Yoast Access Road, there were some rills that should be monitored to confirm they pose no <br />threat to the stability of this section. Noxious weed populations continued up this drainage as <br />well. <br />Culvert YA -4a has significant downcutting at the outlet. Too much vegetation growth and <br />sediment deposition is choking the outlet and needs to be removed. The sediment came from <br />above the culvert. The inlet is in good condition with rip -rap. <br />Culvert YA -5 needs some fill at the inlet because water has eroded below the culvert and piping <br />could occur (see photo 7965). The outlet and drainage charnel appear to be in good condition. <br />Culvert YA -5a (crosses County Road 51D and runs parallel to Yoast Access Road) is in good <br />condition, but overgrown vegetation is choking the outlet. This vegetation should be removed <br />and the culvert cleaned. <br />Culvert YA-6 has new rip -rap at the outlet to help prevent erosion. At the inlet, significant <br />erosion between the culverts and the overlying road requires further stabilization work (see photo <br />7966). Past measures to abate the erosion have failed (straw wattles staked into the ground have <br />been torn out of the ground from runoff and erosion). This culvert system is situated at the low <br />point along a stretch of Road LU -3A. We discussed the possibility of adding small drainages or <br />water bars above both sides of YA -6 to divert water off of the road upgradient from this low <br />point. <br />Culvert YA -7 inlet is clear; however, sediment needs to be removed from the outlet (see photo <br />7967). <br />Culvert YA- Undesignated runs parallel to Yoast Access Road and is placed under a road leading <br />to fenced animal shelters and rangeland. This culvert is accumulating sediment and vegetation <br />and needs to be cleaned. <br />Culvert YA -8 has minor erosion on the right side of the inlet and some sediment accumulation at <br />the outlet. The outlet needs to be cleaned out (see photo 7968). <br />Culvert YB -1 is operating as designed. Road width at this location is 22 feet. <br />Pond 10 drainage with rip -rap is in good shape; a culvert in this area is a bit choked with excess <br />vegetation. The outlet to the wetland area is fully functional and had a trickle of water running <br />through it at the time of inspection. The flume and continuous recorder in the wetland are in <br />good condition. <br />Culvert YB -2 was in good working order, although the inlet of the culvert was a bit damaged. <br />Rip -rap installed from the outlet to the edge of an oak scrub area was functioning as designed; no <br />erosional features were observed. Road width measured 20 feet at this location. <br />
