(District I1) [CDD-CP# 06-25] Project No. 0672-6R6113, 0672-6R6114 DATE: April 11, 2006 PAGE: 2 of 2 FISCAL, IMPACT: The project will not impact the General Fund. It will cost approximately $250,000, which will come from Road funds. REASONS FOR RECOMMENDATIONS AND BACKGROUND: The project consists of repair to two sections of road, their associated guardrails, and failed embankments on the downslope side of the road to the creek. Damages were caused during the December 31, 2005 storm event when compromised culverts allowed water to sheetflow across the roadway,causing erosion,undermining of the road and slope failure on the downslope embankment. The repair includes two segments that have failed: Guardrail#10 and Guardrail#11. Guardrail#10: Repair to this failure will include either placement of inter-locking blocks,rock slope protection, or a retaining wall, then backfilling behind the wall, and recreating the slope with earthen fill. Each option will have approximately the same footprint. Drainage facilities must be rebuilt within the slope and on the opposite side of the roadway where flow frons a small ravine enters the culvert. The road will be repaired, and guardrails replaced at this location after repairs to the slope are completed. Guardrail 411: As with guardrail #10, repair to this failure will include placement ofinter-locking blocks, rock slope protection, or a retaining wall,then backfilling behind the wall and recreating the slope with earthen fill.Each option will have approximately the same footprint.Drainage facilities must be rebuilt within the slope,and on the opposite side of the roadway where water is captured in an inlet that drains the roadway, and water coming from the hillside. The road will be repaired, and guardrails replaced at this location after repairs to the slope are completed. Currently the lanes adjacent to both guardrails have been closed to traffic, and traffic must use one lane to pass. It can'be seen with certainty that there is no possibility that the activity may have a significant adverse effect on the environment. CONSEQUENCES OF NEGATIVE ACTION: Failure to approve the CEQA document will delay the needed repairs and may allow additional damage to occur at the County road facilities.
