All emergent planting areas <br />will be overexeavated 36" below finished grade and bacRfillec; with organic <br />oompost soil only. Final grade finish will be 'scalloped" or rough In character <br />resembling mounds and depreesionb in the soil. All nniehed grading will be <br />approved by Wetland Biologist or Environmental Designer. <br />In Site A mitigation area, the exlstine wetland ditch will be graded along with the <br />remaining mitigation area. The Final finished grade will match the proposed grades <br />as shown on the plan. <br />Habitat features such as snags w/ nest boxes and bill ices will be Installed as per <br />details shown on sheet 1IM-5 and field located by the Wetland Blologlat or <br />Environmental Designer. At least five large coniferous trees will be topped or <br />girdled to produce snags. Three conlferous trees w/ 12" min. trunk size will be used <br />for bill loge. <br />TEMPORARY EROSION AND SEDIMENT CONTROL NOTES <br />Prior to any grading In the mitigation areas, sedimentation and temporary <br />construction fences must be constructed and located as shown on the plan. <br />After finai grading or final installation of mitigation landscapa vegetation, the <br />entire mitigation area will be protected from erosion by hyai-oekseding with <br />Barclay low grow mix lees plant schedule) to establish a erase groundcover. <br />SEDIMENTATION FENCE <br />E>qSWETLTAND A -- ` \ \ V _/ / ����`/ \ <br />TEMPORARY CONSTI`A4 ON FENCE/ <br />1> —/ \ \ FMIT�ZF CLEARINCs/ <br />/ <br />I r \ / (TYPICAL)/ / <br />\ <br />4i <br />Et' Ei�NT AREA \ \ , / \ <br />(TT'RJCAL) I / \ \ \ <br />//SNACsIUd/ / �� / DOWN LOGS <br />NEST BOX � (TYPICAL) <br />/ (TYPICAL) <br />r � <br />r <br />4-18 <br />WOOBRIDGE <br />BY THERS — — — —' <br />SILL LOG <br />(SEE DETAIL SHEET W1-5) <br />PAv� ==kt=ATRl�w \ <br />I <br />v \\PATH Y OTC ERS <br />\/ \/ \/ <br />4j6�_ \\\ \\ \\\\ <br />I \ <br />�V \/ r=AST�1Cz <br />UlE7�AN1D \ \ <br />EXI3INCs I/ \ <br />WETLAND A/B <br />0 <br />Cn <br />0 <br />CA <br />L0 <br />N <br />to <br />CV <br />Vl CO <br />W� <br />U <br />O <br />U <br />A � <br />N a <br />Ga <br />U1 w <br />z� <br />W <br />A <br />�itD <br />-, <br />A " <br />17 IONS: APPD. <br />4-Z-BS - Revised per <br />meeting w/ CltTor Everett <br />4-1-W <br />DATE: <br />2-6-98 <br />DESIGN: <br />GBK <br />DRAWN: <br />GBK <br />CHECKED: <br />BCF.MBE <br />REVISION <br />NUMBER: <br />SCALE: 1'=20' <br />Zj� MMATION AREA A PROJECT NUMBER: <br />TCWX0084 <br />0 20 0 8 0 STATE TOF <br />O <br />r WASHINGTON SHEEP N0. <br />REGISTERED <br />LANDSC E ARCH( ECIftd 7m m C <br />—2 <br />�— — MARK B.
