In the summer of 2019, the City of Napa began replacing several Highway 29 freeway crossings that broke during the 2014 South Napa Earthquake with new mains to reestablish circulation within the water system.

Conn Dam Water Spillway Repairs - Phase II

In November 2018, the City addressed damage requiring immediate repair to Conn Dam Spillway (Phase I). The work performed under Phase I involved the repair of edge spalling and crack sealing and was completed in December 2018. The repairs completed as part of Phase I withstood subsequent heavy winter rains, prompting the City to continue with the Phase II evaluation and repairs.

In January 2020, the City entered into an agreement with GEI Consultants to perform the Phase II evaluation of the Spillway. Phase II will involve subsurface exploration of the Spillway and will be used to guide the necessary maintenance related repairs to ensure the Spillway continues to perform as designed and intended.
