The <br /> erosion potential of the site is influenced by four major factors: soil characteristics, <br /> vegetative cover, topography, and climate. Erosion/sedimentation control is achieved by a <br /> combination of structural measures, cover measures, and construction practices that are <br /> tailored to fit the specific site. <br /> Prior to the start of any grading activity upon the site, all erosion control measures, <br /> including installation of a stabilized constriction entrance, shall be installed in accordance <br /> with the construction documents. <br /> The best construction practice will be employed to properly clear and grade the site and to <br /> schedule construction activities. The planned construction sequence for the construction <br /> of the site is as follows, though is subject to change with the development of the project C- <br /> SWPPP: <br /> PHASE I: <br /> 1. Install stabilized construction exit(if applicable)and SWPPP Information Sign. <br /> 2. Install silt fence(s)and construction fence(s) on the site(as shown on the site map). <br /> 3. Prepare temporary parking and storage area. <br /> 4. Install appropriate inlet protection on existing storm drainage structures. <br /> Halt all activities and contact the civil engineer to perform inspection and certification of BMPs. <br /> General contractor shall schedule and conduct storm water pre-construction meeting with civil <br /> engineer,construction manager,Agency(ies)and ground-disturbing contractors before proceeding <br /> with construction. <br /> All exceptions noted on the BMP Certification form must be added to the first Daily report as a <br /> deficiency or deficiencies and resolved within 24-hours. BMPs CAN NOT be certified if any <br /> exception requires greater than 24-hours to resolve. <br /> Daily inspections and reporting must start the day of or immediately after BMP Certification. <br /> 5. Install additional BMPs including silt dikes, straw wattles, etc. as shown on the site map. <br /> 6. Demolish existing paving and foundations per the Demolition Plan, D-1.0 <br /> 7. Begin grading the site. <br /> 8. Start construction of building pad and structures. <br /> Phase II <br /> 1. Temporarily seed, denuded areas that will be inactive for 2 days or more during wet season <br /> (October 1 -April 30)or 7 days or more during dry season (May 1 —Sept. 30). <br /> 2. Install utilities, storm sewers, curbs and gutters. <br /> 3. Install appropriate inlet protection at all storm sewer structures as each inlet structure is <br /> installed. <br /> 4. Permanently stabilize areas to be vegetated as they are brought to final grade. <br /> 5. Prepare site for paving. <br /> 6. Pave site. <br /> Everett Mall Plaza Parcel III Retail Expansion Stormwater Site Plan Page 13 <br />
