Broadway Everett Expansion Storm Drainage Report <br /> November 16, 2022 <br /> Phasing of Construction <br /> The construction project is being phased to the extent practicable in order to prevent soil <br /> erosion, and, to the maximum extent possible, the transport of sediment from the site <br /> during construction. <br /> Revegetation of exposed areas and maintenance of that vegetation shall be an integral <br /> part of the clearing activities during each phase of construction, per the Scheduling BMP <br /> (C 162). <br /> Seasonal Work Limitations <br /> From October 1 through April 30, clearing, grading, and other soil disturbing activities shall <br /> only be permitted if shown to the satisfaction of the local permitting authority that silt-laden <br /> runoff will be prevented from leaving the site through a combination of the following: <br /> • Site conditions including existing vegetative coverage, slope, soil type, and proximity <br /> to receiving waters; and <br /> • Limitations on activities and the extent of disturbed areas; and <br /> • Proposed erosion and sediment control measures. <br /> Based on the information provided and/or local weather conditions, the local permitting <br /> authority may expand or restrict the seasonal limitation on site disturbance. <br /> The following activities are exempt from the seasonal clearing and grading limitations: <br /> • Routine maintenance and necessary repair of erosion and sediment control BMPs; <br /> • Routine maintenance of public facilities or existing utility structures that do not expose <br /> the soil or result in the removal of the vegetative cover to soil; and <br /> Activities where there is 100 percent infiltration of surface water runoff within the site in <br /> approved and installed erosion and sediment control facilities. <br /> Coordination with Utilities and Other Jurisdictions <br /> Care has been taken to coordinate with utilities, other construction projects, and the local <br /> jurisdiction in preparing this SWPPP and scheduling the construction work. <br /> Inspection and Monitoring <br /> All BMPs shall be inspected, maintained, and repaired as needed to assure continued <br /> performance of their intended function. Site inspections shall be conducted by a person <br /> who is knowledgeable in the principles and practices of erosion and sediment control. This <br /> person has the necessary skills to: <br /> Page 12 <br />
