REPORT TO COUNCIL

Receive a Report of an Emergency Repair Project to Reconstruct a Damaged Stormwater Outfall and Restore the Embankment of Stevens Creek at Mockingbird Lane. The Project is Urgent to Ensure Public Safety and the Operation of the Storm Drainage System (Policy SN-1.3).
Report
BACKGROUND
A series of severe winter storms occurring between December 2022 and March 2023 resulted in a significant erosion incident at the intersection of Stevens Creek and Mockingbird Lane on March 18, 2023. The erosion led to the loss of a stormwater outfall and a substantial section of the connected storm pipe. It also created a steep cliff beneath the dead-end roadway and damaged the asphalt above it. Figure 1 provides an overview of the site's location, the extent of the impact, and image of the damage.
Recognizing the urgency of the situation, the City Manager declared a local emergency on March 30, 2023. The declaration was subsequently ratified by the City Council (Resolution RTC 23-0501) on April 4, 2023
