Notes

Areas around the Loop Track were well-vegetated, including Outfall 34. Side slopes of Basin 4 were mostly well-vegetated; the low-flow channel had a sandy bottom. Erosion, gullies were observed around the slotted box outfall structure in Basin 4. Reddish-brown staining was observed on the outfall structure indicating sediment-laden water may have risen several ft. in the basin, creating potential for discharge to SW9 & Stream 5. The N. end of the storm water conveyance/retention basin along the E. side of the intermodal yard was well-vegetated. The levee at the N. end of the E. conveyance/ retention basin, & the slopes from the levee to the outfall/culvert/wingwall structure at SW9 were well-vegetated. Slopes around Outfall SW9 were mostly well-vegetated, but channel bottoms below outfall pipes at Outfall 9 were bare sand. A rip-rap flume down the large eastern slope had failed near light pole 115, & sediment had accumulated in the E. conveyance. A slump slope failure had occurred near light pole 125, & sediment had accumulated in the E. conveyance below the slump. A large, sparsely vegetated area was observed in the vicinity of light pole 129 above the E. conveyance. Slopes around Outfall SW12 were mostly well-vegetated. Water in Stream 6 was clear over a sandy bottom. Upper slopes & side slopes of Basin 3 were stabilized & well-vegetated; the only unstable areas were sandy bottoms of low-flow channels in the basin. Recommend diligent re-stabilization of the above areas.
