Acre Short Plat Stormwater Site Plan <br /> All temporary erosion and sediment control BMPs shall be removed within 30 days after the final site <br /> stabilization is achieved or after the temporary BMPs are no longer needed.Trapped sediment shall <br /> be removed or stabilized on site. Disturbed soil resulting from removal of BMPs or vegetation shall be <br /> permanently stabilized. <br /> 12. Manage the Project <br /> Erosion and sediment control BMPs for this project have been designed based on the following <br /> principles: <br /> • Design the project to fit the existing topography, soils, and drainage patterns. <br /> • Emphasize erosion control rather than sediment control. <br /> • Minimize the extent and duration of the area exposed. <br /> • Keep runoff velocities low. <br /> • Retain sediment on site. <br /> • Thoroughly monitor site and maintain all ESC measures. <br /> • Schedule major earthwork during the dry season. <br /> In addition, project management will incorporate the key components listed below: <br /> Phasing of Construction: <br /> • The construction project is being phased to the extent practicable in order to prevent excessive <br /> soil erosion, and,to the maximum extent possible, the transport of sediment from the site during <br /> construction. <br /> • Revegetation of exposed areas and maintenance of that vegetation shall be an integral part of <br /> the clearing activities during each phase of construction, per the Scheduling BMP (C 162). <br /> Seasonal Work Limitations <br /> • From October 1 through April 30,clearing, grading, and other soil disturbing activities shall only <br /> be permitted if shown to the satisfaction of the local permitting authority that silt-laden runoff will <br /> be prevented from leaving the site through a combination of the following: <br /> ■ Site conditions including existing vegetative coverage,slope, soil type, and proximity to <br />! receiving waters; and <br /> i <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 authority <br /> 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 the soil <br /> or result in the removal of the vegetative cover to soil; and <br /> October 15, 2021 <br /> Page 11 <br />
