PURPOSE: The purpose of this report is to provide specifications for the measures and methods proposed to control accelerated erosion and sedimentation resulting from the land disturbing activities of more than one contiguous acre in size. This report is prepared for conformance with the requirements of the Sedimentation Pollution Control Act of 1973. Other regulatory program requirements are carefully considered in the site design, but this report does not assure nor imply conformance with any other rules, laws, or regulatory standards. 2. SCOPE OF WORK• This report will include a general description of existing conditions, proposed uses of the site, proposed changes to the site to accomplish the proposed uses, and the proposed measures to be taken for the control of accelerated erosion and sedimentation during land disturbing activities. The use of this report will require a review and familiarization with the plans and appendices, as they will clarify and supplement the narrative information. The services provided by this report are intended solely for the benefit of .the Financially Responsible Person. Nothing contained herein shall confer any rights upon or create any duties on the part of the design firm toward any person other than the Financially Responsible Person. The Contractor(s) conducting the land disturbing activity, as delegated by the Financially Responsible Person, is solely responsible for the detailed means, methods, procedures, sequencing, co-ordination, job safety, and failures to carry out that work in conformance with this report, specifications, and plans. Observations and inspections by the design firm does not assume nor imply any assumption of any supervisory responsibilities by the design firm. This report shall constitute supplementary conditions for the work specified herein and if any other provisions are found to conflict with these provisions, the most restrictive provision shall apply. This report, and any specifications and plans which this report is part of or contingent to, shall be on site at all times that any of the specified work is being actively prosecuted on the site. The Sedimentation Pollution Control Act of 1973 and resulting sedimentation control programs are performance oriented. Storm water run-off events exceeding mandatory design guidelines can and do occur. The Contractor shall actively prosecute the goal of minimizing off - site sedimentation by the installation, maintenance, and amendment of measures in conformance with this report and the State Erosion and Sediment Control Planning and Design Manual with the intent of precluding off -site accelerated sedimentation. NR-2 3. PROJECT DESCRIPTION: Ocean -Sound Village is a proposed 31 lot detached single family residential subdivision located at the intersection of NC Highway 210 and NCSR 1568 within the corporate limits of the Town of North Topsail Beach in Onslow County. The total site area is 28 acres. The project is bounded on the West by Hampton Colony and on the East by an undeveloped portion of the George Jeffreys property. The project boundary includes approximately 1370 liner feet of ocean frontage. The Development of Ocean -Sound Village will consist of constructing two streets, Oceanview Lane and Soundview Lane. In addition, the developer will construct water and sewer utilities, including a sewage pump station. The total disturbed area will be 2.8 acres for the roadway and utility construction. The project landscape consists of sand dunes interspersed with native vegetation such as beachgrass, live oaks, and other maritime vegetation. The remains of the old abandoned NCSR 1568 also exist within this area. In addition, there are several wetlands areas extending into the property. These areas have been mapped and are shown on the plans. No development will occur within the wetlands areas. Silt fences will protect these areas from adjacent develop- ment. 4. SEDIMENT CONTROL STRUCTURES AND MEASURES: The following structures, facilities, and measures are proposed for control of accelerated erosion and sedimentation. All of the specified facilities and measures may not be used on any one site or portion of a site but are provided in case of changes in work scope, unpredictable changes in site character, or ineffectiveness of the planned measures. The specifications provided for the facilities and measures should assist in determining which measures are most appropriate when additional measures are considered desirable. A. Construction Sequence: Sequencing a timely execution of construction activities is considered the most effective means for controlling accelerated erosion and sedimentation. Controlling the source of sedimenta- tion is a more efficient and cost effective approach to provid- ing for control of off -site accelerated sedimentation resulting from construction activities. The following construction sequence(s) will define the relative timeliness of installing sediment control measures and the timely stabilization of the contributing watersheds. No work shall be prosecuted until the relevant permits and approvals are obtained. Relevant permits and approvals shall include but not may be limited to: (a) sewer system extension approval by the N.C. Division of Environmental Management (DEM); (b) water system extension approval by the N.C. Department of Environment, Health and Natural Resources (c) storm water control approval by DEM; and (d) sediment control plan approval NR-3 by the N.C. Land Quality Section (LQS) (e) Major CAMA Permit approval by the N.C. Division of Coastal Management. Prior to any land disturbing activities, a preconstruction conference shall be established at a place and time acceptable to LQS personnel. Sediment Control Construction Operation Sequence: 1. Clear, and grub area for stabilized construction entrance at entrance to NCSR 1568. Construct stabilized construction entrances as shown on plans. Clear and grub remaining portion of right-of-way for Soundview Lane and Oceanview Lane and install silt fences indicated on plans. Rough grade street profiles. Install road side swales. 4. Install silt fence at sewage pump station site. 5. Install water & sewer utilities and pump station as indicated on plan. 6. Seed and mulch or otherwise stabilize all disturbed areas within 30 working days of completing any phase of grading thereon. 7. Enlarge, amend, and maintain sedimentation control measures as needed for revised watershed conditions and effective restraint of off -site sedimentation. 8. All sedimentation control devices and facilities not displaced by watershed stabilization shall be maintained at the full functional capacity until the contributing watershed is stabilized. The approximate construction duration is expected to be between 90 and 120 days. Work is expected to begin imme- diately upon receipt of all necessary permits. B. Stabilized Construction Entrance: This facility shall be constructed as indicated on the plans. It shall be placed at all locations of construction access to the project from public right-of-ways or adjacent properties. If the gravel pad is found to be ineffective, other measures such as enlarging the entrance or washing all construction vehicle tires shall be done to prevent sediment tracking onto public rights -of -way or other paved areas serviced by storm drainage collection systems. As permanent stabilization is established and progresses to the interior of the project, the construction entrance or similar means shall be progressively located to remain at the interface of the construction activi- ties in progress an the project areas that are stabilized. This detail may also be used to stabilize contractor staging areas inside the project boundaries. NR-4 C. Silt Fences:, Fabric silt fences shall be constructed as per the detail on the plans. These devices may be used at storm drain inlets not subject to concentrated storm run-off and any other areas designated that typically do not receive diffused surface water flow in quantities greater than one cubic foot per second per ten foot sections of the proposed silt fence. Silt fences shall be inspected after every rain and at intervals not exceeding one week. Accumulated sediment shall be removed and placed in approved spoils areas. Any deterioration of this device shall require immediate repair to a state of 100% functional stabili- ty. D. Finish Grades: All cut and fill grading shall be maintained to provide positive surface drainage throughout the construction process in the areas of the construction activities. All outlets constructed for this purpose shall be provided with sediment control devices. All cut and fill areas shall be shaped to final grade in one continuous operation. Cut and fill slopes which shall be stabilized with vegetation requiring mowing maintenance, shall be no steeper than 3:1 (horizontal: vertical). No cut or fill slopes in or immediately parallel to rights -of -ways or easements shall exceed 2:1. The side slopes of excavated trenches in cohesionless soil materials shall not exceed 2:1. All cut or fill slopes subject to concentrated storm water run-on shall be provided with diversions or slope drains to protect the slope face. E. Protective Ground Cover: Areas to be protected by permanent vegetative cover shall include but shall not be limited to any soil area denuded of a protective cover during the construction and not otherwise stabilized by improvements during the development construction process. Any undirected disturbed areas shall be stabilized at the expense of the -Contractor. In cases using grass for permanent stabilization, the work shall include but not be limited to appropriate tilling of the area, the application of soil amendments, sowing of seed, and placing of appropriate mulch. Areas to be stabilized by landscape plantings and turf shall be installed in conformance with the landscaping and turf specifications. Areas to be seeded for grass stabilization shall be given an initial application of acricultural lime at a rate of at least 4,000 pounds per acre, superphosphate at 800 pounds per acre, and 12-4-8 grade fertilizer (or equivalent) at a rate of 600 pounds per acre, all of which shall be thoroughly mixed with the soil. After the area to be seeded is brought to proper finish grade, the entire area shall be tilled on the contour to a minimum depth of 4-inches by discing, harrowing, or other NR-5 approved means. Following tillage, all large debris and stones shall be removed and the surface leveled to a smooth aspect. Dense or compacted soil areas and cut grade soil areas shall be ripped at greater than 6-inches of depth with a spring toothed ripper or similar equipment after finish grade but before tillage. Severely compacted surfaces shall be ripped to at least 1.2-inches of depth. No compacted soils subject to grassing for stabilization shall be covered with soil fill until ripped. Finish grades on slopes exceeding 30% shall. be rough- ened parallel to contours to maximize surface storage and minimize run-off. Upon completion of ground and soil preparation work, a grass seed mixture of 100 pounds per acre of "Rebel" fescue, 25 pounds per acre of common bermuda grass, and 10 pounds per acre of centipede grass shall be sown. Bermuda grass seed shall be in an unhulled (with hulls) condition from September 1 to April 1 and be in a hulled (without hulls) condition at all other times. Substitutions for "Rebel" fescue will be considered acceptable if the substituted tall fescue variety has no ratings less than 115" as determined by the USDA 1983 Tall Fescue Trials or more recent USDA trial data. This shall be followed by placing a suitable cover of clean grain straw or approved equivalent mulch at a rate of 1 1/2 to 2 tons per seeded area. In the case of sloping areas or other areas of more concentrated storm water run-off, the straw shall be stabilized by the application of an asphalt emulsion or other approved binding materials. Alterna- tive methods such as hydro -seeding and hydro -mulching will be considered on an individual basis. The Contractor shall guarantee a full stand of grass over the entire seeded area. A full stand of grass will be considered acceptable when areal cover is at least 95% at a uniform minimum height of 3 inches. The Contractor shall then top -dress the stand of grass with a minimum of 300 pounds per acre of 12-4-8 fertilizer (or equivalent). Annual weed grasses and grain weeds shall not be considered part of the minimum areal cover, and seedling stands shall not be considered acceptable until the stand of specified species reaches a state of uniform post - seedling maturity. If straw mulching results in competing stands of grain, maintenance shall include mowing of the grain weed stand to a height of three (3) inches prior to reaching a height of seven (7) inches. Unacceptable grass stands shall be overseeded, after aeration by spiker, at half the original rate, as many times as necessary to establish an acceptable stand. Temporary protective cover may include solid plastic sheeting, porous mats, coarse aggregate, spraying of soil stabilizer concentrates, temporary grass cover, heavy applications of straw mulch, and other measures that protect bare soil surfaces from accelerated erosion. Commercial products shall be utilized in conformance with the manufacturers recommendations. Clean grain straw shall be applied uniformly at a minimum rate of. five (5) tons per acre. Methods and measures utilized will be considered acceptable only within the specific context of the use for each NR-6 individual circumstance and the effectiveness in controlling accelerated erosion. F. Roadside Swales: The roadside swales for this project are designed to retain all stormwater runoff. There will be no direct connection of the swales to the wetland areas. The swales will be constructed with minimal grade. Given the low flows and sandy soil condi- tions which allow for rapid infiltration, velocities in this situation are negligible.
