The sediment and erosion control practices are to be installed prior to any major soil disturbances, and maintained until permanent protection is established. Road surface flows from the site should be dissipated with tracking pad or appropriate measures during adjacent road shoulder regrading. Contractor is responsible for the installation and maintenance of all soil erosion and sedimentation control devices throughout the course of construction. 2.Catch basin inlet protection must be installed and operating at all times until tributary areas have been stabilized. When possible flows should be stabilized before reaching inlet protection structure. Timely maintenance of sediment control structures is the responsibility of the Contractor. 3.All structures shall be maintained in good working order at all times. The sediment level in all sediment traps shall be closely monitored and sediment removed promptly when maximum levels are reached or as ordered by the engineer. All sediment control structures shall be inspected on a regular basis, and after each heavy rain to insure proper operation as designed. An inspection schedule shall be set forth prior to the start of construction. 4.The locations and the installation times of the sediment capturing standards shall be as specified in these plans, as ordered by the Engineer, and in accordance with the latest edition of the "New York Standards and Specifications for Erosion and Sediment Control" (NYSSESC). 5.All topsoil shall be placed in a stabilized stockpile for reuse on the site. All stockpile material required for final grading and stored on site shall be temporarily seeded and mulched within 7 days. Refer to soil stockpile details. 6.Any disturbed areas that will be left exposed more than 7 days and not subject to construction traffic, shall immediately receive temporary seeding. Mulch shall be used if the season prevents the establishment of a temporary cover. Disturbed areas shall not be limed and fertilized prior to temporary seeding. 7.All disturbed areas within 500 feet of an inhabited dwelling shall be wetted as necessary to provide dust control. 8.The contractor shall keep the roadways within the project clear of soil and debris and is responsible for any street cleaning necessary during the course of the project. 9.Sediment and erosion control structures shall be removed and the area stabilized when the drainage area has been properly stabilized by permanent measures. 10.All sediment and erosion control measures shall be installed in accordance with current edition of NYSSESC. 11.All regraded areas must be stabilized appropriately prior to any rock blasting, cutting, and/or filling of soils. Special care should be taken during construction to insure stability during maintenance and integrity of control structures. 12.Any slopes graded at 3:1 or greater shall be stabilized with erosion blankets to be staked into place in accordance with the manufactures requirements. Erosion blankets may also be required at the discretion of Town officials or Project Engineer. When stabilized blanket is utilized for channel stabilization, place all of the volume of seed mix prior to laying net, or as recommended by the manufacturer. 13.To prevent heavy construction equipment and trucks from tracking soil off-site, construct a pervious crushed stone pad. Locate and construct pads as detailed in these plans. 14.Contractor is responsible for controlling dust by sprinkling exposed soil areas periodically with water as required. Contractor to supply all equipment and water. 15.Contractor shall be responsible for construction inspections as per NYSDEC GP-0-020-001 and Town of Yorktown Code. MAINTENANCE OF TEMPORARY EROSION AND SEDIMENT CONTROL STRUCTURES: N.Y.S.D.E.C. GP-0-15-002 EXPOSURE RESTRICTIONS - States that any exposed earthwork shall be stabilized in accordance with the guidelines of this plan. 1.Trees and vegetation shall be protected at all times as shown on the detail drawing and as directed by the Engineer. 2.Care should be taken so as not to channel concentrated runoff through the areas of construction activity on the site. 3.Fill and site disturbances should not be created which causes water to pond off site or on adjacent properties. 4.Runoff from land disturbances shall not be discharged or have the potential to discharge off site without first being intercepted by a control structure, such as a sediment trap or silt fence. Sediment shall be removed before exceeding 50% of the retention structure's capacity. 5.For finished grading, adequate grade shall be provided so that water will not pond on lawns for more than 24 hours after rainfall, except in swale flow areas which may drain for as long as 48 hours after rainfall. 6.All swales and other areas of concentrated flow shall be properly stabilized with temporary control measures to prevent erosion and sediment travel. Surface flows over cut and fill areas shall be stabilized at all times. 7.All sites shall be stabilized with erosion control materials within 7 days of final grading. 8.Temporary sediment trapping devices shall be removed from the site within 30 days of final stabilization. MAINTENANCE OF PERMANENT CONTROL STRUCTURES DURING CONSTRUCTION: The stormwater management system and outlet structure shall be inspected on a regular basis and after every rainfall event. Sediment build up shall be removed from the inlet protection regularly to insure detention capacity and proper drainage. Outlet structure shall be free of obstructions. All piping and drain inlets shall be free of obstruction. Any sediment build up shall be removed. MAINTENANCE OF CONTROLS AFTER CONSTRUCTION: Controls (including respective outlet structures) should be inspected periodically for the first few months after construction and on an annual basis thereafter. They should also be inspected after major storm events. DEBRIS AND LITTER REMOVAL: Twice a year, inspect outlet structure and drain inlets for accumulated debris. Also, remove any accumulations during each mowing operation. STRUCTURAL REPAIR/REPLACEMENT: Outlet structure must be inspected twice a year for evidence of structural damage and repaired immediately. EROSION CONTROL: Unstable areas tributary to the basin shall immediately be stabilized with vegetation or other appropriate erosion control measures. SEDIMENT REMOVAL: Sediment should be removed after it has reached a maximum depth of five inches above the stormwater management system floor. TOPSOIL: Existing topsoil will be removed and stored in piles sufficiently as to avoid mixing with other excavation. Stockpiles shall be surrounded by erosion control as outlined on these plans. The furnishing of new topsoil shall be of a better or equal to the following criteria (SS713.01 NYSDOT): 1.The pH of the material shall be 5.5 to 7.6. 2.The organic content shall not be less than 2% or more than 70%. 3.Gradation: SIEVE SIZE % PASSING BY WGT. 2 INCH 100 1 INCH 85 TO 100 1/4 INCH 65 TO 100 NO. 200 MESH 20 TO 80 PERMANENT VEGETATIVE COVER: 1.Site preparation: 1.1.Install erosion control measures. 1.2.Scarify compacted soil areas. 1.3.Lime as required to ph 6.5. 1.4.Fertilize with 10-6-4 4 lbs/1,000 S.F. 1.5.Incorporate amendments into soil with disc harrow. 2.Seed mixtures for use on swales and cut and fill areas.
