These measures might include but are not be limited to the folbwing: • From October 1 to April 30, no soils may rert�ain exposed for aare ttan 2 days. From May 1 to September 30,no soil may remain exposed for more than 7 days. • Materials,equipment,and other resources shall be on site nt all times, in adequate quazrtities to immediately stabilize all soil. • Denuded areas shall be Govered by mulch, sod,plastic,or otl�et BMP's as per the City of Evereri's �tormwater Management manual. • Soil stockpiles shall be stabilized or protected with sediment retentan BMPs within 24 hours of formation to prevent soil loss. • Grading and coc�struction shall be timed and conducted in stages to minimi�e soil exposure. • The contractor shall establish a permanent vegetative ground cover to cornrol soil erosan and to survive severe weatt�er conditions on all areas of land disturbance not othenvise permanently stabilized by impen7ous surfaces ot othr.r means. • The contractor shall maiutain and repair as t�ecessary atl temporary and pernianent emsion and sodimentation control BMPs to assure tk�eir continued perfomiance through consttudion acceptance and extending to the release of all associated wananty security and mauitenance security. • Before performing any grading or clearing,the contractor shall mark, in the field, the limits of all proposed clearing and grading, critical areas and the'v buffers,trees to be retained,and drainage courses. • The contractor shall protect storm sewer inlets receiving storm water runoffduring construction so that water will not enter the inlet without first being 6ltered or othenvise treated to minimize the amount of sediment entering the inlet. � The contractor shall route storm water nuaff from disturbed areas of the site through sediment ponds,traps or other sediment retention BrdPs prior to discharge from the site. Tt►e BN[Ps shall be installed as the first step in grading,and shall be in operatan before any other site disturbance occurs • The contractor shall preservc a vegetated buffer strip around the lower perimeter of the site. . The wntractor shall design and construct temporary and permanent BMPs adequate to prevent erosion of outlets, adjacent stream banks, slopes and downstream reaches. • The contractor shall implement fully the erosion and sedimentation contml plan at each stage of site development. 4 �
