Description of proposed erosion control BMP's: <br /> Clearing,grading,and temporary erosion and sediment control plans have been prepared as part of the drainage <br /> plan drawings.However,since a construction site is dynamic it will be necessary to reassess the erosion control <br /> BMP's during construction and install additional measures when necessary. <br /> Proposed temporary measures possible for this project will include the following BMP's: <br /> Installation of stabilized rock construction entrance. <br /> Straw mulch,hydroseed or other mulching and planting method to stabilized unworked areas. <br /> Retention of vegetation around site. <br /> Silt fence <br /> CB inlet protection. <br /> Permanent measures to reduce or eliminate erosion or water quality degradation will include the following <br /> BMP's: <br /> Paving all traffic areas (Asphalt) <br /> Permanent landscaping in pervious areas. <br /> Limiting cut and fill slopes to 2:1 maximum and 3:1 maximum where exposed to standing water. <br /> Routine maintenance and inspection of the grounds and response to developing problems. <br /> The listed erosion control BMP's will be engineered for anticipated conditions in compliance with The City <br /> of Everett and DOE guidelines.With proper installation,maintenance and inspection the proposed BMP's should <br /> result in minimal impact to the surrounding environment.The County retains the authority by code to require additional <br /> measures should the existing measures prove insufficient. <br /> SITE GRADING/EROSION CONTROL RISK ASSESSMENT <br /> Area proposed to be cleared/worked: approx. 0.6313 acres <br /> Average slope for the site: 5% <br /> Erosion Hazard of Soil low <br /> Critical Areas downslope No <br /> Site is upstream of an ESA Stream No <br /> Based on the above information and the fact that the construction site runoff will be collected on-site, <br /> and with the implementation of the BMP's listed and that if site conditions warrant,additional BMP's can <br /> be implemented as corrective measures the Risk Category for this site is Low Risk. <br /> With the BMP's listed in section B and shown on the site plan,it is anticipated that this site will have <br /> little impact on the downstream system. <br /> V. Source Control Plan <br /> The following worksheet is completed by checking the appropriate boxes for all activities that will or may <br /> occur at the project site. <br /> Following the spread sheet is a list of the required and suggested BMP's for each activity. <br />
