These features are intended to minimize the opportunity for sediment to leave the site via <br /> stormwater or on vehicles. The construction of these features is one of the first items <br /> required in the "Construction Sequence". Mulch will also be used on the exposed soil as <br /> necessary to limit erosion. <br /> 5: Stabilize Soils <br /> The "Construction Sequence" calls for the stabilization of soils that remain unworked for <br /> certain lengths of time based on the time of year. Stabilization techniques may include but <br /> not limited to mulching, plastic sheeting or hydroseeding, notes have been added to the <br /> plan regarding protection for the stockpile area if necessary. <br /> 6: Protect Slopes <br /> All slopes on site during construction are required to be protected with mulch or other <br /> means as specified in the construction sequence. <br /> 7: Protect Drain Inlets <br /> CB inlet protection will be installed on all new catch basins and yard drains on and <br /> adjacent to this project. <br /> 8: Stabilize Channels and Outlets <br /> A straw bale check dam will be placed downstream from site ahead of the channel along <br /> 10th Drive SE to further stabilize the existing channel. <br /> 9: Control Pollutants <br /> No outside chemicals are expected to be necessary for the construction of this project. All <br /> vehicles working on and around the site would need to meet the State requirements for <br /> emissions. <br /> 10: Control DeWatering <br /> DeWatering is not expected for this project. <br /> 11 : Maintain BMPs <br /> The construction supervisor will be responsible for maintaining all BMPs during <br /> construction and working with the County to relocate or add BMPs as necessary as site <br /> conditions change. <br /> 12: Manage the Project <br /> It will be the responsibility of the Contractor and Developer to manage this project and <br /> coordinate with the County Inspector and Engineer. <br /> Inspection and Monitoring: <br /> Site inspections shall be done by a person who is knowledgeable in the principles and <br /> practices of erosion and sediment control. The person must have skills to first assess the <br /> site conditions and construction activities that could impact the quality of stormwater, and <br /> second assess the effectiveness of erosion and sediment control measures used to <br /> control the quality of stormwater discharges. <br /> Whenever inspection and/or monitoring reveals that the BMPs identified in the <br /> Construction SWPPP are inadequate, due to the actual discharge of or potential to <br /> discharge a significant amount of any pollutant, appropriate BMPs or design changes <br /> shall be implemented as soon as possible. <br /> Drainage Report—9227 4th Ave W Everett,WA 98204 <br /> Nov. 10,2022 Page 12 <br />
