3) 1 n p 1 aces where 1 ow water cross i ngs must out 1 et on a potent i a l l y <br /> unstable fill slope, large durable rock will be placed at the <br /> outlet to the fill slope, if possible . <br /> 4) The decisions for placement of low water crossings must be based <br /> on maximum hydrologic stability . if long stretches occur without a <br /> crossing , large f lows will build up in the inside ditch and will be <br /> increasingly difficult to pass to the fill slope without problems . <br /> On the other hand, some areas will not accept a concentrated flow <br /> on the fill slope without erosion . These choices must be made in <br /> the field based on the hydrologic basins upstream and downstream, <br /> the nature of the natural drainages and the fill slopes , the road <br /> slopes and other factors . <br /> 6) in places where a low water crossing is desired and there is no <br /> need to backfill the cut material against an unstable cut slope, <br /> 'he material can still be placed against the cut slope, which will <br /> allow reclamation which more closely approaches the original <br /> contour . <br /> 7 ) Wherever gullies exist at culvert outlets , a reasonable attempt <br /> will be made at remediation. If an existing culvert outlet will be <br /> replaced by sheet flow across the road surface , the gully will be <br /> regraded by equipment if the slope allows . If it is too steep , <br /> slashed timber pieces will be lodged in the gully to help heal it <br /> naturally . In gullies at culvert outlets that w i 1 1 not be converted <br /> to sheet flow, slashed timber will also be placed in these to the <br /> extent reasonably possible. <br />
