Receive report on the expenditure of the Hall Road culvert repair and Laureles Grade slide repair.
Report
RECOMMENDATION:
It is recommended that the Budget Committee receive the report of the Hall Road culvert repair and Laureles Grade slide repair.
SUMMARY:
During March 2016 rain events several County roads experienced storm damage that required immediate action to maintain the roads open to traffic and safeguard the safety of the motorist. This report outlines the expenditures incurred for the Hall Road culvert repair and Laureles Grade slide repair.
DISCUSSION:
On March 21, 2016, RMA staff was called out to the Community of Las Lomas to investigate a sharp dip in the westbound lane of Hall Road. Upon review of the site, it was apparent that a corrugated-metal pipe carrying storm water across the road had collapsed. The culvert pipe was an arch pipe measuring 49-inch by 33-inch in diameter and 150 feet in length. Given the number of underground utilities lines in the immediate vicinity of the culvert, a number of water lines and sewer lines were also at risk of being affected. The cost to replace the culvert and related work was initially estimated at $200,000. However, as indicated in the table below, the costs were higher than anticipated due to a number of unmarked utilities that where uncovered during the trenching of the road. These unmarked utilities considerably slowed the progress of the work. The work was completed by Granite Construction Company.
