♦ 4 <br /> 5. DESCRIPTION OF PROPOSED EROSION CONTROL BMP's <br /> Minimum Requirement#2: Construction Stormwater Pollution Prevention Plan <br /> Clearing, grading, and temporary erosion and sediment control plans have been prepared <br /> as part of the drainage plan drawings. However, since a construction site is dynamic it will <br /> be necessary to reassess the erosion control BMP's during construction and install <br /> 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 or maintain the existing <br /> asphalt access during construction. <br /> • Straw mulch, hydroseed or other mulching and planting method to stabilized <br /> unworked areas. <br /> • Silt fencing <br /> • Retention of vegetation around site. <br /> • CB inlet protection. <br /> • Flag and protect infiltration areas from compaction. <br /> Permanent measures to reduce or eliminate erosion or water quality degradation will <br /> include the following 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 <br /> to standing water. <br /> • Routine maintenance and,inspection of the grounds and response to <br /> developing problems. <br /> The listed erosion control BMP's will be engineered for anticipated conditions in <br /> compliance with the City of Everett and DOE guidelines. With proper installation, <br /> maintenance and inspection the proposed BMP's should result in minimal impact to the <br /> surrounding environment. The City retains the authority by code to require additional <br /> measures should the existing measures prove insufficient. <br /> Thompson Short Plat 11-012 <br /> May 2011 Page 8 <br />
