/ OPTION 1 <br /> Reduce crest of fill slope and <br /> _z backfill against lower portion <br /> of cut slope. <br /> \ / OPTION 2 <br /> f�� ^ Leave fill alone. Dig new ditch <br /> inside current far enough to <br /> reduce travel width as desired and <br /> backfill ditch excavation against <br /> highwall at moderate slope . <br /> Final reclamation would entail elimination of all culverts , enlargement <br /> of water bars and ripping and seeding of reduced road surfaces . <br /> Additional grading might be required in some cases . <br /> Interim treatment of portal pads might entail some combination of debris <br /> clean up, removal of dilapidated structures , gravel surfacing, limited <br /> grading, and reseeding. At most portal sites , installation of additional <br /> sediment control measures at base of fill slopes will be necessary <br /> (dikes , sediment ponds , filter fences , etc . ) . Some measures obviously <br /> could be done fairly quickly and without significant modification of <br /> existing plan ( i .e. filter fabric fences) . Basic maintenance and repairs <br /> of existing road and portal drainage control structures as necessary to <br /> comply with currently approved plan will require immediate attention. <br /> 3. Upgrade Roads for Operational Use as Haulage Roads <br /> Slope stabilization and improved drainage would still be necessary, <br /> although road width reduction might not be appropriate. Maintenance plan <br /> would have to address method for ditch clean out and snow removal that <br /> will minimize spoil material being pushed over the outslope. This has <br /> negatively impacted steep slope revegetation efforts in the past. <br /> Additional culverts and/or rolling dips would be needed in a number of <br /> locations , along with other measures to reduce flow velocities and <br /> volumes as necessary to minimize erosion and allow sediment to be <br /> filtered out before road drainage reaches live water courses . Additional <br /> measures might include , but not be limited to lining road ditches with <br /> riprap or installation of rock chec:cs in eroding ditch segments , <br /> construction of sediment traps or ponds , and installation of filter fence <br /> barriers along the base of road fills which are adjacent to water courses . <br /> -z- <br />
