Storm Drain Pump Stations and Systems Upgrades
- Project typeCapacity Improvements
Project Descriptions
The Corporation Way System Upgrades and Pump Station, West Bayshore Road Pump Station, and West Bayshore Road Trunk Line Improvements projects are three of the highest-priority storm drain projects identified in the City’s 2015 Storm Drain Master Plan and 3 of the 13 projects identified on the 2017 ballot measure.
During a 10-year storm event, the two outfalls that convey storm runoff from East and West Bayshore Road onto Adobe Creek do not function as intended due to water pressure in the creek. Without the pump stations, this area is unable to drain until the creek levels recede, which is typically several hours after the rainfall stops. Additionally, the existing 15-inch and 24-inch storm drain pipelines do not have the capacity to convey the projected storm runoff generated by a 10-year storm event.
Scope of Work
The design of the three projects were advertised as one package to avoid redundant analysis and for cost savings. Schaaf and Wheeler Consulting Civil Engineers (Consultant) was selected to provide the design, prepare plans and specifications, and to provide construction administration service during construction.

Project Status
In June the consultant completed the design and the construction documents. The project was advertised for construction first in July and no bids were received. The project elements were clarified, and the project was advertised for a second time in August. Only one construction bid was received from a general contractor and the construction costs were 50% over the engineer’s estimate. Staff has since revised the scope and will rebid the project in December 2024, for a third time. Assuming competitive bids are received the contract will be awarded in January 2025. Construction could take up to 15 months and all three projects should be completed by Spring 2026.
