. Construction stagin, areas musi oc located outside of environmentally sensitive areas and their <br /> buffcrs, uniess detcrmined by the Planning Director to be infeasible. Streams, wetlands, buCfers. <br /> staging areas and construction limits shail be clearly shown on const;uction plans. Conswction <br /> limits shall be clearly marked in the ficld with orange construction fcncing. <br /> . Work shall be done so as to minimize turbidity, erosion, and other water quality impacts. <br /> . Proper erosion and sediment control measures shall be Collo�ved to prevent sediments Crom <br /> entering creeks or wetlands. Erosion control measures shall bc approved by the Depariment of <br /> Engineering and Public Services and/or agencies with jurisdiction. Measures may indude, but not <br /> bc limited to, placing ply���ood across the area where equipment will operate; mulching the <br /> wetland areas where equipment will operate; placing wood chips atop a Ilexible mat to help <br /> prevent compaction (the wood chips ar.d mat must be removed following conslruction); placing <br /> silt fences and hay bales bchvecn construction areas and all adjacent ���etlands and slreams; and <br /> placing ecology blocks between consWction areas and streams or wetlands whcn a tcmporary fill <br /> is used for roads, ete. <br /> • Erosion control mcasures shall be in place and inspecled prior to commencement of work. All <br /> erosion control stnictures shall Uc inspccted regularly to ensure they are maintained in working <br /> ordcr. <br /> . VVhen operating machinery in or near water, extreme care shall bc taken to prevent any petrolcum <br /> products, cement, chemicals, or other toxic or deletcrious materials from entering the water. If a <br /> spill does occur, work shall be stopped immediately and Gcology's Spill Response Section <br /> contacted. <br /> . Equipment mainlenance shall not occur in or adjacent to wctlands and strearns. <br /> . Aftcr construction,thc sitc must be retun�ed to its original grades. Carc must bc takcn to not drain <br /> wetlands or aiter water flows or patterns. <br /> . Whenever feasible, if wedand plant specics arc not invasivc, thcy should be removed prior to <br /> construction and placcd aside in a shady damp location, such as under wet burlap sacks. <br /> Following construction, thcy should be replaced in die wetland area. <br /> • Rc��egetation: At a minimum, crosion control revegetation is rcquired in all cleared areas and <br /> should include herbaccous ground cover that does not interfere with establishment of native <br /> vegetation. If]ong-tenn revegetation is required, it should be accornplished during the next most <br /> favorable time of year for the paRicular vegetation to ensure thc highest level oC success. (Note: <br /> If revegetation docs not occur immediately following recontouring of the site, adequate erosion <br /> con[rol measures must bc taken.) Native species compatible with preconstruction vegetation <br /> patterns shall bc used for revegelation. Degraded emergent sites, such as Reed canary grass fields, <br /> shall be replan:�d with specics that are representative of a higher quality emergent, scrub-shrub or <br /> forested wetland. Lf revegetation is required, monitoring should occur once a year for a minimum <br /> oC h��o years. (SEPA �Vatcr, Plant and Animal, and Land and Shorelinc Usc Policies) <br /> �i3 <br />
