Over​view

The Sunnyvale/Chandworth Storm Drainage Improvement Project, with a drainage area of 640 acres, was broken down into three smaller projects: Lilly Mill, Chandworth and Tattersall.

The Lilly Mill Storm Drainage Improvement Project will reduce street and structure flooding throughout the neighborhood and address stream erosion to provide a more natural, stable stream system.  Located within a drainage area of approximately 100 acres, the project will replace and/or rehabilitate aging infrastructure and provide adequate drainage system capacity.

Estimated Cost: $11,800,000​*

*includes all costs associated with this project such as planning and design, utility relocation, consultant fees, permits, construction, and landscaping.

The project team will manage the project through several phases. Specific work is conducted during each phase and public involvement is emphasized throughout the process. Learn more about project phases.
