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 Chandworth Storm Drainage Improvement Project will replace failing infrastructure plus reduce street and structure flooding throughout the neighborhood. The project is located within a drainage area of approximately 200 acres.
Storm drainage box culvert installation is underway working towards Rhodes Avenue. Rock breaking will continue as needed. Guardrail installation on Chandworth Road will begin late-January. View the January mailer(PDF, 364KB) for more information.
