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 Tattersall 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 130 acres, the project will replace and/or rehabilitate aging infrastructure and provide adequate drainage system capacity.
