o a <br /> 0 <br /> Element#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 /> As this project site is located west of the Cascade Mountain Crest,the project will be managed <br /> according to the following key project components: <br /> Inspection and Monitoring <br /> • All BMPs shall be inspected,maintained, and repaired as needed to assure <br /> continued performance of their intended function. Site inspections shall be <br /> conducted by a person who is knowledgeable in the principles and practices <br /> of erosion and sediment control at least once every calendar week and within <br /> 24 hours of any major rainfall event. This person has the necessary skills to: <br /> • Assess the site conditions and construction activities that could impact <br /> the quality of stormwater, and <br /> • Assess the effectiveness of erosion and sediment control measures used <br /> to control the quality of stormwater discharges. <br /> • A Certified Erosion and Sediment Control Lead shall be on-site or on-call at <br /> all times. <br /> • Whenever inspection and/or monitoring reveals that the BMPs identified in <br /> this SWPPP are inadequate, due to the actual discharge of or potential to <br /> DAVID EVANS AND ASSOCIATES,INC. <br /> GRANDVIEW APARTMENTS CLUBHOUSE MARCH,2017 <br /> STORMWATER SITE PLAN PAGE 15 <br />
