Severn/Tyndal Storm Drainage Improvement Project

The purpose and need for this construction project is to improve the storm drainage infrastructure (i.e. pipe systems and culverts) to reduce flooding and to enhance degraded stream reaches to reduce erosion and improve water quality. The project area is located in the overall Sunnyvale Storm Drainage Improvement Project (SDIP) area. The scope of work for the Tyndale Avenue project includes replacing a corrugated metal pipe between Tyndale Avenue and Chandworth Road. Replacement of the system is needed to address reported house flooding in the immediate area. The upgrade to the system also allows for the construction of the upstream improvements currently in design from the Storm Water’s queue that will address seven requests for service of failing infrastructure and flooding requests. Approximately 500 linear feet of 48-inch to 66-inch corrugated pipe will need to be replaced to address the undersized and deteriorating system in the Severn Avenue project area.
