Former Sunnyside Nursery Multi-Benefit Project

 

About the Project

The Ross Valley Flood Protection & Watershed Program has been working to find and implement solutions to address the type of flooding which occurred most recently during the winter of 2005-2006, but which has repeatedly impacted the valley for decades (watch video). Recent studies (read reports) characterizing the flooding problem have demonstrated that a holistic approach is required to diminish or eliminate the effects of the most severe floods. The studies emphasize the need for a multifaceted way of addressing flooding which would both reduce the amount of floodwater reaching the creek, as well as increase the capacity of our creeks and floodplain to carry floodwaters to the bay.

In an effort to reduce the amount of floodwaters which would reach the creek, sites have been identified (read report) for temporarily storing floodwaters during rare and infrequent events which could otherwise flood downstream towns and neighborhoods. These detention sites would work together along with other improvements to help reduce flooding. One potential site which has been identified is the growing grounds for the former Sunnyside Nursery.

 

Status & Next Steps

At its meeting on July 12, 2016, the Board of Supervisors entered into an agreement with the owners of the former Sunnyside Nursery at 3000 Sir Francis Drake Blvd. to purchase the property. This summer, the District will be talking with neighbors and assessing the general feasibility of using the site for detention basin prior to completing the purchase.

Any project at the former Sunnyside Nursery would aim to provide multibenefits in addition to those related to the flood risk reduction goal; these include creek, habitat, and possible recreational enhancements. A community-based participatory planning and design process would be used to engage residents and stakeholders, seek their input, and provide a pathway for them to help shape the project prior to its implementation.

public feedback process: obtain feedback, use feedback, present preliminary concepts
