Agenda Section: CONSENT CALENDAR File Number: 23-408 File Type: Staff Report Adopt a Resolution to Find Emergency Conditions Continue to Exist that Do Not Permit a Delay Resulting from a Competitive Solicitation for Bids and to Authorize the City Manager to Negotiate and Award an Emergency Construction Contract, to a yet to be Determined Responsible Contractor, for the Lake Chabot Road Upslope Repair Project, Project 2023.4020 COUNCIL PRIORITY ·Infrastructure ·Sustainability & Resiliency RECOMMENDATIONS Staff recommends the following: ·Find that substantial evidence exists of an emergency that will not permit a delay resulting from a competitive solicitation for bids and that the action is necessary to respond to the emergency; ·Authorize the City Manager or her designee to negotiate and award an Emergency Construction Contract to a yet to be determined responsible contractor, for the Lake Chabot Road Upslope Repair Project BACKGROUND The 2022-2023 winter storms caused severe erosion at two locations along Lake Chabot Road. At location 1, the upslope hillside of the road failed, depositing falling boulders and soil onto the roadway below. The eroded hillside is located immediately below two residential properties at 1700 and 1728 Astor Court. At location 2, a downslope slide eroded the hillside below the road creating a void up to the pavement edge. As a safety precaution, due to obstructing debris and the potential of additional falling rock onto the roadway at location 1 and loss of structural support to the above roadway at location 2, Lake Chabot Road was closed to vehicular traffic. At location 1, further hillside erosion has a strong potential to damage the two residential Astor Court structures. Repairs need to be conducted in dry weather and before the next wet season. Completion of the repair design occurred in July, 2023. Permanent repairs should be completed by November 2023, before the start of the next wet season. At location 2, the slide area must be repaired before the full roadway width can be reopened to vehicular traffic. Repairs at this location will not be implemented until after the next wet season; however, design efforts for this location will commence later in 2023.
