For these inlets, if pavement is constructed adjacent to the structure or if the area adjacent to the inlet is changed such that the wattle type filter is no longer effective, it shall be the responsibility of the Contractor to ensure that an appropriate method is used instead. For example, the wattle filter could be reused, or a gravel-block inlet filter may be installed. It will be left to the discretion of the Contractor as to whether replacement of any inlet filter is necessary. Inlet protection should be inspected regularly for tears that can result in sediment entering an inlet. Inlet protection should also be inspected for sediment accumulation upstream of the inlet, and sediment should be removed when the less than half of the capacity is available, or per manufacturer specifications. The Contractor shall provide inlet protection for all proposed inlets as they are installed (Phase II implementation). Erosion Control Blankets (Phase II) A temporary degradable rolled erosion control product composed of natural flexible fibers shall be used on all seeded slopes 4:1 and greater (excluding mulched shrub bed areas). Erosion control blankets should be utilized to provide erosion control and to facilitate vegetation establishment. During installation, it is important to ensure that no gaps or voids exist under the material and that all corners of the material are secured using stakes and trenching. Stakes should be made of materials that are biodegradable. Continuous contact between the product and the soil is necessary to avoid failure. Erosion Control Blankets should be inspected regularly for signs of erosion, including beneath the mat. If voids are apparent, they should be filled with suitable soil. Inspections should also identify loose or damaged stakes, as well as loose portions of the blanket. If deficiencies are found, they should be repaired or replaced. At a minimum, Erosion Control Blankets shall be installed as deemed necessary in areas with steeper than or equal to 4:1 slopes. Concrete Washout Area (Phase II) A concrete washout should be provided on the site. The washout can be lined or unlined excavated pits in the ground, commercially manufactured prefabricated containers, or aboveground holding areas. The concrete washout must be located a minimum of 400 feet from any natural drainage way or body of water, and at least 1000 feet from any wells or drinking water sources. Washout areas should not be located in an area where shallow groundwater may be present. Contractor shall clearly show the desired location and access to the Concrete Washout Area on the Stormwater Management Plan - Dynamic Site Plan. Contractor shall place a Vehicle Tracking Pad if the selected location for the Concrete Washout Area is detached from pavement. Clear signage identifying the concrete washout should also be provided. The Concrete Washout Area should be inspected regularly. Particular attention should be paid to signage to ensure that the area is clearly marked. Confirmation that the washout is being used should also be noted to ensure that other undesignated areas of the site are not being used incorrectly as a concrete washout. An appropriate location for the concrete washout area is located near the access points onto Hobbit Street. This location is a suggestion only, and can be relocated at the discretion of the Contractor.
