizing the eroding banks. To design a stable slope, trees at the top of the slope will have to be removed, a retaining wall will be installed. The toe of the wall along the sandy beach will be 2.8 feet higher than normal water level. It is customary to place rip rap at the toe of seawalls or retaining walls that go below normal pool for fish habitat. However, as this section of the retaining wall the toe will very seldom be under water, therefore rip rap should not be necessary. Thank you so much for help. Sincerely, Cindy M.
